Technical Field
[0001] This utility model relates to the field of solar LED street light technology, and more specifically, to an energy-saving and environmentally friendly solar LED street light. Background Technology
[0002] Currently, solar LED streetlights are widely used in the field of road lighting. They use solar panels to convert light energy into electrical energy to provide the power required for LED lighting, and have advantages such as energy saving, environmental protection, and convenient installation.
[0003] However, the power generation efficiency of solar panels is closely related to the angle of sunlight, and the optimal tilt angle needs to be adjusted according to the local latitude (e.g., in the Northern Hemisphere, it is usually ±15°). Traditional fixed-tilt designs cannot adapt to seasonal changes. The solar altitude angle is high in summer and low in winter, which significantly reduces the amount of solar radiation received by the solar panels in winter, resulting in a 30%-50% reduction in power generation. This severely impacts the lighting effect and battery life of solar LED streetlights in winter. To improve the power generation efficiency of solar panels, some devices capable of adjusting the tilt angle have emerged in existing technologies. However, these devices lack a structure that prevents automatic reset in the event of a power outage, causing the solar panel to remain fixed in position after adjustment, reducing daily sunlight exposure time and affecting power generation, making it difficult to meet practical application needs. Therefore, we propose an energy-saving and environmentally friendly solar LED streetlight. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an energy-saving and environmentally friendly solar LED street light to solve the technical problem that the solar panels with angle adjustment devices lack an automatic reset structure when they malfunction, which affects the daily sunlight exposure of the solar panels.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an energy-saving and environmentally friendly solar LED street light, comprising a street light body consisting of a light pole, an LED light, an adjustment device, and a solar panel. The adjustment device includes a fixing frame, an adjustment rod rotatably mounted between opposing side plates of the fixing frame, angle adjustment frames fixedly connected to both ends of the adjustment rod, a mounting frame for fixing the solar panel fixedly mounted on the top of the angle adjustment frame, an extension plate fixedly provided on one side of the bottom of the fixing frame, and a reduction motor connected to the end of the adjustment rod fixedly mounted on the top of the extension plate.
[0006] Several connectors are fixedly installed on the wall of the adjusting rod, and several fixed seats corresponding to the end positions of the connectors are fixedly installed on the top side of the fixing frame. Each connector is fixedly connected to the fixed seat and is also a tension member used for resetting.
[0007] This invention utilizes a tension component to ensure that the adjusting rod remains stable after angle adjustment thanks to the tension of an elastic plate, preventing angle deviation of the solar panel due to external forces such as wind. Simultaneously, when readjustment is required, the tension component assists the adjusting rod in quickly resetting, ensuring smooth and reliable angle adjustment of the solar panel. Furthermore, the automatic reset function allows the solar panel to automatically reset in the event of a geared motor malfunction, thereby reducing energy loss caused by angle deviation and maintaining stable power generation.
[0008] Preferably, the connector includes a collar, a connecting block integrally formed on the outer wall of the collar, and a connecting groove through the side wall of the connecting block.
[0009] Preferably, the tension member includes an elastic plate passing through the connecting groove, and a limiting block that fits against the surface of the connecting block is fixedly provided at the end of the elastic plate away from the fixed seat. Two reinforcing plates for improving strength are fixedly provided on the side wall of the elastic plate inside the fixed seat. A limiting hole is opened through between the reinforcing plate and the elastic plate. A limiting pin that passes through the limiting hole is threadedly connected to the side wall of the fixed seat.
[0010] Preferably, both ends of the adjusting rod are fixedly provided with limiting circular plates that fit against the side of the fixing frame. The limiting circular plates are provided with C-shaped grooves on their walls. The two side plates of the fixing frame are fixedly provided with positioning components located inside the C-shaped grooves.
[0011] Preferably, the positioning component includes a fixed circular block with deformation characteristics, and a locking block symmetrical to the center is integrally formed on the outer wall of the fixed circular block. The opposing surfaces of one end of the C-shaped groove are provided with locking grooves that engage with the locking block.
[0012] Preferably, the fixed circular block has an elastic cavity inside, and an elliptical elastic support block is fixedly disposed between the elastic cavity and the inner wall of the corresponding position of the two side locking blocks, and the elastic support block is made of rubber.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of a tension component, enables the adjusting rod to maintain a stable state after angle adjustment with the help of the elastic plate, preventing the solar panel angle from shifting due to external forces such as wind. Simultaneously, when readjustment is required, the tension component assists the adjusting rod in quickly resetting, ensuring the smoothness and reliability of solar panel angle adjustment. Furthermore, the automatic reset function allows the solar panel to automatically reset in the event of a geared motor malfunction, thereby reducing energy loss caused by angle deviation and maintaining stable power generation.
