Description

Technical Field

[0001] This utility model belongs to the field of pipe wall cleaning technology, and specifically relates to a pipe wall cleaner. Background Technology

[0002] In industrial production and municipal maintenance, the maintenance of metal and non-metal pipes is of paramount importance. Among them, cleaning, rust removal, paint removal and surface polishing of the pipe exterior are common and necessary procedures.

[0003] Traditional methods of treating the outer walls of pipes often rely on manual polishing using hand tools such as sandpaper and wire brushes. This method is not only labor-intensive and inefficient, but also makes it difficult to maintain consistent cleaning results. Especially for long-distance, large-scale pipeline projects, the labor and time costs are extremely high. Utility Model Content

[0004] The purpose of this invention is to provide a pipe wall cleaner to solve the problem of pipe grinding in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pipe wall cleaner includes: a cylindrical barrel body with a hollow groove and an assembly end, the assembly end being in the opening direction of the hollow groove; a mounting block detachably mounted on the inner wall of the hollow groove, a brush head being disposed on the mounting block facing one end of the hollow groove, the brush head being used to contact the pipe wall to be cleaned; a connecting end located at the bottom of the barrel body for connecting a power tool; and an end cap detachably connected to the assembly end, the end cap being used to hold the mounting block in place.

[0006] Preferably, the end cap is wider at the top and narrower at the bottom. This tapered design increases the top area of ​​the end cap, providing a more stable support point for the fingers during rotation and reducing the risk of slippage. This design significantly improves grip comfort, especially for users with weaker hand strength or those operating in wet environments.

[0007] Preferably, the outer wall of the assembly end has an external thread structure, and the inner wall of the end cap has an internal thread structure. The detachable engagement of the assembly end and the end cap is fixed by a threaded rotation connection. The external thread of the assembly end and the internal thread of the end cap mesh with each other to achieve a fixed assembly effect. Simultaneously, the end cap's shape, which is wider at the top and narrower at the bottom, allows for quick installation and removal of the end cap.

[0008] Preferably, a stepped hole is provided near the wide end of the end cap, and after the end cap is assembled with the assembly end, the bottom end of the stepped hole and the top end of the assembly end are in contact with each other.

[0009] Preferably, the inner wall of the hollow groove is spirally provided with an installation groove, the tail end of the installation block matches the installation groove, and the installation block is spirally arranged to cooperate with the installation groove for installation.

[0010] Preferably, the cross-section of the mounting block is trapezoidal, wherein the small end of the trapezoid is spirally provided with a positioning groove, the brush head is spirally arranged in the positioning groove, the hollow groove is divided into three groups of spaces by a dividing line, and the length of the brush head is close to the dividing line.

[0011] Preferably, the brush head is made of plastic. The brush head is also made of metal. The spiral arrangement of the brush heads adapts to different materials: whether the spiral brush head is made of plastic or metal, it uses a material with elasticity or toughness (such as highly elastic soft rubber or tough plastic, stainless steel wire), which can automatically adjust the contact force according to the pipe material (such as metal or plastic), avoiding hard bristles scratching soft pipe walls or soft bristles failing to clean hard dirt. The appropriate material of the brush head is rotated according to the specific polishing needs.

[0012] Preferably, the mounting block is made of ductile metal, and pressure is applied to both ends of the positioning groove to fix the brush head. The purpose of using ductile metal is to forge the mounting block into a spiral shape to facilitate assembly with the mounting groove; and the pressure applied to both ends of the positioning groove to fix the brush head is achieved by hydraulically pressing the two ends of the positioning groove, so that the brush head is fixed inside the positioning groove. This method allows for the automated production of mounting blocks with brush heads.

[0013] Preferably, the connecting end is a hexagonal prism, and the connecting end is fixed to the bottom of the barrel using a set screw technique. The hexagonal prism shape of the connecting end facilitates the connection of power tools. Standard power tool products all use hexagonal connectors to achieve standardization. The set screw, through its tail design (such as a flat or pointed tail), is directly embedded into the axial positioning groove or hole of the hexagonal prism, forming mechanical interference and completely eliminating axial movement. The set screw is a commonly used processing technique in the market, which will not be described in detail here. Its purpose is to lock the connecting end to the bottom of the barrel.

[0014] The technical solution of this utility model has the following beneficial effects: 1. The connecting end is attached to a power tool. When the spirally arranged brush head rotates, the tilt angle of each bristle will form dynamic contact with the outer wall of the pipe. Under the high-speed rotation of the barrel, the brush head can quickly polish and clean the outer wall of the pipe, and can remove rust from metal pipes.

