[0052] Please also refer to Figure 1 and Figure 2In the first aspect, an embodiment of the present application provides a lifeboat energy compensation system, comprising a power generation device 11, a heat collection device 12, a heating device 13 and a control device 14. The power generation device 11 comprises a multi-stage power generation module, which uses working fluids with different boiling points to generate electricity. The working fluid of the upper-stage power generation module 111 is used to heat the working fluid of the lower-stage power generation module 111 after driving power generation. The heat collection device 12 is used to absorb solar energy and heat the working fluid. The heating device 13 comprises a waste heat heating module. The waste heat heating module pipeline is connected to the power generation device 11. The waste heat heating module uses the high-temperature working fluid of the power generation module and the waste heat after the working fluid generates electricity for heating. The control device 14 is communicatively connected to the power generation device 11 and the waste heat heating module.

[0053] The lifeboat energy compensation system of the embodiment of the present application is provided with a heat collecting device 12 to absorb solar energy and use it as a heat source to heat the working fluid, thereby causing the working fluid to evaporate and generate electricity for the power generation module, thereby achieving the rational use of marine resources, using solar energy to provide additional energy compensation for the lifeboat, and timely replenishing the energy for the lifeboat, so that the lifeboat has sufficient energy reserves and improves the safety of the lifeboat. At the same time, the multi-stage power generation modules of the power generation device 11 use working fluids with different boiling points to generate electricity. The working fluid of the upper-stage power generation module 111 is used to heat the working fluid of the lower-stage power generation module 111 after driving the power generation, so as to facilitate the use of the working fluid's waste heat, improve the power generation efficiency, and thus improve the energy utilization rate. In addition, by providing a waste heat heating module, the high-temperature working fluid and the waste heat of the working fluid of the power generation module are used to heat the people on the lifeboat, which can efficiently and rationally utilize thermal energy and further improve the energy utilization rate.

[0054] Please combine Figures 2 to 5 In some embodiments, the power generation device 11 includes a primary power generation module 111 and at least one secondary power generation module arranged in sequence. The heat collection device 12 is used to heat the primary working fluid of the primary power generation module 111. The primary working fluid is used to drive the primary power generation module 111 to generate electricity and form a primary waste heat working fluid after being heated and evaporated. The primary waste heat working fluid is used to heat the working fluid of all secondary power generation modules.

[0055] In this way, each level of power generation module is a temperature difference power generation unit, which can componently utilize energy and reduce energy loss. In addition, the waste heat of the working fluid of the first-level power generation module 111 can be used to heat the working fluid of the subsequent power generation modules at each level, thereby increasing the utilization methods of waste heat working fluid, efficiently utilizing thermal energy, and further improving energy utilization.

[0056] Exemplarily, the secondary power generation module includes a secondary power generation module 112 and a tertiary power generation module 113. The primary waste heat working fluid is used to heat the working fluid of the secondary power generation module 112 and the tertiary power generation module 113. The secondary power generation module 112 is driven by the secondary working fluid to generate electricity and obtain the secondary waste heat working fluid. The secondary waste heat working fluid is used to heat the tertiary working fluid of the tertiary power generation module 113.

[0057] Optionally, the power generation device 11 also includes a four-stage power generation module 114, and the first-stage waste heat working fluid is also used to heat the working fluid of the four-stage power generation module 114. The third-stage working fluid obtains the third-stage waste heat working fluid after generating electricity through the third-stage power generation module 113, and the third-stage waste heat working fluid is used to heat the fourth-stage working fluid of the four-stage power generation module 114.

[0058] That is, the four-stage power generation module 114 can be heated by the first-stage waste heat working fluid and the third-stage waste heat working fluid, and the first-stage waste heat working fluid can be used to heat the working fluid of the subsequent power generation modules to increase the utilization methods of the waste heat working fluid, efficiently utilize thermal energy, and further improve energy utilization.

