Description

Technical Field

[0001] The present invention relates to the technical field of seafood farming, and particularly to a vertical live-keeping farming device for seafood. Background Art

[0002] With the increasing improvement of people's living standards, seafood has gradually made its way onto people's dinner tables; thus, seafood has gradually become a necessary commodity in large shopping malls; to ensure the quality of seafood, there are generally independent farming devices in shopping malls;

[0003] Currently, due to the need to regularly clean the inside of the farming pool, or to change the farming pool for different types of seafood on sale, especially for fish, the replacement is more frequent; the most common treatment method is to transfer the seawater fish in the farming pool to another farming pool, and then directly treat the water body in the farming pool. This method requires a lot of manpower to transfer the fish; and it also requires additional pumping and fishing, resulting in a relatively high cost.

[0004] At the same time, manual pool changing may pose a potential risk of damage to the fish.

[0005] Furthermore, when purifying the water quality of the existing farming pool, first, a part of the water body in the farming pool is pumped out for treatment, and after the treatment is completed, it is injected back into the farming pool. After multiple pumping and injection cycles, the water body in the farming pool meets the farming standards. This purification method is cumbersome, resulting in a relatively long water body treatment cycle. Summary of the Invention

[0010] In a possible implementation, the drainage device is respectively connected to the first live storage tank, the second live storage tank, and the third live storage tank through water pipes to carry out in-tank water circulation; the aeration device is respectively connected to the first live storage tank, the second live storage tank, and the third live storage tank through air pipes to supply oxygen; the refrigeration system is respectively connected to the first live storage tank, the second live storage tank, and the third live storage tank through metal pipes to adjust the in-tank temperature.

[0011] In a possible implementation, the refrigeration system includes an evaporator and a condenser; the evaporator is arranged inside the water storage tank, and the condenser is arranged on the first bottom plate and the second bottom plate, and at the bottom of the third live storage tank; the condenser is arranged at the bottom inside the tank.

[0012] In a possible implementation, the built-in rack includes a front side plate and a rear side plate; the front side plate and the rear side plate are connected by two middle side plates; the tops of the two middle side plates are higher than the front side plate and the rear side plate, and a chute is provided inside the higher part, and the chute matches the left and right sides of the sealing plate; the lower end of the front side plate is movably connected to the front side of the adsorption and purification device, and two connecting rods are fixedly connected to the connection between the lower end of the rear side plate and the middle side plate; the lower ends of the connecting rods are movably connected to the adsorption and purification device.

[0013] In a possible implementation, a hanging hole is provided at the lower end of the front side plate, and a downward notch is provided on one side of the hanging hole close to the rear side plate; a hanging rod is provided on the front side of the adsorption and purification device, and the adsorption and purification device is movably hinged to the lower end of the front side plate by the hanging rod being inserted into the hanging hole from the notch.

[0014] In a possible implementation, a hanging groove is provided on the side of the lower end of the connecting rod close to the front side plate, and a guiding hook is provided below the hanging groove; a magnet is provided above the hanging groove; floating hooks are fixedly arranged at two right-angle positions close to the rear side of the top of the adsorption and purification device; the floating hooks are movably connected to the lower end of the connecting rod.

[0015] In a possible implementation, the floating hook includes a connecting block, and the connecting block is fixedly connected to the adsorption and purification device; a connecting rod is rotatably connected to the inner end of the connecting block, and a floating rod is provided at the upper end of the connecting rod.

[0016] In a possible implementation, the floating rod is made of a magnetic material and has buoyancy.

[0017] In a possible implementation, Step 1: First, drain the water in the first live storage tank through the drainage device, and remove the adsorption and purification device on the built-in rack inside;

[0018] Step 2: Seal the built-in rack inside the second live storage tank with a sealing plate; at this time, the second live storage tank is filled with water, and both Channel 2 and Channel 1 are sealed by the connecting rods on the built-in racks inside the third live storage tank and the second live storage tank.

