Description

Technical Field

[0001] This utility model relates to the field of galvanized pipe production technology, and in particular to a galvanized pipe water washing device. Background Technology

[0002] Galvanized pipes, due to the excellent corrosion resistance of their zinc coating, are widely used in construction, municipal engineering, agricultural irrigation, fire protection systems, and many other fields. However, during production, transportation, and storage, impurities such as oil, dust, metal shavings, release agent residue, and even minor rust inevitably adhere to the inner and outer surfaces of galvanized pipes. The presence of these impurities not only affects the pipe's appearance but, more importantly, significantly reduces the quality and adhesion of subsequent coating, welding, or hot-dip galvanizing processes. They may even accelerate localized corrosion during use, shortening the pipe's lifespan. Therefore, thorough and effective cleaning of galvanized pipes before they enter subsequent processing or use is a crucial process step.

[0003] Currently, the most common method for cleaning galvanized pipes is still manual high-pressure water guns or brushes. However, this method has the following drawbacks: high labor intensity, low cleaning efficiency, and cumbersome, time-consuming and laborious operation. In addition, it is difficult to clean the inside of some long galvanized pipes, resulting in poor cleaning effect. Utility Model Content

[0004] In view of the above situation and in order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a galvanized pipe water washing device, which effectively solves the problems of existing water washing devices being cumbersome to operate, time-consuming and labor-intensive, and having poor cleaning effect.

The cleaning cylinder 5 is connected to the water supply trough 8 via a connecting pipe 10. The support plate 1 is provided with a water supply pipe 11 that is inserted into the cleaning cylinder 5 and rotatably connected to the cleaning cylinder 5.

[0006] Preferably, the internal meshing gear 2 is rotatably connected to the support plate 1, and a motor 12 is provided at the left end of the support block. A transmission gear 16 that can mesh with the internal meshing gear 2 is coaxially provided on the output shaft of the motor 12.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5 The device includes an L-shaped support plate 1, with an internal meshing gear 2 rotatable along the left and right axes at the left end of the support plate 1, and an arc-shaped block 3 coaxially located at the right end of the internal meshing gear 2. A cleaning cylinder 5 is coaxially fixed to the lower end of the arc-shaped block 3 via a connecting block 4. Multiple evenly distributed bristles 6 are provided on the surface of the cleaning cylinder 5 and the inner surface of the arc-shaped block 3. Multiple internal water spray holes 7 are evenly distributed along the left and right directions at both ends of the cleaning cylinder 5. A water supply trough 8 is provided in the arc-shaped block 3 along the left and right axes. Multiple external water spray holes 9 are evenly distributed along the left and right directions and connected to the water supply trough 8 on the inner side of the arc-shaped block 3. The cleaning cylinder 5 is connected to the water supply trough 8 via a connecting pipe 10. A water supply pipe 11 is provided on the support plate 1, which is inserted into the cleaning cylinder 5 and rotatably connected to the cleaning cylinder 5.

[0023] In order to make the internal meshing gear 2 rotate, the internal meshing gear 2 is rotatably connected to the support plate 1. The left end of the support block is provided with a motor 12, and the output shaft of the motor 12 is coaxially provided with a transmission gear 16 that can mesh with the internal meshing gear 2.

[0024] To prevent leakage, a sealing ring is provided between the water supply pipe 11 and the cleaning cylinder 5.

[0025] To facilitate the collection of cleaned liquid, the support plate 1 is provided with a water collection tank 13 located below the internal meshing gear 2.

[0026] To facilitate the discharge of waste liquid, a water guide pipe 14 is provided at the front end of the water collection tank 13.

[0027] To facilitate the placement of the galvanized pipe, the upper end of the support plate 1 is provided with a placement platform 15 located to the right of the arc-shaped block 3, and the upper surface of the placement platform 15 is an arc-shaped surface coaxial with the cleaning cylinder 5.

[0028] When using this utility model, first connect the water supply pipe 11 to the water supply system. Then, the operator first places the galvanized pipe to be cleaned horizontally on the placement platform 15 on the upper end of the support plate 1. The upper surface of the placement platform 15 is an arc-shaped surface coaxial with the cleaning cylinder 5, which can stably support the pipe body and ensure that the axis of the galvanized pipe is aligned with the axis of the cleaning cylinder 5. After the pipe is properly placed, start the motor 12 on the left end of the support plate 1. The output shaft of the motor 12 drives the transmission gear 16 to rotate. The transmission gear 16 meshes with the internal meshing gear 2, which drives the internal meshing gear 2 and the arc-shaped block 3, connecting block 4 and cleaning cylinder 5, which are coaxially fixed on the right end, to rotate synchronously around the left and right axes.

[0029] The operator then pushes the galvanized pipe or adjusts the device to align the pipe opening with the rotating cleaning cylinder 5, and smoothly rotates and inserts the cleaning cylinder 5 into the galvanized pipe until the predetermined depth. At this time, the bristles 6 densely distributed on the outer surface of the cleaning cylinder 5 begin to rotate and brush the inner wall of the galvanized pipe. At the same time, the bristles 6 on the inner side of the arc block 3 wrap around and brush the outer surface of the galvanized pipe, achieving synchronous mechanical cleaning of the inner and outer walls. Meanwhile, the water supply system is turned on, and water flows into the cleaning cylinder 5 through the water supply pipe 11 on the support plate 1. Part of the water flows directly through the multiple inner water spray holes 7 opened at the front and rear ends of the cleaning cylinder 5 and sprays radially in all directions. The water flow impacts the pipe wall and, together with the rotating bristles 6, washes the inner wall of the galvanized pipe. The other part of the water flow is transported through the connecting pipe 10 to the left and right axial water supply channels 8 opened inside the arc block 3, and then sprayed out through the multiple outer water spray holes 9 evenly distributed on the inner side of the arc block 3. The water flow covers the outer surface of the galvanized pipe and, together with the bristles 6 on the inner side of the arc block 3, washes the outer wall.

[0030] Throughout the cleaning process, the rotating bristles 6 and the continuously sprayed water work together to effectively remove oil, dust, debris, and other impurities adhering to the inner and outer surfaces of the galvanized pipe. The waste liquid generated during cleaning drips downwards under gravity and is collected in the water collection tank 13 located below the internal meshing gear 2. It is then discharged through the water guide pipe 14 at the front end of the water collection tank 13. After the predetermined cleaning time or desired effect is achieved, the water source is first turned off to stop the spraying, and then the motor 12 is turned off to stop its rotation. Finally, the operator removes the galvanized pipe from the placement platform 15 and removes it from the cleaning cylinder 5, thus completing the cleaning operation for one galvanized pipe.

[0031] Compared with the prior art, the beneficial effects of this utility model are: the cleaning cylinder, arc-shaped block, water supply pipe, etc., can realize coaxial rotation cleaning of galvanized pipe, thereby achieving efficient and synchronous automated cleaning of the inner and outer surfaces of galvanized pipe. Compared with traditional manual cleaning, it not only greatly reduces the labor intensity and time consumption of manual operation, but also ensures that the cleaning effect is uniform and thorough, with no dead corners inside and out. This structure is simple, novel in concept, convenient to use, and highly practical.

[0032] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
