Technical Field

[0001] This invention relates to the field of dynamic submarine cable technology, and in particular to a dynamic cable guide quick connection device and a dynamic cable guide. Background Technology

[0002] Currently, in pilot floating wind turbine power generation projects in China, the cable-machine (cable and turbine) connection is permanent. During construction and installation, divers need to dive underwater, and tightening dozens of bolts is required to install flanges, making construction extremely inconvenient. Furthermore, during the service life, accidents or malfunctions may occur between the cable and the floating wind turbine, requiring divers to dive underwater to dismantle the cable-machine connection, causing further inconvenience. Due to the harsh working environment of floating wind farms, the underwater construction process for divers is cumbersome and high-risk. Summary of the Invention

[0003] This invention provides a dynamic cable quick connection device and a dynamic cable to solve the shortcomings of the prior art where the cable-machine is permanently connected, requiring divers to dive underwater for operation, which is cumbersome and risky.

[0004] The present invention provides a dynamic cable guide quick connection device, comprising: a male connector, a female connector, and a traction component.

[0005] The outer wall of the male connector is provided with a locking groove along the circumference, and both ends of the female connector are provided with openings. The outer wall of the female connector is provided with multiple locking units spaced apart along the circumference, and each locking unit includes a locking component and a triggering component.

[0006] The locking assembly includes a telescopic drive, a rotating arm, a locking pin, and a tension spring. The telescopic drive is disposed on the outer wall of the connecting female head. The first end of the rotating arm abuts against the output end of the telescopic drive. The middle part of the rotating arm is rotatably connected to the outer wall of the connecting female head so that the rotating arm can swing in a first direction. The locking pin passes radially through the first sliding groove of the connecting female head and slides in cooperation with the first sliding groove. One end of the tension spring is connected to the connecting female head, and the other end of the tension spring is connected to the locking pin. The locking pin is connected to the rotating arm, and the connection point between the locking pin and the rotating arm is located on the side closer to the telescopic drive.

[0007] The triggering assembly includes a trigger plate, a locking fastener, a locking sleeve bracket, and a trigger pin. The trigger plate includes a main body and a first abutting part. The first abutting part is located at the first end of the main body. The trigger plate is connected to the second end of the rotating arm. The locking fastener is connected to the main body. The locking sleeve bracket is located on the outer wall of the connecting female head. The trigger pin passes through the second sliding groove of the connecting female head and slides in cooperation with the second sliding groove.

[0008] When the triggering component is not triggered, the locking element engages with the locking sleeve bracket, and the tension spring exerts a radially inward pulling force on the locking pin, causing the end face of the locking pin to be located within the first sliding groove.

[0009] When the triggering component is triggered, one end of the male connector abuts against the trigger pin, causing the locking member to disengage from the locking sleeve bracket, and causing the tension spring to pull the locking pin radially inward, so that the end face of the locking pin is located in the locking groove.

[0010] The traction member is detachably connected to the male connector, and the traction member is used to pull the male connector to move along the axial direction of the female connector.

[0012] The trigger plate further includes a second abutting portion, which is located at the second end of the main body and abuts against the pressing member.

[0013] According to the dynamic cable quick connection device provided by the present invention, the triggering component further includes a locking rod and a spring plunger. The spring plunger is connected to the main body, one end of the locking rod is connected to the spring plunger, and the other end of the locking rod is connected to the locking member.

[0014] According to the dynamic cable quick connection device provided by the present invention, the triggering component further includes a reset spring, the reset spring being sleeved on the trigger pin, one end of the reset spring being connected to the inner wall of the connecting female head, and the other end of the reset spring being connected to the trigger pin.

[0015] According to the dynamic cable quick connection device provided by the present invention, the connecting male is sleeved on the traction member, and the traction member can move along the axial direction of the connecting male.

[0016] The male connector is provided with multiple pre-fixing mechanisms at intervals along the circumference. Each pre-fixing mechanism includes a push shaft and a detachment component. The detachment component is connected to the inner end of the push shaft. The push shaft passes radially through the fourth slide groove of the male connector and slides in cooperation with the fourth slide groove. The inlet end of the female connector is provided with a flared pressure slope. The outer wall of the traction component is provided with a first groove along the circumference.

