[0002] A flexible photovoltaic bracket is a specially designed bracket for a solar photovoltaic system. The flexible bracket solution changes the purlins in the traditional rigid bracket solution to steel strands, and it is a photovoltaic installation system that can be flexibly adjusted according to various factors such as terrain, lighting conditions, and seasonal changes. It is applicable to large-slope mountain projects and projects that require high clearance and reduced pile foundations; The existing flexible photovoltaic brackets are usually of a fixed-angle structure for photovoltaic panels, and the angles of the photovoltaic panels cannot be adjusted. The power of the photovoltaic panels fluctuates greatly with the sunrise time. Moreover, most of the steel cables on the existing flexible photovoltaic brackets have only one anti-disconnection structure, and the connection of the steel cables cannot be effectively protected after the anti-disconnection structure fails.

[0018] The present invention provides the following embodiments Embodiment 1 The embodiment of the present invention provides a flexible tracking photovoltaic bracket that is convenient for angle adjustment, as Figure 1-9As shown in the figure, it includes: a photovoltaic panel 1. A number of photovoltaic panels 1 are all installed on two parallel receiving steel cables 11 through a connecting component 3. Both ends of the two receiving steel cables 11 are connected to a rotating component 5 through a secondary anti-disconnection structure. The secondary anti-disconnection structure includes a check clip 64 and a wire clamping device 7. The rotating component 5 is installed on a basic support component 2. Below the receiving steel cable 11, there is a wind resistance structure 4. The wind resistance structure 4 includes a central wind resistance cable 43 and two groups of symmetrically arranged side wind resistance cables 42. The two side wind resistance cables 42 are symmetrically arranged obliquely above the central wind resistance cable 43; It also includes an automatic lubrication component 8. The automatic lubrication component 8 is used to automatically add grease to the rotating component 5.

[0019] The working principle and beneficial effects of the above technical solution are as follows: The basic support component 2 holds the rotating component 5 in the air. The rotating component 5 is connected to the receiving steel cable 11. A number of photovoltaic panels 1 are installed on the receiving steel cable 11 through a connecting component 3, realizing the suspension of the photovoltaic panels 1. The rotating component 5 drives the receiving steel cable 11 and the wind resistance structure 4 to rotate, so that the photovoltaic panels 1 on the receiving steel cable 11 can rotate. The wind resistance structure 4 connects the receiving steel cable 11 and the wind resistance structure 4 into several local wholes to enhance the wind resistance of the overall structure. The automatic lubrication component 8 automatically adds grease to the rotating component 5; The present invention uses the basic support component 2 to cooperate with the receiving steel cable 11 to hold the photovoltaic panel 1 in the air. This design can reduce the land occupation of the photovoltaic support, improve the space utilization rate. Compared with the traditional photovoltaic support, it reduces the steel consumption, reduces the cost, and can avoid the terrain factors of mountain undulations. The rotating component 5 realizes the rotation of the photovoltaic panel 1. This design enables the photovoltaic panel 1 to rotate 180° in all angles, and can follow the position of the sun at any time period. The connection between the rotating component 5 and the receiving steel cable 11 uses a secondary anti-disconnection structure in series (that is, the check clip 64 and the wire clamping device 7), which can ensure the stability of the connection between the receiving steel cable 11 and the rotating component 5. The wind resistance structure 4 cooperates with two side wind resistance cables 42 and a central wind resistance cable 43 to increase the stability of the wind resistance frame 41. The aggregation of several individual wind resistance units improves the overall wind resistance ability. This design ensures that when the photovoltaic panel 1 faces the wind in the suspended state, the undulation of the photovoltaic panel 1 can be reduced to the greatest extent. At the same time, the design of the automatic lubrication component 8 ensures that when the rotating component 5 rotates reciprocally, the wear between its structures is reduced to the greatest extent, ensuring the service life of the rotating component 5 and reducing the workload of maintenance personnel.

[0020] Embodiment 2 On the basis of Embodiment 1, the basic support assembly 2 includes two foundation bases 21. Main support columns 22 are connected to the foundation bases 21. A beam 25 is bolted between the main support columns 22. On the beam 25, a first stay cable 23 is symmetrically connected along the direction of the side to receive the steel cable. The other end of the first stay cable 23 is riveted into the ground. Two second stay cables 24 are staggeredly arranged between the two main support columns 22. A rotating assembly 5 is installed on the beam 25.

