Description

Technical Field

[0001] This invention relates to the technical field of functional features or components of lighting devices or systems, and in particular to a smart street light capable of monitoring the environment and automatically spraying dust removal. Background Technology

[0003] The existing smart streetlights still have shortcomings in environmental management: some streetlights with sprinkler systems spray pedestrians or non-motorized vehicles during the spraying process, causing inconvenience to pedestrians. In addition, on some tall roads with insufficient greenery, pedestrians and pedestrians lack shade under the scorching sun. To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that streetlights with sprinkler systems can easily spray water onto pedestrians and non-motorized vehicles, causing inconvenience to pedestrians, and that on roads with insufficient greenery and lack of shade, it is difficult to simultaneously achieve adequate water spraying and provide shade for pedestrians.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart street light capable of monitoring the environment and automatically spraying dust removal, comprising a light pole and a light body fixed at the top of the light pole, wherein a monitoring instrument and a first solar panel are fixedly installed on the light pole, the light pole is provided with a spraying mechanism for multi-angle spraying dust removal and a water supply mechanism for supplying water to the spraying mechanism, and an installation frame is fixedly installed on the light pole below the spraying mechanism, the installation frame is provided with a shielding mechanism, and a monitoring camera is fixedly installed on the light pole at the bottom of the shielding mechanism; The shielding mechanism includes a third motor fixed to the top of the mounting frame. The output end of the third motor is fixed with a rotating shaft. There are several mounting frames distributed around the lamp post at the same height. There are several rotating shafts, one of which is fixedly connected to the third motor. The remaining rotating shafts rotate through a transmission assembly. Each mounting frame is rotatably connected to two rotating shafts. Each rotating shaft is fixed with a connecting cylinder. A fan-shaped baffle is fixed on the connecting cylinder. A second solar panel is fixed to the top of the fan-shaped baffle, and a lamp strip is fixed to the bottom of the fan-shaped baffle.

[0006] Furthermore, the transmission assembly includes a third gear keyed to the rotating shaft, with several third gears located at the same height and two third gears meshing within the same mounting frame.

[0007] Furthermore, a first bevel gear is keyed to the bottom end of one of the rotating shafts within each of the mounting frames. A mounting component is fixed on the lamp post, and a drive shaft is rotatably connected within the mounting component. A second bevel gear meshing with the first bevel gear is keyed to the drive shaft, and a third bevel gear is provided at the end of the drive shaft. The number of drive shafts is the same as that of the mounting frames. The opposite ends of two adjacent drive shafts are keyed to the third bevel gear, and both ends of the remaining drive shafts are keyed to the third bevel gear, with adjacent third bevel gears meshing.

[0008] Furthermore, the mounting component is rotatably connected to the drive shaft via a bearing.

[0009] Furthermore, a housing is fixed on the lamp post, and a sprinkler mechanism is located inside the housing. The sprinkler mechanism includes a first motor fixed inside the housing, a first gear fixed at the output end of the first motor, a fixed cylinder fixed on the lamp post, a rotating cylinder rotatably connected to the fixed cylinder, the rotating cylinder extending vertically to the bottom of the housing, a second gear meshing with the first gear at the position of the rotating cylinder inside the housing, a connecting plate fixed at the lower end of the rotating cylinder, and a sprinkler head mounted on the lower end of the connecting plate via a rotating assembly.

[0010] Furthermore, the rotating assembly includes a fixed frame fixed to the bottom of the connecting plate, a second motor fixedly installed on one side of the fixed frame, a rotating frame fixed to the output end of the second motor, and the spray head fixed inside the rotating frame.

[0011] Furthermore, the water supply mechanism includes a spray box, a water pipe is connected to the spray box via a flange, a flexible hose is connected to the flange at the end of the water pipe away from the spray box, and the end of the flexible hose away from the water pipe is connected to the flange of the spray head.

[0012] Furthermore, a protective shell is fixed between the spray box and the light pole, and an installation groove is provided inside the light pole, with the water pipe placed inside the installation groove and the protective shell.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This smart street light, capable of monitoring the environment and automatically spraying dust, uses a transmission component to form a circumferentially opening and closing fan-shaped baffle. When open, it provides water mist or sunlight shielding; when closed, it creates space for water mist spraying. Solar panels and light strips are installed above and below the fan-shaped baffle, respectively. The baffle, while shielding sunlight, participates in converting solar energy into electricity, achieving more efficient resource utilization. The light strips below the fan-shaped baffle provide stable illumination for the monitoring camera while it detects pedestrians approaching. Furthermore, due to their different power supply from the main light unit, they provide continuous road lighting during maintenance or repair of the main light unit.

