Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component mounting structures, and in particular to a photovoltaic component mounting structure with an adjustment function and a use method thereof. Background Art

[0002] With the implementation of the dual carbon goals, rooftop distributed photovoltaic projects are in full swing. At present, the commonly used installation and fixing methods for photovoltaic modules are mainly back screw fixing and block pressing, and the installation and fixing methods are relatively simple. In addition, back screw fixing often makes it difficult to install the module because the hole position cannot be accurately controlled on the bracket, thus affecting the construction quality and speed; and the block fixing method requires the module to be tightened and fixed in sequence after it is placed in place, and the installation method is not flexible enough.

[0003] In addition, traditional installation methods may require additional customization or adjustment of brackets when facing photovoltaic panels of different sizes or models, which not only increases costs but also prolongs the installation process. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0005] The present invention adopts the following technical scheme: a photovoltaic component mounting structure with an adjustment function, comprising a base and a photovoltaic panel, a circular plate fixedly mounted on the surface of the base, a screw rod rotatably connected to the surface of the circular plate, a fixing plate fixedly mounted on the top end of the screw rod, a slide groove is provided inside the fixing plate, a sliding rod is slidably connected inside the slide groove, a screw sleeve is threadedly connected to the surface of the screw rod, a connecting rod is rotatably connected between the bottom surface of the sliding rod and the surface of the screw sleeve, a screw rod is fixedly mounted on the end surface of the sliding rod, a nut is threadedly connected to the surface of the screw rod, a fixing frame is fixedly mounted on the bottom surface of the photovoltaic panel, and a socket is provided on the surface of the fixing frame.

[0006] Preferably, a positioning block is fixedly mounted on the surface of the fixing plate, a positioning frame is fixedly mounted on the bottom surface of the photovoltaic panel, and the positioning block is inserted inside the positioning frame. Here, the combined use of the positioning block and the positioning frame enhances the installation accuracy and stability of the photovoltaic panel, and by ensuring that the photovoltaic panel is correctly and firmly installed in the predetermined position, installation errors and displacement during use can be effectively prevented, thereby improving overall reliability.

[0007] Preferably, a handle is fixedly mounted on the surface of the screw rod, and the handle is in a circular ring shape. Here, the use of a circular ring-shaped handle can facilitate personnel to rotate the screw rod, so that the screw sleeve can move up and down on the surface of the screw rod.

[0008] Preferably, the number of the slide bars is four groups, and the four groups of slide bars are evenly distributed around the fixing plate, and the positions of the screws correspond to the positions of the plug holes. Here, the screws on the slide bars can be stably assembled with the fixing frame on the photovoltaic panel, and at the same time, the stability of the supporting structure can be improved to avoid uneven force.

[0009] Preferably, bolts are inserted into the surface of the circular plate, screw holes are opened on the surface of the base, and the bolts are threadedly connected inside the screw holes. Here, the connection between the bolts and the screw holes provides additional fixing support, increases the stability and durability of the structure, is simple and economical, and is easy to install and maintain.

[0010] Preferably, a rotating block is fixedly mounted on the bottom surface of the circular plate, a rotating groove is provided on the surface of the base, and the circular plate rotates inside the rotating groove of the base through the rotating block. Here, the circular plate is allowed to rotate freely on the base, and the installation position of the photovoltaic panel can be easily adjusted.

[0011] Preferably, the screw holes are distributed in a circumference on the surface of the base, so that the bolts can be adapted to the screw holes at different positions to fix the adjusted position.

[0012] Preferably, the side of the photovoltaic panel is provided with a No. 1 protective frame and a No. 2 protective frame, a card plate is fixedly installed on the side of the No. 1 protective frame, a card slot is provided on the surface of the card plate, a plug block is fixedly installed on the side of the No. 2 protective frame, a groove is provided on the surface of the plug block, a card block is slidably connected inside the groove, a spring is fixedly connected between the card block and the groove, and the card block is engaged with the card slot. Here, the use of the No. 1 protective frame and the No. 2 protective frame can protect the side of the photovoltaic panel to avoid damage to the corners of the photovoltaic panel during the installation process. At the same time, the cooperation of the card block and the card slot can improve the convenience of connecting the No. 1 protective frame and the No. 2 protective frame.

[0013] Preferably, the number of the card blocks is two groups, and the two groups of card blocks are symmetrically distributed on both sides of the No. 2 protective frame. Here, the two groups of symmetrically distributed card blocks can make the connection between the No. 1 protective frame and the No. 2 protective frame more stable, avoiding unilateral falling off during use.

