Device for watering houseplants
The invention relates to agriculture. The device comprises a reservoir and the storage tank, located one above the other, in and out of the storage tank siphon drain tube, water outlet directly to the flower pots. Siphon tubes are flexible capillary tube length from 0.40 to 1.20 m, made of insulation of cables with cross-sections from 0.50 to 0.12 mm2that simultaneously perform the role of water dispensers. Changing the height relative to stabilizirovannogo water level in the storage tank, the position of the tip of the capillary tube from which water drips, you can adjust the time between the drops and, consequently, the daily water consumption. The device allows automatic long-term drip irrigation of multiple (up to four) home flowers with simple regulation of the daily water consumption in the range of from 30 to 100 ml per day. Irrigation duration is from three to thirty days depending on the amount of water the plants specified water flow and the capacity of the tank capacity. 1 Il., 5 table.The invention relates to agriculture, is the shaft of plants, containing the inlet and the outlet, the cumulative capacity installed articulated and divided by a partition into two equal parts, and two siphon tubes coming out of them, which are used directly for watering plants. The disadvantage of this device is that it cannot quick changeover to another desired flow of water, because the dose initially is determined by the design of the product. In addition, with this device you can pour one or two plants.It is known  a device for watering houseplants, including the supply tank of liquid with dropper and the drive dose, made in the form of capacity placed in her flexible siphon tube, which is the outlet and is used to supply water to the plant. The disadvantage of this device, narrowing the scope of its application, are the complexity of the design and that it is most effective at maintaining just one plant, requiring small doses of irrigation.The prototype of the present invention is a device  for watering houseplants, which contains the cumulative capacity of the siphon tube and the fluid dispenser, made in the form of a conical vessel, more founded the accumulation tank is communicated between a siphon tube. The ends of the siphon tube extending from the storage tank equipped vessels-drives, and the other ends of the siphon tube installed in the storage tank at different heights through special nozzles. The device operates as follows. Irrigation water from the inlet flows into the fluid dispenser, where through the siphon tube is filled in the holding tank. From the latter through the siphon tube and the vessel drives the water goes directly to the plants. Due to the different height of siphon tubes placed inside the storage tank, is achieved in various fluid flow. The number of siphon tubes and vessels drives corresponds to the number of irrigated plants. The volume of the storage tank must be equal to the total consumption of water. The device allows simultaneous water several (more than two) home colours, however it is quite difficult to manufacture and it is difficult to vary the dose pour the liquid, since it is necessary to use extension nozzles of different length.The General principle of operation of these watering devices (and the prototype in particular) is the accumulation in one way or another predetermined amount (dose) of water, and potonie solves the problem of automatic continuous long-term irrigation of several domestic plants with very simple regulation of the daily consumption of water in a fairly wide range. The inventive device is especially useful for plant conservation in the long absence of the owners.The problem is solved in that the device for watering indoor plants containing tank and the storage tank and the siphon tube to drain water directly to the plants, as the siphon uses flexible capillary tube length from 0.4 to 1.2 m, made of conductors with a cross section of from 0.50 to 0.12 mm2, which simultaneously act as dispensers of liquid. The flow of liquid through the tube is subject to the law of Poiseuille flow :,where Vc is the volume flow of fluid through the cross-section of the tube, m3/s;R is the tube radius, m;L - tube length, m;P is the pressure drop along the pipe length, L, PA;is the dynamic viscosity of the fluid, PA(for water at 20With this value is 1,00510-3 PAC) .The equation shows that for a particular capillary tube (i.e., for fixed values of R and L) volumetric flow rate Vc, i.e., watering the dose is directly proportional to h the th flow of water in a fairly wide range.The drawing shows a General view of the proposed device for watering houseplants (to simplify shows a capillary siphon tube from several (up to four), provided with the device).In the holes of the storage tank 7 is fixed curved plastic tube 3 with missing through them flexible capillary tube 6. Cumulative capacity 7 fill watering with water to the specified label. Water must be clean and