Description

Technical Field

[0001] The utility model relates to the technical field of fish seedling breeding, in particular to fish egg hatching equipment and a hatching frame. Background Art

[0002] In recent years, with the in-depth research and technological progress of the aquaculture industry, the full artificial reproduction of sturgeons has been achieved. Despite these advances, the sturgeon breeding process still faces some technical challenges, especially in the hatching stage of fertilized eggs.

[0003] The hatching process of sturgeon eggs has strict requirements on environmental conditions, such as sufficient dissolved oxygen and suitable flowing water. These conditions are intended to simulate the growth environment of eggs in nature to promote the normal development and hatching of eggs.

[0004] Although each female sturgeon carries a large number of eggs and the fertilization rate can reach 99%, the current hatching rate is not ideal due to the limitations of hatching technology, which restricts the development of sturgeon farming and the increase in production. At present, most sturgeon breeders still rely on traditional incubators. The design of traditional incubators fails to effectively prevent the accumulation of fertilized eggs, resulting in fertilized eggs lacking oxygen or even death. Dead fertilized eggs will mold and stick to good eggs, further reducing the hatching rate. Utility Model Content

[0005] Aiming at the technical problem that traditional incubators fail to effectively prevent the accumulation of fertilized eggs, the utility model provides a fish egg incubation device and an incubation frame, which have the advantage of preventing the accumulation of fertilized eggs.

[0027] Four support tubes are respectively arranged at the four corners of the rectangular frame, and the two ends of the support tubes are respectively connected to the corners of the two rectangular frames. The four support tubes and the two rectangular frames constitute a support skeleton;

[0028] The mesh is laid inside the support frame and connected to all PVC pipes and all support pipes to form a structure with an open top.

[0041] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0042] See also Figure 1-Figure 3 , a fish egg hatching device, comprising a basin body 1, a hatching frame 2, a water pipe and a drain pipe 3. Specifically, the basin body 1 is a circular structure, the top of the basin body 1 is an open structure, the bottom of the basin body 1 has a drain hole, and there is clean water in the basin body 1, and the liquid level of the clean water is located below the mouth of the basin body 1.

[0043] There are multiple hatching frames 2 in the basin body 1, and all the hatching frames 2 float on the surface of the clean water.

[0044] One end of the water pipe is connected to the clean water supply (usually a faucet), and the other end is inside the basin body 1 and extends from the middle of the basin body 1 to the edge of the basin body 1. This end of the water pipe is a horizontal structure and is submerged below the surface of the clean water.

[0045] A plurality of flushing holes 4 are arranged on the water pipe, and all flushing holes 4 are located at one end of the water pipe which is horizontally placed in the basin body 1, and all flushing holes 4 are oriented in the same direction. There is an angle between the direction of the water flow output through the flushing hole 4 and the liquid level of the clean water which is less than 90° and greater than 0°.

[0046] One end of the drain pipe 3 is arranged on the drain hole, and the drain pipe 3 is arranged in the vertical direction. At the same time, the top end of the drain pipe 3 is open and is located below the mouth of the basin body 1. Since the drain pipe 3 is connected to the drain hole, when the liquid level of the clean water is higher than the height of the drain pipe 3, the clean water will be discharged from the drain pipe 3, so that the height of the drain pipe 3 is the same as the depth of the clean water.

[0047] In this embodiment, the basin body 1 is filled with clean water, the hatching frame 2 is floated on the surface of the clean water, and the fertilized eggs are placed in the hatching frame 2 to provide necessary conditions for the hatching of the fertilized eggs.

[0048] Then, fresh clean water is fed into the basin body 1 by using a water pipe, and the angle between the flushing hole 4 on the water pipe and the clean water level is maintained less than 90 degrees.

[0049] During this process, the water flow output from the flushing hole 4 exerts a certain impact force on the hatching frame 2 and the clean water in the basin body 1 , causing the clean water and the hatching frame 2 to rotate in the basin body 1 .

[0050] When the hatching frame 2 passes over the flushing hole 4, the water flow output from the flushing hole 4 is filled into the hatching frame 2 from the bottom of the hatching frame 2, and the fertilized eggs in the hatching frame 2 are dispersed. Since all the hatching frames 2 rotate in the basin body 1, all the fertilized eggs in each hatching frame 2 can be dispersed by the clean water from the bottom of the hatching frame 2 within a certain period of time.

