[0050] Combine the following Figures 1 to 13 The invention describes a dynamic cable guide quick connection device and a dynamic cable guide.

[0051] See also Figures 1 to 3 As shown, the dynamic cable guide quick connection device provided in the embodiment of the present invention includes: a connecting male head 10, a connecting female head 20, a traction member 30 and a bending reinforcement member 40.

[0052] The outer wall of the connecting male connector 10 is provided with a locking groove 110 along the circumferential direction, and both ends of the connecting female connector 20 are provided with openings. The outer wall of the connecting female connector 20 is provided with a plurality of locking units 50 at intervals along the circumferential direction, and the locking units 50 include a locking assembly 510 and a trigger assembly 520.

[0053] The locking assembly 510 includes a telescopic driving member 511, a rotating arm 512, a locking pin 513 and a tension spring 514. The telescopic driving member 511 is arranged 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 driving member 511. 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 along the first direction. The locking pin 513 is radially penetrated through the first sliding groove of the connecting female head 20 and slidably cooperates 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 driving member 511.

[0054] The trigger assembly 520 includes a trigger plate 521, a locking piece 522, a locking sleeve bracket 523 and a trigger ejector pin 524. The trigger plate 521 includes a main body 5211 and a first abutting portion 5212. The first abutting portion 5212 is arranged at a 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 piece 522 is connected to the main body 5211. The locking sleeve bracket 523 is arranged on the outer wall of the connecting female head 20. The trigger ejector pin 524 is penetrated through the second sliding groove of the connecting female head 20 and slidably cooperates with the second sliding groove.

[0055] When the trigger assembly 520 is not triggered, the locking member 522 is locked 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 surface of the locking pin 513 is located in the first sliding groove.

[0056] When the trigger assembly 520 is triggered, one end of the connecting male connector 10 abuts against the trigger ejector pin 524 , so that the locking member 522 and the locking sleeve bracket 523 are unlocked, and the tension spring 514 pulls the locking pin 513 to move radially inward, so that the end surface of the locking pin 513 is located in the locking groove 110 .

[0057] The pulling member 30 is detachably connected to the male connector 10 , and is used to pull the male connector 10 to move along the axial direction of the female connector 20 .

[0058] It should be noted that the above “enabling the rotating arm 512 to swing along the first direction” specifically means that the rotating arm 512 can swing along the set direction with the rotating connection point between the rotating arm 512 and the connecting female connector 20 as the center.

[0059] The dynamic cable guide quick connection device provided by the present invention can realize the quick connection of the connecting male head 10 and the connecting female head 20, and can make the connecting male head 10 quickly disengage from the connecting female head 20, which solves the defects of the prior art that the cable-machine is permanently connected, the divers need to dive underwater for operation, and the process is cumbersome and risky. In addition, the dynamic cable guide quick connection device provided by the present invention only needs to perform simple telescopic control on the telescopic drive member 511, and the rest are all driven by mechanical structure, and there is no need to set various sensor components, which is suitable for underwater use.

[0060] Specifically, the working process of the dynamic cable guide quick connection device provided by the present invention is as follows.

[0061] Before connection, the driving end of the telescopic driving member 511 applies a driving force to one end of the rotating arm 512, so that the trigger plate 521 located at the other end of the rotating arm 512 rotates, and the locking member 522 located on the main body 5211 of the trigger plate 521 is locked with the locking sleeve bracket 523 located on the outer wall of the connecting female head 20.

[0062] When connecting, the male connector 10 is fixed to the traction member 30, and the male connector 10 is continuously pulled into the female connector 20 through the water surface traction device, and the male connector 10 is moved axially along the female connector 20. When the end of the male connector 10 abuts against the trigger ejector pin 524, the trigger ejector pin 524 can be driven to move outward along its axial direction and abut against the first abutting portion 5212. The first abutting portion 5212 rotates in a direction 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 fit. 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 fit, 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.

[0063] When releasing the connection, the driving end of the telescopic driving member 511 exerts a driving action on one end of the rotating arm 512, so that the tension spring 514 pulls the locking pin 513 out of the locking groove 110, and the locking member 522 on the main body 5211 of the trigger plate 521 is locked with the locking sleeve bracket 523 on the outer wall of the female connector 20. The traction member 30 is put into the water through the surface traction device to connect with the male connector 10, and the male connector 10 is pulled to move along the axial direction of the female connector 20, so that the male connector 10 is disengaged from the female connector 20.

