Description
Technical field
The present invention relates to a kind of anti-cyclone grid, specifically, have while being and a kind of higher ventilation rate of offer is provided
Effect stop foreign matter directly through grid.
Background technology
Protective grille in the critical facilitys such as nuclear power station facility, should consider occur the unsafe conditions such as blast when internal
When, grid will play the role of good performance of ventilating to play explosion-proof radiating；In the case of taking portion's normal work into account again,
Grid has enough exterior protection abilities, to meet in the presence of the factors such as high wind, prevents foreign direct from grid
Into inside facility, it is to avoid produce threat to internal safety.
In the prior art, it is also good without that can also have while can keep high ventilation rate, internally explosion-proof heat dispersion
The grid of exterior protection effect.But, current China is greatly developing nuclear energy power generation technology, has built substantial amounts of nuclear power and has set
Apply, have greatly demand again to such grid.Accordingly, it would be desirable to a kind of anti-cyclone grid.
The content of the invention
Technical problem：The present invention provides a kind of can be provided while higher ventilation rate is kept and is well protected against ability
Anti- cyclone grid, it is adaptable to current many critical facilitys, such as nuclear power station, compensate for the sky of domestic correlative technology field at present
In vain.
Technical scheme：The anti-cyclone grid of the present invention, including framework, the multiple horizontal strokes for being arranged on the framework front and rear sides
To connecting rod, it is arranged on rear side of the framework and the longitudinally connected bar orthogonal with transverse connecting rod, in the frame multiple is set
Folded plate type baffle plate, the front side of the framework and rear side, the equidistant hierarchal arrangement of multiple transverse connecting rods are set, the multiple gear
The equidistant hierarchal arrangement of plate is set, each baffle plate rear and front end respectively with a transverse connecting rod being arranged on rear side of framework and one
The individual transverse connecting rod connection being arranged on front side of framework.
Further, in grid of the present invention, framework is character "door" form structure, including 3 pieces are located at upside, left side, right side respectively
And dividing plate connected vertically two-by-two.
Further, in grid of the present invention, baffle plate is L-type folded plate, including two surface plates being connected as a single entity are described two
The angle of surface plate and vertical plane isBending angle angle i.e. in the middle of baffle plate isBending angle both sides, with horizontal stroke on front side of framework
The width of the surface plate connected to connecting rod is l1, and the width for the surface plate being connected with framework posterior lateral connecting rod is l2, and
Meet 1<The relation of l1/l2≤2.
