Description

Technical Field

[0001] The present invention relates to the technical field of flexible tracking photovoltaic brackets, and in particular to a shock-absorbing flexible tracking photovoltaic bracket. Background Art

[0002] Flexible tracking photovoltaic bracket is a support structure made of prestressed flexible cables or other flexible materials. It can automatically track the movement of the sun so that the photovoltaic panels are always facing the optimal light direction. It monitors the position of the sun in real time through sensors and control systems, and automatically adjusts the direction of the photovoltaic panels to improve power generation efficiency.

[0003] After searching, the Chinese patent with announcement number CN215498806U discloses a flexible photovoltaic support, including a plurality of cable assemblies arranged in sequence on each first support assembly, and a plurality of photovoltaic assemblies are arranged on the cable assembly, so that the photovoltaic assemblies can be tilted to face the sun. Furthermore, the flexible photovoltaic support also includes a connecting cable, which is located between adjacent first support assemblies and can connect the cable assemblies as a whole, and the end of the connecting cable is connected to the second support assembly through an elastic mechanism. The above scheme can effectively reduce the loss of prestress of the connecting cable and avoid its relaxation, especially when the elastic mechanism includes a pulley assembly, a counterweight assembly and an elastic member, when the axial force is not reduced, the maximum stroke of the counterweight assembly and the force of the end elastic member can ensure the strength of the cable assembly to bear the load, thereby improving the stability of the flexible photovoltaic support. However, the above scheme still has the following shortcomings when it is actually used:

[0004] Flexible photovoltaic brackets provide support for photovoltaic panels through steel cables. In actual use, photovoltaic panels are prone to shaking under the action of wind. This will reduce the structural strength of the steel cables in the long run and cause the photovoltaic panels to sink. Improper posture of the photovoltaic panels may result in the photovoltaic panels being unable to fully receive sunlight, thereby affecting the power generation efficiency. Especially in areas with strong winds, frequent shaking and sinking of photovoltaic panels will seriously affect their stability and power generation performance. The flexible photovoltaic bracket proposed in the above scheme cannot make adaptive adjustments to the sinking photovoltaic panels, and the posture of the photovoltaic panels needs to be adjusted manually by tightening the steel cables. Manual adjustment of the posture of the photovoltaic panels requires a lot of time and manpower, especially in large-scale photovoltaic power stations. This adjustment method will become particularly cumbersome and inefficient.

[0005] Therefore, it is necessary to design a shock-absorbing flexible tracking photovoltaic bracket to solve the above problems. Summary of the invention

This process does not require manual intervention, which improves the automation level of the system.

[0056] 2. The traction structure not only has the function of automatically adjusting the posture of the photovoltaic panel when the middle part settles, but also has a wind-resistant effect, ensuring that the photovoltaic panel can always be in the best light-receiving state, thereby improving the power generation efficiency. By combining the wind-resistant cable and the traction structure (including the main traction cable, the auxiliary traction cable and the branch traction cable), the bracket can more effectively resist the upward wind force acting on the photovoltaic panel. This dual design not only enhances the wind resistance of the photovoltaic panel, but also improves its earthquake resistance, providing a more reliable guarantee for the safety and stability of the photovoltaic panel;

[0057] 3. The setting of the pulley structure further optimizes the efficiency and stability of the traction system. When the hood moves downward, the branch traction cable is guided by the two pulleys of the pulley structure, which not only ensures that the branch traction cable can apply tension to the two mounting plates smoothly and unimpeded, but also significantly reduces the direct friction with the hood. This design effectively avoids the wear of the branch traction cable and extends its service life, while ensuring the continuity and stability of the traction force.

[0072] Reference Figure 1-12A shock-absorbing flexible tracking photovoltaic bracket includes a flexible support structure, which is composed of four columns 11 and two steel cables 12.

