Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipeline dredging, and particularly relates to a pipeline dredging device used for urban pipeline drainage. Background Art

[0002] Drainage pipes refer to the system composed of pipes and ancillary facilities that collect and discharge sewage, wastewater and rainwater. With the continuous acceleration of urbanization, more and more urban drainage pipes have excessive debris accumulation and siltation due to untimely daily maintenance, disrepair or inadequate cleaning of the pipes, resulting in pipe blockage and affecting drainage. In addition, since drainage pipes are used to collect and discharge sewage, wastewater and rainwater, especially when discharging domestic sewage, the dirt in the sewage is easy to accumulate on the inner wall of the pipe, narrowing the inner diameter of the pipe and affecting the normal drainage of the pipe.

[0003] After searching, a Chinese patent with publication number CN215166434U discloses a pipe dredging device for urban pipe drainage, including a frame plate, a screw rod is connected to the inner thread of the frame plate, a connecting rod is fixedly connected to the bottom end of the screw rod, a dredging plate is fixedly connected to the bottom of the connecting rod, a plurality of top columns are fixedly connected to the bottom of the dredging plate, two wall-attached cleaning plates are provided on the outside of the connecting rod, the two wall-attached cleaning plates are symmetrically distributed, and telescopic columns are fixedly connected to the inner end faces of the two wall-attached cleaning plates.

[0004] When the equipment in the above-mentioned public documents is used to dredge the pipeline, it is mainly hand-held and focused on the pipeline mouth. The dredging depth is limited, and it is impossible to dredge and descale deeper in the pipeline. The dirt attached to the inner wall of the pipeline is not just in one place, but the entire inner wall is covered with dirt. If only the pipe mouth is dredged and descaled, there is still a risk of blockage in other places in the pipeline. Utility Model Content

[0021] refer to Figures 1 to 3 The pipe dredging device for urban pipe drainage described in this embodiment includes an annular mounting seat 1, a plurality of moving mechanisms 2 are provided at equal angles on the outer surface of the annular mounting seat 1, a T-shaped seat 3 is fixedly installed on the inner surface of the annular mounting seat 1, a controller 4 is fixedly installed at the lower end of the T-shaped seat 3, a driving mechanism 5 is provided at the upper end of the T-shaped seat 3, and a scraping mechanism 6 is provided on the outer side of the driving mechanism 5;

[0022] The moving mechanism 2 includes an electric push rod 201, which is fixedly mounted at an equal angle on the outer surface of the annular mounting seat 1. The output end of the electric push rod 201 is fixedly mounted with a U-shaped seat 202, and the inner side of the U-shaped seat 202 is rotatably connected with a moving wheel 203. The outer side of the U-shaped seat 202 is fixedly mounted with a servo motor 204, and the output shaft of the servo motor 204 extends into the inner side of the U-shaped seat 202 and is fixedly mounted on one end of the wheel axle of the moving wheel 203. The driving mechanism 5 includes a reduction motor 501, which is fixedly mounted on the upper end of the T-shaped seat 3. The output end of 501 is fixedly installed with a driving rod 502 through a coupling, and the driving rod 502 is movably connected to the upper end of the T-shaped seat 3 through a bearing seat. The reduction motor 501 is fixedly connected to the controller 4 through a wire, and the end of the driving rod 502 away from the reduction motor 501 is fixedly installed with the scraping mechanism 6. In order to enable the scraping mechanism 6 to dredge and remove scale in deeper parts of the pipeline, a circular array distribution of moving mechanisms 2 is installed on the periphery of the annular mounting seat 1. The electric push rod 201 in the moving mechanism 2 can also adjust the distance between the moving wheel 203 and the annular mounting seat while serving as a bracket. 1, so that when the center of the annular mounting seat 1 coincides with the center of the pipe, the moving wheels 203 in the several moving mechanisms 2 can all be against the inner wall of the pipe, and the servo motor 204 drives the moving wheels 203 to rotate to realize the function of moving the device in the pipe. The device moves to the depth of the pipe while being cleared and descaled by the scraping mechanism 6, and the clearing and descaling effect is better; the multiple moving mechanisms 2 are distributed in a circular array with the central axis of the annular mounting seat 1, and the electric push rod 201 and the servo motor 204 are respectively electrically connected to the controller 4, and the electric push rod 201 is in motion The position of the moving wheel 203 from the annular mounting seat 1 can be adjusted while serving as a bracket, so that when the center of the annular mounting seat 1 coincides with the center of the pipe, the moving wheels 203 in the several moving mechanisms 2 can all be pressed against the inner wall of the pipe to adapt to pipes with different inner diameters. The servo motor 204 drives the moving wheel 203 to rotate to realize the function of moving the device in the pipe. The controller 4 controls the electric push rod 201 and the servo motor 204. The controller 4 can be connected to an external power line or a control line, so that only the wire needs to be extended to follow the device into the pipe.

