[0001] The invention relates to the technical field of fish fry placing devices, in particular to a large-surface ecological fishery breeding fish fry placing device. Background Art

[0002] Ecological fishery is a sustainable fishery development model based on ecological principles and systems engineering approaches. It emphasizes achieving a harmonious balance of economic, ecological, and social benefits by optimizing the biodiversity structure, material circulation, and energy flow within aquaculture systems. Aiming to achieve "resource conservation, environmental friendliness, and product safety," it aims to reduce over-reliance on natural resources and ecological damage, and is a key direction for the transformation of traditional fisheries toward modern and sustainable development.

[0003] However, manual release is not only inefficient, but the fry are also very likely to produce stress reactions due to drastic changes in the environment when they are directly put into the water, resulting in a significant reduction in survival rate. At the same time, the hydrological conditions of the river are complex and the water contains mud and sand. Some fry release devices lack the adaptive adjustment function to the water flow environment and cannot effectively filter out impurities such as mud and sand in the water, which easily causes the fry release environment to deteriorate and even the release device to become clogged, greatly affecting the growth and survival of the fry. In order to solve the above problems, the present invention proposes a large-scale water surface ecological fishery aquaculture fry release device. Summary of the Invention

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 7 As shown, the present invention provides the following technical solutions: Embodiment 1: A large-scale ecological fish farming fry releasing device comprises a support frame 1, a chute is provided on one side of the support frame 1, a threaded rod 2 is rotated on the inner wall of the chute, a nut is threadedly connected to the outer wall of the threaded rod 2, a support block 3 is fixed to the outer wall of the nut, and the support block 3 extends outside the chute; A first annular block 4 is rotated at the middle position of the upper surface of the support block 3, a second annular block 5 is rotated on the outer wall of the first annular block 4, a third annular block 6 is rotated on the upper surface of the support block 3, a fourth annular block 7 is rotated on the outer wall of the third annular block 6, the interiors of the first annular block 4 and the third annular block 6 are symmetrically penetrated with cavities, the inner walls of the cavities are slid with triangular blocks 8, triangular holes 9 are equidistantly penetrated with the inner walls of the second annular block 5 and the fourth annular block 7, the triangular blocks 8 extend into the triangular holes 9, and a partition plate 10 is fixed to the inner wall of the first annular block 4.

[0019] When in use, the first drive motor 20, the second drive motor 21 and the water flow detector 22 are all connected to the external drive source through the controller, the support frame 1 is fixed in the water surface, the first drive motor 20 is started to drive the threaded rod 2 to rotate, the threaded rod 2 drives the support block 3 to move into the water surface through the nut, and the first annular block 4 is partially immersed in the water surface, the second drive motor 21 is started to drive the rotating rod 12 and the connecting rod 13 to swing, the connecting rod 13 pushes the second annular block 5 and the fourth annular block 7 to rotate through the first push block 15 and the second push block 16, the second annular block 5 rotates outside the first annular block 4, and the fourth annular block 7 rotates outside the third annular block 6, as shown in FIG. Figure 7 As shown, the filter holes 17 and the discharge holes 18 are staggered, the apertures of the filter holes 17 and the discharge holes 18 are reduced, the fry are placed in the first annular block 4, and the partition plate 10 separates the fry, so that the fry can adapt to the dam environment; When the fry are adapted to the water area and released, the second drive motor 21 is started to drive the connecting rod 13 to swing. The connecting rod 13 pushes the second annular block 5 and the fourth annular block 7 to rotate back to their original positions through the first push block 15, so that the filter hole 17 is aligned with the discharge hole 18. Figure 6 As shown, water flows through the filter holes 17 into the first annular block 4, pushing the fry out of the discharge holes 18 to release the fry; During the fish farming period, water flows into the first annular block 4 through the filter holes 17, and the filter holes 17 filter the sediment in the water flow.

The water flow detector 22 monitors the flow rate of the water flow. When the water flow rate is faster, the rotation angle of the fourth annular block 7 and the second annular block 5 is larger, reducing the aperture of the filter hole 17. When the water flow rate is slower, the rotation angle of the fourth annular block 7 and the second annular block 5 is smaller, increasing the aperture of the filter hole 17.

The scraper 14 is against the fourth annular block 7, and the scraper 14 is arranged in a triangular shape, which is convenient for using the scraper 14 to scrape impurities on the surface of the fourth annular block 7 to prevent impurities from clogging the filter hole 17 and affecting the filtering effect of the filter hole 17.

[0021] Among them, a first push block 15 is fixed on the upper surface of the first annular block 4, and a second push block 16 is fixed on the upper surface of the third annular block 6, so that the second annular block 5 and the fourth annular block 7 can be rotated by using the connecting rod 13 through the first push block 15 and the second push block 16.

[0022] Among them, the outer walls of the first annular block 4, the second annular block 5, the third annular block 6 and the fourth annular block 7 are equidistantly penetrated with filter holes 17, and the outer walls of the other ends of the first annular block 4, the second annular block 5, the third annular block 6 and the fourth annular block 7 are penetrated with discharge holes 18. The aperture of the discharge hole 18 is larger than the aperture of the filter hole 17, which makes it convenient to use the filter hole 17 to filter impurities in the water flow and use the discharge hole 18 to discharge the fry.

[0023] Among them, a spring 19 is fixed on the inner wall of the cavity, and the other end of the spring 19 is against the triangular block 8, so that the spring 19 can be used to push the triangular block 8 to move into the triangular hole 9 to limit and fix the second annular block 5 and the fourth annular block 7.

[0024] Among them, a first drive motor 20 is fixed on the upper surface of the support frame 1, and the output end of the first drive motor 20 is fixedly connected to the threaded rod 2 through a coupling, so that the first drive motor 20 can be used to drive the threaded rod 2 to rotate, and the threaded rod 2 drives the support block 3 to move up and down.
