Description

Technical Field

[0001] This utility model relates to the field of aquaculture domestication, and more specifically, to a device for acclimatizing largemouth bass to sulfate salinity. Background Technology

[0002] Recent research and practice have shown that largemouth bass have a certain potential for adapting to saline-alkali environments and have achieved aquaculture survival in saline-alkali waters with carbonate alkalinity up to 10 mmol / L. However, the saline-alkali water type in the inland northwest region is mainly sulfate-type. Sulfate ions have a special impact on the osmolarity regulation system and gill respiratory function of fish. On the one hand, high concentrations of sulfate can easily damage the gill epithelial cell structure of fish, leading to a decrease in respiratory efficiency. On the other hand, it can interfere with the ion balance in fish and increase the burden of osmolarity regulation. This characteristic has become one of the key bottlenecks restricting the development of local saline-alkali waters and also makes the large-scale promotion of largemouth bass in this type of water face technical obstacles.

[0003] Among these processes, sulfate adaptation training for largemouth bass is a crucial step in their migration from freshwater aquaculture environments to sulfate-rich saline-alkali waters and the realization of large-scale aquaculture. Precise control of the sulfate gradient, stable maintenance of aquatic environmental parameters (such as dissolved oxygen and temperature), and real-time monitoring of fish adaptation status directly determine the success rate of adaptation and subsequent survival rate. Traditional adaptation methods often involve artificially adding sulfate solution to simple aquaculture tanks. However, artificial addition results in low precision in sulfate gradient control, making gradual adaptation difficult. Artificial addition can easily lead to sudden increases or decreases in sulfate concentration, exceeding the physiological adaptation threshold of largemouth bass and triggering stress responses or even death. Therefore, inventing a sulfate adaptation training device for largemouth bass to address these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sulfate salinity adaptation and domestication device for largemouth bass, which aims to improve the problem of low precision in artificial sulfate gradient control.

[0005] This invention is achieved as follows: a device for acclimatizing largemouth bass to sulfate salinity, comprising...

[0006] The mounting frame includes a support assembly; the acclimatization mechanism includes an acclimatization pool assembly mounted above the support assembly, the acclimatization pool assembly including a pool body, the bottom of the pool body being connected to a sulfate pool, and the inner bottom of the pool body being connected to an air pipe; the outer side of the acclimatization pool assembly is connected to a water circulation assembly, the water circulation assembly including an overflow pool, the overflow pool being connected to the top of the pool body.

[0007] In a preferred embodiment of this utility model, the support component includes an upright plate, a bottom connecting frame connected to one side of the upright plate, both ends of the bottom connecting frame being fixedly connected to the bottom side of the upright plate, and a support frame connected to the middle of the upright plate, both ends of the support frame being limited and connected to the inner wall of the upright plate.

[0008] In a preferred embodiment of this utility model, the bottom end of the upright plate is fixedly connected to a leg plate, the middle part of the support frame is hollow, the inner wall of the middle part of the support frame is fixedly connected to a connecting rod, and the two sides of the support frame are fixedly connected to a side frame.

[0009] In a preferred embodiment of this utility model, the pool body is placed above the support frame, the side frames are located on both sides of the pool body, the sulfate pool is placed above the bottom connecting frame, and a conveying pipe is connected to one side of the bottom of the bottom connecting frame, with the top of the conveying pipe connected to the bottom of the pool body.

[0010] In a preferred embodiment of this utility model, the top of the conveying pipe is connected to a connecting pipe, the bottom of the connecting pipe is equally connected to an output pipe, the output pipe is sealed through the bottom of the pool body, a partition plate is provided inside the pool body, the partition plate is equally distributed within the pool body, and the output pipe is located in the middle of the space enclosed by the pool body and the partition plate.

