Description

Technical Field

[0002] A photovoltaic (PV) mounting system is a structural system specifically designed to mount and support photovoltaic (PV) modules, such as solar panels. It is typically fixed to a vehicle roof or other flat surface to ensure the modules can stably and safely receive sunlight and convert it into electricity. PV mounting systems come in a variety of designs and structures to suit different installation environments and requirements. They not only provide the necessary support but often also feature adjustable angles, allowing the tilt of the PV modules to be adjusted according to the sun's position, maximizing solar energy capture efficiency. PV mounting systems also need to be durable and resistant to wind pressure to ensure stable operation of the PV system even in adverse weather conditions.

[0003] According to the patent document: CN119561460A, a photovoltaic panel bracket is disclosed, including an external component, including a support frame and a bracket frame arranged between the support frames; and a transmission component, including a fixed frame arranged on both sides of the support frame, a first connecting tube arranged inside the fixed frame and a transmission rod arranged at one end of the first connecting tube; and a wind pressure component, including a fixed rod arranged at one end of the fixed frame, a fixed ring arranged at one end of the fixed rod and an operating rod sleeved inside the fixed ring; and a rotating component, including an axis rod arranged at one end of the first connecting tube. The above invention will blow the wind pressure component through strong wind, and then drive the transmission component to rotate through the wind pressure component. When the transmission component rotates, the transmission component drives the rotating component to rotate, and the rotating component drives the outer bracket frame to rotate again, making it parallel, reducing the windward area, and preventing it from being damaged.

The bottom of the outer walls of the left and right groups of second rotating wheels 211 are all fitted to the bottom of the inner side of the groove 114 opened by the two side plates 113. The top ends of the two groups of columnar telescopic rods 29 extend to the top of the movable plate 21 and are rotatably connected to the photovoltaic panels 212 on all four sides. The middle parts of the front and rear sides of the photovoltaic panels 212 are fixedly connected to U-shaped blocks 213. The inner sides of the two U-shaped blocks 213 are fixedly connected to columnar cross sliding rods 214. The outer walls of the two columnar cross sliding rods 214 are slidably connected to the inner walls of the inclined slide grooves 28 opened by the two inclined slide groove blocks 27. When in use, first start the forward and reverse rotation of the motor 132 according to the direction of the sun. If the sun is facing the front side of the device, start the motor 132 in the reverse direction. The motor 132 starts to drive the turntable 133 to rotate and transmits the second turntable 135 through the transmission track 134 to drive the columnar transverse rod 136 to rotate. The rotation of the columnar transverse rod 136 drives the rotation of the side rotation rods 1311 at both ends. At this time, since the motor 132 is reversed, the two side rotation rods 1311 are driven to rotate backward, thereby driving the protective mechanism 3 as a whole to move backward on the top of the base 1 through the side rotation rod slide groove 1312, and no longer shielding the photovoltaic panel connecting frame 2; At the same time, when the guard mechanism 3 moves to the rear side as a whole, thereby driving the crawler 110 to reverse, the two crawler tracks 110 reverse and drive the two crawler connecting blocks 22 in the middle of the bottom to move forward, and the two crawler connecting blocks 22 move forward and drive the moving plate 21 to slide forward on the outer walls of the two second guide rods 112.

Since the moving plate 21 is moving forward, the rotating wheel 26 at the bottom of the columnar lifting rod 25 on the rear side of the moving plate 21 slides along the track to the top middle of the triangular block 116 on the top of the second stop plate 115, thereby making the rear column lifting rod 2 The inclined slide block 27 is pushed to move toward the top, and then the inclined slide block 27 on the rear side drives the columnar cross slide bar 214 on the rear side of the photovoltaic panel 212 to slide upward on the inner wall of the inclined slide bar 28, and the columnar cross slide bar 214 slides upward, thereby driving the photovoltaic panel 212 to flip upward. When the photovoltaic panel 212 flips and tilts to the direction of sunlight exposure, the second rollers 211 on the four sides of the bottom of the photovoltaic panel 212 slide forward along the grooves 114 opened by the two side plates 113. As the moving plate 21 slides forward and slides out of the grooves 114 opened by the side plates 113, the two sets of columnar telescopic rods 29 will also push the photovoltaic panel 212 upward along the top of the side plates 113 to move the entire photovoltaic panel 212 upward, so that the surface of the photovoltaic panel 212 is higher than the top of the base 1, thereby facilitating the photovoltaic panel 212 to better receive sunlight for power generation, thereby improving the power generation efficiency of the photovoltaic panel 212. When the sun is facing the rear side of this device, start the motor 132 to rotate forward, and the forward rotation of the motor 132 causes the above-mentioned structure to move in the opposite direction until the protective mechanism 3 is on the front side of the top of the base 1, the photovoltaic panel connecting frame 2 is as a whole on the rear side of the inner side of the base 1, and the inclination angle of the photovoltaic panel 212 is opposite to the inclination angle on the front side.

