[0002] After fish egg fertilization, immediately carry out embryo development process, this process includes cell division, organ formation etc. stage. Under the condition of suitable water temperature, dissolved oxygen etc., embryo gradually develops into fish fry with complete form. Dissolved oxygen plays an important role in the hatching process of fish egg. If the dissolved oxygen content in water is insufficient, will seriously hinder the normal development process of embryo, in extreme case can even lead to fish egg asphyxia and death due to lack of oxygen. In view of this, in the actual cultivation process, generally need to help oxygenation hatching device to ensure that fish egg obtains necessary oxygen supply. The traditional fish egg oxygenation hatching device mainly consists of the following several parts. The hatching container is usually transparent material, such as glass jar or plastic box, to facilitate the observation of fish egg hatching condition. The oxygenation equipment generally includes air pump and aeration stone, the air pump transports air to the aeration stone, and the aeration stone releases micro-bubbles in water to increase the dissolved oxygen of fish egg. The filter system is composed of filter cotton etc., is used to remove impurities and waste in water, maintains water quality clean. In addition, it is also equipped with heating device, such as heating rod, to maintain suitable water temperature, promote fish egg hatching. The overall structure is relatively simple, but plays an important role in the process of fish egg hatching.
[0003] The aeration structure of the traditional device is relatively simple, generally only through the air pump to connect the aeration stone to inject gas directly into the water. However, when the aeration intensity is too large, strong water flow impact force and bubble burst force will be generated. Due to the fragility of fish egg, this powerful external force action is easy to cause fish egg to be scattered by water flow, appear stacking, impact container wall or other medium, and then cause the damage of fish egg structure even complete rupture. In addition, the violent bubble burst will produce local high pressure area, and the embryo development process in fish egg is disturbed. This damage will significantly reduce the hatching rate of fish egg, even if part of fish egg can hatch, the hatched fish fry often accompanies the problems such as poor development, affects its subsequent growth and survival. UTILITY MODEL CONTENTS
[0004] In order to make up for the above shortcomings, the utility model provides a fish egg oxygenation hatching device, aims at improving the problem that the violent bubble burst of the aeration structure of the traditional device produces local high pressure area, this damage greatly reduces the hatching rate of fish egg.

[0022] 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.
[0023] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a fish egg oxygenation and incubation device, comprising a fixed frame 1, which supports and fixes other components, providing a stable structural foundation for the entire device. A culture glass 2 is fixedly connected inside the fixed frame 1. The culture glass 2 is used to hold fish eggs and water required for incubation, providing space for the fish eggs to incubate. The transparent material facilitates observation of the incubation of the fish eggs. An oxygen pump 3 is installed on the top of the culture glass 2, which provides a sufficient oxygen supply. An oxygenation component is installed inside the culture glass 2 for supplying oxygen to the fish eggs. A drug injection component is installed inside the fixed frame 1 for delivering drugs.
[0024] The oxygenation component includes aeration stones 6, which release oxygen into the water in the form of small bubbles through their internal pores, increasing the dissolved oxygen content in the water. Multiple aeration stones 6 are placed inside the culture glass 2. Each aeration stone 6 has a connector 5 fixedly connected to its top, which serves as a transition and connection. An air supply pipe 4 is fixedly connected inside the connector 5, which is a conduit for delivering oxygen to the connector 5 and the aeration stone 6. The other end of the air supply pipe 4 is fixedly connected to the output end of the oxygen pump 3. Each aeration stone 6 has a suction cup 8 fixedly connected to its bottom, which is used to fix the aeration stone 6 inside the culture glass 2, ensuring that the aeration stone 6 is stable in position during operation. The suction cup 8 is adsorbed inside the culture glass 2. Each aeration stone 6 has a sponge ring 7 on its outer wall, which makes the oxygen more evenly distributed in the incubation water.
[0025] Specifically, firstly, when oxygenation is needed for the fish eggs inside the culture glass 2, the oxygen pump 3 can be activated. The oxygen pump 3 outputs oxygen to the air supply pipe 4, delivering the oxygen into the air supply pipe 4. Then, through the connection between the air supply pipe 4 and the connector 5, the oxygen enters the connector 5 and also enters the aeration stone 6. This increases the dissolved oxygen content in the water, providing sufficient oxygen for the hatching of the fish eggs. The aeration stone 6 is attached to the inside of the culture glass 2 by the suction cup 8, thus maintaining stability. The position of the aeration stone 6 determines that the aeration method is to inject oxygen directly into the middle layer of the culture glass 2, rather than directly aerating the fish eggs through the traditional aeration holes. This method allows the oxygen bubbles to enter the inside of the culture glass 2 in a relatively gentle manner, avoiding significant damage to the fish eggs to a certain extent and reducing the breakage rate of the fish eggs. At the same time, through the sponge ring 7 on the outer layer of the aeration stone 6, due to its pores, the airflow generated by the aeration device can be adjusted to a certain extent, which can make the oxygen more evenly distributed in the hatching water and improve the oxygen utilization efficiency.
