[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] Example 1, reference Figures 1 to 4 , which is the first embodiment of the present invention, and provides a combined smart street lamp that can achieve the effect of cleaning the lamp 15, comprising a street lamp body 1, which comprises a bracket body 11, the bracket body 11 has sufficient stability and load-bearing capacity to ensure the normal operation and safe use of the street lamp, a lamp arm 12 and a display screen 13 are installed on the bracket body 11, the lamp arm 12 is located at the top of the bracket body 11, and the lamp arm 12 is mainly used to support the display screen 13, the top plate 14 and the lamp 15, the lamp 15 is installed on the top plate 14, and the display screen 13 is located on the side of the middle of the bracket body 11, and its main function is to clean the lamp 15. The lamp arm 12 is provided with a top plate 14, on which a cleaning mechanism 2 is installed. The cleaning mechanism 2 includes a cleaning roller 21 arranged on the side of the top plate 14 close to the lamp 15. A first mounting block 22 and a second mounting block 23 are installed on the side of the top plate 14 close to the lamp 15. A driving assembly 24 for driving the cleaning roller 21 to move and clean the lamp 15 is arranged on the first mounting block 22 and the second mounting block 23. A processing assembly 25 for removing dirt from the cleaning roller 21 is arranged between the top plate 14 and the second mounting block 23. The bracket body 11, the lamp arm 12, the display screen 13, the top plate 14 and the lamp 15 are all detachably connected, which is convenient for transportation, installation and maintenance of the device; The first mounting block 22 and the second mounting block 23 are detachably connected to the top plate 14, which is convenient for transportation of the device and also convenient for removal and repair when the cleaning mechanism 2 is damaged. By setting the driving component 24, the cleaning roller 21 can be driven to move, so that the cleaning roller 21 cleans the surface of the lamp 15, thereby preventing the lamp 15 from being covered with dust when the lamp 15 is used for a long time, thereby preventing the lighting effect from becoming worse and worse. At the same time, the problem of troublesome manual cleaning is avoided. By setting the processing component 25, the cleaning roller 21 can be cleaned, further increasing the cleaning effect of the cleaning roller 21 on the lamp 15. At the same time, it cooperates with the first mounting block 22, the second mounting block 23 and the driving component 24 to form an annular cover to prevent the lamp 15 from being physically damaged by external flying stones, hail, etc., thereby extending the service life of the lamp 15.

[0023] Furthermore, the lamp 15 uses solar panels in conjunction with the power grid to directly supply power. The basic working principle of solar panels is the photovoltaic effect, that is, when sunlight shines on the surface of the solar panel, the semiconductor material in the solar panel absorbs light energy, generates electron-hole pairs, and generates a potential difference inside the semiconductor, thereby forming voltage and current to supply power to the lamp 15. Solar energy is a renewable energy source that is inexhaustible. As long as there is sunlight, the solar panel can continue to generate electricity, and supplying power to the lamp 15 can significantly reduce electricity bills. In conjunction with the power grid, the power is transmitted to the street lamp, ensuring that when there is insufficient sunlight, the power grid can be used directly for power supply, especially in places where there are many trees on both sides of the road. Under the cover of leaves, it is more difficult for the solar panel to supply power. In conjunction with the power grid, the lamp 15 can be stably supplied with power.

[0024] Furthermore, the driving assembly 24 includes a driving motor 241 arranged on the top plate 14, the output end of the driving motor 241 is fixedly connected to the first driving plate 242, the end of the first driving plate 242 away from the driving motor 241 is connected to the second driving plate 243 through a rotating shaft, the top of the second driving plate 243 is rotatably connected to the first support rod 244, a first sliding groove 245 is opened on the first mounting block 22, the end of the first support rod 244 away from the second driving plate 243 extends to the inside of the first sliding groove 245 and is connected to the first slider 246, one side of the first slider 246 is rotatably connected to the second support rod 247, and the end of the second support rod 247 away from the first slider 246 passes through the first sliding groove 245 and is connected to the cleaning roller 21.

[0025] Furthermore, the first sliding block 246 matches the first sliding groove 245 , ensuring that the first sliding block 246 can only move linearly inside the first sliding groove 245 .

[0026] Furthermore, the driving assembly 24 also includes a rack 248 fixedly installed inside the first slide groove 245, the rack 248 is located at the notch of the first slide groove 245, and a gear 249 is fixedly sleeved on the second support rod 247, the gear 249 matches the rack 248, and the cleaning roller 21 is sleeved on the surface of the second support rod 247. When the first slider 246 moves, the first slider 246 drives the second support rod 247 to move, and the second support rod 247 drives the gear 249 to move, and the gear 249 is meshed with the rack 248. Since the rack 248 cannot rotate, the gear 249 rotates, the gear 249 drives the second support rod 247 to rotate, and the second support rod 247 drives the cleaning roller 21 to rotate, thereby further increasing the cleaning effect on the lamp 15.

