[0002] As an important component of the underwater operation platform, the winch system is responsible for the power transmission, deployment and recovery of underwater operation equipment. At present, the winch system is mainly divided into deck / shore-based winch system and underwater winch system. Among them, the deck / shore-based winch system solution is relatively mature and can meet the mission requirements of the underwater operation platform. As the underwater operation mode changes to underwater deployment methods such as base station type and resident type, the underwater winch system is required to support the deployment, recovery and long-term storage functions of the operation platform underwater. It will play an increasingly critical role in the application of new deep-sea operation modes.

[0003] At present, the design of underwater winch systems has problems such as low integration, time-consuming and labor-intensive deployment, poor cable storage capacity, low intelligence, and poor operation reliability. When the design operating depth of the underwater winch system for deep-sea operations is 2,000 meters, the cable storage length can reach 7,000 meters. Therefore, it is particularly important to ensure that the cable can work continuously and reliably for a long time at a depth of 2,000 meters.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] like Figures 1 to 12 As shown, the present invention comprises a winch frame 1, and the winch frame 1 is provided with a cable storage and discharge mechanism 2, a cable guide mechanism 3, a towing cable mechanism 4 and a docking mechanism 5, wherein as shown in FIG. Figures 4-5 As shown, the cable storage and discharge mechanism 2 is provided with a cable storage drum 201 and a cable discharge assembly. Figure 6 As shown, the cable guiding mechanism 3 is provided with a cable steering guide wheel 302. Figures 7-8 As shown, the towing cable mechanism 4 is provided with a guide frame 401, a towing cable wheel 402 and a towing cable driving device 405, and the towing cable wheel 402 is driven to rotate by the towing cable driving device 405. Figure 2 As shown, the head end of the cable 6 is led out from the cable storage drum 201, passes through the cable arrangement assembly, then bypasses the cable steering guide wheel 302, the guide frame 401 and the towing wheel 402 in sequence, passes through the docking mechanism 5, and is connected to a connector 601. The connector 601 is used to connect with related equipment, such as Figures 10-11As shown, movable connector locking blocks 5031 are provided on both sides of the docking mechanism 5, and after the cable 6 is fully retracted (i.e. when the devices are docked), the connector 601 is inserted into the docking mechanism 5 and clamped and locked by the connector locking blocks 5031 on both sides.

[0037] like Figures 4-5 As shown, a drum driving device 203 (a hydraulic motor in this embodiment) is provided at one end of the cable storage drum 201, and the cable storage drum 201 is driven to rotate by the drum driving device 203. The cable arrangement assembly includes a slide 204, a lead screw 206 and a lead screw driving device 207, wherein the lead screw 206 is driven to rotate by the lead screw driving device 207 (a hydraulic motor in this embodiment). A nut sleeve 2041 is provided in the middle of the slide 204 and is sleeved on the lead screw 206. The rotation of the lead screw 206 drives the slide 204 to move through the nut sleeve 2041. Guide shafts 209 are provided on the upper and lower sides of the lead screw 206. Guide sleeves 2042 are provided on the upper and lower ends of the slide 204, and the guide sleeves 2042 are slidably sleeved on the guide shafts 209 on the corresponding side to play a moving guiding role. A cable arrangement guide roller group 202 is provided at the upper end of the slide 204, and the head end of the cable 6 passes through the cable arrangement guide roller group 202.

[0038] In this embodiment, the upper end of the slide 204 is provided with an angle detection sensor for real-time detection of the deflection angle of the cable 6 between the cable storage drum 201 and the cable arrangement guide roller group 202. When the deflection angle of the cable 6 is greater than the set threshold, the equipment system controls the screw drive device 207 to start, thereby driving the slide 204 to move in the direction of reducing the deflection angle of the cable 6 until the deflection angle of the cable 6 returns to the set range, and then the screw drive device 207 stops running. The present invention controls the discharge of the cable 6 through a cable arrangement assembly independent of the cable storage drum 201, thereby ensuring the orderly arrangement of the cable 6 on the cable storage drum 201, and is particularly suitable for storing the cable 6 in a deep-sea operating environment (when the operating water depth is 2000 meters, the cable storage length can reach 7000 meters). The angle detection sensor is a well-known technology in the art and is a commercially available product.

[0039] like Figure 4 and Fig.12As shown, in this embodiment, the winch frame 1 is provided with a support seat mounting plate 101, a first vertical plate 102 and a second vertical plate 103, wherein the two ends of the cable storage drum 201 are rotatably mounted on the drum support seat 205 on the corresponding side, the drum support seat 205 is mounted on the support seat mounting plate 101 on the corresponding side, the drum drive device 203 is mounted on the drum support seat 205 on either side, the lead screw 206 and the guide shaft 209 are both mounted on the first vertical plate 102 at one end and on the second vertical plate 103 at the other end, and a transmission assembly 208 is provided between the lead screw drive device 207 and the lead screw 206 for transmitting torque, and the transmission assembly 208 and the lead screw drive device 207 are both mounted on the first vertical plate 102. In this embodiment, the transmission assembly 208 can adopt a gear transmission or a sprocket chain transmission structure according to actual needs.

