Description

Technical Field

[0001] This application relates to the field of streetlights, specifically to a smart LED streetlight based on the Internet of Things. Background Technology

[0002] Streetlights are common lighting facilities in cities. With the advancement of technology, modern urban management is no longer just about lighting up the city, but also involves the management of complex urban information, such as video surveillance, environmental parameter monitoring, remote control, and the Internet of Things. Therefore, in addition to meeting basic lighting needs, existing streetlights are being given many additional functions, and the concept of smart streetlights has emerged. As a result, streetlights, as widely distributed lighting facilities, are participating more in the management of smart cities. However, compared with ordinary streetlights, smart streetlights involve more complex components, so the cost and frequency of maintenance are higher. On the other hand, since streetlights are generally tall, daily maintenance requires special maintenance vehicles with ladder functions, making maintenance more inconvenient. Parking on urban roads also hinders daily traffic. Summary of the Invention

[0003] Purpose of the invention: In order to solve the above problems, this application discloses a smart LED street light based on the Internet of Things.

[0004] Technical Solution: A smart LED street light based on the Internet of Things includes a base plate, a light pole fixedly connected to the base plate, a light head bracket connected to the light pole, and an LED light head fixedly connected to the light head bracket. An electric vehicle charging station is also installed on the base plate. A display screen unit is installed on the side wall of the light pole. An L-shaped pole and a vertical pole are installed at the display screen unit. A video monitor is installed at the L-shaped pole. A sensor mounting plate is fixed to the top of the vertical pole. A mounting box is installed at the sensor mounting plate. A wireless communication unit is installed inside the mounting box. A connection unit connects the L-shaped pole and the vertical pole.

[0005] Furthermore, the connecting unit has two components, each including a circular ring and a T-shaped bracket. The circular ring is fixed to the vertical rod, and the T-shaped bracket is fixed to the L-shaped rod.

[0006] Furthermore, a first guide rail and a first limiting block are fixed to the side wall of the lamp post, and a first sliding groove that mates with the first guide rail is provided on the side of the display unit. The cross-sections of the first guide rail and the first sliding groove are both trapezoidal. A fixing frame is also fixed to the side wall of the lamp post, and a sleeve is fixed to the fixing frame. A first pin is installed inside the sleeve, and a spring is connected between the end of the first pin and the closed end of the sleeve. A connecting block is fixed to the top of the display unit, and a first insertion hole that can be inserted by the first pin is provided at the connecting block. When the display unit is in the lowest position, the display unit abuts against the first limiting block.

[0007] Furthermore, one end of the spring is connected to the end of the first pin, and the other end is connected to the closed end of the sleeve.

[0008] Furthermore, a second guide rail and a second limiting block are fixed to the side wall of the lamp post. The connecting block also has a second insertion hole. A through groove exists between the first insertion hole and the top of the connecting block. A movable block with a second sliding groove is installed on the second guide rail. The cross-sections of both the second guide rail and the second sliding groove are trapezoidal. A movable plate is fixed to the movable block. A drive unit is connected to the movable plate via a cylinder. The drive unit includes a movable seat and a sliding sleeve. The sliding sleeve has a slider that can be inserted into and slide within the sleeve from its bottom end. A winding unit and a mechanism for... are fixed to the top of the movable seat. A drive motor drives the winding unit. A crossbar is fixed at the slider. A pull rope connects the winding unit and the crossbar. The movable seat has a through hole through which the pull rope passes. An L-shaped bracket is fixed to the side of the sliding sleeve. A push rod is fixed to the L-shaped bracket. A push block is fixed to the end of the push rod. The push rod can pass through the through groove of the connecting block. A second pin that can be inserted into a second insertion hole is also fixed at the slider. A limit seat is installed at the base plate. The movable block is also connected to the top end of the multi-stage hydraulic telescopic rod. The bottom end of the multi-stage hydraulic telescopic rod can be installed at the limit seat.

[0009] Furthermore, when the movable block is at its highest position, it abuts against the second limiting block; when the multi-stage hydraulic telescopic rod is in its shortest state, the movable block can detach from the bottom of the second slide rail; when the movable block abuts against the second limiting block, the first pin is inserted into the first insertion hole, and the cylinder is in its shortest state, the second pin faces the second insertion hole, and the push block faces the end of the first pin.

[0010] Furthermore, both the ends of the first and second pins are chamfered, and there are two cylinders, one of which is connected to the movable seat and the other is connected to the sliding sleeve.

[0011] Using two cylinders makes the drive of the sliding sleeve and moving seat more stable and reliable.

[0012] Furthermore, the slider is a vertical strip slider with a chamfer at the top, and the top of the slider can abut against the lower surface of the movable seat.

[0013] Thus, the movable seat limits the upward movement of the slider, and the top of the slider has a chamfer, making it easier for the slider to be inserted into the sleeve from the bottom.

[0014] Furthermore, the sliding sleeve includes a sliding sleeve body with a U-shaped cross-section and two strip-shaped limiting plates connected to the sliding sleeve body; when the slider is inserted into the sliding sleeve, the sliding sleeve body and the two strip-shaped limiting plates surround the slider.

[0015] Thus, the sliding sleeve limits the slider. When the slider is inserted into the sliding sleeve and the top of the slider abuts against the movable seat, the extension of the cylinder drives the slider more stably.

[0016] Furthermore, the limiting seat has a mounting groove, and the bottom end of the multi-stage hydraulic telescopic rod can be installed in the mounting groove.

[0017] Furthermore, a camera, controller, and Bluetooth device are installed at the movable seat.

[0018] By capturing images through a camera and transmitting them to the handheld terminal of maintenance personnel via Bluetooth, the operation screen at the mobile seat can be obtained, making the operation more controllable and convenient for the operator.

[0019] Beneficial effects: The streetlights of this application can provide more complex functions, thus enabling more diversified applications in smart cities and their management. They have functions such as video surveillance, information display, wireless communication, environmental monitoring, and communication relay. Furthermore, when maintenance is required, the functional modules can be proactively lowered to perform maintenance on the ground, resulting in lower maintenance costs and greater efficiency and convenience.

The sensor mounting plate can be used to install various types of sensors, such as temperature sensors, humidity sensors, and pollutant detection sensors, and the mounting box can also be used to install various necessary electronic devices.

[0030] Another major advantage of this application is that these sensing devices and video surveillance equipment are all installed above the display unit. Under normal circumstances, the first pin is inserted into the first socket of the connecting block, and the display unit is stably fixed at a high position by the limiting action of the first pin and the first guide rail. When a malfunction occurs and repair is needed, simply install the bottom end of the multi-stage hydraulic telescopic rod into the limiting seat, causing the multi-stage hydraulic telescopic rod to gradually extend. The second slide groove of the movable block and the second guide rail engage, and then the movable block continues to rise until it abuts against the second limiting block. Then the cylinder extends, the second pin is inserted into the second socket, and the push block pushes the first pin to shorten. Figure 3 As shown, the winding mechanism then releases the rope, the display unit descends, and the push rod passes through the through slot, lowering the display unit to the first limit block for maintenance at a lower position. After maintenance, the winding device retracts the rope until the slider rises to its highest position (at which point the slider abuts against the movable seat), the cylinder shortens, the first pin re-inserts into the first socket, and the second pin is pulled out of the socket. This allows for convenient and efficient maintenance, reducing urban management costs.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
