Description

Technical Field

[0001] This utility model relates to the field of hydraulic rotary weir gate technology, and in particular to an intelligent hydraulic rotary weir gate. Background Technology

[0002] Intelligent hydraulic rotary weir gates are commonly used flow control devices in water conservancy projects and urban drainage systems. They use a hydraulic drive mechanism to rotate the main body of the weir gate, thereby adjusting the opening height of the weir gate and accurately controlling the water flow. They are widely used in river regulation, sewage treatment plant effluent discharge, and urban flood control.

[0003] In actual operation, the water bodies where the weir gate is located usually contain a large amount of floating impurities such as aquatic plants, branches, plastic bags, and woven materials. These impurities are easily entangled by the water flow and become entangled in the rotating shaft, blades, and hydraulic drive connection parts of the rotary weir gate. In existing technologies, some rotary weir gates do not have a dedicated anti-entanglement structure. After impurities become entangled, the weir gate will become stuck in rotation, and the load on the hydraulic system will increase sharply. This not only affects the flow regulation accuracy of the weir gate, but also easily causes damage to hydraulic components and wear on the weir gate structure. In the few weir gates that are equipped with anti-entanglement structures, the anti-entanglement components are mostly integrated with the main body of the weir gate, which is difficult to disassemble and clean. Maintenance requires stopping the machine to disassemble the main body of the weir gate, which is time-consuming and labor-intensive. Moreover, some anti-entanglement components are made of ordinary steel, which is prone to corrosion in the humid underwater environment and has a short service life. Therefore, we propose an intelligent hydraulic rotary weir gate. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides an intelligent hydraulic rotary weir gate. Floating impurities such as aquatic plants and branches in the water flow are intercepted by the comb teeth on the outside of the weir gate, preventing them from contacting key parts such as the rotating shaft and blades of the main body of the rotary weir gate. This avoids problems such as weir gate rotation jamming and excessive load on the hydraulic system caused by impurities entangled in the water, ensuring the flow regulation accuracy and normal operation of the intelligent hydraulic rotary weir gate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an intelligent hydraulic rotating weir gate, including a rotating weir gate body, a U-shaped interception frame on one side of the rotating weir gate body, comb teeth on the inner side of the U-shaped interception frame, side connecting plates integrally formed on both sides of the U-shaped interception frame, the side connecting plates being movably connected to the outer side of the rotating weir gate body and having a main fixing bolt at the connection point, a mounting screw at the top of the comb teeth, a through groove at the top of the inner side of the U-shaped interception frame, the mounting screw being movably connected to the inner side of the through groove, and a mounting nut being threaded onto the mounting screw.

[0006] As a preferred technical solution of this utility model, the inner side of the U-shaped interceptor is provided with an installation groove along the vertical direction, the outer side of the comb teeth is provided with a support rod, one end of the support rod is movably connected to the inner side of the installation groove, and the connection between the support rod, the U-shaped interceptor, the installation groove, and the comb teeth is provided with installation bolts.

[0007] As a preferred embodiment of this invention, the tips of the comb teeth have a smooth, rounded surface structure.

[0008] As a preferred technical solution of this utility model, the U-shaped interceptor is a frame structure formed by welding stainless steel rectangular tubes, and the comb teeth are long strip structures cut from high-strength stainless steel plates.

[0009] As a preferred embodiment of this utility model, the number of support rods is two, and the two support rods are respectively positioned at the upper and lower parts of the comb teeth and are arranged parallel to each other in the mounting groove.

[0010] As a preferred embodiment of this utility model, the bottom of the U-shaped interceptor frame is provided with a threaded groove, and a connecting screw is threadedly connected in the threaded groove. A positioning plug is fixedly connected to the bottom end of the connecting screw, and the positioning plug is arranged at equal intervals around the bottom end of the U-shaped interceptor frame.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. By setting the U-shaped interceptor frame and comb teeth, floating impurities such as aquatic plants and branches in the water flow are intercepted by the comb teeth on the outside of the weir gate, and cannot contact the key parts such as the rotating shaft and blades of the rotating weir gate body. This avoids problems such as weir gate rotation jamming and excessive load on the hydraulic system caused by impurities entanglement from the source, and ensures the flow regulation accuracy and normal operation of the intelligent hydraulic rotating weir gate.

[0012] 2. With the positioning rod, when this device is placed in a river, it can establish a certain connection between the U-shaped interceptor frame and the silt at the bottom of the water, making the device more stable and able to withstand the impact of the water flow.

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0019] like Figures 1-4 As shown, an intelligent hydraulic rotary weir gate includes a rotary weir gate body 1. A U-shaped intercepting frame 2 is provided on the water-facing side of the rotary weir gate body 1. The U-shaped intercepting frame 2 is a frame structure formed by welding stainless steel rectangular tubes. Its overall outline is adapted to the rotation trajectory of the rotary weir gate body 1. Its height is slightly higher than the maximum lifting height of the rotary weir gate body 1, and its width is consistent with the total width of the blades of the rotary weir gate body 1.

[0020] The U-shaped interceptor 2 has side connecting plates 21 integrally formed on both sides. The side connecting plates 21 have mounting holes. The main fixing bolts 22 pass through the mounting holes to movably connect the side connecting plates 21 to the concrete gate pier or steel structure frame on the outside of the rotating gate body 1. The U-shaped interceptor 2 can be fixed by tightening the main fixing bolts 22, and the relative position of the U-shaped interceptor 2 and the rotating gate body 1 can be adjusted by loosening them.

