[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as upper, lower, left, right, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0020] Embodiment 1: A smart urban road lighting device, such as Figure 1-Figure 4 As shown, it includes: a lamp pole 1, the lamp pole 1 is equipped with a protective shell 2, the protective shell 2 is equipped with a support plate 3, the support plate 3 is slidably connected with a lampshade 4, the protective shell 2 is provided with a lighting module 5, and the lighting module 5 is located above the lampshade 4; a scraper 6, rotatably connected to the support plate 3, the scraper 6 is used to clean the surface of the lampshade 4; a driving mechanism is arranged on the support plate 3, and is used to drive the scraper 6 to rotate.

[0021] In the above scheme, the lamp pole 1 and the protective shell 2 are both high-strength steel structures, which are used to ensure the stability of the lamp pole 1 and the protective shell 2 in windy and rainy weather. The lighting module 5 is an existing lighting lamp, which is used to provide lighting light. The lighting module 5 is equipped with a light sensor, a temperature sensor, a humidity sensor and a smoke detector lamp (not specifically shown in the figure) for detecting changes in the external environment and changing the light intensity of the lighting module 5. The lower part of the lampshade 4 is set to be hemispherical, and the scraper 6 is made of high-strength plastic material (which can be polycarbonate), which has high rigidity while avoiding scratches on the surface of the lampshade 4.

[0022] like Figure 2 and Figure 5-Figure 9 As shown, the driving mechanism includes: a sliding shell 7, which is slidably connected to the support plate 3, the sliding shell 7 is slidably connected to the limiting rod 8, and an elastic member is fixedly connected between the two, the limiting rod 8 is provided with a limiting groove, the sliding shell 7 is slidably connected to the first elastic telescopic rod 9, the first elastic telescopic rod 9 is fixedly connected with a first limiting block, and the limiting groove of the limiting rod 8 is used to limit the first limiting block of the first elastic telescopic rod 9; a fixed sleeve 10, which is fixedly connected to the telescopic end of the first elastic telescopic rod 9, a protrusion 11 is fixedly connected in the fixed sleeve 10, a spiral groove 12 is provided on the scraper 6, and the protrusion 11 slides along the spiral groove 12; a second elastic telescopic rod 13, which is fixedly connected to the support plate 3, and two limiting holes are provided on the fixed sleeve 10, and the telescopic end of the second elastic telescopic rod 13 limits the fixed sleeve 10 through the limiting holes of the fixed sleeve 10.

[0023] In the above scheme, a sliding seat is provided on the support plate 3, and the sliding shell 7 slides on the sliding seat of the support plate 3. The elastic member between the sliding shell 7 and the limiting rod 8 is set as a tension spring, which is used to drive the limiting rod 8 to reset. The elastic coefficient of the first elastic telescopic rod 9 is smaller than the elastic coefficient of the second elastic telescopic rod 13. The central angle corresponding to the spiral slide groove 12 is 180°, which prevents the scraper 6 from rotating too much and causing damage to the lampshade 4. The limiting groove of the limiting rod 8 limits the first limiting block of the first elastic telescopic rod 9, so that when the sliding shell 7 moves, it can drive the first elastic telescopic rod 9 to move through the limiting rod 8.

[0024] like Figure 2 and Figure 5-Figure 7As shown, the driving mechanism also includes: a motor 14, which is installed on the protective shell 2, and the support plate 3 is rotatably connected to the transmission rod 16, and the transmission rod 16 is transmission-connected to the output shaft of the motor 14; a reciprocating screw 18, which is fixed to the transmission rod 16, and the reciprocating screw 18 is threadedly connected to the threaded sleeve 19, and the threaded sleeve 19 is fixed to the sliding shell 7; a repelling component, which is arranged on the support plate 3, and is used to repel mosquitoes outside the lampshade 4.

[0025] In the above scheme, the output shaft of the motor 14 rotates continuously in one direction at a relatively slow speed, and the movement of other parts is not affected by centrifugal force. The transmission method between the transmission rod 16 and the output shaft of the motor 14 can be gear transmission. The reciprocating screw 18 is threadedly connected to the threaded sleeve 19 to drive the sliding shell 7 to move back and forth.

