Description

Technical Field

[0001] The embodiments in this specification relate to the field of photovoltaic power generation technology, and in particular to a photovoltaic module connection structure and a photovoltaic array. Background Technology

[0002] In existing technologies, photovoltaic (PV) frames are typically fixed to PV brackets using mounting components, creating gaps between adjacent frames. However, in practical applications, PV arrays require drainage to meet installation needs. Related technologies often involve installing water channels in the gaps between adjacent frames to collect and drain water falling on the array. However, during heavy rain, the large water flow can cause splashes and overflows at the junctions of the channels, significantly reducing drainage effectiveness. Furthermore, the need for additional channels between PV modules complicates the structure and reduces installation efficiency.

[0003] Therefore, there is an urgent need for a photovoltaic module connection structure and a photovoltaic array to solve the above problems. Utility Model Content

[0004] The purpose of this specification is to provide a photovoltaic module connection structure and a photovoltaic array to improve the drainage effect of the photovoltaic module connection structure. Furthermore, the photovoltaic module connection structure is simple in structure and has high installation efficiency.

[0005] To achieve this objective, the embodiments in this specification adopt the following technical solutions:

[0006] A photovoltaic module connection structure, comprising:

[0007] At least two photovoltaic frames are provided, and at least two photovoltaic frames are spliced ​​together adjacently. In the two photovoltaic frames spliced ​​together adjacently, one of the photovoltaic frames is provided with a first slot, and the other photovoltaic frame is provided with a second slot. The first slot and the second slot together form a locking groove.

[0008] A locking insert is inserted and fixed in the locking groove.

[0009] As an optional solution, in two adjacent photovoltaic frames, one photovoltaic frame is provided with a first limiting groove communicating with the first slot, and the other photovoltaic frame is provided with a second limiting groove communicating with the second slot. The first limiting groove and the second limiting groove together form a limiting slot, and the size of the limiting slot is larger than the size of the locking groove.

[0010] One end of the locking insert is provided with a limiting part, the size of which is larger than the size of the locking insert, and the limiting part is inserted into the limiting slot.

[0011] As an optional solution, each of the photovoltaic frames is provided with a water guide channel and a flow guide plate on its first side. The water guide channel is connected to the locking groove, and the end of the water guide channel is connected to the flow guide plate.

[0012] As an optional solution, a flow-guiding slope is provided at the connection between the water guide channel and the flow guide plate.

[0013] As an optional solution, each of the photovoltaic frames has a water-blocking strip protruding from its first side, and the water-blocking strip covers the splicing point of two adjacent photovoltaic frames.

[0014] As an optional solution, each of the photovoltaic frames is provided with a water baffle on its side, and the side of the photovoltaic frame with the fastening strip inserted is arranged at an angle to the side of the photovoltaic frame with the water baffle.

[0015] As an optional solution, the end of the water baffle is provided with a positioning slot, and the positioning slots on two adjacent photovoltaic frames are interlocked.

[0016] As an optional solution, the photovoltaic module connection structure further includes:

[0017] Photovoltaic support system;

[0018] A fixing component is disposed on the photovoltaic frame, the fixing component being configured to fix the photovoltaic frame to the photovoltaic bracket.

[0019] As an optional solution, the fixing component includes:

[0020] A first pressing block is pressed against the photovoltaic frame and the photovoltaic bracket;

[0021] A connecting clamp passes through the first pressure block and is attached to the photovoltaic bracket;

[0022] A locking member is threadedly connected to the end of the connecting clamp that extends beyond the photovoltaic bracket.

[0023] A photovoltaic array includes photovoltaic modules and a photovoltaic module connection structure as described above, wherein a photovoltaic module is fixedly connected inside each of the photovoltaic frames.

[0024] As an optional solution, the photovoltaic module is positioned at a height lower than the photovoltaic frame, and a flow-guiding slope is provided at the connection between the photovoltaic module and the photovoltaic frame.

