Description

Technical Field

[0001] This invention relates to the field of fixing device technology, and in particular to a photovoltaic module fixing belt and fastening device. Background Technology

[0002] Transportation refers to the logistics activity of moving goods from one location to another using specific equipment and tools. It involves the spatial displacement of goods within different geographical areas to change their spatial position, thereby creating spatial benefits, realizing their use value, and meeting diverse societal needs. Transportation is one of the central links in logistics and a crucial function of modern logistics activities. During transportation, goods are secured with straps. Photovoltaic modules refer to devices assembled from multiple photovoltaic cells, used to convert sunlight into electrical energy. Photovoltaic modules typically include encapsulation materials to protect the internal cells and withstand environmental factors.

[0003] When transporting photovoltaic panels, multiple photovoltaic panels are usually stacked together to reduce the space required for transportation, thereby reducing transportation costs. In order to prevent the photovoltaic panels from collapsing after being stacked, a fixing structure is used to fix the photovoltaic panels. However, the fixing structure of existing transportation equipment is not only relatively complex and difficult to operate, but also occupies a lot of space, resulting in a limited number of photovoltaic panels that can be transported by the transportation equipment and high transportation costs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in operating the fixed structure of the transportation device, the large space occupied, the limited number of photovoltaic panels that can be transported, and the high transportation cost. Therefore, this invention proposes a photovoltaic module fixing belt and fastening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a photovoltaic module fixing strip, including a strip body, with connectors provided on both sides of the strip body;

[0007] The connector includes a connector and a plug. The connector is fixedly connected to the belt body. A connecting shaft is fixedly provided on the connector, and a limiting part is fixedly provided on the connecting shaft.

[0008] The plug is movably inserted into the connecting shaft, and the plug is disposed between the limiting part and the connector;

[0009] The plug has elastic portions symmetrically arranged on both sides, and the elastic portions are all arc-shaped structures.

[0010] The plug includes a connecting plate and a mounting plate, and the elastic part is fixedly disposed on the mounting plate.

[0011] Furthermore, a connecting groove is formed between the mounting plate and the connecting plate, and the end of the elastic part has a protrusion, and a deformation groove is formed between the protrusion and the mounting plate.

[0012] Furthermore, a plug plate is fixedly provided at one end of the connecting shaft, the plug plate is inserted into the connector, the plug plate is provided with a positioning groove, and the connector is provided with a positioning structure that cooperates with the positioning groove.

[0013] Furthermore, the positioning structure includes a positioning pin that is movably inserted into the connector, the positioning pin having a clearance groove corresponding to the insert plate, and a spring being provided between the positioning pin and the connector.

[0014] The present invention also proposes a photovoltaic module fixing strap fastening device, including the photovoltaic module fixing strap mentioned above, and a connecting sleeve. The connecting sleeve has a through groove that cooperates with the elastic part, and the end of the elastic part passes through the through groove and contacts the connecting sleeve.

[0015] Furthermore, a slot is provided on one side of the connecting sleeve, and a connector is inserted into the slot. The connector includes a connecting part for connecting with a bracket, a fixing frame or other structure that requires the installation of a fastening device, and a post that is movably inserted into the slot.

[0016] Furthermore, the insert post is provided with multiple slots in an array, and an elastic plate is fixedly connected to the connecting sleeve. The elastic plate is fixedly provided with a card that cooperates with the slot.

[0017] Furthermore, the slot is provided with an inclined surface, and the elastic plate is fixedly provided with a protrusion that facilitates movement.

[0018] Furthermore, the connecting sleeve is provided with a sliding groove, on which the connecting sleeve is slidably disposed, and a limiting frame that cooperates with the protrusion is fixedly disposed on one side of the connecting sleeve.

[0019] The photovoltaic module fixing strip and fastening device proposed in this invention have the following advantages:

[0020] In this invention, the connecting heads at both ends of the belt are connected to the fastening device to form a strap structure, which is used to bind and fix the stacked photovoltaic modules. The operation is simple and occupies little space, enabling the transport of larger volumes and more photovoltaic panels, thus reducing transportation costs.