[0040] like Figure 6 As shown, the cable guiding mechanism 3 includes a bracket 301 and a code disc 303, wherein the bracket 301 is installed on the winch frame 1, and an axle pin force sensor 3012 is provided on the bracket 301, the cable steering guide wheel 302 and the code disc 303 are both installed on the axle pin force sensor 3012, the edge of the code disc 303 is provided with code disc teeth 3031, and the bracket 301 is provided with two proximity switches 3011 that cooperate with the code disc teeth 3031. When the present invention is working, the cable steering guide wheel 302 and the code disk 303 rotate synchronously. When the code disk teeth 3031 block the proximity switch 3011, the proximity switch 3011 is in an open state, and when it is not blocked, it is in a closed state. The present invention determines the installation spacing of the two proximity switches 3031 according to the pitch of the code disk teeth 3031, thereby ensuring that the two proximity switches 3031 cannot be opened or closed at the same time when the code disk 33 rotates, so as to determine whether the rotation of the cable steering guide wheel 302 is reversed. For example, if the first proximity switch 3011 is turned on first and the second proximity switch 3011 is turned on first, the rotation of the cable steering guide wheel 302 is reversed. In addition, the present invention can also obtain the rotation speed of the cable steering guide wheel 302 by detecting the continuous on / off signal sent by the proximity switch 3011, thereby monitoring the speed of the cable 6 retracting and releasing. The shaft pin force sensor 3012 is used to detect the tension of the cable 6 in real time. The proximity switch 3011 and the shaft pin force sensor 3012 are both well-known technologies in the art and are commercially available products. The present invention monitors the reversing and retracting speed of the cable 6 in real time through the structural design of the above-mentioned code disk 303 and proximity switch 3011, which is not affected by the complex environment of the 2000-meter deep sea and can ensure reliable detection and control of the retracting and releasing of the cable 6.

[0041] like Figure 7As shown, the towing cable mechanism 4 includes a mounting frame 403 arranged in the winch frame 1, and the guide frame 401, the towing cable wheel 402 and the towing cable driving device 405 are all arranged on the mounting frame 403, wherein a spring core shaft 4011 is provided in the middle of the guide frame 401, a core shaft guide seat 4031 is provided on the mounting frame 403, and the upper end of the spring core shaft 4011 can be lifted and inserted in the core shaft guide seat 4031, and the spring core shaft 4011 is covered with a guide frame spring 4012, and the guide frame spring 4012 is provided between the core shaft guide seat 4031 and the guide frame 401.

[0042] like Figures 7-8 As shown, a plurality of cable pressing wheels 404 are provided on one side of the mounting frame 403 along the circumferential direction of the upper side of the towing wheel 402, and a plurality of cable pressing elastic components are provided on the other side of the mounting frame 403, and the cable pressing wheels 404 are connected to the cable pressing elastic components one by one. Fig. 9 As shown, in this embodiment, the cable compression elastic component includes a cable compression wheel frame 4041, a vertical axis frame 4045 and a cable compression wheel spring 4044, wherein the wheel axle of the cable compression wheel 404 passes through the mounting frame 403 and is fixedly connected to the corresponding cable compression wheel frame 4041, the mounting frame 403 is provided with a slide groove 4032 for the movement of the wheel axle, the vertical axis frame 4045 is fixedly mounted on the mounting frame 403, and a vertical axis 4042 is fixedly mounted on the vertical axis frame 4045, a pressure plate 4043 is provided on the upper part of the vertical axis 4042, a support plate 40411 is provided at the lower end of the cable compression wheel frame 4041, and the vertical axis 4042 passes through the support plate 40411, and the cable compression wheel spring 4044 is sleeved on the vertical axis 4042 and is arranged between the support plate 40411 and the pressure plate 4043.

[0043] When the present invention is working, under the action of the cable pressing wheel spring 4044, the cable 6 can be pressed by the cable pressing wheel 404, so that friction force is generated on the contact surface between the cable 6 and the towing wheel 402, and then the cable 6 can be recovered and released by the rotation of the towing wheel 402. When the cable is collected, the towing cable driving device 405 can adjust the rotation speed of the towing wheel 402 according to the load change, so as to control the constant tension of the cable 6 between the towing wheel 402 and the cable storage drum 201, and further ensure the orderly arrangement of the cable 6 on the cable storage drum 201. When releasing the cable, the towing cable driving device 405 drives the towing wheel 402 to rotate in the opposite direction, and uses the friction force generated by the cable pressing wheel 404 to provide the cable 6 with a drag force to separate from the cable storage drum 201. In addition, when start-stop, control lag, etc. occur, cable 6 will be prone to loosening, shaking, etc. due to the short-term sudden change in tension, which will affect the orderly arrangement of the cable. Therefore, the present invention uses the towing cable guide wheel 4013 on the guide frame 401 to elastically contact the cable 6 downward and provide a constant and continuous external force in the downward direction. When the tension of cable 6 changes suddenly, this external force can make up for the tension loss, thereby avoiding loosening or shaking of cable 6. It is particularly suitable for complex ocean current environments in the deep sea (2000 meters depth) and can ensure the reliable operation of the present invention in deep sea environments.

