Abstract
Description
Technical Field
[0001] This invention belongs to the field of sluice gate structure technology, specifically a sluice gate structure for river management based on water conservancy engineering. Background Technology
[0002] Water conservancy projects utilize river sluice gates during the construction of canals or small waterways to control water flow. The primary function of a river sluice gate is to cut off and regulate water flow. A sluice gate typically includes a base with side plates on both sides, forming a flow channel. Gate tracks are installed on the side plates, and a gate slides along these tracks. A support plate is mounted above the side plates, and a lifting mechanism is installed on the support plate. The gate is raised or lowered by this mechanism to open or close. To improve the gate's sealing performance, sealing strips are typically installed on the gate tracks and at the bottom of the gate. The gate's cooperation with the sealing strips enhances the seal. However, when the gate is opened, the frictional resistance of the side sealing strips causes raising the gate to require more energy. Furthermore, the water flow inevitably contains debris; if debris is present at the bottom when the gate is lowered, gaps may form between the debris and the gate, preventing the gate from properly engaging with the sealing strips for a seal. Summary of the Invention
[0003] This invention addresses the shortcomings of existing technologies by providing a water gate structure for river management based on hydraulic engineering. This water gate structure can reduce friction between the gate and the sealing components when the gate is raised, thereby reducing energy consumption, and can also prevent garbage from accumulating at the gate's lowering position, effectively improving sealing performance.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a water gate structure for river management based on water conservancy engineering, comprising a base, side plates on both sides of the base, a flow channel formed between the two side plates, gate slides on the two side plates, a gate slidingly mounted on the gate slides, a closing slot on the base below the gate, a support plate above the side plates, a gate lifting mechanism on the support plate, a hollow elastic body connected as one unit in the two gate slides and the closing slot, a water pipe perpendicular to the closing slot in the base, the inlet and outlet of the water pipe located on both sides of the gate, a strip-shaped spray nozzle at the bottom of the closing slot connected to the water pipe, a Venturi tube on the water pipe located in front of the strip-shaped spray nozzle along the water flow direction, the suction pipe of the Venturi tube connected to the hollow elastic body, and a valve on the outlet. When this type of sluice gate is closed, the hollow elastic body is filled with water and is tightly sealed to the outer wall of the gate. When opening the gate to drain water, the valve is first opened, water enters through the inlet, and exits through the outlet via the water pipe. During the water flow in the water pipe, the Venturi tube generates negative pressure, drawing water from the hollow elastic body, creating a certain gap between the hollow elastic body on the side and the gate, or reducing the elasticity. Then, the gate is lifted by the gate lifting mechanism. During the gate lifting process, due to the gap between the hollow elastic body and the gate or the reduced elasticity, friction is reduced. The strip-shaped spray nozzle at the bottom of the gate, connected to the water pipe, provides a certain thrust, making the gate lifting more labor-saving and energy-efficient. When closing the gate, the valve is first closed, the outlet stops draining water, while the inlet continues to receive water. Water is injected into the hollow elastic body through the suction pipe of the Venturi tube. Then the gate moves down. During the downward movement of the gate, it squeezes the hollow elastic body on the side, causing the water inside the hollow elastic body to enter the water pipe through the suction pipe of the Venturi tube, and then spray out from the strip-shaped spray nozzle. This washes away the garbage and sludge above the spray nozzle, thus ensuring the sealing of the gate after it is closed.
[0005] In the above technical solution, preferably, a guide bracket is provided at the top of the gate, the guide bracket includes a top plate and a support plate, a guide rod is provided at the bottom of the support plate, a movable plate is slidably provided on the guide rod, the top of the movable plate is connected to the gate lifting mechanism, a spring is provided between the top plate and the movable plate, a connecting rod is vertically connected to the bottom of the movable plate, a rack is provided at the bottom of the connecting rod, the bottom of the rack is lower than the gate, a mating hole for inserting the rack is provided on the base, a drive rod for opening and closing the valve is provided on the valve, a gear is rotatably provided on the valve, the shaft of the gear is connected to the drive rod through a magnetic coupling, and the rack meshes with the gear. This structure provides a buffering effect during gate lifting. When the gate is opened, the lifting force of the gate lifting mechanism acts on the movable plate. As the movable plate rises, it first compresses the spring and drives the connecting rod to rise. During the rise of the connecting rod, the rack and pinion mesh and rotate, and the magnetic coupling drives the valve core inside the valve to rotate, thereby opening the valve. After the valve is fully opened, water enters through the inlet and exits through the outlet via the water pipe. During the water flow in the water pipe, the Venturi tube generates negative pressure to draw water from the hollow elastic body, creating a certain gap between the hollow elastic body on the side and the gate / or reducing the elastic force. After the movable plate contacts the support plate, the gate is lifted. Due to the certain gap between the hollow elastic body and the gate, or The reduced elasticity decreases friction, making gate lifting more effortless and energy-efficient. During gate ascent, the rack continues to drive the gear, while the magnetic coupling no longer drives the valve core. When closing the gate, the rack first engages with the gear, and the magnetic coupling drives the valve core inside the valve to rotate, thus closing the valve. The outlet stops draining water, while the inlet continues to receive water, which is injected into the hollow elastic body through the Venturi tube's suction pipe. As the gate descends, it squeezes the hollow elastic body on the side, causing the water inside to enter the water pipe through the Venturi tube's suction pipe and then spray out from the strip nozzle, washing away the garbage and sludge above the strip nozzle, thus ensuring the gate's seal after closing.
