Description

Technical Field

[0001] The utility model belongs to the technical field of ocean detection, and in particular relates to a timing communication buoy based on a detachable watertight connector communication. Background Art

[0002] Submerged buoys are essential equipment for fixed-point, continuous, and long-term observation of the marine environment. These include self-contained buoys, real-time communication buoys, and timed communication buoys. Timed communication buoys offer the strongest anti-salvage capabilities, long lifespan, and high reliability. The timed communication buoy, installed on the timed communication buoy, rises to the surface under its own positive buoyancy at a preset time, completing observation data transmission. This is a crucial component of the timed communication buoy.

[0003] The timing communication buoy usually transmits data with the submerged buoy main control system through a watertight cable. After the data transmission is completed, it is necessary to disconnect the physical connection of the cable between the timing communication buoy and the submerged buoy main control system, and float the timing communication buoy out of the water.

[0004] A common solution currently involves severing the watertight cable, such as the buoy release scheme disclosed in the patent "A Communication Buoy Release Mechanism" (Patent Application No.: 202311661397.4). This scheme uses high-pressure gas generated by an ignition device to rapidly move a cutter to sever the watertight cable. The timing communication buoy is positively buoyant in the water, and the cutter shaft and a limit pressure rod are used to restrain its upward buoyancy. After the cutter moves forward, the restraint is released, and the timing communication buoy rises out of the water under the action of its own positive buoyancy, thus completing the cable severing and buoy release functions.

[0005] However, this method has the following problems: 1. It is expensive and has a high risk of gunpowder explosion. Its use needs to be regulated and cannot be promoted and applied on a large scale. 2. The watertight cable cannot be reused after being cut. The cable needs to be replaced for each test, which further increases the cost of use. 3. There is no reliable fixation between the timing communication buoy and the submerged buoy. It only relies on the pressure rod and cutter shaft of the buoy release mechanism to limit its floating. Collision and other problems may occur during underwater work. Utility Model Content

[0046] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described 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 making any creative efforts are within the scope of protection of the present invention.

[0048] The terms "first," "second," and "third" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0049] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0050] like Figures 1 to 5 As shown, in an illustrative embodiment of a timing communication buoy based on a removable watertight connector communication of the present invention, the timing communication buoy based on a removable watertight connector communication includes a fixed frame 1, a buoy body 2, a release mechanism 3, a compression spring 4 and a quick-release connector assembly 5.

[0051] The fixed frame 1 is fixedly installed underwater, and the release mechanism 3 is installed on the fixed frame 1. The release mechanism 3 has a motor 31 and a screw 32. The screw 32 is coaxially connected to the output shaft of the motor 31. The screw 32 is threadedly connected to the threaded hole 21 set in the buoy body 2, thereby fixing the buoy body 2 on the fixed frame 1. The threaded hole 21 is a countersunk hole and does not pass through the shell of the buoy body 2, ensuring the waterproof performance of the buoy body 2. The compression spring 4 is installed between the buoy body 2 and the fixed frame 1 and is clamped by the two in a compressed state. The quick-release connector assembly 5 is installed on the fixed frame 1 and connected to the buoy body 2, including a watertight plug 51 and a watertight socket 52. The watertight plug 51 is connected to the fixed frame 1, and the watertight socket 52 is fixedly installed on the buoy body 2 and plugged into the watertight plug 51. The limit member 22 set on the buoy body 2 is slidably installed in the limit guide groove 11 axially set on the fixed frame 1.

[0052] The watertight plug 51 is electrically connected to the submerged buoy main control system via a cable 59, and the watertight socket 52 is electrically connected to the electrical components within the buoy body 2. By plugging the watertight plug 51 into the watertight socket 52, the electrical connection between the submerged buoy main control system and the buoy body 2 is achieved, allowing the submerged buoy main control system to upload data to the buoy body 2. After the submerged buoy main control system completes the data transmission to the buoy body 2, the buoy body 2 needs to be floated to the surface so that it can be recovered and the observation data collection can be completed.

