Abstract
Description
Technical Field
[0001] This utility model relates to a gate structure, specifically a gate structure for a small river channel, and belongs to the technical field of water conservancy engineering equipment. Background Technology
[0002] A sluice gate is a low-head hydraulic structure built on rivers and canals to control flow and regulate water levels. Closing the gates can impound floodwaters, block tides, or raise upstream water levels to meet needs for irrigation, power generation, navigation, aquaculture, environmental protection, industrial, and domestic water use. Opening the gates can release floodwaters, waterlogged water, sewage, or wastewater, and can also supply water to downstream rivers or canals. In water conservancy projects, sluice gates are widely used as structures for impounding, releasing, or drawing water.
[0003] For example, the temporary water-retaining structure for a river culvert that can be quickly disassembled, as described in authorization announcement number CN218027767U, effectively speeds up the assembly and disassembly of the water-retaining structure by combining mounting plates, fixing piles, bearings, rocker arms, threaded rods, through holes, threaded holes, connecting plates, baffles, built-in grooves, limit bolts, and extension plates, reducing the labor intensity of operators during assembly and disassembly. Furthermore, the height of the water-retaining structure can be adjusted according to the depth of the river culvert. However, when placed in the river, the varying widths of different parts of the river and the need to adjust the placement of the water-retaining mechanism according to the needs of the workers, coupled with the fact that the width of the water-retaining structure cannot be adjusted, render it ineffective in blocking the river, resulting in poor performance.
[0004] Therefore, a gate structure for small river channels is proposed here. Utility Model Content
[0005] This utility model proposes a gate structure for small river channels to solve the problem that the width of the water-retaining structure in the prior art cannot be adapted to the width of the river channel, thus making it impossible for the water-retaining structure to block the river channel.
[0006] This utility model is achieved through the following technical solution: a gate structure for a small river channel, including a river channel body and a support frame installed inside the river channel body. The support frame is provided with a gate body on its side. The surface of the gate body is provided with a movable plate and a movable component. The movable plate is movably connected to one side of the gate body through the movable component.
[0007] The moving component includes a first motor and a fixed plate. The fixed plate is fixed to the side of the gate body. The output shaft of the first motor rotates through the fixed plate via a bearing. The moving component also includes a first threaded rod, a threaded cap, a connecting block, a connecting rod, and a connecting plate. The connecting plate is fixed to the side of the moving plate.
[0008] Furthermore, one end of the first threaded rod is fixed to the output shaft of the first motor, and there are two fixing plates, which are respectively set on the upper and lower parts of the side of the gate body. The other end of the first threaded rod is rotatably connected to the side of another fixing plate through a bearing, and the threaded cap is threadedly connected to the surface of the first threaded rod.
[0009] Furthermore, the connecting block is fixed to the side of the threaded cap, one end of the connecting rod is hinged to the connecting block by a pin, and the other end of the connecting rod is hinged to the side of the connecting plate by a pin. The first threaded rod is a bidirectional threaded rod. There are two sets of the threaded cap, the connecting block, and the connecting rod, which are symmetrically arranged on the surface of the first threaded rod.
[0010] Furthermore, the gate body has a telescopic groove on its side, the movable plate passes through the telescopic groove, a support plate is fixed to the side of the movable plate, a sliding groove is provided on the inner wall of the telescopic groove, the support plate is slidably connected in the sliding groove, and the movable plate moves in the telescopic groove through the support plate and the sliding groove. There are two sets of support plates and sliding grooves, which are symmetrically arranged on both sides of the movable plate.
[0011] Furthermore, a second motor is fixed to the surface of the support frame, and a second threaded rod is fixed to the output shaft of the second motor. The lower end of the second threaded rod passes through the support frame via a bearing. A threaded hole is opened on the surface of the gate body, and the lower end of the second threaded rod is threaded into the threaded hole.
[0012] Furthermore, the support frame has a movable groove on its side, and one side of the movable plate is engaged in the movable groove. The movable plate and the valve body slide in the movable groove via a second motor and a second threaded rod.
[0013] Furthermore, a buffer frame is fixed to the other side of the support frame relative to the moving component, and a buffer wheel is installed inside the buffer frame. The buffer wheel is turbine-shaped.
[0014] This utility model provides a gate structure for small river channels, which has the following beneficial effects:
[0015] 1. The gate structure of this small river channel uses a moving component. The motor drives the first threaded rod to rotate, and the first threaded rod drives the threaded cap to move, thereby moving the connecting rod and the connecting plate. This pushes the moving plate out of the expansion groove, thereby increasing the overall width of the valve body. This allows the valve body and the moving plate to completely block the river channel, adapting to river channels of different widths and improving the overall range of use.
