Embodiment Construction

[0016] As attached figure 1 Shown: The present invention provides a bridge pier anti-collision device with airbags, which includes a rectangular ring-shaped anti-collision energy dissipation ring 2 surrounding the rectangular bridge pier 1.

[0017] The specific structure is attached figure 2 As shown: the cross section of the anti-collision energy dissipation ring 2 in the axial direction of the rectangular pier 1 is square, and the anti-collision energy dissipation ring 2 includes a lower wall 21, an upper wall 22, an outer wall 23, and an inner wall 24,

[0018] The lower wall 22 is located below the water surface 3. The inner wall 24 and the outer wall 23 are basically parallel to the side 11 of the pier 1. Compared with the outer wall 23, the inner wall 24 is closer to the side 11 of the pier 1.

[0019] The anti-collision energy dissipation ring 2 surrounds the bridge pier 1, and floats on the water surface 3, and can drift freely.

[0020] An airbag device 4 is installed on the...

Abstract

The invention belongs to the technical field of bridge safety and particularly relates to a bridge pier protection device. The bridge pier anti-collision device with a safety air bag comprises a rectangular annular anti-collision energy-dissipation ring surrounding a rectangular bridge pier, wherein the anti-collision energy-dissipation ring surrounds the bridge pier, floats on the water surface and can freely drift. A safety air bag device is installed on the anti-collision energy-dissipation ring and comprises a collision sensor, a controller, an air generator and an air bag arranged on the inner wall of the anti-collision energy-dissipation ring and connected with the air generator, wherein the collision sensor, the controller and the air generator are arranged in the anti-collision energy-dissipation ring. When a ship impacts the outer wall of the anti-collision energy-dissipation ring, the collision sensor transmits a signal to the controller. After the controller triggers the air generator to perform ignition, a large amount of air is rapidly produced to inflate the air bag, and the formed air bag is clamped between a body (energy-dissipation ring) and the bridge pier, absorbs kinetic energy of the body and has the effective buffering effect.

Description

Technical field [0001] The invention belongs to the technical field of bridge safety, and particularly relates to a protection device for bridge piers. Background technique [0002] With the continuous advancement of technology and society, the size and tonnage of ships, as well as the density of ships passing bridges, have increased significantly. The speed of ships has also increased significantly, and accidents of ships colliding with bridge piers have occurred frequently. More and more attention is paid to the safety and design of bridge piers. [0003] When the ship rubs or hits the bridge pier (including the pier protection device), the kinetic energy is very large, and the bridge crash occurs from time to time. The ordinary bridge pier anti-collision device is used. Because the elastic buffer of the anti-collision material is very limited, it can only prevent small For ships with a higher mass or higher speed, the ship’s huge kinetic energy cannot be absorbed well, and the ...
