Description

Technical Field

[0001] This utility model relates to the field of signage technology, and in particular to a photovoltaic-powered smart signage. Background Technology

[0002] Currently, existing signage (such as patent publication number: CN221766258U) discloses a signage that uses a two-way screw and nut threaded engagement to drive the insertion block to move. The insertion block and insertion hole are snapped together to facilitate the installation of the signage body on the column. The snap-fit ​​installation of the signage body optimizes its ease of replacement. At the same time, when replacing the signage body, it is not necessary to replace the column and mounting base, thus reducing the corresponding costs.

[0003] In the aforementioned patents, many signs need to be installed in the wild or in mountainous areas, often far from the city power grid. If mains power is used, long-distance cables need to be laid, which not only increases construction costs but also makes later maintenance more difficult. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a photovoltaic-powered smart signboard, solving the technical problem that many signs need to be installed in the wild or mountainous areas, often far from the urban power grid. If mains power is used, long-distance cables need to be laid, which not only increases construction costs but also makes subsequent maintenance more difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A photovoltaic-powered smart signboard includes a bracket and a signboard body. The bracket has multiple bolts on its side end and also includes;

[0007] A photovoltaic module is mounted on the top of a support frame. The photovoltaic module includes a storage rack, a wiring harness, and a photovoltaic panel. The top of the photovoltaic panel is connected to the storage rack via a support shaft, and the end of the wiring harness is connected to a battery and an inverter.

[0008] Preferably, a rotating lead screw is rotatably mounted inside the bracket, and a sliding plate is rotatably mounted on the surface of the rotating lead screw, wherein the thread helix angle of the sliding plate and the rotating lead screw is less than the friction angle;

[0009] A pivot seat is fixedly installed at the top of the sliding plate, and a deflection cantilever is rotatably installed inside the pivot seat. The top of the deflection cantilever is rotatably connected to the inner side of the photovoltaic panel.

[0010] Preferably, a combiner box is fixedly installed on the top of the photovoltaic panel, and multiple nozzles are provided on the bottom surface of the combiner box;

[0011] A pipe is fixedly installed on the side end of the photovoltaic panel, and the end of the pipe is connected to a sealed tank.

[0012] Multiple photoresistors are fixedly installed on the surface of the photovoltaic panel, and the multiple photoresistors are all linearly arranged.

[0013] Compared with the prior art, the present invention has the following beneficial effects;

[0014] In this invention, multiple photoresistors arranged linearly on the surface of the photovoltaic panel move upwards on the sliding plate, enabling the photovoltaic panel to rotate around the top support axis. The tilt angle can be flexibly adjusted. The photovoltaic panel converts light energy into direct current, which is then stored in a battery via a wire harness. This achieves the effective collection, storage, and utilization of clean energy (solar energy) to power electrical components such as the LED beads on the front of the sign.

[0015] In this invention, because the helix angle of the rotating lead screw and the sliding plate is less than the friction angle, the two have self-locking characteristics. After the photovoltaic panel angle is adjusted, it can stably maintain the angle. When the photovoltaic panel rotates, the top junction box rotates synchronously. The cleaning agent is sprayed from the nozzle onto the surface of the photovoltaic panel through the pipe and the junction box, which can automatically clean the dust on the surface of the photovoltaic panel at regular intervals, avoiding the long-term coverage of dust from affecting the absorption of light energy.

[0022] This application provides a photovoltaic-powered smart signboard, which effectively solves the problem that many signs need to be installed in the wild or mountainous areas, far from the urban power grid. If mains power is used, long-distance cables need to be laid, which not only increases construction costs but also makes later maintenance more difficult. Multiple photoresistors linearly arranged on the surface of the photovoltaic panel slide up, realizing the rotation of the photovoltaic panel around the top support axis, which can flexibly adjust the tilt angle. The photovoltaic panel converts light energy into direct current, which is stored in the battery through the wire harness, realizing the effective collection, storage and utilization of clean energy (solar energy) to power the electrical components such as the LED beads on the front of the signboard.

[0023] Example

[0024] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that many signs need to be installed in the wild or mountainous areas, often far from the urban power grid. If mains power is used, long-distance cables need to be laid, which not only increases construction costs but also makes later maintenance more difficult. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the present invention provides a photovoltaic power supply smart sign, including a bracket 11 and a sign body 12. The side end of the bracket 11 is provided with multiple bolts. The bracket 11 and the photovoltaic panel 15 are both set on the back of the sign body 12. The front of the sign body 12 displays various indicator information, and different LED beads are set on the front of the sign body 12.

[0026] The photovoltaic module is mounted on the top of the support frame 11. The photovoltaic module includes a storage rack 13, a wiring harness 14, and a photovoltaic panel 15. The top of the photovoltaic panel 15 is connected to the storage rack 13 via a support shaft. The end of the wiring harness 14 is connected to the battery and the inverter. The angle is adjusted by deflecting the photovoltaic panel 15. The photovoltaic panel 15 directly converts the absorbed solar energy into direct current through the photovoltaic effect. The power is then transmitted to the battery through the wiring harness 14 and stored in the form of chemical energy. This also prevents the battery from being overcharged or over-discharged. When electricity is needed, the battery releases the stored electrical energy.

