Specific embodiment

As shown in Figure 1,5, a kind of fish-catching apparatus 1, including fishpot 2, the elevator for going up and down fishpot 2 in water Structure, the fish inlet 3 being located on fishpot 2, the gate 4 being located at fish inlet 3 and the floating body 5 connecting with gate 4, floating body 5 sink When can drive gate 4 close fish inlet 3, floating body 5 float when can drive gate 4 open fish inlet 3.The top opening of fishpot 2, Fishpot 2 includes spacer screen 8 and side net 15.Hoisting mechanism is air bag 6 or elevating mechanism hand, and preferred air bag 6 herein, air bag is equipped with Gas tube 12 passes through the lifting of control fishpot 2 inflatable and deflatable into air bag 6.

The following are two kinds of specific embodiments:

The specific structure of first embodiment is as follows, and as shown in Figure 1, 2, air bag 6 is arranged in 2 bottom of fishpot, the side net of fishpot 2 15 to be equipped with multiple be in the fish inlet 3 being distributed vertically, and equipped with gate 4 at each fish inlet 3, gate 4 is hinged on side net 15 Top at fish inlet 3, and gate 4 is hinged on the inner wall of side net 15, floating body 5 is connect with the gate 4 of top layer；In same perpendicular It is connected between the gate 4 being directly distributed by connecting rod 7.Spacer screen 8 is obliquely installed, and the lower end of spacer screen 8 is formed with 15 intersection of side net unloads Lymphogranuloma inguinale 9.

Fish-catching apparatus 1 uses this kind of structure, as shown in figure 4, fish inlet 3 and gate 4 are located on the side net 15 of fishpot 2, As shown in Fig. 2, floating body 5 floats in water drives the unlatching of top layer's gate 4, the zone of action of the gate 4 of top layer due to connecting rod 7 The gate 4 of dynamic lower section is opened simultaneously.It is acted on as shown in figure 3, leaving 5 loss of buoyance of floating body after water body, gate 4 is driven to make in gravity With lower closing.After fishpot 2 is promoted to outside the water surface, opening unloads lymphogranuloma inguinale 9, and the fish captured can unloading by 8 lower end of spacer screen Lymphogranuloma inguinale 9 carries out operation of unloading fishes.

The specific structure of second embodiment is as follows, as shown in figure 5, air bag 6 and fish inlet 3 are arranged in 2 bottom of fishpot, catches Bottom in fish pot 2 corresponds to and is equipped with several guide rods 10 around fish inlet 3, and gate 4 is equipped with and guide rod 10 is matched leads Hole, the top of guide rod are equipped with limited block 13, and floating body 5 is connect by rope 14 with gate 4.Spacer screen 8 is set with 15 intersection of side net It sets and unloads lymphogranuloma inguinale 9.

Fish-catching apparatus 1 in water fishing operation when, floating body 5 is floated by buoyancy, and gate 4 is upward along guide rod 10 Sliding, fish inlet 3 is opened, when fishing operation finishes, floating body 5 leave water surface late gate 4 under the effect of gravity along guide rod 10 to Lower slider closes fish inlet 3.

Further, as shown in Figure 1, being surrounded by several vertical gag lever posts 11 outside fishpot 2, gag lever post 11 surrounds limit Bit space, fishpot 2 are located in limit space and go up and down under the action of hoisting mechanism, and the fishing of fixed point centralization may be implemented Operation.

In addition, fishpot 2 is placed in water the present invention also provides a kind of fishing method, utilize hoisting mechanism or floating body In water by the floating of fishpot 2, it drives gate 4 to open the fish inlet 3 being located on fishpot 2 when floating body 5 floats and carries out fishing work Industry；It promotes fishpot 2 and leaves the water surface, drive gate 4 to close into fish when 5 loss of buoyance of floating body on fishpot 2 acts on and sinks Mouth 3.

By using above-mentioned fish-catching apparatus 1 and fishing method, the beneficial effect reached is to pass through air bag 6 or elevator Tool hand controls 2 raising and lowering of fishpot, and gate 4 is driven to close fish inlet 3 when sinking by floating body 5, and floating body 5 drives when floating Gate 4 opens fish inlet 3, and the automatic shutter of fish inlet 3 is realized with this, in entire fishing operation, can save significantly on manpower, Structure is simple.

Especially apply in marine fishing field, by the large-scale fish-catching apparatus 1 of fixed point sea area setting and with fishing The vertical gag lever post 11 that device 1 matches, goes up and down fishpot 2 in the limit space that gag lever post 11 surrounds, may be implemented Pinpoint centralization fishing operation, and due to fishing boat and fish-catching apparatus 1 be it is separated, only a fish storehouse need to be set on fishing boat, Fish is directly poured into Yu Cang by unloading lymphogranuloma inguinale 9 after wait catch, it is convenient and efficient, and working environment is significantly improved, it avoids The serious destruction that generates to seabed ecology of seine fishing is injured caused by fish in mitigation fishing operation, and realize fixed point, It is large-scale to concentrate fishing operation.

Furthermore it is possible to according to the life waters range and Larger water depths of fish, in catching for different fishing point setting different heights Fish pot 2, and different baits targetedly is launched into fishing boxes and baskets 2, targetedly caught.
