Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a PVC drainage pipe with an anti-scaling inner wall. Background Art

[0002] PVC drainage pipe is made of sanitary polyvinyl chloride resin as the main raw material, with appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., and is extruded by plastic extruder and injection molded by injection molding machine. It goes through cooling, curing, shaping, inspection, packaging and other processes. It is now widely used in indoor and outdoor rainwater drainage of buildings and industrial wastewater discharge.

[0003] As shown in the reference case "An Ageing-Resistant and Impact-Resistant PVC Drainage Pipe" with announcement number "CN218468548U", it has good impact resistance and bending resistance. The pipe body is not easily deformed by impact. The pipe body is also resistant to aging and has a long service life, making it suitable for widespread promotion and use.

[0004] However, although the existing drainage pipes are used to strengthen the stability of the pipes through reinforcing ribs and pipe clamps, the water passing through the pipes will generate vibration impact on the inner wall of the pipes and the pipes themselves, which can easily accelerate the damage and aging of the reinforcing ribs and pipe clamps, resulting in a reduction in the service life of the pipes. In addition, the water discharged by the drainage pipes usually carries a large amount of impurities, which can easily clog the inner wall of the drainage pipes, causing the drainage pipes to be easily clogged.

[0005] Therefore, a PVC drainage pipe with anti-scaling inner wall is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a PVC drainage pipe with an anti-scaling inner wall in order to solve the above-mentioned problem, which improves the problem that although the existing drainage pipes are used to strengthen the stability of the pipes by reinforcing ribs and pipe clamps, the water passing through the pipes will generate vibration impact on the inner wall of the pipes and the pipes themselves, which can easily accelerate the damage and aging of the reinforcing ribs and pipe clamps, resulting in a reduced service life of the pipes.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a PVC drainage pipe with anti-scaling inner wall, comprising: a pipe; a reinforcement and protection mechanism, a telescopic reinforcement and protection mechanism for reinforcing the pipe and reducing scale residue, which is arranged on one side of the pipe; wherein the reinforcement and protection mechanism includes a plurality of reinforcement clamps arranged on the surface of the pipe, two adjacent reinforcement clamps are connected to each other, a protection component is provided on one side of the reinforcement clamp, and a buffer component is provided on one side of the pipe, the inner wall of the pipe is a smooth surface, and the inner wall surface of the pipe is provided with a polytetrafluoroethylene coating, when the pipe is in use, the plurality of reinforcement clamps used for fixing and reinforcement can be buffered and protected by the protection component, thereby increasing the service life of the reinforcement clamps, and the buffer component can further absorb the vibration transmitted from the pipe, thereby extending the service life of the pipe and the reinforcement clamps.

[0008] Preferably, the protective component includes two buffer plates fixedly installed on the adjacent sides of the two reinforcement clamps on the same side, two screws are provided on one side of the reinforcement clamp, and the surface of the screw is threadedly connected to two connecting nuts. Multiple reinforcement clamps are grouped in two. When connecting two reinforcement clamps in the same group, a connecting screw can be used to pass through the two reinforcement clamps, and then two connecting nuts and corresponding connecting screws can be used to fix the two reinforcement clamps, which is very convenient. The inner wall of the pipe is a smooth surface, and the inner wall surface of the pipe is provided with a polytetrafluoroethylene coating. The inner wall of the pipe is smooth, the water flow resistance is small, and it is not easy to scale. The polytetrafluoroethylene coating coated on the inner wall has low surface energy characteristics, which reduces the adhesion of dirt and minerals, can ensure smooth water flow in the pipe, reduce energy consumption, and is more suitable for application in water supply and drainage systems.

[0009] Preferably, a gasket is fixedly installed on one side adjacent to the two connecting nuts on the same surface of the screw, and the gasket is arranged in a circular shape. When the connecting nut is threadedly connected to the screw, the gasket can provide additional sealing and buffering effects when the connecting nut is close to the reinforcing clamp, preventing direct metal-to-metal contact, thereby reducing wear and enhancing the stability of the connection.

[0010] Preferably, the buffer assembly includes a plurality of reinforcing ribs fixedly installed inside the pipe, and a plurality of buffer rings are fixedly installed on one side of the plurality of reinforcing ribs. The buffer rings are located on the inner side of the plurality of reinforcing ribs. When the water inside the pipe flows rapidly, the plurality of buffer rings can absorb the flow impact of the water inside the pipe, thereby reducing the direct bearing of the pipe on the impact of the water flow, extending the service life of the pipe, and effectively dispersing the pressure of the water flow on the inner wall of the pipe.

