[0023] The pulling structure includes a drainage box 613 fixedly connected to the lower end of the movable column 65, and a water outlet 616 is opened at the lower end of the drainage box 613. The outer surface of the lamp holder body 4 is detachably connected with a protective cover 64 corresponding to the movable column 65. A retraction kit 614 is connected between the protective cover 64 and the drainage box 613, and a pull-back spring 615 is connected between the lower end of the protective cover 64 and the top of the drainage box 613.

[0024] A protective plate 611 is detachably connected to the surface of the lamp frame body 4 corresponding to the intermediate gear 63 and the gear ring 62 . The protective cover 64 is used to protect the movable column 65 together with the rack 66 . The protective plate 611 is used to protect the intermediate gear 63 and the gear ring 62 .

[0025] The number of the limit plates 67 is several groups and they are distributed in a ring array. The intermediate gear 63 and the lamp holder body 4 are rotationally connected, the roller 68 and the rotating ring 61 are rollingly connected, the universal ball 69 and the rotating ring 61 are rollingly connected, and the protruding part of the convex strip 610 is embedded in the corresponding protrusion 612 on the surface of the lamp holder body 4.

[0026] The convex strip 610 is slidably connected to the lamp holder body 4 and the protrusion 612, and the convex strip 610 slides up and down along the lamp holder body 4. The outer diameter of the rotating ring 61 is larger than the outer diameter of the gear ring 62, and the inner diameter of the gear ring 62 is larger than the inner diameter of the rotating ring 61. The scraper plate 60 fits the surface of the lamp body 9. The movable column 65 is slidably connected to the protective cover 64. The interior of the movable column 65 is a hollow columnar structure, and the diameter of the cylinder is equal to the outer diameter of the drain pipe 52.

[0027] The movable column 65 and the drain pipe 52 are slidably connected. The retractable kit 614 is a multi-stage retractable kit for protecting the return spring 615. The lower end of the protective cover 64 is fixed to the upper end of the retractable kit 614. The lower end of the retractable kit 614 is fixedly connected to the drain box 613. The diameter of the water outlet 616 does not exceed one-fourth of the diameter of the movable column 65. The upper and lower elastic ends of the return spring 615 are respectively fixedly connected to the protective cover 64 and the drain box 613.

[0028] In this embodiment, under the condition of water supply from the water storage module 5, the movement of each structure can be automatically controlled, so that the scraper plate 60 can be rotated to clean the surface of the lamp body 9, thereby maintaining the stability of the light emitted by the lamp body 9, obtaining a good lighting effect, and greatly reducing the frequency of manual maintenance and workload. Example

[0029] like Fig.10 As shown, on the basis of Example 2, it is further proposed that the return module 7 includes a fixed bracket 74 fixedly connected to the outer surface of the lamp holder body 4, the outer surface of the fixed bracket 74 is fixedly connected to a waste water tank 71, a micro water pump 72 is arranged inside the waste water tank 71, and a return pipe 73 is fixedly connected between the water outlet end of the micro water pump 72 and the water storage tank 51.

[0030] The upper opening of the wastewater tank 71 corresponds to the lower end of the drainage tank 613, and the return pipe 73 passes through the water storage tank 51 to the interior of the water storage tank 51. The wastewater tank 71 is used to receive the water discharged downward from the drainage tank 613, and the micro water pump 72 is located at a low position inside the wastewater tank 71.

[0031] In this embodiment, the water discharged from the cleaning module 6 can be collected, and when necessary, the water collected inside the wastewater tank 71 can be pumped back into the water storage tank 51, which can improve the utilization rate of collected rainwater and bring better use effects in areas with little rain.

[0032] In summary, the working principle of the present invention is as follows: When in use, the intelligent control terminal 2 automatically controls the lamp body 9 on the lamp frame body 4 to light up, thereby displaying different light effects such as "red, yellow, and green", which can be used to remind drivers and other staff of rail transit, thereby ensuring the safe operation of traffic; During normal use, rainwater generated in nature will fall downwards. Under the guidance of the two sets of guide plates 56, the rainwater will gather inside the water storage tank 51 for storage, and the water flow will be used in the cleaning module 6; After a certain period of use, when the surface of the lamp body 9 needs to be cleaned, the solenoid valve 53 can be automatically controlled to open by the smart control terminal 2. At this time, the water flow in the water storage tank 51 will flow into the inside of the drain pipe 52 under the action of gravity, and then the water flow will flow into the inside of the movable column 65, and finally the water flow will converge into the inside of the drain box 613. Under the action of gravity, the drain box 613 will pull the return spring 615 to move downward. At this time, the flow performance of the water flow is maintained by the connection between the drain pipe 52 and the movable column 65, and in the process of the drain box 613 moving downward, the return spring 615 will be stretched, and the drain box 613 will be compressed at the same time. The retractable sleeve 614 will be unfolded, and the movable column 65 can move downward to drive the rack 66 to move synchronously, and the rack 66 drives the intermediate gear 63 to rotate clockwise, thereby driving the gear ring 62 to rotate counterclockwise. Under the rotation of the gear ring 62, the scraper plate 60 will be driven to rotate accordingly, and the surface of the lamp body 9 will be cleaned by the scraper plate 60, so that there is no need to manually maintain the cleanliness of the surface of the lamp body 9. During the whole process, the amount of water injected into the drainage box 613 by the movable column 65 is much greater than the amount of water discharged from the water outlet 616, so that the accumulated water in the drainage box 613 flows to pull the movable column 65 to move; During the rotation of the gear ring 62, the gear ring 62 drives the rotating ring 61 to rotate accordingly. During the rotation of the rotating ring 61, the position of the rotating ring 61 is limited by the limit plate 67, and the roller 68 and the universal ball 69 roll on the surface of the rotating ring 61, thereby maintaining the stability of the rotation of the rotating ring 61, the gear ring 62 and the scraper plate 60. After one cleaning is completed, the solenoid valve 53 is automatically closed by the intelligent control terminal 2, and the opening of the water outlet 616 at the lower end of the drainage box 613 will continuously discharge water downward, and the weight of the drainage box 613 will continue to decrease, and the pull-back spring 615 will pull the drainage box 613 to move upward. At this time, the movable column 65 will follow the movement, thereby forming an effect of the movable column 65 moving upward in the opposite direction, so that the scraper plate 60 rotates in the opposite direction, and the surface of the lamp body 9 is cleaned again, and the effect is better; The water discharged from the drainage box 613 line will flow into the wastewater tank 71 to achieve the effect of wastewater collection. In water-scarce environments such as summer, the micro water pump 72 can be started through the smart control terminal 2 to pump wastewater into the water storage tank 51 through the return pipe 73, thereby effectively extending the use time of collected rainwater and achieving better use effect.

[0033] It should be noted that the heating plate 55 can heat and melt the collected rainwater in a cold and icy environment, thereby achieving the desired cleaning effect. At the same time, a heating plate 55 can also be added to the inside of the wastewater tank 71 according to actual needs, thereby forming a better water circulation.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
