Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a steel strand positioning structure and a flexible photovoltaic support. Background Technology

[0002] Currently, most fixed supports on the market are flexible and secured with bolts. Flexible tracking supports are newer products and are prone to underload during rotation. The steel strands, being flexible materials, are susceptible to displacement when rotating due to construction errors or the influence of inclined beams. Existing connecting fasteners are fixed to stationary steel cable anchors, creating relative movement between the moving steel strands and the fixed fasteners, resulting in friction. This friction can easily wear down the protective layer of the steel strands, leading to breakage. Utility Model Content

[0003] The purpose of this utility model is to provide a steel strand positioning structure and a flexible photovoltaic support, which can not only accommodate the displacement of the steel strand caused by construction errors during rotation, but also protect the coating of the steel strand and avoid breakage caused by friction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a steel strand positioning structure for limiting the steel strand of a flexible photovoltaic bracket, wherein the steel strand extends along a first direction, and includes: a fixed seat for supporting the steel strand; a moving mechanism disposed on the fixed seat and capable of moving relative to the fixed seat in the first direction; and a cable fixing member for fixing the steel strand to the moving mechanism in a non-sliding manner.

[0005] As a further improvement of the present invention, the invention also includes a limiting member, which is disposed at at least one end of the moving mechanism in the moving direction to limit the cable fixing member.

[0006] As a further improvement of this utility model, the invention also includes a guiding mechanism, through which the moving mechanism moves along the first direction.

[0007] As a further improvement of the present invention, the guiding mechanism includes a guiding part, and the moving mechanism includes a mating part that matches the guiding part. The guiding part includes one of a slide rail, a guide rail, a groove, an elongated hole, a bolt, a pin, and a screw. The mating part includes one of a slider, a roller, a positioning block, and a through hole.

[0008] As a further improvement of the present invention, the fixed base is provided with a receiving cavity, the moving mechanism is a base located in the receiving cavity and moving at an upper limit in the first direction, the base is fixedly connected to the cable fixing member, the guide portion passes through the fixed base and the base along the first direction, and the width of the base along the first direction is smaller than the width of the receiving cavity along the first direction.

[0009] As a further improvement of the present invention, the fixing base includes a first outer wall and a second outer wall that are disposed opposite to each other in the first direction and extend parallel to each other in the second direction. The first direction is perpendicular to the second direction. The receiving cavity is provided between the first outer wall and the second outer wall. The base includes a top wall, a first inner wall and a second inner wall. The top wall is integrally connected to the first inner wall and the second inner wall. The first inner wall is parallel to the first outer wall and is disposed on the inner side of the first outer wall. The second inner wall is parallel to the second outer wall and is disposed on the inner side of the second outer wall. The first inner wall and the second inner wall are used to connect to the fixing base. The cable fixing member is fixed to the top wall.

[0010] As a further improvement of the present invention, the first outer wall, the first inner wall, the second inner wall and the second outer wall are respectively provided with through holes, the guide mechanism is provided through the corresponding through holes on the first outer wall, the first inner wall, the second inner wall and the second outer wall along the first direction, and the limiting member is located at at least one end of the guide mechanism.

[0011] As a further improvement of the present invention, the guide part is a bolt, the mating part is a through hole provided on the base that allows the bolt to pass through, and the limiting member is the first outer wall and the second outer wall.

[0012] As a further improvement of this utility model, a bayonet is formed at the top of both the first outer wall and the top of the second outer wall, and the bayonet is used to limit the steel strand.

[0013] To achieve the above objectives, the present invention adopts the following technical solution two: a flexible photovoltaic support, which includes a column, steel strands and a steel strand positioning structure as described above, wherein the steel strands extend along a third direction, the column extends along a second direction, the first direction is perpendicular to the third direction, and the fixing seat of the steel strand positioning structure is disposed at one end of the column.

