Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, specifically to a high-efficiency dredging device for municipal drainage pipelines. Background Technology

[0002] Over time, silt and debris accumulate inside pipes. For example, during the rainy season, if pipes become blocked, rainwater cannot drain properly, leading to flooding on city roads. In low-lying areas, poor drainage can easily cause water depths of tens of centimeters, severely impacting traffic and pedestrian safety. Silt buildup reduces the pipe's cross-sectional area. Pipes with larger diameters may have their drainage area significantly reduced due to a thick layer of silt, decreasing drainage efficiency. Some substances in the silt may be corrosive, eroding the pipe's inner walls. Furthermore, the accumulation of debris increases the pipe's load. When pipes are blocked by silt, sewage may overflow from manholes or other vulnerable areas, emitting an unpleasant odor and polluting surrounding soil, surface water, and groundwater. This can also negatively impact the health of nearby residents. Pipe dredging primarily utilizes pipe dredging equipment for cleaning.

[0003] For example, the prior art application number CN202220737311.6 provides a municipal pipeline dredging device, which relates to the field of pipeline dredging technology. It includes a fixed plate, a rotating rod rotatably connected to one side wall of the fixed plate, the rotating rod passing through one side wall of the fixed plate and extending to the other side of the fixed plate, a turntable fixedly installed at the end of the rotating rod away from the fixed plate, a sleeve sleeved on the outer surface of the end of the rotating rod away from the turntable, a spiral plate fixedly installed on the outer surface of the sleeve, and a drill bit installed at the end of the sleeve away from the rotating rod.

[0004] The aforementioned prior art, through practical use, primarily cleans the sludge inside the pipe by rotating a spiral plate. However, it has been found that due to the accumulation of compacted sludge on the inner wall of the pipe, simply using the rotation of the spiral plate to propel the sludge through the pipe is insufficient to completely remove the sludge adhering to the inner wall, resulting in poor cleaning performance. Therefore, based on actual usage, we propose improvements to the aforementioned prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a highly efficient dredging device for municipal drainage pipelines.

[0006] To achieve this technical objective, the present invention provides a high-efficiency dredging device for municipal drainage pipelines, comprising a servo motor and an auger. The output end of the servo motor is equipped with an auger, and an elastic element and an eccentric block are provided between the auger and the servo motor. The elastic element includes a first flange and a second flange, and a V-shaped spring is provided between the first flange and the second flange.

[0007] Preferably, the output end of the servo motor is fixed with a connecting shaft, and the outer surface of the connecting shaft is fixed with an eccentric block by bolts. One end of the connecting shaft is fixed to a flange.

[0008] Preferably, a plurality of the V-shaped springs are arranged in a ring around the axis of flange number one, with one side of the V-shaped springs riveted to the inner side of flange number one and the other side of the V-shaped springs riveted to the inner side of flange number two.

[0009] Preferably, a threaded rod is inserted between the first flange and the second flange, a rubber gasket is fitted around the threaded rod, and a nut is threaded around the threaded rod. The two sides of the rubber gasket are respectively pressed against the nut and the second flange.

[0010] Preferably, one side of the second flange is fixed with an extension shaft by bolts, and one end of the extension shaft is fixed to the auger by bolts.

[0011] Preferably, a base is fixed to the lower surface of the servo motor, a fixing member is provided at the lower end of the base, and a sliding groove is provided in the lower surface of the base.

[0012] Preferably, the fixing component includes a bidirectional screw and a threaded sleeve.

A support rod is integrally disposed on the lower surface of each threaded sleeve, and a triangular plate is integrally disposed on one side of the support rod. Beneficial effects

[0013] In this invention, when the servo motor is started to rotate the eccentric block, elastic component, and auger, the V-shaped spring in the elastic component will be repeatedly and slightly compressed and stretched by the No. 1 flange and No. 2 flange under the centrifugal force of the eccentric block, generating a certain vibration force. The vibration force will be transmitted to the rotating auger. After the vibrating auger is in the pipeline, the impact force generated by the vibration helps to break up and crush the sludge accumulated and adhered on the inner wall of the pipeline, which can improve the effect of pipeline dredging.

[0014] In addition, the internal structure of the sludge that was originally attached to the pipe wall or accumulated relatively tightly is destroyed by the vibration of the auger, its viscosity is reduced and its fluidity is enhanced. It is easier for the auger to stir it up, so that it can move more efficiently in the pipe, which can increase the speed at which the sludge is discharged from the pipe and thus increase the efficiency of dredging.

