Telescopic anti-freezing device for shallow well

Abstract

The invention relates to the technical field of well lids, and discloses a telescopic anti-freezing device for a shallow well. The telescopic anti-freezing device comprises a water well body, wherein U-shaped limiting blocks are installed on the tops of mounting blocks, a sliding groove is formed in the bottom of a base plate, limiting holes are formed in the surface of the base plate at the sliding groove, telescopic pieces are arranged on the circumferential surface of the base plate, sliding blocks are arranged on one side of the telescopic pieces, clamping pieces are arranged on the other sides of the telescopic pieces, and the clamping pieces are arranged in the U-shaped limiting blocks. According to the telescopic anti-freezing device for the shallow well, the sliding blocks, the sliding groove, the limiting holes, the limiting blocks, the clamping pieces and the U-shaped limiting blocks are formed and arranged, so that the telescopic anti-freezing device has a telescopic adjusting function and a windproof function, the size of a well lid can be conveniently adjusted so as to adapt to shallow wells of different sizes, high practicability is achieved, and additionally, the well lid is effectively prevented from being blown over by strong wind, so that the functionality of the anti-freezing device is increased, and the anti-freezing device is compatible with an existing pasturing area solar water supply system and has practicability.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to a retractable antifreeze device for shallow water source wells. Background technique [0002] In some pastoral areas in northern China, the main source of water supply is shallow water source wells with relatively shallow static water levels. In addition, it is located in an alpine region with long and cold winters. In winter, it is often frozen due to low temperature and lack of reliable and effective antifreeze facilities. It is difficult to exert its water supply function, which has a great impact on the normal production and living water of herdsmen. There are few antifreeze design materials for shallow water source wells in pastoral areas. According to the different antifreeze principles, they are divided into passive and active. To increase the height of the water source well cover, replace the soil around the well cover with materials with poor thermal conductivity suc...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a retractable antifreeze device for shallow water source wells, which has the advantages of telescopic adjustment function and windproof function, and solves the problems caused by different wellhead sizes during the use of existing well covers. There are some deviations, and the existing manhole covers do not have the function of telescopic adjustment, and cannot adapt to manhole covers of different sizes, so the practicability is low. In the well, and there are certain dangers