[0006] In the above technical solution, preferably, the gate lifting mechanism is a first winch, and the first winch is connected to the movable plate by a steel cable.
[0007] In the above technical solution, preferably, a guide portion is provided on the side of the gate, and the connecting rod passes through the guide portion. This structure is used to guide and support the connecting rod, making the lifting and operation of the connecting rod more stable and secure.
[0008] In the above technical solution, preferably, a filter screen is provided on the water inlet, the water outlet, and the strip-shaped spray nozzle. This structure prevents solid particles from entering and clogging the water pipe.
[0009] In the above technical solution, preferably, an isolation net is vertically installed between the two side plates, and a liftable basket is installed between the side plates. One side of the liftable basket is attached to the isolation net, and a lifting mechanism for the liftable basket is provided on the support plate. When the sluice gate is opened to allow water to flow, the isolation net can isolate garbage and aquatic plants, thereby reducing environmental pollution and preventing garbage and aquatic plants from sticking to the sluice gate and side plates and affecting the opening and closing of the sluice gate. Furthermore, the garbage and aquatic plants attached to the isolation net can be lifted and removed by raising and lowering the liftable basket.
[0010] Compared with existing technologies, this invention has the following advantages: When closed, the hollow elastic body of this sluice gate structure is filled with water, and the hollow elastic body is tightly sealed to the outer wall of the gate. When opening the gate to drain water, the valve is first opened, water enters through the inlet, and exits through the outlet via the water pipe. During the water flow in the water pipe, the Venturi tube generates negative pressure to draw water from the hollow elastic body, creating a certain gap between the hollow elastic body on the side and the gate / or reducing the elastic force. Then, the gate is lifted by the gate lifting mechanism. During the gate lifting process, due to the certain gap between the hollow elastic body and the gate or the reduction of the elastic force, water flows out from the outlet. This reduces friction, and the strip-shaped nozzles at the bottom of the gate, connected to the water pipe, provide a certain thrust, making gate lifting more labor-saving and energy-efficient. When closing the gate, the valve is first closed, the outlet stops draining, while the inlet continues to receive water. Water is injected into the hollow elastic body through the suction pipe of the Venturi tube. Then the gate moves down. During the downward movement of the gate, it squeezes the hollow elastic body on the side, causing the water inside the hollow elastic body to enter the water pipe through the suction pipe of the Venturi tube and then spray out from the strip-shaped nozzles. This washes away the garbage and sludge above the strip-shaped nozzles, thus ensuring the sealing of the gate after it is closed. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1 to 9 A water gate structure for river management based on water conservancy engineering includes a base 1, side plates 2 on both sides of the base 1 forming a flow channel between the side plates 2, gate slide rails 21 on the side plates 2, gates 3 slidably mounted on the gate slide rails 21, a closing groove 11 on the base 1 below the gates 3, a support plate 12 above the side plates 2, and a gate lifting mechanism 4 on the support plate 12. A connecting mechanism is provided within the two gate slide rails 21 and the closing groove 11. The hollow elastomer 5 has a water pipe 6 installed in the base 1 with a vertical closing slot 11. The inlet 61 and outlet 62 of the water pipe 6 are located on both sides of the gate 3. A strip-shaped spray nozzle 13 is installed at the bottom of the closing slot 11. The strip-shaped spray nozzle 13 is connected to the water pipe 6. A Venturi tube 63 is installed on the water pipe 6 located in front of the strip-shaped spray nozzle 13 along the water flow direction. The suction pipe of the Venturi tube 63 is connected to the hollow elastomer 5. A valve 7 is installed on the outlet 62. When this sluice gate structure is closed, the hollow elastic body 5 is filled with water, and the hollow elastic body 5 is tightly sealed to the outer wall of the gate 3. When opening the gate to drain water, firstly, valve 7 is opened, water enters through inlet 61, and exits through outlet 62 via water pipe 6. During the flow of water in water pipe 6, the venturi tube 63 generates negative pressure to draw water from the hollow elastic body 5, creating a certain gap between the hollow elastic body 5 on the side and the gate 3 / or reducing the elasticity. Then, the gate 3 is lifted by the gate lifting mechanism 4. During the lifting process of the gate 3, due to the certain gap between the hollow elastic body 5 and the gate 3 or the reduction of the elasticity, the friction is reduced, and the gate 3... The bottom strip-shaped spray nozzle 13, connected to the water pipe 6, provides a certain thrust, making the gate 3 easier and more energy-efficient to lift. When closing the gate 3, the valve 7 is closed first, the outlet 62 stops draining, while the inlet 61 continues to receive water. Water is injected into the hollow elastomer 5 through the suction pipe of the venturi tube 63. Then, the gate 3 moves down. During the downward movement of the gate 3, the gate 3 will squeeze the hollow elastomer 5 on the side, causing the water inside the hollow elastomer 5 to enter the water pipe 6 through the suction pipe of the venturi tube 63, and then spray out from the strip-shaped spray nozzle 13, which washes away the garbage and sludge above the strip-shaped spray nozzle 13, thus ensuring the sealing of the gate 3 after it is closed.
