Anti-locking floating pump

Abstract

The invention belongs to the technical field of water pumps and particularly relates to an anti-locking floating pump. The anti-locking floating pump comprises a pump body and a floating ring. The floating ring is provided with at least one water inlet and consists of a plurality of split bodies enclosing to form a holding cavity, the pump body is arranged in the holding cavity, the water inlet communicates the outside world with the holding cavity, a filter screen is fixed at the water inlet of the floating ring and comprises a mounting frame and a screen body arranged on the mounting frame,the screen body is provided with a plurality of filter holes, the mounting frame is provided with slide rods, the floating ring is provided with mounting holes, and the slide rods are arranged in themounting holes and can slide along the axes of the mounting holes. The anti-locking floating pump has the advantages that the filter screen move outwards under the action of the thrust of water duringback flush, a preset width spacing is reserved between the periphery of the filter screen and the floating ring, and impurities in the floating ring and on the inner sides of the filter holes can beflushed outside the floating ring conveniently and are prevented from being deposited on the inner sides of the filter holes, so that both the back flush efficiency and the operation efficiency of thewater pump are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to an anti-blocking floating water pump. Background technique [0002] Due to the particularity of emergency drainage and rescue, such as the suddenness of events, the urgency of rescue, the complexity of the working face, the safety of operations, the randomness of the construction environment, the environmental protection of the work site, the arbitrariness of time, the continuous Long working hours and other characteristics, which also put forward higher and more professional requirements for the corresponding equipment. The pump used to solve the problem of drainage is an ordinary pump, which has a large volume and weight, and needs to be used in conjunction with external lifting equipment or heavy transportation tools. It has high energy consumption, small displacement, slow response to disaster relief, heavy movement, and insufficient displacement. Adjustment and other de...

AI Technical Summary

Problems solved by technology

[0003] In the process of emergency drainage and rescue, the water quality is poor, there are many sundries in the water, and the sundries are of different sizes. The phenomenon of clogging the water pump often occurs, which seriously affects the working efficiency of the water pump. In the prior art, when the water pump is used to pump sewage or medium with many impurities , The outer surface of the water pump filter is constantly covered by impurities, resulting in a continuous decrease in the flow rate of the water pump. After running for a period of time, the water pump needs to be lifted up to clean up the impurities before it can work normally. The operation is very troublesome.
