Description
Technical Field
[0001] The utility model relates to the technical field of tunnel fans, in particular to an integrated sound-absorbing shell for tunnel fans. Background Art
[0002] Tunnel fans, also known as tunnel jet air conveyors, tunnel fans, and jet air conveyors, are widely used in tunnels of water conservancy dam projects, highways, railways, subways, etc. Tunnel jet air conveyors include unidirectional jet air conveyors and bidirectional jet air conveyors. Bidirectional jet air conveyors have electronic and mechanical types. The integrated sound-absorbing shell for tunnel fans is a special shell structure specifically applied to tunnel fans. When the air conveyor operates and generates noise, sound waves are transmitted into the integrated sound-absorbing shell. The porous material in the sound-absorbing material layer converts sound energy into heat energy through friction and viscous effects. When sound waves propagate in the pores of the porous material, the vibration friction of air molecules on the pore wall consumes the sound energy, thereby reducing the intensity of the noise. With the development of society, when tunnel fans need to be sound-absorbed, a sound-absorbing shell is used.
[0003] Existing equipment such as CN208311146U, a new type of silencer for tunnel fans, includes a shell assembly and a moving assembly. The shell assembly includes an outer frame, a hook, a support foot, an inner frame, sound insulation cotton, and a resistance type sound-absorbing sheet. The hook is provided at the left end of the front surface of the outer frame, and the hook is fixedly connected to the outer frame. The support foot is provided at the left end of the bottom of the outer frame, and the support foot is welded to the outer frame. The inner frame is provided on the inner side wall of the outer frame, and the inner frame is fixedly connected to the outer frame. At the connection between the inner frame and the outer frame; a telescopic cylinder and wheels are arranged at the bottom of the outer frame. When making a small-range movement during the disassembly process, through the operation of the driving rod, the telescopic rod is pushed to extend, and the wheels connected to the bottom are moved downward until the support foot is separated from the ground. In this way, the silencer can be moved by the rotation of the wheels, thereby reducing the working procedure of the operator and increasing the convenience of the silencer.
[0004] When workers need to sound-absorb the tunnel fan, they install the sound-absorbing shell on the tunnel fan so that the sound-absorbing shell can eliminate the noise generated by the air conveyor. However, after long-term use, the inside of the sound-absorbing shell will accumulate dust, resulting in the need for workers to spend a lot of time disassembling and cleaning the inside of the sound-absorbing shell, thereby increasing the difficulty for workers to maintain the sound-absorbing shell. Summary of the Invention

By setting the disassembly device, it effectively facilitates the worker to clean the inside of the soundproof housing and use the equipment, improves the convenience for the worker to maintain the housing, and reduces the difficulty for the worker to clean the housing.

Through the above settings, when the disassembly device 3 works, it can drive the sound-absorbing component 39 to slide out of the housing 1. The specific working principle will be introduced in detail below and will not be elaborated here.
[0024] Furthermore, two linkage bars 310 are fixedly connected to the surface of the sound-absorbing component 39. The two linkage bars 310 are symmetrically arranged up and down.
