Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a liquid oxygen device for sturgeon farming that can self-regulate according to weather conditions. Background Technology

[0002] Aquaculture is the practice of humans using aquatic waters for aquaculture, according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, and employing aquaculture technologies and facilities to raise aquatic economic animals and plants. Sturgeon farming is a type of aquaculture. During sturgeon farming, the water temperature needs to be controlled within a certain range, generally between 15 and 26 degrees Celsius. This temperature range is suitable for sturgeon growth, and liquid oxygen devices are also required to ensure the oxygen content in the water.

[0003] Existing liquid oxygenation systems for sturgeon farming have the following two drawbacks:

[0004] 1. After the liquid oxygen device is installed, the output end position and output angle are relatively fixed. During the process of outputting liquid oxygen, the oxygen content in the water will be unevenly distributed, which will affect the growth of sturgeon and the quality of aquaculture.

[0005] 2. During sturgeon farming, it is necessary to maintain the oxygen content in the water at a suitable temperature. However, when the liquid oxygen tank in the liquid oxygen device is replaced, oxygen supply is temporarily interrupted. During this period, the oxygen content in the water decreases, which in turn affects the farming quality.

[0006] Therefore, this invention proposes a liquid oxygen device for sturgeon farming that can self-regulate according to the weather, in order to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a liquid oxygen device for sturgeon farming that can self-regulate according to weather conditions, effectively solving the technical problems of uneven oxygen distribution in water and the inability to regulate oxygen levels when water temperature drops during sturgeon farming.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention discloses a liquid oxygen device for sturgeon farming that can self-adjust according to weather conditions. It includes a rearing tank and a heating tank located on the right side of the rearing tank for temporary storage and heating of water.

[0015] Preferably, the connecting assembly includes connecting columns, rubber plugs, movable frames, vertical grooves, springs, and top blocks. Connecting columns are symmetrically fixedly connected to the bottom lower surface of the mixing tank. Movable frames are slidably connected to the ends of the surfaces of the multiple connecting columns away from the mixing tank. The movable frames are slidably connected to the inner wall of the breeding tank. The mixing columns are rotatably connected to the movable frames. Rubber plugs are fixedly connected to the top of the movable frames. Top blocks are fixedly connected to the ends of the multiple connecting columns away from the mixing tank. Vertical grooves are symmetrically formed on the surface of the movable frames. The top blocks are slidably connected to the vertical grooves. Springs are fixedly connected to the surface of the top blocks away from the connecting columns.

[0016] Preferably, the inner wall of the breeding box is symmetrically provided with arc-shaped grooves, both of which are slidably connected to the movable frame. Friction pads are fixedly connected to both ends of the surface of the movable frame, and the friction pads are installed in conjunction with the arc-shaped grooves.

[0017] Preferably, the drainage assembly includes a protruding column, an auger, a lifting block, an arc-shaped protrusion, and a through hole. The end of the stirring column away from the top of the breeding tank is fixedly connected to the protruding column, and the lifting block is fixedly connected to the surface of the protruding column. An arc-shaped protrusion is installed at the water outlet of the breeding tank, and through holes are symmetrically opened along the center on the outer side of the arc-shaped protrusion. The lifting block is slidably connected to the arc-shaped protrusion.

[0018] Preferably, the adjustment assembly includes an adjustment plate, a circular groove, a cylinder, a spiral groove, a protrusion, a worm gear, and a worm wheel. The adjustment plates are symmetrically fixed to the outer side of the mixing tank. The adjustment plates are slidably connected to the inner wall of the breeding tank. Circular grooves are formed on the end faces of both adjustment plates away from the mixing tank. A cylinder is fitted onto the surface of the circular groove. A spiral groove is formed on the outer side of the cylinder. A protrusion is fitted onto one end of the spiral groove. The protrusion is mounted on the surface of the circular groove.

The ends of both worm gears away from the cylinder are rotatably connected to the breeding tank. A worm wheel is meshed onto the outer side of the worm gear. The entire adjustment assembly moves with the mixing tank, thereby adjusting the output position and angle of the nozzle while simultaneously mixing and draining the water in the mixing tank.

