[0029] Please see Figures 1 to 3 This application provides a diving device, which can be an unmanned surface vessel, an underwater detector, or other diving equipment.

[0030] The diving equipment includes a positioning buoy 100, a diving hull, and a communication module.

[0031] The positioning buoy 100 is hinged to the hull of the submarine. When the submarine is submerged, the positioning buoy 100 can partially float on the water surface under the buoyancy of the water, so that the positioning buoy 100 can communicate with the Beidou satellite.

[0032] The communication module is located inside the submarine. The positioning buoy 100 can communicate with the communication module to provide navigation and positioning information to the submarine.

[0033] In some embodiments, the positioning buoy 100 includes a connecting rod 110, a buoyancy component 130, and a Beidou antenna 150.

[0034] The connecting rod 110 has a first hinge portion 1133 and a first mounting portion 1153 at both ends along the length direction X. The first hinge portion 1133 is used to hinge to the outside of the submarine hull. The buoyancy member 130 is connected to the first mounting portion 1153. The buoyancy member 130 can float on the water surface. Thus, when the submarine hull is submerged, the buoyancy member 130 can drive the connecting rod 110 to rotate relative to the submarine hull under the buoyancy of the water, so that the buoyancy member 130 can float on the water surface.

[0035] The Beidou antenna 150 is connected to the buoyancy component 130 and is partially exposed outside the buoyancy component 130, so that the Beidou antenna 150 can float on the water surface with the buoyancy component 130, so that the Beidou antenna 150 can communicate with the Beidou satellite. The specific working principle of the Beidou antenna 150 can be referred to the existing technology, and will not be repeated here.

[0036] The connecting rod 110 has an installation channel 111 running through it along the length direction X. The first communication line 170 extends through the installation channel 111, with one end connected to the Beidou antenna 150 and the other end exposed outside the installation channel 111 for connecting to the communication module. Thus, the first communication line 170 can transmit the communication signal between the Beidou antenna 150 and the Beidou satellite to the communication module to provide navigation and positioning information for the submersible hull, thereby enabling the positioning buoy 100 to achieve underwater positioning.

[0037] When the positioning buoy 100 is applied to the diving equipment, the first hinge 1133 is hinged to the outside of the diving vessel hull, and one end of the first communication line 170 is connected to the Beidou antenna 150, and the other end is connected to the communication module.

[0038] The positioning buoy 100 provided in this application embodiment can float the Beidou satellite on the water surface through the buoyancy component 130, so that the Beidou antenna 150 can communicate with the Beidou satellite to provide navigation, positioning and other information for diving equipment. Compared with the underwater positioning technology in related technologies, the positioning buoy 100 provided in this application embodiment can achieve underwater positioning through the Beidou antenna 150, and the overall structure is simpler and the manufacturing cost is lower.

[0039] In some embodiments, the connecting rod 110 may include a first support rod 113 and a second support rod 115.

[0040] The first support rod 113 can pass through the first channel 1131 along the length direction X, and the second support rod 115 can pass through the second channel 1151 along the length direction X. The first support rod 113 can be movably inserted through the second channel 1151 along the length direction X and can partially extend out of the second channel 1151. Thus, the first support rod 113 and the second support rod 115 can move relative to each other to lengthen or shorten, thereby adjusting the length of the connecting rod 110.

[0041] The first channel 1131 and the second channel 1151 are interconnected to form an installation channel 111, that is, the first communication line 170 can be extended through the first channel 1131 and the second channel 1151.

[0042] One of the first support rod 113 and the second support rod 115 is provided with a first hinge portion 1133, and the other is provided with a first mounting portion 1153. Thus, when the submarine hull is submerged, the buoyancy member 130 floats on the water surface under the buoyancy of the water, and the first support rod 113 and the second support rod 115 move relative to each other to extend the length of the connecting rod 110, thereby increasing the diving depth of the submarine hull while the buoyancy member 130 can float on the water surface. When the submarine hull is surfaced, the second support rod 115 can move under the action of gravity, so that the first support rod 113 can retract into the second channel 1151, thereby shortening the length of the connecting rod 110 and reducing the space occupied by the positioning buoy 100 outside the submarine hull.

[0043] As an example, the second support rod 115 has a first port and a second port opposite each other along the length direction X. The first support rod 113 can extend out of the second channel 1151 or retract into the second channel 1151 through the first port. Specifically, the end of the second support rod 115 with the second port may have a first mounting portion 1153, and the end of the first support rod 113 extending out of the first port may have a first hinge portion 1133; or the end of the second support rod 115 with the second port may have a first hinge portion 1133, and the end of the first support rod 113 extending out of the first port may have a first mounting portion 1153.

