Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and more specifically, to a flexible photovoltaic bracket system. Background Art

[0002] Flexible photovoltaic bracket is a new type of photovoltaic bracket, which has the characteristics of simple structure, less material use, light weight and large span. Therefore, it can be suitable for crossing unfavorable terrains with large span and high clearance such as mountains, fish ponds and barren slopes, and has great use value for the comprehensive utilization of land.

[0003] At present, the flexible photovoltaic bracket adopts a single-layer double-cable structure. When the single-layer double-cable structure is under wind pressure, the overall downward displacement of the cable system is difficult to control, which makes the overall stability of the flexible photovoltaic bracket poor and the load-bearing capacity low.

[0004] In summary, how to design a flexible photovoltaic support system to control the overall downward displacement of the cable system and improve the overall stability and load-bearing capacity of the flexible photovoltaic support system is a problem that needs to be urgently solved by technical personnel in this field.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0054] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0055] The multiple involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0056] The "parallel" and "perpendicular" involved in this application are "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0057] The flexible photovoltaic support system mainly includes a support and a suspension cable arranged on the support. The suspension cable has prestress to ensure load-bearing capacity.

[0058] In a single-layer cable structure (single-layer double-cable structure), the cables are arranged in the east-west direction, two cables form a group, and the stress stiffness is obtained by tensioning the cable to form a self-balancing system. Under the action of wind pressure, the overall downward displacement of the cable system is difficult to control, and it is easy to produce large deformation, overall instability, and reduced bearing capacity.

[0059] In order to improve the overall stability and load-bearing capacity of a flexible photovoltaic support system, an embodiment of the present application provides a flexible photovoltaic support system.

[0060] The flexible photovoltaic support system provided in the embodiment of the present application includes: a first suspension cable layer and a second suspension cable layer.

[0061] like Figure 1 As shown, the first suspension cable layer includes a first component support cable 1a and a second component support cable 1b. The first component support cable 1a and the second component support cable 1b are used to support the same photovoltaic component, wherein the first component support cable 1a and the second component support cable 1b are both arranged along the first direction, and the first component support cable 1a and the second component support cable 1b are sequentially distributed along the second direction, and any two of the second direction, the first direction and the vertical direction are perpendicular.

[0062] It should be noted that the first component support cable 1a and the second component support cable 1b can both be called component support cable 1. The component support cable 1 is arranged along the first direction, that is, the two ends of the component support cable 1 are distributed in sequence along the first direction, and the middle part of the component support cable 1 can be parallel to the first direction or slightly deviate from the first direction. For example, the middle part of the component support cable 1 deviates from the first direction in the vertical direction.

[0063] The second suspension cable layer includes at least one connecting cable 2, which is arranged along the second direction. It can be understood that the two ends of the connecting cable 2 are distributed in sequence along the second direction, and the middle part of the connecting cable 2 can be parallel to the second direction or slightly deviate from the second direction. For example, the middle part of the connecting cable 2 deviates from the second direction in the vertical direction.

[0064] In the second suspension cable layer, when there are at least two connecting cables 2, any two connecting cables 2 are sequentially distributed along the first direction.

[0065] In some embodiments, the first direction is the east-west direction and the second direction is the north-south direction, so that it is convenient to set up the photovoltaic components and to ensure the power generation of the photovoltaic components. Of course, the first direction and the second direction can be selected as other directions, and the embodiments of the present application are not limited to this.

[0066] The connecting cable 2 is connected to the first component supporting cable 1a and the second component supporting cable 1b through the inter-cable supporting assembly 6.

[0067] As mentioned above, the first component support cable 1a and the second component support cable 1b can both be referred to as component support cables 1. At the connection point between the connecting cable 2 and the component support cable 1, the connecting cable 2 and the component support cable 1 are sequentially distributed in the vertical direction. In order to ensure that the component support cable 1 supports the photovoltaic component, the connecting cable 2 can be selected to be located at the bottom side of the component support cable 1.

[0068] In the above-mentioned flexible photovoltaic support system, the connecting cable 2 is connected to the first component support cable 1a and the second component support cable 1b through the inter-cable support component 6, and the first suspension cable layer is a single-layer suspension cable structure.

