Figure 1 The fishing net 300 is arranged in the cylinder 210 of the fish gathering cylinder 200, and the horizontal fish gathering mechanism 500 and the vertical fish gathering mechanism are arranged in the frame 100. When the device is fishing, the vertical net 510 on the horizontal fish gathering mechanism 500 is firstly moved to the side close to the fish gathering cylinder 200 (corresponding to the side close to the fish gathering cylinder 200). Figure 1 The vertical fish gathering mechanism is at a preset water depth, and then the horizontal net 410 on the vertical fish gathering mechanism is driven to move downward or upward. Since the opening on the cylinder 210 is opened, the fish enter the cylinder 210 of the fish gathering cylinder 200 from the frame space of the frame 100 through the opening under the action of the vertical driving mechanism. A catching net 300 is also provided in the cylinder 210, and the catching net 300 can move up and down in the cylinder 210 to catch live fish. That is to say, the novel live fish catching device of the embodiment of the present invention first gathers the fish school through the horizontal fish gathering mechanism 500, then drives the vertical fish gathering mechanism at the preset water depth to move up and down to compress the movable space of the live fish, and opens the opening on the fish gathering cylinder 200 to allow the fish school at the preset water depth to enter the cylinder body 210, and finally catches the live fish with the catching net 300, which can realize layered catching and improve the survival rate of the caught live fish.

[0082] Furthermore, the horizontal fish gathering mechanism 500 further includes a second guide seat 580 and two second rollers 590. The second guide seat 580 is disposed at the end of the connecting rod 512. The second guide seat 580 forms a second cavity with both ends passing through. The two second rollers 590 are disposed in the second cavity. There is a second gap between the two second rollers 590. One end of the second guide steel rope 513 is connected to the top connecting rod 512, and the other end passes through the second gap and is connected to the sliding trolley 530 through the sliding seat 550. In other words, Figure 4-Figure 5 As shown, the vertical net 510 passes through the second guide steel rope 513, the sliding seat 550, and the connecting sliding trolley 530 in sequence, and a second guide seat 580 is also provided on the connecting rod 512 of the vertical net 510.

The mounting seat 230 is arranged on the cylinder body 210 above the corresponding position of the opening. The connecting seat 240 is arranged on the movable cover plate 220 at a position corresponding to the mounting seat 230. The driving unit 250 is a telescopic oil cylinder. One end of the telescopic oil cylinder is pivotally connected to the mounting seat 230, and the other end is pivotally connected to the connecting seat 240. The telescopic oil cylinder can be extended / contracted to drive the movable cover plate 220 to close / open. In other words, if Figure 6As shown, a plurality of openings (not shown in the figure) are provided in the height direction of the fish gathering tube 200, so that the movable cover plate 220 at any of the openings can be controlled to open, thereby catching the live fish in the water layer corresponding to the opening. Furthermore, by providing the movable cover plate 220 at the opening, the movable cover plate 220 is driven by a telescopic oil cylinder. When the horizontal fish gathering mechanism 500 gathers the fish school to the surrounding water area of ​​the fish gathering tube 200, the vertical fish gathering mechanism at a predetermined position moves upward or downward to gather the fish school, thereby gathering the live fish living in the preset water layer, and then the movable cover plate 220 corresponding to the depth of the water layer is driven to open by the telescopic oil cylinder, so that the live fish enter the cylinder 210 of the fish gathering tube 200 through the opening. After all the live fish enter the cylinder 210, the telescopic oil cylinder drives the movable cover plate 220 to close, which can avoid the accidental fishing caused by other live fish entering the cylinder 210, and further improve the survival rate of the live fish. Finally, after the live fish enters the cylinder 210, the fish can be sucked onto the fishing boat by a fish suction pump connected to the fish suction pipe 260 of the cylinder 210.
