[0041] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0042] See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a photovoltaic panel installation structure of a photovoltaic energy storage system, comprising a main support frame 100, a plurality of auxiliary support frames 200 detachably connected to the main support frame 100, and photovoltaic panel installation frames 300 distributed on the auxiliary support frames 200 in a rectangular array, mutually perpendicular channels L1 and channels L2 are respectively formed between adjacent photovoltaic panel installation frames 300, and a group of fixing structures 500 for installing photovoltaic panels 400 are arranged at each intersection P of the channel L1 and the channel L2;

[0043] See also Figure 7 and Figure 8 The fixing structure 500 includes a plate body 510 mounted on the upper end surface of the photovoltaic panel mounting frame 300, and a cross-shaped positioning block 520 is integrally connected to the side of the plate body 510 facing the main support frame 100, and the cross-shaped positioning block 520 is adapted to the channel L1 and the channel L2;

[0044] The plate body 510 is provided with four groups of mounting grooves 511 symmetrically on one side away from the main support frame 100. The mounting grooves 511 are provided with supporting members 530 for supporting the photovoltaic panels 400. The side walls of the mounting grooves 511 are provided with wrapping members 570 for wrapping the edges of the photovoltaic panels 400.

[0045] A threaded rod 550 is threadedly connected at the center of the plate body 510, and a pressure plate 540 for pressing and fixing the photovoltaic panel 400 is movably sleeved on the rod body of the threaded rod 550; when the threaded rod 550 is rotated downward, the pressure plate 540 can be driven to press the photovoltaic panel 400, and at the same time, the wrapping member 570 can be driven to wrap the edge of the photovoltaic panel 400.

[0046] Specifically, see Figure 3 , Figure 4 , Figure 5 and Figure 6 , insert the cross-shaped positioning block 520 in the fixing structure 500 into the channel L1 and the channel L2 at the corresponding intersection P until the plate body 510 fits with the upper end surface of the surrounding photovoltaic panel mounting frame 300;

[0047] In the initial state, the pressing plate 540 is staggered with the corresponding installation groove 511, so as to facilitate the installation of the photovoltaic panel 400. The photovoltaic panel 400 is placed directly above the photovoltaic panel installation frame 300, so that the four corners of the photovoltaic panel 400 are respectively embedded in the corresponding installation grooves 511 of the corresponding fixing structure 500, and the lower end surfaces of the four corners of the photovoltaic panel 400 are all supported on the corresponding supporting members 530;

[0048] After the photovoltaic panel 400 is put in place, rotate the pressure plate 540 to the top of the installation groove 511, and rotate the threaded rod 550 downward to drive the pressure plate 540 downward until the pressure plate 540 presses the photovoltaic panel 400 against the supporting member 530 to achieve the installation and fixation of the photovoltaic panel 400; at the same time, the downwardly rotated threaded rod 550 can push the wrapping member 570 on the side wall of the installation groove 511 to extend horizontally, thereby wrapping the edge of the photovoltaic panel 400 to achieve edge protection for the photovoltaic panel 400.

[0049] See also Figure 8 The supporting member 530 includes an adjusting ball 531 movably embedded in the bottom of the mounting groove 511 , and a tray 532 is fixedly connected to the adjusting ball 531 , and the tray 532 is located at the center of the mounting groove 511 ;

[0050] Specifically, the photovoltaic panel 400 is placed on the tray 532. Since the adjustment ball 531 can be rotated and adjusted to any angle relative to the mounting groove 511, when the photovoltaic panel 400 is bent and deformed by a large wind impact, the tray 532 can adaptively deflect following the deformation amplitude of the photovoltaic panel 400, so that the tray 532 can always fit completely with the photovoltaic panel 400, effectively reducing the concentrated stress at the edge of the photovoltaic panel 400, and preventing the photovoltaic panel 400 from being broken due to a large squeezing force between the photovoltaic panel 400 and the tray 532 due to excessive deformation.