[0069] The above-mentioned flexible photovoltaic support system may further include other cable bodies, and all the cable bodies in the flexible photovoltaic support system constitute a suspension cable system. Exemplarily, the suspension cable system includes a first suspension cable layer and a second suspension cable layer.

[0070] In the flexible photovoltaic support system provided in the embodiment of the present application, the connecting cable 2 is connected to the first component support cable 1a and the second component support cable 1b through the inter-cable support assembly. In this way, the first component support cable 1a and the second component support cable 1b increase the stiffness of the connecting cable 2, and the connecting cable 2 increases the stiffness of the first component support cable 1a and the second component support cable 1b. Compared with the single-layer cable structure in the prior art, the stiffness of the entire suspension cable system is increased, the vertical bearing capacity and wind pressure resistance capacity of the suspension cable system are improved, and the overall downward displacement of the suspension cable system is easier to control when wind pressure acts, thereby facilitating the control of the overall downward displacement of the suspension cable system and improving the overall stability and bearing capacity of the flexible photovoltaic support system.

[0071] At the same time, since the stiffness of the entire suspension system is increased, the ability of the suspension system to resist wind uplift is also improved. When the wind lifts, the overall upward displacement of the suspension system is easier to control, thereby facilitating the control of the overall upward displacement of the suspension system and improving the overall stability and bearing capacity of the flexible photovoltaic support system; and, the first suspension layer is a single-layer cable structure with a simpler structure and lower cost, which makes the structure of the entire flexible photovoltaic support system also simpler and the cost lower.

[0072] At the same time, in the flexible photovoltaic support system provided in the embodiment of the present application, since the stiffness of the suspension cable system in the upper and lower directions is increased, the cable diameter (diameter) of the component support cable 1 and the connecting cable 2 can be reduced, which can reduce the cable body cost.

[0073] In the embodiment of the present application, the first component support cable 1a and the second component support cable 1b form a component support cable group, and there is at least one component support cable group. When there are at least two component support cable groups, any two component support cable groups are distributed in sequence along the second direction.

[0074] The heights of the first component support cable 1a and the second component support cable 1b in the component support cable group can be the same or different. In order to realize the tilted setting of the photovoltaic component, the heights of the first component support cable 1a and the second component support cable 1b are different. For example, the first component support cable 1a is lower than the second component support cable 1b.

[0075] As mentioned above, the first component support cable 1a and the second component support cable 1b can both be referred to as component support cables 1, the two ends of the component support cable 1 are respectively fixed to the two first end support components 3, and the middle of the component support cable 1 is fixed to the middle support component 5, that is, the middle support component 5 is located between the two first end support components 3. In the case where the component support cable 1 is shorter, the middle support component 5 may not be provided, that is, the middle of the component support cable 1 is not fixed.

[0076] It should be noted that the middle portion of the component support cable 1 can be understood as: the middle portion of the component support cable 1 in the length direction, that is, the portion excluding the two ends of the component support cable 1 in the length direction.

[0077] In some embodiments, the first component support cable 1a and the second component support cable 1b in the component support cable group share the first end support component 3, and the first component support cable 1a and the second component support cable 1b of different component support cable groups are fixed to different first end support components 3. In some other embodiments, at least two component support cable groups may share the first end support component 3.

[0078] In the embodiment of the present application, the middle support assembly 5 is arranged along the second direction, so that the middle support assembly 5 is convenient for connecting the assembly support cable group. In the second direction, there can be one or more than two middle support assemblies 5. In the case where there is one middle support assembly 5 in the second direction, the middle support assembly 5 connects all the assembly support cable groups; in the case where there are more than two middle support assemblies 5 in the second direction, at least one middle support assembly 5 connects at least two assembly support cable groups, and / or at least one middle support assembly 5 connects one assembly support cable group.

[0079] In the embodiment of the present application, the first end support assembly 3 and the middle support assembly 5 can be understood as a structure of a suspension cable support assembly. In the second direction, the suspension cable support assemblies are distributed in rows. It can be understood that any two suspension cable support assemblies in each row are distributed in sequence along the second direction; or, there is one suspension cable support assembly in each row, and the length direction of the suspension cable support assembly in each row is the second direction. The suspension cable support assembly is a plurality of rows (at least two rows), and any two rows of suspension cable support assemblies are distributed in sequence along the first direction.

