Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, specifically to an aquaculture hatching device. Background Technology
[0002] Aquaculture is the practice of raising aquatic economic animals and plants using aquatic waters available for cultivation (including planting), according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, and employing aquaculture technologies and facilities. It is one of the agricultural production sectors.
[0003] Aquaculture is categorized into marine aquaculture and freshwater aquaculture based on the nature of the water body. It is also classified by the species being farmed or cultivated, including fish, shrimp, crabs, shellfish, algae, water chestnuts, lotus, and roots. Through vigorous improvement and utilization of all available and potential aquaculture areas, the aquaculture area has been expanded and the yield per unit area (water body) increased. New fields and approaches to aquaculture have been explored, including factory farming, mechanized farming, high-density warm-water aquaculture, cage farming (including multi-layered cages), artificial reefs, integrated farming, and mixed farming, moving towards intensive management and tapping the potential of aquatic production. With the protection of aquatic resources and the ecological environment, aquaculture has achieved rapid development.
[0004] Fish egg hatching and seedling raising is a crucial stage in fish farming. It is essential to ensure both the survival rate of the fry and the hatching and seedling raising rate. Therefore, hatching devices used in aquaculture are an important type of aquaculture equipment, ensuring that people can obtain better returns in the field of aquaculture.
[0005] When using existing incubation devices, conventional incubation devices require the use of flowing water for incubation and a continuous supply of oxygen to the water. Currently, oxygen supply is usually achieved by directly inserting pipes into the water. In this method, when oxygen is supplied, gas is introduced into the water, which generates bubbles. When these bubbles rise and come into contact with the eggs, they adhere to the outside of the eggs, easily encasing them and affecting the incubation process. Therefore, an aquaculture incubation device is proposed. Summary of the Invention
[0006] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0036] This invention provides an aquaculture hatching device. A driving component rotates a water supply spiral blade, supplying water from an oxygenation tank to the bottom of the hatching tank. Water in the hatching tank overflows from the overflow pipe back into the oxygenation tank, achieving water circulation. An oxygenation mechanism is placed inside the oxygenation tank to oxygenate the tank. Bubbles generated during oxygenation rise directly to the surface within the oxygenation tank. A de-bubbling mechanism is installed inside the return water bend to prevent bubbles from entering the hatching tank. During hatching, this prevents bubbles from trapping the eggs and hindering the hatching process. (See also...) Figures 1-6 It includes: an incubation unit 100, an oxygenation unit 200, and a degassing unit 300.
[0037] The incubation mechanism 100 includes an incubation tank 110, an oxygenation tank 120, an overflow pipe 130, a return water bend 140, a drive component 150, and a water supply spiral blade 160. The top of the side wall is connected to the oxygenation tank 120 through the overflow pipe 130, and the bottom of the side wall of the oxygenation tank 120 is connected to the incubation tank 110 through the return water bend 140. The drive component 150 is provided on the outer wall of the oxygenation tank 120, and the output shaft of the drive component 150 is connected to the water supply spiral blade 160 located in the return water bend 140.
[0038] The incubation tank 110 is a cylindrical container. The top of the oxygenation tank 120 is flush with the top of the incubation tank 110, and the bottom of the oxygenation tank 120 is supported by legs. The drive component 150 is a rotating motor. The incubation tank 110 and the oxygenation tank 120 are interconnected. The return water bend 140 has horizontal pipes at both ends and a vertical pipe in the middle. Air bubbles float in the vertical pipe. The drive component 150 drives the water supply spiral blades 160 to rotate. Under the effect of spiral feeding, the water at the bottom of the oxygenation tank 120 flows into the bottom of the incubation tank 110 through the return water bend 140. As the water level in the incubation tank 110 increases, the water level rises. After rising, the water above the overflow pipe 130 overflows from the overflow pipe 130 and enters the oxygenation tank 120, realizing water circulation and providing the flowing water required for egg hatching. The water flow rate is determined by the rotation speed of the drive component 150 and is adjusted according to the different needs of different fish species.
[0039] The oxygenation mechanism 200 is installed inside the oxygenation tank 120 and connected to the drive component 150. The oxygenation mechanism 200 oxygenates the water in the oxygenation tank 120 to provide the oxygen required for egg hatching. The bubbles generated during oxygen supply rise to the surface, preventing them from entering the hatching tank 110 through the return water bend 140.
