[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a wall-embedded solar photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation utilizes the photovoltaic effect at semiconductor interfaces to directly convert sunlight into electricity. It primarily consists of three main components: solar panels (modules), controllers, and inverters, with the majority of these components comprised of electronic components. Solar cells are connected in series and then encapsulated to form large-scale solar modules, which, when combined with components such as power controllers, form photovoltaic power generation devices. However, wall-embedded solar photovoltaic installations are difficult in extreme environments such as deserts and snowstorms. Furthermore, impurities such as dust and falling snow can cover the panels, significantly reducing power generation efficiency and resulting in wasted resources.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] For example 1, please refer to Figure 1-Figure 5 , a wall-embedded solar photovoltaic power generation device, comprising: The installation frame 100 is embedded in the wall. The installation frame 100 is provided to facilitate installation and removal of the entire device on the wall, and also facilitate subsequent maintenance and replacement of accessories; Photovoltaic panel 200, which is hinged to the inside of the mounting frame 100 via a rotating shaft, and a connecting block 400 is fixed to the bottom of the photovoltaic panel 200; Triangular block 300, which is fixed inside the mounting frame 100. The inclined surface of triangular block 300 is rotatably connected to threaded barrel 500. The internal threads of threaded barrel 500 are connected to threaded block 1 600. A connecting rod 700 is fixed to the side of threaded block 1 600. Connecting rod 700 is hinged to connecting block 400. Two fixing blocks 1 801 and 2 802 for support are fixed on both sides of the photovoltaic panel 200. The interiors of the two fixing blocks 802 are penetrated and rotatably connected with a bidirectional screw rod 803. The two bidirectional screw rods 803 are threadedly connected with a thread block 2 804. A roller brush 805 is rotatably connected between the two thread blocks 804. The size of the thread block 204 is the same as the depth and width of the internal texture of the bidirectional screw rod 803, so that the thread block 204 can move back and forth along the texture on the bidirectional screw rod 803, thereby allowing the roller brush 805 to reciprocate on the photovoltaic panel 200, and the bristle part of the roller brush 805 is in contact with the photovoltaic panel. 200 is fully in contact, so that when the roller brush 805 rotates, the snow and dust on the photovoltaic panel 200 are completely removed. The ends of the two bidirectional screw rods 803 are connected to the turbine 1 807 through the telescopic universal flexible shaft 806. The telescopic universal flexible shaft 806 is set so that when the photovoltaic panel 200 rotates, the telescopic universal flexible shaft 806 is driven to stretch, bend and rotate, thereby transmitting the power of the turbine 1 807 to the bidirectional screw rod 803, so that the roller brush 805 can reciprocate on the photovoltaic panel 200, and the turbine 807 is rotatably connected to the inside of the installation frame 100. The turbine 1 807 is transmission-connected to the threaded block 1 600 through a transmission member; The transmission components include a first worm 808, a turbine 1 809, a second worm 8010, a gear 1 8011, a movable rod 8012, and a first rack 8013. One side of the movable rod 8012 is hinged to the threaded block 1 600, and the other side of the movable rod 8012 is hinged to the first rack 8013. The gear 1 8011 is fixedly connected to the second worm 8010. The top of the first rack 8013 is meshed with the gear 1 8011. The top of each turbine 1 809 is fixedly connected to the first worm 808. The two ends of the second worm 8010 are respectively meshed with two turbine 1 809. The side of each first vortex rod 808 is engaged with two turbines 807, and one end of turbine 1 807 is fixedly connected to the mounting assembly 900. The middle two sides of the second vortex rod 8010 are fixedly connected to gear 2 8014. The top of the first vortex rod 808 is rotatably connected to the mounting frame 100 through a rotating shaft, and the two sides of the second vortex rod 8010 are rotatably connected to the mounting frame 100 through a rotating shaft. A transmission part is provided so that the angle of the photovoltaic panel 200 can be adjusted by adjusting the threaded barrel 500, so that the photovoltaic panel 200 can be changed according to different sunlight exposure angles, thereby improving the power generation efficiency of the device.

[0019] When in use, the threaded barrel 500 is rotated to drive the connecting rod 700 to move downward, so that the movable rod 8012 moves downward, and the first rack 8013 moves backward along the direction of the sliding groove in the installation frame 100, driving the gear 1 8011 to rotate, so that the second vortex rod 8010 rotates, driving the two turbines 1 807 to rotate, so that the two first vortex rods 808 rotate, so that the two turbines 2 809 rotate, thereby rotating the two telescopic universal flexible shafts 806, driving the two bidirectional screw rods 803 to rotate, so that the threaded block 2 804 moves along the grain, and the roller brush 805 reciprocates on the surface of the photovoltaic panel 200, so that the dust and snow on the surface of the photovoltaic panel 200 are cleaned. In addition, it reduces the impact of dust and falling snow on the coverage of the photovoltaic panel 200 in extreme environments such as deserts and blizzards, improves the power generation efficiency of the photovoltaic panel 200, and saves labor. At the same time, when the connecting rod 700 moves downward, the photovoltaic panel 200 rotates downward along the axis, so that the angle of the photovoltaic panel 200 can be adjusted, so that the photovoltaic panel 200 can receive sunlight to the greatest extent, thereby improving the power generation efficiency of the device. When the angle of the photovoltaic panel 200 changes, the length and angle of the telescopic universal flexible shaft 806 will also change, so that the power generated by the rotation of the turbine 2 809 is transmitted to the bidirectional screw 803, thereby not affecting the reciprocating motion of the roller brush 805 on the photovoltaic panel 200.

