Description

Technical Field

[0001] The present invention relates to the technical field of ship supervision and rescue, and in particular to a wireless charging ship supervision terminal. Background Art

[0002] At present, there are usually two ways to power a ship monitoring terminal: ordinary dry cell batteries and rechargeable batteries. Among them, ordinary dry cell batteries are directly installed in the buoy of the ship monitoring terminal. The buoy has no electrical connection with the outside world, which is safe and reliable. However, the power consumption of the ship monitoring terminal is relatively large, and it needs to operate stably and continuously for a long time. Therefore, a large number of dry cell batteries are required in the buoy, which is large in size and heavy in weight, and it is difficult to meet the miniaturization design requirements of small ship monitoring and rescue. Rechargeable batteries can be charged from the outside world, meeting the requirements of the miniaturization design of existing ship monitoring terminals. However, the buoy needs to be electrically connected to the outside world through contacts or slip rings, and the rechargeable battery is charged by the ship's power supply to achieve continuous and stable operation of the ship monitoring terminal. The ship monitoring terminal is usually installed on the deck or railing. The marine environment in which it is located can easily cause corrosion of the electrical connection structure of the contacts or slip rings, affecting the charging efficiency, requiring high maintenance costs, and also resulting in a reduction in the service life of the ship monitoring terminal. Summary of the Invention

[0003] The present invention aims to provide a wireless charging ship monitoring terminal to solve the technical problem in the prior art that the electrical connection method used for charging the ship monitoring terminal is easily corroded.

[0004] The present invention provides the following basic scheme:

[0005] A wireless charging ship supervision terminal includes a base and a buoy. The base is provided with a limiting ring with one end open, the bottom of the limiting ring is provided with a charging protrusion, the bottom of the buoy is provided with a charging groove matching the shape of the charging protrusion, a transmitting end coil is provided in the charging protrusion, and the buoy is provided with a receiving end coil used in conjunction with the transmitting end coil.

[0006] Beneficial effects of the basic program:

[0007] The setting of the limiting ring limits and guides the buoy when installing the buoy. The shapes of the charging protrusion and the charging groove match each other. When installing the buoy, the shapes of the charging protrusion and the charging groove allow both to be quickly positioned and installed. The transmitting coil and the receiving coil are used in conjunction with each other. The transmitting coil is set in the charging protrusion, and the corresponding receiving coil is set in the position corresponding to the charging groove in the buoy. The transmitting coil and the receiving coil are wireless charging coils. The transmitting coil uses the principle of electromagnetic induction to enable the receiving coil to receive electrical energy, thereby realizing wireless charging of the buoy. Wireless charging eliminates the need for exposed contacts and slip rings, thereby avoiding corrosion caused by charging methods exposed in the marine environment and extending the service life of the ship monitoring terminal.

[0008] Furthermore, a strip groove is provided at the bottom of the buoy, one end of which is connected to the peripheral wall of the buoy, and a mounting plate is provided at the bottom of the buoy to cover the other end of the strip groove; a locking plate is provided in the base, one end of the locking plate is provided with an elastic part, and the other end can extend along the strip groove into the end of the strip groove covered by the mounting plate, and a guide part is provided at the end of the locking plate away from the elastic part, and a notch is provided at the bottom of the guide part.

[0009] Beneficial effect: One end of the strip groove is blocked by the mounting plate, forming a space with the groove direction of the strip groove as the opening. An elastic member is provided at one end of the locking plate. In the initial state, the elastic member is free to stretch. At this time, the other end of the locking plate is located in the limiting ring, and this end is located below the space. When installing the buoy, the buoy moves down along the limiting ring, and the mounting plate contacts and applies a force to the guide portion of the locking plate. Guided by the guide portion, the locking plate moves into the base. At this time, the elastic member is compressed. When the mounting plate moves down to the notch, the force on the guide portion of the locking plate disappears. Under the force of the elastic member's reset, the locking plate moves toward the buoy, so that the mounting plate and the notch are offset. At this time, the guide portion of the locking plate is located in the space, and the locking plate locks the buoy, completing the assembly of the ship monitoring terminal.

