Description

Technical Field

[0001] The present invention belongs to the field of nuclear power technology, and in particular relates to a mobile marine nuclear charging station and a submarine distributed charging system. Background Art

[0002] Underwater equipment, such as submarines, unmanned underwater vehicles, and underwater robots, plays a vital role in seabed exploration, resource development, and reconnaissance patrols. Furthermore, underwater operations typically last for months or even years, placing high demands on equipment endurance and concealment. However, traditional underwater mobile equipment often relies on batteries for power. Limited by their energy density, their single-charge endurance is insufficient, requiring frequent returns to the surface or even land for recharging, significantly limiting the equipment's performance. Existing underwater charging devices include those towed by a mother ship and those fixed on the seabed, designed to power mid-seawater and seabed equipment, respectively.

[0003] The mother ship towing charging method is that the mother ship tows the charging device through the umbilical cable to provide power for it, moves it to the vicinity of the equipment to be charged, and guides it to connect with the charging device to replenish power. For example, the document number CN111874168A "A mobile cable-free underwater robot deployment, recovery and charging device" and the document number CN116714453A "UUV underwater charging device and charging method" both disclose that the mother ship charges the underwater equipment. In this method, the charging device is movable, but its mother ship needs to move on the sea surface, and its concealment is poor; at the same time, considering the movement of the charging device underwater, the length of the umbilical cable is limited, and the equipment to be charged needs to float to near the water surface, which limits the working efficiency of the underwater equipment.

[0004] The submarine fixed charging device is a platform fixed on the seabed by legs, and provides power to underwater equipment through the energy storage device carried by the platform itself or by laying cables from land to the seabed. For example, the solution disclosed in document number CN112636422A "A Submarine Distributed Relay Charging System and Method" is to obtain power from a shore-based remote power supply through a main power supply network laid in an underwater grid structure. Multiple underwater charging stations are arranged at intervals on the grid structure of the main power supply network, and non-contact charging is used to charge underwater mobile equipment. Although it can charge equipment on the seabed, it obtains power through submarine cables. At present, laying submarine cables from the shore to the deep sea is consuming and costly, and the layout position is fixed, which cannot be flexibly deployed. Summary of the Invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a mobile nuclear charging station in the sea area which has a simple structure and can dive or float in the water to charge underwater or surface equipment.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a mobile nuclear charging station in the sea, comprising a nuclear power source and a power output device, wherein the power output device is electrically connected to the nuclear power source, the nuclear power source having a shell and a supercritical CO2 power generation assembly connected thereto, the supercritical CO2 power generation assembly being installed in the shell, and the shell being a sandwich shell, and forming a cavity in the sandwich shell, the supercritical CO2 power generation assembly being used to generate electricity and adjust the water-gas ratio in the cavity to drive the nuclear power source to float or dive in the water, and the power output device being used to supply power to the outside.

[0007] The beneficial effect of the above technical solution is that the nuclear power source can continue to operate in the corresponding sea area. At the same time, it can use the supercritical CO2 power generation assembly to adjust the water-gas ratio in the cavity so that the nuclear power source can float or dive in the water. During the floating or diving process, the power output device of the nuclear power source can charge underwater equipment or surface equipment. In particular, the nuclear power source can be hidden underwater, which makes it well concealed.

[0008] In the above technical solution, the center of gravity of the nuclear power supply is biased downward, and the outer lower end of the shell has a first opening that penetrates the cavity, and a first valve is provided at the first opening.

[0009] The beneficial effect of the above technical solution is that: by shifting the center of gravity of the nuclear power supply downward, the nuclear power supply can always maintain a vertical state in water (similar to a tumbler), and a first opening is provided at the outer lower end of the shell, and a first valve is provided at the first opening. When the first valve is opened, water from the outside can enter the cavity, thereby adjusting the water-gas ratio in the cavity.

