摘要:
The present invention provides a fish hoisting apparatus that reduces or suppresses the influence of sways resulting from both pitch and roll of the vessel on the operation of drawing and hoisting a fishing device. The fish hoisting apparatus of the present invention comprises: a rotary drum, mounted on the vessel for lifting and lowering the fishing device; a driving mechanism, which drives the rotary drum to rotate; a detection mechanism, which detects the away speed in an vertical direction resulting from the pitch of the vessel and a sway angular speed of the rotation of a shaft extending in front-rear direction of the vessel resulting from the roll of the vessel; and a control mechanism, which controls the driving mechanism in response to a signal from the detection mechanism. The detection mechanism comprises: a sway speed sensor, which detects acceleration in the vertical direction and outputs a signal indicating the sway speed in the vertical direction; and a sway angular speed sensor, which detects the angular speed of the rotation of the shaft and outputs a signal indicating the sway angular speed. The control mechanism comprises: a drawing correction mechanism, which makes the hoisting speed of the fishing device a variable hoisting speed when the hoisting operation of the fishing device is accompanied with a drawing operation; a pitch correction computation mechanism, which computes a pitch correction value corresponding to the pitch phenomenon based on the signal of sway speed; a roll correction computation mechanism, which computes a roll correction value corresponding to the roll phenomenon based on the signal of sway angular speed; and a speed correction mechanismusing the variable hoisting speed, which is obtained through correction made by the pitch correction and the roll correction and further subjected to the drawing correction mechanism, to eliminate the sway resulting from pitch and roll.本發明係提供一種可減少或抑制船體之縱搖現象及橫搖現象之雙方所致之搖動對漁具之抽動起吊動作造成影響之漁撈用起吊裝置
