Coal mine static pressure water supplying device capable of automatically and rotatably replenishing water

Abstract

The invention discloses a coal mine static pressure water supplying device capable of automatically and rotatably replenishing water. The problems that cost input is high, and requirements of safe andeconomic water supplying of a coal mine can not met in the prior art are solved. The coal mine static pressure water supplying device comprises a coal mine ground static pressure pool, and a pipelinefor supplying water to the underground coal mine is installed on coal mine ground static pressure pool. The coal mine static pressure water supplying device is characterized in that a first deep wellwater pump is installed in a first water well, a first deep well water pump water replenishing pipeline is connected above the first deep well water pump, and the first deep well water pump water replenishing pipeline communicates with the coal mine ground static pressure pool; and a second deep well water pump is installed in a second water well, a second deep well water pump water replenishingpipeline is connected above the second deep well water pump, and the second deep well water pump water replenishing pipeline communicates with the coal mine ground static pressure pool. The coal minestatic pressure water supplying device is reasonable in design, compact in structure, can realize automatic rotation working and alternate automatic water replenishing of a water replenishing pump ofthe coal mine ground static pressure pool, and can automatically monitor high and low water levels of the coal mine static pressure pool, safe and reliable in using, and saving in management cost.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for coal mine mining, and in particular relates to a static pressure water supply device for coal mines which can automatically control the water level and has the function of automatically rotating and replenishing water by water pumps. Background technique [0002] Underground coal mines need a lot of water for dust prevention, cooling and fire fighting. The usual practice is to build a reinforced concrete static pressure pool near the surface wellhead, and introduce it to the underground water point of the coal mine by the pipeline. The ground static pressure pool depends on the deep well water pump to replenish water and always maintain a certain water level; if the water level is too low, it will cause water shortage in the well and affect the normal production in the well; if the water level is too high, it will cause water supply to overflow, resulting in the loss of water resou...

AI Technical Summary

Problems solved by technology

These control methods have great disadvantages: First, the static pressure pool relies on human factors to start the pump to replenish water, which often causes insufficient water level and water overflow, which affects the underground water supply of coal mines or causes waste of water resources

The second is that the manual operation of the pump is arbitrary. It not only requires a dedicated person to work full-time, but also causes a water pump to be turned on for a long time to supply water, resulting in inconsistent wear and tear of the equipment, and once the water pump that has not been used for a long time works in an emergency, it often causes failures.
