Technical Field

[0001] This utility model relates to the technical field of water inlet pump room equipment, specifically a quick-replacement structure for water inlet pump room filters. Background Technology

[0002] The intake pump station is an important infrastructure in water treatment systems, water supply systems and other fields. Its main function is to transport external water sources (such as river water, lake water, groundwater, etc.) to subsequent treatment units or water terminals. In order to prevent impurities in the water (such as silt, floating objects, stones, etc.) from entering the pump and causing wear, blockage or damage to the pump, filter screen components are usually installed in the intake pipe of the intake pump station to filter the incoming water.

[0003] However, the filter components in traditional water inlet pump stations are usually installed inside the water inlet pipe using flange connections or bolt fixation. When the filter needs to be cleaned or replaced after a period of use, the operator must first close the water inlet valve to cut off the water supply, then use tools to remove the flange bolts or fixing bolts, remove the filter for maintenance, and then reinstall and tighten the bolts after maintenance. This replacement method has the following problems: First, the replacement process is cumbersome, requires the use of professional tools, and the bolt removal and installation are time-consuming, especially for large-diameter water inlet pipes, where the maintenance time is even longer; Second, the long disassembly and assembly time leads to extended equipment downtime, reducing water supply or water treatment efficiency, which has a more significant impact on scenarios with high continuous operation requirements (such as urban water supply pump stations and industrial circulating water systems).

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figures 1-7 .

[0017] The quick-replacement structure for the inlet pump room filter includes a support frame 1 and external connecting pipes 2 and a pump room inlet pipe 20, which are respectively fixedly installed on both sides of the support frame 1. The external connecting pipes 2 are used to connect to an external water inlet system, and the pump room inlet pipe 20 smoothly delivers water into the pump room. Corrugated pipes 3 are fixedly installed at the ends of the external connecting pipes 2 and the pump room inlet pipe 20 that are close to each other. Connecting pipes 4 are fixedly installed at the ends of the two corrugated pipes 3 that are close to each other. A common filter sleeve 5 is provided between the two connecting pipes 4, and a filter screen 6 is fixedly installed inside, thus forming a filter assembly. Sealing rings are fixedly installed on both sides of the filter sleeve 5, and the two sealing rings respectively fit against the ends of the two connecting pipes 4 to ensure the smooth flow of the entire pipeline. Sealing performance: Four connecting strips 10 are fixedly installed on the outer ring wall of each of the two connecting pipes 4. Each of the eight connecting strips 10 has a guide hole 11. Two connecting rings 7 are fixedly installed on the outer ring wall of the filter sleeve 5. Four guide posts 8 are fixedly installed on the side of the two connecting rings 7 that are far apart from each other. The ends of the eight guide posts 8 are all spherical. Each of the eight guide posts 8 passes through the corresponding guide hole 11 and fits against the inner wall of the corresponding guide hole 11. By utilizing the cooperation between the guide posts 8 and the guide holes 11, the operator can easily install and position the filter sleeve 5. Each of the eight guide posts 8 has a fitting groove 9. The outer ring wall of the two connecting pipes 4 is provided with a fitting mechanism, which is adapted to the fitting groove 9.

[0018] Each of the aforementioned inserting mechanisms includes a rotating sleeve 19 and four hollow positioning posts 14. The rotating sleeve 19 is threaded onto the connecting pipe 4, and the four hollow positioning posts 14 are fixedly installed on their respective connecting pipes 4. Each of the four hollow positioning posts 14 has an opening on the side furthest from the connecting pipe 4. Each of the four hollow positioning posts 14 contains a first wedge block 17, which is adapted to the spherical end of the corresponding guide post 8. The wedge and spherical surfaces work together to create a contact effect. Each of the four hollow positioning posts 14 also contains a linkage arm 15, one side of which extends out of the corresponding hollow positioning post 14 and slides through it. This sliding connection is achieved by opening a [missing information - likely a specific opening on one side of each hollow positioning post 14]. The system is implemented with a second adapter slide, and all four linkage arms 15 pass through the corresponding second adapter slide and fit against the inner wall of the corresponding second adapter slide, thus giving the linkage arm 15 a sliding space. One end of the return spring 16 is fixedly installed in each of the four hollow positioning posts 14, and the other end of each of the four return springs 16 is fixedly connected to the corresponding linkage arm 15. A second wedge block 18 is fixedly installed on the side of each of the four linkage arms 15 outside the hollow positioning posts 14. The side of the rotating cover 19 near the second wedge block 18 is set as an arc surface. The second wedge block 18 is adapted to the arc surface of the rotating cover 19. By utilizing the cooperation between the wedge surface and the arc surface, the two can form a resisting effect. In addition, multiple rotating handles are fixedly installed on the outer ring wall of the rotating cover 19 for easy manual operation by the operator.

