Double eccentric bottom shaft multi-stage weir plate

Abstract

The invention discloses a double eccentric bottom shaft multi-stage weir plate, which comprises 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, the bottom of the water retaining weir plate Correspondingly connected with the first rotating shaft, the cleaning weir plate is arranged below the first rotating shaft at the bottom, and the cleaning weir plate is connected with the second rotating shaft, the central axis of the second rotating shaft is in line with the horizontal central axis and vertical direction of the cleaning weir plate. The central axis does not intersect, and the second rotation axis is located above the bottom of the cleaning weir plate; below the second rotation axis, there is an arc-shaped track that matches the running track of the bottom of the cleaning weir plate, and the arc-shaped track can slide with the bottom of the cleaning weir plate connected and separated from each other. The invention can effectively clean the bottom of the river channel, and can also open a suitable number of weir plates according to actual needs, so as to achieve the purpose of adjustable drainage.

Description

technical field [0001] The invention relates to the technical field of drainage systems, in particular to a double eccentric bottom shaft multi-stage weir plate. Background technique [0002] In the drainage system, in order to achieve the purpose of not only controlling the interception flow of water, but also solving the problem of massive discharge of water flow, weir plates are usually used for control. The weir plate is a kind of water-passing structure. When the weir plate is closed and the upstream water level is lower than the top of the weir plate, it will not pass through the water. At this time, the weir plate only has the function of retaining water or intercepting the flow; when the upstream water level exceeds the top of the weir plate, the interception capacity Turn over the top of the weir plate to discharge the water; 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 ...

Problems solved by technology

[0004] The Chinese patent application number is "201120300200.0", and the patent name is "Single Arm Driven Bottom Shaft Type Flap Steel Gate", which discloses the technical scheme of "the bottom shaft is set under the bottom sill of the river, and the bottom shaft is connected to the flap gate". Since the bottom shaft of this technical solution is set under the river, various sediments in the water will accumulate at the bottom of the irrigation canal, which will reduce the drainage over time and even hinder the operation of the rotating shaft, causing the bottom shaft to jam.
