Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a lifting street light pole that can automatically clean its walls. Background Technology

[0002] The primary function of a streetlight pole is to provide support and secure the structure for the streetlight, allowing it to be stably installed on the road. It is typically made of metal or concrete, possessing sufficient strength and stability to withstand the weight of the streetlight and the effects of the external environment. The height and shape of the streetlight pole can be designed and adjusted according to actual needs to ensure the illumination range and effectiveness of the streetlight.

[0003] Existing street light poles are not easy to adjust in overall height, and their outer surface is difficult to clean once it is stained. Further improvements and optimizations are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a lifting street light pole that can automatically clean its walls, making it easy to adjust the overall height of the street light pole to achieve various lighting effects, and also to clean the stains attached to its outer surface.

[0035] In practical applications, the main body 10 of the street light pole is a lifting structure, which makes it easy to adjust the actual height of the main body 10 of the street light pole to achieve various road lighting effects. The output shaft of the lifting drive motor 154 drives the street light pole lifting drive shaft 151 to rotate through gear transmission. The middle support column 13 of the street light pole, the lower support cylinder 12 of the street light pole, and the upper support cylinder 14 of the street light pole can only slide in the axial direction. Under the drive of the lifting drive shaft 151 of the street light pole, the middle support column 13 of the street light pole, the lower support cylinder 12 of the street light pole, and the upper support cylinder 14 of the street light pole move closer to each other or further away from each other. When the middle support column 13 of the street light pole approaches the lower support cylinder 12 and the upper support cylinder 14 of the street light pole, the overall height of the main body 10 of the street light pole decreases; when the middle support column 13 of the street light pole approaches the lower support cylinder 12 and the upper support cylinder 14 of the street light pole moves away from each other, the overall height of the main body 10 of the street light pole increases. When there are many stains on the outer surface of the street light pole body 10, the street light pole cleaning mechanism 20 is used to clean the outer surface of the street light pole body 10. First, the walking drive mechanism 26 can drive the entire lamp post cleaning mechanism 20 to move up and down along the outer surface of the lamp post body 10 so as to thoroughly clean the outer surface of the lamp post body 10. The inner rod of the radial support drive rod 265 extends out and drives the walking drive sliding cylinder 264, the drive wheel connecting seat 261 and the walking drive wheel 262 to move radially along the lamp post cleaning support ring shell 21, and makes the walking drive wheel 262 gradually approach the outer surface of the lamp post body 10. Finally, the walking drive wheel 262 presses against the support rolling fit on the outer wall of the lamp post body 10. The walking drive wheel 262 is driven to rotate by a servo motor fixed on the drive wheel connecting seat 261 via gear transmission, thereby causing multiple walking drive wheels 262 to drive the entire lamp post cleaning mechanism 20 to move along the outer surface of the lamp post body 10. During the movement of the entire lamp post cleaning mechanism 20, the brush cleaning mechanism 22 is used to clean the dust on the outer surface of the lamp post body 10. The inner rod of the brush close to the drive rod 313 extends and drives the brush to move along the radial direction of the lamp post cleaning support ring shell 21 together with the sliding cylinder 312, the brush support arc plate 223 and the cleaning brush 224, so that the cleaning brush 224 approaches and contacts the outer surface of the lamp post body 10. The brush cleaning rotating ring 222 is driven to rotate by a servo motor fixed in the brush cleaning support ring 221 via gear ring transmission. The brush cleaning rotating ring 222 drives the cleaning brush 224 to rotate around the circumference of the street light pole body 10. The cleaning brush 224 is used to peel off the dust attached to the outer surface of the street light pole body 10. Simultaneously, the dust adsorption mechanism 23 sucks the detached dust into the dust adsorption storage box 233 to prevent the dust from dispersing in the atmosphere and causing secondary pollution to the urban air. The air pump 236 continuously evacuates the inside of the dust adsorption storage box 233, so that the inside of the dust adsorption storage box 233 is continuously in a negative pressure state. Under the action of negative pressure, the detached dust enters the dust adsorption ring shell 231 through the dust adsorption through hole 2310. The detached dust then enters the inside of the dust adsorption storage box 233 through the dust adsorption conveying pipe 234, and is intercepted and stored in the dust collection bag 235. After cleaning the dust off the outer surface of the lamp post body 10, the high-pressure flushing mechanism 24 is used to flush and clean the outer surface of the lamp post body 10. The flushing and cleaning conveying pump 246 delivers the water in the cleaning water storage tank 245 to each high-pressure flushing conveying pipe 243. The water in each high-pressure flushing conveying pipe 243 is then sprayed out from the high-pressure flushing nozzle 244, and the high-speed water flow is used to flush and clean the outer surface of the lamp post body 10. The wastewater recycling mechanism 25 is used to recycle the wastewater generated by flushing and cleaning. The inner rod of the wastewater recycling drive rod 255 extends and drives the wastewater recycling moving cylinder 252, the recycling pipe support plate 253 and the wastewater recycling arc pipe 254 together to move closer to the outer surface of the street light pole body 10, so that the side of the wastewater recycling arc pipe 254 with the wastewater recycling hole 2540 is close to the outer surface of the street light pole body 10. The negative pressure suction pump 258 is used to evacuate the inside of the sewage storage tank 256, so that the inside of the sewage storage tank 256 and the inside of each sewage recovery arc pipe 254 are in a negative pressure state. Under the action of negative pressure, the sewage generated by flushing and cleaning will be sucked into the sewage recovery arc pipe 254 through the sewage recovery hole 2540. The sewage inside the sewage recovery arc pipe 254 then enters the sewage storage tank 256 for storage through the sewage delivery pipe 257.

[0036] When the water in the cleaning water storage tank 245 is used up, the entire lamp post cleaning mechanism 20 is lowered to its lowest point and water is replenished manually. When the sewage storage tank 256 is full, it is emptied manually.

[0037] It should be noted that the lifting drive motor 154, dust collection bag 235, air extractor 236, high-pressure flushing nozzle 244, flushing and cleaning conveying pump 246, and negative pressure suction pump 258 used in this application are all products of existing technology and are not specifically limited here.
