Description
Technical Field
[0001] The utility model relates to the field of rainwater inlet filtering devices, and more specifically, to a rainwater inlet filtering device for municipal engineering. Background Technique
[0002] The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering. In municipal engineering, rainwater inlets are facilities that collect surface water in the pipeline drainage system. There are many rainwater inlets in the city. These rainwater inlets mainly drain the rainwater on the road in time to avoid the accumulation of rainwater affecting normal traffic. During the process of rainwater flowing on the ground, a large amount of impurities are carried. When discharging rainwater through the rainwater inlet, a filtering device needs to be installed at the rainwater inlet to intercept the leaves and sundries in the rainwater.
[0003] However, there are some problems in the actual working process of the existing rainwater inlet filtering devices for municipal engineering. For example, a rainwater inlet filtering device for municipal engineering with the publication number of CN220715054U can perform multi-stage filtration of rainwater during its working process. However, during the long-term working process, it cannot automatically gather the filtered sundries. Therefore, the filtered sundries are extremely easy to accumulate on the filter screen, resulting in the blockage of the filter screen, affecting the normal discharge of rainwater, and leading to the generation of water accumulation, with poor practicability. And the existing rainwater inlet filtering devices for municipal engineering cannot be disassembled and installed conveniently and stably during the actual working process, and thus cannot ensure the convenience of its subsequent cleaning work. Therefore, we make improvements and propose a rainwater inlet filtering device for municipal engineering. Summary of the Utility Model

[0034] Embodiment 2:
[0035] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details:
[0036] As Figures 4-6 shown, as a preferred embodiment, on the basis of the above method, further, the side end surface of the rainwater plate 3 fits with the inner wall of the drainage well 1. The water inlet grooves 4 are evenly distributed on the drainage well 1. The storage grooves 5 are symmetrically distributed on both sides of the rainwater plate 3. The storage grooves 5 correspond to the connection frames 6 one by one. The side end surface of the connection frame 6 fits with the inner wall of the storage groove 5. The traction rope 9 is slidably connected in the rainwater plate 3. The clamping block 10 is slidably connected in the rainwater plate 3. The connection frames 6 and the clamping blocks 10 correspond to each other through the traction ropes 9. The clamping blocks 10 and the first clamping grooves 2 correspond to each other one by one. The cross-section of the first clamping groove 2 and the cross-section of the end of the clamping block 10 are both right trapezoids. The rubber plates 8 are symmetrically distributed on both sides of the pull rod 7. The rubber plates 8 fit with the inner wall of the connection frame 6. By using the cooperation of the first clamping groove 2 and the clamping block 10, the clamping installation and disassembly separation of the rainwater plate 3 can be conveniently completed. After the rainwater plate 3 is disassembled, the disassembly of the first filter screen frame 12 can be conveniently completed, and then the subsequent overall disassembly and cleaning work of the filtering device can be carried out.
[0037] As Figures 3-5As shown, as a preferred embodiment, on the basis of the above method, further, a second spring 14 is welded and fixed to the top surface of the limit frame 13. The top end of the second spring 14 is welded and fixed with a clamping rod 15. The clamping rod 15 is slidably connected in the limit frame 13. A second clamping groove 17 is formed on the filter screen plate 16. The bottom end of the clamping rod 15 is clamped and connected in the second clamping groove 17. The clamping rod 15 is connected to the middle part of the limit frame 13. By using the cooperation of the clamping rod 15 and the second clamping groove 17, the filter screen plate 16 can be conveniently and stably clamped and installed and disassembled and separated. By disassembling the filter screen plate 16, the sundries collected inside each second filter frame 18 can be transported and cleaned, and thus the subsequent cleaning work of the whole filtering device can be conveniently completed.
[0038] As Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the filter screen plate 16 is inclined. The second filter frames 18 are equidistantly distributed on the filter screen plate 16. The top surface of the filter screen plate 16 is flush with the top surface of the second filter frames 18. The filter screen plate 16 can be used to filter rainwater. Under the action of its own gravity, the filtered sundries can roll along the inclined surface of the filter screen plate 16, and then roll into the second filter frames 18 for automatic collection. The filtered rainwater can be conveyed downward from other parts of the filter screen plate 16, and thus it can effectively prevent the filtering device from being completely blocked due to excessive filtered sundries, affecting the subsequent drainage work.
[0039] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the fixed pipe 19 is connected to the bottom center of the drainage well 1. The inner wall of the drainage well 1 is in contact with the outer wall of the first filter frame 12. The spiral rod 20 can form a spiral diversion channel. The spiral diversion channel can be used to drain rainwater in a spiral manner, prevent the water flow from blocking the pipeline due to inertia, improve the drainage efficiency, and reduce the occurrence of blockage accidents.
