Description

Technical Field

This foam must be fitted around the edges and frames of the panels, requiring customization. Furthermore, thinner foam can cause deformation due to impact if thrown or displaced during transport. Thicker foam reduces the number of panels that can be transported, reducing transportation efficiency. Furthermore, the transport foam and cardboard cannot be recycled promptly, hindering the environmentally friendly use of resources. Furthermore, assembly and disassembly is time-consuming, increasing transportation costs. Summary of the Invention

[0044] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0045] like Figures 1-15 The present invention provides a photovoltaic panel transportation protection device whose main function is to improve the efficiency of photovoltaic loading and unloading, reduce the labor intensity of workers, and improve the protection effect during transportation.

[0046] like Figure 1-3 As shown, the photovoltaic panel transportation protection device includes a movable end plate 1 and a fixed end plate 2 arranged vertically and symmetrically, and a plurality of photovoltaic panel storage assemblies 3 arranged in a horizontal array between the movable end plate 1 and the fixed end plate 2. The movable end plate 1, the fixed end plate 2, and the plurality of photovoltaic panel storage assemblies 3 of this device can be combined to form a box. During transportation, the plurality of photovoltaic panel storage assemblies 3 each store a photovoltaic panel, isolating and protecting each photovoltaic panel separately to prevent collision and friction between adjacent photovoltaic panels, which may cause damage to the photovoltaic panels.

[0047] Combine Figure 6 and Figure 7As shown, the photovoltaic panel storage assembly 3 includes a U-shaped base strip 31 formed by an upper base strip 311, a lower base strip 312 and a side base strip 313. A U-shaped storage groove 32 for storing photovoltaic panels is provided on the inner side of the U-shaped base strip 31, and an opening 33 for the photovoltaic panel to slide in and out is formed on the side of the U-shaped storage groove 32 away from the side base strip 313. When loading and unloading photovoltaic panels, the staff can slide the photovoltaic panel into and out of the U-shaped storage groove 32 in a sideways sliding manner from the opening 33 of the U-shaped storage groove 32. The bottom end of the U-shaped storage groove 32 is evenly provided with rotating rollers 34 along its length. The thickness and width of the photovoltaic panel are both smaller than the size of the U-shaped storage groove 32, that is, the U-shaped The size of the storage groove 32 is larger than the size of the photovoltaic panel. When the photovoltaic panel slides into or is in the U-shaped storage groove 32, the rotating roller 34 arranged at the bottom of the U-shaped storage groove 32 can rotate. On the one hand, it can reduce the friction between the photovoltaic panel and the U-shaped storage groove 32, and on the other hand, it can reduce the labor intensity of the loading work and improve the loading and unloading efficiency of the photovoltaic panel. After the photovoltaic panel enters the U-shaped storage groove 32, the U-shaped storage groove 32 is only covered on the aluminum alloy frame of the photovoltaic panel, which can reduce the volume of the U-shaped base strip 31 to reduce the weight of the device, and the movable end plate 1 and the fixed end plate 2 are located at both ends of several photovoltaic panel storage assemblies 3 to protect the inner area of the aluminum alloy frame of the photovoltaic panel.

[0048] Combine Figure 1 、 Figure 4 and Figure 5 As shown, the bottom of the movable end plate 1 and the fixed end plate 2 are respectively alternately provided with a first supporting member 4 and a second supporting member 5, and the first supporting member 4 and the second supporting member 5 are laterally slidably matched, so that the movable end plate 1 and the fixed end plate 2 can only slide in the direction toward or away from each other, and the upper and lower parts of the movable end plate 1, the fixed end plate 2 and several U-shaped base strips 31 are also provided with a scissor-type articulated frame 6, and the hinge axes of each middle hinge node 61 in the length direction of the scissor-type articulated frame 6 are respectively fixedly connected to the movable end plate 1, the fixed end plate 2 and several U-shaped base strips 31. During loading and unloading, the movable end plate 1 can slide back to back relative to the fixed end plate 2. During this process, the U-shaped base strips 31 can be moved synchronously by the linkage of the scissor-type hinged frame 6, thereby increasing the distance between adjacent U-shaped base strips 31 synchronously, making it convenient for workers to take out photovoltaic panels from the U-shaped storage groove 32 or put photovoltaic panels into the U-shaped storage groove 32 for storage; and during transportation, the movable end plate 1 can slide toward each other relative to the fixed end plate 2, so that the distance between adjacent U-shaped base strips 31 is reduced synchronously until the adjacent U-shaped base strips 31 abut against each other, thereby reducing the volume of the device and reducing the space occupied by the device (refer to Figure 5 shown).

