Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a hydraulically rotatable weir gate well. Background Technology

[0002] Existing river overflow outlets are mostly open, lacking interception devices. To prevent combined sewage from polluting the rivers, many existing overflow outlets have been blocked, preventing the rapid drainage of upstream water during the flood season. Under high water levels, low-lying areas in cities are more prone to flooding, leading to severe waterlogging and exacerbating the risk of urban flooding. This also overloads other parts of the drainage system, such as drainage pipes, affecting the efficiency of the entire system and impacting residents' travel and daily lives. Furthermore, flooding can damage power and communication lines, further impacting the operation of urban infrastructure. When dealing with overflow outlets, various factors should be comprehensively considered to select an appropriate solution. Therefore, we propose a hydraulically rotating weir gate well to ensure the stable operation of the water conservancy project. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulically rotatable weir gate well to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulically rotatable weir gate well, comprising a weir gate well, an inner plate fixedly connected to the center of the inner wall of the weir gate well, the inner plate being H-shaped, a rotating shaft rotatably connected to the upper half of the inner plate, an upper gate plate provided on the outer wall of the rotating shaft, a pin seat fixedly connected to the left side of the upper surface of the upper gate plate, and a pin hinged at the center of the pin seat, a concave frame fixedly connected to the upper surface of the inner wall of the weir gate well, an outer block provided on the inner wall of the concave frame, pins provided on both sides of the outer block, and the pins of the outer block being hinged to the inner wall of the concave frame, and the end of a first hydraulic cylinder fixedly connected to the pin seat.

[0005] Preferably, the lower half of the inner plate is provided with a bottom door panel, the outer wall of the bottom door panel is fitted with the inner wall of the inner plate, a frame is fixedly connected to the side wall of the bottom door panel, a hydraulic cylinder support is fixedly connected to the outer wall of the weir gate well, a second hydraulic cylinder is fixedly connected to the center of the inner cavity of the hydraulic cylinder support, the piston rod of the second hydraulic cylinder penetrates the side wall of the weir gate well, and the piston rod of the second hydraulic cylinder is fixedly connected to the side wall of the frame.

[0006] Preferably, a reinforcing rod is fixedly connected to the side wall of the frame near the bottom, and the other end of the reinforcing rod is fixedly connected to the piston rod of the second hydraulic cylinder.

[0008] Preferably, a second rubber strip is glued to the outer wall of the bottom door panel, and the outer wall of the second rubber strip is attached to the lower half of the inner wall of the inner panel.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: Driven by hydraulics, the opening angle of the upper door can be flexibly adjusted according to actual needs, thereby controlling the water flow. Normally, the upper door is closed to eliminate pollution of downstream river channels by combined sewage; during the flood season, the upper door is opened, allowing upstream road floodwater to be quickly discharged into the urban drainage system through the overflow outlet. This rapid response and adjustment of the opening angle increases flood discharge capacity, effectively relieving pressure on river channels and urban drainage systems, preventing flooding. By regulating water flow, the ecological flow process of natural rivers can be simulated, creating a suitable living environment for aquatic organisms and promoting the restoration and balance of aquatic ecosystems. Furthermore, it effectively reduces the scouring of the riverbed, protecting the natural morphology and biodiversity of the river. Attached Figure Description
