Mobile type submersible pump station for mine emergency rescue and drainage

Abstract

The invention provides a movable type submersible pump station for mining emergency rescue and drainage, and belongs to the technical field of coal mine underground emergency rescue equipment. The movable type submersible pump station comprises a crawler chassis; a submersible electric pump is arranged in the middle of the crawler chassis; a lifting platform is arranged above the submersible electric pump; and a lifting control device is connected with the lifting platform and used for adjusting the height of the lifting platform based on a water level and keeping the lifting platform always above the water surface. According to the movable type submersible pump station, the installation and transportation time of emergency drainage rescue equipment can be shortened, the labor intensity of rescue workers is relieved, and the safety of a rescue site is improved.

Description

technical field [0001] The invention relates to a mobile submersible pump station for mine emergency rescue and drainage, and belongs to the technical field of underground emergency rescue equipment in coal mines. Background technique [0002] There are fixed drainage pump rooms and pumping stations in the underground of coal mines, and supporting drainage pipelines are laid. While the drainage pumps and drainage pipelines meet the needs of the mine's working water inflow and maximum water inflow, there are also backup pumps, maintenance pumps, and backup pumps. Drainage pipes, etc. These devices are fixed facilities. When floods occur in coal mines, especially in the case of local water seepage accidents, these existing drainage systems may no longer work normally, or the drainage system may work, but the displacement can no longer meet the requirements. In the case of safe production in the mine, it is necessary to quickly build a temporary drainage system. Under normal c...

[0002] There are fixed drainage pump rooms and pumping stations in the underground of coal mines, and supporting drainage pipelines are laid. While the drainage pumps and drainage pipelines meet the needs of the mine's working water inflow and maximum water inflow, there are also backup pumps, maintenance pumps, and backup pumps. Drainage pipes, etc. These devices are fixed facilities. When floods occur in coal mines, especially in the case of local water seepage accidents, these existing drainage systems may no longer work normally, or the drainage system may work, but the displacement can no longer meet the requirements. In the case of mine safety production, it is necessary to quickly build a temporary drainage system

Under normal circumstances, underground emergency rescue drainage in mines generally adopts large-flow, high-lift centrifugal pumps or submersible pumps. These heavy and bulky water pumps are inconvenient to move underground, which often affects the speed of mine emergency drainage; especially As the water level drops during the drainage process, the water pump needs to move forward in the muddy roadway to track the water level, which requires people to carry it on their shoulders. The labor intensity of the rescuers is high, and there are certain safety hazards. These become the bottleneck restricting the improvement of emergency drainage efficiency. One, so it is necessary to improve mine rescue emergency drainage equipment