[0014] Compared to existing technologies, this utility model, by setting up a fixed base, a moving mechanism, and a cable fixing component, allows the moving mechanism to move relative to the fixed base in the first direction of the steel strand's extension. In other words, the displacement of the steel strand caused by construction errors or rotation under the influence of the inclined beam is transferred to the cable fixing component and then to the moving mechanism. That is, the cable fixing component and the moving mechanism move as a whole relative to the fixed base, and there is no relative displacement between the steel strand and the cable fixing component. Therefore, there is no friction, and the protective layer on the outside of the steel strand will not be worn, thus preventing the steel strand from breaking. Attached Figure Description

[0023] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "front," "back," "left," "right," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" covers the element following "comprising" or "including" and its equivalents, which does not exclude that the element preceding "comprising" or "including" may also include other elements. If "several" appears in this utility model, it means two or more.

[0026] Please refer to Figures 1 to 8 As shown, this utility model discloses a steel strand positioning structure 100 for fixing a steel strand 300, the steel strand 300 extending along a first direction. The steel strand positioning structure 100 includes: a fixing base 1, a cable fixing member 2, and a moving mechanism. The fixing base 1 supports the steel strand 300. The moving mechanism is at least partially disposed on the fixing base 1 and is movable relative to the fixing base 1 in the first direction. The cable fixing member 2 is used to fix the steel strand 300 to the moving mechanism in a non-sliding manner. The cable fixing member 2 has a cavity for accommodating the steel strand 300, the cavity for fixing the steel strand 300 to the cable fixing member 2, such that the steel strand 300 cannot move relative to the cable fixing member 2 within the cavity. With this configuration, when the steel strand 300 is displaced due to the rotation of the support, the cable fixing member 2 moves relative to the fixing seat 1. There will be no relative displacement between the steel strand 300 and the cable fixing member 2. Therefore, there will be no friction between the steel strand 300 and the cable fixing member 2, and the steel strand 300 will not break due to wear of the outer protective layer.

[0027] Furthermore, please Figure 4 , Figure 7 and Figure 8 The steel strand positioning structure 100 also includes a limiting member, which is located at at least one end of the moving mechanism in the moving direction to limit the cable fixing member 2 for stopping and preventing slippage.

[0028] Furthermore, this utility model also includes a guiding mechanism, through which the moving mechanism moves along a first direction.

[0029] Please refer to Figure 4 , Figure 7 and Figure 8 As shown, the fixing base 1 is preferably a flexible photovoltaic bracket's inclined beam 200, a structural member fixedly connected to the inclined beam 200, or a mounting base located at the top of the column 400. In this embodiment, the fixing base 1 is fixedly connected to the inclined beam 200, and the fixing base 1 includes a first outer wall 11 and a second outer wall 12 that are disposed opposite each other in a first direction and extend parallel to each other in a second direction. The first direction specifically refers to... Figure 1 The left and right directions in the middle, the second direction specifically refers to Figure 1 The front and rear directions within the structure. This utility model also has a third direction extending from the column 400, the third direction being... Figure 1 The vertical direction is defined. Therefore, the first direction is perpendicular to the second and third directions. A receiving cavity 10 is provided between the first outer wall 11 and the second outer wall 12. In a specific embodiment, the fixing base 1 also includes a third wall 13 and a fourth wall 14 that are arranged opposite each other in the second direction and extend parallel to each other in the first direction. That is, the first outer wall 11 and the second outer wall 12 are connected as a whole by the third wall 13 and the fourth wall 14. Therefore, in a specific embodiment, the receiving cavity 10 is formed by the first outer wall 11, the second outer wall 12, the third wall 13 and the fourth wall 14. In another embodiment (not shown), the third wall 13 and the fourth wall 14 may not be provided. Instead, a bottom wall may be provided, and the first outer wall 11 and the second outer wall 12 may be connected as a whole by the bottom wall. Even in another embodiment (not shown), the first outer wall 11 and the second outer wall 12 may not be connected as a whole. Instead, they may be independently welded to the inclined beam 200 before the receiving cavity 10 is formed. In another embodiment, the fixed base 1 can also be an inclined beam 200, with the moving mechanism mounted on the inclined beam 200 and the cable fixing member 2 mounted on the moving mechanism; in yet another embodiment, the flexible photovoltaic support does not have an inclined beam 200, but instead directly mounts the steel strand 300 on the top of the column, and the fixed base 1 can also be a mounting base mounted on the top of the flexible photovoltaic support column, as long as it can support the cable fixing member 2 and the steel strand 300, there are no restrictions here.

