Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology and relates to a composite device for water conservancy engineering that prevents blockage and reinforces flow. Background Technology

[0002] In hydraulic engineering, flow diversion devices are core equipment for controlling water flow direction, balancing pipeline pressure, and preventing blockages. Traditional flow diversion devices face the following technical bottlenecks in practical applications:

[0003] The existing flow guiding devices lack flexibility, as most adopt rigid fixed structures and cannot dynamically adjust the flow guiding angle according to changes in water flow rate or direction. For example, some devices fix the flow guiding pipe with bolts, requiring manual shutdown for adjustment, which leads to response lag and can easily cause local water flow congestion or reduced flow guiding efficiency.

[0004] The diversion port has weak anti-clogging capabilities, and the ends of the diversion pipe are often blocked by the accumulation of mud, sand and gravel. Traditional solutions mostly rely on fixed filter screens to intercept impurities, but the filter screens are easily damaged or blocked by long-term rinsing and are difficult to replace. Water flow needs to be interrupted for maintenance, which affects the continuity of the project. Utility Model Content

Detailed Implementation

[0030] The following detailed description is provided in conjunction with specific implementation methods.

[0031] like Figure 1 As shown, the anti-blockage diversion and reinforcement water conservancy engineering composite device includes an adjustment structure 1. The adjustment structure 1 includes a U-shaped plate 7. A threaded rod 9 is rotatably connected between the two side plates of the U-shaped plate 7. One end of the threaded rod 9 is fixedly connected to the rotating end of a servo motor 8. The servo motor 8 is fixedly connected to the outer wall of the side plate of the U-shaped plate 7. The threaded rod 9 is threadedly connected to the fixing structure 2.

[0032] The fixing structure 2 includes a first connecting block 10. A threaded rod 9 passes through the first connecting block 10 and is threadedly connected to it. A fixing plate 11 is fixedly connected to one side of the first connecting block 10 facing the opening direction of the U-shaped plate 7. An arc-shaped groove 12 perpendicular to the axial direction of the threaded rod 9 is opened on the other side of the fixing plate 11, and a guide tube 3 is placed in the arc-shaped groove 12. Several diversion tubes 4 are connected to the side wall of the guide tube 3. The diversion tubes 4 are perpendicular to the bottom surface of the U-shaped plate 7. The other end of the diversion tube 4 is connected to an anti-blocking structure 5, and the side wall of the diversion tube 4 is connected to a pressure relief structure 6.

[0033] The servo motor 8 is equipped with a waterproof sleeve and a reducer. The reducer has an IP68 waterproof sleeve to prevent water from entering the motor and causing a short circuit. It can also drive the angle adjustment of the guide tube with a response time of less than 3 seconds to adapt to different water flow directions.

[0034] Servo motor 8 drives threaded rod 9 to rotate, which in turn moves fixed structure 2 along the axial direction of threaded rod 9, achieving precise adjustment of the guide pipe angle by ±15° to adapt to different water flow directions.

[0035] The connecting surface between the fixing plate 11 and the first connecting block 10 is also fixedly connected to the second connecting block 26. The second connecting block 26 is symmetrically arranged along the first connecting block 10. Two sliding rods 25 parallel to the threaded rod 9 are fixedly connected inside the U-shaped plate 7. The sliding rods 25 are symmetrical along the threaded rod 9 and are slidably connected to the second connecting block 26. The sliding rods 25 cooperate with the second connecting block 26 to ensure that the fixing plate 11 moves in a straight line with an adjustment accuracy of ±1mm.

[0036] The inner wall of the guide pipe is designed with a corrugated structure, which extends along the axial direction of the guide pipe to guide water flow and reduce impurity adhesion. The corrugated structure has a wavelength of 50mm and an amplitude of 10mm, which disrupts laminar flow, reduces impurity deposition, reduces drag and prevents clogging, and improves the flow guiding efficiency by 20%.

[0037] The adjustment structure 1 also includes an auxiliary spring, which is located between the base plate of the U-shaped plate 7 and the fixed structure 2. One end of the auxiliary spring is connected to the base plate of the U-shaped plate 7, and the other end is fixedly connected to the fixed structure 2 opposite to the base plate. The auxiliary spring has a stiffness coefficient of 50 N / mm, absorbing the impact of motor start-up and shutdown, buffering the impact force during adjustment, and extending the lifespan of the device.

