Description

Technical Field

[0001] This utility model relates to the field of sealing technology for sludge suction machine pools, specifically a sealing device for a mobile sludge suction machine pool. Background Technology

[0002] Odor control is a key focus in the design and operation of wastewater treatment plants. To achieve deodorization, the space above the structures should be sealed. Common sealing methods include using fiberglass canopies or fiberglass curved covers.

[0003] For example, the authorized patent publication number CN211912839U describes a sealing device for the tank of a mobile sludge suction machine. This device uses a zipper head and teeth fixed to a sealing cloth to zip up and seal the area the sludge suction machine passes through, much like a zipper. During the reciprocating motion of the sludge suction machine, the opening position continuously moves, but the size of the opening remains essentially constant, maximizing the sealing effect.

[0004] However, some existing structures are difficult to effectively cover and seal, such as aerated grit chambers and rectangular primary sedimentation tanks. These structures usually have mobile sludge suction machines on top. If a canopy is used for sealing, the sludge suction machine needs to be completely sealed inside the canopy. Existing tanks are covered with canopies, but the cost of canopies is relatively high. Although the above-mentioned patent solves the problem of sealing the tank, the sealing cloth is not convenient to roll up and retract. At the same time, the above-mentioned patent does not mention the effect of the walkway on supporting the movement of the sludge suction machine.

[0005] Therefore, we need a sealing device for the mobile sludge suction machine pool to solve the existing sealing problem of the mobile sludge suction machine pool, and also to realize the rolling and scaling of the sealing cloth of the mobile sludge suction machine pool. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing device for the pool of a mobile sludge suction machine, which solves the problem of sealing the existing mobile sludge suction machine pool mentioned in the background art, and also realizes the rolling and scaling of the sealing cloth of the mobile sludge suction machine pool.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for a mobile sludge suction machine pool, comprising a pool body, a guide plate fixedly connected to the top surface of the pool body, the surface of the guide plate engaging with the surface of an opening, the opening being located within the side plates of a walkway frame, the base of the sludge suction machine body fixedly connected to the top surface of the walkway frame, the end of the input pipe of the sludge suction machine body extending into the interior of the pool body, a sealing cloth fixing plate fixedly connected to the top surface of the side plates of the pool body, the end of a sealing cloth roll fixedly connected to the inner surface of the sealing cloth fixing plate, and the sealing cloth roll being disposed on the surface of the walkway frame.

[0008] Preferably, the two side plates of the walkway frame are provided with an integrally formed stabilizing frame. The surface of the stabilizing frame is rotatably connected to the surface of a rotating rod. The surface of the rotating rod is fixedly connected to the inner ring of the sealing cloth roll. The end of the rotating rod is fixedly connected to a transmission pulley. The surface of the transmission pulley is connected to the surface of a drive pulley via a transmission belt. The inner surface of the drive pulley is fixedly connected to the end of a drive rod. The surface of the drive rod is rotatably connected to the inside of the two side plates of the walkway frame. The surface of the drive rod is fixedly connected to the inside of a gear. The surface of the gear is rotatably connected to the inside of a through-hole. The end of the drive rod is fixedly connected to the end of the output shaft of a servo motor. The base of the servo motor is fixedly connected to the inner surface of the side plate of the walkway frame. The surface of the gear teeth meshes with the surface of the tooth groove, and the tooth groove is opened on the top surface of the guide plate.

[0009] Preferably, the guide plate has an "I" shaped cross-section, and there are two guide plates, which are symmetrically arranged around the center point of the pool.

[0010] Preferably, the opening completely penetrates the surface of the walkway frame, a fixed support rod is fixedly connected to the surface of the opening, the surface of the fixed support rod is rotatably connected to the interior of the guide wheel, the lowest surface of the guide wheel abuts against the top surface of the guide groove, and the guide groove is opened on the top surface of the guide plate.

[0011] Preferably, there are two openings, and the two openings are symmetrically arranged along the center point of the walkway frame. The guide wheels and gears on the surface of the openings have the same radius.

[0012] Preferably, the drive pulley and the transmission pulley have the same radius, and the surfaces of the drive pulley and the transmission pulley are provided with a transmission belt cross-section in the shape of an isosceles trapezoid.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the servo motor is started, the gear rotates on the surface of the opening, so that the walkway frame can move automatically along the guide plate on the top of the pool. The rotation of the drive rod drives the drive pulley to rotate through the transmission belt, which in turn drives the rotating rod to automatically rewind and expand the sealing cloth roll. Therefore, the automatic rewinding of the sealing cloth roll is achieved while the walkway frame moves on the top of the pool, so that the sealing cloth roll covers the top of the pool and thus achieves a sealing effect on the top of the pool. When the walkway frame moves on the top of the pool, the lowest end of the guide wheel abuts against the top of the guide groove to support and guide the movement of the walkway frame. This further solves the problem of pool sealing in existing mobile sludge suction machines and also realizes the rewinding and expansion of the sealing cloth in the pool of mobile sludge suction machines.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1, please refer to Figures 1-6This utility model provides a technical solution: a sealing device for a mobile sludge suction machine pool, including a pool body 1. A guide plate 10 is fixedly connected to the top surface of the pool body 1. The surface of the guide plate 10 engages with the surface of an opening 14. The opening 14 is located inside the side plates of a walkway frame 4. The top surface of the walkway frame 4 is fixedly connected to the base of the sludge suction machine body 5. The end of the input pipe of the sludge suction machine body 5 extends into the interior of the pool body 1. A sealing cloth fixing plate 2 is fixedly connected to the top surface of the side plates of the pool body 1. A sealing cloth fixing plate 2 is fixedly connected to the inner surface of the sealing cloth fixing plate 2. The end of the cloth roll 8 is sealed on the surface of the walkway frame 4. By snapping the surface of the opening 14 onto the surface of the guide plate 10, and fixing the bottom surface of the guide plate 10 to the top surface of the pool body 1, the walkway frame 4 can move along the surface of the guide plate 10 on the top of the pool body 1. By fixing the bottom surface of the sealing cloth fixing plate 2 to the top surface of the pool body 1, and then fixing the end of the sealing cloth roll 8 to the inner surface of the sealing cloth fixing plate 2, the sealing cloth roll 8 seals the inside when the walkway frame 4 moves on the top of the pool body 1.

