Description
Technical Field
[0001] This invention belongs to the field of solar panel technology, and in particular relates to a solar street light with a solar panel having a spin function. Background Technology
[0002] With the popularization of solar energy technology, solar streetlights have become an important solution for urban lighting and power supply in remote areas. Traditional solar streetlights typically fix the solar panels to the top of the pole, and their orientation and tilt angle remain unchanged after being set at the time of installation.
[0003] However, this fixed installation has significant drawbacks. Because the sun's position in the sky changes daily, fixed-angle solar panels cannot always remain perpendicular to sunlight, resulting in a much lower amount of solar radiation received than ideal. Especially during the day, the sun's azimuth angle changes by more than 180°, making stationary solar panels extremely inefficient in the morning and afternoon. This directly leads to a decrease in energy collection efficiency, typically estimated to be over 30% overall. To ensure nighttime lighting, larger capacity batteries and larger solar panels are often required, which not only increases the initial cost of the equipment and material consumption but also contradicts the original intention of green energy conservation.
[0004] To overcome these shortcomings, several solutions have been proposed in existing technologies to enable solar panels to rotate and track the sun. The current mainstream approach is the photoelectric tracking system, which uses sensors to detect the sun's position and a motor to drive the solar panel's rotation. While this type of system can effectively improve power generation efficiency, it has inherent drawbacks: firstly, it relies heavily on motors, sensors, and a complex control system, resulting in a complex structure, high manufacturing costs, and relatively low reliability.
[0005] In addition, there are some purely mechanical tracking solutions, such as those using bimetallic strips, shape memory alloys, or hydraulic expansion. However, these solutions generally suffer from slow response speed, low driving torque, high susceptibility to ambient temperature, and difficulty in achieving stable periodic motion.
[0006] In response to the aforementioned problems such as complex control system, low reliability, and small driving torque, this invention designs a solar street light with a solar panel featuring a spin function. Summary of the Invention
[0007] The purpose of this invention is to provide a solar street light with a solar panel featuring a spin function. Through the action of a spin clutch assembly, a spring gearbox, and a telescopic mechanism, the solar panel rotates horizontally following the sun, and then rotates back to the optimal position at sunrise the following day, corresponding to the optimal position at sunset, while also replenishing its potential energy. This achieves the function of the solar panel rotating horizontally following the sun during the day and resetting and storing energy the following day, realizing a periodic movement with the sun every day, and solving the problems mentioned above.
[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a solar street light with a self-spinning solar panel, comprising a self-spinning clutch assembly, a spring gearbox, and a telescopic mechanism. The self-spinning clutch assembly includes a self-spinning clutch control rod, a compound gear, and a spring seat. The compound gear is rotatably connected to the outer end of the spring seat. A guide separation part and a coupling are fixed to both ends of the self-spinning clutch control rod, respectively. The coupling at the end of the self-spinning clutch control rod is fixedly installed to the telescopic end of the telescopic mechanism. The telescopic mechanism controls the guide separation part of the self-spinning clutch control rod to compress and retract or disengage and reset the compound gear. The self-spinning clutch control rod controls the compound gear to be in the compressing and retracting or disengaging and resetting position. When the compound gear is in the reset position, it enables the spring power module to engage with the rotating shaft via the gear reducer and the compound gear. This means the spring gearbox controls the rotating shaft and its solar panel to rotate slowly, with a rotation cycle of approximately 12 hours. When the compound gear is in the retracted position, it is separated from the spring gearbox and the rotating shaft. The spring gearbox cannot control the slow rotation of the rotating shaft and its solar panel. At this time, the telescopic mechanism, through rack and pinion engagement, drives the spring core of the spring gearbox, winding the spring gearbox to achieve energy storage and replenish the potential energy released by the spring gearbox. The clockwork gearbox is fixedly installed inside the lamp post of the solar street light; the clockwork gearbox drives the rotating shaft of the solar panel through the meshing of compound gears; a rocker arm is fixedly installed on the circumferential side of the rotating shaft; a bearing is assembled between the circumferential side of the rotating shaft and the inner wall of the lamp post; A rack and a lever are fixedly mounted on the self-spinning clutch control lever. The telescopic mechanism drives the spring core of the spring gearbox through the meshing of the rack. The telescopic mechanism rotates and resets by the lever moving the rocker arm and the rotating shaft. When the telescopic mechanism extends, the lever moves the rocker arm to rotate the rotating shaft and the solar panel on it to the reset position. That is, the solar panel is rotated and reset from the optimal position at sunset to the optimal position at sunrise.
