The invention relates to agriculture, namely, to an automatic device for watering indoor plants, in which the control mechanism used for the I weight of the flower pot with the substrate.

Known automatic device for watering plants in pots containing a movable platform with a counterweight, which is a flower pot, a container of water, a pipe for supplying water into the pot, valve and control valve in the water supply (US, 4060934, 06.12.1977).

The disadvantage of this device is the complexity of the implementation mechanism of the water supply and the unreliability of his work because of the large number of elements and the complexity of the whole structure due to the presence of the carrier base and a tripod.

The closest analogue - automatic device for watering plants in pots containing a movable platform, a system for conveying fluid, the electromagnetic valve mechanism positioned below the platform, mechanism for balancing weight capacity (US, 3168797, 09.02.1965).

The disadvantage of this device is the necessity of using an external electric power source, the complexity of the balancing mechanism.

The prior art watering machine in which to balance the weight capacity mechanism has a lever type (EN, 2053649 C1, 10.01.96).

However, in the known solution the pain is ask, accordingly, a large amount of water supplied to the evaporator capacity. In addition, the use of overhead distribution line and the rocker makes the device too bulky for use in the home.

Known automatic device for watering, in which mobile platform is placed on a fixed platform and is connected with it by means of a hinge (US, 5241786 A1, 07.09.1993).

However, this design is more complex.

Known automatic device for irrigation, in which the mobile platform is based on a swinging support and the other end rests on a spring-loaded support with counterbalance (DE, 550799, 20.05.1932).

However, this device is more complex in execution mechanism for balancing and valve mechanism. The proposed device is simpler in implementation and operation.

Known devices for irrigation, in which the displacement sensor is connected with the actuating mechanism for the feed water (SU, 1554 826 A1, 07.04.1990, SU, 284507, 14.10.1970, US, 3777976, 14.12. 1973).

However, these devices do not allow you to specify the amount of water supplied with a sufficient degree of accuracy.

Known from uruti in the operation.

The technical result of the invention is to improve the reliability of the device and its ease of use. This result is achieved by using the device mechanism for balancing capacity, made in the form of one of the options: lever type, spring-torsion type spring-supporting type, electronic type.

The invention

A counterbalancing mechanism lever type designed with four pillars supporting the movable platform and based on the United pairwise equal armed levers of the second kind, placed on a fixed support, while to the undercarriage of the levers by means of the hinge is attached to the free rocker arm with a counterweight, which represents a first class lever and supported on a movable carriage for the formation of different ratios of the shoulders, and the point of attachment of the hinge connected to the plunger valve mechanism.

A counterbalancing mechanism of a spring-torsion type made in the form of interconnected at the end by a hinge and spring torsion mobile platform and placed beneath the fixed platform, and a mechanism configured to adjust efforts torsion and mass PoA.

A counterbalancing mechanism of a spring-bearing type are made in the shape of a frame, one side of which is based on two swinging support, and the other side on the spring-loaded support with a valve mechanism, while the mobile platform is mounted on the surface of the frame can move it in the longitudinal direction.

A counterbalancing mechanism of the e-type made in the form of a weight sensor connected to a plunger movable platform, the signal from which is fed to analog-to-digital Converter, then to block the initial settings and adjustment, is compared in the comparator with the reference value of the mass balanced capacity, and depending on the result of comparison is enabled, the actuator valve system.

The invention is illustrated by the following examples.

In Fig. 1 shows a device for watering mechanism trim lever type.

In Fig. 2 - a device for watering with the mechanism of the balancing spring-torsion type.

In Fig. 3 - a device for watering with the mechanism of the balancing spring - supporting type.

In Fig. 4 - a device for watering mechanism trim electronic type.

To the arms 3 of the hinge is attached based on the sliding carriage 4 free rocker arm 5. The mobility of the carriage 4 sets alternating the correlation between the shoulders of the beam, forming raznoliki first class lever with a counterweight 6. The point of attachment of the hinge are connected by a thrust with the valve mechanism 7 system for the fluid 8, the opening and closing access of water to Slavnoi funnel 9. Pipeline supply system and valve mechanism positioned below the platform 2.

Random flower pot with the plant in the dry state is placed on the platform 2. The force of gravity through the rack platform 2 acts on the levers 3, which leads to the displacement of the rocker arm 5 to its extreme position. The sliding carriage 4, which support the rocker arm 5, by means of the threaded shaft (not shown) to move the trim system in a neutral position. Balancing occurs as a result of changes in the proportions of the shoulders the decomposition of the hyperbolic characteristic, that allows you to balance the weight really random flower pot at a constant mass of the counterweight 6. In the equilibrium position of the device the valve mechanism 7 is open. Then in the supply line serving the water, which through the open valve mechanism 7 and slevou funnel 9 is supplied to the pots. As a result of irrigation weight of the flower pot increases, which brings the system out of equilibrium. Platform 2 is lowered, locking the valve mechanism 7 and closing the water supply.

Further from the surface of plants and the natural substrate by the evaporation of moisture, and the weight of the pot is reduced until such time as opposed to the rocker arm 5 does not outweigh it. Platform 2 is raised, opening the valve mechanism 7, the cycle of the machine is repeated.