[0011] Preferably, the plurality of buffer rings are located inside the pipe, and the cross-sections of the plurality of buffer rings are set to be elliptical. The elliptical cross-sectional design enables the buffer rings to more effectively disperse and absorb the kinetic energy of the water flowing through the inside of the pipe, so as to more evenly withstand the impact force of the water flow, thereby reducing the pressure and damage to the inner wall of the pipe.

[0012] Preferably, a buffer pad is fixedly installed on the side of the reinforcement clamp close to the pipe, and the buffer pad is arranged in an arc shape. The arc-shaped buffer pad increases the contact area while also enhancing the contact stability between the reinforcement clamp and the pipe, preventing loosening due to vibration or external impact.

[0013] Preferably, a plurality of cavities are provided inside the buffer pad, and a plurality of rubber balls are fixedly installed inside the plurality of cavities. By arranging a plurality of cavities and rubber balls inside the buffer pad, the buffering effect is further enhanced. The rubber balls can move freely in the cavities, providing additional shock-absorbing function, and reducing the stress on the pipeline due to vibration or impact during operation.

[0014] The beneficial effects of the utility model are:

[0015] When the pipeline is in use, the protective component can be used to buffer and protect multiple reinforcement clamps and pipelines. When the water in the pipeline circulates rapidly, the multiple buffer rings can be used to absorb the impact of the water flow in the pipeline, thereby reducing the pipeline's direct resistance to the water flow impact and extending the service life of the pipeline, thereby increasing the service life of the reinforcement clamps and pipelines. The buffer component can further absorb the vibration transmitted by the pipeline, thereby extending the service life of the pipeline and the reinforcement clamps. The inner wall of the pipeline is a smooth surface, and the inner wall surface of the pipeline is provided with a polytetrafluoroethylene coating. The inner wall of the pipeline is smooth, the water flow resistance is small, and it is not easy to scale. The polytetrafluoroethylene coating coated on the inner wall has low surface energy characteristics, which reduces the adhesion of dirt and minerals, can ensure the smooth flow of water in the pipeline, reduce energy consumption, and is more suitable for use in water supply and drainage systems.

[0016] The cushioning effect is further enhanced by setting up multiple cavities and rubber balls inside the cushion. The rubber balls can move freely in the cavities, providing additional shock absorption function and reducing the stress on the pipeline due to vibration or impact during operation.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a PVC drainage pipe with anti-scaling inner wall comprises: a pipe 1; a reinforcement and protection mechanism 2, a telescopic reinforcement and protection mechanism 2 for reinforcing the pipe 1 and reducing scale residue, which is arranged on one side of the pipe 1; wherein the reinforcement and protection mechanism 2 comprises a plurality of reinforcement clamps 21 arranged on the surface of the pipe 1, two adjacent reinforcement clamps 21 are connected to each other, a protection component 22 is arranged on one side of the reinforcement clamp 21, a buffer component 23 is arranged on one side of the pipe 1, the inner wall of the pipe 1 is a smooth surface, and the inner wall surface of the pipe 1 is provided with a polytetrafluoroethylene coating. The pipe 1 is specifically a PVC drainage pipe mainly used in the fields of indoor and outdoor rainwater drainage of buildings and industrial sewage discharge. C drain pipes usually have smooth inner walls, low water flow resistance, and are not prone to scaling. PVC drain pipes used in drainage systems are usually coated with a layer of polytetrafluoroethylene or special silicone resin coating on the inner wall. These coatings have low surface energy characteristics, which reduce the adhesion of dirt and minerals, ensuring smooth water flow in the pipe and reducing energy consumption. They are more suitable for use in water supply and drainage systems. When the pipe 1 is in use, the protective component 22 can be used to buffer and protect the multiple reinforcement clamps 21 used for fixing and reinforcement, thereby increasing the service life of the reinforcement clamps 21. The buffer component 23 can further absorb the vibration transmitted from the pipe 1, thereby extending the service life of the pipe 1 and the reinforcement clamps 21.

