[0037] Embodiment

[0038] Please refer to Figure 1-18 , the present invention provides the following technical solution: a highly adaptable photovoltaic bracket with time-sharing adjustment, including a photovoltaic panel bracket 3, the photovoltaic panel bracket 3 is inclined, a solar photovoltaic panel is installed at the top of the photovoltaic panel bracket 3, a ball socket is installed in the middle of the bottom of the photovoltaic panel bracket 3, a universal ball that can freely roll is arranged inside the ball socket, a base 1 is installed at the bottom of the universal ball, both sides below the base 1 are connected to electric cylinders 2 through universal joints, and the tops of the electric cylinders 2 are connected to both sides of the bottom of the photovoltaic panel bracket 3 through another universal joint. By controlling the relative expansion and contraction of the two electric cylinders 2 on both sides, the photovoltaic panel bracket 3 can deflect following the movement of the sun during the day, thereby improving the power generation efficiency of the photovoltaic power generation.

[0039] A frame 4 is installed at the top peripheral edge of the photovoltaic panel bracket 3. A sewage concave opening 5 is opened at the bottom of the lower side of the frame 4. A shielding component is arranged below the inside of the frame 4. A scraping component is arranged above the inside of the frame 4 and attached to the top of the shielding component. Both the shielding component and the scraping component operate with the volume change of a heat-expandable fluid as the driving source. Among them, the scraping component is used to scrape the sundries on the top of the shielding component and discharge them from the sewage concave opening 5, and the shielding component is used to open during the high temperature in the day to expose the solar photovoltaic panel and close during the low temperature at night to shield the solar photovoltaic panel.

[0040] Specifically, the shielding component includes two first transparent heat-receiving tubes 11, the two first transparent heat-receiving tubes 11 are respectively installed on both sides of one side of the frame 4, first concave mirror reflecting condensers 14 are installed below the two first transparent heat-receiving tubes 11, first pistons 12 are arranged inside the two first transparent heat-receiving tubes 11, push-pull rods 13 are installed in the middle of one ends of the two first pistons 12 facing the photovoltaic panel bracket 3, slots are opened at the upper and lower sides of the bottom of the frame 4, racks 10 are slidably connected above the inside of the two slots on both sides, one ends of the two push-pull rods 13 respectively penetrate through the photovoltaic panel bracket 3 and are installed at one ends of the two racks 10 on both sides, and heat-expandable fluids are filled in the cavities between the other ends of the two first pistons 12 and the two first transparent heat-receiving tubes 11. After the temperature inside the first transparent heat-receiving tube 11 rises, when the volume of the heat-expandable fluid suddenly becomes larger, the first piston 12 can be pushed.

[0041] The above-mentioned heat-expandable fluid refers to a fluid that expands rapidly in volume when its temperature rises under sunlight irradiation, thereby serving as a power source for driving the first piston 12. Since this power source does not require additional consumption, it is more environmentally friendly and energy-saving, which is very consistent with the concept of photovoltaic clean energy. The above-mentioned heat-expandable fluid can be mercury or a fluid with similar heat-expandable physical properties.

[0042] Further, a plurality of shaft rods 6 are evenly and rotatably connected in parallel inside the frame 4. Both ends of the shaft rods 6 extend into the internal slots on both sides and are respectively installed with gears 9. The tops of the gears 9 are respectively meshed with the bottoms of the racks 10 on both sides. Flaps 7 are installed on the outer parts of the shaft rods 6. There is a gap between the lower end of the flap 7 and the inner side of the frame 4, and the higher end of the flap 7 is in contact with the inner side of the frame 4.

[0043] When the first piston 12 is pushed, it drives the push rod 13 to move, thereby driving the rack 10 to move. Then the gear 9 can rotate, and thus the flap 7 is driven to deflect by the shaft rod 6. At the same time, it is also necessary to set the moving distance of the rack 10 to only be able to drive the gear 9 to rotate 90°, so as to ensure the stable opening of the flap 7. After the flap 7 is opened, the internal solar photovoltaic panel can be exposed, and then photovoltaic power generation can be realized. During the operation throughout the day, since the temperature is always relatively high, the position of the flap 7 and the position after the scraping cross bar 16 moves can be maintained.

[0044] Further, balls 8 that can roll freely are embedded on both sides of the lower end of the flap 7.

[0045] Specifically, the scraping assembly includes a scraping cross bar 16. The scraping cross bar 16 is arranged inside the frame 4 and on top of the shielding assembly. The thickness of the scraping cross bar 16 is the same as the width of the gap reserved between the lower end of the flap 7 and the inner side of the frame 4. A roller 17 is rotatably connected to one side of the bottom of the scraping cross bar 16, and a cleaning strip 18 is installed on the other side. The bottoms of the roller 17 and the cleaning strip 18 are flush with the top of the flap 7. A slider 15 is installed at one end of the scraping cross bar 16. A chute is opened on one inner wall of the frame 4, and a first through groove communicating with the outside is opened at the top of the chute. The outer part of the slider 15 is slidably connected inside the chute.

[0046] Through the settings of the roller 17 and the balls 8, the friction between the flap 7 and the scraping cross bar 16 can be reduced, promoting the smooth operation between the structures.