[0021] Secondly, in this invention, the connector part of the connector is connected to the plug through the connecting shaft. After the plug is inserted and fixed with the fastening device, the angle of the belt can be adjusted by rotating the connector to achieve different angles for binding and fixing the stacked photovoltaic modules, thereby improving the applicability.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-3 A photovoltaic module fixing strip includes a strip body 1, and connectors 2 are provided on both sides of the strip body 1;

[0030] The connector 2 includes a connector 21 and a plug 22. The connector 21 is fixedly connected to the belt body 1. A connecting shaft 23 is fixedly provided on the connector 21. A limiting part 24 is fixedly provided on the connecting shaft 23.

[0031] The plug 22 is movably inserted into the connecting shaft 23, and the plug 22 is located between the limiting part 24 and the connector 21;

[0032] The plug 22 is symmetrically arranged with elastic parts 25 on both sides, and the elastic parts 25 are all arc-shaped structures.

[0033] In this invention, the connectors 2 at both ends of the belt body 1 are connected to the fastening device on the transport equipment to form a binding structure, which binds and fixes the stacked photovoltaic panels. The connector 21 of the connector 2 is connected to the plug 22 through the connecting shaft 23. After the plug 22 is inserted and fixed with the fastening device, the angle of the belt body 1 can be adjusted by rotating the connector 21 to bind and fix the stacked photovoltaic panels at different angles, thereby improving the applicability. Multiple fixing belts can be used to form a cross-shaped structure or an X-shaped structure, etc. Compared with the traditional cross-shaped binding belt, the fixing effect is better, and it can fix photovoltaic modules of different shapes.

[0034] Furthermore, in this embodiment, the plug 22 includes a connecting plate 221 and a mounting plate 222. The elastic part 25 is fixedly disposed on the mounting plate 222. When the plug 22 is inserted into the fastening device, the mounting plate 222 is first inserted into the fastening device, and the elastic part 25 undergoes elastic deformation. When the plug 22 is installed in place, the elastic part 25 resets and cooperates with the fastening device to fix the plug 22 and prevent it from loosening.

[0035] In this embodiment, a connecting groove is formed between the mounting plate 222 and the connecting plate 221. The end of the elastic part 25 has a protrusion 251, and a deformation groove is formed between the protrusion 251 and the mounting plate 222. When the plug 22 is inserted into the fastening device, the elastic part 25 undergoes elastic deformation, and the deformation groove becomes smaller until the protrusion 251 contacts the mounting plate 222. At this time, the plug 22 is partially inserted into the fastening device. Continue to insert the plug 22 until it is fully inserted, the elastic part 25 resets, and the deformation groove recovers.

[0036] Furthermore, in this embodiment, a plug plate 231 is fixedly provided at one end of the connecting shaft 23. The plug plate 231 is plugged into the connector 21. A positioning groove 232 is provided on the plug plate 231. A positioning structure 3 that cooperates with the positioning groove 232 is provided on the connector 21. When the plug 22 or the connecting shaft 23 is damaged, the plug plate 231 and the connecting shaft 23 can be removed and replaced, which is more convenient.

[0037] In this embodiment, the positioning structure 3 includes a positioning pin 31 that is movably inserted into the connector 21. The positioning pin 31 has a relief groove corresponding to the insert plate 231. A spring 32 is provided between the positioning pin 31 and the connector 21. Under the action of the spring 32, the relief groove on the positioning pin 31 is misaligned with the insert plate 231. When replacing the plug 22 or the connecting shaft 23, the positioning pin 31 is pressed so that the relief groove corresponds with the insert plate 231, and the insert plate 231 can be removed to replace the plug 22 or the connecting shaft 23.

[0038] In this embodiment, the strap 1 of the fixing strap is tied to the stacked photovoltaic modules, and the connectors 2 at both ends of the fixing strap are respectively inserted into two fastening devices to fix the stacked photovoltaic modules.

