Technical Field
[0001] This utility model relates to the field of water conservancy pipeline polishing and rust removal technology, and more specifically, to a retractable pipeline polishing device. Background Technology
[0002] With the continuous development of modern water conservancy projects, water transmission pipelines play a vital role in water supply, drainage, irrigation and other water conservancy projects. However, during long-term operation, rust often forms inside the water transmission pipelines due to factors such as water quality, water flow erosion and external corrosion. This not only affects the water transmission efficiency of the pipelines, but may also lead to pipeline leaks, resulting in waste of water resources and environmental pollution.
[0003] Traditional rust removal of water pipelines mainly relies on manual labor, which is not only time-consuming and labor-intensive, but also poses a high safety risk. Moreover, due to the different inner diameters of water pipelines, existing pipeline polishing devices are not convenient for polishing water pipelines with different inner diameters, resulting in a limited range of applications. In view of this, this utility model proposes a telescopic pipeline polishing device. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a retractable pipe polishing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic pipe polishing device, comprising a housing, a rotary motor installed inside the housing, a rotating rod fixedly installed at the output end of the rotary motor, a rotating block installed at one end of the rotating rod, two polishing structures installed on the rotating block, a telescopic walking structure installed on the housing, and a slag discharge structure installed at one end of the housing.
[0006] To facilitate polishing and grinding of water pipes with different inner diameters, preferably, the polishing structure includes two electric push rods, which are respectively fixedly installed on both sides of the outer wall of the rotating block. The output ends of the two electric push rods are fixedly provided with support plates, and stepper motors are fixedly installed on the support plates. The output ends of the stepper motors are fixedly provided with polishing discs.
[0007] To enable the device to move inside pipes of different inner diameters, preferably, the telescopic walking structure includes several sleeves, which are respectively arranged in a ring and fixedly distributed on the outer wall of the outer shell. A sleeve rod is slidably disposed inside each sleeve, with a drive wheel at one end of two sleeve rods and a walking wheel at one end of the other two sleeve rods. A drive motor is mounted on each drive wheel, and the output end of the drive motor is connected to the drive wheel. A movable block is disposed inside each sleeve and at one end of a sleeve rod. The movable block is slidably connected inside the sleeve, and a compression spring is disposed on one side of the movable block. The two ends of the compression spring are fixedly connected to the movable block and the inner wall of the sleeve, respectively.
[0008] In order to remove the rust residue generated after polishing the inside of the water conservancy pipeline, preferably, the rust removal structure includes a connecting rod, which is fixedly installed at one end of the outer shell, and an air bladder is provided at one end of the connecting rod. An air pump is installed on the surface of the outer shell, and a connecting hose is provided at the output end of the air pump. One end of the connecting hose is connected to the air bladder.
[0009] The technical effects and advantages of this utility model are as follows:
[0010] 1. By setting up a telescopic walking structure, the sleeve slides inside the sleeve and the compression spring is compressed by the movable block. According to the elastic potential energy of the compression spring, the walking wheel and the drive wheel can be made to fit against the inner wall of the water pipe according to the inner diameter of the water pipe. Then the drive motor drives the drive wheel to rotate, so that the device can move inside water pipes with different inner diameters, thus improving the range of use.
[0011] 2. By setting up a polishing structure, the output end of the electric push rod drives the support plate to extend, so that the polishing plate at the output end of the stepper motor fits against the inner wall of the water pipe, which is convenient for polishing water pipes with different inner diameters. The stepper motor drives the polishing plate to rotate, polishing the rusted parts of the water pipe.
[0012] 3. By setting up a slag discharge structure, gas is delivered to the inside of the airbag through a connecting hose using an air pump, causing the airbag to expand. The outer wall of the expanded airbag is tightly attached to the inner wall of the water pipe. As the device moves continuously inside the water pipe, the expanded airbag discharges the rust residue inside the water pipe, preventing the rust residue from causing any problems inside the water pipe.
[0013] In summary, this utility model, through the combined use of the above-mentioned structures, facilitates polishing and rust removal operations on water pipes of different inner diameters, and makes it easy to remove the generated rust residue, resulting in good performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] As attached Figure 1-4 The telescopic pipe polishing device shown includes a housing 1, a rotary motor 2 installed inside the housing 1, a rotating rod 3 fixedly installed at the output end of the rotary motor 2, a rotating block 4 installed at one end of the rotating rod 3, two polishing structures installed on the rotating block 4, a telescopic walking structure installed on the housing 1, and a slag discharge structure installed at one end of the housing 1.
[0021] Specifically, in this structure, the rotary motor 2 installed inside the outer shell 1 can drive the rotating rod 3 to rotate, causing the rotating block 4 to rotate, thereby driving the two polishing structures to polish and remove rust from the inner wall of water pipes with different inner diameters. The outer shell 1 is equipped with a telescopic walking structure, which can move inside water pipes with different inner diameters. After the slag discharge structure is inflated, it fills the entire inner wall of the water pipe. As the device moves, it can discharge the rust slag polished inside the water pipe from the inside of the water pipe.
[0022] The specific structure is shown below:
[0023] In the above embodiments, as shown in the appendix Figure 1 , 4As shown, the polishing structure includes two electric push rods 5, which are fixedly installed on both sides of the outer wall of the rotating block 4. The output ends of the two electric push rods 5 are fixedly provided with support plates 6, and stepper motors 7 are fixedly installed on the support plates 6. The output ends of the stepper motors 7 are fixedly provided with polishing discs 8.
