Description
Technical field
The present invention relates to one kind can ventilated type explosion proof window, apply on the forward and backward door of high-tension switch cabinet.
Background technology
In the design of existing high voltage power distributing cabinet cabinet door, in order to reach degree of protection and intensity requirement, former cabinet door design is all adopted
With the measures such as rubber weather strip are installed additional on door, in structure type for the purpose of seal is preferable.Although this structure type
Degree of protection is improved, but very big restriction is received to the ventilation in cabinet and heat dispersion, this also brings much therewith
Cabinet inner high voltage device heating is difficult to distribute in the operation of problem, such as switch cubicle；It is also easy to produce when the environment temperature decreases in cabinet solidifying
Dew；What is more when temperature change is excessive, these condensations, which excessively gather, to be also easy to form water droplet, and these phenomenons easily cause short circuit
Failure, the safe operation to switch cubicle brings very big threat.Therefore, some producers devise vent window on cabinet door for power distributing cabinet,
Preferably ventilation and radiating effect are served, while also reduce the generation of condensation, but this problem of generate new again, that is, works as
When occurring short circuit accident in switch cabinet, firing the high temperature and high pressure gas of generation can be sprayed to outside cabinet by vent window, to O＆M people
The personal safety of member causes very big threat.
The content of the invention
The purpose of the present invention be exactly in order to solve the above problems there is provided one kind can ventilation and heat, can occur accident again
When close in time can ventilated type explosion proof window.
To achieve these goals, the present invention is adopted the following technical scheme that：
One kind can ventilated type explosion proof window, including door body, the door body is provided with ventilation window, it is characterized in that：The door body it is interior
Side ventilation window is provided with dust-proof protection network, and dust-proof protection network top is provided with open-delta perforate hanger, open-delta perforate
The hinged support of hanger is provided with protective plate, and the bottom of the inner side ventilation window of the door body is provided with ㄣ shape brackets, and protective plate is
Lower end leans against the upper end of ㄣ shape brackets when freely hanging state from above.
The present invention is made up of door body, open-delta perforate hanger, dust-proof protection network, protective plate, ㄣ shape brackets, in door body
Provided with ventilation window, it is characterized in that：Has dust-proof protection network on the inside of the door body on ventilation window, the inner side of the door body is divulged information
The top of window is provided with the hanger of open-delta perforate, is provided to protective plate and is hinged left and right ends on hinged support, hanger
The protective plate of support arm is protruded, the bottom of the inner side ventilation window of the door body is provided with ㄣ shape brackets.When protecting plate closing
Whole ventilating opening can be covered, during free state（When opening）Lower end is limited on the inwall of ㄣ shape brackets, makes protective plate
It is limited between ventilating opening and ㄣ shape bracket inwalls and freely swings.
The open-delta perforate hanger is that steel plate is bent into ㄩ shapes, ㄩ shapes two ends respectively on be provided with and be hinged protective plate
Open-delta perforate, the opening of triangle is easy to the installation of protective plate, and the lower prong of triangle has a small plane conduct
Protective plate fulcrum is hinged to be used.
Two ends highlight a support arm respectively to the left and right for the upper end of the protective plate, are used as hanging from above（See Fig. 4）；It is anti-
One, backplate top transverse fold angle, which is suitable for whole part center of gravity, makes its state to be opened in the case where freely hanging state from above（See figure
5）, there is a small bending protective plate both sides and lower end, it is ensured that protective plate can closely coincide when closed be covered in it is dust-proof anti-
On ventilation window on the inside of protecting wire net and door body.
The ㄣ shapes bracket bends for bent plate and formed, and the position-limiting action of the limitation protective plate amplitude of oscillation is served, for effect of divulging information
Fruit is more preferable, provided with air vent.
For ease of installing, open-delta perforate hanger and ㄣ the shape bracket is bolted in door body.
The beneficial effects of the invention are as follows：Under normal condition, protective plate is hinged on open-delta perforate hanger in deadweight
Hang state from above, now ventilation window realizes ventilation and heat in open mode, when an accident occurs, protective plate is firing generation
High temperature and high pressure gas it is affected under be pushed to ventilation window, closely coincide be covered on dust-proof protection network and ventilation window, will
Vent window is closed, so as to prevent operation maintenance personnel to come to harm, and the articulated form of the device is linear contact lay, and swinging axle position is without rubbing
Power and damping are wiped, is quick on the draw, can be acted rapidly when occurring accident.

Embodiment
With reference to above-mentioned accompanying drawing, the present invention is described in detail：Implementation row include：Set in door body 1, the door body
There is ventilation window；Open-delta perforate hanger 2, the open-delta perforate hanger is arranged on the inside of door body on ventilation window
Side, hinged support is provided to protective plate；Dust-proof protection network 3, it is logical that the dust-proof protection network is closely attached to that door body is provided with
On air regulator mouthful, play dust-proof and prevent small worm from entering；Protective plate 4, two ends protrude branch respectively to the left and right for the protective plate upper end
Brace, the hinged support and deadweight provided by open-delta perforate hanger is hung on the inside of ventilation window, protective plate top
There is a transverse fold, its angle is suitable for whole part center of gravity makes it be taken off between ventilation window in the case where freely hanging state from above
From state to be opened is covered on dust-proof protection network and ventilation window when can closely be coincide after failure generation；ㄣ shapes bracket 5,
The ㄣ shapes bracket is installed on the inside of door body below ventilation window, and limitation protective plate freely swings scope.
During using explosion proof window of the invention, under gravity, the support arm protruded by its left and right ends hangs down protective plate 4
On the hinged support for being hung on open-delta perforate hanger, the cross break on protective plate top when hanging from above is curved following to be skewed, prevents
Backplate lower end leans against the upper end of ㄣ shapes bracket 5, is limited to the possibility swung again on the inside of door, with this control protective plate from
By hunting range, now as ventilated type explosion proof window is open mode, the external air of cabinet door can by ventilation window and
Dust-proof protection network 3 is entered in switch cubicle, realizes the ventilation and heat function of switch cubicle and external environment condition（See Fig. 8 normal conditions
When）；When a failure occurs it, protective plate is under the airflow function that high temperature is fired, and moment, which is closely coincide, is covered in the anti-of door body
On dirt protection network and ventilation window, ventilation window and dust-proof protection network 3 are closed（When seeing Fig. 8 malfunctions）, prevent high temperature
High pressure draught is sprayed to outside door body by ventilation window, so as to reach protection purpose, it is to avoid the operation maintenance personnel of switch cubicle comes to harm.
Relied on after trouble shooting from gravity self- recoverage to normal condition.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deform still within protection scope of the present invention that creative work can make.