[0026] Reference Figure 3The injection assembly includes a platform 9, which supports other components. The platform 9 is fixedly connected inside the mounting frame 1. A side platform 10 is fixedly connected to the side wall of the platform 9. A groove 11 is provided inside the platform 9 to provide a sliding track for the pusher 13, ensuring stable horizontal movement of the pusher 13. An electric push rod 12 is fixedly connected to the side wall of the platform 9. The output end of the electric push rod 12 is fixedly connected to the pusher 13, which drives the movement of components such as the connecting platform 16. The pusher 13 is slidably connected inside the groove 11, and a drug tube 14 is fixedly connected inside the pusher 13. The medicine tube 14 is a container for storing the medicine solution and providing the medicine source for the injection process. The medicine tube 14 is rotatably connected to a rotating column 15. The top of the rotating column 15 is fixedly connected to a connecting platform 16. The top of the connecting platform 16 is rotatably connected to a pulley 17. The pulley 17 assists the connecting platform 16 in moving and changing its angle. The bottom of the rotating column 15 is fixedly connected to a connecting shaft 18. The bottom of the connecting shaft 18 is fixedly connected to a connector 19. Both sides of the connector 19 are fixedly connected to droppers 20. The droppers 20 evenly spray the medicine solution into the culture glass 2 to realize the injection operation of fish eggs.
[0027] Specifically, when it is necessary to inject medicine into the fish eggs inside the culture glass 2, the electric push rod 12 can be activated. The electric push rod 12 will output power to the push platform 13, pushing the push platform 13 to slide horizontally inside the slide 11. The displacement of the push platform 13 will cause the top connecting platform 16 to move synchronously. When the connecting platform 16 touches the side platform 10, it will be pushed by the side platform 10. At this time, the pulley 17 slides on the side wall of the side platform 10, and the connecting platform 16 will change its own angle, causing the rotating column 15 at its bottom to rotate inside the medicine tube 14. The rotation of the rotating column 15 will cause the connecting shaft 18 at its bottom to rotate synchronously. The connecting shaft 18 will further drive the bottom connector 19 to rotate, and the droppers 20 on both sides of the connector 19 will be flung, thereby uniformly spraying the medicine into the culture glass 2. The uniform spraying of the medicine can make the concentration of these medicines in the water more uniform, and to a certain extent avoid the adverse effects of excessive local water quality changes on the hatching of fish eggs. The uniform medicine helps to maintain the stability of the hatching environment.
[0028] Working Principle: First, when oxygenation is needed for the fish eggs inside the culture glass 2, the oxygen pump 3 is activated. The oxygen pump 3 outputs oxygen to the air supply pipe 4, which then flows through the pipe and connector 5, simultaneously entering the aeration stone 6. This increases the dissolved oxygen content in the water, providing sufficient oxygen for the hatching of the fish eggs. The aeration stone 6 is attached to the inside of the culture glass 2 by suction cups 8 for stability. The position of the aeration stone 6 allows for direct oxygen injection into the middle layer of the culture glass 2, rather than direct aeration of the fish eggs through traditional aeration holes. This allows oxygen bubbles to enter the culture glass 2 more gently, avoiding significant damage to the fish eggs and reducing the breakage rate. Simultaneously, the sponge ring 7 on the outer layer of the aeration stone 6, due to its pores, can regulate the airflow generated by the aeration device, ensuring a more even distribution of oxygen in the hatching water and improving oxygenation. To improve gas utilization efficiency, when it is necessary to inject medicine into the fish eggs inside the culture glass 2, the electric push rod 12 is activated. The electric push rod 12 outputs power to the push platform 13, which slides horizontally inside the slide 11. The displacement of the push platform 13 causes the top connecting platform 16 to move synchronously. When the connecting platform 16 touches the side platform 10, it is pushed, and the pulley 17 slides on the side wall of the side platform 10. The connecting platform 16 changes its own angle, causing the rotating column 15 at its bottom to rotate inside the medicine tube 14. The rotation of the rotating column 15 will cause the connecting shaft 18 at its bottom to rotate synchronously. The connecting shaft 18 further drives the bottom connecting piece 19 to rotate. The droppers 20 on both sides of the connecting piece 19 are then flung, uniformly spraying the medicine solution onto the culture glass 2. Uniform spraying of the medicine solution can make the concentration of these drugs in the water more uniform, avoiding excessive local water quality changes that may adversely affect the hatching of fish eggs. Uniform medicine solution helps to maintain the stability of the hatching environment.
