[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] Example:

[0028] Reference Figures 1 to 5 This embodiment proposes a drainage pipe for municipal roads, including an inlet pipe 2, an outlet pipe, and a filter section 3 disposed between the inlet pipe 2 and the outlet pipe; the filter section 3 includes a foldable filter structure, which folds to form a zigzag configuration when clogged, so that the blockage is compressed by the filter structure during the folding process. Figure 1As shown, the top of the inlet pipe 2 can generally be equipped with an inlet mounting part 1 to connect the pipe to the road drainage ditch or drainage well cover, and the cover installed at the drainage ditch generally has a preliminary filtering function. The outlet pipe can be equipped with an outlet mounting part 4 to connect to the subsequent drainage pipe. Generally, the amount of garbage entering the filter part 3 after passing through the cover is relatively small, so the frequency of clogging is generally not too high. However, when clogging occurs after long-term use, the clogging will cause water to accumulate around the filter part 3, and the accumulated water is generally quite turbid, making it difficult to clear the blockage. Unlike the prior art, this embodiment can first fold the filter structure, so that the blockage at the filter structure moves with the fold and is finally compressed. The folding is generally done with one side stationary, and the folded end is moved away from its original position, forming an opening that allows water to flow through. However, this operation may cause subsequent pipe blockage, so this operation is suitable for situations with less blockage. This embodiment can also restore the folded structure to its original state after folding. After the blockage is compressed by folding, it is obviously able to pass through water compared to before. After the sewage is drained, the blockage can be cleaned according to the blockage situation. Compared to existing technologies, this embodiment can quickly and temporarily remove blockages when they occur, and then perform the unblocking work after the sewage has been drained.

[0029] like Figure 4 As shown, the preferred filter structure rotates from the middle when folded, forming a sharp-angled zigzag shape. In one embodiment, the filter structure can be folded to directly form a channel for drainage; in this case, the fold is made directly at an acute angle, as shown in the reference [reference needed]. Figure 5 As shown, when the water flows through, it is less likely to carry the folded and compressed blockage into the channel, thus effectively preventing subsequent pipe blockage.

[0030] To further enhance the filtration effect, such as Figure 4 As shown, the filter section 3 also includes a filter plate 7, which is located behind the filter structure. This ensures that even after the filter structure is folded, regardless of whether the folded structure is restored, blockages are less likely to directly enter subsequent pipes and cause congestion.

[0031] like Figure 2 , Figure 3 As shown, a filter chamber 12 is formed inside the filter section 3. The filter structure and the filter plate 7 are spaced apart, and the filter mesh of the filter structure and the filter plate 7 is partially or completely staggered so that a slow flow area is formed between the filter structure and the filter plate 7, thereby preventing some impurities from passing directly through the filter mesh when the flow rate is too fast.

[0032] like Figure 4 , Figure 5As shown, the filter structure includes a fixed plate 14, a movable plate 13, and a rotating shaft 10. The movable plate 13 and the rotating shaft 10 are fixedly installed, and the rotating shaft 10 is hingedly installed in the inner cavity of the filter section 3. The top of the rotating shaft 10 passes through and extends out of the top of the filter section 3 to form a rotation adjustment section 5. Both the fixed plate 14 and the movable plate 13 are semi-circular plates, and the radius of the movable plate 13 is smaller than the radius of the corresponding position in the inner cavity of the filter section 3. The fixed plate 14 is fixedly installed in the inner cavity of the filter section 3, and the movable plate 13 is hingedly installed with the rotating shaft 10. The rotating shaft 10 is provided with a damping structure to increase rotational resistance. In the initial state, the fixed plate 14 and the movable plate 13 are... Figure 4 As shown, the two are at 180°, and after folding, they are as follows: Figure 5 As shown, the folding angle is greater than 90°, thus forming an acute angle. Since the movable plate 13 needs to rotate within the inner cavity of the filter section 3, it is preferable that the radius of the movable plate 13 is slightly smaller than the radius of the inner cavity of the filter section 3 at the corresponding position; otherwise, the movable plate 13 may be blocked by the inner cavity of the filter section 3 when rotating.

[0033] like Figures 3 to 5 As shown, since the radius of the movable plate 13 is slightly smaller than the pipe wall at the corresponding position, in order to ensure the sealing at the edge during normal filtration, a sealing ring 11 is fixedly installed in the inner cavity of the filter section 3. The sealing ring 11, the fixed plate 14 in the initial state, and the edge of the movable plate 13 are fitted together to form a seal.

[0034] like Figure 4 As shown, a sealing part 15 is provided at the position where the rotating shaft 10 and the top of the filter section 3 meet. The sealing part 15 is made of rubber and is fixedly installed on the filter section 3. The rotating shaft 10 passes through the center of the sealing part 15, and the rotating shaft 10 and the sealing part 15 form an interference fit. A bearing 9 is provided on the outer side of the top of the rotating shaft 10. The bearing 9 is a sealed bearing and is fixedly installed on the filter section 3. When the rotating shaft 10 rotates, the movable plate 13 can rotate. The bearing 9 facilitates the stable rotation of the rotating shaft 10 in its original position, and the sealing part 15 reduces rotational resistance and ensures a seal at the connection point during rotation.

[0035] Preferably, the rotation adjustment part 5 is a hexagonal nut, which can be rotated by a maintenance personnel using a hexagonal wrench of the corresponding size; alternatively, a handle 6 is fixedly provided on the outside of the rotation adjustment part 5, which can be used for direct adjustment. A suitable solution can be selected based on the actual installation environment.

[0036] To facilitate the installation of the inlet pipe 2 and the outlet pipe, the filter section 3 is provided with mounting threads 8 on both sides. The inlet pipe 2 and the outlet pipe are installed through the mounting threads 8, and a sealing ring is provided at the installation point to increase the sealing performance.

[0037] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