[0014] 2. This smart street light, capable of monitoring the environment and automatically spraying dust, achieves horizontal or vertical rotation through a spraying mechanism and rotating components. This allows the spray head to spray simultaneously in both circular and vertical rotation around the light pole, increasing the spraying range and solving the problem of a small spraying range caused by the spray head being integrated and fixed on the light pole.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-3 As shown, the smart street light of this embodiment, which can monitor the environment and automatically spray dust removal, includes a light pole 1 and a light body 10 fixed at the top of the light pole 1. A monitoring instrument 2 and a first solar panel 3 are fixedly installed on the light pole 1 by a triangular bracket and bolts. The light pole 1 is provided with a spraying mechanism 5 for multi-angle spray dust removal and a water supply mechanism 9 for supplying water to the spraying mechanism 5. An installation frame 6 is fixed on the light pole 1 at a position below the spraying mechanism 5. A shielding mechanism 7 is provided on the installation frame 6. A monitoring camera 12 is fixedly installed on the light pole 1 at the bottom of the shielding mechanism 7. The top of the monitor 2 is equipped with sampling modules such as a gas louver box, wind speed and direction sensor, rain gauge, air temperature and humidity sensor, and dust detector. The microcontroller that processes sensor signals and executes detection logic, the storage unit mainly composed of small Flash chips, and the data processing and control modules such as calibration circuit are located inside the enclosure. It achieves 4G signal transmission through a built-in small ceramic antenna. The enclosure is equipped with a main power supply and an auxiliary power supply. The first solar panel 3 is electrically connected to the solar controller and battery located inside the monitor 2 enclosure, serving as an auxiliary power supply to provide power to the lamp body 10 and the monitor 2. The lamp post 1 is fixed with a display screen by bolts to display the environmental monitoring results. The surveillance camera 12 is connected to an independent intelligent analysis box, which is connected to the camera via a network cable or coaxial cable. It receives and processes video signals, analyzes the real-time video stream collected by the surveillance camera 12, accurately identifies pedestrians and non-motorized vehicles, and eliminates interfering targets such as motor vehicles, fallen leaves, and light and shadow. The surveillance camera 12 is also electrically connected to an external control box, which contains an STM32 microcontroller and a motor driver.

[0019] like Figures 4-6As shown, the shielding mechanism 7 includes a third motor 701 fixed to the top of the mounting frame 6 by bolts. The output end of the third motor 701 is fixed to a rotating shaft 702 by a coupling. The coupling is located in a through hole at the top of the mounting frame 6 for the output end of the third motor 701 to pass through. There are several mounting frames 6 distributed around the lamp post 1 at the same height. The number of mounting frames 6 is not less than the number of rotating shafts 702 placed at the edge of the cross-sectional shape of the lamp post 1. One rotating shaft 702 is fixedly connected to the third motor 701, and the remaining rotating shafts 702 are rotated through a transmission assembly. Each mounting frame 6 is rotatably connected to two rotating shafts 702. Each rotating shaft 702 is fixed with a connecting cylinder 704. A fan-shaped baffle 710 is fixed on the connecting cylinder 704. A second solar panel 8 is fixed to the top of the fan-shaped baffle 710, and a light strip 11 is fixed to the bottom of the fan-shaped baffle 710. The third motor 701 is a Dongfang Motor BLH model. When the intelligent analysis box connected to the monitoring camera 12 detects a pedestrian or non-motorized vehicle in the real-time video captured by the monitoring camera 12, the microcontroller drives the output terminal of the third motor 701 to rotate through the motor driver. The third motor 701 drives the rotating shaft 702 to rotate, and the transmission assembly enables all rotating shafts 702 to rotate. The connecting cylinder 704 rotates with the rotating shaft 702, and the sector-shaped baffle 710 rotates in opposite directions with the connecting cylinder 704. During the rotation of the sector-shaped baffle 710, the shielding coverage area is increased to block the water mist or sunlight in the spray, improving pedestrian comfort. After no pedestrian is detected, the third motor 701 rotates in the reverse direction to achieve positioning. Two fan-shaped baffles 710 on the same mounting frame 6 are nearly overlapping, allowing space between the fan-shaped baffles 710 on adjacent mounting frames 6 for water mist to fall and suppress dust. The second solar panel 8 is an irregularly shaped solar panel, the specific shape of which corresponds to the upper surface of the fan-shaped baffle 710. A waterproof box is placed next to the light pole 1. The waterproof box contains a solar controller and a battery that converts the solar energy collected by the second solar panel 8 into electrical energy as an auxiliary power source for the spray box 901, the third motor 701, and the light strip 11. The light strip 11 is a constantly lit LED light, which enhances the lighting, improves the image quality of the monitoring camera 12, and temporarily replaces the road lighting when the light body 10 is under maintenance, thus maintaining continuous lighting on the road.

