The invention belongs to the field of power equipment, and particularly relates to a double-layer winding drum capstan and winch facilitating heat dissipation of an umbilical cable, which comprises a frame body, an inner-layer winding drum, an outer-layer winding drum and a locking mechanism, a rotating mechanism is arranged at one end of the frame body, a clutch is arranged at the other end of the frame body and connected with an external driving rotating device, and a spraying pipe is arranged on the frame body; one end of the inner-layer winding drum is connected with the rotating mechanism, and the other end of the inner-layer winding drum is rotationally connected with a lead screw through a fixed shaft; the outer-layer winding drum movably sleeves the inner-layer winding drum and is in threaded connection with the lead screw, and a heat dissipation interval is formed between the outer-layer winding drum and the inner-layer winding drum; and the locking mechanism is used for locking and fixing after the inner-layer winding drum and the outer-layer winding drum are overlapped. Due to the fact that the heat dissipation interval is formed between the outer-layer winding drum and the inner-layer winding drum, heat dissipation efficiency can be improved, water sprayed out of the spraying pipe can be sprayed to the outer-layer winding drum and can also enter the heat dissipation interval, and the heat dissipation efficiency is further improved.
本发明属于电力设备领域,具体涉及一种有利于脐带缆散热的双层卷筒绞盘及绞车,包括架体、内层卷筒、外层卷筒和锁死机构;架体一端设置有转动机构,另一端设置有离合器,离合器与外部的驱动转动装置连接,架体上设置有喷淋管;内层卷筒一端与转动机构连接,另一端定轴转动连接有丝杠,丝杠的一端与离合器对接并与架体定轴转动连接;外层卷筒活动套设于内层卷筒并与丝杠螺接,外层卷筒与内层卷筒之间具有散热间隔;锁死机构用于内层卷筒与外层卷筒重叠后锁紧固定。由于外层卷筒与内层卷筒之间具有散热间隔,能够提高散热效率,并且喷淋管喷出的水不仅喷淋到外层卷筒还能够进入散热间隔,进一步地提高了散热效率。
