Description

Absorption type composite energy dissipation explosion-protection equipment
Technical field
The invention belongs to explosion-proof technology field under water, it is related to a kind of blast resistance construction under water, it is multiple more particularly, to a kind of absorption type Close energy dissipating explosion-protection equipment.
Background technology
With making rapid progress for modern science and technology, the global village of 21 century just like shapes.Due to history, religion, economy, political affairs The reciprocal effect with the intricate factor such as geographical is controlled, human society faces many negative impacts, American politics scholar Hangzhoupro now It is summarized as a kind of conflict of modern civilization and confrontation by booth on a macro scale, thus in post-Cold War period, is gradually formed a kind of another The form of war of class, is international terrorists attack action specifically.
Past talks Dam safety, lays particular stress on the natural disasters such as earthquake, flood more, fresh to refer to less in addition to wartime special circumstances Similar action of terror usually, the risk of artificial destruction.The U.S. after " 911 " attack of terrorism, its people's life, property and public Facility, all suffers from unprecedented threat.Many great installations of country, particularly civilian installation, are all probably terrorist The main object of attack, dam belongs to a kind of large-scale communal facility, is subject to artificial destruction.Therefore, it is considered that insignificant Artificial raid destruction, in the comprehensive new thinking of Dam safety, do not allowed again it is ignored, and one of maximally effective approach i.e. It is to improve or strengthen dam security measures, as an important ring indispensable in dam general safety system.
Existing dam exterior protection technology has:
(1)Using the dam type of more efficient stabilization.As in earth and rockfill dam, rock-fill dams its impervious bodies has thick-layer stockpile and is difficult to receive Damage, homogeneous dam is taken second place, and earth dam with inclined core is weaker, and grit dam is most weak.This safeguard procedures are compared with based on, fixation, but defence capability It is relatively low.
(2)Dam crest sets up armored concrete antiknock body.World War II experience and lessons are drawn by Germany, and antiknock body is set up in dam crest, with Defence bomb penetration explosion.This safeguard procedures have certain protection effect to dam body in itself, but can not eliminate well under water Blasting shock wave, it is impossible to effectively suppress the rough wave effect triggered by explosion.
(3)Set up interior sloping core impervious body.Except the Asphalt Concrete Sloping Core wall antiseepage being normally provided with is external, set up in dam together Interior sloping core impervious body, plays the effect of double protection.
(4)Build discharge structure.Have on dam between the layers of asphalt concrete of face impervious body and build a discharge structure, Monolith every certain length is provided with vertical fragmentation partition wall, just in case certain section of broken ring seepage of dam body, does not influence adjacent regions.
It can be seen that, exterior protection technology generally existing at this stage:Cost is higher, equipment very flexible, device Detachability is poor, to having repaiied, dam interference is big to wait improvements.
The content of the invention
The present invention mainly solves the technical problem existing for prior art;There is provided it is a kind of to dam body interference compared with Small, cost is relatively low;Installing/dismounting is simple, and explosion-proof effect is good;Inhaled using reflector plate reflected-shock wave energy, using energy dissipating flat board Receive shock wave energy and be combined explosion-protection equipment under Double-layer water.
Above-mentioned technical problem of the invention is mainly what is be addressed by following technical proposals:
A kind of absorption type composite energy dissipation explosion-protection equipment, including setting stacked on top of one another reflector plate and energy dissipating flat board, reflector plate Lower surface is Nian Jie with the upper surface of energy dissipating flat board, and the lower surface of the energy dissipating flat board fixes multiple suckers;The reflector plate by Hard material is made;The energy dissipating flat board is mainly made up of elastic plate, and a waveform in sequential like is set inside elastic plate Metallic plate, the corrugated metal plate is located in the space that elastic plate border is constituted;The sucker has through sucker suction face With the passage in non-adsorbed face, the passage is provided with the air plug supporting with it.
Preferably, the density of the reflector plate is 2500g/cm3-8000g/cm3
Preferably, the elastic plate is rubber slab or cystosepiment.
Preferably, upper end of each crest of the corrugated metal plate respectively with elastic plate is concordant, each trough point Lower end not with elastic plate is concordant;Two ends of the two ends of the corrugated metal plate respectively with elastic plate are concordant.This energy dissipating is put down Hardened structure can occur compression simultaneously in the very first time elastic plate of shock wave contact explosion-protection equipment and corrugated steel plate, such as Fruit does not use this preferred structure, and using other structures, such as corrugated metal plate is not each crest, trough and elastic plate Upper and lower end it is concordant, the two ends of corrugated metal plate are not that the two ends all with elastic plate are concordant, and elastic plate can occur first Deformation internal structure arrangement is even closer, and limitation corrugated metal sheet is deformed, and effect of energy dissipation can be reduced.
Preferably, the making material of the corrugated metal plate uses spring steel.
Used as preferential choosing, the adsorption plane of the sucker has a plurality of fold striped, and the fold striped is radially distributed In sucker suction face, the fold striped is strip solid projection or the hollow projection of strip.
Therefore, the invention has the advantages that:
1. when explosion-protection equipment of the present invention works, shock wave travels to reflector plate upper surface first, because reflector plate is by hard Material is made, and can reflect the explosion wave of a part;When remaining explosion wave reaches reflector plate through reflector plate Lower surface, because reflector plate is made up of hard material, reflector plate lower surface produces secondary reflection again to explosion wave Weaken the energy of explosion wave, when remaining explosion wave is communicated to energy dissipating flat board, constitute the elastic plate of energy dissipating flat board And there is compression and absorb portion of energy in the corrugated metal plate embedded in elastic plate, so just make to pass to rushing for dam surface Ripple is hit significantly to weaken;Therefore, explosion-protection equipment of the present invention realizes the combination of reflection energy dissipating and deformation energy dissipating, compared to single reflection Energy dissipating and single deformation energy dissipating, the energy dissipating explosion-proof effect enhancing of explosion-protection equipment of the present invention;
2. absorption type structure is used, sucker suction is being needed into the dam surface of protection when using.To in sucker during dismounting Air this structure is passed through to depart from protection coating naturally, to by protection coating without any damage.
3. modularized design, adapts to curve form, and the scope of application is wider.When more smooth by protection coating, according to quilt The area in the face of protection can make this safeguard structure, and during for being curved surface by protection face, because reflector plate is hard Material matter, the quantity for increasing explosion-protection equipment of the present invention can be taken and the mode of the area that reduces single explosion-protection equipment dam quilt Protection face is arranged explosion-protection equipment.