The top of the two groups of V-shaped rotating blocks 326 away from the C-shaped connecting cross bar 321 is fixedly connected to a V-shaped rotating block slider 327.The outer walls of the two groups of V-shaped rotating block sliders 327 are slidably connected to the inner walls of the two groups of arc-shaped slide plates 325. The inner sides of the two groups of expansion rods 329 are rotatably connected to the two rotating oblique rods 3210. The bottoms of the multiple groups of rotating oblique rods 3210 are rotatably connected to the rotating oblique rod bottom hinge blocks 3211. The bottoms of the two groups of rotating oblique rod bottom hinge blocks 3211 are fixedly connected to the cleaning roller connecting plates 3212. The inner sides of the bottoms of the two cleaning roller connecting plates 3212 are rotatably connected to the cleaning rollers 3213. The two cleaning rollers 3213 are rotatably connected to the inner sides of the bottoms of the two cleaning rollers. The bottom of the outer wall of 213 is in contact with both sides of the top of the photovoltaic panel 212. The connection between the two sets of V-shaped rotating blocks 326 and the expansion rod 329 is rotatably connected to the axial rotating rod 3214. The two sets of axial rotating rods 3214 are rotatably connected to the side away from the V-shaped rotating block 326. The two sets of axial rotating rods 3214 are rotatably connected to the two-way hinge blocks 3215. The middle part of the outer side of the two two-way hinge blocks 3215 is fixedly connected to the two-way hinge block sliders 324. The outer walls of the two two-way hinge block sliders 324 are slidably connected to the inner walls of the two slide blocks 322. When the protective mechanism 3 moves as a whole, the two second track connecting blocks 313 of the protective bottom plate 311 pull the two tracks 110 to move, thereby driving the photovoltaic panel connecting frame 2 to move as a whole in the opposite direction. When the protective mechanism 3 moves as a whole, at this time, the outer walls of the two cleaning rollers 3213 at the bottom are in contact with the surface of the photovoltaic panel 212, so that when the protective mechanism 3 moves as a whole, it will drive the cleaning rollers 3213 to slide on the surface of the photovoltaic panel 212, cleaning the surface of the photovoltaic panel 212, avoiding the accumulation of dust or debris on the surface of the photovoltaic panel 212 that affects the power generation efficiency. When the photovoltaic panel 212 flips over during the movement, the cleaning rollers 3213 can be connected to the cleaning rollers The rotation of the plate 3212 and the hinged block 3211 at the bottom of the rotating inclined rod enables the cleaning roller 3213 to always be in contact with the surface of the photovoltaic panel 212, and the position of the cleaning roller 3213 can be adjusted according to the flipping angle of the photovoltaic panel 212. At the same time, the V-shaped rotating block 326 and the expansion rod 329 cooperate with the axial rotating rod 3214 and the bidirectional hinged block 3215 to enable the cleaning roller 3213 to adaptively adjust according to the curvature of the photovoltaic panel 212 when moving on the surface of the photovoltaic panel 212, thereby maintaining a close contact between the cleaning roller 3213 and the surface of the photovoltaic panel 212. In addition, the second spring 323 can enable the cleaning roller 3213 to produce a certain degree of elastic deformation when subjected to pressure. During the movement of the protective mechanism 3, the moving blocks 3110 on the inner sides of the two reflective plate connecting side plates 314 are pushed by the columnar short rods 17. When the protective mechanism 3 moves toward the rear side, the two moving blocks 3110 are pushed by the front ends of the two columnar short rods 17 on the rear side, thereby causing the two moving blocks 3110 to move forward on the inner sides of the two reflective plate connecting side plates 314. The two moving blocks 3110 move forward, thereby causing the two angle rotation rods 3113 to slide on the inner walls of the two guide rotating plates 318 and causing the two guide rotating plates 318 to rotate toward the rear side, and the two angle rotation rods 3113 follow the two guide rotating plates. 318 rotates and rotates, thereby causing the reflective plate 3114 to flip backward, so that the bottom of the reflective plate 3114 and the top of the photovoltaic panel 212 form a V-shaped structure. When sunlight shines on the reflective plate 3114, the reflective plate 3114 can reflect the sunlight so that the sunlight can shine on a larger range of the photovoltaic panel 212, thereby increasing the illumination area of ​​the photovoltaic panel 212 and further improving the photoelectric conversion efficiency of the photovoltaic panel 212. At the same time, the V-shaped structure can also reduce the wind resistance of the reflective plate 3114, thereby reducing the wind resistance and the impact of wind on the photovoltaic bracket and the photovoltaic panel 212. When the protective mechanism 3 moves to the front side, the above structure moves in the opposite direction. At this time, the two moving blocks 3110 are pushed by the rear ends of the two front columnar short rods 17, so that the two moving blocks 3110 move toward the rear side on the inner side of the two reflective plate connecting side plates 314. The two moving blocks 3110 move toward the rear side, driving the two angle rotation rods 3113 to slide on the inner walls of the two guide rotating plates 318 and causing the two guide rotating plates 318 to rotate toward the front side, and the two angle rotation rods 3113 rotate along with the rotation of the two guide rotating plates 318, thereby causing the reflective plate 3114 to flip toward the front side. In addition, the setting of the spring 315 can provide a reset force after the moving block 3110 moves, so that when the columnar short rod 17 no longer pushes the moving block 3110, the moving block 3110 can be reset under the action of the spring 315, thereby driving the reflective plate 3114 to reset.

