Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to an automatically deployable roof photovoltaic module. Background Technology

[0002] A container-top photovoltaic (PV) module is a mobile energy device that integrates a photovoltaic power generation system onto the top of a shipping container (or similar container). It typically utilizes the container's load-bearing structure to fix solar panels to the top, and works in conjunction with an internal energy storage system, inverter, and charging station to form an independent integrated photovoltaic-energy storage-charging system. This device features high integration, mobility, and rapid deployment capabilities, and is widely used in remote area operations, emergency power supply, mobile offices, and military resupply scenarios.

[0003] Currently, most existing automatic deployable container-top photovoltaic (PV) modules employ guide rail sliding and pushing mechanisms, folding support mechanisms, or cylinder lifting mechanisms. For example, one type of retractable container PV panel's movement support uses an AC motor to drive a tensioning steel wire, which, in conjunction with a stretching guide rail, enables the lateral translation and deployment of the PV panels. Another example is a solar energy storage container PV panel with wing extensions, where the left and right wings slide and unfold within guide rail grooves on the support frame. Still other solutions utilize linear guide rails and electric push rods to achieve the translational deployment of the upper-layer PV modules.

[0004] The existing technology has the following obvious shortcomings in the implementation process: First, the deployed structure lacks rigidity and has poor wind resistance. Arrays supported by sliding guide rails or folding arms typically rely solely on the passive constraints of the guide rails or simple limiting components to maintain their shape after full deployment, lacking sufficient rigidity. When encountering strong winds or alternating loads, long-distance cantilevered photovoltaic panels are prone to significant bending deflection and vibration, potentially leading to equipment damage.

[0005] Second, the mechanical transmission is complex, and its stability is limited by the connection nodes. Some folding mechanisms have a large number of movable hinges and transmission components to meet the unfolding requirements, which leads to increased structural gaps and decreased stiffness; the folding process also causes a sharp shift in the center of gravity, resulting in additional torsional stress.

[0006] Third, there is a lack of active mechanical locking and protection mechanisms. Existing folding frames, once fully unfolded, typically rely on limit switches or simple pins for fixation, failing to provide a rigid physical lock. In strong winds, the lack of active safety measures (such as the inability to actively release stress or lock connection points) poses a risk of involuntary contraction or damage. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art by proposing an automatically deployable roof-mounted photovoltaic module.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatically deployable container-top photovoltaic module, comprising an outer limiting frame, wherein locking clips are fixedly installed at the four corners of the lower end of the outer limiting frame, and the four locking clips are engaged with the upper end of the container body; photovoltaic mounting frames are rotatably installed at both ends of the outer limiting frame; four equidistantly arranged photovoltaic panels are movably installed on the outer surface of each photovoltaic mounting frame; and a rotating support base is fixedly installed between the photovoltaic mounting frame and the outer limiting frame; a flipping drive mechanism is fixedly installed on the outer surface of the rotating support base; and a lifting mechanism is fixedly installed on the lower surface of the outer limiting frame. The container body has symmetrical fixed bases fixedly installed inside. Support frames are fixedly installed at both ends of the lower surface of the outer limiting frame. Hinged bases are fixedly installed on both sides of the lower end of each support frame. A follow-up support mechanism is fixedly installed on the upper end of the hinged base. A hanging rail is fixedly installed on the outer side of each photovoltaic mounting frame. Two symmetrical rollers are slidably installed on the upper end of the hanging rail. A main mounting bracket is fixedly installed on the opposite outer side of the hanging rail. A hinge is fixedly installed between every two adjacent photovoltaic panels on the main mounting bracket. A prestressed tempering mechanism is fixedly installed on the rear surface of the photovoltaic panel.

[0009] As a preferred technical solution of the present invention, the flipping drive mechanism includes a drive motor fixedly installed on the outer surface of the rotating support base, a drive shaft fixedly installed at the output end of the drive motor, a drive rod fixedly installed on the side of the photovoltaic mounting frame near the rotating support base, one end of the drive rod being engaged with the drive shaft, and two symmetrical hinged brackets are also provided on the outer surface of the outer limiting frame, with a follower connecting rod rotatably installed between each hinged bracket and the photovoltaic mounting frame.

[0010] As a preferred technical solution of the present invention, the follow-up support mechanism includes lower connecting rods rotatably mounted at both ends of the upper surface of the hinged base. A central connecting hinge shaft is rotatably mounted at the other end of each lower connecting rod. An upper connecting rod corresponding to the lower connecting rod is rotatably mounted at the upper end of the central connecting hinge shaft. A column connecting bracket is rotatably mounted at one end of the central connecting hinge shaft. The other end of the column connecting bracket is fixedly mounted on the outer surface of one side of the support frame.

