Technical Field

[0001] This utility model relates to the field of fish egg incubation equipment, specifically a fish egg incubation equipment with water flow regulation. Background Technology

[0002] The mandarin fish (Gastrodon scutellarioides) is a distinctive economic fish species widely distributed in most freshwater areas. Its delicious flavor and rich nutritional value make it highly popular with consumers, resulting in a promising market prospect. To protect the ecological environment, artificial breeding of mandarin fish has become a sought-after new aquaculture industry.

[0003] The fertilized eggs of the mandarin fish are spherical and orange-yellow. They are sinking eggs and non-adhesive. During the incubation process, the fertilized eggs of the mandarin fish are placed in a water tank for incubation.

[0004] However, the fertilized eggs of the chub fish tend to accumulate at the bottom or in corners, causing them to stick together, become oxygen-deficient, and moldy, thus affecting the hatching effect. Therefore, a fish egg hatching device with water flow regulation is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a fish egg incubation device with water flow regulation.

[0010] Preferably, the drain pipe is equipped with a water outlet valve, and a rubber plug is detachably installed on the first drain outlet.

[0011] Preferably, the bottom of the incubation ring pool is U-shaped, and the pool wall is smooth.

[0012] The advantages of this utility model are: This invention utilizes an external water supply pipe connected to a water pump to pump oxygen-rich water from the outside into the connecting pipe. The water is then injected into the inlet pipe and sprayed out through nozzles on a ring-shaped pipe. This circulates the water at the bottom of the hatching ring, preventing the fertilized eggs of the mandarin fish from settling and becoming stagnant, which would lead to egg accumulation, adhesion, oxygen deficiency, and mold growth, thus affecting the hatching process. Furthermore, the smooth surface of the hatching ring reduces friction between the fertilized eggs and the ring, preventing damage and ensuring successful hatching.

[0017] 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 scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a fish egg hatching device with water flow regulation. (Refer to...) Figures 1-5A water flow-controlled fish egg hatching device includes a base platform 1; a hatching ring channel 2 is fixedly installed above the base platform 1. The hatching ring channel 2 is used to hatch fertilized eggs of the chub and improve the hatching effect. The hatching ring channel 2 includes an outer ring structure 3 and an inner ring structure 4. The outer ring structure 3 and the inner ring structure 4 are waterproofed to prevent water erosion of the outer ring structure 3 and the inner ring structure 4, which would affect their service life. A hatching ring pool 5 is formed between the outer ring structure 3 and the inner ring structure 4. The hatching ring pool 5 is used for hatching fertilized chub eggs. The hatching process involves circulating the water in the hatching ring pool 5 to prevent the fertilized eggs of the chub from settling and becoming stagnant, which would lead to egg accumulation, oxygen deprivation, and mold growth, thus affecting the hatching effect. An annular hatching trough 6 is located at the bottom of the hatching ring channel 2, and an annular pipe 7 is fixedly installed in the annular hatching trough 6. Multiple nozzles 8 are installed on the annular pipe 7, and the spray surface of the nozzles 8 can be set at various angles to the horizontal plane, including at least -15°, 0°, 45°, and 75°. This allows the nozzles 8 to circulate the water at the bottom of the hatching ring pool 5, preventing the fertilized eggs of the chub from settling. The fertilized eggs of the juvenile fish in the hatching ring pool 5 become stagnant, causing them to accumulate and stick together. This leads to oxygen deprivation and mold growth, affecting the hatching process. The bottom of the hatching ring 2 and the annular hatching tank 6 are each equipped with a first drain outlet 9, and a drain pipe 10 is installed on the first drain outlet 9. After the hatched fry are transferred, the wastewater in the hatching ring 2 can be quickly discharged through the drain pipe 10. The drain pipe 10 facilitates rapid cleaning of the hatching ring 2. An inlet pipe is installed on the annular pipe 7. The inner ring structure 4 and the base platform 1 enclose an overflow pool 11, which is used to drain the wastewater from the hatching ring 2. The water seeps into the hatching ring 2 to prevent water from overflowing when adding water to the hatching ring 2. An outlet 12 is set at the bottom of the overflow pool 11, and an overflow pipe 13 is fixedly installed on the outlet 12. The structure of the overflow pipe 13 ensures the water level of the overflow pool 11 and prevents water from overflowing. The bottom of the hatching ring pool 5 is U-shaped and the walls of the hatching ring pool 5 are smooth. This structure reduces the friction between the fertilized eggs of the chub and the hatching ring pool 5, preventing the fertilized eggs of the chub from being damaged and affecting the hatching of the fertilized eggs.

