[0003] For stacked access systems, if a single-panel single-motor drive is used, meaning one motor drives one photovoltaic panel, multiple motors are required, along with a control system for each motor. Due to the large number of motors and the complexity of the control system, there are drawbacks such as high cost, high failure rate, high maintenance cost, and complex technology application. The deficiencies in equipment cost, equipment control, equipment safety, equipment application environment requirements, and equipment stability increase the difficulty of promotion and application.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Option 1

[0055] This invention provides a photovoltaic panel chain drive control system, such as... Figures 1-11 As shown, the control system includes: a first track 61, a second track 62, an ejection rope 7, an ejection power mechanism 71, a spacer rope 30, and multiple power beams 50. The power beams 50 are used to support the photovoltaic panels, and the power beams 50 are connected in series. Adjacent power beams 50 are connected by the spacer ropes 30. The first track 61 and the second track 62 are arranged side-by-side, and an activity space 63 is provided between the first track 61 and the second track 62. The activity space 63 includes an extension section 631 distributed from front to back. Storage section 632, the width of which gradually increases from front to back; discharge power mechanism 71 connected to discharge rope 7, used to drive the first end of discharge rope 7 to move forward; power beam 50 arranged in activity space 63, the first end of power beam 50 connected to first track 61, the last end of power beam 50 connected to second track 62; multiple power beams 50 including first power beam 51 located at the front and last power beam 52 located at the rear, the first end of discharge rope 7 connected to first power beam 51.

[0056] In this photovoltaic panel chain drive control system, the first end of the power beam 50 can move along the first track 61, and the tail end of the power beam 50 can move along the second track 62, thus allowing the power beam 50 to move within the activity space 63. Photovoltaic panels are installed on the power beams 50, and in the storage section 632, the power beams 50 and photovoltaic panels are stacked. Power is provided by the outgoing power mechanism 71; the outgoing rope 7 pulls the first power beam 51 forward, and the tension is transmitted between adjacent power beams 50 through the spacer rope 30, thereby pulling each power beam 50 and photovoltaic panel from the storage section 632 to the unfolding section 631, whereby each power beam 50 and photovoltaic panel unfolds sequentially. This photovoltaic panel chain drive control system eliminates the need for a separate motor for each photovoltaic panel, reducing the number of motors, lowering complexity, reducing application production costs and failure rates, improving operational stability, facilitating maintenance, and promoting widespread application.

[0057] In one embodiment, the control system includes a tensioning spring 29 and a tensioning rope 41. The first end of the discharge rope 7 is connected to the first end of the tensioning spring 29, and the second end of the tensioning spring 29 is connected to the first-position power beam 51. The first end of the tensioning rope 41 is connected to the first end of the discharge rope 7, and the second end of the tensioning rope 41 is connected to the last-position power beam 52. The first end of the discharge rope 7 and the tensioning spring 29 can be locked together by a locking screw 34.

[0058] During the unloading process, the unloading rope 7 pulls each power beam 50 forward. After the first power beam 51 is in position, it is stopped and cannot continue to move. At this time, the unloading power mechanism 71 continues to pull the unloading rope 7 forward. Since the tail end of the tension spring 29 is fixed to the first power beam 51, the tension spring 29 is gradually stretched by the tension of the unloading rope 7, and at the same time pulls the tension rope 41 forward. The tension rope 41 pulls the last power beam 52 forward. The last power beam 52 pushes the power beam 50 in front to move forward. Since the first power beam 51 has been limited, each power beam 50 gradually approaches, achieving tightening.

[0059] During the unloading process, the unloading rope 7 provides forward tension, first pulling the first power beam 51 through the tightening spring 29, and then pulling each power beam 50 through the fixed distance rope 30 to achieve deployment; after the first power beam 51 is in place, the unloading rope 7 still provides forward tension, pulling the last power beam 52 through the tightening rope 41, and pushing each power beam 50 on the front side to achieve tightening.