[0051] See also Figure 8 , Fig. 9 , Fig.10 and Fig.11 The pressure plate 540 includes a collar 541 movably sleeved on the threaded rod 550, and four groups of pressure rods 542 are circumferentially arranged on the collar 541. A stepped groove 543 is provided on the end surface of the pressure rod 542 facing the mounting groove 511, and a U-shaped elastic pressure piece 544 is movably embedded in the stepped groove 543. Sliding blocks 545 adapted to the stepped groove 543 are installed on both sides of the U-shaped elastic pressure piece 544, and a first spring 546 is provided between the inner wall of the stepped groove 543 and the corresponding sliding block 545; the plate body 510 is provided with avoidance grooves 512 adapted to each pressure rod 542, and the avoidance grooves 512 are located between adjacent mounting grooves 511;

[0052] Specifically, in the initial state, the collar 541 is rotated so that each group of pressure rods 542 are respectively located in the corresponding avoidance groove 512, so that the pressure rods 542 and the installation groove 511 are staggered in the vertical direction, which is convenient for placing the photovoltaic panel 400 into the installation groove 511. At this time, the U-shaped elastic pressure piece 544 is retracted into the stepped groove 543 under the restriction of the avoidance groove 512;

[0053] When the photovoltaic panel 400 is placed in place, the collar 541 is rotated again to make each group of pressure rods 542 rotate just above the corresponding installation groove 511. At this time, the U-shaped elastic pressure piece 544 is no longer restricted by the avoidance groove 512, so that under the elastic force of the first spring 546, the sliding blocks 545 on both sides are squeezed toward the middle at the same time, thereby driving the U-shaped elastic pressure piece 544 to deform, so that the U-shaped elastic pressure piece 544 pops up downward;

[0054] When the threaded rod 550 is screwed down, the pressure rod 542 is pressed down, so that the U-shaped elastic pressure piece 544 contacts the upper end surface of the photovoltaic panel 400, and the U-shaped elastic pressure piece 544 is pressed and fixed to the photovoltaic panel 400 by the dual cooperation of the threaded rod 550 and the first spring 546.

[0055] It should be noted that since the U-shaped elastic pressure piece 544 has elastic deformation properties, when the photovoltaic panel 400 is deformed by wind impact, the U-shaped elastic pressure piece 544 can also adaptively deform following the deformation amplitude of the photovoltaic panel 400, thereby always being able to provide a stable fixing effect for the photovoltaic panel 400, while allowing the photovoltaic panel 400 to have a certain deformation range, thereby avoiding the local stress of the photovoltaic panel 400 from not being released and causing breakage.

[0056] For further information, see Fig.10 and Fig.11 In order to prevent the entire pressing plate 540 from deflecting during the process of pressing the photovoltaic panel 400 and causing the pressure on the photovoltaic panel 400 to shift, it also includes a locking ring 590 and a pressing spring 580. The locking ring 590 is sleeved on the threaded rod 550 and is located above the collar 541. The collar 541 and the plate body 510 are both provided with a plurality of positioning holes 547. The locking ring 590 is circumferentially provided with a plurality of pins 591 adapted to the positioning holes 547. The pressing spring 580 is sleeved on the threaded rod 550. The lower end of the pressing spring 580 abuts against the locking ring 590, and the upper end abuts against the upper end of the threaded rod 550.

[0057] When the pressure rod 542 rotates into the avoidance groove 512 or rotates to just above the installation groove 511, the ring 541 is aligned with the corresponding positioning hole 547 on the plate body 510, and the pin 591 on the locking ring 590 is inserted through the two aligned positioning holes 547, so that the ring 541 and the plate body 510 can be circumferentially locked to prevent the pressure rod 542 from rotating randomly and affecting the posture of the pressure rod 542. At the same time, the clamping spring 580 can ensure that the locking ring 590 is always in contact with the ring 541, to prevent the pin 591 from coming out of the positioning hole 547 and causing locking failure.

[0058] See also Fig.10 and Fig.11 The wrapping member 570 includes an annular airbag 571 embedded in the plate body 510 and four groups of strip airbags 572 circumferentially distributed on the periphery of the annular airbag 571. The annular airbag 571 is sleeved on the outside of the threaded rod 550. A pressure plate 551 for axially squeezing the annular airbag 571 is fixedly installed on the threaded rod 550.

[0059] Each strip-shaped airbag 572 is connected to the annular airbag 571. The strip-shaped airbag 572 is located between adjacent mounting grooves 511. The side wall of the mounting groove 511 is provided with a receiving groove 513 for accommodating the strip-shaped airbag 572.

[0060] Specifically, when the photovoltaic panel 400 is put in place, the threaded rod 550 is screwed down to drive the pressure plate 551 to move downward synchronously, so that the annular airbag 571 is squeezed downward by the pressure plate 551. The air in the annular airbag 571 enters into each strip airbag 572 under the squeezing action of the pressure plate 551, so that each strip airbag 572 expands and extends out from the storage groove 513, so as to achieve wrapping protection for the edge of the photovoltaic panel 400, and prevent the photovoltaic panel 400 from being scratched or even broken by rubbing against the side wall of the installation groove 511 when the photovoltaic panel 400 is deformed.

