Referring to fig. 1-6, the fish-leaking grille A21 fully considers the shape and size of fish in design, and fish gathered in the culture cabin during fishing pass through the fish-leaking grille orderly, so that the fish-sucking pipeline is prevented from forming scratch and even a gambling pipeline between the fish.
Referring to FIG. 8, the water leakage cover plate c is made of a nontoxic and odorless polypropylene material having a density of 0.87kg/dm 3 In order to prevent the water from floating to the water surface after being installed, a proper amount of balancing weights are only required to be installed on the water leakage cover plates, so that the total density of each water leakage cover plate is slightly higher than that of the seawater for cultivation, and divers can install and carry the water in the cultivation cabin conveniently.
Referring to fig. 1 and 7, the bottom surface of the bottom row outer ring a2 is an annular inclined surface bottom, and the lowest part of the inclined surface bottom is smoothly connected with the bottom of the fish sucking interface.
Referring to fig. 1 and 7, an escalator for a shipman to climb down to overhaul is fixedly arranged on the inner wall of the bottom row inner ring a1.
Referring to fig. 2, the fish sucking cover plate b includes two fan-shaped cover plates with different sizes, namely a large cover plate b1 and a small cover plate b2, wherein the large cover plate b1 is provided with 4 blocks, and the small cover plate b2 is provided with 2 blocks.

Referring to fig. 8, a weight c7, a locking ring c8, a latch c91 and a stopper c94 are mounted on the water leakage cover plate c by bolts.
The bottom row system at the bottom of the culture cabin is an important interface for realizing the exchange between the fish culture water body and the seawater around the industrial ship, and is also an important channel for capturing the fishes collected downwards by the culture cabin.
The fish-leakage cover plate is shown in fig. 7 and 8: when the fish in the fishing net is completely caught, the fish sucking cover plate on the bottom drain fish grid is required to be detached and replaced by the water leakage cover plate. After the water leakage cover plate is installed in place, the culture water in the culture cabin is discharged out of the culture cabin to clean the fish which is caught by the water leakage cover plate. When the water level in the culture cabin drops to the vicinity of the net cover, the forced-draining pump is closed to prevent the net cover from being damaged or damaged due to uneven stress caused by the suction of the forced-draining pump, residual culture water in the ballast pump culture cabin is started to enter a cavity formed by the bottom-draining inner ring, the bottom-draining outer ring and the inclined plate through the water leakage cover plate, then the culture cabin is discharged through the ballast water system pipeline through the ballast water port, after all the culture seawater in the culture cabin is discharged, a culture worker enters the bottom of the culture cabin to pick up the fish out of the net when the fish is gathered, and the fish is conveyed to a designated area.
Referring to FIGS. 1 and 7, the mesh enclosure has a selected density of 0.87kg/dm 3 The polypropylene, the material of rings, handles, twist grips and clamping bars of all components on the net cover is 316L.
The whole set of fish sucking cover plate b consists of four large cover plates b1 and two small cover plates b2. When the fish is collected and caught, the installation number of the fish sucking cover plates b installed on the fish leakage grid is adjusted as shown in the installation schematic diagrams of the fish sucking cover plates in figures 3, 4 and 5, so that the fish sucking and catching system catches fish in an optimal state of fish water in the fish sucking process, thereby not only damaging the fish as little as possible in the fish catching process, but also catching the fish in the net to a designated point as fast as possible. In addition, the fish sucking cover plate b is made of a relatively thin steel plate for carrying; in order to be convenient to install, the fish sucking cover plate b can be installed in place by pressing the fish sucking cover plate b and the fish leakage grating with force after the fish sucking cover plate b and the fish leakage grating are aligned. When the fish-leaking grille is disassembled, the handle on the fish-sucking cover plate is pulled by force.
After the fishing and sucking of the lower gathered fish is completed, the fish sucking cover plate b is completely detached from the water leakage cover plate to take out the culture cabin, then the water leakage cover plate is placed in the culture cabin, the water leakage cover plate c is placed on a bottom row of fish leakage grid by a diver, and the installation schematic diagram 8 shows that: the handles on all the bolts c9a of the water leakage cover plate c are supported and rotated for 90 degrees in the locking ring c8 inserted in sequence, then the handles on the bolts c91 are placed between the limiting rings c92 on the bolt bottom plate, and the water leakage cover plate is installed in place. Because each culture cabin has a culture water body of about 6000m, a small amount of fish leaking from the culture cabin cannot be avoided when the fish is gathered under the net, and after the fish gathering is completed, the culture water in the culture cabin is required to be completely discharged out of the culture cabin, and then the fish leaking from the culture cabin is cleaned. In the early stage of the discharge of the culture water in the culture cabin, the culture seawater forced-drainage pump is required to be started for quick discharge, and when the culture water level in the culture cabin is discharged to the vicinity of the upper edge of the net cover, the net cover is damaged in order to avoid the suction of the forced-drainage pump, so that the culture seawater forced-drainage pump is required to be closed. The rest of the culture seawater in the culture cabin is required to be started to be pumped by a ballast water pump to be discharged out of the cabin, the culture seawater in the process firstly enters a cavity formed by the inner ring of the bottom row, the outer ring of the bottom row and the inclined plate through the water leakage cover plate, and then flows through a ballast water system pipeline through a ballast water port to be discharged out of the culture cabin.
The foregoing is a preferred embodiment of the present invention, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed invention.
