According to the technical scheme, the rain cap comprises a clamp, supporting arms and a top cover, one side of the clamp is provided with the supporting arm inclined upwards, the upper portion of the first supporting arm is provided with the rotating second supporting arm through a rotating shaft, one end of the second supporting arm is provided with the top cover corresponding to the opening of the exhaust pipeline, and the lower portion of the first supporting arm is provided with an inserting needle positioning piece provided with an inserting needle corresponding to the tail of the second supporting arm. The rain cap is novel and unique in structure, simple, reasonable, convenient to install and use, easy to maintain, and good in effect, and the rain, snow and dust preventing effects are achieved.
Description
Technical field
The utility model relates to a kind of automatic opening-closing rainhat for box unit smoke exhaust port ran-proof and snow-proof and dust.
Background technique
Generator set is as a kind of conventional standby usage power supply, brought a lot of facilities to people's life production, because people are to noise, the environmental problems such as air are more and more paid attention to, generator set is also had higher requirement accordingly, and generally generator set can be selected to be arranged in quiet casing.
While using, can run into sleet dirty environment unavoidably in the wild, these foreign matters enter by smoke pipe and enter generator set, can have a strong impact on the normal work and use life-span of motor.For addressing this problem, Field Force often covered a movably lid in the past, and unit starting can directly be washed out, and had very large potential safety hazard, and compressor emergency shutdown must manually cover, very inconvenient.Also there are some to be directly fixed on smoke pipe, but because design is unreasonable, often occur normally opening and closing, or adjusting angle underaction.Therefore avoid guaranteeing that unit is not subject to foreign matter to enter motor and affect normal operation, becomes those skilled in the art of the present technique's problem demanding prompt solution under sleet dirty environment.
Summary of the invention
For the technical problem of above-mentioned existing existence, the utility model provides a kind of automatic opening-closing rainhat, and in the time of can effectively solving sleety weather and many dust atmospheres, foreign matter enters gas exhaust duct, has the problem of potential safety hazard.
The technological scheme that the utility model solves is, comprise clip, support arm and top cover, one side of clip is equipped with acclivitous the first support arm, the second support arm of rotation is equipped with on the top of the first support arm through rotating shaft, the top cover corresponding with smoke-ejecting pipe oral area is equipped with in one end of the second support arm, contact pin locating piece is arranged at the first support arm bottom, and the contact pin corresponding with the afterbody of the second support arm is housed on contact pin locating piece.
The utility model novel structure is unique, and advantages of simple, has realized ran-proof and snow-proof and dustproof effect, easy for installation, and easy care is easy to use, effective.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Fig. 2 is use phase diagram of the present utility model (when top cover is closed).
Fig. 3 is use phase diagram of the present utility model (when top cover is opened).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
By Fig. 1-3, provided, the utility model comprises clip, support arm and top cover, it is characterized in that, one side of clip 8 is equipped with acclivitous the first support arm 4, the second support arm 1 of rotation is equipped with on the top of the first support arm 4 through rotating shaft 2, the top cover corresponding with smoke-ejecting pipe 9 oral areas 6, the first support arm 4 bottoms are equipped with in one end of the second support arm 1 contact pin locating piece 3, and the contact pin corresponding with the afterbody of the second support arm 15 is housed on contact pin locating piece 3.
For guaranteeing using effect, on described contact pin locating piece 3, there is uniform positioning hole 3a, contact pin 5 is installed in positioning hole 3a; Described positioning hole 3a has uniform 3, by changing the position (being arranged in different positioning holes) of contact pin 5, realizes the switching angle of rainhat and controls, and maximum opening should be less than 90 °, cannot be closed to prevent rainhat from crossing out;
On described clip 8, fastening piece 7 is housed;
Described clip 8 is sleeved on smoke-ejecting pipe 9, and top cover 6 is placed on the smoke outlet of smoke-ejecting pipe 9;
Described top cover adopts 304 stainless steel materials to make;
The second support arm of described rotating shaft both sides, the side amount of stressing at top cover place, much larger than opposite side, can realize like this after top cover is opened and can rely on the gravity of self closed, and better tightness in the time of also can guaranteeing compressor emergency shutdown, has realized ran-proof and snow-proof and dustproof effect.
When the utility model is used, generator set has two states, operation or shutdown.Generator set when operation: under the gas of smoke-ejecting pipe 9 interior High Temperature High Pressure impacts top cover 6 and and the second support arm 1 by light jack-up, jack-up angle can be passed through angle contact pin locating piece 3 choose reasonable, but maximum angle should be less than 90 °, cannot be closed to avoid opening.So, in the situation that guaranteeing that cigarette ash is normal and discharging, cigarette ash is beaten on top cover 6 and is cushioned, and has avoided the cigarette ash diffusion in environment around, and then has avoided cigarette ash to be sucked by unit secondary, has improved air inlet quality; Under the environment of sleet or many dirt, can prevent again that foreign matter from entering.During generator set outage state: top cover 6 can be under self gravitation effect closed and then sealing smoke exhaust port prevent that foreign matter from entering flue, saved artificial sealing.Two states all can effectively avoid foreign matter to enter motor by smoke pipe, has effectively extended the working life of motor.Compared with prior art, that rainhat of the present utility model has concurrently is simple in structure, manufacturing cost is low, beautiful shape, good stability, realized automatic opening-closing, without manual operation, effective ran-proof and snow-proof and dustproof, easy for installation, easy care, easy to use, effective, there are good society and economic benefit.