[0049] Combine Figure 2 、 Figure 4 and Figure 5As shown, the interior of the U-shaped receiving groove 32 is also provided with a longitudinal clamping assembly and a transverse clamping assembly. Except for the U-shaped base strip 31 close to the movable end plate 1, the other two ends of the U-shaped base strips 31 are provided with a first sealing plate 314 on the side close to the movable end plate 1, and the fixed end plate 2 is provided with a second sealing plate 315 on the side close to the U-shaped base strip 31; during the sliding process of the movable end plate 1 and the fixed end plate 2 toward each other, when the scissors-type hinged frame 6 is retracted to the shortest distance, the first sealing plate 314 can be just attached to the two ends of the adjacent U-shaped base strip 31 to seal the opening 33 of its U-shaped receiving groove 32, and the second sealing plate 315 can be just attached to the two ends of the U-shaped base strip 31 close to the right end plate to seal the opening 33 of its U-shaped receiving groove 32. The longitudinal clamping assembly and the transverse clamping assembly can clamp the photovoltaic panel in the width direction and thickness direction respectively. After the photovoltaic panels are loaded, when the movable end plate 1 can slide toward each other relative to the fixed end plate 2, the length of the scissors-type articulated frame 6 begins to shrink. When several adjacent photovoltaic panel storage assemblies 3 are against each other, the length of the scissors-type articulated frame 6 shrinks to the shortest distance. At this time, the first sealing plate 314 can block the opening 33 of the adjacent U-shaped storage groove 32, and the second sealing plate 315 can block the opening 33 of the U-shaped storage groove 32 close to the right end plate, so that the photovoltaic panel is limited in the space surrounded by the U-shaped storage groove 32 and the first sealing plate 314 or the second sealing plate 315, and the longitudinal clamping assembly and the transverse clamping assembly can clamp the photovoltaic panel in the width direction and thickness direction respectively, so that the photovoltaic panel is firmly fixed to prevent the photovoltaic panel from moving during transportation.

[0050] This technical solution can enable the workers to slide the movable end plate 1 relative to the fixed end plate 2 in the process of loading and unloading photovoltaic panels, thereby increasing the distance between the movable end plate 1 and the fixed end plate 2, and further increasing the distance between adjacent photovoltaic panel storage assemblies 3, thereby facilitating the workers to load and unload photovoltaic panels, improving loading and unloading efficiency, and reducing the labor intensity of the workers. After the photovoltaic panels are loaded, the workers can slide the movable end plate 1 relative to the fixed end plate 2 in the process of sliding relative to the fixed end plate 2, thereby reducing the distance between the movable end plate 1 and the fixed end plate 2, and further enabling several adjacent photovoltaic panel storage assemblies 3 to abut against each other, reducing the volume of the device, thereby reducing the footprint of the device, and in the process of the movable end plate 1 sliding in the process of sliding relative to the fixed end plate 2, the gap of the U-shaped storage groove 32 can be automatically blocked, so that the longitudinal clamping assembly and the transverse clamping assembly can clamp the photovoltaic panel to prevent the photovoltaic panel from moving in the U-shaped storage groove 32 during transportation.

[0051] In this specific embodiment, the transverse clamping assembly includes a U-shaped clamping strip 81 arranged inside the U-shaped receiving groove 32 close to the side of the movable end plate 1, and the U-shaped clamping strip 81 close to the side of the movable end plate 1 is evenly and laterally provided with a resistance rod 82 that passes through the U-shaped base strip 31, and the resistance rod 82 is provided with a resistance block 83 on the side away from the U-shaped clamping strip 81, and a first return spring 84 is provided between the resistance block 83 and one side of the U-shaped base strip 31.

[0052] Based on the above design, initially, under the action of the first return spring 84, the U-shaped clamping strip 81 is tightly attached to the side wall of the U-shaped receiving groove 32. Figure 8 As shown, at this time, the thickness of the U-shaped storage groove 32 is greater than the thickness of the photovoltaic panel, so that the photovoltaic panel can slide in or out of the U-shaped storage groove 32 easily, thereby improving the loading and unloading efficiency of the photovoltaic panel. After the photovoltaic panel is loaded, when the movable end plate 1 moves relative to the fixed end plate 2, under the linkage action of the scissor-type articulated frame 6, several U-shaped base bars 31 move toward each other. At this time, the distance between adjacent U-shaped base bars 31 continues to decrease. When one side of the adjacent U-shaped base bar 31 contacts the interference block 83, the interference rod 82 causes the U-shaped clamping bar 81 to move toward the photovoltaic panel in the U-shaped storage groove 32. When the length of the scissor-type articulated frame 6 is retracted to the shortest distance, the U-shaped clamping bar 81 cooperates with the other side wall of the U-shaped storage groove 32 to complete the clamping of the photovoltaic panel in the thickness direction, thereby preventing the photovoltaic panel from moving during transportation. Furthermore, a first rubber pad can be placed on the U-shaped clamping bar 81 to prevent the rigid clamping from causing clamping damage to the aluminum alloy outer frame of the photovoltaic panel.

