Description

Technical Field

[0001] This utility model relates to a semi-automatic material transport device, and more particularly to a device for transporting complex mountain photovoltaic modules, belonging to the technical field of photovoltaic panel transport equipment. Background Technology

[0002] Looking at the development of the photovoltaic industry, its development in Northwest China is limited by grid integration issues, while the Central China Plain is constrained by land availability. Future development of the photovoltaic industry will likely lean towards mountainous areas. Furthermore, applying photovoltaic modules to rooftops and greenhouses is another future direction for the industry. However, material transportation is a major challenge in mountainous photovoltaic construction. Due to the terrain, large, medium, and small equipment cannot transport materials to easily accessible locations; they must be transported to suitable areas for secondary material distribution. Currently, secondary material distribution can only be done using drones and personnel, while ground material distribution relies solely on manual labor, resulting in very low efficiency. Moreover, drones operating during material distribution face significant safety risks due to overlapping operations. Ground material distribution often involves uphill and downhill work, with personnel working in both directions, further increasing safety risks.

[0003] Therefore, ziplines are used to transport photovoltaic panels. Zipline transport can directly cross mountains and ground obstacles, making it highly adaptable; it has a short transport distance, saving travel time; its structure is compact, requiring minimal construction and causing little damage to the natural landscape; it has low energy consumption and no pollution; and its investment is relatively lower than other forms of transport, with a quick return on investment. Currently, the zipline transport equipment used requires fixing the photovoltaic panels to the zipline, and most people choose to use ropes for binding. This method not only requires a lot of time for assembly and disassembly but also necessitates changing the ropes according to the size of the photovoltaic panels, which is not conducive to improving the transport efficiency of the photovoltaic panels. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a semi-automatic material transport device.

[0005] The technical solution adopted in this utility model is as follows: A semi-automatic material transport device is designed for transporting photovoltaic panels during the construction of mountain photovoltaic power stations. It can also be used to transport other materials, such as photovoltaic supports and concrete. This transport device needs to be erected between two photovoltaic module columns at different heights for easy and rapid installation and fixing. Its structure includes clamps, support rods, a sliding cable, a cage, fixed pulleys, a traction rope, and a winch. A support rod is fixed to each of the two photovoltaic module columns at different heights via clamps, providing reliable support and an erection platform. The sliding cable is installed between the two support rods, and a cage is slidably mounted on the cable, allowing the cage to slide along the cable. Photovoltaic panels are placed inside the cage for transport. The fixed pulley is installed on the photovoltaic module column located at a high position. The winch is placed on one side of the photovoltaic module column at a high position. One end of the traction rope is wound around the winch, and the other end passes through the fixed pulley and is connected to one end of the cage. The winch controls the raising and lowering of the traction rope, thereby controlling the cage to slide along the cable to transport the photovoltaic panels, etc. The cage is provided with an inner cavity for accommodating the photovoltaic panels. The photovoltaic panels can be inserted into the cage from one side. Placing the photovoltaic panels in the inner cavity of the cage can reduce damage to the photovoltaic panels and facilitate quick loading and unloading of the photovoltaic panels, thereby improving the transport efficiency.

[0006] Furthermore, the support rod is equipped with hooks, and both ends of the zipline are fixed to these hooks for quick and easy connection. Multiple hooks are arrayed along the length of the support rod, allowing for flexible and convenient adjustment of the zipline height by selecting a hook at a suitable height. The support rod also features multiple sets of mounting holes arrayed along its length, each set containing two through-holes. The fixed pulley is fixed to one set of mounting holes on the support rod using two sets of bolt assemblies. This structural design allows for simultaneous adjustment of the fixed pulley's installation height when the zipline height is adjusted, resulting in smoother traction from the traction rope. These structural features enable the transport device to adapt to a wider range of photovoltaic panel transport environments and are particularly suitable for complex mountainous installation conditions.

[0007] Furthermore, two parallel sliding cables are installed between the two support rods, and each cable is threaded onto the cage. It is understandable that when only one sliding cable is used, the cage is easily affected by external environmental factors (such as wind) during transport, causing it to sway and potentially damaging the photovoltaic panels inside. By installing two sliding cables, the cage can be limited to a certain extent, reducing its swaying, protecting the photovoltaic panels, and also preventing the transport device from colliding with the outside environment.