[0014] A method for using a photovoltaic assembly mounting structure with an adjustment function comprises the following steps: S1: To prevent the corners of the photovoltaic panels from being damaged during transportation, No. 1 and No. 2 protective frames are installed on the edges of the photovoltaic panels to provide additional physical protection for the photovoltaic panels and reduce damage caused by accidental collisions or scratches; S2: Install a card plate on the side of the No. 1 guard frame, and install an insert block on the side of the No. 2 guard frame. The insert block can be stably inserted into the card plate to ensure the structural stability of the guard frame; S3: A card block and a spring are arranged inside the insert block. The elastic force of the spring makes the card block tightly connected with the card slot on the card plate, which not only enhances the stability of the structure, but also facilitates the quick disassembly and assembly of the guard frame, thus improving the convenience of operation; S4: Place the photovoltaic panel on the fixing plate, and ensure that the positioning frame on the bottom of the photovoltaic panel is precisely matched with the positioning block on the fixing plate, so as to ensure that the photovoltaic panel can be accurately placed in the predetermined installation position and avoid deviation during operation; S5: Use the handle to rotate the lead screw to drive the screw sleeve to move on the lead screw, thereby driving the connecting rod and the sliding rod to slide inside the sliding groove of the fixed plate. When the end of the sliding rod is aligned with the inner side of the fixed frame of the photovoltaic panel, the screw at the end of the sliding rod passes through the jack of the photovoltaic panel fixed frame and is tightened with a nut, thereby achieving stable installation of the photovoltaic panel. S6: When adjusting the installation position of the photovoltaic panel, remove the bolts from the screw holes, and then rotate the circular plate to the appropriate position. Since the screw holes are distributed in a circle on the base, the best screw holes can be selected to re-fasten the bolts to ensure that the adjusted installation position is fixed.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, the screw rod and the screw sleeve cooperate so that the screw sleeve can move up and down, which can drive the connecting rod between the slide rod and the screw sleeve to rotate. The connecting rod drives the slide rod to slide in the slide groove, so that the screw rod at the end of the slide rod can be adapted to the jack of the fixed frame, thereby achieving the installation and fixation of the photovoltaic panel. At the same time, through the interaction between the slide groove in the fixed plate and the slide rod, the extension length of the slide rod can be adjusted according to the size of the photovoltaic panel, so that it can adapt to photovoltaic panels of different sizes, thereby improving the installation efficiency of the photovoltaic panel.

[0016] 2. In the present invention, the circular plate can rotate freely in the rotating groove of the base through the rotating block on the bottom surface, which provides greater flexibility for the installation position of the photovoltaic panel. The structure of the bolts and screw holes between the circular plate and the base provides additional stability and durability, ensuring that the entire installation structure can remain stable even in harsh environments. The circumferential distribution of the screw holes further enhances the adaptability of the structure, allowing the circular plate to be fixed at any necessary angle.

[0017] 3. In the present invention, the sides of the photovoltaic panels are additionally protected by the No. 1 and No. 2 protective frames, thereby improving the damage resistance of the corners of the photovoltaic panels. The No. 1 and No. 2 protective frames are combined with the card plates and plug blocks, and a fast and stable locking and unlocking mechanism is achieved through the internal card blocks and spring structures, thereby improving the overall convenience and safety of use. In addition, the symmetrical distribution design of the card blocks enhances the overall stability of the structure and avoids deflection or falling off during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A method for using a photovoltaic assembly mounting structure with an adjustment function comprises the following steps: S1: To prevent the corners of the photovoltaic panel 17 from being damaged during transportation, the first and second protective frames 22 are installed on the edges of the photovoltaic panel 17 to provide additional physical protection for the photovoltaic panel 17 and reduce damage caused by accidental collisions or scratches; S2: Install a card plate 23 on the side of the first protective frame 21, and install an insert block 25 on the side of the second protective frame 22. The insert block 25 can be stably inserted into the card plate 23 to ensure the structural stability of the protective frame; S3: A clamping block 27 and a spring 28 are arranged inside the inserting block 25. The elastic force of the spring 28 makes the clamping block 27 tightly connected with the clamping slot 24 on the clamping plate 23, which not only enhances the stability of the structure, but also facilitates the quick disassembly and assembly of the guard frame, thereby improving the convenience of operation; S4: placing the photovoltaic panel 17 on the fixing plate 9, ensuring that the positioning frame 20 on the bottom surface of the photovoltaic panel 17 is precisely matched with the positioning block 10 on the fixing plate 9, so as to ensure that the photovoltaic panel 17 can be precisely placed at the predetermined installation position to avoid deviation during operation; S5: Use the turning handle 8 to rotate the screw rod 7, drive the screw sleeve 11 to move on the screw rod 7, and then drive the connecting rod 12 and the sliding rod 13 to slide inside the sliding groove 16 of the fixing plate 9.

[0026] Working principle: When installing the photovoltaic panel 17, the photovoltaic panel 17 needs to be placed on the fixing plate 9 first.

By installing the card plate 23 on the side of the first protective frame 21 and the plug block 25 on the side of the second protective frame 22, the plug block 25 can be stably The fixed pin is inside the card plate 23. At the same time, a card block 27 and a spring 28 are arranged inside the plug block 25. Under the elastic force of the spring 28, the card block 27 is engaged with the card slot 24 of the card plate 23, so that it is convenient for personnel to disassemble and assemble the No. 1 guard frame 21 and the No. 2 guard frame 22, and the convenience of the No. 1 guard frame 21 and the No. 2 guard frame 22 is improved. After the photovoltaic panel 17 is placed, the positioning frame 20 on the bottom surface of the photovoltaic panel 17 is matched with the positioning block 10 on the fixing plate 9, so that the photovoltaic panel 17 It can be accurately placed in the installation position, and then the screw rod 7 is rotated by using the turning handle 8. When the screw rod 7 rotates, the screw sleeve 11 can move on the surface of the screw rod 7. During the movement of the screw sleeve 11, the connecting rod 12 is driven to rotate between the screw sleeve 11 and the sliding rod 13. At this time, the end of the connecting rod 12 away from the screw sleeve 11 drives the sliding rod 13 to slide inside the sliding groove 16 of the fixing plate 9. When the end of the sliding rod 13 fits with the inner side of the fixing frame 18 of the photovoltaic panel 17, the end of the sliding rod 13 The screw rod 14 passes through the insertion hole 19, and then the nut 15 is tightened on the surface of the screw rod 14, so that the photovoltaic panel 17 can be stably installed on the fixing plate 9. The installation position of the photovoltaic panel 17 needs to be adjusted. At this time, the bolt 4 is removed from the screw hole 3, and then the circular plate 5 is rotated and adjusted to a suitable position.
