Description

Technical Field

[0001] The invention relates to the technical field of clean room noise reduction, and in particular to a clean room technical interlayer with good noise reduction effect. Background Art

[0002] A clean room is a room that meets certain standards for cleanliness. For example, most factory clean rooms have certain requirements for solid particles, while clean rooms in hospitals also require more indicators such as bacterial concentration, air humidity, and noise. In an operating room, it is necessary to make incisions on the patient's internal organs or a certain part of the body for treatment, so there are high requirements for bacterial concentration. At the same time, the surgeon needs a very quiet environment, so the noise in the operating room must also be reduced to below the national standard. Therefore, the operating room is also a type of clean room.

[0003] The technical mezzanine of the clean room refers to the device set up to achieve various indicators of the clean room. A lot of equipment is needed in the operating room, such as oxygen supply equipment, ECG monitoring equipment, etc. However, in order to reduce the noise index in the operating room, the equipment needed in the operating room is placed in the equipment room next door, and the technical mezzanine is set between the equipment room and the operating room. The output pipes of the equipment in the equipment room pass through the technical mezzanine, and the display panel used to monitor the clean indicators in the operating room and the operation buttons of the equipment in the equipment room are all installed on the technical mezzanine. Since the output pipes and operation buttons of the equipment need to be installed on the technical mezzanine, the original seal of the operating room is damaged. The vibration of the equipment in the equipment room and the vibration of the pipes during work will affect the increase of noise in the operating room. Therefore, the technical mezzanine needs further noise reduction treatment. Summary of the invention

By arranging a cavity in the first sound insulation cotton layer, the sound attenuation effect can be improved and the overall sound insulation effect can be enhanced.

The display screen or the operation button can be installed on the shell. The third screw is rotated, and the cable is fixed in the second sleeve by squeezing the second clamping plate through the third screw. This can avoid the shaking of the cable, improve the stability of the cable, and reduce the vibration and noise. The first screw is rotated, and the first screw pushes the second airbag through the second mounting plate. The cable is clamped by the first airbag and the second airbag. This can eliminate the vibration on the cable. The second screw is rotated, and the second screw drives the first clamping plate to clamp on the cable. Since the first sleeve is connected by a spring, the first sleeve has good shock absorption. The vibration of the cable can be reduced by the spring to avoid the vibration and sound from propagating into the operating room. The noise reduction effect is very good.

[0032] Working principle: In the present invention, by arranging a first sound insulation cotton layer 2 between the first wall panel 1 and the second wall panel 3, and arranging a second sound insulation cotton 4 between the second wall panel 3 and the third wall panel 5, the sound insulation effect can be increased while ensuring the strength of the wall surface. By arranging a cavity 9 in the first sound insulation cotton layer 2, the sound attenuation effect can be improved and the overall sound insulation effect can be enhanced. The set cover plate 10 can reduce the sound transmitted from the first through hole, and the set shell 6 and the third sound insulation cotton layer 14 set inside the shell 6 can reduce the sound transmitted from the second through hole.

[0033] The cable is inserted from the first wiring tube 11, and then passes through the second sleeve 1074, the first airbag 1033 and the second airbag 1034, the first sleeve 1056, the second wiring tube 7, the wiring hole 15 in sequence and connected with the display screen or the operation button.

The third screw 1073 is rotated, and the cable is squeezed by the third screw 1073 to be fixed in the second sleeve 1074 by the second clamping plate 1072, which can avoid the shaking of the cable, improve the stability of the cable, and reduce the vibration noise. The first screw 1035 is rotated. The first screw 1035 pushes the second airbag 1034 through the second mounting plate 1036, and the cable is clamped by the first airbag 1033 and the second airbag 1034. This can eliminate the vibration on the cable. The second screw 1054 is rotated, and the second screw 1054 drives the first clamping plate 1055 to clamp on the cable. Since the first sleeve 1056 is connected by the spring 1053, the first sleeve 1056 has good shock absorption. The vibration of the cable can be weakened by the spring 1053 to prevent the vibration and sound from spreading into the operating room. The noise reduction effect is very good.
