DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1-5As shown, the present invention provides a foldable photovoltaic bracket, including a bracket body 1, the bracket body 1 adopts a split design, the bracket body 1 includes a left bracket 2 and a right bracket 3, the left bracket 2 and the right bracket 3 are rotatably connected by a hinge 4, the setting of the hinge 4 facilitates the adjustment and rotation of the left bracket 2 and the right bracket 3, and facilitates the staff to disassemble and assemble the left bracket 2 and the right bracket 3, the left bracket 2 is consistent with the right bracket 3 in structure, the left bracket 2 includes a photovoltaic panel mounting frame 201, the lower part of the photovoltaic panel mounting frame 201 is movably connected with a support frame 202 and an adjustment frame 203, when the support frame 202 is unfolded, it is fixedly connected to the lower part of the photovoltaic panel mounting frame 201 by bolts, to ensure that the support frame 202 does not shake during the actual adjustment process. The adjusting frame 203 is installed on the right side of the supporting frame 202, and the supporting frame 202 and the adjusting frame 203 are rotatable. A supporting mechanism 5 is installed on the supporting frame 202, and the supporting mechanism 5 is movably connected to the supporting frame 202. Through the setting of the supporting mechanism 5, it is ensured that the supporting frame 202 can stably support the photovoltaic panel mounting frame 201, and the stability of the overall structure of the bracket body 1 is improved. A photovoltaic panel 204 is installed on the photovoltaic panel mounting frame 201, and a fixed limiting mechanism 6 is arranged between the left bracket 2 and the right bracket 3. Through the setting of the fixed limiting mechanism 6, it is ensured that the left bracket 2 and the right bracket 3 can stably maintain a fixed angle after splicing, which provides structural guarantee for sufficient lighting of the photovoltaic panel 204, and the fixed limiting mechanism 6 is movably connected to the bottom of the left bracket 2.

[0028] The specific configuration and functions of the photovoltaic panel mounting frame 201, the supporting mechanism 5 and the fixed limiting mechanism 6 are described in detail below;

[0029] like Figure 1-5 As shown, the photovoltaic panel mounting frame 201 is formed by a profile fixedly connected by fasteners. The profile is an aluminum profile. Through the design of the aluminum profile, the cost of the bracket is reduced, and it is convenient for the staff to install and maintain. The fastener is an angle code, which improves the overall flexibility of the photovoltaic panel mounting frame 201 and is convenient for the staff to change the area of ​​the photovoltaic panel mounting frame 201 according to the actual number of photovoltaic panels 204. The support frame 202 can be rotatably connected to the photovoltaic panel mounting frame 201. The support frame 202 is arranged in multiple groups at the bottom of the photovoltaic panel mounting frame 201. The adjusting frame 203 and the photovoltaic panel mounting frame 201 are rotatable, and the overall angle of the photovoltaic panel mounting frame 201 is adjusted by the setting of the adjusting frame 203. The support frame 202 and the adjusting frame 203 are connected by a rotating shaft 205, and the abutment between the rotating shaft 205 and the support frame 202 is fixed by a nut 206. The fixing work between the support frame 202 and the adjusting frame 203 is completed by the mutual cooperation of the rotating shaft 205 and the nut 206.

[0030] In this embodiment, both the support frame 202 and the adjustment frame 203 can be folded and recycled into the photovoltaic panel mounting frame 201. The left frame 2 and the right frame 3 can be folded into a whole. Compared with the design of conventional fixed photovoltaic brackets, the whole is foldable, which is convenient for disassembly and transportation, reduces the production and processing costs, and optimizes the spatial structure of existing photovoltaic brackets. The angle of the photovoltaic panel mounting frame 201 when supported is completed by the cooperation of the support frame 202 and the adjustment frame 203, and the lighting angle becomes adjustable, so that the photovoltaic panel mounting frame 201 can adapt to environments with different light intensities. The photovoltaic panel mounting frame 201 is made of aluminum profiles, which greatly reduces the cost of conventional construction. The connection of the photovoltaic panel mounting frame 201 is connected by angle codes, and the installation efficiency is greatly improved compared with the conventional welding connection method.

