Description

Technical Field

[0001] This invention relates to the field of fish egg breeding and aquaculture technology, specifically to an automatic collection and separation device for fertilized eggs of the wavy-lipped fish. Background Technology

[0002] The wavy-lipped wrasse is a fish belonging to the genus *Croton* in the family Labridae of the order Perciformes. It is also known as the wavy-lipped wrasse, the dragon king wrasse, the sea king wrasse, and the Napoleon wrasse. The wavy-lipped wrasse mainly inhabits steep outer reef slopes and canyon slopes. Its breeding season is from April to July, and it can lay 80,000 to 120,000 eggs. The wavy-lipped wrasse is a national second-class protected fish, and its artificial breeding technology is of great significance to marine fisheries and species conservation. In Chinese patent CN222396655U, entitled "An Integrated Device for Collecting and Hatching Fish Eggs of the Light-lipped Fish", the patent describes an egg-collecting frame for collecting fish eggs and an egg-laying frame for broodstock to lay eggs. The egg-laying frame, egg-collecting frame, and water-storing frame are progressively larger and are stacked in sequence from top to bottom, forming a three-layered structure from the inside out. The egg-laying frame is equipped with an egg-laying device with a gravel-like rough surface. The bottom of the egg-laying frame has a first hole that allows fish eggs to pass through, and the bottom of the egg-collecting frame has a second hole that allows water to pass through. This invention has a simple structure, is easy to use, and can easily separate broodstock and fertilized eggs. After the fertilized eggs hatch, it can facilitate the transfer of fry, improve the hatching rate, and increase the survival rate of offspring. However, existing technologies cannot separate impurities from fertilized fish eggs during collection, requiring subsequent sorting of the fertilized eggs, resulting in low work efficiency. This is especially true in large-volume seawater breeding ponds where the density of fertilized eggs is low, they are highly buoyant and dispersed, making it difficult for existing technologies to achieve efficient centralized collection. Furthermore, existing technologies are prone to damaging fish eggs during collection, failing to effectively protect them. Summary of the Invention

[0003] This invention provides an automatic collection and separation device for fertilized eggs of the wavy-lipped croaker, which can effectively solve the problems in the prior art mentioned above, where impurities cannot be separated from fertilized eggs during egg collection, and subsequent sorting of fertilized eggs is still required, resulting in low work efficiency. Especially in large-volume seawater breeding ponds, the density of fertilized eggs is low, their buoyancy is strong and they are dispersed, making it difficult for existing technologies to achieve efficient centralized collection. Furthermore, existing technologies often result in the eggs being easily damaged during collection, failing to effectively protect them.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic collection and separation device for fertilized eggs of the wavy-lipped fish, comprising a layered cylinder, wherein a collection and layering component is provided inside and at the top of the layered cylinder, and the collection and layering component includes a collection cover; A collection hood is installed at the top of the layered cylinder, and a sealing base plate is connected to the bottom of the collection hood.

Several guide vanes are welded to the inner side of the vortex tube. A blue light ring is installed on the top of the collection hood. A conical tube is connected to the bottom of the cyclone tube inside the stratification cylinder. A filter cylinder is connected to the bottom of the stratification cylinder. Two assembly ports are opened on one side of the filter cylinder. A sealing frame is embedded inside the assembly port. An isolation net is connected to the bottom of the sealing frame inside the filter cylinder.

[0005] According to the above technical solution, a driven gear is connected to the bottom of the outer side of the cyclone tube, a waterproof motor is installed at the bottom of the sealing base plate, and a drive gear is connected to the output end of the waterproof motor. The drive gear meshes with the driven gear.

[0006] According to the above technical solution, a gear box is installed on the top of the layered cylinder near the cyclone tube, and the gear box is located outside the drive gear and the driven gear.

[0007] According to the above technical solution, a transparent plate is installed on one side of the layered cylinder, and scale lines are provided on the surface of the transparent plate. A counterweight is installed at the bottom of the inner side of the filter cylinder.

[0008] According to the above technical solution, one side of the filter cylinder is connected to both ends of the three-way pipe, the two ends of the three-way pipe are respectively located on top of two isolation nets, and the other end of the three-way pipe is connected to the pumping end of the sewage pump.

