Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Before providing a further detailed description of the embodiments of the present invention, the directional terms used in the embodiments of the present invention, such as "upper part," "lower part," and "side part," are used to refer to... Figure 1 The orientation shown is a reference and does not limit the scope of protection of this invention.

[0021] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 16As shown, this application provides a deep-sea ocean current energy power supply base, including: a shell, two shells are provided, the two shells are connected to form a receiving cavity, and a power supply main body is provided inside the receiving cavity; a triggering device 4 is provided on the shell, when the triggering device 4 is triggered, the two shells separate and fall off, the power supply main body changes from a retracted state to an extended state, and the power supply main body converts ocean current energy into electrical energy. Figure 3 As shown, the outer casing includes a tail casing 1, a middle casing 2, and a front casing 3. The front casing 3 and the tail casing 1 are connected via the middle casing 2. The two casings are symmetrically arranged, and when they are closed together, they form a receiving cavity. The two casings are connected by a connecting structure. When the triggering device 4 is triggered, the connecting structure between the casings is broken, and the two casings separate and detach. Figure 14 and Figure 15 As shown. After the two outer shells separate and detach, the force exerted by the outer shells on the power supply body disappears, and the power supply body changes from a retracted state to an extended state, as shown. Figure 16 As shown, the extended power supply unit converts ocean current energy into electrical energy to power deep-sea observation equipment. The power supply base station of this application has a simple structure and small footprint, and deployment often only requires a short-term docking of the engineering vessel, greatly reducing the cost of deploying in-situ deep-sea power supply equipment.

[0023] In one embodiment, such as Figure 2 , Figure 4 and Figure 11 As shown, the triggering device 4 includes a striker slider 4-1, a column 4-2, a pawl 4-3, a weight 4-5, and a connector 4-6. One end of the connector 4-6 is connected to the weight 4-5, and the other end is connected to the outer casing. The pawl 4-3 is mounted on the striker slider 4-1, and the weight 4-5 is located within the pawl 4-3. One end of the column 4-2 abuts against the weight 4-5, and a fixing rod 4-4 is mounted on the column 4-2, which is connected to the pawl 4-3. The striker slider 4-1 and the outer casing are interference-fitted. Specifically, the lower part of the striker slider 4-1 is the striker, and the upper part is a hollow structure. The lower part of the column 4-2 is located within the hollow structure of the striker slider 4-1. To avoid hindering the movement of the striker slider 4-1, the lower part of the column 4-2 only occupies a portion of the hollow structure. The upper end of column 4-2 abuts against the lower surface of weight 4-5. A fixing rod 4-4 is provided on the outer periphery of column 4-2, which connects to the claw 4-3, thus fixing the claw 4-3 and preventing it from coming apart. The outer periphery of the hollow structure is interference-fitted with the outer shell, and the connecting piece 4-6 is a steel rope, which connects to the middle outer shell 2. The claw 4-3 is connected to the outer edge of the hollow structure. The claw 4-3 includes a connecting rod and a buckle. One end of the connecting rod is rotatably connected to the hollow structure, and the other end is rotatably connected to the buckle. The fixing rod 4-4 is connected to the buckle.

[0024] Specifically, when not triggered, the latch locks the weight 4-5, which is connected to the two central outer shells 2 via the connector 4-6. The two outer shells are connected by a pin. At this time, the connector 4-6 is taut, and the entire structure of the triggering device 4 is locked. When the striker slider 4-1 is impacted, it moves upward after the impact, breaking the connection between the striker slider 4-1 and the outer shell. As the striker slider 4-1 moves upward, the connection between the pawl 4-3 and the fixing rod 4-4 breaks. The pawl 4-3 opens under the action of the striker slider 4-1, releasing the weight 4-5. The connector 4-6 loosens and moves upward, breaking the connection between the connector 4-6 and the outer shell. The connection between the two outer shells breaks, and the two outer shells separate and fall off.