[0060] The distance rope 30 can be relatively long. During the unfolding process of the power beams 50, the tension is transmitted between adjacent power beams 50 through the distance rope 30, and a gap is left between adjacent power beams 50. The power beams 50 connected in series are stacked in the storage section 632. The reserved gaps facilitate the smooth movement of each power beam 50 from the storage section 632 to the unfolding section 631. Specifically, a stroke end block 5 is set at the front. The first power beam 51 is stopped from moving forward after it abuts against the stroke end block 5. During the unfolding process, mechanical movement gaps are maintained between the power beams 50. After unfolding, the tension spring 29 stretches and drives the tensioning line to tighten each power beam 50 for tightening.

[0061] Furthermore, such as Figure 5 and Figure 6As shown, the first end of the first power beam 51 is provided with a locking structure 36. The tail end of the tension spring 29 is fixed to the tail end of the first power beam 51. The delivery rope 7 passes through the locking structure 36, requiring the delivery rope 7 to always pass through the locking structure 36. This allows the tension spring 29 to extend and retract between its tail end fixed point and the locking structure 36, limiting the direction of extension and retraction of the tension spring 29, which helps improve the stability of the movement of the tension spring 29 and the tension rope 41. Specifically, the locking structure 36 can be a sleeve or ring fixed to the first power beam 51, through which the delivery rope 7 passes. Preferably, as shown... Figure 6 As shown, the first end of the fixed-distance rope 30 is positioned between the tail end of the tensioning spring 29 and the locking structure 36, which helps to ensure the smoothness of the unfolding and collecting movements.

[0062] In one embodiment, the control system includes an ejection tension wheel 1, which is located on the front side of the first track 61. An ejection rope 7 is wound around the ejection tension wheel 1, and the ejection tension wheel 1 guides the ejection rope 7 so that the first end of the ejection rope 7 applies tension to the power beam 50 in the forward direction.

[0063] Furthermore, the ejection tension wheel 1 is movable in the front-to-back direction; the control system includes a tension spring 3, which is connected to the ejection tension wheel 1 to apply a forward pulling force to the ejection tension wheel 1. The ejection tension wheel 1 remains balanced under the action of the tension force of the tension spring 3 and the tension force of the ejection rope 7. Specifically, the ejection tension wheel 1 is mounted on a tension wheel track, which is arranged in the front-to-back direction.

[0064] like Figure 5 As shown, the control system includes an overtravel micro-motion mechanical safety switch 4, which is located behind the discharge tensioning wheel 1. When the tension of the discharge rope 7 on the power beam 50 increases, the tension of the discharge rope 7 on the discharge tensioning wheel 1 also increases accordingly. The tension of the discharge rope 7 pulls the discharge tensioning wheel 1 backward, approaching the overtravel micro-motion mechanical safety switch 4. When the tension of the discharge rope 7 is too great, the discharge tensioning wheel 1 will be pulled to collide with the overtravel micro-motion mechanical safety switch 4, triggering the overtravel micro-motion mechanical safety switch 4. After receiving the signal, the control device controls the discharge power mechanism 71 to stop, thereby avoiding equipment damage due to overload and ensuring equipment safety. The discharge tensioning wheel 1 and the overtravel micro-motion mechanical safety switch 4 form the discharge safety switch unit 2. Figure 2 As shown, the control system includes an outbound position signal line 25 and a return position signal line 28.

[0065] In one embodiment, the control system includes a return rope 32 and a return power mechanism 72. The return power mechanism 72 is connected to the return rope 32 and is used to drive the first end of the return rope 32 to move backward. The first end of the return rope 32 is connected to the first and second power beams 51. During return, the return power mechanism 72 drives the return rope 32 to move backward, the return rope 32 pulls the first and second power beams 51 to move backward, and pushes each power beam 50 backward in sequence, so that the power beams 50 and the photovoltaic panels return to the warehouse in sequence.

