[0002] With the deepening of marine resource development and scientific research activities, the application of cable-bearing carriers is becoming more and more widespread. The cable-bearing carrier is connected to the mother ship through a cable and carries various scientific instruments to perform underwater environmental monitoring, resource exploration and other tasks. At present, the deployment and recovery of the cable-bearing carrier mainly relies on manual operation or special capture devices, which has many limitations.

[0006] Further, the guide rail is divided into a rack segment and a sliding segment from the beginning to the end; the rack segment comprises racks symmetrically arranged on both sides of the guide rail, and the end of the rack is provided with an auxiliary gear.

[0007] Further, the motion mechanism comprises a connecting bracket, a gear drive motor and a motion gear located between the racks and engaged with the racks; the top end of the connecting bracket is connected to the bottom of the base body, and the bottom end of the connecting bracket is rotationally connected with the motion gear; the gear drive motor is installed inside the base body, and the output end thereof extends out of the bottom of the base body and is connected with the motion gear; the gear drive motor drives the motion gear to rotate so that the motion gear reciprocates along the extension direction of the racks; the motion gear is engageable with the auxiliary gear.

[0008] Further, two bosses are symmetrically arranged on both sides of the guide rail shell along the extension direction of the guide rail, and the upper surfaces of the bosses constitute a rolling track; two rolling wheels are symmetrically arranged on both sides of the connecting bracket, and the rolling wheels reciprocally roll along the rolling track.

[0009] Further, the width of the through slot is not greater than the distance between the inner end surfaces of the two rolling wheels, so that the platform can limit the rolling wheels in the radial direction.

[0012] Further, the base body is provided with a buffer pad on the side facing the end of the through slot, and the buffer pad is provided with a transition section extending towards the end of the through slot.

[0013] Compared with the prior art, the present application has the following advantages: 1. The present application can be directly mounted on various types of launching and recovery platforms of a mother ship or a navigation body, and more than one set of the device can be arranged on the launching and recovery platform. Through the cooperation of the motion base assembly, the cable guiding mechanism and the motion guide rail assembly, the real-time guidance and adjustment of the launching and recovery posture of the carrier can be realized, which not only solves the problem that the traditional device cannot adapt to complex launching and recovery platforms and cannot adjust the recovery trajectory in real time, but also realizes the automatic batch launching and recovery of multiple cable carriers, greatly improving the operation efficiency.

[0014] 2. The guide rail of the present application is divided into a rack section and a sliding section. The rack section can drive the motion gear to move along the rack through the gear drive motor, realizing the controllable straight-line movement of the carrier. The sliding section can complete the posture transition with the help of the self-weight of the carrier and the tension of the cable. The segmented guide rail design combined with the transition effect of the auxiliary gear ensures the power connection and trajectory accuracy of the carrier in different motion stages.

[0016] 4. The cable guiding mechanism adopts double wire passing guide wheels cooperating with the cable guiding base, which can limit and guide the cable in two directions, so that the cable remains tensioned and does not fall off during the whole process of carrier deployment and recovery, avoiding the influence of cable deviation and winding on the smooth progress of carrier attitude adjustment and deployment operation.

[0017] 5. The buffer pad not only reduces the impact when the carrier is contacted, but also assists the carrier in adjusting the attitude, which facilitates the precise clamping of the locking mechanism and improves the safety of the carrier locking process and the adaptability to different attitude carriers.

DETAILED DESCRIPTION

[0029] In order to make the purpose-technical solutions and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0030] Example 1 The present embodiment provides a cable guide locking and retracting device arranged on a retraction platform 6 of a mother ship or a navigation body. The retraction platform 6 is connected to a tail deck (or a ship cabin interior) and submerged in the water surface. The tail deck or the ship cabin interior is higher than the water surface, and the retraction platform 6 has a certain inclination angle towards the water surface. The retraction platform 6 is provided with a through groove for mounting the cable guide locking and retracting device. The position and orientation of the through groove are determined according to the deployment requirements of the carrier 4. In the extension direction of the through groove, the end of the through groove away from the water surface is the head end, and the end of the through groove close to the water surface is the tail end.

