Description

Technical Field

[0001] The invention belongs to the technical field related to fishery resource investigation equipment, and specifically relates to a collection device for fishery resource investigation. Background Art

[0002] Fishery resources refer to the total amount of economic animals and plants such as fish, crustaceans, shellfish, algae and marine mammals in natural waters that have development and utilization value. They are the natural source and foundation of fishery production. Also known as aquatic resources, surveys on the reproduction, growth, death, migration, distribution, quantity, habitat, prospects for development and utilization, and means of economic animals and plants in waters are the basic work for the development of fisheries and the management of fishery resources. They are divided into two categories: management surveys and development surveys. The former is conducted on developed fishing grounds, aiming to rationally utilize aquatic resources to obtain the maximum reasonable and sustainable output. The latter is conducted on undeveloped waters, aiming to find new fishing targets and corresponding development means. The information to be provided after the survey includes: ① the population composition of fishable species and other aquatic economic animals and plants within a specific water area; ② the time and location of the population distribution in the water area; ③ the number of fishable populations or the degree of development; ④ the appropriate technology and means for development; ⑤ the necessary production methods and suggestions for rational development of production; ⑥ opinions on the restoration and rational utilization of over-exploited resources, etc. The quality of fishery resource surveys depends on a large amount of marine survey data to provide information about the circulation and biological distribution range of the world's oceans. For example, the dense distribution of fish on the continental shelf and the high seas is often closely related to the intersection of different currents and the convergence of the surface of the upwelling basin; fish in offshore and estuary areas are also related to the intersection and river runoff. Therefore, the analysis of oceanographic and hydrological data is an important aspect of fishery resource surveys.

[0003] The existing collection devices for fishery resource surveys have limited depth of information when used, and can only be applied to shallow waters, which has certain limitations in actual application. At the same time, in complex waters, water plants often get entangled, making the device unrecoverable. At the same time, it is difficult to find a device that suddenly loses contact.

[0004] For example, a collection device for fishery resource investigation and a collection method thereof disclosed in publication number CN114655371A include a base, a top seat and a power seat, wherein the top seat is installed on the top of the base, and a plurality of buoyancy air bags are installed on the outside of the base, the power seat is installed on the bottom of the base, and a camera and a plurality of multi-parameter water quality sensors are installed on the top of the top seat; when the water pump works, the control valve is in an open state, water is sucked into the regulating chamber, the piston in the regulating chamber is driven to move, and the air in the regulating chamber is pressed into the buoyancy air bags around the base, at this time, the control valve is closed, and the water pump stops working, at this time, the overall mass of the device changes and is immersed in water, and the depth of the device in the water is adjusted according to the amount of water sucked into the regulating chamber, and at the same time, the second waterproof motor is driven to move and rotate the device, and the information in the water is collected through the camera and the multi-parameter water quality sensor, so as to realize information collection of fisheries at different water depths, which is convenient for practical operation and application;

[0005] However, there are still some problems: 1. Although the device can cut the aquatic plants through the circular cutting knife to prevent the aquatic plants from entangled with the entire device, it is unable to predict the aquatic plants, so when the device sinks to a densely populated area with aquatic plants, the aquatic plants will still be entangled; 2. The camera can only perform horizontal video acquisition, while the actual acquisition work is performed at different specified depths, so the camera of the device cannot complete multi-directional video acquisition.
