[0055] like Figures 1 to 11 As shown, a beacon device can be used for underwater positioning, comprising:

[0056] A first driving unit including a first circuit board 29, a second driving unit including a second circuit board 36 and a piezoelectric ceramic ring 12; the piezoelectric ceramic ring 12 can emit a first sound signal under the drive of the first driving circuit; the piezoelectric ceramic ring 12 can emit a second sound signal under the drive of the second driving circuit;

[0057] The first driving unit further includes a first housing 21 having a first opening and a second opening, and the second driving unit further includes a second housing 31 having a third opening and a fourth opening, the first opening of the first housing 21 and the fourth opening of the second housing 31 are screwed together by threads, and the piezoelectric ceramic ring 12 is potted below the second opening of the first housing 21;

[0058] When the first housing 21 and the second housing 31 are screwed together, the first drive circuit in the first housing 21 and the second electric drive circuit in the second housing 31 are in a connected state.

[0059] In one embodiment, a push button slot 211 is provided on the outer wall of the first shell 21, and the push button 23 is slidably installed in the push button slot 211. A circular blind hole is provided on the bottom surface of the push button slot 211, and an elastic self-locking pin is installed in the circular blind hole. The elastic self-locking pin includes a steel ball 24 and a steel ball compression spring 25. Two self-locking pin grooves 212 are correspondingly provided on the bottom surface of the push button 23; the bottom of the push button 23 is also provided with a groove 213 for accommodating the first magnet 210; when the first magnet 210 slides away from the first circuit board 29 in the push button slot 211 along with the push button 23, one of the self-locking pin grooves corresponds to the circular blind hole, the steel ball is embedded in the self-locking pin groove, and the first drive circuit is in an open state; when the first magnet 210 slides close to the first circuit board 29 in the push button slot 211 along with the push button 23, the other self-locking pin groove is aligned with the circular blind hole, the steel ball is embedded in the self-locking pin groove, and the first drive circuit is in a closed state; when the first drive circuit is closed, the piezoelectric ceramic ring 12 emits a first sound signal.

[0060] In another embodiment, a first flux chip is provided on the first circuit board 29. Initially, the first magnet 210 under the push button 23 is away from the first circuit board 29 and the first flux chip on the circuit board, and the first drive circuit is in a disconnected state. The first flux chip is a single-stage Hall effect switch with a magnetic operating threshold (Bop). If the magnetic flux density borne by the Hall unit is greater than the operating threshold, the output transistor will turn on; when the magnetic flux density decreases to below the operating threshold (Bop), the transistor will turn off.

[0061] In one embodiment, the first shell 21 is provided with a first opening end cover near the thread of the inner wall of the first opening, an O-ring 22 is provided under the first opening end cover, and a copper ring 27 is provided on the first opening end cover 26, and the copper ring 27 is used to communicate with the circuit inside the second drive unit; at the same time, the first circuit board 29 is connected to the copper ring 27 through a wire.

[0062] In another embodiment, a foam bushing 11 is provided above the piezoelectric ceramic ring 12, and an aluminum cover 13 is provided below the piezoelectric ceramic ring 12. The piezoelectric ceramic ring 12, the foam bushing 11 and the aluminum cover 13 are encapsulated with epoxy resin below the second opening of the first shell 21. After encapsulation, an epoxy resin sleeve 14 is formed around the foam bushing 11, the piezoelectric ceramic ring 12 and the aluminum cover 13.

[0063] In one embodiment, an end cover is provided at the third opening of the second shell 31, a groove is provided on the end cover of the third opening, a button compression spring 35 is fixed in the groove, and a second magnet is provided on the button compression spring 35. The second magnet approaches the bottom of the groove of the third opening end cover as the button compression spring 35 is compressed, and moves away from the bottom of the groove of the third opening end cover as the button compression spring 35 is lifted; a second circuit board 36 is provided in the second shell below the third opening end cover, and a second magnetic flux chip is provided on the second circuit board 36.