[0021] In this embodiment, a guide bracket 31 is provided on the top of the gate 3. The guide bracket 31 includes a top plate 32 and a support plate 33. A guide rod 34 is provided at the bottom of the support plate 33. A movable plate 35 is slidably provided on the guide rod 34. The top of the movable plate 35 is connected to the gate lifting mechanism 4. A spring 36 is provided between the top plate 32 and the movable plate 35. A connecting rod 37 is vertically connected to the bottom of the movable plate 35. A rack 38 is provided at the bottom of the connecting rod 37. The bottom of the rack 38 is lower than the gate 3. A mating hole for inserting the rack 38 is provided on the base 1. A drive rod 71 for opening and closing the valve 7 is provided on the valve 7. A gear 72 is rotatably provided on the valve 7. The shaft of the gear 72 is connected to the drive rod 71 through a magnetic coupling 73. The rack 38 meshes with the gear 72. This structure provides a buffering effect when the gate 3 is lifted. When the gate 3 is opened, the lifting force of the gate lifting mechanism 4 acts on the movable plate 35. When the movable plate 35 rises, it first compresses the spring 36 and drives the connecting rod 37 to rise. During the rise of the connecting rod 37, the rack 38 meshes with the gear 72 and rotates. The magnetic coupling 73 drives the valve core inside the valve 7 to rotate, thereby opening the valve 7. After the valve 7 is fully opened, water enters through the inlet 61 and is discharged from the outlet 62 through the water pipe 6. During the flow of water in the water pipe 6, the venturi tube 63 generates negative pressure to draw water from the hollow elastic body 5, creating a certain gap between the hollow elastic body 5 on the side and the gate 3, or reducing the elastic force. After the movable plate 35 contacts the support plate 33, the gate 3 is lifted. Due to the certain gap between the hollow elastic body 5 and the gate 3... Alternatively, the elasticity may be reduced, thereby reducing friction and making the lifting of the gate 3 more effortless and energy-efficient. During the upward movement of the gate 3, the rack 38 continues to drive the gear 72 to rotate, while the magnetic coupling 73 no longer drives the valve core to rotate. When the gate 3 is closed, the rack 38 first meshes with the gear 72, and the magnetic coupling 73 drives the valve core inside the valve 7 to rotate, thereby closing the valve 3. The outlet 62 stops draining water, while the inlet 61 continues to receive water. Water is injected into the hollow elastomer 5 through the suction pipe of the venturi tube 63. Then, during the downward movement of the gate 3, the gate 3 will squeeze the hollow elastomer 5 on the side, causing the water inside the hollow elastomer 5 to enter the water pipe 6 through the suction pipe of the venturi tube 63, and then spray out from the strip nozzle 13, so that the garbage and sludge above the strip nozzle 13 are washed away, thereby ensuring the sealing of the gate 3 after it is closed.
[0022] In this embodiment, the gate lifting mechanism 4 is a first winch, and the first winch is connected to the movable plate 35 by a steel cable.
[0023] In this embodiment, a guide portion 39 is provided on the side of the gate 3, and the connecting rod 37 passes through the guide portion 39. This structure is used to guide and support the connecting rod, making the lifting and operation of the connecting rod more stable and secure.
[0024] In this embodiment, filter screens 64 are provided on the water inlet 61, water outlet 62, and strip spray nozzle 13. This structure is used to prevent solid particles from entering and clogging the water pipe.