[0059] In some embodiments, the primary working fluid is seawater, the secondary working fluid is an ammonia-water mixture, the tertiary working fluid is a lithium bromide aqueous solution, and the quaternary working fluid is tetrafluoroethane. This ensures that the boiling points of the working fluids in each power generation module are different, and the boiling points of the working fluids in the power generation device 11 decrease step by step, allowing the waste heat of the working fluid in the previous stage to be used to heat and evaporate the working fluid in the next stage, thereby evaporating and driving the turbine generator to generate electricity. Furthermore, using seawater as the primary working fluid facilitates working fluid replenishment. Furthermore, the primary power generation module 111 utilizes solar energy and seawater for power generation. Solar energy and seawater are obtained from the natural environment and are easier to replenish than other materials when the lifeboat is operating. This ensures that the primary power generation module 111 has better sustainability, continuously providing power to the lifeboat, meeting the energy compensation requirements of the lifeboat and improving the safety of the lifeboat.

[0060] As an alternative embodiment, the secondary working fluid may be an ethanol-water solution or acetone, the tertiary working fluid may be tetrahydrofuran or ethyl formate, and the quaternary working fluid may be R-1234yf (a hydrofluoroolefin refrigerant with a boiling point of -29°C, close to tetrafluoroethane).

[0061] Please combine Figure 2 and Figure 3In some embodiments, the first-stage power generation module 111 includes a first-stage heat exchange box 1111 and a first-stage turbine generator 1112. The first-stage heat exchange box 1111 is used for heat exchange between the first-stage working fluid and the solar energy. The first-stage heat exchange box 1111 includes a first outlet and a second outlet. The first-stage turbine generator 1112 is connected to the first outlet through a pipeline. The second-stage power generation module 112 includes a first power generation unit 112a and a second power generation unit 112b. The first power generation unit 112a and the second power generation unit 112b include the second-stage heat exchange box 1121 and the second-stage turbine generator 1112. 122. The secondary heat exchange box 1121 pipeline of the first power generation unit 112a is connected to the first-stage turbine generator 1112, and the secondary heat exchange box 1121 pipeline of the second power generation unit 112b is connected to the second outlet. After heat exchange, the primary working fluid obtains a primary gaseous working fluid (i.e., seawater that is heated to become water vapor) and a primary liquid working fluid (i.e., seawater that is heated but not converted into water vapor). The primary gaseous working fluid enters the first-stage turbine generator 1112 through the first outlet to generate electricity, and the primary liquid working fluid enters the second power generation unit 112b through the second outlet to heat the secondary working fluid.

[0062] In this way, the two power generation units of the secondary power generation module 112 respectively use the primary waste heat working medium and the primary liquid working medium, and can respectively utilize the heated seawater in two states to improve the utilization rate of seawater and improve the power generation efficiency.

[0063] In addition, considering that the heat source of the first-level power generation module 111 is solar energy and the first-level working fluid is seawater, both solar energy and seawater are easy to replenish, which can make the first-level working fluid and the first-level waste heat working fluid have greater potential, which is conducive to providing sufficient supply and heat. Based on this, the two power generation units of the second-level power generation module 112 respectively use the first-level waste heat working fluid and the first-level liquid working fluid. The first-level waste heat working fluid can be used to heat the working fluid of the subsequent power generation modules, which can be beneficial to provide sufficient heat source and first-level working fluid for the lifeboat energy compensation system, meet the energy compensation needs of the lifeboat, ensure the power of the lifeboat, and improve the safety of the lifeboat.

[0064] Optionally, considering that the primary working fluid is seawater, the salt in the seawater will cause damage to the pipelines and equipment, and the impurities in the seawater will contaminate the pipelines and easily form scale, affecting the heating efficiency of the seawater. Based on this, a filter tank is provided at the bottom of the primary heat exchange box 1111, and the salt, impurities and other substances in the seawater are filtered through the filter tank to improve the purity of the seawater and improve the power generation efficiency.

[0065] Optionally, the primary power generation module 111 further includes a primary circulation pump 1113, which is connected to the second power generation unit 112b and the primary heat exchange box 1111. The primary circulation pump 1113 is used to pump excess primary liquid working fluid (unused primary liquid working fluid) in the second power generation unit 112b to the primary heat exchange box 1111. This allows the working fluid to circulate within the primary power generation module 111, thereby improving the utilization rate of the working fluid.