[0031] Example 2

[0032] like Figure 1-5 As shown, the support mechanism 5 includes a fixing plate 501, and the fixing plate 501 is sleeved on the support frame 202. The fixing plate 501 is symmetrically provided with anchor rods 502, and the anchor rods 502 and the fixing plate 501 are rotatable. The anchor rods 502 on both sides are inserted into the ground at the same time, so as to play a role in stabilizing the support frame 202 structure. A positioning plate 503 is installed on the support frame 202, and the positioning plate 503 is installed under the fixing plate 501. Through the setting of the positioning plate 503, the fixing plate 501 as a whole is guided and limited, so as to ensure that the fixing plate 501 will not continue to slide downward after contacting with the positioning plate 503 during actual working process. A baffle plate 504 is also installed on the fixing plate 501, and the baffle plate 504 is arranged on the left side of the anchor rod 502. The cross-section of the baffle 504 is arc-shaped. By arranging the baffle 504 on the left side of the anchor rod 502, it is ensured that the anchor rod 502 will not overturn, and can provide stable support for the support frame 202. The adjustment frame 203 is also provided with an adjustment hole 207. The setting of the adjustment hole 207 improves the angle adjustment range of the adjustment frame 203. The photovoltaic panel 204 is fixedly connected to the photovoltaic panel mounting frame 201 by screws. A protective plate 208 is also installed on the photovoltaic panel 204. The protective plate 208 is fixedly connected to the photovoltaic panel 204. The protective plate 208 is located on the left side of the screw to cover the screw that fastens the photovoltaic panel 204, so as to prevent the screw from being corroded, extend the service life of the screw, and ensure that the photovoltaic panel 204 is stably fixed on the photovoltaic panel mounting frame 201.

[0033] In this embodiment, by installing a supporting mechanism 5 on the supporting frame 202, the stability of the overall structure of the supporting frame 202 is improved, ensuring that the photovoltaic panel 204 can maintain a fixed angle during actual use and is not easily deformed, and by arranging anchor rods 502 on both sides of the fixing plate 501 and the bottom of the anchor rods 502 is designed to be conical, ensuring that when the supporting frame 202 is fixed to the ground, the anchor rods 502 on both sides are inserted into the ground to provide stable support for the supporting frame 202, and by setting the baffle plate 504, the space for the rotation and displacement of the anchor rods 502 is limited to prevent the anchor rods 502 from rotating to a position perpendicular to the supporting frame 202, and by pre-setting a positioning plate 503 on the supporting frame 202, the fixing plate 501 is positioned, and by setting the protective plate 208, the screws used to install the photovoltaic panel 204 are protected to prevent the screws from being corroded prematurely, thereby ensuring that the photovoltaic panel 204 is stably fixed on the photovoltaic panel mounting frame 201.

[0034] Example 3

[0035] like Figure 1-5 As shown, the fixed limiting mechanism 6 includes a limiting auxiliary shell 601, which is clamped under the photovoltaic panel mounting frame 201 and located between the left bracket 2 and the right bracket 3. Through the setting of the limiting auxiliary shell 601, after the left bracket 2 and the right bracket 3 are spliced, under the support of the limiting auxiliary shell 601, a reinforcing rod 602 is passed through the limiting auxiliary shell 601. Through the setting of the reinforcing rod 602, the overall strength of the limiting auxiliary shell 601 is enhanced to ensure that the limiting auxiliary shell 601 can stably support the left bracket 2 and the right bracket 3. The reinforcing rod 602 is supported by a limit spring 603. The limit spring 603 can protect the structure of the existing reinforcing rod 602, avoid stress concentration and damage the structure of the limit auxiliary shell 601, and extend the service life of the limit auxiliary shell 601. The photovoltaic panel mounting frame 201 is also provided with a handle 7, which is convenient for the staff to disassemble and transport the photovoltaic panel mounting frame 201. The angle between the left bracket 2 and the right bracket 3 is 135 degrees. The angle of 135 degrees ensures that the photovoltaic panel 204 has sufficient light.

[0036] In this embodiment, by setting up the fixed limiting mechanism 6, a fixed angle is maintained between the left bracket 2 and the right bracket 3, ensuring that the photovoltaic panel 204 on the photovoltaic panel mounting frame 201 is at a relatively efficient light conversion rate. The fixed limiting mechanism 6 is integrally clamped at the bottom of the photovoltaic panel mounting frame 201, which is convenient for the staff to install and maintain. The limiting auxiliary shell 601 is stabilized and reinforced by the cooperation of the reinforcing rod 602 and the limiting spring 603, thereby improving the stability of the overall structure of the foldable photovoltaic bracket and reducing maintenance costs.