[0010] In the above technical solution, the inner upper end of the shell is provided with a second opening and a third opening that pass through the cavity, and the second opening is connected to the high-pressure end of the supercritical CO2 power generation assembly, and a second valve is provided at the connection point. The third opening is connected to the low-pressure end of the supercritical CO2 power generation assembly, and a third valve is provided at the connection point.

[0011] The beneficial effect of the above technical solution is that when the first valve is opened, the second valve or the third valve can be selectively opened to adjust the water-gas ratio in the cavity. Specifically, when the second valve is opened, the high-pressure end of the supercritical CO2 power generation assembly adds gas to the cavity and squeezes out the water in the cavity, thereby causing the nuclear power source to float. When the third valve is opened, the CO2 in the cavity flows back to the low-pressure end of the supercritical CO2 power generation assembly, and water is sucked into the cavity, thereby causing the nuclear power source to dive.

[0012] The supercritical CO2 power generation assembly in the above technical solution includes a high-pressure gas storage tank and a low-pressure gas storage tank. The second opening is connected to the high-pressure gas storage tank, and the third opening is connected to the low-pressure gas storage tank. The high-pressure gas storage tank constitutes the high-pressure end of the supercritical CO2 power generation assembly, and the low-pressure gas storage tank constitutes the low-pressure end of the supercritical CO2 power generation assembly.

[0013] The beneficial effect of the above technical solution is that when the nuclear power source is floating, the high-pressure gas tank supplies CO2 to the cavity through the second opening, and when the nuclear power source is diving, the low-pressure gas tank collects CO2 in the cavity through the third opening.

[0014] The nuclear power source in the above technical solution also includes a nuclear reactor installed in the shell, and the nuclear reactor is used to supply energy to the supercritical CO2 power generation assembly.

[0015] The beneficial effect of the above technical solution is that the supercritical CO2 power generation assembly is powered by the nuclear reactor, so that the supercritical CO2 power generation assembly continuously generates electrical energy and supplies power to the power output device.

[0016] The power output device in the above technical solution is an underwater movable plug, and the power output device is electrically connected to the nuclear power supply through a cable, and the power output device moves underwater with its own power.

[0017] The beneficial effect of the above technical solution is that the power output device can be moved underwater to dock with underwater equipment or surface equipment for external charging.

[0018] The core power supply in the above technical solution is further provided with a cable reel, which is used to retract and release the cable.

[0019] The beneficial effect of the above technical solution is that when the nuclear power source does not need to supply power to the outside, the cable can be reeled in by the cable reel.

[0020] The power output device in the above technical solution includes an underwater vehicle, an underwater plug body and an identification and positioning probe. The underwater plug body and the identification and positioning probe are installed on the underwater vehicle, and the underwater vehicle is electrically connected to the corresponding end of the cable.

[0021] The beneficial effect of the above technical solution is that the underwater vehicle provides submersible power for the power output device, and the identification and positioning probe is used to identify and locate the charging port of the surface equipment or underwater equipment.

[0022] The above technical solution also includes an anchor cable, one end of which is anchored on the seabed, and the other end of which is connected to the nuclear power source.

[0023] The beneficial effect of the above technical solution is that it can prevent the nuclear power source from being drifted away by the waves.

[0024] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: a submarine distributed charging system, comprising a charging seat, multiple submarine charging stations and the sea mobile nuclear charging station as described above, wherein the multiple submarine charging stations are distributed in a matrix on the seabed in the area where the sea mobile nuclear charging station is located, and the multiple submarine charging stations are electrically connected in a mesh shape, the charging seat is electrically connected to any one of the submarine charging stations, and the sea mobile charging station is used to charge the submarine charging station.

[0025] The beneficial effect of the above technical solution is that it makes the functions of the submarine distributed charging system more diverse. The mobile nuclear charging station in the sea area can flexibly charge surface equipment and underwater equipment, and its excess electricity can be stored by the submarine charging station, and the submarine charging station can also charge underwater equipment.

DETAILED DESCRIPTION

[0033] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in exact proportions. They are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention.