[0024] like Figure 2 、 Figure 3 and Figure 4As shown, the protective component 22 includes two buffer plates 221 fixedly installed on the adjacent sides of the two reinforcing clamps 21 on the same side. Two screws 222 are provided on one side of the reinforcing clamp 21. The surface of the screw 222 is threadedly connected to two connecting nuts 223. Multiple reinforcing clamps 21 are grouped into two. When connecting two reinforcing clamps 21 in the same group, the connecting screw 222 can be used to pass through the two reinforcing clamps 21, and then the two connecting nuts 223 and the corresponding connecting screws 222 can be used to fix the two reinforcing clamps 21, which is very convenient. When the two reinforcing clamps 21 are connected, the buffer plate 221 can be used to provide buffer protection between the two reinforcing clamps 21. A gasket 224 is fixedly installed on the adjacent side of the two connecting nuts 223 on the surface of the same screw 222. The gasket 224 is set to a circular shape. When the connecting nut 223 is threadedly connected to the screw 222, the gasket 224 can provide additional sealing and buffering effects when the connecting nut 223 is close to the reinforcing clamp 21, preventing direct metal-to-metal contact, thereby reducing wear and enhancing the stability of the connection.

[0025] like Figure 2 、 Figure 3 and Figure 4 As shown, the buffer assembly 23 includes a plurality of reinforcing ribs 231 fixedly installed inside the pipe 1, and a plurality of buffer rings 232 are fixedly installed on one side of the plurality of reinforcing ribs 231. The buffer rings 232 are located on the inner side of the plurality of reinforcing ribs 231. When the water body inside the pipe 1 circulates rapidly, the plurality of buffer rings 232 can absorb the flow impact of the water body inside the pipe 1, thereby reducing the direct bearing of the pipe 1 on the impact of the water flow, extending the service life of the pipe 1, and effectively dispersing the pressure of the water flow on the inner wall of the pipe 1. The plurality of buffer rings 232 are all located inside the pipe 1, and the cross-sections of the plurality of buffer rings 232 are set to be elliptical. The elliptical cross-sectional design enables the buffer rings 232 to more effectively disperse and absorb the kinetic energy of the water body flowing through the inside of the pipe 1, so as to more evenly withstand the water flow. The impact force of the flow is reduced, thereby reducing the pressure and damage to the inner wall of the pipeline 1. A buffer pad 233 is fixedly installed on the side of the reinforcement clamp 21 close to the pipeline 1. The buffer pad 233 is arranged in an arc shape. The arc-shaped buffer pad 233 increases the contact area while also enhancing the contact stability between the reinforcement clamp 21 and the pipeline 1 to prevent loosening due to vibration or external impact. A plurality of cavities 235 are provided inside the buffer pad 233, and a plurality of rubber balls 236 are fixedly installed inside the plurality of cavities 235. By arranging a plurality of cavities 235 and rubber balls 236 inside the buffer pad 233, the buffering effect is further enhanced. The rubber ball 236 can move freely in the cavity 235, providing additional shock absorbing function, thereby reducing the stress on the pipeline 1 due to vibration or impact during operation.

[0026] When the present invention is in use, the connecting screw 222 can be used to pass through the two reinforcing clamps 21, and then the two connecting nuts 223 and the corresponding connecting screws 222 can be used to fix the two reinforcing clamps 21, which is very convenient. When the two reinforcing clamps 21 are connected, the buffer plate 221 can be used to provide buffer protection between the two reinforcing clamps 21. When the connecting nut 223 is threadedly connected to the screw 222, the gasket 224 can be used to provide additional sealing and buffering when the connecting nut 223 is close to the reinforcing clamp 21, preventing direct metal-to-metal contact, thereby reducing wear and enhancing the stability of the connection. The buffer ring 232 is located on the inner side of the multiple reinforcing ribs 231, and the water inside the pipe 1 is fast. When the water flows at a high speed, the impact of the water flow inside the pipe 1 can be absorbed by multiple buffer rings 232, thereby reducing the direct impact of the water flow on the pipe 1, extending the service life of the pipe 1, and effectively dispersing the pressure of the water flow on the inner wall of the pipe 1. The arc-shaped buffer pad 233 not only increases the contact area, but also enhances the contact stability between the reinforcement clamp 21 and the pipe 1 to prevent loosening due to vibration or external impact. By arranging multiple cavities 235 and rubber balls 236 inside the buffer pad 233, the buffering effect is further enhanced. The rubber ball 236 can move freely in the cavity 235, providing additional shock absorption function, and reducing the stress on the pipe 1 due to vibration or impact during operation.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
