[0024] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a pipe outer wall rust removal and cleaning device. The worker holds the handle and starts the motor to make the grinding belt rotate, so as to grind or clean the pipe. This device is highly portable and similar to mature electrical tools such as handheld electric drills and angle grinders. It is easy to carry and has high work efficiency.

[0027] Specifically, the handheld component 100 includes a handle 100a, which is convenient for operators to hold and operate. A power supply component 101, including a motor 101a, is fixedly connected to the bottom surface of the end of the handle 100a. The top of the motor 101a is fixedly connected to one end of the handle 100a, and a battery 101g is fixedly connected to the other end of the handle 100a. An output shaft 101c is fixedly connected to the top of the motor 101a. A drive wheel 101e is rotatably connected to the outer wall of the output shaft 101c. A grinding belt 102 is provided on the outer wall of the drive wheel 101e, and a pipe 103 is sleeved on the other end of the grinding belt 102.

[0028] Furthermore, the battery 101g is electrically connected to the motor 101a, and the motor 101a is started by the power supplied by the battery 101g.

[0029] Preferably, a bolt 101b is rotatably connected to the outer periphery of the motor 101a. The bolt 101b is used to rotatably connect to the bottom of the handle 100a away from the battery 101g, thereby fixing the motor 101a and the handle 100a.

[0030] In this device, the handheld component 100 encapsulates conventional components such as wiring, switches, interfaces, and controllers. A switch is located on the top of the handle 100a, and a reversing switch for the motor 101a is located on the side. Bolts 101b for mounting the motor are located on the top and bottom of the ring. The motor 101a is fixed to the handle 100a using bolts 101b, resulting in a simple and durable structure. A battery 101g can also be installed at the tail of the handle 100a, which also has a standard AC220V power supply interface. The motor 101a uses a DC 12V motor commonly used in the power tool industry. The power supply and control signals for the motor 101a are connected to the handle 100a using a universal socket structure, enabling power supply and signal transmission. The battery 101g uses a conventional lithium-ion power supply component, with customizable capacity. The battery 101g powers the motor 101a when connected to the handle 100a, or it can be used without the battery 101g, directly powering the motor 101a through the AC220V power supply interface at the tail of the handle 100a. The choice can be flexible depending on the usage scenario and location.

[0031] Example 2

[0032] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment fixes the position of the output shaft and the drive wheel by the snap-fit ​​of the keyway and the key strip, and fixes the position of the grinding belt by the guide roller, the guide shaft and the drive wheel, which can better clean and grind the pipe.

[0033] Specifically, an output shaft 101c is rotatably connected to the center of the surface of the motor 101a, and a drive wheel 101e is rotatably connected to the top of the output shaft 101c. The output shaft 101c drives the drive wheel 101e to rotate synchronously, and the drive wheel 101e is rotatably connected to the surface of the handle 100a.

[0034] Furthermore, a keyway 101d is provided on the top of the output shaft 101c, and a key bar 101f is fixedly connected to the corresponding position of the drive wheel 101e and the keyway 101d. The keyway 101d and the key bar 101f are engaged to fix the output shaft 101c and the drive wheel 101e.

[0035] Preferably, a guide roller 100b is fixedly connected to the end of the handle 100a away from the battery 101g. Three guide rollers 100b are arranged in a circumferential array with the output shaft 101c as the center. A guide shaft 100c is inserted into the top of each guide roller 100b. There is a certain gap between the drive wheel 101e and the guide roller 100b. A grinding belt 102 is placed between the drive wheel 101e and the guide roller 100b. The thickness of the grinding belt 102 is less than the distance between the drive wheel 101e and the guide roller 100b.

