Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic boxes, in particular to a high-protection stainless steel photovoltaic box. Background Art

[0002] A photovoltaic combiner box means that users can connect a certain number of photovoltaic cells of the same specifications in series to form photovoltaic strings, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After the photovoltaics are combined in the photovoltaic combiner box, they are used in conjunction with a controller, a DC distribution cabinet, a photovoltaic inverter, and an AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection with the city power grid.

[0003] The existing Chinese patent application number: 202221708260.0 discloses a photovoltaic box, including a photovoltaic junction box body, and an upper hanging rod and a lower hanging rod fixed on a photovoltaic bracket. The photovoltaic box also includes an upper connecting plate, a lower connecting plate, a No. 1 manual bolt, a No. 2 manual bolt and: a mounting plate. Two "mouth"-shaped mounting plates are symmetrically fixed on the back of the photovoltaic junction box body. The two ends of the upper connecting plate and the lower connecting plate respectively pass through the two mounting plates, and a vertical long waist hole is opened on the mounting plate. The No. 1 manual bolt passes through the vertical long waist hole and is connected to the upper connecting plate by a threaded screwing method. The No. 2 manual bolt passes through the vertical long waist hole and is connected to the lower connecting plate by a threaded screwing method.

[0004] When the above technology is in use, through the setting of multiple hanging plates, personnel can install the photovoltaic box by hanging the box on each hanging rod through the hanging plates. However, in actual use, since there are no protective components on the outside of the box, when the photovoltaic box accidentally encounters sudden weather changes such as hail outdoors, the falling hail directly falls on the photovoltaic box, thereby damaging the photovoltaic box, which increases economic losses. In addition, when installing the box through the hanging plates, personnel also need to adjust the position of the hanging plates through multiple bolts, which makes the box inconvenient to install. Therefore, in order to solve the defects of the photovoltaic box lacking protective components and inconvenient installation in the above technology, we propose a high-protection stainless steel photovoltaic box.

[0015] 1: In the utility model, the outer shell of the photovoltaic box is made of stainless steel, which effectively improves the anti-rust, anti-collision and other protective effects of the photovoltaic box. The protective plate and the top spring cooperate with each other, so that when an external object hits the upper surface of the protective plate, the protective plate compresses the top spring, thereby achieving a buffering effect, that is, reducing the impact force transmitted to the internal components of the photovoltaic box when the object hits the protective plate, thereby reducing the phenomenon of damage to the internal components of the photovoltaic box due to impact, that is, further improving the protective effect of the photovoltaic box, and through the setting of the elastic band and the clamping plate, when personnel face hanging rods with different spacings during the installation of the photovoltaic box, they can directly pull the clamping plate, that is, avoiding the phenomenon that personnel in the traditional solution need to remove the bolts before moving the corresponding parts, thereby achieving adaptation to the spacing of the hanging rods, that is, when this solution is used, personnel can install and disassemble the photovoltaic box more easily and conveniently.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all of the embodiments.

[0025] Example 1

[0026] Reference Figure 1-6 A high-protection stainless steel photovoltaic box includes a box body 1, a box door is provided on the front side of the box body 1, a plurality of pipes for passing cables are provided on the lower side of the box body 1, mounting blocks 2 are fixed to the upper ends of both sides of the box body 1, linkage rods 3 are slidably installed at both ends of the mounting blocks 2, the upper ends of the linkage rods 3 extend to the top of the box body 1 and are jointly fixed with a protective plate 4, the linkage rod 3 is located between the mounting block 2 and the protective plate 4 and is sleeved with a top spring 15, a hanging plate 5 is fixed to the upper end of the rear side of the box body 1, a clamping plate 6 is slidably installed on the lower end of the rear side of the box body 1 through a guide assembly, and the hanging plate 5 is connected to the clamping plate 6 A receiving groove corresponding to the external hanging rod is provided on the side close to it, and a holding piece 7 is provided between the hanging plate 5 and the clamping plate 6. The holding piece 7 is a common elastic belt or tension spring, etc. An auxiliary component is provided on the lower surface of the clamping plate 6. The protective plate 4 and the box body 1, the box door, the hanging plate 5 and the clamping plate 6 are all made of stainless steel, and an insulating layer can be applied on the surface of the stainless steel parts according to specific usage requirements. Since the shell and other parts outside the photovoltaic box are made of stainless steel, the photovoltaic box is not easily damaged when an external object accidentally hits the photovoltaic box, so that the photovoltaic box has a better protective effect.

