Description

Technical Field

[0001] The present invention relates to the field of photovoltaic panel assembly, and more specifically, to a photovoltaic panel parallel splicing and combining device. Background Art

[0002] The installation of photovoltaic panels requires fixing brackets on the site according to the actual site conditions, and then fixing the photovoltaic panels above the brackets to complete the installation and fixation of the photovoltaic panels. During the actual installation process, the support frame needs to be set with a support frame that can be telescopically adjusted in height according to the light irradiation position of the installation location to improve the use effect of the photovoltaic panels after installation.

[0003] During the installation process of the photovoltaic panels and the support frame, it is necessary to gradually combine the single photovoltaic panels with the support manually or through machinery. Facing the fixation of a large area of photovoltaic panels, it is difficult to directly lay and install all the photovoltaic panels at one time. Moreover, after the single-installed photovoltaic panels are installed, there is no connection between the panels, which is likely to result in insufficient strength.

[0004] Therefore, we make improvements on this and propose a photovoltaic panel parallel splicing and combining device. Summary of the Invention

One end of the support transmission plate 5 is fixed on the inner wall of the mother-child combination rack 3. A hydraulic transmission cylinder 6 slides in the middle of the support transmission plate 5. The upper and lower output ends of the hydraulic transmission cylinder 6 are universally hinged to the outer wall of the plate clamping plate 4.

The unfolding of the photovoltaic panel 2 drives the rotation of the L-shaped daughter rack 31 and the L-shaped mother rack 32. The rotation of the L-shaped daughter rack 31 and the L-shaped mother rack 32 drives the stretching of the folding air pressure group 7. The folding air pressure group 7 absorbs external air under the tensile force to form a buffer.

[0026] A photovoltaic panel parallel splicing and combining device provided by the present invention can splice and connect two groups of photovoltaic panels 2 in series and parallel through the setting of the mother-daughter combination rack 3, so that multiple groups of photovoltaic panels 2 can be folded and stored.

[0038] Embodiment 2 Further optimize the photovoltaic panel parallel splicing and combining device provided in Embodiment 1. Specifically, as Figures 1 - 12 , the folding air pressure group 7 includes embedded rotating grooves 71 opened on both sides of the L - shaped sub - frame 31 and the L - shaped mother - frame 32. Inside the embedded rotating grooves 71, symmetric push - rod hinge seats 711 are hinged on the inner sides of the L - shaped sub - frame 31 and the L - shaped mother - frame 32.

One side of the air chamber 721 close to the outer walls of the L - shaped sub - frame 31 and the L - shaped mother - frame 32 is provided with an air - vent net opening 725.

[0040] There is a folding air pressure group 7 between the mother - son combination frames 3. During the unfolding process of the mother - son combination frames 3, through the pneumatic pressure of the pneumatic push - rods 712, the pressure exerted on the mother - son combination frames 3 when the photovoltaic panel 2 unfolds can be reduced, enabling the mother - son combination frames 3 to unfold slowly during unfolding, thus ensuring the stability of the unfolding of the photovoltaic panel 2. At the same time, one end of the pneumatic push - rod 712 is connected with a valve body for adjusting the internal pressure of the pneumatic push - rod 712, enabling the pneumatic push - rod 712 to have the function of freely regulating pressure.

[0041] The usage process of the photovoltaic panel parallel splicing and combining device provided by the present invention is as follows: First, the mother - son combination rack 3 and the photovoltaic panel 2 are assembled and installed. When installing the mother - son combination rack 3 and the photovoltaic panel 2, directly snap the mother - son combination rack 3 onto the outside of the protective shell 21 on the outer walls of two groups of photovoltaic panels 2. During the snapping process, as the photovoltaic panel 2 enters the space inside the mother - son combination rack 3, the protective shell 21 on the outer wall of the photovoltaic panel 2 will abut against the plate - body contact block 565.