The two mounting plates 21 are respectively fixed on the two steel cables 12, and the two mounting plates 21 are arranged opposite to each other. The tracking mounting bracket 22 is fixed on the top surface of the two mounting plates 21, and the mounting frame 23 is fixed on the tracking mounting bracket 22, which is used to provide a mounting platform for the photovoltaic panel. Under normal circumstances, the two steel cables 12 are in a taut state, and the hood 63 Located above the two mounting plates 21, a tracking mounting bracket 22 is fixed on the two mounting plates 21, a mounting frame 23 is provided on the tracking mounting bracket 22, and the photovoltaic panel is installed on the mounting frame 23. The tracking mounting bracket 22 has the function of automatically tracking light, so that the photovoltaic panel can rotate with the angle of sunlight, so as to improve the power generation efficiency of the photovoltaic panel. The specific structure and working principle of the tracking mounting bracket 22 are not the innovative part of the present technical solution, and are not shown in the figure, and will not be described in detail here; the four columns 11 are fixed with slide rails 3, and the four slide rails 3 are installed with slide seats 4, and one of the columns 11 is installed with a first hydraulic cylinder 5, and the telescopic end of the first hydraulic cylinder 5 is fixedly connected to the slide seat 4 facing it;

[0073] The four columns 11 are commonly provided with a lifting structure, which includes a hood 63, which is liftably arranged between the two mounting plates 21, and further includes: two lifting plates 61, the two ends of which are respectively fixedly connected to the two adjacent slide seats 4, and the two lifting plates 61 are arranged opposite to each other; two vertical plates 62, one end of the two vertical plates 62 is respectively fixedly connected to the two lifting plates 61, and the other end is respectively fixedly connected to the two ends of the hood 63, and the two vertical plates 62 and the hood 63 together form a U-shaped structure;

[0074] The hood 63 is provided with a traction structure and a sliding structure, the traction structure comprising: a second hydraulic cylinder 71, mounted at one end of the hood 63; a main traction rope 72, one end of which is fixedly connected to the telescopic end of the second hydraulic cylinder 71; a plurality of fixing clips 73, all fixedly sleeved on the main traction rope 72, the plurality of fixing clips 73 are distributed in a linear array along the length direction of the main traction rope 72, and a plurality of traction members are all provided on the hood 63, the traction members comprising: an auxiliary traction rope 741, one end of which is fixedly connected to the fixing clip 73, and the other end Passing through the bottom surface of the hood 63; two branch traction ropes 742, one end of each of the two branch traction ropes 742 is fixedly connected to one end of the auxiliary traction rope 741 located outside the hood 63; two fixing rings 743, respectively fixed on two mounting plates 21, the two fixing rings 743 are respectively fixedly connected to one end of the two branch traction ropes 742 away from the auxiliary traction rope 741; a pulley structure 744, arranged on the bottom surface of the hood 63, the two branch traction ropes 742 are both passed around the pulley structure 744, the pulley structure 744 44 includes: a wheel frame, fixed on the bottom surface of the hood 63; two pulleys, both rotatably mounted on the wheel frame, and the two pulleys are respectively arranged opposite to the two branch traction ropes 742. Under the action of the pulley structure 744, the two branch traction ropes 742 can apply tension to the two mounting plates 21 more stably to avoid wear between the branch traction ropes 742 and the hood 63. When the second hydraulic cylinder 71 is running, its telescopic end can retract and pull the main traction rope 72. When the main traction rope 72 moves, it can pull a number of auxiliary traction ropes 741 through a number of fixing cards 73. Two branch traction ropes 742 are arranged at one end of the auxiliary traction rope 741 away from the main traction rope 72, and the two branch traction ropes 742 are respectively connected to the two mounting plates 21. Therefore, when the main traction rope 72 moves, the several branch traction ropes 742 can synchronously apply upward pulling force to the two mounting plates 21, thereby pulling the settled photovoltaic panel upward, realizing automatic adjustment of the photovoltaic panel posture, and ensuring that the photovoltaic panel can always be in the best light receiving state;

