Description

Technical Field

[0001] This utility model belongs to the field of drainage pipe technology, and in particular relates to a noise-reducing HDPE silent drainage pipe. Background Technology

[0002] HDPE pipe is a type of pipe made of high-density polyethylene. HDPE pipe is a replacement product for traditional steel pipes and polyvinyl chloride drinking water pipes.

[0003] Existing HDPE drainage pipes are often made of a single layer with a simple structure. When water flows inside the pipe, it collides with the pipe wall, generating noise. Furthermore, due to the limited space inside the drainage pipe, there is no structure to slow down the water flow. When the water flow is large, a water seal forms inside the drainage pipe, which not only causes poor water flow but also easily generates water flow noise. To solve the above problems, a noise-reducing HDPE silent drainage pipe is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a noise-reducing HDPE silent drainage pipe to solve the problem that when water flows inside the pipe, it will collide with the pipe wall and generate noise. Also, because the space inside the drainage pipe is limited and there is no water flow slowing structure, when the water flow is large, a water seal will form inside the drainage pipe, which will not only cause water flow obstruction, but also easily generate water flow noise.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a noise-reducing HDPE silent drainage pipe, including a drainage pipe body. The drainage pipe body has an inner cavity, and a reinforcing rib and a sound-absorbing plate are fixedly connected inside the inner cavity. A deceleration plate is fixedly connected inside the drainage pipe body. Several diversion grooves are formed on the upper surface of the deceleration plate. A connecting rod is fixedly connected to the bottom surface of the deceleration plate, and a deceleration block is fixedly connected to the bottom end of the connecting rod.

[0007] Preferably, a damping plate is installed on the peripheral side of the drain pipe body, and sound insulation cotton is installed on the peripheral side of the damping plate.

[0008] Preferably, the sound-absorbing panel has a plurality of sound-absorbing holes on its peripheral side, and the sound-absorbing holes are arranged in a ring array on the peripheral side of the sound-absorbing panel.

[0009] Preferably, the flow divider array is located on the upper surface of the deceleration plate.

[0010] Preferably, the cross-section of the spiral strip is arranged with a downward spiral, and the spiral strips are arranged in a ring array on the circumferential side of the inner wall of the drain pipe body.

[0011] Preferably, the sound-absorbing panel is made of glass fiber, and the upper surface of the deceleration block is arc-shaped.

[0012] Preferably, the damping sheet is bonded and attached to the drain pipe body.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a slowing plate, slowing block, reinforcing ribs, sound-absorbing plate, and spiral strip to divert water through multiple diversion channels. The water flow is reduced, and the water flows through the slowing block to slow down the water flow speed, avoiding excessive noise caused by the impact of the water flow speed on the inner wall of the drain pipe. The spiral structure of the spiral strip can reduce pressure fluctuations in the drain pipe and improve the stability of the drainage system. At the same time, the spiral strip can guide the flow, thereby reducing the noise of the water flow impacting the pipe wall, and can effectively reduce the noise generated by the drain pipe body.