[0031] As shown in Figure 1 , the cable guide locking and retracting device includes a movement base assembly 1, a cable guide mechanism 2, and a movement guide rail assembly 5. The carrier 4 is moved back and forth along the extension direction of the through groove by the cooperation of the movement base assembly 1 and the movement guide rail assembly 5 to complete the deployment and recovery. The cable guide mechanism 2 is arranged on the movement base assembly 1 and used to limit and guide the cable 3 of the carrier 4 during the movement of the carrier 4. The specific connection relationship is as follows: As shown in Figure 3 , 4 , the movement guide rail assembly 5 includes a guide rail shell 55 with an open top end and a guide rail arranged on the inner side bottom of the guide rail shell 55. The movement guide rail shell 55 has a mounting interface mounted on the through groove of the retraction platform 6. The guide rail shell 55 is arranged on the bottom of the retraction platform 6 in position correspondence with the through groove, and the extension directions of the through groove and the guide rail are parallel to each other.

[0032] The guide rail is divided into a rack section and a sliding section from the beginning to the end. The rack section includes racks 52 symmetrically arranged on both sides of the guide rail, and the racks 52 are provided with auxiliary gears 53 at the ends for the transition between the rack section and the sliding section. The guide rail shell 55 is symmetrically provided with two bosses on both sides in the extension direction of the guide rail, and the upper surfaces of the bosses form a rolling track 54; the rolling track 54 is provided with a buffer anti-collision strip 51 at both ends, and the two ends of the rolling track 54 refer to the beginning and the end of the bosses in the extension direction of the guide rail.

[0033] The motion base assembly 1 includes a base body 11, a motion mechanism, and a locking mechanism 15. The locking mechanism 15 is arranged on the base body 11 and is used for limiting or releasing the carrier 4 on the base body 11. The base body 11 is provided with a buffer pad 13 at the side of the end of the through groove, and the buffer pad 13 is located below the locking mechanism 15. The bottom end of the buffer pad 13 is provided with a transition section extending toward the end of the through groove. The buffer pad 13 not only reduces the impact of contact, but also guides the posture adjustment of the carrier 4 to assist the carrier 4 to be locked by the locking mechanism 15.

[0034] In this embodiment, as shown in Figure 5 The locking mechanism 15 includes a locking support, an annular lock 12, a lock driving motor 14, and a locking connecting frame. The lock driving motor 14 is fixedly installed on the top of the base body 11 through the locking support. The annular lock 12 includes two symmetrically arranged locking members, the middle parts of the two locking members are hinged through a hinge shaft, and the hinge shaft is fixed on the locking support. One end of each locking member is in a semicircular arc structure, and the other end of each locking member is provided with a cylindrical slider. The locking connecting frame is provided with a circular arc groove, and the two cylindrical sliders are slidingly connected in the circular arc groove. The output end of the lock driving motor 14 drives the locking connecting frame to move toward or away from the hinge shaft, so that the cylindrical sliders move along the circular arc groove, and the two semicircular arc structures are opened or closed, so as to lock and release the limiting rod on the carrier 4, so that the carrier 4 and the base body 11 become an integral whole to move together or the carrier 4 is separated from the base body 11 to be placed alone. In other embodiments, the locking mechanism 15 can adopt other locking structures, and the specific mechanism of the locking mechanism 15 is not limited, as long as it can complete the limiting and releasing actions of the carrier 4.

[0035] In this embodiment, as shown in Figure 2 The cable guide mechanism 2 includes a cable guide base 22, a cable guide support 23, and two wire guide wheels 21. The cable guide base 22 is fixed on the top end of the base body 11 through the cable guide support 23, and two support plates are arranged on both sides of the cable guide base 22 and are parallel to each other. The wire guide wheels 21 are located between the two support plates and are rotatably connected to the two support plates at both ends; the rotation axes of the two wire guide wheels 21 are parallel to each other and perpendicular to the extension direction of the guide rail. The wire guide wheels 21 have a structure of thin in the middle and thick at both ends, the cable 3 passes through and is slidingly connected between the two wire guide wheels 21, and the cable 3 is limited in the middle of the wire guide wheels 21.

[0036] The base body 11 is located on the upper surface of the take-up and take-down platform 6. The motion mechanism is connected between the base body 11 and the guide rail. The motion mechanism can reciprocate along the extension direction of the guide rail, so that the base body 11 drives the carrier 4 to reciprocate along the extension direction of the through groove through the locking mechanism 15.

