Description

Technical Field

[0001] This invention relates to a suspended transport device for transporting photovoltaic panels when installing photovoltaic power generation devices on steep hillsides, and particularly to a non-powered suspended transport system and method for transporting photovoltaic panels to different locations on steep hillsides for installation. Background Technology

[0002] During the on-site installation of photovoltaic power generation systems in mountainous areas, situations sometimes arise where photovoltaic modules need to be installed on trapezoidal steps at different heights on steep slopes. The modules need to be transported from the mountaintop to different areas on the slope for installation. Current technology involves manually transporting the photovoltaic panels. However, due to the steep slopes, the breakage rate of the panels during transport is high. Furthermore, the large installation area requires multiple lifting and lowering operations, and the loose stones underfoot and the low friction between shoes and gravel on the slope easily cause workers to slip and fall, frequently resulting in panel breakage. Additionally, each photovoltaic panel weighs approximately 35 kilograms, requiring two people to carry it horizontally. However, in practice, for convenience, workers often carry the panels on their backs by a single person, further contributing to the high breakage rate. Therefore, developing a device suitable for safely transporting photovoltaic panels on steep slopes has become an urgent problem to solve on-site. Summary of the Invention

[0003] This invention provides a non-powered suspension method for transporting photovoltaic power generation modules on steep mountain slopes, solving the technical problem of how to develop a method suitable for safely transporting photovoltaic panels to the site for installation in mountainous environments.

[0004] The present invention solves the above technical problems through the following technical solutions: The overall concept of this invention is as follows: This invention utilizes the elevation difference of a hillside and leverages the gravitational potential energy of the photovoltaic panels being transported to different installation areas on the hillside without requiring external power. Specifically, it fully utilizes the steep hillside terrain by installing hilltop pillars at the top of the hill. Holes are drilled manually at pre-selected locations to install the hilltop pillars. Two bottom pillars are installed at the bottom of the ditch. A V-shaped steel cable is strung between the tops of the three pillars, serving as the track for the mobile trolleys. Two identical mobile trolleys are constructed using channel steel (or angle steel). Two axles are installed between the two uprights of the channel steel, and a roller is installed on each axle. The roller's surface has a concave groove, allowing it to ride on the steel cable. The trolleys are positioned at the top of the hillside. A fixed pulley is installed on the column. One channel steel trolley is placed on a steel wire rope from the top of the slope to the bottom of the ditch, and another channel steel trolley is placed on another steel wire rope from the top of the slope to the bottom of the ditch. A nylon rope (or hemp rope) is installed between the two channel steel trolleys to connect them. The middle of the nylon rope is wrapped around the fixed pulley on the column at the top of the slope. A counterweight is suspended on one of the channel steel trolleys, and a photovoltaic panel is suspended on the other channel steel trolley. The potential energy generated by the weight difference between the counterweight and the suspended photovoltaic panel enables the two channel steel trolleys to move automatically up and down between the top of the slope and the bottom of the ditch, thereby completing the transportation of the photovoltaic panel on the hillside. To prevent the photovoltaic panel from being damaged due to weight imbalance after loading and unloading, hemp ropes are tied to both ends of the trolleys to assist in braking the photovoltaic panel transportation trolleys.

[0005] A non-powered suspended transport system for installing photovoltaic power generation modules on steep hillsides includes a column at the top of the slope, a first column at the bottom of the ravine, a second column at the bottom of the ravine, photovoltaic panels to be transported, and counterweights. The photovoltaic panels to be transported are positioned at the top of the slope. A track wire rope connection lug is fixedly installed at the top of the column at the top of the slope. A track wire rope starting connection lug is installed at the top of the first column at the bottom of the ravine, and a track wire rope ending connection lug is installed at the top of the second column at the bottom of the ravine. A track wire rope is connected to the starting connection lug. The other end of the track wire rope is arranged from bottom to top along the hillside, passes through the track wire rope connection lug, and then is arranged from top to bottom along the hillside, connecting to the ending connection lug, forming two aerial inclined steel wire rope tracks suspended above the hillside. A fixed pulley connection lug is fixedly installed on the column at the top of the slope above the track wire rope connection lug, and a fixed pulley is connected to the fixed pulley connection lug. A first two-wheeled trolley is movably mounted on the steel wire rope between the first column at the bottom of the ditch and the first column at the top of the slope. The two wheels of the first two-wheeled trolley rest on the steel wire rope, and a bundled photovoltaic panel is suspended on the first two-wheeled trolley. A second two-wheeled trolley is movably mounted on the steel wire rope between the column at the top of the slope and the second column at the bottom of the ditch. The two wheels of the second two-wheeled trolley rest on the steel wire rope, and a bundled counterweight plate is suspended on the second two-wheeled trolley. A two-carriage connecting nylon rope is connected to the upper end of the first two-wheeled trolley. The other end of the two-carriage connecting nylon rope is first arranged from bottom to top along the hillside, passes around a fixed pulley, and then is arranged from top to bottom along the hillside before connecting to the upper end of the second two-wheeled trolley. A first control nylon rope is set between the inclined lower end of the first two-wheeled trolley and the first column at the bottom of the ditch, and a second control nylon rope is set between the lower end of the second two-wheeled trolley and the second column at the bottom of the ditch.

