[0042] The technical solution of this application and how the technical solution of this application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the drawings.

[0043] Please refer to Figures 1 to 3 , this application provides a transportation device, including a plate body 100, a back strap 200, a clamping assembly 300 and an adjusting mechanism.

[0044] A receiving seat 400 is provided at the bottom of the plate body 100, and the back strap 200 is connected to the plate body 100.

[0045] The plate body 100 serves as the main body of the transportation device and plays a supporting role for the photovoltaic module during transportation. The receiving seat 400 provided at the bottom of the plate body 100 supports the bottom of the photovoltaic module and stabilizes the photovoltaic module to reduce shaking during transportation. The back strap 200 is fixed to one side of the plate body 100 so that the transportation personnel can carry the photovoltaic module on the plate body 100 on their backs. It can be understood that when the transportation personnel carry the photovoltaic module on their backs, the photovoltaic module is located on the side of the plate body 100 facing away from the back strap 200.

[0046] Exemplarily, the plate body 100 is made of a high-strength lightweight material to ensure the load-bearing capacity while reducing the overall weight and facilitating carrying. The back strap 200 adopts an ergonomic design, making the operator more comfortable when carrying it on the back, so that good balance and stability can be maintained in a steep environment, such as a rugged mountain road.

[0047] The clamping assembly 300 includes a first clamping member 310 and a second clamping member 320 which are oppositely arranged. A first mounting groove 510 is provided on one side of the plate body 100, and a second mounting groove 520 is provided on the other side of the plate body 100. The first clamping member 310 is movably arranged in the first mounting groove 510, and the second clamping member 320 is movably arranged in the second mounting groove 520.

[0048] The clamping assembly 300 can clamp the photovoltaic module to fix the photovoltaic module on the plate body 100. A limiting space is formed among the plate body 100, the first clamping member 310, the second clamping member 320 and the receiving seat 400. The distance between the first clamping member 310 and the second clamping member 320 can be adjusted movably to adapt to photovoltaic modules or other goods of different sizes and shapes.

[0049] The adjusting mechanism drives the first clamping member 310 to move in the first mounting groove 510 and drives the second clamping member 320 to move in the second mounting groove 520, so that the first clamping member 310 and the second clamping member 320 approach and move away from each other.

[0050] The adjusting mechanism can drive the first clamping member 310 to slide longitudinally in the first mounting groove 510 independently or synchronously, and drive the corresponding movement of the second clamping member 320 in the second mounting groove 520. Through the adjusting mechanism, it is beneficial to improve the loading flexibility and ensure the stable fixation of goods in complex terrains, avoiding the falling off or damage of goods caused by bumps during the handling process.

[0051] In practical applications, according to the size of the photovoltaic module, the transporter first adjusts the distance between the two clamping members to a suitable position through the adjusting mechanism, and then places goods such as the photovoltaic module on the receiving seat 400 of the plate body 100. Then, through the adjusting mechanism, the first clamping member 310 and the second clamping member 320 are made to approach each other until the photovoltaic module is clamped. Subsequently, the transporter carries the transporting device to the destination. Under the supporting and dispersing action of the shoulder strap 200, even in difficult environments such as mountains, goods can be effectively transported, ensuring the high efficiency and safety of the transportation of photovoltaic modules during the construction of mountain photovoltaic power stations.

[0052] Therefore, the transporting device provided by the embodiment of the present application effectively reduces the handling labor intensity of the photovoltaic module and improves the handling efficiency and safety of large items such as photovoltaic modules under complex terrain conditions, thus contributing to the construction of mountain photovoltaic power stations.

[0053] In an alternative embodiment, please refer to Figure 4, the first clamping member 310 includes a first sliding portion 311 and a first clamping portion 312. The first sliding portion 311 is slidably connected to the first installation groove 510, and a part of the first clamping portion 312 is located outside the plate body 100; the second clamping member 320 includes a second sliding portion 321 and a second clamping portion 322. The second sliding portion 321 is slidably connected to the second installation groove 520, and a part of the second clamping portion 322 is located outside the plate body 100.