[0034] Example 1

[0035] like Figure 1-Figure 3 As shown, this embodiment provides a mobile nuclear charging station in the sea, including a nuclear power source 1, a cable 2 and a power output device 3. The nuclear power source 1 and the power output device 3 are both placed in water. The nuclear power source 1 has a water tank and a supercritical CO2 power generation assembly 13 connected thereto. The supercritical CO2 power generation assembly 13 is used to generate electricity and adjust the water-gas ratio in the water tank to adjust the nuclear power source 1 to float or dive in the water. The power output device 3 is electrically connected to the nuclear power source 1 through the cable 2. The power output device 3 can be a mobile underwater power output device, which has its own power and can move underwater. In this way, the nuclear power source can continue to operate in the corresponding sea area and be moved by the power output device to supply power to the surrounding underwater equipment or surface equipment. Charging operations are carried out, especially the nuclear power supply can be submerged underwater, which makes it well concealed; specifically, the nuclear power supply 1 also includes a shell 11 and a nuclear reactor 12, the nuclear reactor 12 and the supercritical CO2 power generation assembly 13 are both arranged in the shell 11, the nuclear reactor 12 is used to supply energy to the supercritical CO2 power generation assembly 13, the cable 2 is inserted into the shell 11, and is electrically connected to the supercritical CO2 power generation assembly 13, the water tank is arranged on the shell 11, so that the shell can provide a closed installation space for the nuclear reactor and the supercritical CO2 power generation assembly, and the nuclear reactor supplies energy to the supercritical CO2 power generation assembly, so that the supercritical CO2 power generation assembly generates electricity and supplies power to the power output device.

[0036] In this embodiment, the shell may be a spherical shell or a teardrop-shaped shell, the nuclear reactor is a small nuclear reactor, and the nuclear reactor and the supercritical CO2 power generation assembly are both existing technologies and will not be described in detail here.

[0037] like Figure 1-Figure 3As shown, in the above technical solution, the shell 11 is a sandwich shell with a cavity 111 inside, and the cavity 111 constitutes the water tank, and the center of gravity of the nuclear power source 1 is biased downward, and the outer lower end of the shell 11 has a first opening 112 that is connected to the cavity 111 (the first opening is connected to the outside world, and the cavity can take in or drain water through the first opening), and a first valve 113 is provided at the first opening 112. The inner upper end of the shell 11 is provided with a second opening 114 and a third opening 115 that are connected to the cavity 111, and the second opening 114 is connected to the high-pressure end of the supercritical CO2 power generation assembly 13, and a second valve 116 is provided at the connection, and the third opening 115 is connected to the low-pressure end of the supercritical CO2 power generation assembly 13, and is connected at the connection. A third valve 117 is provided, the first valve 113 is opened, and the second valve 116 and the third valve 117 are selectively opened to adjust the water-gas ratio in the cavity 111; by lowering the center of gravity of the nuclear power supply, the nuclear power supply can always maintain a vertical state in the water (similar to a tumbler), and the shell is provided as a sandwich shell, and a cavity is provided inside, and the cavity matches the first opening, the second opening and the third opening, wherein the first opening is used to introduce water into or discharge water into the cavity, and the second opening is used to discharge CO2 in the supercritical CO2 power generation assembly into the cavity, and the third opening is used to discharge CO2 in the cavity to the supercritical CO2 power generation assembly, in this way, the water-gas ratio in the cavity (i.e., the volume ratio of water and gas) can be adjusted, thereby adjusting the nuclear power supply to float or dive in the water.

[0038] In this embodiment, the method of shifting the center of gravity of the nuclear power supply downward can be to install the nuclear reactor and the supercritical CO2 power generation assembly at the inner lower end of the shell, and shifting the center of gravity of the nuclear power supply downward can prevent the nuclear power supply from being turned upside down in water (thereby ensuring that the first opening is always located at the lower end of the shell, and the second opening and the third opening are always located at the upper end of the shell). Specifically, in this embodiment, the shell may include an inner shell and an outer shell, and the inner shell is placed in the outer shell, and there is a gap between the two to form a cavity. The inner shell and the outer shell can be connected by multiple support rods, which can prevent the inner shell from moving in the outer shell without affecting the volume of the cavity. The first opening is located at the lower end of the outer shell, and the second opening and the third opening are arranged at the upper end of the inner shell.

