Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a connecting bridge structure and a linked tracking photovoltaic system. Background Technology

[0002] In existing connection bridge structures for linked tracking photovoltaic systems, interference is prone to occur between the connection bridge structure and the linkage synchronous shaft. To solve the problem of interference between the linkage synchronous shaft and the connection bridge, patent CN219458984U discloses a connection bridge that can be pushed away from the photovoltaic module by the linkage synchronous shaft, thereby avoiding interference with the linkage synchronous shaft. However, during the process of being pushed by the linkage synchronous shaft, friction will occur between the connection bridge structure and the linkage synchronous shaft, causing wear on the synchronous shaft and the connection bridge structure, affecting the service life. At the same time, it will also affect the smoothness of the synchronous shaft rotation, thus affecting the normal operation of the photovoltaic tracking bracket. Utility Model Content

[0003] The purpose of this invention is to provide a connecting bridge structure and a linked tracking photovoltaic system that can avoid interference with the linkage synchronous shaft and ensure the smooth rotation of the synchronous shaft.

[0004] To achieve the above objectives, this utility model adopts the following technical solution one:

[0005] A connecting cable tray structure includes a first crossbar, a second crossbar, a connecting longitudinal bar, a first rod, and a second rod. The first crossbar and the second crossbar are arranged in parallel. The two ends of the connecting longitudinal bar are respectively connected to one end of the first crossbar and the corresponding end of the second crossbar. The first rod is connected to the other end of the first crossbar and has a first free end pointing to the second rod. The second rod is connected to the other end of the second crossbar and has a second free end pointing to the first rod. The first free end and the second free end are separated by an open interval.

[0006] As a further improvement of the present invention, the first rod and the second rod each include a first tube and a second tube. The second tube is respectively inserted into or sleeved on the first tube. The first tube and the corresponding second tube can extend and retract relative to each other. When the first tube and the corresponding second tube extend relative to each other, the first free end and the second free end are close to each other. When the first tube and the corresponding second tube retract relative to each other, the first free end and the second free end are far apart from each other.

[0007] As a further improvement of the present invention, the first rod and the second rod each include a first tube and a second tube. The second tube is respectively inserted into or sleeved on the first tube. The first tube and the corresponding second tube can extend and retract relative to each other. When the first tube and the corresponding second tube extend relative to each other, the first free end and the second free end are close to each other. When the first tube and the corresponding second tube retract relative to each other, the first free end and the second free end are far apart from each other.

[0008] As a further improvement of the present invention, the limiting connector is a limiting pin, the adjustable hole is a bolt hole with multiple toothed portions, the toothed portions are in two rows, the upper row of toothed portions and the lower row of toothed portions are in a one-to-one correspondence; the toothed portions include at least a first pair of toothed portions and a second pair of toothed portions, and the limiting pin can pass through the circular hole and interchange between the first pair of toothed portions and the second pair of toothed portions.

[0009] As a further improvement of the present invention, the connecting rod includes a third rod, a fourth rod, and a cover plate. The third rod is fixed to the first crossbar, the fourth rod is fixed to the second crossbar, one end of the cover plate is connected to the third rod, and the other end is connected to the fourth rod, so that one end of the connecting rod is connected to the first crossbar and the other end of the connecting rod is connected to the second crossbar.

[0010] As a further improvement of the present invention, at least one reinforcing plate is provided between the first crossbar and the second crossbar. The reinforcing plate includes a first plate and a second plate, and the first plate and the second plate are fixedly and adjustablely connected.

[0011] As a further improvement of the present invention, the two opposite walls of the third rod and the two opposite walls of the fourth rod are respectively provided with a first narrow groove, and the cover plate is provided with a first through hole corresponding to the first narrow groove.

[0012] The first plate and the second plate are provided with a second narrow groove. The first plate and the second plate each include a main body and a tongue plate. The second narrow groove extends from the main body to the tongue plate. The tongue plate is also provided with a second through hole. The second through hole on the first plate corresponds to the second narrow groove on the second plate. The second through hole on the second plate corresponds to the second narrow groove on the first plate.

