Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment, specifically a hydraulic rotating weir gate. Background Technology

[0002] A weir gate is a gate installed at the mouth of a weir to adjust the height of the weir. It is mainly used to control and regulate water levels, but can also be used for water distribution and drainage.

[0003] Traditional weir gate driving methods mostly rely on manual operation or motor drive. Under high flow and high water level conditions, insufficient driving force often leads to lag in adjustment, making it difficult to accurately control water level changes. In addition, the mechanical transmission structure is complex and prone to jamming due to siltation and water corrosion, resulting in high maintenance frequency and cost. To address these issues, we propose a hydraulic rotating weir gate. Utility Model Content

[0015] According to one embodiment of the present invention, in conjunction with the appendix Figures 1-4 As shown.

[0016] A hydraulic rotating weir gate includes two mounting supports 1. Rotating components 3 are connected to the adjacent sides of each mounting support 1. Each set of rotating components 3 includes a fixing rod 301, a bearing 302, a cylinder base 303, a rotating assembly 304, a pin 305, a cylinder push rod 306, and two pin holes 307. A gate panel 4 is connected to the outer surface of both sets of rotating components 3. Two sets of fixing components 2 are connected to the outer surface of the gate panel 4. Each set of fixing components 2 includes two support plates 201, a pin 204, a rotating support 202, and multiple fixing holes 203. The bottom of the mounting support 1 is provided with an anti-slip pad with a thickness of 5-8 mm and a diamond-shaped anti-slip texture on its lower surface. The fixing rod 301 is 80-120 cm long, and its outer surface is coated with a coating with a thickness of 0.1-0.3 mm. The zinc coating of the door panel 4 is 10-15mm thick, and the edges of the door panel 4 are rounded. Through the cooperation of the rotating component 3 and the fixed component 2, it can effectively and quickly respond to the working conditions and accurately adjust the opening angle of the door panel 4 to achieve fine control of water level and flow. This effectively solves the problems of adjustment lag and insufficient accuracy under the traditional drive method, improves the adaptability of the equipment under different water level and flow conditions, and enhances the flexibility of engineering applications. Through the sealing rubber strip on the outer surface of the door panel 4, it can effectively fit tightly with the corresponding hydraulic structure, significantly improve the sealing effect, reduce water leakage, avoid safety hazards such as erosion of the dam foundation caused by leakage, and ensure the stable operation of the project. Specifically, the rotating component 3 is controlled by a PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0017] In this embodiment, two sets of support plates 201 are connected to the outer surface of the door panel 4. Each set of support plates 201 has a rotating support 202 hinged to its adjacent side via a pin 204. Each rotating support 202 has multiple fixing holes 203 on its outer surface. Through the coordinated use of the support plates 201, pins 204, rotating supports 202, and fixing holes 203, the movement trajectory of the door panel 4 can be accommodated, ensuring the flexibility and stability of the rotating assembly 3 and the door panel 4. The fixing holes 203 assist in the assembly of the fixing assembly 2 with other components, ensuring the overall stability of the fixing assembly. The structural stability of component 2 during weir gate operation provides a reliable support foundation for the rotating assembly 3 to drive the gate plate 4 to achieve opening and closing actions. The gate plate 4 is made of high-strength steel plate, and the outer surface of the gate plate 4 is equipped with sealing rubber strips. The high-strength steel plate gate plate 4 ensures that the gate plate 4 is not easily deformed or damaged when subjected to water flow load for a long time, ensuring the structural stability of the weir gate. At the same time, it has good wear resistance and fatigue resistance, and can resist the scouring and wear of impurities such as mud and sand in the water flow, reduce the wear of the plate caused by long-term use, extend the service life of the gate plate 4, and reduce the replacement frequency and maintenance costs.

[0018] In this embodiment, both fixing rods 301 are connected to the outer surface of the mounting bracket 1, and bearings 302 are fixedly connected to the outer surfaces of both fixing rods 301. A cylinder base 303 is connected to the outer ring of each of the two bearings 302. Two sets of rotating seat assemblies 304 are connected to the outer surface of the door panel 4. Each of the two rotating seat assemblies 304 has two pin holes 307 on its outer surface. A pin 305 is provided inside each of the two sets of pin holes 307. A cylinder push rod 306 is connected to the outer surface of each of the two pins 305. The bottom ends of both cylinder push rods 306 are connected to the top end of the cylinder base 303. The hydraulic system controls the extension and retraction of the cylinder push rod 306. One end of the cylinder push rod 306 is hinged to the cylinder base 303 fixed on the mounting support 1, and the other end is connected to the rotating seat assembly 304 through the pin 305. The rotating seat assembly 304 is connected to the gate panel 4, and the fixed rod 301 is rotatably connected to the cylinder base 303 through the bearing 302. Therefore, the extension and retraction of the cylinder push rod 306 will drive the rotating seat assembly 304 to rotate, which in turn will drive the cylinder base 303 to rotate using the bearing 302, ultimately realizing the rotation of the gate panel 4, thereby changing the opening degree of the weir gate.

[0019] Working principle: When it is necessary to adjust the opening angle of the weir gate, the hydraulic system is first started to control the extension and retraction of the cylinder push rod 306. When the cylinder push rod 306 extends and retracts, the pin 305 drives the rotating seat assembly 304 to rotate, which in turn drives the fixed rod 301 to rotate around the bearing 302. This causes the fixed rod 301 to rotate the gate plate 4, thereby effectively changing the angle between the gate plate 4 and the horizontal plane, and realizing the adjustment of water level and flow. During the rotation of the gate plate 4, the rotating support 202 can rotate appropriately around the first pin 204 to adapt to the movement trajectory of the gate plate 4 and prevent damage to the device.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