[0040] Specifically, the oxygenation mechanism 200 includes an oxygenation hopper 210, an oxygenation shaft 220, an oxygenation driven bevel gear 230, an oxygenation driving bevel gear 240, an oxygenation spiral blade 250, an oxygenation driving gear 260, a speed-changing component 270, an oxygenation fan shaft 280, an oxygenation driven pinion 281, and an impeller 290. A fixing plate 211 connected to the inner wall of the oxygenation tank 120 is provided on the right side of the oxygenation hopper 210. The oxygenation shaft 220 is rotatably connected to the lower part of the inner cavity of the oxygenation hopper 210, and the oxygenation driven bevel gear 230 is provided at the lower end of the oxygenation shaft 220. An oxygenation drive bevel gear 240 is provided on the output shaft of the drive component 150. The oxygenation drive bevel gear 240 is meshed with the oxygenation driven bevel gear 230. An oxygenation drive gear 260 is provided on the upper end of the oxygenation shaft 220. The upper end of the inner cavity of the oxygenation hopper 210 is rotatably connected to the speed change component 270 and the oxygenation fan shaft 280. The oxygenation drive gear 260 is connected to the lower end of the speed change component 270. The lower end of the oxygenation fan shaft 280 is connected to the upper end of the speed change component 270 through the oxygenation driven pinion 281. An impeller 290 is provided on the upper end of the oxygenation fan shaft 280.
[0041] When the output shaft of the drive component 150 rotates, it synchronously drives the oxygenation drive bevel gear 240 to rotate. The oxygenation drive bevel gear 240 meshes and drives the oxygenation driven bevel gear 230 to rotate. The oxygenation driven bevel gear 230 synchronously drives the oxygenation shaft 220 to rotate. The oxygenation shaft 220 synchronously drives the oxygenation spiral blades 250 to rotate. When the oxygenation spiral blades 250 rotate, the water inside is discharged downward into the water body under the action of spiral feeding, thereby forming a cavity in the inner cavity of the oxygenation hopper 210. At the same time, the oxygenation shaft 220 synchronously drives the oxygenation drive gear 260 to rotate. The oxygenation drive gear 260 drives the oxygenation driven pinion 281 to rotate through the speed change component 270. The oxygenation driven pinion 281 drives the impeller 290 to rotate through the oxygenation air shaft 280. The rotation of the impeller 290 drives the airflow. The airflow passes downward through the oxygenation hopper 210 and enters the water body to oxygenate the water body. After oxygenation, the bubbles float to the surface and are discharged.
[0042] The debubbling mechanism 300 is installed inside the return water bend 140 and connected to the drive component 150. The debubbling mechanism 300 causes the bubbles entering the return water bend 140 to float to the top of the longitudinal section of the return water bend 140, thus preventing the bubbles from entering the incubation tank 110.
[0043] Specifically, the bubble mechanism 300 includes a bubble shaft 310, a bubble driven bevel gear 320, a bubble driving bevel gear 330, inclined blades 340, and a conical mesh cover 350. The bubble shaft 310 is rotatably connected to the inner cavity of the return water bend 140. The bubble driven bevel gear 320 is provided at the upper end of the bubble shaft 310. The bubble driving bevel gear 330 is provided at the end of the output shaft of the drive component 150. The bubble driving bevel gear 330 meshes with the bubble driven bevel gear 320. The inclined blades 340 are evenly distributed on the outer wall of the bubble shaft 310. The conical mesh cover 350 is provided outside the inclined blades 340 and is connected to the inner wall of the return water bend 140.
[0044] The output shaft of the drive component 150 synchronously drives the bubble drive bevel gear 330 to rotate. The bubble drive bevel gear 330 meshes and drives the bubble driven bevel gear 320 to rotate. The bubble driven bevel gear 320 synchronously drives the bubble shaft 310 to rotate. The bubble shaft 310 synchronously drives the inclined blade 340 to rotate in a circle. The rotating inclined blade 340 causes the water to rotate, causing the bubbles to gather at the center and float upward. The water without bubbles at the edge flows into the hatching tank 110 through the conical mesh cover 350.
[0045] The speed change component 270 includes a speed change shaft 271, a speed change pinion 272, and a speed change gear 273. The speed change shaft 271 is rotatably connected to the upper end of the inner cavity of the oxygenation hopper 210. The lower end of the speed change shaft 271 is fixedly connected to the speed change pinion 272, which meshes with the oxygenation drive gear 260. The upper end of the speed change shaft 271 is fixedly connected to the speed change gear 273, which meshes with the oxygenation driven pinion 281.