[0026] like Figure 2 and Figure 3 As shown, the driving component includes: a first air duct 20, which is fixed to the support plate 3, the first air duct 20 is annular, the first air duct 20 surrounds the outside of the lampshade 4, the first air duct 20 is fixed with a reinforcement ring, and a plurality of nozzles 21 are installed on the reinforcement ring of the first air duct 20, and the nozzles 21 are all connected to the first air duct 20.

[0027] In the above scheme, the first air duct 20 is a hard tube, which is used to provide support force for the reinforcement ring thereon. All nozzles 21 are connected to the first air duct 20 through connecting tubes. The nozzles 21 are directed toward the lowest point of the lampshade 4, so that the gas blown out by the nozzles 21 can completely cover the surface of the lampshade 4 when the lampshade 4 moves up and down.

[0028] like Figure 2-Figure 4 , Figure 7 and Figure 8 As shown, the driving assembly also includes: a fixed shell 22, fixed to the support plate 3, the fixed shell 22 is located between the protective shell 2 and the support plate 3, the fixed shell 22 is fixed and connected with a second air duct 23, the second air duct 23 passes through the support plate 3 and is connected with the first air duct 20, the lampshade 4 is composed of a shell and a ring, and the ring of the lampshade 4 is sealed and slidably connected in the fixed shell 22; a first hydraulic transmission member 24, fixed to the fixed shell 22, the telescopic end of the first hydraulic transmission member 24 is fixed to the ring of the lampshade 4, the support plate 3 is fixed with a second hydraulic transmission member 25, the telescopic end of the second hydraulic transmission member 25 is slidably connected to the sliding shell 7, the telescopic end of the second hydraulic transmission member 25 is fixed with a second limit block, when the limit groove of the limit rod 8 and the first limit block of the first elastic telescopic rod 9 lose their limit, the limit groove of the limit rod 8 and the second limit block of the telescopic end of the second hydraulic transmission member 25 are limited, and an oil guide pipe 26 is connected between the first hydraulic transmission member 24 and the second hydraulic transmission member 25.

[0029] In the above scheme, the fixed shell 22 is an annular shell for storing gas. The first hydraulic transmission component 24 and the second hydraulic transmission component 25 are both composed of a hydraulic shell and a piston rod. The telescopic end of the first hydraulic transmission component 24 is initially in a retracted state, and the telescopic end of the second hydraulic transmission component 25 is initially in an extended state. The first hydraulic transmission component 24, the second hydraulic transmission component 25 and the oil guide pipe 26 are all filled with hydraulic oil for transmission. The telescopic end of the first hydraulic transmission component 24 is used to drive the lampshade 4 to move up and down. The second limit block of the telescopic end of the second hydraulic transmission component 25 and the limit groove of the limit rod 8 limit each other, so that when the sliding shell 7 moves, the telescopic end of the second hydraulic transmission component 25 can be driven to move through the limit rod 8.

[0030] like Figure 5-Figure 7 , Fig.11 and Fig.12 As shown, it also includes: a fixed cylinder 27, which is fixed to the support plate 3, and the fixed cylinder 27 is slidably connected to the third elastic telescopic rod 28, and the telescopic end of the third elastic telescopic rod 28 is fixed to the extrusion block 29, the extrusion block 29 and the limiting rod 8 limit each other, the extrusion block 29 is provided with an inclined surface, and the limiting rod 8 is provided with an inclined groove that is mutually squeezed with the inclined surface of the extrusion block 29; a screw rod 31, which is rotatably connected to the lower part of the lamp pole 1, and the lamp pole 1 is slidably connected to the first sliding plate 32, and the first sliding plate 32 is threadedly connected to the screw rod 31; a first wire sleeve 33, which is fixed between the lamp pole 1 and the fixed cylinder 27, and a first wire core 34 is slidably connected in the first wire sleeve 33, one side of the first wire core 34 is fixed to the first sliding plate 32, and the other side of the first sliding plate 32 is fixed to the third elastic telescopic rod 28.

[0031] In the above scheme, the elastic coefficient of the third elastic telescopic rod 28 is greater than the elastic coefficient of the elastic part between the sliding shell 7 and the limiting rod 8, a maintenance port is provided on the lamp pole 1, and the maintenance port of the lamp pole 1 is provided with a protective cover. The screw 31 is located at the maintenance port of the lamp pole 1, and the screw 31 is used to drive the first sliding plate 32 to move up and down, the first sliding plate 32 is used to drive the first wire core 34 to move, and the first wire core 34 is used to drive the third elastic telescopic rod 28 to move.

