Description

Technical Field

[0001] This invention relates to the field of rotary weir equipment technology, and in particular to a process-sealed rotary weir. Background Technology

[0002] As a core piece of equipment in the fields of water conservancy regulation, municipal sewage treatment and industrial fluid control, the core requirement of process sealing rotary weir is to achieve precise opening and closing through the rotation of the weir body, while maintaining reliable sealing throughout the entire operating cycle to avoid operational disruptions or environmental impacts caused by media leakage.

[0003] Chinese Patent Publication No. CN223269176U discloses a process-sealed rotary weir, including a weir gate. One side of the weir gate is connected to a wall via a hydraulic cylinder. A P-type sealing strip is provided at the outer edge of the weir gate, and a second sealing strip is provided on the wall. A pressure plate is provided on the weir gate to limit and fix the P-type sealing strip. This utility model relates to the field of rotary weir technology. This device, through the setting of the P-type sealing strip, ensures that it remains in close contact with the wall during rotation, thereby guaranteeing that the weir gate has a stop at every angle during rotation. The effect of water flow; through the coordinated setting of the P-type sealing strip II, the bottom of the weir gate always maintains a strong seal when rotating, ensuring the sealing effect; at the same time, the cooperation of the pressure plate and connecting parts not only facilitates the adjustment of the position of the P-type sealing strip I, but also facilitates its disassembly and replacement. However, in actual use, when the weir rotates, the friction and uneven force between the sealing rubber and the inner wall of the channel can easily cause severe deformation of the rubber. This will not only significantly reduce the effective contact area between the rubber and the channel, leading to a decrease in sealing performance, but also accelerate rubber wear and shorten its service life. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, the side sealing device and the bottom sealing device work together to simultaneously seal the gaps between the weir gate and the inner wall of the channel, and between the rotating shaft and the inner wall of the channel, ensuring that the weir gate remains tightly sealed throughout the entire rotation angle range and preventing media leakage.

[0018] 2. In this invention, the rubber is supported by the first and second supporting arc plates, which helps it to restore its shape after compression, thereby reducing the demand on the elasticity of the rubber material itself. The reduction of the elasticity of the rubber material itself can improve the wear resistance of the rubber. Improving the wear resistance of the U-shaped rubber can improve the overall lifespan and extend the maintenance interval.

[0019] 3. In this invention, under the combined action of the rotating shaft and the positioning mechanism, the hydraulic push rod one and the hydraulic push rod two dynamically switch actions as the weir rotates. During the rotation, the rubber friction is reduced, and after the opening and closing are in place, the rubber is pressed to improve the fit, thus achieving the dual effects of rotational resistance reduction and static sealing enhancement.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] Example 1

[0041] like Figure 1 - Figure 3 As shown, this embodiment discloses a process sealing rotary weir, including a channel 1. A rotating shaft 2 is provided on both sides of the inner cavity of the channel 1. A weir gate 3 is provided on the outer surface of the rotating shaft 2. Two hydraulic cylinders 4 are rotatably mounted on the inner cavity surface of the channel 1 on one side of the outer surface of the two weir gates 3. Side sealing devices 5 are provided on both sides of the outer surface of the two weir gates 3. A bottom sealing device 6 is fixedly mounted on the inner cavity surface of the channel 1 on one side of the outer surface of the two rotating shafts 2.

[0042] Specifically, during the opening and closing of the weir gate 3, the hydraulic cylinder 4 drives the weir gate 3 to rotate around the rotating shaft 2 to realize the opening and closing action of the weir gate 3. During this process, the rotating shaft 2 synchronously links the side sealing devices 5 on both sides. The side sealing devices 5 are used to seal the gap between the weir gate 3 and the inner wall of the channel 1. At the same time, the bottom sealing device 6 is used to seal the gap between the rotating shaft 2 and the inner wall of the channel 1. Through the synergistic effect of the side sealing devices 5 and the bottom sealing devices 6, the gaps on both sides and the bottom of the rotating weir can be sealed to ensure that the weir gate 3 remains sealed throughout the entire rotation angle range.