[0025] This specification provides a photovoltaic module connection structure, which includes a retaining strip and at least two photovoltaic frames. The at least two photovoltaic frames are joined adjacently. One of the adjacent photovoltaic frames has a first slot, and the other has a second slot. The first and second slots together form a retaining groove, and the retaining strip is inserted and fixed into the retaining groove. The photovoltaic module connection structure provided in this specification achieves the joint fixation of adjacent photovoltaic frames by joining them to form a retaining groove and inserting the retaining strip into it. This effectively reduces the gap between adjacent photovoltaic frames and improves drainage between them. Furthermore, this photovoltaic module connection structure only requires the retaining strip to be inserted and fixed into the retaining groove, eliminating the need for an additional water tank, resulting in a simple structure and high installation efficiency.

[0026] The embodiments of this specification also provide a photovoltaic array, which improves the drainage effect of the photovoltaic array by applying the above-described photovoltaic module connection structure, and has a simple structure and high installation efficiency.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this specification. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0054] Example 1

[0055] like Figures 1-4 As shown, this embodiment provides a photovoltaic module connection structure, which includes a photovoltaic bracket 4, a fixing component 5, and at least two photovoltaic frames 12. The at least two photovoltaic frames 12 are spliced ​​together adjacently, and the fixing component 5 is disposed on the photovoltaic frame 12. The fixing component 5 is used to fix the photovoltaic frame 12 to the photovoltaic bracket 4.

[0056] like Figure 1As shown, this embodiment also provides a photovoltaic array, which includes photovoltaic modules 20 and the aforementioned photovoltaic module connection structure. Each photovoltaic frame 12 has a photovoltaic module 20 fixedly connected inside it. Optionally, in this embodiment, the photovoltaic frame 12 and the photovoltaic module 20 can be fixed by adhesive bonding, or by clamping. This embodiment does not limit the specific fixing method between the photovoltaic frame 12 and the photovoltaic module 20.

[0057] Optionally, in this embodiment, multiple photovoltaic frames 12 are sequentially spliced ​​along the left-right direction in the figure, and multiple photovoltaic frames 12 are sequentially arranged along the front-back direction in the figure. It should be noted that, in this embodiment, during the assembly of the photovoltaic module connection structure, each photovoltaic frame 12 is first sequentially spliced ​​along the left-right direction on the front side of the photovoltaic support 4, and then a photovoltaic frame 12 is arranged on the back side of each spliced ​​photovoltaic frame 12, so that multiple photovoltaic frames 12 are arranged in an array on the photovoltaic support 4.

[0058] Optionally, in this embodiment, as Figure 1 As shown, each photovoltaic frame 12 is arranged at an angle, and one end of the photovoltaic frame 12 along the front-to-back direction is higher than the other end along the second direction. Exemplarily, this allows the front side of the photovoltaic frame 12 to be lower than the rear side, thereby ensuring that the photovoltaic module 20 fixed inside the photovoltaic frame 12 can receive more sunlight.

[0059] In this embodiment, as Figures 2-4 As shown, the fixing component 5 includes a first pressing block 51, a connecting clamp 52, and a locking member 53. The first pressing block 51 presses against the photovoltaic frame 12 and the photovoltaic bracket 4. The connecting clamp 52 passes through the first pressing block 51 and is fitted onto the photovoltaic bracket 4. The locking member 53 is threadedly connected to the end of the connecting clamp 52 that extends beyond the photovoltaic bracket 4. This structural design of the fixing component 5 enables a detachable connection of the photovoltaic frame 12 to the photovoltaic bracket 4, and the fixing component 5 has a simple structure and is easy to install. Optionally, in this embodiment, the connecting clamp 52 is a U-shaped clamp. The photovoltaic bracket 4 includes a support beam 41, and the end of the U-shaped clamp that extends beyond the support beam 41 is threadedly connected to the locking member 53. By designing the connecting clamp 52 as a U-shaped clamp, the stability and reliability of the U-shaped clamp's fixation on the support beam 41 are ensured. Optionally, in this embodiment, the lower part of the photovoltaic frame 12 is C-shaped, thereby ensuring the stability and reliability of the first pressing block 51 pressing against the photovoltaic frame 12.

