Composition contact will form corrosive solution, impact to the safety of equipment.Conventional method is setting rain cover at present, still
Conventional rain cover air outlet is open type, and outer gas stream is possible to pass back into cleaning equipment when not being vented, shadow
The clean-up effect of exhaust gas is rung.
External rainwater can be completely cut off when a kind of simple structure, exhaust are provided therefore and enter exhaust outlet, it can be inverse when without being vented
Only the Rainproof cap for exhaust port of outer gas stream is problem to be solved in the utility model.
Summary of the invention
The purpose of the utility model is to overcome can when in place of the deficiencies in the prior art, providing a kind of simple structure, exhaust
Completely cut off external rainwater and enters exhaust outlet, it can be with the Rainproof cap for exhaust port of check outer gas stream when without being vented.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of Rainproof cap for exhaust port is provided, it is special
Sign is: including outer cover, deflection cone, discharge outlet, the first fixed support, the second fixed support, slide bar, water fender and open circles
Cylinder；The slide bar is supported and fixed in outer cover by the first fixed support with the second fixation；The deflection cone is socketed in the slide bar
On, it can be free to slide along slide bar；The air-flow that the deflection cone can be discharged by exhaust outlet jacks up；At the top of the hollow cylinder
Water fender is arranged in circumference, and the water fender and outer cover lower end constitute collecting tank；The lower end setting of the outer cover is connected to collecting tank
Discharge outlet.
As a preferred embodiment, the deflection cone is made of light material, inner hollow.
As a kind of more preferable scheme, the deflection cone is made of aluminium flake, inner hollow.
As a kind of more preferable scheme, the deflection cone is made of aluminum skeleton outsourcing covering, inner hollow.
As a preferred embodiment, the tapered structure in the top and the bottom of the deflection cone.
As a kind of more preferable scheme, the area of the deflection cone maximum cross section is greater than the cross section face of hollow cylinder
Product.
As a preferred embodiment, the described first fixed support is fixedly supported on horizontal plane with second and angular distribution is presented.
The advantageous effects of the utility model are: can completely cut off external rainwater when providing a kind of simple structure, exhaust
The Rainproof cap for exhaust port that can prevent outer gas stream from flowing back into exhaust outlet, when without being vented.The rain cover can be effectively prevented
Rainwater and outer gas stream enter in exhaust outlet, and structure is simple to operation, and windage is small, and check air-flow, waterproof performance is good, safety
Reliably, it is simple to manufacture, it is low in cost, convenient for extensive production.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model Rainproof cap for exhaust port.
Fig. 2 is the utility model Rainproof cap for exhaust port exterior perspective view.
Fig. 3 is the utility model Rainproof cap for exhaust port perspective interior view.
In figure: 1 being outer cover, 2 be deflection cone, 3 be discharge outlet, 4 be the first fixed support, 5 be the second fixed support, 6 be
Slide bar, 7 be water fender, 8 be hollow cylinder, 9 be collecting tank.
Specific embodiment
The utility model is described in further detail presently in connection with drawings and examples, following embodiment only describes
Property, it is not restrictive, protection scope of this utility model cannot be limited by this.It is not described in detail in the utility model patent
Structure, connection relationship and method, can be understood as common knowledge in the art.
As shown in Figure 1-3, a kind of Rainproof cap for exhaust port, by outer cover 1, deflection cone 2, the fixed support 4 of discharge outlet 3, first, the
Two fixed supports 5, slide bar 6, water fender 7 and hollow cylinder 8 are constituted.Wherein outer cover 1 can prevent rainwater from entering exhaust from side
In mouthful, while keeping whole device compact-sized.Hollow cylinder 8 and the exhaust outlet of equipment export (not shown) phase by conventional method
Connection.
Slide bar 6 is fixed on outer cover 1 by welding or other usual manners by the first fixed support 4 and the second fixed support 5
It is interior.First fixed support 4 and the second fixed support 5 are presented angular distribution in horizontal plane and guarantee fixed stability.Along open circles
Water fender 7 is arranged in 8 top circumferences of cylinder, and water fender 7 and 1 lower end of outer cover constitute collecting tank 9.Lower end setting and the collecting tank 9 of outer cover 1
The discharge outlet 3 of connection.
Deflection cone 2 is socketed on the slide bar 6, can be free to slide along 6 length direction of slide bar on slide bar 6.Deflection cone
2 light weights are made of aluminium sheet or are made of aluminium sheet as skeleton outsourcing covering, and are hollow structure.Covering can be conventional
Heatproof, corrosion-resistant non-metallic fabrics covering (silica gel covering, fluorine glue covering etc.).The gas that deflection cone 2 can be discharged by exhaust outlet
Stream jacks up, and slides up and down on slide bar 6.The top and the bottom of deflection cone 2 are in the face of conical structure and 2 maximum cross section of deflection cone
Product is greater than the cross-sectional area of hollow cylinder 8.The pyramidal structure on top is that rainwater from top falls directly into exhaust outlet in order to prevent
In, conical outer wall of the induction rainwater on 2 top of deflection cone slides, 9 in the collecting tank constituted into outer cover 1 and water fender 7；Lower part
The effect of taper is to play guiding function to the gas of required discharge, allows the flow to smooth discharge, reduces discharge windage.
In practical application, deflection cone 2 is fallen under the effect of gravity when calm, is placed on hollow cylinder 8.Due to deflection cone
The area of 2 maximum cross sections is greater than the cross-sectional area of hollow cylinder 8, therefore deflection cone 2 closes airflow channel, and check is extraneous
Air-flow；So that guiding cone 2 is suspended upwards on slide bar 6 by air-flow flowing pressure when there is wind discharge, opens exhaust passage, make
Air-flow smooth can be discharged.The first fixed support 4 positioned at 6 upper end of slide bar can play the role of deflection cone 2 and limit.And rainwater
It slides along 2 outer wall of deflection cone, is constituted in collecting tank into 1 lower part of outer cover and water fender 7, discharged from discharge outlet 3.
It is above enlightenment according to the desirable embodiment of the utility model, through the above description, related personnel is complete
Various changes and amendments can be carried out in the range of without departing from this item utility model technical idea.This item utility model
Technical scope be not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
