[0039] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are for illustrative purposes only.

[0040] See also Figure 1-6This embodiment provides a solar tunnel construction lighting system. The subway construction environment includes a tunnel 5 located below ground level 4 and an air shaft 6 connecting the ground level 4 and the tunnel 5. The air shaft facilitates ventilation and lighting within the tunnel. The lighting system comprises a lighting system 1, a light transmission system 2, and a light diffusion assembly 3. Together, these three components transmit sunlight above ground level into tunnel 5 for illumination.

[0041] The lighting system 1 is installed on the side wall of the air shaft 6 close to the ground 4, the light transmission system 2 is installed at the bottom of the air shaft 6 and is arranged opposite to the lighting system 1, and the light diffusion component 3 is fixed on the top of the tunnel 5 and is arranged opposite to the light transmission system 2, so that the lighting system 1 collects sunlight and introduces it into the light diffusion component 3 through the light transmission system 2, and the light diffusion component 3 then diffuses the sunlight into the entire tunnel 5.

[0042] The specific embodiments of the present invention are as follows:

[0043] In order to precisely control the angles of the reflector 12 and the plane mirror 206 and the cleaning effect of the brush, in this embodiment, the lighting drive device 113, the transmission drive device 201, and the brush drive device 1322 all use servo motors.

[0044] A solar-powered tunnel construction lighting system comprises a lighting system 1 and a light transmission system 2 installed on opposite sides of a ventilation shaft 6, and a light diffusion assembly 3 installed at the top of a tunnel 5 for receiving the light source of the light transmission system 2;

[0045] The lighting system 1 includes a reflector 12 and a photosensitive control mechanism 11 for adjusting the angle of the reflector 12. One end of the photosensitive control mechanism 11 is mounted on the side wall of the air shaft 6, and the other end is hinged to the reflector 12 through a connector.

[0046] The optical transmission system 2 includes at least two optical transmission components movably mounted on the side wall of the air shaft 6, and the ends of the optical transmission components are mounted with plane mirrors 206 with adjustable angles;

[0047] The sunlight passes through the reflector 12 and is refracted by the plane mirror 206 to the light diffusion component 3 , and the light diffusion component 3 diffuses the received sunlight and illuminates the tunnel 5 .

[0048] The angle of the reflector 12 is adjusted to receive sunlight. The sunlight is then refracted by the reflector 12 to the first plane mirror in the optical transmission system 2, and then transmitted to the second plane mirror. The second plane mirror refracts the received sunlight onto the light diffusion component 3, which diffuses the received sunlight to illuminate the tunnel 5. The number of optical transmission components and plane mirrors in this system can be set accordingly according to the depth of the tunnel, and can be 2, 3, 4, 5, etc.

[0049] like Figure 2 、 3 As shown, the photosensitivity control mechanism 11 includes a lighting drive device 113 fixedly mounted on the side wall of the air shaft 6, the output shaft of the lighting drive device 113 is fixedly connected to a lighting screw 115, and a lighting screw seat 116 is threadedly sleeved on the lighting screw 115, that is, the lighting screw 115 and the lighting screw seat 116 form a screw mechanism, so that the rotational motion of the lighting drive device 113 is converted into the linear motion of the lighting screw seat 116; the outer wall of the lighting screw seat 116 is fixedly connected to a connecting tube 114, and the connecting tube 114 is hinged to the reflector 12 through a connecting piece; the lighting drive device 113 drives the lighting screw 115 to rotate when it works, so that the lighting screw seat 116 drives the connecting tube 114 to move up and down along the lighting screw 115, and since the two ends of the connecting piece are hinged, the reflector 12 is driven by the connecting piece to adjust the angle.

[0050] The hinge in this embodiment is preferably a rotational connection via a rotating shaft.

[0051] Specifically, the connector includes a connecting rod 111 and a movable rod 112. One end of the connecting rod 111 is threadedly connected to a connecting tube 114, and the other end is hingedly connected to the middle portion of the reflector 12. Each end of the reflector 12 is hingedly connected to the connecting tube 114 via a movable rod 112. One end of the connecting rod 111 is threadedly connected to the connecting tube 114, allowing for adjustment of its length. The two ends of the movable rod 112 are pivotally connected, allowing for adjustment of the angle of the reflector 12. In this embodiment, the movable rods 112 are located at different lengths at each end of the reflector 12, making adjustment more convenient.