[0011] In a preferred embodiment of this utility model, the acclimatization pool assembly further includes an air pipe, with an air outlet pipe evenly distributed above the air pipe. The air outlet pipes pass through the bottom of the pool body, and an air inlet pipe is connected below the air outlet pipe. The air inlet pipe is connected to an external air supply device, and the air outlet pipe is located below the output pipe.

[0012] In a preferred embodiment of this utility model, the water circulation assembly further includes an overflow pipe, the top of which is connected to one side of the top of the pool body, and the other end of which is connected to one side of the top of the overflow pool, which is placed above the bottom connecting frame.

[0013] In a preferred embodiment of this utility model, the water circulation component further includes a drain pipe, which is connected to the bottom of the space enclosed by the pool body and the partition plate. A wastewater pool is provided on one side of the bottom of the pool body, and the wastewater pool is installed below the side frame. The wastewater pool and the drain pipe are arranged correspondingly.

[0014] In a preferred embodiment of this utility model, the bottom of the pool is inclined, and the interior of the pool is inclined downward toward the drain pipe.

[0015] The beneficial effects of this invention are: the sulfate salinity adaptation and acclimatization device for largemouth bass obtained by the above design has high sulfate mixing efficiency and good concentration uniformity during use.

[0016] By blowing air through the air outlet, the sulfate solution can be quickly diffused within the pool after entering through the delivery pipe, connecting pipe, and output pipe. This avoids local concentration differences and eliminates the need for additional mechanical stirring components. It reduces water disturbance (lowering the risk of stress to fish) and achieves the dual function of "mixing and oxygenation," achieving two goals at once.

[0017] Convenient and thorough sewage discharge, maintaining water cleanliness

[0018] The bottom of the tank is inclined towards the drain pipe. With the help of the valve on the drain pipe, fish excrement can be naturally collected at the drain pipe by gravity. Opening the valve will allow it to be discharged quickly, preventing the accumulation of excrement and the growth of harmful substances. At the same time, the wastewater tank and the drain pipe are set up to facilitate centralized collection and treatment of wastewater, reducing water pollution.

[0019] Stable structure, easy to install and operate

[0020] The support components form a stable frame through parts such as uprights, bottom connecting frames, support frames, and side frames. This allows for precise positioning and installation of the tank, sulfate tank, overflow tank, and wastewater tank, preventing device displacement. Furthermore, all functional components (such as delivery pipes, overflow pipes, and drainage pipes) are designed to be interconnected. During operation, only the pump and valves need to be controlled to complete processes such as sulfate injection, water circulation, and sewage discharge, reducing operational difficulty.

[0021] Gradient acclimatization has strong adaptability and high functional integration.

[0022] The tank is divided into multiple independent acclimatization spaces by partitions. Each space corresponds to a set of output pipes and air outlet pipes. Multi-gradient acclimatization can be achieved by controlling the amount of sulfate injected into different spaces. At the same time, it integrates sulfate injection (sulfate tank, conveying pipe), mixed oxygenation (air outlet pipe, air inlet pipe), water circulation (overflow pipe, overflow tank), and sewage discharge (drainage pipe, wastewater tank) functions. No additional equipment is required, and the equipment integration is significantly improved. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a device for acclimatizing largemouth bass to sulfate salinity, comprising...

[0031] Mounting frame 100 includes a support component 110; acclimatization mechanism 200 includes an acclimatization pool component 210, which is mounted above the support component 110. The acclimatization pool component 210 includes a pool body 211, with a sulfate pool 213 connected to the bottom of the pool body 211 and an air pipe 217 connected to the inner bottom of the pool body 211; a water circulation component 220 is connected to the outer side of the acclimatization pool component 210, which includes an overflow pool 222 connected to the top of the pool body 211; by blowing air through the air outlet pipe 218, the sulfate solution can be quickly pushed to diffuse within the pool body 211 after entering the pool body 211 through the delivery pipe 214, connecting pipe 215, and output pipe 216, avoiding local concentration differences and eliminating the need for additional mechanical stirring components, thus reducing water disturbance (lowering the risk of fish stress) and achieving the dual function of "mixing-oxygenation".