[0023] The scraping mechanism 6 includes an annular plate 603, a connecting block 601 and a connecting rod 602. The center of the connecting block 601 is fixedly installed with the end of the driving rod 502 away from the reduction motor 501. The connecting rod 602 is fixedly connected at an equal angle between the inner surface of the annular plate 603 and the connecting block 601. A knife holder 604 is fixedly installed at an equal angle on the outer surface of the annular plate 603. A scraper 605 is fixedly installed at one end of the knife holder 604 away from the annular plate 603. When the scraping mechanism 6 is driven to rotate by the driving mechanism 5, the scraper 605 surrounding the annular plate 603 is mainly used to dredge the dirt on the inner wall of the pipeline. The scraper 605 can be removed and replaced. If the inner diameter of the pipeline is large, a longer and more suitable scraper 605 is installed. Otherwise, a shorter and more suitable scraper 605 is installed. 5. Adaptation means that after the scraper 605 is installed, when the center of the annular plate 603 coincides with the center of the pipe, the end of each scraper 605 just contacts the inner wall of the pipe. In addition to being replaceable, the scraper 605 is also installed on the annular plate 603 with the blade holder 604 tilted, similar to a propeller structure, so that when the scraper 605 scrapes off the dirt, it can be pushed aside by the scraper 605 instead of being constantly pushed by the adjacent scraper 605; the scraped dirt and impurities fall to the bottom of the pipe and will not interfere with the moving device. In addition to being replaceable, the scraper 605 is also installed on the annular plate 603 with the blade holder 604 tilted, similar to a propeller structure, so that when the scraper 605 scrapes off the dirt, it can be pushed aside by the scraper 605 instead of being constantly pushed by the adjacent scraper 605.

[0024] refer to Figure 3 There are six scrapers 605 at equal angles. One end of the scraper 605 is fixedly installed on the inner side of the knife holder 604 by a screw and a nut. After the scraper 605 is inserted into the knife holder 604, a screw is used to penetrate the scraper 605 and the knife holder 604 from one side of the knife holder 604, and then the screw is used to lock the thread with a nut, so that the scraper 605 can be easily disassembled.

[0025] refer to Figure 2 Three moving mechanisms 2 are arranged at equal angles on the outer side of the annular mounting seat 1. The electric push rod 201 is fixedly connected to the controller 4 through a wire, and the controller 4 can electrically control the electric push rod 201 through the line.

[0026] refer to Figure 2 A plurality of anti-skid grooves 7 are provided on the outer surface of the wheel body of the moving wheel 203, and the anti-skid grooves 7 of the moving wheel 203 are distributed in an inclined shape. The anti-skid grooves 7 on the outer surface of the moving wheel 203 can not only enable the anti-skid grooves 7 on the moving wheel 203 to push the device as a whole to move inside the pipeline by relying on the friction with the inner wall of the pipeline when rotating, but also prevent the driving mechanism 5 from driving the scraping mechanism 6 to rotate and drive the annular mounting seat 1 to move inside the pipeline. The anti-skid grooves 7 on the moving wheel 203 can prevent it from sliding laterally inside the pipeline.

[0027] Principle and advantages of use: Before clearing the pipeline, first adjust the length of the electric push rod 201 according to the inner diameter of the pipeline, so that the moving wheel 203 at the end of the electric push rod 201 can just press against the inner wall of the pipeline. At the same time, it is also necessary to replace and install the annular plate 603 of appropriate size in advance, so that the scraper 605 can just scrape the inner wall of the pipeline when the scraping device is driven to rotate by the driving device;

[0028] After the preparation work is done, the device is placed in the pipeline, and then the reduction motor 501 is started. The output shaft of the reduction motor 501 drives the driving rod 502 to rotate through the coupling, and then the driving rod 502 drives the entire scraping device to rotate. When the scraping device rotates, the scraper 605 installed obliquely can scrape off the impurities and dirt on the inner wall of the pipeline;

[0029] As the descaling work proceeds, the controller 4 can also simultaneously drive the three servo motors 204 to start driving the moving wheel 203. When the moving wheel 203 rotates, it can stick to the inner wall of the pipe so that the entire device moves into the pipe, which can clear deeper and longer drainage pipes.
