Description

TECHNICAL FIELD

[0001] The present application relates to the field of power supply for water surface and underwater dual-purpose boats, in particular to a power supply system and method for water surface and underwater dual-purpose boats. BACKGROUND

[0002] In recent years, the demand for frogman carrying equipment is increasing at home and abroad, and water surface and underwater dual-purpose boats are the research focus at present.

[0003] All types of water surface and underwater dual-purpose boats have some common problems: the water surface sliding working condition is powered by a diesel engine, the underwater navigation working condition is powered by a battery, and the power source needs to be switched according to the working condition; the whole boat requires a relatively rear center of gravity when sliding on the water surface, and the center of gravity needs to be close to the center when navigating underwater. Therefore, in actual navigation, how to reasonably adjust the water surface and underwater center of gravity is one of the key technologies. SUMMARY

[0004] In view of the above-mentioned shortcomings in the prior art, the present application provides a water surface and underwater dual-purpose boat power supply system and method with a reasonable structure, which uses the battery itself as a counterweight, and the battery is pushed by a throwing mechanism and a magnet in the sliding rail, so as to adjust the position of the center of gravity of the boat body.

[0005] The technical scheme adopted by the present application is as follows:

[0006] A water surface and underwater dual-purpose boat power supply system comprises a rail, a throwing mechanism is arranged at both ends of the rail, and a battery pack is arranged to slide in the space formed by the rail and the throwing mechanism,

[0007] Cables are led out from both ends of the rail, a discharge module and a control module are connected to one end, and a charging module and a control module are connected to the other end, thereby forming a charging circuit and a discharging circuit at both ends of the rail; the battery pack has two working states of charging and discharging during sliding.

[0008] As a further improvement of the above technical scheme:

[0009] The rail comprises a sliding rail and support rails arranged on both sides of the sliding rail, and the sliding rail, the support rails and the throwing mechanism form an open sliding space.

[0010] A mounting gap is reserved between the throwing mechanism and the rail, and a watertight connector and a cable are inserted into the mounting gap.

[0011] A magnet is embedded in the side wall of the throwing mechanism close to the battery pack.

[0012] The magnet is a conventional magnet or an electromagnet.

[0013] A shielding plate is arranged between the magnet and the battery pack, and the shielding plate is movably arranged.

[0014] The application is applied to the hull and is located at the middle section of the hull.

[0015] When the hull is sliding on the water surface, the battery pack is close to the stern; when the hull is navigating under water, the battery pack is close to the center of the hull.

[0016] A power supply method using a power supply system of a water surface and underwater dual-purpose boat, comprising the following steps:

[0017] When the hull is sliding on the water surface, the battery pack is connected with the charging module, the diesel engine carried by the hull charges the battery pack, the battery pack is located at one end of the track close to the stern of the hull, the magnet at the throwing mechanism end attracts and fixes the battery pack to prevent the battery pack from moving; in this state, the center of gravity of the hull is close to the stern, and the bow is upturned.

[0018] When the hull is changed into the navigating under water state, the magnetic force of the magnet close to the stern end of the hull is eliminated, and the battery pack loses the magnetic force limiting; meanwhile, the magnetic force of the magnet close to the bow is increased, and the throwing mechanism close to the stern throws the battery pack once, so that the battery pack slides to one end of the track close to the bow and is limited by the magnet close to the bow end; at this time, the battery pack starts to discharge to the discharging module, the center of gravity of the hull is moved forward, and the function of adjusting the trim is realized.

[0019] When the hull is changed from the navigating under water state into the sliding on the water surface state, the magnet at the bow end eliminates the magnetic force, and the throwing mechanism at the bow throws the battery pack once; when the battery pack moves to the magnet at the stern end, the battery pack is attracted and limited by the magnet at the stern end; at this time, the center of gravity of the hull returns to the end close to the stern.

[0020] As a further improvement of the above technical solution:

[0021] The way of eliminating the influence of the magnet includes inserting a shielding plate between the magnet and the battery pack and disconnecting the circuit of the electromagnet.

[0022] The beneficial effects of the present application are as follows:

[0023] The present application can select the diesel engine or the battery pack as the power source according to the navigating state, the power supply can be automatically switched when the water surface navigating state and the navigating under water state are switched, and the operation is simple.

