[0003] However, during snowy weather, the large contact area between the photovoltaic panels and the photovoltaic support structure makes these contact points prone to freezing when snow melts. This affects drainage during snowfall, impacting not only the normal operation of the equipment but also its lifespan. This impact is particularly severe for photovoltaic equipment in cold, snowy regions. Utility Model Content

Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1-3As shown, this embodiment provides a frost-resistant photovoltaic (PV) bracket, including a support frame with an inclined support surface and an assembly frame 2 disposed on the inclined support surface for assembling a PV panel 1. The upper end of the PV panel 1 is rotatably connected to the assembly frame 2. The lower ends of the PV panel 1 have corresponding pin holes 11 on opposite sides of the assembly frame 2. A PV panel adjustment mechanism is provided on the support frame and below the assembly frame 2. The PV panel adjustment mechanism includes a lifting device 3, a connecting rod assembly, and a pin 4. The lifting device 3 drives the pin 4 to extend and retract within the pin holes 11 via the connecting rod assembly. After the pin 4 extends out of the pin holes 11, the lifting device 3 lifts the lower end of the PV panel 1. Thus, in the initial state, the PV panel 1 is completely within the assembly frame 2, and the lower ends of the two are stably connected by the pin 4, allowing the PV panel 1 to be used normally. Before the snow melts, the lifting device 3 can be activated to lift the photovoltaic panel 1. The lifting device 3 first uses a connecting rod assembly to disengage the pins 4 on both sides from the photovoltaic panel 1. At this point, the lifting device 3 has not yet contacted or has just touched the lower side of the photovoltaic panel. Then, the lifting device 3 continues to lift, raising the lower end of the photovoltaic panel 1 a certain distance to create a gap between the lower end of the photovoltaic panel 1 and the mounting frame 2. This prevents freezing between the lower end of the photovoltaic panel 1 and the mounting frame 2, and also facilitates drainage. After the snow melts, the lifting device 3 is reset, and the photovoltaic panel 1 gradually returns to the mounting frame 2. Then, the lifting device 3 uses a connecting rod assembly to insert the pins 4 on both sides into the pin holes 11 of the mounting frame 2 and the photovoltaic panel 1, restoring a stable connection between the photovoltaic panel 1 and the mounting frame 2 for normal use.
[0029] The above mainly introduces the main concept of this embodiment. The specific structure used in this embodiment will be described below.
[0030] An extension frame 5 is provided between the lifting device 3 and the support frame to position the lifting device 3 below the photovoltaic panel 1. Figure 6 As shown, the lifting device 3 includes a guide cylinder 31, a lifting tube 32, a lead screw 33, and a motor 34. The guide cylinder 31 has guide grooves 311 along its length on both opposite sides. The lifting tube 32 has guide blocks 321 extending out of the guide grooves 311 on both opposite sides. The lifting tube 32 is slidably connected to the guide cylinder 31 and has internal threads. The motor 34 is located at the bottom of the guide cylinder 31, and the lead screw 33 is located at the motor output end and threadedly connected to the lifting tube 32. Thus, when the motor 34 drives the lead screw 33 to rotate, the lead screw 33 drives the lifting tube 32 to move up and down along the lead screw 33, achieving lifting and retraction actions. Although common cylinders and electric cylinders can also achieve lifting actions, this embodiment aims to achieve both photovoltaic panel lifting and pin insertion / removal actions with a single motor. Therefore, this device also requires guide blocks 321 extending out of the guide grooves 311 to drive the linkage assembly.
[0031] like Figure 4 As shown, the linkage assembly includes a traction plate 61, a guide structure 62, and a transmission rod 63. A pin 4 is mounted on the traction plate 61. The traction plate 61 is slidably connected to the guide structure 62 and moves along the guide structure. The two ends of the transmission rod 63 are rotatably connected to the traction plate 61 and the guide block 321, respectively. Thus, when the lifting tube 32 is lifted upwards, the guide block 321 moves upwards along the guide groove 311. Simultaneously, the guide block 321 pushes the traction plate 61 outwards via the transmission rod 63. The traction plate 61 moves horizontally outwards along the guide structure 62, thereby pulling the pin 4 out of the pin hole 11. Conversely, the traction plate 61 can insert the pin 4 into the pin hole 11.
[0032] like Figure 5 As shown, the guide structure 62 includes a guide bracket 621 and two guide rods 622 disposed within the guide bracket 621. The traction plate 61 is slidably connected to the guide rods 622, meaning the traction plate can translate along the guide rods. Of course, to improve the stability of the traction plate's movement, an additional guide bracket can be added. The four guide rods of the two guide brackets ensure the accuracy of the traction plate's movement path and guarantee that the pin can be accurately inserted into the pin hole.
[0033] Alternatively, a more stable but more costly solution could be to make the lifting action of the photovoltaic panel and the insertion / removal action of the pins structurally independent. The lifting action can be achieved using a conventional linear drive device such as a pneumatic or electric cylinder, while the insertion / removal of the pins on both sides can be achieved separately using a small pneumatic cylinder. For example, a small cylinder can be mounted on the lower side of the assembly frame, with its output end connected to the pins via a traction plate, controlling the pins' range of motion and maintaining the connection between the pins and the assembly frame. The pins are only allowed to extend and retract within the pin holes of the photovoltaic panel, ensuring the accuracy of the pin movements.
[0034] like Figure 1 As shown, the assembly frame 2 has a support plate 21 at its bottom, and a through hole 22 in the middle of the support plate 21. When the lower end of the photovoltaic panel 1 rests on the support plate 21, the pin hole 11 on the photovoltaic panel 1 is aligned with the pin hole on the assembly frame 2. The support plate 21 is used to ensure stable support for the photovoltaic panel 1 and to ensure that the pin 3 is accurately inserted into the pin hole 11, while the through hole 22 is used for drainage and heat dissipation.
[0035] The support frame includes two front columns 71, two rear columns 72, and a mounting frame mounted on the four columns. The rear columns 72 are higher than the front columns 71, giving the mounting frame an inclined support surface. Both the front columns 71 and the rear columns 72 include sleeves and telescopic tubes, each with multiple positioning holes 701 and positioning bolts 702. This allows the height of both the front columns 71 and the rear columns 72 to be adjusted to meet different installation requirements. Furthermore, both the front columns 71 and the rear columns 72 are rotatably connected to the mounting frame via universal joints 73, enabling height adjustments of the front columns 71 and rear columns 72 to regulate the tilt angle of the support surface and improve solar energy utilization. The mounting frame includes two crossbeams 732 and two diagonal beams 731. The assembly frame 2 is mounted on the two crossbeams 732, and there is a pin-operated space between the diagonal beams 731 and the assembly frame 2.
[0036] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