[0043] To facilitate the replacement of U-shaped rubber 55 by staff, such as Figure 4 As shown, the side sealing device 5 includes a first fixing plate 51 and a second fixing plate 52. Both the first fixing plate 51 and the second fixing plate 52 are fixedly installed on the outer surface of the weir gate 3. A pressing strip is provided on the side of the outer surface of the first fixing plate 51 and the second fixing plate 52 away from the weir gate 3. A fixing mechanism 53 is fixedly installed on the outer surface of the weir gate 3 between the first fixing plate 51 and the second fixing plate 52. A positioning mechanism 54 is provided on the side of the outer surface of the fixing mechanism 53 away from the weir gate 3. A U-shaped rubber 55 is clamped between the fixing mechanism 53 and the first fixing plate 51 and the second fixing plate 52.

[0044] Specifically, during the installation and replacement of the U-shaped rubber 55, the operator can operate the fixing mechanism 53 to disassemble and install the U-shaped rubber 55. During the rotation of the weir gate 3 driven by the hydraulic cylinder 4, the rotating shaft 2 can be linked to the positioning mechanism 54. This ensures that the U-shaped rubber 55 fits tightly against the inner wall of the channel 1 when the weir gate 3 is in the closed or open state. At the same time, the positioning mechanism 54 supports the rubber, helping the U-shaped rubber 55 to restore its shape after compression. This reduces the demand on the elasticity of the rubber material itself. The reduction in the elasticity of the rubber material itself can improve the wear resistance of the rubber. Improving the wear resistance of the U-shaped rubber 55 can increase the overall service life and extend the maintenance interval.

[0045] Furthermore, the fixing plate 51 is fixedly installed on the outer surface of the weir gate 3 by multiple bolts. When it is necessary to adjust the fixing plate 51, the staff can adjust the position of the fixing plate 51 by rotating the multiple bolts.

[0046] Furthermore, multiple placement holes are provided in the middle of the clamping strips on the outer surfaces of fixing plate 51 and fixing plate 52. Multiple bolts that are compatible with the placement holes are installed on the clamping strips. The bolts can pass through the placement holes to clamp the U-shaped rubber 55.

[0047] For the workers to replace and install the U-shaped rubber 55, such as Figure 5 and Figure 6 As shown, the fixing mechanism 53 includes a mounting frame 531, which is fixedly mounted on the outer surface of the weir gate 3. A limiting frame 532 is provided in the middle of the inner cavity of the mounting frame 531. Multiple pushing members 533 are slidably mounted on both sides of the outer surface of the limiting frame 532. Multiple connecting blocks 534 are provided in the middle of the inner cavity of the limiting frame 532. Both ends of the multiple connecting blocks 534 extend to the outside of the limiting frame 532, and both ends of the multiple connecting blocks 534 are fixedly connected to the outer surfaces of the multiple pushing members 533 on both sides. A transmission rod 535 is provided in the middle of the multiple connecting blocks 534. The end of the transmission rod 535 away from the rotating shaft 2 extends to the outside of the mounting frame 531. The inner wall of the multiple connecting blocks 534 is threadedly connected to the outer surface of the transmission rod 535. On the side of the outer surface of the two pushing members 533 that is away from each other, a fixing plate 536 is provided that is slidably mounted in the inner cavity of the mounting frame 531. The two fixing plates 536 are adapted to and used with fixing plate 51 and fixing plate 52 respectively.

[0048] Specifically, the pusher 533 consists of two trapezoidal blocks, which are slidably connected by inclined surfaces. When the operator rotates the transmission rod 535, the transmission rod 535 is threadedly connected to multiple connecting blocks 534, so the multiple connecting blocks 534 will be displaced along the transmission rod 535. Therefore, the trapezoidal blocks fixed to the connecting blocks 534 will also be displaced. When the trapezoidal blocks fixed to the connecting blocks 534 move, the other trapezoidal block will drive the fixed plate three 536 fixed to it to move closer to or further away from the transmission rod 535, thereby adjusting the distance between the two fixed plates three 536 and the fixed plate one 51 and the fixed plate two 52, respectively.