[0009] As a preferred technical solution of the present invention, the telescopic mechanism adopts an electric push rod; the telescopic mechanism (3) is connected to a controller by wire; the spin clutch control rod is fixed with a rack at the guide surface away from the guide separation part; the spin clutch control rod is perpendicular to the lever.
[0010] As a preferred embodiment of the present invention, the rocker arm has a sliding groove on the side near the lever; the inner wall of the sliding groove slides in conjunction with the circumferential side of the lever.
[0011] As a preferred embodiment of the present invention, the compound gear includes a clutch gear A, a clutch gear B, and a central shaft; the clutch gear A meshes with the output end of the clockwork gearbox; and the clutch gear B meshes with gear A.
[0012] As a preferred embodiment of the present invention, a gear A is fixedly mounted on the circumferential side of the rotating shaft; a connecting seat is fixed to the outer end of the spring seat, and the central shaft of the compound gear is rotatably fitted on the connecting seat via a bearing.
[0013] As a preferred embodiment of the present invention, the clockwork gearbox includes a clockwork power module and a gear reducer; the clockwork power module engages with the rotating shaft through the gear reducer and a compound gear.
[0014] As a preferred embodiment of the present invention, the mainspring power module is equipped with a mainspring core, and a gear B is fixed on the peripheral side of the mainspring core. The gear B meshes with a gearbox A, and the input end of the gearbox A meshes with a rack.
[0015] As a preferred embodiment of the present invention, a limiting groove plate is also fixedly installed inside the lamp post; a limiting channel is formed on the limiting groove plate, and the limiting channel slides with the rocker arm; the limiting channel on the limiting groove plate blocks the rocker arm and the solar panel on it from rotating to the optimal position corresponding to the sunset; thereby preventing the gearbox from releasing potential energy further and also preventing the rocker arm and the solar panel on it from continuing to rotate; therefore, the limiting channel limits the rotation angle range of the rocker arm and the solar panel on it to within 180°.
[0016] The present invention has the following beneficial effects: This invention utilizes a spin clutch assembly, a spring gearbox, and a telescopic mechanism to enable the solar panel to rotate horizontally in sync with the sun. This allows the solar panel to rotate horizontally with the sun during the day and reset and store energy the following day. It achieves the function of periodic movement with the sun every day and has the advantages of high mechanical stability, simple control system, low susceptibility to ambient temperature, and large driving torque.
[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1-7 As shown, this invention relates to a solar street light with a self-spinning solar panel, comprising a self-spinning clutch assembly 1, a spring gearbox 2, and a telescopic mechanism 3. The self-spinning clutch assembly 1 includes a self-spinning clutch control lever 101, a compound gear 102, and a spring seat 103. The compound gear 102 is rotatably connected to the outer end of the spring seat 103. A guide separation part 104 and a coupling 105 are respectively fixed at both ends of the self-spinning clutch control lever 101. The coupling 105 at the end of the self-spinning clutch control lever 101 is fixedly installed with the telescopic end of the telescopic mechanism 3. The telescopic mechanism 3 controls the guide separation part 104 of the self-spinning clutch control lever 101 to compress or disengage and reset the compound gear 102. The self-spinning clutch control lever 101 is used to control the compound gear 102 to be compressed and retracted or disengaged and reset. Position status: When the compound gear 102 is in the reset state, the compound gear 102 will cause the spring power module 202 to mesh with the rotating shaft 5 through the gear reducer 203 and the compound gear 102. That is, the spring gear box 2 controls the rotating shaft 5 and the solar panel on it to rotate slowly, and the rotation cycle is about 12 hours. When the compound gear 102 is in the retracted state, the compound gear 102, the spring gear box 2, and the rotating shaft 5 are all in a separated state. That is, the spring gear box 2 cannot control the rotating shaft 5 and the solar panel on it to rotate slowly. At this time, the telescopic mechanism 3 can mesh with the spring core 201 of the spring gear box 2 through the rack 106, so that the telescopic mechanism 3 winds the spring gear box 2 to achieve the energy storage effect, so as to replenish the potential energy released by the spring gear box 2. The clockwork gearbox 2 is fixedly installed inside the lamp post 4 of the solar street light; the clockwork gearbox 2 drives the rotating shaft 5 of the solar panel through the meshing of the compound gear 102; a rocker arm 501 is fixedly installed on the side of the rotating shaft 5; a bearing is assembled between the side of the rotating shaft 5 and the inner wall of the lamp post 4. A rack 106 and a lever 107 are fixedly mounted on the self-spinning clutch control lever 101. The telescopic mechanism 3 is driven by the mainspring core 201 of the mainspring gearbox 2 through the meshing of the rack 106. The telescopic mechanism 3 rotates and resets by moving the rocker arm 501 and the rotating shaft 5 through the lever 107. When the telescopic mechanism 3 extends, the lever 107 rotates the rotating shaft 5 and the solar panel on it to the reset position by moving the rocker arm 501. That is, the solar panel is rotated and reset from the optimal position at sunset to the optimal position at sunrise.