[0013] As a further improvement of the present invention, the technical solution also includes a plurality of supporting ear plates, which are respectively disposed at opposite ends of the first crossbar and opposite ends of the second crossbar. The supporting ear plates are distributed on the two outer sides of the first crossbar and the second crossbar, and the two outer sides include a first outer side of the first crossbar away from the second crossbar and a second outer side of the second crossbar away from the first crossbar.

[0014] To achieve the above objectives, this utility model adopts the following technical solution two:

[0015] A linkage tracking photovoltaic system includes a first tracking photovoltaic system, a second tracking photovoltaic system, and a linkage synchronous shaft. The first tracking photovoltaic system includes a first main shaft and a first drive device, which are drively connected to the first main shaft. The second tracking photovoltaic system includes a second main shaft and a second drive device, which are drively connected to the second main shaft. The two ends of the linkage synchronous shaft are drively connected to the first drive device and the second drive device, respectively. The first tracking photovoltaic system and the second tracking photovoltaic system each include a connecting bridge structure as described above. The connecting bridge structure is respectively disposed on the first main shaft and the second main shaft. The linkage synchronous shaft can pass between the first free end and the second free end of the connecting bridge structure.

[0016] As a further improvement of this utility model, the second technical solution is that the disconnection distance between the first free end and the second free end of the connecting bridge structure is greater than the maximum width of the linkage synchronous shaft and less than the diameter of the walking wheel of the cleaning robot.

[0017] Compared to existing technologies, this utility model, by setting a connecting bridge structure on the linkage tracking photovoltaic system, includes a first rod and a second rod extending in the longitudinal direction. The first free end of the first rod and the second free end of the second rod are separated by a disconnection, thereby avoiding interference between the connecting bridge structure and the linkage synchronization shaft when the linkage tracking photovoltaic system is applied, and ensuring the smooth rotation of the linkage synchronization shaft.

[0041] Please refer to Figures 1 to 18As shown, this utility model discloses a connecting bridge structure 100, applied to each of the two tracking photovoltaic systems 200 in a linked tracking photovoltaic system 300. Each of the tracking photovoltaic systems 200 has a main shaft 400 extending in a front-rear direction and a plurality of photovoltaic modules 500 arranged in a row along the front-rear direction. The photovoltaic modules 500 include at least a first photovoltaic module 501 and a second photovoltaic module 502 arranged at intervals. The connecting bridge structure 100 is located between the first photovoltaic module 501 and the second photovoltaic module 502. Therefore, the connecting bridge structure 100 of this utility model is an intermediate bridge pipe applied to each tracking photovoltaic system 200. The connecting bridge structure 100 of this utility model includes a first crossbar 1, a second crossbar 2, a connecting longitudinal bar 4, a first rod 31, and a second rod 32. The first crossbar 1 and the second crossbar 2 are arranged in parallel. The two ends of the connecting rod 4 are respectively connected to one end of the first crossbar 1 and the second crossbar 2. The first rod 31 is connected to the other end of the first crossbar 1 and has a first free end 310 pointing to the second rod 32. The second rod 32 is connected to the other end of the second crossbar 2 and has a second free end 320 pointing to the first rod 31. The first free end 310 and the second free end 320 are separated by a gap. As is known to those skilled in the art, the first tracking photovoltaic system 201 in the linkage tracking photovoltaic system 300 has a first main shaft 401 and the second tracking photovoltaic system 202 has a second main shaft 402. The first main shaft 401 and the second main shaft 402 are connected by the linkage synchronous shaft 203. Therefore, when the first free end 310 and the second free end 320 are set with a disconnected interval and the connection bridge structure 100 of this utility model is applied to the linkage tracking photovoltaic system 300, interference between the intermediate bridge pipe and the linkage synchronous shaft 203 is avoided, ensuring the smooth rotation of the linkage synchronous shaft 203.

