[0022] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0023] Please also read Figures 1 to 6, the city smart street lamp provided by the present invention is now described. The city smart street lamp includes a lamp pole 10, a lighting module 20, a spray assembly 30, a purification assembly 40 and a collection assembly 50. The lighting module 20 is fixedly arranged on the outer periphery of the top of the lamp pole 10; the spray assembly 30 includes a nozzle 31 that can be lifted and lowered on the top of the lamp pole 10, a water storage tank 32 that opens upward and is located in the lamp pole 10, and a water supply device that connects the nozzle 31 and the water storage tank 32; the purification assembly 40 includes a filter 41 arranged on the side wall of the lamp pole 10, a filter element 42 located in the lamp pole 10 and at the same height as the filter 41, an air outlet 43 arranged on the outer periphery of the lamp pole 10, and a wind device 44 connecting the filter 41 and the air outlet 43; the collection assembly 50 is arranged at the bottom of the lamp pole 10, and the collection assembly 50 is used to collect dust at the filter 41 and sediment in the water storage tank 32 respectively.

[0024] It should be noted that Figure 3 The water storage tank 32 in the middle only indicates its structural position, and does not limit the volume of the water storage tank 32 to the size in the figure. In actual use, the volume of the water storage tank 32 can be set according to the actual demand for water storage. And because a street lamp is usually laid at a certain distance on both sides of the road in a road section, the humidity and temperature of the weather in the area can be regulated by spraying through each street lamp. Similarly, the purification component 40, when multiple street lamps are set on both sides of the road in a road section, the purification components 40 in the multiple street lamps can work together to treat the air of the road section, thereby improving the comfort of vehicles and pedestrians passing through the road section.

[0025] Compared with the prior art, the smart street light for urban use provided in this embodiment has a lighting module 20 that is used to illuminate the vehicles on the road when it is dark after the lamp pole 10 is installed on the roadside. When it rains, rainwater enters the water storage tank 32 from the top of the lamp pole 10 for storage. When the weather is hot or dry, the nozzle 31 can be extended for spraying, and the water supply device draws water from the water storage tank 32 for use by the nozzle 31. When the weather pollution index is high, the purification component 40 can be turned on, and the wind device 44 in the purification component 40 is started to draw air from the filter 41 and then pass through the filter 41 and the filter element 42 in turn and then be discharged from the air outlet 43, so as to achieve air purification. After a period of use, the sediment in the water storage tank 32 and the dust on the filter element 42 can be cleaned and accumulated in the collection component 50, and the collection component 50 can be cleaned regularly. The urban smart street lamp of the present invention can not only be used for normal lighting, but also play a role in improving the environment in various severe weather conditions. The water source used by the nozzle 31 can be stored rainwater to reduce energy consumption. The collection component 50 can regularly clean the water tank 32 and the filter element 42, and the service life is long and the effect is good.

[0026] In some embodiments, an improved implementation of the above-mentioned lamp pole 10 may adopt the following structure. Not shown in the figure, the lamp pole 10 is also provided with a distance sensor, a counting sensor and a control system, and the control system is used to receive the measurement values ​​of the distance sensor and the counting sensor and adjust the brightness of the lighting module 20; The control system lowers the brightness of the lighting module 20 to a first brightness value within a preset period of time. Within the preset period of time, when the ranging sensor measures that there is a vehicle within a preset range, the brightness of the lighting module 20 is increased to a second brightness value. When the number of vehicles within the preset range measured by the counting sensor is less than a preset value, the lighting module 20 maintains the first preset time length at the second brightness value. When the number of vehicles within the preset range measured by the counting sensor is above a preset value, the lighting module 20 maintains the second preset time length at the second brightness value. The second preset duration = the first preset duration + (counting sensor measurement value - preset value) * standard value; Among them, the standard value is the length of time required to extend for each additional vehicle.