[0036] The operator engages the key bar 101f on the drive wheel 101e with the keyway 101d on the top of the output shaft 101c, thus fixing the drive wheel 101e and the output shaft 101c together. Then, the guide shaft 100c of the guide roller 100b is removed, placing the grinding belt 102 between the drive wheel 101e and the guide roller 100b. After fixing the position of the grinding belt 102, the guide shaft 100c is re-inserted into the guide roller 100b to fix the grinding belt 102 vertically. The other end of the grinding belt 102 is fitted onto the outer wall of the pipe 103. The worker holds the handle 100a and starts the motor 101a to clean and grind the pipe 103 through the grinding belt 102. It can be used on pipes of different diameters and can automatically perform rust removal and cleaning work on the outer wall of variable diameter pipes. Moreover, the working surface of the grinding belt 102 is on the back of the pipe 103 relative to the worker, which has an inherent advantage for cleaning and grinding pipes installed on walls, corners, trenches and other restricted work positions.

[0037] Example 3

[0038] Reference Figure 1 , Figure 2 and Figure 3 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment adds a coating material to the inner ring of the grinding belt, which can remove rust or clean pipes of different materials, thus enriching the application scenarios of this device and making it more adaptable.

[0039] Specifically, the end of the grinding belt 102 away from the guide roller 100b is used to clean the grinding pipe 103, which can be made of metal or plastic, etc.

[0040] Furthermore, the grinding belt 102 is made of materials with good tensile strength, such as nylon and canvas. The inner ring side of the grinding belt 102 is sprayed with abrasive to form a sandpaper surface. Alternatively, the inner ring side of the grinding belt 102 may not be coated with any material, which can meet the specific needs of rust removal and cleaning.

[0041] Preferably, the grinding belt 102 is provided with a soft link, so that the grinding belt 102 changes from a ring structure to a belt structure when it is not under stress.

[0042] Workers choose whether to remove rust or clean pipe 103 based on the work scenario. For rust removal of metal pipes, workers need to select abrasive belt 102 with abrasive coating on the inner ring. The recommended base material for abrasive belt 102 is sturdy materials such as nylon or canvas. Abrasive belt 102 functions similarly to sandpaper. The grit number of the inner ring of abrasive belt 102 is determined based on the degree of polishing required. If the metal pipe is heavily corroded, a lower grit abrasive belt 102 is used first, gradually replacing it with higher grit belts in batches to ensure polishing quality. For cleaning metal or non-metal pipes, workers need to select abrasive belt 102 without coating. The type of abrasive belt 102 depends on the pipe material, such as plastic or rubber pipes. 102 recommends using soft materials such as cotton cloth, gauze, or canvas. The connection method uses Velcro. For cleaning metal pipes, the grinding belt 102 uses a chain shaft structure. Open the connecting mechanism on the grinding belt 102; the belt changes from a loop to a strip. The worker manually first passes the grinding belt 102 through the back of the pipe 103, then manually guides it through the gap between the drive wheel 101e and the guide roller 100b, exiting from the other end. Finally, the grinding belt 102 is connected to form a closed loop. Alternatively, the guide shaft 16 and guide roller 100b can be removed from the handle 100a, and the grinding belt 102 can be directly fitted onto the drive wheel 101e. Finally, the guide shaft 100c and guide roller 100b are reinstalled.

[0043] The worker holds handle 100a facing pipe 103 and pulls the grinding belt 102 taut backward. Then, the switch is pressed to start motor 101a, which drives drive wheel 101e and grinding belt 102 to rotate synchronously. The grinding belt 102 begins to slide and rub against the back of pipe 103, performing rust removal or cleaning. The worker can adjust the tension of the grinding belt 102 according to the work situation. The grinding belt 102 is made of flexible materials such as nylon, canvas, or gauze. When the worker slightly tilts handle 100a upward and slowly drags it, the grinding belt 102 slides upward synchronously on pipe 103. Similarly, downward, left, and right movements are also possible. Furthermore, the worker holds handle 100a and slowly rotates it around pipe 103, thus covering the entire circumferential surface of pipe 103. By turning the handle 100a and moving it along the axis of the pipe 103, the rust removal and cleaning of the entire outer wall of the pipe 103 can be achieved. The drive wheel 101e can be replaced with a wheel-shaped brush. After removing the guide roller 100b and guide shaft 100c and turning on the motor 101a, this device is similar to an angle grinder and can also complete the rust removal and cleaning of the outer wall of the pipe 103. It can also achieve the desired effect when dealing with large-diameter pipes 103.
