Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] Such as figure 1 - The jacking shaft multi-stage fast flushing door shown in 2 includes a pipe foundation 1, a rotating shaft 2 is connected between the pipe foundation 1 on opposite sides, and the rotating shaft 2 is connected with a weir plate 3, and the weir plate 3 is vertically There are at least two pieces in the direction, and the top of each weir plate 3 is provided with a rotating shaft 2, such as figure 2 and Figure 4 As shown, a weir plate gasket 4 that can be compressed and sealed with the rotating shaft 2 is provided between the rotating shaft 2 and the weir plate 3 above it, and the weir plate sealing gasket 4 is fixed on the bottom of the weir plate 3, as shown in figure 2 and Figure 5 As shown, the bottom pipe foundation 1 is fixed with a first limit stopper 5.1, and the first limit stopper 5.1 is fixed with a first...

Abstract

The invention discloses a top shaft multistage rapid flushing gate which comprises pipe culvert foundations. Rotating shafts are connected between the opposite pipe culvert foundations at both sides; the rotating shafts are connected with weir plates; at least two weir plates are provided in the vertical direction; the top of each weir plate is provided with one rotating shaft; weir plate sealing cushions capable of being compressed and sealed with the corresponding rotating shafts are arranged between the corresponding rotating shafts and the weir plates above the rotating shafts; the weir plate sealing cushions are fixed at the bottoms of the weir plates; a first limiting check block is fixedly arranged on the pipe culvert foundation at the bottom; a first limiting sealing cushion capable of being compressed and sealed with the bottommost weir plate is fixedly arranged on the first limiting check block. By a plurality of rotating weir plates, a pressure borne by one single weir plate is reduced, and the size and the intensity requirement of each single weir plate are reduced; each single weir plate bears a small pressure and has a high opening speed; when the plurality of rotating weir plates simultaneously rotate to be opened, a good flushing effect can be formed; by selecting a suitable number of the weir plates to be opened, the aim of regulating the water discharge is fulfilled; the top shaft multistage rapid flushing gate has a simple structure, can be designed to have different sizes according to different environments and is convenient to install and manufacture.

Description

technical field [0001] The invention relates to flushing equipment in a drainage system, in particular to a jacking shaft multi-stage fast flushing door. Background technique [0002] In the drainage system, in order to achieve the purpose of not only controlling the water interception flow, but also controlling the discharge water flow, weir plates are usually used for control. The weir plate is a water-passing structure. When the weir plate is closed and the upstream water level is lower than the top of the weir plate, the water cannot pass through. At this time, the weir plate only has the function of retaining water or intercepting the flow; The intercepted water turns over the top of the weir plate to be discharged; 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 at this time. [0003] In the prior art, the weir plate is mostly an integral weir plate, t...