[0052] In order to improve the intelligence level of the system, a glass photoreceptor 121 is fixedly provided at the top of the reflector 12, and the output end of the glass photoreceptor 121 is connected to a controller, and the output end of the controller is connected to the lighting drive device 113. The position of the glass photoreceptor 121 is preferably higher than the ground 4, and is used to detect sunlight and collect relevant data. The glass photoreceptor and the controller are both existing commercially available products, and the controller can be a solar tracking controller. The glass photoreceptor receives the light irradiated on its surface and converts the light intensity into an electrical signal output, which is proportional to the light intensity. Therefore, the light intensity can be judged by the electrical signal output by the glass photoreceptor, and the lighting drive device 113 can be controlled by the controller to perform forward and reverse actions, so that the angle of the reflector 12 can be adjusted according to the angle of sunlight, so as to maximize the reception of sunlight.

[0053] like Figure 3As shown, the lighting system 1 also includes an automatic cleaning device 13 for cleaning the surface of the reflector 12. The automatic cleaning device 13 includes a water supply component 131 and a cleaning component 132. The cleaning component 132 includes a brush 1326 that is tightly attached to the surface of the reflector 12. The brush 1326 is driven by a brush driving device 1322 to move up and down along the surface of the reflector 12; the output end of the water supply component 131 is connected to the brush 1326.

[0054] According to a further solution, the brush driving device 1322 is fixedly mounted on the outside of the reflector 12, and a driving end thereof is connected to a threaded rod 1323, a sliding block 1325 is threadedly sleeved on the threaded rod 1323, and the sliding block 1325 is fixedly connected to one end of the brush 1326, and a sponge is provided inside the brush 1326; the brush driving device 1322 drives the threaded rod 1323 to rotate, so that the sliding block 1325 moves linearly on the threaded rod 1323 with the brush 1326; the bottom end of the brush 1326 is connected to the water supply component 131 through the plug-in column 1327 for water supply.

[0055] Specific as Figure 4 As shown, the brush drive device 1322 is fixedly mounted on the top of the reflector 12 via an L-shaped mounting bracket 1321. The output end of the brush drive device 1322 is connected to a threaded rod 1323. The bottom end of the threaded rod 1323 is rotatably connected to a support plate 1324, which is fixedly mounted on the bottom of the reflector 12. That is, the threaded rod 1323 is arranged parallel to the length direction of the reflector 12. The outer periphery of the threaded rod 1323 is threadedly connected to a sliding block 1325, which is fixedly connected to one end of the brush 1326. The brush drive device 1322 is a servo motor. Its operation drives the threaded rod 1323 to rotate, and the sliding block 1325 moves linearly on the threaded rod 1323, thereby driving the brush 1326 to move linearly up and down along the reflector 12, thereby achieving the purpose of cleaning its reflective surface.

[0056] The water supply assembly 131 includes a water tank 1310, which is fixed to the ground 4 and has scale lines 1319 on it, making it easy to observe the water level inside the tank 1310. The bottom of the water tank 1310 is connected to a water tank 1312 via a first pipe 1311. The water tank 1312 can be located in a receiving groove excavated on the side wall of the air shaft 6 for accommodating the photosensitive control mechanism 11. The water tank 1312 is connected to a cleaning tank 1314 via a second pipe 1313. The cleaning tank 1314 is fixedly connected to the bottom end of the reflector 12. The top of the cleaning tank 1314 is provided with a plug port 1315 for connecting to the cleaning assembly 132, which is used to connect to the plug post 1327 in the cleaning group 132.

[0057] Water from water tank 1310 flows through pipe 1 1311, water storage tank 1312, and pipe 2 1313 before entering cleaning tank 1314. This three-stage water storage ensures the reflector remains clean for extended periods, allowing it to fully reflect sunlight. Water supply assembly 131 and cleaning assembly 132 connect via connector 1315 and plug-in post 1327, ensuring a continuous flow of clean water. When the reflector no longer needs cleaning, plug-in post 1327 can be disconnected from connector 1315.

