Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a chassis structure and a vertical sewage pump. Background Art

[0002] Vertical sewage pumps are suitable for the discharge of seriously polluted wastewater from factories and commerce, sewage discharge stations in main residential areas, water distribution systems of urban sewage treatment plants, drainage stations of civil air defense systems, water supply equipment of water plants, sewage discharge from hospitals and hotels, municipal engineering construction sites, supporting equipment of mines, rural biogas pools, farmland irrigation and other industries. They can convey sewage and dirt with particles, and can also be used for clean water and weakly corrosive media.

[0003] Existing vertical sewage pumps, such as a vertical sewage pump disclosed in Chinese patent application CN220581280U, record: the sewage pump is placed in a sewage pool, and then the driving motor is started. The driving motor drives the impeller to rotate in the pump housing through the rotating shaft, so that sewage enters from the liquid inlet pipe and is discharged from the liquid outlet pipe; through the provided filtering mechanism, large pieces of garbage in the sewage are filtered before entering the liquid inlet pipe to avoid clogging of the sewage pump. When leakage occurs between the driving motor and the pump housing, the provided anti-seepage groove can play a role of receiving between the driving motor and the connecting block, so that the leaking liquid will not directly contact the driving motor, and the observation hole can play an observation role, and can also play an effect of discharging the leaking liquid when a large amount of leakage occurs, which can protect the driving motor.

[0004] When the above-mentioned vertical sewage pump is in use, the support rod of the sewage pump is at a fixed height and cannot be adjusted according to the use environment or the height of the pump, resulting in an inappropriate installation position of the sewage pump, affecting the normal operation of the sewage pump. Since the support frame of the sewage pump cannot be adjusted and the support frame cannot be stored, the difficulty and inconvenience of transportation will be increased, which will limit the use scenarios and flexibility of the bracket. When the sewage pump is installed on an uneven ground, the sewage pump cannot be placed stably, causing vibration, noise and other problems during use, and also causing the pump to be installed unstable, posing a safety hazard.
