[0001] The present invention relates to the technical field of the solar energy industry, and particularly to a high-efficiency energy-gathering conversion device for solar street lamps. Background Art

[0002] In rainy or overcast weather or in areas with weak sunlight at high latitudes, the power generation of traditional systems drops sharply. Therefore, solar energy needs to be used as the power source for street lamps. As the core device for green lighting, solar street lamps are widely used in urban and rural roads, parks, parking lots and other scenarios. The core challenge lies in how to improve the conversion efficiency among light energy, electrical energy and light energy.

[0003] Existing solar street lamps can collect the light energy of the sun during the day, convert the light energy of the sun into electrical energy, and then achieve the lighting of the street lamps. However, when the sun's rays are relatively dim, the light energy collection efficiency of the solar cells will decrease, and the light is weak, so that the light energy emitted by the sun cannot be concentrated on the solar panel, resulting in poor light concentration effect of existing solar street lamps in an environment with weak light.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When in use, by utilizing the principle of annular lens to refract sunlight, the sunlight can be concentrated on the surface of the solar panel in a weak light environment, thereby improving the energy collection efficiency in a weak light environment. The solar radiation sensor can monitor the radiation intensity in real time. When the radiation intensity is high, the annular lens will be blocked to prevent the sunlight from being too strong. When the radiation intensity is low, there is no need to block the annular lens. By starting the servo motor, the elastic shade cloth and the elastic rope are unfolded to enable the annular lens to collect energy. By simultaneously retracting multiple fixed rods inward until the elastic shade cloth covers the annular lens, the annular lens's collection of sunlight is interrupted.

[0018] 2. When in use, by installing the lighting lamp on a fixed curved rod and bending the fixed curved rod toward the road surface, the road surface can be illuminated in a larger range. The total solar radiation is measured by the solar radiation sensor, and the energy-gathering and shielding effect is adjusted according to the intensity of the solar radiation. When a vehicle passes by on the ground or the light pole is blown by the wind, it will vibrate. At this time, the piezoelectric ceramic will generate an electric charge when the pole body of the light pole vibrates, which will be stored after rectification by the circuit, so that the electrical energy generated by the vibration can be stored on the basis of storing solar energy, which has the effect of multi-directional energy gathering.

[0019] 3. When in use, the self-cleaning coating is applied to the front surface glass of the solar panel on the illuminated side so that it is directly exposed to the environment. The material used in the self-cleaning coating is nano titanium dioxide. It reduces dust adhesion through photocatalysis and super hydrophilicity, thereby improving power generation efficiency. In addition, the self-cleaning coating has super hydrophilicity, which will cause rainwater to form a uniform water film. Rainwater washes away dust and can avoid water stains after drying, reducing manual cleaning. Unplug the plug and start the forward and reverse motors to rotate the output shaft, thereby driving the driving gear to rotate. Since the rotation center of the fixed frame and the driving gear is the same, the driving gear will engage when it rotates to drive the adjusting gear plate to rotate, thereby adjusting the direction of the solar panel. It has the benefit of enabling the solar panel to automatically adjust its orientation according to the direction of the sun, achieving the best energy collection effect.

