Description

Technical Field

[0001] The present invention belongs to the field of solar lighting lamps, and particularly relates to a charging protection device for a solar lighting lamp. Background Art

[0002] For a small household solar lighting lamp, the lighting lamp and the solar panel are separately designed. On the one hand, it is convenient for installation, and on the other hand, it can match solar panels with different areas. After installing the lighting lamp at a fixed position, the solar panel is then installed so that the solar panel can receive sunlight, convert solar energy into electrical energy, and store it for the lighting lamp to use. However, for a solar panel with a fixed angle, the power generation efficiency decreases after the position of the sun changes. In addition, for a solar panel set upward, after pollutants such as dust, dirt, and bird droppings fall on the surface, the incidence of sunlight is blocked, resulting in a decrease in power generation efficiency. For example, a severely polluted solar panel may lose 20%-30% of its power generation capacity. On a snowy day, the snow on the surface of the solar panel will also affect the incidence of sunlight. In a hail weather, the hail directly hitting the surface of the solar panel may also damage the solar panel.

[0003] Based on this, the present application provides a charging protection device for a solar lighting lamp. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. 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 making creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figure 1-7 , the present invention provides a technical solution for a charging protection device of a solar lighting lamp:

[0028] A charging protection device for a solar lighting lamp is used to protect a solar panel 1. The solar panel 1 is arranged on a wall or a column. An installation arm 2 is arranged on the wall or the column through expansion bolts. A mounting plate 3 is vertically and fixedly arranged at one end of the installation arm 2. The mounting plate 3 is parallel to the surface of the wall or the column. A fixing plate 4 is arranged on the back surface of the solar panel 1. The fixing plate 4 is clamped and fixed on the solar panel 1. A rotating seat 5 is arranged on the fixing plate 4. The rotating seat 5 is composed of two symmetric end plates 6 on the left and right.

[0029] A driving motor 7 is arranged on the side of the mounting plate 3 facing the wall or the column. A light chasing seat 8 is rotatably arranged on the other side of the mounting plate 3. The output shaft of the driving motor 7 and the light chasing seat 8 are coaxially fixed by key connection. A return torsion spring (not shown in the figure) is arranged between the light chasing seat 8 and the mounting plate 3. The return torsion spring is sleeved on the rotating shaft of the light chasing seat 8. The rotating seat 5 is rotatably arranged on the light chasing seat 8. Two ear plates 9 are symmetrically arranged on the left and right on the light chasing seat 8. The driving shafts 10 are rotatably arranged at the ends of the two ear plates 9 far away from the light chasing seat 8. The rotating seat 5 and the driving shafts 10 are fixedly connected by key connection. The two ear plates 9 are located between the two end plates 6. When the driving motor 7 rotates, it drives the light chasing seat 8, the rotating seat 5 and the solar panel 1 to rotate around the mounting plate 3. After the driving motor 7 stops rotating, it resets under the action of the torsion spring.

[0030] A linkage mechanism is provided between the light-tracking base 8 and the mounting plate 3. When the driving motor 7 drives the light-tracking base 8 to rotate around the mounting plate 3, under the action of the linkage mechanism, the rotating seat 5 drives the solar panel 1 to rotate around the light-tracking base 8 to a set angle and then stops rotating and maintains the state. The linkage mechanism includes a fixed gear 11, a driven gear 12, a bevel gear set 13, a lead screw 14 and a slider 15. The fixed gear 11 is fixedly arranged on the mounting plate 3. A connecting frame 16 is arranged on the mounting plate 3, and the fixed gear 11 is fixed on the connecting frame 16. The fixed gear 11 is coaxial with the output shaft of the driving motor 7. The driven gear 12 is rotatably arranged on the light-tracking base 8, and the driven gear 12 is meshed with the fixed gear 11 for transmission. The lead screw 14 is rotatably arranged between the two end plates 6. The lead screw 14 is parallel to the driving shaft 10. The lead screw 14 is perpendicular and intersects with the rotating shaft of the driven gear 12. The lead screw 14 and the rotating shaft of the driven gear 12 are driven by the bevel gear set 13. A guide shaft 17 is also arranged between the two end plates 6. The guide shaft 17 is parallel to the lead screw 14. The slider 15 is slidably arranged on the guide shaft 17. The slider 15 is meshed with the lead screw 14. The slider 15 is sleeved on the driving shaft 10. A driving track groove is arranged on the driving shaft 10. The driving track groove includes a spiral groove 18 and a straight groove 19. The spiral groove 18 and the straight groove 19 are smoothly transitionally connected. A guide post 20 is arranged on the slider 15, and the guide post 20 cooperates with the driving track groove.

