DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] Example 1

[0026] See also Figure 1-5A deep-sea observation platform emergency communication buoy comprises a base 1 fixed on the observation platform, a buoy assembly 2 detachably connected to the base 1, a positioning module 21 being provided on the buoy assembly 2, a first connecting portion 11 being provided on the base 1, a second connecting portion 22 being provided on the buoy assembly 2, the first connecting portion 11 and the second connecting portion 22 being detachably connected, a pushing assembly 12 for pushing the second connecting portion 22 to separate the second connecting portion 22 from the first connecting portion 11 being further provided on the base 1, and after the second connecting portion 22 is separated from the first connecting portion 11, the buoy assembly 2 floats to the water surface.

[0027] In practical applications, the buoy assembly 2 is connected to the base 1 through the second connection part 22 and the first connection part 11, and the base 1 is fixed on the observation platform. It should be noted that the observation platform mentioned here is located under the sea surface, specifically, in the deep sea area with a depth of more than 2000 meters. Specifically, in this embodiment, the first connection part 11 and the second connection part 22 are in an interference fit manner, that is, the top of the first connection part 11 is provided with a mounting part, and the bottom of the second connection part 22 is provided with a mounting groove, and the mounting part is plugged into the mounting groove. The buoy assembly 2 is installed in the groove, and the matching mode of the installation part and the installation groove is interference fitting, so that the buoy assembly 2 is connected to the base 1. When the buoy assembly 2 and the base 1 need to be separated, the second connection part 22 is lifted up by pushing the assembly 12, so that the second connection part 22 and the first connection part 11 are separated, and the buoy assembly 2 floats to the water surface. The staff can search and recover the buoy assembly 2 through the positioning module 21, and then obtain the communication information and data on the buoy assembly 2. On the other hand, the buoy assembly 2 and the base 1 can be reconnected in this way.

[0028] Preferably, a cable 13 is provided in the base 1, and the cable 13 is electrically connected to the first connecting part 11, and the cable 13 is electrically connected to the observation platform; when the first connecting part 11 is inserted into the second connecting part 22, the cable 13 is energized and electrically connected to the second connecting part 22 through the first connecting part 11; when the first connecting part 11 is separated from the second connecting part 22, the cable 13 is de-energized.

[0029] In the above design, the observation platform, the base 1, and the buoy assembly 2 transmit electrical signals and electrical energy through the cable 13. Specifically, the base 1 can communicate and power the observation platform through RS485 through the cable 13. When the buoy assembly 2 is connected to the base 1, the cable 13 is electrically connected to the buoy assembly 2 through the first connection part 11 and the second connection part 22. Specifically, the inside of the first connection part 11 and the second connection part 22 is in contact with a conductive material, while the outer shell is an insulating material. Therefore, the cable 13 can be connected through the first connection part 11 and the second connection part 22, and then electrically connected to the buoy assembly 2, and when the first connection part 11 and the second connection part 22 are separated, the cable 13 is powered off to avoid affecting the surrounding ecology.

[0030] Preferably, the pushing assembly 12 includes a driving motor 121, a fixed column 122 connected to the power output part of the driving motor 121, and a movable block 123 threadedly connected to the fixed column 122. A column 27 is provided at the bottom of the buoy assembly 2, and a housing cavity 271 for accommodating the movable block 123 is provided in the column 27. The driving motor 121 is connected to the base 1, and the driving motor 121 is used to drive the fixed column 122 to rotate. When the fixed column 122 rotates, the movable block 123 moves along the length direction of the fixed column 122, and the second connecting part 22 is separated from the first connecting part 11 by pushing the column 27.

[0031] In the present embodiment, the driving motor 121 can drive the fixed column 122 to rotate. Specifically, in the present embodiment, the fixed column 122 and the power output part of the driving motor 121 are connected by a key connection. When the driving motor 121 rotates, the fixed column 122 will also rotate synchronously with the driving motor 121. At this time, the movable block 123 can move along the length direction of the fixed column 122 as the fixed column 122 rotates. Specifically, when the fixed column 122 is driven by the driving motor 121, the movable block 123 can move along the length direction of the fixed column 122 through a thread, and push the column 27, thereby lifting the second connection part 22, so that the second connection part 22 is separated from the first connection part 11, thereby releasing the buoy. In particular, the contact between the top of the fixed column 122 and the bottom of the accommodating cavity 271 can ensure that the movable block 123 can push the column 27, and is conducive to increasing the stroke of the movable block 123 to push the column 27, so that the first connection part 11 and the second connection part 22 of the interference fit can be separated.