[0010] Furthermore, the side of the guide portion facing the buoy is an inclined surface, and the inner angle between the inclined surface and the top surface of the notch is an acute angle.

[0011] Beneficial effect: The setting of the inclined surface makes it easier to disperse the force during the downward movement of the buoy, making it less likely to slip and achieving rapid locking of the buoy.

[0012] Furthermore, a guide block is provided at the bottom of the limiting ring, and a guide hole is opened along the groove direction of the strip groove at one end of the locking plate away from the elastic member, and the guide block is slidably connected to the guide hole.

[0013] Beneficial effect: The setting of the guide hole allows the locking plate to be guided and limited during its movement.

[0014] Furthermore, a lever is provided in the base, one end of the lever is against the end of the locking plate away from the buoy, and the other end is provided with a reset groove, the bottom of the reset groove is connected to a reset member, and the reset member and the locking plate are located on the same side of the lever.

[0015] Beneficial effects: One end of the lever is used to drive the locking plate to move away from one end of the buoy toward the base. The setting of the reset groove facilitates the installation and connection of the reset part. The setting of the reset part works together with the elastic part to move the locking plate, thereby realizing rapid reset of the locking plate.

[0016] Furthermore, a releaser and a lever are provided in the base. One end of the lever is used to drive the locking plate to move away from one end of the buoy toward the base, and the other end is against the releaser. The releaser and the locking plate are respectively located on both sides of the lever.

[0017] Beneficial effect: The releaser is triggered in an abnormal situation, such as a shipwreck. The releaser is set to push the lever when triggered, causing the other end of the lever to move in the opposite direction, thereby driving the locking plate to move backward, so that the buoy is no longer locked. At this time, the buoy can break away from the base and float to the sea surface to send an alarm message and seek ship rescue.

[0018] Furthermore, an annular groove is provided at the bottom of the buoy, and an elastic separator is provided at the bottom of the limiting ring. The axial direction of the elastic separator is parallel to the axial direction of the annular groove, and one end of the elastic separator away from the bottom of the limiting ring is against the bottom of the annular groove.

[0019] Beneficial Effects: The annular groove provides space for the elastic separator and facilitates the application of force to it. Initially, the elastic separator is in a freely stretched state. When the buoy is installed, the elastic separator is compressed. When the buoy is no longer locked, the elastic separator returns to its original position, applying force to the buoy, quickly separating the buoy from the base and assisting the buoy in quickly rising to the surface.

[0020] Furthermore, a hoop is provided on the base.

[0021] Beneficial effect: The setting of the clamp is used to fix the ship monitoring terminal on the deck or railing to achieve ship monitoring and rescue.

[0022] Furthermore, a solar panel is provided on the top of the base.

[0023] Beneficial effect: The setting of solar panels can provide power when the ship's power supply is unable to supply power, thereby ensuring the continuous and stable operation of the ship supervision terminal.

[0024] Furthermore, the top of the buoy extends outward to form a rain shield, and the top of the limiting ring is located inside the rain shield.

[0025] Beneficial effect: The rain shield blocks the top of the limit ring, preventing falling rainwater from entering the limit ring when it rains on the sea, further reducing the impact of the marine environment on the electrical connection between the buoy and the base in the ship monitoring terminal.

[0035] Example 1

[0036] A wireless charging ship monitoring terminal, as shown in the attached Figure 1 As shown, it includes a base 1 and a buoy 2, as shown in the attached Figure 2As shown, a charging groove 3 is provided at the bottom of the buoy 2, and a transmitting coil is provided inside the buoy 2, with the transmitting coil facing the charging groove 3. A strip groove 4 is also provided at the bottom of the buoy 2, one end of which is connected to the peripheral wall of the buoy 2, and a mounting plate 5 is provided at the bottom of the buoy 2 to cover the other end of the strip groove 4. In this embodiment, the mounting plate 5 is fixed to the bottom of the buoy 2 by screws. An annular groove 6 is also provided at the bottom of the buoy 2, and the annular groove 6 and the buoy 2 are coaxial. In this embodiment, there are two strip grooves 4, and the two strip grooves 4 are parallel and located on both sides of the annular groove 6. The top of the buoy 2 extends outward to form a rain shield 7.