[0040] Specifically, when the rainwater inlet filtering device of this municipal engineering is in use: During the operation of the rainwater inlet filtering device, when the drainage well 1 drains rainwater, the rainwater enters the drainage well 1 through the water inlet groove 4 on the rainwater plate 3, and the sundries on the road also enter the drainage well 1 through the rainwater. At this time, the rainwater first contacts the first layer of filter screen plate 16. Under the action of the first layer of filter screen plate 16, the rainwater can be filtered. Under the action of its own gravity, the filtered sundries can roll along the inclined surface of the filter screen plate 16 and then roll into the second filter screen frame 18 for automatic collection. After the front second filter screen frame 18 is full, the sundries can roll into the next second filter screen frame 18 for automatic collection. Similarly, after the second filter screen frame 18 on the first layer of filter screen plate 16 is full, the sundries can roll onto the second layer of filter screen plate 16 for continuous collection. By using the cooperation of the upper and lower layers of filter screen plates 16 and each second filter screen frame 18, the filtered sundries can be automatically and centrally collected, and the filtered rainwater can be transported downward from other parts of the filter screen plate 16, thus effectively avoiding the complete blockage of the filtering device caused by too many filtered sundries and affecting the subsequent drainage work;
[0041] After the rainwater is filtered, it can be transported to the fixed pipe 19 through the first filter screen frame 12. The spiral rod 20 in the fixed pipe 19 can form a spiral diversion channel. By using the spiral diversion channel, the rainwater can be drained in a spiral manner, preventing the water flow from blocking the pipe due to inertia, improving the drainage efficiency, reducing the occurrence of blockage accidents, and then the rainwater can be discharged through the drain pipe 21;
[0042] After the filtering device finishes working, the staff can use their fingers to push aside the rubber plates 8 on both sides of the pull rod 7 and insert them into the connecting frame 6. Then, by pulling the pull rod 7, the connecting frame 6 can be driven to move upward. At this time, under the movement of the two connecting frames 6 on both sides, the two clamping blocks 10 can be pulled to move towards the middle simultaneously through the traction rope 9 and disengage from the first clamping groove 2. At this time, by continuing to pull the connecting frame 6 upward, the rainwater plate 3 can be pulled to move out of the drainage well 1, and the disassembly of the rainwater plate 3 can be conveniently completed. After the rainwater plate 3 is disassembled, the staff can grasp the first layer of filter screen plate 16 and pull the first filter screen frame 12 upward until the first filter screen frame 12 moves out of the drainage well 1, and the disassembly of the first filter screen frame 12 can be completed. Subsequently, the staff can pull the clamping rod 15 on the limit frame 13 upward until the clamping rod 15 moves out of the second clamping groove 17 on the filter screen plate 16, and the disassembly work of the filter screen plate 16 can be conveniently completed. After the first layer of filter screen plate 16 is disassembled, through the same operation, the second layer of filter screen plate 16 can be disassembled. By disassembling the filter screen plate 16, the sundries collected inside each second filter screen frame 18 can be transported and cleaned, and then the subsequent cleaning work of the entire filtering device can be conveniently completed;
[0043] After the filtering device is disassembled and cleaned, the staff can pull up the latch 15 on the limit frame 13 again, and snap one end of the filter screen plate 16 into the limit frame 13. Then, the latch 15 can be released. At this time, under the elastic action of the second spring 14, the latch 15 can be driven to automatically snap into the second card slot 17 on the filter screen plate 16, completing the snap-in installation of the filter screen plate 16. Then, the staff can put the first filter screen frame 12 into the drainage well 1. After the first filter screen frame 12 is placed stably, the staff can place the rainwater plate 3 above the drainage well 1. At this time, the inclined surfaces at the ends of the clamping blocks 10 on both sides of the rainwater plate 3 are in contact with the drainage well 1. Then, the staff presses down the rainwater plate 3. Under the pressing action of the rainwater plate 3, the clamping blocks 10 on both sides can be pushed to automatically move into the rainwater plate 3 until the clamping blocks 10 move to the first card slot 2. At this time, under the elastic action of the first spring 11, the clamping blocks 10 can be driven to automatically snap into the first card slot 2 on the drainage well 1, completing the snap-in installation of the rainwater plate 3, thereby ensuring the stability of the subsequent working state of the filtering device.
[0044] The above embodiments are only used to illustrate the present invention and not to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the utility model are covered by the scope of the claims of the present invention.