[0019] Preferably, the inner wall of the breeding box is symmetrically provided with mounting grooves, and the adjusting plate is slidably connected to the mounting grooves.

[0020] Preferably, the oxygen supply assembly includes a liquid oxygen storage mechanism, an oxygen delivery pipe, and a nozzle. An oxygen delivery pipe is installed on the surface of the worm gear.

[0021] Compared with known public technologies, the technical solution provided by this invention has the following beneficial effects:

[0022] 1. This invention uses a conveying mechanism to transport water, creating a water circulation system between the breeding tank and the heating tank. Compared to existing technologies, by continuously adjusting the position and angle of the oxygen supply pipe and nozzle, the spray angle and position of the liquid oxygen are changed. Each time the water in the mixing tank is stirred and discharged, the position and angle of the liquid oxygen pipe and nozzle are adjusted simultaneously, preventing oxygen supply from being concentrated on one side and ensuring that oxygen can be supplied from multiple different positions and angles within the breeding tank. This ensures that the oxygen content in the water within the breeding tank is evenly distributed, thereby guaranteeing the quality of sturgeon farming.

[0023] 2. In this invention, the first motor drives the transmission column to rotate, and the stirring column rotates along with the transmission column. The stirring blades can stir the water placed in the stirring tank. Stirring the water can improve the mixing and circulation of the water, promote the exchange between the gas and water, thereby increasing the solubility of oxygen. Stirring can fully mix the oxygen on the surface of the water with the oxygen at the bottom, so that the oxygen in the water is evenly distributed, thereby achieving the purpose of oxygenation. When the liquid oxygen tank is replaced, liquid oxygen cannot be provided temporarily. The water transported from the heating tank into the breeding tank can ensure sufficient oxygen content, avoiding the impact of reduced oxygen content on the quality of sturgeon breeding. When the liquid oxygen tank is not replaced, it can further ensure sufficient oxygen content in the water in the breeding tank, ensuring the quality of sturgeon breeding.

[0024] 3. The conveying mechanism continuously transports water from the heating box to the breeding box, and discharges it from the mixing box to the bottom of the breeding box, constantly rinsing the bottom and upper surface of the breeding box to prevent excess feed and sturgeon excrement from remaining at the bottom of the breeding box. This allows for rapid drainage of water from the breeding box, enabling quick water exchange. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] The present invention will be further described below with reference to embodiments.

[0046] Embodiments of the present invention

[0047] Please see Figure 1 , Figure 2 , Figure 9 and Figure 12 A liquid oxygen device for sturgeon farming that can be self-adjusted according to the weather includes a breeding tank 1 and a heating tank 11 located on the right side of the breeding tank 1 for temporary storage and heating of water. The top surface of the breeding tank 1 has a top round hole, and the bottom surface of the breeding tank 1 has a water outlet and a bottom round hole. The top round hole is used to place sturgeon in the breeding tank 1, the bottom round hole is used for the sturgeon to leave the breeding tank 1, the water outlet is used for drainage, and a water outlet valve can be installed on the surface of the bottom round hole.

[0048] The top of the heating box 11 is equipped with a conveying mechanism 12 for conveying water from the heating box 11 to the breeding box 1. A connecting pipe 13 is fixedly connected between the heating box 11 and the breeding box 1. A check valve 14 is installed on the surface of the connecting pipe 13. The check valve 14 is a type of one-way valve. When the water level in the breeding box 1 rises, water will flow into the heating box 11 through the connecting pipe 13 and the check valve 14, thereby ensuring that the water level in the breeding box 1 can be controlled within a certain range and avoiding the impact of rising water level due to rainy weather. Furthermore, when the water is circulated between the breeding box 1 and the heating box 11, it is ensured that the water in the breeding box 1 can be discharged into the heating box 11.

[0049] The breeding tank 1 is equipped with a stirring mechanism 2 for increasing the oxygen content in the water supplied from the heating tank 11, and the outside of the breeding tank 1 is equipped with a liquid oxygen mechanism 3 for increasing the oxygen content in the water in the heating tank 11.

[0050] The stirring mechanism 2 includes a stirring component 21 and a centrifugal component 22 that can adjust the up and down movement of the stirring component 21, a connecting component 23 for automatically draining water from the stirring component 21, and a drainage component 24 for quickly draining water from the breeding tank 1.

