Description

Technical Field

[0001] This utility model relates to the field of PPR pipe technology, and in particular to a PPR pipe that is easy to clean internally. Background Technology

[0002] With the development of the pipe industry, various pipe materials have emerged on the market, such as metal, PP, and PPR. PPR, short for Type III polypropylene, also known as random copolymer polypropylene pipe, is welded using a heat fusion method with specialized welding and cutting tools, offering high plasticity. It is also economical. With an added insulation layer, its thermal insulation performance is better, and the pipe wall is smooth (excluding threaded joints). It is generally used for embedded in walls or pre-buried in deep wells. PPR pipes are moderately priced, have stable performance, are heat-resistant and insulating, corrosion-resistant, have a smooth inner wall that prevents scaling, and provide a safe and reliable piping system that does not leak, with a service life of up to 50 years. However, it requires high-level construction techniques, necessitating specialized tools and professional personnel to ensure system safety.

[0003] Currently, after PPR pipes are used, certain impurities tend to adhere to the inner wall of the pipe. When cleaning is required, the pipe must first be disassembled for cleaning, or additional cleaning structures may be added for cleaning.

[0004] The above-mentioned disassembly method for cleaning is quite inconvenient, requiring not only disassembly but also subsequent installation. Existing cleaning structures require significant modifications to the pipe itself, greatly increasing costs. Therefore, we propose a PPR pipe that is easier to clean internally. Utility Model Content

[0005] The purpose of this utility model is to provide a PPR pipe that is easy to clean internally. By setting up a cleaning mechanism, the external adsorption component can be used to drive the internal adsorption component to move, thereby driving the cleaning component to move. The cleaning component can then clean the inner wall of the PPR pipe. Later, the cleaning component can be removed and cleaned by the cooperation of the internal adsorption component and the elastic component.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PPR pipe with an easily cleanable interior, comprising a PPR pipe, wherein a cleaning mechanism is provided on the PPR pipe, the cleaning mechanism comprising:

[0007] A cleaning component is movably disposed inside the PPR pipe and is used to clean the inside of the PPR pipe.

[0008] A fixing frame is fixedly connected to one side of the cleaning component. Both sides of the fixing frame are provided with built-in adsorption components. The outer surface of the PPR pipe is fitted with an external adsorption component, and the external adsorption component and the built-in adsorption component adsorb each other.

[0009] An elastic component is disposed between the built-in adsorption component and the fixing frame, and the elastic component is used to push the built-in adsorption component.

[0010] A limiting ring is fixedly connected to the end of the PPR pipe and is used to limit the position of the built-in adsorption component.

[0011] Preferably, the cleaning assembly comprises a fixed sleeve and a cleaning sponge fixedly connected to the outer surface of the fixed sleeve, and both ends of the cleaning sponge are provided with inclined annular surfaces.

[0012] Preferably, the built-in adsorption components include an arc-shaped block, a built-in arc-shaped magnet fixedly connected to the outer surface of the arc-shaped block, a connecting block fixedly connected to the inner side of the arc-shaped block, and a toggle block fixedly connected to one end of the connecting block, and the two built-in adsorption components are arranged symmetrically.

[0013] Preferably, the external adsorption component includes an outer ring, an arc-shaped pad fixedly connected to both sides inside the outer ring, and an external arc-shaped magnet fixedly connected to the inner side of the arc-shaped pad.

[0014] Preferably, the elastic component includes a movable rod fixedly connected to the middle of the arc-shaped block, a limiting circular block fixedly connected to one end of the movable rod passing through the fixed frame, and a pushing spring sleeved on the outer surface of the movable rod.

[0015] Preferably, each of the external arc-shaped magnets corresponds to the corresponding internal arc-shaped magnet distribution, and the external arc-shaped magnets and the corresponding internal arc-shaped magnets attract each other.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] By moving the external adsorption component along the PPR pipe, the mutual adsorption between the external and internal adsorption components causes the internal adsorption component to move, which in turn moves the cleaning component along the inside of the PPR pipe. This moving cleaning component cleans the inner wall of the PPR pipe. After cleaning, the external adsorption component is moved to the limiting ring, where the limiting ring and the internal adsorption component are positioned to withstand the impact of the fluid. This design not only cleans the inner wall of the PPR pipe but also requires no major modifications to the PPR pipe itself, reducing costs. Attached Figure Description

[0022] 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.