[0042] Please refer to Figures 1 to 18As shown, the connecting cable tray structure 100 defines mutually perpendicular horizontal and vertical directions. The horizontal direction is perpendicular to the front-back direction, and the vertical direction is parallel to the front-back direction. The connecting cable tray structure 100 includes a first crossbar 1 and a second crossbar 2, which extend parallel to each other in the horizontal direction and are arranged opposite each other in the vertical direction. The first crossbar 1 is used to abut against the frame of the first photovoltaic module 501, and the second crossbar 2 is used to abut against the frame of the second photovoltaic module 502. The connecting cable tray structure 100 includes a first rod 31 and a second rod 32 extending in the vertical direction. The first rod 31 is connected to the first crossbar 1 and has a first free end 310 pointing towards the second rod 32. The second rod 32 is connected to the second crossbar 2 and has a second free end 320 pointing towards the first rod 31. The first free end 310 and the second free end 320 are separated by a gap. By configuring the intermediate bridge frame tube, which is prone to interference with the linkage synchronous shaft 203, into two disconnected rods, namely the first rod 31 and the second rod 32, when the connecting bridge structure 100 is applied to each of the two tracking photovoltaic systems 200 of the linkage tracking photovoltaic system 300, the linkage synchronous shaft 203 passes through the disconnection of the intermediate bridge frame tube, avoiding interference between the intermediate bridge frame tube and the linkage synchronous shaft 203 during rotation; at the same time, the intermediate bridge frame tube rotates synchronously with the photovoltaic module 500, avoiding shading of the photovoltaic module 500 by the intermediate bridge frame tube. In other embodiments not shown, the first crossbar 1 and the second crossbar 2 can also be two side frames of the first photovoltaic module 501 and the second photovoltaic module 502 close to each other, which, while supporting the photovoltaic panel, also allow the cleaning robot to pass through, thus achieving the purpose of saving installation costs.

[0043] Please refer to Figures 3 to 9 , Figure 13 and Figure 18As shown, both the first rod 31 and the second rod 32 include a first tube 301 and a second tube 302. The second tube 302 is respectively inserted into or sleeved on the first tube 301, and the first tube 301 and the corresponding second tube 302 can extend and retract relative to each other. When the first tube 301 and the corresponding second tube 302 extend relative to each other, the first free end 310 and the second free end 320 are close to each other. When the first tube 301 and the corresponding second tube 302 retract relative to each other, the first free end 310 and the second free end 320 are far apart from each other. With this configuration, the first rod 31 and the second rod 32, which are disconnected on both sides, are preferably set as telescopic tubes, which can better adapt to the misalignment of the linkage synchronous shaft 203 caused by terrain or assembly errors. By adjusting the size of the telescopic tube, sufficient movement space is provided for the linkage synchronous shaft 203, avoiding interference between the first rod 31 and the second rod 32 and the linkage synchronous shaft 203, and preventing the linkage synchronous shaft 203 from being unable to provide orientation. The cross-sections of the first tube 301 and the second tube 302 can be closed or open. In addition to square closed cross-sections, they can also be C-shaped or U-shaped open cross-sections, as long as they can realize the telescopic structure of the first rod 31 or the second rod 32.

[0044] Please refer to Figure 3 , Figure 4 , Figure 9 , Figure 13 and Figure 18 As shown, the connecting cable tray structure 100 of this utility model also includes a limiting connector (e.g., a limiting pin 5). One of the first tube 301 and the second tube 302 is provided with an adjustable hole 3001, and the other is provided with a round hole 3002. The limiting connector passes through the round hole 3002 and the adjustable hole 3001 to telescopically connect the first tube 301 and the second tube 302 corresponding to the first tube 301. With this configuration, the two parts of each telescopic tube (first rod 31 / second rod 32), namely the first tube 301 and the corresponding second tube 302, can be connected as a whole, and the adjustable hole 3001 ensures the possibility of telescopic movement.

