DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0036] See also Figure 1-Figure 4 , which shows a structural schematic diagram of a photovoltaic folding mechanism for self-circulating water supply in deserts provided by the present invention.

[0037] As can be seen from the figures, the photovoltaic folding mechanism for desert self-circulating water supply provided by the present invention includes three components: a box 100, a plurality of photovoltaic folding units 200, and two sets of lifting mechanisms 300.

[0038] Among them, the box body 100 is the main structure, used to carry other components;

[0039] Furthermore, the box 100 is provided with an open end;

[0040] The photovoltaic folding unit 200 is composed of a first photovoltaic module 210 and a second photovoltaic module 220. The bottom and top of the first photovoltaic module 210 and the second photovoltaic module 220 are both provided with rollers 211b. The top of the first photovoltaic module 210 and the top of the second photovoltaic module 220 are connected by a hinge assembly. The first photovoltaic module 210 and the second photovoltaic module 220 can rotate along the hinge assembly so that both are parallel to the horizontal plane to form an unfolded state and both are perpendicular to the horizontal plane to form a folded state.

[0041] The photovoltaic folding units 200 are placed in the box body 100 in a folded state through the open end in sequence. The first photovoltaic assembly 210 is arranged away from the open end, and the second photovoltaic assembly 220 is arranged close to the open end. The first photovoltaic assembly 210 is provided with a connecting groove 211c on both sides. The two sets of lifting mechanisms 300 are movably arranged inside the box body 100 and located on both sides of the photovoltaic folding units 200, and can move along the photovoltaic folding units 200.

[0042] The lifting mechanism 300 is provided with a rotating pin 370 corresponding to the side connection groove of the first photovoltaic component 210. The two lifting mechanisms 300 can be detachably connected to the connection grooves 211c on both sides of the first photovoltaic component 210 through the rotating pin 370. The first photovoltaic component 210 in a vertical state can be rotated along the bottom roller to gradually become horizontal through the driving of the lifting mechanism, and the second photovoltaic component 220 can be rotated along the hinge assembly and follow the first photovoltaic component 210 to gradually become horizontal until the first photovoltaic component 210 and the second photovoltaic component 220 are both horizontal and form an unfolded state. The lifting mechanism 300 can unfold several folded photovoltaic folding units 200 into an unfolded state in sequence by moving in the box 100.

[0043] Specifically, the box body 100 is a rectangular box body, and an opening 110 is provided on one side of the box body 100 for allowing a plurality of photovoltaic folding units 200 to enter and exit. Square holes 120 are provided on the sides of the box body 100 on both sides of the opening 110 .

[0044] Furthermore, two sets of lifting mechanisms 300 are symmetrically arranged on one side of the square hole 120 on both sides of the box body 100. The lifting mechanism 300 includes a guide groove 310, a cross bar 320, a force transmission bracket 330, a lifting arm 340, a push-pull rod 350, and a driving device 360.

[0045] The guide groove 310 is fixed to one side of the box 100. The guide groove 310 is located on one side of the photovoltaic units 200 and the length direction of the guide groove 310 is consistent with the arrangement direction of the photovoltaic folding units 200. The guide groove 310 is provided with a plurality of bolt holes 311 with equal spacing.

[0046] The two ends of the crossbar 320 are respectively connected to the hole wall of the square hole 120. The crossbar 320 is located above the guide groove 310 and is parallel to the guide groove 310. The force transmission bracket 330 is movably arranged on the guide groove 310.

[0047] The force transmission bracket 330 formed by connecting two plates is fixed to the guide groove 310 and the cross bar 320 and can slide along the guide groove 310 and the cross bar 320. After sliding to a predetermined position, the bolts are passed through the bolt holes 311 on the guide groove 310 to abut against the force transmission bracket 330, so that the force transmission bracket 330 and the guide groove 310 are reliably fixed.

[0048] The force transmission bracket 330 is connected to one end of the lifting arm 340 and the push-pull rod 350 through a rotating shaft and a sliding hinge. One end of the push-pull rod 350 is hinged to the lifting arm 340, and the other end is connected to the driving device 360. The driving device 360 ​​drives the lifting arm 340 to rise and fall by adjusting the length of the push-pull rod 350, thereby forming a lifting mechanism.

[0049] A rotating latch 370 is provided at the other end of the lifting arm 340 , and the rotating latch 370 can be rotated to extend and connect to the connecting groove 211 c or retract and disconnect from the connecting groove 211 c.