[0042] At this time, the plate - body contact block 565 will receive a thrust and slide into the transmission seal groove 54. When the plate - body contact block 565 is completely squeezed into the transmission seal groove 54, the driven transmission bar 56 connected to the plate - body contact block 565 will drive the one - way flow port 561 to slide towards the positions of the communication port 542 and the liquid outlet groove 541. As the communication port 542, the liquid outlet groove 541 and the one - way flow port 561 are connected, the liquid in the hydraulic storage area will be pushed by the high - pressure spring 556, causing the liquid to pass through the liquid outlet groove 541 to push the valve plate 562 to rotate, and the liquid to flow through the communication port 542 towards the liquid transmission pipe 65. The liquid flows through the liquid transmission pipe 65 into the hydraulic chamber 61.

[0043] Since the hydraulic chamber 61 is divided into upper and lower parts, the liquid will simultaneously drive the upper and lower groups of output push rods 63 to slide outwards. As the output push rods 63 slide, the second universal balls 64 at the output ends of the connected output push rods 63 will push the two groups of plate - body clamping plates 4 to move.

[0044] Since the middle part of the plate - body clamping plate 4 is hinged by the universal hinge balls 42, and the universal hinge balls 42 are fixed inside the embedded groove 311 through the fixing rods 43, when one end of the plate - body clamping plate 4 receives a thrust, the other end will follow the lever principle to clamp and fix the protective shell 21 inserted in the middle of it.

[0045] It should be noted that: since the plate - body clamping plate 4 is hinged and fixed to the embedded groove 311 through two groups of universal hinge balls 42 and fixing rods 43, and the second universal ball 64 is hinged at the center of one side of the two groups of universal hinge balls 42, the plate - body clamping plate 4 has a stable lever transmission effect.

[0046] It should be noted that: the high - pressure spring 556 pushes the liquid to flow through the elastic - force pushing block 554, converting the liquid flow in the hydraulic transmission cylinder 6 into a driving force, enabling the plate - body clamping plate 4 to have sufficient driving strength (specifically, the principle of a jack can be referred to). After the plate - body clamping plate 4 clamps the protective shell 21, when the photovoltaic panel 2 is forced to push the protective shell 21 to push the plate - body clamping plate 4, since the valve plate 562 in the one - way flow port 561 is a one - way valve, the liquid in the hydraulic transmission cylinder 6 cannot flow back reversely into the hydraulic storage area, so it can ensure that the plate - body clamping plate 4 always has sufficient clamping force.

[0047] When the driving force of the liquid flow pressure inside the hydraulic storage area 543 is insufficiently pushed by the high-pressure spring 556, it is possible to rotate by turning the manual clamping rod 55. The rotation of the manual clamping rod 55 will drive the threaded rod 552 screwed inside it to move to one side. As the threaded rod 552 moves, the threaded rod 552 will push the active pushing block 553 to move, and the active moving block will push the elastic pushing block 554 to move, realizing the extrusion of the liquid inside the hydraulic storage area, thereby increasing the clamping strength of the plate body clamping plate 4 on the protective shell 21.

[0048] When it is necessary to remove the parent-child combination rack 3 and the photovoltaic panel 2, the driving hinge rod 563 and the active driving block 564 connected by the hinge of the driving valve plate 562 can be rotated, and the active valve plate 562 is rotated to open the valve plate 562, so that the hydraulic transmission cylinder 6 and the hydraulic storage area can be connected. At this time, the plate body clamping plate 4 is subjected to a thrust force, and the liquid inside the hydraulic transmission cylinder 6 can be compressed and enter the inside of the hydraulic storage area 543, completing the opening of the plate body clamping plate 4, and then the photovoltaic panel 2 can be taken out.

[0049] It should be noted that when installing the parent-child combination rack 3, the two sides of a single photovoltaic panel 2 are connected to the sub-rack and the parent-rack of the parent-child combination rack 3, and the other photovoltaic panel 2 is connected to the sub-rack and the parent-rack of another set of parent-child combination racks 3 to realize the connection between the photovoltaic panels 2. At the same time, because the parent-child combination rack 3 has a rotation function, the connected photovoltaic panels 2 can be folded.

[0050] Moreover, the surface of the plate body clamping plate 4 is provided with rubber, which can ensure the safety of the stacked photovoltaic panels 2 when the photovoltaic panels 2 are folded and placed after being combined.

[0051] When the photovoltaic panels 2 are combined, the support frame is fixed at the position where the photovoltaic panels 2 need to be installed. When installing, the support rod 11 needs to be fixed in a straight line, and then the double slide rod is fixed above the support rod 11. When installing two groups of support rods 11, according to the size of the photovoltaic panels 2, the distance between the two groups of double slide rods should match the size of the photovoltaic panels 2.

