As a key component supporting the photovoltaic panels in a PV power generation system, the rationality of its structural design and its functionality directly affect the installation efficiency, power generation efficiency, and overall stability of the PV power generation system.

[0003] Existing photovoltaic (PV) mounting systems have several shortcomings in practical use. Firstly, most PV mounting systems have fixed structures, making it difficult to achieve folding and extension functions. They occupy a significant amount of space during installation and transportation, increasing transportation costs and installation difficulty. Furthermore, they do not effectively save space when not in use, hindering flexible application. Secondly, traditional PV mounting systems offer limited methods for fixing PV panels, making it difficult to adapt to the installation needs of PV panels of different sizes. The lack of effective adjustment mechanisms restricts their application range. In addition, the support structures of existing PV mounting systems often lack angle rotation and flexible extension / retraction capabilities, making it difficult to quickly adjust to different terrains and lighting conditions. This fails to ensure that PV panels receive optimal sunlight, thus affecting PV power generation efficiency. Therefore, there is an urgent need for a novel and multifunctional PV mounting system to solve the aforementioned problems in existing technologies. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 7 As shown, this utility model provides a foldable, extendable photovoltaic bracket, comprising: The fixing frame 1 has a sliding groove 2 inside; A folding mechanism is provided on the outer surface of the fixed frame 1; The folding mechanism includes a fixed block 4, a lever 5 is slidably connected inside the fixed block 4, a plug rod 7 is fixedly installed on the outer surface of the lever 5, a folding frame 8 is hinged to the outer surface of the fixed frame 1, the bottom end of the folding frame 8 is attached to the top end of the fixed frame 1, and a plug hole 10 is fixedly installed on the top end of the folding frame 8.

[0019] Since the folding frame 8 is hinged to the fixed frame 1, the folding frame 8 can rotate around the hinge point with the fixed frame 1 as the axis. During this process, the photovoltaic bracket will be in the unfolded state. When the photovoltaic bracket is in the unfolded state, the inside of the fixed block 4 will be aligned with the inside of the socket 10. At this time, if the plug rod 7 is inserted into the socket 10, it will fix the unfolded state of the folding frame 8.

[0020] The outer surface of the paddle 5 is fixedly mounted with a first spring 6, and the end of the first spring 6 away from the paddle 5 is fixedly connected to the inside of the fixing block 4.

[0021] When the operator moves the lever 5, the lever 5 will drive the insert rod 7 to move left and right along the inside of the fixed block 4. During this process, the first spring 6 will be compressed. Due to the design of the first spring 6, it will have a good reset effect on the movement of the lever 5 and the insert rod 7.

[0022] The top of the fixed frame 1 is fixedly installed with a first support block 3, the outer surface of the first support block 3 is in contact with the bottom of the folding frame 8, and the inside of the top of the fixed frame 1 is in contact with a second support block 9, the top of the second support block 9 is fixedly connected to the bottom of the folding frame 8.

[0023] Due to the design of the first support block 3 and the second support block 9, a flat surface is provided for the photovoltaic panel, allowing it to be placed stably.

[0024] The slide 2 has a movable rod 11 slidably connected inside, and a clamping block 12 is fixedly installed at one end of the movable rod 11 located outside the slide 2.

[0025] Since the movable rod 11 is slidably connected to the inside of the slide 2, when the operator pulls the clamp 12, the movable rod 11 will move along the inside of the slide 2.

[0026] The slide groove 2 is movably fitted with a second spring 13. One end of the second spring 13 is fixedly connected to the inside of the slide groove 2, and the other end of the second spring 13 is fixedly connected to the movable rod 11. The inside of the second spring 13 is movably fitted with the outer surface of the movable rod 11.

[0027] When the movable rod 11 moves along the inside of the slide groove 2, it will compress the second spring 13. Due to the elastic force of the second spring 13, it will have a good reset effect on the overall movement of the movable rod 11. When the clamping block 12 is reset under the drive of the movable rod 11, it will be able to clamp and fix the photovoltaic panel.

[0028] The bottom end of the fixed frame 1 is fixedly installed with a hinge block 14, and a rotating block 15 is hinged inside the hinge block 14.

[0029] Since the rotating block 15 is hinged to the hinge block 14, the rotating block 15 can rotate around the hinge point with the hinge block 14 as the axis.

[0030] The front end of the rotating block 15 is fixedly installed with a telescopic rod 16, and a support column 17 is slidably connected to the outer surface of the telescopic rod 16.

