A buoy submersible tubular pump device

Abstract

The patent of the present invention relates to a buoy submersible tubular pump device, including a buoy, a submersible tubular pump, a fixed steel frame, and a water delivery hose; the top of the fixed steel frame is connected to the buoy, and the bottom is connected to the submersible tubular pump. The steel frame is fixedly connected to the submersible tubular pump; the outlet of the submersible tubular pump is connected to the water delivery hose, and the connection is seamless and free of water leakage; the shape of the submersible tubular pump is cylindrical, and the length of the submersible tubular pump is l is the average outer diameter of the submersible tubular pump r 10~20 times; the height of the buoy is h , with a length of a , with a width of b ; length of buoy a is the length of the submersible tubular pump l 0.8~1.5 times of buoy width b is the length of the submersible tubular pump l 0.1 times the height of the buoy h Drainage value for buoy k 1.2~1.5 times of , and the height of the buoy h It satisfies the requirement of convenient installation; through the present invention, it can float up and down automatically according to the change of the water surface, and adapt to the pumping condition with large water level drop.

Description

technical field [0001] The patent of the invention relates to a buoy submersible tubular pump device, which belongs to the technical field of pump station engineering. Background technique [0002] At present, the mobile pump house for coastal and inland lakes is usually pontoon type, which has the disadvantages of large volume, easy corrosion, complex structure, and inconvenient disassembly. When pumping water in the floating pump room, generally use a vacuum pump to evacuate the water inlet pipe first, and then pump water; or use a centrifugal pump to pump water, but it needs to be irrigated and exhausted in advance, otherwise it will be unable to work because it cannot absorb water. The water inlet pipeline of the floating pump house is long, and there is no air inside the water inlet pipeline before pumping, so the sealing requirements of the water inlet pipeline are high, and the inlet bottom valve of the water inlet pipeline is required to be free of leakage, otherwise...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a buoy submersible tubular pump device in order to solve the problems of the above-mentioned mobile water intake facilities, which can effectively solve the disadvantages of easy corrosion and poor environmental adaptability of the floating boat type pump room widely used at present, and provide a The simple matching method between the buoy and the submersible tubular pump of the buoyancy submersible tubular pump device has the advantages of fast type selection. The design, processing and manufacturing costs of the device also make the buoy more compatible with the submersible tubular pump device, which has certain significant advantages