[0066] Optionally, the first power generation unit 112a and the second power generation unit 112b also include a first circulation pump 1123, a second circulation pump 1124 and a secondary flow buffer capsule 1125. The first circulation pump 1123 and the second circulation pump 1124 are respectively communicatively connected to the control device 14. The pipeline of the first circulation pump 1123 is connected to the inlet of the secondary flow buffer capsule 1125 and the tertiary power generation module 113. A part of the secondary waste heat working fluid flows to the tertiary power generation module 113, and another part of the secondary waste heat working fluid flows to the first circulation pump 1123. The pipeline of the second circulation pump 1124 is connected to the outlet of the secondary flow buffer capsule 1125 and the secondary heat exchange box 1121.

[0067] In this way, the first circulation pump 1123 is used to collect excess secondary waste heat working fluid (i.e., the portion not used to heat the third working fluid) and pump it to the secondary flow buffer capsule 1125, so that the working fluid can circulate internally within the secondary power generation module 112, thereby improving the utilization rate of the working fluid. The secondary flow buffer capsule 1125 is provided to temporarily store the secondary waste heat working fluid so that the working fluid can be provided when the power generation module needs it. At the same time, the second circulation pump 1124 is used to pump the secondary waste heat working fluid in the secondary flow buffer capsule 1125 back into the secondary heat exchange box 1121, so that the secondary waste heat working fluid can be heated and evaporated again by the heat source and transported to the secondary turbine generator 1122 for power generation, thereby realizing the recycling of the secondary working fluid.

[0068] Optionally, the first power generation unit 112a and the second power generation unit 112b also include a secondary working fluid storage tank 1126. The secondary working fluid storage tank pipeline is connected to the secondary flow buffer capsule 1125 and is communicatively connected to the control device 14. The secondary working fluid storage tank 1126 supplies and replenishes the secondary flow buffer capsule 1125 to meet the power generation working fluid demand in the secondary power generation module 112 and ensure the stable operation of the secondary power generation module 112.

[0069] Optionally, the lifeboat energy compensation system further includes a plurality of detection control valves 15, which are communicatively connected to the control device 14. The plurality of detection control valves 15 can be respectively arranged in the secondary heat exchange box 1121, between the primary heat exchange box 1111 and the secondary heat exchange box 1121 of the second power generation unit 112b, between the primary turbine generator 1112 and the secondary heat exchange box 1121 of the first power generation unit 112a, between the primary circulation pump 1113 and the primary heat exchange box 1111, at the inlet of the first circulation pump 1123, at the inlet of the second circulation pump 1124, at the outlet of the secondary working fluid storage tank 1126, and at the outlet of the secondary flow buffer bladder 1125. This allows the working fluid gas and pressure values ​​at different locations to be detected and controlled within a reasonable range, thereby improving the control flexibility and reliability of the lifeboat energy compensation system.

[0070] For example, when the detection control valve 15 detects that the secondary working fluid in the secondary heat exchange tank 1121 of the second power generation unit 112b is insufficient, the control device 14 drives the secondary working fluid storage tank 1126 to transport the secondary working fluid to the secondary flow buffer bag 1125, and then pumps the secondary working fluid to the secondary heat exchange tank 1121 through the second circulation pump 1124 to complete the replenishment of the working fluid and ensure the sustainability of the cycle.

[0071] It can be understood that the detection control valve 15 can be used to detect pipeline pressure, the remaining amount of working fluid in the working fluid storage tank, the pressure of the heat exchange tank, etc.

[0072] Optionally, the lifeboat energy compensation device also includes a one-way valve 16, which is arranged in the pipeline between the first-stage circulation pump 1113 and the first-stage heat exchange box 1111 and the outlet pipeline of the turbine generator, so as to guide the one-way flow of the working fluid and reduce the damage to the system caused by the reverse flow of the working fluid.

[0073] Optionally, the one-way valve 16 may be a Tesla valve, or the one-way valve 16 may be a switch valve communicatively connected to the control device 14 , for example, any one of a check valve, a ball valve or a stop valve.