[0054] The first sliding portion 311 is slidably connected to the first installation groove 510 on one side of the plate body 100, so that the first clamping member 310 can telescopically move along the first installation groove 510 to adapt to the clamping requirements of photovoltaic modules of different sizes. The first clamping portion 312 extends partially outside the plate body 100 and is used to directly contact and fix the goods. The surface thereof may be provided with anti-slip textures or covered with soft materials to ensure that the goods can be firmly grasped during clamping and the surface of the goods can be prevented from being damaged. Similarly, the second clamping member 320 is composed of a second sliding portion 321 and a second clamping portion 322. The second sliding portion 321 matches the second installation groove 520 on the other side of the plate body 100, and the second clamping portion 322 effectively fixes the goods from the other side to ensure the stability and safety of the loaded goods through bilateral clamping.

[0055] During actual operation, the transporter first adjusts the positions of the first sliding portion 311 and the second sliding portion 321 manually or electrically according to the size of the photovoltaic module, so that the two clamping portions can closely fit the side edges of the photovoltaic module. In this way, the transportation device can adapt to photovoltaic modules or other materials of different widths. Through the design of the external clamping portions, the operator has an unobstructed view during adjustment, which is more intuitive and convenient. Once the adjustment is in place, force is applied through the adjustment mechanism to make the two clamping portions tighten inward until the goods are stably wrapped and fixed. This process simplifies the preparatory work before handling, improves work efficiency, and ensures the stability and protection of the goods during the entire handling process.

[0056] Exemplarily, the clamping portion is U-shaped or V-shaped, and the first clamping portion 312 and the second clamping portion 322 are oppositely arranged on both sides of the plate body 100. In this way, the two clamping portions form a clamping space to limit the photovoltaic module placed on the plate body 100. The plate body 100 is of a frame structure, which is beneficial to reducing the weight of the entire device and lightening the carrying burden.

[0057] In an alternative embodiment, please refer to Figure 1 and Figure 6 , the transportation device further includes a trough body 500. The trough body 500 is connected to the plate body 100, and a first installation groove 510 is provided on one side of the trough body 500, and a second installation groove 520 is provided on the other side.

[0058] The first clamping member 310 is provided in the first installation groove 510, and the second clamping member 320 is provided in the second installation groove 520. The groove body 500 is conducive to simplifying the structure of the plate body 100 and ensuring the structural strength of the plate body 100. At the same time, during maintenance and inspection, the groove body 500 is also convenient for quickly positioning and dealing with possible wear or fault problems. The connection mode between the groove body 500 and the plate body 100 can be welding, screw fixation or other reliable mechanical connection modes to ensure the firmness and reliability of the entire device when transporting heavy objects in complex terrains.

[0059] In an alternative embodiment, the adjusting mechanism includes a gear member 610 and a driving member 620.

[0060] The gear member 610 is arranged between the first sliding portion 311 and the second sliding portion 321. The first sliding portion 311 and the second sliding portion 321 are arranged oppositely, and both the first sliding portion 311 and the second sliding portion 321 are in gear engagement with the gear member 610;

[0061] The driving member 620 is connected to the gear member 610. The driving member 620 drives the gear member 610 to rotate so that the first sliding portion 311 and the second sliding portion 321 approach and separate from each other.

[0062] The gear member 610 is installed between the first sliding portion 311 and the second sliding portion 321, and both the first sliding portion 311 and the second sliding portion 321 are designed with a rack structure matching it to ensure that the two can be in gear-rack engagement. In this way, when the gear member 610 rotates, it can simultaneously drive the first sliding portion 311 and the second sliding portion 321 to make coordinated relative movements along their respective installation grooves, not only realizing synchronous adjustment but also ensuring the smoothness and precise control during the adjustment process.

[0063] The driving member 620, as the power source of the entire adjustment mechanism, is directly connected to the gear member 610. The driving member 620 can be a manual knob, an electric motor or other power transmission devices, which are selected according to the needs of the actual application scenario. When the operator starts the driving member 620, the driving force is transmitted to the gear member 610, triggering the rotational movement of the gear. This rotational action is immediately converted into the linear movement of the sliding portion along the installation groove, thereby controlling the relative position of the first clamping member 310 and the second clamping member 320 and realizing the precise adjustment of the clamping force on the goods.

