Description
Technical Field
[0001] The present invention relates to a submersible, in particular to a submersible charged with energy using deep ocean currents. Background Art
[0002] The deep sea is one of the most mysterious and least fully understood areas on Earth. Studying deep-sea submersibles can help scientists explore the geological structure, biodiversity, and chemical environment of the deep sea. Studying deep-sea submersibles not only promotes the accumulation of scientific knowledge, but also promotes technological progress, provides support for resource utilization and environmental protection, and has far-reaching economic, social, and strategic significance. With the continuous breakthroughs in the maximum diving depth, a new problem arises: how to stay in deep water for a longer time. If you want to build an experimental platform in the deep sea, then this problem cannot be avoided anyway. Among them, the continuous supply of energy is one of the obstacles to solving this problem.
[0003] In the deep sea, the ocean current energy is relatively abundant, but other available energy sources are very scarce. Although the ocean current energy reserves are rich, the current velocity in the deep sea is generally low. The underwater turbine technology that uses ocean currents to generate electricity requires a large current velocity, so it is not suitable for installation on deep-sea manned submersibles to generate electricity. Existing submersibles do not have devices that can efficiently use low-speed deep-sea currents to charge energy. Summary of the invention
[0004] Purpose of the invention: The purpose of the present invention is to provide a submersible that can utilize low-speed ocean currents to charge its energy and utilize deep-sea currents to charge its energy.
[0005] Technical solution: The submersible for charging energy using deep ocean currents described in the present invention includes a hull, on which are disposed a plurality of power generation devices, the power generation devices comprising an elongated vibrator and a coil disposed on the hull; the vibrator is connected to a movable magnet, which is slidably connected in the coil; when generating electricity, the submersible adjusts the direction of the hull so that the angle between the ocean current direction and the axis of the vibrator is in the range of (0°, 180°), and the ocean current drives the vibrator to vibrate, driving the movable magnet to move back and forth in the coil.
[0006] Based on the above technical solution, the power generation device includes a long vibrator. When generating electricity, the direction of the hull is adjusted so that the direction of the ocean current is not parallel to the axis of the vibrator. In this way, when the ocean current flows through the surface of the vibrator, based on the principle of flow-induced vibration, the vibrator will vibrate back and forth in a direction perpendicular to the plane formed by its axis and the direction of the ocean current. The vibrator is connected to a moving magnet that is slidably connected to the coil. The reciprocating vibration of the vibrator will drive the moving magnet to move back and forth in the coil, thereby causing the coil to passively cut the magnetic lines of force to generate electricity. Flow-induced vibration can occur under low flow conditions. Therefore, the power generation device designed based on this principle can use low-speed ocean currents to generate electricity and then charge the submersible.
[0007] Preferably, the vibrator is cylindrical; when generating electricity, the submersible adjusts the direction of the hull so that the direction of the ocean current is perpendicular to the axis of the vibrator.
[0008] Compared with vibrators of other shapes, cylindrical vibrators can induce flow-induced vibrations more stably and efficiently under low flow conditions, so setting the shape of the vibrator to a cylindrical shape can improve the power generation efficiency of the power generation device in the deep sea; the direction of the ocean current perpendicular to the axis of the vibrator can more effectively drive the vibrator to vibrate, thereby improving the power generation efficiency.
[0009] Preferably, the movable magnet translates along the axial direction of the coil.
[0010] The movable magnet moves along the axial direction of the coil, and its movable distance is the farthest compared to moving in other directions, because it is slidably connected in the coil. If it moves in other directions, it will be blocked by the coil after moving a certain distance. The maximum movable distance in this direction can enable the coil to cut the magnetic flux lines more effectively.
[0011] Preferably, the vibrator is provided with a connecting rod, and the moving magnet is mounted on the connecting rod.
[0012] Preferably, the axes of the vibrator and the connecting rod are perpendicular to each other.
[0013] Based on the principle of flow-induced vibration, the vibration direction of the vibrator will be perpendicular to its axis. The axes of the vibrator and the connecting rod are perpendicular to each other, and the vibration direction of the vibrator is parallel to the axis of the connecting rod. This can better drive the moving magnet to slide in the coil. If the axes of the vibrator and the connecting rod are not perpendicular, when the vibrator vibrates, the connecting rod will move in other directions besides the axial direction, which will be hindered and reduce the power generation efficiency.
[0014] Preferably, the power generation device comprises a resetting device for restoring the vibrator to an initial position.