[0032] More preferably, the buoy assembly 2 is provided with a solenoid valve 23 , and the solenoid valve 23 is located above the second connecting portion 22 . The solenoid valve 23 is used to balance the internal and external pressures of the buoy assembly 2 .

[0033] Through the above design, the solenoid valve 23 can control the pressure difference between the inside and outside of the buoy assembly 2. Specifically, when the buoy assembly 2 is connected to the base 1, the solenoid valve 23 is in a closed state, and the pressure of the buoy assembly 2 is atmospheric pressure. When it is necessary to balance the pressure difference between the inside and outside of the buoy assembly 2, the solenoid valve 23 is changed to an open state, so that the pressure difference between the inside and outside of the buoy assembly 2 is close to 0, thereby reducing the resistance to the separation of the buoy assembly 2 from the base 1. That is to say, when the buoy assembly 2 does not need to be separated, the solenoid valve 23 can be closed to further enhance the connection strength between the buoy assembly 2 and the base 1; when the buoy assembly 2 needs to be separated, the solenoid valve 23 can be opened to reduce the force required for the separation of the buoy assembly 2, and it can be easier to lift the second connecting part 22 by pushing the assembly 12, so that the buoy assembly 2 is separated from the base 1 and floats to the water surface.

[0034] More preferably, the buoy assembly 2 is provided with a first shell 24 , in which a power supply 25 and a communication unit 26 are provided, the power supply 25 is electrically connected to the communication unit 26 , the communication unit 26 is electrically connected to the positioning module 21 , and the second connecting portion 22 is located in the first shell 24 .

[0035] In this embodiment, the material of the first shell 24 is a pressure-resistant material, which is conducive to the stable operation of the buoy assembly 2 under deep-sea pressure at a depth of more than 2000 meters, and the buoy assembly 2 will not be damaged due to the deep-sea high-pressure environment. On the other hand, the power supply 25 provides operating energy for the communication unit 26 and the positioning module 21. Specifically, the positioning module 21 in this embodiment specifically refers to Beidou satellite positioning. More specifically, the positioning module 21 is located on the top of the buoy assembly 2, which allows the buoy assembly 2 to float to the surface of the water. The positioning module 21 can be located above the water surface, which is conducive to obtaining positioning information, and the communication unit 26 plays the role of communication, collection and command issuance.

[0036] More preferably, a second shell 14 is provided on the base 1 , the first connecting portion 11 is located on the second shell 14 , the pushing assembly 12 is located in the second shell 14 , and the second shell 14 is connected to the first shell 24 via the first connecting portion 11 and the second connecting portion 22 .

[0037] In this embodiment, the material of the second shell 14 is a pressure-resistant material, which is conducive to the base 1 being more stable under deep-sea pressure at a depth of more than 2000 meters. On the other hand, the first shell 24 and the second shell 14 are connected by the first connecting part 11 and the second connecting part 22. When the first connecting part 11 and the second connecting part 22 are separated, the first shell 24 and the second shell 14 will also be separated, so that the second shell 14 floats to the water surface with the buoy assembly 2.

[0038] More preferably, a control unit 15 is disposed in the second housing 14 , and the control unit 15 is used to receive an external signal to activate the pushing component 12 .

[0039] Through the above design, the control unit 15 can receive external information, mainly information about separating the buoy component 2 and the base 1, and drive the pushing component 12 to move, separate the buoy component 2 and the base 1, and the buoy component 2 floats to the water surface to facilitate the staff to recover and read the internal information and data.

[0040] More preferably, flange bolts 16 for fixing the base 1 on the observation platform are provided at the bottom of the base 1.

[0041] In this embodiment, the base 1 can be fixed on the observation platform by flange bolts 16, which can prevent the base 1 from falling off or dropping on the observation platform.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