[0060] Specifically, in this embodiment, as Figure 2 and Figure 3As shown, the locking component 53 includes a second pressure block 531 and a locking nut 532. The second pressure block 531 and the first pressure block 51 are arranged at intervals opposite to each other, and the first pressure block 51 and the second pressure block 531 are located on opposite sides of the support beam 41. The end of the connecting clamp 52, which passes through the first pressure block 51 and is attached to the support beam 41, passes through the second pressure block 531 and is threadedly connected to the locking nut 532. The end face of the locking nut 532 abuts against the second pressure block 531. The above-described structural design of the locking component 53 effectively ensures the stability of the fastening of the connecting clamp 52. In other embodiments, the locking component 53 can also be directly set in the form of a locking nut 532, so that the locking nut 532 abuts against the support beam 41 after being threadedly connected to the end of the connecting clamp 52.

[0061] In existing technologies, there are gaps between adjacent photovoltaic frames 12. However, in practical applications, photovoltaic arrays need to have drainage capabilities to meet customer installation requirements. In related technologies, water troughs are typically installed in the gaps between adjacent photovoltaic frames 12 to collect and drain water falling on the array. However, during heavy rain, due to the large water flow, water can still splash or overflow from the troughs at their junctions, significantly reducing the drainage effect. Furthermore, the need to install additional water troughs in the gaps between the photovoltaic frames 12 complicates the structure and reduces installation efficiency.

[0062] To solve the above problems, such as Figures 5-10 As shown, the photovoltaic module connection structure provided in this embodiment also includes a retaining strip 3. In two adjacent photovoltaic frames 12, one photovoltaic frame 12 has a first slot 125, and the other photovoltaic frame 12 has a second slot 126. The first slot 125 and the second slot 126 together form a retaining groove 127, and the retaining strip 3 is inserted and fixed in the retaining groove 127. The photovoltaic module connection structure provided in this embodiment, by splicing two adjacent photovoltaic frames 12 to form a retaining groove 127 and inserting and fixing the retaining strip 3 into the retaining groove 127, achieves splicing and fixing of two adjacent photovoltaic frames 12, effectively reducing the splicing gap between the two adjacent photovoltaic frames 12, thereby improving the drainage effect between the adjacent spliced ​​photovoltaic frames 12. Furthermore, this photovoltaic module connection structure only requires inserting and fixing the retaining strip 3 into the retaining groove 127 formed by splicing, eliminating the need for an additional water tank, making the structure simple and the installation efficiency high. It should be noted that in this embodiment, two photovoltaic frames 12 that are spliced ​​together in the left-right direction form a retaining groove 127.

[0063] It should be noted that in this embodiment, the photovoltaic frames 12 located in the middle are spliced ​​together by the fastening strips 3. The fixing component 5 only needs to fix the photovoltaic frames 12 located on the outer periphery to the photovoltaic bracket 4, which effectively reduces the number of fixing components 5 used, reduces the installation cost, and also effectively improves the installation efficiency of the entire photovoltaic module connection structure.

[0064] Specifically, when splicing two adjacent photovoltaic frames 12, the first photovoltaic frame 12 is first placed on the photovoltaic bracket 4, and then the second photovoltaic frame 12 is placed on one side of the first photovoltaic frame 12 in the left-right direction, so that the second photovoltaic frame 12 is close to the first photovoltaic frame 12 in the left-right direction until the first photovoltaic frame 12 and the second photovoltaic frame 12 are in contact with each other. At this time, the first slot 125 and the second slot 126 together form a locking groove 127. Finally, the locking strip 3 is inserted into the locking groove 127. The above settings make the splicing operation between two adjacent photovoltaic frames 12 simple and effectively avoid relative displacement and relative rotation between the two adjacent photovoltaic frames 12, ensuring the stability of the splicing between the two adjacent photovoltaic frames 12. Optionally, in this embodiment, the spliced ​​locking grooves 127 are arranged at an upward angle in the front and back, and the locking strips 3 are also inserted into the locking grooves 127 at a certain angle, which further avoids relative displacement and relative rotation between two adjacent photovoltaic frames 12 in the left and right directions.