[0011] As a preferred technical solution of the present invention, a sliding support seat is rotatably installed at the upper end of the upper connecting rod, a follower docking track seat is fixedly installed on the lower surface of the photovoltaic mounting frame, a fixed track seat is fixedly installed on the lower surface of the outer limiting frame, the follower docking track seat and the fixed track seat are engaged and both have docking grooves, and the sliding support seat is slidably installed inside the docking groove.

[0012] As a preferred technical solution of the present invention, the lower end of the main mounting bracket is engaged with a rotating shaft, a push rod is slidably mounted on one side of the main mounting bracket, symmetrical guide posts are fixedly mounted on one side surface of the push rod, a return spring is sleeved on the outer side of each guide post, and the guide posts are slidably mounted on the inner side of the main mounting bracket.

[0013] As a preferred technical solution of the present invention, the prestressed steelling mechanism includes an anchor block fixedly installed on the rear surface of the photovoltaic panel. The rear surface of the photovoltaic panel is also provided with a guide seat corresponding to the anchor block. A tension steel cable is installed through the anchor block and the guide seat. An adjusting locking block is fixedly installed on the outer surface of the tension steel cable between the anchor block and the guide seat.

[0014] As a preferred technical solution of the present invention, a sliding guide groove is provided on the upper surface of the hanging rail, and a number of equidistant connecting plates are fixedly installed between the photovoltaic mounting frame and the hanging rail. The connecting plates are L-shaped structures, and a pressure sensor is fixedly installed in the middle position of the hanging rail. The lower end of each roller is engaged with an outer fixed mounting seat, and each outer fixed mounting seat is fixedly installed on the upper surface of the photovoltaic panel.

[0015] As a preferred embodiment of the present invention, a limit switch is fixedly installed on the main mounting bracket, and the push rod is slidably installed on the inner side of the main mounting bracket, with the end of the push rod corresponding to the limit switch.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution creatively introduces the coordinated operation of a prestressed steelling mechanism and a follow-up support mechanism. Through a prestressed system composed of anchor blocks, guide seats, tension cables, and adjusting locking blocks, the pre-embedded cables are actively tightened after the photovoltaic panels are fully deployed and a pressure signal is triggered. This causes the entire photovoltaic array to produce a slight upward arc, forming an arch effect. This active prestressing compresses and solidifies the originally independent photovoltaic panels into a single rigid plane, greatly offsetting the deflection of the long-distance cantilever under its own weight. Simultaneously, combined with the rigid support effect of the connecting rods and sliding support seats engaging with the docking groove, the bending stiffness is increased several times compared to traditional flat-push structures, maintaining stability even under strong winds and alternating loads.

[0017] 2. In this solution, when the photovoltaic panel is fully flattened into position via the flipping drive mechanism's motor, drive shaft, and drive rod, the rollers on both sides move towards each other within the sliding guide groove of the hanging rail. This physically presses against the pressure sensor located in the center, which precisely triggers the prestressed steel cable tensioning. When fully folded and stored, the push rod slides into the main mounting bracket under the guidance of the guide column and return spring, engaging the limit switch to send a stop signal. This closed-loop control based on physical contact ensures that prestressing tensioning will only be initiated under the extreme condition of the array being completely flattened without any jamming or gaps.

[0018] 3. This solution employs a combined action logic of lifting columns and a tilting drive mechanism, coupled with a snap-fit ​​design between the follow-up docking rail seat and the fixed rail seat. In the stowed state, the photovoltaic panels fold via hinges and descend to below the top of the container using the lifting columns, significantly reducing the overall height during transportation and drastically minimizing the windward area, protecting the fragile solar cells from the impact of hail and strong crosswinds.

Each hinge bracket 305 is rotatably connected to the photovoltaic mounting frame 4 with a follower link 306.

[0024] The follow-up support mechanism includes lower connecting rods 202 rotatably mounted at both ends of the upper surface of the hinge base 201.

[0026] The lower end of the main mounting bracket 401 is snapped with a rotating shaft 405. A push rod 402 is slidably mounted on one side of the main mounting bracket 401. Symmetrical guide posts 404 are fixedly mounted on one side surface of the push rod 402. A reset spring 403 is sleeved on the outer side of each guide post 404. The guide posts 404 are slidably mounted on the inner side of the main mounting bracket 401.

