Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly understood, the following technical solutions of the present invention are further described with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 4, a ventilation and noise reduction apparatus of a generator set includes:

the box body 1 is provided with an opening 2; the silencing plate 3 is fixedly arranged in the box body 1 and is arranged close to the opening 2, the box body 1 is divided into a silencing chamber 4 and a ventilation chamber 5 by the silencing plate 3, and the opening 2 is positioned on the silencing chamber 4; and a plurality of ventilation openings 6, wherein the ventilation openings 6 are arranged on the box body 1 and positioned on the ventilation chamber 5. The acoustical panel 3 can carry out the amortization to the noise in the generating set and fall the noise, and vent 6 can reach good ventilation effect for this device can be handled the noise and the heat that generating set produced simultaneously, reaches the purpose of making an uproar of falling ventilates.

The silencing plate 3 is formed by splicing two groups of silencing sheets 31 and is arranged in a V shape, and the open end of the silencing plate 3 is opposite to the opening 2. The contact area is increased, so that the aim of silencing is better fulfilled. Each group of the silencing pieces 31 comprises a first silencing block 311, a second silencing block 312, a mounting frame 313 and a sound insulation medium 314, the mounting frame 313 is fixedly arranged in the box body 1, the first silencing block 311, the sound insulation medium 314 and the second silencing block 312 are sequentially buckled on the hollow part of the mounting frame 313 from outside to inside, and a plurality of through holes are formed in the first silencing block 311 and the second silencing block 312. The sound-insulating medium 314 is fiberglass wool wrapped with fiberglass cloth. First hush piece 311, second hush piece 312 and sound-proof medium 314 constitute and fall the wall of making an uproar, can adsorb a large amount of noises to promoted noise reduction effect, the setting up of through-hole can make the heat distribute vent 6 department from this through-hole, discharges away it through vent 6, reaches the effect of making an uproar and ventilating.

Two relative sides of box body 1 are hollow structure, are located the hollow portion of box body 1 and have set firmly fixed frame 7, have set firmly the aviation baffle 8 of a plurality of linear arrays on the fixed frame 7, and the one end downward sloping of aviation baffle 8. Gaps are formed between the adjacent air deflectors 8, and the gaps are convenient for ventilation and heat dissipation in the box body 1. In order to prevent the noise from directly flowing out of the gap due to the excessively large gap, the length of the air deflector 8 is not necessarily excessively long, and the end portion thereof near the sound-deadening plate 3 cannot exceed the end portion of the first sound-deadening block 311.

Along the direction from the sound attenuation chamber 4 to the ventilation chamber 5, the longitudinal section area of the box body 1 is gradually reduced. So that the top surface of the box body 1 is obliquely arranged, and the ventilation opening 6 is positioned on the top surface of the box body 1, thereby facilitating air exhaust.

Three arc-shaped protective guards 9 are fixedly arranged on the ventilation opening 6. Due to the high temperature at the vent 6, the guard rail 9 plays a role of protection, preventing a person from touching the vent 6.

Uncovered 2 is last to have two connection block 10 of mutual disposition, and connection block 10 is the L type and with box body 1 fixed connection, has three screw hole 11 on the connection block 10. The main box body of the generator set is connected with the box body 1 of the device through the connecting block 10, and the main box body and the box body are locked through screws, so that the main box body and the box body are detachable, and subsequent maintenance work is facilitated.

A smoke outlet 12 is arranged on the box body 1, and a smoke exhaust pipe 13 is connected to the smoke outlet 12; one end of the smoke exhaust pipe 13 is connected with a smoke exhaust area of the generator set, so that tail gas generated by the generator set is exhausted through the smoke exhaust pipe 13. The box body 1 is provided with a detachable slide rail 14, the slide rail 14 is connected with a cleaning brush 15 in a sliding way, a handle 16 is fixedly arranged on the cleaning brush 15, and the smoke outlet 12 is positioned in the moving direction of the cleaning brush 15. Because the tail gas contains a small amount of residues, the residues are accumulated on the smoke exhaust pipe 13 after long-time use and influence the smoothness of the smoke exhaust pipe 13, so that an operator can slide the cleaning brush 15 through the handle 16 at random, the cleaning brush 15 can clean the residues attached to the smoke exhaust pipe 13, and the blockage of the smoke exhaust pipe 13 is prevented.

This embodiment can be to generating set noise reduction and exhaust ventilation, has prolonged generating set's life effectively under the cooperation of acoustical panel 3 and vent 6 is used.