[0037] The working principle of the present invention is as follows: the structures of the left bracket 2 and the right bracket 3 are designed to be consistent. When the bracket body 1 needs to be unfolded, the staff first adjusts the support frames 202 at the bottom of the left bracket 2 and the right bracket 3 from the retracted state to open them, and tightens the nuts 206 that fix the support frames 202 at the same time. The above completes the preliminary fixing work of the support frames 202, and then unfolds the adjustment frame 203. The adjustment frame 203 and the support frame 202 are rotatably connected through the rotating shaft 205. When the angle adjustment between the adjustment frame 203 and the support frame 202 is completed, the adjustment frame 203 and the support frame 202 are completed by tightening the nuts 206. The left bracket 2 and the right bracket 3 are connected by a hinge 4, so that the left bracket 2 and the right bracket 3 can rotate with each other. The adjustment frame 203 and the support frame 202 are distributed in multiple groups at the bottom of the left bracket 2. After the adjustment frame 203 and the support frame 202 complete the angle fixation, a stable support is formed between the left bracket 2 and the right bracket 3, and there will be no relative rotation between the left bracket 2 and the right bracket 3. Since the left bracket 2 and the right bracket 3 are symmetrically distributed, the support frame 202 and the adjustment frame 203 cooperate with each other to form a supporting force from bottom to top to stably support the left bracket 2 and the right bracket 3.

[0038] Then the staff manually clamps the position-limiting auxiliary shell 601 to the bottom of the photovoltaic panel mounting frame 201, and completes the reinforcement of the position-limiting auxiliary shell 601 structure through the reinforcement rod 602 in the position-limiting auxiliary shell 601.

[0039] Finally, the support mechanism 5 is installed on the support frame 202, and the staff puts the fixing plate 501 on the support frame 202. The positioning plate 503 is pre-installed on the support frame 202. When the fixing plate 501 abuts against the positioning plate 503, the support mechanism 5 is installed in place, and then the anchor rod 502 is manually opened. The bottom of the anchor rod 502 is designed to be conical, which is conducive to the rapid insertion of the anchor rod 502 into the ground to be installed. The anchor rods 502 are symmetrically arranged on both sides of the support frame 202 to increase the stability of the overall structure of the support frame 202. Through the setting of the support mechanism 5, the versatility of the overall structure of the foldable photovoltaic bracket is improved to meet the installation and use in different venues.

[0040] In summary, the support frame and the adjustment frame of the present invention can both be folded and recovered into the photovoltaic panel mounting frame, and the left frame and the right frame can both be folded into a whole. Compared with the design of the conventional fixed photovoltaic bracket, the whole is foldable, which is convenient for disassembly and transportation, and reduces the production and processing costs. The lighting angle becomes adjustable, so that the photovoltaic panel mounting frame can adapt to environments with different light intensities. The photovoltaic panel mounting frame is made of aluminum profiles, and the cost is greatly reduced compared with the conventional cost. The connection of the photovoltaic panel mounting frame is connected by angle codes, and the installation efficiency is greatly improved compared with the conventional welding connection method. The stability of the overall structure of the support frame is improved by installing a supporting mechanism on the support frame. , ensuring that the photovoltaic panel can maintain a fixed angle during actual use and is not easily deformed. The protective plate is set to protect the screws used to install the photovoltaic panel to avoid premature erosion of the screws, ensuring that the photovoltaic panel is stably fixed on the photovoltaic panel mounting frame. The fixed limit mechanism is set to maintain a fixed angle between the left bracket and the right bracket to ensure that the photovoltaic panel on the photovoltaic panel mounting frame is at a relatively efficient light conversion rate. The fixed limit mechanism is integrally clamped at the bottom of the photovoltaic panel mounting frame, which is convenient for staff to install and maintain. Compared with conventional photovoltaic brackets, the overall flexibility of the foldable photovoltaic bracket is greatly improved. It adopts a split splicing design, which is easy to disassemble and replace.
