Fishing net cage position finder and fishing safety protection system thereof

Abstract

The invention provides a fishing net cage position finder which comprises a fishing net cage. The fishing net cage comprises an upper fixed ring and a lower fixed ring, four protection plates are arranged between the upper fixed ring and the lower fixed ring, separation nets are arranged among the four protection plates, a limit ring is arranged in the upper fixed ring, a threaded groove is formedin the inner side wall of the limit ring, a cover plate is spirally arranged on the limit ring, a feeding pipe is arranged on the cover plate, one end of the feeding pipe penetrates the cover plate,a positioner is arranged at the other end of the feeding pipe and comprises a floating pipe, a hollow cylindrical buoy body is arranged on the floating pipe, a cover is arranged on the cylindrical buoy body, and a storage battery and a circuit board are arranged in the cylindrical buoy body. The invention further provides a fishing safety protection system of the fishing net cage position finder which can monitor real-time states of ships and fishing net cages and improve safety of the fishing net cages and ship navigation.

Description

technical field [0001] The invention relates to the technical field of fishery breeding, in particular to a fishnet cage locator and a fishery safety protection system thereof. Background technique [0002] At present, most of the existing net cages in my country are floating type, which are cultivated near the shore, and have poor wind and wave resistance. The breeding sites are limited to bays or harbor basins with good sheltered conditions. , the accumulation of pollution, the worsening of the breeding environment, the frequent occurrence of fish diseases, and the continuous decline of breeding benefits have seriously hindered the development of fish culture in sea cages. In addition, the existing fishnet cages do not have the function of positioning. If the fishnet cages are under the condition of relatively strong wind and waves, the fishnet cages may move along the sea water, so that the position of the fishnet cages on the seabed is unknown, which leads to the work of ...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the existing net cages in my country are floating type, which are cultivated near the shore, and have poor wind and wave resistance. Their breeding sites are limited to bays or harbor basins with good sheltered conditions. , the accumulation of pollution, the deterioration of the aquaculture environment is becoming more and more serious, the occurrence of fish diseases is frequent, and the efficiency of aquaculture is declining, which seriously hinders the development of fish culture in sea cages.

In addition, the existing fishnet cages do not have the function of positioning. If the fishnet cages are under the condition of relatively strong wind and waves, the fishnet cages may move along the sea water, so that the position of the fishnet cages on the seabed is unknown, which leads to the work of breeding in the early stage. all in vain

In addition, when the fishing net box is placed irregularly, the fishing net box drifts, or the yaw of the passing ship, the fishing net box may be entangled by the ship's propeller, which will have a great impact on the safe navigation of the ship and cause huge economic losses to the fishermen.
