Anti-collision pier structure and active anti-collision method
The invention discloses an anti-collision pier structure that is characterized in that detection water spraying mechanisms are arranged on an upstream face and a downstream face of a pier correspondingly. Each detection water spraying mechanism comprises a laser range finder, a laser velocimeter and a plurality of high-pressure spray heads; a high-pressure water tank is arranged on the riverbed atthe pier and is connected with a high-pressure variable-frequency water pump which is connected with a water inlet pipe; each high-pressure spray head is connected with the high-pressure water tank through a high-pressure water supply hose, and a pressure sensor is arranged in the high-pressure water tank; a waterproof box is arranged at the top of the pier, an electric control device is arrangedin the waterproof box, and the laser range finder, the laser velocimeter, the high-pressure variable-frequency water pump and the pressure sensor are all connected with the electric control device. The invention further discloses a corresponding active anti-collision method. The invention provides an active anti-collision technology, the collision energy of a ship is gradually counteracted through water jet, the instant collision of the ship colliding with a bridge is converted into long-time water spraying collision prevention, and the acting force borne by a pier in unit time is reduced byprolonging the anti-collision action time, so that the pier is effectively protected.
本发明公开了一种防撞桥墩结构，桥墩迎水面和背水面分别设有检测喷水机构，检测喷水机构包括激光测距仪、激光测速仪和若干高压喷头；桥墩处的河床上设有高压水箱，高压水箱连接有高压变频水泵，高压变频水泵连接有进水管；各高压喷头均通过高压供水软管与高压水箱相连接，高压水箱内设有压力传感器；桥墩顶部设有防水箱，防水箱内设有电控装置，激光测距仪、激光测速仪、高压变频水泵和压力传感器均与电控装置相连接。本发明还公开了相应的主动防撞方法。本发明提出了主动防撞技术，通过水射流逐渐抵消船只的撞击能量，将船只撞桥的瞬间撞击转化为长时间喷水防撞，通过延长防撞作用时间降低单位时间内桥墩受到的作用力，从而有效保护桥墩。
