Description

Technical Field

[0001] This utility model belongs to the field of water conservancy gate technology, and specifically relates to a lifting water conservancy gate. Background Technology

[0002] Hydraulic gates, as core facilities for regulating water levels and controlling water flow, are widely used in water conservancy projects such as flood control and drainage, farmland irrigation, and urban water supply. Through opening and closing operations, they enable water volume management in rivers, reservoirs, and other water bodies, playing a vital role in ensuring the stable operation of water conservancy systems and promoting regional economic development. With the increasing demands for intelligent and environmentally friendly water conservancy projects, modern hydraulic gates not only need to meet basic water-blocking functions but also require comprehensive capabilities such as silt removal and garbage interception to adapt to the management needs of complex aquatic environments.

[0003] Existing water gates are prone to silt accumulation at the bottom after long-term use, which affects the smoothness of opening and closing and the sealing performance. It can also damage the sealing structure between the gate and the frame, leading to an increase in leakage rate and even equipment failure. At the same time, they are not capable of intercepting floating garbage in the water. Most gates are not equipped with dedicated interception devices and need to be cleaned manually or with additional salvage equipment, which is inefficient and costly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lifting hydraulic gate.

[0005] To achieve the above objectives, this utility model provides a lifting hydraulic gate, comprising a frame, a top plate connected to the upper end of the frame, a lifting device connected to the lower middle of the top plate, two lifting rods slidably connected inside the lifting device, the upper ends of the two lifting rods extending through to the upper end of the top plate, and mounting buckles connected to the lower ends of the two lifting rods. The gate body is connected to the lower ends of the two mounting buckles. The gate body slides on both sides of the inner wall of the frame, and mud-blocking components are evenly connected to one side of the frame. A retrieval component is connected to the lower part of one side of the gate body.

[0006] In the above technical solution, the mud-blocking assembly further includes a rotating seat, and the number of rotating seats is four. One side of each of the multiple rotating seats is connected to one side of the frame. The upper ends of two of the rotating seats are connected to rotating rods. The upper ends of the two rotating rods extend through to the top of the other two rotating seats. The upper ends of the two rotating rods are connected to a first motor. The outer walls of the two first motors are connected to protective frames. One side of each of the two protective frames is connected to one side of the frame.

[0007] In the above technical solution, further, a rotating block is connected to the lower part of the outer wall of each of the two rotating rods, a mudguard is connected to one end of each of the two rotating blocks, and a water outlet is opened on the upper part of one side of each of the two mudguards, and the water outlet is square in shape.

[0008] In the above technical solution, further, a pusher plate is connected to the lower part of one side of the two mudguards, the shape of one side of the pusher plate is inclined, and the shape of the lower end of the pusher plate is adapted to the lower end of the mudguard.

[0009] In the above technical solution, the salvage component further includes a salvage net, one end of which is connected to the lower part of one side of the gate body, and a collection frame is connected to one end of the salvage net. The collection frame is located on one side of two mudguards. Slide plates are connected to the middle of both sides of the frame. The upper ends of the two slide plates are respectively connected to the lower side of the protective frame, and the lower ends of the two slide plates are respectively connected to the upper side of two rotating seats. A second motor is connected to the lower part of both sides of the lifting device.

[0010] In the above technical solution, further, pull plates are connected to both sides of the upper end of the collection frame. The pull plates are in the shape of an inverted L-shape. A slider is connected to the upper part of one side of each of the two pull plates. The two sliders slide on one side of each of the two slide plates. The sliders are in the shape of an inverted T-shape. A groove is provided on the slide plate corresponding to the slider. The slider is located inside the groove.

[0011] In the above technical solution, the output ends of the two second motors are further connected to take-up rollers, one end of each of the two take-up rollers is rotatably connected to the lower part of one side of the two protective shells, and pull ropes are wound around the outer walls of the two take-up rollers, with the lower ends of the two pull ropes connected to the upper side of the two pull plates respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The mud-blocking assembly significantly improves the sludge removal effect through a dual mechanism of "active mud pushing + water flushing". The inclined structure of the mud pushing plate can quickly push the sludge accumulated at the bottom of the gate to both sides, avoiding the sludge accumulation that causes the gate to not close tightly or increase the opening and closing resistance. This effectively reduces the risk of equipment failure caused by sludge blockage. At the same time, the square outlet on the mud-blocking plate can balance the water pressure on both sides and reduce the resistance when the mud-blocking plate moves, thereby reducing the energy consumption and wear of the first motor and extending the service life of the equipment.

[0014] The automated operation of garbage interception and collection is achieved through the retrieval component. When the gate is opened, the retrieval net automatically unfolds as the gate body rises to form an inclined interception surface, which can efficiently intercept garbage of different sizes in the water and prevent debris such as branches and plastic bags from spreading with the water flow, effectively improving the aquatic ecological environment. After the gate rises to the set height, the second motor drives the collection frame to rise along the slide plate. The inclined guide block at the bottom smoothly guides the garbage intercepted by the retrieval net into the frame, completing the centralized collection. This process does not require real-time manual intervention, greatly reducing the manpower input for garbage cleaning. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-7 The image shows a type of lifting hydraulic gate.

