Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic power generation equipment based on renewable clean energy. Background Art

[0002] Clean energy, also known as green energy, refers to energy that does not emit pollutants and can be directly used for production and life, including renewable energy and energy that is low-pollution or non-polluting to the ecological environment in the production and consumption of energy. Renewable energy includes hydropower, bioenergy, solar energy, wind energy, geothermal energy and ocean energy, etc. When collecting solar energy, photovoltaic power generation equipment is generally used to collect and convert the sun; existing photovoltaic power generation equipment uses solar trackers to drive solar panels to rotate, ensuring that the solar panels can follow the trajectory of the sun to adjust the angle, thereby improving the power generation efficiency of photovoltaic panels. Since solar panels are placed outdoors and the installation location is limited, and solar panels In relatively severe conditions, which are easily affected by hail or surrounding debris, the screw rod will generally move downward to drive the mounting bar to slide downward inside the collection box. At this time, the solar panels installed outside the mounting bar rotate relatively and move synchronously downward into the collection box to protect the solar panels. Since the mounting bar moves downward and drives the unfolded solar panels to slide downward synchronously, the solar panels and the collection box come into contact and push the solar panels to move along the outside of the mounting bar. However, the solar panels and the collection box slide against each other, which increases the friction between the solar panels and the collection box when they move downward, thereby causing scratches on the solar panels, affecting the structural stability of the solar panels, and reducing the photoelectric conversion efficiency of the solar panels. Summary of the invention

[0003] The purpose of the present invention is to provide a photovoltaic power generation equipment based on renewable clean energy. Through the setting of a translational rising component, the solar panel can be moved downward in the sun-collecting window and horizontally moved into a collection box for collection, so that there is a height difference between the solar panel and the collection box during collection, thereby avoiding the solar panel from sliding against each other and causing scratches on the solar panel, thereby improving the photoelectric conversion efficiency of the solar panel and solving the above-mentioned deficiencies in the technology.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-Figure 5 A photovoltaic power generation device based on renewable clean energy is shown, comprising: a sun tracking seat 1 and a solar panel 12, a rotatable collecting box 11 is installed on the top of the sun tracking seat 1, and a sun collecting window 13 is opened on the top of the collecting box 11 for placing the solar panel 12;

[0035] Multiple groups of translation and rising components 2 are used to drive the solar panel 12 to slide into the collection box 11 in the sun collection window 13. Each translation and rising component 2 includes an ear plate 21 fixed at the bottom corner of the solar panel 12, a bottom plate 29 slidably installed in the collection box 11, and a first mounting shaft column 22 installed on one side of the ear plate 21. A second mounting shaft column 23 is installed on one side of the bottom plate 29, and the second mounting shaft column 23 and the first mounting shaft column 22 are rotatably connected with a mounting ring 24. A diagonal support rod 25 is installed between the two mounting rings 24. The collection box 11 Two guide assemblies are provided inside for driving two groups of translation and rising assemblies 2. A translation assembly 3 is provided inside the collection box 11 for driving the bottom plate 29 to slide. A high-efficiency assembly 5 for cleaning the top of the solar panel 12 is provided on the top of the collection box 11. A closing assembly 4 is provided on the translation assembly 3, and the closing assembly 4 is used to open or close the sun-collecting window 13. Each guide assembly includes a guide plate 26 fixed in the collection box 11 and a pulley 27 installed at one end of one of the first mounting shaft columns 22. An L guide groove 28 for the pulley 27 to slide is provided on one side of the guide plate 26.

[0036] The translation assembly 3 includes a translation stabilizing block 35 fixed on both sides of the base plate 29, two translation slots 36 opened in the sun tracking seat 1 for the two translation stabilizing blocks 35 to slide, and a rotating rod 31 rotatably installed in the collection box 11, the outer part of the rotating rod 31 is fixedly sleeved with a first gear 32, a first rack 34 is fixed in the middle of the bottom end of the base plate 29, and the first rack 34 is engaged with the first gear 32, a servo motor 33 is fixed in the collection box 11, and the servo motor 33 is used to drive the rotating rod 31 to rotate.

