[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0026] Example 1

[0027] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a photovoltaic bracket that is easy to adjust. An adjustment component 100 is set to automatically adjust the angle of the photovoltaic panel 202 in the photovoltaic component 200 to adapt to changes in the direct angle of the sun and improve the utilization rate of the photovoltaic panel 202.

[0028] Specifically, the adjustment component 100 includes a base frame 101, a connecting hole 102 is provided on the top of the base frame 101, an adjustment shell 103 is provided on the side of the base frame 101, the adjustment shell 103 is slidably connected to the base frame 101, an electric push rod 104 is provided at the bottom of the adjustment shell 103, a connecting plate 105 is provided on the top of the electric push rod 104, a transmission component 106 is provided inside the adjustment shell 103, an unlocking component 107 is provided on the side of the adjustment shell 103, the unlocking component 107 connects the adjustment shell 103 with the transmission component 106, and a positioning through hole 108 is provided through the outer wall of the adjustment shell 103.

[0029] The photovoltaic assembly 200 includes a rotating frame 201, a photovoltaic panel 202 is arranged on the top of the rotating frame 201, wind and sand protection components 203 are arranged on the top and bottom of the rotating frame 201, a locking component 204 is arranged on the side of the wind and sand protection component 203, and a gear 205 is arranged on the side of the rotating frame 201. There are multiple photovoltaic assemblies 200.

[0030] Both ends of the rotating frame 201 pass through the connecting holes 102 , and the gear 205 is disposed at one end of the rotating frame 201 close to the adjusting housing 103 .

[0031] In summary, multiple photovoltaic components 200 are connected to the transmission component 106 in the adjustment component 100 through the gear 205 on the side of the rotating frame 201. When the angle of the photovoltaic panel 202 needs to be adjusted, the electric push rod 104 will push the adjustment shell 103 to slide, and the transmission component 106 connected to the adjustment shell 103 will also slide. The transmission component 106 drives the gear 205 to rotate, thereby driving the rotating frame 201 to rotate, and finally driving the photovoltaic panel 202 to rotate, automatically adjusting the angle of the photovoltaic panel 202.

[0032] Example 2

[0033] Reference Figure 1 to Figure 5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that, when encountering extreme weather such as strong winds, the unlocking component 107 will disconnect the adjustment shell 103 from the transmission component 106, and the photovoltaic assembly 200 will rotate with the wind direction to reduce the windward area of ​​the photovoltaic panel 202, reduce the load on the bracket 107i, and protect the bracket 107i from being damaged by strong winds.

[0034] Specifically, the transmission component 106 includes a rack 106a arranged on the inner wall of the adjusting shell 103, the rack 106a is slidably connected to the adjusting shell 103, a key slot 106b is provided on the side of the rack 106a, and the adjusting shell 103 and the rack 106a are connected by a key during normal operation, a friction plate 106c is provided at the bottom of the rack 106a, the friction plate 106c provides friction for the rack 106a, resists the gravity of the rack 106a, and makes the rack 106a slide smoothly inside the adjusting shell 103, and the rack 106a is meshed with the gear 205 on the side of the photovoltaic component 200 rotating frame 201.

[0035] Furthermore, the unlocking component 107 includes a rotating wheel 107a arranged on the outer wall of the adjusting shell 103, a limiting plate 107b is arranged on the side of the rotating wheel 107a, and first elastic members 107c are arranged on both sides of the limiting plate 107b. A fixed plate 107d is arranged on the side of the first elastic member 107c away from the limiting plate 107b. The first elastic member 107c is in a compressed state and will apply pressure to the limiting plate 107b from both sides, so that the rotating wheel 107a is stationary and cannot rotate. A wind plate 107e is provided on the side of the wheel 107a away from the adjusting shell 103, and a pull rope 107f is provided at the bottom of the rotating wheel 107a. When encountering extremely windy weather, the strong wind will exert thrust on the wind plate 107e, no matter the wind blows from front to back or from back to front, as long as the wind is strong enough, the thrust exerted on the wind plate 107e exerts a torque on the rotating wheel 107a, which overcomes the pressure of the first elastic member 107c on the rotating wheel 107a, and will drive the rotating wheel 107a to rotate.

[0036] Furthermore, a square key 107g is provided at one end of the pull rope 107f away from the rotating wheel 107a, and a guide wheel 107h is provided on the side of the pull rope 107f. The guide wheel 107h guides the direction of the pull rope 107f. The rotation of the rotating wheel 107a will reel up the pull rope 107f, exert tension on the square key 107g to drive the square key 107g to slide, and a bracket 107i is provided on the side of the guide wheel 107h. The bracket 107i is arranged on the side of the adjustment shell 103. The square key 107g passes through the positioning through hole 108, and one end of the square key 107g passing through the positioning through hole 108 is inserted into the key slot 106b. When working normally, the square key 107g The key 107g connects the adjusting shell 103 and the rack 106a. The sliding of the adjusting shell 103 will drive the rack 106a to slide. When encountering strong winds, the wind force drives the wheel 107a to rotate, reeling in the pull rope 107f, pulling out the square key 107g, cutting off the connection between the adjusting shell 103 and the rack 106a, and the friction plate 106c set at the bottom of the rack 106a balances the gravity of the rack 106a itself, so that the rack 106a slides smoothly in the adjusting shell 103. At this time, the photovoltaic module 200 is unlocked, and the photovoltaic module 200 will rotate with the wind direction, reducing the windward area and reducing the thrust of the wind on the photovoltaic bracket.