[0066] Furthermore, the control system includes a spare tension rope 221 and a take-up reel 22. One end of the spare tension rope 221 is connected to the end-position power beam 52, and the other end is connected to the take-up reel 22. During retraction, the take-up reel 22 simultaneously actuates, pulling the tension rope 41 back into the compartment via the spare tension rope 221. The take-up reel 22 can be a self-retracting elastic take-up reel.

[0067] like Figure 6 and Figure 7 As shown, the tightening rope 41 has one end connected to the locking screw 34 and the other end connected to the final locking structure 371. It passes through the ring on the first and second power beam 51 and then through the remaining tightening ring 37 before the locking point of the final locking structure 371. Figure 7 and Figure 9 As shown, the residual tightening ring 37 is connected to the self-retracting elastic retractor 22 via the residual tightening rope 221. When the retraction action occurs, the self-retracting elastic retractor 22 begins to tighten and pull the tightening rope 41 through the residual tightening rope 221 and the residual tightening ring 37. Figure 9 As shown, the remaining tension rope 221 passes through the self-retracting elastic retractor limiting mechanism 23.

[0068] In one embodiment, the outgoing power mechanism 71 and the returning power mechanism 72 are powered by the same power mechanism 70, i.e., the same power mechanism 70 provides power to the outgoing rope 7 and the returning rope 32, further reducing the number of electric motors, lowering application production costs and failure rates, and improving operational stability. Figure 9 As shown, the outbound rope 7 is connected to the surplus weight tension wheel 13, and the surplus weight tension wheel 13 is connected to the counterweight 15; the return rope 32 is connected to the surplus weight tension wheel 18, and the surplus weight tension wheel 13 is connected to the counterweight 17.

[0069] In one embodiment, the power mechanism 70 includes a motor unit 20, an outbound winding wheel 19, and a return winding wheel 21. Both the outbound winding wheel 19 and the return winding wheel 21 are mounted on the output shaft of the motor unit 20. When the output shaft rotates forward, it pulls the outbound rope 7 and simultaneously retracts the return rope 32; when the output shaft rotates in reverse, it pulls the return rope 32 and simultaneously retracts the outbound rope 7. Specifically, the motor unit 20 includes a motor and a reducer. This control system enables single-motor chain-driven inbound and outbound operation. The motor is preferably a motor with controllable speed regulation, reversing, and alarm functions. The motor is electrically connected to the controller 26 via a control cable 24, and the controller 26 is connected to a power supply line 27.

[0070] like Figure 9 As shown, the control system includes a return tension wheel. The installation method of the return tension wheel and the connection method between the return tension wheel and the return rope 32 are basically the same as the installation method of the exit tension wheel 1 and the connection method between the exit tension wheel 1 and the exit rope 7, and will not be described again here. The return tension wheel and the overtravel micro-motion mechanical safety switch form a return safety switch unit 16.

[0071] The outbound rope 7 and the return rope 32 pass through multiple guide mechanisms 6 to be guided and arranged. The guide mechanism 6 can be a guide wheel or a ring. Figure 5 As shown, the power beam 50 is provided with hinge mounting holes 33.

[0072] like Figure 2 As shown, the control system includes a proximity sensor switch 8, a normally closed proximity sensor switch 10, and a normally closed overtravel micro-motion mechanical safety switch 11, which are used to detect the return and exit positions of the power beam 50.

[0073] During the exit process, the equipment stops for protection when the last power beam and photovoltaic panel touch the proximity sensor 8 used to detect the exit position. If the proximity sensor 8 fails, the exit rope continues to exit, causing the exit tension wheel to extend and touch the overtravel micro-motion mechanical safety switch 4, stopping the equipment for protection. Conversely, if any obstruction or jamming occurs during the exit process, the exit rope continues to exit, causing the exit tension wheel to extend and touch the overtravel micro-motion mechanical safety switch 4, stopping the equipment for protection. During the return process, the equipment stops for protection when the last power beam and photovoltaic panel touch the normally closed proximity sensor 10 used to detect the return position. If the normally closed proximity sensor 10 fails, the normally closed overtravel micro-motion mechanical safety switch 11 activates, stopping the equipment for protection. If any obstruction or jamming occurs during the return-to-hoarding operation, but the return-to-hoarding rope continues to return to the hoard, the return-to-hoarding tension wheel will extend and touch the overtravel micro-motion mechanical safety switch, triggering the return-to-hoarding safety switch unit 16, and the equipment will stop operating for protection.