[0064] See also Figure 1As shown, as an example, in this embodiment, the outer wall of the female connector 20 is provided with four locking units 50, and the four locking units 50 are evenly distributed along the circumferential direction on the outer wall of the female connector 20. The male connector 10 and the female connector 20 are connected to each other or disconnected from the male connector 10 and the female connector 20 through the synchronous action of the four locking units 50.

[0065] It should be noted that, in some embodiments, different numbers of locking units 50 may be configured according to 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 may be provided; when the radial parameters of the male connector 10 and the female connector 20 are large, more than three locking units 50 may be provided, such as five, six, etc.

[0066] See also Figure 4 and Figure 5 As shown, the telescopic driving member 511 is a hydraulic driving member, which includes a hydraulic cylinder and a push rod. The hydraulic cylinder is mounted on the outer wall of the connecting female head 20 at a set angle through a mounting bracket 515, so that the push rod can exert a pushing action on the first end of the rotating arm 512, thereby enabling the rotating arm 512 to swing around its rotating connection point with the connecting female head 20. In order 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.

[0067] See also Figure 4 and Figure 5 As shown, a connection seat 516 is provided at a corresponding position of the outer wall of the connecting female connector 20 , and the middle portion of the rotating arm 512 is rotatably connected to the connection seat 516 .

[0068] See also Figure 4 and Figure 5 As shown, the locking assembly 510 further includes a connecting block 517, one end of a tension spring 514 is connected to the connecting female head 20, 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 driving member 511 drives the first end of the rotating arm 512 to rotate in a direction 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 exerts a radially inward pulling force on the connecting block 517. When the driving end of the telescopic driving member 511 is retracted, the tension spring 514 can drive the locking pin 513 to move radially inward through the connecting block 517.

[0069] In each locking assembly 510, the number of the tension spring 514 is at least one. Figures 4 to 6As shown, preferably, in this embodiment, in each locking assembly 510, there are two tension springs 514, and the two tension springs 514 are symmetrically arranged on both sides of the connecting block 517 to balance the tension applied to the locking pin 513, so that the locking pin 513 can slide more smoothly along the first sliding groove.

[0070] See also Figure 4 and Figure 5 As shown, the lock member 522 is a wedge-shaped lock member 522, and accordingly, the lock sleeve bracket 523 is provided with a lock groove matching the wedge-shaped lock member 522. When the lock member 522 is driven by the trigger plate 521 to move to the position where the wedge-shaped lock member 522 is located, the lock member 522 and the lock sleeve bracket 523 can be configured to be locked. When the first abutting portion 5212 of the trigger plate 521 is abutted radially outward by the trigger ejector pin 524, it can drive the trigger plate 521 to rotate, and release the lock member 522 and the lock sleeve bracket 523 from locking.

[0071] See also Figure 1 As shown, the bending reinforcement member 40 is connected to one end of the connecting male connector 10 via a flange.

[0072] See also 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 arranged 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 abutting portion 5213, which is arranged at the second end of the main body 5211. By providing the spring pressing mechanism, an elastic force can be applied to the pressing member 527 under the action of the compression spring 526, and the pressing member 527 can apply a thrust to the second abutting portion 5213, so that the trigger plate 521 can be maintained at a set angle, so that the locking member 522 can be locked with the lock sleeve bracket 523 in a set posture.

[0073] Specifically, in this embodiment, the pressing member 527 includes a head and a rod, and the compression spring 526 is sleeved on the rod of the pressing member 527 and abuts against the inner end surface of the head. An abutment platform is provided at one end of the sleeve 525, and the inner end surface of the abutment platform abuts against one end of the spring, and a clearance opening is provided at the center of the abutment platform for the rod of the pressing member 527 to move freely.

[0074] See also 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 providing the locking rod 528 and the spring plunger 529, when the output end of the telescopic driving member 511 drives the rotating arm 512 to rotate, the locking member 522 will first abut against the locking sleeve bracket 523, and under the action of the spring plunger 529, the locking member 522 will retract appropriately, and after the rotating arm 512 is further rotated to a set angle, the locking member 522 rebounds and falls into the locking sleeve bracket 523 to complete the locking match, which significantly improves the connection accuracy during locking. In addition, when the locking member 522 and the locking sleeve bracket 523 are in a locked state, under the action of the spring plunger 529, the locking member 522 can be stably maintained at the current locking position.