[0064] During use, the operator first starts the entire adjustment process according to the size of the goods by manipulating the driving member 620 (such as turning a manual knob or pressing an electric button). The driving member 620 drives the gear member 610 to rotate. The teeth on the gear member 610 are precisely engaged with the gears in the first sliding portion 311 and the second sliding portion 321, driving the two sliding portions to slide inwards or outwards synchronously. In this way, the first clamping portion 312 and the second clamping portion 322 approach or move away from each other to achieve the best clamping state suitable for the current size of the goods. The above adjustment process is smooth, labor-saving, and has high adjustment accuracy, ensuring that the fixation preparation of the goods can be completed quickly and efficiently under various working conditions, which is beneficial to improving the flexibility and operation convenience of the transportation device.

[0065] In an alternative embodiment, the driving member 620 includes a connecting rod and a knob. The connecting rod has opposite first and second ends. The first end is connected to the gear member 610, and the second end is located outside the plate body 100 and is connected to the knob.

[0066] The first end of the connecting rod is directly connected to the gear member 610, ensuring the effective transmission of the operating force. The knob is installed at the second end of the connecting rod and is located outside the plate body 100, facilitating direct manual operation by the operator.

[0067] Optionally, the connecting rod is made of a high-strength material, which not only ensures sufficient mechanical strength to withstand the torque during the adjustment process but also maintains the necessary flexibility to adapt to the operating requirements at different angles. The surface of the knob is treated with anti-slip to ensure the adjustment accuracy and operating comfort.

[0068] It can be understood that a self-locking structure is provided between the knob and the connecting rod so that the first clamping member 310 and the second clamping member will not change due to slight external force during transportation. Exemplarily, a set of self-locking gears or ratchet structures are embedded inside the knob and are engaged with the end of the connecting rod. When the knob is rotated to the desired position, a specific tooth shape in the gear or ratchet will engage with the corresponding card slot or pawl to form a self-locking state.

[0069] During operation, the user only needs to simply rotate the knob located outside the plate body 100, transfer the rotational torque to the internal gear member 610 through the connecting rod, and drive the first sliding portion 311 and the second sliding portion 321 to move synchronously along their respective installation grooves, thereby adjusting the opening and closing of the clamping member. This enables the operator to complete the adjustment with an intuitive feel even under conditions of limited space or inconvenient visual observation, greatly improving the flexibility and efficiency of the operation.

[0070] In an alternative embodiment, the first clamping member 310 further includes a first elastic connection portion 313, and the first sliding portion 311 and the first clamping portion 312 are connected by the first elastic connection portion 313; the second clamping member 320 further includes a second elastic connection portion 323, and the second sliding portion 321 and the second clamping portion 322 are connected by the second elastic connection portion 323.

[0071] Since the first elastic connection portion 313 is located between the first sliding portion 311 and the first clamping portion 312, when encountering bumps or vibrations during transportation, the first elastic connection portion 313 can absorb and disperse these external forces, reduce the amplitude of vibrations directly transmitted to the photovoltaic module, and reduce the degree of rigid collision between the first clamping portion 312 and the photovoltaic module, thereby protecting the photovoltaic module from damage. Similarly, the second elastic connection portion 323 plays the same role.

[0072] Optionally, the first elastic connection portion 313 and the second elastic connection portion 323 are made of rubber or spring materials.

[0073] When the transportation device carries the photovoltaic module and travels on an uneven road surface, the rubber or spring materials of the first elastic connection portion 313 and the second elastic connection portion 323 can elastically deform, absorb and consume most of the vibration energy, and prevent this energy from being directly transmitted to the fragile photovoltaic module. In this way, not only the potential damage caused by vibrations, such as cracks or performance degradation, is reduced, but also the overall transportation smoothness is improved, and the safety factor of the operation is increased.

[0074] In this embodiment, through the first elastic connection portion 313 and the second elastic connection portion 323, the protection ability of the transportation device for the goods is enhanced, especially suitable for handling valuable items such as vibration-sensitive photovoltaic modules, ensuring efficient and safe logistics transportation under harsh terrain conditions.

[0075] In an alternative embodiment, in order to further improve the stability and safety of the goods during handling, anti-slip pads 301 are provided on the surfaces of both the first clamping portion 312 and the second clamping portion 322.