[0030] Please refer to Figure 5 , Figure 7 and Figure 8As shown, the moving mechanism includes a base 21 located within the receiving cavity 10 and movable to its upper limit in a first direction. The cable fixing member 2 includes a locking member 22 through which a steel strand 300 passes. The locking member 22 is fixedly connected to the base 21. The width of the base 21 along the first direction is less than the width of the receiving cavity 10 along the first direction. In a specific embodiment, the fixed connection between the locking member 22 and the base 21 can be achieved by integral molding or detachable fixed connection. That is, whether the locking member 22 and the base 21 are integrally molded or detachably fixedly connected, the locking member 22 and the base 21 are a movable whole. The width of the base 21 along the first direction is less than the width of the receiving cavity 10 along the first direction, that is, there is a certain distance between the first inner wall 211 and the second inner wall 212 of the base 21 and the corresponding first outer wall 11 and the second outer wall 12, respectively, thereby providing space for the base 21 to move within the receiving cavity 10. The moving mechanism and cable fixing member 2 are only allowed to move to their upper limit in the first direction, that is, the moving direction of the moving mechanism and cable fixing member 2 is consistent with the extension direction of the steel strand 300, i.e., the left and right direction. With this setting, the displacement of the steel strand 300 caused by construction errors or rotation driven by the inclined beam 200 will be transferred to the cable fixing member 2. In other words, the moving mechanism and cable fixing member 2 move relative to the fixed seat 1. There is no relative displacement between the steel strand 300 and the entire moving mechanism and cable fixing member 2. There is no friction between the steel strand 300 and the locking member 22 of the cable fixing member 2, so the protective layer on the outside of the steel strand 300 will not be worn, which would lead to the breakage of the steel strand 300.

[0031] Please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the base 21 is a U-shaped plate, which includes a top wall 210, a first inner wall 211, and a second inner wall 212. The top wall 210 is integrally connected to the first inner wall 211 and the second inner wall 212. The first inner wall 211 is parallel to the first outer wall 11 and is located inside the first outer wall 11. The second inner wall 212 is parallel to the second outer wall 12 and is located inside the second outer wall 12. The first inner wall 211 and the second inner wall 212 are used to connect to the fixed base 1, and the locking member 22 is fixed to the top wall 210. That is, the locking member 22 is fixedly installed as a whole with the base 21, and the entire cable fixing member 2 is then assembled onto the fixed base 1, thereby ensuring that the cable fixing member 2 is integrally movable within the receiving cavity 10 of the fixed base 1.

[0032] It should also be noted that, please refer to Figure 7 and Figure 8When the first inner wall 211 is fitted to the inner side of the first outer wall 11, there is a gap between the second inner wall 212 and the second outer wall 12; when the second inner wall 212 is fitted to the inner side of the second outer wall 12, there is also a gap between the first inner wall 211 and the first outer wall 11. This arrangement is to provide movable space so that the base 21 can be limited to move along a first direction between the first outer wall 11 and the second outer wall 12.

[0033] Please refer to Figure 5 As shown, the locking member 22 includes a U-shaped rod, which includes a curved top 220 and two straight legs 221 extending in the same direction from the curved top 220. The top wall 210 is provided with through holes 2100, and the two straight legs 221 pass through the two through holes 2100 respectively. This design of the locking member 22 mainly utilizes the shape of the inner bottom curved surface of the curved top 220 to match the shape of the steel strand 300, thereby fixing the steel strand 300. The two straight legs 221 serve to fix the locking member 22 to the base 21 for positioning.

[0034] Please continue to refer to Figure 5 As shown, the locking element 22 also includes a second nut 222 located below the top wall 210 and having internal threads. The two straight legs 221 have external threads, and the second nut 222 is screwed onto the two straight legs 221 and abuts against the side of the top wall 210 facing away from the curved top 220. This secures the locking element 22 to the base 21, achieving both positioning and locking, preventing it from easily coming loose upwards.

