Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, and particularly relates to a pipeline cleaning tool. Background Art

[0002] To ensure the normal operation of the building rainwater drainage system, it is necessary to regularly clean the rainwater pipes on the building exterior wall to avoid blockage of the pipes caused by leaves, garbage and other sundries adhering to the inner wall of the pipes, resulting in blocked rainwater discharge or damage to the building structure caused by rainwater overflow; it can also avoid the corrosion damage to the pipe components caused by various chemical substances in the rainwater acting on the inner wall of the pipes for a long time, and extend the service life of the pipes.

[0003] In the prior art, when there are fewer blockages in the pipeline, the method of using water flow impact is usually adopted to impact the sundries on the inner wall of the rainwater pipeline, and in combination with a long-handled net bag or hook, the blockages in the pipeline are fished out; when there are more blockages in the pipeline, it is necessary to combine a high-pressure water gun and an electric spiral brush to dredge and clean the pipeline; however, for pipelines with a more tortuous and complex internal structure, dirt and sediment are easily attached to the inner wall of the pipeline and cannot be effectively cleaned. Therefore, the present application provides a pipeline cleaning tool. Summary of the Utility Model

[0004] In order to solve the above deficiencies in the prior art, the purpose of the present utility model is to provide a pipeline cleaning tool, which can extend into the bent part inside the pipeline and efficiently clean the dirt and sediment attached to the inner wall, thereby avoiding the corrosion damage caused by the long-term attachment of sludge containing chemical substances to local positions of the pipeline.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] A pipeline cleaning tool is provided, which includes a cleaning cylinder, an extension rod, a scraping disc and a runner; runners are respectively rotatably installed on both sides inside the cleaning cylinder, an extension rod is fixedly installed at the top of the cleaning cylinder, and a plurality of scraping discs are fixedly installed at equal intervals on the outer side of the extension rod. The scraping disc is made of an elastic material, and the outer side surface of the runner and the outer edge of the scraping disc can both abut against the inner side surface of the pipeline. A power traction component is arranged inside the cleaning cylinder.

[0007] In the present application, as an optional technical solution for the structure of the power traction component: the power traction component is a counterweight block, and the counterweight block is arranged inside the cleaning cylinder.

[0008] In this application, for the structure of the power traction assembly, another alternative technical solution is as follows: The power traction assembly includes a motor, which is inserted into the insertion cavity on the side of the cleaning cylinder and fixedly connected to the end cover at the end of the insertion cavity. A driving gear is installed on the output shaft of the motor; the sides of the two rotating wheels in the cleaning cylinder are in contact with each other and are frictionally connected for transmission. A transmission wheel is rotatably installed in the cleaning cylinder, and the transmission wheel is frictionally connected to the outer side of one of the rotating wheels. The transmission wheel and the driving gear are meshed and driven by a transmission belt.

[0009] Further, a plurality of shaft rods are detachably installed on the side of the cleaning cylinder, and the rotating wheel and the transmission wheel are respectively rotatably connected to their corresponding shaft rods.

[0010] Further, a scraping edge is provided on the side of the cleaning cylinder, and the outer side of the rotating wheel is tightly connected to the scraping edge.

[0011] Further, a hanging ring is integrally formed at the end of the extension rod, a rope is connected to the hanging ring, and the other end of the rope extends towards the outside of the pipeline.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For the pipeline cleaning tool exemplified by the present utility model, the scraping disc uses an elastic material, such as rubber or polyurethane plastic; by utilizing the elastic deformation of the scraping disc, when the cleaning cylinder passes through the bent part inside the pipeline, the scraping disc can fully scrape and clean the inner wall of the pipeline, avoiding the blockage of the pipeline caused by the attachment of leaves, garbage and other sundries on the inner wall of the pipeline, which may lead to the blockage of the accumulated rainwater discharge or the damage of the building structure caused by the overflow of rainwater.

[0014] 2. For the pipeline cleaning tool exemplified by the present utility model, by utilizing the gravity of the counterweight, the cleaning cylinder obtains an initial acceleration and continuously accumulates kinetic energy during the falling process, driving the cleaning cylinder to smoothly fall along the pipeline with a relatively tortuous and complex internal structure. During this process, the scraping disc is used to clean the dirt and sediment attached to the inner wall of the pipeline, avoiding the corrosion damage caused by the long-term attachment of sludge containing chemical substances to local positions of the pipeline.

[0015] 3. For the pipeline cleaning tool exemplified by the present utility model, the transmission wheel is driven to rotate, driving the two rotating wheels to rotate synchronously and reversely, actively controlling the position of the cleaning cylinder inside the pipeline, increasing the moving control effect of the cleaning cylinder inside the pipeline, improving the pipeline cleaning efficiency, enabling the tool to be put into use at the bottom position of the pipeline, and having higher operation convenience.

[0027] Embodiment 1:

[0028] As Figure 1 shown, this embodiment provides a pipeline cleaning tool, which includes a cleaning cylinder 11, an extension rod 12, and a scraping plate 13; an extension rod 12 is fixedly installed at the top of the cleaning cylinder 11, and a plurality of scraping plates 13 are fixedly installed at equal intervals on the outer side of the extension rod 12. The outer edges of the scraping plates 13 can all be in contact with the inner side surface of the pipeline, and a power traction component is arranged inside the cleaning cylinder 11.

