The invention discloses speed measuring equipment for a highway, and belongs to the technical field of highway equipment. A heat insulation plate is fixedly connected to the inner wall of a speed measuring instrument protection shell, a fan and a transparent plate are fixedly connected to one surface of the heat insulation plate, an air guide groove is defined by the surface of the heat insulation plate and the inner wall of the speed measuring instrument protection shell, and one end of the air guide groove communicates with an air blowing hole; according to the speed measuring equipment for the expressway, the fan can cool the interior of the speed measuring instrument protection shell, blown air directly purges the surface of the transparent plate through the air guide groove and the air blowing holes, the functions of dust removal and water removal are achieved, it is guaranteed that the transparent plate is clear and transparent, and the speed measuring equipment for the expressway is high in practicability. And the inclination angle and the rotation direction of the tachymeter protection shell can be adjusted through the arranged shaft seat, the rotating disc and the adjusting disc, so that the installation and debugging convenience of the speed measuring equipment is improved.

    本发明公开了一种高速公路用测速设备,属于公路设备技术领域,测速仪防护壳的内壁固定连接有隔热板,隔热板的一表面固定连接有风机和透明板,隔热板表面与测速仪防护壳的内壁合围有导风槽,导风槽的一端连通有吹风孔,测速仪防护壳的内部固定安装有测速仪本体,该高速公路用测速设备设置的风机可以对测速仪防护壳内部进行散热,而且吹出的风通过导风槽和吹风孔直接对透明板的表面进行吹扫,具有除尘除水的功能,保证了透明板的清晰透明,进而保证了测试仪的拍摄清晰性,并且设置的轴座、旋转盘和调节盘可以对测速仪防护壳的倾斜角度和旋转方向进行调节,提高了测速设备的安装调试便捷性。
