[0029] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings:

[0030] like Figure 1 , an underwater energy storage and pressure-resistant device with diversion and heat dissipation functions, comprising a shell, the inner cavity of the shell is used to place a square columnar energy storage device 7.

[0031] The housing is a double-layer structure, comprising an outer shell and an inner liner. An insulation layer is provided between the two to reduce the impact of external temperatures on the energy storage components. Furthermore, the housing is welded together from three parts: an upper end cap 1, a cylindrical body 2, and a lower end cap 5. Each layer is a double-layer structure, and the insulation layers of the three parts are connected as one.

[0032] The underwater energy storage and pressure-resistant device also includes a heat sink, a flow guide system and a circulating heat dissipation system.

[0033] The heat sinks include a plurality of first heat sinks 6 mounted on the left and right outer walls of the energy storage device 7, and a plurality of second heat sinks 12 mounted on the front and rear outer walls of the energy storage device 7. The heat sinks on the same side are evenly distributed along the height direction, while the first heat sinks 6 and second heat sinks 12 on adjacent outer walls are staggered along the height direction. The heat sinks are made of metal and have an anti-corrosion coating on the outer surface to prevent corrosion in underwater environments.

[0034] like Figure 2 、 3, 4. The air guide system includes a longitudinal air guide tube 3 arranged along the front-to-back direction and a transverse air guide tube 4 arranged along the left-to-right direction. The longitudinal air guide tube 3 is in close contact with the first heat sink 6 in a one-to-one correspondence, and the transverse air guide tube 4 is in close contact with the second heat sink 12 in a one-to-one correspondence. All the air guide tubes on the same side are evenly distributed along the height direction.

[0035] Both ends of the longitudinal flow guide pipe 3 are connected to the first connection port 2 - 1 opened on the cylindrical body 2 by welding, and both ends of the transverse flow guide pipe 4 are connected to the second connection port 2 - 2 opened on the cylindrical body 2 by welding.

[0036] Further, if Figure 5 The flow diversion system also includes auxiliary piping located outside the housing. All diversion pipes are connected in parallel through these auxiliary piping and connected to an inlet manifold and an outlet manifold. The inlet manifold has a water inlet, and the outlet manifold has a water outlet. This parallel structure significantly increases the cooling water flow rate.

[0037] The circulating heat dissipation system includes a circulating pump 13 and a radiator 14. The water inlet of the circulating pump 13 is connected to the water outlet of the diversion system, and the water outlet is connected to the water inlet of the radiator 14. The water outlet of the radiator 14 is connected to the water inlet of the diversion system.

[0038] During operation, the energy storage device 7 generates a significant amount of heat, which is absorbed by the heat sink and transferred to the closely contacted longitudinal or transverse flow conduits 3 and 4. High-temperature cooling water in the flow conduits, driven by a circulating pump 13, reaches the radiator 14, where it exchanges heat with the cold external environment, dissipating the heat. The cooled, low-temperature cooling water then returns to the housing, achieving circulated heat dissipation for the energy storage device 7.

[0039] Further, if Figure 1 and 2 A temperature sensor 8 for detecting the temperature of the energy storage device 7 is also installed in the housing. The temperature sensor 8 is installed on the energy storage device 7, preferably on the top of the energy storage device 7. In this embodiment, the temperature sensor 8 is a thermocouple or a thermal resistor sensor with high measurement accuracy, which can accurately reflect the temperature changes of the energy storage device 7.

[0040] The housing also houses a photoelectric converter 9 for converting the electrical signal output by the temperature sensor 8 into an optical signal. In this embodiment, the photoelectric converter 9 is a fiber Bragg grating temperature sensor demodulator. This converter converts the electrical temperature signal into an optical signal and transmits it to an external monitoring device via an optical cable. This converter offers advantages such as strong anti-interference capabilities and long transmission distances.

[0041] Furthermore, a watertight connector 10 is mounted on the upper end cap 1, through which the photoelectric converter 9 is electrically connected to an external photoelectric composite cable 11. The photoelectric composite cable 11 comprises two optical cables and four electrical cables. The optical cables are used to transmit optical signals. Waterproof optical cables are designed to operate properly in underwater environments, ensuring stable transmission of temperature signals. The electrical cables are used to power the photoelectric converter 9 and the temperature sensor 8.

[0042] Temperature sensor 8 monitors the temperature of energy storage device 7 in real time. Photoelectric converter 9 converts the temperature signal into an optical signal, which is transmitted via an optical cable to an external monitoring device. The external monitoring device displays the temperature information of energy storage device 7 in real time, allowing operators to keep abreast of the device's operating status.