[0035] Please refer to Figure 4 and Figure 5As shown, the locking member 22 also includes a pad 223. The pad 223 is located on the top wall 210 and has a curved surface 2230 facing the curved top 220. The curved top 220 and the curved surface 2230 cooperate to form a cavity through which the steel strand 300 passes. The function of the pad 223 is to form a curved surface shape that is symmetrical to the inner bottom curved surface of the curved top 220 of the locking member 22, that is, two upper and lower C-shapes combined to form an O-shape, which fits perfectly to fix the outer surface of the steel strand 300, thus providing a positioning function. In other words, there is no relative displacement between the steel strand 300 and the entire cable fixing member 2, specifically the locking member 22. Therefore, there is no friction between the steel strand 300 and the locking member 22, which have no relative displacement. In a specific embodiment, the pad 223 also has through holes at both ends of its curved shape, and the two straight legs 221 pass through the through holes of the pad 223 accordingly. Therefore, the pad 223 is also locked on the base 21 and will not move, ensuring stability. In other embodiments not shown, the cable fixing member 2 can also be achieved by eliminating the pad 223 and directly fixing the U-shaped rod to the base 21 with a nut, or by using other existing cable clamp structures disclosed in patents CN222262549U, CN221647515U, and CN219345384U. There are no restrictions here, as long as the steel strand 300 can be firmly confined in the cavity of the cable fixing member 2, and the steel strand 300 is fixed relative to the cable fixing member 2 and cannot move relative to the cable fixing member 2 in the cavity, it is within the protection scope of this utility model.

[0036] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the first outer wall 11, the first inner wall 211, the second inner wall 212, and the second outer wall 12 are respectively provided with through holes 1200. The guide mechanism passes through the corresponding through holes 1200 on the first outer wall 11, the first inner wall 211, the second inner wall 212, and the second outer wall 12 along the first direction. Further, in a preferred embodiment, the diameter of the through hole 1200 is slightly larger than the diameter of the guide mechanism, and there is a gap between the two ends of the base 21 along the second direction and the corresponding third wall 13 or fourth wall 14, thereby further accommodating the displacement of the steel strand 300 and avoiding wear of the steel strand 300.

[0037] It is understood that the moving mechanism moves under the guidance of the guiding mechanism, which includes a guiding part and a mating part that matches the guiding part. The guiding part and the mating part can be implemented in various ways:

[0038] Implementation Method 1: The guide part and the mating part are a slider-rail mating mechanism. The guide part includes a slide rail that extends along a first direction on the fixed base 1, and the mating part includes a slider that is provided on the moving mechanism. The cable fixing member 2 fixes the steel strand 300 to the moving mechanism in a non-sliding manner. Driven by the steel strand 300, the slider moves relative to the slide rail, thereby realizing the relative movement of the cable fixing member 2 on the fixed base 1. It can be understood that in its alternative implementation, the guide part includes a slider, and the mating part includes a slide rail that mates with the slider.

[0039] Implementation Method 2: The guide part and the mating part are roller guide rail mating mechanisms. The guide part includes a guide rail provided on the fixed base 1, which extends along a first direction. The mating part includes a roller provided on the moving mechanism. Driven by the steel strand 300, the roller moves on the guide rail, thereby realizing the relative movement of the cable fixing member 2 on the fixed base 1. Similarly, in its alternative implementation, the guide part includes a roller, and the mating part includes a guide rail that mates with the roller.

[0040] Implementation Method 3: The guide part and the mating part are a structure in which an elongated hole and a positioning block are mated. The guide part includes an elongated hole opened on the fixed base 1, which extends along a first direction. The mating part includes a positioning block provided at the bottom of the moving mechanism. The positioning block extends into the elongated hole and can move in the elongated hole. The elongated hole is preferably a waist-shaped hole or a rectangular hole. The positioning block is preferably cylindrical, square, T-shaped, etc., as long as it can fit the elongated hole. Similarly, in its alternative implementation, the guide part includes a positioning block, and the mating part includes an elongated hole that mates with the positioning block.

