Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a gate sealing device for water conservancy projects. Background Technology

[0002] Gates in water conservancy projects are key equipment for controlling water flow and regulating water levels, widely used in reservoirs, dams, locks, irrigation systems, and other facilities. Gates regulate water flow by opening or closing, preventing water levels from becoming too high or too low, and ensuring the safety of downstream areas. Common gate types include hinged gates, sliding gates, and lifting gates. Their sealing performance, structural strength, and corrosion resistance are important considerations in design and use, ensuring the normal operation of water conservancy projects and flood control safety. To guarantee the full utilization of water resources, high sealing performance is required for gates, necessitating the use of a gate sealing device for water conservancy projects.

[0003] According to the Chinese patent "A Gate for Opening and Closing Water Conservancy Projects" authorized announcement number "CN221972275U", the gate uses a combination of a sealing groove, a reset cavity, a guide rod, a slider, a sliding hole, a spring, a limit plate, and a positioning plate. When the gate is opened, the spring rebounds, which pushes the slider to rise and seal the sealing groove. Thus, when the river water flows after the gate is opened, it can effectively prevent silt from settling into the sealing groove and affecting the sealing performance of the gate when it is closed, thereby improving the sealing performance after the gate is closed.

[0004] Although the above application can prevent silt from settling into the groove when the gate is opened by using a spring and slider to make the water flow match the gate opening, thus improving the sealing performance when the gate is closed, the flood discharge usually ends and the water flow is small. At the same time, sediments such as silt may accumulate near the slider and cannot be cleared by the water flow. When the gate is closed at this time, gaps may exist at the bottom of the gate, resulting in a decrease in the sealing performance of the gate.

[0005] Therefore, a gate sealing device for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a gate sealing device for water conservancy projects to solve the above-mentioned problems and improve the problem of reduced sealing performance of gates when closed.

[0007] The present invention achieves the above objectives through the following technical solution: a gate sealing device for water conservancy projects, comprising: a gate frame installed in a river channel, wherein two outer gates are provided inside the gate frame;

[0008] The cleaning mechanism includes an inner gate disposed between two outer gates. Two cleaning plates are rotatably connected to the lower inner wall of the inner gate. Two limiting grooves are opened on the inner wall of the inner gate. Two fixing blocks are fixedly connected to both sides of the inner gate. Two sliding grooves are opened on the side of the two outer gates near the inner gate at the corresponding positions of the fixing blocks.

[0009] Preferably, a first groove is formed on the inner wall of the bottom end of the gate frame, and a spring plate is slidably connected in the first groove. Multiple first springs are fixedly connected between the spring plate and the inner bottom wall of the gate frame. This ensures a more airtight seal when the gate is closed and allows impurities to be cleared out when the gate is opened.

[0010] Preferably, the gate frame has second grooves on both sides of the first groove, and spring blocks are slidably connected in the second grooves. Two second springs are fixedly connected to the inner walls of both sides of the gate frame in the spring blocks. This allows the second grooves to form spaces for storing impurities.

[0011] Preferably, the two cleaning plates are two opposing fan-shaped structures with serrated arc surfaces. The drive assembly includes a protective cover mounted on the top of the gate frame. A drive motor and a rotating rod are housed inside the protective cover. One end of the rotating rod is rotatably connected to the inner wall of the protective cover, and the other end is fixedly connected to the drive end of the drive motor. This controls the opening and closing of the gate.

[0012] Preferably, the rotating rod has two fixed wheels fixedly connected to its surface, and the fixed wheels are provided with steel cables on their surfaces. The steel cables pass through the top of the gate frame and are fixedly connected to the inner gate.

[0013] Preferably, the inner walls on both sides of the gate frame are provided with slide rails, and the two outer gates are slidably connected to the slide rails on both sides. This makes the gate movement more stable.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting two outer gates in conjunction with the inner gate, a three-layer isolation is formed, which enhances the isolation of water flow. When the inner gate is closed, the cleaning plate will first clean the sediment such as mud and sand on the spring plate into the second trough, and then the inner gate will enter the compression spring plate and enter the first trough, so that the inner gate and the first trough fit more tightly, avoiding gaps caused by mud and sand on the surface of the spring plate, and strengthening the sealing performance when the gate is closed.