[0021] The working principle and beneficial effects of the above technical solution are as follows: The foundation base 21 is buried underground for fixation. The main support column 22 on the foundation base 21 bears the beam 25. The rotating assembly 5 installed on the beam 25 overheads and rotates the received steel cable 11. The first stay cable 23 protects the main support column 22 and the beam 25 to be stable in the direction of receiving the steel cable 11 through stay cable. The second stay cable 24 connects the two main support columns 22 to strengthen their stability and strength. The present invention uses the main support column 22 and the beam 25 to realize the overhead of the received steel cable 11 and the photovoltaic panel 1. This design can reduce the land occupation of the photovoltaic support structure, improve the land utilization rate, reduce the consumption of steel, and reduce the cost of the basic support assembly 2.

[0022] Embodiment 3 On the basis of Embodiment 1, the coupling assembly 3 includes a clamp 31. The clamp 31 is bolted below the substrate 32. A received steel cable 11 is provided between the clamp 31 and the substrate 32. A clip 33 is bolted above the substrate 32. A photovoltaic panel 1 is nested between the substrate 32 and the clip 33.

[0023] The beneficial effect of the above technical solution is as follows: The clamp 31 holds the received steel cable 11 tightly below the substrate 32 so that the substrate 32 is stably connected to the received steel cable 11. The clip 33 above the substrate 32 clamps the photovoltaic panels 1 at both ends on the substrate 32, so that the photovoltaic panels 1 are overhead on the received steel cable 11. The present invention uses the clamp 31, the substrate 32 and the clip 33 to ensure the connection between the photovoltaic panel 1 and the received steel cable 11. This design can connect two photovoltaic panels 1 into a whole, and the coupling assembly 3 is an independent assembly. When a photovoltaic panel 1 fails, it can be disassembled separately without affecting other photovoltaic panels 1.

[0024] Embodiment 4 On the basis of Embodiment 1, the wind resistance structure 4 includes a plurality of wind resistance frames 41. The tops of the plurality of wind resistance frames 41 are all sleeved on the received steel cable 11. On the left and right of the middle of the plurality of wind resistance frames 41, side wind resistance cables 42 are sleeved. A central wind resistance cable 43 is sleeved below the plurality of wind resistance frames 41. The middle sections of the two side wind resistance cables 42 and the central wind resistance cable 43 are parallel to each other. Both ends of the two side wind resistance cables 42 and the central wind resistance cable 43 are connected to the rotating assembly 5.

[0025] The beneficial effects of the above technical solution are as follows: The central wind-resistant cable 43 and the two side wind-resistant cables 42 are arranged with staggered ends and parallel in the middle to strengthen the longitudinal tension. The central wind-resistant cable 43 and the two side wind-resistant cables 42 are connected to the wind-resistant frame 41, transferring the longitudinal tension to the wind-resistant frame 41. The wind-resistant frame 41 is connected to the receiving steel cable 11 at the top, forming a triangular stable structure to achieve a local stable wind-resistant structure. Then, the combination of several wind-resistant frames 41 strengthens the overall wind resistance. The present invention uses the design of the central wind-resistant cable 43 and the bilateral wind-resistant cables 42 to achieve wind resistance. This design can strengthen the stability of the wind-resistant frame 41 on the windward side, prevent the wind-resistant frame 41 from swaying left and right and causing overturning, and the two ends of the central wind-resistant cable 43 and the bilateral wind-resistant cables 42 are arranged crosswise, strengthening the tension between the wind-resistant frame 41 and the receiving steel cable 11.

[0026] Embodiment 5 Based on Embodiment 1, the rotating assembly 5 includes a rotating shaft seat 51. The two rotating shaft seats 51 are symmetrically installed on the beam 25. A square-headed round shaft 52 is rotatably connected to both rotating shaft seats 51. A slide rail 53 is provided between the two rotating shaft seats 51. A rack 54 is slidably connected in the slide rail 53. The rack 54 meshes with a gear 55. The gear 55 is installed on the square-headed round shaft 52. Hydraulic expansion rods 56 are connected to both ends of the rack 54. The hydraulic expansion rods 56 are installed on the beam 25. A limit stop bar 57 and a steel cable frame 6 are sequentially installed at one end of the square-headed round shaft 52. An anti-disengagement stop 58 is installed at the other end of the square-headed round shaft 52. A stroke stop nail 59 is installed on the beam 25. The stroke stop nail 59 cooperates with the limit stop bar 57. A housing 510 is installed on the rotating shaft seat 51.

