Abstract

The invention discloses a silencer for a wind-driven water pump, which comprises a body, a silencing cavity, an air inlet and an air outlet, wherein the air inlet is arranged at the bottom end of the body; the air outlet is arranged at the top end of the body; the silencing cavity is arranged on the inner wall of the body and comprises a silencing and noise reducing block and a silencing cover; the silencing and noise reducing block is tightly connected with the inner wall of the body; and the silencing cover is connected with the outer side of the silencing and noise reducing block. According to the silencer for the wind-driven water pump adopting the mode, which is disclosed by the invention, the silencing cavity is additionally arranged on the inner wall of the body and is filled with the silencing and noise reducing block, so that the noise energy can be better reduced, a better noise reducing effect is obtained, and further the work efficiency of the wind-driven water pump is improved.

Description

A kind of silencer that is used for wind-driven water pump
Technical field
The present invention relates to the wind-driven water pump technical field, particularly relate to a kind of silencer that is used for wind-driven water pump.
Background technique
Wind-driven water pump can produce a large amount of noises in the course of the work, has greatly influenced operator's physical and mental health, has caused environmental pollution.
In order to reduce noise pollution, generally noise insulation equipment can be installed on noise source, existing muffling device generally adopts aperture crowd exhausting silencer technology.This type muffling device all can not reach the requirement of domestic and international related standards at the comparatively abominable scene of operating conditions such as mine, the noise elimination weak effect has influenced workmen's physical and mental health, has also influenced the working efficiency of wind-driven water pump simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of silencer that is used for wind-driven water pump, can subdue noise energy well, thereby obtains noise reduction preferably.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of silencer that is used for wind-driven water pump is provided, comprises: body, silencing cavity, intake grill and exhaust outlet; Said intake grill is arranged on the body bottom; Said exhaust outlet is arranged on the body top, and said silencing cavity is arranged on the inner body wall, and said silencing cavity comprises sound-deadening and noise-reducing piece and silencer cover; Said sound-deadening and noise-reducing piece closely is connected with inner body wall, and said silencer cover is connected the sound-deadening and noise-reducing piece outside.
In preferred embodiment of the present invention, said silencing cavity is an open cavity.
In preferred embodiment of the present invention, be interconnected between said intake grill, exhaust outlet and the body.
In preferred embodiment of the present invention, said sound-deadening and noise-reducing piece is an elastomer, and the cross section of said sound-deadening and noise-reducing piece is parallelogram, triangle or trapezoidal.In preferred embodiment of the present invention, said sound-deadening and noise-reducing piece is sound-absorbing sponge or sound-absorbing rubber.
The invention has the beneficial effects as follows: the present invention has increased silencing cavity on inner body wall; And in this silencing cavity, filled the sound-deadening and noise-reducing piece; Can subdue noise energy well, thereby obtain noise reduction preferably, further improve the working efficiency of wind-driven water pump.
Description of drawings
Fig. 1 is the structural representation that the present invention is used for silencer one preferred embodiment of wind-driven water pump;
Fig. 2 is the structural representation of cross section of the sound-deadening and noise-reducing piece of the present invention's silencer of being used for wind-driven water pump;
The mark of each parts is following in the accompanying drawing: 1, body, 2, silencing cavity, 3, intake grill, 4, exhaust outlet, 5, the sound-deadening and noise-reducing piece, 6, silencer cover.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises:
A kind of silencer that is used for wind-driven water pump comprises: body 1, silencing cavity 2, intake grill 3 and exhaust outlet 4.Said intake grill 3 is arranged on body 1 bottom, and said exhaust outlet 4 is arranged on body 1 top.Said silencing cavity 2 is arranged on body 1 inwall, and said silencing cavity 2 comprises sound-deadening and noise-reducing piece 5 and silencer cover 6, and said sound-deadening and noise-reducing piece 5 closely is connected with body 1 inwall, and said silencer cover 6 is connected sound-deadening and noise-reducing piece 5 outsides.
Said silencing cavity 2 is an open cavity, is interconnected between said intake grill 3, exhaust outlet 4 and the body 1, can play good sound deadening, has increased the effect of sound-deadening and noise-reducing greatly.
Said sound-deadening and noise-reducing piece 5 is an elastomer, is sound-absorbing sponge or sound-absorbing rubber, and the cross section of said sound-deadening and noise-reducing piece 5 is parallelogram, triangle or trapezoidal.Sound-deadening and noise-reducing piece 5 is an elastomer, when it contacts with noise source, can play the effect of noise reduction or vibration damping, also is easy to simultaneously install.
The silencing cavity 2 that the noise that the wind-driven water pump working procedure produces gets into this silencer along with air-flow from intake grill 3; Being arranged on silencing cavity 2 inner sound-deadening and noise-reducing pieces 5 starts working; When noise source contacts with it; Absorbed by sound-deadening and noise-reducing piece 5, discharge from exhaust outlet 4 again through the air-flow that sound-deadening and noise-reducing is handled.
Beneficial effect of the present invention is: increased silencing cavity 2 on body 1 inwall, and in this silencing cavity 2, filled sound-deadening and noise-reducing piece 5, can subdue noise energy well, thereby obtained noise reduction preferably, further improved the working efficiency of wind-driven water pump; This sound-deadening and noise-reducing piece 5 is an elastomer, when it contacts with noise source, can play the effect of noise reduction or vibration damping, also is easy to simultaneously install.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