[0075] See also Figure 5 As shown, according to some embodiments of the present invention, the trigger assembly 520 further includes a reset spring 530, which is sleeved on the trigger ejector pin 524, one end of which is connected to the inner wall of the female connector 20, and the other end of which is connected to the trigger ejector pin 524. By providing the reset spring 530, when the end of the male connector 10 cancels the abutment against the trigger ejector pin 524, the trigger ejector pin 524 can return to the initial position under the action of the reset spring 530, so as to facilitate the subsequent triggering when the male connector 10 enters the female connector 20. In addition, the rune spring can also keep the spring ejector pin in a stable state, preventing it from contacting the first abutting portion 5212 when there is no need, causing the lock member 522 to release the lock fit with the lock sleeve bracket 523.

[0076] See also Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the connecting male head 10 is sleeved on the traction member 30, and the traction member 30 can move along the axial direction of the connecting male head 10; the connecting male head 10 is provided with a plurality of pre-fixing mechanisms 120 at intervals along the circumferential direction, and the pre-fixing mechanism 120 includes a pushing shaft 121 and a falling member 122, and the falling member 122 is connected to the inner end of the pushing shaft 121, and the pushing shaft 121 is radially penetrated through the fourth slide groove of the connecting male head 10 and slidably cooperates with the fourth slide groove, and the inlet end of the connecting female head 20 is provided with a flared pressure inclined surface 210, and the outer wall of the traction member 30 is provided with a first groove 310 along the circumferential direction.

[0077] In the initial state, the falling piece 122 is connected to the driving shaft 121 and is located at a first position in the first groove 310 . In the falling state, the falling piece 122 falls off from the driving shaft 121 and is located at a second position in the first groove 310 .

[0078] It should be noted that the above-mentioned “first position in the first groove 310” specifically refers to a position where the bottom surface of the fall-off piece 122 is farther from the bottom surface of the first groove 310, and the above-mentioned “second position in the first groove 310” specifically refers to a position where the bottom surface of the fall-off piece 122 is closer to the bottom surface of the first groove 310 (or connected to the bottom surface of the first groove 310).

[0079] By arranging a plurality of pre-fixing mechanisms 120 at intervals along the circumferential direction on the male connector 10, the traction member 30 can be fixed to the male connector 10 by the plurality of pre-fixing mechanisms 120 before the male connector 10 is connected to the female connector 20. Under the traction of the surface traction device, the male connector 10 is introduced 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 falling-off member 122 is retained in the first groove 310, and the traction member 30 can be smoothly taken out of the male connector 10. After the surface traction device pulls the traction member 30 ashore, the falling-off member 122 retained in the first groove 310 can be taken out.

[0080] Specifically, the fall-off piece 122 is a spring pin. When the male connector 10 enters the female connector 20 axially, the pushing shaft 121 moves radially inwardly due to the pressure of the flared pressure ramp 210, and drives the fall-off piece 122 to move. When the connection position between the fall-off piece 122 and the pushing shaft 121 is flush with the separation surface of the male connector 10 and the female connector 20, the fall-off piece 122 can fall off from the inner end of the connecting shaft and remain in the first groove 310.

[0081] According to some embodiments of the present invention, the length of the drop-out member 122 is the same as the depth of the first groove 310. By configuring the length of the drop-out member 122 to be the same as the depth of the first groove 310, when the drop-out member 122 completely enters the first groove 310, the push shaft 121 can be prevented from entering the first groove 310, thereby preventing the pulling member 30 from being removed from the male connector 10.

[0082] See also Figure 2 and Figure 3As shown, according to some embodiments of the present invention, the outer wall of the traction member 30 is evenly provided with a plurality of spring locking tongues 320 along the circumferential direction, and the inner wall of the connecting male head 10 is circumferentially provided with a second groove 130. By evenly providing a plurality of spring locking tongues 320 along the circumferential direction on the outer wall of the traction member 30, and providing a second groove 130 along the circumferential direction on the inner wall of the connecting male head 10, when it is necessary to take the connecting male head 10 out of the connecting female head 20, the traction member 30 can be introduced into the connecting male head 10 through the water surface traction device, and moved along the axial direction of the connecting male head 10, and when the spring locking tongue 320 is stuck in the second groove 130, the connecting male head 10 can be connected to the traction member 30, so that the connecting male head 10 can be taken out of the connecting female head 20 through the traction member 30 later.

