At the same time, the power generation mechanism 8 and the first power storage component back up each other, and can supply electricity to the whole during the buoyancy process.

[0040] In the optional scheme of this embodiment, it is more preferred that a second power storage component 21 is provided in the counterweight mechanism 2, and the second power storage component 21 can be electrically connected to the power generation mechanism 8 through the connecting mechanism 3, and the second power storage component 21 can receive and store the electric energy of the power generation mechanism 8; and the second power storage component 21 can also be electrically connected to the sensing mechanism 4, the signal receiving mechanism 5, the attitude control mechanism 6 and the control component 7 through the connecting mechanism 3 and provide the required electric energy, and can provide the electric energy required by the connecting mechanism 3; by providing the second power storage component 21, the excess power generation of the power generation mechanism 8 in the standby state in the sea can be stored, and the whole power can be electrically charged in the standby state. power supply; wherein the control component 7 is connected to both the first power storage component and the second power storage component 21 to control the power supply status of the first power storage component and the second power storage component 21; the second power storage component 21 uses a low-cost waterproof lead-acid battery with long-term storage capacity, such as common 12V12AH, 12V20AH and other models, which have the characteristics of low cost, long-term storage, high deadweight and the like. If the deadweight of the second power storage component 21 meets the counterweight requirement, there is no need to set it as other counterweight blocks.

[0041] In the optional scheme of this embodiment, it is more preferred that the connecting mechanism 3 is connected to the power generation mechanism 8, and the connection points of the connecting mechanism 3 and the counterweight mechanism 2 are provided with connection contacts. When the connecting mechanism 3 is connected to the counterweight mechanism 2, the connection contacts are electrically conductive to make the power generation mechanism 8 electrically conductive with the second power storage component 21; specifically, the connecting mechanism 3 is configured as a connecting rod as a whole, the upper end of the connecting rod is fixedly connected to the shell of the lower end of the power generation mechanism 8, and the lower end of the connecting rod is detachably connected to the counterweight mechanism 2.

At the same time, in order to meet the buoyancy speed requirements during the buoyancy process, a streamlined design is adopted to reduce drag, and corresponding installation holes for the sensing mechanism 4, the signal receiving mechanism 5, and the attitude control mechanism 6 are reserved. In addition, the buoyancy body 1 adopts a low-density, hollow, high-contrast color, i.e., a marking portion design, such as a carbon fiber composite material with a specific hollow structure design or a titanium alloy with a porous structure, which maintains a high mechanical strength while reducing the density. After approaching the rescue target and being opened in a controlled manner, it still has a certain buoyancy and carrying capacity, which can provide buoyancy support for the rescued personnel and facilitate the rescued personnel and rescuers to find each other; the buoyancy body 1 can withstand long-term corrosion from seawater and keep its own functions intact, while being able to effectively avoid the attachment of organisms, and is environmentally friendly as a whole.

[0043] In the optional scheme of this embodiment, it is more preferred that the sensing mechanism 4 and the signal receiving mechanism 5 are both circumferentially arranged at the front end of the floating body 1 to facilitate all-round detection or signal reception.

[0044] Specifically, in order to ensure the long-term storage requirements of the device, the signal receiving mechanism 5 adopts a low-power receiving device. The signal receiving mechanism 5 adopts an existing specialized underwater acoustic communication device. The core part of the device is a hydrophone, which can convert sound waves into electrical signals. It is usually composed of one or more piezoelectric ceramic elements distributed around the buoyant body 1. These elements will generate voltage when subjected to sound wave pressure. Since the underwater sound wave signal may be very weak, the underwater acoustic communication equipment usually includes a low-noise pre-amplifier to enhance the signal without introducing too much noise. The received electrical signal needs to be filtered, amplified and digitized, and sent to the control component 7 for subsequent decoding and analysis; in addition, the signal receiving mechanism 5 can also use other underwater communication devices on the market, as long as it can achieve underwater communication.

