Description

Technical Field

[0001] This utility model relates to the field of flood discharge equipment technology, specifically a flood discharge equipment for water conservancy projects. Background Technology

[0002] Flood discharge refers to the process in water conservancy projects of quickly releasing excess water by opening flood discharge facilities (such as sluice gates and spillways) to regulate reservoir water levels, prevent flooding, or reduce flood pressure on downstream river channels. This process effectively ensures the safe operation of water conservancy projects and reduces the risk of natural disasters.

[0003] Currently, existing flood discharge equipment for water conservancy projects typically controls the pressure of river flow. However, when these equipment discharges water directly, the impact of the water flow is significant, affecting the downstream river channel. This results in a lack of buffering for the water flow. Furthermore, the valves in existing flood discharge equipment are single and obstruct the discharge outlet. When valves malfunction or seals fail, maintenance and replacement are inconvenient, leading to problems with valve maintenance. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Please see Figures 1 to 5 The present invention provides a technical solution including a flood discharge body 1, a flood discharge port 7 inside the flood discharge body 1, a valve structure inside the flood discharge port 7, a first outward expansion groove 12 in the middle of the flood discharge port 7, a second outward expansion groove 13 outside the flood discharge port 7, a buffer block 10 fixedly connected to one side of the flood discharge body 1, a guide groove 8 and an energy dissipation angle 9 on the upper part of the buffer block 10, a discharge groove 11 at the lower part of the flood discharge body 1 and the buffer block 10, a connecting frame 2 on one side of the flood discharge body 1, a maintenance baffle 16 slidably connected inside the connecting frame 2, a second moving screw 15 threadedly connected to the upper part of the maintenance baffle 16, an output shaft of a servo motor 14 fixedly connected to the upper part of the second moving screw 15, and a connecting frame 2 fixedly connected to one side of the servo motor 14.

[0026] Please see Figures 1 to 2 The main baffle 17 of the valve structure slides inside the flood discharge body 1, and the main baffle 17 blocks the flood discharge port 7. The upper part of the main baffle 17 is fixedly connected to the first moving screw 5.

[0027] Specifically, the main baffle 17 and the maintenance baffle 16 are made of corrosion-resistant and high-strength materials. The main baffle 17 blocks the external flow of the flood discharge outlet 7, and the maintenance baffle 16 blocks the internal flow of the flood discharge outlet 7.

[0028] Please see Figures 1 to 2 The outer side of the first moving screw 5 moves axially inside the flood discharge body 1. The upper part of the flood discharge body 1 is rotatably connected to the turntable 6, and the turntable 6 is threadedly connected to the first moving screw 5.

[0029] Specifically, a sealing structure is provided on the upper part of the main baffle 17.

[0030] Please see Figures 1 to 3 The flow guide 8 is inclined downwards, and the energy dissipation angle 9 is annular. The flow guide 8 and the energy dissipation angle 9 are connected. The flow guide 8 and the energy dissipation angle 9 are set in a step-like manner downwards.

[0031] Specifically, the flow guide trough 8 and the energy dissipation angle 9 form a flow-lifting nose sill, which is set in a stepped manner with 3-5 steps.

[0032] Please see Figure 1 , Figures 4 to 6 The servo motor 14 is connected to an external control structure via wires. The upper bearing of the second moving screw 15 is connected to a connecting frame 2. A connecting block 3 is fixedly connected to the upper part of the connecting frame 2. The lower part of the connecting block 3 is in contact with the flood discharge body 1.

[0033] Specifically, the connecting block 3 and the upper part of the connecting frame 2 form an L-shape.

[0034] Please see Figure 1 , Figure 6 A fixing bolt 4 is inserted inside the connecting block 3. A reinforcing plate is provided at the lower part of the fixing bolt 4. The flood discharge body 1 is fixedly connected to the lower part of the fixing bolt 4. The reinforcing plate is located inside the flood discharge body 1.

[0035] Specifically, the fixing bolt 4 is an embedded part, and the lower reinforcing plate of the fixing bolt 4 is embedded into the flood discharge body 1.

[0036] During use, water can flow out through the lower spillway 11, allowing water to flow within the river channel. The spillway 11 and buffer block 10 effectively drain the river. During flood discharge, water enters the flood outlet 7, where the flow velocity is relatively high. As it moves into the first expansion channel 12, the internal space increases, increasing the volume of water discharged and reducing the flow velocity. It then enters the second expansion channel 13, further reducing the flow velocity. The water discharged from the flood outlet 7 flows downward through the guide channel 8 and is buffered by the energy dissipation angle 9. The stepped design reduces the impact on the water flow, and the existing river water further buffers the impact. Through the coordinated design of the guide channel 8, energy dissipation angle 9, first expansion channel 12, and second expansion channel 13, the impact of the flood discharge flow is reduced during use, thereby reducing the impact on the lower river channel and achieving the purpose of buffering the water flow.

[0037] During flood discharge, rotating the turntable 6 causes the first moving screw 5 to move upward, which in turn moves the main baffle 17 upward, retracting it into the flood discharge body 1. This opens the flood discharge port 7 for flood discharge. The connection frame 2 of the maintenance valve is fitted into the flood discharge body 1, and the connection block 3 is hung on the flood discharge body 1. The fixing bolt 4 is pre-embedded in the flood discharge body 1, and a reinforcing plate is installed at the lower part of the fixing bolt 4 to increase its stability. This ensures a fixed connection between the connection frame 2 and the flood discharge body 1. Through the arrangement of the connection frame 2, connection block 3, and fixing bolt 4, the maintenance valve and the flood discharge body 1 are securely connected. The effect of connecting the main body 1 is that, when the main valve is being repaired, the servo motor 14 is started through the external control structure, which drives the second moving screw 15 to move the maintenance baffle 16 in the connecting frame 2 downward, blocking the front end of the flood discharge port 7, thereby preventing water flow in the flood discharge port 7, which facilitates the repair of the main valve. Through the coordinated setting of the servo motor 14, the second moving screw 15 and the maintenance baffle 16, the water flow can be blocked during the repair of the main valve, thus facilitating the repair of the main valve and achieving the purpose of easy valve repair.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
