Description

Technical Field

[0001] The present application relates to the technical field of submarine external storage compartments, and in particular to a submarine external storage compartment connection device. Background Art

[0002] Submarines, also known as submersible vessels, are ships that can operate underwater. Submarines come in many types and shapes, ranging from small civilian submersible detectors that are fully automatic or operated by one or two people and have an operating time of several hours, to large nuclear submarines that can carry hundreds of people and remain submerged for 3-6 months.

[0003] Existing submarines are designed with a variety of working cabins to provide guarantees for the operation of the submarine. In this way, the space left for personnel activities inside the submarine is very limited. Personnel living in it for a long time will feel a huge sense of oppression, which is not conducive to personnel operating the submarine. Some equipment cabins do not need to be set up inside the submarine and can be used, such as reserve buoyancy compartments, reserve battery compartments, and life-saving compartments. The equipment in these cabins can be stored in external compartments outside the submarine for use. On the one hand, it saves the internal space of the submarine and facilitates personnel activities. On the other hand, it is also convenient to remove it from the submarine for separate replacement and maintenance, thereby improving convenience.

[0004] The patent with the patent authorization announcement number CN106741768B discloses a miniature submarine external compartment separation device, including a main boat hull, multiple external compartments and an automatic line separation device. The automatic line separation device includes an automatic separation socket and an automatic separation plug. The automatic separation socket is arranged at the front end of the main boat hull. A main slot is arranged in the automatic separation socket. An electric docking screw B is movably arranged in the main slot. A line connection block is also arranged in the main slot. A plurality of line branch sockets are arranged on the outside of the line connection block. The plurality of line branch sockets are connected to internal cables. The line connection block is fixed to the bottom of the main slot by fixing screws. Sealing rings are arranged on the inside and outside of the line connection block. A plurality of line branch plugs are arranged on the automatic separation plug. The outer end of the electric docking screw B is arranged with a thread, and an electric docking screw hole is arranged in the automatic separation plug.

[0005] The external hanger connection device in the above application adopts an external structure connection. After the external hanger is connected to the submarine, the two cannot communicate with each other. Personnel cannot enter the external hanger from the submarine in the deep sea to carry out maintenance and operation, which reduces practicality.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figure 1-Figure 7 As shown, a submarine external compartment connection device proposed in one embodiment of the present application includes:

[0041] The submarine body 1 has a docking groove 101 at the bottom thereof, a docking chamber 2 connected to the docking groove 101 is installed in the submarine body 1, a connection port 201 is configured at the bottom of the docking chamber 2 and a seal cover 202 that can be opened and closed is arranged at the top. It should be noted that the docking chamber 2 is integrally installed at the inner bottom of the outer shell of the submarine body 1, the connection port 201 thereon is downwardly arranged and connected to the outside of the submarine body 1, and the seal cover 202 is used to isolate the docking chamber 2 from the inside of the submarine body 1 to prevent seawater from entering the submarine body 1;

[0042] The external warehouse body 3 is provided with an inlet and outlet 301, and a docking cover 4 for plugging into the connection port 201 is hinged inside the inlet and outlet 301. The size of the docking cover 4 is smaller than that of the connection port 201, and the docking cover 4 can be completely inserted into the connection port 201. The external warehouse body 3 can be a lifeboat or a storage buoyancy boat or other equipment boat that can be externally hung. The inlet and outlet 301 is arranged at the top and is used to connect with the connection port 201 of the docking warehouse 2;

[0043] The connector 5 includes a rotating telescopic head 501 installed on the docking cover 4, a snap-on ball 502 is constructed on the moving end of the rotating telescopic head 501, a transfer cover 503 for snapping the docking cover 4 is hinged in the connection port 201, and a limiting mechanism 6 for limiting the upward and downward movement of the snap-on ball 502 is installed on the transfer cover 503. It should be noted that the rotating telescopic head 501 can be telescopically operated. It is in an extended state in the initial state. When the external warehouse body 3 and the submarine body 1 need to be docked on the seabed, First, the card ball 502 needs to be inserted into the transfer cover 503. At this time, the docking cover 4 is directly below the transfer cover 503 and does not contact the transfer cover 503. Then, the card ball 502 is limited up and down by the limit mechanism 6. At this time, the telescopic head 501 is retracted. Because the position of the card ball 502 is limited, the external warehouse body 3 can be driven to automatically move toward the bottom of the submarine body 1 until it enters the docking groove 101. At this time, the docking cover 4 is completely attached to the bottom of the transfer cover 503.

