Description

Technical Field

[0001] The present application belongs to the field of photovoltaic technology, and in particular relates to a component cable structure and a photovoltaic system. Background Art

[0002] In photovoltaic systems, steel strands are usually used to fix and support photovoltaic module arrays. In environments with irregular slopes and variable topographical features such as mountains, steel strands also need to be able to adapt to variable steering requirements. For this reason, curved plates are often used to support the parts of the steel strands that need to be bent due to steering, to ensure that the steel strands can effectively transmit prestress. However, the design of curved plates can usually only adapt to steering angles within a specific range and cannot meet large-angle steering requirements (such as steering of more than 90 degrees). Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a component cable structure and a photovoltaic system, which utilizes the bending characteristics of the chain itself to make the axial directions of two adjacent steel strands spaced apart in the width direction of the side support beam different, which not only eliminates the need for using an arc plate but also quickly achieves the required steering angle of the steel strand and provides a larger steering angle, and also ensures that the steel strand does not need to bear bending stress, so that the steel strand always only bears tensile stress, further ensuring the reliability of the use of the steel strand.

[0054] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0055] Reference below Figure 1-Figure 8 The component cable structure provided in the embodiment of the present application is described. The component cable structure is applied to a photovoltaic system and provides support for a photovoltaic component 900 . The component cable structure includes a plurality of steel strands 110 and a plurality of chains 120 .

[0056] It should be noted that the photovoltaic bracket includes two side support beams 210 and at least one middle support beam 220. The two side support beams 210 are spaced apart along their width direction, and the middle support beam 220 is arranged between the two side support beams 210. The number of middle support beams 220 can be designed according to actual needs, and no specific restrictions are made in comparison with this embodiment.

[0057] A plurality of steel strands 110 are arranged at intervals, and the steel strands 110 are used to install the photovoltaic assembly 900 .

[0058] It can be understood that at least two steel strands 110 are arranged between the side supporting beam 210 and the middle supporting beam 220 near the end, and between two adjacent middle supporting beams 220, so that the same photovoltaic module 900 can be connected to two steel strands 110 at the same time, thereby ensuring the stability of the installation of the photovoltaic module 900.

[0059] It should be noted that the steel strand 110 refers to a helical steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It has a high elastic modulus and a low relaxation rate, and can adapt to large-span tensioning. The material of the steel strand 110 includes but is not limited to carbon steel or alloy steel. Among them, the cross-section and number of the steel strands 110 can be designed according to actual needs, and the lengths of the steel strands 110 can be completely the same or partially the same, and this embodiment does not impose specific restrictions on this.

[0060] Two adjacent steel strands 110 are connected by a chain 120, and the chain 120 is suitable for adjusting the angle formed by the axial directions of the two adjacent steel strands 110. It should be noted that the material of the chain 120 includes but is not limited to alloy steel or steel, and the lengths of the chains 120 can be completely the same or partially the same, and this embodiment does not impose specific restrictions on this.

[0061] It is understandable that at least two chains 120 are installed on the middle support beam 220 and are distributed at intervals along the length direction of the photovoltaic module 900, that is, two adjacent steel strands 110 along the width direction of the middle support beam 220 are connected by the chain 120, and then the bending characteristics of the chain 120 itself are used to make the axial directions of the two steel strands 110 connected to the chain 120 different, so as to ensure that the angle formed by the corresponding steel strands 110 can adapt to the complex terrain environment and provide a larger turning angle. Compared with the use of curved plates in related technologies to achieve the turning of the steel strands 110, the chain 120 replaces the part of the steel strand 110 that needs to be bent due to the turning, not only does it not need to use a curved plate, but it can also quickly achieve the required turning angle of the steel strand 110, and it can also ensure that the steel strand 110 does not need to bear bending stress, so that the steel strand 110 always only bears tensile stress, further ensuring the reliability of the use of the steel strand 110.

[0062] According to the component cable structure provided in the embodiment of the present application, the bending characteristics of the chain 120 itself are utilized to make the axial directions of two adjacent steel strands 110 spaced apart in the width direction of the side supporting beam 210 different. Not only can the required turning angle of the steel strand 110 be quickly achieved without the need for an arc plate, and a larger turning angle can be provided, but it can also ensure that the steel strand 110 does not need to bear bending stress, so that the steel strand 110 always only bears tensile stress, further ensuring the reliability of the use of the steel strand 110.

[0063] In some embodiments, Figures 1 to 5As shown, first connectors 130 are respectively provided at both ends of the chain 120, and a second connector 140 is provided at at least one end of the steel strand 110, and the first connector 130 and the second connector 140 are detachably connected. The connection between the first connector 130 and the steel strand 110 and the connection between the second connector 140 and the steel strand 110 include, but are not limited to, welding, threaded connection, rivet connection, pin connection or snap connection, etc.

