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 arranged on a vertical surface, wherein the weir plates comprise a plurality of water blocking weir plates and one cleaning weir plate, the bottoms of the water blocking weir plates are correspondingly connected with first rotating shafts, the cleaning weir plate is arranged under the lowest first rotating shaft, the cleaning weir plate is connected with a second rotating shaft, the center axial line of the second rotating shaft is not crossed with the horizontal center axial line and the vertical center axial line of the cleaning weir plate, the second rotating shaft is positioned above the bottom of the cleaning weir plate, an arc-shaped rail matched with the operation track of the bottom of the cleaning weir plate is arranged under the second rotating shaft, and the arc-shaped rail can be glidingly connected with the bottom of the cleaning weir plate and can be mutually separated from the bottom of the cleaning weir plate. The double-eccentric-bottom-shaft multi-stage weir plate can be used for effectively cleaning the bottom of a riverway, the proper number of weir plates can also be opened according to the actual requirements, and the goal of adjustable water discharge quantity can be reached.

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.