[0045] Please refer to Figure 3 , Figure 9 , Figure 13 and Figure 18 As shown in the specific embodiment, the limiting connector is a limiting pin 5. (See also...) Figure 18As shown, the adjustable hole 3001 is a bolt hole with multiple toothed portions 3000. The toothed portions 3000 are arranged in two rows, with the upper row of toothed portions 3000 corresponding one-to-one with the lower row. Each toothed portion 3000 includes at least a first pair of toothed portions 30001 and a second pair of toothed portions 30002 arranged in the front-rear direction. The limiting pin 5 can pass through the circular hole 3002 and interchange between the first pair of toothed portions 30001 and the second pair of toothed portions 30002. The telescopic tube described above uses multiple bolt holes to restrict the displacement of the limiting pin 5. Compared to a long, narrow hole, this avoids the possibility of the limiting pin 5 failing, ensuring the stability of the limiting connection.

[0046] Please refer to Figure 9 and Figure 13 As shown, both the first tube 301 and the second tube 302 are hollow square tubes. The first tube 301 has bolt holes (i.e., adjustable holes 3001) on both opposite walls, and the second tube 302 has round holes 3002 on both opposite walls. This arrangement of hollow square tubes for both tubes facilitates the forming of the adjustable holes 3001 and round holes 3002 on the first tube 301 and the second tube 302, respectively. Furthermore, it facilitates the connection of the limiting connector (e.g., limiting pin 5) to the first tube 301 and the corresponding second tube 302 as a single unit, and allows for the movement of the limiting pin 5 to adjust the distance between the first free end 310 and the second free end 320.

[0047] Please refer to Figure 7 , Figure 8 , Figure 10 , Figure 12 , Figure 14 and Figure 15As shown, the connecting cable tray structure 100 also includes connecting longitudinal rods 4. The connecting longitudinal rods 4 include a third rod 41, a fourth rod 42, and a cover plate 43. The third rod 41 and the fourth rod 42 are both hollow square tubes. Besides square tubes, the third rod 41 and the fourth rod 42 can also have other cross-sectional shapes, such as U-shaped or C-shaped. The third rod 41 is fixed to the first crossbar 1, and the fourth rod 42 is fixed to the second crossbar 2. The cover plate 43 includes a base 430 and two side portions 431 extending downward from the base 430; that is, in this specific embodiment, the cover plate 43 is U-shaped; besides U-shaped, the cover plate 43 can also be C-shaped or square. The base 430 and the two side portions 431 partially surround and cover the third rod 41 and the fourth rod 42. One end of the cover plate 43 is connected to the third rod 41 and the other end is connected to the fourth rod 42, thereby connecting one end of the connecting longitudinal rod 4 to the first crossbar 1 and the other end of the connecting longitudinal rod 4 to the second crossbar 2. Therefore, the function of the connecting longitudinal rod 4 is to connect the first crossbar 1 and the second crossbar 2 together on opposite sides of the disconnected first rod 31 and second rod 32, making the connecting bridge structure 100 a frame structure, serving as a bridge between the first photovoltaic module 501 and the second photovoltaic module 502. The first rod 31 and the second rod 32 form the rod assembly 3 (although disconnected). Furthermore, the three parts of the connecting longitudinal rod 4—the third rod 41, the fourth rod 42, and the cover plate 43—facilitate molding and assembly.

[0048] Please refer to Figure 8 , Figure 11 , Figure 16 and Figure 17As shown, at least one reinforcing plate 6 is provided between the first crossbar 1 and the second crossbar 2. The reinforcing plate 6 includes a first plate 61 and a second plate 62, which are adjustablely and fixedly connected. Each of the first plate 61 and the second plate 62 includes a main body 60 and a tongue plate 604. The main body 60 includes a main plate 601, a top plate 602 bent above the main plate 601, and a bottom plate 603 bent below the main plate 601. The main body 60 of the first plate 61 and the main body 60 of the second plate 62 each form a "[" shaped space. The tongue plate 604 protrudes forward from the main plate 601 from the top plate 602 and the bottom plate 603. The tongue plate 604 of the first plate 61 is inserted into the "[" shaped space of the second plate 62, and the tongue plate 604 of the second plate 62 is inserted into the "[" shaped space of the first plate 61. First, the reinforcing plate 6 enhances the strength of the frame structure of the connecting cable tray structure 100, providing further support and preventing warping due to prolonged suspension at the disconnected position. The reinforcing plate 6 is configured with two parts: a first plate 61 and a second plate 62. By using interlocking first and second plates 61 and 62, the overall length of the reinforcing plate 6 can be adjusted, and it can also match the three parts of the connecting longitudinal rod 4, better adapting to terrain and installation errors. It should also be noted that, in addition to the structure in this embodiment, the first plate 61 and the second plate 62 can also be integrally formed; or the structural form of the first plate 61 and the second plate 62 is not limited, as long as one of the first plate 61 and the second plate 62 has a cavity that allows the other of the first plate 61 and the second plate 62 to be inserted, thereby achieving a telescopic connection.