[0051] The liquid oxygen mechanism 3 includes an oxygen supply component 31 for temporary storage and transportation of liquid oxygen, and an adjustment component 32 for adjusting the angle of the oxygen supply component 31.

[0052] It should be noted that the conveying mechanism 12 includes a water pump and a conveying pipeline, which are existing mature technologies and will not be described in detail here.

[0053] Please refer to the specific implementation process. Figure 2 , Figure 3 , Figure 10 and Figure 11 The mixing assembly 21 includes a motor housing 211, a first motor 212, a transmission column 213, a mixing column 214, mixing blades 215, and a mixing box 216. The motor housing 211 is fixedly connected to the top surface of the breeding tank 1. The first motor 212 is installed inside the motor housing 211. The output end of the first motor 212 is fixedly connected to the transmission column 213. The mixing column 214 is slidably inserted into the transmission column 213. Mixing blades 215 are symmetrically and equidistantly fixedly connected to the surface of the mixing column 214. The mixing box 216 is located below the motor housing 211 inside the breeding tank 1. The first motor 212 drives the transmission column 213 to rotate. The transmission column 213 and the mixing column 214 are slidably inserted into each other. The mixing column 214 is close to the breeding tank. One end of the top of the tank 1 is hexagonal prism. The end face of the transmission column 213 away from the first motor 212 has a groove. The stirring column 214 is slidably inserted into the groove to ensure that the rotation of the transmission column 213 can stably drive the stirring column 214 to rotate. The stirring column 214 can slide relative to the groove within a certain range. The stirring blades 215 rotate with the stirring column 214. Multiple stirring blades 215 stir the water in the stirring tank 216 to increase the oxygen content in the water. The water conveyed by the conveying mechanism 12 is heated by the heating box 11 and then mixed with the water in the breeding tank 1. This can ensure the temperature of the water in the breeding tank 1 and the water temperature during sturgeon breeding, increase the oxygen content in the water, and avoid affecting the breeding effect.

[0054] Please see Figure 7 , Figure 11 and Figure 13The centrifugal assembly 22 includes a rotating column 221, a mounting base 222, a sphere 223, a first connecting block 224, a second connecting block 225, and a rotating block 226. The mounting base 222 is symmetrically and fixedly connected to the outer side of the transmission column 213. The rotating column 221 is hinged to the surface of the mounting base 222. The sphere 223 is fixedly connected to the end of the rotating column 221 away from the mounting base 222. The first connecting block 224 is slidably connected to the surface of the rotating column 221. The second connecting block 225 is symmetrically and rotatably connected to the surface of the mixing tank 216. The rotating block 226 is rotatably connected between the first connecting block 224 and the second connecting block 225. The surfaces of both the first connecting block 224 and the second connecting block 225 are... The T-shaped structure consists of two rotating columns 221 and a ball 223 that rotate along with the transmission column 213. As the ball 223 rotates, the angle between the rotating column 221 and the transmission column 213 increases under the action of centrifugal force. During this process, the first connecting block 224 slides relative to the slide groove 227, and the two second connecting blocks 225 rotate relative to the annular groove 228. The connecting blocks serve a connecting function. As the rotating column 221 rotates, the mixing tank 216 moves towards the top of the breeding tank 1. While stirring the water in the mixing tank 216, the mixing tank 216 gradually separates from the rubber stopper 232, allowing the water in the mixing tank 216 to enter the bottom of the breeding tank 1.

[0055] Please see Figure 7 and Figure 13 Between the rotating column 221 and the mixing box 216, the surfaces of the two rotating columns 221 near the mixing box 216 are provided with sliding grooves 227. The first connecting block 224 is slidably connected to the sliding grooves 227. The surface of the mixing box 216 is provided with an annular groove 228. The two second connecting blocks 225 are rotatably connected to the annular grooves 228. The surfaces of the first connecting block 224 and the second connecting block 225 are T-shaped, which can play a good connecting role. When the angle between the rotating column 221 and the transmission column 213 changes, the first connecting block 224 can slide relative to the sliding groove 227. The rotating block 226 rotates relative to the first connecting block 224 and the second connecting block 225, which can adapt to the rotation adjustment of the rotating column 221. While the rotating column 221 rotates, it can drive the mixing box 216 to move towards the top of the breeding box 1.

