Cable winch drum

Abstract

The invention discloses a cable winch drum, which comprises a drum body; the outer circumferential surface of the drum body is axially evenly provided with a plurality of groups of water guide ports communicated with the external of the drum body; outsides of each group of the water guide ports are respectively provided with water guide cases which are fixedly connected with the drum body; two ends of each water guide case are symmetrically provided with water resisting plates slantly; a clearance is reserved between the top of each water resisting plate and the top of each water guide case; and the bottom of each water resisting plate is fixedly connected with the outer circumference of the drum body. The cable winch drum has simple structure, safety and reliability; the water guide ports can make accumulated water in the drum body easily discharged, and external water enter the drum body difficultly; the water guide cases make a cable on the drum overhead to facilitate the drainage and radiating of the cable, and the water guide cases can also improve the rigidity of the whole drum; and the water resisting plates prevent external rainwater or seawater from entering the water guide cases to the utmost degree.

Description

technical field [0001] The invention relates to a cable winch, in particular to a ship slip ring type shore cable winch drum, which belongs to the technical field of ship deck machinery. Background technique [0002] With the continuous development of the shipbuilding industry, deck machinery has been continuously improved. The ship's shore connection cable has also been developed from being scattered in the cabin to being installed in a slip ring type shore connection cable winch, which improves the service life and safety of the cable. The existing ship slip ring type shore cable winch winds the ship shore cable on its drum in an orderly manner. box connected. When the ship is running normally, the outer end of the cable is placed on the drum (the shore power box is not charged when the ship is running normally, so the cable end is also not charged.), when the ship is docked, remove the outer end of the cable from the The roller is pulled out and connected to the power ...

AI Technical Summary

Problems solved by technology

[0003] Due to the structural limitations of the cable winch drum, a high degree of protection cannot be achieved

When the ship is driving on the water or mooring at the shore, it is in a humid environment, and the water vapor will continue to accumulate in the drum. After a period of time, the drum will be full of water, which will cause the insulation level of the equipment to drop. If you want to remove the water, It is necessary to release and remove all the cables on the drum before opening the wiring port cover on the drum to release the accumulated water, which is troublesome to operate

In addition, the cable is wound tightly and orderly on the cylindrical drum. When the cable is soaked by rain or sea water, it is difficult to remove the accumulated water between the cable and the drum. The ventilation and cooling effect of the cable is poor, and the internal heat dissipation is difficult. Affect the service life of the cable and the safety of electricity use
