Technical Field

DETAILED DESCRIPTION

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0072] like Figures 1 to 10 As shown, the fish egg hatching device of the present invention comprises a three-way pipe 1, an oxygenation pipe 2, a hatching 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] like Figures 1 to 4 As shown, the three-way pipe 1 is a T-shaped pipe, and the three-way pipe 1 has a first pipe opening 101, a second pipe opening 102 and a third pipe opening 103, and the first pipe opening 101 and the second pipe opening 102 are opposite; the oxygenation pipe 2 is connected and connected with the first pipe opening 101, and the aeration end 21 of the oxygenation pipe 2 corresponds to the third pipe opening 103; the hatching pipe 3 has two ends connected, and one end is connected and connected with the second pipe opening 102; the adjustment member 4 is arranged in the third pipe opening 103, and the adjustment member 4 is used to adjust the flux of the third pipe opening 103; the shaftless propeller 5 is arranged on the end of the hatching pipe 3 away from the three-way pipe 1;

[0074] As described above, when the incubation device is used, the oxygenation tube 2 is used to connect a pump to pump air into the water, thereby increasing the oxygen content of the water, and the fish eggs are placed in the incubation tube 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 operation of the shaftless propeller 5, the water flow will be input through the third pipe port 103, so as to realize the circulation of water through the third pipe port 103 to the hatching tube 3. At this time, the oxygen-rich water flow will flush the fish eggs, which not only ensures the oxygen content of the water body, but also simulates the real water flow environment, which is conducive to ensuring the hatching of the fish eggs.

[0077] Before use, the device controls the flux of the third nozzle 103 through the adjustment member 4 so that part of the gas can enter the incubation tube 3, thereby giving the oxygen in the air more time to dissolve in the water, thereby increasing the oxygen content of the water body, thereby achieving control of the oxygen content; at the same time, by controlling the power of the shaftless propeller 5, the degree of water flow disturbance is controlled.

[0078] In some embodiments, a large water tank can be set up, and partitions can be set inside the water tank to divide the water tank into several separate hatching pools. Then, a fish egg hatching device is set in each hatching pool, and the flux of the third pipe port 103 is adjusted by the adjustment member 4, and the power of the shaftless propeller 5 is controlled, so as to carry out hatching control, which is conducive to accumulating relevant hatching experience.

[0079] During the incubation process for different fish eggs, the oxygen content of the water flow in the incubation tube 3 can be selectively adjusted through the adjusting member 4, and the strength of the water flow can be controlled through the shaftless propeller 5, so as to adapt to the incubation of different fish eggs.

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

[0081] As in the above structure, when the flux of the third nozzle 103 is controlled by the adjusting member 4, the adjusting rod 43 is rotated to cooperate with the threaded cylinder 42 to drive the inner cylinder 44 to move up and down;

[0082] Since the end of the inner tube 44 close to the aeration end 21 is a tapered end, the inner tube 44 will divert the gas when the aeration end 21 outputs the airflow; at this time, if the inner tube 44 is completely located in the third pipe opening 103, most of the gas will be discharged through the third pipe opening 103. If the tapered end of the inner tube 44 is located at the intersection of the three pipe openings of the tee pipe 1, when the gas is diverted, part of the gas will enter the incubation tube 3 under the drive of the shaftless propeller 5 and the diversion effect of the tapered end of the inner tube 44, thereby achieving 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 in the above structure, a plurality of through holes may be provided on the surface of the inner cylinder 44 to form a filter cylinder structure. In this case, a filter material is placed in the inner cylinder 44 to filter the water body, so as to increase the cleanliness of the water body that the fish eggs contact when the water body circulates;

[0085] As in the above structure, the inner side of the center point of the conical end is connected to the adjusting rod 43, so that an annular area is formed between the inner cylinder 44 and the adjusting rod 43, which is convenient for filling and replacing the filter material.

[0086] like Figure 4 and Figure 5 As shown, the incubation tube 3 includes a top tube 31, a bottom tube 32, an end plate 33 and an interrupter plate 34, wherein the top tube 31 and the bottom tube 32 are both semicircular ring-shaped cross-section plates, and the top tube 31 and the bottom tube 32 are butted together to form a full-circular cross-section tube and clamp the second tube opening 102;

[0087] As shown in the above structure, in order to facilitate the placement of fish eggs and the removal of fry, the main body of the hatching tube 3 is composed of a top tube 31 and a bottom tube 32; when used, the fish eggs are placed on the bottom tube 32, and then the top tube 31 is placed, and then the whole is connected to the second pipe opening 102 of the three-way pipe 1;

