Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture and relates to an automatic constant-temperature internal circulation artificial hatching device. Background Art

[0002] With the rapid development of aquaculture, artificial hatching technology has played an important role in improving the reproductive efficiency and population of fish. As a popular ornamental fish and research subject, there is an increasing demand for efficient hatching of the fish under artificial conditions. Traditional artificial hatching methods usually involve the use of specially designed hatching ponds or containers, which can provide relatively stable environmental conditions, such as suitable water quality, light and appropriate water flow, to promote the healthy development of fish eggs.

[0003] In the prior art, the artificial hatching process of the heterostomous new light lip fish mainly relies on the control of key parameters such as water temperature and water quality. The ideal incubation temperature range is generally between 22°C and 25°C, which helps to speed up the development of embryos and improve the hatching rate. However, in actual operations, it is often difficult to achieve uniform and precise water temperature control. Especially in larger-scale hatching systems, due to uneven distribution of heating equipment or low heat conduction efficiency, there are temperature differences in local areas, which affects the overall hatching effect. In addition, a low temperature environment will significantly reduce the hatching success rate and increase the risk of hatching failure.

[0004] In addition to the problem of temperature control, sun seeds and other impurities are produced during the incubation process. If these products are not removed in time, the water quality will deteriorate rapidly, leading to the accumulation of harmful substances, which will seriously threaten the development of fertilized eggs. At present, the main means of dealing with these problems is to change the water regularly, but this is not only time-consuming and labor-intensive, but also causes a huge waste of water resources. Frequent water changes may also cause water temperature fluctuations, further affecting the stability of incubation. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic constant temperature internal circulation artificial incubation device, which adopts a constant temperature internal circulation method for incubation, can accurately and evenly control the water temperature, and can effectively purify the water quality during the circulation process, thereby ensuring the stability of the development conditions of the fertilized eggs and making the incubation process more stable.

[0006] In order to solve the above technical problems, the present invention provides an automatic constant temperature internal circulation artificial incubation device, comprising an incubation pool, a water treatment tank is arranged on one side of the incubation pool, a water absorption main pipe is arranged in the water treatment tank, a plurality of suction pipes connected with the water absorption main pipe are arranged at the bottom of the incubation pool, a plurality of suction holes are opened at the bottom of each suction pipe, a water filtering device is arranged in the water treatment tank, the water absorption main pipe is connected with the inlet end of the water filtering device, a disinfection box is arranged in the water treatment tank, a plurality of ultraviolet disinfection lamps are arranged in the disinfection box, the outlet end of the water treatment device is connected with the inlet end of the disinfection box through a first guide pipe, a heating box is arranged in the water treatment tank, an electric heating pipe is arranged in the heating box, and the outlet end of the disinfection box is connected with the inlet end of the heating box through a second guide pipe;

[0007] A circulating water pump is arranged in the water treatment tank, the inlet end of the circulating water pump is connected with the outlet end of the heating box through a third guide pipe, the outlet end of the circulating water pump is connected with a circulating main pipe, horizontal slide rails are arranged on both sides of the upper end of the incubation pool parallel to the water treatment tank, a plurality of water spraying pipes are slidably connected to the two horizontal slide rails, both ends of each water spraying pipe are provided with sliders slidably connected to the corresponding horizontal slide rails, a plurality of water spraying holes distributed along the length direction of each water spraying main pipe are opened on the lower side, and one end of each water spraying pipe close to the water treatment tank is connected with the circulating main pipe through a connecting hose.

[0008] By adopting the above technical solution, the circulating water pump is started, and the water at the bottom of the hatching pool is sucked through the suction pipe, and the impurities precipitated at the bottom are also sucked into the suction pipe, and then enter the water filtration equipment through the water suction main pipe for water filtration. After the water filtration is completed, it enters the disinfection box for ultraviolet disinfection through the ultraviolet disinfection lamp, and then enters the heating box for heating. After heating, the water flows into the sprinkler pipe through the circulation main pipe and the connecting hose, and sprays normal temperature water or warm water into the hatching pool through the sprinkler hole. During the spraying process, the oxygen content of the water can be effectively increased to meet the oxygen demand during the hatching process. If you need to check the development of the fertilized eggs or take and place objects during the process, you can push the sprinkler pipe to slide so that it does not block the operation. After completion, pull the sprinkler pipe back to its original position.