[0074] Figures 1-3 The process of ejecting the power beam from the storage compartment is illustrated. The ejection operation steps of this photovoltaic panel chain drive control system include:

[0075] The controller controls the motor to rotate forward, which drives the exit winding wheel to rotate forward. Through the exit rope, the remaining weight tension wheel, various guide mechanisms and the exit tension wheel, and the tensioning spring 29, the first power beam is pulled. All power beams are connected to each other through fixed-distance ropes. When the first power beam is pulled out of the warehouse by the exit rope, all power beams will exit the warehouse in sequence.

[0076] After all the power beams 50 exit the chamber in sequence, the first power beam 50 will collide with the top block 5 at the end of its travel. The exit rope 7 will continue to perform the exit action. At this time, the tension spring 29 will continue to extend, thereby pulling the tension rope 41. Since the other end of the tension rope 41 is connected to the last power beam 50, the spacing between all the power beams 50 will be tightened. When the last power beam 50 touches the proximity sensor switch 8, the photovoltaic panel exit is completed and reaches the predetermined position, and the exit extension is completed.

[0077] If the proximity sensor switch 8 fails due to other reasons, and the exit rope 7 continues to exit, it will cause damage to the equipment. If the exit rope 7 continues to tighten, the tension spring 3 will activate, and the exit rope 7 will pull the tension wheel. The tension spring 3 will extend within the spring's elastic range, and the exit tension wheel will extend and touch the overtravel micro-motion mechanical safety switch 4, forcibly stopping the equipment for protection.

[0078] The steps for returning the goods to the warehouse include:

[0079] The controller 26 controls the motor to reverse, which drives the return winding wheel 21 to reverse, pulling the return rope 32 to move. The return rope 32 is connected to the first power beam 50. When the return rope 32 moves, the first power beam 50 returns to its position, generating a return force that pushes the second, third, fourth, and fifth power beams back to their positions. When the power beams encounter the normally closed proximity sensor 10 during their return movement, the return of the power beam 50 is complete.

[0080] If the normally closed proximity sensor 10 does not stop operating, it will overshoot the limit and impact the normally closed overtravel micro-motion mechanical safety switch 11, thus stopping the operation. If any jamming occurs in the return rope 32 during the return movement of the power beam 50, the return rope 32 will be continuously tightened, causing the return tensioning wheel to collide with the return safety switch unit 16, which is coupled with the return tensioning wheel, to forcibly cut off power and prevent secondary damage.

[0081] Through this photovoltaic panel chain drive control system, the power beam 50 is used to control the entry and exit of the photovoltaic panel in the warehouse, ensuring its safety, stability, low cost, and low failure rate. This effectively reduces the application and production costs, facilitates maintenance, and can be widely promoted and applied in the market. It has the following beneficial effects: (1) The photovoltaic panel is controlled by a low-cost and highly stable safety management system through the electric motor and the steel wire ropes such as the exit rope 7 and the return rope 32; (2) In photovoltaic power generation, the photovoltaic panel can be extended or retracted in the external environment to ensure that the damage to the photovoltaic panel caused by severe weather is reduced to zero.

[0082] Figures 1-4 The photovoltaic panel chain drive control system shown includes 5 drive beams, each corresponding to 5 photovoltaic panels. However, the number of drive beams and the number of photovoltaic panels installed in this photovoltaic panel chain drive control system are not limited and can be configured according to the actual application dimensions.
