[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] In the description of the present invention, "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] The fishery breeding system is a device used for artificial breeding of fish and other aquatic products. The existing fishery breeding system mainly includes breeding ponds and water purification components. The water discharged from the breeding pond is filtered, nitrified and disinfected by the water purification component, and then transported back to the breeding pond through the water circulation pipe to achieve water recycling.

[0044] However, the depth of the aquaculture ponds in existing fishery aquaculture systems is generally 1 to 2 meters, which is only suitable for aquatic products that live in shallow waters. It cannot meet the growth needs of aquatic products that live in deep waters with greater environmental pressure, such as deep-sea fish. In addition, since the top of the aquaculture pond is open, not only is the aquatic product easily affected by the external environment, such as the external temperature, but also when the water in the aquaculture pond is oxygenated, most of the oxygen will quickly flow from the top of the aquaculture pond to the atmosphere, resulting in low oxygen dissolution efficiency, more times of oxygen replenishment, and high energy consumption.

[0045] To this end, the present invention provides a breeding tank and a closed fishery breeding system, which can effectively solve the above problems.

[0046] Reference below Figures 1 to 9 A breeding tank and a closed fish breeding system according to embodiments of the present invention are described.

[0047] According to the breeding tank of the first embodiment of the present invention, Figures 1 to 9 As shown, it includes a tank body 100, a feeding component 200, an air supply pipe 300 and an oxygen supply component 400.

[0048] Among them, the tank body 100 is a closed structure, and a breeding chamber 101 is formed in the tank body 100. The breeding chamber 101 is used to breed aquatic products such as fish. The aquatic products can be fish or other suitable types, such as shrimps. The tank body 100 is provided with a water inlet pipe 102. The water inlet pipe 102 can be one or more. The water inlet pipe 102 is connected to the breeding chamber 101 for inputting water into the breeding chamber 101.

[0049] The feeding assembly 200 is disposed on the tank body 100 and is used to feed feed for the growth of aquatic products into the culture cavity 101 .

[0050] The gas pipe 300 is provided on the tank body 100 and connected to the breeding chamber 101. The gas pipe 300 can be connected to a gas generator such as an air compressor. The gas generator transmits gas to the breeding chamber 101 through the gas pipe 300 to adjust the pressure in the breeding chamber 101. The gas provided by the gas generator can be air, nitrogen and other gases that are difficult to dissolve in water.

[0051] The oxygen supply component 400 is connected to the tank body 100 to supply oxygen to the culture chamber 101. For example, the oxygen supply component 400 can be connected to an oxygen generator, which inputs oxygen into the oxygen supply component 400, and then transports oxygen to the culture chamber 101 through the oxygen supply component 400 and dissolves with the water in the culture chamber 101.

[0052] In the present invention, water for the fish and other aquatic products is transported into the culture chamber 101 of the tank body 100 through the water inlet pipe 102, and food is fed into the culture chamber 101 through the feeding component 200, and oxygen is supplied into the culture chamber 101 through the oxygen supply component 400. Since the tank body 100 of the present invention is a closed structure, it can not only reduce the influence of the external environment on the aquatic products, but also prevent the oxygen from directly flowing into the atmosphere when supplying oxygen into the culture chamber 101 through the oxygen supply component 400, so that the oxygen and water have a better dissolution effect, higher oxygen dissolution efficiency, fewer times of replenishment of dissolved oxygen, and lower energy consumption. In addition, by transporting gas into the culture chamber 101 through the gas pipe 300, the air pressure at the top of the culture chamber 101 can be adjusted, and the water pressure of the water in the culture chamber 101 is affected by the air pressure environment, and the water pressure of the water in the culture chamber 101 can be indirectly adjusted, so that the water pressure environment at different depths can be simulated, and the pressure requirements of aquatic products grown under different environmental pressures can be met.

[0053] It should be noted that the tank body 100 may also be provided with a seedling opening 106, which may be provided with an openable and closable cover, and the seedling opening 106 is used to put in fish fry or other aquatic product seedlings. The tank body 100 may also be provided with an observation window 107 to facilitate observation of the growth status of aquatic products and the status of water in the culture chamber 101.

[0054] If a feeding port and a cover for opening and closing the feeding port are directly provided on the tank body 100, when feeding into the culture chamber 101 and opening the cover, the culture chamber 101 will be connected to the external environment, causing the air pressure in the culture chamber 101 to drop rapidly to atmospheric pressure, which will in turn cause the water pressure in the culture chamber 101 to drop rapidly, thereby affecting the growth of aquatic products in the culture chamber 101 and even causing the death of aquatic products in the culture chamber 101. Figure 2As shown, in some embodiments of the present invention, the feeding assembly 200 includes a feeding cylinder 201 and a pressure regulating mechanism. The feeding cylinder 201 is disposed at the top of the tank body 100 and communicates with the culture chamber 101. The top of the feeding cylinder 201 is provided with a first valve 202, and the bottom of the feeding cylinder 201 is provided with a second valve 203. The feeding cylinder 201 forms a storage chamber 204 between the first valve 202 and the second valve 203. The pressure regulating mechanism is disposed in the feeding cylinder 201 to regulate the air pressure in the storage chamber 204. For example, the top and bottom of the feeding cylinder 201 can be penetrated, the first valve 202 is used to open and close the top of the feeding cylinder 201, the second valve 203 is used to open and close the bottom of the feeding cylinder 201, and the pressure regulating mechanism is used to regulate the air pressure in the storage chamber 204, and can at least regulate the air pressure in the storage chamber 204 to be close to the atmospheric pressure, and to be close to the air pressure in the culture chamber 101.

