Embodiment Construction

[0015] The design concept of the present invention is to provide an antifreeze device for tube wells in deep frozen soil and extremely cold regions. The solution is to solve the problem of freezing as long as the water in the pumping pipe in the frozen soil layer is drained after the water pump is out of service.

[0016] Such as figure 1 As shown, it includes air compressor 1, air pressure tank 2, water tank 3, air injection pipe 4, check valve 5, isolation valve 6, shut-off valve 7, tube well 8, water pipe 9, submersible pump 10, air supply pipe 11, discharge water hole 12.

[0017] The connection relationship of each part is as follows: the air compressor 1 is connected to the inlet of the air pressure tank 2 through the air supply pipe 11, the check valve 5 and the isolation valve 6 are sequentially arranged between the end of the gas injection pipe 4 and the water lifting pipe 9, and the air pressure tank 2. The outlet communicates with the part near the end of the water...

Abstract

The invention provides a pipe well freeze protection device for extremely cold regions with deep frozen soil. The pipe well freeze protection device comprises air compressors, a gas pressure tank, a water tank, a gas injection pipe, a shutoff valve, a pipe well, a lifting pipe, a submersible pump and a gas supplementing pipe. The air compressors are connected with an inlet of the gas pressure tankby the gas supplementing pipe, an outlet of the gas pressure tank is communicated with portions adjacent to the tail end of the lifting pipe via the gas injection pipe, and the shutoff valve is arranged at a joint of the lifting pipe and the water tank; a start end of the lifting pipe extends into the pipe well and is connected with the submersible pump. The pipe well freeze protection device hasthe advantages that the gas pressures of pipelines can be maintained by the gas pressure tank of the pipe well freeze protection device which is a gas injection freeze protection device, systems aresimple and stable and are low in energy consumption, and the reliability of the freeze protection systems can be improved; the pipe well freeze protection device is wide in application range, and thelifting pipe can be prevented from freezing no matter how the external temperatures change.

Description

technical field [0001] The invention relates to a tube well water intake system in a deep frozen soil and extremely cold area, in particular to a tube well antifreeze device in a deep frozen soil and extremely cold area. Background technique [0002] In high-altitude deep permafrost and extremely cold regions, the depth of permafrost reaches 40-150m, the depth of tube wells for water intake is about 100-200m, and the static water level is about 10-20m. For tube wells whose static water level is higher than that of the permafrost, when the well pump is in intermittent operation mode, after the well pump is stopped, the water in the pumping pipe cannot be drained, resulting in the well above the permafrost line in the pumping pipe The water was frozen so that the well pump could not start pumping water properly again. The static water level of the groundwater in the tube well in different areas is about a few meters to tens of meters below the ground. When the static water le...
