Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering gates, specifically a lifting water conservancy engineering gate for water conservancy projects. Background Technology

[0002] A lifting gate for water conservancy projects consists of a steel gate plate, a hydraulic lifting system, and guide rails on both sides. The gate plate is driven by a hydraulic cylinder to rise and fall vertically along the guide rails to open and close the waterway. It is equipped with rubber seals to prevent leakage and a water level sensor linkage control system. The height can be adjusted automatically or manually. It is suitable for reservoirs and rivers, and can accurately control the flow rate, prevent floods and drain water. It also has the properties of water pressure resistance and corrosion resistance to ensure the safe operation of water conservancy projects. It is easy to operate and flexible in adjustment.

[0003] A search revealed that Chinese patent CN221589509U discloses a lifting-type hydraulic engineering gate for water conservancy projects. This patent describes a method where, after the gate body is raised and opened, a barrier net blocks impurities and floating debris in the water flow, facilitating their unified treatment. When floating debris impacts the barrier net, the net compresses a buffer block through the impact force. The buffer block then moves a truncated cone body into the buffer groove. Because the maximum diameter of the truncated cone body is larger than the inner diameter of the buffer groove, the resistance experienced by the truncated cone body gradually increases, simultaneously compressing the buffer spring. Therefore, through the reaction of the buffer spring and the elasticity of the buffer block itself, the impact force of the floating debris is buffered, preventing damage to the barrier net. This technical solution solves the problem that existing lifting-type hydraulic engineering gates are unable to filter and block impurities and floating debris in the water flow, easily causing impurities and floating debris to move with the water flow, which is not conducive to the unified treatment of waste.

[0004] Although the current solution can filter impurities with the barrier net and resist impact with the buffer block and spring, it has obvious shortcomings. Its buffer structure is only set around the barrier net, which is insufficient to protect the gate body. When water flow impacts or debris collides with the gate, the gate is prone to deformation and damage due to direct force, which affects the opening and closing function and service life. In order to solve this technical problem, this utility model proposes a lifting gate for water conservancy projects. Utility Model Content

[0006] Although the current solution can filter impurities with the barrier net and resist impact with the buffer block and spring, it has obvious shortcomings.

In order to solve this technical problem, this utility model proposes a lifting gate for water conservancy projects.

[0014] (III) Beneficial Effects

[0015] This utility model provides a lifting gate for water conservancy projects. It has the following beneficial effects:

[0016] (1) When the gate is impacted by external force, the buffer arc plate is squeezed and rotated through the positioning rod one. The rotating plate pushes the connecting plate around the positioning rod two. The connecting plate slides along the connecting rod in the slide groove one, compressing or stretching the spring. The damping rod absorbs the impact force. The slider slides in the slide groove two to ensure the stability of the connecting plate. This combination solves the problem of poor impact resistance and easy damage due to uneven force of traditional gates. It changes the situation of insufficient protection and stability. Through multi-component linkage buffering and precise guidance, the gate's impact resistance and operational stability are improved, and its service life is extended. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A lifting gate for water conservancy projects, comprising a water channel 1, a gate 3 installed inside the water channel 1, a pair of sliding grooves 4 opened inside one side of the gate 3, a pair of connecting rods 5 fixedly connected inside each sliding groove 4, a spring 6 sleeved on the outer wall of each connecting rod 5, a connecting plate 7 slidably connected to the outside of each connecting rod 5, a rotating plate 12 installed outside the connecting plate 7, a buffer arc plate 14 installed at the other end of the rotating plate 12, and a damping rod 13 fixedly connected to the inner wall of the buffer arc plate 14. The other end of the damping rod 13 is fixedly connected to the outer wall of the gate 3. A connecting seat 2 10 is fixedly connected to the outer wall of the connecting plate 7. A positioning rod 2 11 is fixedly connected to one end of the rotating plate 12. The rotating plate 12 is rotatably connected to the inside of the connecting seat 2 10 through the positioning rod 2 11. Connecting seats 1 8 are fixedly connected to both outer walls of the buffer arc plate 14. A positioning rod 1 9 is fixedly connected to the other end of the rotating plate 12. The rotating plate 12 is rotatably connected to the inside of the positioning rod 1 9 through the positioning rod 1 9. The bottom outer wall of the gate 3 is fixedly connected to... A pair of inclined blocks 17 are connected. Slider blocks 15 are fixedly connected to both the upper and lower sides of the connecting plate 7. Slider groove 16 is opened inside both the upper and lower sides of the slide groove 1, and the slider 15 is slidably connected inside the slide groove 16. A fixed bracket 2 is fixedly connected to the outer wall of the water channel 1. A motor 18 is fixedly connected to the top of the fixed bracket 2. A rotating rod 19 is fixedly connected to the output end of the motor 18. A winding rod 20 is fixedly connected to the outer walls of both ends of the rotating rod 19. A rope 21 is wound around the outside of the winding rod 20. The other end of the rope 21 is fixedly connected to... On the outer wall of the gate 3, a pair of fixed pulleys 26 are rotatably connected to the upper outer wall of the fixed bracket 2, and the rope 21 is slidably connected to the outer wall of the fixed pulleys 26. A protective shell 25 is fixedly installed on the outside of the winding roller 20. A pair of limiting rods 27 are fixedly connected between the water channel 1 and the fixed bracket 2. A pair of connecting blocks 23 are fixedly connected to the outer wall of the other side of the gate 3. A pair of wheels 24 are rotatably connected inside each connecting block 23. Grooves 22 are opened on both sides of the limiting rods 27, and the wheels 24 are slidably connected inside the grooves 22.

