Description

Technical Field

[0001] The present invention relates to the field of energy technologies, and particularly to an air-sea cross-domain communication gateway with self-power supply in shallow waters. Background Art

At present, most power supplies use storage batteries, and some use solar cells as auxiliary power supplies. Therefore, it is necessary to charge regularly or replace new storage batteries. In continuous cloudy days, solar energy can hardly play a role, and the power generation efficiency is too low to generate sufficient energy for the long-term operation of the air-sea cross-domain communication gateway.

[0003] Therefore, it is necessary to provide an air-sea cross-domain communication gateway with self-power supply in shallow waters. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0040] The conversion of wave energy into electrical energy usually goes through three - stage conversion: the first - stage conversion is that the wave - receiving body absorbs wave energy; the second - stage conversion is that the intermediate conversion device optimizes the first - stage conversion to generate stable energy; the third - stage conversion is that the power - generating device converts the stable energy into electrical energy. The research on a shallow - sea self - power - supplying air - sea cross - domain communication gateway of the present invention aims to solve the technical problem of supplementing energy for the air - sea cross - domain communication gateway and provide a stable, safe and reliable power - supply solution.

[0041] A shallow - sea self - power - supplying air - sea cross - domain communication gateway of the present invention is a technology dedicated to realizing the stable endurance of air - sea cross - domain gateway communication. This technology uses the interaction between a gearbox and a rack to do work, and according to the circuit control principle, effectively converts mechanical energy into electrical energy to achieve the self - power - supply of the air - sea cross - domain communication gateway.

[0042] An air - sea cross - domain communication gateway with shallow - sea self - power - supply in an embodiment of the present application includes:

[0043] A gateway body, an anchoring device and a fixing column;

[0044] Among them, the anchoring device includes an anchor claw, an anchor crown and an anchor chain, and is used to fix the gateway body on the shallow - sea seabed.

[0045] The fixing column is connected to the top of the anchoring device, and the fixing column is slidably connected to the gateway body.

[0046] Specifically, a through - hole cooperating with the fixing column is provided at the bottom of the floating body. The first end of the fixing column is connected to the anchoring device, and the second end of the fixing column extends into the floating body and is connected to the energy conversion system; the fixing column is slidably connected to the through - hole.

[0047] Among them, the gateway body includes: an energy conversion system, an energy conversion system, a power - supply system, an electronic cabin section and a floating body.

[0048] Among them, the energy conversion system is used to convert wave energy into electrical energy.

[0049] The communication system is connected to the energy conversion system and is used to realize the information interaction between the gateway body and the outside world.

[0050] The power - supply system is connected to the energy conversion system and the communication system and is used to provide power for the gateway body.

[0052] The floating body is connected to the bottom of the electronic cabin section, used to store the energy conversion system, and used to provide buoyancy support for the gateway body and absorb wave energy to generate vertical displacement.

[0053] The self-powered air-sea cross-domain communication gateway in shallow waters of the present invention converts wave energy into mechanical energy and then into electrical energy through three-stage work for the use of the air-sea cross-domain communication gateway. The design of the floating body and the conversion mechanism of the gearbox enable the device to operate stably in harsh marine environments and output stable electrical energy. Since the wave energy density in the ocean is relatively high, a large amount of energy can be collected in a relatively small area, improving the energy conversion efficiency of the wave energy power generation device and enabling more electrical energy to be generated. Once installed, the operation and maintenance costs of the self-powered air-sea cross-domain communication gateway system in shallow waters are relatively low, and the working hours will also increase significantly.

[0054] Refer to Figure 4 , in an embodiment of the present application, the energy conversion system includes:

[0055] A slide rail, fixedly connected to the middle of the floating body, and two racks are symmetrically arranged on one side wall of the slide rail;

[0056] A housing, two through holes are symmetrically arranged on both sides of the floating body, and two shaft arms of the housing are respectively rotatably arranged on the two through holes; the housing is slidably connected to one side of the slide rail; the second end of the fixed column is connected to the bottom of the housing;

[0057] A double gear and a gearbox, both fixedly connected to the housing, a gear set is rotatably connected in the gearbox, the first gear part of the double gear meshes with the rack, and the second gear part of the double gear meshes with the gear set;

[0058] A generator, drivingly connected to the gear set, for converting mechanical energy into electrical energy.

[0059] There are eight groups of gears in the gearbox, and the rack and the gearbox are used to convert the reciprocating up and down movement of the floating body into a rotational movement. This conversion is a key step in the power generation process because the generator needs to rotate to generate electrical energy, and the anchoring device is used to stabilize the air-sea cross-domain communication gateway to better capture wave energy.

