Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a portable photovoltaic module carrying strap. Background Technology

[0002] Photovoltaic modules are devices composed of multiple solar cells encapsulated with materials. The main function of photovoltaic modules is to directly convert solar energy into electrical energy. During the transportation and installation of photovoltaic modules, some installation areas have narrow passages that make it impossible to transport the photovoltaic modules mechanically. Therefore, the photovoltaic modules need to be manually moved to the installation area.

[0003] The manual handling of photovoltaic modules mostly involves lifting or carrying them on one's back. However, carrying photovoltaic modules on one's back can result in poor stability and movement, causing the modules to sway from side to side while walking. This affects the stability and efficiency of the handling process and may even lead to the risk of tipping over. Utility Model Content

[0028] like Figure 1-10 In this invention, a portable photovoltaic module carrying strap includes a carrying strap body 1. Two positioning shoulder straps 2 are provided on one side of the carrying strap body 1, and each of the four corners of the other side of the carrying strap body 1 is provided with a connecting strap 4. Each connecting strap 4 is provided with a connecting buckle 5 at its end. The connecting buckle 5 is used to fasten the through holes 1801 at the four corners of the photovoltaic module frame 18. Two cross-arranged connecting straps 14 are also provided. The lower end of each connecting strap 14 is connected to each connecting strap 4 below it. The upper end of each connecting strap 14 is connected to each connecting strap 4 above it through a connecting ring 13. Each connecting strap 14 is provided with an adjustment handle 12 at its upper end. The photovoltaic module is placed between the connecting strap 14 and the carrying strap body 1.

[0029] After placing the photovoltaic module between the junction belt 14 and the main body of the back strap 1 and fastening the connecting buckle 5, the worker carries the main body of the back strap 1 on the other side of the back strap 1 using the positioning shoulder strap 2. The worker then adjusts the upper end of the adjustment buckle 12 to the front and pulls one adjustment buckle 12 with each hand to adjust the diagonal position of the photovoltaic module frame 18 to prevent imbalance.

[0030] In the preferred embodiment, a limiting strap 6 is connected between the two positioning shoulder straps 2.

[0031] In the preferred embodiment, the lower part of the shoulder strap body 1 is provided with a positioning waist belt 9.

[0032] In the preferred embodiment, the main body 1 of the strap is provided with a second protective air cushion 15 on the side near the photovoltaic module frame 18.

[0033] In the preferred embodiment, the side of the strap body 1 away from the photovoltaic module frame 18 is provided with a thickened pad 3 and a first protective air cushion 7.

[0034] In a preferred embodiment, the connecting buckle 5 includes a spring-limiting lock 16, which includes a hook portion 501. One end of the hook portion 501 is provided with a stop 502, and the other end of the hook portion 501 is provided with a rotatable spring-limiting lock 16. The middle part of the spring-limiting lock 16 is provided with a compression spring 503 connected to the inner side of the hook portion 501, and the end of the swing rod 504 abuts against the stop 502.

[0035] In a preferred embodiment, the main body 1 of the shoulder strap is provided with a keel assembly 19. The keel assembly 19 includes a central shaft 1901. Multiple keel pieces 20 are arranged alternately on both sides of the central shaft 1901. The keel pieces 20 have an H-shaped structure. Multiple branch pieces 2001 are provided at both ends of the keel pieces 2001. Each branch piece 2001 has a sleeve portion 2002 at its end. The sleeve portion 2002 at one end of the keel piece 20 is rotatably sleeved on the central shaft 1901. The end of an adjacent keel piece 20 away from the keel assembly 19 is provided with a connecting shaft 21. The connecting shaft 21 is rotatably sleeved with the sleeve portions 2002 of the two keel pieces 20 that are close to each other.

[0036] The keel plate 20 has a sheet-like structure with a certain width in the vertical direction, thus possessing good vertical load-bearing capacity to meet the requirements for handling photovoltaic modules. The two sides of the keel plate 20 can form a certain angle. Based on this, the keel plate 20 can bend and deform appropriately and recover in the thickness direction. When the connecting shaft 21 connects two adjacent branch plates 2001 on the same side, the side of the keel plate 20 away from the keel module 19 is no longer able to swing independently, but is connected to the adjacent keel plate 20, while retaining a certain degree of flexible deformation capacity to conform to the curve of the person's back. Therefore, the main body 1 of the carrying strap can bear the heavy photovoltaic modules without large structural deformation, and the carrying is also relatively comfortable for the staff.