[0017] In the initial state, the detachable part is connected to the push shaft and located at a first position in the first groove. In the detached state, the detachable part is detached from the push shaft and located at a second position in the first groove.

[0018] According to the dynamic cable quick connection device provided by the present invention, the length of the detachment member is the same as the depth of the first groove.

[0019] According to the dynamic cable quick connection device provided by the present invention, the outer wall of the traction member is provided with a plurality of spring locking tongues evenly distributed along the circumference, and the inner wall of the male connector is provided with a second groove along the circumference.

[0020] According to the dynamic cable quick connection device provided by the present invention, the male connector is provided with a limiting member, and one end of the traction member is provided with a limiting part that cooperates with the limiting member;

[0021] When the spring latch engages with the second groove, the limiting portion abuts against the limiting member.

[0022] According to the dynamic cable quick connection device provided by the present invention, the end of the male connector is provided with a guide surface, the locking groove is located inside the guide surface, and the inner wall of the female connector is provided with a mating part that mates with the guide surface.

[0023] The dynamic cable quick connection device provided by the present invention further includes a bending reinforcement member, and the male connector is connected to the bending reinforcement member.

[0024] Another aspect of the present invention provides a dynamic cable guide, comprising a cable guide body and a dynamic cable guide quick connection device as described in any of the preceding claims, wherein the cable guide body is connected to a bending reinforcement member.

[0025] The working process of the dynamic cable quick connection device provided by this invention is as follows.

[0026] Before connection, the drive end of the telescopic drive component applies a driving force to one end of the rotating arm, causing the trigger plate located at the other end of the rotating arm to rotate, and causing the locking component on the main body of the trigger plate to engage with the locking sleeve bracket located on the outer wall of the connecting head.

[0027] During connection, the male connector is fixed to the traction component, and the male connector is continuously pulled into the female connector by the water surface traction device, and the male connector moves along the axial direction of the female connector. When the end of the male connector abuts against the trigger pin, it can drive the trigger pin to move outward along its axial direction and abut against the first abutting part. The first abutting part rotates away from the female connector and drives the locking component to rotate, so that the locking component and the locking sleeve bracket are released from the locking engagement. Since the tension spring has a radially inward pulling force on the locking pin, when the locking component and the locking sleeve bracket are released from the locking engagement, the tension spring can pull the locking pin to move radially inward and enter the locking groove on the outer wall of the male connector. At this point, the connection between the male connector and the female connector is completed.

[0028] When disengaging, the driving end of the telescopic drive applies a driving force to one end of the rotating arm, causing the tension spring to pull the locking pin out of the locking groove, and causing the locking fastener on the main body of the trigger plate to engage with the locking sleeve bracket on the outer wall of the connecting female. The traction device is then used to lower the traction component underwater and connect it to the connecting male, pulling the connecting male along the axial direction of the connecting female, thus disengaging the connecting male from the connecting female.

[0029] The dynamic cable guide quick connection device provided by this invention enables rapid connection between the male and female connectors and allows the male connector to quickly detach from the female connector. This solves the problem of existing technologies that use permanent connections between the cable and the machine, requiring divers to dive underwater, which is cumbersome and risky. Furthermore, the dynamic cable guide quick connection device provided by this invention only requires simple extension and retraction control of the telescopic drive component; all other transmissions are mechanical, eliminating the need for various sensors and making it suitable for underwater use.

[0030] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0052] The following is combined with Figures 1 to 13 This invention describes the dynamic cable guide quick connection device and the dynamic cable guide provided by the present invention.

[0053] See Figures 1 to 3 As shown, the dynamic cable guide quick connection device provided in this embodiment of the invention includes: a male connector 10, a female connector 20, a traction member 30, and a bending reinforcement member 40.

