Embodiment Construction
[0014] The present invention will be further described in detail below with reference to the drawings and specific embodiments:
[0015] Such as figure 1 The hydraulic downward-opening weir gate shown includes a weir gate frame 1 and a weir gate door plate 2 movably matched with the weir gate frame 1. A groove is opened in the middle of the weir gate frame 1, and two sides of the groove are guide grooves 3 , The two sides of the weir door plate 2 are slidingly fitted with the guide groove 3, and the bottom passes through the weir door frame 1. A hydraulic oil cylinder 4 is arranged in the weir door frame 1, and the piston rod 5 of the hydraulic oil cylinder 4 is connected to the weir door door plate 2. The weir gate door plate 2 is driven to move up and down in the weir gate frame 1 through the hydraulic cylinder 4, the weir gate can be installed in a variety of construction environments without being restricted by circuits, and can be installed below the water surface, with a sim...

The invention discloses a hydraulic downward-opening weir gate, which comprises a weir gate frame and a weir gate door plate which is movably matched with the weir gate frame. The side is a guide groove, the two sides of the weir gate door plate are slidingly matched with the guide groove, the bottom passes through the weir gate frame, and a hydraulic cylinder is installed in the weir gate frame, and the piston rod of the hydraulic cylinder is connected to the weir gate door plate. The present invention has the following advantages: 1. The overall structure is compact, simple and easy to manufacture, the device can be installed underwater, and is suitable for various environments. 2. The weir door panels can be stopped at different heights to control different water distribution flows or adjust different upstream water levels. 3. The hydraulic cylinder can be equipped with an automatic control system to realize unattended automatic control of the hydraulic downward opening weir gate. 4. The structural parts are made of structural steel or stainless steel, which is light in weight, strong and durable, and has high corrosion resistance. 5. It is convenient and simple to replace the sealing strip on the guide groove. 6. The maintenance of the device is simple and convenient.
Description
Technical field [0001] The invention relates to the technical field of water supply and drainage equipment, and in particular to a hydraulic weir gate that opens downwards. Background technique [0002] In my country’s urban water supply and drainage projects, water supply and drainage devices often have a clear division of labor. As the construction of water supply and drainage systems in cities becomes more and more perfect, it can be used for both water supply engineering (water distribution) and drainage engineering (adjusting upstream water level). ) The demand for devices is increasing. A weir gate is a structure in water supply and drainage engineering. The structure is often driven by electricity. Its structure is complex and requires high use environment. Therefore, a weir gate structure with a simple structure and suitable for various environments is required. Summary of the invention [0003] In view of the above technical problems, the present invention provides a hydr...