[0009] According to the above technical solution, the layered cylinder is provided with an egg transfer and storage assembly inside and outside, and the egg transfer and storage assembly includes a bubble generator; A bubble generator is installed on one side of the layered cylinder at the top of the filter cylinder. The air inlet of the bubble generator is connected to one end of the air supply pipe, and the other end of the air supply pipe passes through the layered cylinder and is connected to the air outlet of an external air pump. A transfer interface is connected to the top of one side of the layered cylinder. An egg storage tank is installed on one side of the outer layer of the layered cylinder. A sealing cap is placed on the top of the egg storage tank. A delivery pipe is connected between the top of the sealing cap and the transfer interface. An oxygenation pump is installed at the bottom inside the egg storage tank.

[0010] According to the above technical solution, a constant temperature heater is installed at the bottom of the egg storage tank, and the outside of the egg storage tank is covered with an insulation layer.

[0011] According to the above technical solution, a collection net is movably embedded inside the egg storage tank, and an overflow pipe is connected to the top of one side of the egg storage tank, with one end of the overflow pipe penetrating the insulation layer.

[0012] According to the above technical solution, the water control valve is an electrically controlled valve, and the input terminals of the water control valve, waterproof motor, blue light ring, sewage pump, bubble generator, constant temperature heater and oxygenation pump are electrically connected to the output terminal of an external power supply through a controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a stratified collection component, the blue light ring emits low-intensity blue light during fish egg collection. Utilizing the fish's phototaxis, it attracts them to spawn near the collection hood. Based on the external water pressure, a control valve regulates the water flow rate, causing water from the breeding tank to enter the collection hood tangentially in a slow-flowing manner. This creates a vortex inside the hood, drawing the floating fish eggs from the breeding tank into the collection hood. Inclined guide vanes inside the vortex tube further promote vortex formation, allowing the fish eggs to follow the vortex into the tube. Inside the conical tube, the eggs are discharged from the bottom of the conical tube and enter the bottom of the stratification cylinder. The fertilized eggs, unfertilized eggs, and impurities are blocked by the isolation net. Utilizing the buoyancy difference between the fertilized and unfertilized eggs of the wavy-lipped fish, the fertilized eggs float to the top of the stratification cylinder after entering the cylinder, while the unfertilized eggs and impurities remain at the bottom of the stratification cylinder, thus completing the screening of fish eggs. Compared with existing technologies, the screening efficiency is high, reducing manual labor costs. Moreover, the fish eggs are gathered by the water flow, which will not damage the fish eggs and ensure the quality of the screened fertilized eggs. When it is necessary to speed up the collection of fish eggs, the waterproof motor is started. Under the driving action of the drive gear and the driven gear, the waterproof motor drives the cyclone tube to rotate. The rotation of the cyclone tube drives the guide vanes to rotate, which speeds up the cyclone and thus increases the collection speed of fish eggs. When a large amount of unfertilized eggs and impurities accumulate inside the filter cartridge, the sewage pump operates, and the unfertilized eggs and impurities are discharged from the stratified cartridge through the three-way pipe. The isolation net is connected to the sealing frame, and the isolation net and sealing frame can be removed from the assembly port, making it convenient to clean the isolation net later. The device is convenient and quick to clean.

[0014] 2. Equipped with an egg transfer and storage component, after the fertilized eggs are layered, the bubble generator delivers microbubbles into the layering cylinder. As the microbubbles are delivered, the pressure inside the layering cylinder increases. Under the action of the pressure difference, the water at the top of the inner side of the layering cylinder is delivered into the egg storage tank through the transfer interface and the delivery pipe. The fertilized eggs also enter the egg storage tank with the water flow, completing the collection and storage of the fertilized eggs. No manual transfer and storage is required, further reducing labor costs. The egg storage tank has a movable collection net inside. Fish eggs that enter the egg storage tank are placed inside the collection net. When it is necessary to remove the fish eggs from the tank, the sealing cover is removed, and the collection net can be lifted to remove all the fish eggs inside the tank, which is more convenient and faster. The constant temperature heater can heat the egg storage tank, so that the water inside the egg storage tank is always at a suitable temperature for fertilized eggs. The oxygen pump delivers oxygen into the egg storage tank to ensure the dissolved oxygen level of the water, which greatly improves the hatching rate of fertilized eggs.

