Abstract

A device for extracting water from a well comprises a pipe for discharging water from the well inserted into the casing, and a check valve is installed in the pipe, below which there is a hole through which the pipe connects to a channel connected to the compressor and terminates in a damper, and an air outlet is installed in the channel valve.

Description

The proposed device for producing water from a well relates to the field of agriculture and is intended for the production of technical and drinking water from wells.

Known devices for water production, consisting in the intake of water from open reservoirs [1], which contain a water intake connected to a pumping unit connected through a water pipe to a consumer.

However, the disadvantage is that they can only be used for open water bodies, which are not enough, and the number of unsuitable for use from their number is increasing.

A device for producing water from wells using a vacuum [2] is known, which consists of a pump, the suction organ of which is located in the lower part of the well and is tightly connected by the volumetric flowing part (including the lower part of the casing, separated from the upper part by an airtight packer, a strainer and gravel sprinkling the outer part of this filter and the lower part of the casing adjacent to it) with a surface bordering the soil, the pores of which are filled with water, by pumping water from the volume of the flowing part.

However, the disadvantage of this device is that water production is possible only from shallow wells with a very low flow rate and with correspondingly small needs.

The closest analogue selected as a prototype of the claimed device is a device for producing water from wells [3], containing a pump and a pipe for pumping water from the well, installed in the casing.

However, the disadvantage of this prototype is that it is necessary to lower the pump to the place of water collection and drill a larger diameter well, as well as the high cost of these devices for water production.

The technical result of the utility model is to simplify the design of the device, and its maintenance, reducing the cost of the device itself. In addition, the diameter required for drilling the well is reduced.

The technical result is achieved by the fact that a non-return valve is installed in the pipe, below which there is a hole through which the pipe is connected to a channel connected to the compressor and ending with a damper, and an air-discharge valve is installed in the channel.

In FIG. 1 shows a general view of a device for extracting water from a well.

The device comprises a pipe 1 for draining water from the well 2, inserted into the casing 3, a check valve 4, a hole 5, a channel 6, a ventilation valve 7, a compressor 8, a shutter 9 are made below the check valve 4.

A device for extracting water from a well works as follows. The pipe 1 for draining water from the well 2 with the channel 6 connected through the hole 5 is placed in the casing 3. Since there is a certain static water level H in the well 2, when the pipe 1 is placed to drain the water from the well 2, the same water level is established in it H. Channel 6 is connected to the compressor 8 and has a branch with a shutter 9 at the end.

When the compressor 8 is turned on, the shutter 9 closes, air through the channel 6 starts to be pumped into the pipe 1 to drain water from the well 2. The air pressure begins to increase, and the liquid column decreases with an increase in the air column. As soon as the air pressure ceases to increase, the compressor 8 trips relay shutdown (in Fig. Not shown). When the compressor 8 is turned off, the air release valve 7 is released and the shutter 9 opens. The column of water rises upward to the check valve 4 under the action of pressure differences, and collects kinetic energy. Pumped into the pipe 1 to drain water from the well 2, the air is squeezed out of the water through the air valve 7 and exits through the channel 6 through the open damper 9. As soon as all the air leaves the pipe 1 to drain the water from the well 2, the air valve 7 is closed. Given the force of friction of water on the walls of the pipe 1 to drain water from the well 2 and the resistance force of the check valve 4, part of the water rises to a certain height h, the check valve 4 closes and prevents the reverse movement of water. The cycle repeats when the water reaches the collection level.