[0024] Specifically, in this structure, in order to facilitate the polishing and rust removal of the inner walls of water pipes with different inner diameters, the output end of the electric push rod 5 drives the support plate 6 to extend, so that the polishing plate 8 at the output end of the stepper motor 7 fits against the inner wall of the water pipe, which facilitates the grinding and polishing of water pipes with different inner diameters. Then, the stepper motor 7 drives the polishing plate 8 to rotate, polishing and grinding the rusted parts of the water pipe. During the rotation of the rotating block 4, the rotating polishing plate 8 can perform a uniform polishing operation on the inner wall of the water pipe.
[0025] In the above embodiments, as shown in the appendix Figure 1 , 2 As shown in Figure 3, the telescopic walking structure includes several sleeves 9, which are fixedly distributed in a ring on the outer wall of the outer shell 1. Sleeve rods 10 are slidably arranged inside the sleeves 9. Two sleeve rods 10 are provided with drive wheels 11 at one end, and two other sleeve rods 10 are provided with walking wheels 12 at one end. Drive motors 13 are installed on the drive wheels 11, and the output end of the drive motors 13 is connected to the drive wheels 11. A movable block 14 is provided inside the sleeves 9 and at one end of the sleeve rods 10. The movable block 14 is slidably connected inside the sleeves 9, and a compression spring 15 is provided on one side of the movable block 14. The two ends of the compression spring 15 are fixedly connected to the movable block 14 and the inner wall of the sleeves 9, respectively.
[0026] Specifically, in this structure, the sleeve rod 10 slides and extends inside the sleeve 9 and compresses the compression spring 15 through the movable block 14. Based on the elastic potential energy of the compression spring 15, the traveling wheel 12 and the drive wheel 11 can be made to fit against the inner wall of the water pipe according to the inner diameter of the water pipe. Then, the drive motor 13 drives the drive wheel 11 to rotate, so that the device can move inside water pipes with different inner diameters.
[0027] In the above embodiments, as shown in the appendix Figure 1 As shown, the slag discharge structure includes a connecting rod 16, which is fixedly installed at one end of the outer casing 1. An air bladder 17 is provided at one end of the connecting rod 16. An air pump 18 is installed on the surface of the outer casing 1. A connecting hose 19 is provided at the output end of the air pump 18. One end of the connecting hose 19 is connected to the air bladder 17.
[0028] Specifically, in this structure, the rust residue after the inner wall of the water pipe is polished will be inside the water pipe. At this time, the inflation and deflation pump 18 delivers gas to the inside of the air bag 17 through the connecting hose 19, causing the air bag 17 to inflate. The outer wall of the inflated air bag 17 is tightly attached to the inner wall of the water pipe. As the device moves continuously inside the water pipe, the inflated air bag 17 discharges the rust residue inside the water pipe, preventing the rust residue from being inside the water pipe and causing any impact.
[0029] The air pump 18 can inflate and deflate the airbag 17. After the airbag 17 is used, the air can be extracted from the airbag 17 by the air pump 18. It is worth noting that the airbag 17 in the attached figure is in an uninflated state. After the airbag 17 is fully inflated, it can fill the entire inner wall of the water conservancy pipeline.
[0030] Working principle of this utility model:
[0031] This application provides a retractable pipe polishing device, which can polish the rusted parts of the inner wall of a circular water pipe. In specific operation;
[0032] First, the telescopic walking structure utilizes the sliding of the sleeve 10 inside the sleeve 9 and the compression spring 15 to be compressed by the movable block 14. According to the elastic potential energy of the compression spring 15, the walking wheel 12 and the drive wheel 11 can be made to fit against the inner wall of the water pipe according to the inner diameter of the water pipe. Then, the drive motor 13 drives the drive wheel 11 to rotate, so that the device can move inside water pipes with different inner diameters.
[0033] The polishing structure uses the output end of the electric push rod 5 to drive the support plate 6 to extend, so that the polishing plate 8 at the output end of the stepper motor 7 fits against the inner wall of the water pipe, which is convenient for polishing water pipes with different inner diameters. The stepper motor 7 drives the polishing plate 8 to rotate, polishing the rusted parts of the water pipe.
[0034] The slag discharge structure uses an air pump 18 to deliver gas through a connecting hose 19 to the inside of the airbag 17, causing the airbag 17 to inflate. The outer wall of the inflated airbag 17 is tightly attached to the inner wall of the water pipe. As the device moves continuously inside the water pipe, the inflated airbag 17 discharges the rust residue inside the water pipe, preventing the rust residue from causing any impact inside the water pipe.
[0035] Furthermore, the device can drive the rotating rod 3 to rotate through the rotating motor 2 inside the outer shell 1, thereby causing the rotating block 4 to rotate. This, in turn, drives the two polishing structures to polish and remove rust from the rusted parts of the inner walls of water pipes with different inner diameters. The device can move inside water pipes with different inner diameters through the telescopic walking structure set on the outer shell 1. After the slag discharge structure is inflated, it fills the entire inner wall of the water pipe. As the device moves, it can discharge the rust slag polished inside the water pipe from the inside of the water pipe.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
