[0002] The gate hoist is a key component in water conservancy facilities, integrating precision design and powerful functions. The gate hoist is responsible for accurately controlling the opening and closing of the gate, achieving scientific regulation and precise control of water flow. Whether it is used for flood control and drainage, farmland irrigation, or urban water supply and hydropower generation, the gate hoist plays an indispensable and important role;

[0003] In the prior art, the opening and closing of facilities such as weirs and gates is achieved by using a gate hoist to provide power for the up and down movement of a transmission screw. In order to avoid direct friction between the sealing strip and the gate, radial displacement of the gate plate is used to make the gate plate and the gate close to each other for sealing. In the process of the gate plate sliding down the track of the outer frame and moving radially, a certain angle of inclination may be generated in the vertical direction. Therefore, the gate plate cannot maintain its own verticality when it slides to the bottom, thereby causing a gap between the sealing strip and the gate, thereby reducing the sealing effect of the sealing strip.

[0004] Therefore, it is urgent to improve the gate of the hoist to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a gate of a gate hoist, when the gate plate slides down through the track of the outer frame and moves radially, the upper hook member follows the slide and is hooked with the upper fastener at the upper end of the gate, so as to ensure that the position of the upper end of the gate plate does not deviate, when the gate plate slides down to the bottom, its bottom end abuts against one end of the L-shaped fastener on the lower hook member, and the upper end of the transmission L-shaped fastener buckles the reinforcing ribs on the gate plate, thereby ensuring that the top and bottom ends of the gate plate are in the same vertical plane, thereby greatly improving the sealing performance of the sealing strip.

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1 - Figure 5 As shown, a gate hoist provided in this embodiment comprises an outer frame 1 and a gate plate 2 slidably arranged inside the outer frame 1, the outer frame 1 is used to provide a track for the gate plate 2 to slide down, a rod connecting member 3 is fixedly arranged on the upper end of the gate plate 2, the rod connecting member 3 is used to drive the gate plate 2 to slide to realize the opening and closing function, an upper hook 4 is fixedly installed on the gate plate 2, and the upper hook 4 is arranged on both sides of the rod connecting member 3, a gate 5 is fixedly arranged below the outer frame 1 corresponding to the gate plate 2, an upper fastener 6 is fixedly installed on the upper end of the gate 5, the upper fastener 6 corresponds to the upper hook 4, and when the gate plate 2 slides, the upper hook 4 will be hooked with the upper fastener 6 to fix the top of the gate plate 2;

[0025] One end of the upper hook 4 close to the upper fastener 6 is an inclined surface, and two lower hooks 7 are fixedly installed at the bottom end of the gate plate 2. The lower hook 7 corresponds to the bottom end of the gate plate 2. An L-shaped fastener 8 is rotatably provided on the lower hook 7. When the gate plate 2 slides down to the bottom, its bottom end abuts against one end of the L-shaped fastener 8 on the lower hook 7, and the upper end of the transmission L-shaped fastener 8 buckles the reinforcing rib on the gate plate 2, thereby fixing the bottom end of the gate plate 2. The upper hook 4 and the lower hook 7 are respectively located on both sides of the vertical plane where the gate plate 2 is located. During the sliding process of the gate plate 2, the sealing rubber or sealing strip is pressed against the gate 5 through the inclined surface of the upper hook 4 and the upper fastener 6;

[0026] Among them, when the gate plate 2 slides down through the track of the outer frame 1 and moves radially, the upper hook 4 follows and slides down and is hooked with the upper fastener 6 at the upper end of the gate 5, which can ensure that the position of the upper end of the gate plate 2 does not shift. When the gate plate 2 slides down to the bottom, its bottom end is against one end of the L-shaped fastener 8 on the lower hook 7, and the upper end of the transmission L-shaped fastener 8 buckles the reinforcing ribs on the gate plate 2, thereby ensuring that the top and bottom ends of the gate plate 2 are in the same vertical plane, thereby greatly improving the sealing of the sealing strip.

[0027] Further, such as Figure 1 and Figure 2 As shown, the rod connector 3 is internally rotatably connected with a screw rod 9, which is used to drive the gate plate 2 to slide through the rod connector 3. Through the rotational connection between the rod connector 3 and the screw rod 9, the rotational movement of the screw rod 9 can be converted into the linear sliding of the gate plate 2. This transmission method can achieve precise control of the movement of the gate plate 2, thereby accurately adjusting the opening size of the gate and accurately controlling the water flow. At the same time, it can also more effectively transfer the energy of the power source to the gate plate 2, achieve rapid and stable sliding of the gate plate 2, and ensure the stable operation of the power mechanism.