[0025] In another implementation, such as Figure 12 , Figure 15 As shown, the triggering device 4 includes a sealed chamber 4a, a delay controller, and a magnetic structure. The delay controller is housed within the sealed chamber 4a and is electrically connected to the magnetic structure. The two outer shells are connected via the magnetic structure. The delay controller includes a timer device 4b, a control board 4c, and a delay triggering device battery pack 4f. The sealed chamber 4a is equipped with sealing bolts 4d and a waterproof connector 4e. The sealed chamber 4a is sealed using the sealing bolts 4d and supplies power and transmits signals to the outside via the waterproof connector 4e. The timer device 4b, control board 4c, and delay triggering device battery pack 4f are installed in the sealed chamber 4a. By controlling the timer device 4b to set the timing, after the corresponding time count is completed, the timer device 4b sends a signal to the control board 4c. The control board 4c disconnects the power supply circuit of the magnetic structure at the outer shell connection, preventing the delay triggering device battery pack 4f from supplying power to the magnetic structure via the waterproof connector 4e, thus causing the two outer shells to separate and detach.

[0026] Specifically, such as Figure 4 , Figure 7 and Figure 10 As shown, the main power supply unit includes a turbine unit 5, a power generation unit 6, an energy storage compartment 7, and an energy storage device 8. The power generation unit 6 includes a permanent magnet pole group 6-1 and a coil group 6-2. The turbine unit 5 and the energy storage compartment 7 are rotatably connected. The permanent magnet pole group 6-1 is installed on the turbine unit 5, and the coil group 6-2 is installed in the energy storage compartment 7. The permanent magnet pole group 6-1 and the coil group 6-2 are coaxially opposite each other. The energy storage device 8 is installed in the energy storage compartment 7, and the coil group 6-2 and the energy storage device 8 are electrically connected.

[0027] Furthermore, the permanent magnet pole assembly 6-1 includes multiple magnetic poles, which are uniformly arranged circumferentially around the axis of the energy storage chamber 7. The coil assembly 6-2 includes multiple coils, which are uniformly arranged circumferentially around the axis of the energy storage chamber 7. The permanent magnet pole assembly 6-1 is mounted on the turbine unit 5 and rotates with it. The coil assembly 6-2 is located in the energy storage chamber 7. During rotation, the permanent magnet pole assembly 6-1 generates an alternating magnetic field. Under the influence of the alternating magnetic field, the coil assembly 6-2 generates current. The permanent magnet pole assembly 6-1 and the coil assembly 6-2 are separately arranged. Due to the large radius of the turbine unit 5 and the energy storage chamber 7, they can accommodate more magnetic poles and coils, thus achieving high efficiency even at low speeds. Simultaneously, since the permanent magnet pole assembly 6-1 is located outside the energy storage chamber 7 and the coil assembly 6-2 is located inside, there is no contact between them. Therefore, no dynamic sealing device is needed, reducing the overall leakage risk of the system and significantly increasing the system's pressure resistance depth and service life.

[0028] Specifically, in another embodiment, the power generation device 6 may also include a magnetic coupling and an integrated permanent magnet generator to convert mechanical energy into electrical energy.

[0029] Specifically, such as Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, the energy storage compartment 7 is equipped with a power supply interface, which is electrically connected to the energy storage device 8. Further, the energy storage device 8 is a battery pack. The power supply interface includes a wired power supply interface 10 and a wireless power supply interface 11. Under the influence of ocean currents, the turbine unit 5 drives the permanent magnet pole assembly 6-1 to rotate, thereby generating an alternating magnetic field, which in turn generates current in the coil assembly 6-2. The generated electrical energy is transferred to the battery pack via wires 9 and stored as chemical energy. The wired power supply interface 10 and the wireless power supply interface 11 are connected to the battery pack via wires 9, and the battery pack supplies power to the wired power supply interface 10 and the wireless power supply interface 11. Various sensors can be installed on the wired power supply interface 10 to acquire hydrological information. The wireless power supply interface 11 can provide energy for the periodic cruising of the unmanned underwater vehicle. It should be noted that wire 9 does not refer to a specific wire, but rather to this type of wire.

[0030] like Figure 15 and Figure 16 As shown, the power supply base station also includes a signal transmission line 12 and a satellite communication module 13, through which data is received and uploaded. In another embodiment, the unmanned underwater vehicle can carry the satellite communication module 13 to surface, thereby completing information exchange.

