Technical Field

The invention belongs to the technical field of aquaculture equipment, and relates to a connection structure of a crab pot, in particular to a connection structure of the crab pot and a culture rope.

Background

the crab is a crustacean of decapod order, brachypodium order, and the crab has many kinds, most of which can be eaten, and the crab shell can be used for extracting industrial raw material chitin and glucosamine. The crab larva or adult can be used as bait and feed; the crabs mainly comprise portunus trituberculatus, portunus pelagicus, blue crabs, Chinese mitten crabs and the like; the crab cage is adopted to breed the crabs, which becomes an important and mature breeding means; the portunus trituberculatus has more meat, is fat and beautiful and has rich nutrition, is an important economic crab in coastal areas of China, and is also a main fishing object of fishing boats for crab pot fishing operation in China. When the crab pot fishing boat catches, the cage unloading ring section in the crab pot pulling process is mainly finished in a manual mode; about 3000 crab pots need to be unloaded each time when the crab pot is pulled up, the number of the unloaded crab pots per minute is about 26, each crab pot is about 2Kg, and 4 professional cage unloading personnel are needed to alternately operate in the crab pot pulling-up link. The crab pot fishing boat is used for taking up and putting out the cages approximately 4 times every day, people need to hook and unhook about 12000 times, the labor intensity of workers is very high, in addition, the fishing period of the crab pot fishing boat is mainly in summer, and personal safety accidents such as misoperation caused by heatstroke and fatigue are very easy to happen to fishermen due to high-temperature and high-intensity labor. At present, 3000-4000 crab pots are required to be recovered by one-time operation of a crab pot fishing boat, and only about 22 crab pots can be recovered per minute, so that the labor intensity of crab pot collecting work is very high, the time consumption is long, and the cost is very high. Moreover, the high-strength work easily causes people fatigue, and in addition, the people are close to the side of the ship during the work, so that the falling accident is easy to happen.

In order to reduce the cost and improve the safety of fishery production, a device which can automatically detach and recover the crab pot from the breeding rope needs to be designed to replace manpower.

Chinese patent (publication number: CN 105908402A; publication date: 2016-08-31) discloses an automatic crab pot gripping device, wherein the crab pot comprises an upper frame ring, a lower frame ring and vertical ribs, the vertical ribs are distributed at intervals along the circumferential direction of the upper frame ring and are connected with the upper frame ring and the lower frame ring, the gripping device comprises a gripping mechanism and an upper and lower driving mechanism, the upper and lower driving mechanism is connected with the gripping mechanism, and the upper and lower driving mechanism can drive the gripping mechanism to move up and down; snatch the mechanism and include base, push pedal, a horizontal drive unit and a plurality of clamping jaw subassembly, clamping jaw unit mount is between base and push pedal, and all clamping jaw subassemblies all set up along the even interval of circumference of base, one of them clamping jaw subassembly and push pedal fixed connection, surplus clamping jaw subassembly and push pedal sliding connection, drive all clamping jaw subassemblies radially expand outward through the radial translation of horizontal drive unit drive push pedal and prop the gripping that tightly realizes the crab pot with the last frame circle of crab pot.

The automatic crab pot gripping device in the patent document has a complex structure, high manufacturing cost and inconvenient use. Although the single crab pot does not need to manually open the lock catch of the hook, the connection structure design of the crab pot and the breeding rope is inconvenient for using electromechanical equipment to automatically disassemble and take a large number of crab pots, and the aquatic product capturing efficiency is influenced.