[0088] The end plate 33 and the interrupted plate 34 are both circular plates, and are provided with hollow grooves 301. The interrupted plate 34 is also provided with a first installation 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 installation 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 three-way 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 fish eggs to avoid the aggregation of the fish eggs and the inability to fully remove the oxygen-enriched 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 the circulation of water to ensure that the fish eggs are in a moving water environment;

[0092] In order to create a more suitable hatching environment for fish eggs, the interrupter plate 34 is provided with a first installation slot 302 to selectively install a water circulation component 6, a heating component 7 or a filtering component 8; specifically, the water circulation component may also use a shaftless propeller, the heating component 7 may use an electric heating rod, and the filtering component 8 may use 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 to 6 As shown, the incubation tube 3 further includes a partition 35, which is an arc-shaped plate structure, and a plurality of partitions 35 are arranged to fit the inner wall of the bottom tube 32, and the partition 35 and the bottom tube 32 are an integrated structure; the first installation groove 302 is opened at the center of the interrupted plate 34, and a plurality of hollow grooves 301 are opened around the first installation groove 302;

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

[0099] When the first installation groove 302 is set, the first installation groove 302 is located at the center of the interrupter plate 34. Since the fish eggs contact the bottom tube 32 and usually swim at the bottom after hatching, it is possible to avoid the water circulation component 6 or the heating component 7 from damaging the fish eggs and fry.

[0100] When the water body is circulating, the water body 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 filtering component 8 will block the first installation groove 302, the water flow will only flow out through the hollow groove 301 around the heating component 7 and the filtering component 8, so the flushing of the fish eggs can be ensured;

[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, this place is close to the water circulation component 6, so the water flow is relatively strong, 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, ensures the fluidity of the water body, and can also achieve effective heating and filtering effects.

[0107] like Figures 1 to 5 As shown, at least two clamps 9 are provided, and each of the two clamps 9 clamps 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 the two ends of the connecting rod 10 are respectively connected to a clamp 9;

[0108] As 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. At the same time, the top tube 31 and the bottom tube 32 can be directly connected and fixed to the three-way pipe 1 by the clamp 9, which ensures the convenience of assembly.

[0109] In this structure, a connecting rod 10 is further provided for connecting the two clamps 9 , so that the consistency of the two clamps 9 can be ensured, thereby achieving effective fixation of the incubation tube 3 .

[0110] like Figure 5 As shown, 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 respectively abut against a clamping ring 91; the two ends of the top rod 1011 are connected to the clamping ring 91 abutting against the top tube 31, and the top rod 1011 is provided with a plurality of second assembly grooves 1001, and the second assembly grooves 1001 are used to install the heating component 7 or the filtering component 8; the two ends of the bottom rod 1012 are connected to the clamping ring 91 abutting against the bottom tube 32;

[0111] As in the above structure, the two clamps 9 have four clamp rings 91, which are used to fit the top tube 31 and the bottom tube 32 of the incubation tube 3, and then the clamp rings 91 are locked and fixed by fasteners such as bolts;

[0112] The connecting rod 10 is divided into a top rod 1011 and a bottom rod 1012. The top rod 1011 is provided with a second assembly groove 1001 for installing the heating component 7 or the filtering component 8. Therefore, the heating component 7 and the filtering component 8 can be selectively installed on the top rod 1011 or the interrupter plate 34. Here, a groove corresponding to the second assembly groove 1001 needs to be opened on the top tube 31 so that the heating component 7 or the filtering component 8 can extend into the incubation tube 3.

[0113] Furthermore, the bottom rod 1012 is provided with a wiring 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 wiring groove 1002; the bottom tube 32 and the three-way tube 1 are set as an integrated structure;

[0114] As in the above structure, by providing a wiring groove 1002 on the bottom rod 1012, it is convenient to lay the wiring harness, so as to supply power to the water circulation component 6 or the heating component 7 installed on the interrupter plate 34;

[0115] In specific application, the water circulation component 6 and the heating component 7 are first arranged on the interrupter plate 34, and a hole is opened on the bottom tube 32 to form a wire outlet hole to lead out the wire harness. In this way, when the clamp 9 and the connecting rod 10 are installed, the wire harness for the water circulation component 6 and the heating component 7 can be arranged in the wiring groove 1002 of the bottom rod 1012, thereby improving the convenience of integration;

[0116] When laying out the wiring harness, seal the outlet holes with glue plugs or hot melt adhesive;

[0117] Furthermore, the bottom pipe 32 can be configured as an integral structure with the tee pipe 1. When assembling, it is only necessary to connect the top pipe 31 to the bottom pipe 32 and then install the clamp 9 to fix it, which further improves the convenience of grouping.