[0080] As mentioned above, the first end support assembly 3 and the middle support assembly 5 can be understood as a structure of a suspension support assembly, so there are at least three suspension support assemblies used to install the same component support cable 1, of which two suspension support assemblies are the first end support assemblies 3, and at least one suspension support assembly is the middle support assembly 5.

[0081] The distribution of the middle support assembly 5 and the inter-cable support assembly 6 is selected according to actual conditions.

[0082] like Figure 1 and Figure 2 As shown, in some embodiments, in the first direction, the middle support assembly 5 and the inter-cable support assembly 6 are distributed alternately, and the middle support assembly 5 is distributed between two adjacent inter-cable support assemblies 6 .

[0083] like Figure 3As shown, in some embodiments, in the first direction, a portion of the inter-cable support components 6 are distributed on one side of the middle support component 5 , and another portion of the inter-cable support components 6 are distributed on the other side of the middle support component 5 .

[0084] In some other embodiments, the middle support assembly 5 and the inter-cable support assembly 6 may also be distributed in other ways, which is not limited in the embodiments of the present application.

[0085] In the embodiment of the present application, at least one connecting cable 2 forms a connecting cable group, and the connecting cable group may be one or more than two. When there are more than two connecting cable groups, any two connecting cable groups are distributed in sequence along the first direction.

[0086] In the embodiment of the present application, both ends of the connecting cable 2 are fixed to the second end support assembly 4. In the case where the connecting cable group includes at least two connecting cables 2, any two connecting cables 2 in the connecting cable group are distributed in sequence along the first direction.

[0087] In order to simplify the structure, the connecting cable group may be selected to include one connecting cable 2 or two connecting cables 2 .

[0088] For ease of installation, any two connecting cables 2 in the connecting cable group can be selected to share the second end support assembly 4, and any two connecting cable groups can be fixed to different second end support assemblies 4. Of course, other corresponding relationships between the connecting cable group and the second end support assembly 4 can also be selected, and are not limited to the above structure.

[0089] In the embodiment of the present application, each connecting cable group is connected to all the component support cable groups through a row of inter-cable support components 6, and the inter-cable support components and the component support cable groups in each row of inter-cable support components correspond one to one.

[0090] It should be noted that in the second direction, the suspension support components 6 are distributed in rows, the number of rows of the suspension support components 6 is the same as the number of the connecting cable groups, and the rows formed by the suspension support components 6 correspond to the connecting cable groups one by one.

[0091] As described above, in the first direction, the middle support components 5 and the inter-cable support components 6 are distributed alternately, and the middle support components 5 are distributed between two adjacent inter-cable support components 6. In this case, the middle support components 5 are at least one row, the inter-cable support components 6 are at least two rows, and the connecting cable groups are at least two. Figure 1 and Figure 2 As shown, there are four connecting cable groups, four rows of inter-cable support components 6, and three rows of middle support components 5.

[0092] As described above, in the first direction, a portion of the inter-cable support components 6 are distributed on one side of the middle support component 5, and another portion of the inter-cable support components 6 are distributed on the other side of the middle support component 5. In this case, the inter-cable support components 6 are at least two rows, the middle support component 5 can be one row, and the number of connecting cable groups is at least two. Figure 3-Figure 5 As shown, there are four rows of inter-cable support assemblies 6, one row of middle support assemblies 5, and four connecting cable groups.

[0093] In some embodiments, when the component support cable 1 is fixed to the suspension cable support assembly, the flexible photovoltaic support system also includes an anti-wind cable assembly 7. Among them, at least one anti-wind cable assembly 7 connects two inter-cable support assemblies 6 adjacent in the first direction; and / or, at least one anti-wind cable assembly 7 connects the inter-cable support assembly 6 and the suspension cable support assembly adjacent in the first direction. In this way, the anti-wind cable assembly 7 plays a role in stabilizing the component support cable 1 and the connecting cable 2, and can control the disturbance of the connecting cable 2 and the component support cable 1, so as to reduce the deflection of the entire suspension cable system, thereby reducing the overall upward trend force and the overall downward trend force of the suspension cable system, and effectively improving the overall stability and bearing capacity of the flexible photovoltaic support system.