[0020] For example 2, please refer to Figures 1-6, Based on the first embodiment, the mounting assembly 900 includes a gear three 901, a second rack 902, a third rack 903, and a slider 904. One end of the gear three 901 is fixedly connected to the turbine one 807. One side of the gear three 901 is meshed with the second rack 902, and the other side of the gear three 901 is meshed with the third rack 903. The top of the second rack 902 is slidably connected to the slider 904, and the bottom of the third rack 903 is slidably connected to the slider 904. Slide grooves are provided at the upper and lower ends of the wall so that the two sliders 904 can move up and down in the slide grooves, so that the mounting frame 100 can be fixed to the wall, achieving the effect of fixing the entire device on the wall. The slider 904 is slidably connected to the mounting frame 100 through the slide groove one provided inside the mounting frame 100. A pin hole one is provided inside each slider 904 and at the top of each second rack 902, and a pin hole two is provided at the bottom of each third rack 903. When the angle of the photovoltaic panel 200 is adjusted to the minimum, the second rack 902 and the third rack 903 will not slide out of the slide groove. A magnet is fixed to the bottom of the wall slide groove. When the slider 904 moves to the top, the pin is pulled out, so that the slider 904 is magnetically fixed to the wall slide groove, so that the position of the slider 904 is not changed when the angle of the photovoltaic panel 200 is changed, making the installation and use of the device more convenient. A magnet is provided so that the slider 904 can be adsorbed to the top of the wall slide groove when rising or falling, thereby playing a better fixing role.

[0021] When in use, based on the first embodiment, when the turbine 1 807 is in the rotating state, it can drive the gear 3 901 to rotate, so that the slider 904 slides into the interior of the slide groove. At this time, the pin is pulled out to separate the slider 904 from the second rack 902 and the third rack 903. A magnet is provided inside the wall slide groove so that the slider 904 is magnetically fixed to the wall slide groove after separation. At the same time, the slider 904 does not follow the movement of the rack 2 802 and the rack 3 804. Therefore, when the angle of the photovoltaic panel 200 is changed, the second rack 902 and the third rack 903 move up and down along the slide groove without changing the position of the slider 904, so that the installation frame 100 can be fixed to the wall while the angle of the photovoltaic panel 200 can be adjusted at will, making the installation and use of the device more convenient. When the device is disassembled, insert The latch fixes the slider 904 to the second rack 902 and the third rack 903, rotates the threaded cylinder 500, drives the connecting rod 700 to move downward, moves the movable rod 8012 downward, moves the first rack 8013 backward along the direction of the slide groove in the installation frame 100, drives the gear 1 8011 to rotate, rotates the second vortex rod 8010, drives the two first vortex rods 808 to rotate, rotates the two turbine twos 809, rotates the gear three 901, moves the second rack 902 downward, moves the third rack 903 upward, and disengages the slider 904 from the wall slide groove, thereby separating the installation frame 100 from the wall, and then removes the triangular block 300, making it easier to remove the installation component 900, the reflection component 1000, the photovoltaic panel 200 and the installation frame 100.

[0022] For example three, please refer to Figure 1-Figure 7On the basis of the first and second embodiments, the reflective assembly 1000 passes through and is fixedly assembled inside the mounting frame 100. The reflective assembly 1000 includes a reflector 1001, a fourth gear 1002, and a fourth rack 1003. There are two fourth racks 1003. One side of each second gear 8014 is meshed with the fourth rack 1003. One end of each fourth gear 1002 is rotatably connected to the reflector 1001 through a rotating shaft. The side of each fourth rack 1003 away from the second gear 8014 is meshed with the fourth gear 1002. The second gear 8014 is provided so that the power of the second worm 8010 can be transmitted to the fourth rack 1003. When the second worm 8010 rotates, it drives the two second gears 8014 to rotate, causing the fourth rack 1003 to move up and down, thereby changing the reflector 1 001, so that the reflector 1001 changes its angle along with the photovoltaic panel 200, the reflector 1001 is rotatably connected to the wall through a spherical groove opened on the wall surface, and the fourth rack 1003 is slidably connected to the wall through a slide groove three opened inside the wall, and a reflective component 1000 is set, so that when the photovoltaic panel 200 changes its angle, the reflective component 1000 can also change its angle, thereby increasing the sunlight reflected to the photovoltaic panel 200, improving the power generation efficiency of the entire device, and making full use of resources. A spherical groove is opened on the wall surface, so that the reflector 1001 can rotate in the spherical groove without being affected by the wall, and the reflector 1001 is set, so that sunlight shines on the reflector 1001, and then reflects on the photovoltaic panel 200, so that more sunlight can shine on the photovoltaic panel 200, thereby improving the power generation efficiency of the device.

[0023] During use, based on the first and second embodiments, after the installation of the installation frame 100 is completed, the threaded cylinder 500 is rotated to drive the connecting rod 700 to move downward, so that the movable rod 8012 moves downward, and the first rack 8013 moves backward along the third direction of the slide groove in the installation frame 100, driving the gear 1 8011 to rotate, so that the second worm rod 8010 rotates, driving the two gear 2 8014 to rotate, so that the two fourth racks 1003 move up and down, and driving the two gear 4 1002 to rotate, thereby causing the reflector 1001 to rotate along the axis direction, so that the reflector 1001 rotates with the photovoltaic panel 200. When the angle of sunlight changes, the angle of the photovoltaic panel 200 is adjusted to the optimal angle. At the same time, the reflector 1001 can also be rotated to a suitable angle, thereby increasing the area of sunlight reflected to the photovoltaic panel 200, so that the photovoltaic panel 200 receives sunlight to the greatest extent. At the same time, a spherical groove is provided on the surface of the wall, so that the reflector 1001 rotates in the spherical groove without being affected by the wall.
