AI Technical Summary
In existing water conservancy projects, the gate structure is deformed at the bottom due to water pressure when the gate is raised, which affects its service life.
The gate adopts a sliding groove and slider structure within the gate frame, combined with single-screw and twin-screw hoists. The pressure of water flow on the lower end of the gate is reduced by lifting baffles and limit rods, and stability is improved by using rectangular through holes and sealing rubber strips.
It effectively reduces the pressure of water flow on the lower end of the gate, reduces deformation, and improves the service life of the gate.

The lifting baffles are arranged vertically opposite each other, and connecting rods are fixedly installed on the left and right sides between the two vertically opposite lifting baffles. The lower front part of the two upper lifting baffles is integrally provided with a mounting protrusion. A limit rod is fixedly installed on the upper part of each mounting protrusion, and both limit rods penetrate the mounting plate.

Detailed Implementation
[0021] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 As shown, a gate structure for a water conservancy project includes a gate frame 1. Sliding grooves 2 are provided on both inner walls of the gate frame 1. A single screw hoist 3 is fixedly installed on the upper part of the gate frame 1. A first screw 4 is installed inside the single screw hoist 3. A gate baffle assembly 6 and a lifting baffle assembly 5 are provided inside the gate frame 1.
[0022] In this implementation plan, in conjunction with the appendix Figure 3 As shown, the gate baffle assembly 6 includes a gate baffle 61, with sliders 62 fixedly installed on the left and right sides of the gate baffle 61 respectively. The gate baffle 61 has rectangular through holes 63 in a matrix shape inside. A base plate 65 is integrally provided on the lower front side of the gate baffle 61, and a screw mounting seat 64 is integrally provided on the upper part of the gate baffle 61.
[0023] In this implementation plan, in conjunction with the appendix Figure 2 As shown, the lifting baffle assembly 5 includes a mounting plate 51. A double-screw gate hoist 52 is fixedly mounted on the upper part of the mounting plate 51. A second screw 57 is mounted at each of the two screw mounting points of the double-screw gate hoist 52. A lifting baffle 53 is mounted on the lower part of each second screw 57. The lifting baffles 53 are arranged vertically opposite each other, and connecting rods 54 are fixedly mounted on the left and right sides between the two vertically opposite lifting baffles 53. An integral mounting protrusion 55 is provided on the lower front side of the two upper lifting baffles 53. Each mounting protrusion 55 has an upper... Each part is fixedly installed with a limit rod 56, and both limit rods 56 penetrate the mounting plate 51. Before opening the gate baffle 61, the second screw 57 is raised by the twin screw hoist 52. The second screw 57 raises the lifting baffle 53. At this time, the water flow can be discharged through the rectangular through hole 63 first. Then the gate baffle 61 is raised, which can reduce the pressure of the water flow on the lower end of the gate baffle 61, reduce the deformation of the lower part of the gate baffle 61, and improve the service life. When the lifting baffle 53 is raised, the limit rod 56 rises along the mounting plate 51 and plays a limiting role for the lifting baffle 53.
[0024] In this embodiment, specifically, the screw mounting base 64 is installed at the lower end of the first screw 4.
[0025] In this embodiment, specifically, the two sliders 62 are slidably disposed in the slide grooves 2 provided on both sides.
[0026] In this embodiment, specifically, the mounting plate 51 is fixedly installed on the upper part of the gate baffle 61.
[0027] In this embodiment, specifically, the number of lifting baffles 53 is matched with the number of rectangular through holes 63.
[0028] In this embodiment, specifically, the lifting baffle 53 is positioned directly opposite the front of the rectangular through hole 63.
[0029] In this embodiment, specifically, a sealing rubber strip is fixedly provided on the rear side of each of the lifting baffles 53, and the sealing rubber strip serves to seal the lifting baffle 53 with the gate baffle 61.
[0030] Working principle
[0031] In this utility model, the single screw hoist 3 and the twin screw hoist 52 are connected to an external control device, and the gate frame 1 is installed at the gate position. When the single screw hoist 3 drives the first screw 4 to rise, the slider 62 moves along the slide groove 2, so that the gate baffle 61 rises more stably.
[0032] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