[0015] 2. The brush head is designed to be detachable. Long-term use may cause the brush head to lose its polishing effect. The mounting block can be quickly removed by rotating it to replace the other mounting block, thus allowing the brush head to be replaced. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] Example 1: refer to Figures 1-6 A pipe wall cleaner, comprising: The barrel body 10 is cylindrical and includes a hollow groove 101 and an assembly end 103, with the assembly end 103 in the opening direction of the hollow groove 101. Mounting block 40 is detachably mounted on the inner wall of hollow trough 101. A brush head 402 is provided on the end of mounting block 40 facing hollow trough 101. The brush head 402 is used to contact the pipe wall to be cleaned. The connecting end 30, located at the bottom of the barrel 10, is used to connect power tools. End cap 20 is detachably connected to assembly end 103 and is used to hold the mounting block 40 in place.

[0026] In the above scheme, when using this device, the connecting end 30 is connected to a power tool. The power tool can be any electric rotary machine adapted to the connecting end 30, including a handheld drill or a tabletop electric rotary tool. Regardless of which type of tool is used, the purpose is to rotate the barrel 10. Because the barrel 10 is cylindrical, the geometric symmetry of the cylinder ensures that the centrifugal force is evenly distributed radially during high-speed rotation, avoiding stress concentration. Before starting the power tool, the pipe to be cleaned needs to be inserted into the barrel 10. The hollow groove 101 of the tube, which is the outer wall of the tube, contacts the brush head 402. Under the high-speed rotation of the barrel 10, the brush head 402 can quickly polish and clean the outer wall of the tube, and can remove rust from metal tubes. The end cap 20 is connected to the assembly end 103 in a detachable manner. Since the mounting block 40 is detachably installed on the inner wall of the hollow groove 101, the end cap 20 can be used to prevent the mounting block 40 from being thrown out due to centrifugal force when the barrel 10 is rotating. Moreover, by first removing the end cap 20 and then taking out the mounting block 40, the mounting block 40 can be quickly replaced. It should be noted that the purpose of replacing the mounting block 40 in this solution is to replace the brush head 402. The brush head 402 will wear out during high-speed grinding, and long-term use will lead to a deterioration in the grinding effect of the brush head 402. By quickly removing the mounting block 40, another mounting block 40 can be replaced, thereby replacing the brush head 402. Here, only the mounting block 40 needs to be replaced. The brush head 402 is fixed together with the mounting block 40 through processing and is a consumable unit.

[0027] Preferred reference Figure 1 and Figure 4 The end cap 20 has a tapered shape, wider at the top and narrower at the bottom. This tapered design increases the top surface area of ​​the end cap 20, providing a more stable support point for the fingers during rotation and reducing the risk of slippage. This design significantly improves grip comfort, especially for users with weaker hand strength or those operating in wet environments.

[0028] Further reference Figures 2-6 The outer wall of the assembly end 103 is provided with an external thread structure, and the inner wall of the end cover 20 is provided with an internal thread structure. The detachable engagement of the assembly end 103 and the end cover 20 is fixed by a threaded rotation connection. The external thread of the assembly end 103 and the internal thread of the end cover 20 engage with each other to achieve a fixed assembly effect. Simultaneously, the shape of the end cover 20, which is wider at the top and narrower at the bottom, allows for quick installation and removal of the end cover 20.

[0029] refer to Figure 2 and Figure 6A stepped hole 201 is provided near the wide end of the end cap 20. After the end cap 20 is assembled with the assembly end 103, the bottom end of the stepped hole 201 contacts the top end of the assembly end 103.

[0030] In the above scheme, the purpose of the stepped hole 201 is to allow the end cap 20 to abut against the mounting block 40 inside the hollow groove 101. Simultaneously, the cleaning pipe needs to be inserted into the stepped hole 201 to enter the hollow groove 101. During the pipe polishing process, dust and debris will be generated, and this dust and debris will be temporarily stored inside the hollow groove 101. When cleaning the debris inside the hollow groove 101, the end cap 20 needs to be unscrewed, and the barrel 10 inverted to pour out the debris. It should be noted that when cleaning the debris inside the hollow groove 101 by inverting the barrel 10, only most of the debris is poured out, while some debris stuck on the brush head 402 can be ignored.

[0031] Further reference Figures 2-4 The inner wall of the hollow groove 101 is spirally provided with an installation groove 102. The tail end of the installation block 40 matches the installation groove 102. The installation block 40 is spirally arranged and is installed in conjunction with the installation groove 102.

[0032] In the above scheme, the mounting block 40 is spirally pushed into the mounting groove 102 for installation. This design allows for easy disassembly of the mounting block 40. In other words, when the brush head 402 has been used a certain number of times and reaches the wear threshold, the mounting block 40 can be rotated out of the mounting groove 102 for quick replacement.

