Description

Technical Field

[0001] This utility model discloses a long-life drainage pipe, belonging to the field of building engineering. Background Technology

[0002] Drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline.

[0003] When drainage pipes in residential buildings are draining water, wastewater falling from high floors often encounters corners in the pipes. Due to the high flow rate of the water, it can cause significant force when it hits the inner wall of the pipe, eventually leading to cracks or even damage to the drainage pipe.

[0004] In response to the above problems, a new improvement plan is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a long-life drainage pipe to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a long-life drainage pipe, comprising a pipe body, the pipe body including a straight section and a bend section, an inner pipe fixedly connected inside the straight section, a groove being provided on the inner pipe, a diverter plate being slidably installed in the groove, the diverter plate dividing the inner pipe into several non-communicating parts, and several deceleration components being installed on the diverter plate along the extension direction of the inner pipe.

[0007] Preferably, the deceleration assembly includes a base, a baffle, a rotating shaft, and a spring. The base is fixedly connected to the diverter plate, the baffle is fixedly connected to the rotating shaft and rotatably connected to the base through the rotating shaft, and both ends of the spring are fixedly connected to the diverter plate and the baffle, respectively.

[0008] Preferably, the baffle is reinforced with a sound-absorbing panel.

[0009] Preferably, the baffle and sound-absorbing plate are provided with a plurality of interconnected drainage holes.

[0010] Preferably, a plurality of spherical protrusions are fixedly provided on the inner wall of the inner tube.

[0011] Preferably, a deceleration assembly is installed on both sides of the flow divider, and there is a height difference between the deceleration assemblies on different sides.

[0012] Preferably, a sponge pad is fixedly connected inside the bend.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up a diversion plate, the water flow through the drain pipe is divided into two streams, reducing the total amount of water in a single stream, thereby reducing the kinetic energy generated when each stream of water impacts the inner wall of the pipe.

[0015] 2. When the water flows down the straight section of the water pipe, it will intermittently pass through the deceleration components. When the water flows down the straight section, it can be approximated as free fall. Its falling speed is mainly increased by the acceleration due to gravity. Multiple deceleration components can decelerate the water flow after it is accelerated by a certain amount, thereby ensuring that the water flow maintains a low flow velocity when it falls to the corner of the water pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] like Figures 1-5 As shown, a long-life drainage pipe includes a pipe body 1, which includes a straight section 2 and a bend section 3. During the discharge process of wastewater through the pipe body 1, the wastewater first falls and accelerates within the straight section 2, then impacts the bend section 3 at a relatively high flow rate, creating a significant force. An inner pipe 4 is fixedly connected within the straight section 2, and a groove is formed on the inner pipe 4. A diverter plate 5 is slidably installed within the groove. During manufacturing, the diverter plate 5 can be inserted into the groove and installed in place before the inner pipe 4 with the diverter plate 5 installed is inserted into the pipe body 1 and fixedly connected thereto. The diverter plate 5 divides the inner pipe 4 into several non-communicating parts. Several deceleration components are installed on the diverter plate 5 along the extension direction of the inner pipe 4. By setting the diverter plate 5, the water flow passing through the water pipe body 1 is divided into two streams, reducing the total amount of water in a single stream. This reduces the kinetic energy generated when each stream of water impacts the inner wall of the water pipe body 1. At the same time, the deceleration components can block the water flow when it accelerates downward, so that the water flow begins to decelerate before it accelerates to a relatively high speed. This ensures that the water flow reaches the bend 3 at a lower speed, thereby reducing the force of the water flow impacting the bend 3.

[0026] like Figure 5 , Figure 6 and Figure 7As shown, the deceleration assembly includes a base 6, a baffle 7, a rotating shaft 8, and a spring 9. The base 6 is fixedly connected to the diverter plate 5, and the baffle 7 is fixedly connected to the rotating shaft 8 and rotatably connected to the base 6 via the rotating shaft 8. The two ends of the spring 9 are fixedly connected to the diverter plate 5 and the baffle 7, respectively. Supported by the spring 9, the baffle 7 maintains a certain angle, ensuring it can effectively block the water flow. When the water flows down, it will first contact the baffle 7. The baffle 7, impacted by the water flow, begins to rotate on the base 6, thus dissipating some of the force. Since multiple sets of deceleration assemblies are arranged along the extension direction of the inner tube 4... Therefore, the water flow is blocked by the baffle 7 before it can be accelerated to a large speed. Moreover, the baffle 7 of this product is composited with a sound-absorbing panel 10. Common materials for the sound-absorbing panel 10 include wood, mineral wool, polyester fiber, etc., which will not be elaborated here. Through the composite sound-absorbing panel 10, the sound of the water flow impacting the surface of the baffle 7 can be effectively absorbed, thus achieving a noise reduction effect. In addition, the baffle 7 and the sound-absorbing panel 10 are provided with several interconnected drainage holes 11. This design allows some of the water flow to flow down along the drainage holes 11 in advance, which slows down the water flow and improves the drainage efficiency.

[0027] For example Figure 3 and Figure 5 As shown, several spherical protrusions 12 are fixedly installed on the inner wall of the inner tube 4. The spherical protrusions 12 can make the water flowing through the inner wall of the inner tube 4 have a certain wall-hanging effect. After the water flows through the wall, its falling speed will also slow down.

[0028] For example Figure 5 As shown, deceleration components are installed on both sides of the diversion plate 5. There is a height difference between the deceleration components on different sides. This design allows the water flowing through the diversion plate 5 to come into contact with the deceleration components at different times, which in turn makes the time it takes for the water to finally reach the bend of the water pipe body 1 different. This ensures that the water flow at the bend is less in a single impact, thus reducing the kinetic energy generated during the impact.

[0029] Finally, a sponge pad 13 is fixedly connected inside the bend 3, which can buffer and absorb the water flow falling at the bend.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