[0044] The sealing assembly 7 includes a mounting ring 701 fixedly connected to the bottom of the docking chamber 2 and arranged around the outside of the connection port 201. A sealing ring 702 for rotatably engaging with the mounting ring 701 is rotatably installed on the external chamber body 3. The external chamber body 3 in the docking state forms a fit with the bottom of the submarine body 1. At this time, the sealing ring 702 will be tightly fitted and docked with the mounting ring 701. The connection and fixation of the two can be achieved by rotating the sealing ring 702, so that the docking cover 4 and the transfer cover 503 are sealed and wrapped therein to form a sealed passage. By dehydrating the docking chamber 2, the docking chamber 2 can be connected with the inside of the external chamber body 3. Personnel can enter the inside of the external chamber body 3 by opening the sealing cover 202, the transfer cover 503 and the docking cover 4, which is convenient for personnel to repair and operate it, and increases convenience. Compared with the traditional external structure connection, the present application adopts an internal structure connection, which can be directly connected to the inside of the external chamber body 3 after connection in the sea, and the external chamber body 3 can be repaired and operated without personnel leaving the cabin, thereby increasing safety and convenience.

[0045] like Figure 5-Figure 6As shown, in some embodiments, the docking bin 2 includes a vertical cylinder 203, a storage cylinder 204 is configured on one side of the vertical cylinder 203, a pressure-equalizing tube 205 is connected to the end of the storage cylinder 204, a flip limiter 8 is installed in the storage cylinder 204 for driving the transfer cover 503 to automatically flip and fix its position, wherein the vertical cylinder 203 is a pressure-equalizing space for balancing the internal and external pressures, and when the docking bin 2 is connected and docked with the external bin body 3, the sealing cover 202 is always sealed at the top of the vertical cylinder 203, and the transfer cover 503 needs to be opened first, and the sealing cover 202 is sealed at the top of the vertical cylinder 203. The pressure between the transfer cover 503 and the docking cover 4 is released to the inside of the vertical cylinder 203, that is, in order to synchronize the pressure between the mounting ring 701 and the sealing ring 702, the pressure in the docking chamber 2 is different from the pressure in the submarine body 1. It is necessary to use the equalizing pipe 205 to pump out the excess seawater and inject air. At this time, the pressure in the submarine body 1 is balanced with the pressure in the vertical cylinder 203. On the one hand, the sealing cover 202 and the docking cover 4 can be opened more easily. On the other hand, it can prevent injuries to personnel due to excessive pressure, thereby increasing safety.

[0046] like Figure 8 As shown, in some embodiments, the flip limiter 8 includes a connecting rod 801 rotatably installed on both sides of the storage cylinder 204, the other end of the connecting rod 801 is hinged with a connecting rod 802, the other end of the connecting rod 802 is hinged on both sides of the transfer cover 503, and a rotating motor 803 with an output shaft fixedly connected to one end of the connecting rod 801 is installed on the outside of the storage cylinder 204, a wedge block 804 is constructed on the inside of the storage cylinder 204, a wedge groove 5031 for sleeve-fitting the wedge block 804 is constructed on the edge of the upper surface of the transfer cover 503, two positioning grooves 5032 arranged opposite to each other are constructed on the outside of the transfer cover 503, and a spring plug column 9 for connecting the positioning groove 5032 is installed in the vertical cylinder 203 It should be noted that the spring plug 9 is used to fix the transfer cover 503 in a sealed state. When the docking is completed, the spring plug 9 can be retracted to disengage from the positioning groove 5032, and then the rotating motor 803 is used to drive the connecting rod 1 801 to rotate, and then the connecting rod 2 802 is used to drive the transfer cover 503 to flip to a vertical state. At this time, the wedge groove 5031 on the transfer cover 503 will be sleeved on the wedge block 804, and the internal opening of the wedge groove 5031 is larger than the wedge block 804, and the wedge block 804 has a certain elastic force. When the two are plugged into each other, they can play a certain limiting role. With the self-locking of the rotating motor 803, the transfer cover 503 can be prevented from falling back easily, thereby increasing safety.