[0029] Among them, the scraping plate 13 is made of an elastic material, such as rubber or polyurethane plastic; by using the elastic deformation of the scraping plate 13, when the cleaning cylinder 11 passes through the bent part inside the pipeline, the scraping plate 13 can fully scrape and clean the inner wall of the pipeline, avoiding the blockage of the pipeline caused by the attachment of leaves, garbage, and other sundries on the inner wall of the pipeline, or the damage of the building structure caused by the overflow of rainwater due to the blocked drainage of accumulated rain.

[0030] As Figure 2 shown, a hanging ring is integrally formed at the end of the extension rod 12, a rope is connected to the hanging ring, and the other end of the rope extends towards the outside of the pipeline. By pulling the rope, the cleaning cylinder 11 can be drawn out of the pipeline for repeated use.

[0031] In this embodiment, the power traction component is a counterweight block, and the counterweight block is arranged inside the cleaning cylinder 11.

[0032] When using the pipeline cleaning tool of this application, the cleaning cylinder 11 is put into the pipeline from the top of the pipeline. By using the gravity of the counterweight block, the cleaning cylinder 11 obtains an initial acceleration and continuously accumulates kinetic energy during the falling process, driving the cleaning cylinder 11 to smoothly fall along the pipeline with a relatively tortuous and complex internal structure. During this process, the scraping plate 13 is used to clean the dirt and sediment attached to the inner wall of the pipeline, avoiding the corrosion damage caused by the long-term attachment of sludge containing chemical substances to local positions of the pipeline.

[0033] Since there are multiple scraping plates 13 provided, sludge scraped from the inner wall of the pipeline can be stored between the multiple scraping plates 13, thereby enhancing the usage effect of the pipeline cleaning tool.

[0034] To enhance the stability of the cleaning cylinder 11 as it descends along the pipeline extension path, as Figure 1 shown, on both inner sides of the cleaning cylinder 11, rotating wheels 21 are respectively installed in a rotating manner. The outer side surface of the rotating wheel 21 abuts against the inner side surface of the pipeline, thereby restricting the movement state of the cleaning cylinder 11 within the pipeline, reducing the degree of rubbing between the overall tool and the inner wall of the pipeline during the process of descending along the tortuous pipeline extension path, and avoiding adverse effects on the descending stability and descending speed of the cleaning cylinder 11.

[0035] Embodiment Two:

[0036] Features identical to those in Embodiment One will not be elaborated here. The different solution in this embodiment from that in Embodiment One lies in: as Figure 1 and Figure 3 shown, in this embodiment, the power traction assembly includes a motor 24. The motor 24 is inserted into the insertion cavity 112 on the side of the cleaning cylinder 11 and is fixedly connected to the end cover 23 at the end of the insertion cavity 112. A driving gear 25 is installed on the output shaft of the motor 24; a transmission wheel 22 is rotatably installed in the cleaning cylinder 11. The transmission wheel 22 is frictionally connected to the outer side surface of one of the rotating wheels 21. The side parts of the two rotating wheels 21 in the cleaning cylinder 11 abut against each other and are frictionally connected. The transmission wheel 22 and the driving gear 25 are meshed and driven by a transmission belt 26.

[0037] Among them, a scraping edge 111 is provided on the side of the cleaning cylinder 11. The outer side surface of the rotating wheel 21 is tightly connected to the scraping edge 111, keeping the surface of the rotating wheel 21 at the inner side position of the cleaning cylinder 11 clean and reducing the adverse effects on the frictional transmission between the two rotating wheels 21.

[0038] Start the motor 24, control the rotation of the driving gear 25. Under the action of the transmission belt 26, drive the transmission wheel 22 to rotate. Utilize the frictional connection between the transmission wheel 22 and one of the rotating wheels 21 to drive the rotation of this rotating wheel 21, and utilize the side parts of the two rotating wheels 21 in the cleaning cylinder 11 to abut against each other and be frictionally connected, so that the two rotating wheels 21 rotate synchronously in opposite directions, actively control the position of the cleaning cylinder 11 within the pipeline, enhance the moving control effect of the cleaning cylinder 11 within the pipeline, and improve the pipeline cleaning efficiency.

[0039] Compared with the technical solution in Embodiment One, in this embodiment, by actively controlling the rotation of the two rotating wheels 21, the tool can be put into use at the bottom position of the pipeline, and the operation convenience is higher.

[0040] To increase the disassembly convenience of the runner 21 and the transmission wheel 22 within the cleaning cylinder 11, as Figure 2 shown, a plurality of shaft rods 14 are detachably installed on the side of the cleaning cylinder 11, such that the runner 21 and the transmission wheel 22 are respectively rotatably connected to their corresponding shaft rods 14. After placing the runner 21 and the transmission wheel 22 into the cleaning cylinder 11, the corresponding plurality of shaft rods 14 are inserted into the cleaning cylinder 11, thereby increasing the disassembly convenience of the runner 21 and the transmission wheel 22.

[0041] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, a technical solution formed by mutually replacing the above features with technical features (but not limited to) having similar functions disclosed in the present application.

[0042] Except for the technical features described in the specification, the remaining technical features are well-known to those skilled in the art. To highlight the innovative features of the present utility model, the remaining technical features are not described herein again.