[0021] The U-shaped interceptor frame 2 has a vertically oriented mounting groove 23 on its inner side. Several comb teeth 3 are also provided on the inner side of the U-shaped interceptor frame 2. The comb teeth 3 are long strips cut from high-strength stainless steel plates, with smooth, rounded tips to avoid scratching the blades of the rotating weir gate body 1 and to reduce water flow resistance. Two support rods 4 are provided on the outer side of the comb teeth 3, corresponding to the upper and lower parts of the comb teeth 3 respectively, and are arranged parallel to each other within the mounting groove 23. One end of the support rod 4 is embedded in the inner side of the mounting groove 23 and is movably connected by a mounting bolt 41. The mounting bolt 41 passes through the support rod 4, the side wall of the mounting groove 23, and the corresponding position of the comb teeth 3, thus achieving a fixed connection between the support rod 4 and the U-shaped interceptor frame 2 and the comb teeth 3.

[0022] The top of the comb tooth 3 is fixedly provided with a mounting screw 31. The top of the inner side of the U-shaped interceptor 2 is provided with a through groove 24. The mounting screw 31 is movably inserted into the inside of the through groove 24. Two mounting nuts 32 are threadedly connected to the mounting screw 31. The two mounting nuts 32 abut against the upper and lower surfaces of the through groove 24 respectively. By tightening the mounting nuts 32, the top of the comb tooth 3 can be fixed. By loosening them, the installation height and angle of the comb tooth 3 can be adjusted.

[0023] The bottom of the U-shaped interceptor frame 2 has multiple threaded grooves 25, which are evenly distributed around the bottom of the U-shaped interceptor frame 2. Each threaded groove 25 is threaded with a connecting screw 26. The bottom of the connecting screw 26 is welded and fixed with a positioning rod 27. The bottom of the positioning rod 27 is conical. During installation, the positioning rod 27 is inserted into the concrete foundation below the rotating weir gate body 1 to further enhance the installation stability of the U-shaped interceptor frame 2 and prevent the U-shaped interceptor frame 2 from shifting due to water flow impact.

[0024] During actual installation, first, screw the positioning rod 27 into the threaded groove 25 at the bottom of the U-shaped interceptor frame 2 via the connecting screw 26, and then insert the positioning rod 27 into the concrete / silt foundation to achieve initial positioning. Next, fix the side connecting plate 21 to the mounting base outside the rotating weir gate body 1 using the main fixing bolt 22, and adjust the horizontal distance between the U-shaped interceptor frame 2 and the rotating weir gate body 1 to 5-10mm. Then, insert the top mounting screw 31 of the comb teeth 3 into the through groove 24, tighten the mounting nut 32 to fix the top of the comb teeth 3, and then embed the support rod 4 into the mounting groove 23. Fix the support rod 4, comb teeth 3, and U-shaped interceptor frame 2 with the mounting bolt 41 to complete the overall installation. During maintenance and cleaning, the mounting nut 32 and mounting bolt 41 can be loosened to disassemble the comb teeth 3 separately to clean impurities, or the main fixing bolt 22 can be loosened to disassemble the U-shaped interceptor frame 2 as a whole for thorough maintenance.

[0025] The anti-entanglement effect is significant, ensuring the normal operation of the weir gate: By installing a U-shaped interceptor 2 and comb teeth 3 on the outside of the main body 1 of the rotating weir gate, floating impurities such as aquatic plants and branches in the water flow are intercepted by the comb teeth 3 on the outside of the weir gate, preventing them from contacting the rotating shaft, blades, and other critical parts of the main body 1 of the rotating weir gate. This avoids problems such as weir gate rotation jamming and excessive load on the hydraulic system caused by impurities entanglement from the source, ensuring the flow regulation accuracy and normal operation of the intelligent hydraulic rotating weir gate. The smooth arc surface structure of the comb teeth 3 not only avoids scratching the weir gate blades but also reduces the impact resistance of the water flow on the comb teeth 3, further improving operational stability.

[0026] Easy to install and disassemble, and high maintenance efficiency: The anti-winding components of this utility model are all externally added structures, without needing to modify the original structure of the rotating weir gate body 1; the side connecting plate 21 is movably connected by the main fixing bolt 22, the comb teeth 3 are connected to the U-shaped interceptor frame 2 by the mounting screw 31 and the mounting nut 32, and the support rod 4 is detachably fixed by the mounting bolt 41. During maintenance, the comb teeth 3 can be disassembled separately to clean impurities, or the U-shaped interceptor frame 2 can be disassembled as a whole without stopping the machine to disassemble the weir gate body, which greatly reduces the maintenance difficulty and improves the maintenance efficiency.

[0027] High structural stability and long service life: The U-shaped interceptor frame 2 is welded from stainless steel rectangular tubes, and the comb teeth 3 are made of high-strength stainless steel plates, which have excellent corrosion resistance and are suitable for underwater humid working environments, thus extending the service life of the components; the positioning rod 27 set at the bottom of the U-shaped interceptor frame 2 forms a double fixation with the main fixing bolt 22, which effectively prevents the U-shaped interceptor frame 2 from shifting due to water flow impact. The two parallel support rods 4 provide upper and lower support for the comb teeth 3, preventing the comb teeth 3 from deforming due to water flow impact, further enhancing the overall structural stability.

[0028] Highly adaptable and versatile: The installation height and angle of the comb teeth 3 can be changed by adjusting the installation nut 32. The positioning rod 27 is threadedly connected to the threaded groove 25 through the connecting screw 26. The insertion depth can be adjusted according to the actual situation of the installation foundation. Moreover, the size of the U-shaped interceptor frame 2 can be customized according to different specifications of the rotating weir gate body 1, adapting to different models of intelligent hydraulic rotating weir gates, and has high versatility.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
