Detailed Implementation

[0031] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0032] This utility model discloses a four-fold deployable support structure for a squad-level photovoltaic energy storage power supply, comprising a container 1, a primary folding mechanism, a secondary folding mechanism, and a tertiary folding mechanism; the specific structure is as follows: Figures 1 to 7 As shown, the container 1 is a horizontally arranged hollow cuboid structure with open sides. Inside the container 1, there are vertically spaced primary folding mechanisms that match each other. The upper and lower ends of each primary folding mechanism are horizontally slidably connected to the inner top and bottom surfaces of the container 1, respectively, so that the primary folding mechanism can be pushed forward or pulled out of the container 1. On the right side of the front primary folding mechanism and the left side of the rear primary folding mechanism, there are vertically arranged secondary and tertiary folding mechanisms, respectively. Each tertiary folding mechanism folds into the corresponding secondary folding mechanism, and then each secondary folding mechanism folds onto the corresponding primary folding mechanism, thus moving with the primary folding mechanism in a pushing and pulling motion.

[0033] like Figures 1 to 7 As shown, the front-side first-level folding mechanism pushes or pulls out the container 1 from the right side, and the rear-side first-level folding mechanism pushes or pulls out the container 1 from the left side; the left and right sides of the container 1 are also equipped with matching hatches in a double-opening manner, and the interior of the container 1 is protected by the hatches, and it is ensured that the opening of the hatches does not interfere with the action of the first-level folding mechanism to push or pull out the container 1.

[0034] like Figures 1 to 7 As shown, inside the cabin 1, I-beams 2 are horizontally arranged relative to the upper and lower surfaces of each first-level folding mechanism, and the length of each I-beam 2 is consistent with the internal horizontal length of the cabin 1; the two upper I-beams 2 are fixedly connected to the inner top surface of the cabin 1, and the two lower I-beams 2 are fixedly connected to the inner bottom surface of the cabin 1, ensuring that the two opening slots of each I-beam 2 are arranged front and back.

[0035] Each primary folding mechanism of this utility model includes a primary frame 3, a connecting frame 19, a pulley block 4, a first limiting block 5, a second limiting block 22, and a stop block 23; for example...Figures 1 to 7 As shown in the drawings, the inside of the shelter 1 is also provided with a vertical transverse first frame 3 between the positions of every two I-beams 2, and a connecting frame 19 is vertically aligned between the left ends and the right ends of every two adjacent first frames 3, respectively, and a vertical transverse cuboid structure is formed by splicing the connecting frames 19; three horizontal longitudinal pulley blocks 4 are sequentially and spaced apart along the length direction of the first frame 3 at the upper and lower edges of every two adjacent first frames 3, and the two ends of each pulley block 4 are rotatably connected to the corresponding first frame 3 around its own axis, and the setting positions of the pulley blocks 4 are all in the same horizontal plane as the opening groove positions of the corresponding I-beams 2, so that the first frame 3 is horizontally and transversely slid along the shelter 1 by the horizontal sliding of the pulley blocks 4 along the opening groove of the corresponding I-beam 2.

[0036] As shown in the drawings, Figures 1 to 7 A first limiting block 5 is vertically arranged at the top end position of the left side surface of the two front first frames 3 and at the top end position of the right side surface of the two rear first frames 3, respectively, and the upper end of each first limiting block 5 extends vertically upward out of the horizontal plane of the upper surface of the corresponding first frame 3, and every two adjacent first limiting blocks 5 are arranged on the front and rear sides of the corresponding I-beam 2 and do not interfere with the horizontal transverse sliding of the corresponding first frame 3, so that the right limiting of the pulling-out action of the front first folding mechanism out of the shelter 1 is achieved by the abutting cooperation of the front two first limiting blocks 5 and the top end of the right side surface of the shelter 1, and the left limiting of the pulling-out action of the rear first folding mechanism out of the shelter 1 is achieved by the abutting cooperation of the rear two first limiting blocks 5 and the top end of the left side surface of the shelter 1.