[0020] like Figure 6-Figure 8As shown, the transmission assembly includes a third gear 703 keyed to a rotating shaft 702. Several third gears 703 are located at the same height, and two third gears 703 located in the same mounting frame 6 mesh. A first bevel gear 705 is keyed to the bottom end of one of the rotating shafts 702 in each mounting frame 6. A mounting piece 708 is fixed on the lamp post 1. A transmission shaft 706 is rotatably connected in the mounting piece 708. The mounting piece 708 is rotatably connected to the transmission shaft 706 through a bearing. A second bevel gear 707 that meshes with the first bevel gear 705 is keyed to the transmission shaft 706, and a third bevel gear 709 is provided at the end of the transmission shaft 706. The number of transmission shafts 706 is the same as that of the mounting frame 6. The opposite ends of two adjacent transmission shafts 706 are keyed to the third bevel gear 709, and both ends of the remaining transmission shafts 706 are keyed to the third bevel gear 709. Two adjacent third bevel gears 709 mesh. The third motor 701 drives the rotating shaft 702 fixedly connected to it to rotate. The third gear 703 on the rotating shaft 702 transmits the rotation to the adjacent rotating shaft 702. The first bevel gear 705 under the rotating shaft 702 rotates with the rotating shaft 702, the second bevel gear 707 rotates with the first bevel gear 705, the transmission shaft 706 rotates with the second bevel gear 707, and the third bevel gear 709 rotates with the transmission shaft 706. The third bevel gear 709 transmits to another third bevel gear 709 that meshes with it and is keyed to the adjacent transmission shaft 706, causing the adjacent transmission shaft 706 to rotate. The second bevel gear 707 on the adjacent transmission shaft 706 then rotates and transmits to the meshing first bevel gear 705, realizing the rotation of the rotating shaft 702 in the adjacent mounting frame 6. This process can be repeated to realize the simultaneous rotation of each rotating shaft 702, realizing the rotation of several rotating shafts 702 distributed in a ring by one motor.

[0021] like Figures 9-10 As shown, a housing 4 is fixed on the lamp post 1, and a sprinkler mechanism 5 is located inside the housing 4. The sprinkler mechanism 5 includes a first motor 501 fixed inside the housing 4, a first gear 502 fixed at the output end of the first motor 501, a fixed cylinder 504 fixed on the lamp post 1, a rotating cylinder 505 rotatably connected to the fixed cylinder 504, the rotating cylinder 505 vertically extending to the bottom of the housing 4, a second gear 503 that meshes with the first gear 502 is keyed to the position of the rotating cylinder 505 inside the housing 4, a connecting plate 506 is fixed to the lower end of the rotating cylinder 505, and a sprinkler head 510 is installed on the lower end of the connecting plate 506 through a rotating assembly. The monitoring instrument 2 contains a signal transmission and control unit consisting of a PLC and relays, as well as a motor driver. It receives the excessive dust signal from the dust detector on the top of the monitoring instrument 2 and sends a control command to drive the spray system in the spray box 901 and the first motor 501. The first motor 501 drives the first gear 502 to rotate, and the first gear 502 transmits to the second gear 503. The rotating drum 505 rotates with the second gear 503 on the outer wall of the fixed drum 504. The inner wall of the fixed drum 504 is fitted with the lamp post 1. The connecting plate 506 rotates with the rotating drum 505. The rotating component drives the spray head 510 to rotate with the connecting plate 506. The first motor 501 reverses every time it drives the spray head 510 to rotate 360° to prevent the hose 904 from getting tangled.