Detailed implementation mode

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Refer to Figures 1-9 As shown, the present invention provides a technical solution: a high-efficiency energy-gathering conversion device for a solar street lamp, including a street lamp assembly 2, a solar component 3, and an energy-gathering component 4. The solar component 3 absorbs and converts solar energy into electrical energy to enable the street lamp assembly 2 to achieve road lighting. Among them, the energy-gathering component 4 can aggregate sunlight in an environment with weak light. The solar component 3 includes a solar panel 312, and a self-cleaning coating 309 is provided on the surface of the solar panel 312, and the material used for the self-cleaning coating 309 is nano-titanium dioxide; the energy-gathering component 4 includes a driven rotating ring 405 and a ring lens 412, and the ring lens 412 is used to aggregate the sunlight irradiated on the surface of the solar panel 312. A plurality of engaging levers 413 are fixedly connected to the top of the driven rotating ring 405. A plurality of rotating sleeves 407 are movably sleeved outside the driven rotating ring 405. A limiting groove 408 is opened on the outer surface of each rotating sleeve 407. A fixing rod 417 is fixedly connected to the inner wall of each limiting groove 408. A elastic cord 416 is fixedly connected between one ends of the plurality of fixing rods 417. An elastic light-shielding cloth 411 is fixedly connected between the outer surfaces of the plurality of fixing rods 417. The elastic light-shielding cloth 411 is used to block the sunlight irradiated on the surface of the ring lens 412. The energy-gathering component 4 further includes two support rods 414. The two support rods 414 are respectively fixedly installed on both sides of the mounting frame 303. Mounting rods 415 are fixedly connected to the outer surfaces of the two support rods 414. One ends of the two mounting rods 415 are fixedly installed at the bottom of the ring lens 412. A fixing ring 401 is fixedly connected between one ends of the two support rods 414. A plurality of bearing rods 404 are fixedly connected to the bottom of the fixing ring 401. One ends of the plurality of bearing rods 404 are movably connected to the inner part of the bottom groove of the driven rotating ring 405. A plurality of limiting blocks 406 are fixedly connected to the inner wall of the fixing ring 401. The outer surfaces of the plurality of limiting blocks 406 are respectively movably connected to the inner walls of the plurality of limiting grooves 408. A servo motor 402 is provided at the bottom of one side of the fixing ring 401. The output shaft of the servo motor 402 is fixedly connected to an adjusting gear 403. A plurality of tooth grooves 410 are opened on the outer surface of the driven rotating ring 405, and the inner walls of the plurality of tooth grooves 410 are engaged with the teeth of the adjusting gear 403. A plurality of engaging levers 413 are fixedly connected to the top of the driven rotating ring 405 along the circumferential direction. A plurality of inclined engaging grooves 409 are opened on the inner wall of each rotating sleeve 407, and the inclined engaging grooves 409 are engaged with the engaging levers 413.

[0033] In this embodiment, when in use, by utilizing the principle of refracting sunlight with the annular lens 412, the sunlight can be concentrated and irradiated on the surface of the solar panel 312 in a low-light environment, thereby improving the energy concentration efficiency in a low-light environment. The solar radiation sensor 5 can monitor the radiation intensity in real time. When the radiation intensity is high, the annular lens 412 is blocked to avoid too strong sunlight. When the radiation intensity is low, there is no need to block the annular lens 412. The blocking method is as follows: By starting the servo motor 402, its output shaft rotates, thereby driving the adjusting gear 403 to rotate. Since the teeth of the adjusting gear 403 are engaged with the tooth grooves 410, when the adjusting gear 403 rotates, the driven rotating ring 405 will rotate. Among them, the bearing rod 404 plays a role in supporting and limiting the driven rotating ring 405. When the driven rotating ring 405 rotates, the engaging lever 413 will continuously and alternately engage the inclined engaging grooves 409 inside each rotating sleeve 407. Since the inclined engaging grooves 409 are inclined, the rotating sleeve 407 will rotate in place. At this time, the limiting block 406 slides inside the limiting groove 408, which can limit the rotating sleeve 407 to rotate in place. The rotation of the rotating sleeve 407 will drive the fixing rods 417 to expand outward or retract inward simultaneously. When the plurality of fixing rods 417 expand outward simultaneously, the elastic light-shielding cloth 411 and the elastic ropes 416 will be stretched and expanded outward, so as to concentrate the energy of the annular lens 412. By retracting the plurality of fixing rods 417 inward simultaneously until the elastic light-shielding cloth 411 covers the annular lens 412, the energy concentration of the annular lens 412 on sunlight is interrupted.

[0034] Embodiment Two: Figures 1-9 As shown in the figure, the street lamp assembly 2 includes a street lamp pole 201. The top of the street lamp pole 201 is fixedly connected with a fixed bent rod 202. One end of the fixed bent rod 202 is provided with a lighting lamp 203. The outer surface of the street lamp pole 201 near its top is fixedly connected with a fixing plate 204. The top of the fixing plate 204 is provided with a solar radiation sensor 5. The bottom end of the street lamp pole 201 is welded with a mounting plate 205. Between the bottom end of the street lamp pole 201 and the top of the mounting plate 205, an energy conversion assembly 1 is welded. The energy conversion assembly 1 includes a support bottom column 101. A plurality of piezoelectric ceramics 102 are arranged on the inner bottom surface of the support bottom column 101. The plurality of piezoelectric ceramics 102 are arranged in series. The top of the support bottom column 101 is snap-fitted with a protective cover 103. The protective cover 103 is slidably sleeved outside the street lamp pole 201. The bottom of the protective cover 103 is fixedly connected with a plurality of reinforcing ribs 104, and the plurality of reinforcing ribs 104 are used to improve the firmness inside the support bottom column 101.