[0027] Late at night, there are often fewer vehicles, and in remote areas there may be no vehicles passing by all night. In this usage scenario, the brightness of the lighting module 20 can be pre-adjusted, and it will be reduced to a first brightness value within a preset period of time, thereby achieving energy conservation and emission reduction. In addition, within the preset period of time, when the ranging sensor senses that a vehicle has entered its recognition range, it will determine the distance of the vehicle and increase the brightness of the lighting module 20 to a second brightness value during the period of time when the vehicle enters its recognition range. When continuous vehicles enter the recognition range of the ranging sensor, the duration for which the lighting module 20 maintains the second brightness value (i.e., the second preset duration) is calculated by the above formula, thereby reducing overall energy consumption while ensuring that the vehicle lighting is not affected. In addition, lighting at the first brightness value late at night will also reduce light pollution in the environment.

[0028] For example, during the time period of 0:00-4:00, the brightness of the lighting module 20 is adjusted to the first brightness value. During this time period, when the ranging sensor detects a vehicle and the number of vehicles is less than the preset value, when a vehicle enters the measuring range of the ranging sensor, the lighting module 20 is adjusted to the second brightness value and maintained for 10 minutes. When the time is up, it returns to the first brightness value. When the number of vehicles measured by the ranging sensor exceeds the preset value of 5, 2 minutes are added for each of the 5 exceeding vehicles. The time for the lighting module 20 to maintain the second brightness value is 10 minutes plus 5*2, that is, a total of 20 minutes.

[0029] In some embodiments, an improved embodiment of the spray assembly 30 may be as follows: Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5, a cover 11 is provided on the top of the lamp pole 10, and a torsion spring is connected between the lamp poles 10 and the lamp poles 10, and the torsion spring has a pre-tightening force to change the cover 11 to the nozzle 31; the spray assembly 30 also includes a first cylinder 33, the first cylinder 33 is arranged in the lamp pole 10, and the piston rod of the first cylinder 33 is vertically distributed and fixedly connected to the nozzle 31; the water supply device includes a water pipe 34 connected between the nozzle 31 and the water storage tank 32, and a water pump 35 arranged on the water pipe 34. It is easy to think that the cover 11 is rotatably connected to the top of the lamp pole 10.

[0030] The cover 11 on the lamp pole 10 is usually covered on the nozzle 31 to prevent dust from clogging the nozzle 31. When a spraying operation is required, the first cylinder 33 is turned on to drive the nozzle 31 to rise, and the nozzle 31 overcomes the elastic force of the torsion spring to push the cover 11 open, so that the nozzle 31 extends out, and the water pump 35 starts to draw water from the water tank 32 and spray it from the nozzle 31. After the spraying operation is completed, the first cylinder 33 drives the nozzle 31 to descend back into the lamp pole 10, and the torsion spring is restored to drive the cover 11 to cover the nozzle 31 again.

[0031] In this embodiment, the service life of the nozzle 31 can be extended by providing the cover 11 , and the cover 11 can be automatically opened and closed for easy use without affecting the lifting process of the nozzle 31 .

[0032] In some embodiments, a specific implementation of the lamp pole 10 can be as follows: Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5 A plurality of water storage channels 12 are provided in the lamp pole 10, and the plurality of water storage channels 12 are evenly distributed around the axial direction of the nozzle 31. One end of the water storage channel 12 extends to the top surface of the lamp pole 10, and the other end is connected to the water storage tank 32. When it rains, rainwater passes through the water storage channel 12, and the rainwater in the plurality of water storage channels 12 all enters the water storage tank 32, which can increase the amount of rainwater collected, thereby meeting the water demand of the nozzle 31.

[0033] It should be noted that when there is no water in the water tank 32, external water supply can be used to ensure the normal operation of the sprinkler 31. Since current urban construction focuses on greening, there are usually large green belts on both sides of the road, and irrigation heads are usually laid in the green belts. The water tank 32 in the street lamp can use the underground pipes that supply water to the irrigation heads to supply water to itself to cope with the situation of insufficient water in the water tank 32.

