Description

Technical Field

[0001] The utility model relates to the field of municipal engineering equipment, and more specifically, to a municipal pipeline cleaning device. Background Art

[0002] With the acceleration of the urbanization process, the importance of municipal infrastructure, especially the underground drainage system, has become increasingly prominent. The underground drainage pipeline is an indispensable part of urban infrastructure, which is related to multiple aspects such as urban flood control and drainage, sewage treatment, and environmental protection. However, due to various solid wastes and sediments contained in the sewage, municipal pipelines are prone to blockage, which not only affects the drainage efficiency of the pipelines but also may cause environmental pollution and public health problems.

[0003] During the rainy season, a large number of branches and other solid wastes will be washed to the pipeline well. After a large amount of accumulation, some sludge will be blocked at the pipeline well, which will seriously affect the normal drainage. Therefore, it is necessary to timely clean the solid wastes remaining at the pipeline well.

[0004] The traditional manual cleaning method is to manually fish, which is time-consuming and inefficient, and cannot meet the maintenance needs of large-scale municipal pipeline networks. Summary of the Utility Model

[0007] Preferably, the main rod is a round rod, and grooves evenly distributed in a circle are provided on the main rod, and the upper ends of the connecting rods are arranged in the grooves.

[0008] Preferably, a sliding rod is provided at the center of the main rod. The sliding rod is slidably installed within the main rod.

[0015] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] As Figures 1 to 4 shown, a municipal pipeline cleaning device includes a cleaning vehicle, which is composed of a chassis 1, walking legs 2, a hydraulic rod 4, a main rod 5, and side rods 6. Four walking legs 2 are provided on the lower side of the chassis 1. Walking wheels 3 are provided at the lower part of the walking legs 2 to facilitate the movement of the device; the rear section of the hydraulic rod 4 is fixed in the middle of the chassis 1, the front section of the hydraulic rod 4 is connected to the main rod 5, and a plurality of side rods 6 evenly distributed in a circle are hinged at the lower end of the main rod 5; a connecting rod 7 is hinged in the middle of each side rod 6, and the upper end of the connecting rod 7 is hinged under the lower side of the lock ring 8.

[0017] The middle part of the locking ring 8 is provided with symmetrical through ports 9. On the outer wall of the lower part of the main rod 5, there is a spring lock block 10. The upper side of the spring lock block 10 is an arc surface, and its lower side is a straight surface perpendicular to the main rod 5. When the spring lock block 10 is pressed, it will retract into the main rod 5. The spring lock block 10 and the through port 9 are vertically aligned. The pressed spring lock block 10 will pass through the through port 9. The width of the through port 9 is smaller than the length of the spring lock block 10 extending out of the main rod 5, thus realizing the locking function.

[0018] As the main rod 5 moves downward, when the main rod 5 touches the bottom, the hydraulic rod 4 slowly moves downward, and the side rod 6 will stretch and open around. As the side rod 6 opens, the connecting rod 7 will drive the locking ring 8 to move downward. When the locking ring 8 moves to the bottom of the main rod 5, the through port 9 on the locking ring 8 will pass through the spring lock block 10. After the spring lock block 10 passes through the through port 9, it will reset and pop out, and it will block the upward movement of the locking ring 8, that is, when the side rod 6 expands and moves upward, it will not gather and retract again.

[0019] The main rod 5 is a round rod, and the main rod 5 is provided with grooves 11 evenly distributed in a circumferential manner. The upper end of the connecting rod 7 is arranged in the groove 11. When adopting this structure, the side rod 6 located at the lower end of the main rod 5 can penetrate into the pipeline 15 at the smallest inclination angle.

[0020] A sliding rod 12 is arranged in the center of the main rod 5. The sliding rod 12 is slidably installed in the main rod 5. The lower end of the sliding rod 12 is provided with a trapezoidal cylinder 13. The diameter of the upper base of the trapezoidal cylinder 13 is smaller than the shortest distance from the side rod 6 to the center of the upper base, and the diameter of the lower base of the trapezoidal cylinder 13 is not less than the diameter of the main rod 5.

[0021] The trapezoidal cylinder 13 is located below the side rod 6. The trapezoidal cylinder 13 touches the bottom first. As the main rod 5 continues to move downward, the trapezoidal cylinder 13 will gradually push the side rod 6 outward, facilitating the outward expansion of the side rod 6.

[0022] The side rod 6 can be set as an L-shaped rod, its lower end is a short cross bar 14, and a fillet is provided at its connection to facilitate the outward opening of the side rod 6.

[0023] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
