[0052] Embodiment 2:

[0053] The difference between the above embodiment and this embodiment is that: Figure 6 and Figure 7 As shown, the cover plate 202 is formed by a flat plate 2021 and a plurality of pairs of inclined plates 2022 connected in an interlaced manner, and the plurality of pairs of inclined plates 2022 are movably connected end to end and form a wave shape, the inclined plate 2022 on one side is movably hinged with the breeding box 201, and the inclined plate 2022 on the other side is movably provided with a flat plate 2021, and the flat plate 2021 slides on the breeding box 201, and the intersection position at the bottom of the cover plate 202 is movably provided with a positioning slider 2023, and the positioning slider 2023 slides on the positioning chute 2024, and the positioning chute 2024 is opened above the breeding box 201, and the positioning slider 2023 movably connected to the cover plate 202 is installed with a swing arm 2054. When the flat plate 2021 moves, it pulls the plurality of inclined plates 2022 to gradually move horizontally, so that the top of the breeding box 201 can be better covered.

[0054] like Figure 6 and Figure 8As shown, in a specific embodiment, both ends of the screw shaft 203 are mounted on the bearing seat provided on the side wall of the breeding box 201, and a driving motor 2031 is provided at the end of the screw shaft 203, the housing of the driving motor 2031 is fixedly connected to the outer wall of the bearing seat, and a limiting groove 2034 is vertically provided on the side wall of the breeding box 201, and a limiting slider 2033 is slidably provided inside the limiting groove 2034, and a screw ring 2032 is fixedly provided inside the limiting slider 2033. When the driving motor 2031 is started, the connected screw shaft 203 is driven to start rotating by the driving motor 2031, and a screw ring 2032 is meshedly provided on the screw shaft 203, and the limiting slider 2033 on the screw ring 2032 slides inside the limiting groove 2034 to limit the screw ring 2032, so that the screw ring 2032 drives the top plate 2035 to move upward.

[0055] like Figure 6 and Figure 8 As shown, further, a fixed block is installed on the side wall of the scraper 2041, and a limit rod 2042 is movably provided inside the fixed block, and both ends of the limit rod 2042 are fixedly connected to the protrusions provided on the side wall of the breeding box 201, and the end of the side plate 204 is vertically corresponding to the top block 205. The side plate 204 continues to move upward, pushing the scraper 2041 of the side wall to move upward, and the scraper 2041 always slides on the limit rod 2042, ensuring that the scraper 2041 can always move along the water inlet 2011, scraping off the waterweeds blocking the surface of the water inlet 2011, and ensuring the fluidity of the internal water.

[0056] Embodiment 3:

[0057] The difference between the above embodiment and this embodiment is that: Figure 6 and Figure 8 As shown, the top block 205 is slidably arranged on the inner groove 2051, the inner groove 2051 is opened on the side wall of the breeding box 201, the inner groove 2051 is in a vertical state, a guide rod 2052 is vertically penetrated inside the inner groove 2051, the top block 205 is slidably arranged on the side wall of the guide rod 2052, a return spring 2053 is slidably arranged on the guide rod 2052, one side of the return spring 2053 is clamped with the inner wall of the inner groove 2051, and the other side of the return spring 2053 is mutually clamped with the top block 205. The side plate 204 can eventually contact the top block 205, and the top block 205 moves upward along the guide rod 2052 at this time, and can squeeze the return spring 2053 on the surface, so that the return spring 2053 facilitates the return operation of the top block 205 in the later stage.

[0058] like Figure 3 , Figure 4 and Figure 5As shown, in a specific embodiment, the clamping rod 403 and the cover plate 202 correspond horizontally, an outer ring 4031 is fixedly arranged on the outer wall of the clamping rod 403, a limit seat 4032 is arranged in the inner cavity of the side wall of the breeding box 201, and the limit seat 4032 and the clamping rod 403 are movably plugged, and an extrusion spring 4033 is clamped between the outer ring 4031 and the limit seat 4032. A transmission shaft 4011 is fixedly arranged on the side wall of the flip cover 401, and the transmission shaft 4011 movably penetrates the side wall of the fish outlet 2012, and the end of the transmission shaft 4011 is fixedly connected to the central axis of the driving gear 4012. When the cover plate 202 moves, it can come into contact with the card rod 403, and the inclined surface of the card rod 403 is squeezed by the cover plate 202. At this time, the card rod 403 begins to slide downward, the outer ring 4031 of the card rod 403 moves downward, and the card rod 403 slides along the limit seat 4032. At this time, the installed extrusion spring 4033 is compressed, and the extrusion spring 4033 is used to facilitate later resetting. The card rod 403 moves downward, driving the driven rack 402 to move downward, and then driving the driving gear 4012 of the side wall to rotate. The rotation of the transmission shaft 4011 drives the flip cover 401 to rotate and open from the fish outlet 2012. During the upward movement of the top plate 2035, the fish is pushed to move upward, and finally can be discharged from the fish outlet 2012, thereby improving the catching efficiency.

