Detailed Description

Referring to fig. 1 to 8, after a ship enters a port dock to be berthed, a ship position monitoring system of a general control station measures the accurate position of the ship and instructs each winch to loosen a cable, instructs the cable dragging mechanism a1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the inflatable bag 26 of the cable dragging mechanism D4 to inflate, causes the cable dragging mechanism a1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the cable dragging mechanism D4 to float from the seabed to the sea surface, instructs the rudders 28 and the propellers 31 of the cable dragging mechanisms a1, the cable dragging mechanism B2, the cable dragging mechanism C3, the cable dragging mechanism D4, the cable dragging mechanism E5 and the cable dragging mechanism F6 to work, each cable dragging mechanism drags a respective cable to a position of the ship, instructs the respective ship suction cups 27 of the cable dragging mechanisms to be electrified to suck the shells of electromagnets of the respective winches, and then instructs the respective winches to tighten or loosen the cables to be matched with each other, dragging the ship to a designated position, when the ship needs to be shifted in the process of loading and unloading goods, similarly instructing each winch to tighten or loosen the cable by the master control console to move the ship to the designated position, instructing each winch to tighten the cable when the ship needs to be driven away after loading and unloading goods, and dragging each cable dragging mechanism to the initial position by each cable, particularly dragging the cable dragging mechanism A1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the cable dragging mechanism D4 to the side of each anchor pier and releasing the air of the inflatable bag 26 of each anchor pier, so that the cable dragging mechanism A1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the cable dragging mechanism D4 do not influence the normal running of the ship; when the winch F25 tightens the cable, the winch 40 rotates clockwise to withdraw the cable E15 and wind it on the winch 40, at the same time, the composite tube 41 fixed on the winch 40 pulls the wire releasing wheel 42 to rotate counterclockwise, at the same time, the composite tube 41 wound on the wire releasing wheel 42 slides along the rollers 43 and winds it on the winch 40, at this time, the outlet end of the composite tube 41 wound on the wire releasing wheel 42 will not release the wire because of the counterclockwise rotation of the wire releasing wheel 42 because of the left pulling force; when the winch F25 loosens the cable, the winch 40 rotates counterclockwise to pay out the cable E15, and the paying-off wheel 42 rotates clockwise to wind the composite pipe 41 wound on the winch 40 on the paying-off wheel 42, and the working principle of other winches for tightening and loosening the cable is identical to the working principle.

Need to explain: when the ship needs to be driven away after loading and unloading goods, the general control console instructs each winch to tighten the cables, each cable dragging mechanism is dragged to the initial position by each cable, particularly the cable dragging mechanism A1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the cable dragging mechanism D4 are dragged to the side of each anchor pier, if the air-filled inflatable bags 26 of the cable dragging mechanism A1, the cable dragging mechanism B2, the cable dragging mechanism C3 and the cable dragging mechanism D4 do not affect the passing of other ships, the inflatable bags 26 do not need to be deflated, and when the cable dragging mechanisms perform the mooring work of the next ship, the cables can directly float out of the sea surface by directly loosening the cables; the propeller 31 of the cable dragging mechanism bears the forward power of the cable dragging mechanism, and the cable bears the backward power of the cable dragging mechanism; the propeller 31 of the cable dragging mechanism only drags the cable and the cable, and the power of the cable dragging mechanism is small, so that the cable dragging mechanism can be designed to be small and exquisite, and the cost of the cable dragging mechanism is reduced; the through hole 36 of the balloon 26 is used for restraining the transverse movement of the cable 19 and the cable, and meanwhile, the cable 19 and the cable restrain the transverse movement of the balloon 26; the function of the payout rumbles 42 is to retract the composite tube 41 to facilitate connection of the subsequent electrical cable 19 to the corresponding equipment.
