Description
Technical field
The utility model is related to the protective plate of venting of dust explosion.
Background technology
With people's security concept more and more higher, increasing people recognizes to pacify on the building with explosion danger
Fill the importance of explosion venting device.Wherein, roofing is used as the important part of building, necessary installation explosion venting device.It is existing
Some explosion venting devices are typically all disposable, as long as by blast impulse, will thoroughly damage.Explosive force it is smaller but frequency
In the case of hair, it can greatly increase material cost and cost of labor.
The content of the invention
The purpose of this utility model is to provide a kind of protective plate of roofing explosion venting device, can resist power less quick-fried
It is fried, and reduce damaged condition.
Realizing the technical scheme of above-mentioned purpose is：
A kind of protective plate of roofing explosion venting device, including steelframe and nine cell boards, wherein,
The steelframe is welded by the equidistant intertexture anyhow of six roots of sensation steel bar, and the steelframe includes the rectangle of nine arrays
Frame；
One cell board is set in each rectangle frame of the steelframe；
Each cell board includes framework, venting of dust explosion flaggy, buffering flaggy, waterproof lamellar, multiple stage clips, the guard of rectangle
With venting of dust explosion bolt, wherein,
One end of the framework is articulated with the side of the rectangle frame, and the other end is fixed on described by the venting of dust explosion bolt
The opposite side of rectangle frame；
The bottom of the framework is extended with four horizontal raised lines；
The buffer board is placed in the framework, is supported by the horizontal raised line；
The waterproof lamellar is fixed on the top of the framework；
The guard is fixed on the top of the framework, and positioned at the top of the waterproof lamellar；
The venting of dust explosion flaggy is fixed in the framework, and is close to the bottom surface of the waterproof lamellar；
The top of each stage clip is fixedly connected with the venting of dust explosion flaggy, and bottom is fixedly connected with the buffering flaggy.
In the protective plate of above-mentioned roofing explosion venting device, it is provided between four sides of the framework and the rectangle frame
Sealing strip.
The beneficial effects of the utility model are：The utility model is designed by the rectangle frame of array, shares impact, is led to simultaneously
Excessive flaggy and stage clip design, impulsive force can be resisted to a certain degree so that by smaller explosion time, reduce damage as much as possible
It is bad, so as to reduce maintenance cost to a certain degree.Meanwhile, pass through the design of guard, it is to avoid the protective plate fragment long drive after blast, with
Exempt to cause secondary injury.
Brief description of the drawings
Fig. 1 is the structure chart of steelframe in the utility model；
Fig. 2 is the structure chart of cell board in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, the protective plate of roofing explosion venting device of the present utility model, including steelframe 1 and nine units
Plate.
Steelframe 1 includes the rectangle frame 11 of nine arrays, and it is welded by the equidistant intertexture anyhow of six roots of sensation steel bar, such as Fig. 1.
Each rectangle frame 11 of steelframe 1 is inner to set a cell board.So, blast impulse can be shared to a certain extent
Power.
Such as Fig. 2, each cell board includes the framework 21 of rectangle, venting of dust explosion flaggy 22, buffering flaggy 23, waterproof lamellar 24, many
Individual stage clip 25, guard 26 and venting of dust explosion bolt 27.
One end of framework 21 is articulated with the side of rectangle frame 11, and the other end is fixed on rectangle frame 21 by venting of dust explosion bolt 27
Opposite side.When having certain impact, venting of dust explosion bolt 27 is acted, and is lost to the spacing of framework 21 so that framework 21 is along being hinged
End upset.
The bottom of framework 21 is extended with four horizontal raised lines 28.
Buffering flaggy 23 is placed in framework 21, is supported by horizontal raised line 28.Waterproof lamellar 24 is fixed on the top of framework 21.
Guard 26 is fixed on the top of framework 21, and positioned at the top of waterproof lamellar 24, in venting of dust explosion, the fragment that cell board is produced is by net
Cover 26 is caught, will not long drive.Venting of dust explosion flaggy 22 is fixed in framework 21, and is close to the bottom surface of waterproof lamellar 24.Each stage clip 25
Top is fixedly connected with venting of dust explosion flaggy 22, and bottom is fixedly connected with buffering flaggy 23.It is all provided between four sides of framework 21 and rectangle frame 11
It is equipped with sealing strip 3.When occurring less explosion time, i.e. impulsive force is insufficient to allow venting of dust explosion bolt 27 to act, and now, impulsive force causes
Buffering flaggy 23 is moved up, and venting of dust explosion flaggy 22 is pushed against through stage clip 25, so as to prevent from damaging as much as possible.
Above example is only for illustration of the utility model, rather than to limitation of the present utility model, relevant technical field
Technical staff, in the case where not departing from spirit and scope of the present utility model, various conversion or modification can also be made, because
This all equivalent technical scheme should also belong to category of the present utility model, should be limited by each claim.