In this embodiment, the clamping drive device 503 and the cable cutting drive device 504 can use hydraulic cylinders.

When the deflection angle of the cable 6 is greater than the set threshold, the equipment system controls the lead screw driving device 207 to start, and then drives the slide 204 to move in the direction of reducing the deflection angle of the cable 6 until the deflection angle of the cable 6 returns to the set range, and then the lead screw driving device 207 stops running. The present invention controls the discharge of the cable 6 through the cable arrangement assembly independent of the cable storage drum 201, thereby ensuring the orderly arrangement of the cables 6 on the cable storage drum 201.

[0052] The cable 6 passes around the cable steering guide wheel 302 in the cable guide mechanism 3 and then enters the towing cable mechanism 4, wherein the cable steering guide wheel 302 and the code disk 303 in the cable guide mechanism 3 rotate synchronously, when the code disk tooth 3031 blocks the proximity switch 3011, the proximity switch 3011 is in an on state, and when it is not blocked, it is in a off state. The present invention determines the installation spacing of the two proximity switches 3031 based on the tooth pitch of the code disk teeth 3031, thereby ensuring that the two proximity switches 3031 cannot be turned on or off at the same time when the code disk 33 rotates, thereby determining whether the rotation of the cable steering guide wheel 302 is reversed. In addition, the present invention can also obtain the rotation speed of the cable steering guide wheel 302 by detecting that the proximity switch 3011 continuously sends an on / off signal, thereby monitoring the speed of cable 6 retraction and release, and the axle pin force sensor 3012 is used to detect the tension of the cable 6 in real time.

[0053] After entering the towing cable mechanism 4, the cable 6 bypasses the guide frame 401 and the towing cable wheel 402 in sequence, and the towing cable wheel 402 is driven to rotate by the towing cable driving device 405 to realize the towing operation. When the cable is collected, the towing cable driving device 405 can adjust the rotation speed of the towing cable wheel 402 according to the load change, so as to control the constant tension of the cable 6 between the towing cable wheel 402 and the cable storage drum 201, and further ensure the orderly arrangement of the cable 6 on the cable storage drum 201. When releasing the cable, the towing cable driving device 405 drives the towing cable wheel 402 to rotate in the opposite direction, and uses the friction force generated by the cable pressing wheel 404 to provide the cable 6 with a towing force to separate from the cable storage drum 201. In addition, when start-stop, control lag, etc. occur, cable 6 will easily become loose, shake, etc. due to the short-term sudden change in tension, thereby affecting the orderly arrangement of the cable. Therefore, the present invention utilizes the towing cable guide wheel 4013 on the guide frame 401 to elastically contact the cable 6 downward and provide a constant and continuous external force in the downward direction. When the tension of cable 6 changes suddenly, this external force can make up for the tension loss, thereby preventing the cable 6 from loosening or shaking.

[0054] The cable 6 is outputted by the cable towing mechanism 4 and passes through the docking seat 501 of the docking mechanism 5. During the cable laying and cable retracting operations, the cable 6 is guided by the cable guide cylinder 502 and the inserting cylinder portion 5051 of the guide disk 505 to prevent the cable 6 from moving in a large range. When the cable 6 is completely recovered (when the equipment is docked), the connector 601 first enters the guide disk portion 5052 of the guide disk 505, and then enters the inserting cylinder portion 5051 along the conical surface of the guide disk portion 5052. Then, the connector lock blocks 5031 on both sides are driven to move by the clamping drive device 503 to clamp and lock the connector 601. In addition, when an emergency occurs, the cable cutting drive device 504 starts and drives the cutter 5041 to move and cut the cable 6 to achieve the self-throwing function.

[0055] The present invention integrates various mechanisms into a winch frame 1, which can realize the overall transfer of the equipment with high integration. In addition, the present invention can maximize the cable storage space of the cable storage drum 201 inside the winch frame 1 through the layout design of various mechanisms, thereby meeting the cable storage length requirements (for example, when the designed operating water depth is 2000 meters, the cable storage length can reach 7000 meters). In addition, in addition to controlling the rotation speed through the drum drive device 203, the present invention also uses the cable steering guide wheel 302, the code disk 303, the proximity switch 3011, etc. for real-time monitoring, and at the same time uses the towing wheel 402, the guide frame 401 and other structures in the towing cable mechanism 4 to achieve constant tension and tension compensation of the cable 6, thereby ensuring that the cables 6 on the cable storage drum 201 are arranged in order, and the above structure is not affected by the complex environment of the deep sea, has high reliability and can ensure intelligent control performance.