[0050] The above-mentioned rotating latch 370 is conventional technology and will not be described in detail here. The rotating latch 370 can control the extension length of the latch by rotating the rotating handle clockwise or counterclockwise. When the latch is extended, it can be relatively fixed in position by pressing against the notch of the connecting groove 211c, thereby ensuring that the lifting arm 340 can reliably drive the photovoltaic folding unit 200 to fold and unfold through the connecting groove 211c. After folding and unfolding, the connection is disconnected by retracting the latch.

[0051] Furthermore, the first photovoltaic assembly 210 and the second photovoltaic assembly 220 have the same structure, and both include a mounting frame 211, a plurality of mounting keels 212, and a plurality of photovoltaic panels 213. The plurality of mounting keels 212 are vertically connected to the mounting frame 211 in sequence, and the plurality of photovoltaic panels 213 correspond to the mounting keels 212 and are connected to the mounting keels 212.

[0052] The mounting frame 211 is welded from four C-shaped channel steels. To enhance the rigidity of the frame, several oblique reinforcement braces 211a are provided inside the frame 211.

[0053] Two sets of rollers 211b are symmetrically provided at the top and bottom of the mounting frame 211, respectively, for allowing the mounting frame 211 to move;

[0054] Connecting grooves 211 c are symmetrically provided on both sides of the mounting frame 211 of the first photovoltaic module 210 . The connecting grooves 211 c are preferably C-shaped connecting grooves.

[0055] The hinge assembly includes four connecting plates 231, which are respectively located on both sides of the two groups of rollers 211b at the top of the mounting frame 211 in the first photovoltaic component 210 and the two groups of rollers 211b at the top of the mounting frame 211 in the second photovoltaic component 220. The two ends of the connecting plates 231 are respectively movably connected to the top rollers 211b of the mounting frame 211 in the first photovoltaic component 210 and the top rollers 211b of the mounting frame 211 in the second photovoltaic component 220, so as to movably connect the first photovoltaic component 210 and the second photovoltaic component 220.

[0056] Furthermore, in order to improve the reliability of the photovoltaic folding unit 200 in the folded state, limited locking buckles 211 d are respectively connected to both sides of the mounting frame 211 .

[0057] like Figure 5As shown, the limiting lock buckle 211d is composed of an inner and outer ring buckle, which can respectively form a first slot 211e and a second slot 211f. The first slot 211e and the second slot 211f on the two adjacent limiting lock buckles 211d are connected by fasteners, thereby fixing the first photovoltaic component 210 and the second photovoltaic component 220. The fastener can be a hinge, an E-shaped fastener, etc.

[0058] Furthermore, the photovoltaic folding mechanism for self-circulating water supply in the desert provided by the present invention also includes two sets of slide rails, which correspond to the two sets of rollers 211b at the bottom of the mounting frame 211, respectively, and the rollers 211b can move thereon. The slide rails are used to set the slide rails at the bottom of the roller 211b when the lifting mechanism 300 unfolds the photovoltaic folding unit 200, so as to guide the movement of the roller 211b.

[0059] Based on the photovoltaic folding mechanism for desert self-circulating water supply constructed in the above scheme, this scheme also provides a construction method. The construction steps are as follows:

[0060] S1: Before the mechanism is deployed, two slide rails must be laid on the ground in advance. The slide rails can be installed and fixed on site, or laid flat inside the container room, and then rolled out in sequence and effectively connected.

[0061] S2: The force transmission bracket 330 moves along the guide groove 310 to the photovoltaic folding unit 200 closest to the opening 110, and is effectively fixed to the guide groove 310 by fasteners passing through the bolt holes 311. The lifting arm 340 is raised to the height corresponding to the side connection groove 211c of the mounting frame 211 of the first photovoltaic module 210 and the rotating pin 370 is screwed in.

[0062] S3: Open the limit lock 211d of the photovoltaic folding unit 200, and drive the push-pull rod 350 to extend and retract through the driving device 360, driving the lifting arm 340 to rise and fall, and slowly lowering the first photovoltaic assembly 210 and the second photovoltaic assembly 220 of the photovoltaic folding unit 200 to a horizontal position, forming an unfolded state;

[0063] S4: Unscrew the rotating latch 370, move the force transmission bracket 330 along the guide groove 310 to the side of the adjacent photovoltaic folding unit 200, lift the lifting arm 340 to the position corresponding to the connecting groove 211c on the side of the mounting frame 211 of the first photovoltaic module 210, screw in the rotating latch 370, and repeat the S3 process to unfold the photovoltaic folding unit 200;

[0064] S5: Repeat S4 to unfold all the photovoltaic folding units 200. When the mechanism changes from the unfolded state to the overlapping state, the above steps can be performed in reverse order.
