DETAILED DESCRIPTION

[0018] The implementation of the present application will be described below by specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the present specification. The present application can also be implemented or applied in different specific embodiments, and various modifications or changes can be made to the details in the specification without departing from the spirit of the present application.

[0019] It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to the present specification are only used to understand and read the content disclosed in the specification by those skilled in the art, and are not intended to limit the conditions under which the present application can be implemented. Therefore, any modification of the structure, change of the proportion relationship or adjustment of the size, which does not affect the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the specification are only for the convenience of clear description, and are not intended to limit the scope of the present application. The change or adjustment of the relative relationship without substantially changing the technical content is also considered as the scope of the present application.

[0020] In the present embodiment, as shown in Figure 1 and Figure 2 , an irradiation device for a city rail transit sand table includes a base 1, the base 1 is provided with a support rod 2, the top end of the support rod 2 is a hollow structure and is provided with 2-4 equidistant movable notches 21, the top end of the support rod 2 is also provided with an irradiation adjusting mechanism 3 and a mounting table 4, the mounting table 4 is provided with a battery support 5, and the top end of the battery support 5 is fixedly connected with a solar panel 6.

[0021] Among them, the irradiation mechanism 3 is the core component of the irradiation device for the city rail transit sand table, and its main function is to change the irradiation angle of the irradiation light source 36 to adapt to different use scenarios. As shown in Figure 3As shown in the figure, the irradiation adjusting mechanism 3 comprises a servo motor 31 arranged on the mounting table 4, a threaded rod 32 arranged in the support rod 2, a movable ring 33 arranged on the threaded rod 32, a limiting support 34 arranged on the support rod 2, a connecting rod 35 arranged on the movable ring 33, an irradiation light source 36 arranged at the bottom end of the connecting rod 35, and a fixing mechanism 37 arranged on the limiting support 34.

[0022] In the embodiment, the two ends of the threaded rod 32 are rotatably connected with the support rod 2 and the mounting table 4 respectively, the movable ring 33 is threadedly connected with the threaded rod 32, and the output end of the servo motor 31 is fixedly connected with the top end of the threaded rod 32. The threaded rod 32 can be driven to rotate at the top end of the support rod 2 by the servo motor 31. At this time, since the movable ring 33 is threadedly connected with the threaded rod 32, the top end of the connecting rod 35 is rotatably connected with the movable ring 33, and the bottom end of the connecting rod 35 is connected with the limiting support 34. Therefore, the movable ring 33 will move linearly in the vertical direction along the threaded rod 2, thereby driving the connecting rod 35 to move, changing the included angle between the connecting rod 35 and the limiting support 34, so as to change the irradiation angle of the irradiation light source 36.

[0023] In the embodiment, the main function of the fixing mechanism 37 is to fix the bottom end of the connecting rod 35, so as to prevent the connecting rod 35 from jumping due to the influence of the external environment, thereby preventing the irradiation light from shaking. Figure 4 As shown in the figure, the fixing mechanism 37 comprises an outer support seat 371 arranged at the top end of the limiting support 34, a spring 372 arranged in the outer support seat 371, a top rod 373 arranged in the outer support seat 371, and a squeezing ball head 374 arranged on the top rod 373.

[0024] The top end of the top rod 373 is arranged in the inner part of the outer support seat 371 and is slidably connected with the outer support seat 371. The bottom end of the top rod 373 points to the connecting rod 35 and is fixedly connected with the squeezing ball head 374. When the connecting rod 35 is overlapped with the limiting support 34, the top rod 373 will compress the spring 372 in the outer support seat 371, and the elastic force generated by the compression will push the top rod 373, so that the squeezing ball head 374 at the bottom end of the top rod 373 extrudes the connecting rod 35, thereby starting the fixing function.

[0025] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
