It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] See also Figure 1 For the sake of clear description, X in the figure represents the horizontal direction, and Y represents the longitudinal direction. An embodiment of the present application provides a photovoltaic device, including a column 4, a load-bearing cable 3, a photovoltaic panel 2 and a connecting device 1. The column 4 is fixed to the ground or a mountain, and a plurality of load-bearing cables 3 are arranged on the column 4 at intervals. A plurality of photovoltaic panels 2 are laid along the length direction of the load-bearing cable 3. The connecting device 1 is used to fix the photovoltaic panel 2 to the load-bearing cable 3.

[0041] See also Figure 2In practical applications, two load-bearing cables 3 are usually used, and multiple columns 4 are arranged at intervals along the longitudinal direction. Two load-bearing cables 3 are arranged at intervals on multiple columns 4 along the transverse direction. Multiple photovoltaic panels 2 are laid on the load-bearing cables 3 along the longitudinal direction. In order to fix the photovoltaic panel 2 on the load-bearing cables 3, four installation points 21 can be set on the photovoltaic panel 2. The four installation points 21 are symmetrically arranged on the opposite sides of the photovoltaic panel 2. A connecting device 1 is provided at the position corresponding to each installation point 21 on the load-bearing cable 3. The installation point 21 on the photovoltaic panel 2 is connected to the connecting device 1 accordingly, so that the photovoltaic panel 2 is fixed to the load-bearing cable 3, and the assembly of the photovoltaic equipment is completed.

[0042] See also Figure 3 and Figure 4 The connection device 1 comprises a clamping structure 10, a clamping member 20 and a connecting member 30. The clamping structure 10 is provided with a first fixing hole 1011, an adjustment groove 1012 and a locking groove S. The adjustment groove 1012 is used to fix the photovoltaic panel 2, and the locking groove S is used for the load-bearing cable 3 to pass through and clamp the load-bearing cable 3. The clamping member 20 is provided with a second fixing hole 203, which corresponds to the first fixing hole 1011. The clamping member 20 is used to press the photovoltaic panel 2 against the clamping structure 10. The connecting member 30 passes through the second fixing hole 203 and the first fixing hole 1011 to fix the clamping member 20 and the clamping structure 10. The connecting member 30 can be a bolt and nut structure.

[0043] In practical applications, see Figure 7 First, the clamping structure 10 is set on the load-bearing cable 3 through the locking groove S, the photovoltaic panel 2 is provided with an installation point 21, and the clamping structure 10 is provided with an adjustment groove 1012 corresponding to the installation point 21. The clamping structure 10 also includes a fastener 104, and the fastener 104 passes through the installation point 21 and the adjustment groove 1012 to fix the photovoltaic panel 2 and the clamping structure 10 together, and then the second fixing hole 203 of the clamping member 20 corresponds to the first fixing hole 1011 on the clamping structure 10, the clamping member 20 is arranged above the photovoltaic panel 2, and the second fixing hole 203 and the first fixing hole 1011 are passed through the connecting member 30 from top to bottom, and the clamping member 20 is pressed against the photovoltaic panel 2, and the photovoltaic panel 2 is further pressed against the clamping structure 10, so that the photovoltaic panel 2 is confined between the clamping member 20 and the clamping structure 10, thereby enhancing the connection stability between the photovoltaic panel 2 and the load-bearing cable 3. The fasteners 104 may be bolts and nuts. In some other embodiments, other fixing structures may also be used, which is not limited in the present application.

[0044] Compared with the prior art, the clamping structure 10 of the present application is provided with an adjustment groove 1012, which corresponds to the installation point 21 on the photovoltaic panel 2 to realize the installation positioning function of the photovoltaic panel 2, and then the photovoltaic panel 2 is pressed against the clamping structure 10 through the clamping member 20, so as to further enhance the connection stability between the photovoltaic panel 2 and the load-bearing cable 3, and the structure is simple and the construction is convenient; the photovoltaic equipment using this connection device effectively shortens the construction period and saves economic costs.