[0056] Further, please refer to Figure 2 , Figure 3 and Figure 4The connecting assembly 23 includes connecting posts 231, rubber plugs 232, movable frames 233, vertical grooves 234, springs 235, and top blocks 236. Connecting posts 231 are symmetrically fixedly connected to the lower bottom surface of the mixing tank 216. Movable frames 233 are slidably connected to the ends of the connecting posts 231 away from the mixing tank 216. The movable frames 233 are slidably connected to the inner wall of the breeding tank 1. The mixing posts 214 are rotatably connected to the movable frames 233. Rubber plugs 232 are fixedly connected to the top of the movable frames 233. Top blocks 236 are fixedly connected to the ends of the connecting posts 231 away from the mixing tank 216. Vertical grooves 235 are symmetrically formed on the surface of the movable frames 233. 4. The top block 236 is slidably connected to the vertical groove 234. A spring 235 is fixedly connected to the surface of the top block 236 away from the connecting column 231. As the mixing box 216 moves towards the top of the breeding box 1, the rubber plug 232 gradually separates from the mixing box 216. After mixing for a period of time, the mixing box 216 automatically drains water. The connecting column 231 moves with the mixing box 216. The top block 236 and the vertical groove 234 slide relative to each other. The spring 235 is stretched. Since the movable frame 233 is installed in cooperation with the inner wall of the breeding box 1 through the arc block, the movable frame 233 is rotated and limited. This also limits the installation of the mixing box 216 and the movable frame 233.

[0057] Further, please refer to Figure 13 and Figure 11 The inner wall of the breeding box 1 is symmetrically provided with arc-shaped grooves 237. Both arc-shaped grooves 237 are slidably connected to the movable frame 233. Friction pads 238 are fixedly connected to both ends of the surface of the movable frame 233. The friction pads 238 are installed in conjunction with the arc-shaped grooves 237. The friction pads 238 can make close contact with the surface of the arc-shaped grooves 237. The friction between the friction pads 238 and the arc-shaped grooves 237 is used to make the movement of the mixing box 216 and the connecting column 231 drive the movement of the movable frame 233, thereby ensuring the stability of the lifting block 243 after position adjustment.

[0058] Further, please refer to Figure 13 , Figure 10 and Figure 14The drainage component 24 includes a protruding column 241, an auger 242, a lifting block 243, an arc-shaped protrusion 244, and through holes 245. The end of the stirring column 214 furthest from the top of the breeding tank 1 is fixedly connected to the protruding column 241. The lifting block 243 is fixedly connected to the surface of the protruding column 241. An arc-shaped protrusion 244 is installed at the outlet of the breeding tank 1. Through holes 245 are symmetrically opened along the center on the outer side of the arc-shaped protrusion 244. The lifting block 243 is slidably connected to the arc-shaped protrusion 244. Due to the friction between the friction pad 238 and the arc-shaped groove 237, when the stirring tank 216 moves towards the top of the breeding tank 1, the movable frame 233, stirring column 214, protruding column 241, and auger 242 do not move with the stirring tank 216. That is, the lifting block 243 can block the multiple through holes 245 opened on the surface of the arc-shaped protrusion 244. To prevent water leakage from the breeding tank 1, as the output power of the first motor 212 gradually increases, the mixing tank 216 will move further towards the top of the breeding tank 1 under the influence of centrifugal force, overcoming the friction between the friction pad 238 and the arc groove 237. At this time, the top block 236 is located at the end of the vertical groove 234 near the mixing tank 216. The movable frame 233 moves with the mixing tank 216. The lifting block 243 separates from the multiple through holes 245, no longer blocking the through holes 245, allowing drainage from the multiple through holes 245. The auger 242 rotates together with the protruding column 241 and the mixing column 214, facilitating the rapid discharge of water from the breeding tank 1. This can be used daily for rapid water changes in the breeding tank 1, preventing excessive accumulation of sturgeon excrement in the water, which could lead to the growth of bacteria and viruses and thus affect the quality of sturgeon farming.

