Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically a rainwater and sewage pipeline dredging and cleaning device. Background Technology

[0002] With the continuous acceleration of urbanization, the impermeable area is gradually increasing, which leads to an increase in the instantaneous rainwater flow in some cities during the rainy season. In order to meet the needs of people's daily life, a large number of pipes are built underground. During the use of pipes, garbage and fallen leaves are washed into the pipes by rainwater, which often causes blockages. If they are not dealt with in time, they will cause safety hazards.

[0003] According to Chinese patent document CN213014636U, a municipal stormwater and sewage pipe cleaning device is disclosed, including an installation block with an installation cavity. A rotating hole is formed on the lower surface of the installation block, and a rotating rod passes through the installation block, rotatably connected to the rotating hole. The top end of the rotating rod is rotatably connected to the top wall of the installation cavity. A first limiting ring and a second limiting ring are provided on the side of the rotating rod. The second limiting ring is sleeved on the side of the rotating rod and rotatably connected to it. The device also includes a cleaning cylinder disposed between the first and second limiting rings, sleeved on the rotating rod and slidably connected to it. A fixing sleeve is provided at the bottom end of the rotating rod, and a fixing component is provided on the fixing sleeve. The fixing component secures the fixing sleeve against the second limiting ring, fixing the cleaning cylinder between the first and second limiting rings. A driving component for rotating the rotating rod is provided within the installation cavity. This application facilitates the cleaning of municipal pipes of different diameters.

[0004] While the aforementioned devices can clean pipes of different diameters, different diameter cleaning cylinders are required for different pipes, making the operation rather cumbersome. Therefore, a new device for dredging and cleaning rainwater and sewage pipes is proposed. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a rainwater and sewage pipe dredging and cleaning device includes a handle 1. A connecting block 2 is fixedly installed on the upper end of the handle 1. A connecting shaft 4 is rotatably connected to the upper end of the connecting block 2. A rotating rod 3 is fixedly connected to the upper end of the connecting shaft 4. Three cleaning components are arranged on the outer wall of the rotating rod 3 in a circular array. Each cleaning component consists of a scraper 6, a movable rod 7, a sleeve 8, a driven helical gear 14, a connecting rod 15, and an adjusting screw 16. Two movable rods 7 are fixedly connected to the side wall of the scraper 6. The outer surface of the two movable rods 7... Sleeves 8 are slidably fitted on both sides. Two sleeves 8 are fixedly connected to the outer wall of the rotating rod 3. An adjusting screw 16 is provided inside one of the sleeves 8. One end of the adjusting screw 16 is threaded into the inside of the movable rod 7. The other end of the adjusting screw 16 is rotatably connected to the inner wall of the sleeve 8 and extends into the movable groove 10 opened inside the rotating rod 3. A connecting rod 15 is fixedly connected to the extended end of the adjusting screw 16. A driven helical gear 14 is fixedly connected to the end of the connecting rod 15. A drive mechanism acting on the driven helical gear 14 is provided inside the movable groove 10.

[0022] The connecting block 2 is equipped with a drive motor 17, and the output shaft of the drive motor 17 is fixedly connected to the end of the connecting shaft 4.

[0023] The drive motor 17 can drive the connecting shaft 4 to rotate, thereby driving the rotating rod 3 and the scraper 6 to rotate.

[0024] The drive mechanism consists of a rotating shaft 11, an adjusting component 12, and a driving helical gear 13. The upper and lower ends of the rotating shaft 11 are rotatably connected to the upper and lower inner walls of the movable groove 10, respectively. The driving helical gear 13 is fixedly sleeved on the outer wall of the rotating shaft 11. The driving helical gear 13 meshes with three driven helical gears 14, respectively. The upper end of the rotating shaft 11 extends to the upper end of the rotating rod 3 and is fixedly connected to the adjusting component 12.

[0025] In use, rotating the adjusting component 12 drives the rotating shaft 11 to rotate, which in turn drives the driving helical gear 13 to rotate, which in turn drives the three driven helical gears 14 to rotate. The rotation of the three driven helical gears 14 will drive the connecting rod 15 and the adjusting screw 16 to rotate synchronously, which in turn drives the movable rod 7 to slide inside the sleeve 8. By controlling the length of the movable rod 7 extending out of the sleeve 8, the distance between the scraper 6 and the rotating rod 3 can be controlled, so that the device can be used for cleaning pipes of different diameters.

[0026] The adjusting member 12 has multiple anti-slip seams on its outer wall, and the multiple anti-slip seams are arranged in a ring array.

[0027] The anti-slip seams can increase the distance between the user's hand and the adjustment component 12.

[0028] Among them, three fixing plates 9 are fixedly connected to the upper side wall of the rotating rod 3. The three fixing plates 9 are arranged in a ring array, and the upper ends of the three fixing plates 9 are fixedly connected to the breaking drill bit 5.

[0029] The set-in crushing drill bit 5 can easily crush obstacles inside the pipe. The crushing drill bit 5 is equipped with blades, which are not shown in the figure. The gap between the two adjacent fixed plates 9 allows the worker to easily pass his hand through to rotate the adjusting component 12.

[0030] This utility model provides a device for dredging and cleaning rainwater and sewage pipes, the specific working principle of which is as follows:

[0031] In use, hold the handle 1 and insert the device into the pipe to be cleaned. Start the drive motor 17 to drive the connecting shaft 4 to rotate, which in turn drives the rotating rod 3 and the scraper 6 to rotate. The scraper 6 can scrape off the dirt on the inner wall of the pipe. When cleaning pipes of different diameters, rotate the adjusting component 12 to drive the rotating shaft 11 to rotate, which in turn drives the driving helical gear 13 to rotate, which in turn drives the three driven helical gears 14 to rotate. The rotation of the three driven helical gears 14 will drive the connecting rod 15 and the adjusting screw 16 to rotate synchronously, which in turn drives the movable rod 7 to slide in the sleeve 8. By controlling the length of the movable rod 7 extending out of the sleeve 8, the distance between the scraper 6 and the rotating rod 3 can be controlled, so that the device can be used to clean pipes of different diameters. The crushing drill bit 5 at the front end of the device can easily crush obstacles inside the pipe. The crushing drill bit 5 is equipped with blades, which are not shown in the figure.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