[0008] Furthermore, the cage includes a rectangular loading frame, with a loading port and a unloading port at each end along its length. A baffle plate is installed on the unloading port, which can open or close the unloading port. In use, the unloading port is closed at the starting point, and then photovoltaic panels are loaded into the rectangular loading frame through the loading port. After being transported to the endpoint, the unloading port is opened to unload the photovoltaic panels and then closed. This process can be repeated.

[0009] Furthermore, the baffle plate is hinged to the rectangular loading frame, and a female locking block is provided on the rectangular loading frame. A slot is formed between the female locking block and the rectangular loading frame. A male locking block is rotatably provided on the baffle plate. When the baffle plate closes the unloading port, the male locking block rotates and engages with the slot to lock the baffle plate. Through the cooperation of the female locking block and the male locking block, the unloading port can be quickly opened or closed.

[0010] Furthermore, the cage also includes a lifting base, on which the rectangular loading frame is installed. Lifting pulleys are provided at both ends of the lifting base, and the lifting pulleys slide on the cable. The structure is simple and the sliding is smooth and reliable.

[0011] Furthermore, support plates are respectively provided at both ends of the lifting base, and the support plates are arranged in pairs at each end of the lifting base. The lifting pulleys are rotatably installed between the two pairs of support plates, forming stable support for the pulleys. Two lifting pulleys are provided between the two pairs of support plates at each end of the lifting base, and two parallel sliding cables are arranged between the two support rods. The two lifting pulleys at each end of the lifting base are respectively hung on the two sliding cables.

[0012] Furthermore, the lifting base is made of a rectangular tube, with multiple lifting lugs symmetrically arranged on the front and rear sides of its lower part. The lifting lugs are fixed to the rectangular loading frame by locking bolt assemblies, allowing the rectangular loading frame to be separated from the lifting base for easy transfer, installation, and maintenance. Pull rings are provided at both ends of the lifting base, and the traction rope is connected to the pull rings. Pulling the lifting base moves the entire cage, making transportation more stable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a suspended cage for transporting photovoltaic panels, reducing damage and facilitating quick loading and unloading, thus improving transport efficiency. Furthermore, the photovoltaic panels can be easily inserted into the cage, allowing for the transport of panels of different specifications or in varying quantities (by setting a larger inner thickness for the cage), making it more convenient to use.

[0015] This utility model allows for quick and convenient loading and unloading of photovoltaic panels during transportation, and it is well-suited to accommodate different specifications and quantities of photovoltaic panels, thus improving transportation efficiency. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1

[0025] like Figure 1 As shown, a semi-automatic material transport device is mainly used for transporting photovoltaic panels during the construction of mountain photovoltaic power stations. It needs to be erected between two photovoltaic module pillars 1 at different heights. These pillars 1 are those already constructed on the mountainside but without photovoltaic supports and panels yet installed. The two pillars are typically located at different heights on the mountainside. However, even if the two photovoltaic module pillars 1 are at the same horizontal height, it does not affect the use of this transport device, and photovoltaic panels can still be transported using it.

[0026] like Figure 1-3 As shown, the transportation device in this embodiment includes a support rod 3, a zipline 4, a cage 5, and a fixed pulley 6 (with an auxiliary mounting bracket, such as...). Figure 4 As shown, using simple and conventional technology (not described in detail), a traction rope 7 and a winch 8 are used. A support rod 3 is fixed to each of the two photovoltaic module columns 1 at different heights via clamps 2. These clamps 2 are simple clamps readily available in the market, and are installed at least at the top and bottom ends and the middle of the support rod 3 for secure clamping. It should be noted that due to requirements such as agricultural-photovoltaic integration and forestry-photovoltaic integration, the photovoltaic module columns 1 are usually set relatively high, so this does not affect the erection and fixation of the support columns. A sliding cable 4 is installed between the two support rods 3, and a cage 5 is slidably mounted on the sliding cable 4. A fixed pulley 6 is installed on the photovoltaic module column 1 at the higher position. The winch 8 is placed on one side of the photovoltaic module column 1 at the higher position. One end of the traction rope 7 is wound around the winch 8, and the other end passes through the fixed pulley 6 and is connected to one end of the cage 5. The cage 5 is provided with an inner cavity for accommodating photovoltaic panels. The inner cavity is rectangular and its length is greater than two-thirds of the length of the photovoltaic panel. In use, the photovoltaic panel is inserted into the inner cavity for transportation, so it can be used to transport photovoltaic panels of different lengths. The thickness of the inner cavity is greater than the thickness of a conventional photovoltaic panel, and can even be several times the thickness of a conventional photovoltaic panel, so that multiple photovoltaic panels can be transported at the same time.