[0049] Please refer to Figures 8 to 17As shown, the two opposite walls of the third rod 41 and the two opposite walls of the fourth rod 42 are respectively provided with a first elongated groove 4001, and the two side portions 431 are respectively provided with a first through hole 4002 corresponding to the first elongated groove 4001; the first plate 61 and the second plate 62 are provided with a second elongated groove 6001. Since the first plate 61 and the second plate 62 each include a main body portion 60 and a tongue plate 604, the second elongated groove 6001 extends from the main body portion 60 to the tongue plate 604. The tongue plate 604 is also provided with a second through hole 6002. The second through hole 6002 on the first plate 61 corresponds to the second elongated groove 6001 on the second plate 62, and the second through hole 6002 on the second plate 62 corresponds to the second elongated groove 6001 on the first plate 61. The arrangement of the first narrow groove 4001 and its corresponding first through hole 4002, and the second narrow groove 6001 and its corresponding second through hole 6002, serves two purposes: firstly, it facilitates the connection and positioning of the connecting rod 4 and the reinforcing plate 6 as a single unit; secondly, and more importantly, it allows for the adjustment of the length dimensions of the connecting rod 4 and the reinforcing plate 6, thereby adapting to terrain and installation errors.

[0050] It should be noted that the connecting longitudinal rod 4 at the end is the basic connecting component, while the reinforcing plate 6 in the middle serves to further enhance the strength of the frame. However, once both the connecting longitudinal rod 4 and the reinforcing plate 6 are installed, it is necessary to ensure that both the connecting longitudinal rod 4 and the reinforcing plate 6 can be adjusted in length to prevent deformation of the frame shape of the connecting bridge structure 100.

[0051] Please refer to Figure 7 and Figure 9 As shown, the connecting bridge structure 100 also includes a plurality of support lugs 7. The plurality of support lugs 7 are respectively disposed at opposite ends of the first crossbar 1 and opposite ends of the second crossbar 2. The support lugs 7 are distributed on both outer sides of the first crossbar 1 and the second crossbar 2, including a first outer side of the first crossbar 1 facing away from the second crossbar 2 and a second outer side of the second crossbar 2 facing away from the first crossbar 1. The support lugs 7 are used to support adjacent photovoltaic modules 500, avoiding situations where the photovoltaic modules 500 cannot be fixed using conventional clamping blocks or other existing structures.

[0052] Please refer to Figures 1 to 20As shown, this utility model also relates to a linkage tracking photovoltaic system 300, including a first tracking photovoltaic system 201, a second tracking photovoltaic system 202, and a linkage synchronous shaft 203. The first tracking photovoltaic system 201 includes a first main shaft 401 and a first drive device (unlabeled), which are driveably connected to the first main shaft 401. The second tracking photovoltaic system 202 includes a second main shaft 402 and a second drive device (unlabeled), which are driveably connected to the second main shaft. The two ends of the linkage synchronous shaft are driveably connected to the first drive device and the second drive device, respectively. Both the first tracking photovoltaic system 201 and the second tracking photovoltaic system 202 are provided with a connecting bridge structure 100 as described above. The connecting bridge structure 100 is respectively located on the first main shaft 401 and the second main shaft 402, and the linkage synchronous shaft 203 can pass between the first free end 310 and the second free end 320 of the connecting bridge structure 100. This configuration of the linked tracking photovoltaic system 300, including the connecting bridge structure 100, ensures that during the linked tracking of sunlight by the first tracking photovoltaic system 201 and the second tracking photovoltaic system 202, interference between the intermediate bridge pipe, i.e., the connecting bridge structure 100, and the linkage synchronous shaft 203 during rotation is avoided; at the same time, the intermediate bridge pipe, i.e., the connecting bridge structure 100, rotates synchronously with the photovoltaic module 500, avoiding shading of the photovoltaic module 500.