[0032] A precision metering pump with an accuracy of ±0.1 mL / min is installed on the connecting pipeline between sulfate tank 213 and tank body 211. This allows for precise control of the sulfate solution injection volume, preventing sudden concentration changes that could cause stress to the fish. Simultaneously, a level sensor is installed on the top of the inner wall of tank body 211 to monitor the water level in real time, preventing excessive overflow from increasing the burden on overflow tank 222 and improving the operational stability of the system.

[0033] Please see Figure 3 and Figure 4 The support assembly 110 includes a vertical plate 111. A bottom connecting frame 113 is connected to one side of the vertical plate 111. The two ends of the bottom connecting frame 113 are fixedly connected to the bottom side of the vertical plate 111. A support frame 114 is connected to the middle of the vertical plate 111. The two ends of the support frame 114 are respectively limited and connected to the inner wall of the vertical plate 111. The connection between the vertical plate 111 and the bottom connecting frame 113 and the support frame 114 is double fixed by welding and bolts. The welding strength is over 500MPa. The bolts are made of 316L stainless steel, which is resistant to salt and alkali corrosion and can prevent the parts from loosening after long-term use. A 3mm thick rubber buffer pad is pasted on the inner wall of the support frame 114, which can reduce the collision and wear between the pool body 211 and the support frame 114 and extend the service life of the device.

[0034] The bottom of the upright plate 111 is fixedly connected to the leg plate 112. The middle part of the support frame 114 is hollow. The inner wall of the middle part of the support frame 114 is fixedly connected to the connecting rod 115. The two sides of the support frame 114 are fixedly connected to the side frame 116. The bottom of the leg plate 112 is equipped with a 5cm thick rubber anti-slip pad with a friction coefficient ≥0.8, which can prevent the device from sliding on the ground. The connecting rod 115 adopts a rectangular steel tube structure with a cross-sectional size of 40mm×20mm. Compared with the round steel tube, the bending strength is increased by 30%, which can enhance the overall load-bearing capacity of the support frame 114. The inner side of the side frame 116 has a slot that can be embedded into the side of the pool body 211, further restricting the lateral displacement of the pool body 211 and improving the structural compactness.

[0035] The pool body 211 is placed above the support frame 114, and the side frames 116 are located on both sides of the pool body 211. The sulfate pool 213 is placed above the bottom connecting frame 113. A conveying pipe 214 is connected to one side of the bottom of the bottom connecting frame 113. The top of the conveying pipe 214 is connected to the bottom of the pool body 211. The conveying pipe 214 is made of UPVC material with an inner wall smoothness of ≤0.01mm to reduce the flow resistance of the sulfate solution. At the same time, a flow sensor is installed in the middle of the conveying pipe 214 with a measurement accuracy of ±0.5L / h, which can provide real-time feedback on the solution delivery volume and facilitate closed-loop control with a precision metering pump. A positioning groove is opened on the upper surface of the bottom connecting frame 113, and its size matches the bottom of the sulfate pool 213 to prevent the sulfate pool 213 from shifting and ensure that the conveying pipe 214 is accurately connected to the outlet of the sulfate pool 213.

[0036] The top of the delivery pipe 214 is connected to a connecting pipe 215, and the bottom of the connecting pipe 215 is equally connected to an output pipe 216. The output pipe 216 is sealed and penetrates the bottom of the pool body 211. A partition plate 212 is set inside the pool body 211, and the partition plate 212 is equally divided inside the pool body 211. The output pipes 216 are located in the middle of the space enclosed by the pool body 211 and the partition plate 212. The connecting pipe 215 adopts a variable diameter design, with an inlet diameter of 50mm and an outlet diameter of 30mm, which can increase the solution flow rate and ensure that the flow uniformity error of each output pipe 216 is ≤5%. The height of the partition plate 212 is 10cm lower than the top of the pool body 211, which can form an independent acclimatization space and allow a small amount of water to circulate between adjacent spaces in an emergency, avoiding the deterioration of water quality in a single space and causing mass fish deaths. An anti-clogging filter with a pore size of 0.5mm is installed at the outlet end of the output pipe 216 to prevent impurities in the pool from entering the pipe and causing blockage.

