DETAILED DESCRIPTION

[0041] Specific implementation method 1. Combination Figures 1 to 6 To explain this embodiment, the portable power generation system of this embodiment includes a turbine generator set 2, a liquid storage tank 3, a dynamic cold storage condenser 4, a working fluid pump 5, a warm seawater pump 6, an evaporator 7 and a cold seawater pump 10;

[0042] The warm seawater inlet of the warm seawater pump 6 is connected to the outside of the aircraft body 1; the warm seawater outlet of the warm seawater pump 6 is connected to the warm seawater inlet of the evaporator 7; the warm seawater outlet of the evaporator 7 is arranged outside the aircraft body 1;

[0043] The exhaust steam working medium inlet of the evaporator 7 is connected to the exhaust steam working medium outlet of the working medium pump 5; the exhaust steam working medium outlet of the evaporator 7 is connected to the exhaust steam working medium inlet of the turbine generator set 2; the exhaust steam working medium outlet of the turbine generator set 2 is connected to the exhaust steam working medium inlet 4-3 of the power-type cold storage condenser 4; the exhaust steam working medium outlet 4-4 of the power-type cold storage condenser 4 is connected to the exhaust steam working medium inlet of the working medium pump 5 through the liquid storage tank 3; the turbine generator set 2 drives the generator to generate electricity;

[0044] The cold seawater inlet of the cold seawater pump 10 is connected to the outside of the aircraft body 1; the cold seawater outlet of the cold seawater pump 10 is connected to the cold seawater inlet 4-9 of the powered cold storage condenser 4; the cold seawater outlet 4-10 of the powered cold storage condenser 4 is arranged outside the aircraft body 1.

[0045] In this embodiment, the evaporator 7 is a plate or shell and tube heat exchanger, which is used to pump warm seawater into the evaporator 7 through the warm seawater pump 6 to provide a heat source for the exhaust steam working fluid when the aircraft body 1 floats to the sea surface; the exhaust steam working fluid adopts an organic Rankine cycle working fluid, which evaporates in the warm water state on the sea surface within the ocean temperature range and condenses in the cold seawater state on the seabed; the turbine generator set 2 is a centripetal turbine set, which converts the kinetic energy of the exhaust steam working fluid into mechanical energy after it is converted into steam; the mechanical energy drives the generator to generate electricity.

[0046] The working principle of the thermoelectric power generation described in this embodiment is:

[0047] The power-type cold storage condenser 4 is a four-working medium, dual-function cold storage condenser; the four working mediums inside it are phase change cold storage material, exhaust steam working medium, cold seawater and power oil. In the cold storage condensation function, the cold seawater is pumped in by the cold seawater pump 10, flows through the phase change cold storage material to make it undergo a liquid-solid phase change, and stores cold energy; when the aircraft body 1 is located in the warm water working condition on the sea surface, the cold energy stored in the phase change cold storage material provides a cold source for the Rankine cycle, that is, the steam working medium evaporates through heat exchange with warm seawater in the evaporator 7, enters the turbine generator set 2 to generate electricity, and the exhaust steam working medium flowing out of the turbine generator set 2 flows through the power-type cold storage condenser 4 and is condensed and stored in the liquid storage tank 3, wherein the top of the liquid storage tank 3 is provided with an exhaust steam working medium inlet, and the bottom of the liquid storage tank 3 is provided with an exhaust steam working medium outlet.

[0048] Specific embodiment 2: This embodiment further defines the onboard power generation system of an energy storage underwater vehicle described in specific embodiment 1. In this embodiment, the onboard power generation system further includes a power oil tank 14, an inner oil tank 15, an outer oil bag 16 and a piston group 17;

[0049] The power type cold storage condenser 4 is also provided with a power oil bag interface 4-6; the power oil bag interface 4-6 is connected to the oil storage space of the power oil tank 14;

[0050] The oil storage space of the inner oil tank 15 is connected to the oil storage space of the outer oil bag 16;

[0051] The piston group 17 is disposed between the inner oil tank 15 and the power oil tank 14 ; and when the piston group 17 moves, the oil storage space of the inner oil tank 15 and the oil storage space of the power oil tank 14 change synchronously.