[0035] In this embodiment, during use, first use ground nails to fix the mounting plate 205 on the road surface. The mounting plate 205 is used to increase the overall stability of the street lamp. By installing the lighting lamp 203 on the fixed bent rod 202, the fixed bent rod 202 bends towards the road surface, which can illuminate the road surface in a larger range. Install the fixed plate 204 at the top of the street lamp pole 201, and then install the solar radiation sensor 5 on the fixed plate 204. The solar radiation sensor 5 measures the total solar radiation, and adjusts the energy-gathering and shielding effect according to the solar radiation intensity. When a vehicle passes on the ground or the street lamp pole 201 is blown by the wind, vibrations will occur. At this time, the piezoelectric ceramic 102 generates charges when the rod body of the street lamp pole 201 vibrates, and the charges are stored after being rectified by the circuit. Therefore, the electrical energy generated by the vibration can be stored on the basis of storing solar energy, and it has the effect of multi-directional energy gathering.

[0036] Embodiment Three: Figures 1-9 As shown in the figure, the solar energy component 3 includes a solar panel 312. A self-cleaning coating 309 is provided on the surface of the solar panel 312, and the material used for the self-cleaning coating 309 is nano-titanium dioxide. The solar energy component 3 also includes a fixture 301. The fixture 301 is clamped outside the fixed bent rod 202. A connecting frame 302 is fixedly connected to the outer surface of the fixture 301. An installation frame 303 is fixedly connected to the outer surface of the connecting frame 302. A positive and negative motor 308 is arranged on the inner wall of the installation frame 303. The output shaft of the positive and negative motor 308 is fixedly connected to a driving gear 304. A fixed frame 307 is rotatably connected between the two sides of the installation frame 303 through a rotating shaft. A regulating toothed plate 306 is fixedly connected to the inner wall of one side of the fixed frame 307. An arc-shaped hole 305 is opened on one side of the installation frame 303. The regulating toothed plate 306 slides on the inner wall of the arc-shaped hole 305. The outer surface of the regulating toothed plate 306 is meshed with the outer surface of the driving gear 304. A plurality of positioning insertion holes 310 are opened on the other side of the installation frame 303. A plug is slidably embedded on the other side of the fixed frame 307, and the plug is used to insert into the positioning insertion holes 310 to position the fixed frame 307. Two reinforcing blocks 311 are symmetrically installed on the top of the fixed frame 307. The solar panel 312 is arranged between one ends of the two reinforcing blocks 311.

[0037] In this embodiment, during use, the solar panel 312 absorbs the energy of the sun and converts it into electrical energy to power the street lamp, achieving night lighting for the road. By applying the self-cleaning coating 309 on the front surface glass of the light-receiving surface of the solar panel 312, making it directly exposed to the environment, the material used for the self-cleaning coating 309 is nano-titanium dioxide. Dust adhesion is reduced through photocatalysis and superhydrophilicity, thereby improving the power generation efficiency. Moreover, the self-cleaning coating 309 has superhydrophilicity, which causes rainwater to form a uniform water film. The rainwater washes away the dust, and water stains can be avoided after drying, reducing manual cleaning. By tightly clamping the fixture 301 outside the fixed bent rod 202, the installation of the solar panel 312 is completed. By using the insertion block to penetrate both the fixing bracket 307 and a positioning jack 310 at the corresponding position simultaneously, the solar panel 312 can be limited to a fixed position. However, after removing the insertion block, by starting the forward and reverse motor 308 and rotating its output shaft, the driving gear 304 is driven to rotate. Since the rotation centers of the fixing bracket 307 and the driving gear 304 are the same, when the driving gear 304 rotates, it will engage and drive the adjusting toothed plate 306 to rotate, thereby enabling the direction of the solar panel 312 to be adjusted. This has the advantage that the solar panel 312 can automatically adjust its orientation according to the direction of the sun, achieving the best energy-gathering effect.

