Description

[0002] With the deepening of global development of marine resources, underwater detection equipment is increasingly used in the fields of marine surveys, geological exploration, deep-sea environmental monitoring, etc. Usually, after the operation of these devices is completed, the beacon system will be released for salvage and recovery.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] refer to Figures 1 to 3 A communication buoy system with a position indicating and recovery function comprises a signal transmitting module 1, an inflation module 2, a tether module 3, and a separation module 4 which are connected in sequence; the signal transmitting module 1 is provided with an air bag 6; a cable 35 is wound in the tether module 3, and the free end of the cable 35 is connected to the separation module 4; the separation module 4 is provided with an underwater positioning unit 5;

[0033] The separation module 4 can separate itself from the tether module 3 and sink by its own gravity;

[0034] When the separation module 4 sinks, the cable 35 is pulled to release the cable 35 in the tether module 3;

[0035] The inflation module 2 is used to inflate the airbag 6 so that the signal transmitting module 1 floats to the water surface.

[0036] It should be noted here that the signal transmission module 1, the inflation module 2 and the tether module 3 have positive buoyancy; the separation module 4 and the underwater positioning unit 5 have negative buoyancy.

[0037] Under this design, the system is connected to the ship, and the ship tows the system through the water to a suitable position and then stops, and the system is disconnected from the ship. The system sinks by the gravity of the separation module 4 and the underwater positioning unit 5. After sinking to a certain depth, the underwater positioning unit 5 sends a separation signal to the separation module 4, and the separation module 4 is separated from the tether module 3. The separation module 4 sinks by its own gravity and pulls the cable 35 to release the cable 35. The signal transmitting module 1, the inflation module 2 and the tether module 3 float to a certain height by buoyancy, and then the inflation module 2 inflates the airbag 6, so that the signal transmitting module 1 can float to the water surface and transmit a signal to recover the system.

[0038] In this embodiment, the signal transmitting module 1 includes a first shell 11, a first control board 12, a sensor 13 and a sensing switch 14 arranged in the first shell 11, one end of the first shell 11 is connected to the inflation module 2, the airbag 6 is arranged on the first shell 11, an antenna 16 is arranged on the first shell 11, the first control board 12, the sensor 13 and the sensing switch 14 are communicatively connected, and the first control board 12 is connected to the inflation module 2 through a cable 7;

[0039] The inflation module 2 includes a second shell 21 and a gas cylinder 22. The gas cylinder 22 has a first bracket 221 and a second bracket 222 at both ends. One end of the second shell 21 is connected to the first shell 11, and the other end is connected to the first bracket 221. The second bracket 222 is connected to the tether module 3.

[0040] The second housing 21 is provided with a second control board 24, a first battery 25 and a solenoid valve 23, the gas cylinder 22 is provided with an air outlet pipe 223, the air bag 6 is provided with an air inlet pipe 61, and the air outlet pipe 223 and the air inlet pipe 61 are connected and disconnected by the solenoid valve 23;

[0041] The first battery 25 is electrically connected to the second control board 24 , the second control board 24 is electrically connected to the solenoid valve 23 , and the first control board 12 and the second control board 24 are electrically connected via a cable 7 .

[0042] Further, after sinking to a certain depth, the separation module 4 is separated from the tether module 3, so that the tether module 3, the gas cylinder 22 and the signal transmission module 1 can float up by buoyancy, and when the first control board 12 collects the preset first pressure index of the sensor 13, the first battery 25 mainly serves to power the solenoid valve 23, and then the induction switch 14 is turned on, and the first control board 12 transmits the signal to the second control board 24 through the cable 7, and the second control board 24 controls the solenoid valve 23 to open, and the gas of the gas cylinder 22 enters the air bag 6 through the outlet pipe 223 and the inlet pipe 61 to inflate the air bag 6 to provide greater buoyancy to float to the surface of the water;

[0043] After floating to the surface, the first control panel 12 collects the preset second pressure index sensed by the sensor 13 and then issues a communication instruction, and establishes a connection with the remote control terminal through the antenna 16 to send information to the staff for easy recovery.

[0044] Preferably, a hook 15 is further provided on the first shell 11. Providing the hook 15 on the first shell 11 can facilitate the recycling of the system.

[0045] More preferably, the tether module 3 comprises a third shell 31 and a hollow drum 32 horizontally arranged in the third shell 31, one end of the third shell 31 is connected to the inflation module 2, and the other end is detachably connected to the separation module 4; a fixing member 33 is arranged in the third shell 31, the cable 35 is wound on the hollow drum 32, one end of the cable 35 is fixed on the fixing member 33, and the other end is connected to the separation module 4;

[0046] The separation module 4 includes a fourth housing 41, a motor 42 disposed in the fourth housing 41, a second battery 47, a third control board 45 and a reducer 43, the rotating shaft of the motor 42 is connected to the reducer 43, a connecting plate 49 is disposed in the fourth housing 41, and the reducer 43 is connected to the connecting plate 49;

[0047] One end of the third housing 31 is provided with a first flange 34, one end of the fourth housing 41 is provided with a second flange 48 matching the first flange 34, the first flange 34 and the second flange 48 are interlocked, and one end of the cable 35 is connected to the second flange 48;

[0048] The inner wall of the hollow drum 32 has threads, and the output end of the reducer 43 is provided with a threaded column 44, which passes through the second flange 48 and the center hole of the first flange 34 in sequence and is then threadedly connected in the hollow drum 32;

[0050] Specifically, the cable 35 is wound on the hollow drum 32, one end of the cable 35 is connected to the fixing member 33, and the other end is connected to the second flange 48. The second battery 47 is mainly used to power the motor 42. The hydrophone sends a signal to the third control board 45. When the third control board 45 receives the signal, it controls the action of the motor 42 and the action of the reducer 43 to drive the threaded column 44 to rotate, thereby causing the threaded column 44 to detach from the hollow drum 32, and then the first flange 34 and the second flange 48 will be separated. Since one end of the cable 35 is connected to the second flange 48, the cable 35 will be pulled and released under the action of gravity. Before the cable 35 is straightened, the signal transmitting module 1, the inflation module 2 and the gas cylinder 22 will float up by buoyancy. After floating up for a distance, the airbag 6 is inflated by the inflation module 2 to provide greater buoyancy so that the signal generating module reaches the water surface.

[0051] In this embodiment, the separation module 4 is provided with a protective cover 46 for protecting the underwater positioning unit 5. The protective cover 46 protects the underwater positioning unit 5, thereby reducing the risk of damage to the underwater positioning unit 5 due to impact.

[0052] Preferably, a through hole 411 for connecting with an external device is provided on the third housing 31. The through hole 411 is used to connect with an external device so that the system can be towed to sail in the water.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the scope of protection of the present invention.
