Description

Technical Field

[0001] The utility model relates to the technical field of underwater equipment, and particularly relates to an automatic cable releasing device for an ROV winch. Background Art

[0002] A remotely operated underwater vehicle (ROV) is an underwater robot used for underwater observation, inspection, and construction. An ROV winch is a winch device used for retrieving and lowering an ROV. It can realize the lowering and recovery of the ROV and its connecting cable (umbilical cable) through the rotation of a drum, enabling the ROV to reach a specific underwater depth for operation.

[0003] Generally, when the ROV winch releases the cable, the power source may be the power of the ROV to draw out the cable, or manual extraction, or other auxiliary components, with a complex structure. However, relying on the power of the ROV to draw out the cable will affect the action posture of the ROV. Manual extraction wastes manpower and increases the number of operators. In some specific situations such as high-voltage electricity inside the umbilical cable, it may even endanger the personal safety of the operators. Summary of the Invention

Specific embodiments

[0022] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and attached Figures 1-6 The content mentioned in the embodiments is not a limitation to the present utility model.

The cable outlet roller 3 is installed in the sliding frame 1 through a rotating shaft. The electromagnetic clutch 2 is sleeved on one side of the cable outlet roller 3 (when the electromagnetic clutch 2 is energized and attracted, the power of the driving motor 4 is transmitted to the cable outlet roller 3 to draw out the umbilical cable. When power is cut off, the cable outlet roller 3 can rotate freely to facilitate the smooth passage of the umbilical cable during cable retraction). The driving motor 4 is fixed on one side of the sliding frame 1. The reduction gearbox 5 is fixed on the outer side wall of the sliding frame 1, and one end of the reduction gearbox 5 is connected to one end of the rotating shaft, and the other end of the reduction gearbox 5 is connected to the power output end of the driving motor 4 (the reduction gearbox 5 can be used to adjust the speed and torque of the driving motor 4). The first cable guiding rollers 6 are uniformly arranged at the upper end of the sliding frame 1.

[0024] In this embodiment, the ROV winch automatic cable laying device further includes two groups of wire pressing mechanisms 7. The wire pressing mechanisms 7 are respectively arranged at both ends of the sliding frame 1 and can rotate relatively.

[0025] In this embodiment, the wire pressing mechanism 7 includes wire pressing rollers 71, a bracket, and an elastic member 74. One end of the bracket is movably mounted on the sliding frame 1. The wire pressing rollers 71 are sleeved on the other end of the bracket. One end of the elastic member 74 is fixed to the sliding frame 1, and the other end of the elastic member 74 is fixed to one end of the bracket close to the wire pressing rollers 71. The elastic member 74 is preferably a torsion spring.

[0026] The rov winch automatic cable laying device in this embodiment has a simple structure, low production cost, and reliable structure. At the same time, it realizes automatic cable payout, is convenient and fast to use, and saves manpower and material resources. During operation, it needs to be used in cooperation with a winch with an automatic cable laying function. When in use, the lead screw 9 and the optical axis 8 of the winch cooperate to support the cable laying device, so that it can move axially under the drive of the lead screw 9. The first cable guiding roller 6, the second cable guiding roller 10, the cable payout roller 3, and the wire pressing rollers 71 cooperate with each other to guide the umbilical cable, enabling it to wind and payout smoothly on the reel and maintaining a certain arrangement order. The wire pressing rollers 71 and the cable payout roller 3 press the umbilical cable under the action of the torsion spring. The driving motor 4 drives the cable payout roller 3 to rotate, and the cable can be drawn out. The electromagnetic clutch 2 can be engaged during cable payout to transmit the power of the driving motor 4 to the cable payout roller 3 to realize the cable payout action. When the winch is taking in the cable, the electromagnetic clutch 2 is disengaged, so that the cable taking-in roller can rotate freely along its own rotating shaft, thereby reducing the resistance and enabling the umbilical cable to pass through smoothly.

[0027] In this embodiment, the bracket includes a fixed shaft 72 and a rotating member 73. Both ends of the fixed shaft 72 are fixed to both sides of the sliding frame 1 and are located inside the sliding frame 1. One end of the rotating member 73 is sleeved on one end of the fixed shaft 72 and can rotate relative to the fixed shaft 72. The wire pressing rollers 71 are fixed to the other end of the rotating member 73. One end of the elastic member 74 is fixed to the other fixed shaft 72, and the other end of the elastic member 74 is fixed to the connection between the rotating member 73 and the wire pressing rollers 71.

[0028] In this embodiment, the wire pressing rollers 71 and the bracket are used to cooperate with the cable payout roller 3 to press the umbilical cable to increase the friction between the umbilical cable and the cable payout roller 3, facilitating the extraction of the umbilical cable. The torsion spring can provide a pressing force for the wire pressing rollers 71 and the rotating member 73.

[0029] In this embodiment, the sliding frame 1 is provided with first mounting holes 11 penetrating through its two side walls. Bearings 12 are sleeved in the first mounting holes 11 to facilitate the rotation of the bearings 12. Both ends of the rotating shaft are respectively sleeved in the first mounting holes 11 and can rotate relative to the first mounting holes 11.

A linear bearing 15 is penetrated through the second mounting hole 13, and a lead screw nut 16 is penetrated through the third mounting hole 14.

[0031] In this embodiment, the second mounting hole 13 is used for sleeving a light shaft 8. The light shaft 8 penetrates through the linear bearing 15 and both ends of the light shaft 8 extend out of the second mounting hole 13. The setting of the linear bearing 15 enables the automatic cable laying device to slide left and right along the light shaft 8.

[0032] In this embodiment, the third mounting hole 14 is used for sleeving a lead screw 9. The lead screw 9 penetrates through the lead screw nut 16 (the lead screw nut 16 can convert the rotational motion of the lead screw 9 into an axial linear motion for driving the automatic cable laying device to move axially). Both ends of the lead screw 9 extend out of the third mounting hole 14, and the light shaft 8 and the lead screw 9 are arranged in parallel to jointly support the automatic cable laying device. By rotating the lead screw 9, the automatic cable laying device can be driven to move axially along the drum to wind the cable to a proper position to achieve neat cable laying.

[0033] In this embodiment, second cable guide rollers 10 are provided at both the linear bearing 15 and the lead screw nut 16. The second cable guide rollers 10 are clamped inside the sliding frame 1, and one end of each second cable guide roller 10 is fixed to the inner side wall of the sliding frame 1.