[0075] The sliding structure includes: a slider 81, which is slidably arranged at one end of the hood 63 away from the second hydraulic cylinder 71, and the side of the slider 81 is in contact with the inner surface of the hood 63; a tension spring 82, one end of which is connected to the inner surface of the hood 63, and the other end is connected to the slider 81, and the main traction rope 72 can pull the slider 81 to move when it moves, and the tension spring 82 is used for automatic reset of the slider 81 and the main traction rope 72;

[0076] The two columns 11 are provided with trigger structures, each of which includes a trigger member and an actuator. The trigger member includes: a connecting plate 91 fixed on the column 11; a mounting frame 92 fixed to the end of the connecting plate 91 away from the column 11; a shaft 93 fixed to the side of the mounting frame 92; a sleeve 94 rotatably sleeved on the shaft 93; a first connecting rod 95, one end of which is fixedly connected to the sleeve 94; a collar 96 fixed to the end of the first connecting rod 95 away from the sleeve 94, and sleeved The ring 96 is sleeved on the steel cable 12; one end of the second connecting rod 97 is fixedly connected to the sleeve 94, and the second connecting rod 97 is coaxially arranged with the first connecting rod 95. The actuator includes: two mounting boxes 101, which are respectively fixed to the upper and lower ends of the mounting frame 92, and the two mounting boxes 101 are both arranged opposite to the end of the second connecting rod 97 away from the sleeve 94, and the two mounting boxes 101 have openings on the opposite sides; two control switches 102 are respectively installed on the two mounting boxes 101 Inside, the button of the control switch 102 extends through the through hole to the outside of the installation box 101; two controllers 103 are both installed on the side of the mounting frame 92, and the two controllers 103 are electrically connected to the two control switches 102 respectively. Since a ring 96 is sleeved on the steel cable 12, the ring 96 can be driven to move when the steel cable 12 sinks. The ring 96 is connected to the sleeve 94 through the first connecting rod 95, and the sleeve 94 is rotatably sleeved on the shaft 93. Therefore, when the ring 96 sinks with the steel cable 12, it can drive the first connecting rod 95 to rotate, so that the sleeve 94 rotates on the shaft 93. When the sleeve 94 rotates, it can drive the second connecting rod 97 to rotate upward, so that the end position of the second connecting rod 97 is lifted. In this case, the second connecting rod 97 can resist the control switch 102 at the upper end, and the control switch 102 that is pressurized and energized can make the corresponding controller 103 energized and operate, so that the controller 103 sends a control signal to the second hydraulic cylinder 71;

[0077] Two elastic shielding members are provided on the mounting frame 92, and the end of the second connecting rod 97 away from the sleeve 94 is located between the two elastic shielding members, and the elastic shielding members include: an opening 111, which is provided on the mounting frame 92; a stopper 112, which is slidably provided in the opening 111, and a slope is provided on the stopper 112, and the slope is provided opposite to the end of the second connecting rod 97 away from the sleeve 94; a bracket 113, which is fixed to the side of the mounting frame 92 and is provided opposite to the stopper 112; a through opening 114, which is provided on the bracket 113; a rod body 115, which is fixed to the side of the stopper 112, and the end of the rod body 115 away from the stopper 112 passes through the through opening Mouth 114; spring 116, one end of which is connected to the block 112, and the other end of which is connected to the bracket 113. The provision of the two elastic shielding members can prevent the second connecting rod 97 from pressing the two control switches 102 when the steel cable 12 shakes slightly, that is, when the photovoltaic panel vibrates slightly, the traction structure will not operate, which makes the traction structure only able to operate when the steel cable 12 sinks downward or bulges upward too much. In addition, when the second connecting rod 97 presses the control switch 102, the second connecting rod 97 just blocks the block 112, thereby preventing the block 112 from hindering the normal resetting of the second connecting rod 97.