[0031] The device is also provided with a cleaning component for scraping the stains on the surface of the solar panel 1. The cleaning component includes a scraper slidably arranged on the surface of the solar panel 1 and a driving member for driving the scraper to slide. The driving member is composed of a wire reel 24 and a pull rope 25. A fixed shaft 23 is arranged on the mounting arm 2. A wire reel 24 is rotatably arranged at each end of the fixed shaft 23. A return torsion spring (not shown in the figure) is arranged between the wire reel 24 and the fixed shaft 23. One end of the pull rope 25 is fixed to one end of the scraper, and the other end is wound around the corresponding wire reel 24.

[0032] In order to protect the rotating seat 5, the driving motor 7, the light-tracking base 8 and the linkage mechanism, a protective cover 21 is arranged between the fixing plate 4 and the mounting seat. The protective cover 21 is sleeved on the above components to protect them from rain, dust, etc.

[0033] The solar panel 1 is used in combination with the lighting lamp 22. A storage battery, a controller and a power sensor are arranged in the housing of the lighting lamp 22. The storage battery is electrically connected to the solar charging panel. When the solar panel 1 works, the controller controls the angle state of the solar panel 1 according to the charging power of the storage battery by the solar panel 1.

[0034] Working principle: Install the solar panel 1 and the lighting lamp 22 in the initial state as Figure 1 shown on the wall or the column. The initial state includes when lighting, when the storage battery is fully charged, and when the charging power of the solar panel 1 is not within the set range.

[0035] When switching from the initial state to the charging state, the drive motor 7 is started. The output shaft of the drive motor 7 drives the light chasing base 8 to rotate. The light chasing base 8 drives the driven gear 12 to rotate around the fixed gear 11. Since the fixed gear 11 is stationary, the driven gear 12 rotates itself, and the rotating shaft of the driven gear 12 rotates. Under the transmission of the bevel gear set 13, the lead screw 14 rotates. The rotation of the lead screw 14 drives the slider 15 to slide. When the slider 15 slides, the guide post 20 moves along the driving track groove, and the relative drive shaft 10 rotates. The drive shaft 10 drives the rotating base 5 and the solar panel 1 to rotate. When the guide post 20 slides in the spiral groove 18, the solar panel 1 rotates around the light chasing plate, so that the solar panel 1 rotates from being inclined downward to being inclined upward for solar power generation. When the guide post 20 slides into the straight groove 19, the solar panel 1 maintains the state of being inclined upward. In the process of the light chasing base 8 rotating at the initial stage, within a relatively small angle, the guide post 20 has moved into the straight groove 19. That is to say, at the initial stage after the drive motor 7 is started, the solar panel 1 is already inclined upward. Subsequently, under the action of the drive motor 7, the light chasing base 8 rotates to drive the solar panel 1 to follow the sun to rotate to obtain a stable charging power.

[0036] In the above process, when the solar panel 1 rotates from being inclined downward to being inclined upward, the pull rope 25 is first pulled to store force in the return torsion spring. When the solar panel 1 is completely flipped to the state of being inclined upward, the return torsion spring winds the stretch on the winding wheel 24 again. During this process, the scraper slides from one side of the solar panel 1 to the other side to scrape the stains on the surface of the solar panel 1, thereby improving the charging efficiency of the solar panel 1. When the battery is fully charged, the charging power of the solar panel 1 is not within the set range, or when the sun sets, the drive motor 7 is turned off. Under the action of the reset torsion spring, the light chasing base 8 returns to the initial state, and the state of the solar panel 1 being inclined upward is flipped to the state of being inclined downward. The scraper slides from one end of the solar panel 1 to the other end again.

[0037] The start and stop of the drive motor 7 are executed according to the instructions of the controller. The controller directly obtains when to start and stop the drive motor 7 based on the power sensor.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art of this technology, within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, make equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
