Urban underground drainage pump with regulation and storage facility

Abstract

The invention relates to an urban underground drainage pump with a regulation and storage facility. The urban underground drainage pump comprises a pump body. A water inlet is formed in the outer surface of the left side of the pump body, a water inlet pipe is fixedly connected to the outer surface of the left side of the water inlet, and a scraping mechanism is arranged inside the water inlet pipe. A water outlet is formed in the outer surface of the upper end of the pump body, and a water outlet pipe is fixedly connected to the outer surface of the upper end of the water outlet. The scraping mechanism comprises a circular plate, a scraping ring plate, first sliding blocks, a winding spring, a rotating piece and a first spring. The first sliding blocks are fixedly connected to the outer surface of the upper end and the outer surface of the lower end of the circular plate. According to the urban underground drainage pump, the inner walls of the water inlet pipe and the water outlet pipe can be cleaned, and therefore the situation that the secondary pollution caused by adhesion objects on the inner walls of pipe bodies to water in the water drainage process cannot happen can be ensured, then the quality of the discharged water is improved, and later use is facilitated; and meanwhile, the drainage pump in the working process can be subjected to vibration reduction, so that the damage to the drainage pump is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of drainage pumps, in particular to an urban underground drainage pump with regulation and storage facilities. 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 of the vacuum area 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] When the existing drainage pump is in use, a large amount of attachments will adhere to the inner wall of the water inlet pipe and the outlet pipe after long-term use, resulting in the water quality when the purified...

AI Technical Summary

Problems solved by technology

[0003] When the existing drainage pump is in use, a large amount of attachments will adhere to the inner wall of the water inlet pipe and the outlet pipe after long-term use, resulting in the water quality when the purified rainwater is discharged, which will be polluted by the attachments in the pipe again, thereby reducing the water quality. The quality of the pipe wall, as well as the internal attachments that are not cleaned for a long time will corrode the pipe wall, resulting in water leakage on the pipe wall and increasing the cost of maintenance and replacement. At the same time, the drainage pump will vibrate when it is working. Fixed, the strength of shaking during work will cause damage to the drainage pump, thus increasing the maintenance cost of the drainage pump;
