The utility model provides a pier anti-collision device provided with a safety air bag, belongs to the technical field of bridge safety, and particularly relates to a pier protection device. The pier anti-collision device comprises a rectangular anti-collision energy dissipation ring surrounding the periphery of a rectangular pier, and the anti-collision energy dissipation ring surrounds the periphery of the piper, floats on water and can freely drift. The anti-collision energy dissipation ring is provided with a safety air bag device which comprises an impact sensor, a controller, an air generator and the air bag, wherein the impact sensor, the controller and the air generator are arranged in the anti-collision energy dissipation ring, and the air bag is arranged on the inner wall of the anti-collision energy dissipation ring and is connected with the air generator. When a ship impacts on the outer wall of the anti-collision energy dissipation ring, the impact sensor transmits a signal to the controller, the controller triggers the air generator to ignite, a large amount of air is quickly generated, the air bag is unfolded, the formed air bag is clamped between the ship (energy dissipation ring) and the pier, kinetic energy of the ship is greatly absorbed, and an effective buffering function is achieved.
Description
Technical field
The utility model belongs to the technical field of bridge security, particularly a kind of protector of bridge pier.
Background technology
Along with being showing improvement or progress day by day of Science & Society, the size of ship and tonnage, and the density of gap bridge ship all had than in the past significantly and to increase, and the speed of ship is also significantly improving, and the accident of ship collision with piers occurs again and again.About safety and the design of bridge pier, more and more come into one's own.
Boats and ships grazing or while clashing into the bridge pier (comprising bridge pier protection guard) of bridge, kinetic energy is very large, smashing bridge happens occasionally, adopt common anticollision device of pier, because the elastic buffer amount of Anti-collision materials is very limited, can only prevent small-sized ship, or ship that the speed of a ship or plane slightly large slightly larger for quality, the huge kinetic energy that just can not absorb well ship, easily damages bridge pier protection guard and bridge pier itself.
Utility model content
The technical problems to be solved in the utility model is: existing anticollision device of pier, because the elastic buffer amount of Anti-collision materials is very limited, in the time absorbing the huge kinetic energy of accident ship, assimilation effect is undesirable.
The utility model solves the technical scheme that its technical problem adopts: a kind of anticollision device of pier with air bag, comprise and be looped around anticollision energy eliminating circle rectangular pier surrounding, rectangular ring, the cross section of this anticollision energy eliminating circle on rectangular pier is axial is square, anticollision energy eliminating circle comprises lower wall, upper wall, outer wall, inwall
Lower wall is positioned at below the water surface, and inner and outer wall is substantially parallel with the side of bridge pier, and than outer wall, inwall is nearer apart from the distance of the side of bridge pier,
Anticollision energy eliminating circle is enclosed in the surrounding of bridge pier, and it is upper to bubble through the water column, and can freely drift about,
On described anticollision energy eliminating circle, air bag device is installed, air bag device comprises the impact microphone that is arranged on anticollision energy eliminating circle inside, close outer wall; The controller that is arranged on anticollision energy eliminating circle inside, is connected with impact microphone; The gas generator that is arranged on anticollision energy eliminating circle inside, close inwall and is connected with controller; The airbag that be arranged on the inwall of anticollision energy eliminating circle, is connected with gas generator.
When ship will occur to clash into bridge pier, first strike the outer wall of anticollision energy eliminating circle, first experience impact strength near the impact microphone of outer wall, and signal is transferred to controller; Controller judges and sends ignition signal, trigger gas generator, produce rapidly a large amount of gas and launch airbag after gas generator igniting, the air bag of formation is clipped between hull (energy dissipating circle) and bridge pier, the kinetic energy of a large amount of absorption of moment hull, produces effective cushioning effect.
As preferably: the average distance between the inwall of anticollision energy eliminating circle and the side of rectangular pier, be 3-4 times of the square length of side, this is to provide effective space for " after clashing into, airbag launches to form buffer air bag ".If space is too little, air bag cannot normally strut; Or strut in process at air bag, due to stopping of bridge pier, at the explosive force that adds gas moment in the rear airbag of igniting, easily air bag is burst, thereby lost protective action;
As preferably: airbag is positioned at the top of the water surface, this is because the gas generator of airbag and anticollision energy eliminating circle inside links together, if water body soaks airbag, easily takes advantage of a situation and enters into anticollision energy eliminating circle inside, affect the normal work of air bag device

Detailed description of the invention
As shown in Figure 1: the utility model provides a kind of anticollision device of pier with air bag, comprise and be looped around rectangular pier anticollision energy eliminating circle 21 surrounding, rectangular ring,
Concrete structure is as shown in Figure 2: at rectangular pier 1, the cross section on axially be square to this anticollision energy eliminating circle 2, and anticollision energy eliminating circle 2 comprises lower wall 21, upper wall 22, outer wall 23, inwall 24,
Lower wall 22 is positioned at the water surface below 3, and inwall 24 and outer wall 23 are substantially parallel with the side 11 of bridge pier 1, and than outer wall 23, inwall 24 is nearer apart from the distance of the side 11 of bridge pier 1,
Anticollision energy eliminating circle 2 is enclosed in the surrounding of bridge pier 1, and bubbles through the water column on 3, can freely drift about,
On anticollision energy eliminating circle 2, air bag device 4 is installed, air bag device 4 comprises the impact microphone 41 that is arranged on anticollision energy eliminating circle 2 inside, close outer wall 23; The controller 42 that is arranged on anticollision energy eliminating circle 2 inside, is connected with impact microphone 41; The gas generator 43 that is arranged on anticollision energy eliminating circle 2 inside, close inwall 24 and is connected with controller 42; The airbag 44 that be arranged on the inwall 24 of anticollision energy eliminating circle 2, is connected with gas generator 43,
When ship will occur to clash into bridge pier 1, first strike the outer wall 23 of anticollision energy eliminating circle 2, first experience impact strength near the impact microphone 41 of outer wall 23, and signal is transferred to controller 42; Controller 42 judges and sends ignition signal, trigger gas generator 43, after gas generator 43 igniting, produce rapidly a large amount of gas and launch airbag 44, the air bag 44 forming is clipped between hull (energy dissipating circle 2) and bridge pier 1, the kinetic energy of a large amount of absorption of moment hull, produces effective cushioning effect.
Wherein, the average distance between the inwall 24 of anticollision energy eliminating circle 2 and the side 11 of rectangular pier 1, is 3-4 times of the square length of side, and this is to provide effective space for " after clashing into, airbag launches to form buffer air bag ".If space is too little, air bag cannot normally strut; Or strut in process at air bag, due to stopping of bridge pier 1, at the explosive force that adds gas moment in the rear airbag of igniting, easily air bag is burst, thereby lost protective action;
And, airbag 44 is positioned at the top of the water surface 3, and this is because airbag 44 links together with the gas generator 43 of anticollision energy eliminating circle 2 inside, if water body soaks airbag 44, easily take advantage of a situation and enter into anticollision energy eliminating circle 2 inside, affect the normal work of air bag device 4.
