Abstract

The invention provides a drainage device, and relates to the technical field of drainage. The drainage device comprises a main body provided with a water passing cavity inside, a fan blade rotatably arranged on the main body and positioned in the water passing cavity, an upper cover for covering the water passing cavity, and a motor assembly for driving the fan blade to rotate. The main body is provided with a water inlet and a water outlet separately communicating with the water passing cavity; the fan blade is provided with multiple blades; the upper cover is provided with a pressure reliefhole for communicating the water passing cavity with the external; and the pressure relief hole corresponds to the water passing cavity, and is sandwiched in a region between the water inlet and the water outlet. The multiple blades divide the water passing cavity into multiple water passing regions; the fan blade rotatably passes through the multiple water passing regions to carry water from thewater inlet to the water outlet; and the flow speed of the water flowing out from the water outlet is accelerated through a mode of improving the kinetic energy of the water, so that the drainage effect is improved.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a drainage device. Background technique [0002] At present, the drainage system of buildings mostly relies on gravity, and drains water through a combination of sinks and electric pumps. For example: Chinese patent CN201810348865.5 discloses a drainage system for underground garages, which guides the flow through the water guide tank, and the fixed plate at the upper end of the water inlet tank facilitates the insertion of the cover plate into the interior of the storage cavity through the fixed column, and at the same time absorbs the water through the magnet. The cover plate is limited and fixed, which makes the cover plate easy to disassemble; a guide rod is fixedly installed on the fixed plate, and the telescopic movement of the guide rod makes the water baffle play a telescopic and reciprocating role, so that the cleaning brush provided under the water baffle is The debri...
