[0002] Dredgers are vessels specially used for clearing silt from rivers, lakes and ports. During these processes, dredgers require a stable power supply to drive their various mechanical equipment. Battery packs can serve as backup or auxiliary power sources for dredgers, ensuring that dredgers can continue to work stably when the main power supply fails or additional power is needed. Battery packs can help reduce ships' dependence on traditional energy sources such as diesel, thereby reducing emissions and pollution. The air moisture content in rivers and coastal areas is indeed relatively large, and the air humidity around the hull is relatively high, especially in summer or during periods of higher temperatures, when evaporation is more significant and the air moisture content is greater.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0019] See also Figures 1 to 10 The present invention provides a technical solution: a ship energy supply system, comprising: a housing 1, a battery pack 2 is arranged inside the housing 1, the whole ship is powered by the battery pack, the structure is compact, space is saved, it is easy to implement, the equipment maintenance and replenishment are simple, the working stability is good, and the safety is high; It also includes: a dehumidification component 3, which is arranged at the bottom of the housing 1, and the dehumidification component 3 rotates the airflow to achieve heat dissipation, and at the same time, realizes the liquefaction dehumidification operation of the flowing air and collects the liquid obtained by dehumidification; A monitoring component 4 is provided on the inner wall of the outer shell 1. A connecting component 6 is provided at the bottom of the dehumidification component 3. The temperature inside the outer shell 1 is monitored by the monitoring component 4. When the temperature exceeds the standard and the airflow rotation heat dissipation effect cannot completely dissipate the heat, the connecting component 6 is controlled to work. A heat dissipation component 7 is provided inside the battery pack 2. The coolant circulates inside the heat dissipation component 7 to realize the switching operation of coolant heat dissipation for the battery pack 2. The battery pack 2 is cooled by airflow through the dehumidification component 3. When the monitoring component 4 detects that the temperature exceeds the standard and the heat dissipation effect of the airflow heat dissipation is weakened, the connecting component 6 is operated to work. The movement of the connecting component 6 drives the circulation of the coolant inside the heat dissipation component 7, and the heat inside the battery pack 2 is driven by heat-cold exchange, so as to realize the rapid cooling operation of the battery pack 2 with excessive temperature.

[0020] The dehumidification component 3 includes a base 31 fixed to the bottom of the shell 1, and a liquefaction chamber 32 is evenly opened inside the base 31. The liquefaction chamber 32 is configured to be wavy. When water vapor outside the base 31 enters the inside of the liquefaction chamber 32, the water vapor encounters the colder surface of the liquefaction chamber 32, and the water vapor loses heat and begins to liquefy. The water vapor condenses into liquid water on the wall of the liquefaction chamber 32 and flows along the inner wall to the bottom of the liquefaction chamber 32, thereby realizing the dehumidification operation of the air.

[0021] A fan shell 33 is provided at the top of the center of the base 31, and a connecting frame 1 34 is fixed to the top of the fan shell 33, a connecting frame 2 35 is fixed to the bottom of the fan shell 33, a motor 36 is fixed to the center of the connecting frame 1 34, and a rotating rod 37 is fixed to the output shaft of the motor 36, and a heat dissipation leaf 38 is fixed to the outer wall of the rotating rod 37. When the battery pack 2 is working, the motor 36 works synchronously, and the motor 36 drives the rotating rod 37 to rotate, and the rotating rod 37 drives the heat dissipation leaf 38 to rotate synchronously. The rotation of the heat dissipation leaf 38 drives the circulation of air inside the battery pack 2 to achieve airflow heat dissipation of the battery pack 2.

[0022] The monitoring component 4 includes a sealed box 41 fixed to the inner wall of the shell 1, and a water storage chamber 42 is opened inside the sealed box 41, a floating plate 43 is arranged inside the water storage chamber 42, moving rods 44 are fixed on both sides of the floating plate 43, and a protective plate 45 is fixed on the outer wall of the moving rod 44, openings 46 cooperating with the moving rod 44 are opened on both sides of the sealed box 41, and a touch switch 47 is fixed at the bottom of the opening 46. The water storage chamber 42 is loaded with liquid water. When the battery pack 2 is at noon, the temperature rises rapidly, the liquid water inside the water storage chamber 42 evaporates rapidly, the liquid water inside the water storage chamber 42 decreases, the water level drops, and the floating plate 43 is driven to move downward synchronously. The floating plate 43 drives the moving rod 44 to move downward synchronously. After the moving rod 44 moves downward, it presses the touch switch 47. After the touch switch 47 is contacted, it receives a signal of the water level drop. At this time, it is judged that the temperature exceeds the standard.

[0023] The lower end of the liquefaction chamber 32 is connected to one end of the guide pipe 52, the other end of the guide pipe 52 is connected to the water collecting pipe 53, the side of the water collecting pipe 53 close to the fan shell 33 is connected to one end of the water supply pipe 54, and the other end of the water supply pipe 54 is connected to the water storage chamber 51, the water storage chamber 51 is opened inside the base 31, and the liquid water accumulated at the bottom of the liquefaction chamber 32 is collected and guided by the guide pipe 52, so that the liquid water enters the inside of the water collecting pipe 53. When the rotating blade 66 rotates, the airflow generated by the rotation of the rotating blade 66 draws the air inside the water supply pipe 54, so that the liquid water inside the water collecting pipe 53 enters the inside of the water storage chamber 51 through the water supply pipe 54, thereby realizing the storage operation of liquid water.

