Technical Field
[0001] This utility model belongs to the technical field of fish egg incubation devices, specifically relating to a fish egg incubation device that is easy to control. Background Technology
[0002] Fish egg hatching is the process of cultivating fish eggs into fry, a crucial step in aquaculture and ecological conservation. Its success is influenced by many factors, including water temperature, water quality, fish species characteristics, and technical operations. In fish egg hatching experiments, small-scale hatching devices are typically used to assist in the experiments.
[0003] Existing experimental fish egg incubation devices have poor control over the uniformity of water temperature and oxygen in the incubation water, which can create regional differences in the incubation water and affect the efficiency of fish egg incubation. Moreover, most existing fish egg incubation devices place the fish eggs statically in the incubation device, which makes it impossible to remove fish eggs that cannot hatch normally during the incubation process in a timely manner, thus affecting the incubation of normal fish eggs.
[0004] Based on this, a fish egg incubation device that is easy to control is proposed. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-3 As shown, this utility model provides a technical solution: a fish egg incubation device that is easy to control, including an incubation box 1, a rotating frame 2 and a fish egg control mechanism 3;
[0026] The incubation box 1 is a rectangular box with an opening 12 at the top. A cover plate is snapped into the opening 12. The cover plate is a transparent plate and can be used to provide supplemental lighting to the incubation box 1.
[0027] The bottom of the incubation box 1 is fixed with a bracket 11, which provides stable support when the incubation box 1 is placed.
[0028] Furthermore, an impurity filter chamber 13 is provided in the middle of the bottom end of the incubation box 1, and a control valve plate is also provided on the top of the impurity filter chamber 13 inside the incubation box 1. When the control valve plate is closed, the impurities in the impurity filter chamber 13 can be cleaned.
[0029] The impurity filter chamber 13 is fitted with a U-shaped filter plate 14. During use, solid impurities generated in the hatching water in the hatching box 1 settle naturally and can be collected in the U-shaped filter plate 14. During use, the impurities in the U-shaped filter plate 14 are cleaned regularly to improve the hatching efficiency of fish eggs in the hatching box 1.
[0030] A circulation pump 15 is fixedly connected to the outside of the impurity filter chamber 13. An oxygenation chamber 16 is fixed to the top of the incubation chamber 1. An oxygen pipeline and a circulating water pipeline are provided on the oxygenation chamber 16. The oxygen pipeline is connected to an external oxygen device through a flexible hose to add dissolved oxygen to the incubation chamber 1. The circulating water pipeline is connected to the outlet of the circulation pump 15 through a water pipe. The bottom of the oxygenation chamber 16 is provided with multiple connecting holes that communicate with the inner cavity of the incubation chamber 1 to facilitate water circulation. The circulating water pipeline is located on the outside of the incubation chamber 1. During use, when the water temperature inside the incubation chamber 1 exceeds the preset maximum temperature value, external water circulation can be used to cool the water inside the incubation chamber 1.
[0031] The incubation chamber 1 is also equipped with multiple monitoring probes 17, which consist of temperature probes and oxygen probes. The monitoring probes 17 are used to monitor the temperature and oxygen content of the water in the incubation chamber 1.
[0032] At least two electric heating rods 18 are installed inside the incubation box 1. The electric heating rods 18 are powered by an external power source and are used to heat the water inside the incubation box 1.
[0033] The incubation box 1 is rotatably connected to a rotating frame 2 in the middle. The rotating frame 2 includes a circular frame 21, a central shaft 22, and horizontal rods 23. There are two circular frames 21, which are fixed at both ends of the central shaft 22. Six horizontal rods 23 are fixed at equal intervals between the two circular frames 21. The central shaft 22 is driven to rotate by a stepper motor on the outside of the incubation box 1. The stepper motor is a low-speed motor with a rotation speed of 1-2 rpm during use. When the central shaft 22 is driven to rotate by the stepper motor, it can synchronously drive the six horizontal rods 23 to rotate. At the same time, the low-speed rotation can avoid damage to the fish eggs.