[0019] Step 3: Start the drainage device to let water flow into the second live-holding pool (the water comes from inside the reservoir); thus, as the water flow increases, the pressure inside the second live-holding pool increases at this time, and the built-in rack will move upward. Since the fish school is placed inside the built-in rack, the adsorption and purification device will drive the fish school upward; when Channel 1 is opened, the water will flow into the first live-holding pool. At this time, the first live-holding pool and the second live-holding pool temporarily form a communicating vessel; when the water is continuously supplied, since the top of the second live-holding pool is sealed by a sealing plate, the water level inside the second live-holding pool will tend to be level with that inside the first live-holding pool at this time. In this way, the built-in rack inside the second live-holding pool will continue to rise until Channel 1 is completely opened; at this time, the fish school will enter the first live-holding pool through Channel 1;

[0020] Step 4: To ensure that more water enters the first live-holding pool, start the aeration device to inject gas into the bottom of the second live-holding pool at this time. The bubbles will move vertically upward due to their own buoyancy and burst at the top of the second live-holding pool; in this way, a cavity will be formed inside the top of the second live-holding pool, that is, inside the built-in rack; at the same time, the original water inside the second live-holding pool will flow into the first live-holding pool, and the fish school will enter the first live-holding pool under the action of the water flow. At the same time, the more gas is injected into the second live-holding pool, the less water there is at the top of the adsorption and purification device at this time, which will force the fish school to enter the first live-holding pool;

[0021] Step 5: When the fish school completely enters the first live-holding pool, insert the adsorption and purification device vertically into the bottom of the built-in rack from the side close to the front side plate inside the built-in rack in the first live-holding pool, and snap the hanging rod into the hanging hole from the notch to be movably hinged to the lower end of the front side plate; during this period, intercept the fish school in the new pool;

[0022] Step 6: Since the floating rod has a certain buoyancy, when the floating rod moves upward, it can drive the adsorption and purification device to flip upward with the hanging hole as the rotation center; at the same time, the adsorption and purification device will automatically drive the fish school to swim upward; when the floating rod continues to move upward and touches the guiding hook, the connecting rod will flip toward the side close to the front side plate at this time. When the floating rod crosses the top of the guiding hook, the connecting rod will be vertical again, so that the floating rod is directly above the hanging groove; at the same time, since the floating rod is made of magnetic material, it will be adsorbed and locked by the magnet at this time; in this way, when converting the seafood in the pool later, or when lifting the built-in rack out of the pool, the adsorption and purification device is fixed below the connecting rod and the front side plate;

[0023] Step 7: Move the built-in rack in the second live-holding pool downward to block Channel 1; empty the water inside the second live-holding pool through the drainage device.

[0024] In a possible implementation manner, a placement bin is opened inside the adsorption and purification device, and fixed grids are movably connected to the upper and lower openings of the placement bin. A plurality of adsorption and purification packages are clamped and fixed inside the fixed grids; activated carbon and white sand are contained inside the adsorption and purification packages.

[0025] Beneficial effects:

[0026] 1. In this solution, the inside of the unit pool is circulated with clean water and sewage in and out, oxygen is supplied to the seafood, and the water temperature is controlled respectively through the drainage device, the aeration device and the refrigeration system; the condenser is arranged at the bottom of the pool and cools down by staying away from the fish area, further reducing the harm to the seafood; the reservoir is used to store standby water, thus preventing fish from dying; at the same time, the evaporator is arranged inside the reservoir. Since heat is generated when the evaporator refrigerates, it can be absorbed by the standby water inside the reservoir in time, and at the same time, the water inside the reservoir can be heated or kept warm. In this way, the energy is reasonably utilized, and it is more energy-saving and environment-friendly;

[0027] 2. In the present invention, the fish group is switched to different pools from bottom to top; by raising the water in the original live storage pool, the swimming range of the fish group is expanded, and then by adding gas, the water in the original live storage pool drops, forcing the fish group to swim to the live storage pool with more water; in this way, through the natural flow of the seafood fish, the damage to the fish group caused by artificial pool switching is avoided; the survival rate of the seafood is greatly improved;

[0028] 3. In the present invention, the fish group is switched to different pools from top to bottom; through gravity, the original water automatically flows into the new live storage pool. Through the natural flow of the seafood fish, the damage to the fish group caused by artificial pool switching is avoided; the survival rate of the seafood is greatly improved;

