[0071] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0072] like Figures 1-10 As shown, the fish egg hatching device of the present invention includes a three-way pipe 1, an oxygenation pipe 2, an incubation pipe 3, an adjustment member 4, a shaftless propeller 5, a water circulation component 6, a heating component 7, a filtering component 8, a clamp 9 and a connecting rod.

[0073] likeFigures 1-4 As shown, the tee pipe 1 is a T-shaped pipe, the tee pipe 1 has a first pipe opening 101, a second pipe opening 102 and a third pipe opening 103, the first pipe opening 101 and the second pipe opening 102 are opposite; the oxygenation pipe 2 is connected through the first pipe opening 101, and the aeration end 21 of the oxygenation pipe 2 corresponds to the third pipe opening 103; the incubation pipe 3 is through at both ends, and one end is connected through the second pipe opening 102; the adjusting piece 4 is arranged in the third pipe opening 103, and the adjusting piece 4 is used for adjusting the flux of the third pipe opening 103; the shaftless propeller 5 is arranged on the end of the incubation pipe 3 away from the tee pipe 1;

[0074] As the above structure, when the present incubation device is applied, the oxygenation pipe 2 is used for connecting a pump to pump air into water, so as to increase the oxygen content of the water body, and the fish eggs are placed in the incubation pipe 3;

[0075] Specifically, since the aeration end 21 of the oxygenation pipe 2 is located in the tee pipe 1 and corresponds to the third pipe opening 103, when aeration is performed, the airflow surges upward and is discharged through the third pipe opening 103;

[0076] At the same time, under the work of the shaftless propeller 5, the water flow is input through the third pipe opening 103, so as to realize the circulation of the water flow through the third pipe opening 103 to the incubation pipe 3, at this time, the water flow rich in oxygen will flush the fish eggs, not only ensuring the oxygen content of the water body, but also simulating the real water flow environment, which is beneficial to ensure the incubation of the fish eggs;

[0077] Before application, the present device controls the flux of the third pipe opening 103 through the adjusting piece 4, so that part of the gas can enter the incubation pipe 3, so as to make the oxygen in the air have more time to dissolve in the water, thereby increasing the oxygen content of the water body, so as to realize the control of the oxygen content; at the same time, the power of the shaftless propeller 5 is controlled, so as to realize the control of the disturbance degree of the water flow.

[0078] In some embodiments, a large water tank can be provided, and a partition is arranged in the water tank to divide the water tank into a plurality of separate incubation pools, then an egg incubation device is arranged in each incubation pool, and the flux of the third pipe opening 103 is adjusted through the adjusting piece 4, and the power of the shaftless propeller 5 is controlled, so as to carry out incubation control, which is beneficial to accumulate relevant incubation experience.

[0079] In the incubation process of different fish eggs, the oxygen content of the water flow in the incubation pipe 3 can be adjusted by the adjusting piece 4, and the water flow strength can be controlled by the shaftless propeller 5, so as to adapt to the incubation of different fish eggs.

[0080] As Figure 4 and Figure 7As shown, the adjusting member 4 comprises an end cover 41, a threaded cylinder 42, an adjusting rod 43 and an inner cylinder 44, wherein the end cover 41 is buckled on the third pipe opening 103; the threaded cylinder 42 is coaxially arranged with the third pipe opening 103, the threaded cylinder 42 is connected with the end cover 41 and forms a through hole 401; the adjusting rod 43 is connected with the threaded cylinder 42 through threads, and one end of the adjusting rod 43 extends into the third pipe opening 103; the inner cylinder 44 is arranged in the third pipe opening 103, and one end of the inner cylinder 44 close to the aeration end 21 is a tapered end, and the inner side of the center point of the tapered end is connected with the adjusting rod 43;

[0081] As shown above, when the flux of the third pipe opening 103 is controlled by the adjusting member 4, the adjusting rod 43 is rotated, and the threaded cylinder 42 is matched, so that the inner cylinder 44 is driven to displace up and down;

[0082] Since one end of the inner cylinder 44 close to the aeration end 21 is a tapered end, when the airflow is output at the aeration end 21, the inner cylinder 44 will split the airflow; at this time, if the inner cylinder 44 is completely located in the third pipe opening 103, most of the airflow will be discharged through the third pipe opening 103, if the tapered end of the inner cylinder 44 is located at the intersection of the three pipe openings of the three-way pipe 1, under the driving of the shaftless propeller 5 and the splitting effect of the tapered end of the inner cylinder 44, part of the airflow will enter the hatching pipe 3, so as to realize the control of the oxygen content of the water body.