[0037] As attached Figure 3 As shown, a limiting ring 8 with one end open is provided on the base 1, and the top of the limiting ring 8 is located inside the rain shield 7. A charging protrusion 9 matching the shape of the charging groove 3 is provided at the bottom of the limiting ring 8, and a transmitting coil used in conjunction with the receiving coil is provided in the charging protrusion 9. The transmitting coil and the receiving coil are coils used for existing wireless charging. An elastic separator 10 is provided at the bottom of the limiting ring 8. The axial direction of the elastic separator 10 is parallel to the axial direction of the annular groove 6. The end of the elastic separator 10 away from the bottom of the limiting ring 8 is against the bottom of the annular groove 6. In the initial state, the elastic separator 10 is free to stretch. When the buoy 2 is assembled with the base 1, the elastic separator 10 is compressed. In this embodiment, the elastic separator 10 is a spring, and the spring is bonded to the bottom of the limiting ring 8.

[0038] As attached Figure 4 As shown, a guide block 11 is provided at the bottom of the limiting ring 8. The guide block 11 includes a connecting portion and a T-shaped portion. The free end of the T-shaped portion is fixedly connected to one side of the connecting portion. In this embodiment, the connecting portion and the bottom of the limiting ring 8 are integrally formed, and the free end of the T-shaped portion is fixedly connected to one side of the connecting portion by a screw. At this time, the longitudinal cross-sectional area on both sides of the guide block 11 is larger than the longitudinal cross-sectional area of ​​the middle portion. There are two guide blocks 11, which are respectively located in the two-shaped grooves 4.

[0039] The base 1 is provided with a locking plate 12. In this embodiment, there are two locking plates 12. Figure 5 As shown, one end of the locking plate 12 can extend from the base 1 and extend along the strip groove 4 into the end of the strip groove 4 obscured by the mounting plate 5. The end of the locking plate 12 extending from the base 1 is provided with a guide portion 13, and a notch 14 is defined at the bottom of the guide portion 13. The side of the guide portion 13 facing the buoy 2 is inclined, and the internal angle between the inclined surface and the top surface of the notch 14 is acute, that is, the inclined surface slopes from the base 1 toward the buoy 2 from top to bottom. A guide hole 15 is defined along the groove direction of the strip groove 4 at the end of the locking plate 12 extending from the base 1. The guide hole 15 is slidably connected to the guide hole 15, and the middle portion of the guide block 11 passes through the guide hole 15.

[0040] The other end of the locking plate 12 is provided with an elastic member 16. Specifically, the bottom of the end of the locking plate 12 located within the base 1 is extended to form a telescopic portion 23. The elastic member 16 is sleeved on the telescopic portion 23. In the direction of extension and contraction of the elastic member 16, the compressed length of the elastic member 16 is greater than the length of the telescopic portion 23. A limit block is also provided within the base 1. The end of the elastic member 16 away from the locking plate 12 is fixedly connected to the limit block. In this embodiment, there are two limit blocks, which are integrally formed with the base 1, and the elastic member 16 is bonded to the limit blocks.

[0041] A lever 17 is also provided in the base 1. The lever 17 includes a support rod and two lever arms 17. The two lever arms 17 are fixedly connected to the peripheral wall of the support rod, and the two lever arms 17 are located on both sides of the support rod. In this embodiment, the support rod and the lever arms 17 are integrally formed, and the two ends of the support rod are rotatably connected to the inner wall of the base 1.