free of air bubbles. The upper reservoir tank 5 is also completely filled with clean water, screw on the neck of a special tube 4 with two outlet tubes that protrude above the plane of the tube, respectively, at 3-4 and 5-6 mm and an inner diameter of 6 mm Quick turn, establish the capacity of over 5 cumulative capacity of 7. After a short time the water level in the storage tank 7 destabiliziruetsya and will be automatically maintained during the entire time of irrigation. This happens as follows. If the water in the storage tank 7 for the two outlet tubes of the tube 4 at the same time, she's from the reservoir tank 5 has not translated, because it is held by atmospheric pressure. When the water level in the cumulative Ecotechnology ceases to touch the surface of the water, and through this tube, the atmospheric air flows into the reservoir tank 5. Water it begins to result in cumulative capacity of 7 up until the water level will not rise to the tip of the short outlet tube and will not block air flow through it in the reservoir tank 5. The described process is periodically repeated, and thus automatically maintains a preset water level in the storage tank 7 during the whole time of irrigation, i.e., until the water remains in the reservoir tank 5.The proposed watering device is run in the following way. The tip of the capillary siphon tube 6 is pulled by 7-10 cm below the water level in the storage tank 7, then take it in your mouth and suck the water until frequent drops 2. Then, sequentially retracting the tip of the capillary tube 6 (i.e., reducing its height h relative to the water level in the storage tank 7), gradually increased to the desired value of the time between the drops, which is set on the clock with second hand or stopwatch. The height h shown in the drawing, determines the value ofR in equation Poiseuille flow and consequently the rate of flow of water, i.e. irrigation dose. A simple retraction or W watering household plants. Similarly, setting the rest of the capillary tubes 6, if you want to pour some more flowers.The prepared device is installed near the plants so that the tips of the capillary tubes 6 was over flower pots 1 and 2 drops fell to the ground. It is desirable that the device is not exposed to direct sunlight, which can strongly heat the water in the storage tank 7 and to raise its level. After the water in the reservoir tank 5 will end, it should re-fill with clean water, set over accumulation tank 7, and the device is again ready for operation.The easiest accumulation tank 7 and tank 5 to make from plastic bottles with a capacity of 1.5 liters, but you can use other sizes. As the curved plastic tubes 3 can be applied tubes for cocktails. Special tube 4 can easily be made from ordinary plastic caps for plastic bottles. For that, it is necessary to drill two holes of appropriate diameter (~5.5 mm) and tightly into them, adjusting the height two piece vinyl PVC tubes having a length of 10-20 mm and an outer diameter 6 mmFlexible Capella the wire was determined according to the formula described based on the following practical considerations and design features of the proposed watering device.Pressure dropR ranged from 10 to 60 mm of water column (measured with a ruler), because the tip of the capillary tube, floating in the specified interval h, will always be above the edge of most flower pots.The length of the capillary tube L from 0.40 to 1.20 m Length less than 0.4 m does not have the device, since the tip of the tube can get out of the water in the storage tank 7. If the length is more than 1.2 m, the tubes begin to take in the accumulation tank a lot of space, through them, it is difficult to suck water mouth, and most importantly, they are difficult to manufacture and expensive.For the calculations were selected commercially available electric wire with a standard cross-section S of 0.75; 0,50; 0,35; 0,20; of 0.12 and 0.07 mm2 and plastic insulations. Tentatively took the inner radius of the capillary tube R equal to the radius of the wire and expected it from the value of the cross section of the electric wire by,where R is the capillary radius, m;S - conductor cross-section, m2.The calculation results are shown in table 1.When assessing the data obtained believed that daily consumption of water in the range from 30 to 100 ml one is the GLA.1 shows that theoretically discussed conductor (in addition to the cross-section 0.75 mm2) allow to obtain the daily water consumption in the above range.For the manufacture and testing of the proposed device were used flexible capillary tube, obtained from the electric insulating wires with a cross section 0,50; 0,35; 0,20; of 0.12 and 0.07 mm2. The estimated radius of the capillary tube Rp was determined by the nominal cross section of the wire, the actual radius R was measured using a reading microscope WORLD-1M at different sites along the length of the capillary and the data were averaged. The estimated daily water consumption Vp was calculated