[0032] During the use of this device, every night when the device is needed for road lighting, the staff controls the lighting module 5 through the remote control terminal, and the light emitted by the lighting module 5 is irradiated on the road through the lampshade 4 to complete the lighting of the road. When the local season is winter, the staff starts the lighting module 5 through the remote control terminal and simultaneously starts the motor 14. The output shaft of the motor 14 rotates to drive the transmission rod 16 to rotate, and the transmission rod 16 drives the reciprocating screw 18 to rotate. The reciprocating screw 18 rotates and drives the sliding shell 7 to move back and forth through the threaded sleeve 19. The reciprocating movement of the sliding shell 7 drives the first elastic telescopic rod 9 to move back and forth through the limit rod 8.

[0033] During the reciprocating movement of the first elastic telescopic rod 9, due to the limitation of the telescopic end of the second elastic telescopic rod 13 on the upper limit hole of the fixing sleeve 10, the first elastic telescopic rod 9 will not synchronously drive the fixing sleeve 10 to move when it moves, but the telescopic end of the first elastic telescopic rod 9 will be contracted (or extended) first, so that the first elastic telescopic rod 9 accumulates force. During the force accumulation of the first elastic telescopic rod 9, the first elastic telescopic rod 9 continuously applies a thrust (or a pull) to the fixing sleeve 10. When the force applied by the first elastic telescopic rod 9 to the fixing sleeve 10 is greater than the force applied by the second elastic telescopic rod 13 to the upper limit hole of the fixing sleeve 10, the telescopic end of the first elastic telescopic rod 9 pushes (or pulls) the fixing sleeve 10 to move. The movement of the fixing sleeve 10 causes the telescopic end of the second elastic telescopic rod 13 to be retracted. The telescopic end of the second elastic telescopic rod 13 is retracted to release the limitation of the current limiting hole on the fixing sleeve 10. After the limitation of the fixing sleeve 10 is released, the telescopic end of the first elastic telescopic rod 9 quickly extends (or retracts) to drive the fixing sleeve 10 to move quickly.

[0034] During the rapid movement of the fixing sleeve 10, the fixing sleeve 10 drives the protrusion 11 to move, and the protrusion 11 drives the scraper 6 to rotate through the spiral slide groove 12. The scraper 6 rotates to quickly scrape off the frost on the surface of the lampshade 4 until the telescopic end of the first elastic telescopic rod 9 is fully extended (or retracted), and another limiting hole on the fixing sleeve 10 is aligned with the second elastic telescopic rod 13. After the telescopic end of the second elastic telescopic rod 13 is extended to limit the other limiting hole on the fixing sleeve 10, the scraper 6 stops rotating. During the reciprocating movement of the first elastic telescopic rod 9, the above action is continuously repeated, so that the scraper 6 reciprocates and cleans the frost on the surface of the lampshade 4, thereby reducing the interference of frost on the surface of the lampshade 4 on the light irradiation path of the lighting module 5.

[0035] After the local season turns to summer, during the operation of the lighting module 5 at night, mosquitoes in nature will gather in large numbers on the surface of the lampshade 4 due to their unique phototaxis. The mosquitoes gathered on the surface of the lampshade 4 will not only affect the scattering of light from the lighting module 5, but also the excrement of the mosquitoes will remain on the surface of the lampshade 4. After a long period of accumulation, it will further affect the scattering of light from the lighting module 5 and make it difficult to subsequently clean the surface of the lampshade 4.

[0036] When summer comes, the staff rotates the screw rod 31, so that the screw rod 31 drives the first sliding plate 32 to move downward, the first sliding plate 32 moves to pull the first wire core 34 to slide in the first wire sleeve 33, the first wire core 34 moves to pull the third elastic telescopic rod 28 to move rightward, the third elastic telescopic rod 28 moves to drive the extrusion block 29 to move, and the extrusion block 29 contacts the oblique groove of the limiting rod 8 during the movement process, and squeezes the oblique groove of the limiting rod 8, so that the limiting rod 8 moves to the side away from the threaded sleeve 19 and stretches the elastic member on the limiting rod 8, The positioning rod 8 moves the limiting groove on it to release the limiting of the first limiting block on the first elastic telescopic rod 9. At the same time, the limiting groove on the limiting rod 8 limits the second limiting block at the telescopic end of the second hydraulic transmission component 25. Then, after starting the lighting module 5 and the motor 14 at night, the motor 14 drives the threaded sleeve 19 and the sliding shell 7 to reciprocate through the transmission rod 16 and the reciprocating screw 18. At this time, the movement of the sliding shell 7 no longer drives the first elastic telescopic rod 9 to reciprocate, but drives the telescopic end of the second hydraulic transmission component 25 to reciprocate through the limiting rod 8.

