Description

Technical Field

[0001] This invention relates to the field of photovoltaic ribbon technology, specifically to a wire storage device for changing photovoltaic ribbon rolls. Background Technology

[0002] Photovoltaic solder ribbon, also known as tin-plated copper ribbon or tin-coated copper ribbon, is divided into busbars and interconnecting strips. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity and concentrating energy. In use, photovoltaic solder ribbon is usually wound on a reel.

[0003] Existing reels have a simple structure, and multiple reels are placed together. This means that when changing reels, workers usually lift the reels with one hand, which carries a considerable risk of dropping them. Photovoltaic welding ribbon is different from other cables. If it falls, it will cause gaps between the welding ribbon and the reel, leading to problems such as loose welding ribbon wiring and wire jamming when customers start production. The same problem will also occur when the photovoltaic welding ribbon reels are placed vertically. To address this, we propose a wire storage device for changing photovoltaic welding ribbon reels.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, those skilled in the art who have not made any innovative embodiments are all within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figure 1-10 The present invention provides a technical solution: a wire storage device for photovoltaic ribbon reel replacement, comprising a wire reel body 1 and side plates 2 disposed on both sides of the wire reel body 1, wherein a cover plate 21 is disposed on the side plate 2, and further comprising: an O-ring 3 disposed in the side plate 2 and a transverse connecting mechanism 7 disposed in the side plate 2, wherein the transverse connecting mechanism 7 cooperates with the O-ring 3 to achieve transverse connection between different cover plates 21, and a longitudinal connecting mechanism 8 disposed in the side plate 2, wherein the longitudinal connecting mechanism 8 cooperates with the O-ring 3 to achieve longitudinal connection between different cover plates 21.

[0037] The transverse connecting mechanism 7 includes a support rod 71 that penetrates the surface of the cover plate 21. One end of the support rod 71 is provided with a wedge block 74, which is disposed inside the side plate 2. The other end of the support rod 71 is provided with a push block 72, which has multiple inclined surfaces. One of the cover plates 21 is provided with a second embedding block 6. The support rod 71 is connected to multiple embedding components 73 through the push block 72. The embedding components 73 are disposed inside the second embedding block 6.

[0038] The embedded component 73 includes a sliding block 731, which is slidably disposed within the second embedded block 6. One end of the sliding block 731 is provided with an inclined surface, which is parallel to the inclined surface opened on the actuating block 72. The other end of the sliding block 731 is provided with an embedded rod 733, which penetrates through the side wall of the second embedded block 6. A return spring 732 is provided between the sliding block 731 and the second embedded block 6, and the return spring 732 is sleeved on the surface of the embedded rod 733.

[0039] By providing multiple inclined surfaces on the actuating block 72, multiple sliding blocks 731 can be simultaneously contacted when the actuating block 72 moves. The inclined surfaces on the sliding blocks 731 allow the sliding blocks 731 to move in a specified direction when contacted. Displacement is generated by the contact between the inclined surfaces, thus avoiding excessive costs due to the linkage structure of other instruments. The reset spring 732 ensures that the embedded rod 733 can be reset when the sliding blocks 731 are not under force.

[0040] The longitudinal connecting mechanism 8 includes a second support rod 81 that penetrates the surface of the cover plate 21. A second wedge block 82 is provided at one end of the second support rod 81 and is located inside the side plate 2. A mounting block 83 is provided at the other end of the second support rod 81. A groove is provided on the mounting block 83. A first embedded block 5 is slidably mounted on the mounting block 83. A connecting spring 84 is provided between the mounting block 83 and the first embedded block 5 and is located in the groove of the mounting block 83. A second return spring 85 is provided between the second wedge block 82 and the cover plate 21 and is sleeved on the surface of the second support rod 81. By sliding the first embedded block 5 on the mounting block 83, it can be ensured that the first embedded block 5 can be moved to both sides by the support rod 81. By placing the connecting spring 84 in the groove of the mounting block 83, the space occupied by the connecting spring 84 can be avoided.