[0049] Furthermore, when replacing the U-shaped rubber 55, the operator can first rotate the transmission rod 535 in the reverse direction, so that the transmission rod 535 drives the multiple pushers 533 on both sides through multiple connecting blocks 534, thereby driving the two fixing plates 536 to move closer to the transmission rod 535. Then, remove the U-shaped rubber 55 to be replaced, install the new U-shaped rubber 55, and rotate the transmission rod 535 in the forward direction, so that the two fixing plates 536 clamp and fix the U-shaped rubber 55, thus completing the replacement of the U-shaped rubber 55.

[0050] Furthermore, the end of the transmission rod 535 extending outside the mounting frame 531 is provided with a groove for a screwdriver, which allows the operator to drive the transmission rod 535 to rotate.

[0051] In order to support the U-shaped rubber 55 when the weir gate 3 rotates, such as Figure 7 and Figure 8 As shown, the positioning mechanism 54 includes a mounting handle 541, which is fixedly mounted on the outer surface of the mounting frame 531. Supporting arc plates 542 are provided on both sides of the outer surface of the mounting handle 541, and supporting arc plates 543 are provided on the side of the outer surface of the mounting handle 541 away from the fixing mechanism 53. Multiple transmission components 544 are provided in the middle of the mounting handle 541. The multiple transmission components 544 are fixedly connected to the two supporting arc plates 542 and the supporting arc plates 543. Connecting rods 545 are provided between the multiple transmission components 544, and connecting rods 545 are provided on both sides of the transmission component 544 near the rotating shaft 2. Multiple springs 546 fixedly mounted on the outer surface of the mounting handle 541 are provided at intervals on the multiple connecting rods 545.

[0052] Specifically, when the weir gate 3 is in the closed or open state, the second support arc plate 543 will press against the U-shaped rubber 55 under the drive of the transmission component 544, so that the U-shaped rubber 55 fits tightly against the inner wall of the channel 1 to achieve a sealing effect. When the weir gate 3 rotates, the rotating shaft 2 drives the transmission component 544 to move, so that the transmission component 544 pulls the second support arc plate 543 to move closer to the fixed mechanism 53, and at the same time pushes the first support arc plates 542 on both sides to move outward. The two support arc plates 542 press against the two sides of the U-shaped rubber 55. This can prevent the friction between the channel 1 and the U-shaped rubber 55 during the rotation of the weir gate 3 from causing serious deformation of the U-shaped rubber 55, preventing a significant reduction in its effective contact area with the channel 1 and damage to the sealing effect. At the same time, it can reduce the wear rate of the U-shaped rubber 55 and extend its service life.

[0053] Furthermore, when the weir gate 3 rotates, the rotating shaft 2 drives multiple transmission components 544 to move through multiple connecting rods 545: when the two supporting arc plates 542 move outward, the spring 546 is in a slightly tensile state; when the supporting arc plate 543 extends and contacts the U-shaped rubber 55, the spring 546 is in a compressive state.

[0054] To help the U-shaped rubber 55 return to its initial shape after being compressed by the rotation of the weir 3 when the weir 3 stops moving, such as... Figure 9 As shown, the transmission component 544 includes a mounting cylinder 5441. A piston 5442 is provided in the middle of the inner cavity of the mounting cylinder 5441. The end face of the piston 5442 is fixedly connected to the end face of the connecting rod 545. Hydraulic push rods 1 and 5443 are provided on both sides of the outer surface of the piston 5442. A hydraulic push rod 2 and 5444 are provided on the side of the outer surface of the mounting cylinder 5441 away from the weir gate 3. Both hydraulic push rods 1 and 5443 and hydraulic push rod 2 and 5444 extend to the outside of the mounting handle 541. The extended ends of the two hydraulic push rods 1 and 5443 are fixedly connected to the inner surfaces of the two supporting arc plates 1 and 542, respectively. The extended end of the hydraulic push rod 2 and 5444 is fixedly connected to the inner surface of the supporting arc plate 2 and 543.

