Description

Technical Field

[0001] This utility model relates to the field of road drainage pipe network construction technology, and in particular to a filter structure for road drainage pipe network construction. Background Technology

[0002] An existing filter structure for urban road drainage network construction, with publication number CN 221481016 U, first blocks larger debris washed into the drainage pipe by a filter screen when rainwater enters. Then, it further filters through a filter screen to remove remaining debris. A motor I provides power, driving a scraper along the filter screen via a rotating shaft. This scraper cleans debris from the filter screen, preventing clogging and ensuring normal water discharge. Simultaneously, the rotating shaft drives a reciprocating screw, which in turn moves a threaded sleeve along a limiting rod. This movement, via a connecting plate and a ring, moves spikes that insert into the filter screen, removing debris that clogs the screen and further preventing clogging and ensuring normal water discharge. However, this device requires a motor for power, increasing the complexity of the overall structure and maintenance costs in practical use. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a filter structure for road drainage pipe network construction in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A filter structure for road drainage network construction includes a grate plate installed at the upper end of a drainage pipe, a filter mechanism installed inside the drainage pipe, and a filter plate installed inside the drainage pipe below the grate plate. A support frame is fixed on the inner wall of the drainage pipe below the filter plate, and a support ring is provided between the support frame and the filter plate. The filter plate moves up and down relative to the support ring. A cleaning component is provided on the support frame to clean the upper part of the filter plate during its up and down movement. The cleaning component includes a fixed cylinder fixed at the center of the support frame, a spiral groove provided on the inner wall of the fixed cylinder, a support rod passing through the upper end of the fixed cylinder, a rotating disk fixed inside the fixed cylinder at the lower end of the support rod, a sliding column that cooperates with the spiral groove fixed on the side wall of the rotating disk, a flange provided on the outer diameter of the support rod below the filter plate, a scraper installed through the filter plate at the upper end of the support rod, and an elastic component provided between the lower end of the filter plate and the support ring.

[0006] Further configuration: The elastic component includes a guide post circumferentially fixed to the lower end of the filter plate, with a top cap provided at the lower end of the guide post passing through the support ring, and a spring sleeved on the outer diameter of the guide post above the support ring.

[0007] Further configuration: A tapered nail corresponding to the leakage hole on the filter plate is fixed at the upper end of the support ring; the guide post is slidably connected to the support ring; and the filter plate is slidably connected to the drain pipe.

[0008] Further details: A suction pipe is connected to the outer wall of the drain pipe on the upper side of the support ring.

[0009] Further configuration: The support rod is rotatably connected to the fixed cylinder and filter plate, and the support rod can slide up and down on the fixed cylinder and support ring.

[0010] Further setting: The scraper is tangent to the upper surface of the filter plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] During different stages of rainwater filtration, the filter plate of the filtration mechanism moves up and down under the support of the elastic component. The support rod moves with the filter plate, and the sliding column on the rotating disk at the lower end of the support rod cooperates with the spiral groove in the fixed cylinder to rotate, causing the rotating disk and the support rod to rotate as a whole. This drives the scraper at the upper end of the support rod to rotate and concentrate the impurities on the filter plate. When the filter plate moves to the bottom, the conical nail on the support ring pushes out the impurities in the filter holes of the filter plate, so that the filter plate can clean the filtered impurities without external power, thus improving the overall structural performance.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a filter structure for road drainage network construction includes a grate 11 installed at the upper end of the drainage pipe 1, and a filter mechanism installed inside the drainage pipe 1.

[0024] In this embodiment: the filtration mechanism includes a filter plate 26 disposed inside the drain pipe 1, located below the grate 11. A support frame 12 is fixed on the inner wall of the drain pipe 1, located below the filter plate 26. A support ring 28 is disposed between the support frame 12 and the filter plate 26. The filter plate 26 moves up and down relative to the support ring 28. A cleaning component is disposed on the support frame 12 to clean the upper side of the filter plate 26 during the up and down movement of the filter plate 26. An elastic component is disposed between the lower end of the filter plate 26 and the support ring 28. A suction pipe 212 is connected to the outer wall of the drain pipe 1, located above the support ring 28. A suction device is externally connected to the upper end of the suction pipe 212. This is the prior art disclosed and will not be described in detail here.