[0024] In the present application, the battery pack not only has the power supply function, but also serves as an energy storage structure and can store the energy generated by the operation of the diesel engine.

[0025] In addition, the battery pack also serves as a counterweight. Different from the conventional structure in which the counterweight needs to be additionally provided with a counterweight block, the present application concentrates the power supply switching and the center of gravity displacement into the same action of the same component, and when the battery pack slides and contacts the one end structure, the switching of the charging / discharging circuit is completed, the operation time is saved, and the operation steps are simplified.

[0026] The power source is not additionally equipped in the application, the battery pack is completely limited in the track space, there is no electromagnetic interference in use, the movement path of the electromagnetic group is stable and accurate, and there is no movement deviation in theory.

[0027] The application matches the water surface and underwater gravity center positions by moving the battery, and is realized without designing a water adjusting system, and cancels components such as water pumps and valves, thereby simplifying equipment.

[0028] The preferred mode in the application is to adopt a shielding plate to isolate the magnetic force influence, and the shielding plate has simple structure and does not affect the normal use of other components. BRIEF DESCRIPTION OF DRAWINGS

[0037] Cables are led out from both ends of the track 1, one end is connected with a discharging module 4 and a control module 5, and the other end is connected with a charging module 6 and the control module 5, thereby forming a charging circuit and a discharging circuit at both ends of the track 1; the battery pack 3 has two working states of charging and discharging in the sliding process.

[0038] The track 1 includes a sliding rail 101 and supporting rails 102 located on both sides of the sliding rail 101, and the sliding rail 101, the supporting rails 102 and the throwing mechanism 2 form an open sliding space.

[0039] The installation gap between the throwing mechanism 2 and the track 1 is reserved, and the watertight connector and the cable are inserted in the installation gap.

[0040] The magnet 7 is embedded in the side wall of the battery pack 3.

[0041] The magnet 7 is a conventional magnet 7 or an electromagnet 7.

[0042] The magnet 7 is provided with a shielding plate 8 between the magnet 7 and the battery pack 3, and the shielding plate 8 is movably arranged.

[0043] The magnet 7 is applied to the ship body 9 and located at the middle section of the ship body 9.

[0044] When the ship body 9 slides on the water surface, the battery pack 3 is close to the stern of the ship body 9; when the ship body 9 sails under the water, the battery pack 3 is close to the center of the ship body 9.

[0045] The power supply method of the power supply system for the water surface and underwater dual-purpose boat in the embodiment comprises the following steps:

[0046] When the ship body 9 slides on the water surface, the battery pack 3 is connected with the charging module 6, and the diesel engine of the ship body 9 charges the battery pack 3; at this time, the battery pack 3 is located at the end of the track 1 close to the stern of the ship body 9, the magnet 7 at the throwing mechanism 2 end attracts and fixes the battery pack 3, so as to prevent the battery pack 3 from moving; in this state, the center of gravity of the ship body 9 is close to the stern, and the bow is upturned.

[0047] When the ship body 9 changes into the underwater sailing state, the magnetic force of the magnet 7 close to the end of the stern of the ship body 9 is eliminated, and the battery pack 3 loses the magnetic force limiting; at the same time, the magnetic force of the magnet 7 close to the bow is increased, and the throwing mechanism 2 close to the stern throws the battery pack 3 once, so that the battery pack 3 slides to the end of the track 1 close to the bow and is limited by the magnet 7 close to the end of the bow; at this time, the battery pack 3 starts to discharge by connecting with the discharging module 4, the center of gravity of the ship body 9 moves forward, and the function of adjusting the trim is realized.

[0048] When the ship body 9 changes from the underwater sailing state to the water surface sliding state, the magnet 7 at the bow end eliminates the magnetic force, and the throwing mechanism 2 at the bow throws the battery pack 3 once; when the battery pack 3 moves to the magnet 7 at the end of the stern, the battery pack 3 is limited by the magnet 7 at the end of the stern; at this time, the center of gravity of the ship body 9 returns to the end close to the stern.

[0049] The way of eliminating the influence of the magnet 7 includes inserting the shielding plate 8 between the magnet 7 and the battery pack 3 and disconnecting the circuit of the electromagnet 7.