[0015] In summary, the collection and stratification component can gather and collect fish eggs inside the breeding pond, and then perform stratification and screening. The transfer and storage component can transfer the fertilized eggs after stratification and screening from the breeding pond to outside the breeding pond. The fertilized eggs are transported by water flow throughout the process, which fully protects the fertilized eggs. Compared with existing technologies, the collection speed of fertilized eggs is faster and the quality of fertilized eggs is higher. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-7 As shown, the present invention provides a technical solution for an automatic collection and separation device for fertilized eggs of the wavy-lipped fish, including a layered cylinder 1. The layered cylinder 1 is provided with a collection and layering assembly 2 inside and at the top. The collection and layering assembly 2 includes a collection cover 201, a sealing bottom plate 202, a tangential pipe 203, a water control valve 204, a vortex pipe 205, a driven gear 206, a waterproof motor 207, a drive gear 208, a gear box 209, a blue light ring 210, a conical pipe 211, a transparent plate 212, a filter cylinder 213, an assembly port 214, a sealing frame 215, an isolation net 216, a counterweight 217, a three-way pipe 218, a sewage pump 219, and a guide vane 220. A collection hood 201 is installed on the top of the layering cylinder 1. A sealing base plate 202 is connected to the bottom of the collection hood 201. One side of the collection hood 201 is connected to one end of a tangential pipe 203. A water control valve 204 is connected in the middle of the tangential pipe 203. A vortex tube 205 is rotatably installed on the top of the layering cylinder 1. The top of the vortex tube 205 passes through the sealing base plate 202 and is rotatably connected to the sealing base plate 202. Several guide vanes 220 are welded to the inner side of the vortex tube 205. A driven gear 206 is connected to the bottom of the outer side of the vortex tube 205. A waterproof motor 207 is installed at the bottom of the sealing base plate 202. A drive gear 208 is connected to the output end of the waterproof motor 207. The drive gear 208 meshes with the driven gear 206. Under the action of gear connection, when the waterproof motor 207 is started, the waterproof motor 207 can drive the vortex tube 205 to rotate. The rotation of the vortex tube 205 can increase the vortex speed of the water inside the vortex tube 205. A gear box 209 is installed on the top of the layered cylinder 1 near the vortex tube 205. The gear box 209 is located outside the drive gear 208 and the driven gear 206. The gear box 209 can isolate the drive gear 208 and the driven gear 206. When the drive gear 208 and the driven gear 206 rotate, it can prevent the fish eggs in the water from being damaged by the rotation of the gears. A blue light ring 210 is installed on the top of the collection hood 201. Inside the stratification cylinder 1, a conical tube 211 is connected to the bottom of the cyclone tube 205. A transparent plate 212 is installed on one side of the stratification cylinder 1, with scale lines on its surface, allowing observation of the stratification inside the stratification cylinder 1. A filter cylinder 213 is connected to the bottom of the stratification cylinder 1. Two assembly ports 214 are opened on one side of the filter cylinder 213, with a sealing frame 215 embedded inside each port. A separation net 216 is connected to the bottom of the sealing frame 215 inside the filter cylinder 213. One side of the filter cylinder 213 is connected to both ends of a three-way pipe 218, with each end of the three-way pipe 218 located on top of the two separation nets 216. The other end of the three-way pipe 218 is connected to the water intake end of the sewage pump 219. The separation nets 216 are made of food-grade stainless steel, with the top separation net 216 having a pore size of 0.8mm and the bottom separation net 216 having a smaller pore size. The aperture