[0074] Please combine Figure 2 、 Figure 4 and Figure 5 In some embodiments, the tertiary power generation module 113 and the fourth-level power generation module 114 each include two power generation units, wherein the heat source of one power generation unit is the first-level waste heat working fluid, and the heat source of the other power generation unit is the previous-level waste heat working fluid. Thus, on the one hand, sufficient heat sources can be provided for the tertiary power generation module 113 and the fourth-level power generation module 114 to ensure that the working fluid can be heated and evaporated for power generation, thereby ensuring power generation efficiency; on the other hand, the waste heat of the working fluid can be reasonably utilized to improve energy utilization.

[0075] For example, the three-stage power generation module 113 includes a third power generation unit 113a and a fourth power generation unit 113b. The third power generation unit 113a and the fourth power generation unit 113b include a three-stage heat exchange box 1131 and a three-stage turbine generator 1132. The three-stage heat exchange box 1131 of the third power generation unit 113a is connected to the first-stage turbine generator 1112 and the second-stage heat exchange box 1121 of the first power generation unit 112a by a pipeline. The third power generation unit 113a heats the three-stage working medium through the first-stage waste heat working medium, that is, the third power generation unit 113a heats the three-stage working medium through the waste heat of water vapor output by the first-stage turbine generator 1112 and the waste heat of water vapor not utilized by the second-stage power generation module 112. The tertiary heat exchange box 1131 of the fourth power generation unit 113b is connected to the secondary turbine generator 1122 of the first power generation unit 112a and the second power generation unit 112b by a pipeline. The fourth power generation unit 113b heats the tertiary working fluid through the secondary waste heat working fluid, that is, the fourth power generation unit 113b heats the tertiary working fluid through the secondary waste heat working fluid output by the first power generation unit 112a and the secondary power generation unit. The secondary waste heat working fluid not utilized by the fourth power generation unit 113b is pumped back to the secondary flow buffer bag 1125 of the first power generation unit 112a and the second power generation unit 112b through the first circulation pump 1123. The four-stage power generation module 114 includes a fifth power generation unit 114a and a sixth power generation unit 114b. The fifth power generation unit 114a and the sixth power generation unit 114b include a four-stage heat exchange box 1141 and a four-stage turbine generator 1142. The four-stage heat exchange box 1141 of the fifth power generation unit 114a is connected to the first-stage turbine generator 1112 and the third-stage heat exchange box 1131 of the third power generation unit 113a through a pipeline. The fifth power generation unit 114a heats the four-stage working medium through the first-stage waste heat working medium, that is, the fifth power generation unit 114a heats the four-stage working medium through the waste heat of water vapor output by the first-stage turbine generator 1112 and the waste heat of water vapor not utilized by the three-stage power generation module 113. The fourth-stage heat exchange box 1141 of the sixth power generation unit 114b is connected to the third-stage turbine generator 1132 of the third power generation unit 113a and the fourth power generation unit 113b by a pipeline. The sixth power generation unit 114b heats the fourth-stage working fluid through the third-stage waste heat working fluid, that is, the sixth power generation unit 114b heats the fourth-stage working fluid through the third-stage waste heat working fluid output by the third power generation unit 113a and the fourth-stage power generation unit. The third-stage waste heat working fluid not utilized by the sixth power generation unit 114b is pumped back to the third-stage flow buffer bag 1134 of the third power generation unit 113a and the fourth power generation unit 113b through the third-stage circulation pump. After the fourth-stage working fluid generates electricity, it is pumped to the fourth-stage heat exchange box 1141 through the fourth-stage circulation pump, thereby completing the power generation and working fluid circulation of the power generation device 11.

[0076] Optionally, the third power generation unit 113a and the fourth power generation unit 113b also include a tertiary working fluid storage tank 1133 and a tertiary flow buffer capsule 1134. The tertiary working fluid storage tank pipeline is connected to the tertiary flow buffer capsule 1134 and is communicatively connected to the control device 14. The tertiary working fluid is supplied and replenished to the tertiary flow buffer capsule 1134 through the tertiary working fluid storage tank 1133 to meet the power generation working fluid demand in the tertiary power generation module 113 and ensure the stable operation of the tertiary power generation module 113.

