Description

Technical Field

[0001] This application relates to the technical field of drainage pipeline dredging, and in particular to a municipal road drainage dredging device. Background Art

[0002] At present, the drainage system of municipal roads is an important part of urban infrastructure. Its main function is to collect and discharge rainwater and domestic sewage to ensure the normal operation of the city. Whether the drainage system is unobstructed directly affects the city's flood control and drainage capacity as well as environmental hygiene. Therefore, it is very necessary to regularly dredge the drainage system.

[0003] In related technologies, a high-pressure cleaning vehicle is usually used to dredge municipal drainage pipelines. The specific dredging method is to first insert a high-pressure water gun downward from the drainage pipeline opening into the drainage pipeline, and use the high-pressure water gun to loosen or directly remove the sediment. Then, a vacuum pump is used to suck out the sludge and other sundries from the drainage pipeline.

[0004] Regarding the above dredging method, although the high-pressure water gun can smoothly disperse the sludge at the bottom of the drainage pipeline, due to the limitation of the scouring angle of the high-pressure water gun, for the sludge on the inner wall of the drainage pipeline, the cleaning effect of the high-pressure water gun is not good, and the sludge is easy to accumulate continuously on the inner wall of the drainage pipeline, resulting in an unsatisfactory dredging effect. Utility Model Content

[0005] This application provides a municipal road drainage dredging device, which can effectively remove the sludge on the inner wall of the drainage pipeline, thereby further improving the dredging effect of the drainage pipeline.

[0006] The municipal road drainage dredging device provided by this application adopts the following technical solutions:

[0007] A municipal road drainage dredging device includes a dredging pipe. A dredging drill bit is coaxially arranged at the bottom of the dredging pipe. A water inlet pipe is connected to the top of the dredging pipe. A plurality of scouring holes communicating with the water inlet pipe are penetrated through the dredging drill bit. A turntable is coaxially sleeved on the outer side wall of the dredging pipe, and the turntable is rotatably arranged outside the dredging pipe. A driven gear is coaxially arranged on the turntable, and the driven gear is rotatably sleeved on the dredging pipe. A driving motor is also arranged on the dredging pipe. A driving gear is arranged on the output shaft of the driving motor, and the driving gear meshes with the driven gear. Cleaning brushes are circumferentially and sequentially arranged at intervals on the turntable, and the cleaning brushes are used to wash the inner side wall of the drainage pipeline.

The return spring expands and contracts along the sliding direction of the corresponding telescopic rod. One end of the return spring abuts against the inner side wall of the turntable, and the other end of the return spring abuts against the telescopic rod; the return spring is used to push the telescopic rod away from the turntable.

[0009] Preferably, a locking member located outside the turntable is sleeved on the telescopic rod. The locking member is rotatably arranged on the telescopic rod. A locking tube facing the locking member is arranged on the turntable. External threads are arranged on the outer side wall of the locking tube, and the locking member is used for threaded connection with the corresponding locking tube.

[0010] Preferably, a plurality of spray pipes are communicated with the dredging pipe. The spray pipes are located between the turntable and the dredging bit, and the spray ports of the spray pipes extend towards the cleaning brush.

[0011] Preferably, it further includes a support frame, and the water inlet pipe is movably penetrated through the support frame; the diameter of the support frame is larger than the diameter of the drainage pipe opening, and the support frame is used for being erected outside the drainage pipe opening.

[0015] Insert the turntable into the drainage pipe to ensure that the cleaning brush is pressed against the inner side wall of the drainage pipe under the action of the return spring and the telescopic rod; then drive the turntable to rotate through the driving motor. As the turntable rotates, the cleaning brush can wash the silt on the inner side wall of the drainage pipe; during the washing process, the sprayed water from the spray pipe can wash the inner side wall of the drainage pipe, thereby further improving the cleaning effect on the inner wall of the drainage pipe;

[0016] The dredging bit can ensure the dredging effect on the silt at the bottom of the drainage pipe.

Specific implementation manners

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] An embodiment of the present application discloses a municipal road drainage and silt cleaning device.

[0022] Referring to Figure 1 and Figure 2 , the municipal road drainage and silt cleaning device includes a silt cleaning pipe 1 with a hollow interior. At the bottom of the silt cleaning pipe 1, a silt cleaning drill bit 2 for removing the silt at the bottom of the drainage pipe is coaxially and fixedly installed. The top of the silt cleaning pipe 1 is communicated with a water inlet pipe 3, and the water inlet pipe 3 is used for injecting high-pressure water flow into the silt cleaning pipe 1. A plurality of flushing holes 20 communicating with the water inlet pipe 3 are penetrated through the silt cleaning drill bit 2. During operation, the high-pressure water flow ejected from the flushing holes 20 can flush and break the silt.