[0024] A water outlet 55 is provided at the bottom of the water storage chamber 51, and the bottom of the water outlet 55 is connected to the water collecting port 56. The water source stored in the water storage chamber 51 enters the interior of the water collecting port 56 through the water outlet 55, which is beneficial for the coolant stored in the water storage chamber 51 to be indirectly transmitted to the interior of the battery pack 2 through the water collecting port 56, thereby performing liquid cooling for the battery pack 2.

[0025] The connecting component 6 includes an electromagnet 1 61 fixed at the bottom of the rotating rod 37, and an electromagnet 2 62 is provided at the bottom of the electromagnet 1 61. When the monitoring component 4 detects a signal that the temperature exceeds the standard, the electromagnet 1 61 is energized. After being energized, the electromagnet 1 61 becomes magnetic and attracts the electromagnet 2 62. The electromagnet 2 62 is attracted by the electromagnet 1 61 and moves upward, realizing the auxiliary operation of rapid liquid cooling, which is beneficial to the rapid and timely cooling of the battery pack 2 in a high temperature state.

[0026] The bottom of the second electromagnet 62 is fixed with an insert cylinder 63, and an insert cavity 64 is provided inside the insert cylinder 63, an insert rod 65 is inserted inside the insert cavity 64, and the bottom of the insert rod 65 is rotatably connected to the inner wall of the water storage chamber 51 through a bearing, and a rotating leaf 66 is fixed to the outer wall of the insert cylinder 63. When the second electromagnet 62 moves up, the second electromagnet 62 drives the insert cylinder 63 to move up synchronously, and the insert rod 65 slides inside the insert cavity 64. When the rotating rod 37 rotates, the insert cylinder 63 is indirectly driven to rotate synchronously through the first electromagnet 61 and the second electromagnet 62, and the insert cylinder 63 drives the rotating leaf 66 to rotate synchronously. The rotation of the blades 66 drives the liquid water stored in the water storage chamber 51 to rotate, and the rotation of the liquid water drives the water flow. Through the above design, when the temperature is high and the heat dissipation method of rotating the heat dissipation blades 38 cannot completely dissipate the heat, the electromagnet 1 61 is connected with the electromagnet 2 62 to drive the rotating blades 66 to operate. The operation of the rotating blades 66 realizes the flow of liquid water, and the coolant enters the interior of the battery pack 2 to exchange heat with the hot air inside the battery pack 2, thereby achieving the purpose of rapid cooling, and avoiding the battery pack 2 being in a high temperature state for a long time and affecting the operation of the internal parts of the battery pack 2.

[0027] The insertion rod 65 is set to a "+" shape, and the interior of the insertion cavity 64 is set to a "+" shape that matches the insertion rod 65. The top of the rotating leaf 66 is tilted upward. Through the design of the insertion cavity 64 and the insertion rod 65, the insertion rod 65 can be extended and retracted inside the insertion cavity 64. The rotation of the insertion tube 63 drives the insertion rod 65 to rotate synchronously, which is beneficial to the rapid docking of the electromagnet 2 62 with the electromagnet 1 61 after the electromagnet 2 62 rises, and the docking of the electromagnet 2 62 with the electromagnet 2 62 is released when the electromagnet 2 62 descends, making the lifting and lowering of the insertion tube 63 more stable.

[0028] Water pipe 1 71 is connected to both sides of the water collecting port 56, and both sides of the top of water pipe 1 71 are connected to heat absorption pipe 2 73, the middle part of the top of water pipe 1 71 is connected to one end of heat absorption pipe 1 72, one end of heat absorption pipe 2 73 away from water pipe 1 71 is connected to one end of water pipe 2 74, the other end of water pipe 2 74 and the other end of heat absorption pipe 1 72 are connected to return pipe 75, water pipe 3 76 is fixed to the bottom of return pipe 75, and the bottom end of water pipe 3 76 is inserted into the lower end of the water storage chamber 51, when the coolant enters the water collecting port 56, the coolant impacts the top of water pipe 1 71, and most of the coolant enters the absorption chamber 51. A small amount of coolant enters the interior of the heat absorption tube 1 72 inside the heat absorption tube 2 73, and the coolant entering the interior of the heat absorption tube 2 73 flows to the interior of the water supply pipe 2 74. The heat inside the battery pack 2 is taken away by the circulation of the coolant inside the heat absorption tube 1 72, the heat absorption tube 2 73 and the water supply pipe 2 74, thereby realizing the heat exchange and the cooling operation of the coolant. After the circulation, the coolant enters the interior of the return pipe 75, and flows back to the interior of the water storage chamber 51 through the water supply pipe 3 76. When the coolant flows back to the interior of the water supply pipe 3 76, the heat is dissipated, thereby realizing the cooling operation of the coolant circulation, thereby realizing the rapid liquid cooling operation of the battery pack 2. Embodiment 2