[0023] This utility model provides, for example Figure 1-3The diagram illustrates a PPR pipe designed for easy internal cleaning, comprising a PPR pipe 1 with a cleaning mechanism. The cleaning mechanism includes: a cleaning component 2, movably disposed inside the PPR pipe 1 and used for cleaning the interior of the PPR pipe 1; a fixing frame 3, fixedly connected to one side of the cleaning component 2, with built-in adsorption components 4 on both sides of the fixing frame 3; an external adsorption component 6 fitted onto the outer surface of the PPR pipe 1, with the external adsorption component 6 adsorbing against the built-in adsorption component 4; an elastic component 5, disposed between the built-in adsorption component 4 and the fixing frame 3, used to push the built-in adsorption component 4; and a limiting ring 7, fixedly connected to one end of the PPR pipe 1. The external adsorption component 6 is positioned along the PPR pipe 1, and the limiting ring 7 is used to limit the internal adsorption component 4. By moving the external adsorption component 6 along the PPR pipe 1, the mutual adsorption between the external adsorption component 6 and the internal adsorption component 4 causes the external adsorption component 6 to move, thereby causing the cleaning component 2 to move along the inside of the PPR pipe 1. In this way, the moving cleaning component 2 is used to clean the inner wall surface of the PPR pipe 1. After cleaning, by moving the external adsorption component 6, the internal adsorption component 4 is moved to the limiting ring 7, which can limit the internal adsorption component 4 and withstand the impact of the fluid. This design can not only clean the inner wall surface of the PPR pipe 1, but also does not require major modifications to the PPR pipe 1 itself, thus reducing costs.

[0024] It should be further explained that the cleaning component 2 consists of a fixed sleeve 201 and a cleaning sponge 202 fixedly connected to the outer surface of the fixed sleeve 201, and both ends of the cleaning sponge 202 are provided with inclined annular surfaces; the fixed sleeve 201 is moved by the built-in adsorption component 4, so that the cleaning sponge 202 is used to clean the inner wall surface of the PPR pipe 1. The cleaning sponge 202 is in full contact with the PPR pipe 1, which can improve the cleaning effect.

[0025] It should be noted that the built-in adsorption component 4 includes an arc-shaped block 401, a built-in arc-shaped magnet 402 fixedly connected to the outer surface of the arc-shaped block 401, a connecting block 403 fixedly connected to the inner side of the arc-shaped block 401, and a toggle block 404 fixedly connected to one end of the connecting block 403. The two built-in adsorption components 4 are arranged symmetrically. By pressing the toggle block 404, the arc-shaped block 401 squeezes the elastic component 5, thereby causing the arc-shaped block 401 to drive the built-in arc-shaped magnet 402 to move until the built-in arc-shaped magnet 402 is no longer limited by the limiting ring 7. At this time, the built-in adsorption component 4 and its cleaning component 2 can be taken out together, so as to facilitate the cleaning of the cleaning component 2 and maintain the good cleaning ability of the cleaning component 2.

[0026] Furthermore, the external adsorption component 6 includes an outer ring 601, an arc-shaped pad 602 fixedly connected to both sides inside the outer ring 601, and an external arc-shaped magnet 603 fixedly connected to the inner side of the arc-shaped pad 602; each external arc-shaped magnet 603 is distributed in a manner corresponding to the distribution of the corresponding internal arc-shaped magnet 402, and the external arc-shaped magnet 603 and the corresponding internal arc-shaped magnet 402 are mutually attracted; by the mutual attraction between the external arc-shaped magnet 603 and the internal arc-shaped magnet 402, it is convenient to move the outer ring 601, thereby using the external adsorption component 6 to drive the internal adsorption component 4 to move, thereby driving the cleaning component 2 to move.

[0027] Furthermore, the elastic component 5 includes a movable rod 501 fixedly connected to the middle of the arc-shaped block 401, a limiting circular block 502 fixedly connected to one end of the movable rod 501 passing through the fixed frame 3, and a pushing spring 503 sleeved on the outer surface of the movable rod 501. When the built-in adsorption component 4 is located inside the PPR pipe 1, the pushing spring 503 is in a slightly compressed state, which allows the built-in arc-shaped magnet 402 to fit against the PPR pipe 1, thereby facilitating the external arc-shaped magnet 603 to better attract the built-in arc-shaped magnet 402 and avoid generating large gaps.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