[0055] In the present embodiment, when it is necessary to feed the culture chamber 101, the air pressure in the storage chamber 204 can be adjusted to be close to the atmospheric pressure through the pressure regulating mechanism. The air pressures on both sides of the first valve 202 are similar, so the first valve 202 can be easily opened. After the feed is poured into the storage chamber 204, the first valve 202 is closed, and then the air pressure in the storage chamber 204 is adjusted to be close to the air pressure in the culture chamber 101 through the pressure regulating mechanism. The air pressures on both sides of the second valve 203 are similar, so the second valve 203 can be easily opened. The feed in the storage chamber 204 can also be easily dropped into the culture chamber 101. Before opening the second valve 203, since the air pressure in the storage chamber 204 is close to the air pressure in the culture chamber 101, the air pressure in the culture chamber 101 will not be affected, thereby not affecting the growth of aquatic products in the culture chamber 101, and not causing the death of aquatic products in the culture chamber 101. The use is more convenient and the practicability is better.

[0056] refer to Figure 2 As shown, in some embodiments of the present invention, the pressure regulating mechanism includes a first regulating tube 205 and a second regulating tube 207, one end of the first regulating tube 205 is connected to the feeding cylinder 201 and connected to the storage chamber 204, and the other end is used to connect to the atmosphere, the first regulating tube 205 is provided with a third valve 206, one end of the second regulating tube 207 is connected to the feeding cylinder 201 and connected to the storage chamber 204, and the other end is connected to the tank body 100 and connected to the breeding chamber 101, and the second regulating tube 207 is provided with a fourth valve 208.

[0057] In this embodiment, the third valve 206 is opened, and the storage chamber 204 can be connected to the external atmospheric environment through the first regulating tube 205, so that the air pressure in the storage chamber 204 can be quickly adjusted to close to the atmospheric pressure. The fourth valve 208 is opened, and the storage chamber 204 can be connected to the breeding chamber 101 through the second regulating tube 207, so that the air pressure in the storage chamber 204 can be quickly adjusted to close to the air pressure in the breeding chamber 101. It not only has a simple structure and convenient operation, but also has high adjustment accuracy and better practicality.

[0058] It should be noted that the pressure regulating mechanism may also be other structures, for example, it may also be an air pump, which can also adjust the air pressure of the storage chamber 204 by pumping or releasing air from the storage chamber 204. When the structure of the pressure regulating mechanism is different, the structure of the feeding assembly 200 is also different accordingly, which will not be described in detail here.

[0059] In some embodiments of the present invention, the first valve 202, the second valve 203, the third valve 206 and the fourth valve 208 can all be solenoid valves, and a plurality of visual sensors can be provided in the breeding chamber 101. The first valve 202, the second valve 203, the third valve 206, the fourth valve 208 and the visual sensor can all be connected to an external control system. The control system has a database and stores an algorithm program. The database stores a large amount of data information, including data information such as the activity status of different aquatic products at different growth stages, the required feeding frequency and the required amount of feed. The visual sensor can monitor the activity status of the aquatic products in real time and send the activity status information of the aquatic products to the database. The control system compares the information sent by the visual sensor with the data information in the database through the algorithm program to determine whether the aquatic products are in a hungry state or a full state, and controls the opening and closing of the first valve 202, the second valve 203, the third valve 206 and the fourth valve 208 according to the judgment result, thereby realizing precise feeding, which not only makes breeding more convenient, but also has higher breeding efficiency and better effect, and can reduce feed waste and lower economic cost.

[0060] It should be noted that, in some other embodiments of the present invention, the first valve 202, the second valve 203, the third valve 206 and the fourth valve 208 may also be manual valves.

[0061] refer to Figure 1 and Figure 7As shown, in some embodiments of the present invention, the breeding tank also includes a sewage discharge component 500, and the sewage discharge component 500 includes a sewage discharge pipe 501, which is arranged in the middle position of the bottom end of the tank body 100 and connected to the breeding chamber 101; two water inlet pipes 102 are provided, and the two water inlet pipes 102 are respectively connected to the two ends of the length direction of the tank body 100, and along the projection of the length direction of the tank body 100, the connection positions of the two water inlet pipes 102 and the tank body 100 are respectively located on the opposite sides of the tank body 100. When the two water inlet pipes 102 supply water at the same time, the water in the breeding chamber 101 forms a vortex under the impetus of the water discharged from the two water inlet pipes 102.

