Embodiment Construction

[0018] The anti-freezing method of the water well in the permafrost layer of the present invention is: during the period when the water pump stops working, the water level in the water well is pressed below the permafrost layer by using high-pressure gas.

[0019] For convenience and practicality, the high-pressure gas is compressed air.

[0020] Said method can be realized like this: an air compressor is equipped for the water well, and the air supply pipe of the air compressor communicates with the well wall pipe and the water pump outlet pipe of the water well. When the water pump stops working, the compressed air is pressed into the well by switching the water supply and air supply valves. The air supply pressure of the air compressor meets the requirement of pressing the static water level of the well below the permafrost layer, thereby preventing the overall freezing of the well wall pipe, deep well submersible pump and water pump outlet pipe located in the permafrost ar...

Abstract

The invention discloses an anti-freezing method and device of water wells in perennial frozen soil. The anti-freezing method includes the step that while a water pump stops running, water level in a water well is decreased to be below the perennial frozen soil by pressure of high-pressure gas. The anti-freezing device comprises a high-pressure gas source (1). The high-pressure gas source (1) is connected with a water pump outflow pipe (5) through a gas supply pipe; the gas supply pipe is provided with a gas supply valve (2). The anti-freezing device further comprises an exhaust valve (3). An inlet of the exhaust valve (3) is communicated with a well-wall pipe (6) through an exhaust pipe. An outlet of the exhaust valve (3) is communicated with atmosphere. The anti-freezing device further comprises a water supply valve (4) arranged behind a gas supply pipe connection on the water pump outflow pipe (5). The anti-freezing method and device is capable of simply and effectively preventing the water wells in the perennial frozen soil from being frozen.

Description

technical field [0001] The invention belongs to the field of antifreeze technology for water intake devices, in particular to an antifreeze device for water wells which is convenient in construction, low in cost, simple in system, low in operating cost, strong in environmental adaptability, convenient in management, good in antifreeze effect and high in 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 automa...