[0029] 4. In the present invention, the activated carbon inside the adsorption purification package can adsorb impurities in the pool, playing a role in purifying the aquaculture water quality. At the same time, the independent adsorption purification package is convenient to use and can be quickly replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. In addition, in order to describe the present invention more clearly, components not connected to the invention will be omitted from the drawings;

[0051] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0052] Embodiment 1:

[0053] As Figures 1 - 3 shown, this embodiment introduces the specific structure of a vertical live-keeping breeding device for seafood, including a breeding system 1, which is composed of multiple groups of unit ponds 11; inside the unit pond 11, a first live-keeping pond 112, a second live-keeping pond 113, and a third live-keeping pond 114 are arranged in sequence from top to bottom; the first live-keeping pond 112, the second live-keeping pond 113, and the third live-keeping pond 114 are arranged in a stepped manner; a water storage pond 111 is arranged at the bottom of the unit pond 11; a drainage device 2, an aeration device 3, and a refrigeration system 4 are arranged at the rear side of each group of unit ponds 11 close to the water storage pond 111; the drainage device 2, the aeration device 3, and the refrigeration system 4 respectively perform the functions of circulating the inflow and outflow of clean and sewage water inside the unit pond 11, supplying oxygen to seafood, and controlling the water temperature;

[0054] The bottoms of the first live-keeping pond 112 and the second live-keeping pond 113 respectively have a first bottom plate 1121 and a second bottom plate 1131, and the first bottom plate 1121 and the second bottom plate 1131 are arc-shaped; a first channel 1122 is opened near the lower end of the first bottom plate 1121 between the first live-keeping pond 112 and the second live-keeping pond 113; a second channel 1132 is opened near the lower end of the second bottom plate 1131 between the second live-keeping pond 113 and the third live-keeping pond 114; the first channel 1122 and the second channel 1132 are used for allowing fish groups to pass through when changing the pond for seafood;

[0055] Inside the first live-keeping pool 112, the second live-keeping pool 113 and the third live-keeping pool 114, an internal rack 12 is provided; a sealing plate 13 is provided at the top of the internal rack 12; when normally cultivating seafood, the sealing plate 13 needs to be removed.

[0056] As an implementable mode, the drainage device 2 is respectively connected to the first live-keeping pool 112, the second live-keeping pool 113 and the third live-keeping pool 114 through water pipes for in-pool water circulation; the aeration device 3 is respectively connected to the first live-keeping pool 112, the second live-keeping pool 113 and the third live-keeping pool 114 through air pipes for oxygen supply; the refrigeration system 4 is respectively connected to the first live-keeping pool 112, the second live-keeping pool 113 and the third live-keeping pool 114 through metal pipes for in-pool temperature adjustment.

[0057] As Figure 3 and Figure 4 shown, as an implementable mode, the refrigeration system 4 includes an evaporator 41 and a condenser 42; the evaporator 41 is arranged inside the reservoir 111, and the condenser 42 is arranged on the first bottom plate 1121, the second bottom plate 1131 and the bottom of the third live-keeping pool 114; the condenser 42 is arranged at the bottom inside the pool, and cools down by staying away from the fish area, further reducing the harm to seafood; the reservoir 111 is used for storing standby water, and cold water or raw water cannot be directly introduced into the cultivation of fish seafood; it needs to be left standing until room temperature to prevent fish from dying; at the same time, the evaporator 41 is arranged inside the reservoir 111. Since heat is generated when the evaporator 41 refrigerates, it can be timely absorbed by the standby water inside the reservoir 111, and at the same time, the water inside the reservoir 111 can be heated or kept warm, so as to make full use of energy reasonably and be more energy-saving and environmentally friendly.

[0058] As Figures 5 - 10 shown, the internal rack 12 includes a front side plate 121 and a rear side plate 122; the front side plate 121 and the rear side plate 122 are connected by two middle side plates; the tops of the two middle side plates are higher than the front side plate 121 and the rear side plate 122, and a chute 125 is clamped inside the higher part, and the chute 125 matches the left and right sides of the sealing plate 13; when the sealing plate 13 cooperates with the chute 125, the top of the internal rack 12 can be sealed.