[0034] The spray assembly 30 in the embodiment of the present application is compared with the traditional method of humidification using a large humidifier or a spray device. Traditionally, a mobile vehicle is used to spray water mist into the air for humidification and cooling. However, such vehicles cannot work 24 hours a day, consume a lot of manpower and material resources, and the vehicles need to move continuously, and cannot continuously humidify the same place, so the effect is very small. In addition, the cost of such vehicles is much higher than the cost of installing a spray assembly 30 on a street lamp.

[0035] In some embodiments, an improved implementation of the nozzle 31 can be as follows: Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5 The nozzle 31 is provided with a plurality of slots distributed along the upper and lower sides, and the nozzle 31 also includes a plurality of mesh plates 311, and the plurality of mesh plates 311 correspond to the plurality of plug rods one by one and are plugged in and matched. The plurality of mesh plates 311 are superimposed, so that the sprayed water mist can be made finer and denser, and the effect of cooling can be achieved, and water droplets will not adhere to the lighting module 20 to affect the lighting effect. Since the water storage tank 32 is mainly rainwater, which may be mixed with impurities, the bottom mesh plate 311 is easy to be blocked during the spraying process. The mesh plate 311 can be quickly replaced by pulling out the mesh plate 311, and different numbers of mesh plates 311 can be installed to adjust the fineness of the sprayed water mist.

[0036] Specifically, the grids between two adjacent grid plates 311 are staggered.

[0037] In some embodiments, an improved embodiment of the purification component 40 can be implemented as follows: Figure 5 See the structure shown. Figure 5 , the lamp pole 10 is provided with a plurality of air passages 45 connecting the filter screen 41 and the filter element 42, the air passages 45 are evenly distributed around the axis of the filter element 42, a fan connected to the air outlet 43 is provided on the top of the filter element 42, and the fan forms a wind device 44; the purification component 40 also includes a rotating motor 46, the rotating motor 46 is fixedly connected to the filter element 42, and is used to drive the filter element 42 to rotate around its own axis. In order to ensure that the lamp pole 10 is not disconnected, evenly distributed air passages 45 are provided, so that the structure between two adjacent air passages 45 can connect the upper and lower parts of the lamp pole 10, then the outer periphery of the filter element 42 only partially corresponds to the air passage 45, after being used for a period of time, the dust in the air mainly adheres to the position of the filter element 42 corresponding to the air passage 45, at this time, the rotating motor 46 can be started to drive the filter element 42 to rotate, and the clean part of the filter element 42 can be switched to align with the filter element 42, which can extend the service life of each filter element 42 and reduce the cost of use.

[0038] In some embodiments, a specific implementation of the purification component 40 can be as follows: Figure 3 See the structure shown. Figure 3The collecting assembly 50 includes a lifting cover 51 and a second cylinder 52. The lifting cover 51 is sleeved on the outer periphery of the lamp pole 10 and slides with the lamp pole 10 in the up and down directions. A slag outlet is provided on the outer periphery of the lifting cover 51; the second cylinder 52 is provided on the outer periphery of the lamp pole 10, and the piston rod of the second cylinder 52 is vertically distributed and fixedly connected to the lifting cover 51; the lifting cover 51 has a first state where it is located below the filter 41, and a second state where the cover is provided on the outer periphery of the filter 41. When the lifting cover 51 is in the second state, the fan reverses and blows air toward the filter element 42. After using it for a period of time, the external filter 41 is disassembled. The filter 41 is mainly used to block large pieces of garbage such as leaves and garbage bags. The disassembled filter 41 can be cleaned. After the filter 41 is disassembled, the second cylinder 52 drives the lifting cover 51 to rise to the second state. At this time, the fan in the purification component 40 blows back to blow off the dust on the filter element 42, and the dust is intercepted by the lifting cover 51 inside through the air duct 45. After the dust settles in the lifting cover 51, the second cylinder 52 drives the lifting cover 51 to descend to the first state. After the filter 41 is installed, the purification component 40 can be reused, and the dust in the lifting cover 51 can be cleaned once per use, or it can be cleaned regularly.