[0019] Reference Figure 3 and Figure 4A water pump 14 is fixedly installed on the base platform 1. A connecting pipe 15 is fixedly installed at the output end of the water pump 14. A flow control valve 16 is installed on the connecting pipe 15. A water inlet pipe 17 is fixedly installed on the annular pipe 7. A second drain outlet 171 is fixedly installed on the annular pipe 7. The water inlet pipe 17 is connected to the connecting pipe 15. A water inlet valve 18 is installed on the water inlet pipe 17. A drain valve 181 is installed on the second drain outlet 171. By connecting an external water supply pipe to the water pump 14, oxygen-enriched water from the outside is pumped through the water pump 14 to the connecting pipe 15, and water is injected into the water inlet pipe 17. Water is sprayed out through nozzles 8 on the annular pipe 7. At the same time, a second drain outlet 171 is connected to the other end of the annular pipe 7 for drainage. This forms a dual drainage system with the first drain outlet 9, giving the entire device one inlet and two outlets. A drain valve 181 is installed on the second drain outlet 171, which is opened when in use and closed when not in use. When in use, the water sprayed by the nozzles 8 will push the water at the bottom of the hatching ring pool 5 to flow, so as to prevent the fertilized eggs of the chub from sinking into the hatching ring pool 5 and becoming stagnant. This would cause the fertilized eggs to accumulate and stick together, resulting in oxygen deficiency and mold growth, which would affect the hatching effect.

[0020] It should be noted that in actual use, the annular pipe 7 is fixed and sealed to the bottom of the annular hatching tank 6 with cement, with only the nozzle 8 exposed. In addition, after the hatched fry are transferred out, in order to facilitate the cleaning of the mud and sand that may accumulate in the annular pipe 7, a second drain outlet 171 is connected to the other end of the annular pipe 7. This part is for the purpose of understanding the solution of this application.

[0021] Reference Figure 1 and Figure 3 Multiple troughs 19 are provided on the inner ring structure 4. Mounting brackets 20 are fixedly installed on the troughs 19. Filter screens 21 are detachably installed on the mounting brackets 20. The top of the filter screens 21 is on the same horizontal plane as the top of the inner ring structure 4. Through this structure, the chub eggs hatched in the hatching ring channel 2 can be blocked, preventing the chub eggs from entering the overflow pool.

[0022] Reference Figure 3 and Figure 5 A filter 22 is fixedly installed on the nozzle of the nozzle 8. The filter 22 is made of stainless steel to prevent impurities in the water from entering the incubation ring channel 2. A filter screen 23 is fixedly installed above the overflow pipe 13. The filter screen 23 is made of nylon to prevent external debris from entering the overflow pipe 13.

[0023] Reference Figure 3 The drain pipe 10 is equipped with a water outlet valve 24 to control the drain pipe 10 to discharge water, and a rubber plug 25 is detachably installed on the first drain outlet 9. The structure of the rubber plug 25 will prevent fish eggs and fry from entering the first drain outlet 9 during hatching.

[0024] Working principle: By connecting an external water supply pipe to the water pump 14, oxygen-rich water from the outside is pumped to the connecting pipe 15 and injected into the inlet pipe 17. The water is then sprayed out through the nozzle 8 on the annular pipe 7, causing the nozzle 8 to circulate the water at the bottom of the hatching ring pool 5. This prevents the fertilized eggs of the chub from sinking into the hatching ring pool 5 and becoming stagnant, which would cause the fertilized eggs to accumulate and stick together, leading to oxygen deficiency and mold growth, thus affecting the hatching effect. In addition, the walls of the hatching ring pool 5 are designed with a smooth surface. This design reduces friction between the fertilized eggs of the chub and the hatching ring pool 5, preventing damage to the fertilized eggs and affecting their hatching. An overflow pool 11 is formed by the inner ring structure 4 and the base platform 1. The overflow pool 11 is used to allow water in the hatching ring channel 2 to seep out, thus preventing water from overflowing when water is added to the hatching ring channel 2. An outlet 12 is provided at the bottom of the overflow pool 11, and an overflow pipe 13 is fixedly installed on the outlet 12. The structure of the overflow pipe 13 ensures the water level of the overflow pool 11 and prevents water from overflowing. In addition, multiple troughs 19 are opened on the inner ring structure 4, and mounting frames 20 are fixedly installed on the troughs 19. Filter screens 21 are detachably installed on the mounting frames 20. The top of the filter screens 21 is at the same level as the top of the inner ring structure 4. Through this structure, the water quality of the hatching ring channel 2 can be guaranteed, and the chub eggs hatched in the hatching ring channel 2 can be blocked, preventing the chub eggs from entering the overflow pool.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
