Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0018] In the description of this specification, the description with reference to the terms "this embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0019] like Figure 1-5 As shown, the present embodiment provides a photovoltaic output power short-term prediction self-test device, comprising a photovoltaic module 1, the photovoltaic module 1 comprising: a mounting bracket 2, a photovoltaic power generation panel 3, a hinge is installed between the upper end of the photovoltaic power generation panel 3 and the mounting bracket 2, a detection mounting frame 4 is installed on both sides of the center below the mounting bracket 2, a pull-out slide 401 is installed inside the detection mounting frame 4, the pull-out slide 401 is movably connected to the detection mounting frame 4, a detector 5 is installed on the upper surface of the pull-out slide 401, a spring 402 is connected between the inside of the detection mounting frame 4 and the pull-out slide 401, the spring 402 is fixedly connected to the pull-out slide 401 and the detection mounting frame 4, a winding roller 7 is installed inside the mounting bracket 2, an electric wire 403 is wound around the outer side of the winding roller 7, the electric wire 403 is electrically connected to the detector 5 and the photovoltaic power generation panel 3, an elastic rotating shaft 701 is connected between the winding roller 7 and the mounting bracket 2, and the winding roller 7 is rotatably connected to the mounting bracket 2 through the elastic rotating shaft 701.

[0020] like Figure 2-4As shown, in the present embodiment, an unfolding mechanism is installed between the photovoltaic panel 3 and the mounting bracket 2, and the unfolding mechanism includes: a first swing arm 201, a second swing arm 202, and a rotating ear plate 203. The first swing arm 201 is rotatably connected to the second swing arm 202, the second swing arm 202 is rotatably connected to the mounting bracket 2, the first swing arm 201 is rotatably connected to the photovoltaic panel 3, a hydraulic cylinder 204 is arranged between the rotating ear plate 203 and the mounting bracket 2, the hydraulic cylinder at the end of the hydraulic cylinder 204 is connected to the position of the second swing arm 202 with a swing ear plate, and a rotating ear plate is also installed between the other end of the hydraulic cylinder 204 and the mounting bracket 2, and side baffles 6 are installed on both side ends of the mounting bracket 2, and the side baffles 6 are fixedly connected to the mounting bracket 2.

[0021] The working principle of the present invention is as follows: when in use, the detector 5 is installed as a whole on the upper surface of the pull-out slide 401, and the power connection wire 403 between the detector 5 and the photovoltaic panel 3 is set to a relatively long margin and is wound on the outside of the winding roller 7 and then electrically connected to the detector 5 and the photovoltaic panel 3 respectively. When the photovoltaic panel 3 is used for photovoltaic power generation in daily life, the hydraulic cylinder 204 inside the two unfolding mechanisms is closed and controlled to work. After the hydraulic rod is pushed outward, the second swing arm 202 is controlled to rotate with the mounting bracket 2 as a whole. When the angle of the second swing arm 202 changes, the second swing arm 202 and the first swing arm 201 move, and the two photovoltaic panels 3 are controlled to rotate with the mounting bracket 2 through the hinges, and the unfolding angle is adjusted to perform photovoltaic power generation. At the same time, when the photovoltaic panel 3 is unfolded, the surplus of the power connection wire 403 wound on the winding roller 7 can be stretched, and at the same time When the photovoltaic panel 3 is unfolded from the outside of the mounting bracket 2, the pull-out slide 401 is pushed outward as a whole under the action of the spring 402 inside the detection mounting frame 4, so that the detector 5 can continuously detect the output power of the photovoltaic panel 3, and the staff can also quickly observe the detection results when patrolling. When encountering bad weather, the photovoltaic panel 3 is folded to the outside of the mounting bracket 2 as a whole by controlling the contraction of the hydraulic rod of the hydraulic cylinder 204. The folded photovoltaic panel 3 will contract the pull-out slide 401 as a whole to the inside of the detection mounting frame 4 to squeeze the spring 402, and at the same time, the power connection wire 403 will be rolled up under the action of the elastic rotating shaft 701, so that the longer power connection wire 403 can be prevented from being sheared and damaged by the folded first swing arm 201 and the second swing arm 202, and at the same time, the detector 5 can be prevented from being damaged as a whole under the action of the folded photovoltaic panel 3 and the side baffle 6.