[0045] See also Figure 8 , X represents the width direction of the adjustment plate 101 , which is also the above-mentioned lateral direction, Y represents the length direction of the adjustment plate 101 , which is also the above-mentioned longitudinal direction, and Z represents the height direction of the adjustment plate 101 .

[0046] The adjustment groove 1012 extends along the width direction of the adjustment plate 101 and is used to adjust the connection position between the adjustment plate 101 and the photovoltaic panel 2 .

[0047] In actual applications, since the installation point 21 of the photovoltaic panel 2 is fixed, that is, along the lateral direction, the distance between the two installation points 21 of the photovoltaic panel 2 is fixed. When the construction site is in a mountainous area or encounters a period of large wind load, the load-bearing cable 3 will be twisted, resulting in a change in the lateral spacing between the load-bearing cables 3. Since the connecting device 1 is fixed on the load-bearing cable 3, the lateral distance between the two connecting devices 1 also changes. If the connecting device 1 on the load-bearing cable 3 in a natural state corresponds to the installation point 21, then the relative position of the connecting device 1 on the load-bearing cable 3 and the installation point 21 changes after the twisting. At this time, if the adjustment groove 1012 is not extended, the adjustment groove 1012 cannot be connected to the corresponding installation point 21, resulting in the inability to install the photovoltaic panel 2. In order to avoid this situation, the present application extends the adjustment groove 1012 to a certain length in the lateral direction so that it can accommodate a larger range of lateral distances. This range can meet the changes in the lateral distance of the load-bearing cable 3 caused by most terrains, so that the installation point 21 can always be located within this range, thereby meeting the installation requirements of the photovoltaic panel 2 on the load-bearing cable 3 at different lateral distances.

[0048] It should be noted that the two load-bearing cables 3 are symmetrical, and the connecting devices 1 arranged on the two load-bearing cables 3 can be symmetrical or in the same direction. The symmetrical setting can meet the change in the lateral distance of the load-bearing cables 3 caused by the large slope of the terrain, and the same direction setting can meet the change in the lateral distance of the load-bearing cables 3 caused by the small slope of the terrain. The present application does not limit this.

[0049] See also Fig. 9The clamping structure 10 includes an adjusting plate 101 and a clamping member 102. The adjusting plate 101 and the clamping member 102 are detachably connected. The adjusting plate 101 is provided with a first fixing hole 1011 and an adjusting groove 1012. The adjusting plate 101 is used to connect with the photovoltaic panel 2. A first arc groove 1013 is provided on the side of the adjusting plate 101 close to the clamping member 102. A second arc groove 1022 is provided on the side of the clamping member 102 close to the adjusting plate 101. The first arc groove 1013 and the second arc groove 1022 are enclosed to form a locking groove S.

[0050] In actual application, the clamping member 102 and the adjusting plate 101 are respectively clamped on the load-bearing cable 3 from opposite sides, so that the load-bearing cable 3 is located in the locking groove S formed by the first arc groove 1013 and the second arc groove 1022, and then the clamping member 102 and the adjusting plate 101 are locked, so that the two can be tightly squeezed on the load-bearing cable 3 from opposite sides. Through this squeezing force, the fixing effect of the clamping structure 10 and the load-bearing cable 3 is achieved, and the clamping structure 10 is prevented from sliding on the load-bearing cable 3, thereby further achieving the fixation of the connecting device 1 and the load-bearing cable 3.

[0051] See also Fig.10 The clamping structure 10 includes an anti-slip protrusion 103 , and the groove wall of the first arc-shaped groove 1013 is provided with an anti-slip protrusion 103 ; and / or, the groove wall of the second arc-shaped groove 1022 is provided with an anti-slip protrusion 103 .

[0052] In one embodiment, the first arc groove 1013 and the second arc groove 1022 are both provided with anti-skid protrusions 103, which can strengthen the friction between the clamping structure 10 and the load-bearing cable 3, making the connection between the two more stable, and further limiting the sliding of the clamping structure 10 relative to the load-bearing cable 3. The anti-skid protrusions 103 can be tooth-shaped or block-shaped, which is not limited in the present application.