[0023] The working principle of the present invention is as follows: the forward and reverse rotation of the motor 132 is started according to the direction of the sun. If the sun is facing the front side of the device, the motor 132 is started to reverse. The motor 132 starts to drive the turntable 133 to rotate and transmits the second turntable 135 through the transmission track 134 to drive the columnar transverse rod 136 to rotate. The rotation of the columnar transverse rod 136 drives the rotation of the side rotation rods 1311 at both ends. At this time, since the motor 132 is reversed, the two side rotation rods 1311 are driven to rotate backward, thereby pushing the protective mechanism columnar block 3115 fixed on the left and right sides of the protective bottom plate 311 through the side rotation rod slide groove 1312 to follow the rotation of the side rotation rod 1311 and move backward, so that the protective mechanism 3 moves backward as a whole. When the two second crawler connecting blocks 313 of the protective bottom plate 311 pull the two crawlers 110 to move, when the protective mechanism 3 moves backward as a whole and drives the crawler 110 to reverse, the two crawler 110 reverses and drives the two crawler connecting blocks 22 in the middle of the bottom to move forward, and the two crawler connecting blocks 22 move forward and drive the movable plate 21 to slide forward on the outer walls of the two second guide rods 112. At this time, since the photovoltaic panel 212 is slidably connected to the inner wall of the inclined slot 28 opened by the inclined slot block 27 through the columnar cross sliding rod 214 on the inner side of the U-shaped block 213, and the inclination angle of the inclined slot 28 is opposite to the moving direction of the movable plate 21, when the movable plate 21 moves forward, it will drive the two inclined slot blocks 27 to move forward. The movable plate 21 moves forward, so the wheel 26 at the bottom of the columnar lifting rod 25 on the rear side of the movable plate 21 slides along the track to the top middle of the triangular block 116 on the top of the second abutment plate 115, thereby making the rear columnar lifting rod 25 push the inclined slide block 27 to move to the top, and then the inclined slide block 27 on the rear side drives the columnar cross slide rod 214 on the rear side of the photovoltaic panel 212 to slide upward on the inner wall of the inclined slide groove 28 through the inclined slide groove 28, and the columnar cross slide rod 214 slides upward and drives the photovoltaic panel 212 to flip upward. When the photovoltaic panel 212 flips and tilts to the direction of sunlight, the second wheels 211 on the four sides of the bottom of the photovoltaic panel 212 slide forward along the grooves 114 opened by the two abutment plates 113. When the protective mechanism 3 slides forward and out of the groove 114 provided on the side plate 113, at this time, the two sets of columnar telescopic rods 29 will also push the photovoltaic panel 212 to move upward as a whole along the top of the side plate 113, so that the surface of the photovoltaic panel 212 is higher than the top of the base 1, thereby facilitating the photovoltaic panel 212 to better receive sunlight for power generation, thereby improving the power generation efficiency of the photovoltaic panel 212. When the protective mechanism 3 moves as a whole, at this time, the outer walls of the two cleaning rollers 3213 at the bottom are in contact with the surface of the photovoltaic panel 212, so that when the protective mechanism 3 moves as a whole, it will drive the cleaning rollers 3213 to slide on the surface of the photovoltaic panel 212, cleaning the surface of the photovoltaic panel 212, and avoiding the accumulation of dust or debris on the surface of the photovoltaic panel 212 that affects the power generation efficiency.When the photovoltaic panel 212 flips during movement, the cleaning roller 3213 can rotate the cleaning roller connecting plate 3212 and the hinge block 3211 at the bottom of the rotating inclined rod, so that the cleaning roller 3213 can always fit the surface of the photovoltaic panel 