[0059] The lower end of the front side plate 121 is movably connected to the front side of the adsorption and purification device 123, and two connecting rods 124 are fixedly connected to the connection part between the lower end of the rear side plate 122 and the middle side plate; the lower ends of the connecting rods 124 are movably connected to the adsorption and purification device 123.

[0060] The width of the front side plate 121 is greater than the width of the rear side plate 122; this facilitates the adsorption and purification device 123 to be inserted into the bottom of the internal rack 12 from the side close to the front side plate 121 inside the internal rack 12 and connected to the front side plate 121.

[0061] As Figure 8 shown, as an implementable manner, a hanging hole 1211 is provided at the lower end of the front side plate 121, and a downward notch 1212 is provided on one side of the hanging hole 1211 close to the rear side plate 122; a hanging rod 1231 is provided on the front side of the adsorption and purification device 123, and the adsorption and purification device 123 is movably hinged to the lower end of the front side plate 121 by the hanging rod 1231 being inserted into the hanging hole 1211 from the notch 1212;

[0062] As Figure 9 shown, as an implementable manner, a hanging groove 1241 is provided on one side of the lower end of the connecting rod 124 close to the front side plate 121, and a guiding hook 1242 is provided below the hanging groove 1241; a magnet 1243 is provided above the hanging groove 1241; floating buoy suspensions 1232 are fixedly provided at two right-angle positions near the rear side of the top of the adsorption and purification device 123; the floating buoy suspensions 1232 are movably connected to the lower end of the connecting rod 124;

[0063] As Figure 11 shown, as an implementable manner, the floating buoy suspension 1232 includes a connecting block 1233, and the connecting block 1233 is fixedly connected to the adsorption and purification device 123; a connecting rod 1234 is rotatably connected to the inner end of the connecting block 1233, and a floating rod 1235 is provided at the upper end of the connecting rod 1234; the floating rod 1235 is made of a magnetic material and has strong buoyancy;

[0064] After the seafood is transferred to a new pool, in the new pool, the adsorption and purification device 123 is vertically inserted into the bottom of the built-in rack 12 from the side close to the front side plate 121 inside the built-in rack 12 and connected to the front side plate 121; the hanging rod 1231 is inserted into the hanging hole 1211 from the notch 1212 and movably hinged to the lower end of the front side plate 121; during this period, the fish school is blocked in the new pool. Since the floating rod 1235 has a certain buoyancy, when the floating rod 1235 moves upward, it can drive the adsorption and purification device 123 to turn upward with the hanging hole 1211 as the rotation center; at the same time, the adsorption and purification device 123 will automatically drive the fish school to swim upward; when the floating rod 1235 continues to move upward and touches the guiding hook 1242, at this time, the connecting rod 1234 will turn toward the side close to the front side plate 121. When the floating rod 1235 crosses the top of the guiding hook 1242, the connecting rod 1234 is vertical again, so that the floating rod 1235 is directly above the hanging groove 1241; at the same time, since the floating rod 1235 is made of a magnetic material, it will be adsorbed by the magnet 1243 at this time; in this way, when the seafood in the pool is transferred to a new pool later, or when the built-in rack 12 is lifted from the pool, the adsorption and purification device 123 is fixed below the connecting rod 124 and the front side plate 121;

[0065] Example 1: A method for non-contact pool changing of seafood (changing the pool from bottom to top):

[0066] Take the example of transferring the fish in the second preservation pond 113 to the first preservation pond 112;

[0067] Step 1: As Figure 7 shown, first drain the water in the first preservation pond 112 through the drainage device 2, and remove the adsorption and purification device 123 on the internal built-in rack 12;

[0068] Step 2: As Figure 12 shown, seal the internal built-in rack 12 in the second preservation pond 113 with the sealing plate 13; at this time, the second preservation pond 113 is filled with water, and both the second channel 1132 and the first channel 1122 are sealed by the connecting rod 124 on the internal built-in rack 12 in the third preservation pond 114 and the second preservation pond 113;