[0053] See again Fig.10 The above-mentioned clamping member 102 includes a first connecting end 1024 and a second connecting end 1025, the second arc groove 1022 is respectively connected to the first connecting end 1024 and the second connecting end 1025, and at least a portion of the first connecting end 1024 is overlapped on the adjustment plate 101; the second connecting end 1025 is provided with a third fixing hole 1021, and the third fixing hole 1021 corresponds to the first fixing hole 1011. The connecting member 30 passes through the third fixing hole 1021 and the first fixing hole 1011 to fix the second connecting end 1025 and the adjustment plate 101 together.

[0054] Specifically, the first connecting end 1024 includes a first part G1, a second part G2 and a third part G3, the first part G1 is connected to the second arc groove 1022, the second part G2 is connected to the first part G1, and extends along the height direction of the adjustment plate 101 in the direction away from the first part G1, the third part G3 is connected to the second part G2, and overlapped on the adjustment plate 101, and the connection between the clamping member 102 and one side of the adjustment plate 101 is achieved by overlapping; the second connecting end 1025 is provided with a third fixing hole 1021, and the connecting member 30 is penetrated by the first fixing hole 1011 and the third fixing hole 1021 to fix the second connecting end 1025 and the adjustment plate 101, and the connection between the clamping member 102 and the other side of the adjustment plate 101 is achieved by the connecting member 30. Compared with the prior art, the clamping member 102 of the present application is connected to one side of the adjustment plate 101 by overlapping. On the one hand, there is no need to open a fixing hole on this side of the adjustment plate 101, which increases the area of ​​the adjustment plate 101 and can effectively reduce the design area of ​​the adjustment plate 101, saving steel. On the other hand, it can save the number of connecting members 30 used, effectively saving the amount of steel used.

[0055] It can be understood that, in one embodiment, a connecting member 30 can be passed through the second fixing hole 203, the first fixing hole 1011 and the third fixing hole 1021 in sequence to fix the clamping member 20, the adjustment plate 101 and the clamping member 102 together, further saving the use of the connecting member 30.

[0056] The first connection end 1024 is provided with a clamping groove 1023 , the adjustment plate 101 is clamped with the clamping groove 1023 , and at least a portion of the first connection end 1024 overlaps the adjustment plate 101 .

[0057] The inner surfaces of the first part G1, the second part G2 and the third part G3 are combined to form a snap-fitting groove 1023, and at least a portion of the adjustment plate 101 is inserted into the snap-fitting groove 1023, so that the third part G3 can be overlapped on the adjustment plate 101. At the same time, the clamping effect of the snap-fitting groove 1023 can also enhance the connection stability between the clamping member 102 and the adjustment plate 101.

[0058] See also Fig.11 The clamping member 102 also includes a first tooth portion 1026. At least part of the groove wall of the clamping groove 1023 is provided with the first tooth portion 1026. The adjustment plate 101 is provided with a second tooth portion 1014 at a position corresponding to the first tooth portion 1026. The first tooth portion 1026 and the second tooth portion 1014 are meshed to clamp the clamping member 102 and the adjustment plate 101.

[0059] Specifically, a first tooth portion 1026 is provided on a side of the third portion G3 facing the adjustment plate 101, and a second tooth portion 1014 is provided on a side of the adjustment plate 101 facing the third portion G3. When the adjustment plate 101 is inserted into the snap-in groove 1023, the first tooth portion 1026 engages with the second tooth portion 1014 to prevent the adjustment plate 101 from escaping from the snap-in groove 1023. There are multiple first tooth portions 1026 and second tooth portions 1014, and the height of the first tooth portion 1026 on the third portion G3 gradually increases along the direction approaching the second portion G2, and the height of the second tooth portion 1014 on the adjustment plate 101 gradually increases, so that the angle between the meshing point of the first tooth portion 1026 and the second tooth portion 1014 and the height direction of the adjustment plate 101 is less than 90 degrees, thereby further enhancing the connection stability between the adjustment plate 101 and the snap-in groove 1023 and preventing the adjustment plate 101 from escaping from the snap-in groove 1023.

