[0002] During the day, the light outside the tunnel is brighter, but the light inside the tunnel is too dim for the human eye to adapt quickly. Therefore, existing tunnels are equipped with lighting equipment and rely on electricity for lighting. In order to reduce costs and improve environmental protection, some existing highway tunnels use natural light guide lighting, so that the external natural light is transmitted to the tunnel through the light guide structure, realizing the use of renewable energy, improving environmental protection, and saving energy and reducing emissions.

[0003] The prior art, such as the patent with publication number CN216744162U, discloses an anti-glare device for collecting natural light at the entrance of a non-optical tunnel, including a plurality of skylights installed above the outer side of the tunnel entrance cave roof, the skylights are connected to a front angle tube, the front angle tube is a right-angle tube, a light catcher is provided at the connection between the skylight and the front angle tube, the front angle tube is connected to a light guide tube, the length of the light guide tube is between 5 meters and 40 meters, the light guide tube is connected to a light output device through the rear angle tube, the rear angle tube is a right-angle tube; the skylight is connected to the light output device through the front angle tube, the light guide tube and the rear angle tube in sequence, the inner wall of the light guide tube is a mirror structure, and the interior of the front angle tube and the interior of the rear angle tube are respectively installed with light refraction devices. The light is scattered to the tunnel in a diffuse manner through the light output device, so as to achieve an orderly transition of light outside the tunnel and inside the tunnel, and achieve an anti-glare effect.

[0004] The existing technology still has shortcomings:

[0005] The skylight in the above-mentioned prior art needs to be set outside to collect natural light and transmit it into the tunnel, but the skylight lacks a cleaning function, which affects the transmission of light after dust falls. If manual cleaning is too cumbersome, it will affect the use. Therefore, an efficient natural light guide lighting system for highway tunnels is proposed. Utility Model Content

[0009] Preferably, the air outlet pipe is an L-shaped structure, and a plurality of air outlet heads are evenly distributed on the outer wall of the air outlet pipe.

[0010] Preferably, the plurality of air outlet heads are distributed obliquely, and the air outlet heads blow gas obliquely toward the outer wall of the light cover.

[0011] Preferably, the motor drives the gear ring to rotate 180° forwards and backwards through the gear.

[0012] Preferably, a wear-resistant ring is fixedly connected to the outer wall of the air outlet pipe, and the wear-resistant ring is slidably connected to the convex ring and the guide ring.

A guide unit 6 for guiding the cleaning air pipe 5 is installed on the upper surface of the support ring 41.

[0024] like Figure 1-3 As shown, the natural light guide lighting structure in the utility model is similar to the existing natural light guide lighting structure, such as the anti-glare device for collecting natural light at the entrance of a non-optical tunnel disclosed in the patent with publication number CN216744162U. The main improvement of the utility model is to automatically clean the natural light guide lighting to ensure the lighting effect; the skylight 1, the light guide tube 2 and the light output device 3 in the utility model are all prior art, and a light catcher for guiding light is provided in the skylight 1, the light guide tube 2 conducts the light, and the light is finally emitted from the light output device 3 to illuminate the interior of the tunnel with natural light; when the light is daylighted When dust adheres to the outer wall of the cover 1, the motor 43 is started to work, and the interior of the cleaning air pipe 5 is connected to the output end of the external air pump through a pipeline. The external air pump conveys gas to the inside of the cleaning air pipe 5, and the gas is discharged from the cleaning air pipe 5. The motor 43 is supported by the bracket 42, and the bracket 42 and the gear ring 45 are supported by the support ring 41. The motor 43 drives the gear 44 to rotate, and the gear 44 drives the gear ring 45 to rotate, and the gear ring 45 drives the cleaning air pipe 5 to rotate, so that the gas ejected from the cleaning air pipe 5 cleans the surrounding side of the light cover 1 without manual cleaning, so that the outer wall of the light cover 1 is kept clean, the lighting effect is guaranteed, and the illumination of the inside of the tunnel is ensured.