[0034] The transverse rod 23 is parallel to the intermediate shaft 22, which facilitates the connection between the fish egg control mechanism 3 and the rotating frame 2 through the transverse rod 23.
[0035] The fish egg control mechanism 3 is provided in six parts. The fish egg control mechanism 3 includes an inverted U-shaped net frame 31, a side plate 32, a counterweight groove 33, and a middle cylinder 34. The side plates 32 are fixed at the openings on both sides of the inverted U-shaped net frame 31. The side plates 32 are light-transmitting plates. The middle cylinder 34 is fixed between the centers of two side plates 32. The two ends of the middle cylinder 34 pass through the side plates 32 respectively. The six middle cylinders 34 are rotatably connected to the outside of the corresponding horizontal rods 23. The fish egg control mechanism 3 and the rotating frame 2 are connected through the middle cylinders 34.
[0036] One side of the inverted U-shaped net frame 31 is also movably connected to an opening and closing net plate 35. The opening and closing net plate 35 can be used to put the fish eggs to be hatched into the fish egg control mechanism 3, and the opening and closing net plate 35 can also be used to take out the hatched fish fry from the fish egg control mechanism 3.
[0037] The mesh size of the inverted U-shaped mesh frame 31 is smaller than the minimum outer diameter of the fish eggs, which prevents the fish eggs from sliding out of the fish egg control mechanism 3 through the inverted U-shaped mesh frame 31 during the early stage of incubation.
[0038] The counterweight groove 33 is fixed to the bottom of the inverted U-shaped mesh frame 31 and the side plate 32. The counterweight groove 33, the inverted U-shaped mesh frame 31 and the side plate 32 cooperate to form a closed fish egg incubation space. The fish egg incubation space is used to complete the incubation of fish eggs. The inner wall of the fish egg incubation space is smooth, which can avoid damage to the fish eggs during use and facilitate the completion of the incubation of fish eggs.
[0039] The height and width of the inner cavity of the incubation box 1 are not less than the sum of the outer diameter of the circular frame 21 and the maximum length of the fish egg adjustment mechanism 3, so as to avoid the outer side of the fish egg adjustment mechanism 3 from contacting the inner cavity of the incubation box 1 during the rotation of the rotating frame 2, and facilitate the free adjustment of the fish egg adjustment mechanism 3 within the rotating frame 2.
[0040] The top center of the counterweight groove 33 is provided with a semi-circular cavity protrusion, which can increase the volume of the counterweight cavity inside the counterweight groove 33, so that the fish egg adjustment mechanism 3 always keeps the bottom facing down during rotation. It can also form a bulge in the middle of the inner cavity of the fish egg adjustment mechanism 3, dividing the inner bottom cavity of the fish egg adjustment mechanism 3 into two areas, avoiding the phenomenon of fish eggs accumulating in one area during the adjustment of the position of the fish egg adjustment mechanism 3.
[0041] In summary, when using the hatching tank 1, the hatching water is injected into the hatching tank 1. The oxygen concentration of the hatching water is adjusted by the circulation pump 15 and the oxygenation chamber 16. The temperature of the hatching water is controlled by the electric heating rod 18. The temperature and oxygen concentration of the water are monitored by the monitoring probe 17. After the temperature and oxygen concentration reach the preset values, the fish eggs to be hatched are placed into the fish egg adjustment mechanism 3.
[0042] After the fish eggs are placed in the egg adjustment mechanism 3, the cover is closed. If supplemental lighting is needed, an external light source is used. Simultaneously, the stepper motor is activated to rotate the intermediate shaft 22 of the rotating frame 2, thereby synchronously adjusting the longitudinal and lateral positions of the six egg adjustment mechanisms 3 within the incubation box 1. The specific positions of the egg adjustment mechanisms 3 during the rotation of the rotating frame 2 are as follows: Figure 1 As shown, the rotating frame 2 can make the water parameters in the incubation box 1 uniform when it rotates, which can facilitate the control of the fish egg incubation process and is convenient and practical.