[0025] Example 1

[0026] The system includes a frame 1, a top plate 2 connected to the upper end of the frame 1, a lifting device 3 connected to the middle of the lower end of the top plate 2, two lifting rods 4 slidably connected inside the lifting device 3, the upper ends of the two lifting rods 4 extending through to the upper end of the top plate 2, and mounting buckles 5 connected to the lower ends of the two lifting rods 4. Gate body 6 is connected to the lower ends of the two mounting buckles 5. The gate body 6 slides on both sides of the inner wall of the frame 1. Mud-blocking components are evenly connected to one side of the frame 1, and retrieval components are connected to the lower part of one side of the gate body 6.

[0027] The lifting device 3 on the top plate 2 serves as the power core, controlling the opening and closing of the gate. The lifting device 3 typically employs a hydraulic drive or electric push rod structure, providing stable power output and precise displacement control. Upon receiving an opening command, the hydraulic pump or motor inside the lifting device 3 drives two lifting rods 4 to slide upwards. Their upper ends penetrate the top plate 2, and their lower ends are securely connected to the gate body 6 via high-strength mounting clips 5. The mounting clips 5 employ a double-locking structure, fixed to the gate body 6 with bolts to ensure they do not detach under water pressure, thus enabling them to withstand enormous water pressure and ensure... The reliability of the connection is ensured by the tight sliding fit between the two sides of the gate body 6 and the inner wall of the frame 1 through precision-machined guide rails and sliders. Under the traction of the lifting rod 4, the gate body 6 moves smoothly upward along the inner wall of the frame 1, gradually opening the channel to allow water to flow through smoothly. When it is necessary to close the gate, the lifting device 3 controls the lifting rod 4 to slide downward. Under its own weight and the thrust of the lifting rod 4, the gate body 6 descends along the inner wall of the frame 1 until the channel is completely closed, thus achieving the water blocking function. The edge of the gate body 6 is equipped with an elastic rubber waterstop, which can effectively prevent water leakage.

[0028] Example 2

[0029] The mud-blocking assembly includes four rotating seats 7. Each of the rotating seats 7 is connected to one side of the frame 1. Two of the rotating seats 7 are connected to the upper end of rotating rods 8. The upper ends of the two rotating rods 8 extend through to the top of the other two rotating seats 7. The upper ends of the two rotating rods 8 are connected to the first motors 9. The outer walls of the two first motors 9 are connected to protective frames. One side of the two protective frames is connected to one side of the frame 1. The lower part of the outer wall of the two rotating rods 8 is connected to rotating blocks 10. One end of the two rotating blocks 10 is connected to a mud-blocking plate 11. The upper part of one side of the two mud-blocking plates 11 is provided with a water outlet 12. The water outlet 12 is square in shape. The lower part of one side of the two mud-blocking plates 11 is connected to a mud-pushing plate 13. One side of the mud-pushing plate 13 is inclined. The shape of the lower end of the mud-pushing plate 13 is adapted to the lower end of the mud-blocking plate 11.

[0030] During the gate opening process, the mudguard assembly moves synchronously with the gate. When the lifting rod 4 drives the gate body 6 to rise, the first motor 9 starts. This motor is waterproof and dustproof, suitable for hydraulic environments. The first motor 9 drives the rotating rod 8 to rotate. The rotating rod 8 drives the mudguard 11 to rotate outward around the rotating seat 7 through the rotating block 10, which increases the angle between the mudguard 11 and the frame 1. At this time, the pusher plate 13 on the lower side of the mudguard 11 swings accordingly. The pusher plate 13 is made of high-strength wear-resistant material and uses its inclined blade... The structure can efficiently push the silt accumulated on the riverbed at the bottom of the gate to both sides, preventing the silt accumulation from affecting the sealing and smooth opening and closing of the gate. The outlet 12 forms a flow channel for the water pressure on both sides of the mudguard 11, avoiding excessive pressure difference caused by water accumulation on one side. When the gate is closed, the first motor 9 drives the rotating rod 8 to rotate in the opposite direction, and the mudguard 11 rotates inward. In order to enhance the stability of the mudguard 11, a reinforced bearing is set at its rotating connection, which can withstand large torque and lateral force.

[0031] Example 3

[0032] The salvage assembly includes a salvage net 14, one end of which is connected to the lower part of one side of the gate body 6. A collection frame 15 is connected to one end of the net 14, located on one side of two mudguards 11. Slide plates 17 are connected to the middle of both sides of the frame 1. The upper ends of the two slide plates 17 are connected to the lower side of the protective frame, and the lower ends of the two slide plates 17 are connected to the upper side of two rotating seats 7. Second motors 19 are connected to the lower parts of both sides of the lifting device 3. Pull plates 16 are connected to both sides of the upper end of the collection frame 15, and the pull plates 16 are in the shape of an inverted L. The structure includes two pull plates 16 with sliders 18 connected to the upper part of one side. The two sliders 18 slide on one side of the two slide plates 17 respectively. The sliders 18 are in the shape of an inverted T-shape. The slide plates 17 have grooves corresponding to the sliders 18. The sliders 18 are located inside the grooves. The output ends of the two second motors 19 are connected to take-up rollers 20. One end of the two take-up rollers 20 is rotatably connected to the lower part of one side of the two protective shells respectively. Pull ropes 21 are wound around the outer wall of the two take-up rollers 20. The lower ends of the two pull ropes 21 are connected to the upper side of the two pull plates 16 respectively.