[0052] When the length of the combined photovoltaic panels 2 through the parent-child combination rack 3 is sufficient, all the combined photovoltaic panels 2 are lifted by lifting equipment, and the hinge plates 312 and hinge plates 313 on the outer wall of the parent-child combination rack 3 are placed inside the double slide frame 12. Then, by pulling the edge photovoltaic panels 2 at both ends of the folded photovoltaic panels 2, the folded photovoltaic panels 2 can be gradually unfolded.

[0053] During the unfolding process of the photovoltaic panels 2, since the parent-child combination rack 3 is limited and slides inside the double slide frame 12 through the hinge plates 312 and hinge plates 313, it can ensure the sliding stability of the unfolding of the photovoltaic panels 2 without detaching from the plate body mounting rack 1.

[0054] During the unfolding process of the photovoltaic panel 2, the folding air pressure group 7 arranged between the mother-child combination frames 3 will be pulled and opened. During the opening process, the two pneumatic push rods 712 will stretch outwards, and the double-acting piston rod 713 located inside the pneumatic push rod 712 will gradually disengage from the pneumatic push rod 712.

[0055] It should be noted that: Since the pneumatic push rod 712 is hermetically connected through the double-acting piston rod 713, when the photovoltaic panel 2 unfolds, there is a negative pressure when the double-acting piston rod 713 disengages from the pneumatic push rod 712. This negative pressure can absorb the pressure exerted when the photovoltaic panel 2 unfolds, enabling the photovoltaic panel 2 to slowly unfold and descend, thereby ensuring the safety of the photovoltaic panel 2 during the unfolding process.

[0056] When installing the mother-child combination frame 3 for photovoltaic panels 2 of different sizes and weights, it is necessary to adjust the negative pressure between the pneumatic push rod 712 and the double-acting piston rod 713 inside the folding air pressure group 7 according to the weight of the photovoltaic panel 2, so that the negative pressure generated by the sliding between the pneumatic push rod 712 and the double-acting piston rod 713 is proportional to the photovoltaic panel 2, thereby enabling the mother-child combination frame 3 to be applicable to the unfolding of any type of photovoltaic panel 2.

[0057] When adjusting the negative pressure between the pneumatic push rod 712 and the double-acting piston rod 713 inside the folding air pressure group 7, the spherical drive block 724 can be rotated. The spherical drive block 724 will drive the valve ball 723 to rotate. The rotation of the valve ball 723 will gradually close and reduce the position of the through hole connecting the middle of the valve ball 723 and the chamber connecting pipe 722, thereby completing the adjustment of the negative pressure between the pneumatic push rod 712 and the air chamber 721.

[0058] When the double-acting piston rod 713 inside the pneumatic push rod 712 extends during the unfolding of the photovoltaic panel 2 to drive it, the double-acting piston rod 713 will extract the air inside the pneumatic push rod 712. The pneumatic push rod 712 will then absorb the air inside the air chamber 721 through the connecting air pipe 714. Since the air chamber 721 and the connecting air pipe 714 are connected by a ball valve, the rotation speed of the photovoltaic panel 2 during unfolding can be freely adjusted.

[0059] It should be noted that: The distance between the two double-sliding frames 12 is the distance between the hinge plates 312 and the hinge plates 313 between the mother-child combination frames 3 connected to the end of the photovoltaic panel 2.

[0060] It should be noted that: In the present invention, the mother-child installation frame can, according to actual use, set the shape of the L-shaped mother-child frame to convex or T-shaped, so as to be applicable to the connection of four groups of photovoltaic panels 2 at the same time, and change the connection between the photovoltaic panels 2 to a parallel connection. This usage method needs to be used according to the actual use environment. For example, when installing the photovoltaic panels 2 on a plane, there is no need to adjust the installation angle of the photovoltaic panels 2, so that all the photovoltaic panels 2 are completely installed horizontally and can be used in parallel.

[0061] When the angle of the photovoltaic panel 2 needs to be adjusted, the L-shaped mother and son frame can be used to connect the photovoltaic panels 2 in series.