[0025] Motor 18 starts, driving rotating rod 19 to rotate. Rotating rod 19 drives winding roller 20 to rotate synchronously, performing winding or releasing operation on rope 21. Under the auxiliary guidance of fixed pulley 26, the gate 3 is raised and lowered inside the water channel 1. When the gate 3 encounters water flow impact, collision with debris, etc. during the raising and lowering process, buffer arc plate 14 is the first to contact and bear the force. The impact force causes buffer arc plate 14 to squeeze damping rod 13, and at the same time, it drives rotating plate 12 to rotate around positioning rod 19 and positioning rod 21. Rotating plate 12 pushes... The moving connecting plate 7 slides along the connecting rod 5 in the first slide groove 4. During this process, the spring 6 is compressed or stretched, thereby absorbing and buffering the impact force. The slider 15 slides inside the second slide groove 16 to ensure the stability of the connecting plate 7 when it moves. The wheel 24 slides in the groove 22 of the limit rod 27 to help the gate 3 maintain a vertical lifting state. The inclined block 17 can reduce the accumulation of debris at the bottom of the gate 3. Through the cooperation of these components, the lifting and buffering protection process of the gate 3 is more stable and efficient, which can be adapted to the use needs of water conservancy scenarios.

[0026] Working principle: When the motor 18 starts, it drives the rotating rod 19 to rotate, and the winding roller 20 on the rotating rod 19 rotates accordingly, winding or releasing the rope 21. With the assistance and guidance of the fixed pulley 26, the gate 3 is raised and lowered along the water channel 1. When the gate 3 is raised and lowered, if it encounters water flow impact or debris, the buffer arc plate 14 will contact it first. The impact force causes the buffer arc plate 14 to squeeze the damping rod 13, while driving the rotating plate 12 to rotate around the positioning rod 9 and the positioning rod 11. The rotating plate 12 pushes the connecting plate 7 to slide along the connecting rod 5 in the sliding groove 4. The spring 6 is compressed or stretched to absorb the impact force. The slider 15 slides in the sliding groove 16 to ensure the stable movement of the connecting plate 7. The wheel 24 slides in the groove 22 of the limit rod 27 to assist the gate 3 in vertical raising and lowering. The inclined block 17 can reduce the accumulation of debris at the bottom of the gate 3. Through the cooperation of these components, the raising and lowering of the gate 3 and the buffer protection are more stable and efficient, and are suitable for use in water conservancy scenarios.