[0064] In one embodiment, initially, the second magnet on the button compression spring 35 is away from the bottom of the groove of the third opening end cover, the second circuit board 36 under the end cover and the second flux chip on the second circuit board 36, and the second drive circuit are in a disconnected state. The second flux chip is a single-stage Hall effect switch with a magnetic operating threshold (Bop). If the magnetic flux density borne by the Hall unit is greater than the operating threshold, the output transistor will turn on; when the magnetic flux density decreases to below the operating threshold (Bop), the transistor will turn off.

[0065] In another embodiment, a fourth opening end cover is provided at the fourth opening of the second shell 31. After the fourth opening of the second shell 31 is screwed and connected with the first opening of the first shell 21 through the threads on the inner wall of the shell, the fourth opening end cover of the second shell and the first opening end cover of the first shell isolate the interior of the second shell from the interior of the first shell, thereby maintaining the mutual independence of the interiors of the two shells.

[0066] In one embodiment, a through hole is provided on the fourth opening end cover, through which a copper needle 39 fixed inside the second shell 31 can pass. When the first shell 21 and the second shell 31 are threadedly connected, as the thread is tightened, the copper needle 39 extending from the fourth opening end cover contacts the copper ring 27 provided on the first opening end cover. Since the second circuit board 36 is connected to the copper needle 39 through a wire, the first drive circuit in the first shell is connected to the second drive circuit in the second shell.

[0067] In another embodiment, in order to adjust the connection strength and facilitate disassembly, a copper needle compression spring 310 is sleeved on the copper needle 39. When the copper needle 39 extends out of the fourth opening end cover, the copper needle compression spring 310 is resisted by the copper needle clamp 38 arranged at the through hole of the fourth opening end cover, thereby ensuring that the connection has a certain elasticity.

[0068] In one embodiment, a bracket 312 is fixedly arranged on the inner wall of the shell near the fourth opening inside the second shell, and a through hole is arranged on the bracket 312, through which the copper needle 39 passes, and a baffle 311 is arranged at one end of the through hole to limit the axial displacement of the copper needle 39 during the tightening or loosening process. In another embodiment, for the convenience of carrying, a beacon hanging rope 313 is arranged on the outer wall of the second shell 31. The upper part of the third opening groove of the second shell is covered with an elastic material, and an SOS button 33 is arranged. Pressing the SOS button 33 will cause the compression of the button compression spring 35, so that the second driving circuit is closed, and the piezoelectric ceramic ring 12 is driven to emit a second sound signal. An SOS lamp 32 can also be arranged on the outer wall of the second shell. When the second driving circuit is closed, the SOS lamp 32 is activated to emit a bright light.

[0069] When using the beacon device, if the push button 23 is pushed to close the first drive circuit, the beacon device is turned on, and the piezoelectric ceramic ring 12 in the beacon device emits a first sound signal; in an emergency, the SOS button 33 can also be pressed, and the second drive circuit is closed, the piezoelectric ceramic ring 12 in the beacon device emits a second sound signal, and the SOS lamp 32 is activated to emit a bright light.

[0070] A battery 37 is arranged inside the second shell 31. When the first shell and the second shell are screwed together, one end of the copper needle 39 is connected to the copper ring 27, and the other end is connected to the battery 37. At this time, the battery 37 can provide electrical energy for the first drive circuit. At the same time, the battery 37 is also connected to the second circuit to provide electrical energy for the second drive circuit.

[0071] In one embodiment, the circuit distribution of the first driving circuit and the second driving circuit is as follows: Fig.12 shown.

[0072] When using this device, you can push the button to turn on or off the beacon device at any time on the shore or underwater as needed. After the beacon is turned on, it can send a signal of a characteristic frequency. The shore-side equipment can locate the beacon based on the received signal. When underwater personnel encounter danger underwater and need help, they can press and hold the SOS button to quickly call for help underwater. The shore-side equipment will quickly go to the rescue location for rescue based on the received distress signal and beacon positioning. When the beacon completes its mission and returns to the shore, the second drive unit can be plugged into the charger base for quick charging.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