[0016] 2. The gate structure of this small river channel uses a buffer plate and a buffer wheel. Before the water impacts the gate body, it is first blocked by the buffer plate. At the same time, the water flow drives the buffer wheel to rotate. The rotation of the turbine will put resistance to the water flow, thereby slowing down the water flow speed and reducing the impact pressure of the water flow on the gate body, protecting the gate. Furthermore, by connecting the turbine to external power generation equipment, some of the kinetic energy of the water flow can be recovered, improving the energy efficiency of the overall system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0026] Please see Figures 1-4 This utility model embodiment provides a gate structure for a small river channel, including a river channel body 1 and a support frame 2 installed inside the river channel body 1.

[0027] Please refer to this carefully. Figure 2 and Figure 4 The moving component 4 includes a first motor 401 and a fixed plate 407. The fixed plate 407 is fixed to the side of the gate body 3. The output shaft of the first motor 401 rotates through the fixed plate 407 via a bearing. The moving component 4 also includes a first threaded rod 402, a threaded cap 403, a connecting block 404, a connecting rod 405, and a connecting plate 406. The connecting plate 406 is fixed to the side of the moving plate 5. One end of the first threaded rod 402 is fixed to the output shaft of the first motor 401. There are two fixed plates 407, which are respectively set on the upper and lower parts of the side of the gate body 3. The other end of the first threaded rod 402 is rotatably connected to the side of another fixed plate 407 via a bearing. The threaded cap 403 is threadedly connected to the surface of the first threaded rod 402. The connecting block 404 is fixed to the side of the threaded cap 403. The connecting rod 405... One end of the connecting rod 405 is hinged to the connecting block 404 via a pin, and the other end of the connecting rod 405 is hinged to the side of the connecting plate 406 via a pin. The first threaded rod 402 is a bidirectional threaded rod. There are two sets of threaded caps 403, connecting blocks 404, and connecting rods 405, which are symmetrically arranged on the surface of the first threaded rod 402. The gate structure of this small river channel uses the moving component 4 to drive the first threaded rod 402 to rotate via a motor. The first threaded rod 402 drives the threaded cap 403 to move, thereby driving the connecting rod 405 and the connecting plate 406 to move, and then pushing the moving plate 5 out of the telescopic groove 301, thereby increasing the overall width of the valve body, so that the valve body and the moving plate 5 can completely block the river channel, adapt to river channels of different widths, and improve the overall application range.
[0028] Please refer to this carefully. Figure 4 The gate body 3 has a telescopic groove 301 on its side, and the movable plate 5 passes through the telescopic groove 301. A support plate 501 is fixed on the side of the movable plate 5. A sliding groove 302 is provided on the inner wall of the telescopic groove 301. The support plate 501 is slidably connected in the sliding groove 302. The movable plate 5 moves in the telescopic groove 301 through the support plate 501 and the sliding groove 302. There are two sets of support plates 501 and sliding grooves 302, which are symmetrically arranged on both sides of the movable plate 5.
[0029] Please refer to this carefully. Figure 1 and Figure 2 A second motor 6 is fixed to the surface of the support frame 2. A second threaded rod 601 is fixed to the output shaft of the second motor 6. The lower end of the second threaded rod 601 passes through the support frame 2 through a bearing. A threaded hole 303 is opened on the surface of the gate body 3. The lower end of the second threaded rod 601 is threaded into the threaded hole 303. A movable groove 201 is opened on the side of the support frame 2. One side of the movable plate 5 is engaged in the movable groove 201. The movable plate 5 and the valve body slide in the movable groove 201 through the second motor 6 and the second threaded rod 601.
[0030] Please refer to this carefully. Figure 3On the other side of the support frame 2 relative to the moving component 4, a buffer frame 7 is also fixed. The buffer frame 7 is equipped with a buffer wheel 701, which is turbine-shaped. The gate structure of this small river channel, through the buffer plate and the buffer wheel 701, first blocks the water before it impacts the gate body 3. At the same time, the water flow drives the buffer wheel 701 to rotate. The rotation of the turbine will put resistance on the water flow, thereby slowing down the speed of the water flow and reducing the impact pressure of the water flow on the gate body, protecting the gate. Furthermore, by connecting the turbine to the external power generation equipment, some of the kinetic energy of the water flow can be recovered, improving the energy efficiency of the overall system.
[0031] In use, the device is first installed at a designated location on the main body 1 of the river channel and connected to an external control device and a 220V mains power supply. The control device can be a conventional known device such as a computer. Then, the operator controls the first motor 401 through the external control device. The first motor 401 drives the first threaded rod 402 to rotate, and the first threaded rod 402 drives the threaded cap 403 to move, thereby driving the connecting block 404 and the connecting rod 405 to move synchronously, thus pushing the moving plate 5 out of the telescopic groove 301, thereby increasing the overall width of the valve body. When one side of the moving plate 5 is engaged in the movable groove 201, the operator can control the first motor 401 to stop operating and control the second motor 6 to operate. The second motor 6 drives the second threaded rod 601 to rotate, thereby driving the gate body 3 and the moving plate 5 to move downward, thus blocking the river channel.