[0042] One end of the lever 17 abuts against the end of the locking plate 12 facing away from the buoy 2, and is used to drive the locking plate 12 away from the buoy 2 toward the base 1. The other end defines a reset groove, the bottom of which is connected to a reset member 18. The reset member 18 and the locking plate 12 are located on the same side of the lever 17. Specifically, a release portion 22 extends from the top of the locking plate 12 away from the buoy 2. A crossbar 24 is connected between the release portions 22 of the two locking plates 12. One end of the lever 17 abuts against the side of the crossbar 24 facing the buoy 2. The other end of the lever 17 on the same side defines a reset groove, the bottom of which engages one end of the reset member 18. The end of the reset member 18 away from the lever 17 is fixedly connected to the inner wall of the base 1. In this embodiment, the locking plate 12 and the crossbar 24 are integrally formed. The reset member 18 is a spring. One end of the lever 17 is bonded to the release portion 22, and the reset member 18 is bonded to the inner wall of the base 1.

[0043] A releaser 19 is also provided within the base 1. The other end of the lever 17 abuts against the releaser 19. The releaser 19 and the locking plate 12 are located on either side of the lever 17. In this embodiment, the releaser 19 uses an existing hydrostatic pressure releaser, which includes a compressed spring. When the hydrostatic pressure releaser reaches a certain depth, the hydrostatic pressure releaser is automatically triggered, releasing the compressed spring. The end of the spring, away from the hydrostatic pressure releaser, abuts against the lever 17, pushing the lever 17 to move, causing the other end of the lever 17 to move in the opposite direction.

[0044] The base 1 is provided with a clamp 20. Specifically, a fixing slot is defined at the bottom of the base 1. One end of the clamp 20 passes through two fixing slots and exits the base 1. The other end of the clamp 20 passes through a fixture and is fixedly connected to the end that exits the base 1. In this embodiment, two fixing slots form a set, with two clamps 20 in total. The ends of the clamps 20 are fixedly connected by screws. The fixture is a ship's railing, and the clamp 20 secures the ship monitoring terminal to the railing.

[0045] A solar panel 21 is provided on the top of the base 1. In this embodiment, the solar panel 21 is embedded in the top of the base 1. When the ship's power supply is unable to power the vessel monitoring terminal, the solar panel 21 is used to power the base 1 and charge the buoy 2 through the base 1's transmitting coil and the buoy 2's receiving coil.

[0046] When assembling buoy 2, buoy 2 is pressed down along limiting ring 8, and mounting plate 5 contacts and applies force to the guide portion 13 of locking plate 12. Guided by guide portion 13, locking plate 12 moves into base 1, at which time elastic member 16 is compressed. When mounting plate 5 moves down to notch 14, the force acting on guide portion 13 of locking plate 12 disappears. Under the force of elastic member 16 returning to its original position, locking plate 12 moves toward buoy 2, causing mounting plate 5 to abut notch 14. At this time, guide portion 13 of locking plate 12 is located in strip groove 4, locking plate 12 locks buoy 2, and assembly of the vessel monitoring terminal is completed. After assembly, elastic separator 10 is in a compressed state.

[0047] When the releaser 19 is triggered, the releaser 19 pushes the lever 17 toward the buoy 2, and the other end of the lever 17 moves in the opposite direction, driving the locking plate 12 to move toward the base 1 through the cross bar 24. The guide part 13 no longer locks the safety plate, and the elastic separation part 10 resets and pushes the buoy 2, so that the buoy 2 disengages from the limiting ring 8, and the buoy 2 floats to the sea surface.

[0048] Example 2

[0049] This embodiment differs from the first embodiment in that:

[0050] There is a sub-circuit board in the base, as shown in the attached Figure 6 As shown, the sub-circuit board is equipped with a voltage filter, a voltage regulator, and a full-bridge inverter, which are electrically connected in sequence. The full-bridge inverter is electrically connected to the transmitter coil. The sub-circuit board also has a V / I sensor, as well as an electrically connected transmitter controller and a sub-microcontroller. The other output of the voltage regulator is electrically connected to the V / I sensor, the output of the V / I sensor is electrically connected to the transmitter controller, and the output of the transmitter controller is electrically connected to the voltage filter.