[0028] Furthermore, Figure 1 As shown, a circular water outlet 10 is opened in the middle of the gate 5, and the radius of the circular water outlet 10 is smaller than the side length of the gate plate 2. When the gate plate 2 is fully closed, the gate plate 2 can completely cover the circular water outlet 10. Since the side length of the gate plate 2 is greater than the radius of the circular water outlet 10, the contact surface between the gate plate 2 and the periphery of the water outlet is larger, and it is easier to form a good seal and reduce water leakage.

[0029] In addition, the design of the circular water outlet 10 makes the water pressure relatively concentrated in the circular area when water flows through, and the gate plate 2 can effectively shield and control this concentrated force area. This concentrated force structure helps to improve the stability and strength of the entire gate system and reduce structural deformation or damage caused by water flow impact.

[0030] Further, if Figure 1 - Figure 5 As shown, a shaft 11 is rotatably provided on the lower hook 7, the shaft 11 penetrates the lower hook 7 and extends to both sides of the lower hook 7 and the L-shaped fastener 8, the L-shaped fastener 8 is rotatably provided on one side of the lower hook 7 through the shaft 11, the shaft 11 penetrates the lower hook 7 and the L-shaped fastener 8, so that the L-shaped fastener 8 can rotate relative to the lower hook 7 around the shaft 11, and this rotation connection mode provides a basis for the movement of the L-shaped fastener 8, so that the entire structure can realize corresponding actions under different working conditions;

[0031] At the same time, if Figure 4 and Figure 5As shown, a hanging column 12 is fixedly installed on the side of the lower hook member 7 away from the L-shaped fastener 8, and a tension spring 13 is hung on the hanging column 12. A pull rod 14 is fixedly installed on the end of the shaft rod 11 away from the L-shaped fastener 8, and the end of the pull rod 14 away from the shaft rod 11 is fixedly connected to the tension spring 13; the tension spring 13 hung on the hanging column 12 is connected to the pull rod 14, and when the L-shaped fastener 8 rotates under the action of an external force, the tension spring 13 can provide a restoring force so that the L-shaped fastener 8 can quickly return to the initial position. When the gate plate 2 slides downward, the bottom end contacts with one end of the L-shaped fastener 8, and drives the L-shaped fastener 8 to rotate and lock the gate plate 2. When the gate plate 2 slides upward, the tension spring 13 drives the L-shaped fastener 8 to reset, thereby improving the stability of the gate plate 2 and realizing the automatic locking function of the gate plate 2, which is more convenient and quick to use;

[0032] In addition, if Figure 5 As shown, a waterproof cover 15 is fixedly provided on one side of the lower hook member 7, and the shaft rod 11, the hanging column 12, the tension spring 13 and the pull rod 14 are all arranged inside the waterproof cover 15. The waterproof cover 15 cooperates with the sealed bearing on the shaft rod to prevent the shaft rod 11, the hanging column 12, the tension spring 13 and the pull rod 14 from directly contacting with water, thereby reducing the probability of rust, thereby greatly extending the service life of the L-shaped fastener 8.

[0033] like Figure 1 - Figure 5 As shown, the principle of the gate hoist provided in this embodiment is as follows:

[0034] The outer frame 1 is used to provide a track for the gate plate 2 to slide down. A rod connecting member 3 is fixedly provided on the upper end of the gate plate 2. The rod connecting member 3 is used to drive the gate plate 2 to slide to realize the opening and closing function. Upper hooks 4 are fixedly provided on both sides of the rod connecting member 3. A gate 5 is fixedly provided below the outer frame 1 corresponding to the gate plate 2. An upper fastener 6 is fixedly installed on the upper end of the gate 5. The upper fastener 6 corresponds to the upper hook 4. When the gate plate 2 slides, the upper hook 4 will be hooked with the upper fastener 6 to fix the top of the gate plate 2, which can ensure the position of the upper end of the gate plate 2 No deviation; two lower hooks 7 are fixedly installed on the bottom end of the gate plate 2, and the lower hooks 7 correspond to the bottom end of the gate plate 2. An L-shaped fastener 8 is rotatably provided on the lower hook 7. When the gate plate 2 slides down to the bottom, its bottom end is against one end of the L-shaped fastener 8 on the lower hook 7, and the upper end of the transmission L-shaped fastener 8 buckles the reinforcing ribs on the gate plate 2, thereby fixing the bottom end of the gate plate 2. The upper hook 4 and the lower hook 7 are respectively located on both sides of the vertical plane where the gate plate 2 is located, thereby ensuring that the top and bottom ends of the gate plate 2 are in the same vertical plane.