[0019] In this embodiment, when the filter sleeve 5 is removed, in order to allow the guide post 8 to be pulled out from the guide hole 11, two electric push rods 12 are fixedly installed on the top of the support frame 1. Push arms 13 are fixedly installed on the output shafts of the two electric push rods 12. The bottom of the two push arms 13 passes through the support frame 1 and is fixedly connected to the corresponding connecting pipe 4. The two push arms 13 are slidably connected to the support frame 1. This slidable connection is achieved by opening two first adapting slides on the top of the support frame 1. The two push arms 13 pass through the two first adapting slides respectively, and the two push arms 13 are respectively attached to the inner wall of the two first adapting slides.

[0020] The working principle of the quick-replacement structure for the inlet pump room filter provided by this utility model is as follows: When the filter sleeve 5 needs to be removed, cleaned or replaced, first rotate one of the rotating sleeve covers 19. When its arc surface contacts the corresponding four second wedge blocks 18, it will push the corresponding four second wedge blocks 18, causing the corresponding four linkage arms 15 to move closer to the axis. Under the traction of the linkage arms 15, the corresponding four first wedge blocks 17 will move synchronously and finally completely disengage from the slots 9 on the guide post 8. At this point, the locking restriction of the four guide posts 8 on this side is officially removed. Subsequently, in the same manner as above, the other four first wedge blocks 17 are brought out of the corresponding slots 9, so that the restriction effect of the other set of four guide posts 8 is released. This is an operation in two steps, or it can be operated synchronously by rotating the two rotating sleeves 19. Then, the filter sleeve 5 is lifted up and the two electric push rods 12 are activated. The output shafts of the two electric push rods 12 gradually extend, causing the two push arms 13 to move away from each other. Finally, the eight guide posts 8 are separated from the corresponding connecting strips 10. At the same time, the two connecting tubes 4 are also separated from the filter sleeve 5. Then the filter sleeve 5 can be removed for cleaning or replacement. After that, the two rotating sleeve covers 19 are rotated in the opposite direction to separate the rotating sleeve covers 19 from the second wedge block 18. When installing the filter sleeve 5, simply align four of the guide posts 8 with the guide holes 11 on the corresponding connecting strips 10 and insert them. During insertion, the spherical end of the guide post 8 will contact the corresponding first wedge block 17, thus creating resistance and causing it to retract into the hollow positioning post 14. At this time, the return spring 16 is compressed until the first wedge block 17 aligns with the insertion groove 9. The compressed return spring 16 releases its elasticity, directly bringing the first wedge block 17 into the insertion groove 9, creating a locking effect. The sealing ring on one side of the filter sleeve 5 also contacts the corresponding connecting pipe 4. Then, the output shafts of the two electric push rods 12 are retracted, and the two connecting pipes 4 move closer to each other, inserting the other four guide posts 8 into the corresponding guide holes 11 and engaging with the corresponding first wedge blocks 17. Finally, the four first wedge blocks 17 are inserted into the corresponding insertion grooves 9, thus completing the installation of the filter sleeve 5.

[0021] Compared with related technologies, the quick-replacement structure for the inlet pump room filter provided by this utility model has the following beneficial effects: I. This utility model can unlock the locking mechanism by rotating the rotating sleeve cover 19, and automatically separate the connecting pipe 4 and the filter sleeve 5 with the electric push rod 12. No complicated tools are required, the constraint of the filter sleeve 5 can be quickly released, the disassembly time can be shortened, the equipment downtime can be greatly reduced, the adverse effects on water supply can be greatly reduced, and the water supply efficiency can also be improved. Second, this utility model only requires inserting the four guide posts 8 on one side into the corresponding guide holes 11, and then using the electric push rod 12 to achieve the quick assembly of the connecting tube 4 and the filter sleeve 5, which provides greater convenience for the operator. Third, in this utility model, the disassembly and installation process is clear and has no complicated technical requirements, which makes it easy for staff to master quickly, reduces the difficulty of operation and maintenance, and is suitable for the daily efficient operation and maintenance needs of the water intake pump room.
