Example Embodiment
[0044] Embodiment 2: The trawl with multiple sets of pockets in parallel of this embodiment 2 includes a net wing, a net body and a net bag. The net wing is connected with a fishing boat connected to the trawl, and the net bag is installed at the rear end of the net body. Connected to the net body, a telescopic cylinder is installed in the longitudinal rod of the front frame of the bag. The telescopic cylinder is connected to the controller. When the front frame of the bag needs to be opened, the controller controls the extension of the telescopic cylinder, and the cylinder overcomes the The retracting force of the elastic element drives the longitudinal rods to extend. The upper and lower bars of the front frame separate to form an expanded pocket. The fish caught by the trawl can enter the pocket through the frame and be collected. If reset is required, the controller controls The telescopic cylinder retracts and drives the upper cross rod to reset. At the same time, the elast...
