Description

Technical Field

[0001] The present invention relates to the technical field of sewage lifting, and in particular to an integrated sewage lifting device. Background Art

[0002] Integrated sewage lifting equipment is mainly used for lifting and discharging waste water discharged from sewage pipes and sanitary facilities that are below the sewer liquid level or far away from the municipal sewage network. That is, waste water discharged from sewage pipes and sanitary facilities that are below the sewer liquid level or far away from the municipal sewage network is collected through a collecting tank, and the waste water is lifted and pumped into the urban sewage system.

[0003] For example, the Chinese patent "CN111441323B integrated sewage lifting equipment" published on September 15, 2020, has a float that is a hollow rectangular body on the bottom, and the bottom plate is fixedly connected to the bottom of the float. Both sides of the top surface of the bottom plate are hollow. There are two lifting devices, which are respectively sleeved on the inner walls on both sides of the bottom plate. Through the setting of the lifting device, the sewage collecting bottle is used to dig out the rain and sewage on the surface of the water area, and it is separated from the water surface tension and accumulated on the inner wall of the recessed bottom of the sewage collecting bottle, thereby realizing the collection and separation of rain and sewage on the surface of the water area. Then, the flow of water is used as the power to drive the two sewage collecting plates to move in an opening and closing trajectory, which has a compression effect on the accumulated rain and sewage in the sewage collecting bottle, reduces the volume of rain and sewage to increase the storage capacity of the sewage collecting bottle, and increases the density of rain and sewage, thereby avoiding the possibility of rain and sewage being washed away by water, and using the sewage collecting plate to accommodate part of the rain and sewage, further increasing the collection space of the sewage collecting bottle for rain and sewage.

[0004] During the application process, the existing integrated sewage lifting equipment is mostly driven by a single motor. Affected by the motor's own factors, it needs to stop and dissipate heat after each continuous operation for a certain period of time to avoid overheating of the motor and affecting its life. During this process, sewage lifting operations cannot be carried out, which greatly affects the sewage discharge efficiency. Summary of the invention

[0005] The present invention relates to an integrated sewage lifting equipment, which solves the problem that the existing integrated sewage lifting equipment is mostly driven by a single motor during application.

[0018] In addition, the small spring has an elastic reset effect on the movable switching frame. By rotating the rotating hand lever, the inclined block contacts the inclined surface and is subjected to force. The rotating hand lever drives the movable switching frame to move in the opposite direction of the lifting pump. The small spring is subjected to force and is in a contracted state.
