Description

Technical Field

[0001] This utility model belongs to the field of foldable photovoltaic panel technology, specifically a photovoltaic panel frame transportation vibration reduction and protection device. Background Technology

[0002] Solar photovoltaic (PV) systems, also known as photovoltaic systems, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. In recent years, due to the increased construction and investment in my country's power, telecommunications, mobile, and network infrastructure, traditional PV power stations are generally built outdoors and installed on the ground using brackets. Building PV power stations on the ground requires ground preparation, bracket erection, etc., resulting in long construction cycles and heavy workloads. Moreover, the division of labor among ground preparation, bracket installation, and PV panel installation is quite specialized, leading to many problems in the professional coordination during on-site construction. This has led to a demand for foldable PV systems that are easy to install and erect, used to support agricultural and water resource management programs, provide auxiliary power for construction sites, emergency areas, and off-grid charging stations, and can also serve as additional power sources to support existing generators or supply power to remote areas. Their ability to operate in both grid-connected and off-grid environments further expands their utility, meeting the needs of activities, venues, and communities that require reliable and sustainable power solutions.

[0003] During the transportation of foldable photovoltaic panels, vibration is inevitable, which can easily lead to damage to the photovoltaic panels due to collisions. In addition, when the photovoltaic panels are folded, the guide wheels bear the entire weight of the photovoltaic panels. The shaking and vibration of the vehicle during transportation will increase the stress on the guide wheels, which can easily cause the guide wheels to tilt and be damaged, affecting subsequent normal use. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model solves the following technical problem: by setting a top plate, the frame and the bottom of the photovoltaic panel can be abutted and fixed during transportation, avoiding excessive shaking of the frame and photovoltaic panel during transportation and reducing damage to the frame and photovoltaic panel due to vibration. By setting a top plate, the heavy pressure of the frame and photovoltaic panel on the hinge wheel is distributed, avoiding damage caused by a sudden increase in pressure on the hinge wheel during vibration. By setting a side pressure plate, after the bottom edge of the frame is abutted and fixed by the top plate, the side pressure plate abuts against the side walls at both ends of the frame, further stabilizing and fixing the frame and photovoltaic panel, preventing horizontal vibration of the frame and photovoltaic panel during transportation, and improving the stability of the frame and photovoltaic panel during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic panel frame transportation vibration damping and protection device, comprising a box body, wherein multiple frames are accommodated and arranged inside the box body, each frame surface is fixedly connected to a photovoltaic panel, the tops of each frame are hinged together by an upper hinge, and the bottoms of each frame are hinged together by a hinge wheel, a track is provided inside the box body at the bottom side of the hinge wheel, and two sets of mutually symmetrical vibration damping support components are respectively provided at the bottom of the box body at both ends of the frame.

[0006] Furthermore, the vibration damping support component includes a first bracket and a second bracket. Two sets of first brackets and second brackets are fixedly connected to the bottom side of the box body at both ends of the frame. Each first bracket and second bracket is arranged opposite to each other. A top plate for supporting the bottom edge of the frame is slidably connected between each set of first brackets and second brackets. Each first bracket and second bracket is provided with a sliding groove. A bolt fixedly connected to the top plate is slidably connected in each sliding groove. A lifting component is provided below each top plate.

[0007] Furthermore, the lifting component includes a slide rail, and a slide rail is fixedly connected inside the housing between each set of first and second supports. A slider is slidably connected on each slide rail, and multiple connecting rods are hinged to both sides of each slider. The top of each connecting rod is hinged to a corresponding bolt.

[0008] Furthermore, two sets of rod seats are fixedly connected at both ends of each top plate inside the box, and a threaded rod is rotatably connected between each set of rod seats. A threaded seat is fixedly connected to the top of each slider, and each threaded seat is threadedly connected to the corresponding threaded rod.

[0009] Furthermore, a handwheel is fixedly connected to one end of each threaded rod, and the end of each threaded rod passing through the handwheel is hexagonal prism-shaped.

[0010] Furthermore, each of the first brackets is disposed on the outer side of both ends of the frame, the height of each of the first brackets is higher than the lowest position of the frame, and a side pressure plate is rotatably connected to the top of each of the first brackets. The side of each side pressure plate near the frame is arc-shaped and can abut against the surface of both ends of the frame. A handle is fixedly disposed on the top of each side pressure plate.

[0011] Furthermore, one side of the box is provided with a door that can be opened from both sides.

[0012] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By setting the top plate, the frame and the bottom of the photovoltaic panel can be fixed together during transportation, so as to avoid excessive shaking of the frame and photovoltaic panel during transportation and reduce the problem of damage to the frame and photovoltaic panel due to vibration.

[0014] (2) By setting the top plate to distribute the pressure of the heavy frame and photovoltaic panel on the hinge wheel, the problem of damage caused by the sudden increase of pressure on the hinge wheel during vibration is avoided.