[0053] The disconnection distance between the first free end 310 and the second free end 320 is greater than the maximum width of the linkage synchronous shaft 203, so that the linkage synchronous shaft 203 can pass between the first free end 310 and the second free end 320. The maximum width mentioned here refers to the horizontal distance between the two closest points on the horizontal plane of the two bridge supports on the maximum projection edge of the linkage synchronous shaft 203 on the horizontal plane (taking the linkage synchronous shaft 203 as a square axis as an example, the maximum projection is the projection formed by the two opposite vertices of the linkage synchronous shaft 203 on the horizontal plane). Please refer to... Figure 19 As shown, taking the linkage synchronous shaft 203 as a square axis as an example, when the linkage synchronous shaft 203 is tilted relative to the first tracking photovoltaic system 201 and the second tracking photovoltaic system 202 due to installation environment limitations, the maximum projection of the linkage synchronous shaft 203 on the horizontal plane is the projection formed by the two diagonal sides on the horizontal plane. A1 is the point closest to the first free end 310 on the edge of the linkage synchronous shaft 203 near the first free end 310, and A2 is the point closest to the second free end 320 on the edge of the linkage synchronous shaft 203 near the second free end 320. The maximum width is the horizontal distance L1 between A1 and A2. Please refer to... Figure 20As shown, when the linkage synchronous shaft 203 is vertically positioned relative to the first tracking photovoltaic system 201 and the second tracking photovoltaic system 202, A3 is the point closest to the first free end 310 on the edge of the linkage synchronous shaft 203 near the first free end 310, and A4 is the point closest to the second free end 320 on the edge of the linkage synchronous shaft 203 near the second free end 320. The maximum width between A3 and A4 is the horizontal distance L2 between A1 and A2. Referring to the attached figures, it can be seen that L1 is greater than L2, meaning that the maximum width is affected by the cross-sectional shape and placement angle of the linkage synchronous shaft 203. When the cross-sectional shape and placement angle are different, the corresponding maximum width is also different. Simultaneously, the disconnection distance between the first free end 310 and the second free end 320 is less than the diameter of the cleaning robot's wheels, allowing the cleaning robot to smoothly pass through the gap between the first free end 310 and the second free end 320 of the connecting bridge structure 100.

[0054] Please refer to Figures 5 to 7 This utility model further includes a clamp 8 and a purlin 9 in each tracking photovoltaic system 200 of the linkage tracking photovoltaic system 300. The purlin 9 is fixedly connected to the first crossbar 1 and the second crossbar 2 in the connecting bridge structure 100, and is also fixedly connected to the clamp 8. When the clamp 8 is sleeved and fixed on the main shaft 400 of each tracking photovoltaic system 200, the connecting bridge structure 100 is fixedly connected to the corresponding main shaft 400, and the connecting bridge structure 100 can rotate together with the photovoltaic module 500 on the corresponding main shaft 400.

[0055] In summary, this invention sets the connecting bridge structure 100 in the linkage tracking photovoltaic system 300 as an intermediate bridge tube with a disconnected interval between the first free end 310 and the second free end 320, thus avoiding interference between the intermediate bridge tube and the linkage synchronous shaft 203 during rotation. The intermediate bridge tube rotates synchronously with the photovoltaic module 500, avoiding shading of the photovoltaic module 500 and improving power generation efficiency.