is 0.3mm. When the swirling flow enters the layered cylinder 1 from the bottom of the conical tube 211, the top isolation net 216 can block fertilized eggs, unfertilized eggs and impurities. The fertilized eggs of the wavy-lipped fish contain oil globules and have good buoyancy, so they are buoyant eggs. The unfertilized eggs do not contain oil globules and have poor buoyancy, so they are sinking eggs. The fertilized eggs and unfertilized eggs will be separated in the water. After the fertilized eggs enter the layered cylinder 1, they will quickly float to the top of the inner side of the layered cylinder 1. The unfertilized eggs with poor buoyancy and larger impurities will remain at the top of the top isolation net 216. Smaller impurities pass through the top isolation net 216 and enter the space between the two isolation nets 216. When the sewage pump 219 is running, it can discharge the unfertilized eggs and impurities from the layered cylinder 1. A counterweight 217 is installed at the bottom of the inner side of the filter cylinder 213. The counterweight 217 is located at the bottom of the device, which makes the center of gravity of the device lower and makes the device stand stably in the breeding pond. The layered cylinder 1 is equipped with an egg transfer and storage assembly 3 inside and outside. The egg transfer and storage assembly 3 includes a bubble generator 301, an air supply pipe 302, a transfer interface 303, an egg storage bucket 304, a collection net bucket 305, a sealing cover 306, a delivery pipe 307, a heat preservation layer 308, an overflow pipe 309, a constant temperature heater 310, and an oxygenation pump 311. A bubble generator 301 is installed on one side of the layered cylinder 1 at the top of the filter cylinder 213. The air inlet of the bubble generator 301 is connected to one end of the air supply pipe 302. The other end of the air supply pipe 302 passes through the layered cylinder 1 and is connected to the air outlet of the external air supply pump. A transfer interface 303 is connected to the top of one side of the layered cylinder 1. An egg storage tank 304 is installed on one side of the outer layer of the layered cylinder 1. A sealing cover 306 is placed on the top of the egg storage tank 304. A conveying pipe 307 connects the top of the sealing cover 306 to the transfer interface 303. An oxygenation pump 311 is installed at the bottom inside the egg storage tank 304. A constant temperature heater 310 is installed at the bottom of the egg storage tank 304. An insulation layer 308 covers the outside of the egg storage tank 304. The constant temperature heater 310 can heat the egg storage tank 304, keeping the water inside the egg storage tank 304 at a suitable temperature for fertilized eggs, thereby improving the hatching rate of fertilized eggs. The insulation layer 308 can reduce... Heat dissipation is achieved through the internal movement of a collection net 305 within the egg storage tank 304. Fish eggs entering the egg storage tank 304 are housed within the collection net 305. When fish eggs need to be removed from the tank, the sealing cap 306 is removed, and the collection net 305 is lifted to remove all the fish eggs from the tank. An overflow pipe 309 is connected to the top of one side of the egg storage tank 304, with one end of the overflow pipe 309 penetrating the insulation layer 308. When the water level inside the egg storage tank 304 reaches the position of the overflow pipe 309, water can be discharged from the overflow pipe 309, keeping the water level inside the egg storage tank 304 stable at all times. The water control valve 204 is an electrically controlled valve. The input terminals of the water control valve 204, waterproof motor 207, blue light ring 210, sewage pump 219, bubble generator 301, constant temperature heater 310 and oxygenation pump 311 are electrically connected to the external power supply output terminal through the controller. The controller can control the various electrical components of the device, which facilitates the automatic control of the equipment.

