An object of the utility model is to provide a remove rain-proof device of making an uproar of falling in diesel generating set machine case air inlet outside, guarantee to remove high-efficient operation in adverse circumstances such as rainwater.
In order to achieve the purpose of the utility model, the utility model discloses a rain-proof noise reduction device for the air inlet of the case of the diesel generating set, which comprises protective covers arranged at the two sides of the case of the generating set and positioned at the outer side of the air inlet, wherein the four sides of the protective covers are provided with flange structures fixed with the case; a plurality of rain-proof noise reduction components are arranged on the inner side of the protective cover corresponding to the position of the air inlet on the case; grid-shaped air inlet hole groups arranged in an array are arranged on the panel of the protective cover and between adjacent rainproof and noise-reducing components; the rain-proof noise reduction assembly comprises a baffle fixed with the inner side of the protective cover panel and sponge arranged on the baffle, one end of the baffle is fixed with the inner side of the protective cover panel, and the other end of the baffle downwards forms an angle with the protective cover panel.
Preferably, the included angle between the baffle and the protective cover panel is 45 +/-5 degrees.
Preferably, the corner of the box body on the outer side of the lower part of the protective cover is a downward oblique angle, and a plurality of water leakage holes are formed in the edge of the outer side of the lower part.
Preferably, a rubber sealing ring is arranged between the flange and the case.
Preferably, the baffle is detachably fixed with the inner wall of the protective cover.
The beneficial effects of the utility model are that, the rain-proof device of making an uproar that falls in diesel generating set machine case air intake outside, set up the waterproof safety cover of making an uproar that falls in the generating set air intake outside, be equipped with baffle and amortization sponge in, can effectively change quick-witted case air inlet direction, show the rainwater that the inside negative pressure of reduction diesel generating set during operation caused and the suction of dust, improve air cleaner's life, reduce the noise of generator, guarantee the high-efficient operation of mobile generator group in adverse circumstances such as rainwater.