[0039] In some embodiments, an improved wet method of the water storage tank 32 can be used as follows Figure 5 See the structure shown. Figure 5 A slag discharge pipe 13 is connected between the water storage tank 32 and the air passage 45. The slag discharge pipe 13 is provided with an electric control valve 14. When the lifting cover 51 is in the second state, the electric control valve 14 is opened. When the rainwater in the water storage tank 32 is used up, the slag can be discharged. When discharging the slag, the electric control valve 14 is opened, and the ash in the water storage tank 32 falls into the air passage 45 through the slag discharge pipe 13. When the fan is turned on, the ash falling into the air passage 45 will also be blown into the lifting cover 51 during the process of the fan blowing air into the filter element 42, and the water storage tank 32 and the filter element 42 are cleaned at the same time, which is more efficient.

[0040] Specifically, the bottom of the water storage tank 32 is conical, so the ash in the rainwater will automatically settle on the conical part, making it convenient to thoroughly clean the ash in the water storage tank 32.

[0041] In some implementations, an improved implementation of the above-mentioned smart street lamp for cities can be implemented as follows: Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5 The urban smart street lamp further includes a wind pressure sensor and a reinforcement bracket 60, the wind pressure sensor is arranged on the lamp pole 10; the reinforcement bracket 60 is arranged at the bottom end of the lamp pole 10, the reinforcement bracket 60 is used to be buried underground, and the reinforcement bracket 60 has a telescopic plug rod 64; When the value measured by the wind pressure sensor is above a preset pressure value, the telescopic rod 64 is extended.

[0042] After the lamp pole 10 is installed on the roadside, the reinforcement bracket 60 is buried underground. When the wind pressure sensor detects that the wind force is strong (above the preset pressure value), the telescopic rod 64 on the reinforcement bracket 60 automatically extends and extends deeper into the ground, so as to reinforce the lamp pole 10 and prevent the lamp pole 10 from falling over in windy weather and causing serious traffic accidents; when the wind pressure sensor detects that the wind force is lower than the preset pressure value, the telescopic rod 64 retracts, so as to facilitate the replacement or maintenance of the lamp pole 10.

[0043] In some embodiments, a specific implementation of the reinforcement bracket 60 can be as follows: Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5 The reinforcement bracket 60 also includes a base 61, a slide plate 62, and a third cylinder 63. The base 61 is fixed to the bottom end of the lamp pole 10 and is used to be buried underground. The base 61 has a sliding cavity and a plurality of extension channels located at the bottom of the sliding cavity. The axial direction of the extension channel is at an angle to the axial direction of the lamp pole 10, and the plurality of extension channels are evenly distributed around the axial direction of the lamp pole 10. The slide plate 62 is slidably connected to the sliding cavity along the up and down directions. The third cylinder 63 is arranged in the sliding cavity and is located at the bottom of the slide plate 62. The piston rod of the third cylinder 63 is fixed to the slide plate 62, and the third cylinder 63 is communicatively connected to the wind pressure sensor. There are a plurality of telescopic plug rods 64, and the plurality of telescopic plug rods 64 correspond to the plurality of extension channels one by one and are slidably matched. One end of each telescopic plug rod 64 is rotatably connected to the slide plate 62. Optionally, the base 61 is integrally formed with the lamp pole 10.

[0044] When the wind pressure sensor detects that the wind force is above the preset pressure value, the third cylinder 63 starts to drive the slide plate 62 downward. When the slide plate 62 moves downward, it drives multiple telescopic rods 64 to extend from the extension channel. During the extension and retraction of the telescopic rods 64, the extension channel provides guidance for the telescopic rods 64. This process ensures that the telescopic rods 64 are inserted deeper into the ground.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