[0037] During the reciprocating movement of the sliding shell 7, the inclined groove of the limit rod 8 drives the telescopic end of the third elastic telescopic rod 28 to extend and retract reciprocally through the extrusion block 29, so that the extrusion block 29 always keeps the limit on the limit rod 8. During the process of the limit groove of the limit rod 8 driving the telescopic end of the second hydraulic transmission member 25 to move to the left, the hydraulic oil in the second hydraulic transmission member 25 enters the first hydraulic transmission member 24 through the oil guide pipe 26. The hydraulic oil entering the first hydraulic transmission member 24 drives the telescopic end of the first hydraulic transmission member 24 to extend. During the process of the telescopic end of the first hydraulic transmission member 24 extending, the telescopic end of the first hydraulic transmission member 24 drives the lampshade 4 to move downward. When the lampshade 4 moves downward, air enters the fixed shell 22 through the nozzle 21, the first air guide pipe 20 and the second air guide pipe 23. When the limit rod 8 moves to the right and resets, the above action is performed in reverse to move the lampshade 4 upward.

[0038] When the lampshade 4 moves upward, the air in the fixed shell 22 is blown out through the second air duct 23, the first air duct 20 and the nozzle 21, so as to drive away the mosquitoes on the surface of the lampshade 4. The above-mentioned action is continuously repeated during the process of the telescopic end of the first hydraulic transmission member 24 extending back and forth. While the mosquitoes on the surface of the lampshade 4 are driven away by blowing air, the lampshade 4 moves, thereby increasing the coverage rate of the surface of the lampshade 4 by the nozzle 21. At the same time, the movement of the lampshade 4 itself will also disturb the mosquitoes on it and make them leave the surface of the lampshade 4, thereby reducing the gathering of mosquitoes on the surface of the lampshade 4 and the influence on the light of the lighting module 5.

[0039] When winter comes again, the staff rotates the screw 31 so that the screw 31 drives the first sliding plate 32 to reset. The reset of the first sliding plate 32 releases the pulling force on the first wire core 34, and the first wire core 34 releases the pulling on the third elastic telescopic rod 28, so that the squeezing force of the extrusion block 29 on the inclined groove of the limiting rod 8 disappears. The elastic member on the limiting rod 8 resets under the action of its own elasticity and drives the limiting rod 8 to move and reset, so that the limiting groove of the limiting rod 8 releases the limitation of the second limiting block at the telescopic end of the second hydraulic transmission member 25, and at the same time limits the first limiting block on the first elastic telescopic rod 9 again. Subsequently, the sliding shell 7 and the limiting rod 8 can drive the first elastic telescopic rod 9 to move again, and no longer drive the telescopic end of the second hydraulic transmission member 25 to move.

[0040] When the limit rod 8 is reset, the extrusion block 29 is squeezed through the oblique groove thereon, and the third elastic telescopic rod 28 is driven to move a distance to the left through the extrusion block 29. At this time, the extrusion block 29 is in contact with the oblique groove of the limit rod 8. Thereafter, when the sliding shell 7 moves to the left, the limit rod 8 drives the third elastic telescopic rod 28 to reset through the extrusion block 29, and when the sliding shell 7 moves to the right, the third elastic telescopic rod 28 remains stationary in the original position. The third elastic telescopic rod 28 is reset to pull the first wire core 34 to reset, and the above action is repeated when winter and summer alternate.

[0041] If there is wind at night in winter, the wind will make the temperature of the surface of the lighting device shade lower, and the wind will bring more moisture (moisture in the air). When this moisture comes into contact with the low-temperature surface of the street lamp, it will freeze into frost, causing frost to form on the surface of the lighting device shade faster and thicker when the wind blows.