[0078] The specific working principle of the present invention is as follows:

[0079] When the shock-absorbing flexible tracking photovoltaic bracket proposed by the present invention is actually used, under normal circumstances, the two steel cables 12 are in a taut state, the hood 63 is located above the two mounting plates 21, and the two mounting plates 21 are jointly fixed with a tracking mounting bracket 22, and a mounting frame 23 is provided on the tracking mounting bracket 22, and the photovoltaic panel is mounted on the mounting frame 23. The tracking mounting bracket 22 has the function of automatically tracking light, so that the photovoltaic panel can rotate with the angle of sunlight, thereby improving the power generation efficiency of the photovoltaic panel. The specific structure and working principle of the tracking mounting bracket 22 are not the innovative part of the present technical solution, and are not shown in the figure, and will not be described in detail here;

[0080] When the flexible tracking photovoltaic bracket is in use, the photovoltaic panel will shake under the action of wind. If this continues for a long time, the two steel cables 12 will be stretched, and the middle position will sink downward under the action of gravity. The two mounting plates 21 and the photovoltaic panels thereon will also sink accordingly. Furthermore, compared with the steel cable 12 in a taut and horizontal state, the end position of the steel cable 12 that has settled in the middle will also move downward. Since a ring 96 is provided on the steel cable 12, the ring 96 can be driven to move when the steel cable 12 settles. The ring 96 is connected to the sleeve 96 through the first connecting rod 95 and the sleeve 96. 4, and the sleeve 94 is rotatably sleeved on the shaft 93, so the collar 96 can drive the first connecting rod 95 to rotate when following the steel cable 12 to sink, so that the sleeve 94 rotates on the shaft 93, and when the sleeve 94 rotates, it can drive the second connecting rod 97 to rotate upward, so that the end position of the second connecting rod 97 is lifted. In this case, the second connecting rod 97 can resist the control switch 102 at the upper end, and the control switch 102 under pressure and energized can make the corresponding controller 103 energized to operate, so that the controller 103 sends a control signal to the second hydraulic cylinder 71;

[0081] When the second hydraulic cylinder 71 is in operation, its telescopic end can retract and pull the main traction rope 72. When the main traction rope 72 moves, it can pull a plurality of auxiliary traction ropes 741 through a plurality of fixing cards 73. Two branch traction ropes 742 are arranged at one end of the auxiliary traction rope 741 away from the main traction rope 72, and the two branch traction ropes 742 are respectively connected to the two mounting plates 21. Therefore, when the main traction rope 72 moves, the plurality of branch traction ropes 742 can synchronously apply an upward pulling force to the two mounting plates 21, thereby pulling the settled photovoltaic panel upward. The main traction rope 72 pulls the auxiliary traction ropes 741, and the auxiliary traction ropes 741 respectively press the auxiliary traction ropes 741 against the guide wheels. The setting of the guide wheels can avoid the wear between the auxiliary traction ropes 741 and the hood 63, thereby extending the service life of the auxiliary traction ropes 741 and ensuring the structural strength of the auxiliary traction ropes 741.

[0082] When the flexible tracking photovoltaic bracket is in use, when the wind blows toward the backlight side of the photovoltaic panel at a relatively high speed or at a specific angle, wind pressure will be generated on the backlight side of the photovoltaic panel, and wind suction will be generated on the light-receiving side. This wind suction will cause the photovoltaic panel to be subjected to an additional upward load, so that the photovoltaic panel has a tendency to move upward. In the prior art, anti-wind cables are usually used to resist the upward wind force acting on the photovoltaic panel. In addition to setting up anti-wind cables (proposed as a prior art, not shown in the figure, and not described in detail here), this solution can also use a traction structure to resist the upward wind force acting on the photovoltaic panel. Specifically, When the photovoltaic panel moves upward under the action of wind, the two mounting plates 21 will move upward accordingly. At this time, the two steel cables 12 will be deformed, and the middle position thereof will be formed into an upward convex shape. In this case, compared with the steel cable 12 in a taut and horizontal state, the end position of the upwardly protruding steel cable 12 will move upward. When the steel cable 12 is deformed, the collar 96 thereon can drive the first connecting rod 95 to move, so that the first connecting rod 95 rotates around the sleeve 94. When the sleeve 94 rotates, the second connecting rod 97 will rotate downward, so that the second connecting rod 97 abuts against the control switch 102 at the lower end.

