[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The device forms multiple soundproof rooms that can reflect sound waves by assembling and connecting multiple polyester fiber boards 1, 2, and porous wood boards, so that the sound waves are reflected multiple times in the soundproof rooms and absorbed by multiple soundproof boards, thereby improving the sound insulation effect. At the same time, a stable triangular space structure is formed between the soundproof boards and the inner and outer partition walls, so that the connection between the outer partition wall and the inner partition wall is firmly fixed and convenient for construction;

[0023] 2. This device uses polyester fiber board 1, polyester fiber board 2 and porous wood board to assemble and splice into a soundproof room for efficient sound insulation, abandoning the method of filling multiple layers of sound insulation boards between the inner and outer partition walls, saving the use of sound insulation boards, greatly reducing the weight and volume of the overall device, reducing the workload of installation and transportation, and not causing excessive pressure on the load-bearing wall;

When the outer partition wall is impacted by the outside world or resonates under the influence of noise, the vibration amplitude of the whole device can be reduced through the cooperation of the vibration part, the shock-absorbing ring and the fixed spring, thereby improving the stability of the whole device.

[0026] 5. The vibration part of the device is movably connected to the asbestos soft board through a movable tube and an insertion rod.

At the same time, the structure is reliable, less materials are used, and the difficulty of installation and transportation is reduced. In addition, the setting of the vibration part, the shock-absorbing ring and the fixing spring not only converts part of the sound wave energy into kinetic energy and releases it, but also can reduce the vibration amplitude of the whole device when the outer partition wall is impacted by the outside or resonates under the influence of noise, and improve the stability of the whole device. Moreover, the vibration part vibrates up and down to form a concave cavity on one side and a convex cavity on the other side of the asbestos soft board.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-8 , the present invention provides a technical solution:

[0039] A soundproof partition wall structure, comprising an outer partition wall 1 and an inner partition wall 2, wherein the outer partition wall 1 is connected to the outside, and the inner partition wall 2 is used for internal sound insulation, wherein a plurality of vertically arranged polyester fiber boards 1 3 and horizontally arranged polyester fiber boards 2 4 are fixedly connected between the outer partition wall 1 and the inner partition wall 2, wherein the polyester fiber boards 1 3 and 2 4 are made of soundproof board materials and can absorb noise for sound insulation, and the polyester fiber boards 1 3 and 2 4 divide the area between the outer partition wall 1 and the inner partition wall 2 into a plurality of soundproof rooms 5, and external noise enters the soundproof rooms 5 through the outer partition wall 1;

[0040] The soundproof room 5 is internally connected with a porous wooden board 6 which is tilted and fixed. The porous wooden board 6 is made of a soundproof board material and can absorb noise for sound insulation. The porous wooden board 6 is easy to punch and is symmetrically arranged in adjacent soundproof rooms 5. The porous wooden board 6 divides the soundproof room 5 into two parts. The noise impacts the porous wooden board 6 and is reflected multiple times, so that the noise is absorbed and sound-insulated by multiple soundproof boards to the maximum extent. A triangular space structure is formed between the polyester fiber board 1 3, the polyester fiber board 2 4 and the porous wooden board 6 to ensure the stability of the structure and make the connection between the outer partition wall 1 and the inner partition wall 2 firmly fixed.

[0041] The polyester fiber board 1 3, the polyester fiber board 2 4 and the porous wood board 6 are all provided with a plurality of through holes 7, through which the noise enters the adjacent soundproof room 5, so that the noises in the plurality of soundproof rooms 5 interfere with each other and cancel out part of the noise, thus avoiding the resonance of the noises of the same frequency on the whole device, and ensuring the air circulation of the soundproof rooms 5;

[0042] The porous wooden board 6 is provided with a plurality of through grooves 61, and an asbestos soft board 62 is fixedly connected inside the through grooves 61. The asbestos soft board 62 can form a cavity when squeezed. When the sound wave propagates to the cavity, it is absorbed and weakened by the asbestos soft board 62 after multiple reflections. A movable cylinder 63 is fixedly connected to the side of the asbestos soft board 62 away from the polyester fiber board 4;

[0043] A vibration member 8 is movably connected between the movable cylinder 63 and the polyester fiber board 24. When the noise is reflected multiple times in the soundproof room 5, the sound wave impacts the vibration member 8, converting part of the sound wave energy into kinetic energy, thereby reducing the noise wave energy. An insertion rod 81 is fixedly connected to one end of the vibration member 8 close to the movable cylinder 63, and the insertion rod 81 movably extends into the movable cylinder 63. When the vibration member 8 vibrates up and down, it squeezes the asbestos soft board 62, so that the asbestos soft board 62 forms a concave cavity for absorbing sound waves. A shock-absorbing ring 9 is movably connected to the vibration member 8. The shock-absorbing ring 9 has a buffering effect on the vibration of the vibration member 8 and absorbs part of the kinetic energy. A fixed spring 10 is fixedly connected between adjacent shock-absorbing rings 9. The fixed spring 10 enhances the efficiency of the shock-absorbing ring 9 in absorbing energy. When the outer partition wall 1 is impacted by the outside world or resonates under the influence of noise, the vibration amplitude of the overall device can be reduced through the cooperation of the vibration member 8, the shock-absorbing ring 9 and the fixed spring 10, thereby improving the stability of the overall device.