[0037] As shown in the drawings, Figures 1 to 7 A second limiting block 22 is vertically arranged at the bottom end position of the left side surface of the two front first frames 3 and at the bottom end position of the right side surface of the two rear first frames 3, respectively, and the lower end of each second limiting block 22 extends vertically downward out of the horizontal plane of the lower surface of the corresponding first frame 3, and every two adjacent second limiting blocks 22 are arranged on the front and rear sides of the corresponding I-beam 2 and do not interfere with the horizontal transverse sliding of the corresponding first frame 3; a stop block 23 is arranged at the left side edge of the inner bottom surface of the shelter 1 relative to the position of the rear two second limiting blocks 22 and at the right side edge of the inner bottom surface of the shelter 1 relative to the position of the front two second limiting blocks 22, respectively, and each stop block 23 does not interfere with the horizontal transverse sliding of the corresponding first frame 3, so that the right limiting of the pulling-out action of the front first folding mechanism out of the shelter 1 is achieved by the abutting cooperation of the front two second limiting blocks 22 and the corresponding stop block 23, and the left limiting of the pulling-out action of the rear first folding mechanism out of the shelter 1 is achieved by the abutting cooperation of the rear two second limiting blocks 22 and the corresponding stop block 23.

[0038] The positions of the leftmost pulley group 4 on the front-side primary folding mechanism and the rightmost pulley group 4 on the rear-side primary folding mechanism must ensure that the pulley group 4 does not disengage from the corresponding I-beam 2 when the primary folding mechanism is pulled out to the limit position.

[0039] like Figures 1 to 7 As shown, lock holes 6 matching the lock rod are embedded at intervals on the upper edge of the outer surface of each primary frame 3. Square steel I7 is vertically installed on the right side of the two front primary frames 3 and the left side of the two right primary frames 3. The height of each square steel I7 corresponds to the height of the corresponding primary frame 3, and its inner surface is in the same vertical plane as the outer surface of the corresponding primary frame 3. Each square steel I7 is horizontally hinged to the corresponding primary frame 3 within a 90° range on one side of the corresponding primary frame 3. Square steel II12 of the same specification is vertically aligned and fixed on the side away from the corresponding primary frame 3. This allows the square steel II12 and square steel I7 to rotate horizontally from a vertical horizontal state to a vertical longitudinal state towards the outer surface of the corresponding primary frame 3.

[0040] Each secondary folding mechanism of this utility model includes a secondary frame 8, a locking plate 9, and an insert block I 10; such as Figures 1 to 7 As shown, on the right side of the two primary frames 3 at the front and the left side of the two primary frames 3 at the rear, there are corresponding secondary frames 8 arranged vertically and horizontally. Each square steel II 12, on the side away from the corresponding square steel I 7, is horizontally hinged to the corresponding secondary frame 8 within a 90° range via hinges. Thus, when the square steel II 12 and square steel I 7 rotate horizontally to a vertical longitudinal position, each secondary frame 8 is parallel and aligned, spaced apart on the outer surface of the corresponding primary frame 3. The lower surface of each secondary frame 8 is on the same horizontal plane as the lower surface of the corresponding primary frame 3, and its upper surface is located below the upper surface of the corresponding primary frame 3. Furthermore, its upper surface is further divided relative to each lock hole 6. A locking plate 9 is provided. On the front surface of each locking plate 9, a first through hole matching the locking rod is vertically embedded and opened at the corresponding lock hole 6. When the secondary folding mechanism is folded onto the corresponding primary folding mechanism, the locking rod, locking plate 9 and lock hole 6 are inserted and cooperated to ensure the stability of the primary folding mechanism, secondary folding mechanism and tertiary folding mechanism when folded together. On the upper surface of the two secondary frames 8 on the right side and the upper surface of the two secondary frames 8 on the left side, there are horizontally inserted blocks I10. Each inserted block I10 is located on the side of the corresponding locking plate 9 away from the primary frame 3, and a second through hole matching the inserted rod 11 is vertically embedded and opened on its right side.

