[0001] This utility model relates to the field of solar power generation technology, specifically to a solar-powered flashing arrow light. Background Technology

[0002] With the rapid development of the expressway industry, the importance of expressway maintenance work is becoming increasingly prominent. Expressway maintenance workers belong to the fifth category of high-risk industries. It is generally recognized that they carry out maintenance work on expressways that are normally open to traffic. The maintenance work cannot be interrupted regardless of the season, and the working environment is relatively harsh.

[0003] Existing arrow lights require battery power. However, batteries are bulky and inconvenient to carry, provide short-term power, and have low voltage, making them unsuitable for powering multiple arrow lights simultaneously. If multiple arrow lights need to be powered at the same time, the number of batteries must be increased, which would significantly increase costs. Summary of the Invention

[0007] Furthermore, a circuit board is installed on the left side of the arrow light, and a controller is installed on the circuit board. An inverter and a load are installed on the right side of the circuit board. The controller is connected to the cylindrical lithium battery, solar panel, and inverter through wires, and the inverter is connected to the load through wires, forming a control device.

[0008] Furthermore, a square mounting box is provided on the upper right side of the inner wall of the conical sign. A strobe controller is installed inside the square mounting box.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 As shown in the figure, a solar-powered flashing arrow light according to this specific embodiment includes a solar panel 1, on which a support column 2 is installed; the support column 2 is inserted into a square hole on the top surface of a cone-shaped marker 4; a clamp 5 is fitted onto the cone-shaped marker and installed on the back of the arrow light 3; a control device 6 is installed at the bottom inside the cone-shaped marker 4, and the control device 6 is connected to the solar panel 1 and the arrow light 3 respectively through wires.

[0020] Furthermore, the support column 2 is a cylindrical body, and a cylindrical lithium battery 65 is installed inside the cylindrical body. In this design, the cylindrical body is hollow, and the bottom end of the cylindrical body is threaded. A bottom box threaded cover is screwed onto the threaded opening of the cylindrical body, and several wire holes are opened on the bottom box threaded cover. Strip-shaped heat dissipation holes are opened on the side of the cylindrical body.

[0021] Furthermore, a circuit board 62 is installed on the left side of the arrow light 3, and a controller 61 is installed on the circuit board 62. An inverter 63 and a load 64 are installed on the right side of the circuit board 62. The controller 61 is connected to the cylindrical lithium battery 65, the solar panel 1, and the inverter 63 through wires respectively. The inverter 63 is connected to the load 64 through wires, forming a control device 6.

[0022] Furthermore, a square mounting box 9 is provided on the upper right side of the inner wall of the conical marker 4. A strobe controller 7 is installed inside the square mounting box 9. The strobe controller 7 is connected to the cylindrical lithium battery 65 through wires. The strobe controller 7 is connected to the positive and negative terminals of several LED light strips 8 installed around the back of the arrow light 3 through several wires.

[0023] like Figure 2 The diagram shows the connection topology of the components of control device 6 in this design. Controller 61 is a solar power controller, a commercially available product. Its installation is as follows: Of the six terminals of the solar power controller, the left positive and negative terminals are connected to the positive and negative terminals of the solar panel 1; the middle positive and negative terminals are connected to the positive and negative terminals of the cylindrical lithium battery 65; and the right positive and negative terminals are connected to the positive and negative terminals of the arrow light 3.

[0024] The working principle of this utility model is explained in detail below: This design includes a solar panel, a support column, an arrow light, and connecting wires. The support column is fixed to the solar panel base with screws, and then inserted into the hole above the cone-shaped marker. A clamp is fixed to the back of the arrow light and fitted onto the tip of the cone-shaped marker.

[0025] This invention features a simple structure and is easy to carry. It uses a solar panel and a cylindrical lithium battery for power, saving the cost of purchasing high-power batteries and the cost of charging them.