[0015] 2. This utility model also strengthens the initial position limiting strength of the solar panel through the structural design of the limiting circular plates, C-shaped grooves, and positioning components at both ends of the adjusting rod. The interlocking of the positioning grooves and the positioning blocks enhances this strength. Furthermore, the cooperation between the elastic cavity and the elastic block ensures that the surface of the C-shaped groove of the limiting circular plate closely adheres to the surface of the positioning block during movement. This increases resistance when the pulling component pulls the adjusting rod to reverse and reset, slowing down the reset speed and reducing the impact of the vibration generated by the reset collision on the solar panel. This improves the safety of the structural fit and further enhances the stability of the solar panel position in the event of a geared motor failure, reducing the influence of the external environment on the solar panel's position under sunlight.

[0023] like Figures 1 to 6As shown, this utility model relates to an energy-saving and environmentally friendly solar LED street light, comprising a street light body consisting of a light pole 1, an LED light 2, an adjustment device 3, and a solar panel 4. The adjustment device 3 includes a fixing frame 301, with an adjustment rod 302 rotatably mounted between opposing side plates of the fixing frame 301. Angle adjustment frames 303 are fixedly connected to both ends of the adjustment rod 302. A mounting frame 304 for fixing the solar panel 4 is fixedly mounted on the top of the angle adjustment frame 303. An extension plate 305 is fixedly provided on one side of the bottom of the fixing frame 301, and a reduction motor 5 connected to the end of the adjustment rod 302 is fixedly mounted on the top of the extension plate 305. The bottom of the fixing frame 301 is sleeved on the wall of the light pole 1 and fixed in position by bolts. The cooperation between the adjustment rod 302 and the reduction motor 5 can control the angle adjustment frame 303 to rotate and adjust the angle, thereby realizing the angle adjustment of the solar panel 4 on the mounting frame 304 to irradiate sunlight and extending the duration of illumination.
[0024] Several connectors 6 are fixedly installed on the wall of the adjusting rod 302. Several fixed seats 306 corresponding to the end positions of the connectors 6 are fixedly installed on the top side of the fixing frame 301. Each connector 6 is fixedly connected to the fixed seat 306 and is also used for resetting. The connectors 6 rotate synchronously with the adjusting rod 302, which can stretch the connected tension 7 to deform and elongate, thereby forming a pull-back force. In this way, when the reduction motor 5 fails to work, the force of the tension 7 can be used to rotate the adjusting rod 302 back to its original position, so that the solar panel 4 can maintain a stable position for illumination.
[0025] In this embodiment of the present invention, the connector 6 includes a collar 601, on the outer wall of which a connecting block 602 is integrally formed. A connecting groove 603 is formed through the side wall of the connecting block 602. The tension member 7 includes an elastic plate 701 passing through the connecting groove 603. A limiting block 702 that fits against the surface of the connecting block 602 is fixedly provided at the end of the elastic plate 701 away from the fixing seat 306. Two reinforcing plates 703 for increasing strength are fixedly provided on the side wall of the elastic plate 701 inside the fixing seat 306. A limiting hole 704 is formed through the reinforcing plate 703 and the elastic plate 701. A threaded connection is made to the side wall of the fixing seat 306. The limiting pin 307 passes through the limiting hole 704; the connecting groove 603 facilitates the passage of the elastic plate 701; the limiting block 702 at the end of the elastic plate 701 restricts the connection position; the reinforcing plate 703 at the joint position of the elastic plate 701 and the fixing seat 306 can improve the strength. In this way, when the limiting pin 307 passes through the limiting hole 704 and is fixed in position, the damage caused by tensile deformation can be reduced, and the structural fit strength can be improved. At the same time, the top of the fixing frame 301 is also provided with a protective cover structure to shield the tensile component 7, which can reduce the impact of the external environment on the quality of the tensile component 7, improve the durability of the structure, and maintain a stable pull-back limiting effect.