[0037] In a preferred embodiment, the inner side of the main body 1 of the shoulder strap is provided with a plurality of buckle portions 101, and each keel piece 20 passes through each buckle portion 101.

[0038] The load force received by the main body 1 is transmitted to each keel piece 20 through the buckle part 101, making the keel assembly 19 the main force-bearing component.

[0039] In the preferred embodiment, the keel assembly 19 has keel pieces 20 at its four corners, the connecting block 22 has connecting holes 2201, and a connecting shaft 23 is also provided. The connecting shaft 23 passes through the connecting holes 2201, and the two ends of the connecting shaft 23 are respectively fitted with positioning shoulder straps 2 and connecting straps 4.

[0040] Large-diameter stop caps are provided at both ends of the connecting shaft 23.

[0041] The weight of the photovoltaic module borne by the connecting strap 4 is directly transferred to the positioning shoulder strap 2 through the connecting shaft 23, which avoids the positioning shoulder strap 2 and the connecting strap 4 from tearing at the sewn part of the back strap body 1 due to excessive force.

[0042] In a preferred embodiment, one end of the positioning shoulder strap 2 and the connecting strap 4 is provided with a reinforcing ring 24, and the two ends of the connecting shaft 23 are respectively sleeved with the reinforcing rings 24 of the positioning shoulder strap 2 and the connecting strap 4.

[0043] The reinforcing ring 24 is made of metal and has a larger contact area with the connecting shaft 23, which can withstand greater force and prevent the connecting shaft 23 from tearing at the perforations in the positioning shoulder strap 2 and the connecting strap 4.

[0044] Example 2: like Figure 1-5 A portable photovoltaic module carrying strap includes a carrying strap body 1, with positioning shoulder straps 2 fixedly connected to both sides of the top of the carrying strap body 1, and shoulder strap mounting buckles 8 fixedly connected to the ends of the positioning shoulder straps 2, positioning waist belts 9 fixedly connected to the bottom of both sides of the carrying strap body 1, and waist belt mounting buckles 10 fixedly connected to the ends of the positioning waist belts 9, with a thickened pad 3 fixedly connected to the front end of the carrying strap body 1, and a first protective air cushion 7 fixedly connected to the front end of the thickened pad 3, with connecting straps 4 fixedly connected to the four corners of the rear end of the carrying strap body 1, with connecting buckles 5 fixedly connected to the ends of the connecting straps 4, and spring limit lock buckles 16 fixedly connected inside the connecting buckles 5, with a transfer strap 14 fixedly connected to the connecting straps 4, and an adjustment handle buckle 12 fixedly connected to the end of the transfer strap 14, and a second protective air cushion 15 fixedly connected to the rear end of the carrying strap body 1; The connecting strap 4 is an adjustable length back strap. Each connecting strap 4 is equipped with an adjustment buckle 11. There are four sets of connecting straps 4, and the connecting buckles 5 are respectively fastened into the holes at the four mounting corners of the photovoltaic module. Specifically, such as Figure 1 and Figure 4 As shown, first place the photovoltaic module on the main body 1 of the shoulder strap, then fasten the connecting buckle 5 on the four mounting corner holes of the photovoltaic module. The spring limit lock 16 on the connecting buckle 5 can achieve stable locking and fixing. Then tie the transfer strap 14 to the outside of the photovoltaic module. After that, put the main body 1 of the shoulder strap on your body and use the positioning shoulder strap 2 and positioning waist belt 9 to tie it tightly and move it stably.