[0059] Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8The adjusting assembly 32 includes an adjusting plate 321, a circular groove 322, a cylinder 323, a spiral groove 324, a protrusion 325, a worm gear 326, and a worm wheel 327. Adjusting plates 321 are symmetrically fixedly connected to the outer side of the mixing tank 216. The adjusting plates 321 are slidably connected to the inner wall of the breeding tank 1. Circular grooves 322 are formed on the ends of the two adjusting plates 321 away from the mixing tank 216. A cylinder 323 is fitted onto the surface of the circular groove 322. A spiral groove 324 is formed on the outer side of the cylinder 323. A protrusion 325 is fitted onto one end of the surface of the spiral groove 324. The protrusion 325 is mounted on the surface of the circular groove 322. A worm gear 326 is rotatably connected to the end of the cylinder 323 away from the adjusting plate 321 via a one-way bearing. The ends of the two worm gears 326 away from the cylinder 323 are rotatably connected to the breeding tank 1. A worm wheel 327 is meshed onto the outer side of the worm gear 326. The adjusting plates 321 move with the mixing tank 216. As the mixing tank 216 moves closer to the top of the aquaculture tank 1, the adjusting plate 321 and the cylinder 323 move relative to each other. The protrusion 325 is fixedly connected to the circular groove 322. The protrusion 325 moves with the adjusting plate 321, and the protrusion 325 also moves relative to the spiral groove 324, thereby driving the cylinder 323 to rotate. Due to the action of the one-way bearing, when the adjusting plate 321 moves closer to the top of the aquaculture tank 1 with the mixing tank 216, the rotation of the cylinder 323 can drive the worm gear 326 to rotate, which in turn drives the worm wheel 327 to rotate. The oxygen supply pipe 312 rotates with the rotation of the worm wheel 327, thereby changing the output position and output angle of the liquid oxygen. This prevents the oxygen content in the water in the aquaculture tank 1 from being concentrated on one side. The output angle and output position of the oxygen supply pipe 312 can be adjusted when stirring the heated water in the mixing tank 216 or when changing the water in the aquaculture tank 1.

[0060] Further, please refer to Figure 2 , Figure 3 and Figure 8 The inner wall of the breeding box 1 is symmetrically provided with mounting grooves 328. The adjusting plate 321 is slidably connected to the mounting grooves 328. The mounting grooves 328 serve as installation limits and can ensure the stability of the adjusting plate 321 when adjusting its position.

[0061] Further, please refer to Figure 2 , Figure 3 , Figure 1 and Figure 5The oxygen supply component 31 includes a liquid oxygen storage mechanism 311, an oxygen supply pipe 312, and a nozzle 313. The surface of the worm gear 327 is equipped with an oxygen supply pipe 312. Both oxygen supply pipes 312 are rotatably connected to the aquaculture tank 1. One end of the oxygen supply pipe 312 is rotatably connected to the liquid oxygen storage mechanism 311, and the other end of the oxygen supply pipe 312 is fixedly connected to the nozzle 313. The liquid oxygen is transported from the liquid oxygen storage mechanism 311 to the oxygen supply pipe 312 and sprayed out from the nozzle 313 into the aquaculture tank 1 to increase the oxygen content in the water in the aquaculture tank 1. The oxygen supply pipe 312 can rotate with the worm gear 327 to adjust the position and angle of the nozzle 313.

[0062] It should be noted that the liquid oxygen storage mechanism 311 includes a liquid oxygen tank and an oxygenation pump, which are existing mature technologies and will not be described in detail here. A controller can be installed on the surface of the breeding box 1. The water outlet valve, heating box 11, conveying mechanism 12, liquid oxygen storage mechanism 311 and first motor 212 are all electrically connected to the controller. The controller is precisely controlled by a computer or other control terminal, and the overall operation is controlled by the controller.