[0083] When the control switch 102 at the lower end is pressurized and energized, the corresponding controller 103 can be energized. The energized controller 103 will send a control signal to the first hydraulic cylinder 5 and the second hydraulic cylinder 71. Specifically, the first hydraulic cylinder 5 will first operate and pull the corresponding slide 4 to move downward. When the slide 4 moves downward, the two lifting plates 61, the two vertical plates 62 and the hood 63 will also move downward. When the hood 63 moves downward, it will pass between the two mounting plates 21 and move to the bottom of the two mounting plates 21. In this case, the branch traction ropes 742 will move to the two mounting plates 2 1, further, the second hydraulic cylinder 71 operates and applies a pulling force to the main traction rope 72. As described above, when the main traction rope 72 moves, a downward pulling force can be applied to the two mounting plates 21 through a plurality of auxiliary traction ropes 741 and a plurality of branch traction ropes 742. Based on the above process, when the photovoltaic panel is blown upward by the wind, the plurality of branch traction ropes 742 can pull down the two mounting plates 21 together, which can resist the upward wind force acting on the photovoltaic panel, improve the structural strength of the photovoltaic panel, and provide double protection for the wind resistance and earthquake resistance of the photovoltaic panel in combination with the function of the wind-resistant rope;

[0084] It is worth noting that a pulley structure 744 is provided on the bottom surface of the hood 63. When the hood 63 moves downward, the two branch traction cables 742 will respectively bypass the two pulleys on the pulley structure 744. Under the action of the pulley structure 744, the two branch traction cables 742 can apply tension to the two mounting plates 21 more stably to avoid wear between the branch traction cables 742 and the hood 63. In addition, the specific control method of the two controllers 103 for the first hydraulic cylinder 5 and the second hydraulic cylinder 71 is the prior art, which is not an innovative part of the present technical solution, is not shown in the figure, and will not be described in detail here.

[0085] As for the mounting frame 92, two opposite elastic shielding members are arranged on it, and one end of the second connecting rod 97 away from the sleeve 94 extends between the two elastic shielding members. When the photovoltaic panel generates a slight vibration under the action of wind force, the steel cable 12 will also drive the sleeve 94 to rotate through the ring 96 and the first connecting rod 95, and the second connecting rod 97 will also swing accordingly. When the vibration amplitude of the steel cable 12 is within the normal range, the vibration amplitude of the steel cable 12 is relatively small, and the swing amplitude of the second connecting rod 97 is also small. In this case, the second connecting rod 97 cannot overcome the elastic force applied by the two springs 116 to the two blocks 112, that is, the second connecting rod 97 will not press the two control switches 102. When the steel cable 12 sinks downward or bulges upward by too much, that is, the posture of the photovoltaic panel is in an abnormal state, the second connecting rod 97 will not press the two control switches 102. In the normal state, the second connecting rod 97 can move to a greater extent. At this time, the second connecting rod 97 can push the inclined surface of the corresponding block 112, so that the block 112 overcomes the elastic force of the spring 116 and moves, so that the second connecting rod 97 presses the control switch 102. In summary, the setting of the two elastic shielding members can prevent the second connecting rod 97 from pressing the two control switches 102 when the steel cable 12 shakes slightly, that is, when the photovoltaic panel vibrates slightly, the traction structure will not operate, which makes the traction structure only able to operate when the steel cable 12 sinks downward or bulges upward too much. In addition, when the second connecting rod 97 presses the control switch 102, the second connecting rod 97 just blocks the block 112 to prevent the block 112 from hindering the normal resetting of the second connecting rod 97.
