Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Example 1

As shown in fig. 1-3, a net cage capable of conveniently capturing fish includes a fishing net cage 6, main piles 1 and auxiliary piles 2, the main piles 1 are symmetrically inserted at two sides of the fishing net cage 6, the auxiliary pile 2 is inserted at one side of each main pile 1, the auxiliary piles 2 are connected with the main piles 1 through high-strength long stay ropes 4, pulleys 3 are installed at one side of each main pile 1 through installation rods, a net control rope 5 is installed at the periphery of each pulley 3 through a rope placing groove, one end of the net control rope 5 is respectively connected with the top corners of the frame of the fishing net cage 6, specifically, the four top corners of the fishing net cage 6 are connected with the net control rope 5, and a lantern ring 14 is arranged at the end of the net control rope 5 far away from the frame of the fishing net cage 6; the 6 frames of fishing net cage are from last to dwindling down in proper order, and are equipped with first filter screen 7 and second filter screen 8 in the 6 frames of fishing net cage, and the 7 meshes of first filter screen are greater than the 8 meshes of second filter screen, the mesh of the 6 remaining dictyosomes of fishing net cage is the same with the mesh size of second filter screen 8, and second filter screen 8 is equipped with the end net that must mouthful 13 and must mouthful 13 pass fishing net cage 6 along the must mouth of falling of passageway direction, and 6 end net limit portions of fishing net cage evenly are equipped with sinker 9, and sinker 9 is the rectangle, and the welding of rectangle sinker 9 top has lifting

hook

8, and 8 tops of lifting hook pass through the 6 end nets of fishing net cage of high strength short stay cord 12 connection.

Wherein, the vertical distance L1 between the upper end opening of the first filter screen 7 and the fishing net box 6 and the vertical distance L2 between the first filter screen 701 and the second filter screen 8 are in the proportion of 2:1, a certain space difference is formed, and fish is primarily screened by setting different meshes.

Wherein, the high-strength long pull rope 4, the high-strength short pull rope 12 and the net control rope 5 are all made of nylon materials, the sinker 9 is made of stainless steel materials, and the fishing net cage 6 is made of polyethylene materials.

It should be noted that the utility model relates to a net cage capable of conveniently catching fish, when in operation, the breeding personnel insert 4 main piles 1 into the tank in the feeding area 3-4 m in front of the feeding machine to form a 'caisson area' with a long side of 7 m and a wide side of 3 m, and insert 4 auxiliary piles 2 and tie the main piles 1 by using high-strength long stay ropes 4 in the place 4-5 m away from the main piles on the opposite bank of the hauling net or the tank, so as to prevent the main piles from being inclined under the stress of the fishing net cage 6; during fishing, the aquaculture personnel sink the fishing net cage 6 fastened with the inverted beard opening 13 in a feeding area before operation, then start a feeding machine in the aquaculture pond, when fish species are clustered, 2 aquaculture personnel can rapidly pull 4 net control ropes 5 passing through the pulleys 3 from two sides by taking the lantern rings 14 as acting points, rapidly pull up the fishing net cage 6 and fasten the fishing net cage 6 (the concrete fastening mode can be that the fishing net cage 6 is fixed on the ground and then fastened by taking the lantern rings 14 as locking points), meanwhile, along the fishing moment, fish with relatively small specifications can enter the second filter screen 8 along the first filter screen 7, and the fish with smaller specifications can directly return to the water after the clustering, so that the extrusion is avoided from influencing the quality of the fish, and next, the fish on the first filter screen 7 can be directly fished, weighed and sold from the upper side after about 20 minutes, and the inverted beard opening 13 of the artificial fish supporting boat in the second filter screen 8 is used for weighing and selling, after fishing, weighing and selling are finished, 2 breeders release the net control rope 5 in the hands, so that the rectangular sinkers 9 at the edge of the bottom net of the fishing net cage 6 pull the fishing net cage 6 to sink to the bottom of the aquaculture pond, the stocking operation of aquatic offspring seed clusters is completed, and the operation is very convenient.
