Technical Field

The invention belongs to the technical field of ocean engineering equipment, and particularly relates to a device for detecting stress of a net piece and a purse seine using the device.

Background

The widespread use of advanced technologies and the over-utilization of marine resources by people has led to the rapid depletion of offshore marine fishery resources, and shallow sea farming has been vigorously developed in recent years. In shallow sea culture, purse net culture or deep water cage culture is commonly used, under the condition of heavy stormy waves, the purse net or the cage is difficult to resist or certain impact occurs to cause damage of netting/the cage, and the damage of the netting cannot be found in time, so that a great amount of fish escapes to cause huge loss. Therefore, the safety problem of the netting is one of the key problems to be solved in shallow sea culture. The following measures are commonly adopted for monitoring the damage of the netting abroad: 1, an underwater camera which can rotate by 360 degrees and can ascend and descend is arranged in the center of the net cage to scan the netting, but the method cannot be used in muddy water environment. 2. The underwater robot with the camera crawls along the netting to transfer the surface condition of the netting to the water surface monitoring room, and the underwater robot can be used for muddy water. However, the crawling speed of the robot is slow, and the robot and the netting may be wound to damage the netting. 3. In the sonar mode, when the netting is damaged and fish escapes, sound wave reflection images in the internal area and the external area of the net cage are obviously changed, and the defect that the damaged part cannot be determined is overcome. The common disadvantages of the above 3 methods are: the system has high energy consumption, needs personnel to monitor and has high development, operation and maintenance costs.