[0025] Among them, the above-mentioned motor 43 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The motor 43 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0026] like Figure 2-4As shown, the cleaning air pipe 5 includes a connecting rod 51, which is fixedly connected to the upper surface of the gear ring 45, and a rotating rod 54 is fixedly connected to the upper end of the connecting rod 51. The outer wall of the rotating rod 54 is rotatably connected to the air outlet pipe 52, and the outer wall of the rotating rod 54 is sleeved with a torsion spring 55. The torsion spring 55 applies torsion to the air outlet pipe 52, and the outer wall of the air outlet pipe 52 is installed with a plurality of connected air outlet heads 53. The guide unit 6 includes a support rod 61, which is fixedly connected to the upper surface of the support ring 41, and a guide ring 62 is fixedly connected to the upper end of the support rod 61. The two ends of the guide ring 62 are fixedly connected to convex rings 63, and the air outlet pipe 52 is slidably connected to the outer walls of the guide ring 62 and the convex ring 63; when the motor 43 drives the gear ring 45 to rotate through the gear 44, the gear ring 45 drives the connecting rod 51 to rotate, and the connecting rod 51 is connected to the outer wall of the guide ring 62 and the convex ring 63. The air outlet pipe 52 is driven to rotate, and the output end of the external air pump is connected to the inside of the air outlet pipe 52 through a pipeline. Under the elastic force of the torsion spring 55, the air outlet pipe 52 is always against the outer wall of the guide ring 62 or the convex ring 63. After the external air pump transports the gas into the air outlet pipe 52, the gas is sprayed out from the air outlet head 53 to clean the outer wall of the light cover 1. When cleaning the outer wall of the light cover 1, the air outlet pipe 52 slides with the outer wall of the guide ring 62, and the guide ring 62 supports the air outlet pipe 52 to make it vertical. After the outer wall of the light cover 1 is cleaned, the motor 43 drives the air outlet pipe 52 to move to contact with the convex ring 63, and the convex ring 63 pushes the outside of the air outlet pipe 52 to rotate the air outlet pipe 52 to an inclined state, so that the upper end of the air outlet pipe 52 is away from the light cover 1, so as to avoid blocking the light cover 1 and affecting the lighting effect, thereby improving practicality.

[0027] like Figure 2 , 3 As shown, the air outlet pipe 52 is an L-shaped structure, and multiple air outlet heads 53 are evenly distributed on the outer wall of the air outlet pipe 52; the L-shaped air outlet pipe 52 can clean the surrounding side and upper end of the light cover 1, improve the cleaning degree of the light cover 1, and improve practicality.

[0028] like Figure 2 As shown, multiple air outlet heads 53 are all distributed obliquely, and the air outlet heads 53 blow gas obliquely toward the outer wall of the light cover 1; the obliquely distributed air outlet heads 53 make the gas blow out obliquely, which can avoid the gas directly blowing into the light cover 1 and causing gas backflow to affect the restriction of dust cleaning on the outer wall of the light cover 1, and can improve the cleaning effect.

[0029] like Figure 2 As shown, the motor 43 drives the gear ring 45 to rotate 180° forward and backward through the gear 44; the outlet pipe 52 can be driven by the motor 43 to rotate 180° forward and backward, which can avoid entanglement of the pipeline connecting the external air pump and the outlet pipe 52, and facilitate the delivery of gas by the outlet pipe 52.

[0030] like Figure 3As shown, the outer wall of the air outlet pipe 52 is fixedly connected with a wear-resistant ring 7, and the wear-resistant ring 7 is slidably connected with the convex ring 63 and the guide ring 62; when the air outlet pipe 52 rotates, the wear-resistant ring 7 slides with the outer walls of the convex ring 63 and the guide ring 62, and the wear-resistant ring 7 can reduce wear.

[0031] The implementation steps in this embodiment are as follows: when dust adheres to the outer wall of the light cover 1, the motor 43 is started to work, the inside of the cleaning air pipe 5 is connected to the external air pump, the external air pump delivers gas to the inside of the air outlet pipe 52, and the gas is discharged from the air outlet head 53, the motor 43 is supported by the bracket 42, the bracket 42 and the gear ring 45 are supported by the support ring 41, the motor 43 drives the gear 44 to rotate, the gear 44 drives the gear ring 45 to rotate, the gear ring 45 drives the connecting rod 51 to rotate, the connecting rod 51 drives the air outlet pipe 52 to rotate through the rotating rod 54, and under the elastic force of the torsion spring 55, the air outlet pipe 52 is always connected with the guide ring 62 or the convex ring 6 3, after the external air pump delivers the gas into the air outlet pipe 52, it is sprayed out from the air outlet head 53 to clean the outer wall of the light hood 1. When cleaning the outer wall of the light hood 1, the air outlet pipe 52 slides with the outer wall of the guide ring 62, and the guide ring 62 supports the air outlet pipe 52 to make it vertical. When the outer wall of the light hood 1 is cleaned, the motor 43 drives the air outlet pipe 52 to move to contact with the convex ring 63, and the convex ring 63 pushes the air outlet pipe 52 outward, so that the air outlet pipe 52 rotates to an inclined state, so that the upper end of the air outlet pipe 52 is away from the light hood 1, and the air outlet pipe 52 does not block the light hood 1.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