[0039] like Figure 3As shown, the supercritical CO2 power generation assembly 13 in the above technical solution includes a high-pressure gas storage tank 131 and a low-pressure gas storage tank 132, the second opening 114 is connected to the high-pressure gas storage tank 131, and the third opening 115 is connected to the low-pressure gas storage tank 132. The high-pressure gas storage tank 131 constitutes the high-pressure end of the supercritical CO2 power generation assembly 13, and the low-pressure gas storage tank 132 constitutes the low-pressure end of the supercritical CO2 power generation assembly 13. In this way, when the nuclear power source floats up, the high-pressure gas storage tank supplies CO2 to the cavity through the second opening, and when the nuclear power source dives, the low-pressure gas storage tank collects CO2 in the cavity through the third opening.

[0040] Specifically, when the nuclear power source does not need to float or dive, the first valve, the second valve and the third valve are all in a closed state. If the nuclear power source needs to dive, the first valve and the third valve are opened at this time, and the second valve remains closed. At this time, water will enter the cavity through the first opening and discharge the CO2 in the cavity to the low-pressure gas storage tank 132 (the CO2 in the cavity cannot be completely discharged, otherwise water will enter the low-pressure gas storage tank). At this time, the water in the cavity will increase, so its density will increase, so it dives; when the nuclear power source dives to the required depth, the first valve and the third valve are closed at this time; if the nuclear power source needs to float, the first valve and the second valve are opened at this time, and the third valve remains closed. At this time, the CO2 in the high-pressure gas storage tank will be partially discharged into the cavity (the water in the cavity cannot be completely discharged, otherwise the CO2 will be discharged outside the shell, which can avoid the loss of CO2 gas in the supercritical CO2 power generation assembly 13), and the water in the cavity will be squeezed out through the first opening. At this time, the water in the cavity will decrease, so its density will decrease, so it floats.

[0041] The nuclear power source described in this embodiment can float up or dive down without the need for external power.

[0042] like Figure 1 and Figure 2 As shown, in the above technical solution, a receiving groove 118 is recessed on the outer wall of the shell 11, and a cable reel 21 is provided in the receiving groove 118. The cable 2 is wound on the cable reel 21, and the cable reel 21 is used to retract and release the cable 2. In this way, when the nuclear power supply does not need to supply power to the outside, the cable reel will reel the cable and enable the power output device to be stored in the receiving groove.

[0043] The accommodating groove is recessed in the side of the shell, and an electronic slip ring is provided at the reel of the cable reel, and the cable is electrically connected to the nuclear power supply through the electronic slip ring, so that when the cable reel reels the cable, it does not affect the electrical connection between the cable and the nuclear power supply. The cable reel can adopt a cable retraction device similar to the one disclosed in document number CN217102545U "A composite cable retraction device", and only its electronic components need to be replaced by waterproof electronic components.

[0044] like Figure 5 As shown, the above technical solution also includes an anchor cable 4, one end of which is anchored to the seabed, and the other end of which is connected to the lower end of the shell 11, so as to prevent the nuclear power source from being drifted away by the waves. The length of the anchor cable can be slightly greater than the depth of the sea water at high tide, so that the nuclear power source can float on the water surface and have a certain range of movement above the sea surface. It can also sink to the seabed, but will not be drifted away by the waves. Figure 5 A represents the seabed. In this embodiment, the anchor cable can be a steel wire rope, and the lower end of the anchor cable can be sunk to the seabed through a counterweight block, or anchored to the seabed using an anchor hook.

