However, the solar cells themselves are very fragile and are easily damaged after being collided or squeezed, which will affect the power generation efficiency. During transportation, photovoltaic panels are usually stacked together, and the stacked photovoltaic panels are prone to sliding during transportation. After the photovoltaic panels slide, they are likely to collide with other photovoltaic panels or other items in the transport vehicle, causing physical damage, which may lead to cracks, breakage, or complete damage of the photovoltaic panels, thus affecting their power generation efficiency.

Detailed Embodiment

[0027] The following further describes the embodiments of the invention in detail with reference to the drawings of the specification, so as to more clearly present the purpose, technical solution and technical effect of the present invention.

[0028] Reference Figures 1 to 5 , a photovoltaic panel transportation protection device, includes a storage rack 1, a plurality of outer shells 2 are horizontally fixed on the storage rack 1, the plurality of outer shells 2 are evenly spaced in the vertical direction, a storage cavity 3 for loading the photovoltaic panel is opened inside the outer shell 2, and a storage opening 4 communicating with the storage cavity 3 is arranged on one side of the outer shell 2; an airbag 5 is arranged at the top of each storage cavity 3, the airbag 5 covers the entire top of the storage cavity 3, and an air supply assembly 19 for supplying air to the airbag 5 is arranged outside the storage rack 1. Among them, the air supply assembly 19 can be an air pump or other devices or mechanisms capable of inflating the airbag 5.

[0029] When using, refer to Figures 1 to 5 , one side of the glass cover of the airbag 5 faces upward, and the back plate is inserted horizontally into the storage cavity 3 from the storage port 4. Only one photovoltaic panel is stored in each storage cavity 3. Then the air supply assembly 19 inflates the airbag 5, and the airbag 5 begins to expand. After the airbag 5 expands, it begins to squeeze the surface of the glass cover from above the photovoltaic panel, and squeezes the photovoltaic panel toward the bottom of the storage cavity 3, increasing the friction between the back plate of the photovoltaic panel and the bottom of the storage cavity 3. The friction between the back plate of the photovoltaic panel and the bottom of the storage cavity 3 is used to fix the photovoltaic panel to the storage cavity 3, preventing the photovoltaic panel from sliding during transportation and colliding with the side wall of the storage cavity 3, thereby avoiding damage to the photovoltaic panel. The photovoltaic panel is fixed together with the outer shell 2 in the storage cavity 3, and the outer shell 2 is fixed together with the storage rack 1, so the photovoltaic panel and the storage rack 1 are fixed as a whole, and multiple photovoltaic panels are installed in multiple outer shells 2 of the storage rack 1. Therefore, the weight of the storage rack 1 is increased, and the storage rack 1 is not easy to move during transportation, and it is not easy to collide due to sliding, and then the photovoltaic panel inside the storage rack 1 is not easy to be impacted, and the photovoltaic panel is not easy to be damaged.

[0030] In addition, the airbag 5 is used to squeeze the photovoltaic panel. Since the airbag 5 itself has a certain ductility, if vibration occurs during transportation, the airbag 5 can be deformed to reduce the impact between the photovoltaic panel and the airbag 5, which helps to protect the glass cover on the surface of the photovoltaic panel from being damaged by vibration during transportation.

[0031] refer to Figure 1 and Figure 3 , a closing component is also provided at each receiving port 4. The closing component includes a rotating plate 12 rotatably mounted on the housing 2, the rotating plate 12 is located on one side of the housing 2 where the receiving port 4 is located, a lock 13 for buckling the rotating plate 12 is also provided below the rotating plate 12, and a push spring 14 for keeping the photovoltaic panel pushed into the receiving chamber 3 is fixedly installed on the rotating plate 12. The rotating plate 12 of the closing component is buckled on the lock 13 to block the receiving port 4 to prevent the photovoltaic panel from slipping out of the receiving slot and being damaged. The push spring 14 pushes the photovoltaic panel toward the side of the receiving slot opposite to the receiving port 4, allowing the photovoltaic panel to resist, and further allows the photovoltaic panel to be connected and fixed to the receiving chamber 3, further preventing the photovoltaic panel from colliding and being damaged by the side wall of the receiving slot during transportation.

[0032] refer to Figure 4 A sponge pad 6 is fixedly mounted on one side of the airbag 5 facing the bottom of the storage cavity 3. The sponge pad 6 is softer than the airbag 5, which helps to avoid scratching the surface of the photovoltaic panel.

[0033] refer to Figure 2 and Figure 4, a limiting plate 7 is slidably arranged on each of the left and right sides of the storage cavity 3. On the mutually facing sides of the two limiting plates 7, a compression spring 8 is fixedly installed. One end of each compression spring 8 is connected to the limiting plate 7, and the other end is fixedly connected to the side wall of the storage groove opposite to the limiting plate 7. Since the sizes of the photovoltaic panels are different, to prevent the photovoltaic panels from colliding with the side walls of the storage groove during transportation, it is necessary to connect the photovoltaic panels to the side walls of the storage groove. By pushing the limiting plate 7 with the compression spring 8, the compression spring 8 can be used to adapt to photovoltaic panels of different sizes, and the gap between the photovoltaic panel and the storage cavity 3 is filled by the compression spring 8, further connecting the photovoltaic panel and the storage cavity 3 into a whole. The limiting plate 7 is always in contact with the side wall of the photovoltaic panel, avoiding the collision between the photovoltaic panel and the side wall of the storage cavity 3. When the photovoltaic panel slides due to large inertia during transportation, the compression spring 8 can also absorb the kinetic energy by deforming, further preventing the photovoltaic panel from being damaged.