[0037] Specifically, such as Figure 4 As shown, the motion mechanism includes a connecting bracket 110, a gear drive motor 16, and a motion gear 19 located between and meshing with the rack 52. The top of the connecting bracket 110 is connected to the bottom of the base body 11, and the bottom of the connecting bracket 110 is rotatably connected to the motion gear 19. Two rolling wheels 18 are symmetrically arranged on both sides of the connecting bracket 110. The rotation axis of the rolling wheels 18 is perpendicular to the extension direction of the guide rail, and the rolling wheels 18 are located on the rolling track 54.

[0038] The gear drive motor 16 is installed inside the base body 11, and its output end extends out of the bottom of the base body 11 and is connected to the motion gear 19. The gear drive motor 16 drives the motion gear 19 to rotate so that it reciprocates along the extension direction of the rack 52. At the same time, the motion gear 19 drives the rolling wheel 18 to reciprocate along the rolling track 54 through the connecting bracket 110.

[0039] The rolling track 54 is provided with buffer anti-collision strips 51 at both ends. The sum of the thickness of the buffer anti-collision strip 51 (thickness refers to the length along the extension direction of the guide rail) and the radius of the rolling wheel 18 should not be less than the radius of the moving gear 19. Therefore, when the rolling wheel 18 moves to both ends of the rolling track 54, it stops moving after contacting the buffer anti-collision strip 51, and the moving gear 19 stops moving accordingly. At this time, the moving gear 19 will not collide with both ends of the guide rail housing 55.

[0040] As an improvement, the width of the through groove is not less than the outer diameter of the connecting bracket 110, and the width of the through groove is not greater than the distance between the inner end faces of the two rolling wheels 18, so that the take-up and put-down platform 6 can radially limit the rolling wheels 16. That is to say, the two rolling wheels 18 will not be exposed to the through groove provided in the take-up and put-down platform 6, and the rolling wheels 18 are located between the take-up and put-down platform 6 and the upper surface of the boss, and are radially limited by the two.

[0041] The moving gear 19 can be engaged with the auxiliary gear 53. When the moving gear 19 (the base body 11 is initially located at the first end of the through groove) is moved to the end of the rack 52 from the first end of the guide rail, the moving gear 19 is engaged with the auxiliary gear 53, so as to smoothly transition into the sliding section. Due to the self-inclination of the platform 6, the moving gear 19 continues to slide along the sliding section under the action of the cable 3 and the self-weight of the carrier 4, until the end of the sliding section. At this time, the locking mechanism 15 releases the carrier 4, and the deployment is completed. During the entire deployment process, the cable 3 is always limited and guided by the cable guide mechanism 2, and the carrier 4 is limited on the base body 11 and moves along the through groove, so as to realize real-time guidance of the deployment posture of the carrier 4.

[0042] Similarly, when the carrier 4 is recovered, the base body 11 is located at the end of the guide rail sliding section, the winch recovers the cable 3, the carrier 4 slides out of the water to the platform 6 under the action of the cable 3, the cable 3 is guided and limited by the cable guide mechanism 2, so that the posture of the carrier 4 is gradually adjusted, and finally contacts the buffer pad 13 on the base body 11. At this time, the limiting rod on the carrier 4 is in place (located in the ring lock 12), the ring lock driving motor 14 controls the ring lock 12 to close through the locking mechanism support 15, locks the limiting rod, and thus locks the carrier 4. The winch continues to recover the cable 3, and through the tension of the cable 3, the rolling wheel 18 rolls on the rolling track 54, so that the base body 11 with the locked carrier 4 moves from the end of the sliding section to the rack section.

[0043] When the rolling wheel 18 passes through the position corresponding to the auxiliary gear 53, the moving gear 19 is engaged with the rack 52, the gear driving motor 16 drives the moving gear 19 to rotate through the shaft coupling 17, and the rotation of the moving gear 19 is converted into linear motion along the extension direction of the rack 52 through the engagement of the moving gear 19 with the two racks 52. At the same time, the rolling wheel 18 rolls on the rolling track 54, until the moving gear 19 drives the base body 11 to move to the first end of the guide rail through the connecting frame 110. At this time, the moving base assembly 1 is located at the first end of the through groove, and the automatic recovery of the carrier 4 is completed.

[0044] Example 2 On the basis of example 1, the application of the cable guide and locking deployment and recovery device on a complex deployment and recovery platform is introduced below.