[0064] It can be understood that, through the detachable connection between the first connecting member 130 and the second connecting member 140, the connection between the chain 120 and the steel strand 110 is achieved while simplifying the disassembly and assembly process, which facilitates transportation and can also achieve rapid adjustment of the steering and tension of the steel strand 110 in different terrains, thereby improving the adaptability and compatibility of the component cable structure.

[0065] It should be noted that, considering the need to apply pre-tightening force to the steel strands 110, if there is at least one side supporting beam 210 on which the chain 120 is not installed, the steel strands 110 among the multiple steel strands 110 close to the side supporting beam 210 on which the chain 120 is not installed is only provided with the second connecting member 140 at one end, and the other end is used to connect to the anchor 500.

[0066] In some embodiments, Figures 2 to 4 As shown, the outer wall of one of the first connecting member 130 and the second connecting member 140 is provided with a first external thread, and the inner wall of the other of the first connecting member 130 and the second connecting member 140 is provided with a first internal thread, and the first external thread and the first internal thread are threadedly connected.

[0067] It is understandable that in order to realize the detachable connection between the first connecting member 130 and the second connecting member 140, a first external thread is provided on the outer side wall of one of the first connecting member 130 and the second connecting member 140, and a first internal thread is provided on the inner side wall of the other, that is, the threaded connection between the first connecting member 130 and the second connecting member 140 is realized by screwing the first external thread and the first internal thread. Figure 2 As shown, the first internal thread is disposed on the inner side wall of the first connecting member 130, as shown in FIG. Figure 4 As shown, the first external thread is disposed on the outer side wall of the second connecting member 140 .

[0068] In some embodiments, Figure 5 As shown, the outer wall of the first connecting member 130 is provided with a second external thread, and the outer wall of the second connecting member 140 is provided with a third external thread, and the thread rotation direction of the third external thread and the second external thread is opposite, and the component cable structure also includes a cylinder 150, and the inner wall of the cylinder 150 is provided with a second internal thread and a third internal thread at intervals, the second external thread and the second internal thread are threadedly screwed together, and the third external thread and the third internal thread are threadedly screwed together.

[0069] It can be understood that by respectively arranging the second internal thread and the third internal thread at the two end portions of the inner wall of the cylinder 150, so as to respectively screw together with the second external thread arranged on the outer wall of the first connecting member 130 and the third external thread arranged on the outer wall of the second connecting member 140, not only can the detachable connection between the first connecting member 130 and the second connecting member 140 be achieved, but also the relative position between the first connecting member 130 and the second connecting member 140 can be flexibly adjusted according to the length of the cylinder 150 to adapt to different installation requirements.

[0070] In addition, since the second external thread and the third external thread have opposite rotation directions, they can not only provide a certain self-locking property to prevent the connection between the first connecting member 130 and the second connecting member 140 from loosening due to external forces (such as wind), but also absorb certain vibrations to improve the stability of the component cable structure.

[0071] In some embodiments, Figures 1 to 3 , Figure 5 As shown, the chain 120 includes a plurality of first chain pieces 121 and a plurality of first pins 122, and two adjacent first chain pieces 121 are connected by the first pins 122; the first connecting member 130 includes a sleeve 131 and a second pin 132, one end of the sleeve 131 is detachably connected to the second connecting member 140, and the other end of the sleeve 131 is provided with a plurality of second chain pieces 133, and the second chain pieces 133 at least partially extend out of the sleeve 131; the first chain piece 121 at the end is connected to the second chain piece 133 by the second pin 132. It should be noted that the number and shape of the first chain pieces 121 and the second chain pieces 133 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0072] In this embodiment, Figures 1 to 3 , Figure 5 As shown, a portion of the multiple first chain plates 121 are spaced apart along the length direction to form a first chain group, and another portion of the multiple first chain plates 121 are spaced apart along the length direction to form a second chain group. The first chain group and the second chain group are staggered along the width direction and connected by the first pin 122, so that the chain 120 can be turned at multiple locations, the flexibility of the steel strand 110 is achieved, and the load can be effectively distributed to the multiple first chain plates 121 and the first pin 122, thereby reducing the possibility of concentrated stress in the chain 120 and further reducing the manufacturing cost and maintenance cost.

[0073] It can be understood that by making the second chain plate 133 at least partially extend out of the sleeve 131, the second chain plate 133 and the first chain plate 121 at the end of the first chain group are staggered and connected by the second pin 132, so that the first connecting member 130 and the chain 120 are tightly connected while being able to turn at the second pin 132, thereby further realizing the flexibility of turning the steel strand 110.

[0074] The embodiment of the present application also provides a photovoltaic system.

