Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel installation and storage, and in particular to an electrically controlled storage and extension bracket used for outdoor photovoltaic panels. Background Art

[0002] Photovoltaic panels are a type of power generation equipment that converts solar energy into electrical energy. Because of their simple structure, long life, and easy installation and use, they are widely used in remote areas, areas without access to the power grid, and industrial production enterprises. However, the current conversion efficiency of photovoltaic panels is still relatively low, resulting in the need to lay a large area. Moreover, they are mostly laid in remote and high-altitude areas, which makes their later maintenance and early transportation difficult and costly, and they cannot be stored autonomously in harsh environments. They need to be cleaned and maintained regularly, resulting in high later use costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the current photovoltaic panels are difficult and costly to maintain in the later stage and to transport in the early stage, and cannot be stored autonomously in harsh environments and need to be cleaned and maintained regularly, resulting in very high subsequent use costs.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an electrically controlled retractable and deployable bracket applied to outdoor photovoltaic panels, comprising an external frame supported by aluminum alloy, an external waterproof cover plate fixedly mounted on the outside of the external frame, an electrically controlled lifting and flipping frame movably mounted on the inside of the external frame, a four-folding assembly frame movably mounted on the inside of the electrically controlled lifting and flipping frame for installing photovoltaic panels, an upper closing cover plate for closing the upper opening of the external frame elastically mounted on the upper end of the middle folding end of the four-folding assembly frame, and lateral flipping stabilizing brackets movably mounted on both sides of the external waterproof cover plate.

[0005] The inner wall of the outer frame is symmetrically provided with inner guide rails for improving the lifting stability of the electrically controlled lifting and flipping frame.

[0006] The electrically controlled lifting and flipping frame comprises a longitudinal screw rod movably mounted in the inner guide rail, an internal thread adjustment block threadedly sleeved on the longitudinal screw rod, a transverse assembly shaft mounted on the internal thread adjustment block and a movable folding frame movably sleeved on the transverse assembly shaft.

[0007] A lateral translation guide rail is fixedly mounted on the upper surface of the movable folding frame.

[0008] The lateral translation guide rail is internally movably equipped with an internal electric control lead screw for controlling the four-fold assembly frame and an internal thread translation block threadedly assembled on the outside of the internal electric control lead screw.

[0009] The four-folding assembly frame comprises a first assembly frame, a second assembly frame, a third assembly frame and a fourth assembly frame which are movably connected via axes.

[0010] The first assembly frame and the fourth assembly frame are both fixedly assembled with the internal thread translation block.

[0011] A lateral flip opening matched with the lateral flip stabilizing bracket is provided on the outer side surface of the external waterproof cover plate.

[0012] The lateral flipping stabilizing bracket comprises a flipping closing plate movably mounted at the lateral flipping opening, a telescopic box fixed on the inner side of the flipping closing plate, a flipping support rod movably mounted on the side wall of the external frame and a telescopic extension support rod fixed inside the telescopic box.

[0013] A pressure sensing module is fixedly mounted on the side wall of the external waterproof cover plate.

[0014] The beneficial effects of the present invention are:

[0015] (1) The electrically controlled retractable bracket for outdoor photovoltaic panels of the present invention adopts a retractable structure design, which can completely retract the external structure into the external frame, thereby greatly improving the safety and durability of the equipment;

[0016] (2) By lowering the photovoltaic panel in a harsh environment and folding it for storage, external impurities can be prevented from accumulating on the surface of the photovoltaic panel, thus extending its maintenance cycle and reducing the cost of later use;

[0017] (3) An electrically controlled lifting and flipping frame is movably mounted inside the outer frame, and the four-folding assembly frame can be lifted to the upper opening position through lifting and adjustment, which is convenient for later unfolding and increases the unfolding area;

[0018] (4) By adopting a smaller footprint to obtain a larger deployment area, it is not only convenient for assembly, but also reduces the space occupied by storage and transportation, thereby reducing costs;

[0019] (5) By movably assembling lateral flip stabilizing brackets on both sides of the external waterproof cover plate, the lateral support force and stability of the entire device can be improved;

[0020] (6) After the bracket is stored, a closed space will be formed, which greatly improves the safety and durability of the photovoltaic panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figure 1 , Figure 2 and Figure 3 An electrically controlled stowage and extension bracket for outdoor photovoltaic panels is shown, comprising an external frame 1 supported by aluminum alloy, an external waterproof cover plate 2 being fixedly mounted on the outer side of the external frame 1, an electrically controlled lifting and flipping frame 3 being movably mounted inside the external frame 1, a four-folding assembly frame 4 for installing photovoltaic panels being movably mounted inside the electrically controlled lifting and flipping frame 3, an upper closing cover plate 5 for closing the upper opening of the external frame 1 being elastically mounted on the upper end of the middle folding end of the four-folding assembly frame 4, and lateral flipping stabilizing brackets 6 being movably mounted on both sides of the external waterproof cover plate 2.