[0046] Among them, the oxygenation drive gear 260 drives the variable speed pinion 272 to rotate, thereby increasing the speed in sequence. The variable speed pinion 272 drives the variable speed large gear 273 to rotate synchronously through the variable speed shaft 271. The variable speed large gear 273 meshes with and drives the oxygenation driven pinion 281 to rotate for a second speed increase, thereby increasing the speed of the impeller 290 and facilitating gas flow.
[0047] Since a large number of air bubbles are present in the oxygenation tank 120 during oxygenation, in order to prevent air bubbles from entering the return water bend 140, oxygenation blades 221 are provided on the lower outer wall of the oxygenation shaft 220. The oxygenation blades 221 are evenly distributed on the lower outer wall of the oxygenation shaft 220. The oxygenation shaft 220 drives the oxygenation blades 221 to rotate, causing the oxygenation blades 221 to stir the water inside the oxygenation tank 120 to form a vortex, which causes the air bubbles to concentrate and float to the center. At the same time, the stirring increases the contact range between water and air, ensuring the oxygenation effect.
[0048] Since the water flows out from the return water bend 140, after discharge, the water will concentrate at the outlet of the return water bend 140 and float upwards, unable to flow evenly. Therefore, a bubble drive bevel gear 360 is provided at the lower end of the bubble shaft 310. A water mixing mechanism 400 located at the bottom of the incubation tank 110 is connected to the bubble drive bevel gear 360. The water mixing mechanism 400 includes a water mixing drive shaft 410, a water mixing drive bevel gear 420, a water mixing driven bevel gear 430, a central shaft 440, a top bevel gear 450, and water mixing blades 460. 410 is rotatably connected inside the return water bend 140. A mixing drive bevel gear 420 is provided at the right end of the mixing drive shaft 410. The mixing drive bevel gear 420 meshes with the bubble drive bevel gear 360. A mixing driven bevel gear 430 is provided at the left end of the mixing drive shaft 410. The central shaft 440 is rotatably connected to the bottom center of the hatching tank 110. A top bevel gear 450 is provided at the top of the central shaft 440. The top bevel gear 450 meshes with the mixing driven bevel gear 430. A uniformly distributed mixing blade 460 is provided on the outer wall of the central shaft 440.
[0049] Among them, the bubble shaft 310 synchronously drives the bubble transmission bevel gear 360 to rotate, the bubble transmission bevel gear 360 meshes and drives the water mixing drive bevel gear 420 to rotate, the water mixing drive bevel gear 420 drives the water mixing driven bevel gear 430 to rotate through the water mixing transmission shaft 410, the water mixing driven bevel gear 430 meshes and drives the top bevel gear 450 to rotate, the top bevel gear 450 synchronously drives the central shaft 440 to rotate, and the central shaft 440 synchronously drives the water mixing blade 460 to rotate, so that the water entering the hatching tank 110 flows upward evenly and fully contacts the eggs, which facilitates the hatching of the eggs.
[0050] Because the rotation of the mixing blade 460 generates a vortex that affects the hatching of eggs, a planetary mixing mechanism 500 is connected to the outside of the mixing blade 460. The planetary mixing mechanism 500 includes an outer gear ring 510, a planetary gear shaft 520, a planetary gear 530, a planetary blade 540, an inner gear ring 550, and an outer blade 560. The outer gear ring 510 is fixedly connected to the outside of the mixing blade 460. The planetary gear shaft 520 is rotatably connected to the bottom of the circumference of the hatching tank 110. The planetary gear 530 is provided on the planetary gear shaft 520. The planetary blade 540 is provided at the top of the planetary gear 530. The inner gear ring 550 is rotatably connected to the bottom of the hatching tank 110. The planetary gear 530 meshes between the outer gear ring 510 and the inner gear ring 550. The outer blade 560 is evenly distributed on the outer wall of the inner gear ring 550.
[0051] Among them, the mixing blade 460 synchronously drives the outer gear ring 510 to rotate, the outer gear ring 510 meshes and drives the planetary gear 530 to rotate, the planetary gear 530 synchronously drives the planetary gear shaft 520 to rotate, the planetary gear shaft 520 synchronously drives the planetary blade 540 to rotate for mixing, and the planetary gear 530 meshes and drives the inner gear ring 550 to rotate, the inner gear ring 550 synchronously drives the outer blade 560 to rotate.
[0052] Since eggs and fry are prone to sinking and getting into the mixing mechanism 400, a support ring 111 is provided on the inner wall of the hatching tank 110. The support ring 111 is provided with a filter screen 600 and a separator 700 distributed vertically. The separator 700 is located above the filter screen 600. The separator 700 includes a separator plate 710, a through hole 720 and a one-way valve 730. The separator plate 710 has evenly distributed through holes 720, and a one-way valve 730 is provided in each through hole 720.
