[0049] The skid-mounted structure 300 is disposed in the container 200 and on the trailer chassis 100, and is provided with:

[0050] A first battery pack 301, an electric motor 302, an inertial energy storage wheel 303, a water storage tank 304, an electrolysis device 305, a condenser 306, a first compressor 307, a second compressor 308, a hydrogen internal combustion engine 309, a first generator 3010, a second generator 3011, a plurality of transmission devices 3012, a transformer 3013, a distribution box 3014, a first gas cylinder 3015 and a second gas cylinder 3016, wherein:

[0051] The first battery group 301 is electrically connected to the solar panel 202, the motor 302, the first compressor 307 and the second compressor 308 respectively. The solar panel 202 is used to transmit electric energy to the first battery group 301, and the first battery group 301 is used to transmit electric energy to the motor 302, the first compressor 307 and the second compressor 308 respectively.

[0052] The water storage tank 304 is used to store purified water and deliver purified water to the electrolysis device 305;

[0053] The motor 302 drives the inertia energy storage wheel 303 to rotate through a transmission device 3012, and the inertia energy storage wheel 303 drives the first generator 3010 to generate electricity through another transmission device 3012. The inertia energy storage wheel 303 is used to transmit kinetic energy to the first generator 3010;

[0054] The first generator 3010 is used to transmit electric energy to the electrolysis device 305, and the electrolysis device 305 is used to electrolyze pure water and produce hydrogen and oxygen;

[0055] The first compressor 307 is used to store hydrogen into the first gas cylinder 3015, and the second compressor 308 is used to store oxygen into the second gas cylinder 3016;

[0056] The hydrogen internal combustion engine 309 uses the hydrogen in the first gas cylinder 3015 and the oxygen in the second gas cylinder 3016 as fuel to work, and drives the second generator 3011 to transmit electric energy through another transmission device 3012. The condenser 306 is used to condense the pure water produced by the hydrogen internal combustion engine 309 and introduce it into the water storage tank 304;

[0057] The transformer 3013 is electrically connected to the first battery pack 301 , the first generator 3010 , the second generator 3011 and the distribution box 3014 respectively. The first battery pack 301 , the first generator 3010 and the second generator 3011 transmit electric energy to the transformer 3013 respectively. The distribution box 3014 is used to distribute the electric energy of the transformer 3013 .

[0058] In the embodiment of the present invention, the relevant staff park the multifunctional towable new energy hybrid energy storage station at a predetermined position by towing the vehicle, and set various working parameters of the multifunctional towable new energy hybrid energy storage station through the control console of the towing vehicle, such as setting the working time and specific working time of the solar panel 202, and other specific parameters;

[0059] The relevant staff will connect the electrical equipment to the distribution box 3014 and wait for the multifunctional towable new energy hybrid energy storage station to supply power.

[0060] Specifically, suppose that the multifunctional drag-type new energy hybrid energy storage station starts working, and the solar panel 202 works for 6 hours a day, and the output power is P1=5 kW , the efficiency of the first battery group η1=0.9, then the energy output of the solar panel 202 is E1=P1·t1=6 h 5 kW =30 kWh , then the energy that can be stored in the first battery pack 301 is E2=E1·η1=30 kWh0.9 = 27 kWh ;

[0061] Assuming that the efficiency η2 of the motor 302 is 0.85, the efficiency η3 of the inertia energy storage wheel 303 is 0.9, and the efficiency η4 of the first generator 3010 is 0.9, the energy output of the system composed of the motor 302, the inertia energy storage wheel 303 and the first generator 3010 is E3=E2·η2·η3·η4=27 kWh 0.85 0.9 0.9 = 18.38 kWh ;

[0062] The electrolysis device 305 electrolyzes pure water and produces hydrogen and oxygen according to the energy E3 obtained. Where m is the mass of water to be electrolyzed, V is the volume of water to be electrolyzed, and F is the Faraday constant. The mass of water that can be electrolyzed is approximately 5.02 kg ;

[0063] Assume that the power of the first compressor 307 is P2=1 kW , the working time of the first compressor 307 is t2=2 h , the energy required by the first compressor 307 is E4 = P2·t2 = 1 kW 2 h =2 kWh , the power of the second compressor 308 is P3=1 kW , the working time of the second compressor 308 is t3=2 h , the energy required by the second compressor 308 is E5 = P3·t3 = 1 kW 2 h =2 kWh ;

[0064] Assuming that the efficiency of the hydrogen internal combustion engine 309 is η5=0.4 and the efficiency of the second generator 3011 is η6=0.9, the energy output of the system composed of the hydrogen internal combustion engine 309 and the second generator 3011 is E6=E7·η4·η5=(18.28 kWh -2 kWh -2 kWh )·0.4·0.9=5.1768 kWh , where E7 is the total chemical energy of the water being electrolyzed;