[0044] It should be noted that the retraction of the first support rod 113 into the second channel 1151 can mean that the first support rod 113 partially retracts into the second channel 1151.

[0045] For ease of description, the following explanation will take the example of the second support rod 115 having a first mounting part 1153 and the first support rod 113 having a first hinge part 1133.

[0046] In some embodiments, the first support rod 113 and the second support rod 115 can be limited by a limiting structure to prevent the first support rod 113 and the second support rod 115 from separating from each other.

[0047] As an example, the outer periphery of the end of the first support rod 113 located within the second channel 1151 may be provided with a first limiting portion, and the inner wall of the second support rod 115 at one end of the first port may be provided with a second limiting portion. The end portion of the first support rod 113 facing away from the first limiting portion extends outside the second channel 1151. The first limiting portion movably contacts the inner wall of the second channel 1151, and the outer periphery of the first support rod 113 movably contacts the second limiting portion. This allows the first support rod 113 and the second support rod 115 to be supported at multiple positions, helping to reduce relative swaying between the first and second support rods 113 and 115. The first limiting portion may be located within the movement path of the second limiting portion to block the second limiting portion, thereby preventing the second support rod 115 from detaching from the first support rod 113.

[0048] The first limiting part and the second limiting part can cooperate to form a limiting structure.

[0049] The first support rod 113 and the second support rod 115 can also be limited by other limiting structures. The above is only an example for the purpose of understanding.

[0050] In some embodiments, both the first support rod 113 and the second support rod 115 can be rigid support rods, which helps to reduce the friction between the second support rod 115 and the first support rod 113, making it easier for the second support rod 115 to move more smoothly on the first support rod 113, and making it easier for the second support rod 115 to move more smoothly under the action of gravity when the submersible hull rises, so that the first support rod 113 can retract into the second channel 1151.

[0051] As an example, both the first support rod 113 and the second support rod 115 can be metal supports, such as stainless steel supports or other metal supports.

[0052] In some embodiments, the inner wall of the second channel 1151 may be provided with a first guide portion, and the outer wall of the first support rod 113 may be provided with a second guide portion. Both the first guide portion and the second guide portion may extend along the length direction X.

[0053] One of the first guide portion and the second guide portion can be a guide groove, and the other can be a guide slide. The guide slide is at least partially movably inserted into the guide groove, thereby providing guidance for the movement of the second support rod 115. Furthermore, the cooperation between the guide groove and the guide slide can also prevent the second support rod 115 from rotating relative to the first support rod 113, which helps to reduce the impact on the first communication line 170.

[0054] As an example, the guide groove may include a groove opening, a first groove wall, a second groove wall, and a groove bottom wall, all of which extend along the length direction X. The groove bottom wall may be spaced apart from the groove opening, and both the first and second groove walls extend from the groove opening to the groove bottom wall. The guide slider passes through the groove opening portion within the guide groove and is at least slidably in contact with the first and second groove walls, thereby restricting the rotation of the guide slider to limit the rotation of the second support rod 115 relative to the first support rod 113.

[0055] In some embodiments, the buoyancy member 130 may have a cavity 131 inside to increase the buoyancy of the buoyancy member 130 in water.

[0056] The cavity 131 can be connected to the installation channel 111. The first communication line 170 can be partially located in the cavity 131. A portion of the first communication line 170 can be reserved in the cavity 131, which helps to prevent the first communication line 170 from being pulled when the second support rod 115 moves relative to the first support rod 113.

[0057] It should be noted that a sealed connection can be used between the first mounting part 1153 and the buoyancy component 130 to prevent water from entering the cavity 131.

[0058] As an example, the first mounting part 1153 and the buoyancy member 130 can be sealed by adhesive, by a sealing ring, or by other means.

[0059] In some embodiments, the buoyancy member 130 may be spherically shaped, which helps to make the buoyancy member 130 more uniform in water.

[0060] In some embodiments, the buoyancy member 130 may be a foam buoyancy member to increase the buoyancy of the buoyancy member on the water. For example, the buoyancy member 130 may be a polyethylene buoyancy member, a polyurethane buoyancy member, a polystyrene buoyancy member, a polyvinyl chloride buoyancy member, or other foam buoyancy members.

[0061] In some other embodiments, the buoyancy member 130 may also be a plastic buoyancy member capable of floating on water.

[0062] In some embodiments, the positioning buoy 100 may further include a mounting base 190, which may include a second hinge and a second mounting portion.

[0063] The second mounting part is used to install on the outside of the submarine hull to fix the mounting seat 190 to the submarine hull. The second mounting part and the submarine hull can be connected and fixed by means of adhesive, snap-fit, or fasteners.