[0043] In the above scheme, friction materials are provided on the surfaces of the transmission wheel 1401 and the rotating wheel 1601 for stable transmission therebetween. The rotating wheel 1601 initially contacts the side with a smaller diameter of the transmission wheel 1401. The diameter of the transmission wheel 1401 gradually increases from right to left, so that after the rotating wheel 1601 moves to the left, the transmission wheel 1401 can drive the rotating wheel 1601 to rotate faster. The generatrix of the transmission wheel 1401 close to the rotating wheel 1601 is parallel to the horizontal plane.

[0044] like Figure 5-Figure 7 and Fig.10As shown, it also includes: a centrifugal mechanism 35, installed on the protective shell 2, for detecting the size of the wind force; a second wire sleeve 41, fixedly connected between the protective shell 2 and the support plate 3, and a second wire core 42 is slidably connected in the second wire sleeve 41; a second sliding plate 43, slidably connected to the support plate 3, the second sliding plate 43 is rotatably connected to the rotating wheel 1601, one side of the second wire core 42 is fixedly connected to the second sliding plate 43, and the other side of the second wire core 42 is connected to the centrifugal mechanism 35, the third elastic telescopic rod 28 and the second sliding plate 43 squeeze each other, the distance between the third elastic telescopic rod 28 and the second sliding plate 43 is a, and the distance between the extrusion block 29 and the inclined groove of the limiting rod 8 is b, a=b.

[0045] In the above scheme, the centrifugal mechanism 35 is an existing wind force detection device, which is provided with a centrifugal block inside, and the centrifugal block in the centrifugal mechanism 35 is connected to the second wire core 42 through a connecting piece. The greater the wind force, the greater the centrifugal force exerted on the centrifugal block in the centrifugal mechanism 35, so that the centrifugal block in the centrifugal mechanism 35 pulls the second wire core 42 to move through the connecting piece of the centrifugal mechanism 35. When the connecting piece of the centrifugal mechanism 35 pulls the second wire core 42 to move, it can ensure that the second wire core 42 will not be twisted. The second wire core 42 is used to drive the second sliding plate 43 to move, and the movement of the second sliding plate 43 is used to drive the rotating wheel 1601 to move. The third elastic telescopic rod 28 moves to the right to limit the limiting rod 8 by the extrusion block 29, and the third elastic telescopic rod 28 synchronously limits the second sliding plate 43.

[0046] At night in winter, the output shaft of the motor 14 rotates to drive the transmission wheel 1401, the transmission wheel 1401 drives the rotating wheel 1601 to rotate, the rotating wheel 1601 drives the transmission rod 16 to rotate through friction, the transmission rod 16 drives the reciprocating screw 18 to rotate, and finally the sliding shell 7 reciprocates through the first elastic telescopic rod 9 and the fixed sleeve 10 to drive the scraper 6 to clean the lampshade 4. If wind blows during the cleaning of the lampshade 4, the centrifugal mechanism 35 is affected by the wind to pull the second wire core 42 to slide in the second wire sleeve 41, and the second wire core 42 slides in the second wire sleeve 41. The inner movement pulls the second sliding plate 43 to move leftward, and the second sliding plate 43 drives the rotating wheel 1601 to move leftward, and the rotating wheel 1601 slides on the transmission rod 16. The movement of the rotating wheel 1601 increases the transmission speed between it and the transmission wheel 1401, so that the sliding shell 7 moves back and forth faster, and finally the rotation frequency of the scraper 6 is increased. When the wind force is stronger, the transmission speed between the rotating wheel 1601 and the motor 14 is higher, which speeds up the scraper 6 to clean the frost on the surface of the lampshade 4, and reduces the interference of the frost formed on the surface of the lampshade 4 in a short time on the light of the lighting module 5.

[0047] In summer, after the first wire core 34 pulls the third elastic telescopic rod 28 to cause the extrusion block 29 to change the position of the limit rod 8, the third elastic telescopic rod 28 contacts the second sliding plate 43 and limits the second sliding plate 43, so that the second sliding plate 43 remains stationary. When wind blows, the centrifugal mechanism 35 cannot pull the second sliding plate 43 to move through the second wire core 42, thereby maintaining the stability of the position of the rotating wheel 1601 on the transmission rod 16. In winter, the third elastic telescopic rod 28 is reset, and the second sliding plate 43 can move normally. In summer, the position of the rotating wheel 1601 is fixed, thereby reducing the loss between the transmission wheel 1401 and the rotating wheel 1601, and extending the service life of the transmission wheel 1401 and the rotating wheel 1601.

Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
