Self-unblocking sewage pump based on flexible pump body

Abstract

The invention provides a self-unblocking sewage pump based on a flexible pump body, and relates to the field of water pumps. The self-unblocking type sewage pump based on the flexible pump body comprises a frame, the frame comprises connecting sections arranged on the left side and the right side, a flexible pipe is arranged on the inner side of the frame, a sliding frame is fixedly connected to the middle of the flexible pipe, the sliding frame is arranged in the length direction of angle steel in a sliding mode, and a flexible film is fixedly connected to the inner wall of the sliding frame. An arc-shaped rod is arranged on one side of the flexible film, one end of the arc-shaped rod is rotationally connected with the interior of the sliding frame, the other ends of the multiple arc-shaped rods are attached to one another, one connecting section is fixedly connected with an L-shaped water drawing pipe, and a telescopic pipe is connected with the interior of the other end of the water drawing pipe in a sleeved mode; a baffle is rotationally arranged in the lower end of the telescopic pipe. An impeller is omitted, a reciprocating pushing mechanism is adopted, liquid pumping is achieved, and the problem that a traditional pump is prone to being blocked and damaged is solved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a self-cleaning and blocking type sewage pump based on a flexible pump body. Background technique [0002] A water pump is a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid energy, and is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. [0003] When a common pump is working, a high-speed rotating impeller is used to push the liquid to achieve pumping. Sewage pumps are no exception. The sewage contains fibrous materials, gravel and other debris that are easily entangled or bunched. Therefore, the flow channel of this kind of pump is easy to be blocked or wrapped around the impeller. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor ...
