Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a municipal engineering pipeline drainage dredging device. Background Art

[0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns, and provide paid or free public products and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls within the scope of municipal engineering. Unclogging blocked drainage pipes is one of the tasks that needs to be performed frequently.

[0003] The prior art proposes a Chinese patent with publication number CN212835867U. The technical solution disclosed in the patent document is as follows: a dredging device for municipal engineering drainage pipes. Although the prior art solves the problem that most of the existing dredging devices for municipal engineering drainage pipes use a drill to clear the blockage during the dredging process, the blocked foreign matter cannot be removed, which causes the pipe to be blocked.

[0004] However, the above-mentioned prior art still has some shortcomings during use. For example, when the municipal pipeline is blocked, some hard debris such as branches and leaves will be stuck on the inner wall of the pipeline, hindering the fixed tube from being pulled out. After applying force to pull it out, it may become tighter and more difficult to clean, affecting the overall dredging efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a municipal engineering pipeline drainage dredging device, including a cleaning barrel 1 and an outer sleeve 2, the interior of the cleaning barrel 1 is rotatably connected to an internal threaded rotating rod 3, the outer wall of one end of the internal threaded rotating rod 3 is threadedly connected to a threaded inner ring 13, the outer wall of the threaded inner ring 13 is fixedly connected to an outer ring 6 through a connecting rod 10, one side of the outer ring 6 is rotatably connected to a deflection cleaning rod 8 through a shaft seat, and the other side of the outer ring 6 is fixedly connected to a parallel cleaning rod 9.

[0028] The outer wall of the cleaning cylinder 1 is provided with a guide groove 7 for the sliding of the connecting rod 10, an inclined surface at one end of the outer sleeve 2 is provided with an inclined hole 4 for docking with the deflected cleaning rod 8, and the other end of the outer sleeve 2 is provided with a parallel hole 5 for docking with the parallel cleaning rod 9, and the outer ring 6 is located inside the outer sleeve 2.

[0029] Example 2

[0030] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the outer wall of the end of the deflection cleaning rod 8 away from the outer ring 6 is slidably connected to the inner wall of the inclined hole 4, and the deflection cleaning rod 8 and the parallel cleaning rod 9 are respectively distributed in a circular array on both sides of the outer ring 6. The deflection cleaning rod 8 is restricted by the shaft seat when it is not extended outward, and the extension line of the axis is on the same axis as the parallel cleaning rod 9.

[0031] The inner wall of the outer collar 6 is slidably connected to the outer wall of the cleaning tube 1, and the inner wall of the guide slot 7 is slidably connected to the outer wall of the connecting rod 10. When the outer collar 6 moves on the outer wall of the cleaning tube 1, the connecting rod 10 slides on the inner wall of the guide slot 7 to guide and limit the movement of the outer collar 6, so that the deflected cleaning rod 8 and the parallel cleaning rod 9 can accurately dock with the oblique hole 4 and the parallel hole 5, which is convenient for subsequent cleaning work.

[0032] The outer wall of the outer ring 6 is slidably connected to the inner wall of the outer sleeve 2, the outer wall of one end of the inner threaded rotating rod 3 is rotatably connected to the inner wall of one end of the cleaning tube 1 through the threaded rod shaft ring 12, and the other end of the inner threaded rotating rod 3 is rotatably connected to the other end of the cleaning tube 1.

[0033] One end of the built-in threaded rotating rod 3 is fixedly connected to a threaded rod rotating disk 11 , and one end of the cleaning cylinder 1 is fixedly connected to a cleaning rotating disk 14 .

[0034] The following is a detailed description of the working principle of the municipal engineering pipeline drainage dredging device.

[0035] like Figure 1-5 As shown, when in use, insert one end of the cleaning tube 1 with the drill bit into the drain pipe to be dredged, and then rotate the cleaning turntable 14, so that the cleaning tube 1 first drills into the blockage through the drill bit. When the forward resistance is too large, the built-in threaded rotating rod 3 is rotated at this time, so that the built-in threaded rotating rod 3 drives the threaded inner ring 13 through the outer wall thread connection and starts to move in the direction of the drill bit. Then the threaded inner ring 13 drives the outer ring 6 to move forward through the connecting rod 10, and the outer ring 6 drives the parallel cleaning rod 9 to insert into the parallel hole 5 and protrude from the front end of the outer sleeve 2. Since the front end of the parallel cleaning rod 9 is a cone-top structure, it can be quickly inserted into the blockage, and then the cleaning turntable 14 is rotated again, so that the cleaning turntable 14 drives the cleaning tube 1 to rotate, and the cleaning tube 1 drives the parallel cleaning rod 9 to rotate through the outer sleeve 2. The parallel cleaning rod 9 can stir the blockage together during the rotation process, and crush the branches and leaves, etc., and then the cleaning tube 1 is pulled out of the pipeline, so that part of the blockage can be cleaned.

[0036] When the cleaning cylinder 1 can penetrate the blockage, the built-in threaded rotating rod 3 can be reversed. At this time, the outer collar 6 will move toward the tail end of the built-in threaded rotating rod 3. At this time, the outer collar 6 will push the deflected cleaning rod 8 to dock with the oblique hole 4. Then, under the guidance of the oblique hole 4, it begins to unfold in a ring-shaped outward state and insert into the blockage. Finally, the cleaning cylinder 1 is rotated, and the deflected cleaning rod 8 is used to stir the blockage. Then, the cleaning cylinder 1 is pulled outward to clean the blockage out of the pipeline.

[0037] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the utility model. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