[0016] 2. By setting up a second groove and a spring block, when the gate is closed, impurities on the spring plate can be pushed into the second groove, making the surface of the spring plate cleaner. When the gate is opened, the spring plate will push out the impurities in the second groove, and together with the water flow, the impurities in the second groove will be cleaned.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-5 As shown, a gate sealing device for water conservancy projects includes: a gate frame 100 installed in a river channel, and two outer gates 300 are provided inside the gate frame 100;

[0025] The cleaning mechanism 200 includes an inner gate 210 disposed between two outer gates 300. Two cleaning plates 220 are rotatably connected to the lower inner wall of the inner gate 210. Two limiting grooves 221 are opened on the inner wall of the inner gate 210. Two fixing blocks 211 are fixedly connected to both sides of the inner gate 210. Two sliding grooves 310 are opened on the side of the two outer gates 300 near the inner gate 210 at the corresponding positions of the fixing blocks 211.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, a first groove 232 is provided on the inner wall of the bottom end of the gate frame 100. A spring plate 230 is slidably connected in the first groove 232. A plurality of first springs 231 are fixedly connected between the spring plate 230 and the inner bottom wall of the gate frame 100. A second groove 242 is provided on both sides of the first groove 232 of the gate frame 100. A spring block 240 is slidably connected in the second groove 242. Two second springs 241 are fixedly connected between the spring block 240 and the inner walls of both sides of the gate frame 100. The two cleaning plates 220 are two fan-shaped oppositely arranged. The arc surface of the cleaning plate 220 is sawtooth-shaped. A drive assembly 400 is provided between the inner gate 210 and the gate frame 100. A slide rail 110 is provided on both sides of the inner wall of the gate frame 100. The two outer gates 300 are slidably connected to the slide rail 110 on both sides.

[0027] In this embodiment, when the cleaning plate 220 just contacts the spring plate 230, the two outer gates 300 close simultaneously, making the space inside the two outer gates 300 relatively sealed, thus preventing the continuous flow of water during the closing process from causing impurities to remain. While the cleaning plate 220 slides on the surface of the spring plate 230, it pushes the impurities on the surface of the spring plate 230 to both sides of the spring plate 230 or into the second groove 242. At the same time, the spring block 240 compresses the second spring 241. When the gate is opened again, the two cleaning plates 220 will rotate inward first. Under the action of the second spring 241, the spring block 240 in the second groove 242 will push the impurities from the second groove 242 to the surface of the spring plate 230. After the cleaning plate 220 leaves the surface of the spring plate 230, the spring plate 230, under the action of the first spring 231, pushes the impurities to a position flush with the surface of the gate frame 100, where they are washed away by the water flow.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly 400 includes a protective cover 410 mounted on the top of the gate frame 100. Inside the protective cover 410 are a drive motor 420 and a rotating rod 440. One end of the rotating rod 440 is rotatably connected to the inner wall of the protective cover 410, and the other end is fixedly connected to the drive end of the drive motor 420. Two fixed wheels 430 are fixedly connected to the surface of the rotating rod 440. A steel cable 450 is mounted on the surface of the fixed wheels 430, passing through the top of the gate frame 100 and fixedly connected to the inner gate 210. The drive motor 420 drives the rotating rod 440 to rotate via its drive end. The rotation of the rotating rod 440 drives the fixed wheels 430 to rotate. The rotation of the fixed wheels 430 adjusts the raising and lowering of the steel cable 450, thereby adjusting the raising and lowering of the inner gate 210.

[0029] When using this utility model, the device is first installed in a pre-set river channel, and the gate is opened and closed by controlling the drive motor 420 according to the weather conditions.

[0030] When it is necessary to discharge floodwater into the river, the inner gate 210 is raised by controlling the drive motor 420. When the inner gate 210 rises, it first slides upward between the two outer gates 300 via the fixing block 211. When the fixing block 211 slides to the top of the slide groove 310, the cleaning plate 220 is in a vertical downward state and its bottom end is flush with the bottom end of the outer gate 300. At this time, the inner gate 210 continues to rise, and the outer gates 300 are moved upward by the fixing block 211, so that the two outer gates 300 slide along the slide rail 110. When all the gates rise to the appropriate position, the drive motor 420 is turned off, so that the gates remain open and the flood discharge is completed.

[0031] When the flood discharge is completed and the gate needs to be closed, the inner gate 210 is lowered by controlling the drive motor 420. Under the action of gravity, the outer gate 300 is lowered synchronously. When the outer gate 300 merges with the bottom of the gate frame 100, the inner gate 210 continues to descend. At this time, the teeth of the cleaning plate 220 will slide along the spring plate 230 and rotate relative to each other, cleaning the impurities on the surface of the spring plate 230. The inner gate 210 continues to descend until the inner gate 210 compresses the first spring 231 through the spring plate 230, thus completing the gate closure.

[0032] It should be noted that the drive motor 420 and steel cable 450 mentioned above are both devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the drive motor 420 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
