Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding of the present invention, but they do not limit the present invention.

[0015] Such as figure 1 As shown, a top-opening weir gate includes a fixed frame 1, which is in the shape of a hollow box with an open top surface and a closed bottom surface. The fixed frame 1 is provided with a water passage 1-1, The water channel 1-1 is located in the middle of the fixed frame 1 horizontally, and extends longitudinally from the middle and upper part of the fixed frame 1 to the bottom of the fixed frame 1. The fixed frame 1 is symmetrically provided with vertically arranged guide grooves 2, two Two guide grooves 2 are respectively fixed on the two ends of the fixed frame 1; said guide groove 2 is embedded with an opening and closing door panel 3, and the opening and closing door panel 3 can move up and down along the guide groove 2, a...

Abstract

The invention discloses an upper opening type weir gate. The upward opening type weir gate comprises a fixed framework. A water passing channel is formed in the fixed framework, and guide grooves are symmetrically formed inside the fixed framework. An opening and closing gate plate is inlaid in the guide grooves and located on the water passing channel. Opening and closing oil cylinders are symmetrically arranged at the two ends of the bottom of the fixed framework, and piston rods of the opening and closing oil cylinders are connected with the opening and closing gate plate. The opening and closing gate plate is driven by the opening and closing oil cylinders to ascend or descend, the two ends of the opening and closing gate plate slide in the guide grooves upwards and downwards, and the opening and closing gate plate can ascend or descend as needed and can stop at any height position to control different distributed water flows or upstream water levels through interception. The opening and closing oil cylinders can be provided with an automatic control system so that the upward opening type weir gate can be automatically controlled in an unattended mode. Besides, the upward opening type weir gate is easy and convenient to maintain and compact in structure and will not affect a ground landscape.

Description

technical field [0001] The invention relates to water supply and drainage equipment, in particular to an upward opening weir gate. Background technique [0002] In my country's urban water supply and drainage projects, water supply devices and drainage devices often have a clear division of labor. The water supply device is used in the water supply field, and the drainage device is used in the drainage field. The two cannot be mixed. With the construction of water supply and drainage systems becoming more and more perfect, the demand for devices that can be used for both water supply and drainage projects is increasing. [0003] Due to structural limitations, the existing weir gate devices are either only suitable for intercepting the upstream water level, or only suitable for controlling the water distribution flow, and it is difficult to take into account both interception and water distribution functions. Contents of the invention [0004] The object of the present inv...