[0025] In this embodiment, an isolation net 8 is vertically installed between the two side plates 2, and a liftable basket 9 is installed between the side plates 2. One side of the liftable basket 9 is attached to the isolation net 8, and a lifting mechanism 10 for the liftable basket is provided on the support plate 12. When the gate is opened to allow water to flow, the isolation net 8 can isolate garbage and aquatic plants, thereby reducing environmental pollution and preventing garbage and aquatic plants from sticking to the gate 3 and the side plates 2 and affecting the opening and closing of the gate 3. Furthermore, the garbage and aquatic plants stuck to the isolation net 8 can be lifted and removed by raising and lowering the liftable basket 9.
[0026] In this embodiment, guide plates 91 are provided on both sides of the lifting basket 9. Parallel first guide grooves 92 and second guide grooves 93 are provided on the guide plates 91. Guide posts 22 extending into the first guide grooves 92 and second guide grooves 93 are provided side by side on the side plate 2. Bending grooves 94 are provided at the bottom of the first guide grooves 92 and second guide grooves 93. An arc groove 95 is provided below the bending groove 94 at the bottom of the first guide groove 92, which surrounds the bottom end of the bending groove 94 at the bottom of the second guide groove 93. An intermediate plate 14 is provided between the base 1 and the support plate 12. An opening 15 is provided on the intermediate plate 14 for the lifting basket 9 to pass through. A garbage storage basket 16 is provided on the side of the opening 15 near the lifting basket 9. The lifting basket lifting mechanism 10 includes a second winch. The steel cable on the second winch is obliquely connected to the lifting basket 9 from the side of the garbage storage basket 16. A connecting rod is fixed between the two guide plates 91, and the end of the steel cable is fixed to the connecting rod. The lifting mechanism 10 provides an upward pulling force via a steel cable. When the steel cable of the lifting mechanism 10 is wound up, the guide column 22 guides the lifting basket 9. The lifting basket 9 first rises vertically. After the guide column 22 passes through the bending groove 94, the lifting basket 9 moves a distance away from the isolation net 8 and continues to rise. When the guide column 22 in the second guide groove 93 reaches the bottom of the second guide groove 93, the guide column 22 in the first guide groove 92 reaches the upper end of the arc groove 95. When the steel cable continues to be wound up, the lifting basket 9 will rotate around the guide column 22 at the bottom of the second guide groove 93, and the water plants and garbage on the lifting basket 9 will be poured into the garbage storage basket 16 for collection.
[0027] In this embodiment, a float 96 is provided on the guide plate 91. The float 96 is an airbag with a positioning plate on one side. The lifting basket 9 is suspended on the water surface by the buoyancy of the float 96. A first touch switch 97 is provided on the base at the bottom of the lifting basket 9, and a second touch switch 98 is provided on the top of the garbage storage basket 16. When the bottom of the lifting basket 9 presses down on the first touch switch 97, the second winch winds up the steel cable to lift the lifting basket 9. When the lifting basket 9 reaches the top and flips to contact the second touch switch 98, the second winch releases the steel cable to lower the lifting basket 9. See also Figure 9The lifting basket 9 is suspended on the water surface by the buoyancy of the float 96. When the aquatic plants and garbage are blocked and accumulated by the isolation net 8, they will exert downward pressure on the lifting basket 9. When the pressure reaches a certain value, the lifting basket 9 will contact the first touch switch 97. The second winch will wind up the steel cable to lift the lifting basket 9 until the aquatic plants and garbage on the lifting basket 9 are poured into the garbage storage basket 16. When the aquatic plants and garbage on the lifting basket 9 are poured into the garbage storage basket 16, the lifting basket 9 will contact the second touch switch 98. At this time, the second winch will release the steel cable to lower the lifting basket 9. The lifting basket 9 continues to be suspended on the water surface by the buoyancy of the float 96. With this structure, when the amount of garbage and aquatic plants reaches a certain amount, the aquatic plants and garbage on the lifting basket 9 can be automatically dumped into the garbage storage basket 16 for collection without the need for special personnel to supervise, and it is more energy-efficient.
[0028] In this embodiment, a waist hole 99 is vertically provided on the guide plate 91, and a screw hole is provided on the float 96. Bolts are inserted through the waist hole 99 to fix the float 96 to the guide plate 91. The suspension height of the lifting basket 9 can be adjusted by adjusting the fixed height of the float 96 on the guide plate 91. This structure allows adjustment of the position of the float 96 on the guide plate 91, thereby adjusting the suspension position of the lifting basket 9 according to the water level. This can adapt to different water level heights and also adjust the distance between the bottom of the lifting basket 9 and the first touch switch 97 as needed, thereby adjusting the storage amount of water plants and garbage in the lifting basket 9 each time.
[0029] The above are merely preferred embodiments of the present invention.
