Low-noise channel of equipment room

Technical Field

The utility model relates to an environmental noise control technique, concretely relates to equipment room low noise passageway in high noise equipment room.

Background

The noise level of high-noise equipment in equipment rooms of industrial enterprises often exceeds the requirement of 85dB (A) of operating noise limit of a production workshop and exceeds 100dB (A) to form a high-noise workshop, thereby affecting the physical and psychological health of operators.

The independent sound insulation room with a single device is arranged according to the equipment, so that the requirements of sound insulation and noise reduction can be met, however, due to the existence of the device pipeline, an effective sound insulation room is difficult to arrange, especially when a plurality of high-noise devices are arranged in the equipment room, because the closed sound insulation cover leads each device to be required to be provided with a ventilation heat dissipation system, an air inlet system and an air outlet noise elimination system, and an additional ventilation fan is arranged to remove heat generated during the operation of the equipment. On the one hand, this increases the installation costs, and on the other hand, the air flow direction of the ventilation and heat dissipation will be influenced. In the process, the outlet air such as hot air is retained beside the sound insulation cover and enters the air inlet of the sound insulation cover, so that an air inlet and outlet short circuit is formed, the environmental temperature of the equipment is improved, and the normal work of the equipment is possibly influenced. Meanwhile, due to the structure of a plurality of sound insulation covers, the space in a workshop is divided, and therefore the maintenance space of each device is reduced. If the detachable sound insulation cover of the equipment is used, the workload of detachment and reinstallation in the process of major maintenance is increased.

Disclosure of Invention

An object of the utility model is to provide an equipment room low noise passageway can form the low noise passageway of low noise through passageway facade structure, activity ceiling structure in the high noise workshop, and protection equipment maintenance personnel's operational environment satisfies "noise occupational disease harm risk management manual" AQT 4276-2016 requirement.

The utility model provides a technical scheme that its technical problem adopted is: a low-noise channel of an equipment room comprises a channel vertical face structure and a movable ceiling structure, wherein the movable ceiling structure is formed in a herringbone slope type movable ceiling structure by installing two sound insulation and absorption top plates on the tops of the channel vertical face structures on two sides through hinges. When the equipment in the machine room is replaced, the sound insulation and absorption top plates at two sides are put down on the inner side of the vertical surface structure of the channel, and the low-noise channel forms an equipment transportation channel.

The top of the sound insulation and absorption top plate is an oblique angle consistent with the angle of the herringbone slope, the oblique angle surface is provided with an elastic sealing material, and a snap fastener is arranged between the two sides. And a flexible sound insulation plate is arranged at the connecting part between the sound insulation and absorption top plate and the top of the channel vertical surface structure. The transmission of the device noise through the coupling portion can be effectively prevented.

The channel facade structure comprises a sound insulation and absorption plate, a sound insulation observation window, a working access door and a supporting and positioning component. The channel supporting and positioning component is arranged between the outer side of the channel facade structure and the floor of the machine room, so that the channel facade structure is prevented from inclining. The running condition of the equipment can be known through the sound insulation observation window on the low-noise channel, and the equipment enters the equipment area through the working access door when needed. The exposure of equipment maintenance operators to high-noise machine room equipment places is reduced. The machine room equipment maintenance can enter an equipment area through a working access door of the channel vertical surface structure, and when the equipment is overhauled or replaced, the snap fasteners between the tops of the sound insulation and absorption top plates are opened, and the sound insulation and absorption top plates on two sides are put down on the inner side of the channel vertical surface structure. And (4) the equipment is moved into the low-noise channel and conveyed outwards, or the equipment is conveyed into the low-noise channel and is installed in place, and then the herringbone slope type movable ceiling structure is recovered.

The utility model has the advantages that: the closed working channel formed by the channel vertical surface structure and the movable ceiling structure and the sound absorption structures on the inner sides of the channel vertical surface structure and the movable ceiling structure can reduce reverberation noise in the working channel and form a low-noise channel of the equipment room. The noise level of the environment noise in the workplace can meet the standard requirements of lower than 80dB (A) in the noise control design specifications of industrial enterprises GB/T50087-2013 and noise occupational disease hazard risk management guidelines AQT 4276-2016 in a low-noise channel.