[0009] The present invention is further configured as follows: the water filtration equipment includes a coarse filter cartridge and a fine filter cartridge, the water absorption main pipe is connected to the lower part of the coarse filter cartridge, the inner wall of the lower part of the coarse filter cartridge is provided with a plurality of spiral guide blades, the middle part of the coarse filter cartridge is provided with a plurality of circumferentially distributed sedimentation inclined plates, the inclination direction of the sedimentation inclined plates is the same as the spiral direction of the spiral guide blades, the upper end of the coarse filter cartridge is provided with a primary filter element, the fine filter cartridge is provided with a microporous filter element, the primary filter element is connected to the inlet end of the fine filter cartridge through a filter water pipe, and the microporous filter element is connected to the first guide pipe.

[0010] By adopting the above technical scheme, after the water enters the coarse filter cylinder, it slowly flows upward in a vortex shape under the action of the sedimentation inclined plate and the spiral guide blades. Impurities are more easily settled to the bottom during the vortex flow. After entering the gap of the sedimentation inclined plate, due to the inclined setting of the sedimentation inclined plate, the unsettled impurities are again settled on the sedimentation inclined plate during the rising process, and are settled downward to the bottom of the coarse filter cylinder along with the sedimentation inclined plate. The degree of sedimentation is related to the inclination and height of the sedimentation inclined plate. The higher the height, the better the sedimentation filtration effect. Subsequently, a small amount of unsettled tiny particles are filtered through the primary filter element, and then after entering the fine filter cylinder, the particulate impurities in the water are further filtered through the microporous filter element.

[0011] The present invention is further configured such that the lower portion of the coarse filter cartridge is externally connected to a sewage pipe, and a valve is provided on the sewage pipe.

[0012] The present invention is further configured such that a plurality of U-shaped cover plates for covering the suction pipes are arranged at the bottom of the incubation pool, and the upper end of each U-shaped cover plate is a mesh plate.

[0013] The present invention is further configured such that the lower part of the hatching pool is connected with a drain pipe, and a valve is arranged on the drain pipe.

[0014] The present invention is further configured such that a temperature sensor is provided in the incubation pool.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, the present invention utilizes circulating water for seedling hatching, and the water body is filtered and purified during the water circulation process, so that the water body can always remain clean, effectively preventing the fry from getting sick, while also avoiding the trouble of changing water, saving time and effort, and at the same time, during the water circulation process, the water can be continuously heated, so that the water body in the hatching pool always maintains a suitable temperature state.

[0017] Secondly, the present invention circulates water into the hatching pool by spraying, which can effectively increase the oxygen content of the water body to meet the oxygen demand during the hatching of fry, and the spraying method covers the entire water surface, making the oxygenation more uniform and evenly raising the water temperature;

[0018] Third, when coarsely filtering water, using the sedimentation inclined plate in the coarse filter cylinder for auxiliary sedimentation can effectively promote the precipitation of impurities to the bottom of the coarse filter cylinder. Compared with using a filter net, the water obtained by precipitation is purer and the separation effect of impurities is better.

[0019] Fourthly, the water sprinkling pipe of the present invention is designed to be slidable, so that when fish eggs are placed, the water sprinkling pipe can be moved to one side so as not to block the operation when testing or taking out the fry. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of U-shaped cover plates 8 for covering the suction pipes 6 are arranged at the bottom of the hatching pool 1. The upper end of each U-shaped cover plate 8 is a mesh plate, so that the residual bait and feces produced during the hatching and seedling raising process can be isolated through the U-shaped cover plate 8 after sinking to the bottom of the pool. A water filtering device is arranged in the water treatment tank 4, and the water absorption main pipe 5 is connected with the inlet end of the water filtering device. A disinfection box 9 is arranged in the water treatment tank 4, and a plurality of ultraviolet disinfection lamps 10 are arranged in the disinfection box 9. The outlet end of the water treatment device is connected with the inlet end of the disinfection box 9 through a first guide pipe 11. A heating box 12 is arranged in the water treatment tank 4, and a plurality of electric heating tubes 13 are arranged in the heating box 12. The outlet end of the disinfection box 9 is connected with the inlet end of the heating box 12 through a second guide pipe 14.