[0055] Specifically, when the hydraulic cylinder 4 drives the weir gate 3 to rotate, the rotating shaft 2 drives the piston 5442 to move through multiple connecting rods 545, which presses the hydraulic oil on one side of the inner cavity of the mounting cylinder 5441 into the inner cavity of the two hydraulic push rods 5443. This causes the two hydraulic push rods 5443 to drive the support arc plate 542 to move. The support arc plate 542 then presses against both sides of the U-shaped rubber 55. During this process, the hydraulic oil in the inner cavity of the second hydraulic push rod 5444 is drawn into the inner cavity of the other side of the mounting cylinder 5441, causing the second hydraulic push rod 5444 to drive the support arc plate 543 to move closer to the fixed mechanism 53. This reduces the frictional resistance between the U-shaped rubber 55 and the inner wall of the channel 1 when the weir gate 3 rotates.

[0056] Furthermore, as the weir gate 3 gradually moves to the closed or fully open state, the rotating shaft 2 will drive the piston 5442 to move towards the side closer to the hydraulic push rod 5444 through multiple connecting rods 545, so that the hydraulic push rod 5444 drives the support arc plate 543 to gradually fit against the inner surface of the U-shaped rubber 55, thereby improving the sealing performance between the U-shaped rubber 55 and the inner wall of the channel 1.

[0057] Example 2

[0058] This embodiment further improves upon Embodiment 1 by modifying the rotating shaft 2. To utilize the force of the hydraulic cylinder 4 driving the weir gate 3 to rotate, the rotating shaft 2 can then drive the side sealing device 5. For example... Figure 10 and Figure 11 As shown, the rotating shaft 2 includes a mounting shaft 21, which is fixedly mounted on the inner surface of the channel 1. A connecting cylinder 22 is rotatably mounted on the outer surface of the mounting shaft 21. A connecting arc plate 23 and two braking components 24 are provided on the side of the inner cavity of the connecting cylinder 22 near the side sealing device 5. The two braking components 24 are fixedly mounted on the outer surface of the mounting shaft 21. A limit mechanism 25 is provided on the side of the outer surface of the mounting shaft 21 near the side sealing device 5. The inner cavities of the two braking components 24 and the inner cavity of the limit mechanism 25 are connected through a hydraulic pipe.

[0059] Specifically, when the hydraulic cylinder 4 drives the weir gate 3 to rotate, the weir gate 3 will drive the connecting cylinder 22 to rotate around the mounting shaft 21. During this process, the connecting cylinder 22 drives the two limiting mechanisms 25 to move through the connecting arc plate 23, thereby causing the limiting mechanisms 25 to pull the connecting rod 545 to move.

[0060] In order to achieve the purpose of the limiting mechanism 25 driving the connecting rod 545 to move under the action of the braking component 24, such as Figure 12 As shown, the limiting mechanism 25 includes a mounting ring 251, which is fixedly mounted on the inner wall of the mounting shaft 21. Limiting elements 254 are provided on both sides of the inner cavity of the mounting ring 251. A connecting handle 252 is provided in the middle of the inner cavity of the mounting ring 251. The outer surface of the connecting handle 252 is fixedly connected to the end face of the connecting rod 545 on the side of the positioning mechanism 54 near the mounting shaft 21. A hydraulic pulling rod 253 is provided in the inner cavity of the mounting ring 251. Two limiting blocks 2531 are provided on the outer surface of the hydraulic pulling rod 253 near the connecting handle 252. The two limiting blocks 2531 are adapted to the two limiting elements 254. A connecting ring 255 is provided on the end face of the hydraulic pulling rod 253. The connecting ring 255 is rotatably mounted on the bottom wall of the inner cavity of the mounting ring 251.

