Water drop type active ship collision prevention device

Abstract

The invention discloses a water drop type active ship collision prevention device which comprises a first collision prevention plate, an inner collision prevention box, buffer structures, a rotating bearing device, a monitoring device used for collecting ship monitoring data, a control system and a first fixing ring. The first collision prevention plate sleeves the lower part of a pier; and the inner collision prevention box is located in the first collision prevention plate. The plurality of buffer structures are arranged between the first collision prevention plate and the inner collision prevention box; a bottom plate is fixedly connected to the bottoms of the first collision prevention plate and the inner collision prevention box; and a first fixing ring is arranged in the inner collision prevention box and tightly attached to the periphery of the pier. A rotating bearing device for driving the first collision prevention plate and the inner collision prevention box to rotate is arranged on the inner collision prevention box; and the monitoring device is fixedly connected above the bridge pier. The active collision prevention device is arranged on the bridge pier, and the ship deviates from the heading direction of the bridge pier by utilizing the rotating force of the device, so that the collision damage of the ship to the bridge pier is greatly reduced, and the serious loss is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge body safety protection, in particular to a water drop type active ship collision prevention device. Background technique [0002] With the continuous development of the transportation industry, a large number of cross-sea and cross-river bridges are constantly being built. Most of the rivers and seas where such bridges are located are busy waterways, and the conditions such as currents, waves, wind and waves are complicated, and the bridge inevitably bears a certain risk of ship collision. In non-conditions, when a ship rubs or hits a bridge pier or anti-collision pier, the momentum of a ship with a certain speed is very large, so its impact force is huge, and bridge damage occurs from time to time. When the pier of the bridge is continuously rubbed by the ship, the huge kinetic energy of the ship is converted into the swing and vibration of the pier when it touches the bridge. The bridge frame is...

Problems solved by technology

The above two existing technologies are fixed on the pier with the pier as the load-bearing point, which belongs to the passive anti-collision structure. When a large-tonnage ship collides with the pier, it will still cause serious damage to the bridge body.
