Eccentric water tank type hydraulic self flushing intercepting and accumulating door

Abstract

The invention discloses an eccentric water tank type hydraulic self flushing intercepting and accumulating door, which comprises a door plate, wherein a rotating shaft is arranged at the upper part of the door plate, the two ends of the rotating shaft extend into a base body of a water discharge pipeline, the gravity of the part, positioned under the rotating shaft, of the door plate is greater than the gravity of the part positioned above the rotating shaft, a connecting shaft is arranged at the downstream of the door plate, the two ends of the connecting shaft extend into the base body of the water discharge pipeline, an eccentric water tank is rotationally connected onto the connecting shaft, the bottom of the eccentric water tank is provided with a clamp groove, the clamp groove is arranged parallel to the connecting shaft, and in addition, the clamp groove deviates towards the upper steam of the door plate; the top of the door plate can be clamped in the clamp groove, one end of the eccentric water tank is positioned at the upper stream of the door plate, and in addition, a weight balancing element is fixedly connected onto the side wall of the end; one end, positioned at the upper stream of the door plate, of the eccentric water tank is provided with a water inlet, and one end, positioned at the downstream of the door plate, of the eccentric water tank is provided with a water outlet. The water flow in the water discharge pipeline is used as driving force, the opening and the closing of the intercepting and accumulating door can be realized without other external force effects, the structure is simple, the installation is easy, and meanwhile, the transformation on the existing water discharge pipeline is easy.

Description

technical field [0001] The utility model belongs to the technical field of pipeline dredging, in particular to a drainage pipeline flushing device, in particular to a hydraulic self-flushing blocking storage door. Background technique [0002] Drainage pipes need to be cleaned regularly, especially in the combined drainage pipes where rainwater and sewage are discharged together, it is easy to cause pollutants to accumulate inside the pipes, forming blockages inside the pipes, and causing the sewage inside the pipes to ferment and emit odor. At the same time, since the flow of sewage inside the pipeline is smaller than the design flow, it will inevitably lead to the deposition of debris, which will cause functional loss and environmental problems to the pipeline itself and public waters. For this reason, some simple and economical methods need to be adopted to regularly clean the pipes to ensure the smoothness of the drainage pipes. Existing pipe cleaning devices are genera...

AI Technical Summary

Problems solved by technology

Existing pipe cleaning devices are generally scraping tools for pipe wall dirt or cleaning equipment with complex structures

Not only manual operation is required, but some equipment costs are high

There is also a drive device used as a drain pipe flushing gate for opening the gate. The opening and closing of the gate by the drive device will inevitably increase the cost of equipment, and at the same time it is necessary to add a set of devices for monitoring the internal flow of the drain pipe, which further improves the performance of the gate. cost and are more difficult to maintain