The four-stage flow buffer capsule 1143 is used to supply the four-stage working fluid to the four-stage heat exchange box 1141 under the action of the detection control valve 15 and the four-stage circulation pump to meet the power generation working fluid requirements in the four-stage power generation module 114 and ensure the stable operation of the four-stage power generation module 114.

[0077] Please combine Figure 6 In some embodiments, the secondary heat exchange box 1121, the tertiary heat exchange box 1131, and the quaternary heat exchange box 1141 all include an outer box 1121a and a hollow heating tube 1121b, a heated buffer bag 1121c, and a detection control valve 15 sequentially arranged inside the outer box 1121a. The heat source is passed into the outer box 1121a to heat the working fluid in the hollow heating tube 1121b. The heated buffer bag 1121c is used to buffer the gas whose volume increases after the working fluid is heated, thereby reducing the damage of the gaseous working fluid to the device.

[0078] Please combine Figure 2 and Figure 7 Optionally, the conveying pipeline in the power generation device 11 (including the conveying pipeline and hollow heating tube in each level of power generation module) adopts an insulated pipe 115, and the insulated pipe 115 is penetrated by a hollow portion. The insulated pipe 115 includes an outer layer 1151 and an inner wall layer 1152. The outer layer 1151 and the inner wall layer 1152 are spaced apart to form a vacuum interlayer, and the inner wall layer 1152 is enclosed to form a hollow portion. The surface of the outer layer 1151 and the inner wall layer 1152 is coated with a metal reflective layer, and a material with high reflectivity (such as aluminum, silver, gold and other metals) is used to efficiently reflect light or electromagnetic waves of a specific wavelength to reduce energy loss, reduce heat loss, and effectively isolate oxygen and water vapor, delaying oxidation or corrosion of internal materials. Vacuum gas is passed into the vacuum interlayer and filled with insulation material (such as polyurethane foam, rubber sponge or rock wool, etc.).

[0079] In this way, by combining the vacuum interlayer with the metal reflective layer, heat loss can be further reduced, the power conversion rate can be improved, and the oxidation or corrosion of the pipeline due to oxygen or water vapor can be delayed, thereby extending the service life of the pipeline.

[0080] Please combine Figure 5 and Figure 8 In some embodiments, the lifeboat energy compensation system further comprises an air cooling device 17, the air cooling device 17 comprises an air cooling box 171 and a heat dissipation pipe 172, the air cooling box 171 is along the first direction (see Figure 8 An air catcher 1711 and an air outlet 1712 are respectively provided on two opposite sides of the air cooling box 171 (in the x direction in the figure). The heat dissipation pipe 172 is reciprocatingly arranged in the air cooling box 171 along the first direction and is located between the air catcher 1711 and the air outlet 1712. The inlet of the heat dissipation pipe 172 is connected to the last-stage power generation module (i.e., the fourth power generation module) in the secondary power generation module of the power generation device 11, that is, the inlet of the heat dissipation pipe 172 is connected to the four-stage turbine generator 1142, and the outlet of the heat dissipation pipe 172 is connected to the four-stage heat exchange box 1141. The air cooling device 17 is used to cool the working medium (i.e., the fourth-stage working medium) after generating electricity through the last-stage power generation module.

[0081] In this way, the air cooling device 17 cools the fourth-stage working fluid after power generation, so that the gaseous fourth-stage working fluid is condensed into liquid due to cooling, which is beneficial to increasing the temperature difference between the heat source and the working fluid, so that the heat source heats and evaporates the working fluid to drive power generation, improving the efficiency of working fluid recycling and power generation efficiency. At the same time, using air cooling to cool the fourth-stage working fluid can facilitate the replenishment of cooling working fluid (wind), thereby saving energy and improving power generation efficiency. In addition, the heat dissipation pipe 172 adopts a reciprocating arrangement to reduce the space inside the air cooling box 171, so that the air cooling box 171 forms a narrow tube effect between the air catcher 1711 and the air outlet 1712, so that the air flow rate in the air cooling box 171 is faster, thereby improving the cooling efficiency of the fourth-stage working fluid and improving power generation efficiency. It can also increase the flow path of the fourth-stage working fluid and extend the passage time of the fourth-stage working fluid, which is beneficial to cooling the fourth-stage working fluid and reducing the temperature of the fourth-stage working fluid after passing through the air cooling device 17.