[0061] To limit the hydraulic pull rod 253, such as Figure 13As shown, the limiting member 254 includes an arc-shaped slide 2541, which is fixedly installed on the inner surface of the mounting ring 251. An inclined slide 2542 is provided on both sides of the arc-shaped slide 2541 and fixedly installed on the inner surface of the mounting ring 251. A limiting slide 2543 is provided on the side of the two inclined slides 2542 that are far apart from each other and fixedly installed on the inner surface of the mounting ring 251. The inner cavities of the arc-shaped slide 2541, the inclined slide 2542 and the limiting slide 2543 are connected.

[0062] Specifically, when the weir gate 3 rotates, the connecting cylinder 22 drives the two brake components 24 to move sequentially through the connecting arc plate 23. During this process, the limiting block 2531 on the outer surface of the hydraulic pull rod 253 first slides a distance in the inner cavity of the limiting slide 2543 on one side. When the limiting block 2531 enters the inner cavity of the inclined slide 2542, the spring 2 546, which is under compression, will push multiple connecting rods 545 to move, thereby causing the connecting rods 545 to drive the hydraulic pull rod 253 to extend through the connecting handle 252. At this time, the hydraulic oil in the inner cavity of the brake component 24, which is closest to the connecting arc plate 23, will be injected into the inner cavity of the hydraulic pull rod 253.

[0063] Furthermore, when the connecting rod 545 drives the hydraulic pull rod 253 to move a certain distance through the connecting handle 252, the limiting block 2531 slides into the inner cavity of the arc-shaped slide 2541. When the weir gate 3 gradually moves to the fully closed or fully open state, the limiting block 2531 will gradually slide into the inner cavity of the other inclined slide 2542. At this time, the connecting arc plate 23 will also contact the other braking component 24, causing the braking component 24 to draw hydraulic oil from the inner cavity of the hydraulic pull rod 253. This causes the hydraulic pull rod 253 to pull the connecting rod 545 through the connecting handle 252, thereby driving multiple connecting rods 545 to pull multiple transmission components 544. Subsequently, the limiting block 2531 enters the inner cavity of the other limiting slide 2543, at which point the weir gate 3 is in the fully closed or fully open state.

[0064] In order to drive the movement of the limit mechanism 25, such as Figure 14 — Figure 16As shown, the braking component 24 includes an arc-shaped frame 241, which is fixedly mounted on the outer surface of the mounting shaft 21. An arc-shaped frame 242 is provided in the middle of the arc-shaped frame 241, and an arc-shaped block 243 is provided in the middle of the arc-shaped frame 242. An arc-shaped push handle 244 is provided on the outer surface of the arc-shaped block 243. A spring is provided between the end face of the arc-shaped frame 242 and the inner wall of the arc-shaped frame 241, and between the end face of the arc-shaped block 243 and the inner wall of the arc-shaped frame 242. A positioning block 2421 is slidably mounted on the outer inner wall of the arc-shaped frame 242. A placement groove 2411 is provided on the top wall of the inner cavity of the arc-shaped frame 241. A strip spring is provided in the inner cavity of the placement groove 2411. A limit groove is provided in the middle of the outer surface of the arc-shaped block 243. The positioning block 2421 is adapted to the placement groove 2411 and the limit groove.

[0065] Specifically, when the weir gate 3 rotates, the connecting arc plate 23 will gradually disengage from the surface of the arc-shaped push handle 244 on one side. During this process, the spring 1 between the arc frame 241, the arc frame 242 and the arc block 243 will contract, causing the arc frame 242 and the arc block 243 to return to their initial positions. The arc block 243 will first contract into the inner cavity of the arc frame 242 under the action of the spring 1. During this process, the positioning block 2421 will disengage from the inner cavity of the placement groove 2411 and embed into the limiting groove on the arc block 243, so that the arc frame 242 and the arc block 243 can move synchronously. Then, the spring 1 between the arc frame 241 and the arc frame 242 will pull the arc frame 242 back to its initial position. During this process, the hydraulic oil between the inner end face of the arc frame 241 and the end face of the arc frame 242 will be injected into the inner cavity of the hydraulic pull rod 253.

