[0017] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] According to an embodiment of the present invention, a high-slope photovoltaic module transportation system includes at least two telescopic supports, a guide rail mechanism, and a first hoisting structure. Each telescopic support includes a fixed support 1 and an adjustable support 2. The fixed support 1 is fixedly connected to the ground, and at least a portion of the adjustable support 2 enters the fixed support 1 and is slidably connected to it. A fixing member passes through the fixed support 1 and connects to the adjustable support 2 to fix the adjustable support 2. The fixed supports 1 of the two telescopic supports are spaced a certain distance apart and have a height difference. The guide rail mechanism includes a first movable pulley 3, a track cable 4, and multiple eccentric wheels 6. At least two eccentric wheels 6 are arranged on each adjustable support 2. The center wheel 6 and the track cable 4 pass through the two eccentric wheels 6 of the two telescopic supports to form a closed parallelogram guide rail. The first movable pulley is arranged on the track cable 4. The hoisting structure includes a hoisting beam 7, a winch 9 and a fixed pulley 8. The hoisting beam 7 is connected to the first movable pulley 3. The end of the hoisting beam 7 is equipped with a transport hook for fixing the photovoltaic module. The first end of the transmission cable 5 is connected to the first movable pulley 3 or the hoisting beam 7. The second end of the transmission cable 5 passes around the fixed pulley 8 and is connected to the winch 9. The fixed pulley 8 is arranged on the fixed support 1 of the telescopic support located at a high position. The winch 9 is fixed to the fixed support 1 or the ground. The telescopic support frame is height-adjustable to adapt to steep slopes. The fixed support frame 1 is secured to the ground via a concrete foundation. The adjustable support frame 2 is inserted into the fixed support frame 1, and the fixing element can be a bolt. By changing the adjustment hole 13 into which the bolt is inserted, the position of the adjustable support frame 2 is altered, thereby adjusting its height. This, in turn, changes the position and tilt angle of the eccentric wheel 6 and the track cable 4, thus adjusting the cable's tilt angle. The horizontal distance between the two fixed supports 1 is determined based on the length of the steep slope to ensure the guide rail mechanism forms a gently sloping track, preventing severe shaking during component transportation due to sudden changes in slope.

[0019] Four eccentric wheels 6 on the two adjusting supports 2 form four points of a parallelogram. The track cable 4 passes around these four points to form a closed parallelogram guide rail. The length of the lifting beam 7 is related to the size of the photovoltaic module. The lifting beam 7 lifts the photovoltaic module via hooks. The winch 9 pulls the lifting beam 7 and the movable pulley along the track cable 4 by winding the transmission cable 5. The fixed pulley 8 changes the direction of movement of the transmission cable 5. The adjusting supports 2 can flexibly adjust their height according to the actual slope of the steep slope, eliminating the need for customized supports for different slopes and reducing the amount of foundation excavation.

[0020] In some embodiments, a buffer structure is also included, which includes a spring buffer 10, a limiting block 11, and a pad 12. The spring buffer 10 is located below the eccentric wheel 6 and connected to the adjusting bracket 2. The limiting block 11 is arranged at one end of the spring buffer 10 away from the adjusting bracket 2, and the pad 12 is arranged at both ends of the lifting beam 7.

[0021] Specifically, the buffer structure reduces the impact of the lifting beam 7 on the adjusting bracket 2, preventing damage to the equipment. It also reduces vibration, preventing the hooked photovoltaic modules from falling off. The spring buffer 10 is a cylindrical helical compression spring used to absorb impact. Fixed to the adjusting bracket 2 and positioned below the eccentric wheel 6, it ensures interception of the lifting beam 7. The limiting block 11, located at the end of the spring buffer 10, absorbs impact and protects the spring. It also extends the overall length of the buffer structure, allowing for earlier contact with the lifting beam 7 and reducing impact. The pad 12 can be made of rubber or polyurethane. The pad 12 prevents the lifting beam 7 from directly impacting the adjusting bracket 2 when it shifts, absorbing some impact. Furthermore, the cross-sectional area of ​​the pad 12 can be larger than that of the lifting beam 7, reducing the impact of the lifting beam 7 on the spring buffer 10 and facilitating alignment between the pad 12 and the limiting block 11.

[0022] In some embodiments, a plurality of adjustment holes 13 are provided at equal intervals along the height direction on the fixed bracket 1, and the fixing member passes through the adjustment holes 13 and abuts against the adjustment bracket 2 to fix the adjustment bracket 2.

[0023] Specifically, the adjustment hole 13 is positioned to avoid the stress concentration area of ​​the fixed bracket 1. After the bolt passes through the adjustment hole 13, its end abuts tightly against the outer wall of the adjustment bracket 2. To enhance the fixing effect, anti-slip textures are provided on the outer wall of the adjustment bracket 2 at the corresponding abutment position to increase friction. Alternatively, threaded holes can be provided on the outer wall of the adjustment bracket 2 for engagement with the bolt. Optionally, scale lines are provided on the sides of the adjustment bracket 2 and the fixed bracket 1. During installation, the adjustment bracket 2 is first inserted into the fixed bracket 1 to the target height. The height position is confirmed by the scale lines on the side of the fixed bracket 1. Then, the fixing bolts are passed through the adjustment holes 13 on both sides to complete the fixing of the adjustment bracket 2. No complicated height measurement and cutting are required during installation. Only the adjustment hole 13 needs to be selected according to the preset scale lines, and 1-2 workers can complete the installation of the fixing component. The adjustable bracket 2 can adapt to different steep slope height differences without replacing the fixed bracket 1.