[0054] The outer wall of the male connector 10 is provided with a locking groove 110 along the circumference. Both ends of the female connector 20 are provided with openings. The outer wall of the female connector 20 is provided with a plurality of locking units 50 at intervals along the circumference. The locking unit 50 includes a locking component 510 and a triggering component 520.

[0055] The locking assembly 510 includes a telescopic drive member 511, a rotating arm 512, a locking pin 513, and a tension spring 514. The telescopic drive member 511 is disposed on the outer wall of the connecting female head 20. The first end of the rotating arm 512 abuts against the output end of the telescopic drive member 511, and the middle part of the rotating arm 512 is rotatably connected to the outer wall of the connecting female head 20 so that the rotating arm 512 can swing in a first direction. The locking pin 513 is radially inserted into the first sliding groove of the connecting female head 20 and slides in cooperation with the first sliding groove. One end of the tension spring 514 is connected to the connecting female head 20, and the other end of the tension spring 514 is connected to the locking pin 513. The locking pin 513 is connected to the rotating arm 512, and the connection point between the locking pin 513 and the rotating arm 512 is located on the side close to the telescopic drive member 511.

[0056] The trigger assembly 520 includes a trigger plate 521, a locking member 522, a locking sleeve bracket 523, and a trigger pin 524. The trigger plate 521 includes a main body 5211 and a first abutting part 5212. The first abutting part 5212 is located at the first end of the main body 5211. The trigger plate 521 is rotatably connected to the second end of the rotating arm 512. The locking member 522 is connected to the main body 5211. The locking sleeve bracket 523 is located on the outer wall of the connecting female head 20. The trigger pin 524 passes through the second sliding groove of the connecting female head 20 and slides in cooperation with the second sliding groove.

[0057] When the trigger component 520 is not triggered, the locking component 522 engages with the locking sleeve bracket 523, and the tension spring 514 exerts a radially inward pulling force on the locking pin 513, so that the end face of the locking pin 513 is located in the first sliding groove.

[0058] When the trigger assembly 520 is triggered, one end of the male connector 10 abuts against the trigger pin 524, causing the locking fastener 522 to disengage from the locking sleeve bracket 523, and causing the tension spring 514 to pull the locking pin 513 radially inward, so that the end face of the locking pin 513 is located in the locking groove 110.

[0059] The traction member 30 is detachably connected to the male connector 10, and the traction member 30 is used to pull the male connector 10 to move axially along the female connector 20.

[0060] It should be noted that the above-mentioned "enabling the rotating arm 512 to swing in the first direction" specifically means that the rotating arm 512 can swing in a set direction with its rotation connection point with the connecting female head 20 as the center.

[0061] The dynamic cable quick-connection device provided by this invention enables rapid connection between the male connector 10 and the female connector 20, and allows the male connector 10 to quickly detach from the female connector 20. This solves the problem of the existing technology where a permanent connection between the cable and the machine is required, necessitating underwater operations by divers, which is cumbersome and risky. Furthermore, the dynamic cable quick-connection device provided by this invention only requires simple extension and retraction control of the telescopic drive component 511; the rest uses mechanical transmission, eliminating the need for various sensors and making it suitable for underwater use.

[0062] Specifically, the working process of the dynamic cable quick connection device provided by the present invention is as follows.

[0063] Before connection, the driving end of the telescopic drive member 511 applies a driving force to one end of the rotating arm 512, causing the trigger plate 521 located at the other end of the rotating arm 512 to rotate, and causing the locking member 522 on the main body 5211 of the trigger plate 521 to lock and engage with the locking sleeve bracket 523 located on the outer wall of the connecting female head 20.

[0064] During connection, the male connector 10 is fixed to the traction member 30, and the male connector 10 is continuously pulled into the female connector 20 by the water surface traction device, and the male connector 10 moves along the axial direction of the female connector 20. When the end of the male connector 10 abuts against the trigger pin 524, it can drive the trigger pin 524 to move outward along its axial direction and abut against the first abutting part 5212. The first abutting part 5212 rotates away from the female connector 20 and drives the locking member 522 to rotate, so that the locking member 522 and the locking sleeve bracket 523 are released from the locking engagement. Since the tension spring 514 has a radially inward pulling force on the locking pin 513, when the locking member 522 and the locking sleeve bracket 523 are released from the locking engagement, the tension spring 514 can pull the locking pin 513 to move radially inward and enter the locking groove 110 on the outer wall of the male connector 10. At this point, the male connector 10 and the female connector 20 are connected.