[0094] The above structure is particularly suitable for situations where the wind pressure is large and / or the span is large. A large span means that the span of the connecting cable 2 is large, and / or the distance between the column where the inter-cable support assembly 6 is located and the column where the adjacent suspension cable support assembly is located is large. In the case of small wind pressure and / or small span, the flexible photovoltaic support system may not be provided with the wind-resistant cable assembly 7.

[0095] In the embodiment of the present application, the number and distribution of the anti-wind cable components 7 are selected according to actual conditions.

[0096] like Figure 1 and Figure 2 As shown, in some embodiments, there are four connecting cable groups, four rows of inter-cable support assemblies 6, two first end support assemblies 3, and three rows of middle support assemblies 5, and the inter-cable support assemblies 6 and the middle support assemblies 5 in each row are alternately distributed. There are eight wind-resistant cable assemblies 7, two wind-resistant cable assemblies 7 are connected to the inter-cable support assemblies 6 and the first end support assemblies 3 adjacent in the first direction, and six wind-resistant cable assemblies 7 are connected to the inter-cable support assemblies 6 and the middle support assemblies 5 adjacent in the first direction.

[0097] like Figure 3As shown, in some embodiments, there are four connecting cable groups, four rows of inter-cable support assemblies 6, two first end support assemblies 3, one row of middle support assemblies 5, two inter-cable support assemblies 6 are located on one side of the middle support assembly 5, and the other two rows of inter-cable support assemblies 6 are located on the other side of the middle support assembly 5. There are six wind-resistant cable assemblies 7, two wind-resistant cable assemblies 7 are connected to the inter-cable support assemblies 6 and the first end support assemblies 3 adjacent in the first direction, two wind-resistant cable assemblies 7 are connected to the inter-cable support assemblies 6 and the middle support assembly 5 adjacent in the first direction, and two wind-resistant cable assemblies 7 are connected to two inter-cable support assemblies 6 adjacent in the first direction.

[0098] Figure 1-Figure 3 In the structure shown in FIG. 1 , the number of connecting cable groups, the number of columns of the cable support components 6, and the number of columns of the middle support components 5 can be adjusted according to actual conditions, and the number of wind-resistant cable components 7 can also be adjusted, and is not limited to Figure 1-Figure 3 The structure shown.

[0099] In actual situations, the anti-wind cable components 7 may also be distributed in other ways, and are not limited to the above embodiments.

[0100] In the above-mentioned flexible photovoltaic support system, the deformation of the middle position of the suspension cable system in the second direction is relatively large. In order to effectively control the upward and downward displacement of the suspension cable system as a whole, in some embodiments, among the inter-cable support assembly 6 and the suspension cable support assembly connected to the wind-resistant cable assembly 7, the inter-cable support assembly 6 is located in the middle of the connecting cable 2, and the suspension cable support assembly deviates from the inter-cable support assembly 6 in the second direction, that is, the suspension cable support assembly is closer to the end of the connecting cable 2 than the inter-cable support assembly 6. In this way, the force applied to the middle position in the second direction can be effectively shared to the two end positions in the second direction, thereby improving the wind-resistant effect of the wind-resistant cable assembly 7.

[0101] It should be noted that the middle portion of the connecting cable 2 refers to the middle portion of the connecting cable 2 in the length direction.

[0102] In actual situations, the inter-cable support assembly 6 and the suspension cable support assembly connected to the wind-resistant cable assembly 7 may also be selected to be distributed at other positions in the second direction, and are not limited to the above embodiments.

[0103] Accordingly, in order to effectively control the upward and downward displacement of the entire suspension cable system, one of the two inter-cable support components 6 connected to the wind-resistant cable component 7 can be selected to deviate from the other in the second direction, and the other is located in the middle of the connecting cable 2, that is, one is closer to the end of the connecting cable 2 than the other. In this way, the force applied to the middle position in the second direction can be effectively shared to the two end positions in the second direction, thereby improving the wind-resistant effect of the wind-resistant cable component 7.