[0083] Specifically, the inner cylinder 44 is a sieve cylinder, and the inner cylinder 44 is filled with filter material;

[0084] As shown above, the surface of the inner cylinder 44 can be provided with a plurality of through holes to form a filter cylinder structure, at this time, the filter material is put into the inner cylinder 44, so as to filter the water body, so as to increase the cleanliness of the water body contacted by the fish eggs when the water body flows;

[0085] As shown above, the inner side of the center point of the tapered end is connected with the adjusting rod 43, so that an annular area is formed between the inner cylinder 44 and the adjusting rod 43, which facilitates filling and replacing the filter material.

[0086] As shown above, the inner side of the center point of the tapered end is connected with the adjusting rod 43, so that an annular area is formed between the inner cylinder 44 and the adjusting rod 43, which facilitates filling and replacing the filter material. Figure 4 and Figure 5 As shown, the hatching pipe 3 comprises a top pipe 31, a bottom pipe 32, an end plate 33 and an intermittent plate 34, wherein the top pipe 31 and the bottom pipe 32 are both semi-circular ring section plates, the top pipe 31 and the bottom pipe 32 are butt jointed to form a whole circular section pipe and clamped on the second pipe opening 102;

[0087] As shown above, in order to facilitate placing fish eggs and taking out fry, the main body of the hatching pipe 3 is composed of two parts of the top pipe 31 and the bottom pipe 32; in application, the fish eggs are placed on the bottom pipe 32, then the top pipe 31 is placed, and then the whole is butt jointed to the second pipe opening 102 of the three-way pipe 1;

[0088] The end plates 33 and the interrupted plates 34 are both circular plates, and are provided with hollow grooves 301. The interrupted plate 34 is also provided with a first mounting groove 302. One end plate 33 is provided at each end of the bottom tube 32. Multiple interrupted plates 34 are provided between the two end plates 33. The first mounting groove 302 is used to install the water circulation component 6, the heating component 7 or the filtering component 8.

[0089] As in the above structure, the two end plates 33 are used to seal the ends of the hatching tube 3 to prevent the hatched seedlings from entering the tee pipe 1 or swimming out through the shaftless propeller 5;

[0090] The interrupter plate 34 is used to divide the interior of the hatching tube 3 into a plurality of hatching chambers for spacing the eggs to prevent the eggs from agglomerating and being unable to fully contact the oxygen-rich water flow, thereby ensuring the hatching process.

[0091] The hollow grooves 301 on the end plate 33 and the interrupted plate 34 are used for water circulation to ensure that the fish eggs are in a dynamic water environment;

[0092] In order to create a more suitable incubation environment for fish eggs, the interrupter plate 34 defines a first mounting slot 302 for selectively mounting a water circulation assembly 6, a heating assembly 7, or a filter assembly 8. Specifically, the water circulation assembly may also employ a shaftless propeller, the heating assembly 7 may employ an electric heating rod, and the filter assembly 8 may employ a water filter element.

[0093] The figure only shows the installation structure of the water circulation component 6 and the heating component 7 on the interrupter plate 34. In specific applications, if filtering is required, the filter component 8 can be snapped into the first installation groove 302;

[0094] Specifically, the end plate 33 and the interrupter plate 34 are configured as an integral structure with the top tube 31 or the bottom tube 32;

[0095] As in the above structure, by integrating the end plate 33 and the interrupter plate 34 with the top tube 31 or the bottom tube 32, the convenience during assembly can be improved. During assembly, the top tube 31 and the bottom tube 32 can be directly docked. After docking, the rear end plate 33 and the interrupter plate 34 will interrupt the inner cavity of the incubation tube 3.

[0096] In some embodiments, the fish eggs can be placed in a hollow container first and then placed in the hatching tube 3, so as to prevent the hatched fry from being damaged by the rotation of the shaftless propeller or the heating rod.

[0097] like Figures 4-6 As shown, the incubation tube 3 further includes a partition 35, which is an arc-shaped plate structure. A plurality of partitions 35 are provided to fit the inner wall of the bottom tube 32, and the partitions 35 and the bottom tube 32 are an integral structure. A first mounting groove 302 is provided in the center of the interrupted plate 34, and a plurality of hollow grooves 301 are provided around the first mounting groove 302.

[0098] As in the above structure, by providing the partition 35, the eggs can be further separated in the hatching chamber separated by the interrupted plate 34, and the adhesion of the eggs can be improved to avoid the problem of the eggs flowing;

[0099] When the first mounting groove 302 is provided, the first mounting groove 302 is located at the center of the interrupted plate 34. Since the fish eggs contact the bottom tube 32 and usually swim at the bottom after hatching, the water circulation component 6 or the heating component 7 can be prevented from damaging the fish eggs and fry as much as possible.

