Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical submersible pumps, in particular to an electromechanical submersible pump for coal mines. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. During the mining process of underground coal mines, large amounts of groundwater are often encountered. In order to facilitate the normal mining of coal mines, this water needs to be pumped out; therefore, submersible pumps are needed.

[0003] However, current coal mine electromechanical submersible pumps are usually directly sunk into water when in use. Coal blocks dropped into the water may press on the submersible pump. Since there is no protective structure, the submersible pump may be damaged by the impact of the dropped coal blocks. To address the above problem, a coal mine electromechanical submersible pump is proposed. Utility Model Content