[0027] In this embodiment, the cleaning roller 21 is fixedly sleeved on the surface of the second support rod 247; When the lamp 15 needs to be cleaned during use, the driving motor 241 is turned on, and the driving motor 241 drives the first driving plate 242 to rotate, and the first driving plate 242 drives one end connected to the second driving plate 243 to move through the rotating shaft: When the connection between the first driving plate 242 and the second driving plate 243 moves toward the direction of the bracket body 11, the first driving plate 242 drives the first support rod 244 to move toward the direction of the bracket body 11 through the second driving plate 243, and the first support rod 244 drives the first slider 246 to move along the first slide groove 245 toward the direction of the bracket body 11, and the first slider 246 drives the cleaning roller 21 to move toward the direction of the bracket body 11 through the second support rod 247, so that the cleaning roller 21 fits the surface of the lamp 15 and sweeps the dust on the surface of the lamp 15, avoiding the problem of more troublesome manual cleaning, and when the first slider 246 drives the second support rod 247 to move, the second support rod 247 drives the gear 249 to move, and the gear 249 is meshed with the rack 248. Since the rack 248 cannot rotate, the gear 249 rotates, the gear 249 drives the second support rod 247 to rotate, and the second support rod 247 drives the cleaning roller 21 to rotate, further increasing the cleaning effect of the lamp 15; On the contrary, when the connection between the first driving plate 242 and the second driving plate 243 moves in the direction away from the bracket body 11, the first driving plate 242 drives the first support rod 244 to move in the direction away from the bracket body 11 through the second driving plate 243, and the first support rod 244 drives the first slider 246 to move along the first slide groove 245 away from the bracket body 11. The first slider 246 drives the cleaning roller 21 to move in the direction away from the bracket body 11 through the second support rod 247, so that the cleaning roller 21 is in contact with the surface of the lamp 15 again and dust on the surface of the lamp 15 is swept away. At the same time, with the cooperation of the gear 249 and the rack 248, the cleaning roller 21 is reversed to increase the cleaning effect on the lamp 15.

[0028] In summary, in this embodiment, a device for cleaning the surface of the lamp 15 is provided. When in use, there is no need to consider the rotation direction of the drive motor 241. It is only necessary to control the drive motor 241 to turn on to drive the cleaning roller 21 to move back and forth, thereby achieving the cleaning of the surface of the lamp 15. With the cooperation of the gear 249 and the rack 248, the cleaning roller 21 also rotates while moving, further improving the cleaning effect of the lamp 15.

[0029] Example 2, reference Figures 1 to 4, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a processing component 25 of a combined smart street lamp, which further improves the cleaning effect of the lamp 15. The processing component 25 includes a guide frame 251 detachably mounted on the top plate 14, and a filter screen 252 is mounted on the guide frame 251. The tops of the guide frame 251 and the filter screen 252 are both inclined. The guide frame 251 and the filter screen 252 are both arranged to be inclined, so as to prevent fallen leaves and the like from adhering to the surfaces of the guide frame 251 and the filter screen 252 , thereby preventing rainwater from flushing the cleaning roller 21 .

[0030] In this embodiment, it is selected whether to install an ultraviolet lamp according to the situation, and in the initial state, the top plate 14 does not block the cleaning roller 21, and rainwater can pass through the cleaning roller 21; When it rains, rainwater is filtered through the filter 252 to remove large particles of impurities in the rainwater. The treated rainwater is transported to the surface of the cleaning roller 21 through the guide frame 251 to rinse the surface of the cleaning roller 21, making the cleaning roller 21 cleaner, thereby improving the cleaning effect on the surface of the lamp 15.

[0031] The rest of the structure is the same as that of Example 1.

[0032] In summary, in the first embodiment, although the cleaning roller 21 cleans the surface of the lamp 15 while rotating and moving, and has a cleaning effect, since the cleaning roller 21 is exposed to the outside world for a long time, the dust on the surface of the cleaning roller 21 will increase, and the dirty cleaning roller 21 cleans the dirty surface of the lamp 15, so the cleaning effect is poor. In this embodiment, the cleaning roller 21 is cleaned by treating rainwater in nature, so that the cleaning roller 21 is clean, and the clean cleaning roller 21 cleans the dirty surface of the lamp 15, which greatly increases the cleaning effect. In this embodiment, the driving motor 241 drives the cleaning roller 21 to move a After returning, it is necessary to stop for a while, because after the clean cleaning roller 21 wipes the dirty surface of the lamp 15 once, the surface of the lamp 15 may not be wiped clean, and it needs to be wiped several times. At this time, the surface of the cleaning roller 21 is already dirty and is briefly washed by rainwater. The dust on the surface of the cleaning roller 21 from the lamp 15 is still relatively large and wet, resulting in the wet dust easily adhering to the surface of the lamp 15 when cleaning the surface of the lamp 15, resulting in poor cleaning effect. By allowing the cleaning roller 21 to stay in the filtered rainwater for a while, the rainwater and the cleaning roller 21 are rinsed clean, thereby ensuring the cleaning effect.

