Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to an anti-clogging drainage pipe for building water supply and drainage. Background Technology

[0002] In the field of building water supply and drainage engineering, drainage pipes, as key components for transporting sewage and wastewater, directly affect the normal operation of the entire drainage system. Currently, drainage pipes on the market commonly face the problem of clogging during actual use. Clogging not only leads to poor drainage but can also cause sewage overflow in severe cases, affecting the building environment and residents' quality of life, while also increasing subsequent maintenance costs.

[0003] Existing drainage pipes suffer from design flaws in their connection structures. The limited contact area at the joints results in weak adhesion, making them prone to loosening and leakage under water flow impact. This reduces the stability of the drainage system and wastes water resources. Furthermore, when pipes become blocked, existing drainage pipes lack convenient and effective inspection and unblocking mechanisms. Maintenance personnel often need to spend considerable time and effort disassembling the pipes for inspection and unblocking, leading to low efficiency. Therefore, this paper proposes a new type of drainage pipe for building water supply and drainage that effectively prevents blockages, enhances connection stability, and facilitates maintenance. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and propose an anti-clogging drainage pipe for building water supply and drainage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clog-resistant drainage pipe for building water supply and drainage, comprising a drainage pipe body, wherein an inner layer pipe with a smooth and corrosion-resistant inner wall is bonded and fixed inside the drainage pipe body to reduce the adhesion of debris; a maintenance pipe head is bonded to an inspection through hole near the outlet end on the outer side of the drainage pipe body for unblocking and observing both ends of the drainage pipe body; two rings of No. 1 strip-shaped short grooves are formed around the outlet end of the inner wall of the drainage pipe body to increase the rotational friction and contact area when the drainage pipe body is spliced; four No. 1 annular grooves are formed between the two rings of No. 1 strip-shaped short grooves on the inner wall of the drainage pipe body to increase the vertical friction and contact area when the drainage pipe body is spliced; two rings of No. 2 strip-shaped short grooves are formed around the inlet end of the drainage pipe body to increase the rotational friction and contact area when the drainage pipe body is spliced; four No. 2 annular grooves are formed between the two rings of No. 2 strip-shaped short grooves on the outer side of the drainage pipe body to increase the vertical friction and contact area when the drainage pipe body is spliced.

[0006] Preferably, the inspection pipe head includes a transparent oblique pipe opening bonded to the inspection through hole of the drain pipe body for viewing the inside of the connection when the drain pipe body is spliced, and also serving as an entry point for unclogging tools; a threaded short sleeve heat-fused to the upper end of the transparent oblique pipe opening; an inclined plug spirally installed in the threaded short sleeve for sealing the transparent oblique pipe opening; and an elliptical rubber ring bonded and fixed to the lower end of the inclined plug to increase the sealing effect of the transparent oblique pipe opening.

[0007] Preferably, the lower end of the transparent oblique tube passes through the inspection hole of the drain pipe body and communicates with the inner tube.

[0008] Preferably, the tilting plug is hollow, and a non-slip groove is formed around the upper end of the tilting plug.

[0009] The beneficial effects of this utility model are as follows: By setting up an inspection pipe head, the blockage at the drain pipe connection can be observed, and unblocking can be assisted. The inside of the drain pipe can be observed through the transparent inclined tube opening. The inclined plug is screwed out from the threaded short sleeve. Tools or chemical agents can be used to clean the pipe connection through the transparent inclined tube opening. The transparent inclined tube opening and the inclined plug are inclined in structure, which makes it easy to insert and operate tools and improves the efficiency of unblocking. The arrangement of the No. 1 strip groove, the No. 1 annular groove, the No. 2 strip groove, and the No. 2 annular groove increases the contact area at the connection point when the main body of the drain pipe is connected, making the adhesion more secure. The No. 1 and No. 2 strip grooves increase rotational friction, enhancing connection stability, while the No. 1 and No. 2 annular grooves increase vertical friction, enhancing connection sealing.

[0012] 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.

[0013] See Figure 1-5 As shown in the figure, this embodiment of an anti-clogging drainage pipe for building water supply and drainage includes a drainage pipe body 1. An inner pipe 2 with a smooth, corrosion-resistant inner wall is bonded and fixed inside the drainage pipe body 1 to reduce debris adhesion. An inspection pipe head 3 is bonded to an inspection through-hole near the outlet end of the drainage pipe body 1 for unclogging and observing both ends of the drainage pipe body 1. Two rings of No. 1 strip-shaped short grooves 4 are formed around the outlet end of the inner wall of the drainage pipe body 1 to increase the rotational friction and contact area during splicing of the drainage pipe body 1. The inner wall of the main body 1 has four annular grooves 5 between two rings of No. 1 strip grooves 4 to increase the vertical friction and contact area when the main body 1 is spliced. The outer side of the main body 1 has two rings of No. 2 strip grooves 6 around the water inlet end to increase the rotational friction and contact area when the main body 1 is spliced. The outer side of the main body 1 has four annular grooves 7 between two rings of No. 2 strip grooves 6 to increase the vertical friction and contact area when the main body 1 is spliced.

