An automatic cage pulling device for cage operation in fishery production

Abstract

The invention relates to an automatic cage pulling device of cage type operation in fishery production. The technical problems that for a traditional fishery cage picking mode, the labor intensity is high, the manpower consumption is large, the technique is high, the cost is high and the risk is high are mainly solved. The automatic cage pulling device of the cage type operation in the fishery production comprises a power source, a trapping cage, a main rope and an unhooking mechanism, the unhooking mechanism comprises a fixed frame, a driving part and a connector, the connector comprises a shell, an elastic part, a lock tongue and an inner core, the shell is provided with a chute which is communicated with an inner cavity of the shell, the lock tongue moves in a sliding mode along the chute, a locking notch is formed on the portion, corresponding to the chute, of the side face of the inner core, the lock tongue is clamped in the locking notch, and the driving part pulls the lock tongue to slide out of the locking notch of the inner core. Due to the fact that the automatic cage pulling device of the cage type operation in the fishery production adopts a mechanical structure to achieve unhooking, the mechanism reliability is strong, the manufacturing cost is low, use of the structure is easy, and the the automatic cage pulling device of the cage type operation in the fishery production is specially suitable for marine fishery production operation; the operation efficiency is greatly improved, the labor production cost is greatly reduced, the operation safety is improved, and the extremely high production benefit and economic benefit are achieved.

Description

technical field [0001] The invention relates to the field of fishery production, in particular to an automatic cage pulling device for cage operation in fishery production. Background technique [0002] In the existing fishery production cage operation, the lifting and pulling of the cage all adopt mechanical lifting and manual lifting of the cage. The specific operation conditions are as follows: Generally, there are about 2,000-10,000 trapping cages (hereinafter referred to as cages) carried by a cage-type operation ship. Each cage is hung on the main rope through a manually detachable connecting hook, and one is hung every 7 meters. For the cage, put the cage into the seabed through the high-speed straight-line sailing of the hull. When pulling out, use the hydraulic starting pump to drive the main rope, and then pull up the cage. Take off the cage hanging on the main rope, put it on the inner deck of the ship, and then release the brake to start the next action. This t...