[0051] In one specific embodiment:

[0052] The water pipe includes a water inlet pipe 5, a flushing pipe 6 and a flushing pipe 7. One end of the water inlet pipe 5 is connected to the clean water supply, and the other end of the water inlet pipe 5 is an L-shaped structure, extending from the top of the basin body 1 to the middle of the basin body 1 and then inserted under the liquid surface of the clean water.

[0053] One end of the flushing pipe 6 and one end of the water flushing pipe 7 are both connected to one end of the water inlet pipe 5 located in the clean water surface, and the other end of the flushing pipe 6 and the other end of the water flushing pipe 7 are both closed structures. The flushing pipe 6 and the water flushing pipe 7 are both arranged in the horizontal direction in the basin body 1.

[0054] A plurality of flushing holes 4 are provided on the flushing pipe 6, and a plurality of flushing holes 8 are provided on the flushing pipe 7, wherein the direction of water flow outputted from the flushing holes 8 is parallel to the clean water surface.

[0055] In the present technical solution, the angle between the flushing hole 4 and the clean water surface is between 80° and 90°. At the same time, the water flow output from the flushing hole 8 and the water flow output from the flushing hole 4 both have the function of driving the clean water in the basin body 1 to rotate, and the directions in which the clean water in the basin body 1 is driven by the two are also the same.

[0056] In this embodiment, the end of the water pipe located in the basin body 1 is divided into a flushing pipe 6 and a flushing pipe 7, and the flushing hole 4 and the flushing hole 8 meet specific conditions, so that the main function of the flushing pipe 6 and the flushing hole 4 is to drive the rotation of the clean water body, and drive all the hatching frames 2 to rotate on the clean water surface through the rotation of the clean water body; the main function of the flushing pipe 7 and the flushing hole 8 is to disperse the fertilized eggs in the hatching frame 2.

[0057] The functions of the flushing pipe 6 and the water flushing pipe 7 are differentiated to reduce the probability of fertilized egg accumulation.

[0058] In another specific embodiment:

[0059] The flushing pipe 6 and the water pipe 7 are both L-shaped, one end of the flushing pipe 6 and the other end of the water pipe 7 are closed structures and abut against the bottom surface of the basin body 1, the other end of the flushing pipe 6 and the other end of the water pipe 7 are connected to the water inlet pipe 5 and are both arranged in the horizontal direction.

[0060] The flushing holes 4 are located at one end of the flushing pipe 6 in the horizontal direction, and all the flushing holes 4 are distributed in a straight line. The flushing holes 8 are located at one end of the flushing pipe 7 in the horizontal direction, and all the flushing holes 8 are distributed in a straight line.

[0061] By arranging both the flushing pipe 6 and the water flushing pipe 7 into an L-shaped structure, the two can be supported on the bottom surface of the basin body 1, so that the flushing pipe 6 and the water flushing pipe 7 remain stable.

[0062] In another specific embodiment:

[0063] The number of the hatching frames 2 is an even number, and every two hatching frames 2 are connected as a whole and float on the surface of the clean water. By connecting the two hatching frames 2 as a whole, it is helpful for the flushing pipe 6 to drive the hatching frames 2 to rotate on the surface of the clean water. Example

[0064] See also Figure 1 and Figure 2 A hatching frame 2 includes a PVC tube 21, a support tube 22, a mesh 23 and a foam board 24. There are eight PVC tubes 21, and every four PVC tubes 21 are connected end to end to form a rectangular frame. The rectangular frame is square, and eight PVC tubes 21 are used to form two rectangular frames.

[0065] There are four support tubes 22 , which are respectively vertically arranged between the two rectangular frames, and the two ends of the support tubes 22 are respectively connected to the corners of the two rectangular frames. The two rectangular frames and the four support tubes 22 form a three-dimensional support skeleton.

[0066] The mesh cloth 23 is laid inside the support frame, and the mesh cloth 23 is fixedly connected to the support tube 22 and the PVC tube 21, so that the bottom surface and four side surfaces of the entire support frame are covered, and the top surface of the support frame is in an open structure.

[0067] In this embodiment, since the PVC tube 21 and the support tube 22 are both hollow structures, the support frame formed by the PVC tube 21 and the support tube 22 can float on the surface of the clean water. By arranging the mesh 23 on the support frame, the fertilized egg can be placed in the mesh 23, and the mesh 23 has good water permeability.

[0068] Preferably, a foam plate 24 is provided on two opposite sides of the support frame, respectively, and the buoyancy of the entire hatching frame 2 in clean water is improved by providing the foam plates 24.

[0069] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
