The invention relates to irrigation systems.Known invention (SU authorship, 441387, CL E 02 B 13/02, 1972) containing the outlet with on it moving head, equipped with a flexible seal, and the camera provided with float level sensor bottom is for the prototype), contains located on the discharge chamber with elastic capacity, two shoulders lever, one arm of which is made in the form of a platform that is installed inside the chamber, and a device that regulates the access of water into the elastic capacity.A disadvantage of the known device is that the absence of the piston is not possible to create the necessary pressure to lift the fluid and the float level sensor does not provide cyclic operation of the device without penalization of the float.Technical solution to the problem is creating pressure to lift the fluid and providing the cyclic operation of the plant.The task is achieved in that the piston Autonomous water lift, containing located on the discharge chamber with elastic capacity, two shoulders lever, one arm of which is made in the form of a platform that is installed inside the chamber, and a device that regulates the access of water in the flexible container has a discharge pipe communicated through the pump with a discharge outlet, and a shoulder, two shoulders lever pivotally connected with the piston pump, the device regulates the access of water into the elastic capacity, made in the form connected to the outlet of the magnetic switch the lever together.The novelty of the claimed proposal is that in the design of a new set of features, namely the discharge pipe with a reciprocating pump and a magnetic switch that regulates the access of water into the elastic capacity, is achieved by the cyclic operation of the device using a magnetic switch, creates pressure and is lifting.According to the patent and scientific literature is not found similar technical proposal that allows to judge about the level of invention proposals.The drawing shows a diagram of a piston Autonomous water lift.The water lift consists of the outlet 1, is in communication with the pressure pipe 2 through the pump consisting of a piston 3 with the exhaust valve 4 and the cylinder 5 with the discharge valve 6. The piston 3 is connected through a hinge 7 with two shoulders lever 8, is divided into two shoulder hinge 9. The lever arm 8 is located in the chamber 10 and is designed as a platform 11, on which is located an elastic capacity 12 connected by a pipe 13 with the housing of the magnetic switch 14 having a valve 15, the inlet 16 and the outlet 17. Inside the switch seatsa to the housing of the magnetic switch 14. The lever 18 of the valve 15 is actuated by the lever 8, with which it is connected by means of a spring 20.Does the water lift in the following way. Under the action of the pressure of the water flows in a pipe of the outlet 1 and the inlet pipe 16. When the lever 8 is in position 11, and the lever valve 18 is in the lower (on) position, the valve 15 opens the access water out of the upstream pipe 13 in the flexible container 12. Filling capacity 12 exerts pressure on the pad 11, causing it to rotate around the hinge 9 and thereby lifting the piston 3. Lifting the piston 3 displaces the water in the discharge pipe 2. The gradual filling of the tank 12 causes movement of the lever 8 from position II to position I. when the lever 8 is the position I, the spring 20 is created extreme tension, and he pulls the lever valve 18 from the bottom of the magnet 19 and, turning, moves it to the top of the magnet 19. In this position, the valve 15 closes off the access water from the upper pool in the elastic capacity of 12, and goes to drain water through the discharge tube 17. Under the action of its own weight of the piston 3, the lever 8 from the position I gradually returns to the position II, and the space 11 presses on the elastic capacity of 12, vytesnenie, turning the valve 15 so that the water from the upper water again enters the flexible container 12. Thus, repeats the cycle, and water pressure pipe 2 is supplied to the pressure tank 21.The novelty of this design is that the design of the water lift incorporates a new magnetic switch using permanent magnets. Piston Autonomous water lift, containing located on the discharge chamber with elastic capacity, two shoulders lever, one arm of which is made in the form of a platform that is installed inside the chamber, and a device that regulates the access of water into the elastic container, characterized in that it has a discharge pipe communicated through a piston pump with a discharge outlet, and a shoulder, two shoulders lever pivotally connected with the piston pump, the device regulates the access of water into the elastic capacity, made in the form connected to the outlet of the magnetic switch, consisting of permanent magnets, the housing of the valve and lever valve with spring, connected with two shoulders lever.
