Adjustable multi-functional multi-stage weir plate

Abstract

The invention discloses an adjustable multi-functional multi-stage weir plate, which includes a plurality of weir plates installed on a vertical surface, the weir plate includes a plurality of water retaining weir plates and a cleaning weir plate, each water retaining weir plate The bottom is correspondingly connected with a first rotating shaft, and a first sealing structure is provided between the first rotating shaft and the water retaining weir below it, and the top of the cleaning weir is connected with a second rotating shaft, and the second rotating shaft is arranged at the most Below the lower first rotating shaft, a second sealing structure is provided between the second rotating shaft and the lowermost first rotating shaft, and a third sealing structure is provided at the bottom of the cleaning weir plate. The present invention drives the first rotating shaft and the second rotating shaft to turn over through the driving device, and then drives each water retaining weir plate and cleaning weir plate to turn over, and realizes the control of water level and flow through the opening degree of turning over; and the cleaning weir plate at the bottom The rotation axis of the weir plate is set at the top, which can prevent its opening and closing from being affected by the deposition of sediment before and after cleaning the weir plate, and at the same time, it can perform flushing on the bottom of the pipe and channel.

Description

Technical field [0001] The invention relates to flushing equipment in a drainage system, in particular to an adjustable multifunctional multi-stage weir plate. Background technique [0002] In the drainage system, in order to achieve the goal of not only controlling the water interception flow, but also solving the large amount of water discharge, weir plates are usually used for control. The weir is a water-passing structure. When the weir is closed and the upstream water level is lower than the top of the weir, the weir only has the function of blocking water; when the upstream water level exceeds the top of the weir, the interception flow is exceeded The water is discharged through the top of the weir plate; if the upstream water level does not exceed the top of the weir plate and needs to be discharged, open the weir plate and the upstream water level can be discharged. [0003] In the prior art, most of the weir plates are integral weir plates, that is, a weir plate is arrang...

AI Technical Summary

Problems solved by technology

[0004] Such a weir plate setting results in that the drainage of the canal can only be controlled at the maximum flow rate, and the drainage of the irrigation canal cannot be controlled according to external conditions; and when the rotation axis is at the bottom of the canal, various sediments in the water will accumulate at the bottom of the canal, accumulating over time. Reduced water displacement, which can even hinder the operation of the rotating shaft
