[0002] Engineering construction refers to the construction, decoration, renovation and maintenance of various buildings, infrastructure and industrial projects during the construction process, which involves construction work related to dredging of lines or water pipes. In order to save manpower, corresponding pipe dredging devices are often used to increase the efficiency of pipe dredging.

[0003] The utility model with the existing authorization announcement number CN213409681U discloses a pipe dredger. The end of the elastic corrugated metal tube of the pipe dredger is quickly connected to a debris cleaning head, which is convenient for disassembly and assembly, storage, and flexible to operate. In addition, a plurality of debris cleaning claw assemblies are arranged on the end face of the debris cleaning head. The inclined claws are easier to entangle hair and other debris, making it convenient to remove the debris from the blocked part of the pipe, thereby improving the cleaning efficiency.

[0004] Although the cleaning head is easy to disassemble and replace, and the efficiency of debris cleaning is increased by the claw structure, the above technical solution, the drill bit and other related structures can only clear some pipeline debris, and lacks a cleaning structure that can fit the inner wall of the pipeline and clean the inner wall of the pipeline, resulting in a relatively general effect of pipeline cleaning and dredging.

[0005] Therefore, those skilled in the art provide a pipeline dredger for engineering construction to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0011] As a further solution of the utility model: the front side and the back side of the protective shell are both fixedly connected with a handle bar, and the outer surface of each handle bar is fixedly connected with an anti-slip sleeve.

[0012] As a further solution of the utility model: the inner wall of the protective shell is fixedly connected with a driving motor, the driving motor is electrically connected to the button controller through a wire, and the output end of the driving motor is fixedly connected with a rotating rod.

[0013] As a further solution of the utility model: the left end of the rotating rod is fixedly connected with a threaded sleeve, the inner wall of the threaded sleeve is threadedly connected to the outer surface of the elastic gooseneck tube, and the outer surface of the output end of the drive motor and the outer surface of the rotating rod are jointly fixedly connected with a coupling.

[0014] As a further solution of the utility model: an auxiliary bearing is fixedly connected to the inner wall of the protective shell, and the inner ring of the auxiliary bearing is fixedly connected to the outer surface of the rotating rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0025] The left end of the rotating cylinder 201 is fixedly connected with a spiral tower drill bit 202, and the interior of the rotating cylinder 201 is slidably connected with four sliding rods 203. The front and back sides of the protective shell 3 are fixedly connected with a grip rod 5, and the outer surface of each grip rod 5 is fixedly connected with an anti-slip sleeve 6. By providing the grip rod 5, it can be grasped and conveniently provide a driving force to the inner wall fitting cleaning mechanism 2. By providing the anti-slip sleeve 6, the friction force on the outer surface of the grip rod 5 can be increased, thereby increasing the comfort and stability when the hand holds the grip rod 5.

[0026] Four return springs 207 are arranged inside the rotating cylinder 201, and one end of each sliding rod 203 away from the rotating cylinder 201 is fixedly connected to an arc plate 204. The inner wall of the protective shell 3 is fixedly connected to a driving motor 7, and the driving motor 7 is electrically connected to the button controller 4 through a wire. The output end of the driving motor 7 is fixedly connected to a rotating rod 8, which can be controlled by the button controller 4 and provide rotational power to the inner wall fitting cleaning mechanism 2. By providing the rotating rod 8, the rotational power of the driving motor 7 can be transmitted.

[0027] The outer surface of each arc plate 204 is fixedly connected with a plurality of identical scrapers 205, and the end of each sliding rod 203 away from the arc plate 204 is fixedly connected with a limit plate 206, and the two ends of each return spring 207 are respectively in contact with the inner wall of the rotating cylinder 201 and the inner wall of the limit plate 206, and the left end of the rotating rod 8 is fixedly connected with a threaded sleeve 9, and the inner wall of the threaded sleeve 9 is threadedly connected with the outer surface of the elastic gooseneck tube 1, and the outer surface of the output end of the driving motor 7 and the outer surface of the rotating rod 8 are jointly fixedly connected with a coupling 10.

[0028] The outer surface of each limit plate 206 is slidably connected to the inside of the rotating cylinder 201, and the inner wall of the protective shell 3 is fixedly connected with an auxiliary bearing 11. The inner ring of the auxiliary bearing 11 is fixedly connected to the outer surface of the rotating rod 8. By providing the auxiliary bearing 11, the inner wall of the protective shell 3 and the rotating rod 8 can be connected, thereby increasing the smoothness of the rotation of the rotating rod 8.

[0029] The working principle of the utility model is: when using, according to the length of the pipe to be cleared, try to choose an elastic gooseneck tube 1 that is slightly longer than the pipe or threadedly splice multiple elastic gooseneck tubes 1, then install the rotating cylinder 201 on the left end of one or more elastic gooseneck tubes 1, and install the threaded sleeve 9 on the right end of one or more elastic gooseneck tubes 1. After the installation is tight, the threaded connection between the elastic gooseneck tube 1 and the rotating cylinder 201 and the threaded sleeve 9 will not be disconnected due to the rotation of the drive motor 7, and before using the inner wall fitting cleaning mechanism 2, try to ensure that the diameter formed by the multiple scrapers 205 on the surface of the four arc plates 204 is larger than the inner diameter of the pipe to be cleared, so as to ensure that the scraper 205 can fit tightly against the inner wall of the pipe, and then before starting to use the clearing device, first press the four arc plates 204 toward the inside of the rotating cylinder 201, at this time the limit plate 206 will compress the corresponding return spring 207, and at the same time all the arc plates 204 and scrapers 20 5 gradually leans toward the rotating cylinder 201 until the outer scraper 205 can gradually enter the interior of the pipeline. After the inner wall fitting cleaning mechanism 2 is inserted into the pipeline to be dredged as much as possible, one hand holds a hand grip rod 5 and an anti-skid sleeve 6, and the other hand operates the button controller 4 to start controlling the driving motor 7 to energize and drive the rotating rod 8 and the threaded sleeve 9 to rotate, and the user gradually pushes the hand grip rod 5 and the anti-skid sleeve 6 to the deep direction of the pipeline. At the same time, the elastic gooseneck tube 1 transmits the rotation of the threaded sleeve 9 to the entire inner wall fitting cleaning mechanism 2 structure, and the spiral tower drill bit 202 dredges the important blockage in the middle part of the pipeline, and then the scrapers 205 on the outer surfaces of each arc plate 204 stick to the inner wall of the pipeline to break up and clean the inner wall blockage, thereby achieving a more comprehensive pipeline dredging. The design of the pipeline dredging device for the entire engineering construction effectively solves the problem that the pipeline cleaning and dredging effect is relatively general due to the lack of a cleaning structure that can fit and clean the inner wall of the pipeline.