[0026] In this embodiment of the utility model, limiting circular plates 8 that fit against the sides of the fixing frame 301 are fixedly provided on the outer walls of both ends of the adjusting rod 302. C-shaped grooves 801 are formed on the plate walls of the limiting circular plates 8. Positioning members 9 located inside the C-shaped grooves 801 are fixedly provided on the opposite sides of the two plates of the fixing frame 301. The positioning members 9 include fixing circular blocks 901 with deformation characteristics. A locking block 902 symmetrical to the center is integrally formed on the outer wall of the fixing circular block 901. A locking groove 802 that engages with the locking block 902 is formed on the facing surfaces of one end of the C-shaped groove 801. The design can further enhance the limiting effect of the installation position of the adjusting rod 302. The cooperation between the C-shaped groove 801 and the positioning part 9 can increase the resistance of the rotation of the adjusting rod 302, which can reduce the rotation speed during reset, thereby reducing the impact force on the solar panel 4 during reset and enhancing the protection of the solar panel 4. At the same time, the combination of the locking block 902 and the locking groove 802 can improve the initial limiting strength. The pulling force of the pulling part 7 can further improve the limiting effect of the initial position, making it less susceptible to the influence of external wind speed and causing the solar panel 4 to shake, thus further improving the stability of the position.
[0027] In an embodiment of this utility model, an elastic cavity 903 is provided inside the fixed circular block 901. An elliptical elastic support block 904 is fixedly provided between the elastic cavity 903 and the inner wall of the corresponding position of the two side locking blocks 902, and the elastic support block 904 is made of rubber. The design of the elastic cavity 903 and the elastic support block 904 can improve the deformation effect, making it easier for the locking block 902 to separate from the locking groove 802 during the rotation of the limiting circular plate 8, and to automatically engage and limit when the position is aligned.
[0028] Working Principle: This embodiment provides an energy-saving and environmentally friendly solar LED street light. During the rotation of the adjusting rod 302 controlled by the geared motor 5, several connecting parts 6 fixedly installed on the rod wall also rotate. Each connecting part 6 includes a collar 601, a connecting block 602, and a connecting groove 603. The collar 601 is fixedly fitted onto the adjusting rod 302, and the connecting groove 603 on the connecting block 602 is used to connect a tension member 7. The elastic plate 701 of the tension member 7 passes through the connecting groove 603, and a limiting block 702 at one end is in contact with the surface of the connecting block 602 to prevent the elastic plate 701 from dislodging from the connecting groove 603. When the adjusting rod 302 rotates to adjust the angle of the solar panel 4, the connecting parts 6 pull the elastic plate 701, causing the elastic plate 701 to undergo elastic deformation and generate tension. Once the reduction motor 5 stops working due to a malfunction, the elastic restoring force of the elastic plate 701 will pull the connecting piece 6, which will then cause the adjusting rod 302 to tend to rotate and reset, allowing the solar panel 4 to return to its initial angle position. This avoids the problem of the solar panel 4 being unable to return to its original position due to a malfunction. At the same time, the two reinforcing plates 703 fixedly installed on the side wall of the elastic plate 701 inside the fixed base 306 can improve the strength of the elastic plate 701. By passing the limiting pin 307 through the limiting hole 704, the elastic plate 701 can be firmly installed in the fixed base 306, ensuring the connection reliability of the tensioning member 7. The limiting circular plates 8 fixedly installed on the outer walls of both ends of the adjusting rod 302 have C-shaped grooves 801 on their walls, and the positioning members 9 fixedly installed on the two sides of the fixed frame 301 opposite to each other are located inside the C-shaped grooves 801. The positioning component 9 includes a fixed circular block 901 and a locking block 902. The fixed circular block 901 has an elastic cavity 903 inside, and an elliptical elastic support block 904 is fixedly installed between the elastic cavity 903 and the inner wall of the locking blocks 902 on both sides at corresponding positions. When the adjusting rod 302 rotates, the limiting circular plate 8 rotates accordingly, and the C-shaped groove 801 moves along the positioning component 9, causing the fixed circular block 901 to be compressed and deformed, achieving a tight fit and increasing the resistance to movement. This slows down the rotation speed when the pulling component 7 pulls the adjusting rod 302 back to its original position. At the same time, when the locking block 902 re-engages with the locking groove 802, it strengthens the limiting strength of the pulling component 7 on the position of the solar panel 4 irradiated by sunlight, further improving the stability of the position of the solar panel 4 when the adjusting device 3 malfunctions.