[0020] The working principle and usage process of this invention: When in use, the layered cylinder 1 is placed inside the breeding pool, and the counterweight 217 is located at the bottom of the device, so that the layered cylinder 1 stands stably in the breeding pool. The sewage pump 219, the egg storage tank 304 and the air pump are installed outside the breeding pool. The collection cover 201 and the sealing bottom plate 202 are made of transparent plastic and are located at the water surface of the breeding pool, so that the water level inside the breeding pool is higher than that of the tangential pipe 203. When collecting fish eggs, turn on the blue light ring 210. The blue light ring 210 emits low-intensity blue light, utilizing the fish's phototaxis to induce them to lay eggs near the collection cover 201. Open the water control valve 204. Based on the external water pressure, the water control valve 204 controls the water flow rate, allowing water from the breeding tank to enter the collection cover 201 in a slow flow. The slow-flowing water enters the collection cover 201 tangentially, forming a swirling current inside the collection cover 201. Driven by the water flow, the fish spawn. Fish eggs floating in the pool enter the collection hood 201. The swirling current inside the collection hood 201 causes the fish eggs to move closer to the center of the collection hood 201. When the water level inside the collection hood 201 is higher than the top of the swirling pipe 205, water will flow into the swirling pipe 205. The swirling pipe 205 is equipped with inclined guide vanes 220 to promote the formation of swirling current. The fish eggs follow the swirling current into the swirling pipe 205 and the conical pipe 211, and finally are discharged from the bottom of the conical pipe 211 into the bottom of the inner side of the layered cylinder 1. The diameter of the fish eggs is larger than the mesh diameter of the top isolation net 216. The top isolation net 216 blocks fertilized eggs, unfertilized eggs, and impurities. The fertilized eggs of the wavy-lipped fish contain oil globules, giving them good buoyancy, making them buoyant eggs. The unfertilized eggs do not contain oil globules, giving them poor buoyancy, making them sinking eggs. Fertilized and unfertilized eggs will separate in the water. After entering the stratification cylinder 1, the fertilized eggs will quickly float to the top of the inner side of the stratification cylinder 1. The unfertilized eggs with poor buoyancy and larger impurities will remain at the top of the top isolation net 216 inside the filter cylinder 213. Smaller impurities will pass through the top isolation net 216. The off-net 216 enters the space between the two isolation nets 216. At this time, the fertilized eggs are located at the top inside the layered cylinder 1, while the unfertilized eggs and impurities are located at the bottom inside the layered cylinder 1, thus completing the screening of fish eggs. The blue light attracts fish and the water flow gathers and collects the fish eggs. Then, the difference in buoyancy is used to screen the fish eggs and impurities. Compared with the existing technology, there is no need for manual screening of fertilized eggs, unfertilized eggs and impurities. The screening efficiency is high, the labor cost is reduced, and the fish eggs are gathered by the water flow without damaging them, thus ensuring the quality of the screened fertilized eggs. When it is necessary to speed up the collection of fish eggs, the waterproof motor 207 is started. Under the driving action of the drive gear 208 and the driven gear 206, the waterproof motor 207 drives the cyclone tube 205 to rotate. The rotation of the cyclone tube 205 drives the guide vane 220 to rotate, thereby speeding up the cyclone speed and increasing the collection speed of fish eggs. When there is a large accumulation of unfertilized eggs and impurities inside the filter cartridge 213, the sewage pump 219 is activated, and the unfertilized eggs and impurities are discharged from the stratified cartridge 1 through the three-way pipe 218. The isolation net 216 is connected to the sealing frame 215. The isolation net 216 and the sealing frame 215 can be removed from the assembly port 214, which facilitates the subsequent cleaning of the isolation net 216. The device is convenient and quick to clean. After the fertilized eggs are separated into layers, the bubble generator 301 and the external air pump are started. The air delivered by the external air pump is delivered into the bubble generator 301 through the air supply pipe 302. The bubble generator 301 delivers microbubbles into the layering cylinder 1. As the microbubbles are delivered, the pressure inside the layering cylinder 1 increases. Under the action of the pressure difference, the water at the top of the inner side of the layering cylinder 1 is delivered into the egg storage tank 304 through the transfer port 303 and the delivery pipe 307. The fertilized eggs also enter the egg storage tank 304 with the water flow, completing the collection and storage of the fertilized eggs. There is no need for manual transfer and storage, which further reduces the labor cost. An egg storage tank 304 has a movable collection net 305 embedded inside. Fish eggs that enter the egg storage tank 304 are located inside the collection net 305. When it is necessary to remove the fish eggs from the tank, the sealing cover 306 is removed, and the collection net 305 is lifted to remove all the fish eggs from the tank, which is more convenient and faster. When the water level inside the egg storage tank 304 reaches the overflow pipe 309, the water can be discharged from the overflow pipe 309, so that the water level inside the egg storage tank 304 is always stable. The constant temperature heater 310 can heat the egg storage tank 304, so that the water inside the egg storage tank 304 is always at a suitable temperature for fertilized eggs. The oxygen pump 311 delivers oxygen to the egg storage tank 304 to ensure the dissolved oxygen content of the water and greatly improve the hatching rate of fertilized eggs. The collection and stratification component 2 can gather and collect fish eggs inside the breeding pond, and then perform stratification and screening. The transfer and storage component 3 can transfer the fertilized eggs after stratification and screening from the breeding pond to outside the breeding pond. The fertilized eggs are transported by water flow throughout the process, which fully protects the fertilized eggs. Compared with the existing technology, the collection speed of fertilized eggs is faster and the quality of fertilized eggs is higher.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