[0060] See also Fig.14 and Fig.15 The pressing member 20 includes a first pressing block 201 and a second pressing block 202 . The first pressing block 201 is used to fix two adjacent photovoltaic panels 2 , and the second pressing block 202 is used to fix a single photovoltaic panel 2 .

[0061] In actual applications, since multiple photovoltaic panels 2 are laid in sequence along the length direction of the load-bearing cable 3, the installation positions of the connecting device 1 and the photovoltaic panel 2 are divided into two situations. One is that the connecting device 1 is installed between two adjacent photovoltaic panels 2. The connecting device 1 here needs to connect two adjacent photovoltaic panels 2 at the same time. Therefore, the clamping piece 20 in the connecting device 1 here adopts the first pressing block 201. Specifically, the first pressing block 201 includes a first pressing plate 2011 and a first main body 2012. The first main body 2012 is provided with a second fixing hole 203 for fixing to the adjusting plate 101. The first pressing plates 2011 are connected to the opposite sides of the first main body 2012. At this time, adjustment grooves 1012 are provided on the opposite sides of the adjusting plate 101, which are used to respectively connect to the installation points 21 of two adjacent photovoltaic panels 2. The first pressing plate 2011 extends along the length direction of the load-bearing cable 3 toward the adjacent photovoltaic panels 2, and is used to press the two adjacent photovoltaic panels 2 against the adjusting plate 101, so that the multiple photovoltaic panels 2 are connected as a whole, so that they will not be easily damaged when sucked by wind.

[0062] The other is that the connecting device 1 is connected to the photovoltaic panel 2 on the outermost side of the load-bearing cable 3 . In this case, only one side of the connecting device 1 is the photovoltaic panel 2 . The connecting device 1 here uses a second pressing block 202 . Specifically, the second pressing block 202 includes a second pressing plate 2021, a second main body 2022 and a supporting portion 2023. The second main body 2022 is provided with a second fixing hole 203 for fixing to the adjusting plate 101. The second main body 2022 is connected to the side of the photovoltaic panel 2 close to the second pressing plate 2021. The second pressing plate 2021 extends along the length direction of the load-bearing cable 3 toward the direction close to the photovoltaic panel 2 and is used to press the single photovoltaic panel 2 against the adjusting plate 101; the second main body 2022 is connected to the side away from the photovoltaic panel 2 with the supporting portion 2023. The supporting portion 2023 extends toward the direction close to the adjusting plate 101 and abuts against the adjusting plate 101. Through the abutment between the supporting portion 2023 and the adjusting plate 101, the photovoltaic panel 2 is supported, so that the photovoltaic panel 2 will not be easily damaged when the wind load is large.

[0063] By providing the first pressing block 201 and the second pressing block 202 and using different pressing blocks at different connection positions, the amount of steel used can be further saved, while effectively increasing the practicality of the device.

[0064] It can be understood that the contact portion between the supporting portion 2023 and the adjusting plate 101 is chamfered to facilitate stress release and avoid stress concentration from damaging the adjusting plate 101 .

[0065] See again Fig.14 and Fig.15 The clamping member 20 is provided with a U-shaped groove N, and the U-shaped groove N includes a groove bottom N1 and groove walls N2 connected to the opposite sides of the groove bottom N1, and the groove bottom N1 is provided with a second fixing hole 203, and the connecting member 30 includes an end portion 302 and a rod portion 301 connected to each other; wherein the rod portion 301 passes through the second fixing hole 203 and the first fixing hole 1011 to fix the clamping member 20 and the clamping structure 10, and the end portion 302 abuts against the groove bottom N1 and is clamped with the groove wall N2.

[0066] In one embodiment, see Fig.12The connector 30 also includes a fastening nut 303. The rod 301 of the connector 30 passes through the second fixing hole 203, the first fixing hole 1011 and the third fixing hole 1021 in sequence.