[0104] In actual situations, the two inter-cable support assemblies 6 connected to the wind-resistant cable assembly 7 may also be selected to be distributed at other positions in the second direction, and are not limited to the above embodiment.

[0105] In the embodiment of the present application, the wind-resistant cable assembly 7 includes a first wind-resistant cable 71 and a second wind-resistant cable 72; wherein, the first ends of the first wind-resistant cable 71 and the second wind-resistant cable 72 are both connected to the inter-cable support assembly 6, and the second ends of the first wind-resistant cable 71 and the second wind-resistant cable 72 are both connected to the suspension cable support assembly or another inter-cable support assembly 6.

[0106] In order to improve the wind-resistant effect of the wind-resistant cable assembly 7, the distance between the first end of the first wind-resistant cable 71 and the first end of the second wind-resistant cable 72 can be selected to be smaller than the distance between the second end of the first wind-resistant cable 71 and the second end of the second wind-resistant cable 72. In this way, the larger force at the position where the suspension system is subjected to a larger force can be divided into two parts, and the two parts of the force are transferred to the position where the suspension system is subjected to a smaller force, thereby improving the wind-resistant effect of the wind-resistant cable assembly 7.

[0107] When the suspension cable system is subjected to greater force in the middle part in the second direction, the first ends of the first wind-resistant cable 71 and the second wind-resistant cable 72 are both located in the middle part of the connecting cable 2, the first ends of the first wind-resistant cable 71 and the second wind-resistant cable 72 are both connected to the inter-cable support assembly 6 in the middle part of the connecting cable 2, and the second ends of the first wind-resistant cable 71 and the second ends of the second wind-resistant cable 72 are respectively close to the two ends of the connecting cable 2.

[0108] In the above-mentioned wind-resistant cable assembly 7, the first wind-resistant cable 71 and the second wind-resistant cable 72 can be arranged axially symmetrically, and the axis of symmetry is parallel to the first direction. In this way, the force uniformity of the suspension cable system is improved.

[0109] Of course, the first anti-wind rope 71 and the second anti-wind rope 72 may be distributed in other ways. For example, the first anti-wind rope 71 and the second anti-wind rope 72 are distributed in an eight-shaped shape.

[0110] In the wind-resistant cable assembly 7, the first wind-resistant cable 71 and the second wind-resistant cable 72 can be arranged at the same height or at different heights, depending on the actual situation. In order to improve the force uniformity of the suspension cable system, the first wind-resistant cable 71 and the second wind-resistant cable 72 can be arranged at the same height.

[0111] In the wind-resistant cable assembly 7, the two ends of the first wind-resistant cable 71 can be set at the same height or at different heights, and the two ends of the second wind-resistant cable 72 can also be set at the same height or at different heights, depending on the actual situation, and this embodiment does not limit this.

[0112] In the embodiment of the present application, the structures of the cable support components 6 of at least two columns in the flexible photovoltaic support system can be selected to be the same, and / or the structures of the cable support components 6 of at least two columns in the flexible photovoltaic support system can be selected to be different.

[0113] In order to simplify the structure, the structure of the inter-cable support components 6 of all columns in the flexible photovoltaic support system can be selected to be the same.

[0114] like Figure 4 As shown, in order to meet certain requirements, the structures of the cable support components 6 of at least two columns in the flexible photovoltaic support system can be selected to be different.

[0115] The specific structure of the inter-cable support assembly 6 is selected according to actual conditions.

[0116] The structure of the inter-cable support assembly 6 is described below based on a specific suspension cable system.

[0117] As mentioned above, the first component support cable 1a and the second component support cable 1b form a component support cable group, at least one connecting cable 2 forms a connecting cable group, each connecting cable group is connected to all component support cable groups through a row of inter-cable support components 6, and the inter-cable support components 6 in each row of inter-cable support components 6 correspond to the component support cable group. Among them, the first component support cable 1a and the second component support cable 1b are both component support cables 1. Based on this, Figure 5 and Figure 6 As shown, the inter-cable support assembly 6 includes a first component 61 and a second component 62 .