by the formula described using the values R measured pressure dropR and the length of the tube L. the Actual daily water consumption VF during the first days was determined using a measuring cylinder according to GOST 1770-74. On the basis of pre-defined for each capillary in the number of drops contained in 1 ml, watering devices have been configured on the daily water consumption of approximately 40-60 ml/day. The results are given in table.2. For comparison it also shows the data of the study capillary made of an electrical wire with a cross section of 0.75 mm2.From table.2 shows, otkolku not provide the required daily water consumption. Tests found that the actual daily water consumption is much less than that calculated by the formula Poiseuille flow. The reason for this phenomenon should be sought in the conditions of droplet formation at the tip of the capillary tube. To drop the force of surface tension of water, which tends to reduce the surface area, and hence the volume, and very significantly slows down the speed dropping. When the tip of the tube, from which emerged drops, dropped into the water (while maintaining the same value ofR), the water from the device ceased to flow drops and its consumption has increased significantly. This experience confirms the assumption. The detected deceleration of the flow of water in the process of dropping is not possible to use the proposed watering device capillary tube is obtained from a wire with a cross section of 0.07 mm2, although according to preliminary calculations (see table.1) it provides the widest limits of regulation in a given range of water flow. In addition, subsequent experiments showed that these capillaries fairly quickly (a few days) hammered solid impurities which are always present in tap water. Thus, for s long-term testing of the proposed watering devices on the basis of capillary tubes, made of conductors with cross-sections of 0.50; 0,35; of 0.20 and 0.12 mm2 and lengths from 0.4 to 1.2 m, i.e., over the whole range claimed parameters. The volume of the tank capacity was 1.5 l; the number of tubes was equal to three. You should specify that all devices in the beginning of the experiments were tuned to the desired daily consumption of water in the range from 50 to 60 ml. water Consumption was determined as the average of three values (number of tubes).From table.3 shows that a device with a capillary siphon tubes, made of conductors with cross sections from 0.50 to 0.12 mm and lengths from 0.4 to 1.2 m, provide smooth, uniform watering household plants during the whole time, which is calculated in terms of tank capacity.In addition, during the experiments it was found a significant effect of changes in atmospheric pressure on the daily water consumption. If the air pressure is increased, the water consumption was decreased and Vice versa. This is probably due to the formation of drops at the tip of the tube.For example, different types of cables with cross sections of 0.50; 0,35; of 0.20 and 0.12 mm2 studied the possibility of regulation of the daily water consumption for the account and enemy first few drops when configuring watering deviceswas determined by stopwatch. Experimental data are presented in table.4.These results suggest the possibility of regulation of the daily consumption of water in a fairly wide range by simply changing the value ofR, i.e., move the height h of the tip of the capillary tube, which confirms the previously assigned tasks.Presented in table.3 and 4 information to prove compliance of the claimed invention, the condition of “industrial applicability” under the current Patent law.For approximate settings watering devices on the required daily water consumption depending on the cross sections in table.5 shows the corresponding time between the falling drops, defined empirically.It should be noted that these times are approximate because the number of drops of water in 1 ml not strictly constant, but depends on the inner radius of the tip of the specific capillary tube, quality of cut, angle of inclination of the tube to the horizon, and so on,The analysis of scientific literature and patent documents in leading countries of the world (SS is the time of filing of this application has no known technical solutions, in its essential features are completely identical with the present invention. Therefore, it meets the condition of “novelty” under the current Patent law.The above analysis also did not reveal technical solutions that would have the signs consistent with the distinctive features of the claimed invention. So, from the present level of technology is not known for use in watering device for domestic plants as a siphon drain tube flexible capillary tubing length from 0.40 to 1.20 m, made of insulation of cables with a cross section of from 0.50 to 0.12 mm2, which simultaneously perform the role of water dispensers. Thus, the proposed solution meets the condition of “inventive step” by applicable law.Sources of information1.
