Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipeline dredging, in particular to a dredging device for building drainage engineering. Background Art

[0002] When the water supply and drainage pipes in a construction project are blocked, a dredging structure is usually used to dredge the pipes. The dredging structure can also be called a pipe dredging machine. The pipe dredging machine is a pipe dredging equipment in the dredging structure. However, the noise reduction effect of the existing dredging structure needs to be improved. After the dredging structure is started, a relatively harsh sound will be emitted. The harsh sound will have a certain impact on the user when the user uses the dredging structure, which is not conducive to the user to dredge the water supply and drainage pipes, and reduces the comfort of the dredging structure when used.

[0003] Application No.: CN202221804028.7 "A water supply and drainage dredging structure for construction projects" is used. When the user starts the pipe dredging machine, the noise reduction sleeve can effectively absorb the noise of the pipe dredging machine when it is working, so as to reduce the noise decibel. The silencer sleeve, the sound-absorbing cotton sleeve and the sound-absorbing sleeve can further absorb the noise absorbed by the noise reduction sleeve in turn, so that the noise decibel continues to decrease. The heat-absorbing inner shell can absorb the temperature of the pipe dredging machine when it is working, so as to reduce the working temperature of the pipe dredging machine. The heat-conducting pipe and the heat-conducting frame can conduct the temperature of the heat-absorbing inner shell, so that the temperature is conducted to the inside of the heat dissipation outer shell for cooling. After the noise enters the heat-conducting pipe, it will be absorbed by the resonance rod and the vibration-conducting rod, and the resonance rod and the vibration-conducting rod will vibrate, which will offset the noise emitted by the pipe dredging machine, so as to further reduce the noise. The sound insulation sleeve and the sound insulation sheet can isolate the noise emitted by the pipe dredging machine, so that the noise is not easily transmitted to the outside, thereby achieving the advantage of good noise reduction effect.

[0004] However, the above-mentioned water supply and drainage dredging structure cannot be used for dredging pipes of different diameters, and its application range is not wide enough, making the dredging structure inconvenient to use. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a dredging device for building drainage engineering, including: a telescopic rotating rod 2 with adjustable length, a stirring assembly 3 suitable for pipes with different diameters is provided on the side of the telescopic rotating rod 2, and a transmission assembly 1 for driving the telescopic rotating rod 2 to rotate is provided on the top of the telescopic rotating rod 2.

[0026] The stirring assembly 3 includes: a first fixing plate 31, one side of the first fixing plate 31 is rotatably connected to one end of the first stirring rod 32, the other end of the first stirring rod 32 is rotatably connected to one end of the second stirring rod 33, the other end of the second stirring rod 33 is rotatably connected to one side of the second fixing plate 34, the outside of the second fixing plate 34 is fixedly connected to the side of the sliding sleeve 35, a limiting block 38 is provided inside the inner ring of the sliding sleeve 35, and the limiting block 38 and the sliding sleeve 35 are integrally formed. A threaded through hole 37 is provided on the side of the sliding sleeve 35, and the hole wall of the threaded through hole 37 is threadedly connected to the outside of the locking screw 36.

[0027] Further, first loosen the locking screw 36 so that the sliding sleeve 35 can slide outside the sliding rod 22. When the sliding sleeve 35 is pushed towards the cylinder body 21, the sliding sleeve 35 pushes the second stirring rod 33 through the second fixing plate 34, so that the second stirring rod 33 pushes one end of the first stirring rod 32, and further makes the rotating connection part of the first stirring rod 32 and the second stirring rod 33 expand outwards, so as to make the rotating connection part of the first stirring rod 32 and the second stirring rod 33 able to adhere to the inner wall of the pipe. When the sliding sleeve 35 is pushed away from the cylinder body 21, the sliding sleeve 35 pulls the second stirring rod 33 through the second fixing plate 34, so that the second stirring rod 33 pulls one end of the first stirring rod 32, and further makes the rotating connection part of the first stirring rod 32 and the second stirring rod 33 close to the sliding rod 22. After the stirring assembly 3 is adjusted, tighten the locking screw 36 so that one end of the locking screw 36 abuts against the side of the sliding rod 22, so that the sliding sleeve 35 can no longer slide outside the sliding rod 22; through the above method, the outer diameter of the dredging device can be adjusted according to the pipe diameter of the pipe, so that the dredging device is suitable for dredging pipes with different pipe diameters, improving the scope of application and making the dredging device more convenient to use.

