Urban underground drainage pump with sewage intercepting function

Abstract

The invention belongs to the technical field of drainage pumps, and particularly relates to an urban underground drainage pump with a sewage intercepting function. The urban underground drainage pump is used for solving the problems that an existing drainage pump does not have a sewage intercepting function, the interior of a pump body is prone to being blocked and damaged, the cooling effect is poor, and parts are prone to being damaged due to temperature rise in the pump body. The urban underground drainage pump comprises a pump body, wherein the pump body is installed at the top of a bearing seat, a containing chamber and a water inlet chamber are formed in the pump body, a rotating shaft is vertically arranged and rotatably connected with the pump body, the output end of a driving mechanism is connected with the rotating shaft, an impeller is installed on the rotating shaft and located in the water inlet chamber, a drainage pipe is installed on the pump body and communicated with the water inlet chamber, and an anti-shock assembly is mounted between the bearing seat and a fixing seat. The urban underground drainage pump has a sewage intercepting function and is good in sewage intercepting effect, so that the interior of the pump body can be effectively prevented from being blocked and damaged; and the pump body is cooled directly through a discharged water solution, so that the cooling operation can be continuously performed in the use process of the drainage pump.

Description

technical field [0001] The invention relates to the technical field of drainage pumps, in particular to an urban underground drainage pump with the function of intercepting sewage. Background technique [0002] The drainage pump is mainly used to discharge the liquid in the pond or large liquid storage tank. During the working process of the drainage pump, the rotating water flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, the impeller The central part forms a vacuum area, and the water from the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure, so that the circulation is endless and continuous drainage can be realized; [0003] In the Chinese utility model patent application number 2015203398468, a drainage pump is disclosed, which includes a motor and a pump body. The pump body includes a casing and a rotating shaft axially fixed in the casing. T...

Problems solved by technology

[0005] The purpose of the present invention is to provide an urban underground drainage pump with the function of intercepting sewage, which intercepts sundries and floating objects in the sewage through the sewage intercepting grille, and filters and removes impurities in the sewage by the filter bucket to realize sewage interception The purpose is to effectively avoid blockage and damage inside the pump body. The outer peripheral surface of the filter barrel is cleaned by rotating the filter barrel and the cleaning brush, which helps to prevent the filter holes of the filter barrel from being blocked and ensures the effect of intercepting dirt. The discharged aqueous solution dissipates heat and cools down the pump body, which can continuously perform heat dissipation and cooling operations during the use of the drainage pump, which significantly improves the heat dissipation effect and efficiency of the pump body. By setting up anti-seismic components, it helps to improve the performance of the drainage pump. The stability of the use process also helps to reduce the noise caused by vibration. By setting the positioning component, it is convenient to fix and move the drainage pump, which solves the problem that the existing drainage pump does not have the function of intercepting sewage, which may easily cause blockage and damage inside the pump body. , and the heat dissipation effect is poor, it is difficult to quickly dissipate the heat generated by the pump body, and it is easy to cause damage to the components due to the increase in the internal temperature of the pump body