[0065] When disconnecting, the driving end of the telescopic drive member 511 applies a driving force to one end of the rotating arm 512, causing the tension spring 514 to pull the locking pin 513 out of the locking groove 110, and causing the locking member 522 on the main body 5211 of the trigger plate 521 to engage with the locking sleeve bracket 523 on the outer wall of the connecting female head 20. The traction member 30 is then lowered underwater by a surface traction device and connected to the connecting male head 10, and the connecting male head 10 is pulled to move axially along the connecting female head 20, causing the connecting male head 10 to disengage from the connecting female head 20.

[0066] See Figure 1As shown in the example, in this embodiment, the outer wall of the female connector 20 is provided with four locking units 50, which are evenly distributed circumferentially on the outer wall of the female connector 20. The four locking units 50 can be used to simultaneously connect the male connector 10 and the female connector 20, or to disconnect the male connector 10 from the female connector 20.

[0067] It should be noted that in some embodiments, the number of locking units 50 can be configured according to the different specifications of the male connector 10 and the female connector 20. For example, when the radial parameters of the male connector 10 and the female connector 20 are small, only three locking units 50 can be set; when the radial parameters of the male connector 10 and the female connector 20 are large, more than three locking units 50 can be set, such as five or six.

[0068] See Figure 4 and Figure 5 As shown, the telescopic drive component 511 is a hydraulic actuator, comprising a hydraulic cylinder and a push rod. The hydraulic cylinder is mounted at a set angle to the outer wall of the connecting female head 20 via a mounting bracket 515, so that the push rod can apply a pushing force to the first end of the rotating arm 512, thereby allowing the rotating arm 512 to swing around its rotational connection point with the connecting female head 20. To increase the contact area between the end of the push rod and the first end of the rotating arm 512, a push plate is provided at the end of the push rod.

[0069] See Figure 4 and Figure 5 As shown, a connecting seat 516 is provided at a corresponding position on the outer wall of the connecting female head 20, and the middle part of the rotating arm 512 is rotatably connected to the connecting seat 516.

[0070] See Figure 4 and Figure 5 As shown, the locking assembly 510 also includes a connecting block 517. One end of the tension spring 514 is connected to the connecting female head 20, and the other end of the tension spring 514 is connected to the connecting block 517. The locking pin 513 is connected to the connecting block 517, and the connecting block 517 is connected to the rotating arm 512. When the driving end of the telescopic drive member 511 drives the first end of the rotating arm 512 to rotate away from the connecting female head 20, the rotating arm 512 can pull the locking pin 513 outward through the connecting block 517 and stretch the tension spring 514, so that it has a radially inward pulling force on the connecting block 517. When the driving end of the telescopic drive member 511 retracts, the tension spring 514 can drive the locking pin 513 to move radially inward through the connecting block 517.

[0071] In each locking assembly 510, the number of tension springs 514 is at least one. See also Figures 4 to 6As shown, in this embodiment, each locking component 510 has two tension springs 514, which are symmetrically arranged on both sides of the connecting block 517 to balance the tension applied to the locking pin 513, making the locking pin 513 slide more smoothly along the first groove.

[0072] See Figure 4 and Figure 5 As shown, the locking element 522 is a wedge-shaped locking element 522, and correspondingly, the locking sleeve bracket 523 is provided with a locking groove that matches the wedge-shaped locking element 522. When the locking element 522 moves to the position of the wedge-shaped locking element 522 under the action of the trigger plate 521, the locking element 522 and the locking sleeve bracket 523 can be configured for a locking engagement. When the first abutting part 5212 of the trigger plate 521 is abutted radially outward by the trigger pin 524, it can drive the trigger plate 521 to rotate and release the locking element 522 from the locking sleeve bracket 523.

