Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
A kind of bridge active collision-avoidance system, structure is shown in Figure 1, for bridge pier component to be protected to avoid being hit,
The bridge pier component includes main pier unit and two abutment piers 3 for being disposed on main pier unit both sides, the main Dun Danyuanbao
It includes the main pier 1 in center for being disposed on centre position and is arranged in the main pier 2 of two avris of main 1 both sides of pier in center, it is described anti-
It hits system and includes the main pier bumper assembly 4 in center, the main pier bumper assembly 5 of avris and abutment pier bumper assembly 6, wherein,
The main pier bumper assembly 4 in center is included along direction along ng a path difference successively symmetrical arranged for interval at main 1 both ends of pier in center
At least one 41 and first early warning of main crash bearer separates pier 42, and 41 and first early warning of main crash bearer positioned at outermost end separates pier 42
Between also lead equipped with the first anticollision cable wire net 43；
The main pier bumper assembly 5 of avris is included along direction along ng a path difference successively symmetrical arranged for interval at main 2 both ends of pier of avris
51 and second early warning of at least one pair crash bearer separates pier 52, and 51 and second early warning of pair crash bearer on the outermost side separates pier 52
Between also lead equipped with the second anticollision cable wire net 53；
Abutment pier bumper assembly 6 includes being arranged symmetrically in 3 both sides of abutment pier successively respectively along direction along ng a path with the navigation channel side
To vertical third anticollision cable wire net 61.
Further, the quantity of the main crash bearer 41 in the main pier bumper assembly 4 in the center can be according to actual needs
Setting can such as be respectively equipped with two at main 1 both ends of pier in center, and main crash bearer 41 is with main crash bearer 41, main crash bearer 41 in
Interval between the main pier 1 of the heart can be arranged as required to, and general warranty is less than the ship that maximum when the main pier 1 in center designs hits grade
The mean breadth of oceangoing ship can ensure that ship can not convert navigation channel in the process of moving in this way.
Further, the second anticollision cable wire net 53 is located at the main pier 2 of avris close to center on vertical direction along ng a path
The side of main pier 1 can limit the traveling-position of ship in this way, prevent it from colliding on the main pier 2 of avris.
Further, the interval between the secondary crash bearer 51 and the main pier 2 of avris can also be set according to actual needs,
Maximum hits the mean breadth of the ship of grade when generally less than the main pier 2 of avris designs, this is being travelled also for guarantee ship
Navigation channel can not be converted in the process.
Further, the width on the base of the main pier 1 in 41 face center of main crash bearer is more than the width of the main pier 1 in center
Degree, can reduce the probability on ship collision to the main pier 1 in center in this way.
Further, the main crash bearer 41 and secondary crash bearer 51 are directed toward the triangle of its residing channel entrance in apex angle
Shape can play the role of guiding ship course, meanwhile, the structure of triangle can also effective buffering collision of closed.
Further, the position of the third anticollision cable wire net 61 and width meet：Its projection energy along direction along ng a path
Abutment pier 3 is completely covered.
Further, it is cylinder to separate 42 and second early warning of pier separation pier 52 for first early warning.
The present invention by the way that first, second early warning is set to separate pier 52 in main waterway, divide in advance by major and minor 51 grade of crash bearer
Main channel is cut, controls ship advance direction along ng a path, accomplishes actively to prevent river channel offset from causing to bump against with main pier.Meanwhile main,
Ship mean breadth when secondary crash bearer 51 and its interval with main pier are less than design during maximum shock grade, ensures that ship exists
Navigation channel (different navigation channel holes) can not be converted in driving process.In addition, crash bearer, which is arranged in main pier, may occur the position of frontal impact
Put, by be classified hit absorb the frontal impact power from ship, while triangle present situation protect to a certain extent main pier not by
Oblique impact acts on.
The above description of the embodiments is intended to facilitate ordinary skill in the art to understand and use the invention.
Person skilled in the art obviously can easily make these embodiments various modifications, and described herein general
Principle is applied in other embodiment without having to go through creative labor.Therefore, the present invention is not limited to above-described embodiment, abilities
Field technique personnel announcement according to the present invention, improvement and modification made without departing from the scope of the present invention all should be the present invention's
Within protection domain.