[0034] Furthermore, the height of the limiting plate 7 is less than the height of the photovoltaic panel, ensuring that the airbag 5 and the sponge pad 6 can evenly press on the surface of the photovoltaic panel.

[0035] Reference Figure 4 , the distance between the two limiting plates 7 gradually decreases from the direction of the storage opening 4 towards the inside of the storage cavity 3, and the two limiting plates 7 are arranged in a "V" shape. The opening of the "V" shape has a guiding effect, enabling the photovoltaic panel to be more conveniently inserted into the storage cavity 3.

[0036] Reference Figure 1 、 Figure 4 and Figure 5 , a ventilation pipe 9 is arranged on the storage rack 1. The airbags 5 are all communicated with the ventilation pipe 9. A pressure relief valve 10 is arranged on the ventilation pipe 9. The ventilation pipe 9 is communicated with the air supply assembly 19. A pressure sensor 11 is arranged between one of the airbags 5 and the sponge pad 6. The air supply assembly 19 simultaneously inflates all the airbags 5 through the ventilation pipe 9, which can ensure that the pressure inside each airbag 5 is equal, facilitating the control of the pressure of the airbags 5. The pressure sensor 11 helps the staff intuitively understand the pressure between the airbag 5 and the photovoltaic panel, avoiding damage to the photovoltaic panel caused by excessive extrusion pressure of the airbag 5 on the photovoltaic panel. The pressure relief valve 10 can regulate the pressure of the airbag 5 and automatically discharge the gas inside the airbag 5 when the pressure inside the airbag 5 exceeds the set pressure, ensuring that the photovoltaic panel will not be damaged.

[0037] Reference Figure 1 and Figure 3A shock absorbing platform 15 is arranged below the storage rack 1. The shock absorbing platform 15 is square and has vertical plates around it. The vertical plates of the shock absorbing platform 15 respectively abut against the four sides of the storage rack 1 to prevent the storage rack 1 from shaking left and right. A shock absorbing spring 16 is arranged between the storage rack 1 and the shock absorbing platform 15. There are four shock absorbing springs 16. The four shock absorbing springs 16 are respectively arranged at the four corners of the shock absorbing platform 15. One end of the shock absorbing spring 16 is fixedly mounted on the storage rack 1, and the other end is fixedly mounted on the shock absorbing platform 15. The photovoltaic panel is fixed in the storage cavity 3. The photovoltaic panel and the outer shell 2 are an integral whole. The outer shell 2 is fixed to the storage rack 1 and is an integral whole with the storage rack 1. Therefore, the photovoltaic panel will not collide with the outer shell 2 and the storage rack 1 and be damaged. However, in the process of transporting photovoltaic panels, the road surface in the form of vehicles is uneven, which may cause the storage rack 1 to vibrate or jump. The shock-absorbing spring 16 can effectively reduce the impact force of the storage rack 1 when it vibrates or jumps, and further prevent the impact force of the storage rack 1 due to vibration, jumping and falling from being transmitted to the photovoltaic panel and causing damage to the photovoltaic panel.

[0038] refer to Figure 1 , Figure 3 and Figure 4 The four side walls of the shock absorbing platform 15 are all provided with springs 18, one end of the springs 18 is fixed on the side wall of the shock absorbing platform 15, and the other end is bent upward. With the provision of the springs 18, when the truck is transporting photovoltaic panels, the shock absorbing platform 15 may slide inside the truck compartment, and the sliding shock absorbing platform 15 may collide with the side panels of the compartment. The springs 18 are provided around the shock absorbing platform 15, and can absorb the impact force by deforming when the shock absorbing platform 15 collides with the side wall of the compartment or other objects. This reduces the impact force transmitted to the storage rack 1, and avoids damage to the photovoltaic panels on the storage rack 1.

[0039] refer to Figure 1, a notch 17 is also provided on the lower side of the outer shell 2. Since the back panel of the photovoltaic panel will contact the bottom surface of the storage cavity 3 after the photovoltaic panel is inserted into the storage groove, and in order to ensure that the photovoltaic panel will not slide and collide with the side wall of the storage cavity 3 during transportation, the pushing spring 14 is used to push the photovoltaic panel into the storage cavity 3. Therefore, the bottom surface of the photovoltaic panel is completely blocked by the bottom surface of the storage cavity 3, which is not conducive to taking out the photovoltaic panel from the storage cavity 3. After the notch 17 is opened, the back panel of the photovoltaic panel will be exposed at the notch 17. When it is necessary to take out the photovoltaic panel from the storage cavity 3, the back panel of the photovoltaic panel can be grasped from the notch 17 by hand to pull the photovoltaic panel out of the storage cavity 3, which is convenient for taking out the photovoltaic panel from the storage cavity 3. In addition, in order to further improve the stability when grasping the photovoltaic panel, there can be two notches 17, and the two notches 17 are symmetrically arranged with respect to the rotating plate 12, which is convenient for the staff to grasp the photovoltaic panel with both hands. The above is only a preferred and feasible embodiment of the present invention, and is not used to limit the scope of the patent application of the present invention. Any equivalent changes, equivalent substitutions or modified changes completed within the technical spirit and principles disclosed by the present invention shall be included within the scope of patent protection covered by the present invention.