[0037] In summary, when the invention works normally, the adjusting shell 103 is connected to the rack 106a through the square key 107g, and the rack 106a will slide with the sliding of the electric push rod 104. When encountering strong winds, the rotating wheel 107a will be affected by the strong wind to rotate the winding rope 107f, and the rope 107f will pull the square key 107g out of the rack 106a, so that the photovoltaic component 200 is unlocked, and the friction plate 106c set at the bottom of the rack 106a balances the gravity of the rack 106a itself, so that the rack 106a slides smoothly in the adjusting shell 103, and the photovoltaic component 200 will rotate with the wind direction, reduce the windward area, reduce the thrust of the wind on the photovoltaic bracket, and protect the photovoltaic bracket from being damaged by strong winds.

[0038] Example 3

[0039] Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that, during normal operation, the locking component 204 will prevent the wind and sand protection component 203 from extending to block the photovoltaic panel 202. When strong wind drives the photovoltaic assembly 200 to rotate rapidly, the wind and sand protection component 203 on the photovoltaic assembly 200 will extend to protect the surface of the photovoltaic panel 202 to prevent the wind and sand from scratching the photovoltaic panel 202.

[0040] Specifically, the wind and sand protection component 203 includes an outer shell 203a arranged on the outer wall of the rotating frame 201, the inner wall of the outer shell 203a is provided with a rotating shaft 203b, the outer wall of the rotating shaft 203b is provided with a windproof cloth 203c, and the side of the windproof cloth 203c is provided with a windward plate 203d. When encountering strong wind, the windward plate 203d will be subjected to the thrust exerted by the strong wind, and the side of the windward plate 203d is provided with a slider 203e, the top of the slider 203e is magnetic, and the windproof cloth 203c is wrapped around the outer wall of the rotating shaft 203b.

[0041] Furthermore, the locking component 204 includes a protective shell 204a arranged on the outer wall of the rotating frame 201, the inner wall of the protective shell 204a is provided with a sliding rod 204b, the outer wall of the sliding rod 204b is provided with an L-shaped top plate 204d, the L-shaped top plate 204d can slide on the outer wall of the sliding rod 204b, the bottom of the L-shaped top plate 204d is provided with a second elastic member 204c, the second elastic member 204c is in a compressed state, and a thrust is applied to the L-shaped top plate 204d, and a locking plate 204e is provided on the top of the L-shaped top plate 204d, the locking plate 204e is rotatably connected to the rotating frame 201, the L-shaped plate supports the locking plate 204e to prevent the locking plate 204e from rotating, the bottom of the locking plate 204e contacts the sliding block 203e, and the locking plate 204e prevents the sliding block 203e from sliding, and prevents the windproof cloth 203c from extending out to block the photovoltaic panel 203c during normal operation. 2, but when the rotating frame 201 rotates rapidly with the strong wind, the L-shaped top plate 204d will be affected by the centrifugal effect to overcome the thrust of the second elastic member 204c and move away from the locking plate 204e, so that the locking plate 204e can rotate, and the locking plate 204e will not be able to prevent the slider 203e from rotating, and the windward plate 203d will be pushed by the strong wind, which will drive the slider 203e to slide, and the windproof cloth 203c will extend out to block the surface of the photovoltaic panel 202 to prevent the photovoltaic panel 202 from being scratched by wind and sand. At the same time, since there are wind and sand protection components 203 on both sides of the bracket 107i, no matter which side the slider 203e slides on, it will eventually contact the slider 203e on the other end. Since the top of the slider 203e is magnetic, the slider 203e will be attracted together, so that the windproof cloth 203c is always wrapped around the surface of the photovoltaic panel 202 to enhance the protection effect.

[0042] In summary, during normal operation, the second elastic member 204c is in a compressed state, exerting a thrust on the L-shaped top plate 204d, and the L-shaped plate presses against the locking plate 204e to prevent the locking plate 204e from rotating. The locking plate 204e prevents the slider 203e from sliding, and prevents the windproof cloth 203c from extending out to block the working surface of the photovoltaic panel 202. When encountering strong wind extreme weather, no matter what wind direction is encountered, when the strong wind drives the photovoltaic assembly 200 to rotate rapidly, the L-shaped top plate 204d will be affected by the centrifugal effect to overcome the thrust of the second elastic member 204c and move away from the locking plate 204e, so The lock plate 204e can rotate, and the lock plate 204e will not be able to prevent the slider 203e from rotating. The windward plate 203d is pushed by the strong wind, which will drive the slider 203e to slide, and the windproof cloth 203c is extended to block the surface of the photovoltaic panel 202 to prevent the photovoltaic panel 202 from being scratched by wind and sand. At the same time, the slider 203e at the windward end of the rotating frame 201 slides and contacts the slider 203e at the other end. Due to the magnetic force, the two sliders 203e are adsorbed together, so that the windproof cloth 203c is always wrapped around the surface of the photovoltaic panel 202 to protect the surface of the photovoltaic panel 202 from being scratched by wind and sand.