[0041] Implementation Method 4: The guide part and the mating part are groove and positioning block mating structures. The guide part includes a groove opened on the fixed base 1, and the mating part includes a positioning block provided at the bottom of the moving mechanism. The positioning block moves in the groove. The groove is preferably arc-shaped, T-shaped, I-shaped, trapezoidal, etc., and the shape of the positioning block is adapted to the groove. Similarly, in its alternative implementation, the guide part includes a positioning block, and the mating part includes a groove that mates with the positioning block.

[0042] Implementation Method 5: As in this embodiment Figure 4 As shown, the guiding mechanism includes a pin, screw, or bolt 31, and the mating part includes a through hole 1200 that allows the pin, screw, or bolt 31 to pass through. The pin, screw, or bolt 31 passes through the through hole 1200 on the fixed seat 1 and the base 21, and can also play a guiding role.

[0043] It should be noted that the moving mechanism can be in the form of a bent sheet metal, such as... Figure 4The structure shown can also be a strip, block, or other hollow or solid structure set above the fixed seat 1; it can be a single component or an assembly formed by combining multiple components. The specific structural form of the moving mechanism is not limited. As long as it can achieve a fixed connection with the cable fixing member 2 and can move relative to the fixed seat 1 in the first direction, it is within the protection scope of this utility model.

[0044] The movement of the moving mechanism in the first direction is also limited by a limiting member. The limiting member is located at at least one end of the moving mechanism in the direction of movement to limit the range of motion of the cable fixing member 2 and the moving mechanism. Correspondingly, the limiting member is preferably implemented by providing a limiting boss, a limiting post, a limiting baffle, a limiting wall, making the groove or elongated hole non-through, or using the side wall forming the groove or elongated hole along its length as a limiting member, etc. Anything that can limit the movement of the cable fixing member 2 in the first direction is acceptable and falls within the protection scope of this utility model. Please refer to... Figures 1 to 8 As shown in the specific embodiment, the guiding mechanism includes a bolt 31 with a stop head 30. The stop head 30 is located at one end of the bolt 31, and a nut 32 that mates with the bolt 31 is located at the other end. The nut 32 and the stop head 30 are located at opposite ends of the bolt 31 along a first direction, thus limiting the movement of the bolt 31. The limiting elements are the first outer wall 11 and the second outer wall 12, which restrict the movement range of the base 21 along the bolt 31. Preferably, the bolt 31 is a semi-threaded bolt, with the unthreaded portion located within the receiving cavity 10, and the threaded portion mates with the nut 32 to limit the movement of the bolt 31. It is easily understood that the nut 32 is screwed onto the free end of the bolt 31 away from the stop head 30, and the stop head 30 of the bolt 31 and the nut 32 abut against the first outer wall 11 and the second outer wall 12, respectively. One end of the bolt 31 passes through the through holes 1200 of the first outer wall 11, the first inner wall 211, the second inner wall 212, and the second outer wall 12 in sequence, thereby movably mounting the base 21 on the bolt 31.

[0045] In other embodiments, the guiding mechanism is a screw, and also includes two nuts 32 that cooperate with the screw. The two nuts 32 are screwed onto the two free ends of the screw and abut against the first outer wall 11 and the second outer wall 12, respectively. The nuts 32 limit the movement of the screw. One end of the screw passes through a through hole 1200 in sequence through the first outer wall 11, the first inner wall 211, the second inner wall 212, and the second outer wall 12, thereby movably mounting the base 21 on the screw. The first outer wall 11 and the second outer wall 12 simultaneously limit the movement of the base 21. In another embodiment, the guiding mechanism is a pin, with a cotter pin at one end. The cotter pin passes through a hole in the pin, thereby limiting the movement of the pin.

