SPECIFIC EMBODIMENTS

[0017] The present invention is described in detail below with reference to the attached drawings and in conjunction with embodiments.

[0018] The present invention proposes a hand-cranked photovoltaic mobile integrated trailer that maximizes solar energy output by manually adjusting angles of photovoltaic panels. Simultaneously, the present invention introduces a power system that not only achieves mains charging but also enables mains power output, serving as an emergency power source.

[0019] As shown in FIG. 1, a hand-cranked photovoltaic mobile integrated trailer of the present invention, comprises a monitoring and lighting assembly 1, a lifting rod assembly 2, a chassis frame assembly 3, an adjustable photovoltaic assembly 4, a power system 5, and a storage box 6.

[0020] As shown in FIG. 2, the monitoring and lighting assembly 1 comprises monitoring cameras 101, a lighting fixture 102, a sound amplification device 103, and a cloud computing data processing control box 104.

[0021] As shown in FIG. 3, the lifting pole assembly 2 comprises a lifting rod 201, a hand-cranked rotating rope structure 202, and a photovoltaic panel docking platform 203.

[0022] As shown in FIG. 4, the chassis frame assembly comprises a vehicle chassis 301, a guide wheel 302, four supporting legs 303, and a frame structure 304.

[0023] As shown in FIG. 5, the adjustable photovoltaic assembly 4 comprises photovoltaic panels 401, a photovoltaic bracket 402, and a hand-cranked photovoltaic rotating support 403.

[0024] As shown in FIG. 6, a power system comprises an electrical box 501, an MPPT controller 502, an AC/DC controller 503, a DC/DC voltage stabilizing controller 504, a DC/AC controller 505, a battery energy storage assembly, a photovoltaic access switch S1, and a monitoring and lighting assembly power supply switch S2.

[0025] The monitoring and lighting assembly 1 of the present invention meets multi-directional monitoring requirements through the monitoring cameras 101, and achieves functions of lighting and sound amplification through the lighting fixture 102 and the sound amplification device 103. All data transmission of the present invention is stored in the cloud computing data processing control box 104. During the driving of the hand-cranked photovoltaic mobile integrated trailer of the present invention, the monitoring and lighting assembly 1 is disassembled and placed in the storage box 6.

[0026] The lifting rod assembly 2 and the monitoring lighting assembly 1 is connected via a quick-connect interface, and the lifting rod 201 is raised and lowered by the hand-cranked rotating rope structure 202, which comprises a self-locking function.

[0027] The chassis frame assembly 3 is fixed to the lifting rod assembly 2 by bolt connection. During driving, the chassis frame assembly 3 releases the guide wheel 302 and meanwhile retracts the four supporting legs 303; when the hand-cranked photovoltaic mobile integrated trailer is parked, the chassis frame assembly 3 retracts the guide wheel 302 and releases the four supporting legs 303 as supports.

[0028] The adjustable photovoltaic assembly 4 is fixed to the chassis frame assembly 3 by bolt connection, and the photovoltaic bracket 402 is adjusted in angle by the hand-cranked photovoltaic rotating support 403. According to actual lighting conditions, a rotation angle of 0{circumflex over ()}90 with a horizontal plane is adjusted to maximize the utilization of photovoltaic energy; meanwhile, the photovoltaic panels 401 can be expanded left and right through the photovoltaic bracket 402 by utilizing the internal guide rail characteristics of the bracket, so as to receive more light energy.

[0029] The power supply system 5 is installed in the electrical box 501. The energy received by the photovoltaic panels is converted into maximum energy through the MPPT controller and input into batteries for energy storage. Then battery energy is connected to the DC/DC voltage stabilizing controller and safely and reliably output to loads of the monitoring and lighting assembly for monitoring and lighting use. Meanwhile, the batteries are connected to a set of the DC/AC controller and a set of AC/DC controller. In the absence of light, the AC/DC controller can be used to convert mains power supply into battery energy storage. The batteries can also convert energy into the same power supply as the mains power supply through the DC/AC controller, which can be regarded as an outdoor mobile power supply for users to use other loads. The power supply system 5 comprises two switches, namely the photovoltaic access switch S1 and the monitoring and lighting load access switch S2, which are introduced to external control panels, so that the user can use and shut down the power supply system by controlling the switches, and the control is safe and simple.

[0030] The hand-cranked photovoltaic mobile integrated trailer according to the present invention has a simple and reliable adjustment mechanism with high cost performance. Angles of the photovoltaic panels can be adjusted according to the light and the rotation angle adjustment of 0{circumflex over ()}90 with the horizontal plane can be achieved to maximize the utilization of light energy and meet multi-directional monitoring and lighting requirements. Meanwhile, a topological structure of the power supply system is proposed, which not only has the ability to supply power safely and efficiently, but also has the function of serving as an emergency power supply.

[0031] The above are only embodiments of the present invention and are not intended to limit the present invention, which is subject to various changes and variations for those skilled in the art. Any modification, replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