[0038] like Figure 2 As shown, an arc-shaped clamping plate 14 is also provided between the arc-shaped groove 12 and the guide pipe 3. Threaded posts 13 are symmetrically provided on the two ungrooved side walls of the fixed plate 11. The threaded posts 13 penetrate the fixed plate 11 and sequentially rotate to connect the fixed plate 11 and the arc-shaped clamping plate 14. By rotating the threaded posts 13, the arc-shaped clamping plate 14 is tightened, thereby clamping the guide pipe 3. The clamping force is adjustable in the range of 50-200N to prevent pipe displacement.

[0039] When the threaded post 13 is not fully locked, the guide tube 3 can slide along the arc groove 12 to achieve a small angle rotation around the center. The arc groove allows for ±15° angle compensation to adapt to the thermal expansion and contraction of the pipeline.

[0040] like Figure 3 As shown, the anti-clogging structure 5 includes a first extension tube 15, and an installation structure 17 is symmetrically arranged on the side wall of the first extension tube 15. One end of the first extension tube 15 is detachably connected to the end of the diversion tube 4, and the other end is detachably equipped with a filter screen 16. The first extension tube 15 and the filter screen 16 are threadedly connected. The mesh diameter of the filter screen 16 is 0.5-2mm, which is used to intercept impurities such as mud and sand and debris. The detachable design makes it easy to clean, and the cleaning and replacement time is less than 5 minutes.

[0041] The thread tightening torque is 20 N·m to ensure the filter screen seal; the adjustable mesh size adapts to different water qualities, such as riverbeds with a sediment content of 30-100 kg / m³. 3 .

[0042] like Figure 4 As shown, the installation structure 17 includes a cylindrical body 18. The outer bottom wall of the cylindrical body 18 is fixedly connected to the outer wall of the first extension tube 15. A buffer spring 19 is provided inside the cylindrical body 18. One end of the buffer spring 19 is fixedly connected to the inner bottom wall of the cylindrical body 18, and the other end of the buffer spring 19 is fixedly connected to one side of the connecting plate 20. The other side of the connecting plate 20 is fixedly connected to the locking block 21. The top of the locking block 21 is hemispherical. The side wall of the diversion tube 4 is provided with a locking groove that cooperates with the locking block 21. The connecting plate 20 drives the locking block 21 to slide in the locking groove of the diversion tube 4, which can also ensure that the filter screen axis is aligned with the diversion tube.

[0043] The mounting structure 17 absorbs the impact force of water flow through the buffer spring 19, reducing filter screen vibration and playing a buffering and shock-absorbing role. In addition, the buffer spring 19 can provide 5-10mm displacement compensation to adapt to pipe deformation.

[0044] like Figure 5 As shown, the pressure relief structure includes a second extension tube 22. Traction springs 23 are provided at both ends inside the second extension tube 22. The bottom end of the traction spring 23 is fixedly connected to the second extension tube 22, and the top end of the traction spring 23 is fixedly provided with a pressure relief tube 24 with a leakage hole.

[0045] When the pipeline pressure exceeds the threshold by more than 0.5MPa, the traction spring 23 is compressed, and the pressure relief pipe 24 moves down to release the high-pressure water flow. The leak hole diameter is 10mm. The leak hole design balances the pressure inside and outside the pipeline and prevents cavitation damage to the pipe wall.

[0046] Guide blocks are also provided at both ends of the second extension tube 22. The guide blocks are fixedly connected to the inner wall of the second extension tube 22. The traction spring 23 is sleeved on the outside of the guide block to guide the movement direction of the pressure relief tube 24. The guide block restricts the pressure relief tube to move only along the axial direction to prevent offset and jamming, and the response time is less than 0.5 seconds.

[0047] A sliding bearing is provided at the connection between the second connecting block 26 and the slide rod 25. The inner ring of the sliding bearing is fixedly connected to the slide rod 25, and the outer ring is fixedly connected to the second connecting block 26. The coefficient of friction of the sliding bearing is less than 0.05, resulting in low-friction motion, thereby reducing adjustment energy consumption and extending service life.

[0048] All electrical components in this application are connected to an external main controller and 220V AC mains power.