[0027] The steel cable frame 6 includes a double-layer chuck 61. The double-layer chuck 61 is installed on the square-headed round shaft 52. A number of wire passing holes 62 are provided on the double-layer chuck 61. The receiving steel cable 11, the side wind-resistant cable 42, and the central wind-resistant cable 43 are respectively sleeved in the wire passing holes 62. A wire clamping device 7 is provided between the double-layer chucks 61. A number of inner anchor sleeves 63 are threadedly connected to the side of the double-layer chuck 61 close to the beam 25. A check clip 64 is nested in the inner anchor sleeve 63. An outer anchor sleeve 65 is threadedly connected to the inner anchor sleeve 63. The wire clamping device 7 and the inner anchor sleeve 63 are in one-to-one correspondence with the wire passing holes 62.

[0028] The wire clamping device 7 includes a bottom clamping plate 71. The two ends of the bottom clamping plate 71 are fixed in the double-layer chuck 61. An upper clamping plate 72 is provided above the bottom clamping plate 71. The upper clamping plate 72 is slidably connected in a guide bar 73. The guide bar 73 is arranged on the double-layer chuck 61. An outer hoop 74 is provided outside the bottom clamping plate 71 and the upper clamping plate 72. The outer hoop 74 is fixedly connected to the bottom clamping plate 71. Threaded grooves 75 are provided on both the upper clamping plate 72 and the outer hoop 74. A fastening stud 76 is threadedly connected in the threaded groove 75. The fastening stud 76 passes through and is slidably connected to the double-layer chuck 61.

[0029] The beneficial effects of the above technical solution are as follows: When the photovoltaic panel 1 rotates, the hydraulic telescopic rods 56 at both ends extend and contract respectively, pushing the rack 54 to slide along the slide rail 53. The rack 54 meshes with the gear 55, and the gear 55 drives the square-headed round shaft 52 to rotate on the rotating shaft seat 51. When the square-headed round shaft 52 rotates, the cable support frame 6 rotates accordingly. When the cable support frame 6 rotates 90° forward or backward, the limit stop bar 57 will contact the stroke stop nail 59, preventing the square-headed round shaft 52 and the cable support frame 6 from rotating beyond the stroke. The anti-disengagement block 58 ensures that the square-headed round shaft 52 does not disengage from the rotating shaft seat 51 during rotation; The double-layer chuck 61 on the cable support frame 6 connects and holds the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42. The receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 pass through the wire threading hole 62 and are connected to the double-layer chuck 61 through the cable clamp 7 and the check valve clip 64. After the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 pass through the check valve clip 64, the check valve clip 64 is nested inside the inner anchor sleeve 63, so that the check valve clip 64 increases the friction force with the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 under the action of pressure. The outer anchor sleeve 65 is threadedly connected to the inner anchor sleeve 63, and the outer anchor sleeve 65 presses against the check valve clip 64 to prevent the check valve clip 64 from retracting; Before the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 pass through the cable clamp 7, slide the upper clamping plate 72 upward to the topmost position. After the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 pass through the cable clamp 7, lower the upper clamping plate 72 to the lowest position. Then, select a suitable fastening stud 76 and screw it into the space between the upper clamping plate 72 and the outer hoop 74. The fastening stud 76 presses the upper clamping plate 72 and the bottom clamping plate 71, thereby increasing the friction force between the upper clamping plate 72 and the bottom clamping plate 71 and the lock, so that the lock cannot disengage from the upper clamping plate 72 and the bottom clamping plate 71; The present invention realizes the rotation of the photovoltaic panel 1 by the meshing of the rack 54 and the gear 55. This design adopts a horizontal structure, which can greatly reduce the influence of the tension on the receiving cable 11 on the rotating assembly 5, and avoid the connection failure between the basic support assembly 2 and the rotating assembly 5 under the action of wind. And the hydraulic telescopic rod 56 is used as the power source to drive the rack 54 and the gear 55. This design can reduce the influence on the driving structure in harsh environments and ensure the stable operation of the driving structure in harsh environments; The cable support frame 6 of the present invention is connected to the receiving cable 11, the central wind-resistant cable 43, and the side wind-resistant cable 42 by the cable clamp 7 and the check valve clip 64. This design ensures the connection stability through a double cable locking structure and prevents the collapse of the entire structure caused by the failure of a single-layer connection; The upper clamping plate 72 of the present invention can slide flexibly within the guide bar 73. This design enables the upper clamping plate 72 and the bottom clamping plate 71 to adapt to riggings of any size. Meanwhile, the self-locking property of the fastening stud 76 and the upper clamping plate 72 ensures that the lock cannot be disengaged from the clamping of the upper clamping plate 72 and the bottom clamping plate 71.

