Description

Technical Field

[0001] The present application relates to the technical field of building decoration drainage structures, and specifically to a noise reduction drainage structure for decoration. Background Art

[0002] PVC plastic pipes are widely used in building water supply and drainage projects due to their advantages such as light weight, good hydraulic conditions for conveying fluids, strong wear resistance, not easy to clog, not rust, and low labor intensity for installation. At present, in high-rise residential buildings, the sewer pipes of some bathrooms are set in the corners of the bathrooms. With the increase of floors, the noise generated by the drainage of sewer pipes is getting louder and louder. In daily life, families are often disturbed by the sound of running water, especially at night. The noise generated when water is discharged from high floors seriously affects people's rest. Therefore, the drainage structure with noise reduction function in the prior art is applied. Although it can play a certain role in noise reduction during use, the noise reduction effect is relatively general. There is still a high probability of affecting people's rest in the quiet night, and the practical performance needs to be strengthened.

[0003] As disclosed in Chinese patent announcement No. (CN213394100U), a noise reduction drainage structure for engineering decoration comprises an outer cylinder, a three-way pipe is installed above the pipeline of the outer cylinder, a drainage pipe is arranged between the three-way pipe and the outer cylinder, and the drainage pipe is fixedly connected to the outer cylinder and the three-way pipe through a support rod. The noise reduction drainage structure for engineering decoration cooperates with the outer cylinder, the three-way pipe, the drainage pipe, the support rod, the sound-absorbing cotton, the circular plate, the cover and the noise reduction mechanism. When the drainage pipe is installed and laid, the operator rotates the cover counterclockwise to separate it from the three-way pipe. At this time, the operator connects the suction pipe of the external suction pump to the joint, and then starts the external suction pump to suck out most of the air between the outer cylinder, the three-way pipe and the drainage pipe through the horizontal cylinder, which can reduce the noise conduction efficiency, thereby improving the noise reduction effect of the drainage pipe, and can significantly reduce the probability of night noise affecting people's rest, and the practical performance is improved.

[0004] However, the above-mentioned patent still has the problem of poor noise reduction and sound insulation effect on the drainage pipe. For example, in the above-mentioned patent, sound-absorbing cotton is arranged on the outside of the drainage pipe to reduce the noise conduction efficiency. However, the sound insulation effect of the sound insulation cotton in this method is easily affected by the external environment. For example, moisture, mold, etc. may reduce its sound insulation performance. Moreover, simply setting sound insulation cotton on the outside of the drainage pipe may not completely solve the noise problem generated by the drainage system. Utility Model Content

[0013] Furthermore, a vacuum chamber is provided on a side of the isolation sleeve opposite to the drain pipe and between two adjacent connecting rings.

[0014] By adopting this technical solution, noise propagation can be further isolated and the noise reduction effect can be improved.

[0015] Furthermore, the sound insulation pad sleeve is a polyethylene foam sound insulation pad.

[0016] By adopting this technical solution, it has a good sound insulation effect and helps to reduce the noise level.

[0017] Furthermore, the buffer mechanism includes a buffer spring, an anti-impact plate, a shock-absorbing pad and a drainage block, one end of the buffer spring is fixed to the inner wall of the drain pipe, and the other end of the buffer spring is fixedly connected to the anti-impact plate, the shock-absorbing pad is fixed to the side of the anti-impact plate facing away from the buffer spring, and the drainage block is connected to the inner wall of the drain pipe and is located above the anti-impact plate.

[0018] By adopting this technical solution, the vibration and impact inside the drainage pipe can be reduced, thereby reducing noise generation.

[0019] Furthermore, the number of the buffer springs is not less than two and they are located on the inner wall of the drain pipe.

[0020] By adopting this technical solution, it helps to provide better cushioning effect and reduce vibration transmission and noise generation.

[0021] Furthermore, the anti-impact plate is in an arc shape, and the cross-sectional shape of the drainage block is in a triangle shape.

[0022] By adopting this technical solution, it helps to improve the stability and buffering effect of the structure, thereby further reducing the noise level.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. The noise reduction drainage structure for decoration is equipped with a noise reduction mechanism, which is connected to the outside of the drain pipe through a connecting ring and an isolation sleeve, and a vacuum chamber is provided between them, so as to greatly isolate the sound from being transmitted to the outside, and at the same time isolate the sound insulation pad sleeve on the outside of the sleeve. The vacuum chamber and the sound insulation pad sleeve can be used to perform double noise reduction on the drain pipe, which can effectively isolate and absorb the noise generated by the movement of water flow in the drainage pipe, and reduce the possibility of its transmission to the surrounding environment.

[0025] 2. The noise reduction drainage structure for decoration is equipped with a buffer mechanism. The function of the buffer mechanism is to reduce the impact and vibration caused by the water flow movement inside the drainage pipe on the drainage pipe itself, and to reduce the force of the impact transmitted to the inner wall of the drainage pipe.

It can reduce the vibration and noise generated during the operation of the drainage pipe and improve the comfort and stability of the drainage system. BRIEF DESCRIPTION OF THE DRAWINGS