[0063] The complete working principle and steps of the above embodiments are as follows:

[0064] In a summer outdoor environment, initially, both the breeding tank 1 and the heating tank 11 contain water. The conveying mechanism 12 transports the unheated water from the heating tank 11 to the mixing tank 216. The first motor 212 drives the transmission column 213 to rotate, and the stirring column 214 rotates along with the transmission column 213. The stirring blades 215 stir the water in the mixing tank 216. Stirring the water improves mixing and circulation, promotes the exchange of gases between the water and the atmosphere, thereby increasing oxygen solubility. Stirring thoroughly mixes oxygen from the surface and bottom layers, ensuring a uniform distribution of oxygen in the water, thus increasing oxygen content. The first motor 212 continues to drive the transmission column 213 to rotate, and the stirring continues... After a period of time, due to centrifugal force, sphere 223 rotates along with rotating column 221 and moves towards the top of breeding tank 1. Due to the connection between first connecting block 224, second connecting block 225 and rotating block 226, mixing tank 216 also gradually moves towards the top of breeding tank 1. Rubber stopper 232 separates from mixing tank 216. At this time, movable frame 233 does not move, and water in mixing tank 216 is drained into the bottom of breeding tank 1. The water in breeding tank 1 is oxygenated by liquid oxygen storage mechanism 311, which sprays out from nozzle 313 through oxygen supply pipe 312. As the water circulation is formed between breeding tank 1 and heating tank 11, water placed in heating tank 11 is transported into the breeding tank through conveying mechanism 12. Inside tank 1, as the water level rises, water flows through connecting pipe 13 and check valve 14 into heating tank 11. Water from heating tank 11 into breeding tank 1 is first placed in mixing tank 216. The first motor 212 drives transmission column 213 to rotate, causing two rotating columns 221 and a ball 223 to rotate along with transmission column 213. The ball 223 moves towards the top of breeding tank 1, thus moving mixing tank 216. Adjusting plate 321 moves towards the top of breeding tank 1 along with mixing tank 216. Relative movement occurs between protrusion 325 and spiral groove 324, causing cylinder 323 to rotate. The rotation of cylinder 323 drives worm gear 326 to rotate, which in turn drives worm wheel 327 to rotate, thus supplying oxygen. Pipe 312 rotates along with the worm gear 327, thereby changing the output position and angle of liquid oxygen. The position and output angle of nozzle 313 are continuously adjusted to ensure sufficient oxygen content in the water of the breeding tank 1, avoiding any impact on sturgeon farming. When water in the mixing tank 216 is drained into the bottom of the breeding tank 1, the water level in the breeding tank 1 continuously increases. The water then returns to the heating tank 11 through the connecting pipe 13 and check valve 14, forming a circulation. Even when the liquid oxygen tank in the liquid oxygen storage mechanism 311 needs to be replaced and liquid oxygen is no longer supplied to the breeding tank 1, the oxygen content in the water of the breeding tank 1 can still be maintained, avoiding any impact on the farming results. A rectangular hole can be opened on one side of the heating tank 11 to allow rainwater to fall into the breeding tank 1 during rainy weather.The water level in the breeding tank 1 and the heating tank 11 will continuously increase, and then be able to drain out through the rectangular hole. This system can automatically adjust according to weather changes, maintaining the water level in the breeding tank 1 within a certain range.

[0065] In a winter indoor environment, the heating box 11 can heat the water inside it, and then the conveying mechanism 12 will transport it to the breeding box 1 to mix with the water in the breeding box 1, so as to ensure the water temperature in the breeding box 1 and avoid affecting the breeding effect.

[0066] When draining water from the breeding tank 1, the conveying mechanism 12 continuously transports water from the heating tank 11 into the breeding tank 1, draining it from the mixing tank 216 into the bottom of the breeding tank 1, continuously rinsing the bottom surface of the breeding tank 1 to prevent excess feed and sturgeon excrement from remaining at the bottom of the breeding tank 1. After draining, when resetting the movable frame 233, stirring column 214, protruding column 241, lifting block 243 and auger 242, simply turn off the first motor 212. Under the action of gravity, the mixing tank 216 cooperates with the rubber stopper 232, simultaneously driving the movable frame 233 to move away from the top of the breeding tank 1. After rinsing, the conveying mechanism 12 continues to transport water from the heating tank 11 into the breeding tank 1, so that the water in the breeding tank 1 can be quickly replenished.
