Sewage pump

The utility model provides a sewage pump, which relates to the technical field of water pumps and comprises a pump body, a water inlet is arranged on the right lower side of the pump body, a water outlet is arranged on the left upper side of the pump body, and a controller is arranged on the left side of the pump body. The blocking assembly is installed, the baffle is arranged to be in a splayed shape through the spring, when sewage passes through the interior of the blocking assembly, the baffle is pressed upwards to be opened and closed, when the baffle is not subjected to pressure, the baffle is closed through the rebound effect of the spring, impurity backflow is prevented, and meanwhile the blocking assembly is attached to the inner wall of the pump body; and the blade is prevented from generating a gap to the shielding assembly. 本实用新型提供了一种污水泵，涉及水泵技术领域，包括泵体，泵体的右下方开设有进水口，泵体的左上方开设有出水口，其中泵体的左侧安装有控制器；通过安装有遮挡组件，挡板通过弹簧设置为"八"字形，而当污水从遮挡组件内部经过时对挡板向上施压，使挡板开合，挡板未受到压力时通过弹簧反弹作用使挡板闭合，防止杂质回流，同时遮挡组件与泵体内壁相贴，进而防止刀片对遮挡组件出现