[0015] Setting a reset device can restore the vibrator to its initial position after power generation is completed, and can prevent the vibrator from moving too much and causing the magnet to slip out of the coil. At the same time, compared with a simple limiting device, the reset device can also prevent the moving magnet from abutting against the limiting device at one end of the coil. If this happens, the moving magnet will be blocked when moving in the direction of the limiting device, limiting the movement of the moving magnet and reducing the power generation efficiency.
[0016] Preferably, the power generation device is arranged in multiple numbers forward and backward along the ocean current during power generation, the initial position of the rear vibrator is located within the tail vortex range of the front vibrator, and the length of the connecting rod is adjustable.
[0017] Multiple power generation devices are arranged forward and backward along the ocean current during power generation, and the initial position of the rear vibrator is located within the tail vortex range of the previous vibrator. In this way, the tail vortex of the previous vibrator can also improve the vibration of the rear vibrator compared to the ordinary ocean current. Such arrangement of multiple power generation devices can improve the overall power generation efficiency; the adjustable length of the connecting rod can flexibly adjust the vibrator position according to different situations to ensure that the initial position of the rear vibrator is located within the tail vortex range of the previous vibrator.
[0018] Preferably, the resetting device is two fixed magnets arranged on both sides of the moving magnet in the axial direction, and the magnetic poles of the fixed magnet on each side are the same as those on the opposite side of the moving magnet.
[0019] The reset device uses two fixed magnets to keep the movable magnet at a fixed position between the two fixed magnets through magnetic force when no external force is applied. The reset device has a simple structure and is easy to set up.
[0020] Preferably, a beam shell is provided on the hull, the power generation device is arranged in the beam shell, and the outlet size of the beam shell is smaller than the inlet size.
[0021] The outlet size of the beam shell is smaller than the inlet size, so the velocity of the ocean current flowing through the beam shell will increase, and the power generation device is arranged in the beam shell, which can increase the vibration of the oscillator and improve the power generation efficiency.
[0022] Preferably, a propeller is provided at the rear of the hull, and the outlet of the beam shell wraps around the propeller so that the propeller draws seawater from the beam shell.
[0023] The propeller pushes the submersible forward by sucking seawater from the front of the hull and then spraying it backwards, and the beam shell outlet wraps the propeller inside, so that the propeller can only suck seawater from the beam shell, further accelerating the flow rate of seawater in the beam shell, thereby improving power generation efficiency.
[0024] Beneficial effects: Compared with the prior art, the present invention has the following significant effects: by arranging a coil on the hull, a movable magnet is slidably connected inside the coil, the movable magnet is connected to a long strip vibrator, and the direction of the hull is adjusted during power generation so that the direction of the ocean current is not parallel to the direction of the vibrator axis. Based on the principle of flow-induced vibration, the low-velocity ocean current can be used to make the vibrator drive the movable magnet to move back and forth in the coil to achieve effective power generation.

DETAILED DESCRIPTION
[0026] As shown in the figure, a submersible for charging energy using deep ocean currents described in the present invention includes a hull 1, on which are disposed a plurality of power generation devices 2, the power generation devices 2 including a long vibrator 3 and a coil 4 disposed on the hull 1; the vibrator 3 is connected to a movable magnet 5, which is slidably connected in the coil 4; when generating electricity, the submersible adjusts the direction of the hull so that the angle between the current flow direction and the axis of the vibrator 3 is in the range of (0°, 180°), and the ocean current drives the vibrator 3 to vibrate, driving the movable magnet 5 to move back and forth in the coil 4.
[0027] The power generation device 2 includes a long vibrator 3, a coil 4 and a movable magnet 5. The vibrator 3 can be cylindrical, triangular prism or other long strips. The present embodiment adopts a cylindrical shape. The vibrator 3 is connected to the movable magnet 5 through a connecting rod 6. The axis of the vibrator 3 and the connecting rod 6 can be at any angle. In the present embodiment, the vibrator 3 is perpendicular to the axis of the connecting rod 6. The movable magnet 5 in the present embodiment adopts a ring magnet. Of course, magnets of other shapes can also be used as long as they are connected to the connecting rod 6. The movable magnet 5 is slidably connected to the coil 4. Specifically, a supporting shell 9 can be set in the coil 4, and the coil 4 is mounted therein. Outside the supporting shell 9, the movable magnet 5 is slidably connected inside the supporting shell 9, and the supporting shell 9 is connected to the outer wall of the hull 1; the coil 4, the movable magnet 5, the connecting rod 6 and the supporting shell 9 are coaxially arranged, so that the movable magnet 5 can translate along the axial direction of the coil 4; of course, the movable magnet 5 can also translate along the axis of the coil 4, for example, the axis of the connecting rod 6 is perpendicular to the axis of the coil 4, and the coil 4 bypasses the connecting rod 6 when winding. A through hole matching the connecting rod 6 is provided on the supporting shell 9, and the connecting rod 6 can move with the movable magnet 5 in a direction perpendicular to the axis of the coil 4, but the moving distance is small, which is not conducive to power generation.