[0100] When the water body circulates, it circulates through the hollow grooves 301 located at the edges of the interrupted plate 34, so that the water flow can disturb the fish eggs as much as possible to ensure the hatching efficiency.

[0101] When some fish eggs are about to hatch, the water circulation component 6 is turned off and only the shaftless propeller 5 is turned on to avoid damage to the fry.

[0102] like Figure 4 As shown, any interrupter plate 34 is installed with a water circulation component 6, and the interrupter plates 34 on both sides are installed with a heating component 7 or a filtering component 8;

[0103] As in the above structure, when arranging the water circulation component 6, the heating component 7 or the filtering component 8, they should be arranged at intervals;

[0104] Among them, since the heating component 7 or the filter component 8 blocks the first installation groove 302, the water flow only flows out through the hollow groove 301 around the heating component 7 and the filter component 8, thereby ensuring the flushing of the fish eggs;

[0105] The water circulation component 6 adopts a shaftless propeller, so the water will flow out through the shaftless propeller. Although the flow cross-section is large, the water flow is relatively strong here because it is close to the water circulation component 6, which can also ensure the flushing of fish eggs.

[0106] This structure effectively utilizes the structural layout of the water circulation component 6, the heating component 7 and the filtering component 8, ensuring the fluidity of the water body and achieving effective heating and filtering effects.

[0107] like Figures 1-5 As shown, at least two clamps 9 are provided, each clamping one end of the hatching tube 3 to relatively fix the second pipe opening 102, the top tube 31 and the bottom tube 32; the connecting rod 10 abuts against the hatching tube 3, and each end of the connecting rod 10 is connected to a clamp 9;

[0108] As shown in the above structure, when fixing the top tube 31 and the bottom tube 32 of the incubation tube 3, the clamp 9 can be used to fix them together. At the same time, the clamp 9 can be used to directly connect and fix the top tube 31 and the bottom tube 32 to the tee pipe 1, ensuring the convenience of assembly.

[0109] In the structure, the connecting rod 10 is arranged to connect the two clamps 9, so as to ensure the consistency of the two clamps 9, thereby achieving effective fixation of the incubation tube 3.

[0110] As shown in Figure 5 the clamp 9 includes two clamping rings 91, and the connecting rod 10 includes a top rod 1011 and a bottom rod 1012, wherein the two ends of the top tube 31 and the bottom tube 32 are respectively held by one clamping ring 91; the two ends of the top rod 1011 are connected with the clamping ring 91 holding the top tube 31, and the top rod 1011 is provided with a plurality of second assembly grooves 1001 for mounting the heating assembly 7 or the filtering assembly 8; the two ends of the bottom rod 1012 are connected with the clamping ring 91 holding the bottom tube 32;

[0111] According to the above structure, the two clamps 9 have four clamping rings 91, which are used to fit the top tube 31 and the bottom tube 32 of the incubation tube 3, and then the clamping rings 91 are locked and fixed by bolts or other fasteners;

[0112] The connecting rod 10 is divided into the top rod 1011 and the bottom rod 1012, the top rod 1011 is provided with the second assembly groove 1001 for mounting the heating assembly 7 or the filtering assembly 8, so that the heating assembly 7 and the filtering assembly 8 can be selectively mounted on the top rod 1011 or the intermittent plate 34, and the top tube 31 needs to be slotted corresponding to the second assembly groove 1001, so that the heating assembly 7 or the filtering assembly 8 can extend into the incubation tube 3.

[0113] Further, the bottom rod 1012 is provided with a wire groove 1002 along the axial direction of the incubation tube 3, and the bottom tube 32 is provided with a wire outlet hole corresponding to the wire groove 1002; the bottom tube 32 is arranged in an integrated structure with the tee pipe 1;

[0114] According to the above structure, the wire groove 1002 is arranged on the bottom rod 1012, which facilitates the layout of the wire harness, thereby providing power supply for the water flow circulating assembly 6 or the heating assembly 7 mounted on the intermittent plate 34;

[0115] In specific application, the water flow circulating assembly 6 and the heating assembly 7 are laid out on the intermittent plate 34, and the wire outlet hole is formed on the bottom tube 32 to lead out the wire harness, so that when the clamp 9 and the connecting rod 10 are installed, the wire harness for the water flow circulating assembly 6 and the heating assembly 7 can be laid in the wire groove 1002 of the bottom rod 1012, thereby improving the convenience of integration;