[0033] When the gate body 6 is opened by the lifting rod 4, the net 14 fixed at the lower part of the gate body 6 is pulled upwards simultaneously. The net 14 is used to intercept large floating objects and can capture smaller pieces of garbage. Since the collection frame 15 is initially fixed, the net 14 is gradually tightened and unfolds from the riverbed towards the water surface to form an inclined interception surface. When the water flows through the gap of the gate, the floating garbage is intercepted by the tightened net 14 and accumulates on the upstream side of the net. When the gate body 6 rises to the set height, the second motor 1... 9. Start the winding roller 20 to rotate clockwise and the winding rope 21 is pulled upward. The rope 21 pulls the pull plate 16 upward, which in turn drives the collection frame 15 to slide upward along the slide plate 17. The slider 18 slides synchronously in the groove inside the slide plate 17. The end of the net 14 is connected to the inlet of the collection frame 15 by a hinge. When the collection frame 15 rises, the tilt angle of the net 14 increases, and the garbage slides into the frame due to gravity. It is then cleaned by the staff. The collection frame 15 adopts a quick-release structure, which is convenient for quick disassembly and garbage dumping.

[0034] Working principle: When using the device, the lifting device 3 on the top plate 2 serves as the power core. When the opening command is received, the mechanical structure inside the lifting device 3 drives the two lifting rods 4 to slide upward. The upper end of the lifting rods 4 passes through the top plate 2, and the lower end drives the gate body 6 to rise through the installation buckle 5. Since the two sides of the gate body 6 are tightly slidably fitted with the inner wall of the frame 1, under the traction of the lifting rods 4, the gate body 6 rises smoothly along the inner wall of the frame 1, gradually opening the channel and allowing water to flow through. When it is necessary to close the gate, the lifting device 3 controls the lifting rods 4 to slide downward. Under the action of its own weight and the thrust of the lifting rods 4, the gate body 6 descends along the inner wall of the frame 1 until the channel is completely closed, thus achieving the water blocking function.

[0035] During the gate opening process, when the lifting rod 4 drives the gate body 6 to rise, the mud-blocking assembly installed on one side of the frame 1 operates synchronously. The first motor 9 starts and drives the rotating rod 8 to rotate. The rotating rod 8 drives the mud-blocking plate 11 to rotate outward around the rotating seat 7 through the rotating block 10. At this time, the angle between the mud-blocking plate 11 and the frame 1 increases, and the mud-pushing plate 13 on the lower side of the mud-blocking plate 11 swings accordingly. Using its inclined blade-like structure, it pushes the silt accumulated on the riverbed at the bottom of the gate to both sides, so that the silt is away from the bottom of the gate, avoiding the accumulation of silt from affecting the sealing and smoothness of the gate when it is closed. At the same time, the outlet 12 on the mud-blocking plate 11 allows water to flow through. The impact force of the water flow can help to flush the silt attached to the surface of the mud-blocking plate 11, further improving the cleaning effect. When the gate is closed, the first motor 9 drives the rotating rod 8 to rotate in the opposite direction, and the mud-blocking plate 11 rotates inward until it is close to the frame 1, forming a side seal and reducing water leakage.

[0036] The operation of the salvage component is also closely related to the lifting and lowering of the gate. When the gate body 6 is lifted and opened by the lifting rod 4, the salvage net 14 fixed at the lower part of the gate body 6 is simultaneously pulled upward. Since the initial position of the collection frame 15 is fixed, the salvage net 14 is gradually tightened and unfolds from the riverbed towards the water surface to form an inclined interception surface. When the water flows through the gate gap, the floating garbage is intercepted by the tightened salvage net 14 and accumulates on the upstream side of the net. When the gate body 6 rises to the set height, the second motor 19 starts and drives the winding roller 20 to wind up the pull rope 21. The pull rope 21 drives the collection frame 15 to rise along the slide plate 17 through the pull plate 16. The slider 18 slides synchronously in the chute, and the garbage intercepted by the salvage net 14 falls into the collection frame 15. Subsequently, the staff cleans the garbage inside the salvage net 14 and the collection frame 15.

[0037] Before the gate closes, the retrieval assembly is reset: the second motor 19 reverses to release the pull rope 21, the collection frame 15 falls back to the initial position, and then the gate body 6 begins to descend, the retrieval net 14 follows it down and folds, and part of the net sinks into the riverbed silt, thus completing a complete cycle of garbage interception and cleaning.