[0064] As an example, the second mounting part may have a first mounting hole, and the outer side of the diving hull may have a second mounting hole opposite to the first mounting hole. The diving equipment may also include a fastener that can be inserted into the first and second mounting holes to fix the mounting base 190 to the diving hull. The fastener may be a screw, bolt, or pneumatic fastener.

[0065] The first hinge part 1133 is hinged to the second hinge part via a hinge shaft, so that the connecting rod 110 can rotate around the axis of the hinge shaft. This controls the connecting rod 110 to rotate only around the axis of the hinge shaft, thereby limiting the degree of freedom of the connecting rod 110 to reduce the swaying of the positioning buoy 100.

[0066] In some embodiments, the axial direction of the hinge shaft may be perpendicular to the length direction X of the connecting rod 110.

[0067] In some embodiments, the positioning buoy 100 may further include a positioning seat 210, which can be used to install on the outside of the hull of the submarine. The connection method between the positioning seat 210 and the submarine hull can refer to the connection method between the mounting seat 190 and the submarine hull, and will not be described again.

[0068] The positioning seat 210 may be provided with a positioning groove 211, the positioning groove 211 having an open slot 2111 located on the rotation path of the connecting rod 110, and the connecting rod 110 can be inserted into the positioning groove 2111 through the slot 2111 under the action of gravity (e.g., Figure 2 As shown in the figure, when the diving equipment is not submerged (for example, when the diving equipment is floating on the water or on land), the connecting rod 110 can automatically engage with the positioning slot 211 under the action of gravity to fix the position of the positioning buoy 100 without manual operation, making it more convenient to use.

[0069] The connecting rod 110 can also disengage from the positioning groove 211 through the slot 2111 under the buoyancy of the buoyancy component 130 (e.g., Figure 3 As shown in the figure, when the diving equipment is submerged, the buoyancy component 130 floats up under the buoyancy of the water, thereby driving the connecting rod 110 to automatically disengage from the positioning slot 211 through the slot 2111. No manual operation is required, which further simplifies the use of the positioning buoy 100.

[0070] As an example, when the diving equipment is not submerged, the connecting rod 110 can rotate towards the positioning seat 210 under the action of gravity. Under the action of gravity of the connecting rod 110, the second support rod 115 can be inserted into the positioning slot 211 through the slot 2111. When the diving equipment is submerged, the buoyancy component 130 floats up under the action of buoyancy of the water, so as to drive the second support rod 115 to automatically disengage from the positioning slot 211 through the slot 2111.

[0071] In some embodiments, the positioning buoy 100 may further include an AIS (Automatic Identification System) antenna and a second communication line 250.

[0072] The AIS antenna 230 can continuously receive signals transmitted from surrounding ships or shore-based base stations. These signals include ship identification information (such as ship name, call sign, Maritime Mobile Service Identity (MMSI)), location information (latitude and longitude), heading, speed, and other data. Furthermore, the AIS antenna 230 can also encode relevant information about the diving equipment into signals according to the AIS protocol and transmit them for reception by other ships or shore-based base stations. The specific working principle of AIS can be found in existing technologies and will not be elaborated further.

[0073] The AIS antenna 230 can be connected to the buoyancy member 130 and partially exposed outside the buoyancy member 130 to facilitate signal reception and transmission.

[0074] The second communication line 250 can extend through the mounting channel 111, with one end connected to the AIS antenna 230 and the other end exposed outside the mounting channel 111 for connecting to the communication module to transmit signals to the communication module. The configuration of the second communication line 250 can refer to that of the first communication line 170, and will not be described again.

[0075] In the positioning buoy 100 and diving equipment provided in this application embodiment, the first hinge portion 1133 at one end of the connecting rod 110 is configured to be hinged to the outside of the diving vessel hull, and the first mounting portion 1153 at the other end is equipped with a buoyancy member 130 that can float on the water surface. A Beidou antenna 150 is connected to the buoyancy member 130 and partially exposed outside the buoyancy member 130. A first communication line 170 extends through the mounting channel 111, with one end connected to the Beidou antenna 150 and the other end exposed outside the mounting channel 111 for connecting to a communication module. This allows the positioning buoy 100 to be applied to the diving equipment. In this case, when the submersible hull is submerged, the buoyancy component 130 can drive the connecting rod 110 to rotate relative to the submersible hull under the buoyancy of the water, so that the buoyancy component 130 and the Beidou antenna 150 can float on the water surface, so that the Beidou antenna 150 can communicate with the Beidou satellite. The first communication line 170 can transmit communication signals to the communication module to provide navigation and positioning information for the submersible hull. Compared with the underwater positioning technology in related technologies, the positioning buoy 100 provided in this application embodiment can achieve underwater positioning through the Beidou antenna 150, and the overall structure is simpler and the manufacturing cost is lower.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