[0026] Each high-power battery costs approximately 1500 yuan. If multiple light groups are connected via wiring, to ensure the lighting effect, only 3 groups (6 lights in total) and 3 controllers can be connected simultaneously. The total cost of each group of 3 lights, controllers, and batteries is approximately 2200 yuan. To ensure the warning effect, at least 30 lights in 5 groups are needed for each installation, with a total cost of 11000 yuan per month.

[0027] The improved solar panel is connected to the arrow light via a plug-in method. Each light can be controlled by a switch individually, or a switch can be installed directly on the solar panel and the light body to enable multiple light groups to be connected in series and parallel and turn on and flash simultaneously.

[0028] like Figure 3 As shown, this design integrates the chip of the strobe controller 7 into the lamp's circuit board, enabling the strobe light to flash immediately upon power-up. It incorporates a 12V-24V universal solar panel and a built-in cylindrical lithium battery, charging via the solar panel during the day and using the lithium battery at night to ensure continuous operation. The strobe controller 7 is installed in a square mounting box 9 on the upper right side of the conical sign's inner wall. The square mounting box has wire holes and mounting holes for easy fixing of the strobe controller 7 and for wiring.

[0029] Each light costs approximately 300 yuan, and 30 lights are installed per installation, with a total cost of approximately 9,000 yuan. Specifically, the strobe controller 7 is powered by a cylindrical lithium battery 65. Several negative terminals of the strobe controller 7 are connected to the negative terminals of several LED strips, and the positive terminals of the strobe controller 7 are connected to the positive terminals of several LED strips 8 using wires, thus controlling the strobe effect. Several LED strips 8 can be installed on arrow lights 3, which have wire holes fitted with waterproof sealing rings for easy wiring and waterproof sealing. The chips and circuit boards mentioned above are easily understood by those skilled in the art and are therefore considered existing technology.

[0030] like Figure 4The diagram shows the control circuit schematic on the circuit board of this design. The U1 chip (model MC34063) has pins 1 and 8 connected in parallel across inductor L, pins 2 and 4 grounded, and pin 7 connected in parallel with inductor L. Load resistor R3 is connected in parallel between inductor L and load R4. Capacitor C3 is connected in series with resistor R2, capacitor C2gn and diode D1 are connected in series, and diode D and resistor D are connected in parallel across inductor L. In this design, the MC34063 (U1 chip) is a microcontroller (monolithic integrated circuit) and a control circuit that includes a DC / DC converter. It mainly consists of a temperature-compensated voltage source, a duty cycle-controlled oscillator, a driver, a comparator, and an RS flip-flop with a high-current output switching circuit. This power supply can be constructed using very few switching components, including a step-down converter, a step-up converter, and a voltage inverting circuit. Compared to linear regulated power supplies, it is more efficient, and its efficiency does not decrease even with large input-output voltage drops. It also requires no large heatsink, is small in size, and is suitable for use in microprocessor or microcontroller-based systems. It can operate within an input voltage range of 2.5-40Vr, and the output voltage is adjustable within a range of 1.25-40V. It features low quiescent current and limits short-circuit current.

[0031] Pin 3 of the MC34063 chip is the timing capacitor interface, where an external constant capacitor is connected. The oscillator continuously charges and discharges the capacitor under the action of a constant current source, thereby generating an oscillation waveform. It also has a charge limiting function, which is achieved by detecting the voltage drop between pins 6 and 7. When the voltage between pins 6 and 7 exceeds 300mV, the chip will activate the overcurrent protection function, and the oscillator will quickly charge the timing capacitor, thereby reducing the conduction time of the output transistor and extending its off time.

[0032] When constructing a highway, this design requires setting up the work area in advance, then fixing the arrow lights and solar panels to the tips of the cones, and turning on the switches.

[0033] To enhance the safety of maintenance workers, this design takes a multi-faceted approach. The existing arrow lights are vehicle-mounted arrow lights, installed on the top or rear of vehicles, powered by the vehicle's battery, and flashed by a controller, effectively warning passing vehicles.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
