Description

Technical Field

[0001] The present invention relates to the technical field of submersible pump equipment, and in particular to a system and method for quickly installing and conveniently repairing a submersible pump in a surface water body. Background Art

[0002] In surface water environment management projects, internal live water circulation is often used as one of the important measures to improve and maintain the water environment, that is, a water pump is set in the middle of the lake / river to lift the water, and then it is transported to the far end of the surface water body through a pipeline and released back into the lake / river water body, and then it flows back to the water intake area through the river and lake itself, so that a live water circulation is formed inside the water body between the water intake area and the far end area, realizing "running water does not rot". Live water circulation requires water to be taken from the center of the lake (transported to the lake bay) or at the intersection of the river tributary and the main stream (transported to the starting point of the tributary river), and the water intake pump is set at the riverbed in the center of the lake / river.

[0003] Submersible pump installation methods usually include automatic coupling installation and fixed base installation. The automatic coupling installation uses a coupling device to connect the pump and the pipeline, and requires a new concrete pump pit for installation. It is generally used on the shore and is not suitable for situations where water pumps are installed in lakes / rivers where live water circulates (building a pump pit in the middle of the river and a crane above it affects the normal drainage of the river, and it is not advisable to set up structures such as pump pits and cranes in the middle of the lake). The fixed base has problems with submersible pump installation and difficulties in installation and maintenance due to the inability to drain water after a failure.

[0004] At present, submersible pumps can be installed and repaired by installing a hoist on a boat, but due to the different depths and widths of the river and the weight of the water pump, small boats cannot balance to lift the water pump, and medium and large ships are difficult to navigate in shallow lakes / rivers, and the boats themselves are expensive; water pumps can also be installed and removed by frogmen diving into the water, but the installation and maintenance of underwater water pumps is extremely difficult and the labor costs of special types of work are high. For this reason, it is often the case that the installed water pumps are damaged and have to be shut down due to the difficulty of maintenance. Therefore, there is an urgent need for a system and method for rapid installation and convenient maintenance of submersible pumps in surface waters to solve the problem of difficult installation, maintenance and repair of submersible pumps.