[0024] In some embodiments, a second hoisting structure is also included. The second hoisting structure includes a second movable pulley, a connecting block, and a second crossbeam. The movable pulley is arranged on the track cable 4. The second movable pulley is connected to the second crossbeam through the connecting block. The first end of the transmission cable 5 is connected to the connecting block. The second movable pulley is arranged on the track cable 4, which is parallel to the first movable pulley 3, on a parallelogram guide rail. The second movable pulley and the first movable pulley 3 are spaced a certain distance apart.

[0025] Specifically, the second lifting structure and the first lifting structure are each located on one side of a parallelogram, with a height difference between them. Depending on the terrain, one or both can be used simultaneously. Using both simultaneously improves transportation efficiency, allowing for synchronous transport and increasing the capacity of a single trip. When used individually, adjustments can be made flexibly according to the terrain. Separating the two lifting structures reduces the load on the steel cables and extends their service life. The second lifting mechanism features a redundant design, allowing transport to continue even if one lifting mechanism fails. The second and first lifting structures can share a single winch.

[0026] In some embodiments, a self-locking structure is also included, which includes a first hook 14 and a second hook 15. The first hook 14 is located on the fixed bracket 1 of the telescopic bracket at a high position, and the second hook 15 is located on the movable pulley. The second hook 15 can be hooked with the first hook 14.

[0027] Specifically, two hooks are respectively arranged on the fixed bracket 1 and the movable pulley. When the hoisting mechanism is not in use, the movable pulley can be temporarily fixed by hooking it with the first hook 14 via the second hook 15, preventing the movable pulley from moving and damaging the equipment under the influence of weather conditions. The second hook 15 can be arranged on both sides of the movable pulley, so that the movable pulley can be locked in any direction, reducing the involvement of the winch 9. The openings of the first hook 14 and the second hook 15 can be opened and closed by motor control to achieve free locking.

[0028] In some embodiments, the spreader beam 7 includes a first crossbar and a second crossbar, the first crossbar partially entering the second crossbar and being movable relative to the second crossbar to change the length of the spreader beam 7.

[0029] Specifically, the first and second crossbars form a telescopic structure, allowing for adaptation to photovoltaic modules of different sizes by changing the length of the lifting beam 7. A locking bolt is installed on the second crossbar, which passes through the second crossbar and abuts against the first crossbar for fixation. Alternatively, a threaded hole is provided on the first crossbar, and the locking bolt passes through the second crossbar and enters the threaded hole for threaded connection and fixation. The beam size is compatible with all mainstream photovoltaic module sizes, eliminating the need for custom-made beams for different module sizes and reducing equipment costs. When a project uses multiple module sizes simultaneously, there is no need to disassemble and replace the beam; it can be adapted simply by telescopic adjustment, reducing project delays caused by equipment replacement.

[0030] In some embodiments, the lifting beam 7 includes two crossbars connected by a connecting rod, the crossbars being parallel to the adjacent crossbars, and a movable pulley connected to the connecting rod.

[0031] Specifically, the two parallel crossbars widen the span of the lifting beam 7, and hooks are arranged at the ends of both crossbars to allow for the mounting of more photovoltaic modules. The width can be adjusted by changing the position of the two crossbars on the connecting rod. The span of the lifting beam 7 has greater structural strength and distributes the load to avoid local overload. Damage to a single crossbar will not affect the transport, reducing delays caused by replacement work.

[0032] In some embodiments, the two eccentric wheels 6 on the adjusting bracket 2 are spaced a certain distance apart. The eccentric wheels 6 are connected to the fixed block through a connecting rod. The fixed block is detachably connected to the adjusting bracket 2. The connecting rod is threadedly connected to the fixed block.

[0033] Specifically, the distance between the two eccentric wheels 6 determines the distance between the upper and lower rail cables 4 on the parallelogram guide rail, i.e., the distance between the first and second lifting mechanisms. By changing the depth of the connecting rod entering the fixed block, the distance between the eccentric wheel 6 and the adjusting bracket 2 can be changed, further optimizing the inclination angle of the parallelogram guide rail and adjusting the force on the adjusting bracket 2. This adjusts for errors during construction and improves accuracy. When the lifting beam 7 triggers the buffer, the rail cable 4 will generate an instantaneous impact load. The eccentric wheel 6, through the connecting rod and the adjusting bracket 2, shares the impact, preventing displacement of the eccentric wheel 6 due to excessive local force, and also correcting any misaligned eccentric wheel 6.

[0034] In some embodiments, a tension sensor and a wind speed sensor are also included. The tension sensor is arranged on the adjusting bracket 2 and the winch 9 to detect the tension of the track cable 4 and the transmission cable 5, respectively. The wind speed sensor is arranged at the end of the adjusting bracket 2.

[0035] Specifically, when abnormal tension is detected, the winch 9 can be paused to protect equipment and personnel safety, the status of the fixed support 1 and the adjusting support can be assessed in a timely manner, and a warning can be issued to stop hoisting operations and minimize losses. When the wind speed sensor detects abnormal wind speed, it can send a signal to the winch 9 to stop its operation, protecting the equipment. The moving pulley is self-locking to the fixed support 1 through a self-locking structure to prevent equipment damage. Personnel can use sensors to determine the type of equipment malfunction and carry the equipment for targeted repairs, improving maintenance efficiency.

[0036] In some embodiments, support blocks are provided on both sides of the fixed bracket 1, and the support blocks are fixedly connected to the ground.

[0037] Specifically, the two support blocks arranged on both sides of the fixed bracket 1 form a triangular force distribution, making the fixed bracket 1 more stable. The symmetrical arrangement of the support blocks on both sides of the fixed bracket 1 utilizes the component of gravity to further enhance the anti-overturning ability and limit the lateral displacement of the fixed bracket 1. The support blocks covering the ground can reduce the erosion of the soil by rainwater and protect the stability of the fixed bracket 1.