[0033] Example 3, reference Figures 1 to 5, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a processing component 25 of a combined smart street lamp, which further improves the cleaning effect of the lamp 15. The processing component 25 also includes a second slide groove 253 opened on the second mounting block 23, and a second slider 254 is arranged inside the second slide groove 253. A plurality of support plates 255 are connected to the second slider 254. The plurality of support plates 255 are arranged in a ring shape, and one end of the plurality of support plates 255 away from the second slider 254 passes through the second slide groove 253 and passes through The rotating shaft is connected to a ring block 256. When the multiple support plates 255 rotate or the ring block 256 rotates, the two may not affect each other, that is, when the ring block 256 rotates, the multiple support plates 255 may not rotate. The ring block 256 is sleeved on the surface of the second support rod 247, and the ring block 256 is slidably connected to the second support rod 247. The cleaning roller 21 is located between the gear 249 and the ring block 256. One end of the cleaning roller 21 is fixedly connected to the gear 249, and the other end of the cleaning roller 21 is fixedly connected to the ring block 256.

[0034] Furthermore, the second sliding block 254 is cylindrical, and the second sliding groove 253 includes a horizontal groove 2531 and an oblique groove 2532, and the horizontal groove 2531 and the oblique groove 2532 are connected to each other; Among them, unlike the first slide groove 245, since the first slide groove 245 is a straight groove, the shape of the first slider 246 in the first slide groove 245 does not need to be deliberately limited, and the second slide groove 253 is composed of a horizontal groove 2531 and an inclined groove 2532. When the second slider 254 moves to the connection point between the horizontal groove 2531 and the inclined groove 2532, the second slider 254 is set to a cylindrical shape, which facilitates the movement of the second slider 254 inside the horizontal groove 2531 and the inclined groove 2532.

[0035] Furthermore, the material of the cleaning roller 21 is polybutylene terephthalate. The polybutylene terephthalate brush wire has good wear resistance and resilience, low water absorption, acid and alkali resistance, and a relatively low price. The bending recovery property of polybutylene terephthalate gives it an advantage in cleaning brush wires, and is suitable for cleaning and decontamination of delicate parts.

[0036] The rest of the structure is the same as that of Example 2.

[0037] Different from the first embodiment, in this embodiment, the cleaning roller 21 is slidably sleeved on the surface of the second support rod 247; During use, when the cleaning roller 21 is rinsed, the first slider 246 moves toward the bracket body 11 through the second support rod 247. The second support rod 247 drives the second slider 254 to move inside the second slide groove 253 through the annular block 256 and the support plate 255. When the second slider 254 is in the inclined groove 2532 and moves toward the horizontal groove 2531, the second slider 254 drives the annular block 256 to move toward the gear 249 through the plurality of support plates 255. The ring block 256 is fixedly connected to the second support rod 247, that is, as the ring block 256 moves toward the direction of the gear 249, the distance between the ring block 256 and the gear 249 will become smaller, and at this time, the cleaning roller 21 between the ring block 256 and the gear 249 is squeezed to squeeze out the water on the cleaning roller 21, thereby increasing the cleaning effect of the cleaning roller 21, and at the same time, the lamp 15 will not be affected by moisture, thereby avoiding the risk of circuit short circuit, and also reducing water stains on the surface of the lamp 15, thereby reducing the corrosion problem caused by moisture; On the contrary, when the second slider 254 returns to the inside of the inclined groove 2532 along the horizontal groove 2531, under the action of the inclined groove 2532, the second slider 254 pulls the annular block 256 to return to its original position through the plurality of support plates 255, and the annular block 256 pulls the cleaning roller 21 to return to its original position, so that the cleaning roller 21 can contact more rainwater, thereby improving the cleaning efficiency of the cleaning roller 21; At the same time, the bracket body 11, the first mounting block 22, the second mounting block 23, the cleaning roller 21 and the plurality of support plates 255 form an annular protective cover to prevent the lamp 15 from being physically damaged by external flying rocks, hail, etc., thereby extending the service life of the lamp 15.

[0038] In summary, in the second embodiment, when the cleaning roller 21 is rinsed, a large amount of water will be present on the cleaning roller 21. When the cleaning roller 21 is cleaning the surface of the lamp 15, a large amount of water will also be present on the surface of the lamp 15, which may easily cause corrosion to the accessories of the lamp 15. At the same time, the water stains may also affect the lighting of the lamp 15. This embodiment further optimizes the cleaning roller 21 on the basis of the second embodiment, squeezes the cleaning roller 21, and squeezes out the water on the cleaning roller 21, so as to facilitate the cleaning of the surface of the lamp 15, so that the surface of the lamp 15 is dry after cleaning, which is convenient for the use of the lamp 15. At the same time, it avoids the risk of circuit short circuit, reduces water stains on the surface of the lamp 15, and reduces the corrosion problem caused by moisture.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