[0041] Each of the three-stage folding mechanisms of this utility model includes a three-stage frame 13, a square steel III 14, and an insert block II 15; as shown in the figure Figures 1 to 7 As shown, on the right side of the two front secondary frames 8 and the left side of the two rear secondary frames 8, a matching tertiary frame 13 is vertically and horizontally aligned. Between each tertiary frame 13 and the corresponding secondary frame 8, a square steel III 14 with the same specifications as square steel I 7 is vertically positioned. The height of each square steel III 14 corresponds to the height of the corresponding secondary frame 8, and its inner surface is in the same vertical plane as the outer surface of the corresponding secondary frame 8. Each square steel III 14 is horizontally hinged to the corresponding secondary frame 8 within a 90° range on one side and to the corresponding tertiary frame 13 within a 90° range on the other side. This allows the square steel III 14 to rotate horizontally from a vertical and horizontal state to a vertical and longitudinal state towards the outer surface of the corresponding secondary frame 8, and the tertiary frames 13 are parallel and aligned at intervals on the outer side of the outer surface of the corresponding secondary frame 8.

[0042] like Figures 1 to 7 As shown, on the upper surface of the two front-side tertiary frames 13, on the left side, and on the upper surface of the two rear-side tertiary frames 13, on the right side, there are horizontally arranged insert blocks II 15. Each insert block II 15 is coaxially arranged with the corresponding insert block I 10, and on its left side, a third through hole matching the insert rod 11 is also coaxially and vertically inserted. Thus, through the insertion and cooperation of the insert rod 11, insert block I 10 and insert block II 15, the stability of the secondary frame 8 and the tertiary frame 13 when unfolded is ensured.

[0043] like Figures 1 to 7As shown, two groups of vertical transverse photovoltaic assembly plates 17 are also respectively aligned and installed on the outer surface of each primary frame 3, the outer surface of secondary frame 8 and the outer surface of tertiary frame 13, and the lower ends of every adjacent two groups of photovoltaic assembly plates 17 are respectively vertically hinged by hinges; the upper end of each group of photovoltaic assembly plates 17 on the inner side is vertically hinged with the upper edge of the outer surface of the corresponding primary frame 3, secondary frame 8 and tertiary frame 13, and the upper end of each group of photovoltaic assembly plates 17 on the outer side is locked with the upper edge of the outer surface of the corresponding primary frame 3, secondary frame 8 and tertiary frame 13 in the folded state; a support foot 16 matched with the corresponding primary frame 3, secondary frame 8 and tertiary frame 13 is also respectively arranged on the lower surface of each primary frame 3, secondary frame 8 and tertiary frame 13, and the corresponding primary frame 3, secondary frame 8 and tertiary frame 13 are respectively supported and fixed by the support foot 16 in the unfolded state; a telescopic foot 18 matched with the corresponding photovoltaic assembly plate 17 is also respectively vertically arranged on the inner surface of each group of photovoltaic assembly plates 17 on the inner side near the lower end and on the outer surface of each group of photovoltaic assembly plates 17 on the outer side near the upper end, and the corresponding photovoltaic assembly plate 17 is respectively supported and fixed by the telescopic foot 18 in the unfolded state.

[0044] As shown, ​ The transverse width of each square steel I 7, square steel II 12 and square steel III 14 needs to ensure that the photovoltaic assembly plates 17 on the primary frame 3, the photovoltaic assembly plates 17 on the adjacent secondary frame 8 and the photovoltaic assembly plates 17 on the adjacent tertiary frame 13 do not interfere with each other in the folded state; a handle 20 is also vertically arranged between the right side surfaces of the two primary frames 3 on the front side and between the left side surfaces of the two primary frames 3 on the rear side, and each handle 20 is vertically fixedly connected with the corresponding connecting frame 19 and pushes and pulls the corresponding primary folding mechanism through the handle 20; a plurality of protective pads 21 are also uniformly and spacedly arranged on the inner surface of each group of photovoltaic assembly plates 17 on the inner side and on the outer surface of each group of photovoltaic assembly plates 17 on the outer side, and the corresponding photovoltaic assembly plates 17 are respectively protected by the protective pads 21 in the folded state, and it needs to be ensured that the protective pads 21 do not affect the work of the corresponding photovoltaic assembly plates 17.
