Description

Technical Field

[0001] The utility model belongs to the technical field of submersible sewage pumps, and particularly relates to an improved submersible sewage pump. Background Art

[0002] The sewage pump is a pump product that integrates the pump and the motor, which has the characteristics of compact structure, small footprint, easy installation and maintenance, etc. It is usually designed as an open or semi-open structure, which can accommodate sewage with solid particles and is widely used in various fields.

[0003] A Chinese patent with publication number "CN211500980U" discloses a submersible sewage pump, which includes a submersible sewage pump body, a water inlet at the bottom of the submersible sewage pump body passes through a supporting circular plate, the inner cavity of the water inlet is provided with a filter mechanism, the upper plate surface of the supporting circular plate is provided with an annular guardrail, the outer wall of the submersible sewage pump body is fixedly provided with an annular buckle plate, and its inner side wall is fixedly connected to the outer wall side of the annular guardrail by a stabilizing mechanism on both sides, and a plurality of outwardly inclined support rods are fixedly connected to the bottom edge of the supporting circular plate. The utility model provides a submersible sewage pump, which enables the submersible sewage pump to be fixed horizontally and vertically on the ground, ensures that the submersible sewage pump always maintains a vertical state when working, avoids affecting the sewage discharge effect due to the tilting and turning over of the submersible sewage pump, and prevents large volumes of debris from being drawn into the pump body and damaging the pump body, and the filter can be easily disassembled for cleaning to prevent dirt from clogging the filter and affecting the sewage discharge efficiency, and the operation is simple.

[0004] During use, the above-mentioned device can assist in playing a certain anti-blocking function, but when the sewage pump is pumping sewage, impurities in the sewage will inevitably adhere to the outer surface of the filter, thereby affecting its pumping efficiency. In severe cases, it is easy to cause the sewage pump to be in an idling state, which is easy to affect its service life. At the same time, during its use, although a filter quick disassembly and assembly structure is set, it is obviously necessary to take out the sewage pump before it can be disassembled and assembled. If it is taken out, the sewage pump must be stopped before it can be disassembled and assembled. It can be seen that there are certain defects and shortcomings in its overall use process, which need to be improved. Utility Model Content
