[0005] Furthermore, teeth grooves are evenly formed on one side of the connection plate, and the friction between the connection plate and the high-speed frame is increased through the teeth grooves, so that the connection between the connection plate and the high-speed frame by the protective shell is more stably and firmly connected.
[0006] Furthermore, friction grooves are evenly formed on the bottom of the protective shell, and the friction between the protective shell and the high-speed frame is increased through the friction grooves, so that the protective shell and the high-speed frame are connected more stably and firmly by the protective shell.

When the traffic camera is damaged, it is convenient for the staff to separate the two and replace and repair the traffic camera, thereby increasing the comfort of the staff.
[0009] Compared with the prior art, the beneficial effect of the present invention is that the connecting plate is connected to the high-speed frame by fixing bolts, so that the side protection plates and high-strength spring columns on both sides of the flow camera can limit and fix it. At the same time, the high-strength spring columns on both sides maintain the balance of the flow camera. When strong winds blow towards the flow camera and cause the connecting base to shake and shift, the high-strength spring columns will restore the flow camera to its original position, thereby increasing the detection accuracy of the flow camera.

The tooth groove 5 increases the friction between the connecting plate 4 and the high-speed frame 1, so that the connection between the connecting plate 4 and the high-speed frame 1 by the protective shell 6 is more stable and firm. The friction groove 7 increases the friction between the protective shell 6 and the high-speed frame 1, so that the connection between the protective shell 6 and the high-speed frame 1 is more stable and firm. At the same time, the protective shell 6 is fixed to the solid The fixed bolts 8 are protected, which increases the service life and safety of the fixing bolts 8; at the same time, the high-strength spring columns 9 on both sides maintain the balance of the flow camera 3, so that when a strong wind blows towards the flow camera 3 and causes the connecting base 2 to shake and shift, the high-strength spring columns 9 will restore the flow camera 3 to its original position, thereby increasing the detection accuracy of the flow camera 3; in windy weather, the branches and leaves that fall on the high-speed frame 1 will blow along the high-speed frame 1 toward the flow camera 3. At this time, the side protective plate 10 will intercept them to prevent the branches and leaves from damaging the flow camera 3, thereby increasing the safety and service life of the flow camera 3.
