Description

Technical Field

[0001] The utility model relates to the technical field of sewer pipe noise reduction, in particular to a sewer pipe sound insulation sleeve with double noise reduction. Background Art

[0002] High-rise buildings are generally constructed at higher altitudes, and sewer pipes are therefore lengthened accordingly. Sewer pipes in high-rise buildings typically use a vertical pipe design, concentrating the drainage outlets of each household and discharging them through a single vertical pipe. This design allows for a faster water flow rate, and the vertical flow characteristic can easily cause noisy water noise. Pipes used in sewers in high-rise buildings are generally made of rigid materials such as PVC. These materials are relatively rigid, making it easier for water and impact noise to be transmitted. Compared to some sound-insulating materials, rigid PVC pipes perform poorly in terms of sound insulation. The current method for reducing noise in sewer pipes is to coat the pipe surface with sound insulation cotton. A single layer of sound insulation cotton has limited noise reduction effects. Construction involves cutting the sound insulation cotton on-site, then wrapping it around the outside of the sewer pipe, and finally tying it with cable ties. This involves numerous construction steps, and the aesthetics of the wrapped pipe are poor, requiring improvement. Therefore, we propose a sewer pipe sound insulation sleeve with dual noise reduction. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1, as Figure 1-5 As shown, the utility model provides a technical solution: a double noise reduction sewer pipe sound insulation cover, including a semicircular sound insulation cover A1 and a semicircular sound insulation cover B2, the fitting ends of the semicircular sound insulation cover A1 and the semicircular sound insulation cover B2 are both snap-connected with the wedge strip 3, and the inner walls of the semicircular sound insulation cover A1 and the semicircular sound insulation cover B2 are fixedly provided with a polyurethane foam filling bag 4.

[0021] In a specific embodiment of the present invention, the semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2 are both made of XPS extruded board. The XPS extruded board has excellent pressure resistance and impact resistance, as well as excellent thermal insulation. Its closed-cell rate reaches more than 99%, and its sound insulation effect is relatively excellent. The semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2 are vertically provided with a wedge groove at the mating end. After the semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2 are sleeved on the outer circle of the sewer pipe, a wedge strip 3 is vertically installed in the wedge groove. The shape of the wedge strip 3 can limit the lateral separation of the semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2;

[0022] The polyurethane foam filling capsule 4 is composed of a plastic outer package 401 and an internally filled polyurethane foam 402. When the sound insulation sleeve is not in use, the sealing sticker 5 is attached to the opening of the plastic outer package 401. The polyurethane foam 402 is not in contact with the air. The polyurethane foam filling capsule 4 is flattened to the Figure 1 The shape shown makes it convenient for the semicircular sound insulation sleeve to be installed on the outer circle of the sewer pipe. After the semicircular sound insulation sleeve is stably installed on the outer circle of the sewer pipe, the sealing sticker 5 is directly pulled out, and the polyurethane foam expands in volume when it comes into contact with the air, thereby adaptively fitting the gap between the outer circle of the sewer pipe and the two semicircular sound insulation sleeves. The sound insulation sleeve cooperates with the solidified polyurethane foam to achieve a double noise reduction and sound insulation effect.

[0023] In the preferred technical solution, a hole is opened on the surface of the polyurethane foam filling bag 4, and a sealing sticker 5 is adhered to the outer surface of the hole. The sealing sticker 5 is used to seal the hole. After the semicircular sound insulation sleeve is stably installed on the outer circle of the sewer pipe, the sealing sticker 5 is directly pulled out to allow the polyurethane foam to expand in volume when it comes into contact with the air.

[0024] In the preferred technical solution, both vertical walls of the semicircular sound insulation sleeve A1 are provided with a wedge groove A101, and both vertical walls of the semicircular sound insulation sleeve B2 are provided with a wedge groove B201. The horizontal cross-sections of the wedge groove A101 and the wedge groove B201 are both isosceles trapezoids. The wedge strip 3 is composed of two clips, and the horizontal cross-sections of the two clips are both isosceles trapezoids. The narrow sides of the two clips fit together, and the wedge strip 3 and the wedge groove can form a matching relationship. The shape of the wedge strip 3 can limit the semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2 from being separated horizontally.

[0025] In the preferred technical solution, the polyurethane foam filling bag 4 includes a plastic outer packaging 401, the shape of the plastic outer packaging matches the inner wall shape of the semicircular sound insulation sleeve A1 and the semicircular sound insulation sleeve B2. The thickness of the polyurethane foam filling bag 4 is set to 2 cm, which is convenient for the semicircular sound insulation sleeve to be installed on the outer circle of the sewer pipe.

[0026] In summary: the sound insulation sleeve adopts a split type, which makes it easy to install the sound insulation sleeve on the outside of the sewer pipe. The split sound insulation sleeve adopts a wedge-shaped snap connection to simplify the installation steps of the sound insulation sleeve. A polyurethane foam filling bag 4 is set on the inner wall of the sound insulation sleeve. The polyurethane foam filling bag 4 consists of a plastic outer packaging 401 and an internally filled polyurethane foam 402. When the sound insulation sleeve is not in use, the sealing sticker 5 is attached to the opening of the plastic outer packaging 401, and the polyurethane foam 402 is not in contact with the air. The polyurethane foam filling bag 4 is flattened to the shape of Figure 1 The shape shown makes it convenient for the semicircular sound insulation sleeve to be installed on the outer circle of the sewer pipe. After the semicircular sound insulation sleeve is stably installed on the outer circle of the sewer pipe, the sealing sticker 5 is directly pulled out, and the polyurethane foam expands in volume when it comes into contact with the air, thereby adaptively fitting the gap between the outer circle of the sewer pipe and the two semicircular sound insulation sleeves. The sound insulation sleeve cooperates with the solidified polyurethane foam to achieve a double noise reduction and sound insulation effect.