[0065] Assuming that the efficiency of transformer 3013 is η6=0.9, and the efficiency of distribution box 3014 is η7=0.95; it can be known that the energy that can be output by the multifunctional drag-type new energy hybrid energy storage station is E (x) =(E2+E6)=27 kWh +5.1768 kWh =32.1768kWh The self-sustaining energy of this multifunctional drag-type new energy hybrid energy storage station is E (y) =E3+E4+E5=2 kWh +2 kWh +5.1768 kWh =9.1768 kWh , then the actual output energy of the multifunctional drag-type new energy hybrid energy storage station is E (z) =[E (x) -E (y) ]·η6·η7=(32.1768 kWh -9.1768 kWh )·0.9·0.95=19.6650 kWh ;

[0066] According to the multifunctional towable new energy hybrid energy storage station disclosed in the present invention, the solar panel 202 is designed to work only for a short period of time every day. On the one hand, it ensures the effective collection of energy, and on the other hand, it effectively protects the solar panel 202 by retracting it into the container 200 during non-use periods, thereby extending its service life. On the other hand, it can output stable electricity every day, ensuring the reliability and continuity of energy supply, and is suitable for a variety of application scenarios.

[0067] To better explain the present invention, in one embodiment of the present invention, when the motor 302 drives the inertia energy storage wheel 303 to rotate through a transmission device 3012 and reaches a preset speed threshold, the first battery pack 301 stops supplying power to the motor 302;

[0068] When the first battery group 301 is fully charged, the upper cover 201 of the container 200 retracts the solar panel 202 into the container 200 .

[0069] Specifically, by setting a preset speed threshold of the inertial energy storage wheel 303, automatic adjustment of the entire device can be achieved, and at the same time, the upper cover 201 of the container 2 () () will automatically retract the solar panel 202 into the container 2 () ().

[0070] In order to better explain the present invention, in one embodiment of the present invention, the multifunctional towable new energy hybrid energy storage station further includes:

[0071] A second battery pack 3017, which is electrically connected to the second generator 3011, and the second generator 3011 is used to transmit electrical energy to the second battery pack 3017;

[0072] When the power distribution box 3014 does not transmit power to the external power-consuming equipment and the second battery pack 3017 is half full, the hydrogen internal combustion engine 309 stops driving the second generator 3011 to transmit power;

[0073] The transformer 3013 is electrically connected to the second battery pack 3017 , and the second battery pack 3017 transmits electrical energy to the transformer 3013 .

[0074] Specifically, when the distribution box 3014 does not transmit electric energy to the external electrical equipment and the second battery pack 3017 is half full, the hydrogen internal combustion engine 309 will stop driving the second generator 3011 to transmit electric energy, which can save the consumption of hydrogen and oxygen and further improve the energy efficiency of the system. The transformer 3013 is electrically connected to the second battery pack 3017, and the second battery pack 3017 can transmit electric energy to the transformer 3013, thereby enhancing the endurance of the multifunctional towable new energy hybrid energy storage station.

[0075] In addition, it should be noted that when the first gas cylinder 3015 reaches the first preset capacity threshold or the second gas cylinder 3016 reaches the second preset capacity threshold, the first compressor 307 and the second compressor 308 stop working at the same time.

[0076] Specifically, setting a first preset capacity threshold for the first gas cylinder 3015 and setting a second preset capacity threshold for the second gas cylinder 3016 can prevent over-pressurization of the gas cylinders, ensure safe operation of the system, and further reduce unnecessary energy waste, thereby improving the reliability and stability of the system.

[0077] In addition, it should be noted that the inertial energy storage wheel 303 is located in the middle position of the trailer chassis 100 .

[0078] Specifically, the layout of the inertia energy storage wheel 303 in the middle of the trailer chassis 100 not only helps to balance the weight distribution of the entire vehicle, but also ensures that the inertia energy storage wheel 303 is more stable during operation and reduces the impact of vibration on other components, thereby improving the performance and service life of the entire system.

[0079] In summary, according to the multifunctional towable new energy hybrid energy storage station disclosed in the present invention, the solar panel 202 is designed to work only for a short period of time every day. On the one hand, it ensures the effective collection of energy, and on the other hand, it effectively protects the solar panel 202 by retracting it into the container 200 during non-use periods, thereby extending its service life. On the other hand, it can output stable electricity every day, ensuring the reliability and continuity of energy supply, and is suitable for a variety of application scenarios.