[0118] The first component 61 connects the first component support cable 1a and the second component support cable 1b, and the first component 61 corresponds to the connecting cable 2. There are two first components 61, and the two first components 61 are distributed in parallel.

[0119] like Figure 5 As shown, the connecting cable 2 is directly connected to the connection between the first component support cable 1a and the first component 61, and the second component 62 connects the second component support cable 1b and the connecting cable 2. The second component 62 and the connecting cable 2 correspond to each other one by one. The first component 61 and the second component 62 corresponding to the same connecting cable 2 are connected to the same position of the second component support cable 1b. Or, as Figure 6 As shown, the second component 62 connects the component support cable 1 and the connecting cable 2, the two second components 62 correspond to the same connecting cable 2, and the first component 61 and the second component 62 corresponding to the same connecting cable 2 are connected to the same position of the component support cable 1.

[0120] In order to facilitate installation, the length direction of the second component 62 may be selected to be parallel to the vertical direction, that is, the second component 62 is arranged along the vertical direction.

[0121] It should be noted that Figure 6In the connecting cable group, there are two connecting cables 2, and there are four second components 62 in the inter-cable support assembly 6, one second component 62 connects the first component support cable 1a and a connecting cable 2, one second component 62 connects the first component support cable 1a and another connecting cable 2, one second component 62 connects the second component support cable 1b and a connecting cable 2, and one second component 62 connects the second component support cable 1b and another connecting cable 2, and the first component 61 and the second component 62 corresponding to the same connecting cable 2 are connected to the same position of the first component support cable 1a and the same position of the second component support cable 1b.

[0123] The above-mentioned inter-cable support assembly 6 can be applicable to the case where the connecting cable group includes one connecting cable 2, and can also be applicable to the case where the connecting cable group includes at least two connecting cables 2.

For ease of installation, the third member 63 can be selected to be arranged along the first direction, that is, the length direction of the third member 63 is parallel to the first direction. The third member 63 corresponds to the component support cable 1 in the component support cable group.

[0126] In the inter-cable support assembly 6, of the two second members 62 located at the edge in the first direction, the connection between one and the assembly support cable 1 and the connection between the other and the connection cable 2 are connected by a fourth member 64. Figure 6 In the structure shown, there are two fourth components 64. To simplify installation, the two fourth components 64 can be arranged in parallel.

[0127] like Figure 6 As shown, in the inter-cable support assembly 6, there are two second members 62 in the second direction, one of which is connected to the assembly support cable 1 and the other is connected to the connection cable 2 through a fifth member 65. Figure 6 In the structure shown, there are two fifth components 65. To simplify installation, the two fifth components 65 can be arranged in parallel.

[0128] In order to improve the connection stability of the inter-cable support assembly 6 , when the inter-cable support assembly 6 includes a third member 63 and a fourth member 64 , the fourth member 64 can be selected to be connected to the connection between the third member 63 and the second member 62 .

[0129] In order to improve the connection stability of the inter-cable support assembly 6, when the inter-cable support assembly 6 includes a third component 63, a fourth component 64 and a fifth component 65, the fifth component 65, the first component 61 and the second component 62 are connected to the same position of the second component support cable 1b, and the fifth component 65, the second component 62, the third component 63, and the fourth component 64 are connected to the same position of a connecting cable 2.

[0132] The cable support assembly 6 can also be other structures, such as Figure 5 and Figure 6 Components may be added or removed from the structure shown, and this embodiment does not limit this.

The inter-cable support assembly 6 includes a relatively inclined sixth member 66 and a seventh member 67. It can be understood that the sixth member 66 and the seventh member 67 are arranged in different planes.

[0134] In the above structure, the first component support cable 1a and the first connecting cable 2a are connected to one end of the sixth component 66, and the second component support cable 1b and the second connecting cable 2b are connected to the other end of the sixth component 66; the first component support cable 1a and the second connecting cable 2b are connected to one end of the seventh component 67, and the second component support cable 1b and the first connecting cable 2a are connected to the other end of the seventh component 67.
