Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a foldable photovoltaic component. Background Art

[0002] Photovoltaic modules, also known as solar modules, can convert the energy emitted by the sun into electrical energy, thereby achieving the effect of power generation. The output current of photovoltaic modules is proportional to the amplitude of sunlight exposure. The stronger the sunlight, the higher the output power of the module. As people's awareness of environmental protection continues to deepen, environmentally friendly power generation methods have gradually become popular.

[0003] The existing announcement number CN212588299U is a foldable portable photovoltaic module. This patent adopts photovoltaic panels articulated by hinges and support components for supporting each photovoltaic panel. The connecting parts arranged at the bottom of the photovoltaic panel are installed on two horizontal braces to form a stable support structure with a low front and a high rear. The purpose of using the photovoltaic module is achieved. The installation is quick and convenient, and the installation cost is reduced. When disassembling, the support component can be quickly disassembled and assembled and is easy to carry by simply folding it.

[0004] The inventors have found in their daily work that although the above-mentioned photovoltaic modules can be connected by hinges and folded together for easy folding and carrying, the photovoltaic modules are in an unfolded state during use. After long-term use, because the photovoltaic modules require frequent maintenance, if one of the photovoltaic modules is damaged, since they are hingedly connected, maintenance personnel need to use external tools to disassemble the hinge. This disassembly method is more troublesome and brings inconvenience to the maintenance work of the maintenance personnel. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems in the above background and to propose a foldable photovoltaic module.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a foldable photovoltaic assembly, comprising a first photovoltaic panel, a notch is provided on the surface of the first photovoltaic panel, a rotating rod is rotatably connected between the inner walls at both ends of the notch, a mounting device is provided on the outer wall surface of the rotating rod, the mounting device comprises a flip plate, the flip plate is fixedly mounted on the outer wall surface of the rotating rod, a limiting groove is provided on the surface of the flip plate, a limiting plate is movably mounted inside the limiting groove, and a second photovoltaic panel is fixedly mounted on one side surface of the limiting plate. The setting of the limiting plate and the limiting groove plays a preliminary effect of limiting the second photovoltaic panel and the flip plate.

[0007] Preferably, the surface of the limit plate is provided with a slide groove, two sliders are slidably connected inside the slide groove, a first spring is fixedly installed between the two sliders, an insertion rod is fixedly installed on the surface of the slider, and the inner wall surfaces on both sides of the limit groove are provided with insertion holes. The provision of the insertion rod and the insertion hole has the effect of limiting the limit plate inside the limit groove.

[0008] Preferably, one end of the slider away from the slide slot is hinged with a hinge plate, the end of the hinge plate away from the slider is hinged with a cross plate, and the end of the cross plate away from the hinge plate is fixed with a handle. The setting of the hinge plate plays an effect of driving the slider to move inside the slide slot.

[0009] Preferably, a limiting device is provided on the side of the first photovoltaic panel, and the limiting device includes a groove, and the groove is provided on the side of the first photovoltaic panel, and a displacement plate is slidably connected inside the groove, and a positioning rod is fixedly installed on the surface of the displacement plate, and a plurality of positioning holes are provided in an annular manner on the outer wall surface of the rotating rod. The arrangement of the positioning rod and the positioning holes has the effect of limiting the rotation of the rotating rod.

[0010] Preferably, an L-shaped rod is fixedly installed on the side of the first photovoltaic panel, an extension rod is slidably connected inside the L-shaped rod, and one end of the extension rod away from the L-shaped rod is fixedly connected to the displacement plate. The arrangement of the L-shaped rod and the extension rod allows the displacement plate to move stably.

[0011] Preferably, a second spring is fixedly mounted on the surface of one end of the displacement plate away from the positioning rod, and one end of the second spring away from the displacement plate is fixedly connected to the L-shaped rod. The second spring has the effect of limiting the position of the displacement plate inside the groove.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] When the second photovoltaic panel is damaged and needs maintenance, the handle is first pulled, and the movement of the handle drives the horizontal plate to move, and the movement of the horizontal plate drives the hinged plate to move. The hinged plate moves and pulls the two sliders to move in the direction of approaching each other inside the slide slot. The two sliders move in the direction of approaching each other inside the slide slot, which squeezes the first spring, causing the first spring to be compressed. At the same time, the two sliders move in the direction of approaching each other inside the slide slot and also drive the insertion rod to move. The insertion rod moves to move itself out of the inside of the insertion hole, and the insertion rod and the insertion hole are separated so that the limit plate loses its limit in the inside of the limit slot. At this time, the second photovoltaic panel can be moved, and the movement of the second photovoltaic panel drives the limit plate to move out of the inside of the limit slot, completing the disassembly operation of the second photovoltaic panel. Through the cooperation of the above structure, it is convenient to disassemble and assemble the first photovoltaic panel and the second photovoltaic panel, so that maintenance personnel can perform maintenance and replacement.

[0014] 2. In the utility model, by setting a limit device, when it is necessary to fold the first photovoltaic panel and the second photovoltaic panel, first slide the displacement plate to make the displacement plate move inside the groove. The movement of the displacement plate inside the groove will squeeze the second spring, so that the second spring is compressed. At the same time, the movement of the displacement plate inside the groove also drives the extension rod to move inside the L-shaped rod and also drives the positioning rod to move. The positioning rod moves to move itself out of the positioning hole, and the positioning rod and the positioning hole are separated to make the rotating rod lose the limit. At this time, the first photovoltaic panel and the second photovoltaic panel can be folded. After folding, the displacement plate is released, and the rebound force of the second spring is used to reset the positioning rod. The positioning rod is reset and then inserted into the corresponding positioning hole to re-limit the rotation of the rotating rod. Through the cooperation of the above structure, the purpose of limiting the rotating rod is achieved, and it is avoided that the rotating rod rotates after the first photovoltaic panel and the second photovoltaic panel are folded, resulting in folding failure.

A plurality of positioning holes 54 are annularly opened on the outer wall surface of the rotating rod 3. When the first photovoltaic panel 1 and the second photovoltaic panel 404 need to be folded, the displacement plate 52 is first slid to move the displacement plate 52 inside the groove 51. The movement of the displacement plate 52 inside the groove 51 will squeeze the second spring 57, so that the second spring 57 is compressed. At the same time, the movement of the displacement plate 52 inside the groove 51 also drives the extension rod 56 to move inside the L-shaped rod 55, and also drives the positioning rod 53 to move. The positioning rod 53 moves to move itself out of the positioning hole 54, and the positioning rod 53 and the positioning hole 54 are separated to make the rotating rod 3 lose the limit.

The movement of the insertion rod 407 makes it move out from the inside of the socket 408. The separation of the insertion rod 407 and the socket 408 makes the limiting plate 403 lose its limit in the limiting groove 402. At this time, the second photovoltaic panel 404 can be moved.

When the first photovoltaic panel 1 and the second photovoltaic panel 404 need to be folded, the displacement plate 52 is first slid to move the displacement plate 52 inside the groove 51. The movement of the displacement plate 52 inside the groove 51 will squeeze the second spring 57, so that the second spring 57 is compressed. At the same time, the movement of the displacement plate 52 inside the groove 51 also drives the extension rod 56 to move inside the L-shaped rod 55, and also drives the positioning rod 53 to move. The positioning rod 53 moves to move itself out of the positioning hole 54, and the positioning rod 53 and the positioning hole 54 are separated to make the rotating rod 3 lose the limit. At this time, the first photovoltaic panel 1 and the second photovoltaic panel 404 can be folded. After folding, the displacement plate 52 is released, and the rebound force of the second spring 57 is used to reset the positioning rod 53.