[0082] Optionally, the air catching port 1711 and the air outlet 1712 are trumpet-shaped to facilitate airflow in and out of the air-cooling box 171 , enhance the narrow tube effect, and thus increase the flow rate of the airflow in the air-cooling box 171 .

[0083] Furthermore, the air catching port 1171 may be in a 360° trumpet shape to increase the volume of the airflow entering the air catching port 1171 and enhance the narrow tube effect.

[0084] Optionally, the lifeboat energy compensation system further includes a water cooling device 18, which includes a water cooling tank 181 and a water pump 182. The water cooling tank 181 has a first inlet, a second inlet, and a first outlet. The first inlet pipe is connected to the four-stage turbine generator 1142, and the second inlet pipe is connected to the water pump 182. The water pump 182 is used to pump cold seawater to the water cooling tank 181. The first outlet pipe is connected to the fourth heat exchange tank. Using cold seawater to water-cool the four-stage working fluid after power generation can cause the gaseous four-stage working fluid to condense into liquid, which is beneficial for increasing the temperature difference between the heat source and the working fluid, so that the heat source heats and evaporates the working fluid to drive power generation, thereby improving the efficiency of working fluid recycling and power generation efficiency. At the same time, using water cooling to cool the four-stage working fluid can facilitate the replenishment of the cooling working fluid (seawater), thereby saving energy consumption and improving power generation efficiency.

[0085] Please refer again Figure 5 In some embodiments, as can be seen from the above, the primary working fluid is seawater. Based on this, the lifeboat energy compensation system also includes a fresh water storage tank 19. The fresh water storage tank 19 is connected to the last power generation module (i.e., the fourth power generation module 114) in the secondary power generation module through a pipeline. The primary working fluid after power generation and the primary waste heat working fluid (i.e., water vapor) after heating the various levels of working fluid are stored in the fresh water storage tank 19.

[0086] In this way, on the one hand, it is convenient to replenish the first-level working fluid and compensate the energy of the lifeboat. On the other hand, the seawater can be used as fresh water after multi-stage power generation to provide fresh water resources for the lifeboat, thereby making full use of the first-level working fluid and improving energy utilization.

[0087] Optionally, considering that the heat source of the fifth power generation unit 114a is water vapor and the heat source of the sixth power generation unit 114b is the tertiary waste heat working medium, based on this, the fresh water storage tank 19 is connected to the fourth heat exchange tank of the fifth power generation unit 114a, so that water vapor can be collected as a fresh water resource.

[0088] Please combine Figure 5 and Figure 9 Optionally, the lifeboat energy compensation system also includes a fresh water filter device 20, which is arranged between the four-stage heat exchange box 1141 and the fresh water storage tank 19. The fresh water filter device 20 is used to filter the seawater after the four-stage power generation. The seawater is stored in the fresh water storage tank 19 after filtration for safe drinking by people on the lifeboat.

[0089] Optionally, the freshwater filtration device 20 includes multiple filter cartridges 201. For example, three filter cartridges 201 are filled with activated carbon, biochemical cotton, and ammonia-absorbing stone, respectively. Water vapor or water droplets after four-stage power generation are filtered and liquefied through the activated carbon, biochemical cotton, and ammonia-absorbing stone in sequence, and then flow through a pipeline into the freshwater storage tank 19 for storage. This ensures the cleanliness of the freshwater resource and facilitates drinking by people on the lifeboat.