[0045] Specifically, in order to meet the demand for locating the rescue target, the sensing mechanism 4 adopts the existing high-precision sonar sensing detection device to ensure the positioning accuracy. At the same time, it needs to have a certain information processing capability to identify and lock the rescue target. The sonar sensing detection device can use sonar to detect targets and is specifically used for the detection, positioning and identification of underwater targets. The sonar system includes one or more transmitters distributed around the buoyant body 1 to generate sound wave pulses. These transmitters can be transducers, which can convert electrical signals into sound waves. At the same time, the transducers can not only act as transmitters but also as receivers. They can emit sound wave pulses and receive these echoes when the sound waves encounter the target and reflect back. Subsequently, the sound wave signal received by the signal processing unit is amplified, filtered and digitized. Finally, the received sound wave signal is analyzed using a data processing program to extract the target's position, speed and other or predicted position information and send it to the control component 7, and the information is passed to the attitude control system 4 to control the attitude control system; in addition, the sensing mechanism 4 can also use other detection devices on the market as long as it can achieve target detection and positioning.

[0046] In the optional scheme of this embodiment, it is more preferred that the attitude control mechanism 6 includes a driving mechanism and a plurality of swept wings 61 movably arranged on the tail wall of the buoyant body 1, the driving mechanism is communicated with the control component 7, the driving mechanism can control the deflection of the swept wings 61 relative to the buoyant body 1, and the steering of the buoyant body 1 is achieved by controlling the deflection of the corresponding swept wings 61.

[0047] Specifically, four or more swept wings 61 are used to enhance the stability and maneuverability of the floating body 1. The swept wings 61 can be made of carbon fiber composite materials with a specific hollow structure design or titanium alloys with a porous structure. While reducing the density, the density can be maintained at a high mechanical strength. The weight can be reduced while maintaining the structural strength, and the speed can be increased. At the same time, the rudder surface can use a triangular swept wing structure to further reduce the impact on the floating speed. At the same time, the swept wings 61 also need to have a certain area to provide sufficient control force. When maneuvering is required, the driving mechanism controls the swept wings 61 to deflect, and a force is generated on the rudder surface to cause the stern of the floating body 1 to deflect in the direction of the deflection of the rudder surface, thereby making the floating body 1 turn. The driving mechanism may include multiple flip motors, which are arranged in the floating body 1 and are respectively connected to the multiple swept wings 61 to achieve separate deflection control. The attitude control mechanism 6 can achieve precise control of the attitude and heading of the floating body 1 by accurately controlling the deflection angle and duration of the swept wings 61. In addition, the attitude control mechanism 6 can also use other attitude control devices on the market as long as attitude control can be achieved.

[0048] In the optional scheme of this embodiment, more preferably, the control component 7 can be controlled by inputting a specified program into a conventional single-chip microcomputer, FPGA or other modules or a dedicated control module.

[0049] Embodiment 2

[0050] This embodiment provides a deep-sea unpowered buoyancy method, based on the deep-sea unpowered buoyancy rescue device as in the first embodiment, comprising the following steps:

[0051] The signal receiving mechanism 5 receives external rescue signals; see Figure 5 The signal receiving mechanism 5 can receive signals from the surroundings of the floating body 1 from the distant land-based, water-based, and air-based signals, and send the received start signal to the control component 7. The signal receiving mechanism 5 only performs passive signal information reception and does not include an active signal transmitting device. Before the overall system is started, long-term underwater signal information reception and decoding are performed. During this period, the operating power consumption is extremely low, which can support the long-term underwater deployment of this device;

[0052] The control component 7 activates the sensing mechanism 4 to search, match and lock the rescue target according to the external rescue signal;

[0053] After locking the rescue target, the control component 7 controls the connection mechanism 3 to move, so that the floating body 1 is separated from the counterweight mechanism 2, and the floating body 1 performs unpowered floating;

[0054] During the unpowered buoyancy, the sensing mechanism 4 continuously tracks the rescue target, and the control component 7 controls the attitude control mechanism 6 to control the attitude of the buoyancy body 1; the control component 7 continuously receives the signal from the control component 7, and adjusts the buoyancy attitude of the buoyancy body 1 quickly and accurately according to the signal, so that it can accurately float toward the rescue target;

[0055] After approaching the target and after the induction mechanism 4 transmits a start signal, the control component 7 controls the switch door of the material chamber 11 to open, so that the internal rescue materials are released through the switch door.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