[0033] Further reference Figure 4 and Figure 5 The cross-section of the mounting block 40 is trapezoidal, and the small end of the trapezoid is spirally provided with a positioning groove 401. The brush head 402 is spirally arranged in the positioning groove 401. The hollow groove 101 is divided into three groups of spaces by a dividing line 403, and the length of the brush head 402 is close to the dividing line 403.

[0034] In the above scheme, since the mounting block 40 is installed inside the spiral mounting groove 102, it means that the positioning groove 401 is set according to the shape of the mounting block 40. Similarly, the brush heads 402 arranged inside the positioning groove 401 are also spirally arranged. Enhanced rotational friction: When the spirally arranged brush heads 402 rotate, the tilt angle of each bristle will form dynamic contact with the outer wall of the pipe, generating stronger friction than a straight arrangement. This design can more efficiently remove rust, oxide layers, or stubborn stains, reducing the number of repeated polishing. Continuous coverage without dead angles: The spiral structure allows the bristles to form a continuous "spiral trajectory" during rotation, covering every detail of the outer wall of the pipe, avoiding local omissions that may occur with a straight arrangement, especially suitable for processing curved or irregular pipe walls; The mounting block 40 has a trapezoidal cross-section. Since the mounting groove 102 is assembled to match the shape of the mounting block 40, it means that the mounting groove 102 also adopts a trapezoidal structure. The purpose of the trapezoidal structure is to ensure that the mounting block 40 spirally entering the mounting groove 102 is not easy to fall off.

[0035] Secondly, in Figure 5 The dividing line 403 is a virtual line and does not exist in the product structure. It is used here to facilitate the description of the length of the brush head 402. The hollow groove 101 is divided into three groups of spaces by the dividing line 403. The length of the brush head 402 is close to the dividing line 403, which means it is close to one-third of the interior of the hollow groove 101. This can provide sufficient contact effect. It should be noted that the actual length of the brush head 402 needs to be determined according to the product being polished. The description of the length in this invention is not limited to the length of approximately one-third.

[0036] In the preferred embodiment, brush head 402 is made of plastic. Brush head 402 is made of metal.

[0037] In this preferred embodiment, the spiral arrangement of the brush head 402 is adapted to different materials: whether the spiral brush head 402 is made of plastic or metal, it is made of a material with elasticity or toughness (such as highly elastic soft rubber or tough plastic, stainless steel wire), which can automatically adjust the contact force according to the pipe material (such as metal, plastic), so as to avoid hard bristles scratching soft pipe walls, or soft bristles being unable to clean hard dirt. The appropriate material of the brush head 402 is rotated according to the grinding needs.

[0038] Example 2: The mounting block 40 is made of ductile metal, and pressure is applied to both ends of the positioning groove 401 to fix the brush head 402. The purpose of the ductile metal is to forge the mounting block 40 into a spiral shape so as to facilitate assembly with the mounting groove 102; the pressure applied to both ends of the positioning groove 401 to fix the brush head 402 is achieved by hydraulic presses on both ends of the positioning groove 401, so that the brush head 402 is fixed inside the positioning groove 401. This method allows for the automated production of mounting blocks 40 with brush heads 402. Ductile metals: aluminum, copper, silver, gold, platinum; the first two materials, aluminum or copper, are preferred; try to use metals with lower prices to reduce the company's production costs.

[0039] Example 3: refer to Figures 1-3 The connecting end 30 is a hexagonal prism, and the connecting end 30 is fixed to the bottom of the barrel body 10 using set screw technology.

[0040] In the above scheme, the hexagonal prism-shaped connecting end 30 can be easily connected to power tools. Standard power tool products all use hexagonal connectors to unify and standardize the process. The set screw is directly embedded into the axial positioning groove or hole of the hexagonal prism through the tail design (such as a flat tail or a pointed tail), forming mechanical interference and completely eliminating axial movement. The set screw is a commonly used processing technology in the market, which will not be described in detail here. Its purpose is to lock the connecting end 30 to the bottom of the barrel 10.

[0041] The specific implementation process of this embodiment is as follows: Before starting the power tool, the pipe to be cleaned needs to be inserted into the hollow groove 101 inside the barrel 10, that is, the outer wall of the pipe contacts the brush head 402. Under the high-speed rotation of the barrel 10, the brush head 402 can quickly polish and clean the outer wall of the pipe. When the brush head 402 has been used a certain number of times and reaches the critical wear value, it is advisable to rotate and remove the mounting block 40 from the mounting groove 102, rotate and open the end cover 20, and then remove and replace the mounting block 40. When it is necessary to clean the debris inside the hollow trough 101, the end cap 20 needs to be unscrewed and the barrel 10 inverted to pour out the debris inside the hollow trough 101. When pouring out the debris, the barrel 10 can be shaken or the barrel 10 can be hit with an external object to improve the debris pouring effect.

The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
