Embodiment Construction

[0019] The basic principle of the antifreeze deep-water well of the present invention is: during the stoppage of the pumping device, the water level in the well is pressed below the permafrost layer by using high-pressure gas.

[0020] In order to reduce cost and use conveniently, the high-pressure gas is compressed air.

[0021] The above principles can be used in conjunction with deep well pumps or with gas extraction water devices. The implementation method of using with deep well pump is as follows:

[0022] like figure 1 As shown, the antifreeze deep-water well of the present invention realizes scheme one, comprises the borehole wall pipe 6 that passes through the permafrost layer 9 down to the aquifer, the deep well pump 7 placed in the borehole wall pipe 6, and the deep well pump 7 The water supply valve 4 communicated with the outlet of the deep well pump 7 also includes an air supply valve 2 communicated with the outlet of the deep well pump 7, and the other end of ...

Abstract

The invention discloses an anti-freeze deep well which comprises a casing pipe (6) which downwards penetrates through a perennial frozen earth layer (9) and reaches a water-bearing layer, a water pumping device (7) arranged in the casing pipe (6), a water supply valve (4) communicated with an outlet of the water pumping device (7) and an air supply valve (2) communicated with the outlet of the water pumping device (7), and the other end of the air supply valve (2) is communicated with a high pressure air source (1). By means of the anti-freeze deep well, freeze of the anti-freeze deep well in the perennial frozen earth layer can be easily and effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of antifreeze water intake devices, in particular to an antifreeze deep water well with good antifreeze effect and high reliability. Background technique [0002] With the development of western my country and the needs of frontier defense construction, in some areas with high altitude, severe winter climate and harsh environmental conditions, it is necessary to open water supply wells. Some source wells need to go through permafrost (permafrost) to extract water from the aquifer below the permafrost. Most of these wells are pressurized wells, and the dynamic and static water levels of the wells will rise to the range of permafrost. When the water supply of the water pump in the well exceeds the user's water demand, the water pump will automatically stop working in order to save water resources and reduce energy consumption. When the pump stops for a long time, due to the continuous loss of heat from the w...
