In another embodiment, a second type of cable cutting pliers 44 is provided, with a flat angle between the handle 441 and the blades 444, so that the two blades 444 are arranged crosswise.
The blades 444 of the second cable shearing pliers 44 are arranged in a crossed mode, shearing force is large, and the cable 6 is easy to shear.
The opposite end of blade 444 is the shear end; when the two follower gears 413 move in opposite directions, the shearing ends of the two blades 444 are away from each other; when the two follower gears 413 are moved toward each other, the shearing ends of the two blades 444 come close to each other to commonly cut the wire 6.
For the second type of cable cutting pliers 44, the two follower gears 413 move back to back, the cable cutting pliers 44 open, the angle between the two blades 444 is enlarged, and the two blades 444 are in an idle station; the two follower gears 413 move in opposite directions, the cable cutter 44 performs a cutting action, reducing the angle between the two blades 444, and the two blades 444 are in the cutting station.

Step 102, when the tension is higher than a set high tension threshold, controlling the cable recovery device 3 to recover the cable 6;
specifically, when the tension is higher than the high tension threshold, the controller 10 controls the cable recovery device 3 to recover the cable 6.
Step 103, monitoring the recovery length of the cable 6 and judging whether the recovery length of the cable 6 is smaller than a preset length threshold;
specifically, the cable retrieving device 3 records the retrieving length of the cable 6, and the controller 10 determines whether the retrieving length is smaller than a preset length threshold.
If so, the ship 1 needs to stand by at a fixed point, and waits for the control platform 9 to send out a cable shearing signal, and if the ship 1 continues to move the traction force of the cable 6, the equipment or the ship body is damaged. When the recovery length is greater than the length threshold, it is indicated that the cable 6 does not have problems such as bottom hanging or winding, and the tension of the cable is continuously monitored so as to find out the problems of the cable 6 in time.
If not, continuing to monitor the tension of the cable.
And 104, controlling the cable cutting device 4 to perform cable cutting operation when the recovery length of the cable 6 is smaller than a preset length threshold.
The cable cutting method can be used for the ship 1, when the tension is higher than the high tension threshold, the cable 6 has the risk of hanging or winding, the cable 6 is recovered to verify whether the cable 6 is hung or wound, and if the length threshold cannot be recovered, the problem of hanging or winding of the cable 6 is verified. In order to avoid damage to equipment or a ship body caused by traction force of the cable 6, cable shearing request information is sent to the control platform 9, and an operator of the workbench sends a cable shearing agreement signal according to actual conditions, so that the cable shearing device 4 performs cable shearing operation. Before the ship 1 sends the cable cutting request information, the recovery length and the length threshold value are compared specifically; when the recovery length is less than the length threshold, the ship 1 stands by at a fixed point, as shown in fig. 5, after step 103, before step 104, the method further comprises the steps of:
step 201, sending cable cutting request information to the control platform 9;
step 202, receiving cable cutting indication information sent by a control platform 9;
in step 203, if the cable cutting instruction information is the agreeing cable cutting information, the cable cutting device 4 is controlled to perform the cable cutting operation.
The operator needs to judge whether to perform cable cutting operation or not based on the condition of the ship 1; if the control platform 9 sends a signal of agreeing to cut the cable to the ship 1, the cable cutting operation is executed; otherwise, the ship 1 stands by at fixed points.
The operator needs to judge whether cable cutting operation is needed according to the monitored site specific conditions, if the cable cutting operation is not needed, the ship 1 stands by at fixed points for the site investigation and operation of staff or waits for the tension of the cable 6 to be lower than a low tension threshold.
In another embodiment, the vessel 1 comprises an unmanned vessel, and the cable cutting method may also be applied to an unmanned vessel, which is also capable of sending cable cutting request information to the control platform 9 via the satellite 8. Specifically, the unmanned ship transmits cable shearing request information to the control platform 9 through the satellite 8 by the communication equipment on the ship.
If the operator agrees to cut the cable, the operator operates the control platform 9 to send an agreeing to cut the cable signal to the unmanned ship through the satellite 8. Specifically, the operation console sends a signal for agreeing to cut the cable to the signal transmission unit 2 of the unmanned ship via the satellite 8, and after the signal transmission unit 2 receives the signal, the cable cutting equipment is controlled to cut the cable.
After the cable cutting device 4 performs the cable cutting operation, monitoring the tension of the cable and judging whether the tension is smaller than a preset low tension threshold; if the tension is smaller than the preset low tension threshold, the cable cutting device 4 stops the cable cutting operation. If the tension of the cable 6 is less than the high tension threshold, indicating that the cable 6 is cut, stopping the cable cutting action. The ship cable cutting system, the cable cutting equipment and the ship cable cutting method provided by the embodiment of the application can be applied to a ship 1 or an unmanned ship so as to cope with the situation that manual intervention is difficult when the ship 1 or the unmanned ship encounters complex terrains such as jatropha or cliff when operating in a water area. The cable is cut and need not manual operation, guarantees personnel's safety, saves personnel and reaches the required manpower and the time cost of spending of operating point processing, convenient and fast to when cable 6 retrieves when being obstructed among the prior art, need cut cable 6 by the manual work, very waste time and energy and have the technical problem of potential safety hazard.