[0027] Example 2

[0028] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0029] The auxiliary components include a fixed frame 8, a linkage shaft 9, a force rod 10 and a traction belt 11. The fixed frame 8 is fixed to the lower end of the rear side of the box body 1, the linkage shaft 9 is rotatably installed at the end of the fixed frame 8 away from the box body 1, the force rod 10 is arranged at both ends of the linkage shaft 9, the upper end of the traction belt 11 is installed on the lower surface of the clamping plate 6, and the lower end of the traction belt 11 is wound and installed on the middle part of the rod body of the linkage shaft 9. The setting of the auxiliary components enables the personnel to drive the linkage shaft 9 to rotate through the force rod 10 when pulling the clamping plate 6, and the traction belt 11 is wound when the linkage shaft 9 rotates, that is, the traction belt 11 is wound. The movable clamping plate 6 moves downward, thereby expanding the gap between the clamping plate 6 and the hanging plate 5, so that personnel can easily pull the clamping plate 6 to facilitate the installation and disassembly of the photovoltaic box; connecting blocks are fixed at both ends of the linkage shaft 9, and the force rod 10 is slidably connected to the connecting block. Spherical anti-falling protrusions are provided at both ends of the force rod 10. The setting of the connecting block allows personnel to move the position of the force rod 10, thereby allowing personnel to drive the linkage shaft 9 more labor-saving, and the setting of the anti-falling protrusion effectively prevents the force rod 10 from falling off from the connecting block.

[0030] A plurality of hooks 12 are installed on the lower surface of the hanging plate 5 and the upper surface of the clamping plate 6. The two ends of the pulling member 7 are sleeved on the corresponding hooks 12. The setting of the hooks 12 makes it convenient for personnel to install and replace the pulling member 7, and personnel can set different numbers of pulling members according to the weight of the photovoltaic box and the distance from the external hanging rod, so that the force applied by the clamping plate 6 to the external hanging rod forms a corresponding balance with the structural strength of the hanging rod itself, that is, it avoids the phenomenon that the clamping plate 6 is clamped too loosely, resulting in poor stability of the photovoltaic box after installation, and it also avoids the phenomenon that the clamping plate 6 is clamped too tightly, resulting in deformation of the external hanging rod; the guide assembly includes two guide rods 13, the upper ends of the guide rods 13 are fixed to the lower surface of the hanging plate 5 The lower end of the guide rod 13 is fixed to the lower end of the rear side of the box body 1 through a fixing block, and the two ends of the clamping plate 6 are slidably sleeved on the rod body of the guide rod 13. The setting of the guide rod 13 is convenient for providing a moving guiding effect for the clamping plate 6. The lower end of the connecting rod 3 located in the same mounting block 2 is jointly fixed with a limiting plate 14, and the connecting rod 3 and the mounting block 2 are installed through a sliding bearing. The setting of the limiting plate 14 avoids the accidental separation between the connecting rod 3 and the mounting block 2; the middle part of the upper surface of the protective plate 4 is in an upward convex state, and the upper surface of the protective plate 4 is a smooth surface. The upper surface is a smooth surface and the middle part of the protective plate 4 is upwardly convex, so that external hail and the like can quickly slide off the upper surface of the protective plate 4.

[0031] When the cam 12 is in operation, the cam 12 is released, and the clamping plate 6 is quickly moved toward the hanging rod under the elastic force of the holding member 7, until the clamping plate 6 is clamped on the outside of the hanging rod at the bottom, that is, the hanging plate 5 and the clamping plate 6 are respectively clamped on the sides of the two hanging rods, and in this process, the clamping plate 6 is under the action of the holding member 7. The protective plate 4 can be lifted up by the top spring 15 when the upper surface of the protective plate 4 is not hit, that is, there is a gap between the protective plate 4 and the upper surface of the box body 1, and when hail or other objects fall suddenly from the outside, the objects first fall onto the surface of the protective plate 4, thereby avoiding the objects from directly hitting the upper surface of the box body 1 and causing damage thereto, and because the protective plate 4 and the mounting block 2 are slidably connected, that is, after the object hits the upper surface of the protective plate 4, the protective plate 4 compresses the top spring 15 and pushes the connecting rod 3 to move downward, and in this process, the top spring 15 absorbs the potential energy of the protective plate 4 by deformation, thereby reducing the impact force transmitted to the box body 1 when the object hits the protective plate 4, thereby further improving the protection effect of the internal components of the photovoltaic box.

[0032] It should be further explained that the setting of the auxiliary component amplifies the force applied by personnel to the linkage shaft 9, so that personnel can conveniently and labor-savingly reel in the traction belt 11, that is, it is convenient for personnel to pull the clamping plate 6, thereby allowing personnel to conveniently pull the clamping plate 6 to facilitate installation and disassembly of the photovoltaic box. The setting of the connecting block allows personnel to move the position of the force rod 10, thereby allowing personnel to drive the linkage shaft 9 more labor-savingly, and the setting of the anti-fall-off protrusion effectively prevents the force rod 10 from falling off from the connecting block. The setting of the hook 12 makes it convenient for personnel to install and replace the holding member 7, and personnel can set different numbers of holding members according to the weight of the photovoltaic box and the distance from the external hanging rod, so that the force applied by the clamping plate 6 to the external hanging rod forms a corresponding balance with the structural strength of the hanging rod itself, that is, it avoids the phenomenon that the clamping plate 6 is clamped too loosely, resulting in poor stability of the photovoltaic box after installation, and it also avoids the phenomenon that the clamping plate 6 is clamped too tightly, resulting in deformation of the external hanging rod; the protective plate 4 with a smooth upper surface and an upward protrusion in the middle allows external hail and the like to quickly slide off the upper surface of the protective plate 4.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