[0031] Specifically, such as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the turbine assembly 5 includes a main rod 5-1, a first scissor lift 5-2, a first slider 5-3, a second slider 5-4, and blades. The first end of the main rod 5-1 is connected to the energy storage compartment 7 via a bearing. The first slider 5-3 and the second slider 5-4 are sleeved on the main rod 5-1 and connected by a first elastic element. Under the elastic force of the first elastic element, the first slider 5-3 and the second slider 5-4 slide towards each other along the axial extension direction of the main rod 5-1. The first end of the first scissor lift 5-2 is connected to the first slider 5-3, the second end of the first scissor lift 5-2 is connected to the second slider 5-4, and the third end of the first scissor lift 5-2 is connected to the blades. Furthermore, the blade includes a first blade 5-5, a second blade 5-10, and a third blade 5-11. The second blade 5-10 is disposed at the first end of the first blade 5-5, and the second blade 5-10 and the first blade 5-5 are connected by a first transmission structure 5-12. The third blade 5-11 is disposed at the second end of the first blade 5-5, and the third blade 5-11 and the first blade 5-5 are connected by a second transmission structure 5-13. The third end of the first scissor link 5-2 is connected to the first blade 5-5.

[0032] Furthermore, the first elastic element is a tension spring, and the main rod 5-1 is provided with a guide groove extending along the axis of the main rod 5-1. The first slider 5-3 and the second slider 5-4 are both slidably connected to the guide groove, and the first slider 5-3 and the second slider 5-4 are connected by the first elastic element. When the triggering device 4 is not triggered, the two outer shells are not separated and detached. The force exerted by the two outer shells on the first scissor link 5-2 is greater than the force exerted by the first elastic element on the first scissor link 5-2. The first slider 5-3 and the second slider 5-4 are spaced apart, the first elastic element is in a stretched state, and the first scissor link 5-2 is in a retracted state. When the triggering device 4 is triggered, the two outer shells separate and detach, the force exerted by the two outer shells on the first scissor link 5-2 disappears, and the force exerted by the first elastic element on the first scissor link 5-2 causes the first slider 5-3 and the second slider 5-4 to move closer together. The first scissor link 5-2 changes from a retracted state to an extended state.

[0033] Furthermore, a fixing plate is provided on the main rod 5-1, and the permanent magnet pole group 6-1 is mounted on the fixing plate. The fixing plate is a circular plate, which is sleeved on the main rod 5-1 and is interference-fitted with the main rod 5-1, such as... Figure 10 As shown, the permanent magnet pole group 6-1 is located below the fixed plate.

[0034] Furthermore, the first transmission structure 5-12 is a first gear set, of which two sets are provided, respectively located on both sides of the connection between the first blade 5-5 and the second blade 5-10. Each first gear set includes a first driving gear and a first driven gear, which are meshed and connected. The first blade 5-5 and the second blade 5-10 are connected via a first connecting shaft, which is rotatable relative to the first blade 5-5. The first connecting shaft and the second blade 5-10 are fixedly connected. Two first driven gears are respectively located at both ends of the first connecting shaft, and two first driving gears are respectively fixed at both ends of the second connecting shaft. The second connecting shaft and the first blade 5-5 are rotatably connected. The second connecting shaft drives the first driving gear to rotate, which in turn drives the first driven gear to rotate, and the first driven gear drives the second blade 5-10 to rotate relative to the first blade 5-5. In this embodiment, in the retracted state (e.g....), Figure 5 (As shown) The second blade 5-10 and a portion of the first blade 5-5 are overlapped; the second blade 5-10 rotates counterclockwise relative to the first blade 5-5, and the second blade 5-10 is converted to an extended state (as shown). Figure 6 As shown in the figure, the second blade 5-10 and the first blade 5-5 are located in the same plane.

