The invention relates to agriculture and can be used for automatic watering of plants in limited areas: in greenhouses, the ridges in the gardens, etc.Known systems for watering plants (Pantielev J. H. Seasonal work is connected with a source of water through a valve or other control element.The disadvantage of these devices is the necessity of human involvement in the process of irrigation.A device prototype, containing a filling tank connected to a water source automatic node fill the tank with water, and with a distribution network through an electromagnetic valve controlled clockwork.The disadvantage of the prototype is that for controls necessary source of electrical energy is fairly high power, providing power to the solenoid valve during the time of irrigation. In terms of summer houses, greenhouses, hotbeds such a source is often at a great distance, or non-existent. Often, the electrical energy on plots served regularly or at certain times of the day. This leads to the impossibility of regular watering. The presence of clockwork (even electronic) complicates the operation of the device and reduces its reliability.The purpose of the invention is to simplify the design and improve reliability.This goal is achieved by the fact that famous watering device containing tank, site filling of the tank water associated with the water source, and racino in the hole, made in the wall of the tank in its upper part at the level of maximum filling of the tank, and the ascending branch is located at the bottom of the tank. Bearing tank placed under his head and shifted in a horizontal plane relative to the projection of the center of mass of the empty tank to the side of the siphon. Two stops are installed under the bottom of the tank on both sides symmetrically support. The height of the first focus located on the side of the siphon, less height than relying on the value of b a R/ d, where a is the distance from the top of the siphon until the water level, R is the distance between the support and the first extreme position, d is the distance from the tank wall to support. The height of the second stop is equal to the height. Tank top is made asymmetric about the vertical axis of the lower part of the tank, and the center of gravity of that part of the tank is displaced in the direction of the siphon for support. In the pipeline that connects the unit to the water source, made a calibrated orifice. The tank can be performed axisymmetric along the entire height. In the upper part of the tank in this case placed the empty hermetic vessel, rigidly connected with the wall of the tank and having a volume of parts lying below the level of maximum filling of the tank, V x h D, where h is the height of the liquid column in the tank, D is the diameter (width) of the tank, h is the magnitude of the offset is ka contains buffer storage capacity, input of which is connected through a discrete valve controlled by a level sensor, water source, and the output is through a pipeline with a calibrated orifice to the tank.The invention is illustrated in the drawing.The device consists of a storage tank 1, the inlet of which is connected through node 2, the filling of the tank, made in the form of a flush tank with float water level sensor and discrete valve, and an orifice 3 with a source of water supply, such as water. The output is made in the form of a siphon 4, passed through a hole in the wall of the tank 1 made at a height above the maximum water level. The ascending branch of the siphon is placed inside the tank 1 at its bottom, and the output connected to the irrigation distribution network 5. The bottom of the tank 1 is installed on the top of the support 6 having, for example, a triangular shape, are placed so that the peak is shifted relative to the horizontal projection of the center of mass of the empty tank in the direction of the siphon on the value of X. Under the bottom of the tank has lugs 7 and 8, the top of the first of which is placed below the top of the support 6 by the value of b a R/d, where a is the distance from the top of the siphon until the water level when the maximum filling b is flush with the top of the support 6. On top of the tank 1 from the side opposite to the siphon installed the hollow container 9, having a volume of V x h D and below the maximum water level in the tank.The device operates as follows.Empty the tank of the displacement of the support 6 relative to the projection of the center of mass is based on the stop 8. The filling of the tank 1 is in small portions, the volume of which is determined by the volume of the buffer capacity of node 2 filling of the tank, through a calibrated orifice 3, the size of which is selected so that the filling of the tank occurred during the day or other specified period of multiple days. While the water fills the lower part of the tank 1, the projection of the center of mass due to the symmetry of the bottom of the tank remains stationary. However, when the water reaches the tank 9, the position of the center of mass will begin to move in the direction of the siphon and, when part of the container 9, having a volume of V, becomes immersed in water, the position of the center of mass will shift towards siphon for support 6. The tank will lean in the direction of the trap and stand on the stop 7. At this point, you can populate siphon 4 water, and water flows by going into the irrigation distribution network 5. As runoff water, the projection of the center of mass of the tank will gradually move over the support 6, and the growing tank in the tank.The device allows you to automate watering a small garden plots, garden, etc. with long-term absence of the owner. 1.