[0075] like Figures 6 to 8 As shown, the photovoltaic system includes a plurality of photovoltaic modules 900 , a photovoltaic support and the above-mentioned module cable structure, the photovoltaic support is used to provide support force for the module cable structure, and the module cable structure is used to provide support force for the photovoltaic modules 900 .

[0076] It can be understood that the photovoltaic support includes two side support beams 210 spaced apart along the width direction thereof and at least one middle support beam 220 , and the middle support beam 220 is disposed between the two side support beams 210 .

[0077] According to the photovoltaic system provided in the embodiment of the present application, by arranging the chain 120 in the component cable structure, the required turning angle of the steel strand 110 can be quickly achieved, and a larger turning angle can be provided. It can also ensure that the steel strand 110 does not need to bear bending stress, so that the steel strand 110 always only bears tensile stress, further ensuring the reliability of the use of the steel strand 110.

[0078] In some embodiments, Figures 6 to 8 As shown, the photovoltaic system further includes a steering structure, which is disposed on the photovoltaic support and abuts against the chain 120 to change the direction, so that the photovoltaic system can adapt to complex terrain environments.

[0079] In some embodiments, Figure 6 As shown, the steering structure includes a limit member 300, and the limit member 300 is provided in at least one of the middle part and the end part of the photovoltaic bracket, and the axial directions of the steel strands 110 connected to the chains 120 respectively abutting against the limit members 300 intersect; wherein, when the limit member 300 is provided in the middle part of the photovoltaic bracket, the two steel strands 110 located on both sides of the limit member 300 respectively support different photovoltaic components 900; when the limit member 300 is provided at the end part of the photovoltaic bracket, the steel strand 110 located on one side of the limit member 300 is used to support the photovoltaic component 900, and the steel strand 110 located on the other side of the limit member 300 is used to connect the anchor 500.

[0080] In this example, Figure 6As shown, each middle supporting beam 220 is provided with two limiting members 300 at intervals along the width direction of the middle supporting beam 220, and the limiting members 300 include a steering shaft 310 and two oppositely arranged folding plates 320, the horizontal portion of the folding plate 320 is installed on the upper surface of the middle supporting beam 220, and the two ends of the steering shaft 310 are respectively passed through the vertical portions of the two folding plates 320, the bottom of the chain 120 abuts against the outer side wall of the steering shaft 310, and the two outer side walls of the chain 120 that are oppositely arranged along the length direction of the middle supporting beam 220 abut against the two surfaces of the two vertical portions that are close to each other, thereby achieving the supporting effect on the chain 120 and limiting the chain 120 along the length direction of the middle supporting beam 220.

[0081] At the same time, compared with the related art in which a curved plate is arranged between two vertical parts to guide and constrain the bending of the steel strand 110, the present embodiment adopts a chain 120 arranged between two vertical parts to replace the part of the steel strand 110 that needs to be bent due to turning. Not only does it not need to use a curved plate, but it can also quickly achieve the required turning angle of the steel strand 110 and ensure that the steel strand 110 does not need to bear bending stress, so that the steel strand 110 always only bears tensile stress, further ensuring the reliability of the use of the steel strand 110.

[0082] In some other embodiments, when the diagonal rod and the steel strand 110 at the end of the photovoltaic bracket are integrated, two limit members 300 are arranged at intervals along the width direction of the side support beam 210, the bottom of the chain 120 abuts against the outer wall of the steering shaft 310, and the two outer walls of the chain 120 that are relatively arranged along the length direction of the side support beam 210 abut against two surfaces close to each other of the two vertical parts, and the steel strand 110 connected to one end of the chain 120 close to the other side support beam 210 is used to support the photovoltaic module 900, and the steel strand 110 connected to one end of the chain 120 away from the other side support beam 210 is fixed to the ground by an anchor 500.

[0083] In some embodiments, Figure 7 and Figure 8 As shown, the steering structure also includes at least two first abutment members 400 disposed at intervals, the first abutment members 400 are installed at one end of the photovoltaic bracket, one of the chains 120 in the component cable structure is respectively wound around the two first abutment members 400, and the axes of the two steel strands 110 respectively connected to the chains 120 are parallel.

[0084] It is understandable that when the side support beam 210 is not provided with a limiting member 300, in order to ensure the reliability and stability of the entire component cable structure, two first abutment members 400 are arranged on one of the side support beams 210 at intervals along the length direction of the side support beam 210, so that the chain 120 located at the corresponding end can be simultaneously wound around the two first abutment members 400, ensuring that the axial directions of the two steel strands 110 connected to the chain 120 are parallel, so that the two steel strands 110 can evenly support the same photovoltaic component 900, and ensuring that the first abutment member 400 provides a stable guiding effect on the chain 120.