[0028] Working principle: Under sufficient light conditions, the electrically-controlled lifting and flipping frame 3 is lifted and flipped to become a plane, and then the four-folding assembly frame 4 is translated and unfolded outward on the upper surface of the flattened electrically-controlled lifting and flipping frame 3, eventually forming a larger frame, and then the four photovoltaic panels installed on the four-folding assembly frame 4 are used to generate electricity.

[0029] For the convenience of control, light intensity and rainfall sensors are installed on the upper surface of the upper closed cover plate 5 .

[0030] In order to improve the guiding performance during the lifting process, inner guide rails 7 for improving the lifting stability of the electrically-controlled lifting and flipping frame 3 are symmetrically installed on the inner wall of the outer frame 1 .

[0031] In order to cooperate with the lifting and lowering adjustment, the electrically controlled lifting and flipping frame 3 includes a longitudinal screw rod 31 movably assembled in the inner guide rail 7, an internal thread adjustment block 32 threadedly sleeved on the longitudinal screw rod 31, a transverse assembly shaft 33 installed on the internal thread adjustment block 32, and a movable folding frame 34 movably sleeved on the transverse assembly shaft 33.

[0032] The longitudinal screw rod 31 drives the internal thread adjustment block 32 to be raised and lowered along the inner guide rail 7 by rotating, thereby controlling the lifting and lowering adjustment of the movable folding frame 34. When the movable folding frame 34 is lifted to the upper opening position, the two sides of the movable folding frame 34 are flipped outward and unfolded until the movable folding frame 34 is fully unfolded into a plane.

[0033] In order to improve the guiding performance of the surface adjustment, a lateral translation guide rail 8 is fixedly mounted on the upper surface of the movable folding frame 34 .

[0034] In order to cooperate with the translational unfolding, the lateral translation guide rail 8 is internally movably equipped with an internal electric control screw rod 9 for controlling the four-folding assembly frame 4 and an internal thread translation block 10 threadedly assembled on the outside of the internal electric control screw rod 9 .

[0035] The internal electric control screw 9 controls the internal thread translation block 10 to adjust along the lateral translation guide rail 8 by rotating.

[0036] In order to cooperate with folding and turning, the four-folding assembly frame 4 includes a first assembly frame 41, a second assembly frame 42, a third assembly frame 43 and a fourth assembly frame 44 which are movably connected through axes.

[0037] In order to cooperate with the thread adjustment, the first assembly frame 41 and the fourth assembly frame 44 are both fixedly assembled with the internal thread translation block 10 .

[0038] In order to cooperate with the flipping adjustment, a lateral flipping opening that cooperates with the lateral flipping stabilizing bracket 6 is opened on the outer side surface of the external waterproof cover plate 2.

[0039] In order to cooperate with lateral flipping and extension support, the lateral flipping stabilization bracket 6 includes a flip closing plate 61 movably installed at the lateral flipping opening, a telescopic box 62 fixed on the inner side of the flip closing plate 61, a flip support rod 63 movably installed on the side wall of the external frame 1 and a telescopic extension support rod 64 fixed inside the telescopic box 62.

[0040] The flip support rod 63 controls the flipping adjustment of the flip closing plate 61 and the telescopic box 62 by telescoping, while the telescopic extension support rod 64 contacts the lateral ground by telescoping, thereby increasing the lateral supporting force.

[0041] In order to monitor the pressure in different directions and thus facilitate the control of the bracket, a pressure sensing module 11 is fixedly mounted on the side wall of the external waterproof cover plate 2 .

[0042] When the pressure sensing module 11 senses that the pressure on one side is much greater than the pressure at other positions, it will activate the flip support rod 63 and the telescopic extension support rod 64 on the opposite side, thereby increasing the rear support force to prevent the external frame 1 from tipping over.

[0043] The flip support rods 63 and the telescopic extension support rods 64 on both sides can also be activated to form a lateral support frame structure.

[0044] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
