[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] like Figure 1 As shown, the present embodiment discloses an ocean drifting buoy with a self-destruction function, comprising a buoy body and a self-destruction module. The buoy body comprises a top cover 1, a pressure cover 2 and a float 4. The top cover 1 is made of a transparent PC material, the pressure cover 2 is made of an ABS material through an injection molding process, the float 4 is integrally formed through a rotational molding process, a data acquisition module is installed inside the float, the pressure cover and the top cover are connected to the float above by bolts, a solar cell panel 3 is arranged on the side of the float 4 near the pressure cover, and five handles 7 are circumferentially arranged on the end of the float 4 near the pressure cover 2, the handles 7 are integrally formed with the float 4, and since the rotational molding material is a non-metallic material and does not have an electromagnetic shielding function, the data acquisition module is placed in a rotationally molded sealed cabin inside the rotational molding shell, the electromagnetic waves of the radar antenna of the data acquisition module can penetrate the rotational molding shell, the radar antenna is placed on the ceiling of the rotational molding shell, the rotational molding shell floats on the sea surface, and the radar and the antenna will not be affected by being buried by seawater. Solar panels are installed on the corresponding floating bodies above adjacent handles, and fixing holes 8 are provided on the handles 7. This design utilizes the 5-point anti-collision ring on the outermost edge to achieve the outer anti-collision protection effect for the entire buoy, and can also realize the function of the handle through the angle gap between the 5 sides and the float. At the same time, through this structure, the effect of increasing the rotational molding material on the structural level is achieved, thereby increasing the strength of the buoy and making the appearance smooth.
[0028] The inner wall of the floating body 4 is provided with a sensing module near the end of the pressure cover. The self-destruction module includes a self-sinking structure 5 and a self-destruction circuit. The self-destruction circuit is connected to the data acquisition module. The self-destruction circuit controls the burning of the main chip and the storage through the 3.3v power pin. The specific self-destruction circuit is as follows Fig. 9 As shown, the self-sinking structure 5 is installed on one side of the bottom of the floating body 4, and the self-sinking structure 5, the self-destruction circuit, and the sensing module are all connected to the control module.
[0029] The bottom of the floating body is also provided with three external sensor connectors 6, such as Figure 2 As shown, a lifting ring 9 is provided at the bottom of the floating body, and the lifting ring 9 is pre-buried in the floating body when the floating body is integrally formed by the rotational molding process.
[0030] like Figure 3 As shown, the sensing module includes a cover opening detection switch 12, a magnetically controlled reed switch 10, and a pressure plate 11. A pressure plate 11 is arranged above the cover opening detection switch 12. The cover opening detection switch 12 and the magnetically controlled reed switch 10 are both connected to the control module. In actual operation, when the hatch of the buoy is closed, the hatch presses the pressure plate 11, and the pressure plate presses the cover opening detection switch 12. If the buoy needs to be repaired, a magnet is placed above the top cover, and the magnet acts on the magnetically controlled reed switch 10. The magnetically controlled reed switch sends a signal to the control module, and the control module controls the self-destruct circuit not to work. At this time, the hatch is opened for maintenance; if the hatch is opened directly, the pressure plate 11 does not press the cover opening detection switch 12, and the cover opening detection switch pops up. At this time, the control module controls the self-destruct circuit to work, and the self-destruct circuit burns the data acquisition module to ensure data security.
[0031] like Figure 4-7 As shown, the self-sinking module includes a fixed seat 18, a mounting shaft 14, a sleeve 19, a paddle 22, a sliding pin 13, a tension spring 15, and a cotton thread 17. The fixed seat 18 is fixedly connected to the mounting shaft 14 through the sleeve 19. A rotatable paddle 22 is arranged in the gap between the fixed seat 18 and the mounting shaft 14. Through holes are arranged in the middle of the paddle 22, the fixed seat 18, and the mounting shaft 14. The hook of the paddle 22 extends to the outside of the gap. A sliding pin 13 is arranged in the through hole of the fixed seat 18. The sliding pin 13 is a "cross" structure, and a spring is sleeved below the sliding pin 13. 24, a fixing column 16 is provided at one end of the sleeve 19 near the gap, one end of the tension spring 15 is fixed to the fixing column 16, and the other end is connected to the hook of the pick 22, one end of the cotton thread 17 is fixed to the fixing column 16, and the other end is connected to the hook of the pick, a heating wire 20 is sleeved on the outer surface of the cotton thread 17, and the heating wire 20 is fixed by a heating wire fixing block 21, and the heating wire fixing block 21 is installed on one side of the installation shaft 14, a groove is provided at the bottom of the sliding pin 13, an O-ring 23 is provided in the groove, and the diameter of the sliding pin 13 at one end near the installation shaft 14 is smaller than the diameter of the other end.
[0032] In this embodiment, the through hole in the fixing seat is an inverted convex structure. Under normal circumstances, the spring is pressed against the inner wall of the through hole of the fixing seat 18 in a compressed state. The groove on one side of the paddle 22 is misaligned with the shaft sleeve 19 and the through hole of the fixing seat 18. The top of the sliding pin is pressed against the paddle. The specific structure is as follows: Figure 8 shown.
[0033] In this embodiment, when the self-sinking structure is in a normal state, the top of the sliding pin rests on the paddle, the groove on the side of the paddle is staggered with the through hole of the fixed seat and the mounting shaft, the tension spring and the cotton thread are connected to the paddle hook at the same time, and the tension spring is in a stretched state. The tension of the tension spring and the cotton thread on the hook keeps the force balance of the hook. The control module is equipped with a time monitoring unit and a positioning module. When the buoy runs to the designed time or monitors that the buoy exceeds the designated area, the control module controls the self-sinking structure to start, and the heating wire heats and burns the cotton thread. At this time, the tension spring resets and pulls the paddle to the side of the tension spring. At this time, the groove on the side of the paddle coincides with the through hole of the fixed seat and the mounting shaft, and the sliding pin moves upward under the push of the spring. At this time, a gap appears in the through hole of the bottom fixed seat, and seawater enters the floating body from the through hole of the fixed seat, causing the buoy to sink.
[0034] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