[0076] On the contact surfaces of the first clamping portion 312 and the second clamping portion 322, that is, the parts directly in contact with the goods, a layer of high-performance anti-slip pads is covered. It can be understood that the anti-slip pads 301 are made of materials with a high coefficient of friction, such as rubber, silicone, or synthetic materials with special textures, to increase the friction with the surface of the goods and effectively prevent the goods from slipping even on inclined or bumpy road surfaces. In addition, in order to protect the sensitive surface of the photovoltaic module, the anti-slip pads 301 also need to have softness to ensure that no scratches or damages are caused to the module during tight clamping.

[0077] In this embodiment, by adding an anti-slip pad 301 on the surface of the clamping part, the transportation device can significantly improve the grasping force for goods such as photovoltaic modules during actual application. Even when not fully closed, it can maintain good stability, reducing potential safety hazards during transportation. At the same time, this also helps to reduce energy loss caused by sliding, protect the integrity of the photovoltaic module, and ensure its optimal performance after installation.

[0078] Different from the first clamping member 310 mentioned previously being slidably connected to the first installation groove 510, please refer to Figure 5 , in an alternative embodiment, the first clamping member 310 is threadedly connected to the first installation groove 510, and the second clamping member 320 is threadedly connected to the second installation groove 520.

[0079] In this embodiment, the first clamping member 310 is connected to the first installation groove 510 through a threaded structure. Similarly, the second clamping member 320 is also connected to the second installation groove 520 through a threaded structure. This means that the operator can adjust the positions of the first clamping member 310 and the second clamping member 320 in their respective installation grooves by rotating them, achieving precise clamping of the goods.

[0080] Through the design of the threaded interface, when it is necessary to adjust the clamping width, the operator can manually rotate the first clamping member 310 or the second clamping member 320, just like turning a screw, to make it move along the threaded track of the installation groove. This method provides continuous and fine adjustment capabilities, allowing for fine-tuning according to the specific dimensions of the goods to ensure the tightness and adaptability of the clamping.

[0081] Compared with the sliding connection, the threaded connection can provide stronger fixing force and stability in the locked state. Even when encountering relatively severe vibrations or tilts during transportation, it can effectively prevent the accidental sliding of the clamping members, protecting the safety of the goods. In addition, the self-locking characteristic of the threaded connection also contributes to the structural stability during long-term use, reducing wear caused by repeated adjustment.

[0082] In an alternative embodiment, in order to further enhance the shock absorption performance of the transportation device, the receiving seat 400 is provided with a limiting groove along the transverse direction of the plate body 100, and a shock pad 401 is arranged in the limiting groove.

[0083] The limiting groove is arranged along the transverse direction of the plate body 100, and a high-performance shock pad 401 is embedded in the limiting groove. When subjected to external impact or vibration, it can effectively absorb and disperse energy, reducing the direct transmission of this energy to the plate body 100 and the goods, thereby protecting the photovoltaic module from damage. Optionally, the shock pad 401 is usually made of highly elastic and wear-resistant materials such as rubber, polyurethane, or special shock-absorbing composite materials.

[0084] In an alternative embodiment, in order to improve the comfort of the operator when carrying the transport device and reduce the discomfort of pressure points, a soft pad 101 is provided on one side of the plate body 100 close to the strap 200.

[0085] Through its buffering effect, the soft pad 101 can effectively disperse the pressure of the strap 200 on the operator's back, reducing the fatigue and local compression caused by long-term carrying. At the same time, the soft pad 101 can be made breathable to help discharge heat and moisture, keeping the carrying area dry, especially in hot or high-intensity physical labor environments.

[0086] The soft pad 101 can be made of high-density sponge, memory foam or synthetic materials with shock-absorbing properties, having good shock absorption and breathability.

[0087] In this embodiment, by adding a soft pad 101 to the contact surface between the plate body 100 and the strap 200, the comfortable experience of the operator during handling is significantly improved, the adverse effects of carrying heavy objects on the body are reduced, and the ability to work continuously is extended. For the construction personnel of mountain photovoltaic power stations who need to carry out long-term and long-distance handling in complex terrains, it helps to improve work efficiency and reduce occupational injuries.

[0088] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the utility model disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application.