[0046] Please refer to Figures 1 to 4As shown, a latch 15 is formed at the top of both the first outer wall 11 and the second outer wall 12, and the latch 15 is used to limit the steel strand 300. Furthermore, the size of the latch 15 is set to be larger than the circumference of the steel strand 300, thus avoiding damage caused by scratching the steel strand 300. In a preferred embodiment, the curved surface of the latch 15 that mates with the steel strand 300 is provided with a wear-resistant material, such as a polymer coating or a metal-ceramic coating.

[0047] Please refer to Figures 1 to 8 As shown, this utility model discloses a flexible photovoltaic support, which includes steel strands 300, columns 400, and a steel strand positioning structure 100 as described in any of the above embodiments. This is one embodiment of the flexible photovoltaic support of this utility model. Secondly, this utility model also discloses a flexible photovoltaic support, which includes steel strands 300, columns 400, a drive mechanism 500, and a steel strand positioning structure 100 as described in any of the above embodiments. This is another embodiment of the flexible photovoltaic support of this utility model. The steel strands 300 extend along a first direction, the inclined beams 200 extend along a second direction, and the columns 400 extend along a third direction. In one embodiment of the flexible photovoltaic bracket of this utility model, the fixing seat 1 of the steel strand positioning structure 100 is set at one end of the column 400. The fixing seat 1 is preferably an inclined beam 200, a structural component fixedly connected to the inclined beam 200, or a mounting seat set at the top of the column 400. The angle of the steel strand 300 cannot be adjusted during operation. In another embodiment of the flexible photovoltaic bracket of this utility model, the fixing seat 1 is preferably an inclined beam 200 of the flexible photovoltaic bracket or a structural component fixedly connected to the inclined beam 200. The inclined beam 200 is set at the top of the column 400. The driving mechanism 500 is connected to the inclined beam 200. The driving mechanism 500 drives the inclined beam 200 to rotate relative to the column 400, thereby driving the steel strand 300 to rotate, and then driving the photovoltaic module set on the steel strand 300 to rotate, so as to obtain the maximum power generation. The drive mechanism 500 is preferably an electric push rod, a worm gear rotary drive, or other existing structural forms such as those described in patent CN218829784U. The drive mechanism 500 and its transmission connection with the inclined beam 200 are prior art and will not be described in detail here. Preferably, in embodiment two, the fixing seat 1 of the steel strand positioning structure 100 is located at the front end and / or rear end of the inclined beam 200 along the second direction, that is, the fixing seat 1 is located at at least one end of the inclined beam 200. With this arrangement, the steel strands 300 at multiple locations on the column 400 and / or the inclined beam 200 can be limited and fixed as needed, and the steel strands 300 at each location will not rub against each other, thus protecting the steel strands 300 to the greatest extent.

[0048] The steel strand 300 has a first end extending outward across the first outer wall 11 and a second end extending outward across the second outer wall 12. The first end and the second end are respectively used to connect with other elements in the flexible photovoltaic bracket of this utility model.

[0049] In summary, because this utility model provides a cable fixing member 2 on the fixing seat 1 of the steel strand positioning structure 100, the displacement of the steel strand 300 caused by construction errors or rotation under the drive of the inclined beam 200 is transferred to the cable fixing member 2. That is, the cable fixing member 2 moves relative to the fixing seat 1. There is no relative displacement between the steel strand 300 and the entire cable fixing member 2, especially between the steel strand 300 and the locking member 22. Therefore, there will be no friction between the steel strand 300 and the locking member 22 without relative displacement, and the wear of the outer protective layer of the steel strand 300 will not cause the steel strand 300 to break. This can both meet the displacement of the steel strand 300 during rotation or due to construction errors and protect the coating of the steel strand 300. Meanwhile, since the steel strand 300 can move relative to the inclined beam 200 in the first direction, the phenomenon of load accumulation between the steel strand 300 and the inclined beam 200 can be avoided, thereby preventing damage to the inclined beam 200 due to excessive force and improving the life of the flexible photovoltaic support. In addition, after adopting this utility model, compared with replacing the steel strand, the replacement of the base 21 and the locking part 22 of this utility model is simpler, which greatly improves the replacement efficiency and saves maintenance costs.

[0050] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model.