[0022] Among them, such as Figure 5 and Figure 7 As shown, the telescopic mechanism 3 uses an electric push rod; the telescopic mechanism 3 is connected to a controller by wires; the controller starts and stops the telescopic mechanism 3 at timed intervals through a timing module; the spin clutch control lever 101 has a rack 106 fixed on the guide surface away from the guide separation part 104; the spin clutch control lever 101 is perpendicular to the lever 107; the rocker arm 501 has a sliding groove 502 on the side near the lever 107; the inner wall of the sliding groove 502 slides with the circumferential side of the lever 107.
[0023] Among them, such as Figure 3-5 As shown, the compound gear 102 includes a clutch gear A1021, a clutch gear B1022, and a central shaft 1023; the clutch gear A1021 meshes with the output end of the clockwork gearbox 2; the clutch gear B1022 meshes with gear A503; gear A503 is fixedly mounted on the circumferential side of the rotating shaft 5; a connecting seat 108 is fixed to the outer end of the spring seat 103, and the central shaft 1023 of the compound gear 102 is rotatably fitted on the connecting seat 108 via a bearing.
[0024] Among them, such as Figure 6 As shown, the clockwork gearbox 2 includes a clockwork power module 202 and a gear reducer 203. The clockwork power module 202 meshes with the rotating shaft 5 through the gear reducer 203 and the compound gear 102. The reduction ratio of the gear reducer 203 is about 1:1440, which significantly reduces the rotation of the shaft 5 and the solar panel on it to a rate close to the angle change of sunlight, and achieves a speed reduction and torque increase effect. The clockwork power module 202 is equipped with a clockwork core 201, and a gear B204 is fixed on the circumferential side of the clockwork core 201. The gear B204 meshes with the gearbox A6, and the input end of the gearbox A6 meshes with the rack 106. A one-way bearing, i.e., an overrunning clutch, is installed on the input shaft of the gearbox A6, which causes the gearbox A6 to idle when the rack 106 is in the reset and retracted position, without driving the clockwork core 201 to rotate. That is, when the telescopic mechanism 3 extends, it drives the clockwork core 201 to wind, and when the telescopic mechanism 3 retracts, the gearbox A6 idles.
[0025] Among them, such as Figure 5As shown, a limiting groove plate 401 is also fixedly installed inside the lamp post 4; a limiting channel 402 is opened on the limiting groove plate 401, and the limiting channel 402 slides with the swing rod 501; the limiting channel 402 on the limiting groove plate 401 blocks the swing rod 501 and its solar panel when they rotate to the optimal position corresponding to the sunset; thus preventing the clockwork gearbox 2 from further releasing potential energy, and also preventing the swing rod 501 and its solar panel from continuing to rotate, so that the telescopic mechanism 3 can rotate and reset the solar panel from the optimal position corresponding to the sunset to the optimal position at sunrise the next day under the timed action; therefore, the limiting channel 402 limits the rotation angle range of the swing rod 501 and its solar panel to within 180°; its actual maximum rotation angle is set at about 120°.
