Description

one

The invention relates to water supply mainly from underground sources and can be used in agricultural water supply and watering systems, as well as in land reclamation construction and drainage of peat deposits.

The purpose of the invention is to increase productivity and reduce energy consumption.

FIG. schematically shows the proposed device for groundwater abstraction, general view; Fig. 2 is a block diagram of the control of the operation of the slide mechanism and the pump.

The device for groundwater intake consists of a tank I, hermetically sealed from above, a bottom filter 2 with backfill 3, a pump 4 for pumping water with suction 5 and discharge 6 pipelines, a filling tank 7 with a discharge pipe 8 and sensors 9 and 10 of the upper and lower levels water in the tank. The level sensors are connected to the pump through the program block 11. A spool-mounted mechanism 12 is installed on the upper floor of the tank, communicating via a tube .13 with the cavity of the tank, and the control input is via an electromagnet 14 connected to the program block 11. open and close the spool mechanism (figure 2).

The device works as follows.

2148602

The tank 1, hermetically sealed from above, located in a shaky well, through the filter 2 and backfill 3, continuously receives water from their water bearing layer. The pump 4, through the suction pipe 5, pumps the water out of the tank and, under pressure, supplies it via the discharge pipe 6 to the bulk tank 7, from which water

 O through the diverting conduit 8 is directed consumer. As a result of pumping water from the reservoir and lowering the level, a vacuum (vacuum) is created in the free cavity of the reservoir, the value of which increases with decreasing water level.

The upper and lower water levels are monitored by sensors 9 and 10, the signals from which are fed to the software.

20 block 1 for controlling the operation of the pump 4 "After a certain period of time, controlled by time controllers 15, software block 11 with electromagnet 14 acts on the gold mechanism 12, moves its piston, communicating through the tube 13 the cavity of the tank with the atmosphere. The removal of vacuum allows the continuity of the capillary-filtered moisture to be maintained.

30 by preventing the vacuum from collapsing as a result of air bubbles entering the capillaries and increasing the filtration rate by 1.5–3.0 times. The filtration rate increases due to the fact that when the vacuum is removed, air bubbles pop up on large pores, improving pressure transfer. by eliminating the energy expended in compressing the bubbles.