[0053] The motor 31 drives the screw 32 to rotate, and the limit member 22 limits the circumferential direction of the buoy body 2 by cooperating with the limit guide groove 11. The buoy body 2 will not rotate with the screw 32. The screw 32 gradually unscrews axially from the threaded hole 21 and pushes the buoy body 2 to move axially. The limit member 22 slides axially in the limit guide groove 11 along with the buoy body 2. When the screw 32 is completely out of the threaded hole 21, the limit member 22 is out of the limit guide groove 11, and the buoy body 2 is separated from its fixed connection. The compression spring 4 loses its clamping restraint and releases the elastic force to further push the buoy body 2 to move axially upward, away from the fixed frame 1. As the buoy body 2 gradually moves axially away from the fixed frame 1, the watertight socket 52 moves synchronously with the buoy body 2 to pull out the watertight plug 51, disconnecting the line connection between the buoy body 2 and the fixed frame 1. After the fixed connection and line connection between the buoy body 2 and the fixed frame 1 are disconnected, the buoy body 2 loses its restraint and floats to the water surface, realizing the release and floating of the buoy body 2.

[0054] In the exemplary embodiment described above, the timing communication buoy, which utilizes a removable watertight connector for communication, achieves both fixed connection and communication between the buoy body 2 and the fixed frame 1 through a removable threaded connection between the screw 32 and the threaded hole 21, and a removable plug-in connection between the watertight plug 51 and the watertight socket 52. The threaded connection exhibits self-locking properties, and the engagement of the stopper 22 with the stopper guide groove 11 limits the rotation of the buoy body 2, thereby maintaining a stable threaded connection when the thread is stationary and allowing the buoy body 2 to remain stably underwater. Compared to magnetic or wireless connections, the plug-in connection not only ensures efficient data transmission but also a stable communication connection, enabling the submerged buoy master control system to stably and efficiently transmit observation data to the buoy body 2. The motor 31 drives the screw 32 out of the threaded hole 21, causing the buoy body 2 to move axially away from the fixed frame 1, thereby disconnecting both the fixed connection and the communication connection. The strong and stable driving force ensures that the buoy body 2 can move under the drive of the screw 32 even in the event of adhesion by underwater organisms. During the process of screw rod 32 being screwed out of threaded hole 21, limit member 22 moves axially along limit guide groove 11 and finally comes out. The cooperation between limit member 22 and limit guide groove 11 prevents buoy body 2 from rotating synchronously with screw rod 32, ensuring that screw rod 32 can be screwed out of threaded hole 21. After the threaded connection between threaded hole 21 and screw rod 32 is disconnected, compression spring 4 loses the constraint of buoy body 2, and its elastic force pushes buoy body 2 to move further, accelerating the speed and distance of buoy body 2 to disengage, and the elastic force acts as a thrust on buoy body 2, causing buoy body 2 to further pull watertight socket 52, thereby ensuring that watertight socket 52 is completely pulled out of watertight plug 51, ensuring the disconnection of wired communication connection, and allowing buoy body 2 to be released and floated stably and efficiently. The threaded connection and plug-in connection methods realize fixed connection and communication connection, have strong connection reliability, simple structure and low cost, and both methods can be installed and connected again and can be reused, which solves the problems of high cost, high risk, non-reusability and insufficient connection reliability of the current method of cutting off the physical connection for floating of the timing communication buoy.

[0055] In order to ensure that when the compression spring 4 releases the elastic force, the elastic force remains in the axial direction, the buoy body 2 can be pushed away from the fixed frame 1 to the greatest extent, thereby ensuring the disconnection of the limited communication connection. The fixed frame 1 has a guide seat 12. When the buoy body 2 and the fixed frame 1 clamp the compression spring 4 in a compressed state, the compression spring 4 is sleeved on the guide seat 12, and the guide seat 12 is in the axial direction, so that it guides the release deformation of the compression spring 4.

[0056] In some embodiments, as Figures 3 and 4As shown, the quick-release connector assembly 5 further includes a locking sleeve 53. One end of the locking sleeve 53 is sleeved onto the watertight plug 51 and fixedly connected thereto. The other end of the locking sleeve 53 is sleeved onto the watertight socket 52. The locking sleeve 53 has a snap-fit ​​groove 54 formed on its inner wall. A raised ring 55 formed on the outer wall of the watertight socket 52 snaps into the snap-fit ​​groove 54.

[0057] The locking sleeve 53 encloses the connection between the watertight plug 51 and the watertight socket 52, further improving the waterproof performance of the wired communication connection. In addition, the locking connection between the raised ring 55 and the locking groove 54 improves the stability of the plug-in connection of the watertight socket 52 on the watertight plug 51, ensuring the stability of the wired communication connection.