[0045] A connecting ring 13 is fixedly connected to the connecting strap 4, and a cross strap 14 passes through the connecting ring 13. Two sets of cross straps 14 are provided. The cross straps 14 are cross-tied to the outside of the photovoltaic module. A limit strap 6 is fixedly connected to the side of the positioning shoulder strap 2, and a limit buckle 17 is fixedly connected to the end of the limit strap 6. Specifically, such as Figure 1 and Figure 3 As shown, when moving photovoltaic modules, first attach the connecting buckles 5 on the four sets of connecting straps 4 to the corner holes of the photovoltaic modules, and then cross-tie the transfer straps 14 to the outside of the photovoltaic modules. After the transfer straps 14 pass through the connecting rings 13, the movers can hold the adjusting handles 12. During the moving process, the photovoltaic modules can be adjusted by pulling the adjusting handles 12 left and right to avoid the photovoltaic modules being misaligned and affecting the moving effect.

[0046] The first protective air cushion 7 is provided in two sets, and the second protective air cushion 15 is made of cushioning rubber pad. The first protective air cushion 7 and the second protective air cushion 15 are made of the same material. Specifically, such as Figure 1 and Figure 2 As shown, before moving photovoltaic modules, the movers need to put on the back strap 1. The first protective air cushion 7 on the back strap 1 fits against the mover's back. The photovoltaic modules are placed on the back strap 1 and fit against the second protective air cushion 15. The thickened pad 3 on the back strap 1 and the first protective air cushion 7 can enhance the comfort of moving photovoltaic modules.

[0047] Working principle: First, place the photovoltaic module on the carrying strap body 1. Then, fasten the connecting buckle 5 to the four mounting corner holes of the photovoltaic module. The spring limit lock 16 on the connecting buckle 5 can achieve stable locking and fixation. Then, tie the connecting strap 14 to the outside of the photovoltaic module. After that, put on the carrying strap body 1 and use the positioning shoulder strap 2 and positioning waist belt 9 to fix it for stable movement. The first protective air cushion 7 on the carrying strap body 1 is in contact with the back of the mover. The photovoltaic module is placed on the carrying strap body 1 and is in contact with the second protective air cushion 15. The thickened pad 3 and the first protective air cushion 7 on the main body of the carrying strap 1 can enhance the comfort of carrying photovoltaic modules. When carrying photovoltaic modules, first attach the connecting buckles 5 on the four sets of connecting straps 4 to the corner holes of the photovoltaic modules, and then cross-tie the cross straps 14 to the outside of the photovoltaic modules. After the cross straps 14 pass through the connecting rings 13, the workers can hold the adjusting buckles 12. During the carrying process, the photovoltaic modules can be adjusted by pulling the adjusting buckles 12 left and right, so as to avoid the photovoltaic modules being misaligned and affecting the carrying effect. This structure realizes the function of easy adjustment of photovoltaic modules.

[0048] The structure consists of a main body, positioning shoulder straps, connecting straps, connecting buckles, positioning waist belts, and spring limit locks. First, the photovoltaic module is placed on the main body of the carrying strap. Then, the connecting buckles are fastened to the four mounting corner holes of the photovoltaic module. The spring limit locks on the connecting buckles can achieve stable locking and fixation. Then, the connecting straps are tied to the outside of the photovoltaic module. Finally, the main body of the carrying strap is put on the body and the positioning shoulder straps and positioning waist belts are used to tighten and fix it, so that it can be moved stably. This structure realizes the function of facilitating stable handling. By incorporating a carrying strap, adjustable buckles, connecting rings, and a transfer strap, when transporting photovoltaic modules, the connecting buckles on the four sets of connecting straps are first attached to the corner holes of the photovoltaic module. Then, the transfer straps are crossed and tied to the outside of the photovoltaic module. After the transfer straps pass through the connecting rings, the transporter can hold the adjustable buckles and adjust the position of the photovoltaic module by pulling the adjustable buckles left and right during the transport process. This prevents the photovoltaic module from being misaligned and affecting the transport efficiency. This structure enables easy adjustment of the photovoltaic module. By incorporating a carrying strap, a thickened pad, a first protective air cushion, and a second protective air cushion, the transporter needs to wear the carrying strap before moving the photovoltaic modules. The first protective air cushion on the carrying strap fits against the transporter's back, and the photovoltaic modules are placed on the carrying strap and fit against the second protective air cushion. The thickened pad and the first protective air cushion on the carrying strap enhance the comfort of moving the photovoltaic modules. This structure achieves the function of improving the comfort of handling.