[0022] like Figure 9 As shown, the rotating assembly includes a fixed frame 507 fixed to the bottom of the connecting plate 506, a second motor 508 fixedly installed on one side of the fixed frame 507, a rotating frame 509 fixed to the output end of the second motor 508, and a spray head 510 fixed inside the rotating frame 509. Both the first motor 501 and the second motor 508 are Dongfang Motor BLH models. The operator drives the second motor 508 according to the dust suppression needs. The second motor 508 drives the rotating frame 509 to rotate, and the spray head 510 rotates with the rotating frame 509 to change the vertical angle of the spray.

[0023] like Figure 11 As shown, the water supply mechanism 9 includes a spray box 901, a water pipe 903 is connected to the spray box 901 by a flange, a hose 904 is connected to the end of the water pipe 903 away from the spray box 901 by a flange, and the end of the hose 904 away from the water pipe 903 is connected to the flange of the spray head 510. A protective shell 902 is fixed between the spray box 901 and the light pole 1. An installation groove is opened in the light pole 1, and the water pipe 903 is placed in the installation groove and the protective shell 902.

[0024] The sprinkler box 901 contains a water pump and a solenoid valve. The water pump input is connected to the municipal water pipe and is delivered to the sprinkler head 510 through the water pipe 903 and the hose 904 in sequence. The water pipe 903 is made of cast iron and the hose 904 is made of EPDM rubber. The protective shell 902 is fixed to the ground with bolts to the sprinkler box 901 and the bottom of the light pole 1.

[0025] Working principle: When the dust detector on the top of the monitor 2 detects excessive dust, the water pump in the spray box 901 draws water from the municipal water pipe and outputs it to the spray head 510. The first motor 501 drives the first gear 502 to rotate, and the first gear 502 transmits to the second gear 503. The rotating drum 505 rotates with the second gear 503 on the outer wall of the fixed drum 504. The inner wall of the fixed drum 504 is fitted with the lamp post 1. The connecting plate 506 rotates with the rotating drum 505. The rotating component drives the spray head 510 to rotate with the connecting plate 506. The operator drives the second motor 508 according to the dust suppression needs. The second motor 508 drives the rotating frame 509 to rotate, and the spray head 510 rotates with the rotating frame 509, changing the vertical angle of the spray. When the intelligent analysis box connected to the surveillance camera 12 detects a pedestrian or non-motorized vehicle in the real-time video captured by the surveillance camera 12, the microcontroller drives the output terminal of the third motor 701 to rotate via the motor driver. The third motor 701 drives the rotating shaft 702 fixedly connected to it to rotate. The third gear 703 on the rotating shaft 702 transmits the rotation to the adjacent rotating shaft 702. The first bevel gear 705 under the rotating shaft 702 rotates with the rotating shaft 702, the second bevel gear 707 rotates with the first bevel gear 705, the transmission shaft 706 rotates with the second bevel gear 707, and the third bevel gear 709 rotates with the transmission shaft 706. The third bevel gear 709 transmits the rotation to another third bevel gear 709 that meshes with it and is keyed to the adjacent transmission shaft 706. The adjacent drive shaft 706 rotates, and the second bevel gear 707 on the adjacent drive shaft 706 rotates accordingly and transmits power to the meshing first bevel gear 705, thereby realizing the rotation of the rotating shaft 702 in the adjacent mounting frame 6. In this way, all rotating shafts 702 can be rotated simultaneously. The connecting cylinder 704 rotates with the rotating shaft 702, and the fan-shaped baffle 710 rotates with the connecting cylinder 704 in opposite directions or relative to each other. During the rotation of the fan-shaped baffle 710, the shielding coverage area is increased, which shields the water mist or sunlight in the spray and improves the comfort of pedestrians. After no pedestrians are detected, the third motor 701 rotates in the opposite direction, so that the two fan-shaped baffles 710 located on the same mounting frame 6 are nearly overlapping, so that there is space between the fan-shaped baffles 710 on the two adjacent mounting frames 6 for water mist to fall and suppress dust.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