[0028] The power generation device 2 is also provided with a reset device for restoring the movable magnet 5 (that is, the vibrator 3) to its initial position. In this embodiment, the reset device uses two fixed magnets 7 disposed on both sides of the movable magnet 5. The magnetic poles of the fixed magnets 7 and the opposite sides of the movable magnet 5 are the same, so that the movable magnet 5 will be repelled when it approaches any of the fixed magnets 7, so that it will remain in a balanced position between the two fixed magnets 7 when there is no external force. In addition to using two fixed magnets 7, the reset device can also use an elastic mechanism such as a spring. For example, the two ends of the spring are respectively connected to the outer wall of the hull 1 and the movable magnet 5, which can also restore the movable magnet 5 to its initial position.
[0029] The power generation device 2 can be provided in multiple numbers, and they are arranged front and back along the flow direction of the ocean current during power generation, and the initial position of the rear vibrator 3 is located in the vortex range of the tail of the previous vibrator 3, because the ocean current will form a vortex at its tail (that is, the end facing away from the ocean current) after flowing through the surface of the vibrator 3, and the vortex will enhance the vibration of the vibrator 3. Such an arrangement can improve the power generation efficiency; the length of the connecting rod 6 is adjustable, for example, a conventional electric telescopic rod is used, so that the vortex range of the tail of the previous vibrator 3 can be determined according to the relative direction of the ocean current flow direction and the vibrator 3 during power generation and the ocean current flow rate, and then the initial position of the rear vibrator 3 is adjusted accordingly to meet the above conditions; of course, the length of the connecting rod 6 can also be fixed, but this requires first pre-setting the relative direction of the ocean current flow direction and the vibrator 3 during power generation and the minimum flow rate of the ocean current, and then calculating the range of the vortex of the tail of the previous vibrator 3, and setting the initial position of the rear vibrator 3 within this range. When generating electricity, the vibrator 3 can be driven to vibrate as long as the flow direction of the ocean current is not parallel to the axis of the vibrator 3. When the flow direction of the ocean current is perpendicular to the axis of the vibrator 3, the vibration effect of the vibrator 3 is best.
[0030] like Figure 4 As shown, the energy capture efficiency of setting up one power generation device 2 and setting up two power generation devices 2 according to the above requirements is demonstrated. A single oscillator corresponds to one power generation device 2, and oscillator A and oscillator B are respectively the front oscillator 3 and the rear oscillator 3 along the direction of the ocean current when two power generation devices 2 are set up; as can be seen from the figure, in the case of a single oscillator, its energy capture efficiency is slightly higher than that of oscillator A under certain low flow conditions, but the energy capture efficiency of a single oscillator is lower than that of oscillator B, and the overall energy capture efficiency is not as good as the total energy capture efficiency of oscillator A and oscillator B. The energy capture efficiency is high, and the power generation efficiency is naturally high. Therefore, setting up multiple power generation devices 2 according to the above requirements can improve the power generation efficiency.
[0031] The hull 1 is provided with a beam shell 8, and the power generation device 2 is arranged in the beam shell 8. The outlet size of the beam shell 8 is smaller than the inlet size. The beam shell 8 can adopt a streamlined structure with the size gradually decreasing from the inlet to the outlet. The beam shell 8 can be arranged on the left and right sides of the tail of the hull 1, or in other directions such as the top and the bottom, or only one beam shell 8 can be arranged; a propeller is also provided at the tail of the hull 1, and the outlet of the beam shell 8 extends backward to wrap the propeller inside, so that the propeller can only extract seawater in the beam shell 8. Because the propeller is a conventional device, it is not shown in the accompanying drawings; a water spray guide device matching the propeller can also be provided to guide the water flow sprayed by the propeller to cooperate with the rudder to better realize the guidance of the submersible.
