Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a protective device for gate slots in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Nowadays, most water conservancy projects use gate slots and gates in combination to release and stop water.

[0003] Traditional gates experience continuous friction with their gate slots during raising and lowering, leading to wear on both and eventually gaps. These gaps not only exacerbate wear but also cause the gate to sway during operation, increasing safety hazards. Utility Model Content

[0004] In existing technologies, traditional gates and gate slots experience continuous friction during lifting and lowering, leading to wear and tear on both and eventually gaps. These gaps not only exacerbate wear but also cause the gate to sway during lifting and lowering, increasing safety hazards. This invention provides a gate slot protection device for hydraulic engineering projects.

[0005] The technical solution adopted by this utility model is: a gate slot protection device for water conservancy projects, including a mounting frame. The mounting frame has slots on both sides and the bottom of its inner wall. A gate body is installed inside the mounting frame. A first motor is fixedly installed on the upper side of the mounting frame. A winding roller is fixedly installed at the output end of the first motor. Two symmetrical pull ropes are wound around the surface of the winding roller. One end of each pull rope passes through the top of the mounting frame and is fixedly connected to both sides of the upper surface of the gate body. Protective components are installed on both sides of the gate body to facilitate stable lifting of the gate body. The protective components include sliding plates fixedly installed on both sides of the gate body. The combination of the first motor and the winding roller realizes the automatic lifting and lowering of the gate body, improving the convenience and efficiency of operation. The design of the protective components and sliding plates ensures the stability of the gate body during the lifting and lowering process and reduces damage caused by shaking.

[0006] Furthermore, the sliding plates on both sides are slidably connected to the slots on both sides, and each side of the sliding plate is provided with a mounting frame. The mounting frame passes through one side surface of the sliding plate and is slidably connected to the sliding plate. Multiple pulleys are rotatably connected to the upper and lower sides of the mounting frame. Fixed rods are fixedly installed on both sides of the inner wall of the slots on both sides, and the multiple pulleys are slidably connected to the fixed rods. The sliding connection between the sliding plate and the slot, as well as the cooperation between the pulleys and the fixed rods, ensures the precise guidance of the gate during the lifting and lowering process, avoiding the risk of deviating from the track. The sliding connection between the pulleys and the fixed rods greatly reduces frictional resistance, making the gate lifting and lowering smoother and reducing energy consumption.

[0007] Furthermore, a second motor is fixedly installed above the sliding plate, and a connecting rod is fixedly installed at the output end of the second motor. A first bevel gear is fixedly installed at the bottom end of the connecting rod, and a second bevel gear meshes with both sides of the first bevel gear. A threaded rod is fixedly installed on one side of each of the two second bevel gears. The threaded rod passes through the middle of one side of the mounting frame and is threadedly connected to the mounting frame. By driving the threaded rod to rotate through the second motor, the mounting frame can be moved, thereby compensating for the gap between the pulley and the fixed rod caused by wear and ensuring the long-term stable operation of the equipment.

[0008] Furthermore, the sliding plate has limit grooves on both the upper and lower sides, and a limit plate is fixedly installed on one side of each of the mounting frames. The limit plate is slidably connected to the limit groove, which can limit the mounting frame.

[0009] Furthermore, a buffer pad is fixedly installed inside the bottom slot. The buffer pad can effectively absorb the impact force when the gate descends to the bottom, reduce damage to the gate and the mounting bracket, and extend the service life of the equipment.

[0010] Furthermore, sealing strips are fixedly installed on the edges of the three slots. The sealing strips can effectively prevent water and impurities from entering the slots, protect the normal operation of the sliding plate and pulley, avoid failures caused by corrosion and wear, and reduce maintenance frequency.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model ensures the stability of the gate body during lifting and lowering through the design of protective components, reducing damage caused by shaking. It solves the problem of continuous friction between the traditional gate and gate slot during lifting and lowering, leading to wear on both and eventually gaps. These gaps not only further exacerbate wear but also cause the gate to shake during lifting and lowering, increasing safety hazards. Attached Figure Description

[0022] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below.

[0023] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a gate slot protection device for water conservancy projects.

[0024] The specific technical solution includes a mounting frame 1. The mounting frame 1 has slots 2 on both sides and bottom of its inner wall. The mounting frame 1 houses a gate body 3. A first motor 4 is fixedly installed on the upper side of the mounting frame 1. A winding roller 5 is fixedly installed at the output end of the first motor 4. Two symmetrical pull ropes 6 are wound around the surface of the winding roller 5. One end of each pull rope 6 passes through the top of the mounting frame 1 and is fixedly connected to both sides of the upper surface of the gate body 3. Protective components 7 are installed on both sides of the gate body 3 to facilitate stable lifting of the gate body 3. The protective components 7 include sliding plates 701 fixedly installed on both sides of the gate body 3. The output end of the first motor 4 drives the winding roller 5 to rotate. When the winding roller 5 rotates, the two symmetrical pull ropes 6 wound around its surface are wound up and down accordingly. One end of the pull rope 6 is fixedly connected to both sides of the upper surface of the gate body 3. As the pull rope 6 is pulled in and out, the gate body 3 moves up and down in the slot 2 of the mounting frame 1, thereby realizing the opening or closing of the gate body 3. The design of the protective component 7 ensures the stability of the gate body 3 during the lifting process and reduces the damage caused by shaking.