[0062] For example, the sewage pipe 501 is used to discharge water mixed with excrement of aquatic products and feed residues. The two ends of the length direction of the tank body 100 can be the first end and the second end respectively. One water inlet pipe 102 is arranged at the first end, and the other water inlet pipe 102 is arranged at the second end. In addition, along the projection of the length direction of the tank body 100, the water outlet positions of the two water inlet pipes 102 can be respectively located on both sides of the width direction of the tank body 100, and the water outlet direction of the water inlet pipe 102 can be the length direction of the tank body 100, that is, the water outlet direction of one water inlet pipe 102 points from the first end to the second end, and the water outlet direction of the other water inlet pipe 102 points from the second end to the first end.

[0063] In this way, when the two water inlet pipes 102 supply water at the same time, the water in the culture chamber 101 can form a vortex under the impetus of the water discharged from the two water inlet pipes 102, and the center of the vortex is close to the middle of the tank body 100. In this way, the water forming the vortex can drive the excrement and feed residue in the culture chamber 101 to gradually move to the vicinity of the sewage pipe 501 in the middle of the tank body 100, thereby facilitating the rapid and thorough discharge of the excrement and feed residue through the sewage pipe 501, which is more conducive to the growth of aquatic products. In addition, the water flow also makes the dissolved oxygen effect better.

[0064] The water discharged from the sewage pipe 501 is filtered, nitrified, sterilized and treated in other ways before flowing back into the aquaculture chamber 101 of the tank 100 through the water inlet pipe 102. However, during the long-term aquaculture process, a certain amount of water will be absorbed by the aquatic products. In addition, some water may be wasted in other ways. Figure 1 and Figure 7 As shown, in some embodiments of the present invention, both ends of the tank body 100 in the length direction are respectively connected with water supply pipes 103, and the water supply pipes 103 can regularly replenish the reduced water in the culture chamber 101, so that the water volume in the culture chamber 101 meets the requirements for aquatic product culture. Moreover, the water inlet pipe 102 and the water supply pipe 103 at the same end of the tank body 100 are respectively located on opposite sides of the tank body 100. When the two water supply pipes 103 supply water at the same time, the water in the culture chamber 101 forms a vortex under the impetus of the water discharged from the two water supply pipes 103.

[0065] For example, one of the water supply pipes 103 is arranged at the first end, and the other water supply pipe 103 is arranged at the second end, and along the projection of the length direction of the tank body 100, the water outlet positions of the two water supply pipes 103 can be respectively located on both sides of the width direction of the tank body 100, and the water outlet direction of the water supply pipe 103 can be the length direction of the tank body 100, that is, the water outlet direction of one of the water supply pipes 103 points from the first end to the second end, and the water outlet direction of the other water supply pipe 103 points from the second end to the first end. When the two water supply pipes 103 supply water at the same time, the water in the culture chamber 101 forms a vortex under the impetus of the water discharged from the two water supply pipes 103, and the center position of the vortex is close to the middle position of the tank body 100. In this way, the water forming the vortex can drive the excrement and feed residues in the culture chamber 101 to gradually move to the vicinity of the sewage pipe 501 in the middle of the tank body 100, thereby facilitating the rapid and thorough discharge of the excrement and feed residues through the sewage pipe 501, which is more conducive to the growth of aquatic products. In addition, water flow also makes the dissolved oxygen effect better.

[0066] refer to Figure 6 As shown, in some embodiments of the present invention, the breeding tank also includes a sewage discharge component 500, which includes a sewage discharge pipe 501, a sewage collecting cylinder 502 and a filter tube 504. The sewage collecting cylinder 502 is arranged at the bottom end of the tank body 100, and the top end of the sewage collecting cylinder 502 is connected to the breeding chamber 101 and is provided with a filter screen 503. The sewage discharge pipe 501 is connected to the sewage collecting cylinder 502, and the filter tube 504 can be vertically arranged in the breeding chamber 101. The top end of the filter tube 504 extends to the top end of the breeding chamber 101 and is closed. The bottom end of the filter tube 504 is connected to the sewage collecting cylinder 502, and the top end of the side wall of the filter tube 504 is provided with a plurality of first filter holes 505, and the bottom end of the side wall of the filter tube 504 is provided with a plurality of second filter holes 506.

[0067] For example, the top of the dirt collection cylinder 502 can be provided through, the filter screen 503 is provided at the top of the dirt collection cylinder 502, the aperture of the filter screen 503 is larger than the size of the excrement and feed residue of the aquatic product, but smaller than the size of the aquatic product. The bottom end of the filter tube 504 can be provided through and extend into the dirt collection cylinder 502, the filter screen 503 can surround the circumference of the filter tube 504 and be connected to the outer wall of the filter tube 504, the aperture of the first filter hole 505 and the second filter hole 506 is larger than the size of the excrement and feed residue of the aquatic product, but smaller than the size of the aquatic product.

[0068] In this embodiment, during the breeding process, the excrement and feed residues of aquatic products can enter the sewage collection cylinder 502 through the filter holes of the filter screen 503, and then be discharged through the sewage pipe 501, which has a better sewage discharge effect and is more conducive to the growth of aquatic products. The filter screen 503 can prevent the aquatic products from being discharged through the sewage pipe 501 and causing economic losses.