[0090] Please combine Figures 10 to 12 In some embodiments, the heat collecting device 12 includes a solar preheater 121, a focusing structure 122 and a heat conducting structure. The solar preheater 121 is used to preheat the primary working fluid, and the focusing structure 122 is used to focus solar energy onto the heat conducting structure. The heat conducting structure extends into the primary heating module and contacts the primary working fluid.

[0091] In this way, the first-level working fluid is preheated by the solar preheater 121, and then the solar heat is transferred to the first-level heat exchange box 1111 through the focusing structure 122 and the heat-conducting structure to continue heating the first-level working fluid, so that the first-level working fluid is heated and evaporated to provide power generation for the first-level turbine generator 1112.

[0092] Optionally, the concentrating structure 122 includes a Fresnel lens and a rotating mount. The Fresnel lens is rotatably mounted on the rotating mount, and the rotating mount is communicatively connected to the control device 14. The control device drives the rotating mount to rotate according to the intensity of sunlight to adjust the angle of the Fresnel lens relative to the sun. This not only enables the concentrating structure 122 to automatically rotate to facilitate sun tracking, improving the concentrating structure 122's ability to capture solar energy, thereby improving the heat collection effect and the heating efficiency of the primary working fluid, but also enables the Fresnel lens to focus solar energy into a small area and generate high temperature, thereby efficiently converting solar energy into heat.

[0093] It is understandable that in other embodiments, the focusing structure 122 may also be any one of a convex lens, a reflector, a refracting mirror, etc.

[0094] Optionally, the heat-conducting structure includes a first heat-conducting member 123 and a second heat-conducting member 124. The first heat-conducting member 123 and the second heat-conducting member 124 are mounted on the primary power generation module 111. The concentrating structure 122 is used to focus solar energy onto the first heat-conducting member 123. The second heat-conducting member 124 is connected to the first heat-conducting member 123 and contacts the primary working fluid. This allows the primary working fluid to have a larger contact area with the heat-conducting structure, which is beneficial for improving heat transfer efficiency and thus increasing the heating efficiency of the primary working fluid.

[0095] Optionally, the first heat conductor 123 and the second heat conductor 124 may be solid copper tubes, and the second heat conductor 124 may be U-shaped, so as to increase the contact area between the solid copper tube and the primary working fluid, thereby facilitating rapid heating of the primary working fluid.

[0096] Optionally, the heat collection device 12 further includes a baffle 125, which is mounted on the first-stage heating module and tilted along the height of the lifeboat. The baffle 125 is used to reduce the violent swaying of the first-stage working fluid. This can reduce heat loss caused by swaying of the first-stage working fluid, thereby improving power generation efficiency.

[0097] Please refer again Figure 1 In some embodiments, the heating device 13 further includes a thermal insulation module, which includes a thermal insulation film and a heating device. The thermal insulation film is attached to the lifeboat, and the heating device is communicatively connected to the control device 14.

[0098] In this way, the provision of the thermal insulation film can help maintain the temperature inside the lifeboat, so that the temperature on the lifeboat can be kept at a suitable body temperature, avoiding the situation of frostbite caused by the low temperature environment. At the same time, the provision of the heating equipment can provide heat to the lifeboat in a timely manner to ensure the ambient temperature of the lifeboat, making the people on the lifeboat feel more comfortable. The lifeboat is heated by the waste heat heating module, the thermal insulation film and the heating equipment, which is conducive to keeping the people on the lifeboat warm.

[0099] Optionally, the material of the thermal insulation film may be any one of aluminum foil, polyethylene, polypropylene or polyurethane.

[0100] In some embodiments, the control device 14 has a dynamic adjustment function. As mentioned above, the control device 14 is communicatively connected to the detection control valve 15 and the rotating mounting base of the focusing structure 122. The control device 14 monitors the working fluid gas and air pressure values ​​at different locations (including various levels of heat exchange boxes, working fluid storage boxes, and the inlet and outlet of the flow buffer bladder, the delivery pipeline, etc.) in real time through the detection control valve 15. When an abnormal air pressure or working fluid leakage is detected, the detection control valve 15 is automatically closed to implement emergency fault handling for the lifeboat energy compensation system. When the air pressure of the flow buffer bladder is detected to increase to a preset value, the control device 14 recognizes that the working fluid in the flow buffer bladder is insufficient and needs to be replenished. At this time, the control device 14 issues an alarm signal and triggers the working fluid circulation box to replenish the working fluid to the flow buffer bladder.