[0044] One end of the vibration member 8 close to the polyester fiber board 24 is fixedly connected to a connecting rod 11, and one end of the connecting rod 11 away from the vibration member 8 movably extends out of the polyester fiber board 24, and the end of the connecting rod 11 extending out of the polyester fiber board 24 is fixedly connected to the vibration member 8 in the adjacent soundproof room 5, so that the vibration members 8 of adjacent soundproof rooms 5 are connected to each other. The different noise frequencies and propagation directions in different soundproof rooms 5 result in different vibration effects of the vibration members 8 in different soundproof rooms 5. The vibration members 8 in adjacent soundproof rooms 5 influence and weaken each other, thereby reducing the vibration amplitude of the vibration member 8 and improving the stability of the device.

[0045] Specifically, the outer partition wall 1 is provided with a plurality of interference wave holes 101, through which noise waves enter the soundproof room 5. The sound waves can be divided into a weakened area and an enhanced area by the interference effect of the waves. The weakened sound waves are better absorbed by the sound insulation board in the soundproof room 5, and the enhanced sound waves impact on the vibration element 8, which makes it easier to convert the sound wave energy into kinetic energy and be absorbed and weakened. At the same time, the interference wave holes 101 can be used for ventilation between the soundproof room 5 and the outside world.

[0046] Specifically, the connection between the vibration member 8 and the shock-absorbing ring 9 is filled with a shock-absorbing sponge 12, and the connection between the connecting rod 11 and the polyester fiber board 4 is filled with a shock-absorbing sponge 12. The shock-absorbing sponge 12 has a shock-absorbing and buffering effect on the vibration member 8, thereby improving the stability of the device.

[0047] Specifically, the vibration member 8 is composed of two vibration springs connected to each other in an upper and lower manner, and the shock-absorbing ring 9 is movably mounted at the connection between the vibration springs. The shock-absorbing ring 9 buffers the vibration of the vibration member 8 and absorbs part of the kinetic energy. The shock-absorbing rings 9 on adjacent vibration members 8 are fixedly connected by fixing springs 10, and the fixing springs 10 enhance the efficiency of the shock-absorbing ring 9 in absorbing energy.

[0048] A construction process of a sound insulation partition wall structure is used for the above-mentioned sound insulation partition wall structure, and the construction process is as follows:

[0049] a: The polyester fiber board 1 3 is fixedly connected vertically to the inner wall of the outer partition wall 1, and the polyester fiber board 2 4 is fixedly connected horizontally to the inner wall of the outer partition wall 1, so that a plurality of soundproof rooms 5 are formed between the polyester fiber board 1 3 and the polyester fiber board 2 4;

[0050] b: The porous wooden board 6 is fixedly connected in an inclined manner in the soundproof room 5, the two side walls of the porous wooden board 6 are fixedly connected to the polyester fiber board 3, and one side wall of the porous wooden board 6 is fixedly connected to the inner wall of the outer partition wall 1;

[0051] c: Move the insertion rod 81 of the vibration member 8 into the movable cylinder 63, and fix the vibration member 8 in the adjacent soundproof room 5 with the connecting rod 11, movably sleeve the shock absorbing ring 9 on the vibration member 8, and fix the adjacent shock absorbing rings 9 with the fixing spring 10;

[0052] d: The polyester fiber board 1 3 , the polyester fiber board 2 4 and the porous wooden board 6 are fixedly connected to the inner partition wall 2 away from the side wall of the outer partition wall 1 .

[0053] Working principle: external noise enters the soundproof room 5 through the outer partition wall 1, and the noise impacts the porous wooden board 6 for multiple reflections, and the noise enters the adjacent soundproof room 5 through the through hole 7, so that the noises in multiple soundproof rooms 5 interfere with each other and cancel out part of the noise, avoiding the resonance of the noise of the same frequency on the overall device. When the noise is reflected multiple times in the soundproof room 5, the sound wave impacts the vibration member 8, converting part of the sound wave energy into kinetic energy, reducing the noise wave energy, and the shock-absorbing ring 9 buffers the vibration of the vibration member 8 and absorbs part of the kinetic energy, and adjacent shock-absorbing rings 9 are fixedly connected with fixed springs 10, which enhance the efficiency of the shock-absorbing ring 9 in absorbing energy;

[0054] When the vibration member 8 vibrates up and down, it squeezes the asbestos soft board 62, so that the asbestos soft board 62 forms a cavity for absorbing sound waves. When the sound waves propagate to the cavity, they are absorbed and weakened by the asbestos soft board 62 after multiple reflections, thereby further improving the sound insulation effect.

[0055] When the outer partition wall 1 is impacted by the outside world or resonates under the influence of noise, the vibration amplitude of the entire device is reduced through the cooperation of the vibration member 8, the shock absorbing ring 9 and the fixing spring 10, thereby improving the stability of the entire device.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
