The invention relates to devices and mechanisms for exploitation of groundwater sources and intakes, in particular for pumping artesians the s from the well, containing the discharge pipe and the pump with the transmission shaft (Shabalin, A. F. Operation of industrial pipelines. Ed. "Metallurgy", 1972, S. 143).

However, the presence of the gear transmission in the known devices leads to a large volume loss, reduced feed pressure and efficiency of the pump.

Closest to the proposed to the technical essence and the achieved effect is a device for supplying water from the well containing the pump, the pressure line and the device hydroplane in the composition of the housing and the inflatable chamber, the cavity of which is connected with the pressure pipe through the drain (SU auth. St. N 1044741, class E 03 B 3/08, 1983).

In the known device the available devices hydroplane allows to increase the production of the well. However, during operation of the device in the cavity of the inflatable chamber there are deposits of fine sand (the "pestovania" wells) and dirt falling into the well during installation and maintenance works, and in the cavity of the inflatable chamber is at the next turning on the pump. This can lead to what is generated when you turn off the pump the gap between the walls adfilternone the device from the well.

An object of the invention is the elimination of the possibility of contamination of the cavity of the inflatable chamber devices hydroplane.

This task is solved in that known device has a second drain, the case of the adaptation of hydroplane made in the form of lower and upper limits, and in the cavity of the inflatable chamber with nephalem posted hose of rubberized material, with one end through the lower limiter is connected to the first drain, the other through the top qualifier from the second drain.

In Fig. 1 shows the device when installed in the borehole of Fig. 2 - the device is in working condition.

The device is located in the casing pipe 1 artesian well and contains a pump 2, section 3 the discharge pipe 4, on which is mounted the device hydroplane comprising an inflatable chamber 5, provided with a nipple 6, and the body in the form of lower and upper limits of 7 and 8. In the cavity of the inflatable chamber hose 9 of rubberized material, one end of which is connected to the first drain 10, the other with the second drain 11.

The device operates as follows. Before installing the device on which achene P0where the walls of the chamber 5 reaches the generatrix of the cylinder, is conventionally formed by upper and lower limiters 10 and 11. When this is placed in the cavity of the chamber 5 hose 9 of rubberized material (such as canvas) under the action of high pressure P0is compressed to a minimum volume (Fig. 1).

One end of the hose 9 is connected to the first drain 10, the other with the second drain 11. Therefore, after you install the device in the hole and turn on the pump volume 2 hose 9 under the action of the water entering the drainage system 10 under a pressure equal to the pressure in section 3 the discharge pipe 4, reaches the maximum value. Extending the hose 9 increases the pressure P0in the cavity of the inflatable chamber 5 to a value of Px, under which the walls of the chamber 5 will cover the gap with casing pipe 1 (Fig. 2).

After a moment of overlap of the specified gap further the balance between the volume of pumped water and the volume of water flowing into the casing 1 from the aquifer will occur under reduced compared with the atmospheric pressure on the surface of the water in the well. This causes an additional inflow of water, i.e., increases flow rate route 4 under the action of pressure Pxin the inflatable chamber 5 volume hose 9 begins to decrease and reaches a minimum value when reaching the Pxthe original values of P0at which excludes the presence of water in the hose 9 after recovery in the well static water level. If stop devices are not connected with his dismantling of the casing 1, the sand deposited in the drainage systems 10 and 11 after turning off the pump 2, washed away the next time it is turned off.

Thus, the advantage of the proposed device is that due to the presence of the second drain 11 in the process of pumping water from wells in the hose 9 is continuously updated water. This helps to wash away dirt trapped in the hose 9 when turning on the electric pump 2, and also completely eliminates the deposition in the cavity of the sand.