[0041] The O-ring 3 is slidably disposed inside the side plate 2. A connecting block 31 is provided at the upper end of the O-ring 3. The connecting block 31 penetrates through the cover plate 21. After penetrating the cover plate 21, a lifting handle 4 is provided. Multiple pressing blocks 32 are provided on the O-ring 3. The O-ring 3 abuts against the first wedge 74 and the second wedge 82 through the pressing blocks 32. By setting the O-ring 3 as an O-shaped structure and fitting it onto the main body of the reel 1, the movement distance of the O-ring 3 can be limited.

[0042] The side plate 2 has a receiving cavity 22, and the transverse connecting mechanism 7, the longitudinal connecting mechanism 8 and the O-ring 3 are all set in the receiving cavity 22.

[0043] The main body 1 of the reel penetrates the side wall of the side plate 2 and extends into the receiving cavity 22. O-rings 3 are fitted at both ends of the main body 1 of the reel.

[0044] The cover plate 21 has a clearance groove 211, and the connecting block 31 passes through the cover plate 21 through the clearance groove 211. The cover plate 21 has a longitudinal connecting groove 212, and the first embedding block 5 can be embedded in the longitudinal connecting groove 212. One of the cover plates 21 has a transverse connecting groove 213, and the second embedding block 6 can be embedded in the transverse connecting groove 213. Holes are provided on both sides of the transverse connecting groove 213, and the embedding rod 733 can be embedded in its holes. The width of the second embedding block 6 can be appropriately increased to ensure that there is enough space between the main bodies 1 of the coil to lift the handle 4 when the second embedding block 6 is embedded in the transverse connecting groove 213.

[0045] The second embedded block 6 and the transverse connecting groove 213 are not located on the same cover plate 21.

[0046] In use, by pulling the first embedding block 5 to both sides a certain distance and pulling the first embedding block 5 forward, the connecting spring 84 is stretched, thereby embedding the first embedding block 5 into the longitudinal connecting groove 212 on the other cover plate 21. At this time, the other pair of cover plates 21 are clamped by the first embedding blocks 5 on both sides, realizing the longitudinal connection between different coil bodies 1. By embedding the second embedding block 6 into the transverse connecting groove 213 and embedding the embedding rod 733 into the hole of the transverse connecting groove 213, the transverse connection between different coil bodies 1 can be realized.

[0047] When it is necessary to separate multiple coil bodies 1, by pulling the lifting handles 4 on both sides, the position of the lifting handles 4 rises. At this time, the O-rings 3 rise synchronously under the action of the lifting handles 4. This causes the squeezing blocks 32 to press against the wedges 82 and 74, causing the support rods 71 ​​and 81 to move. This moves the mounting blocks 83 to both sides, causing the first embedded block 5, which is slidably set on the mounting blocks 83, to release its clamping grip on another coil body 1, thus separating the two longitudinally connected coil bodies 1. Furthermore, as the O-ring 3 rises, the support rod 71 abuts against the sliding block 731 through the push block 72. The inclined surface on its surface causes the sliding blocks 731 on the other two sides to move inward, disengaging the sliding blocks 731 from the holes of the transverse connecting groove 213. This allows the transversely connected coil body 1 to be separated. Thus, when multiple coil bodies 1 are connected and placed, both lifting handles 4 need to be lifted simultaneously to separate the coil body 1 from the other coil bodies 1, thereby avoiding the risk of dropping when lifting with one hand during coil replacement.

[0048] Example 2

[0049] Please see Figure 1-12 The present invention provides a technical solution: a storage device for photovoltaic ribbon rewinding, wherein embodiment 2 is an optimization based on embodiment 1;

[0050] Both the longitudinal connecting groove 212 and the first embedded block 5 are configured as a fan-shaped structure.

[0051] By setting the longitudinal connecting groove 212 and the first embedded block 5 as a fan-shaped structure, it is not necessary to make the longitudinal connecting groove 212 completely fit the shape of the first embedded block 5. This avoids the longitudinal connecting groove 212 being too close to the center of the cover plate 21, which would cause the first embedded block 5 to extend too long to connect with the longitudinal connecting groove 212. This makes it easier to connect the first embedded block 5 with the longitudinal connecting groove 212.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
