With the deep research of submarine electric field generation and propagation characteristic mechanism, ocean electric field detection is applied to long-distance underwater large-scale target detection search, in general, a plurality of electric field sensors are required to be arranged for underwater electric field detection to work simultaneously, a certain distance is required to be arranged between the electric field sensors, and a certain angle is required to be formed between each electric field sensor and a base data processing platform by connecting cables, as if a large-scale antenna for receiving an electric field is arranged underwater. The electric field detection sensitivity is not only related to the detection precision of the electric field sensor, but also related to the arrangement angle of the electric field sensor and the arrangement length of the sensor connecting cable. Therefore, the electric field sensor and the connecting cable can be laid on the seabed according to the requirements of azimuth and length in the electric field sensor laying engineering operation, and the electric field detection cable laying winch device is required to be carried on an underwater vehicle. In addition, the electric field sensor has extremely high detection precision, and electrochemical reaction of a metal structure close to the electric field sensor can cause interference to the electric field detection, so that the electric field sensor is free of metal structures in a short distance after being released, and has certain requirements on long-term storage conditions on land, namely the electric field sensor needs to be soaked in saline water and cannot be exposed to air for a long time, so that the sensitivity of the electric field sensor is prevented from being reduced.
At present, the electric field sensor and the connecting cable are mainly distributed by dragging and placing the electric field sensor and the connecting cable by a water surface ship, the base data processing platform is distributed on the sea bottom, and then the electric field sensor and the connecting cable are released to the water bottom after being dragged to a distribution point along a designated direction by the ship on the water surface. This arrangement has several problems:
1. the length of a connecting cable between a general electric field sensor and a base data processing platform is about hundred meters, the water depth is hundreds of meters, and the accurate fixed-point arrangement of the electric field sensor is difficult to realize by dragging the connecting cable by a rope by a water surface ship;
2. the cable diameter of the connecting cable between the electric field sensor and the base data processing platform is generally smaller, the tensile strength is smaller, and the connecting cable is very likely to be broken by dragging the connecting cable by a water surface ship, or the base data processing platform is dragged, so that a larger potential safety hazard of equipment exists;
