| description | The present invention relates to a metalimnion adjusting beam structure for a euphausia superba trawl, including a beam, a forward drive hydrodynamic generating mechanism, a reverse drive hydrodynamic generating mechanism, a transmission mechanism, and a rising-diving adjusting wing mechanism. The transmission mechanism includes a transmission shaft, the transmission shaft rotates in opposite directions respectively through non-synchronous drive of the forward drive hydrodynamic generating mechanism and the reverse drive hydrodynamic generating mechanism, the rising-diving adjusting wing mechanism includes installation plates, first gears and a wing plate with a shuttle-shaped cross section, the two first gears are respectively installed on opposite sides of the installation plates at equal heights and at interval, second gears are arranged on the transmission shaft, the second gears are located between the two first gears and synchronously mesh with the two first gears, the wing plate is installed between the installation plates, each end of the wing plate is connected with the two first gears, and an angle of the wing plate can be adjusted through rotation of an axis of the transmission shaft driven by reverse rotation of the two first gears. The present invention can realize controllable and active rising-diving adjustment of a beam trawl. |
