AI Technical Summary

Technical Problem

In factory-style spawning ponds, parent fish are easily attracted to the spawning port during the spawning process, which leads to poor water exchange and makes it difficult for fertilized eggs to enter the collection tank smoothly.

Method used

Design a protective device including a frame, a filter cover, and bottom corners. The frame is a cylindrical shape welded with steel bars, and the bottom corners are circular ring structures. The filter cover is fitted onto the frame and placed above the spawning opening to prevent the parent fish from adhering to it and to ensure that the fertilized eggs can smoothly enter the egg collection box.

Benefits of technology

It effectively prevents parent fish from being sucked onto the spawning port, while ensuring that fertilized eggs can smoothly enter the egg collection box. It is easy to operate, has a reasonable structural design, and performs well.

Description

TECHNICAL FIELD

[0001] The utility model relates to the equipment technical field for fishery production hatching, especially relates to a spawning mouth protection parent fish egg passing device of factory egg -laying pool. BACKGROUND

[0002] The factory breeding is an important way of fishery production, and is divided into artificial breeding and parent fish natural spawning breeding in the factory breeding, water needs to be changed and flushed in the hatching pool of parent fish spawning during the whole spawning process of parent fish, water exchange is generated during the period, sometimes parent fish is adsorbed to the spawning mouth, not only blocks water exchange, but also causes damage to parent fish, after parent fish finishes spawning, the collection work of fertilized eggs in the spawning pool is carried out, sometimes parent fish is adsorbed to the spawning mouth, causes poor water flow, and the fertilized eggs cannot smoothly enter the egg collecting box from the spawning mouth.

[0003] In order to overcome the above-mentioned defects, a spawning mouth protection parent fish egg passing device of factory egg -laying pool is designed. CONTENT OF THE UTILITY MODEL

[0004] According to the above-mentioned technical problems, the utility model provides a spawning mouth protection parent fish egg passing device of factory egg -laying pool, which can effectively prevent parent fish from being adsorbed to the spawning mouth, and also can ensure that the fertilized eggs smoothly enter the egg collecting box from the spawning mouth.

[0005] In order to achieve the above-mentioned purposes, the technical scheme of the utility model is as follows:

[0006] A spawning mouth protection parent fish egg passing device of factory egg -laying pool, characterized by comprising a frame body, a filter cover and a bottom corner, the frame body is in a cylindrical structure, a plurality of bottom corners are fixedly welded at the bottom end of the frame body in a spaced arrangement, the filter cover is arranged on the frame body,

[0007] The frame body is welded by reinforcing steel,

[0008] The bottom corner is arranged in a circular ring structure, and the number of the bottom corner is 4.

[0009] The utility model has the advantages of:

[0010] The utility model is placed above the spawning mouth of the egg -laying pool during use, can effectively prevent parent fish from being adsorbed to the spawning mouth, and also can ensure that the fertilized eggs smoothly enter the egg collecting box from the spawning mouth.

[0011] The utility model is convenient to use, and only needs to be prevented in the spawning mouth during use, and the whole structure is simple, convenient to manufacture and good in use effect. DRAWING EXPLANATION

[0012] Figure 1The utility model discloses a whole structure schematic diagram of the oviposition mouth protection parent fish egg passing device of the factory egg production pool.

[0013] As shown in the drawing: 1. frame body, 2. filter cover, 3. bottom corner. DETAILED DESCRIPTION

[0014] The technical scheme of the utility model will be described clearly and completely in connection with the drawings, and obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor belong to the range of the utility model protection.
