Mute power station shell

Abstract

The invention discloses a mute power station shell comprising a top cap assembly, a frame, door plates, micro-hole mufflers and a filter plate. The top cap assembly is fixed at the top of the frame which is provided with wind inlets and air channels. The air channels are fixed on the door plates which are mounted on the frame. The door plates are combined with the air channels to form an accommodating chamber. The micro-hole mufflers and the filter plate are arranged in the accommodating chamber. The micro-hole mufflers are in rivet connection with the air channel. The inner surfaces of the top cap assembly, the frame, the wind channel and the door plates are all coated with viscoelastic sound insulating material. The surfaces of the walls of the frame are provided with air inlets, the air channels are arranged in the air inlets, and double-layer sound insulating walls are formed by the door plates and the air channels so as to dually eliminate noise. The micro-hole mufflers and the filter plate are arranged in the accommodating chamber to effectively reduce the noise. The viscoelastic sound insulating materials coat and mute cottons are adhered to the inner surfaces of the top cap assembly, the frame, the air channels and the door plates, thus sound wave of the noise is effectively absorbed, and the noise is further reduced.

Description

[0001] technical field [0002] The invention relates to the field of electrical equipment, in particular to a silent power station casing. [0003] Background technique [0004] A power station refers to a device that uses a diesel engine to generate electricity. When a power station in the prior art is working, the operation of the internal diesel engine system will generate a lot of vibration. The vibration will not only easily cause the loss of the diesel engine system, but also generate a lot of noise. Serious noise pollution is formed, seriously affecting the living or working environment. Especially in military industry, in order to ensure concealment, it is necessary to strictly control the noise of the power station, and the power station of the prior art cannot meet the relevant requirements.

Problems solved by technology

[0004] A power station refers to a device that uses a diesel engine to generate electricity. When a power station in the prior art is working, the operation of the internal diesel engine system will generate a lot of vibration. The vibration will not only easily cause the loss of the diesel engine system, but also generate a lot of noise. Form serious noise pollution, seriously affecting the living or working environment

Especially in military industry, in order to ensure concealment, it is necessary to strictly control the noise of the power station, and the power station of the existing technology cannot meet the relevant requirements

[0005] There are also some power stations on the market, which achieve the purpose of shock absorption and noise reduction by adding a buffer and shock absorbing structure. Although it can play a certain role, it will inevitably complicate the structure of the power station and increase the volume of the power station a lot, which cannot meet the requirements of light weight. , portable requirements