[0045] As Figure 6As shown, in this embodiment, the mother ship's launching and recovering platform 6 includes a launching and recovering panel 61 and a tilting device composed of a hydraulic cylinder, a hydraulic rod 63, a connecting rod 64, and a bottom support 62. The bottom support 62 is mounted on the mother ship. One end of the launching and recovering panel 61 near the winch is hinged to one end of the connecting rod 64, and the other end of the connecting rod 64 is hinged to the bottom support 62. The hydraulic cylinder is hinged to the bottom support 62, and its hydraulic rod 63 is hinged to the middle of the connecting rod 64. The bottom of the launching and recovering panel 61 has two long sliding grooves, and the bottom support 62 has an upwardly extending pin at one end near the stern of the deck. The pin is slidably connected within the long sliding grooves. Figure 6 In the state shown, the end of the long slipway closest to the mother ship is the bow, and the end of the long slipway closest to the water surface is the stern.

[0046] The hydraulic rod 63 extends and retracts, pushing the connecting rod 64 to rotate at its hinge point with the bottom bracket 62, thereby causing the retractable panel 61 to extend or retract. Figure 7 As shown, the hydraulic rod 63 retracts, the pin of the bottom bracket 62 is at the tail end of the long slide, and the retraction panel 61 retracts to above the deck. Figure 6 As shown, the hydraulic rod 63 extends, the pin of the bottom bracket 62 is at the beginning of the long slide, and the retractable panel 61 extends into the water.

[0047] like Figure 8 As shown, multiple through slots are set on the deployment panel 61 according to the specific deployment requirements of the carrier 4. The orientation and position of each through slot are designed according to actual needs, which can make reasonable use of the mother ship space. Multiple sets of guide cable locking deployment and recovery devices are installed corresponding to the through slots to realize the automatic deployment and recovery of multiple carriers 4.

[0048] During the deployment process, such as Figure 9 As shown, the hydraulic cylinder drives the deployment and retrieval panel 61 to extend, and the tail of the deployment and retrieval panel 61 is submerged in the water. After the deployment and retrieval panel 61 extends into place, the locking mechanism 15 keeps the carrier 4 locked; according to the deployment sequence, the single deployment and retrieval platform 6 can retrieve and deploy multiple cable carriers 4.

[0049] Multiple cable locking and unloading devices operate individually or simultaneously: When the cable 3 is released in conjunction with the mother ship's winch, the gear drive motor 16 drives the moving gear 19 to rotate, causing the connecting bracket 110 to move the carrier 4 along the extension direction of the through groove to a designated position (corresponding to the position of the auxiliary gear 53) via the base body 11. The gear drive motor 16 is then turned off. Under the weight of the cable 3 and the carrier 4, the moving gear 19 slides down to the end of the sliding section, meaning the base body 11 drives the carrier 4 down to the end of the through groove. Depending on the actual situation, the latter half of the sliding section of any cable locking and unloading device can be set as a zigzag segment with rounded corners to adjust the orientation and attitude of the carrier 4.

[0050] Locking mechanism 15 releases carrier 4, and carrier 4 slides into the water along the tail slide plate of retraction panel 61, as...Figure 10 After the deployment is completed, the hydraulic cylinder is controlled to restore the initial state of the panel 61, and the cable guiding mechanism 2 keeps the limiting effect on the cable 3.

[0051] During the recovery process, the tail of the panel 61 is first immersed in water, and the winch recovers the cable 3 to drive the carrier 4 to slide through the roller group at the tail of the panel 61 and onto the panel 61. The carrier 4 is in contact with the buffer pad 13 below the locking mechanism 15, and the cable 3 above is kept in tension. The annular lock 12 locks the limiting rod of the cable carrier 4, and the carrier 4 can be recovered and locked in sequence. The hydraulic cylinder is controlled to restore the initial state of the panel 61, and the annular lock 12 is kept in the locked state. The movement base assembly 1 cooperates with the movement guide assembly 5 to drive the cable guiding and locking deployment device to move the carrier 4 along the through groove to the designated position, and the recovery is completed.

[0052] As a modular solution, the present application can be mounted on different mother ship deployment platforms 6 to provide cable 3 guiding, deployment and recovery posture guiding, and locking and releasing functions for the carrier 4. The cable guiding and locking deployment device can adapt to various complex deployment platforms 6, solve the difficulty of real-time adjustment of the recovery trajectory of different carriers 4, and realize automatic deployment and recovery of multiple cable carriers 4.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