[0047] Further, at the top of the first through groove, the top of the frame 4 is provided with an action tube 19. A plunger 20 is slidably connected to the higher end inside the action tube 19. A second through groove communicating with the outside is opened at the bottom of the action tube 19. A connecting rod is installed at the bottom of the plunger 20. The bottom of the connecting rod sequentially passes through the second through groove and the first through groove and is installed on the top of the slider 15. A U-shaped tube 21 is installed at the top port of the action tube 19. Another port of the U-shaped tube 21 is installed with a second transparent heat receiving tube 22. On the other side of the frame 4, a second concave mirror reflecting and condensing mirror 25 is installed below the second transparent heat receiving tube 22. Through the settings of the first concave mirror reflecting and condensing mirror 14 and the second transparent heat receiving tube 22, more sunlight can be converged and irradiated on the transparent heat receiving tube, thereby ensuring the stable operation of the device. A second piston 23 is slidably connected to the lower end inside the second transparent heat receiving tube 22. A metal hose 24 that can move freely is arranged in the communication cavity between the action tube 19, the U-shaped tube 21 and the second transparent heat receiving tube 22. Two ends of the metal hose 24 are respectively connected to one ends of the plunger 20 and the second piston 23. Another heat-expandable fluid is filled in the cavity between the other end of the second piston 23 and the second transparent heat receiving tube 22.

[0048] The above-mentioned heat-expandable fluid refers to a fluid that, when irradiated by the sun, its volume will expand rapidly after the temperature rises, thereby serving as a power source for driving the first piston 12. Since this power source does not require additional consumption, it is more environmentally friendly and energy-saving, and is very consistent with the concept of photovoltaic power generation clean energy. The above-mentioned heat-expandable fluid can be mercury or a fluid with similar heat-expandable physical properties.

[0049] When the second piston 23 is pushed, it further pushes the plunger 20 to move inside the action tube 19 through the metal hose 24, and then drives the slider 15 to move through the connecting rod, thereby driving the scraping cross bar 16 to move. Since the bottom of the scraping cross bar 16 has a cleaning strip 18, the surface of the baffle 7 can be cleaned first until the scraping cross bar 16 moves to the lower side of the frame 4.

[0050] Further, a sloping plate 26 is installed on the lower side inside the frame 4, and the shaft rods 6 all pass above the sloping plate 26. The sundries scraped by the scraping cross bar 16 between the sewage notch 5 and the baffle 7 can be smoothly discharged from the sewage notch 5 under the guiding action of the sloping plate 26, which is more convenient to use. At the same time, it can also prevent sand and wind from entering the solar photovoltaic panel from the sewage notch 5.

[0051] Working principle of this embodiment: According to the local geographical location and time, by controlling the relative expansion and contraction of the two electric cylinders 2 on both sides, the photovoltaic panel support 3 can deflect following the movement of the sun during the day, thereby improving the efficiency of photovoltaic power generation. In the morning, the photovoltaic panel support 3 deflects eastward to face the sun. After being irradiated by the sun for a period of time, due to the increase in the temperature inside the first transparent heat-receiving tube 11 and the second transparent heat-receiving tube 22, after the volume of the heat-expandable fluid expands sharply when heated, it can respectively push the first piston 12 and the second piston 23, and then drive the shutter 7 or the scraping crossbar 16 to act. At this time, due to the obstruction of the upper scraping crossbar 16, the shutter 7 cannot deflect. Therefore, in the morning, the scraping crossbar 16 moves first. Specifically, the second piston 23 is pushed, and then the plunger 20 is pushed through the metal hose 24 to move inside the action tube 19, and then the slider 15 is driven to move through the connecting rod, thereby driving the scraping crossbar 16 to move. Since the bottom of the scraping crossbar 16 has a cleaning strip 18, the surface of the shutter 7 can be cleaned first until the scraping crossbar 16 moves to the lower side of the frame 4. At this time, the cleaned debris can be discharged from the sewage notch 5. When the scraping crossbar 16 moves to the gap between the shutter 7 and the frame 4, due to the loss of the obstruction of the scraping crossbar 16, the shutter 7 can deflect. Specifically, the first piston 12 is pushed, and then the push rod 13 is driven to move, thereby driving the rack 10 to move. Then the gear 9 can rotate, and the shutter 7 is driven to deflect through the shaft rod 6. At the same time, it is also necessary to set that the moving distance of the rack 10 can only drive the gear 9 to rotate 90°, so as to ensure the stable opening of the shutter 7. After the shutter 7 is opened, the internal solar photovoltaic panel can be exposed, and then photovoltaic power generation can be realized. During the operation process of the whole day, due to the high temperature all the time, the positions of the shutter 7 and the scraping crossbar 16 after movement can be maintained. When it is night, due to the temperature drop, the volume of the heat-expandable fluid returns to its original state. At this time, under the action of negative pressure, the shutter 7 and the scraping crossbar 16 can be driven to act in the reverse direction. At this time, due to the obstruction of the deflected shutter 7, the scraping crossbar 16 cannot move. Therefore, at this time, the shutter 7 can first deflect to restore its original state. Then, after the shutter 7 is in place, the scraping crossbar 16 can restore its original state. Through the above design, this photovoltaic support can be adjusted in different time periods, that is, it automatically opens when irradiated by the sun at high temperature during the day and automatically closes at low temperature at night. Such a design avoids the problem that dew condenses on the solar photovoltaic panel at night to form light spots, thereby affecting the service life, and no additional fossil energy is required, making it more energy-saving and environmentally friendly.