[0101] Optionally, the heat-conducting structure of the heat-collecting device 12 is provided with a temperature sensor, which is communicatively connected to the control device 14. When the temperature sensor detects that the temperature of the heat-conducting structure is lower than a preset temperature, the control device 14 determines that the sunlight intensity has decreased. At this time, the control device 14 controls the rotation of the swivel mount to adjust the angle of the Fresnel lens, so that the Fresnel lens can focus more sunlight onto a single area, thereby efficiently converting solar energy into heat. In some embodiments, the lifeboat energy compensation system further includes a battery 21 and a power supply device 22. The power generation modules of the power generation device 11 are respectively connected to the battery 21, and the battery 21 stores the electricity generated by the power generation device 11. The power supply device 22 is connected to the battery 21, the heating device 13, and the control device 14. The power supply device 22 is configured to supply the electricity in the battery 21 to the heating equipment or other electrical equipment (such as communication equipment, propellers, lighting equipment, etc.) on the lifeboat under the control of the control device 14.

[0102] In some embodiments, the lifeboat energy compensation system further includes a shock absorbing device, and the power generation device 11, the heating device 13, the water cooling device 18, and the power supply device 22 are installed on the hull through the shock absorbing device, thereby reducing the impact of mechanical vibration and impact caused by waves on the device and improving the reliability of the lifeboat energy compensation system.

[0103] Optionally, the shock absorbing device may be any one of a spring shock absorber and a rubber shock absorbing pad, which may be configured according to actual needs and is not limited here.

[0104] Optionally, components of the lifeboat energy compensation system are constructed of corrosion-resistant materials (such as stainless steel and titanium alloy) and coated with an anti-corrosion coating (such as epoxy resin or Teflon), especially those in direct contact with seawater (such as the seawater pump). This provides an additional layer of protection, preventing direct contact between seawater and components, extending the service life of the components and ultimately increasing the reliability of the lifeboat energy compensation system.

[0105] Optionally, to reduce performance degradation due to wear of mechanical components over long-term operation, components of the lifeboat energy compensation system are constructed from wear-resistant materials, such as cemented carbide for the turbine generator. Furthermore, effective lubrication measures are employed to reduce friction between components and extend their service life.

[0106] Please combine Figure 13 In a second aspect, the present application further provides an energy utilization method, which is applied to the lifeboat energy compensation system as described in the first aspect above, and the energy utilization method comprises:

[0107] S100, the heat collecting device absorbs solar energy and heats the primary working fluid of the power generation device.

[0108] S200, the first-level working fluid is heated and evaporated, and then passes through the first-level power generation module to generate electricity and form the first-level waste heat working fluid.

[0109] S300: The first-stage waste heat working fluid heats the working fluid of the next-stage power generation module.

[0110] S400, the first-stage waste heat working fluid and the heated first-stage working fluid are transported to the waste heat heating module for heating.

[0111] In this way, solar energy is used to heat and evaporate the first-level working fluid to drive the first-level turbine generator to generate electricity, thereby being able to compensate energy for the lifeboat in a timely manner, so that the lifeboat has sufficient energy reserves and the safety of the lifeboat is improved. At the same time, the first-level waste heat working fluid can be used to heat the working fluid of the next-level power generation module, which is conducive to utilizing the waste heat of the working fluid, improving the power generation efficiency, and thus improving the energy utilization rate. Moreover, by setting up the first-level working fluid and the first-level waste heat working fluid, they can be used to provide heating for the people on the lifeboat, which is conducive to the efficient and reasonable use of thermal energy, further improving the energy utilization rate.

[0112] It can be understood that, since the energy utilization method includes the lifeboat energy compensation system described in the first aspect above, the energy utilization method has the beneficial effects of the lifeboat energy compensation system described in the first aspect above, which will not be described in detail here.