[0058] When the buoy body 2 is released, the screw 32 is unscrewed out of the threaded hole 21 under the drive of the motor 31, and the compression spring 4 is released and pushes the buoy body 2 away from the fixed frame 1, so that the buoy body 2 pulls the watertight socket 52, thereby pulling the raised ring 55 out of the snap-in groove 54, disconnecting the snap-in connection, and pulling the watertight socket 52 out of the watertight plug 51, ensuring the disconnection of the wired communication connection. The push of the compression spring 4 ensures that the buoy body 2 has sufficient pulling force to disconnect the snap-in connection, while improving the stability of the wired communication connection, ensuring that the wired communication connection can be stably disconnected when released. In order to ensure the smooth disconnection of the snap-in connection, the locking sleeve 53 is made of plastic, so that it has a certain deformation space, so that when the raised ring 55 is disengaged, the locking sleeve 53 is pushed radially outward, and the raised ring 55 can be removed from the inner wall of the locking sleeve 53.

[0059] In some embodiments, the surface of the raised ring 55 is arc-shaped and mates with the inner wall of the snap-fit ​​groove 54. During the snap-fit ​​connection, the surface of the raised ring 55 fully contacts the inner wall of the snap-fit ​​groove 54, ensuring a stable connection. The arc-shaped surface of the raised ring 55 allows it to smoothly disengage from the snap-fit ​​groove 54 when pulled, ensuring a smooth snap-fit ​​disconnection and preventing the raised ring 55 from becoming stuck in the snap-fit ​​groove 54 and causing problems such as breaking the watertight socket 52.

[0060] In some embodiments, a stepped groove 56 is provided on the inner wall of one end of the locking sleeve 53, and the engaging groove 54 is provided on the inner wall of the stepped groove 56. The locking sleeve 53 is provided with the stepped groove 56, and the end of the watertight socket 52 is provided with a corresponding stepped structure. Therefore, when the watertight socket 52 is inserted into the locking sleeve 53 and plugged into the watertight plug 51, the stepped groove 56 of the locking sleeve 53 aligns with the stepped structure of the watertight socket 52 to limit axial movement. Therefore, when the watertight socket 52 is inserted and cannot move further, it is ensured that the watertight socket 52 is fully inserted into the watertight plug 51 and the raised ring 55 is engaged in the engaging groove 54, achieving accurate positioning and connection. It also prevents the watertight socket 52 from being over-inserted, causing the raised ring 55 to fall out of the engaging groove 54 again after being engaged, and pushing the locking sleeve 53 radially outward for a long time, causing it to be deformed and damaged. In addition, the provision of the step groove 56 makes the thickness of this end of the locking sleeve 53 thinner, so that when the raised ring 55 escapes from the engaging groove 54, the engaging groove 54 is more likely to deform radially outward, thereby preventing the locking sleeve 53 from being too strong to deform radially, resulting in the raised ring 55 being unable to escape from the engaging groove 54.

[0061] In some embodiments, the watertight plug 51 is provided with a metal flange 57 and is sleeved with a mounting plate 58. The mounting plate 58 is fixed to the fixed frame 1 by bolts and presses the metal flange 57 to the fixed frame 1. The press-fit installation improves the stability of the fixed installation of the watertight plug 51 and also facilitates disassembly.

[0062] In some embodiments, the watertight plug 51 can also adopt a more flexible connection method. The watertight plug 51 is connected to a cable 59, which is fixed on the fixed frame 1 and connected to the submersible buoy main control system, so that the submersible buoy main control system can transmit the observation data to the watertight plug 51.

[0063] When the watertight plug 51 is in contact with the fixed frame 1 and the screw 32 is threadedly engaged with the threaded hole 21, the buoy body 2 is fixed to the fixed frame 1, and the watertight socket 52 presses and fixes the watertight plug 51 to the fixed frame 1. At this time, the cable 59 is in a relaxed state, and the length of the cable 59 is greater than the shortest connection length between the watertight plug 51 and the submerged buoy main control system.