[0052] In this embodiment, by adding a power oil tank 14, an inner oil tank 15, an outer oil bag 16 and a piston group 17, and by the power type cold storage condenser 4 also provided with a power oil bag interface 4-6; the power function of the body-mounted power generation system is increased;

[0053] In the power function, since the exhaust steam releases heat through the cold storage condenser when the Rankine cycle is working, the phase change energy storage material absorbs the heat of the working fluid and undergoes a solid-liquid phase change and expands in volume. The volume expansion of the phase change energy storage material squeezes the power oil, causing the power oil to flow into the power oil tank 14, causing the entire piston group 17 to move to the left. Under the action of the pressure difference, the power oil in the outer oil bag 16 flows into the inner oil tank 15, thereby reducing the volume of the entire body-mounted power generation system while keeping the total mass unchanged, turning it into negative buoyancy, and realizing the autonomous diving of the aircraft body 1.

[0054] When the vehicle body 1 reaches the seabed, cold seawater is pumped into the powered cold storage condenser 4 by the cold seawater pump 10, causing the phase change cold storage material to condense. This process enables the phase change cold storage material to store cold energy, while at the same time, the volume of the phase change cold storage material shrinks. Since the phase change cold storage material shrinks when it is cold, the power oil in the power oil tank 14 is pressed into the powered cold storage condenser 4, causing the piston to move right. The rightward movement of the piston discharges the power oil in the inner oil tank 15 into the outer oil bag 16, causing the volume of the body-mounted power generation system to expand while the total mass remains unchanged, thereby achieving autonomous buoyancy.

[0055] Specific embodiment three. This embodiment further limits the energy storage type underwater vehicle body-mounted power generation system described in specific embodiment two. In this embodiment, the turbine generator set 2, liquid storage tank 3, power-type cold storage condenser 4, working fluid pump 5, warm seawater pump 6, evaporator 7, cold seawater pump 10, power oil tank 14, internal oil tank 15 and piston group 17 are all arranged inside the vehicle body 1; the external oil bag 16 is arranged outside the vehicle body 1.

[0056] In this embodiment, the power function of the body-mounted power generation system is ensured through the above arrangement.

[0061] The power oil bag 4-5 is filled with power oil, and the power oil bag 4-5 is provided with an oil inlet and outlet interface, and the oil inlet and outlet interface is the power oil bag interface 4-6.

[0062] In this embodiment, the power-type cold storage condenser 4 embodies the advantages of a four-working medium, dual-function cold storage condenser. The four working mediums inside are phase-change cold storage material 4-7, steam working medium, cold seawater and power oil; the cooperation between steam working medium and cold seawater realizes the basic function of body-mounted power generation; at the same time, the increase of phase-change cold storage material 4-7 and power oil enables the power-type cold storage condenser 4 to cooperate with the aircraft body 1 to float or dive; on the basis of temperature difference power generation, the energy consumption of the aircraft body 1 is further saved.

[0063] Specific implementation method 5: This implementation method further limits the energy storage type underwater vehicle body-mounted power generation system described in specific implementation method 4. In this implementation method, the phase change cold storage material 4-7 is n-tetradecane.

[0064] In this embodiment, the characteristic of n-tetradecane absorbing or releasing heat during the solid-liquid phase transition process makes it an effective thermal energy storage and temperature regulation material suitable for the body-attached power generation system.

[0068] In this embodiment, by adding a cold seawater inlet pipe 11 and a cold seawater outlet pipe 12, the airtightness of the aircraft body 1 can be ensured, and the uncontrolled backflow of cold seawater into the aircraft body 1 can be effectively prevented; at the same time, the other end of the cold seawater inlet pipe 11 passes through the bottom of the aircraft body 1, and the temperature of the seawater gradually decreases from top to bottom, thereby ensuring the maximization of the cold storage of the powered cold storage condenser 4.

[0069] Specific embodiment 7, this embodiment further limits the energy storage type underwater vehicle body power generation system described in specific embodiment 2. In this embodiment, the piston group 17 includes a first piston plate, a second piston plate and a connecting rod;