[0031] When the rotating block 15 rotates, it will drive the support column 17 to rotate through the telescopic rod 16. Since the telescopic rod 16 is slidably connected to the inside of the support column 17, the telescopic rod 16 can extend and retract along the inside of the support column 17.

[0032] The support column 17 has a base 18 fixedly installed at its front end, and the base 18 has a bolt 19 threaded into its internal thread.

[0033] The design of the base 18 and bolt 19 allows the bracket to be easily installed on the ground.

[0034] Among them, threaded sleeves 20 are fixedly sleeved inside the outer surface of the hinge block 14 and the support column 17, and screws 21 are threaded inside the threaded sleeves 20. A screwing block 22 is fixedly installed on the right end of the screw 21.

[0035] When the operator turns the turning block 22, it will drive the screw 21 to rotate. Since the screw 21 is threadedly connected to the inside of the threaded sleeve 20, when the screw 21 rotates, it will move along the inside of the threaded sleeve 20. When the screw 21 comes into contact with the rotating block 15 or the telescopic rod 16 during the movement, it will squeeze and push them to achieve the effect of locking their movement.

[0036] Working principle and usage process of this utility model: When the operator needs to install the photovoltaic bracket, firstly, the operator places the base 18 on the cement pile at the installation location. Then, the operator screws the bolts 19 into the cement pile through the inside of the base 18 to fix the photovoltaic bracket to the ground. Next, the operator bends the entire bracket 1, causing it to rotate around the hinge point of the hinge block 14 and the rotating block 15. When the bracket 1 rotates to the appropriate angle, the operator stops bending it. Then, the operator tightens the screw block 22 on the hinge block 14. This tightening block 22 will drive the screw 21 to rotate. Since the outer surface of the screw 21 is engaged with the internal thread of the threaded sleeve 20, when the screw 21… During rotation, the screw will move to the left along the inside of the threaded sleeve 20. Then, the left end of the screw 21 will contact the outer surface of the rotating block 15 during the movement and squeeze and push the rotating block 15. At this time, the screw 21 will play a good blocking role against the rotation of the hinge block 14 as a whole, so as to achieve the effect of fixing the entire frame 1. Then, the operator pulls the telescopic rod 16, so that the telescopic rod 16 moves upward along the inside of the support column 17. During this process, the overall height of the frame 1 will be raised. When the frame 1 is raised to a suitable height, the operator will turn the screwing block 22 on the support column 17. Then, the screw 21 will squeeze and push the telescopic rod 16 to achieve the effect of fixing the entire telescopic rod 16. When the operator needs to install the photovoltaic panel, the operator pulls the two sets of clamping blocks 12. At this time, the two sets of clamping blocks 12 will drive the two sets of movable rods 11 to move in opposite directions. During this process, the two sets of second springs 13 will be compressed. Then the operator places the photovoltaic panel on the two folding frames 8. After the photovoltaic panel is placed, the operator releases the clamping blocks 12. Due to the elastic force of the second springs 13, the two sets of clamping blocks 12 will reset. Then the two sets of clamping blocks 12 will clamp and fix the photovoltaic panel in motion. When an operator needs to fix a large photovoltaic panel, firstly, the operator pulls the lever 5, causing the lever 5 to move the insertion rod 7 along the inside of the fixing block 4, so that the insertion rod 7 retracts into the inside of the fixing block 4. During this process, the first spring 6 is compressed. Then, the operator drives the two folding frames 8 to rotate around the hinge point with the fixing frame 1. During this process, the two folding frames 8 will be in an unfolded state. When the two folding frames 8 are fully unfolded, the inside of the insertion hole 10 will be aligned with the inside of the fixing block 4. At this time, the operator releases the lever 5. Due to the elastic force of the first spring 6, the first spring 6 will then retract. A spring 6 will drive the insert rod 7 to reset via the lever 5 and insert it into the socket 10. At this time, the insert rod 7 will lock the folding frame 8 through the socket 10. Then, the operator pulls the two sets of clamps 12 to make the two sets of clamps 12 move in opposite directions. Then, the operator places the large-size photovoltaic panel on the top of the first support block 3 and the second support block 9. After the photovoltaic panel is placed, the operator releases the clamps 12 to complete the fixation of the large-size photovoltaic panel. Due to the design of the first support block 3 and the second support block 9, a flat placement surface can be provided for the photovoltaic panel, which provides good support for the photovoltaic panel.