[0061] For further information, see Fig.12 and Fig.13 , for the connection and fixation between the fixing structure 500 as a whole and the photovoltaic panel mounting frame 300, a fixing member 560 is also included, and the fixing member 560 is provided with four groups and is circumferentially distributed on the cross-shaped positioning block 520, and the fixing member 560 includes a vertically distributed transverse slide rail 561 and a radial slide rail 562, and the transverse slide rail 561 is symmetrically slidably provided with transverse sliders 563 on both sides, and the radial slide rail 562 is slidably provided with a radial slider 565, and the radial slider 565 and the transverse sliders 563 on both sides are hinged with a connecting rod 566, and a second spring 567 is provided between the radial slider 565 and the transverse slide rail 561;

[0062] See also Fig.10The lower end of the threaded rod 550 is rotatably sleeved with a sleeve 568, and the sleeve 568 is circumferentially provided with four groups of wedge-shaped push blocks 569, and the wedge-shaped push blocks 569 are adapted to the corresponding radial sliders 565, and the cross-shaped positioning block 520 is provided with a telescopic groove 514 for accommodating the corresponding wedge-shaped push blocks 569;

[0063] A telescopic pin 564 is installed on the transverse slider 563, and a hollow groove 210 adapted to the telescopic pin 564 is opened in the auxiliary support frame 200;

[0064] Specifically, the cross-shaped positioning block 520 is inserted into the channel L1 and the channel L2 at the point P until the plate body 510 fits with the photovoltaic panel mounting frame 300;

[0065] When the threaded rod 550 is screwed down to drive the pressure plate 540 to press the photovoltaic panel 400 and drive the wrapping member 570 to cover the edge of the photovoltaic panel 400, the threaded rod 550 drives the sleeve 568 to move downward synchronously, so that each wedge-shaped push block 569 slides downward along the corresponding telescopic groove 514, and the wedge-shaped push block 569 is used to squeeze the corresponding radial slider 565 downward, so that the corresponding radial slider 565 slides along the radial slide rail 562 toward the side of the transverse slide rail 561, and under the transmission of the connecting rod 566, the transverse sliders 563 on both sides are driven to slide away from each other along the transverse slide rail 561, so that the telescopic pins 564 on both sides are synchronously extended horizontally and inserted into the corresponding hollow groove 210. At this time, the telescopic pin 564 just abuts against the top wall of the hollow groove 210 close to the photovoltaic panel mounting frame 300, so as to realize the fixation between the cross-shaped positioning block 520 and the auxiliary support frame 200, and prevent the entire fixed structure 500 from falling off.

[0066] It is worth noting that by rotating the threaded rod 550, the pressure plate 540, the wrapping member 570 and the fixing member 560 can be driven to move at the same time, and only one driving action is required to complete the triggering effect of multiple functional blocks, thereby enabling the photovoltaic panel 400 to be quickly disassembled and assembled, effectively improving the installation efficiency.

[0067] See also Fig.14 and Fig.15 , with regard to the connection method between the main support frame 100, the auxiliary support frame 200 and the photovoltaic panel mounting frame 300, the photovoltaic panel mounting frame 300 is pasted on the auxiliary support frame 200, the main support frame 100 is provided with a slide bar 110, and the auxiliary support frame 200 is provided with a slide groove adapted to the slide bar 110; a T-shaped reinforcement block 600 is provided between adjacent auxiliary support frames 200, the bottom of the T-shaped reinforcement block 600 is abutted against the main support frame 100, and the two ends of the T-shaped reinforcement block 600 are respectively abutted against the corresponding auxiliary support frame 200, and the T-shaped reinforcement block 600 is detachably connected to the main support frame 100 by fastening bolts 700;

[0068] Specifically, align the slide groove on the sub-support frame 200 with the corresponding slide bar 110 on the main support frame 100, and slide the slide bar 110 into the slide groove to connect the sub-support frame 200 to the main support frame 100, and then press the T-shaped reinforcement block 600 on the sub-support frame 200 and the main support frame 100, and use the fastening bolts 700 to connect and fix the T-shaped reinforcement block 600 to the main support frame 100, thereby effectively preventing the sub-support frame 200 from slipping relative to the slide bar 110; when the sub-support frame 200 is installed, every four sub-support frames 200 are enclosed to form a rectangular unit, and each group of rectangular units is installed with a group of photovoltaic panel mounting frames 300, and the photovoltaic panel mounting frames 300 are bonded to the four sub-support frames 200 of the rectangular unit using structural adhesive.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