[0060] The mechanical structure part includes an electronic cabin section, a floating body, a rack, a gearbox, and an anchoring device. Among them, the floating body absorbs wave energy and floats up and down, driving the double gear to reciprocate linearly along the rack. The gearbox converts the reciprocating linear movement of the double gear along the rack into the rotational movement of the gear set, thereby generating mechanical energy. The rotor of the generator absorbs the mechanical energy and drives the rotor to rotate in the magnetic field, and then an induced electromotive force is generated in the stator coil, realizing the conversion of mechanical energy into electrical energy. The electrical energy is processed by a capacitor and a rectifier and stored in a storage battery.

[0061] In an embodiment of the present application, a communication system includes a communication device module and a main control unit module. The main control unit module realizes information interaction with the outside world through the communication device module.

[0062] The communication device module includes a Beidou communication terminal, a mobile communication terminal, a data transmission radio communication terminal, and an underwater acoustic communication terminal dry end.

[0063] In this embodiment, a shallow sea self-powered air-sea cross-domain communication gateway further includes: an underwater acoustic communication terminal wet end for realizing the conversion between electrical signals and acoustic signals; the underwater acoustic communication terminal wet end is located in seawater at a specific depth, and the underwater acoustic communication terminal wet end communicates with the underwater acoustic communication terminal dry end through a cable.

[0064] The communication forms of the underwater acoustic communication terminal dry end include: a spread spectrum mode and an orthogonal frequency division multiplexing (OFDM) mode. Both the spread spectrum mode and the orthogonal frequency division multiplexing (OFDM) mode realize corresponding signal modulation through an ARM and a DSP.

[0065] In an embodiment of the present application, the power supply system includes: a battery pack, a voltage conversion device, an STM32 single-chip microcomputer, a capacitor, a rectifier, a relay, and a backup battery pack.

[0066] The backup battery pack is connected to a generator and a gearbox, and is responsible for converting the rotational kinetic energy output by the gearbox into electrical energy, which is stored in the battery pack after being processed by the capacitor and the rectifier. Both the battery pack and the backup battery pack are used to provide electrical energy for the entire gateway. Specifically, the battery pack is responsible for providing energy supply. The battery pack outputs electrical energy to provide power support for the normal operation of other functional modules. When the energy of the battery module is exhausted, the backup battery pack can be enabled to supply power.

[0067] The voltage conversion device includes a 3.3V voltage conversion board, a 5V voltage conversion board, a 12V voltage conversion board, and a 24V voltage conversion board; the battery pack can stably output voltages of 3.3V, 5V, 12V, and 24V through the voltage conversion device.

[0068] The STM32 single-chip microcomputer is used to receive the collected power parameter information and perform processing, judgment, and decision-making; the relay is used to realize circuit switching and circuit protection. The power supply control instruction information can be downloaded into the STM32 single-chip microcomputer by writing and burning program code, and the power supply situation can be orderly controlled through the relay. At the same time, the battery pack power information can be obtained.

[0069] The working process of a shallow sea self-powered air-sea cross-domain communication gateway in an embodiment of the present application is as Figure 2 shown:

[0070] The floating body absorbs wave energy and floats up and down, driving the double gear to reciprocate linearly along the rack. The gearbox converts the reciprocating linear motion of the double gear along the rack into the rotational motion of the gear set, thereby generating mechanical energy. The rotor of the generator absorbs the mechanical energy and drives the rotor to rotate in the magnetic field, and then an induced electromotive force is generated in the stator coil, realizing the conversion of mechanical energy into electrical energy. The electrical energy is processed by the capacitor and the rectifier and then stored in the storage battery. The above process is repeated continuously, enabling the continuous conversion of wave energy and then generating electricity, greatly improving the energy utilization efficiency.

[0071] In the embodiment of the present application, the application scenario of a shallow sea self-powered air-sea cross-domain communication gateway is as Figure 3 shown:

[0072] Among them, the air-sea cross-domain communication gateway serves as the first communication terminal, the shore-based computer platform, and the underwater device serves as the second communication terminal. After installing the shallow sea self-powered air-sea cross-domain communication gateway in the shallow sea, the anchor claws bite into the soil, and the other end of the anchor chain is connected to the cross-domain communication gateway. At this time, the shallow sea self-powered air-sea cross-domain gateway system works. The floating body moves up and down with the waves, driving the double gear to reciprocate linearly along the rack. The gearbox converts the reciprocating linear motion of the double gear along the rack into the rotational motion of the gear set, generating mechanical energy. The generator converts the mechanical energy into electrical energy, which is stored in the battery pack after being processed to ensure the long-term stable operation of the air-sea cross-domain communication gateway in the shallow sea.