[0015] 2. This utility model incorporates damping sheets and sound insulation cotton. The damping sheets are bonded to the circumferential side of the drain pipe body. The damping sheets have excellent vibration reduction and noise reduction properties, which can effectively reduce the vibration generated by the impact on the inner wall of the drain pipe body. The sound insulation cotton is wrapped around the circumferential side of the damping sheets, which further absorbs noise and further improves the noise reduction capability of the drain pipe body.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a noise-reducing HDPE silent drainage pipe, including a drainage pipe body 1. The drainage pipe body 1 has an inner cavity 9, within which reinforcing ribs 10 and sound-absorbing plates 11 are fixedly connected. A deceleration plate 4 is fixedly connected inside the drainage pipe body 1. Several diversion grooves 5 are formed on the upper surface of the deceleration plate 4. A connecting rod 6 is fixedly connected to the bottom surface of the deceleration plate 4, and a deceleration block 7 is fixedly connected to the bottom end of the connecting rod 6. By setting up the deceleration plate 4, deceleration block 7, reinforcing ribs 10, sound-absorbing plates 11, and spiral strips 8, when water flows through the deceleration plate 4, it is diverted by the multiple diversion grooves 5, reducing the water flow. When the water flows through the deceleration block 7, the space through which the water flows is reduced, thereby slowing down the water flow. The flow rate is controlled to prevent excessively fast water flow from impacting the inner wall of the drain pipe body 1 and generating excessive noise. When the water flow impacts the inner wall of the drain pipe body 1, noise is generated. The noise is absorbed and consumed by the sound-absorbing plate 11 and the sound-absorbing holes 12 to achieve a noise reduction effect. The spiral structure of the spiral strip 8 can reduce the pressure fluctuation inside the drain pipe body 1, preventing water seal damage caused by excessive negative pressure for upper users and excessive positive pressure for lower users, thus improving the stability of the drainage system. At the same time, the spiral strip 8 can also play a guiding role, thereby reducing the noise of water flow impacting the pipe wall and effectively reducing the noise generated by the drain pipe body 1. The reinforcing rib 10 can improve the strength of the drain pipe body 1.

[0026] A damping plate 2 is installed on the circumferential side of the drain pipe body 1, and a sound insulation cotton 3 is installed on the circumferential side of the damping plate 2. By setting the damping plate 2 and the sound insulation cotton 3, the damping plate 2 is bonded to the circumferential side of the drain pipe body 1. The damping plate 2 has excellent vibration reduction and noise reduction properties and can effectively reduce the vibration generated by the impact on the inner wall of the drain pipe body 1. The sound insulation cotton 3 is wrapped around the circumferential side of the damping plate 2 and then tightened and fixed with tape or steel strips to further absorb noise and further improve the noise reduction capability of the drain pipe body 1.

[0027] The sound-absorbing panel 11 has a plurality of sound-absorbing holes 12 on its peripheral side, and the sound-absorbing holes 12 are arranged in a ring on the peripheral side of the sound-absorbing panel 11.

[0028] The flow divider 5 is arranged in a ring on the upper surface of the deceleration plate 4.

[0029] The cross-section of the spiral bar 8 is arranged in a downward spiral, and the spiral bar 8 is arranged in a ring on the circumferential side of the inner wall of the drain pipe body 1.

[0030] The sound-absorbing panel 11 is made of fiberglass, and the upper surface of the deceleration block 7 is curved.

[0031] The damping sheet 2 is bonded and attached to the drain pipe body 1.

[0032] Example:

[0033] like Figures 1-4 As shown, the method of using the noise-reducing HDPE silent drainage pipe of this utility model is as follows: When using this utility model, when the water flows through the deceleration plate 4, it is diverted by multiple diversion channels 5, making the water flow smaller. When the water flows through the deceleration block 7, the space through which the water flows is reduced, thereby slowing down the water flow speed and preventing the water flow speed from impacting the inner wall of the drainage pipe body 1 and generating large noise. When the water flow impacts the inner wall of the drainage pipe body 1, noise is generated. The noise is absorbed and consumed by the sound-absorbing plate 11 and the sound-absorbing holes 12, achieving the noise reduction effect. The spiral structure of the spiral strip 8 can reduce the pressure fluctuation inside the drainage pipe body 1 and prevent negative pressure from affecting upper users. The water seal damage caused by positive pressure for users at higher and lower levels improves the stability of the drainage system. At the same time, the spiral strip 8 can play a guiding role, thereby reducing the noise of water flow impacting the pipe wall and effectively reducing the noise generated by the drainage pipe body 1. The reinforcing rib 10 can improve the strength of the drainage pipe body 1. The damping plate 2 is bonded to the peripheral side of the drainage pipe body 1. The damping plate 2 has excellent vibration reduction and noise reduction properties and can effectively reduce the vibration generated by the impact on the inner wall of the drainage pipe body 1. The sound insulation cotton 3 is wrapped around the peripheral side of the damping plate 2 and then tightened and fixed with tape or steel strips to further absorb noise and further improve the noise reduction capability of the drainage pipe body 1.
