Description

Technical Field

[0001] The utility model relates to the technical field of energy storage systems, and in particular to a photovoltaic storage and charging mobile cabin power supply. Background Art

[0002] Shelter power supply refers to emergency power supply devices designed for outdoor and emergency scenarios. It usually integrates the relevant equipment required in the power supply process, such as generators, inverters, distribution cabinets, etc., and sets them in a shelter for easy storage, transfer and transportation. After arriving at the area where power supply needs to be guaranteed, the shelter is unfolded and assembled to ensure power supply.

[0003] For example, Chinese patent CN202211209753.4 discloses a vehicle-mounted lightweight mobile power cabin, including a cabin and an energy storage battery system adapted therein, wherein the cabin also includes a cabin base for detachably mounting on a vehicle and a cabin cover mounted on the cabin base. The cabin cover includes a cabin cover upper shell, a cabin cover left shell, a cabin cover right shell, and a cabin cover rear shell that are detachably and waterproofly connected to each other. The cabin base is L-shaped, the bottom edge of the L-shaped is detachably mounted on the vehicle, the longitudinal edge is opposite to the rear shell of the cover, and the outer surface of the longitudinal edge is provided with the human-machine exchange panel. The internal structure of the cabin adopts a modular, drawer-type design to reduce the size of the cabin and reduce the weight of the cabin. The cabin adopts a cabin cover design that is seamlessly installed on the cabin base. After the cabin cover is opened, modular, drawer-type units such as energy storage battery packs and energy storage converter modules can be inspected on all sides of the cabin for easy installation and maintenance.

[0004] For another example, Chinese patent CN201420563255.4 discloses a power supply cabin. The power supply cabin includes a compartment and a generator set. The compartment is provided with an operation room, a generator set room, a silencing room and a winch room. The operation room is equipped with a control panel, a quick connection box, a fuel water jacket heater, a portable generator and a tool box; the generator set room is equipped with a fuel tank and a lighting lamp; the silencing room is equipped with a noise reduction and silencing device; the winch room is equipped with a cable winch; a variety of doors and shutters are installed on both sides and the rear of the compartment; a lifting lighting device is installed on the top of the compartment; and a pulling arm device is installed at the front of the compartment. This is a device with a high degree of integration, a reasonable appearance and volume, a compact structure, complete functions, fast on-site operation, safety and reliability, low investment and fast results. It can meet the power demand of various equipment for field operations of the troops, and can also efficiently provide strong power supply guarantee for power repair, communication maintenance, emergency rescue and other fields.

[0005] However, in the actual implementation process, the inventors found that when this type of technical solution is applied to the photoelectric energy storage system, since the charging efficiency of the photoelectric energy storage system is positively correlated with the area of ​​the photovoltaic panel, the photovoltaic panels in the existing photoelectric energy storage cabins, such as CN202011057956.7, CN202320071803.0, etc., are usually arranged on the outer shell, with a relatively small area and a low charging rate; if an unfolded photovoltaic panel is introduced, such as CN202080016812.9, there will be a problem of relatively large volume.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0039] The utility model includes:

[0040] A photovoltaic storage and charging mobile cabin power supply, such as Figure 1 and Figure 2 As shown, it includes a cabin body 1, which is in the shape of a long cube, and a photovoltaic power generation component 8 is stored in the first functional area of ​​the cabin body 1;

[0041] The shelter body 1 is provided with a first functional area door 1A at a position corresponding to the first functional area. The first functional area door 1A is opened to the outside, and the photovoltaic power generation assembly 8 passes through the first functional area door 1A to reach the outside of the shelter body 1 and is deployed;

[0042] An energy storage device 6 is provided in the second functional area of ​​the shelter body 1, and a photovoltaic storage inverter 3 and a power distribution cabinet 4 are provided in the third functional area of ​​the shelter body 1;

[0043] The photovoltaic storage inverter 3 is electrically connected to the energy storage device 6, the photovoltaic power generation assembly 8 and the power distribution cabinet 4 respectively;

[0044] The third functional area is provided with an energy management unit 2, a photovoltaic storage inverter 3 and a power distribution cabinet 4 from top to bottom;

[0045] The energy management unit 2 is signal-connected to the photovoltaic inverter 3 and the energy storage device 6 respectively.

[0046] Specifically, in order to address the problems of low charging efficiency or inconvenient deployment of the photovoltaic energy storage cabin in the prior art, the internal layout of the cabin is improved in this embodiment, and a first functional area, a second functional area, and a third functional area arranged back to back are provided.

[0047] Specifically, in this embodiment, the cabin body 1 itself is in the shape of a long cube, and its front and back are respectively provided with hatches that open outwards. Among them, the first functional area is located on the side close to the back of the cabin, and the photovoltaic power generation assembly 8 in a folded state is stored in the first functional area. The photovoltaic power generation assembly 8 is a semi-flexible assembly that can be deployed. When deployment is required, the hatch located in the first functional area is opened, and the photovoltaic power generation assembly 8 can be pulled out from the first functional area and deployed to meet the power generation needs.