[0064] When the buoy body 2 is released, the watertight socket 52 moves away from the fixed frame 1 along with the buoy body 2, thereby eliminating the pressure on the watertight plug 51. Since the two remain plugged in, the watertight plug 51 is pulled out of the fixed frame 1 by the watertight socket 52. When the watertight socket 52 is pulled out until the cable 59 is tightened, it cannot move further away from the fixed frame 1. The watertight socket 52 then moves further along with the buoy body 2, thereby being unplugged from the watertight plug 51 and disconnecting the wired communication connection. In addition, in the process of the watertight socket 52 pulling the watertight plug 51 out of the fixed frame 1, the buoy body 2 gradually accelerates to float up, and the movement speed of the connected watertight socket 52 and watertight plug 51 is accelerated accordingly. When the cable 59 is tightened, the movement speed of the watertight plug 51 is rapidly reduced, and the cable 59 exerts a strong pulling effect on the watertight plug 51. At the same time, the buoy body 2 also exerts a pulling effect on the watertight socket 52. The two opposite pulling forces act together on the connection between the watertight socket 52 and the watertight plug 51, thereby quickly disconnecting the plug-in connection between the two, ensuring that the wired communication connection can be disconnected when released.

[0065] When the cable 59 is pulled out from the fixing frame 1 and tightened, the watertight socket 52 is pulled out from the watertight plug 51 .

[0066] In some embodiments, as Figure 5 As shown, the release mechanism 3 further includes a housing 33, within which the motor 31 is mounted. A screw 32 extends through a transmission hole 34 provided in the housing 33. One end of the screw 32 extends into the housing 33 and is connected to the output shaft of the motor 31 via a coupling 6. The other end of the screw 32 extends out of the housing 33 and is threadedly engaged with the threaded hole 21. A thrust bearing 7 is sleeved and mounted on the screw 32. The thrust bearing 7 is retained in a countersunk hole provided at the inner end of the transmission hole 34 by a retaining nut 8 fixedly mounted on the screw 32.

[0067] The motor 31 is installed in a sealed cabin 33. The sealing performance of the cabin 33 is used to ensure that the motor 31 is in a dry environment. This allows the motor 31 to maintain stable operation without the need for a waterproof motor 31, thereby reducing equipment costs. The thrust bearing 7 ensures the smooth rotation of the screw 32, and the limiting nut 8 installed at its inner end is used to achieve the limited installation of the thrust bearing 7, simplifying the fixing structure, improving the compactness of the assembly structure, and reducing the weight of the equipment. In order to ensure the sealing of the cabin 33, a plurality of sealing rings 9 are provided on the screw 32, and the sealing rings are all located in the transmission hole 34. In order to facilitate installation and processing, the cabin 33 has ports at both ends, and end covers 35 are installed on the ports for sealing. The cabin 33 can be opened or closed by disassembling the end cover 35, thereby realizing the disassembly and assembly of the internal components.

[0068] In some embodiments, a cylindrical stopper 36 is provided on the end surface of the chamber 33. The connecting seat 23 provided on the buoy body 2 is inserted into the stopper 36. The screw 32 extends into the stopper 36 and is threadedly connected to the threaded hole 21 on the connecting seat 23. When the screw 32 is threadedly connected to the threaded hole 21, the connecting seat 23 is inserted into the stopper 36, thereby sealing the transmission hole 34 communicating with the stopper 36. This improves the sealing performance of the chamber 33 when the buoy body 2 is fixedly connected to the fixed frame 1.

[0069] In some embodiments, the stopper 22 is disposed on the outer wall of the connecting base 23, and the stopper guide 11 is disposed on the inner wall of the stopper base 36. The stopper base 36 is secured with bolts and is removable. The stopper guide 11 is disposed on the stopper base 36, facilitating independent processing and slotting of the housing 33. Furthermore, the stopper 22 and the stopper guide 11 are nested within each other, not only enhancing the compactness of the structure but also preventing damage from external structures.

[0070] In some embodiments, the connector 23 and the retaining seat 36 form an interference fit, with the end surface of the connector 23 abutting the surface of the fixed frame 1. This further enhances the tightness of the gaps between the connector 23 and the retaining seat 36, as well as the gaps between the connector 23 and the fixed frame 1, improving waterproof performance. Furthermore, when the thread is unscrewed from the threaded hole 21, the thread drive generates sufficient driving force to overcome the friction caused by the interference fit and push the connector 23 out of the retaining seat 36, ensuring the release and buoyancy of the buoy body 2.

[0071] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0072] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
