Description

Technical Field

[0001] The utility model relates to the technical field of mine shaft and tunnel waterproofing and drainage, in particular to a mine shaft and tunnel waterproofing and drainage device. Background Art

[0002] In underground coal mining, shafts, tunnels and chambers excavated for the needs of lifting, transportation, ventilation, drainage, power supply, etc. are collectively called mine shafts. At present, submersible pumps are mostly used to drain mine shafts, but due to the large amount of impurities under the mine, some impurities or debris will penetrate into the submersible pump when the submersible pump is used for drainage. After long-term use, the submersible pump will malfunction due to the infiltration of debris or impurities, making it impossible for the mine shaft to carry out continuous drainage work.

[0003] A Chinese patent with announcement number CN208816182U discloses a mine well drainage waterproofing device, which plays a filtering role by setting a filter to prevent the water pipe from being blocked by silt, thereby improving the working efficiency of the water pump. By setting a fixing ring and a clamp, the removal and installation of the filter and the connecting pipe are facilitated, the speed of replacing the filter is accelerated, and manpower and material resources are saved.

[0004] However, after the filter cylinder is used for a long time, a layer of debris will adhere to the outer wall of the filter cylinder, which will clog the mesh of the filter cylinder, causing the submersible pump to discharge too little water per unit time, thereby extending the time for draining the well. To this end, we provide a mine shaft waterproof drainage device to solve the above problems. Utility Model Content