[0073] See Figure 1 As shown, the bending reinforcement 40 is connected to one end of the connecting male 10 via a flange.

[0074] See Figure 5 As shown, according to some embodiments of the present invention, the trigger assembly 520 further includes a spring pressing mechanism, which includes a sleeve 525, a compression spring 526, and a pressing member 527. A third sliding groove is formed in the sleeve 525, and the pressing member 527 is slidably fitted in the third sliding groove. One end of the compression spring 526 is connected to the bottom of the third sliding groove, and the other end of the compression spring 526 is connected to the pressing member 527. The trigger plate 521 further includes a second abutment portion 5213, which is located at the second end of the main body portion 5211. By providing the spring pressing mechanism, the pressing member 527 can be subjected to a spring force under the action of the compression spring 526, and the pressing member 527 can exert a pushing force on the second abutment portion 5213, so that the trigger plate 521 can be held at a set angle, thereby enabling the locking member 522 to lock and engage with the locking sleeve bracket 523 in a set posture.

[0075] Specifically, in this embodiment, the pressing member 527 includes a head and a rod. The compression spring 526 is sleeved on the rod of the pressing member 527 and abuts against the inner end face of the head. One end of the sleeve 525 is provided with an abutment platform, the inner end face of which abuts against one end of the spring, and the center of the abutment platform is provided with a clearance opening that allows the rod of the pressing member 527 to move freely.

[0076] See Figure 5 and Figure 6As shown, according to some embodiments of the present invention, the trigger assembly 520 further includes a locking rod 528 and a spring plunger 529. The spring plunger 529 is connected to the main body 5211, one end of the locking rod 528 is connected to the spring plunger 529, and the other end of the locking rod 528 is connected to the locking member 522. By setting the locking rod 528 and the spring plunger 529, when the output end of the telescopic drive member 511 drives the rotating arm 512 to rotate, the locking member 522 will first abut against the locking sleeve bracket 523. Under the action of the spring plunger 529, the locking member 522 will retract appropriately, and after the rotating arm 512 further rotates to a set angle, the locking member 522 will spring back and fall into the locking sleeve bracket 523 to complete the locking engagement, significantly improving the connection accuracy during locking. In addition, when the locking member 522 and the locking sleeve bracket 523 are in the locked engagement state, under the action of the spring plunger 529, the locking member 522 can be stably maintained in the current locking position.

[0077] See Figure 5 As shown, according to some embodiments of the present invention, the trigger assembly 520 further includes a return spring 530, which is sleeved on the trigger pin 524. One end of the return spring 530 is connected to the inner wall of the connecting female head 20, and the other end of the return spring 530 is connected to the trigger pin 524. By providing the return spring 530, when the end of the connecting male head 10 removes its abutment action on the trigger pin 524, the trigger pin 524 can return to its initial position under the action of the return spring 530, facilitating triggering when the connecting male head 10 subsequently enters the connecting female head 20. In addition, the spring can also keep the spring pin in a stable state, preventing it from contacting the first abutment part 5212 when not needed, thus causing the locking member 522 to disengage from the locking sleeve bracket 523.

[0078] See Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the male connector 10 is sleeved on the traction member 30, and the traction member 30 can move along the axial direction of the male connector 10; the male connector 10 is provided with a plurality of pre-fixing mechanisms 120 at intervals along the circumference, the pre-fixing mechanism 120 includes a push shaft 121 and a detachment member 122, the detachment member 122 is connected to the inner end of the push shaft 121, the push shaft 121 passes radially through the fourth sliding groove of the male connector 10 and slides in cooperation with the fourth sliding groove, the inlet end of the female connector 20 is provided with a flared pressure slope 210, and the outer wall of the traction member 30 is provided with a first groove 310 along the circumference.