[0039] Reference Figure 4-5 The present invention also proposes a photovoltaic module fixing belt fastening device, including the photovoltaic module fixing belt mentioned above, and a connecting sleeve 4. The connecting sleeve 4 has a through groove that cooperates with the elastic part 25. The end of the elastic part 25 passes through the through groove and contacts the connecting sleeve 4.

[0040] It should be noted that, in this embodiment, a slot is provided on one side of the connecting sleeve 4, and a connector 5 is inserted into the slot. The connector 5 includes a connecting part 51 for connecting with structures that require fastening devices, such as brackets and fixing frames, and a plug 52 that is movably inserted into the slot. By adjusting the position of the plug 52, the position of the connecting sleeve 4 is changed, thereby changing the position of the connector 2. The range of the wrapping of the belt 1 can be adjusted according to the needs, and photovoltaic panels of different specifications can be wrapped.

[0041] Furthermore, in this embodiment, the insert post 52 is provided with a plurality of slots 521 in an array, and the connecting sleeve 4 is fixedly connected with an elastic plate 41. The elastic plate 41 is fixedly provided with a clip that cooperates with the slot 521. Under the action of the elastic plate 41, the clip is inserted into the slot 521. At this time, the connection state between the connecting sleeve 4 and the insert post 52 will not change, preventing the connecting sleeve 4 from being pulled upward by the fixing strap.

[0042] In this embodiment, the slot 521 is provided with an inclined surface 522, and the elastic plate 41 is fixedly provided with a protrusion 42 for easy movement. When fixing the photovoltaic module, the fixing strap is tied to the stacked photovoltaic module, and then the connectors 2 at both ends of the fixing strap are inserted into the two connecting sleeves 4. By moving the two connecting sleeves 4 downward, the two connectors 2 are moved downward, thereby tightly binding the fixing strap to the stacked photovoltaic panels and fixing the stacked photovoltaic panels. When the connecting sleeves 4 move downward, the clip abuts against the inclined surface 522 of the slot 521, and the elastic plate 41 undergoes elastic deformation, which does not hinder the downward movement of the connecting sleeves 4. When the fixing strap meets the required fixing strength, the downward movement of the connecting sleeves 4 is stopped. At this time, the clip abuts against the non-inclined surface of the slot 521 and cannot move upward, maintaining the fixing strength of the fixing strap for the photovoltaic module.

[0043] More specifically, in this embodiment, the connecting sleeve 4 is provided with a sliding groove, and the connecting sleeve 6 is slidably disposed on the sliding groove. A limiting frame 61 that cooperates with the protrusion 42 is fixedly disposed on one side of the connecting sleeve 6. By moving the connecting sleeve 6, the limiting frame 61 covers the protrusion 42, thereby ensuring that the protrusion 42 and the elastic plate 41 will not move, so that the clip is tightly connected to the slot 521 to prevent loosening, thereby preventing the connecting sleeve 4 from moving upward.

[0044] Operating procedure: During operation, the fixing strap is tied to the stacked photovoltaic modules. Then, the connectors 2 at both ends of the fixing strap are inserted into the two connecting sleeves 4. During insertion, the elastic part 25 undergoes elastic deformation until the protrusion 251 contacts the mounting plate 222. At this point, the plug 22 is partially inserted into the fastening device. Continue inserting the plug 22 until it is fully inserted. The elastic part 25 returns to its original position, tightly connecting the connector 2 and the connecting sleeve 4. By moving the two connecting sleeves 4 downward, the two connectors 2 are moved downward, thus tightly binding the fixing strap to the stacked photovoltaic modules. On the photovoltaic board, the stacked photovoltaic panels are fixed, and when the connecting sleeve 4 moves down, the clip abuts against the inclined surface 522 of the slot 521. The elastic plate 41 undergoes elastic deformation, which does not hinder the downward movement of the connecting sleeve 4. When the fixing strap meets the required strength for fixing, the downward movement of the connecting sleeve 4 is stopped. By moving the connecting sleeve 6, the limiting frame 61 covers the protrusion 42, thereby ensuring that the protrusion 42 and the elastic plate 41 will not move, so that the clip is tightly connected to the slot 521 to prevent loosening, thereby preventing the connecting sleeve 4 from moving up.
