Photovoltaic panels are mainly composed of semiconductor materials, and their basic technology is solar cell technology. Photovoltaic panels can be mainly divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon solar panels according to materials. Monocrystalline silicon photovoltaic panels have the highest conversion efficiency and the most mature technology, and are the mainstream development direction.

As a result, when the photovoltaic panels are set in different scenes, the angle and intensity of sunlight will change, and the photovoltaic panels cannot adjust the angle in time. The unreasonable angle setting may cause reflection and loss of sunlight, thereby reducing the effect of energy conversion and poor power generation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a photovoltaic panel frame structure that is convenient for adjusting the angle of a photovoltaic panel, comprising a base 100 and a main frame 102, two first support rods 101 are fixedly connected to one side of the top surface of the base 100, and two second support rods 200 are fixedly connected to the other side of the top surface of the base 100, an empty groove 204 is opened inside the second support rod 200, a lifting screw 201 is arranged inside the second support rod 200, a lifting assembly for adjusting the angle of the main frame 102 is arranged at the bottom of the lifting screw 201, the top of the first support rod 101 and the lifting screw 201 are both movably connected with a hinge 203, the hinge 203 is fixedly connected to the main frame 102, and clamping assemblies for fixing the photovoltaic panel are symmetrically fixedly installed on both sides of the main frame 102.

[0020] Specifically, the photovoltaic panel is first placed on the top surface of the main frame 102, and the photovoltaic panel is clamped and fixed by the clamping assembly, so that when the photovoltaic panel is placed outdoors, it can remain stably fixed to the frame even in severe weather such as strong winds, and will not fall off and cause damage. When the angle of the photovoltaic panel needs to be adjusted, the height of the lifting screw 201 is adjusted by the lifting assembly. When the lifting screw 201 is upward, the hinge 203 at the top of the lifting screw 201 is tilted at an angle, and pushes the bottom surface of one end of the main frame 102 to gradually tilt it. At this time, the height of the lifting screw 201 is higher than the first support rod 101. Since the upper end surface of the main frame 102 is raised, the lower end surface is subjected to force and compresses the hinge 203 at the top of the first support rod 101 to tilt at an angle, thereby realizing the adjustment of the angle of the photovoltaic panel. The photovoltaic panel can adjust its angle so that it can better receive sunlight, reduce the loss of solar energy, further improve the effect of energy conversion, and also improve the power generation efficiency.

[0021] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, the lifting assembly includes two third support rods 300 fixed on the top surface of the base 100 and a worm gear 202 rotatably connected to the top of the second support rod 200, the worm gear 202 is threadedly connected to the lifting screw 201, the two third support rods 300 are symmetrically arranged, the tops of the two third support rods 300 are fixedly connected with a casing 301, the opposite sides of the two casings 301 are rotatably connected with a worm 302, one end of the worm 302 extends to the outside of the casing 301 and the end is fixedly connected with a handle 303, and the worm 302 is transmission-connected to the two worm gears 202.

[0022] Specifically, when the angle of the photovoltaic panel needs to be adjusted, the handle 303 is turned. Since one end of the worm 302 is fixedly connected to the rotating handle 303, and the other end is rotatably connected to the casing 301 through a bearing, when the handle 303 is turned, the worm 302 is driven to start rotating, and the two ends of the worm 302 are meshed with the worm wheel 202, thereby driving the worm wheel 202 to rotate. Since the worm wheel 202 is threadedly connected to the lifting screw 201, the lifting screw 201 is driven to rise and lift the bottom surface of the main frame 102, causing it to tilt at an angle.

[0023] Furthermore, the bottom surface of the worm gear 202 is rotatably connected to the second support rod 200, and the second support rod 200 is fixed to the top surface of the base 100. Therefore, when the worm gear 202 rotates, the second support rod 200 does not rotate, and the worm gear 202 always rotates at the top end of the second support rod 200 and does not detach from it.

[0024] As an implementation method in this embodiment, Figure 2 and Figure 4 As shown, the clamping assembly includes a clamping plate 400 , the top surface of the clamping plate 400 is threadedly connected to a clamping screw 402 , the top end of the clamping screw 402 is fixedly connected to a knob 403 , and the bottom end of the clamping screw 402 is fixedly connected to a pressure plate 404 .

[0025] Specifically, when placing the photovoltaic panel, place the side of the photovoltaic panel under the pressure plate 404, turn the knob 403, and the knob 403 drives the clamping screw 402 to move downward. At this time, the pressure plate 404 follows the clamping screw 402 to move downward, clamping the side of the photovoltaic panel, so that the photovoltaic panel is stably fixed on the main frame 102.

[0026] As an implementation method in this embodiment, Figure 4As shown, the inner wall of the clamping plate 400 is provided with a limiting groove 401, and the inner side of the pressure plate 404 is fixedly connected with a limiting slider 405 adapted to the limiting groove 401, and the limiting slider 405 is slidably connected to the limiting groove 401, and the limiting slider 405 and the limiting groove 401 limit the up and down movement of the pressure plate 404 to prevent it from rotating with the clamping screw 402, so that the pressure plate 404 can stably clamp the photovoltaic panel vertically downward in the current form.

[0027] As an implementation method in this embodiment, Figure 3 As shown, the inner diameter of the empty slot 204 is larger than the outer diameter of the lifting screw 201 . The empty slot 204 is used to accommodate the lifting screw 201 . When the lifting screw 201 descends, the bottom end of the lifting screw 201 is retracted into the empty slot 204 .

[0028] As an implementation method in this embodiment, Figure 3 As shown, the bottom end of the worm wheel 202 is rotatably connected to the top end of the second support rod 200 via a bearing, and the inner wall of the worm wheel 202 is threadably connected to the lifting screw 201 via a thread. It should be noted here that the worm wheel 202 and the second support rod 200 are separate parts, and the worm wheel 202 is set at the top end of the second support rod 200 via a bearing and rotates via the bearing. It is not sleeved on the second support rod 200, and the position of the worm wheel 202 is always fixed and will not move with the movement of the lifting screw 201.

[0029] Working principle: Place the photovoltaic panel on the top surface of the main frame 102, place the side of the photovoltaic panel under the pressure plate 404, turn the knob 403, the knob 403 drives the clamping screw 402 to move downward, and the pressure plate 404 moves downward with the clamping screw 402 to clamp the side of the photovoltaic panel. The worm 302 starts to rotate by turning the handle 303. The two ends of the worm 302 are meshed with the worm wheel 202, thereby driving the worm wheel 202 to rotate. Since the worm wheel 202 is threadedly connected to the lifting screw 201, the lifting screw is driven. 201 rises to lift the bottom surface of the main frame 102. When the lifting screw 201 moves upward, the hinge 203 at the top of the lifting screw 201 tilts at an angle and pushes the bottom surface of one end of the main frame 102 to gradually tilt. At this time, the height of the lifting screw 201 is higher than the first support rod 101. As the upper end surface of the main frame 102 rises, the lower end surface is subjected to force and presses the hinge 203 at the top of the first support rod 101 to tilt at an angle, so that the main frame 102 maintains the current angle, thereby realizing the adjustment of the angle of the photovoltaic panel.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