[0035] The second transmission structure 5-13 is a second gear set, of which two sets are provided, respectively located on both sides of the connection between the first blade 5-5 and the third blade 5-11. Each second gear set includes a second driving gear and a second driven gear, which are meshed and connected. The first blade 5-5 and the third blade 5-11 are connected by a third connecting shaft, which is rotatable relative to the first blade 5-5. The third connecting shaft and the third blade 5-11 are fixedly connected. Two second driven gears are respectively located at both ends of the third connecting shaft, and two second driving gears are respectively fixed at both ends of a fourth connecting shaft, which is rotatably connected to the first blade 5-5. The fourth connecting shaft drives the second driving gear to rotate, which in turn drives the second driven gear to rotate, and the second driven gear drives the third blade 5-11 to rotate relative to the first blade 5-5. In this embodiment, in the retracted state (e.g....), Figure 5 (As shown) The third blade 5-11 and a portion of the first blade 5-5 are overlapped; the third blade 5-11 rotates clockwise relative to the first blade 5-5, and the third blade 5-11 is converted to an extended state (as shown). Figure 6 As shown in the figure, the third blade 5-11 and the first blade 5-5 are located in the same plane.

[0036] Furthermore, the second blade 5-10 is located at the upper end of the first blade 5-5, and the third blade 5-11 is located at the lower end of the first blade 5-5.

[0037] Specifically, such as Figure 5 and Figure 6As shown, the turbine assembly 5 also includes a first drive link 5-8 and a second drive link 5-9. The first end of the first drive link 5-8 is connected to the middle joint of the first scissor link 5-2, and the second end of the first drive link 5-8 is connected to the first transmission structure 5-12, so that the first transmission structure 5-12 drives the second blade 5-10 to rotate relative to the first blade 5-5. The first end of the second drive link 5-9 is connected to the middle joint of the first scissor link 5-2, and the second end of the second drive link 5-9 is connected to the second transmission structure 5-13, so that the second transmission structure 5-13 drives the third blade 5-11 to rotate relative to the first blade 5-5.

[0038] Furthermore, the first drive link 5-8 includes a first link and a second link. The first end of the first link is rotatably connected to the middle joint of the first scissor link 5-2, and the second end of the first link is rotatably connected to the first end of the second link. The second end of the second link is fixedly connected to the middle of the second connecting shaft. When the first scissor link 5-2 extends, it pushes the first link to extend away from the main link 5-1. The first link drives the second connecting shaft to rotate through the second link, and the second connecting shaft drives the first drive wheel to rotate, thereby causing the second blade 5-10 to rotate relative to the first blade 5-5.

[0039] Furthermore, the second drive link 5-9 includes a third link and a fourth link. The first end of the third link is rotatably connected to the middle joint of the first scissor link 5-2, the second end of the third link is rotatably connected to the first end of the fourth link, and the second end of the fourth link is fixedly connected to the middle of the fourth connecting shaft. When the first scissor link 5-2 extends, it pushes the third link to extend away from the main link 5-1. The third link drives the fourth connecting shaft to rotate via the fourth link, and the fourth connecting shaft drives the second drive wheel to rotate, thereby causing the third blade 5-11 to rotate relative to the first blade 5-5.

[0040] Furthermore, such as Figure 6 , Figure 7As shown, the turbine assembly 5 also includes a second scissor lift link 5-6 and a third scissor lift link 5-7. The second scissor lift link 5-6 is located at the second end of the main rod 5-1; the third scissor lift link 5-7 is located on the main rod 5-1, near the energy storage compartment 7; a first scissor lift link 5-2 is located between the second scissor lift link 5-6 and the third scissor lift link 5-7; the second scissor lift link 5-6 is connected to the first end of the blade, the third scissor lift link 5-7 is connected to the second end of the blade, and the first scissor lift link 5-2 is connected to the middle of the blade. Further, a first slider 5-3 is located near the second scissor lift link 5-6, and a second slider 5-4 is located near the third scissor lift link 5-7. The first slider 5-3 and the second slider 5-4 slide between the second scissor lift link 5-6 and the third scissor lift link 5-7. The first scissor lift link 5-2, the second scissor lift link 5-6, and the third scissor lift link 5-7 are all connected to the first blade 5-5, enhancing the stability of the blade.