[0025] Reference Figures 1 to 6 As shown, the two sliding plates 701 are slidably connected to the two slots 2 respectively. Each side of the sliding plate 701 is provided with a mounting frame 702, which penetrates one side surface of the sliding plate 701 and is slidably connected to it. Multiple pulleys 703 are rotatably connected to the upper and lower sides of the mounting frame 702. Fixing rods 704 are fixedly installed on both sides of the inner wall of the two slots 2, and the multiple pulleys 703 are slidably connected to the fixing rods 704. A second motor 705 is fixedly installed above the sliding plate 701. A connecting rod 706 is fixedly installed at the output end of the second motor 705. A first bevel gear 707 is fixedly installed at the bottom end of the connecting rod 706. Second bevel gears 708 mesh on both sides of the first bevel gear 707. Threaded rods 709 are fixedly installed on one side of each of the two second bevel gears 708, penetrating the middle of one side of the mounting frame 702 and connecting to it. The mounting frame 702 is threaded. Limiting grooves 710 are provided on both the upper and lower sides of the sliding plate 701. Limiting plates 711 are fixedly installed on one side of the mounting frames 702 on both sides. The limiting plates 711 are slidably connected to the limiting grooves 710. Through the sliding connection between the sliding plate 701 and the groove 2, the stable lifting and lowering of the gate body 3 is ensured. The design of the pulley 703 and the fixed rod 704 further reduces the frictional resistance, making the lifting and lowering of the gate body 3 smoother. The output end of the second motor 705 drives the connecting rod 706 and the first bevel gear 707 to rotate, which in turn drives the second bevel gears 708 on both sides to rotate simultaneously, causing the threaded rods 709 on both sides to rotate, thereby pushing the mounting frames 702 on both sides to move to both sides. This avoids wear on the pulley 703 and the fixed rod 704 after long-term use, which would cause the gap between the pulley 703 and the fixed rod 704 to be too large, affecting the normal opening and closing of the gate body 3.

[0026] Reference Figure 1 and Figure 2 As shown, a buffer pad 8 is fixedly installed inside the bottom slot 2, and a sealing strip 9 is fixedly installed on the edge of each of the three slots 2. When the gate body 3 descends to the bottom, the buffer pad 8 can absorb the impact force and reduce the damage to the gate and the mounting bracket 1. The sealing strip 9 can prevent water and impurities from entering the inside of the slot 2, ensuring the smooth opening and closing of the gate body 3.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, when it is necessary to raise or lower the gate body 3, the first motor 4 starts, and the output end of the first motor 4 drives the winding roller 5 to rotate. When the winding roller 5 rotates, the two symmetrical pull ropes 6 wound on its surface are wound and unwound accordingly. One end of the pull rope 6 is fixedly connected to both sides of the upper surface of the gate body 3. As the pull rope 6 is wound and unwound, the gate body 3 moves up and down in the slot 2 of the mounting frame 1, thereby realizing the opening or closing of the gate body 3. The sliding plates 701 on both sides of the gate body 3 are slidably connected to the slots 2 on both sides of the inner wall of the mounting frame 1 to ensure that the gate body 3 moves smoothly along the predetermined track. Multiple pulleys 703 are rotatably connected to the upper and lower sides of the mounting frame 702 on both sides of the sliding plate 701. The pulleys 703 are slidably connected to the fixed rods 704 on both sides of the inner wall of the slot 2 to reduce frictional resistance and make the gate body move smoothly. 3. The lifting and lowering are smoother. The output end of the second motor 705 drives the connecting rod 706 to rotate. The first bevel gear 707 at the bottom of the connecting rod 706 meshes with the second bevel gears 708 on both sides, causing the second bevel gears 708 on both sides to rotate simultaneously. The second bevel gears 708 drive the threaded rod 709 to rotate. The threaded rod 709 passes through the middle of one side of the mounting frame 702 and is threadedly connected to the mounting frame 702. The rotation of the threaded rod 709 pushes the mounting frame 702 to slide along the limiting groove 710. The limiting plate 711 is slidably connected to the limiting groove 710 to ensure the stable movement of the mounting frame 702. The second motor 705 drives the mounting frame 702 to move to both sides, which can compensate for the wear gap between the pulley 703 and the fixed rod 704 due to long-term use, and ensure the normal opening and closing of the gate body 3.
