[0020] Please refer to Figs. 1 to 2 , the utility model provides a kind of integrated outdoor multi-energy collaborative power station 100, including box 1 and the mobile assembly installed at the bottom of box 1, box 1 includes bottom plate 11 and several side plates 12.

[0021] Specifically, bottom plate 11 and side plate 12 are surrounded to form a first containing cavity 13, and the first containing cavity 13 contains an electric control assembly 2, a generator module 3 electrically connected to the electric control assembly 2, a solar module 4, a battery module 5 and a PLC control unit.

[0022] Among them, the electric control assembly 2 includes a converter 21 and a logic executor 22 connected by a cable, and the logic executor 22 is installed on the side plate 12.

[0023] Further, the side plate 12 is provided with a power grid access port 6, and the power grid access port 6 is connected with the electric control assembly 2; the program of the PLC control unit is set to prioritize solar energy, power supply / battery, and generator, and the logic executor 22 is controlled to realize seamless switching of multiple power sources.

[0024] As shown in Figs. 1-2 , the first containing cavity 13 is provided with a mounting bracket 14, and the mounting bracket 14 is vertically installed on the bottom plate 11 and used for clamping and fixing the battery module 5 on the bottom plate 11.

[0025] Please continue to refer to Fig. 2 , the converter 21 is installed on the top of the mounting bracket 14.

[0026] Specifically, the converter 21 is a bidirectional converter 21, the converter 21 includes an AC end and a DC end, and the converter 21 is used for supporting bidirectional conversion of direct current and alternating current and voltage-stabilized output. The converter 21 is arranged to realize AC-DC power conversion in the circuit, and can convert a high-voltage power supply into a stable low-voltage power supply required by the device through a step-down or step-up function.

[0027] Please continue to refer to Fig. 2 The generator module 3 is installed on the bottom plate 11.

[0028] Specifically, the generator module 3 includes a fuel generator 31 and an oil tank 32 arranged above the fuel generator 31. The oil tank 32 is used to contain fuel to provide fuel for the operation of the generator.

[0029] The fuel generator 31 is connected to the AC end of the converter 21 through the logic executor 22. The electrical energy released by the generator module 3 can be stored in the battery module 5 after passing through the converter 21, or can be directly outputted outward.

[0030] It should be noted that the generator module 3 is not economical and not environmentally friendly, and therefore is the lowest priority power supply mode of the device. However, as a power supply mode in emergency situations, it is essential.

[0031] Please continue to refer to Fig. 2 The battery module 5 is arranged opposite to the generator module 3, and the battery module 5 is connected to the DC end of the converter 21 through a cable. The battery module 5 can be used to store the electrical energy released by the mains, the solar module 4 and the generator module 3, and output the electrical energy when other power supply modes cannot work outdoors, and the voltage of the electrical energy outputted by the battery is stable.

[0039] In addition, the box body 1 is further provided with a dustproof cover plate.

[0040] The implementation principle of the outdoor integrated multi-energy coordinated power station 100 in the utility model is that when a technician needs to use electricity outdoors, the power utilization device is connected to the external power supply socket 7. The PLC control unit preferentially uses the solar module 4 for power supply, and then uses the commercial power, and if there is no commercial power, the battery module 5 is used for power supply; when the power supply of the battery module 5 is completed or in an emergency, the generator module 3 is used for power supply. In addition, when the device is not used, the solar module 4 and the commercial power can be used to charge the battery module 5, so as to be used in an outdoor power failure scene.
