Water flow impact prevention device for bridge pier
The invention provides a bridge pier water flow impact prevention device which comprises protection plates clamped on the two sides of a bridge pier in an included angle posture, the ends, close to each other, of the two protection plates are connected through a flow guide plate, and the flow guide plate is made of an elastic material; the two protection plates are arranged on the ring sleeve, the middle portions of the protection plates are connected with the ring sleeve through hinges, and spring dampers are arranged between the protection plates and the ring sleeve. According to the water flow impact prevention device for the bridge pier, on one hand, by designing related vibration buffering and energy absorbing structures, impact energy applied during water flow slapping can be effectively absorbed, and the protection performance is improved; on the other hand, the height of the protection plate can be dynamically adjusted according to the water flow condition without any electric control equipment by designing the liftable protection plate structure and cooperating with the inverted hydrofoil and the reset spring, the protection plate is prevented from being soaked in water for a long time, and the service life of the protection plate and accessory structures of the protection plate is prolonged.
本发明提供了一种桥墩防水流冲击装置，包括以夹角姿态包夹于桥墩两侧的护板，两护板相靠近的一端通过导流板相连，导流板为弹性材质；两护板设置在环套上，护板中部通过铰链与环套相连，护板与环套之间设有弹簧阻尼器。本发明桥墩防水流冲击装置，一方面通过设计相关缓振与吸能结构，能够有效吸收水流拍击时所施加的冲击能量，提升防护性能；另一方面通过设计可升降的护板结构，并配合倒置的水翼和复位弹簧，无需任何电控设备即能够根据水流情况，动态调节护板高度，避免护板长期浸泡于水中，延长护板及其附属结构的使用寿命。