[0038] Usage method and working principle of this device: When in use, first use ground nails to fix the mounting plate 205 on the road surface. The mounting plate 205 is used to increase the overall stability of the street lamp. By installing the lighting lamp 203 on the fixed bent rod 202, and the fixed bent rod 202 bends towards the road surface, it can illuminate the road surface in a larger range. Install the fixing plate 204 at the top of the street lamp pole 201, and then install the solar radiation sensor 5 on the fixing plate 204. The solar radiation sensor 5 measures the total solar radiation, and adjusts the energy-gathering shielding effect according to the solar radiation intensity. When there are vehicles passing by on the ground or the street lamp pole 201 is blown by the wind, vibrations will occur. At this time, the piezoelectric ceramic 102 will generate charges when the pole body of the street lamp pole 201 vibrates, and after being rectified by the circuit, it is stored, so that the electric energy generated by the vibration can be stored on the basis of storing solar energy. When in use, the solar panel 312 will absorb the energy of the sun and convert it into electric energy to supply power to the street lamp to achieve night lighting of the road. By coating the self-cleaning coating 309 on the front surface glass of the light-receiving surface of the solar panel 312, making it directly exposed to the environment, the material used for the self-cleaning coating 309 is nano-titanium dioxide, which reduces dust adhesion through photocatalysis and superhydrophilicity, thereby improving the power generation efficiency. Moreover, the self-cleaning coating 309 has superhydrophilicity, which will make rainwater form a uniform water film, and the rainwater washes away the dust, avoiding water stains remaining after drying. By tightly clamping the fixture 301 outside the fixed bent rod 202, the installation of the solar panel 312 is completed. By using the plug to penetrate through the fixing frame 307 and a positioning jack 310 at the corresponding position at the same time, the solar panel 312 can be limited in a fixed position. However, after pulling out the plug, by starting the forward and reverse motor 308, its output shaft rotates, thereby driving the driving gear 304 to rotate. Since the rotation centers of the fixing frame 307 and the driving gear 304 are the same, when the driving gear 304 rotates, it will engage and drive the adjusting tooth plate 306 to rotate, so that the direction of the solar panel 312 can be adjusted. When in use, by using the principle of refracting sunlight by the annular lens 412, the sun's rays can be concentrated and irradiated on the surface of the solar panel 312 in a low-light environment. The solar radiation sensor 5 can monitor the radiation intensity in real time. When the radiation intensity is large, the annular lens 412 is blocked to avoid too strong sunlight. When the radiation intensity is small, there is no need to block the annular lens 412. The blocking method is: by starting the servo motor 402, its output shaft rotates, thereby driving the adjusting gear 403 to rotate. Since the teeth of the adjusting gear 403 are engaged with the tooth grooves 410, when the adjusting gear 403 rotates, the driven rotating ring 405 will rotate. Among them, the bearing rod 404 plays a role in supporting and limiting the driven rotating ring 405. When the driven rotating ring 405 rotates, the engaging lever 413 will continuously and alternately engage the inclined engaging grooves 409 inside each rotating sleeve 407. Since the inclined engaging grooves 409 are inclined, the rotating sleeve 407 will rotate in place. At this time,The limiting block 406 slides inside the limiting groove 408, which can limit the rotation sleeve 407 to rotate in place. Through the rotation of the rotation sleeve 407, the fixed rod 417 will be driven to expand outward or retract inward simultaneously. When multiple fixed rods 417 expand outward simultaneously, the elastic light-shielding cloth 411 and the elastic cord 416 will be stretched and expanded outward, so as to concentrate the energy of the annular lens 412. By retracting multiple fixed rods 417 inward simultaneously until the elastic light-shielding cloth 411 covers the annular lens 412, the energy concentration of the annular lens 412 on sunlight is interrupted.

[0039] The wiring diagrams of the lighting lamp 203, the forward and reverse motor 308, the servo motor 402, and the solar radiation sensor 5 in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the lighting lamp 203, the forward and reverse motor 308, the servo motor 402, and the solar radiation sensor 5 will not be explained in detail.