[0028] The telescopic rotating rod 2 includes: a sliding rod 22, the side of the sliding rod 22 is slidably inserted into the inner ring of the sliding sleeve 35, and the side of the sliding rod 22 is also fixedly connected to the outside of the first fixing plate 31. The bottom end of the sliding rod 22 is fixedly connected to the top of the limiting plate 23, and a limiting chute 24 is formed on the side of the sliding rod 22, and the slot wall of the limiting chute 24 is slidably connected to the outside of the limiting block 38. The side of the sliding rod 22 is slidably inserted into the inner wall of the cylinder 21, and a strip-shaped through hole 25 is formed on the side of the cylinder 21. A plurality of groups of arc-shaped clamping grooves 26 are equidistantly formed on the hole walls on both sides of the strip-shaped through hole 25, and the slot wall of the arc-shaped clamping groove 26 is slidably connected to the side of the positioning screw 27, and one end of the positioning screw 27 is threadedly connected to the side of the top end of the sliding rod 22.

[0029] Further, pull out the sliding rod 2 from the cylinder 21 to change the overall length of the telescopic rotating rod 2. After the length is adjusted, turn the positioning screw 27 so that the positioning screw 27 moves towards the sliding rod 2 until the side of the positioning screw 27 is stuck in the arc-shaped clamping groove 26. In this way, the positioning screw 27 cannot move, and further the sliding rod 2 cannot slide in the cylinder 21, and the overall length of the telescopic rotating rod 2 is fixed.

[0030] The transmission component 1 includes: a mounting block 13, a circular through hole 12 for the output shaft of the motor 11 to pass through is formed on the top of the mounting block 13, and the outside of the motor 11 is fixedly connected to the top of the mounting block 13. The output shaft of the motor 11 is fixedly connected to the top end of the cylinder 21, and one side of the mounting block 13 is fixedly connected to one end of the handle 14.

[0031] Further, after the adjustment is completed, hold the handle 14 by hand, insert the stirring component 3 and the telescopic rotating rod 2 into the pipeline, and then start the motor 11. The motor 11 drives the telescopic rotating rod 2 and the stirring component 3 to rotate, so that the first stirring rod 32 and the second stirring rod 33 stir and dredge the blockage. The cooperation of the limiting chute 24 and the limiting block 38 prevents the sliding sleeve 35 and the sliding rod 22 from rotating relative to each other.

[0032] Working principle: When in use, expand or contract the stirring assembly 3 according to the large inner diameter of the pipeline. First, loosen the locking screw 36 so that the sliding sleeve 35 can slide outside the sliding rod 22. When pushing the sliding sleeve 35 towards the cylinder body 21, the sliding sleeve 35 pushes the second stirring rod 33 through the second fixing plate 34, so that the second stirring rod 33 pushes one end of the first stirring rod 32, and then the rotating connection between the first stirring rod 32 and the second stirring rod 33 expands outwards, so as to make the rotating connection between the first stirring rod 32 and the second stirring rod 33 able to adhere to the inner wall of the pipeline. When pushing the sliding sleeve 35 in the direction away from the cylinder body 21, the sliding sleeve 35 pulls the second stirring rod 33 through the second fixing plate 34, so that the second stirring rod 33 pulls one end of the first stirring rod 32, and then the rotating connection between the first stirring rod 32 and the second stirring rod 33 moves closer to the sliding rod 22. After the stirring assembly 3 is adjusted, tighten the locking screw 36 so that one end of the locking screw 36 abuts against the side of the sliding rod 22, so that the sliding sleeve 35 can no longer slide outside the sliding rod 22; in the above way, the outer diameter of the dredging device can be adjusted according to the diameter of the pipeline, so that the dredging device is suitable for dredging pipelines with different diameters, improving the scope of application and making the dredging device more convenient to use.

[0033] When the blockage position is deep in the pipeline, the sliding rod 22 can be pulled out of the cylinder body 21 to change the overall length of the telescopic rotating rod 2. After the length is adjusted, turn the positioning screw 27 so that the positioning screw 27 moves towards the sliding rod 22 until the side of the positioning screw 27 is stuck in the arc-shaped card slot 26, so that the positioning screw 27 cannot move, and then the sliding rod 22 cannot slide in the cylinder body 21, and the overall length of the telescopic rotating rod 2 is fixed.

[0034] After the adjustment is completed, hold the handle 14 and insert the stirring assembly 3 and the telescopic rotating rod 2 into the pipeline, and then start the motor 11. The motor 11 drives the telescopic rotating rod 2 and the stirring assembly 3 to rotate, so that the first stirring rod 32 and the second stirring rod 33 stir and dredge the blockage.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