[0045] like Figure 4 As shown, the power output device 3 in the above technical solution includes an underwater vehicle 31, an underwater plug body 32, and an identification and positioning probe 33. The underwater plug body 32 and identification and positioning probe 33 are mounted on the underwater vehicle 31. The underwater vehicle 31 is electrically connected to the corresponding ends of the cable 2. This allows the underwater vehicle to provide submersible power for the power output device, while the identification and positioning probe is used to identify and locate the charging port of surface equipment or underwater equipment. The power output device 3 can be similar to the combination of a remote-controlled unmanned submersible and a charging station disclosed in CN111874168A, "A Mobile Cable-Free Underwater Robot Deployment, Recovery, and Charging Device." The identification and positioning probe 33 is added to this combination to enable the underwater vehicle to automatically dock the underwater plug body 32 with the charging port when approaching the surface equipment or underwater equipment. The identification and positioning probe can be similar to the combination of an ultrasonic sensor, a laser ranging sensor, and a CCD sensor disclosed in CN104795868B, "Automatic Charging System for Electric Vehicles."

[0046] like Figure 5As shown, the above technical solution also includes a control assembly 5 arranged in the shell 11 and a communication module 6 arranged on the outer wall of the shell 11. The power output device 3, communication module 6, nuclear reactor 12, supercritical CO2 power generation assembly 13, first valve 113, second valve 116 and third valve 117 (all are electric valves) are all electrically connected to the control assembly 5. In this way, the entire sea mobile nuclear charging station can communicate with the outside world through the communication module, and the control assembly controls the operating status of the entire sea mobile nuclear charging station according to external instructions. The communication module can adopt an underwater wireless communication module (UWC), which belongs to the existing technology and is not described in detail here. The control assembly in this embodiment can adopt an industrial computer.

[0047] like Figure 1 and Figure 2 As shown, in the above technical solution, multiple cables 2 and multiple power output devices 3 are provided, and the multiple cables 2 correspond to the multiple power output devices 3 one by one. One end of each cable 2 is electrically connected to the core power supply 1, and the other end is electrically connected to the power output device 3, so that the core power supply can charge multiple surface equipment or underwater equipment at the same time.

[0048] The cable in this embodiment can be a composite cable (including a power supply cable and a communication cable, so that the core power supply and the power output device 3 can both supply power and communicate). The cable in this embodiment should preferably be a relatively soft cable so that it is easy to reel.

[0049] The mobile nuclear charging station in the sea area described in this embodiment can achieve self-sufficiency in electricity and can also supply surplus electricity to the outside to serve as a charging station.

[0050] Example 2

[0051] like Figure 6As shown, this embodiment provides a submarine distributed charging system, including a charging seat 300, a plurality of submarine charging stations 200 and the mobile nuclear charging station 100 in the sea area as described in Example 1, wherein the plurality of submarine charging stations 200 are distributed in a matrix on the seabed in the area where the mobile nuclear charging station 100 is located, and the plurality of submarine charging stations 200 are electrically connected in a meshed manner, and the charging seat 300 is electrically connected to any one of the submarine charging stations 200 (the charging seat 300 cooperates with the underwater plug body 32, and the power output device 3 The underwater plug body 32 can be moved to the underwater plug body 32 and connected to the charging seat 300 to charge the submarine charging station 200). The marine mobile charging station 100 is used to charge the submarine charging station 200, and the submarine charging station can supply power to the outside (to charge underwater equipment). This makes the submarine distributed charging system more versatile. The marine mobile nuclear charging station can flexibly charge surface equipment and underwater equipment, and its excess electricity can be stored by the submarine charging station, and the submarine charging station can also charge underwater equipment. In this embodiment, each of the submarine charging stations 200 has a storage battery for storing electricity. The connection diagram of multiple submarine charging stations 200 in this embodiment is similar to the connection diagram of multiple underwater charging stations in the document number CN112636422A "A Submarine Distributed Relay Charging System and Method".

[0052] The charging seat 300 and the underwater plug body 32 described in this embodiment are equivalent to a pair of underwater electrical connectors, which can be similar to the electrical connector disclosed in document number CN107910699B "A Pressure Balanced Underwater Plug-in Electrical Connector".

[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