[0037] When the photovoltaic panel is collecting and protecting, the servo motor 33 drives the rotating rod 31 to rotate, and then the rotating rod 31 rotates to drive the first gear 32 to rotate. At this time, the first gear 32 and the first rack 34 are engaged with each other to drive the bottom plate 29 to move deep into the collection box 11, and the movement of the bottom plate 29 drives the translation stabilizing block 35 to slide synchronously along the translation groove 36, and the movement of the bottom plate 29 drives the second installation shaft column 23 to move, and the movement of the second installation shaft column 23 drives the diagonal support rod 25 to move and pull the first installation shaft column 22 downward in the L guide groove 28, so that the pulley 27 slowly moves to the bottom of the L guide groove 28, so that the ear plate 21 slides downward in the sun-collecting window 13, and the sun is pre-installed. The solar panel 12 moves downward in the sun-collecting window 13 to achieve the first adjustment of the solar panel 12. At this time, the bottom of the solar panel 12 is parallel to the top of the bottom plate 29, and the top of the solar panel 12 is kept at a distance from the top of the collection box 11. However, the first gear 32 continues to drive the bottom plate 29 to move into the collection box 11 under the continuous transmission with the first rack 34. As the pulley 27 moves horizontally along the L guide groove 28, the ear plate 21 moves horizontally along the sun-collecting window 13 toward the deep inside of the collection box 11. Then, the solar panel 12 slides out of the sun-collecting window 13 and moves toward the deep inside of the collection box 11, and the solar panel 12 is collected in the collection box 11, thereby effectively protecting the solar panel 12.

[0038] refer to Figure 1-Figure 7 As shown, the closing component 4 includes a second gear 45 rotatably installed on one side of the rotating rod 31, a closing groove 41 opened at the top of the collecting box 11 and communicating with the inside of the sun-collecting window 13, and a closing plate 42 slidably installed in the closing groove 41, and the closing plate 42 passes through the closing groove 41 to cover and open the sun-collecting window 13, and a second rack 46 matched with the second gear 45 is installed on one side of the collecting box 11, and the second rack 46 is provided with a connecting component for driving the closing plate 42 to move; the connecting component includes a connecting ear column 47 fixed on one side of the closing plate 42 and a guide rod 44 fixed at one end of the second rack 46, and a guide groove 43 is opened on one side of the collecting box 11 and communicates with the inside of the closing plate 42 for the guide rod 44 to slide, and one end of the connecting ear column 47 extends into the closing groove 41 and is fixed to the top of the guide rod 44.

[0039] Through the above technical solution:

[0040] When the solar panel 12 is being collected and protected, the rotating rod 31 first rotates in the collecting box 11 to drive the second gear 45 to rotate along one side of the collecting box 11. The second gear 45 rotates and engages with the second rack 46, and then the second rack 46 slides along one side of the collecting box 11. At this time, the second rack 46 moves to drive the guide rod 44 to slide along the guide groove 43. However, the movement of the guide groove 43 drives the connecting ear column 47 to slide along the closing groove 41. As the connecting ear column 47 pushes the closing plate 42 to slide along the closing groove 41, one end of the closing plate 42 passes through the closing plate 42 and moves into the sun-collecting window 13. The closing plate 42 moves into the sun-collecting window 13 and intersects with the solar panel 12, and then the closing plate 42 closes the sun-collecting window 13.

[0041] refer to Figure 5-Figure 8 As shown, the high-efficiency component 5 includes a movable groove 55 opened on the inner top wall of the collecting box 11, a cleaning brush 53 that can be fitted on the solar panel 12, and two connecting frames 51 symmetrically installed in the movable groove 55, and a rotatable cleaning rod 52 is installed between the two connecting frames 51, the cleaning rod 52 and the cleaning brush 53 are fixedly connected, and an elastic component for driving the connecting frame 51 to move is provided on the closed groove 41; the elastic component includes a threaded hole 58 opened on the closed groove 41 and communicating with the interior of the movable groove 55, and a spring 57 fixed to the top of the connecting frame 51, a butt ring 56 is fixed to the top of the spring 57, a threaded rod 59 is screwed in the threaded hole 58, and one end of the threaded rod 59 extends into the movable groove 55 and is rotatably connected to the top of the butt ring 56.

[0042] A positioning block 54 is fixed to one side of the connecting frame 51 , and a positioning groove for the positioning block 54 to slide is defined in the movable groove 55 .

[0043] Through the above technical solution:

[0044] When the pressure between the cleaning brush 53 and the solar panel 12 needs to be adjusted, the threaded rod 59 is rotated to engage with the threaded hole 58, and then the threaded rod 59 moves along the threaded hole 58 into the movable groove 55. At this time, the threaded rod 59 moves downward along the movable groove 55 to push the retaining ring 56 to move downward, and the retaining ring 56 moves to push the spring 57 and the connecting frame 51 to slide downward along the movable groove 55, and the connecting frame 51 moves downward to drive the positioning block 54 to slide downward along the positioning groove, so that the cleaning rod 52 slides down along the movable groove 55. The cleaning brush 53 is driven to move so that the cleaning brush 53 fits against the solar panel 12. The spring 57 is located between the retaining ring 56 and the connecting frame 51 to adjust the tension, that is, the pressure between the cleaning brush 53 and the solar panel 12 is adjusted synchronously, so that the cleaning brush 53 fits against the solar panel 12 but not too tightly. At the same time, the solar panel 12 can be cleaned once during the collection process in the collection box 11, and the solar panel 12 can be cleaned again during the sliding process out of the collection box 11, which is beneficial to the cleaning of the surface of the solar panel 12.