[0065] In this embodiment, as Figure 6 and Figure 9As shown, in two adjacent photovoltaic frames 12, one photovoltaic frame 12 is provided with a first limiting groove 128 communicating with the first slot 125, and the other photovoltaic frame 12 is provided with a second limiting groove 129 communicating with the second slot 126. The first limiting groove 128 and the second limiting groove 129 together form a limiting slot, the size of which is larger than the size of the locking groove 127. One end of the locking strip 3 is provided with a limiting part 31, the size of which is larger than the size of the locking strip 3, and the limiting part 31 is inserted into the limiting slot. Specifically, when the locking strip 3 is inserted into the locking groove 127, the end of the locking strip 3 away from the limiting part 31 is inserted into the locking groove 127 until the limiting part 31 is inserted into the limiting slot, effectively preventing the locking strip 3 from sliding out of the locking groove 127 and ensuring the stability of the locking strip 3 in the locking groove 127. It should be noted that when it is necessary to disassemble two adjacent photovoltaic frames 12, the locking strip 3 can be pulled out from one end of the limiting part 31, making the operation convenient. Specifically, in this embodiment, the first limiting groove 128 is located at the high end of the first slot 125 in the front-back direction, and the second limiting groove 129 is located at the high end of the second slot 126 in the front-back direction. When the locking strip 3 is inserted, the end of the locking strip 3 away from the limiting part 31 is inserted into the locking groove 127 from the high end of the rear side, which effectively prevents the locking strip 3 from sliding out of the locking groove 127 towards the front side under its own weight.

[0066] In this embodiment, as Figures 5-7 As shown, each photovoltaic frame 12 has a water-blocking strip 124 protruding from its first side, and the water-blocking strip 124 covers the joint between two adjacent photovoltaic frames 12. By setting the water-blocking strip 124, the drainage effect at the joint between two adjacent photovoltaic frames 12 is effectively improved. Optionally, in this embodiment, each photovoltaic frame 12 has a water-blocking strip 124 protruding from one side along the left-right direction, and the water-blocking strip 124 covers the joint between two adjacent photovoltaic frames 12 along the left-right direction. Optionally, the water-blocking strip 124 is integrally formed with the photovoltaic frame 12, which not only simplifies the structure and facilitates installation, but also ensures the structural strength between the water-blocking strip 124 and the photovoltaic frame 12.

[0067] Optionally, such as Figures 5-10As shown, each photovoltaic frame 12 has a water baffle 2 on its side, and the side of the photovoltaic frame 12 with the fastening strip 3 inserted is arranged at an angle to the side of the photovoltaic frame 12 with the water baffle 2. Optionally, in this embodiment, the photovoltaic frame 12 has a water baffle 2 on its side along the front-back direction, and the water baffle 2 covers the contact point of two adjacent photovoltaic frames 12 along the front-back direction. By covering the contact point of two adjacent photovoltaic frames 12 along the front-back direction with the water baffle 2, the drainage effect of the contact point of two adjacent photovoltaic frames 12 along the front-back direction is effectively improved. Optionally, in this embodiment, each photovoltaic frame 12 has a water baffle 2 at its lower end along the front-back direction, and the photovoltaic frame 12 and the water baffle 2 are connected by a slope transition, thereby ensuring that the water baffle 2 covers and drains the contact point of two adjacent photovoltaic frames 12 along the front-back direction. Optionally, in this embodiment, the water baffle 2 and the photovoltaic frame 12 are integrally formed, which not only makes the structure simple and easy to install, but also ensures the structural strength between the water baffle 2 and the photovoltaic frame 12.

[0068] Optionally, in this embodiment, as Figure 5 and Figure 6 As shown, the height of the photovoltaic module 20 is lower than the height of the photovoltaic frame 12, and a drainage slope 30 is provided at the connection between the photovoltaic module 20 and the photovoltaic frame 12. This arrangement ensures that rainwater falling towards the splicing area of ​​the photovoltaic frame 12 is blocked by the water-blocking strip 124 and flows along the drainage slope 30 towards the lower-positioned photovoltaic module 20, preventing rainwater from seeping into the splicing gaps of the photovoltaic frame 12 and further guaranteeing the drainage effect of the water-blocking strip 124 at the splicing area.