Calculations and tests have shown that the mass of one portion of the water supplied to the pot for one cycle of the machine, directly depends on the ratio between the shoulders of the rocker arm 5 and the geometry of the lever and counterweight. The test was obtained almost linear characteristic of the machine, showing a portion of water from 200 ml per pot 2 kg up to 1000 ml in a pot with a mass of 10 kg

Option 2

The device is spring-torsion type for watering potted R is built on the side of the hinge with movable upper platform 2, which is placed over the fixed. The lower part of the platform 2 is connected with the valve mechanism 7 feed line. The limiter move 11 limits the angle of rotation of the movable platform 2 on the axis of rotation 12. In the mechanism for balancing the weight of the flower pot, use a spring-loaded torsion arm control efforts 13 and additional regulation 14 of the mass portion of water supplied to Slavnoi funnel 9 for one cycle.

The adjusting screw 14 servings of water transferred to the position of the minimum number (Fig. 2 shows an arrow with a MINUS direction). Random pot plant is placed on the platform 2 device, the platform is in the down position.

The handle regulatory efforts torsion rotate in the direction of increasing efforts to move the platform in the upper position (shown in Fig. 2 is shown by an arrow with the direction PLUS). The screw 14 is switched to the position of maximum amount (the direction PLUS).

In the flower pot on the platform pour water in the usual way, for example, from a watering can in the quantity desired for a single portion of irrigation. Platform 2 still remains in the top position.

The adjustment screw portion 14 connecting the attachment is closed.

The force of the torsion adjusted to balance the weight of the pot, and the screw portion of water at the required resolution. In the piping system fluid supply to supply water.

The unit is ready for operation.

As a result of natural evaporation weight of the flower pot is reduced to until the spring force of the torsion will not exceed its weight and does not translate the platform 2 in the upper position. The valve mechanism 7 is opened and remains in this position until the force of the adjustment screw 14 is holding the platform in its upper position. The water enters the flower pot, the mass increases. Then the platform is lowered to the lower position, closing the valve mechanism and stopping the water flow. The cycle repeats.

Option 3.

The device is spring-bearing type for watering indoor plants in the flower pot shown in Fig. 3. The device consists of a frame 15 with the movable platform 2, which one party relies on a swinging support 16 in the form of two supports, and the other side of the spring support in which is mounted the valve mechanism 7. The mechanism for moving the platform 2 on the frame 15 in the drawing is not shown. In the trials used krupozavody feed screw, placed the pot is placed on a movable platform 2. The operation of the device is based on the fact that the mass of water applied to the pots in the process of watering, is added to the weight of the pot, increasing the load on the spring support containing the valve mechanism 7, and thereby renders it a control action. And back in the evaporation process, the mechanical load on the valve spring mechanism is reduced.

In the initial position of the mobile platform is displaced to the left (in the drawing) of the frame part 15. The load on the spring valve mechanism 7 ultimate - valve is closed.

To balance the component of the weight of the flower pot and the elastic force of the spring platform 2 is moved to the right (in the drawing) of the frame part 15. The value of the component of the weight of the flower pot decreases due to changes in the ratio arms of the lever of the second kind, which is formed between the swinging supports 16 and the point of application of force of gravity flower pot located at the geometric center of the platform 2. Platform to move until the force of elasticity of the spring valve mechanism 7 will not exceed the value of the component weight. Spring, stands up, raises his left part of the frame (shown by a vertical arrow), opening the valve mechanism 7. Water appears to the weight of the flower pot, increasing the value of the component of its weight. This happens as long as the value of this component will not exceed the force of elasticity of the spring. The left part of the frame is lowered, closing the valve mechanism 7.

The flow of water stops.

In the process of water evaporation from the surface of the plants and substrate weight of the flower pot is reduced, reducing the load on the spring up until the force of elasticity of the spring will not exceed it. Then the process repeats.

Option 4

The electronic device of the type for watering indoor plants in the flower pot shown in Fig. 4. The device includes a housing 17, on which is placed a movable platform 2, is mechanically connected to the sensor 18 weight, analog-to-digital Converter 19 polls the specified sensor and converts the received signal into data that depending on the current technological stage or stored in block 20 initial settings and adjustment, or act in a comparator 21 which compares with a reference mass values flowerpot in watered and dry conditions. Depending on the results of this comparison is actuated valve mechanism 7.

Flower pot with rastered analog-to-digital Converter 19, and these data by the user are stored in the unit's initial setting and adjusting 20 as the value ZERO. Next, the user adds the substrate measured in advance the desired amount of water, and similarly in the block 20 is memorized value UNIT. Then the machine goes into standby mode.

In the standby mode, the sensor 18 is polled at six-hour intervals. As soon as the value of the signal received from the sensor will be less than ZERO, the device enters the mode of irrigation, in which the valve mechanism 7 is open, the data from the sensor is read continuously and compared with the value of the UNIT. When this value is reached, the valve 7 is closed and the device goes into standby mode.

To supply irrigation water is used or tank connected to the device pipeline and placed above the device or piping connected to the public water supply through a gearbox, reducing the water pressure to a level not to exceed the technical parameters of the material from which the pipe and the valve mechanism of the device.