[0079] In the initial state, the detachable part 122 is connected to the push shaft 121 and is located in the first position in the first groove 310. In the detached state, the detachable part 122 is detached from the push shaft 121 and is located in the second position in the first groove 310.

[0080] It should be noted that the "first position within the first groove 310" specifically refers to the position where the bottom surface of the detached part 122 is far from the bottom surface of the first groove 310, and the "second position within the first groove 310" specifically refers to the position where the bottom surface of the detached part 122 is close to the bottom surface of the first groove 310 (or where it connects with the bottom surface of the first groove 310).

[0081] By circumferentially spaced pre-fixing mechanisms 120 on the male connector 10, the traction member 30 can be fixed to the male connector 10 before it is connected to the female connector 20. Under the traction of the surface traction device, the male connector 10 is guided into the female connector 20, and the male connector 10 and the female connector 20 are connected to each other. After the male connector 10 and the female connector 20 are connected, the detached member 122 remains in the first groove 310, allowing the traction member 30 to be easily removed from the male connector 10. After the surface traction device pulls the traction member 30 ashore, the detached member 122 remaining in the first groove 310 can be removed.

[0082] Specifically, the detachment part 122 is a spring pin. When the male connector 10 enters the female connector 20 axially, the push shaft 121 is subjected to the pressure of the flared pressure slope 210 and moves radially inward, which in turn drives the detachment part 122 to move. When the connection position of the detachment part 122 and the push shaft 121 is flush with the mating surface of the male connector 10 and the female connector 20, the detachment part 122 can detach from the inner end of the connecting shaft and remain in the first groove 310.

[0083] According to some embodiments of the present invention, the length of the detachment member 122 is the same as the depth of the first groove 310. By configuring the length of the detachment member 122 to be the same as the depth of the first groove 310, it is possible to prevent the push shaft 121 from entering the first groove 310 and thus prevent the traction member 30 from being removed from the connecting male head 10 when the detachment member 122 is fully inserted into the first groove 310.

[0084] See Figure 2 and Figure 3As shown, according to some embodiments of the present invention, the outer wall of the traction member 30 is provided with a plurality of spring locking tongues 320 evenly distributed circumferentially, and the inner wall of the connecting male head 10 is provided with a second groove 130 circumferentially. By providing a plurality of spring locking tongues 320 evenly distributed circumferentially on the outer wall of the traction member 30 and providing a second groove 130 circumferentially on the inner wall of the connecting male head 10, when it is necessary to remove the connecting male head 10 from the connecting female head 20, the traction member 30 can be guided into the connecting male head 10 by the water surface traction device and moved along the axial direction of the connecting male head 10. When the spring locking tongues 320 are engaged in the second groove 130, the connecting male head 10 can be connected to the traction member 30, which facilitates the subsequent removal of the connecting male head 10 from the connecting female head 20 by the traction member 30.

[0085] Further, see Figure 3 As shown, according to some embodiments of the present invention, a limiting member 140 is provided inside the male connector 10, and a limiting portion cooperating with the limiting member 140 is provided at one end of the traction member 30; when the spring locking tongue 320 is engaged with the first groove 310, the limiting portion abuts against the limiting member 140. By providing a limiting member 140 inside the male connector 10, it can be made to cooperate with the limiting portion cooperating with the limiting member 140, thereby reducing the shearing force on the spring locking tongue 320 and ensuring the stability of the traction member 30 when removing the male connector 10 from the female connector 20.

[0086] See Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the end of the male connector 10 is provided with a guide surface 150, the locking groove 110 is located inside the guide surface 150, and the inner wall of the female connector 20 is provided with a mating portion 220 that cooperates with the guide surface 150. By providing a guide surface 150 at the end of the male connector 10, when the male connector 10 is inserted into the flared end of the female connector 20 using the traction member 30, the flared end can play a guiding role, making it easier for the male connector 10 to enter into the female connector 20, and reducing the operating accuracy requirements of the traction member 30. In addition, by providing a mating portion 220 that cooperates with the guide surface 150 on the inner wall of the female connector 20, the stability of the male connector 10 and the female connector 20 during connection can be improved, and the portion corresponding to the mating portion 220 can be adapted to trigger the installation of the ejector pin 524.

