[0002] Sounds that should not exist in a certain environment generally refer to noisy and harsh sounds. From the perspective of environmental protection, any sound that interferes with people's normal rest, study and work, as well as any sound that interferes with the sounds people want to hear, are all considered noise. Noise is a type of sound that causes people to be irritated, or is too loud and harmful to human health. Noise pollution mainly comes from transportation, vehicle horns, industrial noise, construction, social noise such as concert halls, tweeters, morning markets and people talking loudly. As people pay more attention to noise pollution, many mechanical products need to be tested for noise before leaving the factory. Noise testing is usually carried out in a soundproof room, and the staff operates in the soundproof cabin inside it to avoid the noise during the test from causing harm to the staff;

[0022] Furthermore, the inner wall of one end of the annular mounting block 7 is connected to the other end of the mounting hole 5, and a hexagonal groove 71 is provided on the upper surface of the annular mounting block 7. The inner wall of the hexagonal groove 71 is slidably connected with a guide slider 72 distributed in a ring array. The oxygen content sensor 4 plays a role in real-time monitoring of the oxygen content inside the soundproof cabin body 1, and the ventilation fan 6 plays a role in circulating the outside air with the soundproof cabin body 1.

[0023] Furthermore, a moving block 73 is fixedly connected to the upper surface of the guide slider 72, a driving rod 74 is fixedly connected to the upper surface of the moving block 73, and a triangular sealing block 75 is fixedly connected to one side surface of the moving block 73. The guide slider 72 cooperates with the moving block 73 to drive the triangular sealing block 75 to guide and move.

[0024] Furthermore, one side surface of two adjacent triangular sealing blocks 75 contacts each other, the lower surfaces of the plurality of triangular sealing blocks 75 contact the upper surface of the annular mounting block 7, an annular limiting groove 76 is provided on the outer surface of the annular mounting block 7, and the plurality of triangular sealing blocks 75 contact and seal with each other, thereby achieving the effect of isolating noise when closed.

[0025] Furthermore, the inner wall of the annular limit groove 76 is slidably connected with an arc-shaped limit slider 77 distributed in an annular array, and the outer surfaces of multiple arc-shaped limit sliders 77 are fixedly connected with a rotating ring 78. The inner surface of the rotating ring 78 contacts the outer surface of the annular mounting block 7. Through the use of the annular limit groove 76 and the arc-shaped limit slider 77, the rotating ring 78 is coordinated to rotate stably.

[0026] Furthermore, an outer gear ring 79 is fixedly sleeved on the outer surface of the rotating ring 78, and an annular sealing plate 710 is fixedly connected to the upper surface of the rotating ring 78. The lower surface of the annular sealing plate 710 contacts the upper surfaces of multiple triangular sealing blocks 75. The upper surface of the annular sealing plate 710 is provided with movable grooves 711 distributed in a circular array. The annular sealing plate 710 cooperates with the triangular sealing blocks 75 to perform sealing when closed, and cooperates with the triangular sealing blocks 75 to allow air to circulate when opened.

[0027] Furthermore, the inner wall of the movable groove 711 is slidably connected to the outer surface of the driving rod 74, and a servo electric cylinder 712 is fixedly installed on the upper surface of the sound insulation cabin body 1. One end of the piston rod of the servo electric cylinder 712 is fixedly connected to a rack 713, and the tooth surface of the rack 713 is meshed with the tooth surface of the outer gear ring 79. The telescopic movement of the piston rod of the servo electric cylinder 712 plays the role of driving the meshing outer gear ring 79 to rotate through the rack 713.

[0028] Through the closing device, the mounting hole 5 is closed and sealed when the ventilation fan 6 is not in use, thereby preventing noise from penetrating into the soundproof cabin body 1, improving the working environment of the staff, and solving the problem that during noise detection, noise may penetrate into the interior of the soundproof cabin body 1 through the ventilation component, causing harm to the staff's body.

[0029] Working principle: Step 1, when the ventilation fan is not working, multiple triangular sealing blocks 75 contact and seal each other, thereby preventing noise from penetrating into the interior of the soundproof cabin body 1 through the mounting hole 5. When the operator manually turns on the ventilation fan 6 or the oxygen content sensor 4 detects that the oxygen content inside the soundproof cabin body 1 is lower than the preset value, the piston rod of the servo electric cylinder 712 will be started to extend. The extension of the piston rod of the servo electric cylinder 712 drives the meshing outer gear ring 79 to rotate through the rack 713. The outer gear ring 79 drives the rotating ring 78 to rotate stably through the cooperation of the annular limiting slide groove 76 and the arc-shaped limiting slide block 77;

[0030] Step 2: The rotation of the rotating ring 78 drives the annular sealing plate 710 to rotate. The rotation of the annular sealing plate 710 drives the driving rod 74 to move through the cooperation of the movable groove 711. The movement of the driving rod 74 drives the moving block 73 to move through the cooperation of the hexagonal slide groove 71 and the guide slider 72, so that the multiple triangular sealing blocks 75 are moved and opened. At this time, the mounting hole 5 is connected with the inside of the annular mounting block 7 and the inside of the annular sealing plate 710, and air circulation is achieved through the operation of the ventilation fan 6.

[0031] Step three, when noise detection is required, the ventilation fan 6 is turned off and the piston rod of the servo electric cylinder 712 is started to retract, thereby driving the meshing outer gear ring 79 to rotate in the opposite direction through the rack 713. The outer gear ring 79 drives the annular sealing plate 710 to rotate in the opposite direction through the rotating ring 78. The rotation of the annular sealing plate 710 cooperates with the movable groove 711 and the driving rod 74, so that the multiple triangular sealing blocks 75 move in the opposite direction and close, thereby achieving sealing again to prevent noise from penetrating.

[0032] 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.