212, and adjust the position of the cleaning roller 3213 according to the flipping angle of the photovoltaic panel 212. At the same time, the V-shaped rotating block 326 and the expansion rod 329 cooperate with the axial rotating rod 3214 and the two-way hinge block 3215 to enable the cleaning roller 3213 to move on the surface of the photovoltaic panel 212. It can be adaptively adjusted according to the curvature of the photovoltaic panel 212, keeping the cleaning roller 3213 in close contact with the surface of the photovoltaic panel 212. In addition, the action of the second spring 323 can make the cleaning roller 32 When the protective mechanism 3 is subjected to pressure, a certain elastic deformation is generated. During the movement of the protective mechanism 3, the moving blocks 3110 on the inner sides of the two reflective plate connecting side plates 314 are pushed by the columnar short rods 17. When the protective mechanism 3 moves toward the rear side, the two moving blocks 3110 are pushed by the front ends of the two columnar short rods 17 on the rear side, thereby causing the two moving blocks 3110 to move forward on the inner sides of the two reflective plate connecting side plates 314. The two moving blocks 3110 move forward, thereby causing the two angle rotation rods 3113 to slide on the inner walls of the two guide rotating plates 318 and causing the two guide rotating plates 318 to rotate toward the rear side. The two angle rotation rods 3113 rotate along with the rotation of the two guide rotating plates 318, thereby causing the reflective plate 3114 to move toward the rear side. The bottom of the reflective plate 3114 and the top of the photovoltaic panel 212 form a V-shaped structure. When sunlight shines on the reflective plate 3114, the reflective plate 3114 can reflect the sunlight so that the sunlight can shine on the photovoltaic panel 212 in a wider range, thereby increasing the illumination area of ​​the photovoltaic panel 212 and further improving the photoelectric conversion efficiency of the photovoltaic panel 212. At the same time, the V-shaped structure can also reduce the wind resistance of the reflective plate 3114, reduce the wind resistance, and reduce the impact of the wind on the photovoltaic bracket and the photovoltaic panel 212. When the sun is facing the rear side of the device, the motor 132 is started to rotate forward, and the forward rotation of the motor 132 causes the above-mentioned structure to do the opposite movement together until the protective mechanism 3 is at the front side of the top of the base 1, and the photovoltaic The panel connecting frame 2 is entirely on the rear side of the inner side of the base 1, and the inclination angle of the photovoltaic panel 212 is opposite to the inclination angle on the front side. When the protective mechanism 3 moves to the front side, the above structure moves in the opposite direction. At this time, the two moving blocks 3110 are pushed by the rear ends of the two columnar short rods 17 on the front side, so that the two moving blocks 3110 move to the rear side on the inner side of the two reflective plate connecting side plates 314. The two moving blocks 3110 move to the rear side, driving the two angle rotating rods 3113 to slide on the inner walls of the two guide rotating plates 318 and causing the two guide rotating plates 318 to rotate to the front side, and the two angle rotating rods 3113 rotate along with the rotation of the two guide rotating plates 318, thereby causing the reflective plate 3114 to flip to the front side. When photovoltaic power generation is not needed,At this time, the photovoltaic panel connection frame 2 and the protective mechanism 3 are restored to their original positions on the top and inside of the base 1. At this time, the protective mechanism 3 is on the top of the photovoltaic panel connection frame 2 to shield the entire photovoltaic panel connection frame 2 to prevent dust or debris from falling on the surface of the photovoltaic panel 212, causing contamination on the surface of the photovoltaic panel 212 and affecting the power generation efficiency and service life of the photovoltaic panel 212.
