[0027] Specifically, the lifting plate 23 is driven upward by the hydraulic cylinder 22, which drives the lamp holder 24 upward, thereby causing the spotlight 25 to move upward from the inside of the protective box 21 and be located outside the protective box 21. Subsequently, multiple groups of spotlights 25 can be used for lighting, and the inclination angle of the spotlight 25 can be adjusted by the adjustment component 26, so that it can adapt to different road conditions and environments for lighting, and is suitable for use in road environments at different heights to provide the best lighting effect.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] Combination Figure 2 A plurality of groups of irradiation lamps 25 are installed at equal intervals along the length direction of the lamp frame 24 .

[0030] In this embodiment, a plurality of groups of illumination lamps 25 installed at equal intervals along the length direction of the lamp frame 24 can provide a larger illumination range, thereby effectively improving the illumination effect.

[0031] Combination Figure 3The adjustment component 26 includes a base plate 261 arranged at the lower end of the lamp holder 24, and a rotating shaft 262 is provided on both sides of the lamp holder 24. The rotating shaft 262 is used to connect with the base plate 261 and support the lamp holder 24. The rotating shaft 262 is rotatably connected with the base plate 261, and a first gear 263 is sleeved on the outer side of the rotating shaft 262. An electric push rod 264 is installed at the upper end of the base plate 261. A first rack 265 is provided at the output end of the electric push rod 264. The first rack 265 is meshed with the first gear 263. Here, when the first rack 265 is meshed with the first gear 263, the first gear 263 can be driven to rotate when the first rack 265 moves, and the lamp holder 24 is rotated in combination with the rotating shaft 262.

[0032] In this embodiment, when it is necessary to adjust the inclination angle of the illumination lamp 25, the electric push rod 264 is controlled to drive the first rack 265 to move, so that the first rack 265 is engaged to drive the first gear 263 to rotate, and the first gear 263 drives the rotating shaft 262 to rotate, and then the rotating shaft 262 drives the lamp holder 24 to rotate, so that the inclination angle of multiple groups of illumination lamps 25 on the upper end of the lamp holder 24 can be adjusted so that it can adapt to the road environment with different heights. At the same time, because the first rack 265 is engaged with the first gear 263, when the electric push rod 264 is no longer pushing the first rack 265 to move, the position of the first gear 263 is fixed, thereby preventing the rotating shaft 262 from automatically rotating due to gravity factors, thereby avoiding the illumination lamp 25 from automatically rotating.

[0033] Combination Figure 4 The lower end of the bottom plate 261 is fixedly connected with a first connecting shaft 2611, one end of the first connecting shaft 2611 is rotatably connected to the lifting plate 23, the first connecting shaft 2611 is used to support the bottom plate 261 and connect it to the lifting plate 23, a second bevel gear 2612 is provided on the outer side of the first connecting shaft 2611, a motor 231 is installed on the top surface of the lifting plate 23, the output shaft end of the motor 231 is connected with a first bevel gear 232, and the first bevel gear 232 is meshed with the second bevel gear 2612.

[0034] In this embodiment, when it is necessary to adjust the direction of the illumination lamp 25, the first bevel gear 232 is driven to rotate by controlling the motor 231, and due to the meshing of the first bevel gear 232 and the second bevel gear 2612, the first bevel gear 232 is engaged to drive the second bevel gear 2612 to rotate, thereby causing the second bevel gear 2612 to drive the first connecting shaft 2611 to rotate, and the base plate 261 is driven to rotate through the first connecting shaft 2611, and when the base plate 261 rotates under the connection between the rotating shaft 262 and the base plate 261, the lamp holder 24 is driven to rotate, thereby changing the direction of the illumination lamp 25 at the upper end of the lamp holder 24, so that it can adapt to roads with different curves for use, further improving the lighting effect.

[0035] Combination Figure 5The top of the protection box 21 is also rotatably connected with a cover plate 212, and the cover plate 212 is used to cover the protection box 21.

[0036] In this embodiment, when the irradiation lamp 25 is located inside the protection box 21, the top of the protection box 21 can be covered by the cover plate 212 to prevent the irradiation lamp 25 from being exposed to the outside when not in use, thereby avoiding damage caused by external factors.

[0037] Combination Figure 5 A groove 211 is provided on one side of the protective box 21, and a second connecting shaft 214 is rotatably connected inside the groove 211. A connecting ear 213 is fixedly connected to one side of the cover plate 212, and the connecting ear 213 is fixedly connected to the second connecting shaft 214.

[0039] Combination Figure 5 A second gear 215 is sleeved on the outer side of the second connecting shaft 214 , a second rack 233 is provided on the top surface of the lifting plate 23 , and the second rack 233 is meshed with the second gear 215 .

[0040] In this embodiment, when the hydraulic cylinder 22 pushes the lifting plate 23 to move upward, the lifting plate 23 drives the second rack 233 to move upward. Since the second rack 233 is meshed with the second gear 215, when the second rack 233 moves upward, the meshing drives the second gear 215 to rotate, so that the second gear 215 drives the second connecting shaft 214 to rotate, and then drives the cover plate 212 to rotate through the connection between the connecting ear 213 and the second connecting shaft 214, so that the cover plate 212 can rotate during the upward movement of the irradiation lamp 25, so that the top port of the protective box 21 can be opened, (such as Figure 5 (As shown in the figure) when the irradiator 25 moves out from the top of the protective box 21, the second rack 233 separates from the second gear 215, and when the irradiator 25 is used up, the irradiator 25 is reset by the adjustment component 26, and then the lifting plate 23 is driven by the hydraulic cylinder 22 to move into the protective box 21, thereby moving the irradiator 25 into the protective box 21. During the movement, the second rack 233 re-engages with the second gear 215 and drives the second gear 215 to rotate, so that when the irradiator 25 moves into the protective box 21, the cover 212 can cover the top of the protective box 21, thereby protecting the irradiator 25 and preventing it from being exposed to the outside and damaged when not in use.
