Description

Technical Field

[0001] This invention relates to the technical field of streetlights, and more specifically, to solar streetlights with LED lighting. Background Technology

[0002] To facilitate outdoor lighting, streetlights are generally installed on both sides of the road, which can provide nighttime road lighting for pedestrians or vehicles.

[0003] In the current technology, in order to save energy and protect the environment, many street lights are equipped with solar panels. The solar panels use solar energy to store electrical energy, and then use the electrical energy to power the light source of the street light to achieve lighting.

[0004] Since streetlights are installed outdoors, dust and other debris often accumulate on the solar panels over time. These deposits are difficult to remove, which greatly reduces the power generation efficiency of the solar panels and significantly shortens the lifespan of the streetlights.

The movable frame is provided with two spaced-apart swing bars, which are arranged transversely along the width direction of the solar panel. The two ends of the swing bars are elastically connected to the movable frame. Multiple elastic scrapers are movably connected to the swing bars, which reciprocate elastically along the length direction of the swing bars. The multiple elastic scrapers are arranged sequentially at intervals along the length direction of the swing bars. There is an elastic gap between adjacent elastic scrapers, and a width spring is provided in the elastic gap. The two ends of the width spring abut against the ends of the elastic scrapers. Along the width direction of the solar panel, the elastic scrapers on the two swing bars are staggered; as the moving frame moves along the length direction of the solar panel, the elastic scrapers scrape the surface of the solar panel, the two swing bars swing back and forth elastically in sync, and the multiple elastic scrapers on the swing bars rub back and forth laterally along the width direction of the solar panel.

[0007] Furthermore, the movable frame has end heads on both sides, and the lamp has channels on both sides.

[0010] Furthermore, the bottom of the swing bar is provided with a bottom-opening rail groove, the top of the elastic scraper has a top shaft, and the top shaft is movably placed in the rail groove; the elastic interval is formed in the rail groove and is located between the ends of adjacent top shafts, and the end of the width spring abuts against the end of the top shaft.

[0011] Furthermore, along the top axis from top to bottom, the end of the top axis is arranged at an angle to form an inclined surface, and the inclined surfaces of the top axes of the multiple elastic scrapers on the swing bar are arranged at an angle in the same direction, with the width spring abutting against the inclined surface.

[0012] Furthermore, the top shafts of the elastic scrapers on the two swing bars are arranged at opposite inclinations, and as the moving frame moves along the length of the solar panel, the elastic scrapers on the two swing bars rub laterally in opposite directions.

[0013] Furthermore, the width spring is wrapped with an elastic block in the middle, and the middle of the width spring is embedded inside the elastic block; the elastic block is placed in the rail groove and elastically presses against the inner side wall of the rail groove, so that the middle of the width spring is in an elastically fixed state.

[0014] Furthermore, along the width direction of the solar panel, the swing bars are arranged at an angle, and the two swing bars are arranged in opposite directions.

[0015] Furthermore, the bottom of the elastic scraper has two downward-extending scraper blades, the upper ends of the two scraper blades are abutted to the bottom of the elastic scraper, and the lower ends of the two scraper blades are arranged at opposite angles; the two scraper blades enclose a bottom groove with an open bottom, and the bottom of the bottom groove forms a bottom opening. The bottom groove has an elastic sheet extending downward from the top. Along the height direction of the elastic sheet, the elastic sheet is arranged in multiple curved sections. A scraping shaft is connected to the elastic sheet. The bottom of the scraping shaft is flush with the bottom opening. The bottom of the scraping shaft is provided with multiple scraping grooves. The scraping grooves extend along the axial direction of the scraping shaft and are spaced apart circumferentially along the scraping shaft. As the moving frame moves along the length of the solar panel, the scraper blades scrape the surface of the solar panel, and the scraping shaft simultaneously scrapes the surface of the solar panel.

[0021] Reference Figure 1-7 The image shows a preferred embodiment of the present invention.

[0022] The solar street light with LED illumination includes a light pole 100 and a long, strip-shaped luminaire 200. The luminaire 200 is mounted on the top of the light pole 100 and has a bottom surface 201 facing downwards. A light panel is mounted on the bottom surface 201, and multiple LED lights 202 are mounted on the light panel. The bottom of the light pole 100 is fixed to the road surface, and the multiple LEDs emit light downwards, achieving the effect of illuminating a limited area of ​​the road.

