Classifying and fishing device for fishes of different specifications in natural water area

Abstract

The invention relates to the technical field of fish catching equipment, in particular to a classifying and fishing device for fishes of different specifications in a natural water area, which comprises buoys, motors are fixedly mounted at the tops of the inner walls of the two buoys through bolts, and electric push rods are welded to the output ends of the motors. The defects in the prior art are overcome, through motor operation and connection of two bevel gears and other components, threaded rods are matched to drive square plates to ascend and descend, water in the buoys is discharged through the square plates, people can conveniently control the buoyancy of the buoys according to the use requirements, the buoys are conveniently hidden in water at ordinary times, and lawbreakers are prevented from stealing fishes in the device by observing the buoys; when connecting ropes are pulled, rubber inclined rings can pump out part of residual water in sealing grooves like needle cylinder rubber plugs, so that the tops of the inner walls of the buoys are waterproof, multiple effects of pulling a fishing net rack and adjusting the buoyancy of the buoys and the like can be achieved on the whole by using only one motor, and the applicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of fish fishing equipment, in particular to a fish classification and fishing device with different specifications in natural waters. Background technique [0002] Natural waters are naturally formed waters within a range. Oceans, rivers, lakes and swamps are all natural bodies of water. People often use fishing gear to catch fish in natural waters. The ocean, which accounts for about 2 / 3 of the earth's surface area, has always been the main place for fishing. The world's ocean fishing production generally accounts for about 90% of the total fish catch, and inland waters account for about 10%. Marine fishing can be divided into coastal, offshore and pelagic (including offshore) operations. Coastal and offshore waters are rich in aquatic animal resources, and the unit catch is relatively high; ocean fishing is far away from the base, requires high fishing equipment and technology, low resource density, and...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sorting and fishing device for fish of different sizes in natural waters, which overcomes the deficiencies of the prior art and aims to solve the problem of the inability to classify and fish fish of different sizes and specifications and the inability to fish The problem of more convenient process