[0027] The prestressed steelling mechanism includes an anchor block 101 fixedly installed on the rear surface of the photovoltaic panel 5. The rear surface of the photovoltaic panel 5 is also provided with a guide seat 102 corresponding to the anchor block 101. A tension steel cable 103 is installed through the anchor block 101 and the guide seat 102. An adjusting locking block 104 is fixedly installed on the outer surface of the tension steel cable 103 between the anchor block 101 and the guide seat 102.

[0028] A sliding guide groove 12 is provided on the upper surface of the hanging rail 15. Several connecting plates 9 are fixedly installed between the photovoltaic mounting frame 4 and the hanging rail 15 at equal intervals. The connecting plates 9 are L-shaped structures. A pressure sensor 10 is fixedly installed in the middle position of the hanging rail 15. The lower end of each roller 11 is engaged with an outer fixed mounting seat 13. Each outer fixed mounting seat 13 is fixedly installed on the upper surface of the photovoltaic panel 5.

[0029] A limit switch 406 is fixedly installed on the main mounting bracket 401, and a push rod 402 is slidably installed on the inner side of the main mounting bracket 401, with the end of the push rod 402 corresponding to the limit switch 406.

[0030] Working Principle: In the initial deployment phase, the system receives a deployment command, and the lifting column 6 located below the outer limiting frame 2 begins to rise vertically upwards, causing the entire outer limiting frame 2, along with the photovoltaic mounting frames 4 on both sides, to detach from the top of the container body. Simultaneously, the follow-up support mechanisms on both sides begin to work in tandem. The hinged base 201 at the bottom of the support frame 8 is subjected to force, causing the linkage group consisting of the lower connecting rod 202, the middle connecting hinge shaft 203, and the upper connecting rod 204 to gradually open, maintaining the balance during the frame's ascent. Once the lifting reaches the preset height, the flipping drive mechanism engages. The drive motor 302 outputs torque, which drives the drive rod 304 via the drive shaft 303, forcing the photovoltaic panel 5 to flip outwards around the rotating support base 301. During this process, the hinged bracket 305 and the follow-up connecting rod 306 precisely define the flipping trajectory, ensuring that the photovoltaic panel 5 smoothly transitions from a vertically folded state to a horizontal state.

[0031] As the photovoltaic panel 5 approaches a perfectly horizontal position, the components enter the precise docking stage. First, the follow-up docking track seat 208 below the photovoltaic mounting frame 4 perfectly engages with the fixed track seat 207 on the outer limiting frame 2, forming a continuous long track. Simultaneously, the sliding support seat 209 connected to the top of the upper connecting rod 204 slides smoothly into the docking groove 206, providing crucial external physical support for the horizontal mounting frame and completely changing the stress state of the traditional cantilever structure. At this time, the rollers 11 mounted on the hanging rail 15 slide towards each other within the sliding guide groove 12. When the photovoltaic array is completely flattened without any gaps, the rollers 11 on both sides precisely press against the pressure sensor 10 in the middle of the hanging rail 15. This physical hard feedback trigger signal is immediately transmitted to the control system, marking the true and accurate completion of the flattening action.

[0032] Upon receiving the pressure signal, the system immediately enters the prestressing stiffening stage. The prestressing stiffening mechanism installed on the rear surface of the photovoltaic panel 5 begins to operate. Adjusting the locking block 104 applies tension to the tension cable 103 passing through the anchor block 101 and the guide seat 102, forcing the entire row of photovoltaic panels 5 to produce an extremely small upward arc. This classic arch bridge effect transforms the originally loosely spliced ​​array into a rigid plane under overall pressure. All adjacent connection parts bear a huge positive compressive force, greatly offsetting the deflection caused by gravity and significantly improving the bending stiffness of the array under strong wind conditions. During the storage stage, the system strictly follows the sequence of depressurization before storage. The push rod 402 on the main mounting bracket 401 slides inward under the guidance of the guide post 404 and the return spring 403. When the end of the push rod 402 contacts the limit switch 406, an electrical signal is triggered. The system first releases prestress, slacks the tension cable 103, and then the sliding support seat 209 of the follow-up support mechanism disengages from the docking groove 206, releasing the external support. Next, the flipping drive mechanism reverses its rotation, folding the photovoltaic panel 5 back to a vertical position, while the lifting column 6 descends simultaneously. As the push rod 402 re-touches the limit switch 406, confirming that the photovoltaic panel 5 is fully retracted to its low position, the drive motor 302 immediately brakes and stops, causing the lifting column 6 to pull the frame back down. The entire device returns to its compact, folded state during transport, significantly reducing the windward area and achieving high safety and all-weather adaptability. The entire process relies on the physical contact of mechanical movements as the core control signal, avoiding the misjudgment risks of purely electronic program control and ensuring extremely high reliability for long-term equipment operation.