[0025] The cleaning assembly includes a fixed cylinder 21 fixed at the center of the support frame 12. A spiral groove 201 is provided on the inner wall of the fixed cylinder 21. A support rod 22 passes through the upper end of the fixed cylinder 21. A rotating disk 23 is fixed inside the fixed cylinder 21 at the lower end of the support rod 22. A sliding column 24 that mates with the spiral groove 201 is fixed on the side wall of the rotating disk 23. A flange 25 is provided on the outer diameter of the support rod 22 below the filter plate 26. A scraper 27 is installed at the upper end of the support rod 22, passing through the filter plate 26. The support rod 22 is rotatably connected to the fixed cylinder 21 and the filter plate 26, and can slide up and down on the fixed cylinder 21 and the support ring 28. 7 is tangent to the upper end face of the filter plate 26. As the filter plate 26 moves up and down, the support rod 22 moves with the filter plate 26. The sliding column 24 on the rotating disk 23 at the lower end of the support rod 22 cooperates with the spiral groove 201 in the fixed cylinder 21 to rotate, so that the rotating disk 23 and the support rod 22 rotate as a whole, driving the scraper 27 at the upper end of the support rod 22 to rotate and concentrate the impurities on the filter plate 26. When the filter plate 26 moves to the lowermost side, the conical nail 211 on the support ring 28 pushes out the impurities in the filter holes of the filter plate 26, and the impurities are drawn upward through the suction pipe 212. Then the filter plate 26 returns to its original position.

[0026] The elastic component includes a guide post 29 circumferentially fixed to the lower end of the filter plate 26. The lower end of the guide post 29 passes through the support ring 28 and is provided with a top cap. A spring 210 is sleeved on the outer diameter of the guide post 29 on the upper side of the support ring 28. A tapered nail 211 corresponding to the leakage hole on the filter plate 26 is fixed at the upper end of the support ring 28. The guide post 29 is slidably connected to the support ring 28, and the filter plate 26 is slidably connected to the drain pipe 1. When too many impurities accumulate on the filter plate 26, the speed of rainwater passing through the filter plate 26 slows down, and the amount of rainwater on the filter plate 26 increases. The filter plate 26 is pressed downward under the limit of the guide post 29. When the rainwater flows normally through the filter plate 26, the spring 210 pushes the filter plate 26 to move upward and reset.

[0027] The working principle and usage process of this utility model: Rainwater enters the drain pipe 1 through the grate 11, and after being filtered again by the filter plate 26, it enters the main pipe. When too many impurities accumulate on the filter plate 26, the speed at which the rainwater passes through the filter plate 26 slows down, and the amount of rainwater on the filter plate 26 increases. This causes the filter plate 26 to be pressed downward under the limit of the guide post 29, causing the filter plate 26 to move downward. At the same time, as the support rod 22 moves downward with the filter plate 26, the sliding post 24 on the rotating disk 23 at the lower end of the support rod 22 and the U-shaped groove inside the fixed cylinder 21... The spiral groove 201 rotates, causing the rotating disk 23 and the support rod 22 to rotate as a whole. This causes the scraper 27 at the upper end of the support rod 22 to rotate, concentrating the impurities on the filter plate 26. The impurities are then drawn upwards through the suction pipe 212. When the filter plate 26 moves to the bottom, the conical nail 211 on the support ring 28 pushes out the impurities in the filter holes of the filter plate 26, allowing rainwater to pass through smoothly. After the rainwater passes through, once the pressure of the rainwater is less than the force of the spring 210, the spring 210 pushes the filter plate 26 upwards as a whole.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