[0015] (3) By setting the side pressure plate, after the bottom edge of the frame is fixed by the top plate, the side pressure plate can be made to abut against the side walls at both ends of the frame, further stabilizing and fixing the frame and photovoltaic panel, avoiding horizontal vibration of the frame and photovoltaic panel during transportation, and improving the stability of the frame and photovoltaic panel during transportation.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1-6As shown, a photovoltaic panel frame transportation vibration reduction and protection device includes a box body 10, which houses multiple frames 12. The top and bottom of each frame 12 are hinged by an upper hinge 14 and a hinge wheel 15, respectively. A hinge wheel 15 is located at the bottom of the hinge wheel 15 inside the box body 10. A folding door 11 is provided on one side of the box body 10. Two sets of first brackets 17 and second brackets 18 are fixedly connected to the bottom of both ends of the frames 12 inside the box body 10. Two sets of vertical sliding grooves 19 are opened on each set of first brackets 17 and second brackets 18. A top plate 20 is slidably arranged between each set of first brackets 17 and second brackets 18. A bolt 21 is slidably arranged in each set of sliding grooves 19, and each bolt 21 is fixedly connected to the corresponding top plate 20.

[0025] By setting the top plate 20, the frame 12 and the bottom of the photovoltaic panel 13 can be abutted and fixed during transportation, avoiding excessive shaking of the frame 12 and the photovoltaic panel 13 during transportation, reducing the problem of damage to the frame 12 and the photovoltaic panel 13 due to vibration. In addition, by setting the top plate 20, the heavy pressure of the frame 12 and the photovoltaic panel 13 on the hinge wheel 15 is distributed, avoiding the problem of damage caused by a sudden increase in pressure on the hinge wheel 15 during vibration.

[0026] like Figure 1-6 As shown, a slide rail 24 is fixedly connected inside the housing 10 between each set of first brackets 17 and second brackets 18. A slider 23 is slidably connected on each slide rail 24. Two sets of connecting rods 22 are hinged to both sides of each slider 23. The top of each connecting rod 22 is hinged to the corresponding bolt 21. A threaded seat 25 is fixedly connected to the top of each slider 23. A set of rod seats 27 is fixedly connected to both ends of each top plate 20 inside the housing 10. A threaded rod 26 is rotatably connected between each set of rod seats 27. Each threaded rod 26 is threadedly connected to the two corresponding threaded seats 25.

[0027] By rotating the threaded rod 26 to drive the slider 23 to slide on the slide rail 24, the connecting rod 22 pushes the top plate 20 to rise along the direction of the slide groove 19, thereby enabling the top plate 20 to abut and support the frame 12 and the photovoltaic panel 13, or to lower the top plate 20 to release the support, so as to facilitate the unfolding and erection of the frame 12 and the photovoltaic panel 13.

[0028] Furthermore, the threaded connection between the threaded seat 25 and the threaded rod 26 provides a self-locking effect, ensuring that even if no external force is applied to the threaded rod 26 during transportation, the top plate 20 can always remain in an elevated state, stably supporting the bottom of the frame 12.

[0029] like Figure 1-6 As shown, each threaded rod 26 is fixedly connected to a handwheel 28 at one end near the box door 11, and the end of each handwheel 28 that passes through the center of gravity of the handwheel 28 is set as a hexagonal prism.

[0030] By setting the handwheel 28, the operator can easily turn the threaded rod 26, thereby enabling the operator to conveniently raise and lower the top plate 20. The hexagonal prism shape of the end of the threaded rod 26 allows the operator to continue turning the threaded rod 26 with a wrench or other tools after manually rotating it until the top plate 20 abuts against the frame 12, thus ensuring a tighter fit between the top plate 20 and the frame 12.

[0031] Meanwhile, operators can choose to use tools such as electric wrenches to connect the hexagonal prism end of the threaded rod 26 to the power tool, thereby achieving labor-saving and automatic driving of the lifting and lowering of the top plate 20, improving work efficiency and reducing labor intensity.

[0032] like Figure 1-6 As shown, each first bracket 17 is located on the outer side of both ends of the frame 12. The height of each first bracket 17 is higher than the lowest position of the frame 12. Each first bracket 17 is rotatably connected to a side pressure plate 29. The side of each side pressure plate 29 near the frame 12 is arc-shaped and can abut against the surfaces of both ends of the frame 12. Each side pressure plate 29 is fixedly provided with a handle 30 on its top.

[0033] By setting the side pressure plate 29, after the bottom edge of the frame 12 is fixed by the top plate 20, the side pressure plate 29 can abut against the side walls at both ends of the frame 12, further stabilizing and fixing the frame 12 and the photovoltaic panel 13, avoiding horizontal vibration of the frame 12 and the photovoltaic panel 13 during transportation, and improving the stability of the frame 12 and the photovoltaic panel 13 during transportation.

[0034] In this embodiment, initially, each top plate 20 is at a low position and has not yet abutted against the bottom edge of the frame 12, and each side pressure plate 29 is folded outward and in contact with the side wall of the frame 12.

[0035] Subsequently, the operator can manually turn the handwheel 28 or use a power tool to connect to the end of the threaded rod 26 and drive the threaded rod 26 to rotate. The threaded seat 25 will then drive the slider 23 to slide away from the handwheel 28. During this process, the connecting rod 22 will push the bolt 21 and the top plate 20 to slide upward along the direction of the slide groove 19 until the top plate 20 is stably and tightly abutted against the bottom edge of the frame 12, providing abutment support for the bottom side of the frame 12 and the photovoltaic panel 13, and sharing the pressure borne by the hinge wheel 15.

[0036] Then, the operator holds the handle 30 and flips the side pressure plate 29 until the side pressure plate 29 contacts the side walls at both ends of the frame 12 to support and fix the two ends of the frame 12. Then the box door 11 can be closed and the device can be loaded and transported.
