The adjustment component is arranged on the support plate, and each fixing plate is arranged on the adjustment component. Although the above patent can protect the solar photovoltaic panels during transportation, one limiting component limits the height of one photovoltaic panel.

A limiting plate 11 is slidably connected to the upper part inside the frame body 10. The limiting plate 11 slidably penetrates through the positioning plate 8. A triggering component is arranged between the frame body 10 and the positioning plate 8. The triggering component is used to drive the limiting plate 11 to move. The limiting plate 11 moves into contact with the solar photovoltaic panel so that the limiting plate 11 limits the solar photovoltaic panel.

[0032] Please refer to Figures 5 - 8As shown in the figure, the triggering component includes a contact rod 121, a rotating component, a bevel gear disk 126, a disk 127, a magnetic ring I 128, and a magnetic ring II 1281. The bevel gear disk 126 is rotatably connected to the bottom of the left and right side frames 10. One-word holes 12 are formed in the left and right limit plates 11. A magnetic ring I 128 is fixedly connected to the middle of the top of the bevel gear disk 126. A disk 127 is magnetically attracted inside the magnetic ring I 128. A contact rod 121 is fixedly connected to an eccentric position on the top of the disk 127. The contact rod 121 is located inside the one-word hole 12. When the contact rod 121 rotates, the contact rod 121 can drive the one-word hole 12 to move left and right. A magnetic ring II 1281 is fixedly connected to the middle of the outer bottom of the frame 10. The inner side of the magnetic ring II 1281 is in magnetic contact with the shaft portion of the disk 127. A rotating component is arranged between the frame 10 and the positioning plate 8. When the rotating component operates, the rotating component can drive the bevel gear disk 126 to rotate. The rotating component includes a gear shaft 122, a rodless cylinder 123, a rack 124, and a bevel gear 125. The gear shafts 122 are rotatably connected to the outer bottom of the frame 10. Bevel gears 125 are fixedly sleeved on the gear shafts 122. The bevel gears 125 are meshed with the bevel gear disk 126. Rodless cylinders 123 are installed on the mutually remote sides of the left and right positioning plates 8. The rodless cylinders 123 are electrically connected to the ultrasonic sensors 6. A rack 124 is fixedly connected to the moving part of the rodless cylinder 123. The rack 124 is meshed with the gear shaft 122.

[0033] Please refer to Figure 9 As shown in the figure, the buffering component includes shock absorbers 13, fixed seats 131, electric push rods 132, and movable rods 133. Four shock absorbers 13 are evenly spaced and installed between the inner top and inner bottom of the box body 1. The tail ends of the shock absorbers 13 are rotatably connected to the outer side surface of the loading box 3. The shock absorbers 13 can buffer and damp the loading box 3. Fixed seats 131 are fixedly connected to the outer top and outer bottom of the loading box 3 in a left-right symmetric manner. Electric push rods 132 are installed on the top and bottom of the box body 1. Movable rods 133 are fixedly connected to the end portions of the telescopic rods of the upper and lower electric push rods 132. The movable rods 133 correspond to the fixed seats 131. When the movable rods 133 move and contact the fixed seats 131, the movable rods 133 can fix the fixed seats 131 to complete the fixation of the loading box 3.