[0027] One method for connecting the sliding cable 4 to the support rod 3 is as follows: A hook 9 is provided on the support rod 3, the hook 9 forming a C-shaped hanging groove. Both ends of the sliding cable 4 are fixed to the hook 9. Alternatively, loops can be tied at both ends of the sliding cable 4, and the loops can be directly hung on the hook 9 for easy and quick connection and disconnection. Multiple hooks 9 can be arranged in an array along the length of the support rod 3. The hooks 9 can be welded to the support rod 3 for fixation. Since the installation height of the sliding cable 4 can be adjusted by hanging it on different hooks 9, the installation height of the fixed pulley 6 also needs to be easily adjustable to better pull the cage 5. For example, multiple sets of mounting holes can be arranged in an array along the length of the support rod 3, each set containing two circular holes penetrating the support rod 3. The fixed pulley 6 is fixed to one set of mounting holes on the support rod 3 by two sets of bolt assemblies.

[0028] Example 2

[0029] This embodiment is a further optimization and refinement of the structure of the cage 5 based on embodiment 1. Specifically, the cage 5 includes a rectangular loading frame 10, which is welded from rectangular tubes and forms an inner cavity to accommodate photovoltaic panels. The length of this inner cavity is greater than two-thirds of the length of the photovoltaic panel, or it can be greater than the length of the photovoltaic panel. The thickness is much greater than the thickness of the photovoltaic panel to facilitate the transportation and use of different photovoltaic panels. A loading port 11 and a unloading port 12 are respectively provided at both ends along the length of the rectangular loading frame 10. A baffle plate 13 is provided on the unloading port 12, which can open or close the unloading port 12.

[0030] One side of the baffle plate 13 is hinged to the rectangular loading frame 10. A female locking block 14 is provided on the other side of the rectangular loading frame 10 opposite to the hinged side of the baffle plate 13. A slot is formed between the female locking block 14 and the rectangular loading frame 10. A male locking block 15 is rotatably provided on the baffle plate 13. When the baffle plate 13 closes the discharge port 12, the male locking block 15 rotates and engages with the slot to lock the baffle plate 13. When it is necessary to open the discharge port 12, the male locking block 15 is pulled out from the slot and the baffle plate 13 is rotated to open the discharge port 12.

[0031] Example 3

[0032] This embodiment is a further optimization and refinement of the structure of the cage 5 based on embodiment 2, specifically as follows:

[0033] The hoisting cage 5 also includes a hoisting base 16, on which the rectangular loading frame 10 is mounted. Hoisting pulleys 17 are respectively provided at both ends of the hoisting base 16, and the hoisting pulleys 17 slide on the sliding cables 4. The connection structure between the hoisting pulleys 17 and the hoisting base 16 is as follows: support plates 18 are respectively provided at both ends of the hoisting base 16, and the support plates 18 are arranged in pairs at each end of the hoisting base 16. The hoisting pulleys 17 are rotatably mounted between the paired support plates 18. More preferably, two hoisting pulleys 17 are provided between the paired support plates 18 at each end of the hoisting base 16, and two sliding cables 4 are arranged parallel to each other between the two support rods 3. The two hoisting pulleys 17 at each end of the hoisting base 16 are respectively hung on the two sliding cables 4.

[0034] The lifting base 16 is made of a rectangular tube, and multiple lifting ear plates 19 are symmetrically arranged on the front and rear sides of its lower part. The lifting ear plates 19 are fixed to the rectangular loading frame 10 by locking bolt assembly. Pull rings 20 are respectively provided at the left and right ends of the lifting base 16, and the traction rope 7 is connected to the pull rings 20.

[0035] It should be noted that some threaded structures are not shown in the attached diagram.

[0036] In using this invention, support rods 3 are first installed on the two photovoltaic module columns 1. Then, a sliding cable 4 and a hoisting base 16 are erected between the two support rods 3. Next, a winch 8 is installed and a traction rope 7 is erected. The traction rope 7 is connected to the hoisting base 16, and then a rectangular loading frame 10 is installed on the hoisting base 16 before it can be put into use. This invention can reduce personnel input and the cost of multiple transfers, while also eliminating safety risks during multiple transfers and reducing the accident rate.

[0037] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple," "multiple roots," and "multiple groups" mean two or more. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0038] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