[0069] Step 3: Start the drainage device 2 to pass water into the second preservation pond 113 (the water comes from the inside of the reservoir 111); therefore, as the amount of water passing through increases, the pressure inside the second preservation pond 113 increases at this time, and the built-in rack 12 will move upward. Since the fish are placed inside the built-in rack 12, the adsorption and purification device 123 will drive the fish upward; when the first channel 1122 is opened, the water will flow into the first preservation pond 112. At this time, the first preservation pond 112 and the second preservation pond 113 temporarily form a communicating vessel; when continuing to pass water, since the top of the second preservation pond 113 is sealed by the sealing plate 13, the water level inside the second preservation pond 113 will tend to be level with the inside of the first preservation pond 112 at this time. In this way, the built-in rack 12 inside the second preservation pond 113 will continue to rise until the first channel 1122 is completely opened; at this time, the fish will enter the first preservation pond 112 through the first channel 1122;

[0070] Step 4: As Figure 13 shown, to ensure that more water enters the first preservation pond 112, start the aeration device 3 to pass gas into the bottom of the second preservation pond 113 at this time. The bubbles will move vertically upward due to their own buoyancy and burst at the top of the second preservation pond 113; in this way, a cavity will be formed inside the top of the second preservation pond 113, that is, inside the built-in rack 12; at the same time, the original water inside the second preservation pond 113 will flow into the first preservation pond 112. The fish will enter the first preservation pond 112 under the action of the water flow. At the same time, the more gas is passed into the second preservation pond 113, the less water there is at the top of the adsorption and purification device 123 at this time, which will force the fish to enter the first preservation pond 112;

[0071] To accelerate the entry of the fish into the first preservation pond 112, one can also manually hold the handle at the top of the sealing plate 13 and pull the built-in rack 12 up and down back and forth, and drive the fish quickly by moving the adsorption and purification device 123 at the bottom up and down;

[0072] Step 5: As Figure 14As shown, when the fish school completely enters the interior of the first live-holding pond 112,

[0073] In the first live-holding pond 112, insert the adsorption and purification device 123 vertically into the bottom of the built-in rack 12 from the side close to the front side plate 121 inside the built-in rack 12, and snap the hanging rod 1231 into the hanging hole 1211 through the notch 1212 and be movably hinged to the lower end of the front side plate 121; during this period, intercept the fish school in the new pond;

[0074] Step Six: As Figure 15 shown, since the floating rod 1235 has a certain buoyancy, when the floating rod 1235 moves upward, it can drive the adsorption and purification device 123 to turn upward with the hanging hole 1211 as the rotation center; at the same time, the adsorption and purification device 123 will automatically drive the fish school to swim upward; when the floating rod 1235 continues to move upward and touches the guiding hook 1242, at this time the connecting rod 1234 will turn towards the side close to the front side plate 121, and when the floating rod 1235 crosses the top of the guiding hook 1242, the connecting rod 1234 becomes vertical again, so that the floating rod 1235 is directly above the hanging groove 1241; at the same time, since the floating rod 1235 is made of magnetic material, it will be adsorbed and locked by the magnet 1243 at this time; in this way, when changing the pond for the seafood in the pond later, or when lifting the built-in rack 12 out of the pond, the adsorption and purification device 123 will be fixed below the connecting rod 124 and the front side plate 121;

[0075] Step Seven: As Figure 16 shown, displace the built-in rack 12 in the second live-holding pond 113 downward to block the first channel 1122; empty the water inside the second live-holding pond 113 through the drainage device 2;

[0076] This realizes the switching of the fish school between ponds from bottom to top in the present invention; by lifting the water in the original live-holding pond, the swimming range of the fish school is expanded, and then by adding gas to make the water in the original live-holding pond drop, the fish school is forced to swim towards the live-holding pond with more water; in this way, through the natural flow of the seafood fish, the damage to the fish school caused by manual pond changing is avoided; the survival rate of the seafood is greatly improved;

[0077] Embodiment 1: Seafood non-contact pond-changing method two (switching ponds from top to bottom):

[0078] Taking the conversion of fish in the first live-holding pond 112 to the second live-holding pond 113 as an example;

[0079] Step One: First, remove the adsorption and purification device 123 inside the first live-holding pond 112; the second live-holding pond 113 is not filled with water;