[0020] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0021] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] like Figures 1 to 4 As shown, this embodiment of the invention provides a high-efficiency dredging device for municipal drainage pipelines, including a servo motor 1 and an auger 2. The auger 2 is provided at the output end of the servo motor 1. An elastic element 4 and an eccentric block 5 are provided between the auger 2 and the servo motor 1. The elastic element 4 includes a first flange 41 and a second flange 42. 3-6 V-shaped spring pieces 43 are provided between the first flange 41 and the second flange 42. The V-shaped spring pieces 43 are made of metal copper or steel sheets with a thickness of 1-3cm.

[0023] refer to Figure 1 and Figure 3 The output end of the servo motor 1 is fixed with a connecting shaft 9, and the outer surface of the connecting shaft 9 is fixed with an eccentric block 5 by bolts. One end of the connecting shaft 9 is fixed to the first flange 41. Several V-shaped springs 43 are arranged in a ring around the axis of the first flange 41. One side of the V-shaped spring 43 is riveted to the inner side of the first flange 41, and the other side of the V-shaped spring 43 is riveted to the inner side of the second flange 42. A screw 44 is inserted between the first flange 41 and the second flange 42 to allow the first flange 41 and the second flange 42 to slide slightly to compress or stretch the V-shaped springs 43. A rubber pad 46 is sleeved around the screw 44, and a nut 45 is threaded around the screw 44. The two sides of the rubber pad 46 are respectively pressed against the nut 45 and the second flange 42. The rubber pad 46 is used to reduce the impact between the movement of the second flange 42 and the nut 45, and at the same time, it increases the elasticity of the V-shaped springs 43 through the second flange 42 to increase the vibration force.

[0024] refer to Figure 1 and Figure 2 One side of flange 42 is fixed with an extension shaft 3 by bolts. One end of the extension shaft 3 is fixed to the auger 2 by bolts. The extension shaft 3 can be disassembled to extend the position of the auger 2 in the pipeline and adapt to pipelines of different lengths.

[0025] refer to Figure 4 A base 7 is fixed to the lower surface of the servo motor 1. A fixing member 6 is provided at the lower end of the base 7. A sliding groove 8 is provided inside the lower surface of the base 7. The fixing member 6 includes a bidirectional screw 61 and a threaded sleeve 62. The bidirectional screw 61 is rotatably arranged between the front and rear walls of the sliding groove 8, and the threaded sleeve 62 is threaded on the outer periphery of the bidirectional screw 61. The threaded sleeve 62 is slidably installed inside the sliding groove 8. A clamping block 63 is fixed to the lower surface of the threaded sleeve 62 by bolts. The outer side of the clamping block 63 is arc-shaped to facilitate close contact with the inner wall of the circular sewage well, thereby increasing the stability of the device. A support rod 64 is integrally provided on the lower surface of each threaded sleeve 62, and a triangular plate 65 is integrally provided on one side of the support rod 64.

[0026] Working principle: First, the device is placed inside the sewage well. Then, by turning the bidirectional screw 61 in the fixing part 6, the two threaded sleeves 62 can be rotated to move inward or outward simultaneously. This causes the two threaded sleeves 62 to drive the two clamping blocks 63 to simultaneously press against the inner walls of sewage wells of different diameters, thereby increasing the adaptability to sewage wells. At the same time, when the clamping blocks 63 move, they will drive the triangular plate 65 to move, which can increase the support area of ​​the device and make the device more stable inside the sewage well.

[0027] Next, the servo motor 1 is started to drive the connecting shaft 9 to make the eccentric block 5, the elastic component 4 and the auger 2 rotate. The V-shaped spring piece 43 in the elastic component 4 will be repeatedly slightly compressed and stretched by the first flange 41 and the second flange 42 under the action of the centrifugal force of the eccentric block 5, generating a certain vibration force. The vibration force will be transmitted to the rotating auger 2 through the extension shaft 3. After the vibrating auger 2 is in the pipeline, the impact force generated by the vibration helps to break up the sludge accumulated and adhered on the inner wall of the pipeline, which can improve the effect of pipeline dredging.

[0028] In addition, the internal structure of the sludge that was originally attached to the pipe wall or accumulated relatively tightly is destroyed by the vibration, the viscosity is reduced and the fluidity is enhanced, making it easier for the sludge to be stirred by the auger. This allows it to move more efficiently in the pipe, increasing the speed at which the sludge is discharged from the pipe and thus increasing the efficiency of dredging.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
