Description

A mine underground water supply system

technical field

The utility model relates to a water supply system, in particular to an underground mine water supply system.

Background technique

The existing coal mine underground water supply system is directly supplied by the ground pump room through the feed water pump. After the water pump is turned on, the motor continues to run. However, because the underground water consumption is not continuous and stable, the pipeline pressure often remains high, which leads to motor failure. Overheating and excessive current will seriously affect the service life of the pump motor and the stability of the underground water supply system. To solve these problems, the stability of water supply must be considered to meet the water demand for downhole production, and at the same time reduce problems such as overheating caused by continuous operation of the motor, reduce maintenance and energy consumption, and reduce operating costs, but there are no relevant technical reports in the prior art .

Detailed ways

A mining underground water supply system as shown in Figure 1, comprising a ground reservoir 1, a water suction well 2, a water pump valve 3, a water pump 4, and an underground water supply pipeline 5 connected sequentially, is characterized in that: it also includes a sequentially connected The branch water supply pipe 6, the branch upper gate valve 7, the branch lower gate valve 8, and the pipeline control device 9, the branch water supply pipe 6 is connected to the output pipeline of the suction well 2 and the output pipeline of the water pump 4; the pipeline The control device 9 includes a water pump control unit, a ground reservoir water level control unit, and a gate valve control unit. The pool water level control unit includes a storage pump 10 installed at the ground storage tank 1, a water level controller 11 installed in the ground storage tank 1, and a storage control circuit connecting the storage pump 10 and the water level controller 11.

According to the principle of siphon, the water supply system directly supplies water through the pipeline, and the water outlet of the water suction well 2 and the water outlet of the water pump 4 are connected through the branch water supply pipe 6. The height difference between the ground storage tank 1 and the underground water supply pipeline 5 naturally forms a high water pressure. , to ensure the water demand for downhole production, and at the same time, a water level controller 11 and a water storage pump 10 are installed at the surface water storage tank 1, and the water storage control circuit controls the operation or stop of the water storage pump 10 according to the water level sent by the water level controller 11. Ensure that the water storage level of the ground storage tank 1 is always kept at the normal position; when in use, first open the water pump valve 3, turn on the water pump 4 to supply water to the underground, and after the water supply pressure reaches the rated pressure of the water pump 4, open the branch water supply pipe 6 Branch upper gate valve 7, branch lower gate valve 8, shut off water pump 4, water pump valve 3 at the same time, if there is air in the pipeline of branch water supply pipe 6, block the pipeline water supply, then open water pump valve 3, water pump 4 to reach The water supply pressure is enough. For daily water supply, as long as there is sufficient water storage capacity in the ground storage tank 1, the system can realize uninterrupted water supply without continuous operation of the water pump 4, basically realizing maintenance-free and zero energy consumption.