[0034] First, place this device on the transport vehicle, then pull the box door 21 to open it. Twist the screw rod 9 to rotate, driving the four positioning plates 8 to move synchronously in and out. When the four positioning plates 8 move synchronously in and out to a position suitable for positioning the solar photovoltaic panel, stop twisting the screw rod 9. Pull the box door 21 to close it, then start the electric cover plate 4 to swing downward to open. The electric cover plate 4 swinging downward drives the electric support roller 41 to swing downward. The electric support roller 41 swings downward to the same height as the electric conveying roller 5. Start the electric push rod 132. The telescopic rod of the electric push rod 132 extends to drive the upper and lower movable rods 133 to move inward. The movable rods 133 move inward to contact the fixed seat 131, and the movable rods 133 fix the fixed seat 131, thus completing the fixation of the loading box 3. Close the electric push rod 132, then the ultrasonic sensor 6 can be started. At the same time, start the electric guide roller 2, the electric support roller 41, and the electric conveying roller 5 to rotate forward. Then the solar photovoltaic panel can be placed on the electric guide roller 2 from the front side. The electric guide roller 2 rotating forward drives the solar photovoltaic panel to move backward to contact the electric support roller 41. The electric support roller 41 supports and guides the solar photovoltaic panel, enabling the solar photovoltaic panel to continue moving backward to contact the electric conveying roller 5. When the solar photovoltaic panel moves backward to the maximum stroke inside the loading box 3, start the electric lifting plate 7 to move upward to contact the solar photovoltaic panel. The electric lifting plate 7 drives the solar photovoltaic panel to move upward. The solar photovoltaic panel moves to contact the four positioning plates 8. The positioning plates 8 position and guide the solar photovoltaic panel. The ultrasonic sensor 6 detects the distance from the solar photovoltaic panel. When the solar photovoltaic panel moves upward to the maximum stroke and the ultrasonic sensor 6 detects that the distance from the solar photovoltaic panel reaches the set value, the ultrasonic sensor 6 first controls the rodless cylinder 123 through the control module. The moving part of the rodless cylinder 123 moves downward to drive the rack 124 to move downward. The rack 124 moving downward drives the gear shaft 122 to rotate. The gear shaft 122 rotating drives the bevel gear 125 to rotate. The bevel gear 125 rotating drives the bevel gear disk 126 to rotate. The bevel gear disk 126 rotates idly within the magnetic ring II 1281. The bevel gear disk 126 rotating drives the magnetic ring I 128 to rotate. The magnetic ring I 128 rotating drives the disk 127 to rotate through magnetic force. The disk 127 rotating drives the contact rod 121 to rotate. The contact rod 121 rotating drives the left and right limiting plates 11 to move inward through the slotted hole 12. When the limiting plates 11 move inward to contact the side of the solar photovoltaic panel, the limiting plates 11 stop moving inward. The limiting plates 11 clamp the solar photovoltaic panel. The limiting plates 11 make the contact rod 121 stop rotating through the slotted hole 12. The contact rod 121 makes the disk 127 stop rotating. The bevel gear disk 126 continues to rotate to drive the magnetic ring I 128 to rotate idly. When the rack 124 continues to move downward to disengage from the gear shaft 122, the gear shaft 122 stops rotating. The bevel gear disk 126 stops driving the magnetic ring I 128 to rotate. The magnetic ring II 1281 sucks and fixes the bevel gear disk 126.As the rack 124 continues to move downward and meshes with the next gear shaft 122, the rack 124 drives the next gear shaft 122 to rotate, causing the next limit plate 11 to move inward. When the limit plate 11 moves inward and contacts the bottom of the solar photovoltaic panel, the limit plate 11 supports and limits the solar photovoltaic panel, and then the rodless cylinder 123 is closed. Then the ultrasonic sensor 6 controls the electric lifting plate 7 to move downward and reset through the control module, and then the solar photovoltaic panel is placed on the electric guide roller 2 from the front again. The electric guide roller 2 rotates forward and continues to drive the solar photovoltaic panel to move backward. According to the above operation, the solar photovoltaic panel can be moved upward for placement, and this process can be repeated continuously. The solar photovoltaic panels are stacked in the loading box 3, so that the space in the loading box 3 is fully utilized. When the loading box 3 is full of solar photovoltaic panels, the ultrasonic sensor 6, the electric guide roller 2, the electric support roller 41 and the electric conveying roller 5 are turned off, and the electric cover 4 is started to swing upward and closed, and the electric cover 4 seals the loading box 3, and the electric push rod 132 is started to drive the upper and lower side movable rods 133 to move outward and disengage from the fixed seat 131, so that the fixing of the loading box 3 is stopped, and the solar photovoltaic panels after clamping and limiting can be transported. During the transportation process, under the action of the shock absorber 13, the loading box 3 can be buffered and damped, which also reduces the solar photovoltaic panels in the loading box 3. The back plate is used for buffering and shock absorption, thereby ensuring the safety of the solar photovoltaic panels in the loading box 3. In this way, the space can be fully utilized to clamp and limit a large number of solar photovoltaic panels to complete the transportation, thereby improving the transportation efficiency of the solar photovoltaic panels. When the solar photovoltaic panels are transported to the specified position, the electric cover 4 is started to swing downward and open according to the above operation, and the electric push rod 132 is started to drive the movable rod 133 to contact with the fixing seat 131 to complete the fixation of the loading box 3, and then the electric lifting plate 7 is started to move upward and contact with the lowest solar photovoltaic panel, and the rodless cylinder 123 is started to drive the rack 124 to move upward, and the rack 124 drives the gear shaft 122 to rotate in the opposite direction, so that it is in contact with the lowest solar photovoltaic panel. The contacting limit plate 11 moves outward and disengages from the lowest solar photovoltaic panel, and the electric lifting plate 7 supports the lowest solar photovoltaic panel. The electric lifting plate 7 is started to move downward to drive the solar photovoltaic panel to move downward and contact the electric conveying roller 5. The electric conveying roller 5, the electric support roller 41 and the electric guide roller 2 are started to reverse. The electric conveying roller 5 reverses to drive the solar photovoltaic panel to move forward and contact the electric support roller 41 and the electric guide roller 2. The electric support roller 41 and the electric guide roller 2 reverse to drive the solar photovoltaic panel to move forward to the outside of the box 1, and the solar photovoltaic panel can be stored. This is repeated to continuously transport the solar photovoltaic panels in the loading box 3 to the outside of the box 1.

