Similarly, in order to avoid the contact between the winding rope 5 and the surface of the support 6 during the actual setting, a plurality of second supporting rollers are preferably arranged between the reversing roller 4 and the second winding roller 3, the setting form of the second supporting rollers is preferably the same as that of the second winding roller 3, the second supporting rollers comprise a second roller shaft 301 and a plurality of winding wheels 302 arranged on the periphery of the second roller shaft 301, and two ends of the second roller shaft 301 at the moment are respectively and movably connected on the periphery of the support 6 through supports, so that each roller shaft can synchronously rotate with each winding wheel 302, and reliable support is provided for winding and unwinding of the winding rope 5.

Of course, in practical arrangement, the second supporting roller may be provided in a form including a plurality of winding wheels 302, and in this case, each winding wheel 302 may be rotatably connected to the bracket 6, preferably through a base, to achieve reliable supporting when winding and unwinding the winding rope 5.

Obviously, in the specific embodiment 1, the arrangement of the backup rollers may be mainly a plurality of first backup rollers arranged at intervals; in the specific embodiment 2, a first support roller may be provided between the first winding roller 2 and the reversing roller 4, or a plurality of second support rollers may be provided between the reversing roller 4 and the second winding roller 3.

In two preferred embodiments, with the corresponding arrangement of the shade assemblies, an integral shade system can be formed on the support 6, and further, the adjustment of the light transmission capacity of the shade shed can be achieved through the control of the winding and unwinding of the corresponding shade assemblies.

In actual setting, each shading component can be synchronously controlled or independently controlled. Meanwhile, a controller is preferably arranged corresponding to the control of the shading component, and the controller is used for receiving the control instruction to complete the corresponding control of the two driving parts, which is not the focus of the utility model and is not repeated here.

In addition, in order to reduce the maintenance and cleaning difficulty of the shade cloth 1, it is preferable that the shade cloth 1 is coated with a teflon coating.

The retractable shading shed is simple in structure and convenient to set, can flexibly adjust shading amount or light transmission amount of the shading shed while meeting the requirement of shading use of the shading shed, improves the flexibility of adjusting the shading capacity of the shading shed along with environmental change, effectively ensures the adaptation degree of light change when a driver enters and exits a tunnel, reduces potential safety hazards in the tunnel operation process, ensures safe operation of the tunnel, and has good practical value.