[0030] Embodiment 6 Based on Embodiment 1, the automatic lubrication assembly 8 includes a grease storage rack 81. The two grease storage racks 81 are symmetrically installed on the left and right of the outer shell 510. Slide rods 82 are slidably connected to the left and right of the grease storage racks 81. Arc-shaped clamping plates 83 are fixed on the slide rods 82. A first elastic compression member 84 is sleeved on the slide rods 82 between the arc-shaped clamping plates 83 and the grease storage racks 81. A grease storage tank 85 is provided between the arc-shaped clamping plates 83. A pressing cover 86 is slidably connected within the grease storage tank 85. An oil outlet 87 is provided on the grease storage tank 85. The oil outlet 87 is slidably connected within an oil outlet flat port 88. The oil outlet flat port 88 is arranged above the rack 54 and penetrates and is fixed on the outer shell 510. A lubrication structure 9 is provided at the top of the grease storage rack 81.

[0031] The lubrication structure 9 includes a top plate 91. The top plate 91 is arranged at the top of the grease storage tank 85 and is threadedly connected to a push rod 92. The push rod 92 is slidably connected to a pressing frame 93. The middle of the pressing frame 93 is hingedly connected to a pressing handle 94. A forward card 95 is sleeved on the push rod 92. The forward card 95 cooperates with the pressing handle 94. A second elastic compression member 96 is sleeved on the push rod 92 between the forward card 95 and the pressing frame 93. A return card 97 is hingedly connected to the top of the pressing frame 93. The return card 97 is slidably connected to the push rod 92. A third compression elastic member 98 is provided on the push rod 92 between the return card 97 and the pressing frame 93. The other end of the pressing handle 94 is hingedly connected to a connecting rod 99. The other end of the connecting rod 99 is hingedly connected to the working end of the hydraulic telescopic rod 56.

[0032] The beneficial effects of the above technical solution are as follows: When adding grease between the gear 55 and the rack 54, the grease storage tank 85 is pushed into the arc-shaped clamping plates 83 of the tank rack 81. Under the action of the first elastic compression member 84, the sliding rod 82 pushes the arc-shaped clamping plates 83 to squeeze the grease storage tank 85 to ensure the fixation of the grease storage tank 85. The grease outlet 87 on the grease storage tank 85 is inserted into the flat grease outlet 88. When the hydraulic telescopic rod 56 extends, it drives the connecting rod 99 to press the pressure handle 94. The pressure handle 94 rotates around the extrusion frame 93 to squeeze the forward card 95 downward. Under the action of the second elastic compression member 96, the forward card 95 and the push rod 92 are locked to drive the push rod 92 downward. At the same time, the return card 97 locks the push rod 92 under the action of the third compression elastic member 98 to prevent the push rod 92 from retracting. When the push rod 92 advances, the return card 97 advances with the push rod 92 until they are perpendicular to each other to release the lock. The return card 97 slides and resets along the push rod 92 under the action of the third compression elastic member 98. The push rod 92 then pushes the top plate 91, causing the top plate 91 to push the extrusion cover 86 to slide in the grease storage tank 85, squeezing the grease in the grease storage tank 85 from the grease outlet 87 into the flat grease outlet 88. The flat grease outlet 88 applies the grease to the rack 54. When the hydraulic telescopic rod 56 contracts, the connecting rod 99 retracts and no longer applies pressure to the pressure handle 94. Under the action of the second elastic compression member 96, the extrusion forward card 95 slides upward along the push rod 92. The forward card 95 pushes the pressure handle 94 to rotate and reset, waiting for the next extension of the hydraulic telescopic rod 56. When the grease in the grease storage tank 85 is consumed, the return card 97 is pressed downward to pull the push rod 92 upward to reset it, and a new grease storage tank 85 is replaced; The present invention utilizes the grease storage tank 85 and the flat grease outlet 88 to output grease. This design facilitates the storage and addition of grease. In combination with the design of the sliding rod 82 and the arc-shaped clamping plates 83, it not only ensures that a new grease storage tank 85 can be quickly replaced when the grease in the grease storage tank 85 is consumed, but also ensures the stability of the grease storage tank 85 in the tank rack 81, preventing the grease storage tank 85 from falling off due to vibration. Moreover, this design makes the grease storage environment better, and the flat grease outlet 88 and the grease outlet 87 can be quickly connected. At the same time, the design of the forward card 95 and the return card 97 can ensure the one-way advancement of the push rod 92, ensuring that there is no empty stroke between the top plate 91 and the extrusion cover 86 (i.e., there is a gap between the top plate 91 and the extrusion cover 86), and grease cannot be extruded. At the same time, the design of the connecting rod 99 and the pressure handle 94 ensures that grease is only extruded to the meshing part of the rack 54 when the hydraulic telescopic rod 56 extends to push the rack 54 and the gear 55 to mesh. This design can maximize the utilization rate of grease and reduce the waste of grease.