[0053] like Figures 9-11 As shown, in this specific embodiment, the longitudinal clamping assembly includes a first clamping structure and a second clamping structure arranged at the bottom and top of the U-shaped base strip 31, the first clamping structure includes a clamping block 71 arranged between adjacent rotating rollers 34 and vertically passing through the U-shaped base strip 31, and the end of the clamping block 71 away from the U-shaped receiving groove 32 is provided with a first inclined portion 72 facing the side of the opening 33 of the U-shaped receiving groove 32, and the clamping structure also includes a U-shaped frame 73 fixed to the bottom of the U-shaped base strip 31, and the inner side of the U-shaped frame 73 is slidably adapted to be fitted with a guide bar 74, and the top of the guide bar 74 corresponds to the clamping block 7 A second inclined portion 75 is provided that is in close contact with the first inclined portion 72 and connected to the first inclined portion 72 via a keyway. A partition plate 76 is provided at one end of the U-shaped frame 73 away from the opening 33 of the U-shaped receiving groove 32, and a second return spring 77 is provided on the partition plate 76 and the guide bar 74. A third inclined portion 78 is provided at one end of the guide bar 74 that is close to the opening 33 of the U-shaped base bar 31 and faces the fixed end plate 2. In a normal state of the return spring, the third inclined portion 78 of the guide bar 74 extends to the side of the U-shaped base bar 31 that is close to the opening 33. The second clamping structure is symmetrical to the first clamping structure and has the same structure.

[0054] Based on the above design, initially, under the action of the second return spring 77, the third inclined portion 78 of the guide bar 74 extends to the side of the U-shaped base bar 31 close to the opening 33. Figure 10 As shown, the top of the clamping block 71 of the first clamping structure is lower than the top height of the rotating roller 34, and the distance between the bottom of the clamping block 71 of the second clamping structure and the rotating roller 34 is greater than the width of the photovoltaic panel, which makes it convenient for the staff to slide the photovoltaic panel into or out of the U-shaped storage groove 32 with the help of the rotating roller 34, thereby improving the loading and unloading efficiency of the photovoltaic panel. After the photovoltaic panel is loaded, when the movable end plate 1 moves relative to the fixed end plate 2, under the linkage action of the scissor-type articulated frame 6, several U-shaped base strips 31 move toward each other. At this time, the distance between adjacent U-shaped base strips 31 continues to decrease. When the U When the first sealing plate 314 on the base bar 31 and the second sealing plate 315 on the fixed end plate 2 contact the third inclined surface of the guide bar 74, the guide bar 74 will be pushed to move toward the inside of the U-shaped frame 73. The guide bar 74 moves toward the inside of the U-shaped frame 73, and the cooperation between its second inclined surface 75 and the first inclined surface 72 of the clamping block 71 can make the clamping blocks 71 of the first clamping structure and the second clamping structure move toward each other to complete the clamping in the width direction of the photovoltaic panel. Furthermore, a second rubber pad can be provided on the clamping block 71 to avoid clamping damage to the aluminum alloy outer frame of the photovoltaic panel caused by hard clamping.

[0055] like Figure 12 and Figure 13 As shown, in this specific embodiment, the first supporting member 4 includes a first square hollow bar 41 symmetrically arranged at the bottom of the movable end plate 1, and the first square hollow bar 41 is arranged perpendicular to the movable end plate 1, and the second supporting member 5 includes a second square hollow bar 51 symmetrically arranged at the bottom of the fixed end plate 2, and the second square hollow bar 51 is arranged perpendicular to the fixed end, and the opposite sides of the two second square hollow bars 51 are respectively tightly attached to the opposite sides of the two first square hollow bars 41, and the second square hollow bar 51 is provided with a sliding groove 52 on the side close to the square hollow bar. The first square hollow bar 41 is provided with a slider 42 that passes through the sliding groove 52 and extends into the interior of the second square hollow bar 51, and the interior of the second square hollow bar 51 is rotatably provided with a screw 53 through a support shaft, and the screw 53 passes through the slider 42 and is threadedly engaged with the slider 42. The end of the screw 53 away from the fixed end plate 2 is transmission-connected to the rotating handle 55 fixed on the top of the second square hollow bar 51 through a bevel gear structure 54.

[0056] Based on the above design, when loading and unloading photovoltaic panels, the staff can drive the screw 53 to rotate by turning the rotating handle 55. Through the threaded cooperation between the screw 53 and the slider 42, the first square hollow bar 41 and the second square hollow bar 51 are moved toward or away from each other, so as to reduce the labor intensity of the staff. The screw 53 is self-locking. When the staff completes the distance adjustment between the fixed end plate 2 and the movable end plate 1, the relative position between the fixed end plate 2 and the movable end plate 1 can be fixed.

[0057] In addition, when transporting the device, the arm of a forklift can be extended into the first square hollow bar 41 to load the device into a vehicle box for stacking.

[0058] like Figure 13 As shown, in this embodiment, rollers 411 are evenly arranged along the length of the bottom of the first square hollow bar 41. When the first square hollow bar 41 and the second square hollow bar 51 move toward or away from each other, the rollers 411 move the first square hollow bar 41 to reduce friction.

[0059] In this embodiment, the top surfaces of the first square hollow bar 41 and the second square hollow bar 51 are flush with each other to form a smooth sliding surface, and the U-shaped frame 73 at the bottom of the U-shaped base bar 31 abuts against the sliding surface.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
