Fish school detection unmanned ship

Abstract

The invention provides a fish school detection unmanned ship, and belongs to the technical field of fish school detection. The fish school detection unmanned ship comprises an unmanned ship and a detection device, wherein the detection device comprises a device body, a fixing rod and two auxiliary detection mechanisms, an annular groove is formed in the device body, the fixing rod is fixedly arranged at the bottom part of the annular groove, a first sleeve is arranged on the fixing rod in a sliding mode, a first detection radar is arranged on the fixing rod, each auxiliary detection mechanismcomprises a plurality of rotating rods, a first linkage structure and a plurality of second linkage structures, the rotating rods are movably arranged in the annular groove in the radial direction through the rotating structures, second sleeves are arranged on the rotating rods in a sliding mode, second detection radars are fixedly arranged on the rotating rods, the first linkage structures can change the angles between the fixed rods and the rotating rods, and the second linkage structures can change the angles between every two adjacent rotating rods. The detection direction and the detection area of the detection device can be adjusted as required, and the detection efficiency of the unmanned ship is improved.

Description

technical field [0001] The invention belongs to the technical field of fish detection, and relates to an unmanned fish detection ship. Background technique [0002] Large-scale seine farming has a large space, a natural environment, and high-quality aquaculture products, and has gradually become a new model and main force for high-end marine aquaculture. [0003] Due to the large water area of ​​the large-scale purse seine culture, there is a large space for the activities of the cultured objects. When feeding, an unmanned ship with a fish detector is used to navigate in the cultured waters to detect the activities of the cultured objects. Since there is no The fish detectors commonly used on manned boats have low detection accuracy and require a long detection time, and it is difficult to accurately grasp the activity locations and foraging rules of the breeding objects; The device can't find the catch position quickly, which is time-consuming and labor-intensive.
