[0002] A planar steel gate sluice gate mainly consists of a gate, gate piers, a base plate, a water-stopping device, and a hoisting mechanism. The gate is the key component controlling water flow; it is typically made of steel and possesses sufficient strength and rigidity to withstand water pressure. The gate piers support the gate and fix the water-stopping device, while also transferring the water pressure borne by the gate to the base plate. The base plate forms the foundation of the sluice gate, bearing the weight of the gate chamber and superstructure, as well as the water pressure, and transferring these loads to the foundation. The water-stopping device is installed between the gate, gate piers, and base plate to prevent water leakage. The hoisting mechanism controls the raising and lowering of the gate, regulating the water flow. When the gate is closed, it relies on its own... The weight of the gate and the tight contact between the water-stopping device and the gate pier and base plate form a closed water barrier; the gate bears the pressure of the upstream water, and transmits the force to the foundation through the gate pier and base plate, preventing the water flow and thus achieving the water-blocking function and maintaining the water level difference between upstream and downstream; when water needs to be discharged, the hoist is activated, and the gate is raised through the wire rope or other transmission device; as the gate rises, a water passage is formed between the gate and the base plate, and the water flows from upstream to downstream through the gate opening under the action of the water level difference between upstream and downstream; by controlling the opening height of the gate, the discharge flow can be precisely adjusted to meet the needs of different water conservancy projects such as irrigation, flood control, and navigation;

[0003] When the gate is opened, the water flow is prone to forming eddies and turbulence on both sides, resulting in unstable flow patterns, affecting the normal operation of water conservancy projects, and also having an adverse impact on the ecological environment of the surrounding waters.

[0021] Please see Figure 1-5 This utility model provides a water gate device for water conservancy projects, including a device body 1. A gate plate 2 is movably installed inside the device body 1. A drive rod 3 is installed on the upper side of the gate plate 2. A flow guiding component 4 is installed on the gate frame of the device body 1.

A positioning plate 41 is fixedly installed at the end of the flow guiding plate A44. A fixing column 42 is fixedly installed on the top of the positioning plate 41. A fixing piece 43 is fixedly installed at the end of the fixing column 42 away from the positioning plate 41. The fixing piece 43 is screwed and fixed to the gate frame of the device body 1.

[0022] Working principle: First, the flow guiding assembly 4 is fixedly connected to the device body 1.

The arc-shaped guide plates A44 and B441 effectively guide the water flow when the gate 2 is opened, allowing the water to pass through the gate 2 more smoothly, avoiding eddies and turbulence, and forming a stable and uniform flow pattern, which is conducive to the safe and stable operation of the water conservancy project. They also effectively disperse the impact force of the water flow on the gate and reduce the vibration of the gate 2 caused by the water flow impact. The flow is smooth, reducing the risk of wear and fatigue damage to the gate 2 components, and improving the reliability and safety of gate operation; the water flows in a predetermined direction, avoiding direct impact on the gate 2 and gate chamber structure, reducing the scouring and erosion of the gate 2 and surrounding structures, and extending their service life; the concentrated water flow energy is dispersed, reducing the local flow velocity and impact force, allowing the water to pass through the gate 2 more smoothly, reducing the generation of water turbulence and vortices, which is conducive to improving the overall stability and safety of the water conservancy project; the guide plates A44 and B441 can guide the water flow evenly through the gate 2, avoiding the blockage and obstruction of the water flow in local areas, thereby increasing the flow capacity of the gate 2 to a certain extent, which is conducive to dealing with special situations such as floods and improving the flood control and disaster reduction capabilities of the water conservancy project; the arc-shaped guide plates A44 and B441 make the water flow smoother, reducing drastic changes in water flow and noise, which helps to reduce disturbance and damage to aquatic organisms, protect the living environment of aquatic organisms, and maintain the balance of the river ecosystem.

[0023] In a preferred embodiment, the flow guiding assembly 4 includes a positioning seat 40, a positioning plate 41, a fixing stud 411, a fixing nut 412, a fixing post 42, a fixing piece 43, a flow guiding plate A44, a flow guiding plate B441, an arc-shaped surface 45, an opening 46, a mounting seat 47, and a tie rod 48. The top of both the flow guiding plate A44 and the flow guiding plate B441 is equipped with a fixing post 42, which is arranged in an "L" shape.

[0024] As a preferred embodiment, both the guide plate A44 and the guide plate B441 have multiple sets of openings 46 inside. Both the guide plate A44 and the guide plate B441 are arc-shaped structures made of engineering plastic material, and the cross-sections of the guide plate A44 and the guide plate B441 are "C" shaped.

[0025] In a preferred embodiment, the positioning plate 41 is adapted to the size of the positioning seat 40. The positioning seat 40 is configured as two sets that are respectively fixedly installed on the gate frame of the device body 1. The positioning plate 41 is inserted into the interior of the positioning seat 40. The bottom of the positioning seat 40 is provided with a through hole. The bottom of the positioning plate 41 is fixedly installed with a fixing stud 411.

[0026] In a preferred embodiment, the bottom of the fixing stud 411 passes through the through hole at the bottom of the positioning seat 40 and is screwed and fixed with the fixing nut 412. The positioning plate 41 is inserted inside the positioning seat 40 and is locked by the positioning plate 41, the fixing stud 411, the fixing post 42, and the fixing piece 43.

[0027] As a preferred embodiment, both the inner walls of the guide plate A44 and the guide plate B441 are provided with arc-shaped surfaces 45, and both the inner walls of the guide plate A44 and the guide plate B441 are fixedly provided with mounting bases 47.

[0028] In a preferred embodiment, the guide plate A44 and the guide plate B441 are arranged in a figure-eight shape. The guide plate A44 and the guide plate B441 are detachable structures on the device body 1. The guide plate A44 and the guide plate B441 are symmetrical about the central axis of the gate plate 2.

[0029] The arc-shaped guide plate A44 and guide plate B441 are fixed together by five sets of equidistant tie rods 48. The tie rods 48 keep the guide plates A44 and B441 in a relatively fixed position, preventing relative displacement or deformation under the action of external forces such as water flow impact, ensuring the stability of the overall structure of the guide plate and enabling it to better perform its guiding function. The five sets of equidistant tie rods 48 can evenly distribute the force of the water flow on the guide plate, avoiding stress concentration. When the water flow impacts the guide plate, the tie rods 48 can transfer the force to the entire structure, so that all parts of the guide plate are evenly stressed, reducing the risk of local damage and extending the service life of the guide plate. The tie rods 48 make the two guide plates form an integral load-bearing structure, and when subjected to water flow impact, they can work together to resist external forces. Compared with the case without tie rods 48, the overall structure has stronger impact resistance, can withstand greater water flow impact force, and reduces the possibility of structural damage caused by water flow impact.