[0050] The specific structure and working principle of the application are as follows:

[0051] As Figure 1The diagram shown is a structural schematic of the power supply system of the present invention applied to a ship's hull. The power supply system is located in the middle of the hull. The battery pack 3 in the power supply system simultaneously serves as a power supply, energy storage, and counterweight. (Refer to reference...) Figure 3-a and Figure 3-b During use, the battery pack 3 has two working states: one near the bow and one near the stern.

[0052] like Figure 2 As shown, track 1 includes a slide rail 101 laid flat on the hull, and support rails 102 symmetrically arranged on both sides of the slide rail 101. The height of the support rails 102 is flush with or slightly higher than the battery pack 3. Throwing mechanisms 2 are provided at both ends of the slide rail 101. The throwing mechanisms 2, the slide rail 101, and the support rails 102 form an open space, which is similar in width to the battery pack 3, facilitating the sliding of the battery pack 3 within it.

[0053] Magnets 7 are provided on opposite surfaces of the throwing mechanism 2. Magnets 7 can be either electromagnets or ordinary magnets. A preferred embodiment of the invention uses ordinary magnets 7, which have a simpler structure and are less prone to interference. Each magnet 7 is paired with a shielding plate 8, which is inserted between the magnet 7 and the track 1. When the shielding plate 8 is inserted, the magnetic force of the magnet 7 is greatly weakened. After the shielding plate 8 is removed, the magnetic force can attract the battery pack 3.

[0054] Watertight connectors and cables are also inserted in the gap between the throwing mechanism 2 and the slide rail 101. One end of the cable at both ends of the slide rail 101 is connected to the discharge module 4 and the control module 5, and the other end is connected to the charging module 6 and the control module 5. The two ends of the slide rail 101 are respectively connected to the charging circuit and the discharge circuit. The battery pack 3 moves between the two ends of the slide rail 101 to realize the switching of charging and discharging of the battery pack 3 and the transfer of the center of gravity.

[0055] When the amphibious boat slides on the water, the bow of the hull tilts upward, and the diesel engine on the hull charges the battery pack 3. At this time, the battery pack 3 is located at the end of the slide rail 101 near the stern of the hull. The magnet 7 in the throwing mechanism 2 attracts and fixes the battery pack 3 to the end of the slide rail 101 to prevent the battery pack 3 from shaking and to ensure that the center of gravity of the entire boat is relatively far back. At the same time, the battery pack 3 is connected to the charging module 6, and the diesel engine charges the battery pack 3.

[0056] When the working condition is changed from the water surface sliding to the underwater navigation, the shielding plate 8 is inserted between the magnet 7 and the battery set 3 in the throwing mechanism 2 near the one end of the stern, the magnetic attraction of the magnet 7 to the battery set 3 is reduced, and the shielding plate 8 on the surface of the magnet 7 is removed from the throwing mechanism 2 near the other end of the bow, the magnetic attraction of the magnet 7 to the battery set 3 is increased. The battery set 3 is thrown by the throwing mechanism 2 near the one end of the stern under the weakened magnetic attraction, and is moved to the other end of the bow and is attracted by the magnet 7, at this time, the battery set 3 is connected to the discharging module 4 to start discharging, the center of gravity of the whole ship is moved forward, and the function of adjusting the pitch is realized.

[0057] When the working condition is changed from the underwater navigation to the water surface sliding, the same throwing mechanism 2 performs the operation of the other throwing mechanism 2 in the last round, that is, the magnet 7 at the one end of the bow eliminates the magnetic force, and the throwing mechanism 2 at the bow throws the battery set 3, and the battery set 3 is limited and attracted by the magnet 7 at the one end of the stern when moving to the magnet 7, at this time, the center of gravity of the ship body returns to the one end of the stern.

[0058] The application does not need to provide additional power for the movement of the counterweight, the overall structure is stable, and there is no electromagnetic interference. Only the magnetic force is used to realize the sliding and positioning, theoretically, there is no motion deviation, and the application prospect is wide.

[0059] The above description is an explanation of the application, not a limitation of the application, the scope of the application is defined in the claims, within the protection scope of the application, any form of modification can be made.