[0027] A rotating lead screw 19 is rotatably mounted inside the bracket 11, and a sliding plate 18 is rotatably mounted on the surface of the rotating lead screw 19. The thread helix angle of the sliding plate 18 and the rotating lead screw 19 is less than the friction angle. A micro motor is installed inside the bracket 11. By rotating the rotating lead screw 19 in the forward direction, the rotating lead screw 19 rotates inside the bracket 11. The rotating lead screw 19 drives the sliding plate 18 to slide upward inside the bracket 11. The sliding plate 18 slides vertically along the inside of the bracket 11. When the rotating lead screw 19 stops rotating, the sliding plate 18 and the rotating lead screw 19 can lock themselves.

[0028] A pivot seat 17 is fixedly installed at the top of the sliding plate 18. A deflection cantilever 16 is rotatably installed inside the pivot seat 17. The top of the deflection cantilever 16 is rotatably connected to the inner side of the photovoltaic panel 15. As the rotating screw 19 generates an upward thrust on the pivot seat 17, the deflection cantilever 16 rotates inside the pivot seat 17. At the same time, the top of the deflection cantilever 16 generates a thrust on the lower half of the photovoltaic panel 15, causing the photovoltaic panel 15 to rotate around the top and adjust the tilt angle of the photovoltaic panel 15.

[0029] A junction box 21 is fixedly installed on the top of the photovoltaic panel 15. Multiple nozzles 22 are provided on the bottom surface of the junction box 21. When the photovoltaic panel 15 rotates, it drives the junction box 21 to rotate synchronously. Cleaning agent is delivered into the junction box 21 through the pipe 23 at regular intervals. Under the push of high pressure gas, the cleaning agent is sprayed onto the surface of the photovoltaic panel 15 through the multiple nozzles 22 to clean the dust on the surface of the photovoltaic panel 15.

[0030] A pipe 23 is fixedly installed on the side end of the photovoltaic panel 15. The end of the pipe 23 is connected to a sealed container. A solenoid valve is installed at the top of the sealed container. By opening the solenoid valve at timed intervals, the cleaning agent inside the sealed container is delivered into the pipe 23. High-pressure gas pushes the cleaning agent into the inside of the junction box 21.

[0031] Multiple photoresistors 24 are fixedly installed on the surface of the photovoltaic panel 15. The multiple photoresistors 24 are arranged linearly. The resistance of the photoresistors 24 changes with the light intensity. The stronger the light, the smaller the resistance. The photoresistors 24 convert the resistance change caused by the light into a voltage change. The electrical signal is transmitted to the control circuit to determine the intensity and direction of sunlight.

[0032] Working principle:

[0033] In the first step, the micro motor inside the bracket 11 drives the rotating screw 19 to rotate in the forward direction. Because the rotating screw 19 is threadedly engaged with the sliding plate 18 (and the thread helix angle is less than the friction angle), when the rotating screw 19 rotates, it drives the sliding plate 18 to slide upward inside the bracket 11. After the rotation stops, the two maintain their position due to the self-locking characteristic. The sliding plate 18 moves upward, and its top pivot seat 17 pushes the deflection cantilever 16 to rotate. The top of the deflection cantilever 16 applies force to the lower half of the photovoltaic panel 15, causing the photovoltaic panel 15 to rotate around the top support axis (the axis connected to the storage rack 13), adjusting the tilt angle to adapt to different light angles and improve the light energy absorption efficiency.

[0034] The photovoltaic panel 15 converts the absorbed solar energy into direct current through the photovoltaic effect, which is transmitted through the wire harness 14. The electrical energy is stored in the battery in the form of chemical energy. The inverter can adapt to different power demand and convert the form of electrical energy. At the same time, the related circuit can prevent the battery from being overcharged or over-discharged, ensuring the safety and stability of electrical energy storage.

[0035] In the second step, when the photovoltaic panel 15 rotates, the top junction box 21 rotates synchronously. The solenoid valve at the top of the sealed tank opens at a time. Under the pressure of the gas, the cleaning agent enters the junction box 21 through the pipe 23, and then is sprayed onto the surface of the photovoltaic panel 15 through multiple nozzles 22 on the bottom surface to clean the dust and maintain the photoelectric conversion efficiency of the photovoltaic panel 15. Multiple photoresistors 24 linearly arranged on the surface of the photovoltaic panel 15 change their resistance values ​​with the light intensity, converting the light conditions into voltage signals and transmitting them to the control circuit. This can be used to determine the intensity and direction of sunlight, and to assist in controlling the angle adjustment of the photovoltaic panel 15, the cleaning timing, and other operations, making the photovoltaic power supply system for the sign more intelligent and efficient.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