[0023] Example 2, see attached document Figures 1 to 6 Based on Embodiment 1, in order to achieve a sealing effect on the top of the pool body 1, an integrally formed stabilizing frame 6 is provided on the surface of the two side plates of the walkway frame 4. The surface of the rotating rod 7 is rotatably connected to the inside of the stabilizing frame 6. The inner ring of the sealing cloth roll 8 is fixedly connected to the surface of the rotating rod 7. The end of the rotating rod 7 is fixedly connected to the transmission pulley 19. The surface of the transmission pulley 19 is connected to the surface of the drive pulley 17 through the transmission belt 18. The inner surface of the drive pulley 17 is fixedly connected to the end of the drive rod 16. The surface of the drive rod 16 is rotatably connected to the inside of the two side plates of the walkway frame 4. The surface of the drive rod 16 is fixedly connected to the inside of the gear 15. The surface of the gear 15 is rotatably connected to the inside of the through port 14. The end of the drive rod 16 is fixedly connected to the end of the output shaft of the servo motor 9. The base of the servo motor 9 is fixedly connected to the inner surface of the side plate of the walkway frame 4. The surface of the gear 15 meshes with the surface of the tooth groove 11. The tooth groove 11 is opened on the top surface of the guide plate 10.

[0024] By meshing the teeth of gear 15 with the teeth of gear 11, the internal surface of gear 15 is fixedly connected to the surface of drive rod 16. When servo motor 9 is started, gear 15 rotates on the surface of port 14, so that walkway frame 4 can move automatically along guide plate 10 on top of pool body 1. The rotation of drive rod 16 drives drive pulley 17 to drive drive pulley 19 to rotate through drive belt 18. Thus, drive pulley 19 drives rotating rod 7 so that sealing cloth roll 8 can automatically rewind and expand. Therefore, the walkway frame 4 can automatically rewind sealing cloth roll 8 while moving on top of pool body 1, so that sealing cloth roll 8 can cover the top of pool body 1, thereby achieving a sealing effect on the top of pool body 1.

[0025] Example 3, refer to Appendix Figures 1 to 6Based on Embodiment 2, in order to support and guide the movement of the walkway frame 4, the opening 14 completely penetrates the surface of the walkway frame 4. A fixed support rod 13 is fixedly connected to the surface of the opening 14. The surface of the fixed support rod 13 is rotatably connected to the inside of the guide wheel 12. The lowest surface of the guide wheel 12 abuts against the top surface of the guide groove 3. The guide groove 3 is opened on the top surface of the guide plate 10.

[0026] By fixing a fixed support rod 13 to the surface of the opening 14, and rotating the surface of the fixed support rod 13 to the inside of the guide wheel 12, when the walkway frame 4 moves on the top of the pool body 1, the lowest end of the guide wheel 12 abuts against the top of the guide groove 3 to support and guide the movement of the walkway frame 4.

[0027] In actual use, by snapping the surface of the opening 14 onto the surface of the guide plate 10, and fixing the bottom surface of the guide plate 10 to the top surface of the pool body 1, the walkway frame 4 can move along the surface of the guide plate 10 on the top of the pool body 1. By fixing the bottom surface of the sealing cloth fixing plate 2 to the top surface of the pool body 1, and then fixing the end of the sealing cloth roll 8 to the inner surface of the sealing cloth fixing plate 2, the sealing cloth roll 8 seals the inside when the walkway frame 4 moves on the top of the pool body 1. By meshing the teeth of the gear 15 with the teeth of the tooth groove 11, the inside of the gear 15 is fixedly connected to the surface of the drive rod 16. When the servo motor 9 is started, the gear 15 rotates on the surface of the opening 14, so that the walkway frame 4 can automatically move along the guide plate 10 on the top of the pool body 1. The rotation of the drive rod 16 drives the drive pulley 17 to rotate through the transmission belt 18, which in turn drives the drive pulley 19 to rotate. This, in turn, drives the rotating rod 7 through the drive pulley 19, allowing the sealing cloth roll 8 to automatically rewind and expand. Thus, the walkway frame 4 can automatically rewind the sealing cloth roll 8 while moving on top of the pool body 1, allowing the sealing cloth roll 8 to cover the top of the pool body 1 and thus achieve a sealing effect on the top of the pool body 1. By fixing the surface of the opening 14 with a fixed support rod 13, and rotatably connecting the surface of the fixed support rod 13 to the inside of the guide wheel 12, when the walkway frame 4 moves on top of the pool body 1, the lowest end of the guide wheel 12 abuts against the top of the guide groove 3, providing support and guidance for the movement of the walkway frame 4.