[0051] The voltage filter is electrically connected to the ship's power supply and the solar panels. It controls the ship's power supply. When the ship's power supply is unavailable, the solar panels switch on. A full-bridge inverter converts input DC power into AC power. The transmitter coil transmits power to the receiver coil. The transmitter control terminal adjusts the control parameters of the voltage regulator, controlling its output voltage and the electrical output parameters of the full-bridge inverter. The power supply to the transmitter coil is controlled via a sub-circuit board, enabling wireless charging of the ship's monitoring terminal.

[0052] The buoy is equipped with a main circuit board and a rechargeable battery. Figure 7 As shown, the main circuit board is provided with an electrically connected rectifier and voltage regulator, the receiving-end coil is electrically connected to the rectifier, and the voltage regulator is electrically connected to the rechargeable battery. The main circuit board also includes an electrically connected receiving-end controller and a main microcontroller, the other output end of the voltage regulator is electrically connected to the receiving-end controller, and the receiving-end controller is electrically connected to the rectifier.

[0053] The receiving coil converts the received electrical energy into alternating current (AC), while the rectifier converts the AC into direct current (DC). The receiving controller adjusts the rectifier's control parameters and controls the voltage regulator's output voltage to meet the rechargeable battery's charging parameters. The main circuit board receives power from the transmitting coil, enabling wireless charging of the rechargeable battery. The rechargeable battery ensures power supply to the buoy's internal components after the buoy detaches.

[0054] In this embodiment, the sub-microcontroller and the main microcontroller use a chip model PIC16F1947, and the sub-circuit board, the transmitting end coil, the main circuit board and the receiving end coil are all provided with a sealing layer. Specifically, the sub-circuit board, the transmitting end coil, the main circuit board and the receiving end coil are encapsulated with sealant to further reduce the impact of the marine environment on the devices in the ship monitoring terminal.

[0055] Example 4

[0056] The difference between this embodiment and the second embodiment is that:

[0057] A wireless charging ship monitoring terminal is also equipped with a communication module, a posture detection module, a temperature detection module, a GPS positioning module, and a water pressure detection module. The communication module, posture detection module, temperature detection module, GPS positioning module, and water pressure detection module are all electrically connected to a main microcontroller. The communication module uses a dual-mode communication method using NB-IoT and BeiDou-3 short messages. Within the NB-IoT signal coverage area, it communicates with the remote control center using NB-IoT. Outside the NB-IoT signal coverage area, it communicates with the remote control center using BeiDou-3 short messages, achieving full ocean coverage.

[0058] The attitude detection module monitors the vessel's tilt, the temperature detection module collects current temperature information, the GPS positioning module collects real-time GPS location information, and the water pressure detection module acquires current water pressure information. During normal operation, the main microcontroller acquires the vessel's tilt, temperature, GPS location, and water pressure information, controls the communication module to transmit these information in real time, and uses water pressure information to determine whether the preset water pressure has been reached. Real-time reporting of the vessel's dynamic information allows the vessel's current status to be monitored, and water pressure information can be used to determine whether the vessel is in danger of sinking.

[0059] In the event of a shipwreck, the water pressure reaches a preset pressure when the ship sinks to a certain depth. The main microcontroller is also responsible for sending a trigger signal to the release mechanism when the water pressure reaches the preset pressure. This triggers the release mechanism, causing the buoy to detach from its base and float to the surface. The main microcontroller also controls the communication module to send an alarm signal when the water pressure reaches the preset pressure. This alarm signal notifies the ship of the sinking accident, enabling timely rescue efforts.

[0060] The above is only an embodiment of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the field are aware of all common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the field can improve and implement this scheme in combination with their own abilities under the inspiration given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
