Description

The invention relates to agriculture and can be used for irrigating pastasters, supplying water to agricultural installations and for feeding gravity control systems. A water lifting device is known, having a source of water, a power supply pipe / feed line, a storage unit connected to the supply line of the storage unit in the lower part, a diverging pipe in which water rise is obtained by using the effect of a hydraulic shock 1. The disadvantage of this device is its inoperability at low pressure (tenths of a meter of water supply. The closest to the technical essence of the proposed is a lifting device that contains a diaphragm pump with a drive, the pump inlet is connected to power house with a water source, and the output is a storage tank, a tank and a supply pipe, the pump drive is connected to an additional energy source 2. The purpose of the invention is to improve performance by ensuring that the device operates without an additional energy source with a low-pressure water supply. This is achieved by the fact that in the water-lifting device, which contains a diaphragm pump with a drive, the pump inlet is connected to the water supply by the supply line, and the outlet to the water supply The pump drive is made in the form of a tilting tray and a twin-gravitational transmission unit with a swivel lever, with one horse arm on which the weight is fixed, connected to the rigid center of the pump membrane, a vessel with an opening in the bottom is mounted on the other end of the lever The drain end of the tipping tray is located above the vessel, and a cutting bar is installed above the tipping tray, connected to the supply pipe. In addition, the device is equipped with a control unit, made in the form of normally open and normally closed valves, the dampers of which are connected to the pivoting lever with the load, the valve of the normally closed valve being installed on the diaphragm, its chamber communicated through the throttle channel with the drain, the input is connected to the impulse piping to an outlet piping near the storage tank, and a normally open valve is installed in the supply piping. FIG. 1 is a diagram of the water lifting device in FIG. 2 diagram of the device with a control unit. 9 valves. The drive of the pump 3 is made in the form of a tilting tray 10 and a gravity transfer unit with a rotary lever 11. One end of the lever with a load 12 is connected to the rigid center of the membrane 7, at the other end of the lever there is a vessel 13 with a hole in the bottom above which the drain end of the tray 10 is located. Above the chute 10, a nozzle 14 is installed, which is connected to the power line 1. In this form, the device provides water lift provided that it does not require automatic switching on and turning off the water supply to the tank 5. Sometimes it is necessary to automatically turn on and off the water supply. A variant of the water lifting device in which it is provided is shown in FIG. 2. The device is equipped with a control unit 15, filled in the form of a normally open valve 16 and a normally closed valve 17, the dampers of which are connected to the pivoting lever 18 with a load 19. The valve flap 17 is installed on the membrane 20, its chamber communicates with the drain through the throttle channel 21. The inlet of the valve 17 is connected by the impulse piping 22 to the output piping 4 near the storage tank 5. The valve 16 is installed in the supply piping 2. The principle of operation of the device variant shown in FIG. 1 is as follows. Water through the pipe 14 flows into the tray 10. After its filling

it overflows and the water fills the vessel 13. Overcoming the force of the load 12, the lever 11 rotates and a suction stroke occurs in the chamber of the pump 3: water enters the chamber through the valve 8. After the tray tilts, it returns to its original position. Then the water flows out of the vessel 13 through the hole in the bottom and under the action of the load 12 the injection stroke is performed: the valve 8 is closed and through the valve 9 the water is supplied to the container 5. This cycle of operation is then repeated. From the tank 5, water flows to the destination through pipeline 6. The flow sections of the pipe 14 and the holes in the vessel 13 are chosen so that the time for filling the tray 10 is longer than the time for water to flow out of the vessel 13 through the hole in the bottom.

There may be various variations | 1ty of the device. For example, the reversing tray 10 may have several sections, and the flow area of the channel 1D may be large. When taking water from a stream or river, a small lowering of the water level (dam) is sufficient so that the water that has been spent in the device can return. In this case, when water is taken from its source to the dam, the waste water passes through a channel connected to the section behind the dam.

The operation of the device shown in FIG. 2 is similar.

The automatic switch-on of the shut-off of the water supply is carried out at

more different than tank 5, i.e. with hysteresis. Initially, valve 16 is open, valve 17 is closed. In this case, the filling of the container 5 occurs in the same way as was indicated when describing a variant of the device shown in FIG. 1. However, when water in the tank 5 rises to a predetermined level 1-1, the water pressure is sufficient to open the valve 17. Water flows into the valve chamber and creates pressure in it, acting on the membrane 20. Under the action of this pressure, valve 16 closes

The supply of water to the tank 5 is turned off and on. When the water from tank 5 is consumed, the water level in the latter is reduced to the set value 1J-1T. The pressure in the chamber

the valve is so reduced that under the action of the weight .19 the valve 16 opens and the valve 17 closes. With the opening of the valve 16, the water supply to the tank 5 is switched on again. Levels

the water in the storage unit, in which the water supply is automatically turned on and off, can be set differently: for this purpose, dimensions 0 of the opening of the conduit 22, throttles 21 and other elements of the circuit are appropriately selected.

The proposed device provides a solution to the problem of water lifting at 5 low-pressure water supply without the use of additional energy sources.