[0053] The filter screen 600 supports the eggs, keeping them and fry in the middle of the hatching tank 110, preventing them from sinking and getting mixed into the mixing mechanism 400. As the water flows upward, it will cause the hatched fish to swim upward. The fish swim through the one-way valve 730 and enter the area above the separator 710, while the eggs do not swim and remain below the separator 710, thus separating the fish and eggs.
[0054] To ensure the quality of the water for egg hatching, a filter element 131 is installed inside the overflow pipe 130, and a sealing cover 132 is installed at the top of the overflow pipe 130. The overflow water is filtered through the filter element 131, and the filter element 131 is replaced by opening the sealing cover 132.
[0055] Since the air bubbles rising inside the return water bend 140 are concentrated at the upper inflection point of the return water bend 140, an air vent valve 370 is installed at the upper end of the return water bend 140 to discharge the concentrated gas in the pipe.
[0056] In practical use, the drive component 150 drives the water supply spiral blades 160 to rotate. Under the effect of spiral feeding, water at the bottom of the oxygenation tank 120 flows into the bottom of the incubation tank 110 through the return water bend 140. As the water level in the incubation tank 110 increases, the water level rises. Water that is higher than the overflow pipe 130 overflows from the overflow pipe 130 and enters the oxygenation tank 120, realizing water circulation. The overflow water is filtered by the filter element 131. When the output shaft of the drive component 150 rotates, it synchronously drives the oxygenation drive bevel gear 240 to rotate. The oxygenation drive bevel gear 240 meshes and drives the oxygenation driven bevel gear 230 to rotate. The oxygenation driven bevel gear 230 synchronously drives the oxygenation shaft 220 to rotate. The oxygenation shaft 220 synchronously drives the oxygenation spiral blades 250 to rotate. When the oxygenation spiral blades 250 rotate, under the action of spiral feeding, the water inside is discharged downward into the water body, thus forming a cavity inside the oxygenation hopper 210. Simultaneously, the oxygenation shaft 220 drives the oxygenation drive gear 260 to rotate. The oxygenation drive gear 260 drives the oxygenation driven pinion 281 to rotate through the speed change component 270. The oxygenation driven pinion 281 drives the impeller 290 to rotate through the oxygenation fan shaft 280. The rotation of the impeller 290 drives the airflow. The airflow passes downward through the oxygenation hopper 210 and enters the water body to oxygenate it. Simultaneously, the output shaft of the drive component 150 drives the bubble drive bevel gear 330 to rotate. The bubble drive bevel gear 330 meshes and drives the bubble driven bevel gear 320 to rotate. The bubble driven bevel gear 320 simultaneously drives the bubble shaft 310 to rotate. The bubble shaft 310 simultaneously drives the inclined blades 340 to rotate circumferentially. The rotating inclined blades 340 cause the water body to rotate, causing the bubbles to gather at the center and float upward. The water body without bubbles at the edge flows into the hatching tank 110 through the conical mesh cover 350, preventing bubbles from entering the hatching tank 110.The bubble shaft 310 synchronously drives the bubble drive bevel gear 360 to rotate. The bubble drive bevel gear 360 meshes with and drives the mixing drive bevel gear 420 to rotate. The mixing drive bevel gear 420 drives the mixing driven bevel gear 430 to rotate via the mixing drive shaft 410. The mixing driven bevel gear 430 meshes with and drives the top bevel gear 450 to rotate. The top bevel gear 450 synchronously drives the central shaft 440 to rotate. The central shaft 440 synchronously drives the mixing blade 460 to rotate. The mixing blade 460 synchronously drives the external gear ring 510 to rotate. The external gear ring 510 meshes with and drives the planetary gear 530 to rotate. The planetary gear 530 synchronously drives the planetary gear shaft 520 to rotate. The planetary blades 540 rotate synchronously to mix the water, and the planetary gears 530 mesh to drive the internal gear ring 550 to rotate. The internal gear ring 550 synchronously drives the outer blades 560 to rotate, achieving a three-layer rotational mixing effect of the mixing blades 460, planetary blades 540, and outer blades 560. This ensures that the water entering the bottom of the hatching tank 110 flows evenly upwards to contact the eggs. The filter screen 600 supports the eggs, keeping them and the fry in the middle of the hatching tank 110, preventing them from sinking and getting mixed into the mixing mechanism 400. Because the water flows upwards, it encourages the hatched fish to swim upwards. The upstream fish swim through the one-way valve 730 and enter the spacer above the separator 710, separating the fish from the eggs.