[0080] Step Two: Install the sealing plate 13 on the top of the built-in rack 12 inside the second live-holding pond 113;

[0081] Step 4: Hold the handle at the top of the portable sealing plate 13 to open the first channel 1122, so that the water inside the first live-holding pool 112 will flow downward into the second live-holding pool 113. At the same time, the fish school will also enter the second live-holding pool 113;

[0082] Step 5: When the fish school has completely entered the second live-holding pool 113, move the built-in rack 12 inside the second live-holding pool 113 downward to block the first channel 1122 and introduce an appropriate amount of water into the second live-holding pool 113;

[0083] This realizes the switching of the fish school between pools from top to bottom in the present invention; the original water automatically flows to the new live-holding pool by gravity, and the seafood fish flow by themselves, avoiding damage to the fish school caused by manual pool changing; greatly improving the survival rate of seafood;

2. The vertical live-keeping and farming device for seafood according to claim 1, wherein: The refrigeration system includes an evaporator and a condenser; the evaporator is arranged inside the water storage pool, and the condenser is arranged on the first bottom plate, the second bottom plate, and the bottom of the third live-holding pool.

3. The seafood changing pool method of the vertical live-holding aquaculture device for seafood according to any one of claims 1-2, characterized in that: Step 1: First, drain the water in the first live-holding pool through the drainage device, and remove the adsorption and purification device on the built-in rack inside; Step 2: Seal the built-in rack inside the second live storage tank with a sealing plate; at this time, the second live storage tank is filled with water, and both the second channel and the first channel are sealed by the connecting rods on the built-in racks inside the third and second live storage tanks; Step 3: Start the drainage device to let water flow into the second live storage tank; thus, as the water flow increases, the pressure inside the second live storage tank increases at this time, and the built-in rack will move upward. Since the fish school is placed inside the built-in rack, the adsorption and purification device will drive the fish school upward; when the first channel is opened, the water will flow into the first live storage tank. At this time, the first and second live storage tanks temporarily form a communicating vessel; when the water continues to flow, since the top of the second live storage tank is sealed by the sealing plate, the water level inside the second live storage tank will tend to be level with that inside the first live storage tank. In this way, the built-in rack inside the second live storage tank will continue to rise until the first channel is completely opened; at this time, the fish school will enter the first live storage tank through the first channel; Step 4: To ensure that more water enters the first live storage tank, start the aeration device to introduce gas into the bottom of the second live storage tank at this time. The bubbles will move vertically upward due to their own buoyancy and burst at the top of the second live storage tank; in this way, a cavity will be formed inside the top of the second live storage tank, that is, inside the built-in rack; at the same time, the original water inside the second live storage tank will flow into the first live storage tank, and the fish school will enter the first live storage tank under the action of the water flow. At the same time, the more gas is introduced into the second live storage tank, the less water there is at the top of the adsorption and purification device. In this way, the fish school will be forced to enter the first live storage tank; Step 5: When the fish school completely enters the first live storage tank, insert the adsorption and purification device vertically into the bottom of the built-in rack from the side close to the front side plate inside the built-in rack in the first live storage tank, and snap the hanging rod into the hanging hole from the notch to be movably hinged to the lower end of the front side plate; Step 6: Since the floating rod has a certain buoyancy, when the floating rod moves upward, it can drive the adsorption and purification device to turn upward with the hanging hole as the rotation center; at the same time, the adsorption and purification device will automatically drive the fish school to swim upward; when the floating rod continues to move upward and touches the guiding hook, at this time, the connecting rod will turn toward the side close to the front side plate. When the floating rod crosses the top of the guiding hook, the connecting rod will be vertical again, so that the floating rod is directly above the hanging groove; at the same time, since the floating rod is made of magnetic material, it will be adsorbed and locked by the magnet at this time; in this way, when converting the seafood in the pool later, or when lifting the built-in rack out of the pool, the adsorption and purification device will be fixed below the connecting rod and the front side plate; Step 7: Move the built-in rack inside the second live storage tank downward to block the first channel; empty the water inside the second live storage tank through the drainage device.