[0087] The working process of the dynamic cable guide quick connection device provided by the present invention will be described below. Please refer to [link / reference]. Figures 9 to 12 .

[0088] See Figure 9As shown, before connection, the driving end of the telescopic drive member 511 applies a driving force to one end of the rotating arm 512, causing the trigger plate 521 located at the other end of the rotating arm 512 to rotate, and causing the locking member 522 on the main body 5211 of the trigger plate 521 to lock and engage with the locking sleeve bracket 523 located on the outer wall of the connecting female head 20.

[0089] During this process, the drive end of the telescopic drive member 511 first abuts against one end of the rotating arm 512. The rotating arm 512 rotates around its rotation connection point with the connecting seat 516, causing the other end of the rotating arm 512 to move toward the outer wall of the connecting female head 20. The pressing member 527 applies a pushing force to the second abutting part 5213, so that the trigger plate 521 can be maintained at a set angle, and the locking member 522 connected to the trigger plate 521 abuts against the locking sleeve bracket 523. Under the action of the spring plunger 529, the locking member 522 retracts appropriately, and after the rotating arm 512 rotates further to the set angle, the locking member 522 springs back and falls into the locking sleeve bracket 523 to complete the locking engagement.

[0090] At the same time, the rotating arm 512 can pull the locking pin 513 outward through the connecting block 517 so that its end face is located in the first slide groove, and stretch the tension spring 514 so that the tension spring 514 has a radially inward pulling force on the connecting block 517. When the driving end of the telescopic drive member 511 retracts, the tension spring 514 can drive the locking pin 513 to move radially inward through the connecting block 517.

[0091] During connection, the male connector 10 is fixed to the traction member 30, and the male connector 10 is continuously pulled into the female connector 20 by the water surface traction device, causing the male connector 10 to move axially along the female connector 20. See also... Figure 10 As shown, when the end of the male connector 10 abuts against the inner end of the trigger pin 524, it can drive the trigger pin 524 to move outward along its axis and abut against the first abutment part 5212. The first abutment part 5212 rotates away from the female connector 20 and drives the locking member 522 to rotate, causing the locking member 522 to disengage from the locking sleeve bracket 523. Since the tension spring 514 has a radially inward pulling force on the locking pin 513, when the locking member 522 disengages from the locking sleeve bracket 523, the tension spring 514 can pull the locking pin 513 to move radially inward and enter the locking groove 110 on the outer wall of the male connector 10. At this point, the male connector 10 and the female connector 20 are connected.

[0092] During this process, the tension spring 514 pulls the locking pin 513 radially inward through the connecting block 517 and enters the locking groove 110 on the outer wall of the connecting male head 10.

[0093] After the male connector 10 and the female connector 20 are connected, the water surface traction device continues to drive the traction component 30 to move. The push shaft 121 is pressed down by the pressure slope 210, causing the detachment component 122 to move along the depth direction of the second groove 130. When the connection position of the detachment component 122 and the push shaft 121 is flush with the mating surface of the male connector 10 and the female connector 20, the detachment component 122 is detached from the inner end of the connecting shaft and remains in the first groove 310, so that the traction component 30 can be smoothly moved out of the male connector 10.

[0094] See Figure 11 and Figure 12 As shown, when disconnecting, the towing member 30 is guided into the male connector 10 by a surface traction device. When the spring locking tongue 320 on the outer wall of the male connector 10 engages with the first groove 310 and the limiting part abuts against the limiting member 140, the connection between the towing member 30 and the male connector 10 is complete. The driving end of the telescopic drive member 511 drives the rotating arm 512 to rotate, and pulls the locking pin 513 out of the locking groove 110 through the tension spring 514. Then, the towing member 30, together with the male connector 10, is pulled out from the female connector 20 by the surface traction device. After being pulled out, the towing member 30 and the male connector 10 can be sunk to the seabed for subsequent salvage, disassembly, and reuse.
