Collecting device for survey of fishery resources

Abstract

The invention relates to an acquisition device for fishery resource investigation and an acquisition method thereof, the acquisition device comprises a base, a top seat and a power seat, the top seat is mounted on the top of the base, a plurality of buoyancy airbags are mounted on the outer side of the base, the power seat is mounted on the bottom side of the base, and a camera and a plurality of multi-parameter water quality sensors are mounted on the top of the top seat; the water pump works, the control valve is in an open state, water is sucked into the adjusting cavity, the piston in the adjusting cavity is driven to move, air in the adjusting cavity is pressed into the buoyancy air bag on the periphery of the base, the control valve is closed, the water pump stops working, the overall mass of the device is changed, and the device is immersed in water. The depth of the device in water is adjusted according to the amount of water sucked into an adjusting cavity, meanwhile, a second waterproof motor works to drive the device to move and rotate, information in water is collected through a camera and a multi-parameter water quality sensor, information collection of fishery at different water depths is achieved, and actual operation and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of fishery equipment, in particular to a collection device for fishery resource investigation. Background technique [0002] Fishery, also known as aquaculture, refers to the production sector that uses waters to obtain fish or other aquatic animals and plants with economic value; it includes two types of fisheries, fishing for aquatic animals and plants, and aquaculture for cultivating aquatic animals and plants. In part, the information located underwater is collected by the collection device. [0003] The existing collection devices for fishery resources survey have limited depth of information collected, and can only be used in shallow waters, which has certain limitations in the actual application process. As a result, the device cannot be recovered, and at the same time, it is difficult to retrieve the device that has suddenly lost connection. SUMMARY OF THE INVENTION [0004] The problem solved by...

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a collection device for fishery resources investigation, which solves the problem that the existing collection device for fishery resources investigation has a limited depth of collected information and can only be used in shallow sea waters. Certain limitations; at the same time, for complex waters, aquatic plants often entangle, which leads to the failure of the device to be recovered. At the same time, it is difficult to find the technical problem of the device that suddenly loses connection.