[0041] Furthermore, a main rod 5-1, a first slider 5-3, and a second slider 5-4 are provided, along with a first scissor link 5-2, a second scissor link 5-6, a third scissor link 5-7, a first drive link 5-8, a second drive link 5-9, and a blade assembly. Multiple impeller assemblies are provided, and the multiple impeller assemblies are evenly arranged around the circumference of the main rod 5-1.

[0042] Specifically, such as Figure 9 , Figure 10 As shown, the power supply main body also includes a base structure 14; the base structure 14 includes a base rod 14-1, a base slider 14-2, a base connecting rod 14-3, and a first support leg 14-4; the base rod 14-1 is connected to the energy storage compartment 7, the base slider 14-2 is sleeved on the base rod 14-1, and the base slider 14-2 and the base rod 14-1 are slidably connected; the first end of the first support leg 14-4 is rotatably connected to the energy storage compartment 7, one end of the base connecting rod 14-3 is connected to the base slider 14-2, and the other end of the base connecting rod 14-3 is connected to the first support leg 14-4.

[0043] Furthermore, when the base structure 14 is in the folded state, as Figure 2 , Figure 4 and Figure 16 As shown, when the base structure 14 is in the extended state... Figure 9 and Figure 16As shown. The base structure 14 is located at the lower part of the energy storage compartment 7. When extended, the base structure 14 abuts against the seabed to stabilize the entire power supply unit, allowing the turbine 5 to rotate under the influence of ocean current energy and convert it into electrical energy. Multiple first legs 14-4 and base connecting rods 14-3 are provided, with each base connecting rod 14-3 corresponding to a first leg 14-4. The base connecting rods 14-3 are evenly distributed circumferentially on the base slider 14-2, and the first legs 14-4 are evenly distributed circumferentially on the lower surface of the energy storage compartment 7. In the retracted state, the base slider 14-2 is close to the energy storage compartment 7. When the base structure 14 is extended, the base slider 14-2 slides downward, and the base slider 14-2, through the base connecting rods 14-3, props the first legs 14-4 away from the main base rod 5-1. After the multiple first legs 14-4 are extended, they abut against the seabed.

[0044] Furthermore, the base structure 14 also includes a second leg 14-5 and a second elastic element 14-6. The second leg 14-5 is mounted on the first leg 14-4 and is positioned away from the energy storage compartment 7. The second leg 14-5 and the first leg 14-4 are connected by the second elastic element 14-6. The elastic force of the second elastic element 14-6 is used to rotate the second leg 14-5 relative to the first leg 14-4 and abut against the seabed. The second elastic element 14-6 is a torsion spring, and the second leg 14-5 is an adaptive angle, which can adapt to the shape of the seabed, making the base structure 14 more stable.

[0045] Specifically, such as Figure 13 As shown, the blades are made of flexible thin-film material. The blades are rectangular or trapezoidal in shape. The blades are mounted on the first blade 5-5, the second blade 5-10, and the third blade 5-11, using a three-sided mounting method. One long side of the rectangle or trapezoid is a free side, which can undergo large-scale flow-induced deformation under the influence of ocean currents, exhibiting inward swinging, transitional, and outward swinging postures. When the ocean current acts on the blades, it first causes the free side of the windward blade to swing towards the center. At this time, a portion of the ocean current that would otherwise pass through the blade's resistance surface is redirected to the power surface, thus allowing the blade to obtain a greater dynamic torque under the influence of the ocean current, thereby increasing the hydrodynamic performance of the ocean current turbine. On the other hand, the free side of the blade on the leeward side swings towards the circumferential side, again obtaining a positive torque, thus further improving the efficiency of the turbine unit 5.

[0046] Specifically, such as Figure 16As shown, after the power supply base station is released from the ship or air and lands in the water, the triggering device 4 is triggered, and the outer shell separates and detaches, allowing the internal power supply unit to detach. The satellite communication module 13 is connected to the signal transmission line 12, and after the outer shell separates and detaches, the satellite communication module 13 floats to the water surface. The turbine unit 5 changes from a retracted state to an extended state, and the base structure 14 unfolds under gravity to adapt to the seabed terrain, allowing the entire unit to land stably on the seabed and begin operation.
