Description

Technical Field

[0001] The utility model relates to the technical field of mine drainage, in particular to mine drainage equipment. Background Art

[0002] When the amount of water gushing underground suddenly increases and the operating personnel fail to discover it in time, the amount of water accumulated underground will increase significantly, and in severe cases it may even cause a safety accident. Although a few coal mines use automatic drainage devices for drainage, due to factors such as incomplete control functions, high system failure rate and low reliability, on-site applications still require special personnel to conduct inspections, and the automation function cannot be efficiently utilized. Therefore, a mine drainage equipment is provided to improve the automation level of the drainage system and realize remote control of the start and stop of the water pump.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN219888278U, which discloses an automatic drainage device for underground coal mines. The utility model includes a drainage pump, a connector, a power cord, a chassis, and an auxiliary drainage pipe. The connector is arranged at the top of the drainage pump. When the utility model performs drainage work underground in coal mines, the drainage pump is first operated by the driving cooperation of the power cord, wherein the auxiliary rod seat inside the drainage pump is connected to the power cord, and the auxiliary rod seat will generate a back suction force to suck the waste water outside the drainage pump into the pump body, and flow along the water channel inside the pump body to the outlet, and then cooperate with the auxiliary drainage pipe to discharge the waste water. If mud and sand accumulate and blockage occurs, the sand cleaning device under the pump body will clean and push away the mud and sand to avoid blockage at the water inlet under the pump body, thereby solving the problem that the drainage equipment is blocked and cannot be used.

[0004] Although the existing automatic drainage equipment in underground coal mines solves the problem of reduced pressure in the pressure pipe and the water reducer liquid level reaching the warning level, the drainage pump is only used for drainage, which reduces the practicality of the drainage structure and reduces work efficiency. At the same time, the drainage pump will produce certain vibrations during operation, affecting the drainage work. At the same time, it is not convenient to monitor the flow and temperature during the drainage process, which reduces the use function of the mine drainage equipment. Utility Model Content
