Problems solved by technology

The key technology of this system lies in the speed synchronization control and tension limitation between the traction winch and the cable storage winch; Irregular, damaged or even broken; 2. If the tension control is not appropriate, it will not be able to protect the tow cable; 3. Especially when the cable storage winch has many layers of tow cable or the tension of the tow cable changes greatly when encountering severe sea conditions, This type of equipment cannot

Abstract

The invention discloses a cable storage winch capable of achieving accurate regulation of cable winding tension. The cable storage winch comprises a capstan, a magnetic powder clutch, a rack, a driving motor and a speed reducer; the rack is provided with the capstan, and a roller on one side of the capstan is provided with the magnetic powder clutch; the magnetic powder clutch is in drive connection with a speed reducer shaft; the speed reducer is connected to the driving motor, and the magnetic powder clutch has a slip function; positive and negative poles of the magnetic powder clutch are connected to adjustable power sources used for power supply for the magnetic powder clutch; and the power sources at the two ends of the magnetic powder clutch are provided with circuit breakers. According to the cable storage winch, the cable storage winch in a double-winch winding and unwinding system is driven by the motor, and the magnetic powder clutch is arranged between the speed reducer andthe winch, so that the cable winding tension can be regulated accurately; and the slip function of the magnetic powder clutch can be used for ensuring that the speeds of a towing winch and the cable storage are completely consistent, and the instantaneous speed difference between the towing winch and the cable storage winch is eliminated, so that towing cables can be protected under extreme conditions.

Description

technical field [0001] The invention relates to the field of marine operation or detection equipment retraction system and tow cable laying and erection technical equipment, in particular to a cable storage winch capable of accurately adjusting the tension of the cable. Background technique [0002] The winch is an important marine operation equipment in the marine field. It is mainly used for the implementation of marine operations and the retraction of detection equipment. At present, it is mainly connected with detection equipment, underwater robots and underwater drag bodies. . Because the photoelectric composite cable is expensive, it is easy to be damaged if the cable tension fluctuates greatly during the process of retracting and unwinding the cable. In addition, the winch works on the deck of the ship. The sea wind, waves and ocean currents on the ocean will cause the mother ship to drive the winch up and down. The tension on the cable brings disturbances. Excessive...