[0069] In this embodiment, as Figures 6-9 As shown, the end of the baffle plate 2 is provided with a positioning slot 21, and the positioning slots 21 on two adjacent photovoltaic frames 12 are interlocked. This arrangement restricts the relative position of two adjacent photovoltaic frames 12 in the left-right direction along the front-back direction, thereby preventing relative displacement between the two adjacent photovoltaic frames 12 in the left-right direction along the front-back direction, ensuring the stability and reliability of the splicing between the two adjacent photovoltaic frames 12 in the left-right direction. Optionally, in this embodiment, the positioning slot 21 can be designed as an S-shape. In other embodiments, the positioning slot 21 can also be designed as a wave shape or a sawtooth shape.

[0070] Example 2

[0071] The photovoltaic module connection structure provided in this embodiment is basically the same as that in Embodiment 1. The difference between the photovoltaic module connection structure provided in this embodiment and that in Embodiment 1 is as follows:

[0072] like Figures 11-13As shown, each photovoltaic frame 12 has a water guide channel 121 and a guide plate 122 on its first side. The water guide channel 121 is connected to the retaining groove 127, and the end of the water guide channel 121 is connected to the guide plate 122. The above arrangement allows water that seeps into the splice of two adjacent photovoltaic frames 12 in the left-right direction to fall into the water guide channel 121, and flow from back to front in the water guide channel 121 to the guide plate 122 in the front-back direction. Then, it gradually flows along the guide plate 122 to the lower position (i.e., the front side) of the water guide channel 121, and finally flows out from the lowest position of the guide plate 122, thereby achieving the drainage effect at the splice. Moreover, the structure design is simple, and the water guide channel 121 and the guide plate 122 can be processed from the photovoltaic frame 12.

[0073] Optionally, in this embodiment, a guide plate 122 is connected to the lowest end of the water guide channel 121. In two adjacent photovoltaic frames 12 along the front-to-back direction, the guide plate 122 on the photovoltaic frame 12 at the higher position extends into the water guide channel 121 on the photovoltaic frame 12 at the lower position. This arrangement effectively avoids the problem of water leakage between two adjacent photovoltaic frames 12 along the front-to-back direction.

[0074] Optionally, in this embodiment, as Figures 11-13 As shown, a guide slope 123 is provided at the connection between the water guide channel 121 and the guide plate 122. By providing the guide slope 123, the water in the water guide channel 121 can be more smoothly guided to the guide plate 122 through the guide slope 123, ensuring that the guide plate 122 continues to collect the water into the water guide channel 121 located on the front side.

[0075] Optionally, in this embodiment, by designing the water guide channel 121 and the flow guide plate 122, it is unnecessary to set the water baffle 124 on the photovoltaic frame 12. In other embodiments, after designing the water guide channel 121 and the flow guide plate 122, the water baffle 124 can also be set on the photovoltaic frame 12.

[0076] Optionally, in this embodiment, as Figure 12 As shown, the water guide channel 121 and the second slot 126 are arranged adjacent to each other on the photovoltaic frame 12 in the left-right direction.

[0077] Example 3

[0078] The photovoltaic module connection structure provided in this embodiment is basically the same as that in Embodiment 2. The difference between the photovoltaic module connection structure provided in this embodiment and that in Embodiment 2 is as follows:

[0079] In this embodiment, as Figures 14-16As shown, the water guide channel 121 is formed at the bottom wall of the locking groove 127, thereby increasing the depth of the entire locking groove 127. Even after the locking strip 3 is inserted and fixed into the locking groove 127, the bottom of the locking groove 127 still contains the water guide channel 121. This allows water falling into the joint to pass through the locking groove 127 and then into the water guide channel 121. The water then flows from back to front in the water guide channel 121 to the guide plate 122, and gradually flows along the guide plate 122 towards the lower part (i.e., the front side) of the water guide channel 121, finally flowing out from the lowest point of the guide plate 122, thus achieving drainage at the joint. By forming the water guide channel 121 at the bottom wall of the locking groove 127 and deepening the locking groove 127, the structure is simple and easy to manufacture. It should be noted that in this embodiment, the bottom wall of the water guide channel 121 is flat, while the locking groove 127 is inclined, thereby preventing the locking strip 3 from blocking the water guide channel 121. Optionally, in this embodiment, the water guide channel 121 is formed at the bottom wall of the second slot 126.
