Furthermore, the insufficient shock resistance of existing refrigeration equipment fails to effectively address the instability in refrigeration caused by vehicle vibrations, and in some cases, may even lead to a complete failure to refrigerate.

Detailed Implementation

[0033] The specific implementation of a special refrigeration device that integrates wind and solar energy storage and oil and gas power generation provided by this utility model will be further described in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1-3 As shown, a special refrigeration device integrating wind and solar energy storage and oil and gas power generation is used in conjunction with an external wind turbine and solar photovoltaic panels to achieve the conversion of wind and solar energy into electricity.

[0035] Preferably, the cooling chamber is provided with an inner liner, which includes a top plate, a bottom plate 9, two side plates 8, and a ventilator.

A foam layer (not shown in the figure) is provided between the two side plates 8 and the air duct assembly 4 and the second outer shell 2.

[0036] Preferably, in order to facilitate the installation of shelves in the refrigeration room, the two side plates 8 are provided with a number of support members 801 at equal intervals from top to bottom.

[0037] like Figure 7 As shown, the air duct assembly 4 includes an upper air duct plate 6 and a lower air duct plate 7; the back air plate is provided with several air inlets at equal intervals; the bottom plate 9 is provided with a return air inlet; the upper air duct plate 6 is provided with several air outlets 601 corresponding to the positions of the air inlets; the air inlets and return air inlets are both connected to the air duct structure, thereby realizing the circulation of cold air in the refrigeration room.

[0038] In order to better deliver cold air from the air duct structure to the cooling chamber, a fan 701 is also provided on the side of the lower air duct plate 7 near the upper air duct plate 6.

[0039] like Figure 4 As shown, a structural clearance 10 is provided at the lower part of the ventilator of the inner liner, and the space between the structural clearance 10 and the second outer shell 2 forms a compressor chamber, and a refrigeration system 5 is provided in the compressor chamber.

[0040] It is worth noting that, in order to extend the low temperature maintenance time as much as possible in the event of a power outage, the inner wall of the second outer shell 2 is covered with a vacuum insulation layer (not shown in the figure), and the inner liner is made of phase change material.

[0041] like Figure 6 As shown, the refrigeration system 5 includes a compressor 501, a spiral refrigeration pipeline 502, and an evaporator (not shown in the figure). The evaporator is located within the air duct structure and close to the compressor chamber. The compressor 501 is connected to the evaporator via the spiral refrigeration pipeline 502.

[0042] Preferably, the shock-absorbing assembly includes a fixing bolt, a shock-absorbing spring 503, and a rubber pad 504; a connecting plate 505 is provided at the bottom of the compressor 501, and the connecting plate 505 is provided with bolt holes; the bolt holes on the connecting plate of the compressor 501 are fixed to the bottom plate of the second housing 2 by fixing bolts.

The shock-absorbing assembly can effectively reduce the vibration of the refrigeration system.

[0043] In order to accurately monitor the temperature inside the cooling chamber, the inner wall of the inner liner is equipped with a temperature sensor (not shown in the figure) and several LED lights for illumination (not shown in the figure).

[0044] like Figure 5 As shown, the control system 3 includes an energy management controller 306, a temperature controller (not shown in the figure), a battery 301, a gas generator 302, a rectifier 303, an MPPT controller 304, and a hybrid inverter 305. Preferably, the battery 301 is a lithium iron phosphate battery or a lead-acid battery.

[0045] It is worth noting that the compressor 501, evaporator, fan 701, thermostat, temperature sensor, battery 301, oil-gas generator 302, rectifier 303, MPPT controller 304, hybrid inverter 305, and LED lights in this utility model are all controlled by the energy management controller 306.

[0046] More preferably, the shock-absorbing mounting bracket includes an upper mounting plate 307 and a lower mounting plate 308, and a plurality of shock-absorbing support members 309 are provided between the upper mounting plate 307 and the lower mounting plate 308, which can effectively dampen the control system 3 and avoid affecting the stability of refrigeration.

[0047] More preferably, the second housing 2 is provided with an external device power supply connection port (not shown in the figure) and an external power charging port (not shown in the figure); the external device power supply connection port and the external power charging port are both electrically connected to the battery 301, thereby realizing the charging of the battery 301 by the external power source or the power supply of the device to the external power grid or electrical equipment.

[0048] like Figure 8 As shown, this utility model can select the following four different power supply and energy storage modes according to the actual application environment:

[0049] Mode 1. When using wind power generation mode, an external wind turbine is used in conjunction with an oil-gas generator in the control system. After conversion by a rectifier and a hybrid inverter, the generated electricity is stored in a battery, and then the power supply is completed by the energy management controller.

[0050] Mode 2. When using solar power generation mode, external solar photovoltaic panels are used to collect solar energy, which is then converted by MPPT controller and hybrid inverter to store the generated electricity in batteries. The power supply is then regulated by energy management controller.

[0051] Mode 3. When using the oil and gas power generation mode, the oil and gas generator of the control system is converted by the hybrid inverter to store the generated electricity in the battery, and then the power supply is completed by the energy management controller.

[0052] Mode 4. When using an external power source for direct charging, the battery is directly connected to the external power source charging port for charging, and then the power supply is controlled by the energy management controller.

[0053] like Figure 9 As shown, the specific working principle of this utility model energy storage system is as follows:

[0054] When the battery's stored capacity is below 60%, depending on the actual situation of the current application environment, mode one and mode two (solar or wind power) will be selected first for power conversion until the battery's stored capacity is above 98%. At this point, solar or wind power generation will be stopped, and the battery can then supply its own power or power to other electrical equipment or the external power grid.

[0055] When the battery charge is below 15%, it is directly charged using an external power source (mode four). If no external power source is available, mode three (the built-in oil-gas generator) is used to generate electricity until the battery charge is above 95%, at which point the oil-gas generator stops operating. It is worth noting that in the event of a power outage, where mode three (the oil-gas generator) also fails to generate electricity, this invention can utilize the vacuum insulation layer on the second outer shell surface in conjunction with an inner liner made of heat-absorbing phase change material to extend the refrigeration time as much as possible.

[0056] This utility model combines multiple energy storage modes such as wind power, solar power, and oil and gas generators, and is especially suitable for refrigeration applications in harsh environments or areas with weak power grids, such as war zones and islands.

These terms are merely used to facilitate the description of the structural relationships of the various components or elements of this utility model and do not specifically refer to any part or element of this utility model; they should not be construed as limiting this utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be determined according to the specific circumstances, and they should not be construed as limiting this utility model.