[0083] Further, see Figure 3 As shown, according to some embodiments of the present invention, a limiting member 140 is provided in 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 the limiting member 140 in the male connector 10, it can be engaged with the limiting portion cooperating with the limiting member 140, thereby reducing the shear force on the spring locking tongue 320, and ensuring the stability when the traction member 30 takes the male connector 10 out of the female connector 20.

[0084] See also Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, a guide surface 150 is provided at the end of the male connector 10, the locking groove 110 is located on the inner side of the guide surface 150, and a matching portion 220 matching with the guide surface 150 is provided on the inner wall of the female connector 20. By providing the guide surface 150 at the end of the male connector 10, when the male connector 10 is inserted from the flared end of the female connector 20 by the traction member 30, the flared end can play a guiding role, so that the male connector 10 is easier to enter the female connector 20, and the operating accuracy requirement of the traction member 30 is reduced. In addition, by providing the matching portion 220 matching 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 when connected can be ensured, and the corresponding portion of the matching portion 220 can be suitable for triggering the installation of the ejector pin 524.

[0085] The following is an explanation of the working process of the dynamic cable guide quick connection device provided by the present invention. Figures 9 to 12 .

[0086] See also Fig. 9As shown, before connection, the driving end of the telescopic driving member 511 applies a driving force to one end of the rotating arm 512, so that the trigger plate 521 located at the other end of the rotating arm 512 rotates, and the locking member 522 located on the main body 5211 of the trigger plate 521 is locked with the locking sleeve bracket 523 located on the outer wall of the connecting female head 20.

[0087] During this process, the driving end of the telescopic driving member 511 first abuts against one end of the rotating arm 512, and the rotating arm 512 rotates around its rotating connection point with the connecting seat 516, so that the other end of the rotating arm 512 moves toward the direction close to the outer wall of the connecting female head 20, and the pressing member 527 applies a thrust to the second abutting portion 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 is further rotated to the set angle, the locking member 522 rebounds and falls into the locking sleeve bracket 523 to complete the locking match.

[0088] 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 sliding groove, and lengthen 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 driving member 511 is retracted, the tension spring 514 can drive the locking pin 513 to move radially inward through the connecting block 517.

[0089] When connecting, 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 surface traction device, and the male connector 10 is moved along the axial direction of the female connector 20. Fig.10 As shown, when the end of the male connector 10 abuts against the inner end of the trigger pin 524, the trigger pin 524 can be driven to move outward along its axial direction and abut against the first abutting portion 5212. The first abutting portion 5212 rotates in a direction away from the female connector 20 and drives the lock member 522 to rotate, so that the lock member 522 and the lock sleeve bracket 523 are released from the lock. Since the tension spring 514 has a radially inward pulling force on the lock pin 513, when the lock member 522 and the lock sleeve bracket 523 are released from the lock, the tension spring 514 can pull the lock pin 513 to move radially inward and enter the lock 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.

[0090] During this process, the tension spring 514 pulls the locking pin 513 through the connecting block 517 to move radially inward and enter the locking groove 110 on the outer wall of the connecting male connector 10 .

[0091] After the connection between the male connector 10 and the female connector 20 is completed, the water surface traction device continues to drive the traction member 30 to move, and the pushing shaft 121 is pressed downward by the pressure inclined surface 210 to cause the falling member 122 to move along the depth direction of the second groove 130, and when the connection position between the falling member 122 and the pushing shaft 121 is flush with the separation surface of the male connector 10 and the female connector 20, the falling member 122 falls off from the inner end of the connecting shaft and stays in the first groove 310, so that the traction member 30 can be smoothly moved out of the male connector 10.

[0092] See also Fig.11 and Fig.12 As shown, when releasing the connection, the traction member 30 is introduced into the male connector 10 through the water surface traction device. When the spring lock tongue 320 on the outer wall of the male connector 10 is engaged with the first groove 310 and the limiting portion abuts against the limiting member 140, the connection between the traction member 30 and the male connector 10 is completed. The driving end of the telescopic driving 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, and then the traction member 30 is dragged out of the female connector 20 together with the male connector 10 through the water surface traction device. After being dragged out, the traction member 30 together with the male connector 10 can be sunk to the seabed, and can be salvaged and disassembled later for reuse.