[0085] It should be noted that the chain 120 can be simultaneously wound around the two first abutment members 400. Figure 7 The center of curvature formed by the middle chain 120 being bent by the abutment with the two first abutment members 400 is located at a side of the chain 120 close to the other side supporting beam 210 .

[0086] In this embodiment, the first abutment member 400 includes a first rotating shaft and a first baffle, the lower end of the first rotating shaft is passed through the side support beam 210, and the upper end of the first rotating shaft is passed through the first baffle, so that the outer wall of the chain 120 abuts against the outer wall of the first rotating shaft, and the upper surface and lower surface of the chain 120 abut against the lower surface of the first baffle and the upper surface of the side support beam 210 respectively, thereby limiting the chain 120 in the up and down directions and along the length direction of the side support beam 210, and can also reduce the friction generated between the chain 120 and the side support beam 210 when turning, so as to minimize wear.

[0087] In some embodiments, considering the need to ensure that the steel strand 110 is always in tension, the embodiment of the present application provides two solutions when the stopper 300 is only provided on the middle support beam 220. The embodiment of the present application is specifically described below from two different implementation perspectives.

[0088] 1. If Figure 7 As shown, the photovoltaic system further includes two anchors 500 arranged at intervals, the anchors 500 are installed at one end of the photovoltaic support away from the first abutment 400 and connected to the steel strand 110 away from the first abutment 400, and the projection of the component cable structure in the vertical direction is open. The anchors 500 include but are not limited to clip-type anchors.

[0089] It is understandable that two anchors 500 are arranged at intervals along the length direction of the side support beam 210 on which the first abutment member 400 is not installed, and the two anchors 500 are connected to the two steel strands 110 located at the corresponding ends one by one, so that the multiple steel strands 110 are sequentially connected through the chain 120 and can maintain appropriate tension through the pre-tightening force applied by the anchors 500. At the same time, since the projection of the component cable structure in the up and down directions is open, that is, the two steel strands 110 connected to the corresponding anchors 500 are not connected, it is easy to adapt to the situation where the number of photovoltaic components 900 is expanded, which can improve the flexibility of the use of the photovoltaic system.

[0090] 2. If Figure 8 As shown, the steering structure also includes at least two spaced-apart second abutment members 600 and at least one third abutment member 700, the second abutment member 600 is installed at one end of the photovoltaic bracket away from the first abutment member 400, and one of the chains 120 in the component cable structure is respectively wound around the two second abutment member 600 axes; the third abutment member 700 is adjustable in installation position at the end of the photovoltaic bracket to abut and cooperate with the adjacent chain 120, and the projection of the component cable structure in the up and down directions is closed.

[0091] It can be understood that the two second abutment members 600 are arranged at intervals along the length direction of the side support beam 210 on which the first abutment member 400 is not installed, and the chain 120 located at the corresponding end can be simultaneously wound around the two second abutment members 600, and at least one third abutment member 700 is arranged on at least one side support beam 210, so that the multiple steel strands 110 are connected end to end in sequence through the chain 120 and the appropriate tension is maintained by adjusting the installation position of the third abutment member 700 on the corresponding side support beam 210. At the same time, since the projection of the component cable structure in the up and down direction is closed, that is, the two side support beams 210 are respectively provided with chains 120 through the corresponding first abutment members 400 and second abutment members 600, the cost required for setting the anchor 500 can be reduced, and the stability of the entire photovoltaic system structure can be improved as much as possible.

The third abutment member 700 includes a third rotating shaft and a third baffle plate, the lower end of the third rotating shaft is passed through the side supporting beam 210, and the upper end of the third rotating shaft is passed through the third baffle plate, so that the outer wall of the chain 120 abuts against the outer wall of the third rotating shaft, and the upper and lower surfaces of the chain 120 abut against the lower surface of the third baffle plate and the upper surface of the side supporting beam 210 respectively, thereby limiting the chain 120 in the up and down directions and along the length direction of the side supporting beam 210.

[0093] In this embodiment, a third abutment member 700 is provided on each of the two side supporting beams 210, that is, one of the third abutment members 700 is located between the two first abutment members 400, and the other third abutment member 700 is located between the two second abutment members 600, and the third abutment member 700 can slide back and forth on the corresponding side supporting beam 210 along the width direction of the side supporting beam 210, thereby ensuring that the steel strand 110 has tension while reducing the manufacturing cost as much as possible.

[0094] Furthermore, the side support beam 210 is provided with a long hole extending in the width direction of the side support beam 210, and the third abutment member 700 is provided with a mounting hole, and the fixing member passes through the long hole and is threadedly connected to the mounting hole to achieve the adjustable installation position of the third abutment member 700. Of course, in other embodiments, other methods can also be used to achieve the adjustable installation position of the third abutment member 700, and this embodiment does not specifically limit this.
