[0002] Gates are control facilities used to close and open water channels. They are an important component of hydraulic structures, used to intercept river flow, control water levels, regulate flow, and discharge sediment and floating debris. With the continuous development of science and technology, hydraulic gate equipment has been widely used due to its unique advantages. Closing gates can block floods, tides, or raise upstream water levels to meet the water needs of irrigation, power generation, navigation, aquaculture, environmental protection, and other social uses; opening gates can discharge floodwater, drain waterlogged areas, flush sediment, or regulate downstream water flow.

[0034] A connecting rod 204 is rotatably connected between the two sets of support blocks via bearings. Two winding rollers 205 are fixed to the surface of the connecting rod 204. A steel cable 206 is wound around the surface of the winding rollers 205. One end of the steel cable 206 is fixed to the top of the gate body 102, and the other end of the steel cable 206 is fixed to the surface of the winding rollers 205. A turbine 203 that meshes with the worm gear 202 is fixed to one end of the connecting rod 204.
[0035] A reinforcing block is fixed to the side wall of frame 101 near the worm 202, and one end of the worm 202 is rotatably connected to the reinforcing block through a bearing;
[0036] The extrusion mechanism 3 is installed on one side of the frame 101. The extrusion mechanism 3 can apply a lateral extrusion force to the gate body 102 towards the sealing strip 103.
[0037] The extrusion mechanism 3 includes a second motor 301 fixed on the upper surface of the frame 101, a screw 302 fixed on the output end of the second motor 301, and a movable seat 303 threadedly connected to the surface of the screw 302.
[0038] L-shaped plates 306 are fixed on both sides of the movable seat 303. Rectangular plates 310 arranged symmetrically are fixed on the side of the frame 101 at the middle part of the gate body 102. An inclined block 311 is fixed on the side of the rectangular plate 310 near the gate body 102. A slider 312 is provided on one side of the inclined block 311. A connecting plate 307 is fixed on the upper surface of the slider 312. Multiple sets of working pins 308 slide through the through holes on the L-shaped plate 306. A spring 309 is wound around the surface of the working pin 308. The working pin 308 and the connecting plate 307 are fixedly connected. The two ends of the spring 309 are fixedly connected to the working pin 308 and the L-shaped plate 306 respectively.
[0039] Limiting plates 304 are fixed on both sides of the movable seat 303. The side wall of the frame 101 is provided with limiting grooves 305 that are adapted to the limiting plates 304. The limiting plates 304 and the frame 101 are slidably connected through the limiting grooves 305. One side of the slider 312 is provided with an inclined surface that is adapted to the inclined surface of the inclined block 311. The screw 302 is rotatably connected to the frame 101 through a bearing.
[0040] In this implementation plan: The water conservancy project is designed with a lifting gate. When it is necessary to lift and release the gate body 102, the motor 201 is started, which drives the worm gear 202 to rotate. Since the worm gear 202 and the turbine 203 are meshed, the turbine 203 is driven to rotate. The turbine 203 drives the connecting rod 204 to rotate, which in turn drives the two sets of winding rollers 205 to rotate synchronously, so as to wind up the steel cable 206 on the winding rollers 205. The steel cable 206 lifts the gate body 102, so that the gate body 102 slides upward in the sliding groove opened in the frame 101, thereby realizing the gate release operation. The reverse operation of the motor 201 releases the steel cable 206, so that the gate body 102 moves downward by its own weight, thereby sealing the frame 101.
[0041] Then, motor 301 is started, which drives screw 302 to rotate. Since screw 302 is threadedly connected to moving seat 303, it drives limiting plate 304 to slide within limiting groove 305 opened in frame 101. The limiting plate 304 and limiting groove 305 limit the moving seat 303, making the moving seat 303 more stable during movement. As the moving seat 303 moves down, it drives L-shaped plate 306 to move down. L-shaped plate 306 drives the tool pin 308, connecting plate 307 and slider 312 to move down synchronously. Since one side of the inclined surface of slider 312 is on the inclined block 311... The slider 312 slides on the inclined plane, at which time the connecting plate 307 moves towards the gate body 102. At the same time, the pin 308 on the connecting plate 307 slides on the L-shaped plate 306 and compresses the spring 309. As the slider 312 moves down and laterally, it applies a lateral squeezing force to the gate body 102. During the squeezing process, the gate body 102 squeezes the sealing strip 103, thereby increasing the sealing performance of the connection between the gate body 102 and the frame 101. After the gate is closed, there will be no leakage, improving the sealing effect. This structure has a better performance and meets the actual use requirements.
[0042] It should be noted that after the steel cable 206 is released from the gate body 102, the steel cable 206 is in a non-taut state, so it does not affect the lateral movement of the gate body 102.
[0043] Furthermore;
[0044] In an optional embodiment, a rectangular groove is provided on the slider 312, and multiple sets of rollers 313 are provided in the rectangular groove. The rollers 313 and the slider 312 are rotatably connected by a rotating shaft, and the rolling surface of the rollers 313 abuts against the surface of the gate body 102.
[0045] In this embodiment, while the slider 312 moves downward and laterally, the roller 313 can reduce the friction between the slider 312 and the gate body 102, thereby avoiding wear on the slider 312 and the gate body 102, and further improving the performance of the device.
[0046] The working principle and usage process of this utility model: This water conservancy project uses a lifting-type water gate. During use, when it is necessary to lift and release the gate body 102, the motor 201 is started, which in turn drives the worm gear 202 to rotate. Since the worm gear 202 and the turbine 203 are meshed, the turbine 203 is driven to rotate, which in turn drives the connecting rod 204 to rotate, thereby driving the two sets of winding rollers 205 to rotate synchronously, thus controlling the steel cable on the winding rollers 205. 206 is wound up, thereby lifting the gate body 102 via the steel cable 206, causing the gate body 102 to slide upward within the sliding groove opened in the frame 101, thus realizing the gate release operation. The reverse operation of motor 201 releases the steel cable 206, causing the gate body 102 to move downward under its own weight, thus sealing the frame 101. Subsequently, motor 301 is started, driving the screw 302 to rotate. Due to the thread between the screw 302 and the moving seat 303... The connection causes the limiting plate 304 to slide within the limiting groove 305 opened in the frame 101. The limiting plate 304 and the limiting groove 305 limit the movement of the movable seat 303, making it more stable during movement. As the movable seat 303 moves downward, it causes the L-shaped plate 306 to move downward. The L-shaped plate 306 then causes the tool pin 308, connecting plate 307, and slider 312 to move downward synchronously. Because one side of the slider 312 is inclined at the inclined block 311... The slider 312 slides on the inclined surface. At this time, the slider 312 drives the connecting plate 307 to move towards the gate body 102. At the same time, the fork pin 308 on the connecting plate 307 slides on the L-shaped plate 306 and compresses the spring 309. As the slider 312 moves down and laterally, it applies a lateral squeezing force to the gate body 102. During the squeezing process, the gate body 102 squeezes the sealing strip 103, thereby increasing the sealing performance of the connection between the gate body 102 and the frame 101.