[0006] The structure of the first two-wheeled mobile trolley is exactly the same as that of the second two-wheeled mobile trolley. The body of the first two-wheeled mobile trolley is a section of channel steel. An upper travel wheel axle and a lower travel wheel axle are respectively installed in the channel steel section. An upper travel wheel is installed on the upper travel wheel axle. An annular groove is provided on the wheel surface of the upper travel wheel. The upper travel wheel rides on the track wire rope through the annular groove. U-shaped lifting parts are hinged to the two outer ends of the upper travel wheel axle that extend to the outside of the channel steel section. A lifting hook is connected to the lower end of the U-shaped lifting part. The upper end of the photovoltaic panel is tied with a rope and connected to a hook. A lower traveling wheel is installed on the lower traveling wheel axle, and an annular groove is provided on the wheel surface of the lower traveling wheel. The lower traveling wheel rides on the track wire rope through the annular groove. A second U-shaped lifting member is hinged to the two outer ends of the lower traveling wheel axle that extends to the outside of a section of channel steel body. A second hook is connected to the lower end of the second U-shaped lifting member. The lower end of the photovoltaic panel is tied with a rope and connected to the second hook. The photovoltaic panel is suspended on the first two-wheeled moving trolley by the upper end tied with the rope and the lower end tied with the rope.

[0007] A loading point for photovoltaic panels is set at the top of the slope, below the pillar at the top of the slope.

[0008] A method for transporting photovoltaic power generation modules on a steep hillside without power using a suspended system includes the following steps: The first step is to determine the number of photovoltaic panels to be transported, which are suspended on the first two-wheeled trolley, based on the weight of the counterweight, so that the weight of these photovoltaic panels is greater than the weight of the counterweight. The second step involves suspending the photovoltaic panels, whose number was determined in the first step, onto the first two-wheeled mobile trolley using upper and lower binding ropes. The third step involves pulling and releasing the first and second control nylon ropes. The first two-wheeled trolley moves downward along the track wire rope between the top pillar and the first pillar at the bottom of the ditch. At the same time, the second two-wheeled trolley moves upward along the track wire rope between the top pillar and the second pillar at the bottom of the ditch, pulled by the first two-wheeled trolley. During this process, the second control nylon rope is released towards the top of the slope, and the first control nylon rope is received towards the bottom of the ditch. Step 4: When the first two-wheeled moving trolley moves to the pre-unloading position, simultaneously stop retracting the first and second control nylon ropes and tighten them. Under the simultaneous tension of the first and second control nylon ropes, the first and second two-wheeled moving trolleys stop moving at the same time. Step 5: After the photovoltaic panels to be transported are unloaded at the pre-unloading position, the first and second control nylon ropes are simultaneously released. Under the influence of the gravity component of the counterweight, the second two-wheeled moving trolley moves downward along the track wire rope between the top column of the slope and the second column of the ditch. Under the traction of the second two-wheeled moving trolley, the empty first two-wheeled moving trolley moves upward along the track wire rope between the top column of the slope and the first column of the ditch. At the same time, the second control nylon rope is received towards the bottom of the ditch, and the first control nylon rope is released towards the top of the slope. Step 6: When the first two-wheeled moving trolley moves to the loading position, simultaneously stop retracting the first and second control nylon ropes and tighten them. Under the simultaneous tension of the first and second control nylon ropes, the first and second two-wheeled moving trolleys stop moving at the same time. Step 7: Repeat steps 2 through 6 to transport the photovoltaic panels to the next pre-unloading position in sequence.

[0009] This invention utilizes steel columns fixed to mountaintops and valley bottoms by steel wire ropes. A counterweight at one end and a photovoltaic panel at the other, along with the height difference between the mountaintop and valley bottom, convert the potential energy of the height difference into kinetic energy. By disrupting the balance between the counterweight and the photovoltaic panel, and utilizing their weight difference, the photovoltaic panel is moved from the mountaintop to the valley, thus improving transportation efficiency and reducing damage rate.