[0047] like Figure 8-Figure 10As shown, in some embodiments, the spring plug-in column 9 includes a horizontal frame 901 fixedly connected to the inner wall of the vertical tube 203, and a plug-in column 902 that is plugged into the positioning groove 5032 is horizontally slidably installed at one end of the horizontal frame 901, and a support spring 903 is connected between the other end of the horizontal frame 901 and the plug-in column 902, and an electromagnet 904 that penetrates the support spring 903 and is arranged opposite to the plug-in column 902 is fixedly connected in the horizontal frame 901. In the initial state, the plug-in column 902 is in a pop-up state. At this time, the electromagnet 904 is not energized. The plug-in column 902 can be pushed into the positioning groove 5032 by utilizing the elastic force of the support spring 903, so as to limit the position of the transfer cover 503 to prevent seawater from entering. After the docking is completed, the electromagnet 904 can be used to attract the plug-in column 902 to disengage from the positioning groove 5032, so that the transfer cover 503 can be flipped after being disengaged from the limit, and the automatic fixing and separation are performed without manual operation, thereby increasing the convenience and safety of the device.

[0048] like Figure 7 As shown, in some embodiments, the docking cover 4 includes a conical top cover 401 and an arc-shaped bottom cover 402 that are interlocked, and the rotating telescopic head 501 includes a rotating rod 5011 rotatably installed in the arc-shaped bottom cover 402. A screw tube 5012 is installed through the top thread of the conical top cover 401. The upper end of the rotating rod 5011 is fixedly connected to a polygonal column 5013 slidably inserted at the bottom of the screw tube 5012, and the clamping ball 502 is fixedly connected to the upper end of the screw tube 5012. It should be noted that a driving structure is provided in the arc-shaped bottom cover 402 for controlling the rotating rod The rotation of 5011 mainly includes a control motor and two driving gears, one of which is connected to the output shaft of the control motor, and the other is connected to the rotating rod 5011. The motor is used to automatically control the rotation of the rotating rod 5011, thereby driving the screw tube 5012 to rotate synchronously through the polygonal column 5013, so as to realize the threaded cooperation between the screw tube 5012 and the conical top cover 401, and then control the telescopic operation of the screw tube 5012 relative to the conical top cover 401, so as to pull the external storage body 3 close to the submarine body 1.

[0049] like Figure 6-Figure 9As shown, in some embodiments, the transfer cover 503 includes a column frame 5033, the bottom of the column frame 5033 is configured with a conical groove 5034 for wrapping the conical top cover 401, the top of the conical groove 5034 is configured with a cylindrical groove 5035 for movably plugging the card receiving ball 502, the top of the cylindrical groove 5035 is configured with a positioning cone block 5036, the card receiving ball 502 includes a sphere 5021 fixedly connected to the upper end of the screw tube 5012, the top of the sphere 5021 is configured with a conical groove 5022 plugged with the positioning cone block 5036, and the sphere The circumferential side array structure 5021 has four clamping blocks 5023. It should be noted that the bottom of the column frame 5033 is set as a conical groove 5034, which can facilitate the clamping ball 502 to contact its inclined surface and smoothly enter the cylindrical groove 5035, playing a guiding and positioning role. When the clamping ball 502 is inserted into the cylindrical groove 5035, the conical groove 5022 will first contact the positioning cone block 5036, so as to calibrate the axial position of the screw tube 5012, so that the limiting mechanism 6 can smoothly limit the clamping ball 502.

[0050] like Figure 8-Figure 12 As shown, in some embodiments, the limiting mechanism 6 includes four arc plates 601 horizontally slidably installed in the column frame 5033, the four arc plates 601 are arranged in an array along the circumference of the cylindrical groove 5035 and the concave ends are all arranged toward the axis of the cylindrical groove 5035, a rotating ring 602 is rotatably installed in the column frame 5033, and a flat thread 603 is configured on the rotating ring 602 to engage with the thread of the arc plate 601. When the ball 5021 enters the cylindrical groove 5035, the block 5023 thereon will be above the arc plate 601. At this time, the arc plate 601 is completely inside the column frame 5033, and the rotating ring 602 is rotated. 02 can make the rotating ring 602 and the arc plate 601 threadedly cooperate, thereby driving the arc plate 601 to penetrate the inner wall of the column frame 5033 and move toward the axis of the cylindrical groove 5035 until the ends of the four arc plates 601 are connected to form a ring. At this time, the arc plate 601 abuts against the surface of the sphere 5021, which can limit the block 5023 to prevent the card-connecting ball 502 from detaching, but does not affect the rotation of the card-connecting ball 502. When the screw tube 5012 rotates, it can be threadedly cooperated with the conical top cover 401, thereby driving the external storage body 3 to continuously approach the submarine body 1 until the two are completely fitted.