[0023] The top of the lamp 200 is covered with an upward-facing solar panel 204. The lamp 200 contains a battery electrically connected to the solar panel 204. A movable frame 300 is provided on the lamp 200, moving along the length of the solar panel 204. The movable frame 300 is located above the solar panel 204 and extends across its width. Since the solar panel 204 faces upward, during the day, sunlight directly shines on it, converting solar energy into electrical energy and storing it in the battery.

[0024] The movable frame 300 is provided with two spaced-apart swing bars 305, which span across the width of the solar panel 204. The two ends of the swing bars 305 are elastically connected to the movable frame 300. Multiple elastic scrapers 400 are movably connected to the swing bars 305, which reciprocate elastically along the length of the swing bars 305. The multiple elastic scrapers 400 are arranged sequentially at intervals along the length of the swing bars 305. There is an elastic gap 407 between adjacent elastic scrapers 400. A width spring 408 is provided in the elastic gap 407, and the two ends of the width spring 408 abut against the ends of the elastic scrapers 400. Along the width direction of the solar panel 204, the elastic scrapers 400 on the two swing bars 305 are staggered; as the moving frame 300 moves along the length direction of the solar panel 204, the elastic scrapers 400 scrape the surface of the solar panel 204, the two swing bars 305 swing back and forth elastically in sync, and the multiple elastic scrapers 400 on the swing bars 305 rub back and forth laterally along the width direction of the solar panel 204.

[0025] When it is necessary to remove the attachments on the solar panel 204, the movable frame 300 moves along the length of the solar panel 204, and the elastic scraper 400 scrapes the attachments on the solar panel 204 to remove them, ensuring the surface cleanliness of the solar panel 204, improving the power generation efficiency of the solar panel 204, and greatly extending the service life of the street light. Secondly, during the process of the elastic scraper 400 scraping the solar panel 204, the elastic scraper 400 is subjected to the friction force of the solar panel 204, and the two swing bars 305 swing back and forth elastically in sync, which can perform elastic impact scraping on the solar panel 204 to achieve more efficient scraping and cleaning; the multiple elastic scrapers 400 on the swing bars 305 rub back and forth laterally to achieve multi-directional scraping of the solar panel 204, as well as impact scraping of the solar panel 204, to achieve more efficient scraping and cleaning. In addition, during the process of scraping the solar panel 204, the elastic scraper 400 is blocked by the attached objects, especially bird droppings or other blocky objects. The elastic scraper 400 can achieve multi-directional elastic scraping and impact scraping to remove the attached objects.

[0026] A control board can be installed in the lamp 200 to realize timed control, so that the mobile frame 300 moves at a time to realize timed scraping of the solar panel 204.

[0027] In this embodiment, the movable frame 300 has end heads 301 on both sides, and the lamp 200 has channels on both sides. The channels extend along the length of the solar panel 204, and the end heads 301 are movably placed in the channels. The end head 301 has a threaded cylinder 302, and a rotatably arranged lead screw 303 is provided in the channel. The threaded cylinder 302 is sleeved on the lead screw 303 and threadedly connected to the lead screw 303. When the lead screw 303 rotates, it drives the threaded cylinder 302 to move along the lead screw 303, so that the moving frame 300 moves along the length direction of the solar panel 204.

[0028] The lead screw 303 is connected to the motor and is driven to rotate by the motor. When the lead screw 303 rotates, the threaded cylinder 302 moves along the lead screw 303, thereby enabling the moving frame 300 to move along the length of the solar panel 204.

[0029] In this embodiment, the end head 301 is provided with an end hole, and the swing bar 305 has an end section 3051 that is movably inserted through the end hole. The diameter of the end hole is larger than the diameter of the end section 3051. An elastic ring 3053 is sleeved on the outer periphery of the end section 3051 and is inserted through the end hole so that the end of the swing bar 305 is elastically connected to the end plate. During the movement of the moving frame 300 along the length direction of the solar panel 204, the end section 3051 reciprocates elastically in the elastic hole so that the swing bar 305 reciprocates elastically.

[0030] The end section 3051 and the end hole are elastically fitted by an elastic ring 3053 so that the end section 3051 can vibrate in the end hole, thus realizing the reciprocating swing of the swing bar 305.

[0031] In this embodiment, the interior of the elastic ring 3053 is hollow, forming a ring-shaped hollow cavity 3052, which surrounds the elastic ring 3053 circumferentially. By arranging the hollow cavity 3052, the elastic ring 3053 can achieve better elastic deformation capability, allowing the end segment 3051 to vibrate in multiple directions within the end hole, thereby achieving the effect of multi-directional oscillation of the swing bar 305.

