[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The term "plurality" means two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0019] The embodiments of the present application provide an urban underground pipeline dredging device, as Figure 1 shown. The urban underground pipeline dredging device includes a framework 200, a grille plate 100, and two connectors 300.

[0020] The framework 200 is in a shuttle shape and is adapted to the inner wall of the pipeline. Specifically, according to the diameter of the pipeline for which dredging work is required, the outer contour of the framework 200 is adapted to the diameter of the pipeline to ensure that the framework 200 can be placed in the pipeline and can move within the pipeline.

[0021] The grille plate 100 is located inside the framework 200 and is perpendicular to the length direction of the framework 200, and the edge of the grille plate 100 is connected to the middle of the framework 200. The grille plate 100 can push the waste in the pipeline to move and allows the water in the pipeline to flow through the through holes on the grille plate 100.

[0022] Exemplarily, the edge of the grille plate 100 is welded to the framework 200. Of course, the connection manner between the edge of the grille plate 100 and the framework 200 can also be bonding, bolt connection, etc.

[0023] The two connectors 300 are respectively connected to both ends of the framework 200. The connector 300 is used for fixing a rope, and then the rope pulls the urban underground pipeline dredging device.

[0024] Exemplarily, the two connectors 300 are respectively welded to both ends of the connecting framework 200. Of course, the connection manner between the two connectors 300 and both ends of the connecting framework 200 can also be bonding, bolt connection, etc.

[0025] When using the urban underground pipeline dredging device for pipeline dredging, place the urban underground pipeline dredging device in the pipeline. One end of the rope is connected to one of the connectors 300, and devices such as a winch are used to pull the rope, so that the urban underground pipeline dredging device moves in the pipeline. The shuttle-shaped framework 200 can pass through the sludge, sundries and other wastes in the pipeline, and the grid plate 100 pushes the wastes in the pipeline to the wellhead, and then the dredging personnel fish up the wastes through the wellhead. The urban underground pipeline dredging device can travel in small-diameter urban underground pipelines, thus realizing the dredging work of small-diameter urban underground pipelines, eliminating the need for manual dredging of small-diameter urban pipelines, and avoiding the occurrence of blockage and accumulation, thereby extending the service life of the pipeline. Moreover, the urban underground pipeline dredging device only needs to be pulled by a rope to complete the pipeline dredging work, and the use process is convenient and fast.

[0026] Of course, the urban underground pipeline dredging device can not only be applied to the dredging work of small-diameter pipelines, but by adjusting the sizes of the framework 200 and the grid plate 100, the urban underground pipeline dredging device can be applied to pipelines of various specifications.

[0027] It should be noted that the small-diameter pipelines mentioned in the embodiments of the present application include pipelines with specifications such as DN50, DN65, DN80, DN100, and DN150 in diameter.

[0028] Continue to refer to Figure 1 , the grid plate 100 is provided with installation through holes. The installation through holes are used to install high-pressure water guns. When the urban underground pipeline dredging device is performing dredging work, the dredging personnel can control the high-pressure water guns to open according to the situation in the pipeline to clean the inner wall of the pipeline.

[0029] In some embodiments of the present application, refer to Figure 1 and Figure 2 , the framework 200 includes a plurality of connecting rods 210. The plurality of connecting rods 210 are arranged in a circular array to form a shuttle-shaped structure. The connecting rod 210 includes two connecting sections 211. One ends of the two connecting sections 211 are connected and form an obtuse angle, and the other ends of the two connecting sections 211 are respectively connected to the two connectors 300. Among them, the edge of the grid plate 100 is connected to the connection part of the two connecting sections 211.

[0030] Exemplarily, one ends of the two connecting sections 211 are integrally connected, that is, the connecting rod 210 is a whole structure. Of course, one ends of the two connecting sections 211 can also be welded.

[0031] When the rope pulls the connector 300, the connecting rod 210 is subjected to a tensile force along its own length direction, and the connecting rod 210 has a strong ability to bear the tensile force in its own length direction, so that the above structure of the framework 200 can push more wastes.

[0032] Further, the framework 200 further includes a plurality of reinforcing rods 220. A reinforcing rod 220 is disposed between every two adjacent connecting rods 210, and two ends of the reinforcing rod 220 are respectively connected to the two adjacent connecting rods 210. The reinforcing rod 220 can increase the rigidity of the framework 200 and prevent the framework 200 from undergoing large deformation when moving in the pipeline.

[0033] Exemplarily, two ends of the reinforcing rod 220 are respectively welded to the two adjacent connecting rods 210. Of course, two ends of the reinforcing rod 220 can also be adhered to the two adjacent connecting rods 210.

[0034] It should be noted that the specific structure of the framework 200 is not limited to the above. In some other embodiments of the present application, the framework 200 can also be of other specific structures. For example, the framework 200 includes a plate material wound into a shuttle shape, and through holes for waste in the pipeline to pass through are provided on the plate material.

[0035] In some embodiments of the present application, referring to Figure 1 , the connector 300 includes a fixing cylinder 310 and a connecting ring 320. One end of the fixing cylinder 310 is connected to the end of the framework 200, and a connecting ring 320 is disposed at the other end of the fixing cylinder 310. The connecting ring 320 is used to fix the end of a rope, and the rope drives the urban underground pipeline dredging device to move in the pipeline through the connecting ring 320.

[0036] Exemplarily, the connecting ring 320 is welded to the end of the fixing cylinder 310 far from the framework 200. Of course, the connection manner between the connecting ring 320 and the fixing cylinder 310 can also be adhesion, bolt connection, etc.

[0037] Further, free ends of the two connecting segments 211 are respectively connected to the outer circumferential surfaces of the two fixing cylinders 310. Taking the orientations in Figure 1 and Figure 2 as an example, the free end of the left connecting segment 211 refers to the left end of the left connecting segment 211, and the free end of the right connecting segment 211 refers to the right end of the right connecting segment 211.

[0038] It should be noted that the specific structure of the connector 300 is not limited to the above. In some other embodiments of the present application, the connector 300 can also be of other specific structures. For example, the connector 300 is a hook, and the hook is connected to the end of the framework 200.

[0039] Exemplarily, free ends of the two connecting segments 211 are respectively welded to the outer circumferential surfaces of the two fixing cylinders 310. Of course, free ends of the two connecting segments 211 can also be bolt-connected or welded to the two connecting cylinders respectively.

[0040] The various embodiments in this specification are described in a progressive manner. For the same or similar parts among the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