[0059] The present invention also discloses a temporary rearing method of a large water surface fish storage and water hanging system, the steps are as follows;

[0060] Step 1: Place the fish to be cultured in the culture box 201 on the water-based floating platform 101, and ensure that the fish in each culture box 201 have a suitable culture density;

[0061] Step 2: Start the screw shaft 203, and drive the screw ring 2032 and the top plate 2035 to slide upwards through the screw shaft 203. The top plate 2035 slides upwards to reduce the space inside the breeding box 201, thereby ensuring a suitable breeding density. When the top plate 2035 moves upwards, the breeding water depth inside the breeding box 201 changes at the same time, which is suitable for breeding different types of fish.

[0062] Step 3: During the movement of the screw ring 2032, the scraper 2041 on the side wall moves synchronously along the water inlet 2011, so that the scraper 2041 can clean the water weeds blocking the surface of the water inlet 2011;

[0063] Step 4: Start the stirring motor 301, and drive the rotating shaft 302 and the synchronous bracket 3011 to rotate through the stirring motor 301, thereby driving the entire breeding box 201 to rotate, continuously delivering new water to the inside of the breeding box 201, ensuring the oxygen content of the water in the breeding box 201, and the rotation of the rotating shaft 302 can also drive the rotation of the flow fan blades 3021, and the rotation of the flow fan blades 3021 drives the water body to flow faster, thereby increasing the speed of water replacement.

[0064] The implementation principle of a large-surface fish storage and water lifting system and its temporary breeding method of this embodiment is as follows: the fish to be farmed are placed inside the breeding box 201 on the water-based floating platform 101 to ensure that the fish inside each breeding box 201 has a suitable breeding density.

[0065] During the temporary rearing process, the stirring motor 301 drives the rotating shaft 302 and the synchronous bracket 3011 to rotate, thereby driving the entire breeding box 201 to rotate, continuously delivering new water to the inside of the breeding box 201 to ensure the oxygen content of the water in the breeding box 201, and the rotation of the rotating shaft 302 can also drive the circumferential flow blades 3021 to rotate. The rotation of the circumferential flow blades 3021 drives the water body to flow faster, thereby increasing the speed of water change and improving the survival rate of the temporarily reared fish.

[0066] When the temporary rearing is completed, the temporarily reared fish need to be caught as a whole. At this time, the operator needs to start the drive motor 2031, and the drive motor 2031 drives the connected screw shaft 203 to start rotating, and a screw ring 2032 is meshed on the screw shaft 203, and the limiting slider 2033 on the screw ring 2032 slides inside the limiting groove 2034 to limit the screw ring 2032. Therefore, at this time, the screw ring 2032 drives the top plate 2035 to move upward, and the upward sliding of the top plate drives the space inside the breeding box to become smaller, ensuring a suitable breeding density, and when the top plate moves upward, the breeding water depth inside the breeding box changes at the same time, which is suitable for breeding different types of fish.

[0067] When the top plate 2035 continues to move upward, the side plate 204 of the side wall always moves upward, and the side plate 204 can finally contact the top block 205. The top block 205 moves upward along the guide rod 2052 at this time, and can squeeze the return spring 2053 on the surface, and the return spring 2053 facilitates the top block 205 to perform a reset operation later. When the top block 205 moves, the position of the swing arm 2054 is driven to change, and the swing arm 2054 pushes the cover plate 202 at the end to move as a whole, which can seal the top of the breeding box 201 and reduce the loss caused by the fish crossing the breeding box. The flat plate 2021 on the cover plate 202 moves, pulling a number of inclined plates 2022 to gradually move horizontally, which can better cover the top of the breeding box 201.

[0068] The side plate 204 continues to move upward, pushing the scraper 2041 of the side wall to move upward, and the scraper 2041 always slides on the limit rod 2042, ensuring that the scraper 2041 can always move along the water inlet 2011, scraping off the aquatic plants blocking the surface of the water inlet 2011, and ensuring the fluidity of the internal water.

[0069] When the cover plate 202 moves, it can come into contact with the card rod 403, and the inclined surface of the card rod 403 is squeezed by the cover plate 202. At this time, the card rod 403 begins to slide downward, the outer ring 4031 of the card rod 403 moves downward, and the card rod 403 slides along the limit seat 4032. At this time, the installed extrusion spring 4033 is compressed, and the extrusion spring 4033 is used to facilitate later resetting. The card rod 403 moves downward, driving the driven rack 402 to move downward, and then driving the driving gear 4012 of the side wall to rotate.
