The invention relates to an adjustable windproof guardrail device and a windproof guardrail system. The device comprises a mounting base, an upper wind shield rotating mechanism arranged at the top of the mounting base, a lower wind shield rotating mechanism arranged at the bottom of the mounting base and a mounting base turnover mechanism in transmission connection with the mounting base. The system comprises a plurality of adjustable windproof guardrail devices which are arranged in parallel. Compared with the prior art, the windproof guardrail can be installed in a special wind-prone zone and a large-span bridge zone, for the special wind-prone zone, the wind-induced damage degree of the guardrail can be reduced by adjusting the angle, and the service life of the windproof guardrail is prolonged; for a large-span bridge zone, the horizontal angle can be adjusted to reduce aerodynamic force load borne by the bridge when the bridge encounters large-grade wind, and the safety of the whole structure of the bridge is guaranteed.
本发明涉及一种可调节式防风护栏装置及防风护栏系统，装置包括安装座、设置在安装座顶部的上挡风板旋转机构、设置在安装座底部的下挡风板旋转机构以及与安装座传动连接的安装座翻转机构；系统包括多个并列设置的可调节式防风护栏装置。与现有技术相比，本发明可安装在特异风多发地带和大跨度桥梁地带，对于特异风多发地带而言，可通过调节角度减小护栏的风致损害程度，增加防风护栏的使用年限；对于大跨度桥梁地带，在大桥遭遇极大等级风时可调整为水平角度减小桥梁承受的气动力载荷，保证桥梁整体结构的安全性。
