Embodiment Construction

[0034] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] An active anti-ship protection device for a bridge, which divides a bridge pier into multiple anti-collision partitions, and the adjacent anti-collision partitions are separated by partition steel piles 19, and the anti-collision partitions are independent of each other; the two ends of the pier 1 are fan-shaped anti-collision The two sides of the middle of the pier 1 are rectangular anti-collision areas; each anti-collision area is composed of a mechanical transmission system, a bottom plate, an energy-absorbing block unit, a rubber buffer block and a control system;

[0036] The mechanical transmission system is composed of partitioned steel piles 19, guide rails, sliders, hydraulic motors 8 and connecting rods; several partitioned steel piles 19 are driven into the foundation near the pier 1 according to the separation positions of the ant...

Abstract

The invention discloses an active protective device for preventing a bridge form the collision of a ship, and belongs to the technical field of roads and bridges. The active protective device consists of an alarm and control unit (18), a mechanical transmission system, a bottom plate, energy-absorbing blocks and a rubber buffer block (7), wherein the alarm and control unit (18) transmits a signal to a gas generator to inflate an inflatable gasbag (6) so as to float up the bottom plate as well as the mechanical transmission device and the energy-absorbing blocks on the bottom plate; the alarm and control unit (18) transmits a signal to a hydraulic motor (8) of the mechanical transmission device and a latch control device so as to enable the rubber buffer block (7) to move forward and change the energy-absorbing blocks arranged on the bottom plate from one row into three rows. The active protective device reduces the occupied space of a collision-preventing device in a navigable region, enhances a collision-preventing and energy-absorbing effect, and achieves the advantages of replaceable energy-absorbing block units and restorable deformation of the buffer block and the like.

Description

technical field [0001] The invention belongs to the technical field of roads and bridges, and in particular relates to the design technology of active anti-collision protection devices for bridge piers, caps, and cable towers of beam bridges, rigid frame bridges, cable-stayed bridges, and suspension bridges. Background technique [0002] At present, with the rise of domestic long-span bridge construction, the risk of collision between ships and bridges cannot be ignored. The traditional anti-collision device system of bridge ship can be divided into: passive anti-collision device system and active anti-collision device system. At present, the passive anti-collision device system is widely used, but the passive anti-collision device system cannot change its shape, which will inevitably cause problems such as occupying the navigable area and affecting the beauty of the bridge. At present, the active collision avoidance system is mostly used for early warning after the ship ya...
