为了适应海洋调查研究,或其他测量领域的需要,上海第七○四研究所五室对改善电缆绞车测量信号传递的精确度和可靠性,进行了深入的研究。现有的电缆绞车,电讯号传递都是用导电滑环有接触地传递给仪器,对仪器工作性能有不良影响,或传递信号微弱时仪器无法工作,这种现象在电缆移动过程中传递信号时尤为明显。为了解决这个问题,苏联人提出了动静双卷筒绕线式水文绞车,它由静卷筒、动卷筒和绕线传动系组成。动卷筒上电缆的一端与研究仪器的发讯部分连接,另一端引向静卷筒,绕在静卷筒上,再从静卷筒接向仪器的接收部 In order to meet the needs of marine survey and research or other surveying fields, Room # 704 of Shanghai No.704 Research Institute conducted an in-depth study on improving the accuracy and reliability of cable winch measurement signal transmission. The existing cable winch and signal transmission are all transmitted to the instrument in contact with the conductive slip ring, which has an adverse effect on the working performance of the instrument or the instrument can not work when the signal is transmitted weakly. This phenomenon is transmitted during the movement of the cable Especially obvious. In order to solve this problem, the Soviets put forward the static and dynamic double-drum winding hydrographic winch, which consists of a static drum, moving drum and winding drive train. One end of the movable drum is connected with the sending part of the research instrument, and the other end leads to the static drum, which is wound on the static drum, and then connected to the receiving part of the instrument from the static drum