[0048] Correspondingly, a second functional area and a third functional area are set on the side of the cabin body 1 close to the front, wherein the second functional area is mainly used to store the energy storage device 6, which is mainly composed of a battery management system and a plurality of battery modules, and can store the electric energy generated by the photovoltaic power generation assembly 8.

[0049] The third functional area is mainly used to set up the energy management unit 2, the photovoltaic storage inverter 3 and the distribution cabinet 4. Among them, the photovoltaic storage inverter 3 is connected to the energy storage device 6, the photovoltaic power generation component 8 and the distribution cabinet 4 respectively, and the energy management unit 2 is used to manage the flow of electric energy so that the cabin power supply itself can achieve corresponding charging and discharging control.

[0050] For example, in the photovoltaic energy storage state, the photovoltaic power generation assembly 8 generates electric energy, and the energy management unit 2 controls the direct current to be directly input into the energy storage device 6 via the photovoltaic storage inverter 3 to charge the energy storage device 6;

[0051] When there is an external load, it can be divided into two situations: DC output and AC output according to the different load types. In order to achieve a better power supply effect, the power distribution cabinet 4 is provided with an AC output port and a DC output port, which are connected to electrical equipment of different power supply types respectively;

[0052] When there are DC power-consuming devices, the DC power output by the photovoltaic power generation assembly 8 is split through the photovoltaic storage inverter 3, a part of which is input into the energy storage device 6 to charge the energy storage device 6, and the other part is supplied to the DC power-consuming devices through the power distribution cabinet 4;

[0053] When there are AC power equipment, the DC power output by the photovoltaic power generation assembly 8 is split through the photovoltaic storage inverter 3, a part of which is input to the energy storage device 6 to charge the energy storage device 6, and the other part is inverted by the photovoltaic storage inverter 3 to form AC power, and then the AC power equipment is powered by the power distribution cabinet 4;

[0054] Also, when the photovoltaic power generation component 8 is not deployed or the power generation power is insufficient, the energy storage device 6 switches from the charging state to the discharging state, and the energy storage device 6 outputs direct current, which is inverted by the photovoltaic storage inverter 3 to form alternating current, and then supplied to the AC power equipment through the distribution cabinet 4.

[0055] The above control process is mainly realized by switching the corresponding relay circuit by the energy management unit 2. It is a control process that is easy to realize for those skilled in the art and will not be elaborated here.

[0056] During the implementation process, the energy management unit 2 is mainly used to manage the energy storage device 6, the photovoltaic storage inverter 3 and other devices. It is mainly implemented by a programmable logic controller or other equivalent embedded devices. In order to realize the corresponding control process, it often adopts a bus system, such as a CAN bus to connect various modules.

[0057] In one embodiment, Figure 3 As shown, the photovoltaic power generation assembly 8 includes a plurality of panel units 8A that are hingedly connected in sequence, and a pair of hinged rotating shafts are respectively provided on both sides along the unfolding direction between adjacent panel units 8A;

[0058] The panel unit 8A is connected via a hinged shaft;

[0059] The hinged shaft includes a bracket shaft, and a pair of telescopic brackets 8B are provided at both ends of the bracket shaft along the length direction of the shaft;

[0060] When the photovoltaic power generation assembly 8 is unfolded, the telescopic bracket 8B extends downward to support the panel unit 8A.

[0061] Specifically, in order to achieve a better storage effect, in this embodiment, a hinged shaft connection is adopted for multiple panel units 8A. At the same time, in order to prevent the panel unit 8A from sinking, a bracket shaft is arranged at intervals in the hinged shaft, and telescopic brackets 8B are arranged at both ends of the bracket shaft, and the telescopic brackets 8B are connected to the bracket shaft through a ball head. When the panel unit 8A is folded, the telescopic bracket 8B is rotated to the same direction as the folded panel unit 8A through the ball head to store it in the first functional area; when the panel unit 8A is unfolded, the telescopic bracket 8B is rotated to a direction perpendicular to the panel unit 8A through the ball head to support the panel unit 8A. The telescopic bracket 8B itself is a multi-section structure, which can be extended and retracted to change the height.

[0062] When the photovoltaic power generation assembly 8 is folded, the adjacent panel units 8A are folded in sequence through the hinge shaft, so that all the panel units 8A are finally stored in the vertical direction and placed in the first functional area;

[0063] When the photovoltaic power generation assembly 8 is unfolded, the first functional area hatch 1A is opened, and then the panel unit 8A is pulled out along the long axis direction so that the multiple panel units 8A are turned to the horizontal direction; then, the telescopic bracket 8B is unfolded to support the panel unit 8A.

The fire-fighting device 5 itself is a prior art, which can be an active fire-fighting device triggered by a signal. For example, the battery management unit generates a corresponding signal according to the battery temperature to trigger the fire-fighting device 5, or smoke, temperature and other sensors are configured in the fire-fighting device 5, which can be automatically started according to the environmental conditions. In one embodiment, the fire-fighting device 5 includes a smoke sensor, a fire extinguisher body and a fire alarm controller.