[0023] As shown in Figure 1 and Figure 2 , a turntable 4 is coaxially sleeved on the outer side wall of the silt cleaning pipe 1, and the turntable 4 is rotatably arranged outside the silt cleaning pipe 1. A driven gear 40 is coaxially and fixedly installed on the turntable 4, and the driven gear 40 is rotatably sleeved outside the silt cleaning pipe 1. A driving motor 5 is also fixedly installed on the silt cleaning pipe 1, and a driving gear 50 is coaxially installed on the output shaft of the driving motor 5. The driving gear 50 meshes with the driven gear 40. The driving motor 5 drives the turntable 4 to rotate through the mutual cooperation of the driving gear 50 and the driven gear 40.

[0024] As shown in Figure 1 and Figure 2 , a plurality of telescopic rods 42 are movably arranged on the circumferential outer side wall of the turntable 4, and the telescopic rods 42 are evenly spaced in the circumferential direction in sequence. One end of the telescopic rod 42 is limited in the turntable 4, and the telescopic rod 42 is slidably arranged on the turntable 4 along the radial direction of the turntable 4. The other end of the telescopic rod 42 extends out of the turntable 4 to the outside of the turntable 4, and a cleaning brush 41 is fixedly installed at the end of the telescopic rod 42 extending out of the turntable 4. The cleaning brushes 41 correspond to the telescopic rods 42 one by one, and the cleaning brushes 41 are used for washing the inner side wall of the drainage pipe.

[0025] As shown in Figure 1 andFigure 2 As shown, a return spring 43 corresponding to the telescopic rod 42 one by one is further arranged in the turntable 4, and the return spring 43 expands and contracts along the sliding direction of the respective opposite telescopic rod 42. One end of the return spring 43 abuts against the inner side wall of the turntable 4, and the other end of the return spring 43 abuts against the respective opposite telescopic rod 42. In the natural state, the return spring 43 is used to push the respective opposite telescopic rod 42 away from the turntable 4, so as to ensure that the cleaning brush 41 abuts against the inner side wall of the drainage pipe.

[0026] As Figure 1 、 Figure 2 shown, a locking member 44 located outside the turntable 4 is sleeved on the telescopic rod 42. The locking member 44 is rotatably arranged on the telescopic rod 42, and the locking member 44 is limited at a designated position on the telescopic rod 42. A locking tube 45 facing the respective locking member 44 is fixedly installed on the turntable 4. An external thread is arranged on the outer side wall of the locking tube 45, and the locking member 44 is used for threadedly connecting with the respective opposite locking tube 45. When it is necessary to store the telescopic rod 42, by pulling the locking member 44 towards the direction close to the respective locking tube 45, at this time, the telescopic rod 42 will gradually move into the turntable 4 under the traction of the locking member 44. Finally, by threadedly connecting the locking member 44 to the outside of the locking tube 45, the position of the telescopic rod 42 can be locked at this time, which facilitates the storage of the telescopic rod 42.

[0027] As Figure 1 、 Figure 2 shown, a plurality of spray pipes 11 are communicated with the dredging pipe 1. The spray pipes 11 are located between the turntable 4 and the dredging bit 2, and the spray openings of the spray pipes 11 extend towards the direction close to the cleaning brush 41. During the washing process, the spray water sprayed from the spray pipes 11 can wash the inner side wall of the drainage pipe, so as to further improve the cleaning effect on the inner wall of the drainage pipe.

[0028] As Figure 1 、 Figure 2 shown, it further includes a support frame 6. The water inlet pipe 3 is movably penetrated through the support frame 6. The diameter of the support frame 6 is larger than the diameter of the drainage pipe opening. The support frame 6 is used for being erected outside the drainage pipe opening, so as to prevent the cleaning personnel from accidentally falling into the drainage pipe. Two operating rods 10 are fixedly installed on the top of the dredging pipe 1. The operating rods 10 are movably penetrated through the support frame 6. The cleaning personnel can drive the dredging pipe 1 to lift and lower in the drainage pipe through the operating rods 10.

[0029] As Figure 1 、 Figure 2 shown, a plurality of adjusting seats 7 are circumferentially and spacedly arranged on the support frame 6. The adjusting seats 7 are vertically arranged, and the adjusting seats 7 are threadedly connected to the support frame 6. A rubber pad is fixedly arranged at the bottom of the adjusting seat 7. The rubber pad can increase the friction between the bottom of the adjusting seat 7 and the ground, so as to ensure the stability of the support frame 6.

[0030] The implementation principle is as follows: Insert the turntable 4 into the drainage pipe to ensure that the cleaning brush 41 is pressed against the inner wall of the drainage pipe under the action of the return spring 43 and the telescopic rod 42. Subsequently, drive the turntable 4 to rotate through the drive motor 5. As the turntable 4 rotates, the cleaning brush 41 can wash the sludge on the inner wall of the drainage pipe. During the washing process, the sprayed water from the spray pipe 11 can flush the inner wall of the drainage pipe, thereby further improving the cleaning effect on the inner wall of the drainage pipe. The dredging drill bit 2 can ensure the dredging effect on the sludge at the bottom of the drainage pipe. The high-pressure water flow ejected from the scouring holes 20 during the downward drilling process of the dredging drill bit 2 can effectively loosen and break the sediment, ensuring the dredging effect.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
