LIFTING-DIVING SELF-POWERED ADJUSTING APPARATUS FOR EUPHAUSIA SUPERBA BEAM TRAWL

摘要

A lifting-diving self-powered adjusting apparatus for a Euphausia superba beam trawl, the lifting-diving self-powered adjusting apparatus comprising lifting-diving adjusting devices (2) symmetrically installed on a beam (1). The lifting-diving adjusting device (2) comprises a fairing (3), a protective cover (4), a propeller water flow generator (5), a two-way driving electric motor (6), a rotating screw rod (7), a lifting connecting member (8) and a wing (9), wherein the protective cover (4) is connected to a rear end of the fairing (3); the propeller water flow generator (5) is installed inside the fairing (3); the two-way driving electric motor (6) is supplied with power by the propeller water flow generator (5); the rotating screw rod (7) is installed on the protective cover (4) in a bidirectional rotating manner along two vertical ends; the rotating screw rod (7) is driven by the two-way driving electric motor (6) to rotate; the lifting connecting member (8) is assembled on the rotating screw rod (7) by means of a thread structure; and a front end of the wing (9) is horizontal, two sides thereof are rotationally connected to the protective cover (4) separately, and a rear end of the wing (9) is connected to the lifting connecting member (8) and driven by the lifting movement of the lifting connecting member (8) to adjust the angle thereof. The adjusting apparatus can achieve controllable and self-powered active lifting-diving adjustment of the beam trawl.