[0031] The water filtration device includes a coarse filter cartridge 15 and a fine filter cartridge 16. The water absorption main pipe 5 is connected to the lower part of the coarse filter cartridge 15. The inner wall of the lower part of the coarse filter cartridge 15 is provided with multiple spiral guide blades 17. The middle part of the coarse filter cartridge 15 is provided with multiple circumferentially distributed sedimentation inclined plates 18. The inclination direction of the sedimentation inclined plates 18 is the same as the spiral direction of the spiral guide blades 17. The two cooperate to perform eddy current sedimentation. The upper end of the coarse filter cartridge 15 is provided with a primary filter element 19. The fine filter cartridge 16 is provided with a microporous filter element 20. The lower part of the coarse filter cartridge 15 is connected to a sewage pipe 21. The sewage pipe 21 is provided with a valve 3 to facilitate regular cleaning of impurity precipitation in the coarse filter cartridge 15. The primary filter element 19 is connected to the inlet end of the fine filter cartridge 16 through a filter water pipe 22, and the microporous filter element 20 is connected to the first guide pipe 11.

[0032] A circulating water pump 23 is arranged in the water treatment tank 4, and the inlet end of the circulating water pump 23 is connected to the outlet end of the heating box 12 through a third guide pipe 24, and the outlet end of the circulating water pump 23 is connected to a circulating main pipe 25. A horizontal slide rail 26 is arranged on both sides of the upper end of the incubation pool 1 parallel to the water treatment tank 4, and four water spraying pipes 27 are slidably connected to the two horizontal slide rails 26. A slider 28 slidably connected to the corresponding horizontal slide rail 26 is arranged at both ends of each water spraying pipe 27. A plurality of water spraying holes 29 distributed along the length direction of each water spraying main pipe are opened on the lower side of each water spraying main pipe.

A temperature sensor 31 is arranged in the incubation pool 1, and the water temperature of the incubation pool 1 is monitored in real time by the temperature sensor 31, so as to facilitate real-time intelligent control of the internal water temperature.

[0033] Working principle: Start the circulating water pump 23, so that the water at the bottom of the hatching pool 1 is sucked through the suction pipe 6, and the impurities settled at the bottom are also sucked into the suction pipe 6, and then enter the coarse filter cylinder 15 through the water suction main pipe 5. The upper part of the interior has negative pressure, and under the action of the sedimentation inclined plate 18 and the spiral guide blade 17, it slowly flows upward in a vortex shape. During the vortex flow, impurities are more likely to settle to the bottom. After entering the gap of the sedimentation inclined plate 18, due to the inclined setting of the sedimentation inclined plate 18, the unsettled impurities are again precipitated on the sedimentation inclined plate 18 during the rising process, and are precipitated downward to the bottom of the coarse filter cylinder 15 along with the sedimentation inclined plate 18. The degree of precipitation is related to the inclination and height of the sedimentation inclined plate 18. The higher the height, the better the sedimentation filtration effect. Then, the water passes through the primary filter element 19 to filter out the unprecipitated small particles, and then enters the fine filter cartridge 16 to further filter the particulate impurities in the water through the microporous filter element 20. After the water body is filtered, it enters the disinfection box 9 to be sterilized by ultraviolet light through the ultraviolet disinfection lamp 10, and then enters the heating box 12 for heating. After heating, the water flows into the water spraying pipe 27 through the circulation main pipe 25 and the connecting hose 30, and sprays the normal temperature water or warm water into the hatching pool 1 through the water spraying hole 29. During the spraying process, the oxygen content of the water body can be effectively increased to meet the oxygen demand during the hatching process. If you need to check the development of the fertilized eggs or take and place objects during the process, you can push the water spraying pipe 27 to slide so that it does not block the operation. After completion, pull the water spraying pipe 27 back to its original position.