[0066] Furthermore, as the weir gate 3 gradually approaches the fully closed or fully open position, the limiting block 2531 enters the inner cavity of the inclined slide 2542 on the other side. At this time, the connecting arc plate 23 drives the arc frame 242 and the arc block 243 to move synchronously through the arc-shaped push handle 244, and the arc frame 242 and the arc block 243 are constrained into one by the positioning block 2421.

[0067] Furthermore, when the connecting arc plate 23 drives the arc frame 242 to move, the hydraulic oil in the inner cavity of the hydraulic pull rod 253 will be injected into the inner cavity of the arc frame 241, causing the hydraulic pull rod 253 to perform a retraction action, which in turn pulls the connecting rod 545 to move through the connecting handle 252.

[0068] Furthermore, when the limiting block 2531 moves to the junction of the limiting slide 2543 and the inclined slide 2542 on the other side, it still needs to continue moving at a certain angle. At this time, the hydraulic oil in the inner cavity of the hydraulic pull rod 253 has been injected into the inner cavity of the arc frame 241, and the arc frame 242 cannot continue to move. The positioning block 2421 is opposite to the placement groove 2411. Therefore, when the arc push handle 244 drives the arc block 243 to move, the limiting groove on the arc block 243 will push the positioning block 2421 into the inner cavity of the placement groove 2411 through the inclined surface, thereby limiting the arc frame 241.

[0069] Furthermore, during the rotation of the weir gate 3, in addition to rotating to the fully open or fully closed state, the weir gate 3 will also stop at any angle to change the water-blocking area. When the weir gate 3 stops rotating at any angle, the U-shaped rubbers 55 on both sides will continue to contact the inner surface of the channel 1 to maintain the sealing effect. At the same time, the U-shaped rubbers 55 on both sides will restore their shape under the support of the two supporting arc plates 542 to prevent the U-shaped rubbers 55 from remaining in a compressed state for a long time, which would affect the sealing effect of the U-shaped rubbers 55 afterwards.

[0070] To facilitate quick replacement of P-shaped rubber 64 by staff, such as Figure 17 and Figure 18 As shown, the bottom sealing device 6 includes a support plate 61, which is fixedly installed on the inner surface of the channel 1. A plurality of bolts 62 are provided in the middle of the outer surface of the support plate 61. An L-shaped plate 65 is provided at the protruding end of the plurality of bolts 62. A P-shaped rubber 64 is provided in the middle of the L-shaped plate 65. The P-shaped rubber 64 is adapted to be used with the connecting cylinder 22. A fixing mechanism 63 for fixing the P-shaped rubber 64 is provided in the middle of the end face of the L-shaped plate 65. The structure of the fixing mechanism 63 is similar to that of the fixing mechanism 53.

[0071] Specifically, the fixing mechanism 2 63 fixes the P-shaped rubber 64 in the same way as the fixing mechanism 1 53. Both use the transmission rod 535 to drive the pusher 533 to squeeze the P-shaped rubber 64, thereby achieving quick installation and removal of the P-shaped rubber 64.

[0072] Furthermore, the operator can adjust the position of the L-shaped plate 65 by turning the bolt 62 to make the P-shaped rubber 64 fit tightly against the outer surface of the connecting cylinder 22. When the surface of the P-shaped rubber 64 wears out after a certain period of service, the operator needs to first release the fixing mechanism 63 from the fixing state of the P-shaped rubber 64, then adjust the L-shaped plate 65 by multiple bolts 62, and then fix the P-shaped rubber 64 by the fixing mechanism 63, so that the P-shaped rubber 64 can continue to fit tightly against the outer surface of the connecting cylinder 22.

[0073] It should be noted that the specific installation method, circuit layout and connection method, and control method of the hydraulic cylinder 4 used in the above embodiment are all conventional designs in the prior art, and will not be described in detail in this invention.