[0051] like Figure 8-Figure 12As shown, in some embodiments, two L-shaped toggle rods 6021 are arranged opposite to each other and movably penetrate the inner wall of the cylindrical groove 5035, and the vertical sections of the two L-shaped toggle rods 6021 are arranged between the four blocks 5023. A movable space for the block 5023 to rotate is constructed between the ends of the vertical sections of the L-shaped toggle rods 6021 and the upper surface of the arc plate 601. It should be noted that the bottom end of the L-shaped toggle rod 6021 is provided with a The L-shaped push rod 6021 is provided with an oblique angle for misalignment with the block 5023. When the conical groove 5022 on the clamping ball 502 is sleeved on the positioning cone block 5036, the vertical section of the L-shaped push rod 6021 is completely between the two clamping blocks 5023. When the clamping ball 502 rotates, the clamping block 5023 will resist the L-shaped push rod 6021 and rotate synchronously, thereby driving the rotating ring 602 to rotate, so as to drive the arc plate 601 to protrude and move. When the ends of the lever 5020 are in contact with each other, the rotation of the screw tube 5012 will produce a threaded fit with the conical top cover 401. Therefore, the locking ball 502 will move downward with the screw tube 5012 during the rotation until it contacts the arc plate 601. At this time, the locking block 5023 is below the end of the vertical section of the L-shaped toggle rod 6021 and is misaligned with the bevel. At this time, the locking ball 502 will rotate again to continuously drive the L-shaped toggle rod 6021 to rotate. The above operation is the process during docking. When it is necessary to flip the docking cover 4 downward to open and flip the transfer cover 503 upward to open, the rotation of the screw tube 5012 can be used to push the locking ball 502 to move up and reverse at the same time, so as to drive the L-shaped toggle rod 6021 and the swivel 602 to rotate in the opposite direction, thereby retracting the arc plate 601 to facilitate the separation of the docking cover 4 and the transfer cover 503. The operation is convenient and no additional driving force is required, thereby increasing the linkage.

[0052] like Figure 7 and Fig.13 As shown, in some embodiments, a plurality of strip arc grooves 7011 are constructed along a circumferential array at the bottom of the mounting ring 701, a plurality of connecting columns 7021 are constructed along a circumferential array on the upper side of the sealing ring 702, a connecting ball 7022 is constructed at the top of the connecting column 7021, a notch 7012 for plugging the connecting ball 7022 is constructed at one end of the strip arc groove 7011, the longitudinal section of the strip arc groove 7011 is T-shaped, and a driving member 10 for driving the sealing ring 702 to rotate is installed in the external hanging warehouse 3. When the external hanging warehouse 3 and the submarine body 1 are fitted together, the mounting ring 701 and the sealing ring 702 are also fitted together. At this time, the connecting ball 7022 will be inserted into the notch 7012 of the strip arc groove 7011, and the driving member 10 is used to drive the sealing ring 702 to rotate, so that the connecting column 7021 is moved along the strip arc groove 7011 with the T-shaped section, so as to limit and fix it to achieve a sealing operation.

[0053] like Figure 7As shown, in some embodiments, the driving member 10 includes a rack 7023 constructed at the bottom of the sealing ring 702, a driving motor 1001 is fixedly connected to the external storage body 3, and a transmission gear 1002 meshing with the rack 7023 is fixedly connected to the output shaft of the driving motor 1001. Two relatively arranged clamping plates 7024 are constructed on the inner side of the sealing ring 702, and two separation grooves 403 for the clamping plates 7024 to movably penetrate the edge of the docking cover 4 are constructed. It should be noted that the clamping plates 7024 are not aligned with the separation grooves 403 in the initial state. At this time, the snap-in plate 7024 is at the bottom of the docking cover 4, which is used to limit the docking cover 4 and maintain the sealing state of the external storage body 3. When the device is docked and connected, when the docking cover 4 needs to be opened, the driving motor 1001 can be used to drive the sealing ring 702 to rotate and drive the snap-in plate 7024 to dock with the separation groove 403, so that the snap-in plate 7024 can smoothly cross the separation groove 403. A single driving unit can simultaneously control the opening and closing of the docking cover 4 and the connection operation of the sealing ring 702, thereby increasing the linkage of the device.