[0035] See also Figure 10 and Figure 11As shown, the solar photovoltaic panel transfer protection device further includes a protection component installed between the box body 1 and the loading box 3. The protection component includes a ventilation fan 14, a temperature and humidity sensor 141, a gas supply component, a spray pipe 144, and a heating wire 145. Ventilation fans 14 are symmetrically installed front and back between the lower right part of the loading box 3 and the lower right part of the box body 1. The ventilation fan 14 can ventilate the inside of the loading box 3. Spray pipes 144 are symmetrically and fixedly connected to the front and back of the left side surface inside the loading box 3. The air outlet end of the spray pipe 144 faces to the right. A heating wire 145 is arranged inside the spray pipe 144. Temperature and humidity sensors 141 are symmetrically installed front and back on the right side of the top of the loading box 3. The temperature and humidity sensor 141 is electrically connected to the heating wire 145 and the ventilation fan 14. A gas supply component is arranged between the box body 1 and the loading box 3. When the gas supply component operates, the gas supply component can discharge air into the spray pipe 144. The gas supply component includes an air pump 142 and a three-way pipe 143. The air pump 142 is installed on the left side of the outer top of the box body 1. The air pump 142 is electrically connected to the temperature and humidity sensor 141. The air outlet end of the air pump 142 is connected to the three-way pipe 143. The three-way pipe 143 penetrates through the box body 1 and the loading box 3. The two air outlet ends of the three-way pipe 143 are respectively connected to the tops of the front and rear spray pipes 144. The three-way pipe 143 can discharge air into the spray pipe 144.

[0036] When the solar photovoltaic panel is being transported, the temperature and humidity sensor 141 monitors the temperature and humidity inside the loading box 3. When the temperature inside the loading box 3 is relatively high, the temperature and humidity sensor 141 controls the air pump 142 to start through the control module. The air pump 142 starts to discharge air into the tee pipe 143, and the air in the tee pipe 143 is discharged into the air injection pipe 144. The air injection pipe 144 discharges air into the loading box 3. At the same time, the temperature and humidity sensor 141 controls the ventilation fan 14 to rotate through the control module. The ventilation fan 14 rotates to extract air from the loading box 3. In this way, the air injection of the air injection pipe 144 and the air extraction of the ventilation fan 14 can complete the ventilation and heat dissipation of the loading box 3, so that the solar photovoltaic panel can be transported in a suitable temperature environment. When the temperature inside the loading box 3 drops to a suitable temperature, the temperature and humidity sensor 141 controls the air pump 142 and the ventilation fan 14 to close through the control module. The air pump 142 stops discharging air into the tee pipe 143, the air injection pipe 144 stops ejecting air, and at the same time the ventilation fan 14 stops extracting air from the loading box 3. When the temperature inside the loading box 3 is relatively humid, the temperature and humidity sensor 141 controls the heating wire 145 to start through the control module, and at the same time also controls the air ventilation fan 14 and the air pump 142 to start through the control module. When air is discharged into the air injection pipe 144, the air in the air injection pipe 144 is heated by the heating wire 145, and the hot air is sprayed into the loading box 3 through the air injection pipe 144. The hot air dries the inside of the loading box 3, making the inside of the loading box 3 in a dry state. The ventilation fan 14 extracts the hot air from the loading box 3. When the inside of the loading box 3 reaches a dry degree, the temperature and humidity sensor 141 controls the air pump 142, the heating wire 145 and the ventilation fan 14 to close through the control module. In this way, it is possible to prevent the high temperature and humidity inside the loading box 3 from affecting the solar photovoltaic panel, thus ensuring the safety of the solar photovoltaic panel during the transportation process.

[0037] Please refer to Figure 12 As shown, the solar photovoltaic panel transportation protection device further includes balls 15. The front side of the top of the electric lifting plate 7 is rotatably connected with balls 15 at equal intervals. When the solar photovoltaic panel contacts the balls 15, the balls 15 can guide the solar photovoltaic panel.

[0038] When the electric lifting plate 7 moves upward, the electric lifting plate 7 drives the balls 15 to move upward. The balls 15 move upward and contact the solar photovoltaic panel. The electric lifting plate 7 drives the solar photovoltaic panel to move upward through the balls 15. The balls 15 reduce the friction between the electric lifting plate 7 and the solar photovoltaic panel. In this way, it is possible to prevent the solar photovoltaic panel from being in hard contact with the electric lifting plate 7 and generating friction and wear, thus ensuring the complete quality of the solar photovoltaic panel.