[0014] Specifically, the main body 1 of the drain pipe constitutes the main structure of the drain pipe, supporting and protecting the internal components; the inner pipe 2 can be a polyethylene pipe, random copolymer polypropylene pipe, polyvinyl chloride water supply pipe, copper pipe, or thin-walled stainless steel pipe, reducing the probability of debris adhesion and preventing blockage of the inner wall of the water supply pipe; the inspection pipe head 3 allows observation of the blockage at the drain pipe connection and assists in unblocking. The interior of the drain pipe can be observed through the transparent inclined pipe opening 301. The inclined plug 303 is screwed out from the threaded short sleeve 302 via a spiral, allowing tools or chemical agents to be passed through the transparent inclined pipe opening 301. 1. Clean the pipe connection points. The transparent oblique pipe opening 301 and the inclined plug 303 adopt an inclined structure, which facilitates tool insertion and operation and improves the unblocking efficiency. The first strip short groove 4, the first annular groove 5, the second strip short groove 6 and the second annular groove 7 increase the contact area at the connection position when the main body of the drain pipe 1 is connected, so that it is more firmly bonded. The first strip short groove 4 and the second strip short groove 6 increase the rotational friction and enhance the connection stability. The first annular groove 5 and the second annular groove 7 increase the vertical friction and enhance the connection sealing.

[0015] See appendix Figure 1-3 As shown, the inspection pipe head 3 includes a transparent oblique pipe opening 301 bonded to the inspection through hole of the drain pipe body 1, used to inspect the inside of the connection when the drain pipe body 1 is spliced, and also serves as an entry point for unclogging tools; a threaded short sleeve 302 heat-fused to the upper end of the transparent oblique pipe opening 301; an inclined plug 303 spirally installed in the threaded short sleeve 302 for sealing the transparent oblique pipe opening 301; and an elliptical rubber ring 304 bonded and fixed to the lower end of the inclined plug 303 to increase the sealing effect of the transparent oblique pipe opening 301.

[0016] Specifically, the threaded short sleeve 302 provides a threaded interface for installing and removing the tilted plug 303; the tilted plug 303 seals the transparent inclined tube opening 301, and tools or agents can be inserted to unclog the pipe after removal; the elliptical rubber ring 304 enhances the sealing between the tilted plug 303 and the transparent inclined tube opening 301.

[0017] See appendix Figure 1-3 As shown, the lower end of the transparent oblique tube opening 301 passes through the inspection through hole of the drain pipe body 1 and communicates with the inner tube 2.

[0018] Specifically, the transparent inclined tube 301 is connected to the inner tube 2, allowing observation of the blockage inside the tube through the transparent material; See appendix Figure 3 As shown, the tilted plug 303 is hollow, and a ring of anti-slip groove is formed around the upper end of the tilted plug 303.

[0019] Specifically, the anti-slip groove at the upper end of the tilting plug 303 is used to increase friction when manually rotating, making it easier to disassemble.

[0020] In operation, sewage flows into the drain pipe body 1 from the inlet end during daily drainage operations, and is transported to the outlet end through the inner pipe 2. The inner pipe 2 is made of polyethylene, random copolymer polypropylene, polyvinyl chloride, copper, or thin-walled stainless steel. Its smooth surface reduces the adhesion of debris and lowers the risk of blockage. The outer side of the inlet end of the drain pipe body 1 is provided with two rings of No. 2 strip grooves 6 and four No. 2 annular grooves 7. The inner side of the outlet end is provided with two rings of No. 1 strip grooves 4 and four No. 1 annular grooves 5. When connecting pipes, the strip grooves increase the rotational friction, and the annular grooves enhance the vertical sealing, ensuring that the pipe connection is firm and leak-proof. During the blockage observation and unblocking operation, observe whether there is debris accumulation and blockage at the pipe connection through the transparent inclined pipe opening 301 of the inspection pipe head 3. The inclined design of the transparent inclined pipe opening 301 allows direct vision to observe the inside of the pipe without disassembling other parts. When unblocking, hold the anti-slip groove of the inclined plug 303 and manually rotate the inclined plug 303 to unscrew it from the threaded short sleeve 302 using the threaded structure. Insert the unblocking tool or chemical agent into the blockage position of the inner pipe 2 through the inclined channel of the transparent inclined pipe opening 301. The inclined structure shortens the tool insertion path, making it easier to accurately contact the blockage, improving unblocking efficiency, and saving effort. After unblocking, screw the inclined plug 303 back into the threaded short sleeve 302 until the elliptical rubber ring 304 fits tightly against the inner wall of the transparent inclined pipe opening 301 to ensure a leak-proof seal.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