[0032] In this embodiment, the bottom of the swing bar 305 is provided with a bottom-opening rail groove, the top of the elastic scraper 400 has a top shaft 401, and the top shaft 401 is movably placed in the rail groove; the elastic interval 407 is formed in the rail groove and is located between the ends of adjacent top shafts 401, and the end of the width spring 408 abuts against the end of the top shaft 401.

[0033] The top shaft 401 is movably placed in the track groove and can move along the length of the track groove. The elastic interval 407 is arranged with a width spring 408. When the elastic scraper 400 is scraping the solar panel 204, when the elastic scraper 400 is subjected to lateral pressure, the top shaft 401 moves back and forth along the track groove, and the width spring 408 reciprocates elastically.

[0034] In this embodiment, along the top shaft 401 from top to bottom, the end of the top shaft 401 is arranged at an angle to form an inclined surface 409. The inclined surfaces 409 of the top shaft 401 of the multiple elastic scrapers 400 on the swing bar 305 are arranged at an angle in the same direction, and the width spring 408 abuts against the inclined surface 409.

[0035] The end of the end shaft is designed as an inclined surface 409, and the width spring 408 abuts against the inclined surface 409. In this way, when the elastic scraper 400 is subjected to lateral pressure, it can move along the swing bar 305 with the top shaft 401, making it easier to realize the lateral rubbing of the elastic scraper 400, and making it easier for the width spring 408 to drive the elastic scraper 400 to move and reset elastically.

[0036] In this embodiment, the inclined surfaces 409 of the top shaft 401 of the elastic scrapers 400 on the two swing bars 305 are arranged at opposite inclinations. During the movement of the moving frame 300 along the length direction of the solar panel 204, the elastic scrapers 400 on the two swing bars 305 rub laterally in opposite directions.

[0037] The elastic scrapers 400 on the two swing bars 305 move laterally in opposite directions, which can realize the multi-directional reciprocating rubbing of the elastic scrapers 400 on the solar panel 204, making it easier for the elastic scrapers 400 to remove the attachments on the solar panel 204.

[0038] In this embodiment, the middle part of the width spring 408 is wrapped with an elastic block 410, and the middle part of the width spring 408 is embedded inside the elastic block 410; the elastic block 410 is placed in the rail groove and elastically presses against the inner side wall of the rail groove so that the middle part of the width spring 408 is in an elastically fixed state.

[0039] In this way, the middle part of the spring is in an elastically fixed state, which facilitates the elastic deformation of the width spring 408 and avoids phenomena such as bending of the axis of the width spring 408, so that the elastic deformation of the width spring 408 is smoother, thereby making the reciprocating movement of the elastic scraper 400 smoother.

[0040] In this embodiment, the swing bars 305 are arranged at an angle along the width of the solar panel 204, and the two swing bars 305 are arranged in opposite directions. In this way, the swing bars 305 can swing more effectively during movement, so that the multiple elastic scrapers 400 can simultaneously perform reciprocating vibration scraping, thereby cleaning the deposits on the solar panel 204 more efficiently.

[0041] In this embodiment, the bottom of the elastic scraper 400 has two downwardly extending scraper blades 402. The upper ends of the two scraper blades 402 are connected to the bottom of the elastic scraper 400, and the lower ends of the two scraper blades 402 are arranged at an angle away from each other. The two scraper blades 402 enclose a bottom groove 403 with an open bottom, and the bottom of the bottom groove 403 forms a bottom opening. An elastic sheet 404 extends downward from the top of the bottom groove 403. The elastic sheet 404 is arranged in multiple curved sections along its height direction. A scraping shaft 405 is connected to the elastic sheet 404. The bottom of the scraping shaft 405 is flush with the bottom opening. The bottom of the scraping shaft 405 is provided with multiple scraping grooves 406. The scraping grooves 406 extend along the axial direction of the scraping shaft 405. The multiple scraping grooves 406 are arranged at intervals along the circumference of the scraping shaft 405. As the moving frame 300 moves along the length of the solar panel 204, the scraper 402 scrapes the surface of the solar panel 204, and the scraping shaft 405 simultaneously scrapes the surface of the solar panel 204.

[0042] The elastic scraper 402 uses an inclined scraper 402 to scrape the solar panel 204, which can simulate a scraping motion to make the scraping more thorough. Secondly, during the scraping process of the solar panel 204, the scraping shaft 405 can perform elastic scraping on the solar panel 204, further improving the scraping efficiency. In addition, the scraping groove 406 on the scraping shaft 405 can achieve better scraping of the solar panel 204.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