[0058] Specific as Figure 5 As shown, a horizontal baffle 1316 is provided inside the insertion port 1315. The top end of the horizontal baffle 1316 is connected to the inner sidewall of the insertion port 1315 via a spring 1318. A stopper 1317 is fixed to the inner sidewall of the insertion port 1315 above the horizontal baffle 1316 to limit the position of the horizontal baffle 1316. When the brush 1326 moves downward, the plug-in post 1327 at its bottom end enters the insertion port 1315 and presses the horizontal baffle 1316 downward. Water in the cleaning tank 1314 enters the brush 1326 through the plug-in post 1327, filling the sponge in the brush 1326 with water. In addition, since the horizontal baffle 1316 is connected to the spring 1318, it will not fall; when the brush 1326 moves upward, the connecting column 1327 at its bottom end moves away from the plug interface 1315, and the horizontal baffle 1316 returns to its original position under the elastic force of the spring 1318, but is restricted by the limit block 1317 on its upper part, preventing it from detaching from the plug interface 1315 due to excessive elastic force of the spring 1318.

[0059] like Figure 6 As shown, the optical transmission system 2 includes a transmission drive device 201 fixed on the side wall of the air shaft 6, and the output shaft of the transmission drive device 201 is fixedly connected to the bevel gear 1 202, and the bevel gear 1 202 is meshed with the bevel gear 2 203, and the center hole of the bevel gear 203 is fixedly connected to the linkage rod 204, and the two ends of the linkage rod 204 are respectively rotatably installed on the side wall of the air shaft 6. As shown in the figure, a groove is chiseled on the side wall of the air shaft 6, and the linkage rod 204 is vertically arranged in the groove. A bearing is fixed at the top and bottom ends of the groove, and the two ends of the linkage rod are respectively rotatably connected to the bearings; the outer periphery of the two ends of the linkage rod 204 is provided with an external thread, and an optical transmission component is respectively threadedly sleeved; the transmission drive device 201 rotates, and the meshing bevel gear 1 202 and the bevel gear 2 203 drive the linkage rod 204 to rotate, thereby driving the optical transmission component to move up and down on the linkage rod 204.

[0060] Specifically, the optical transmission component includes a transmission screw seat 205 threadedly connected to the linkage rod 204. That is, the linkage rod 204 and the transmission screw seat 205 form a screw mechanism, which converts the rotational motion of the linkage rod 204 into the linear motion of the transmission screw seat 205. The transmission screw seat 205 is fixedly connected to a connecting plate 207. The outer end of the connecting plate 207 is threadedly connected to a support rod 208. The support rod 208 is rotatably connected to the middle portion of the plane mirror 206. One end of the plane mirror 206 is hinged to a telescopic rod 209 fixed to the side wall of the air shaft.

[0061] In a further solution, the light diffusion assembly 3 includes a mounting post 31 fixedly mounted on the top of the tunnel 5 , and a convex lens 32 is connected to the bottom end of the mounting post 31 .

[0062] When the system is in use, the angles of the reflector 12 and the plane mirror 206 are manually adjusted according to the direct angle of sunlight. The sunlight outside is irradiated on the reflector 12, and then refracted by it to the first plane mirror on the optical transmission system 2, and then transmitted to the second plane mirror. The second plane mirror refracts the received sunlight onto the light diffusion component 3, and the light diffusion component 3 diffuses the received sunlight and illuminates the tunnel 5.

[0063] In another embodiment, the glass photoreceptor 121 can convert light into an electrical signal and output it to the controller. The output end of the controller controls the lighting drive device 113 and the transmission drive device 201 respectively. The two servo motors work separately to control the change of the angle of the reflector and the plane mirror, thereby transmitting sunlight into the convex lens 32 in the tunnel, and then diffusing the sunlight into the tunnel.

[0064] When cleaning the reflector 12 , the brush driving device 1322 is manually turned on or controlled by a controller, and the brush 1326 is driven by the sliding block 1325 to move up and down along the threaded rod 1323 , so that the brush 1326 cleans the reflective surface of the reflector 12 .

[0065] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