[0037] The acclimatization tank component 210 also includes an air pipe 217. Air outlet pipes 218 are evenly spaced above the air pipe 217, each penetrating the bottom of the tank body 211. An air inlet pipe 219 is connected below the air outlet pipes 218 and is connected to an external air supply device. The air outlet pipes 218 are located below the output pipe 216. An oblique air hole with a diameter of 0.3mm is opened at the top of the air outlet pipe 218, facing the output pipe 216. The ejected air bubbles can directly propel the sulfate solution discharged from the output pipe 216, increasing the mixing efficiency by 40%. A quick-connect fitting is used at the connection between the air pipe 217 and the air outlet pipe 218, with a disassembly time ≤30s, facilitating later maintenance and cleaning. A pressure regulating valve is installed on the air inlet pipe 219, with an adjustment range of 0.1-0.5MPa, allowing adjustment of the aeration rate according to the dissolved oxygen demand in the tank body 211, achieving energy-saving operation.

[0038] The water circulation component 220 also includes an overflow pipe 221. The top of the overflow pipe 221 is connected to one side of the top of the pool body 211, and the other end of the overflow pipe 221 is connected to one side of the top of the overflow pool 222. The overflow pool 222 is placed above the bottom connecting frame 113. The overflow pipe 221 is made of 316L stainless steel, which is resistant to sulfate corrosion and has a service life of ≥5 years. A fish barrier net with a mesh size of 2mm is installed at the inlet end of the overflow pipe 221 to prevent fish from entering the overflow pool 222 with the overflow water. A water quality detection sensor is installed inside the overflow pool 222 to detect parameters such as pH and dissolved oxygen. If the water quality meets the standards, the water in the overflow pool 222 can be returned to the pool body 211 by an external water pump, which increases the water resource utilization rate by 30%.

[0039] The water circulation component 220 also includes a drain pipe 224, which is connected to the bottom of the space enclosed by the pool body 211 and the partition plate 212. A wastewater pool 223 is provided on one side of the bottom of the pool body 211. The wastewater pool 223 is installed below the side frame 116 and is correspondingly set with the drain pipe 224. An electric valve is installed on the drain pipe 224 with a response time of ≤1s. Automatic sewage discharge can be achieved through timed control without manual operation. The diameter of the drain pipe 224 is 50% larger than that of the output pipe 216 to ensure a fast water flow during sewage discharge and to avoid sewage residue clogging the pipe. A sealing cover is installed on the top of the wastewater pool 223 to reduce the diffusion of odors. A sampling port is opened on the cover to facilitate regular testing of wastewater quality and provide a basis for subsequent wastewater treatment.

[0040] The inner bottom of the pool body 211 is inclined, with the inside of the pool body 211 tilting downwards towards the drain pipe 224. The inclination angle of the inner bottom of the pool body 211 is set to 5°. At this angle, the natural collection efficiency of excrement is the highest, and the thoroughness of sewage discharge is improved by 80% compared with a horizontal bottom. At the same time, it will not cause discomfort to fish due to excessive inclination. The inner bottom of the pool body 211 is covered with a ceramic wear-resistant layer with a thickness of 2mm and a surface roughness Ra≤0.8μm, which reduces the adhesion of excrement and facilitates thorough rinsing during sewage discharge. The ceramic layer is resistant to salt and alkali corrosion, which can extend the service life of the pool body 211.

[0041] Working principle: The device is installed and fixed.

[0042] In the support assembly 110, the upright plate 111 is stably supported on the ground by the leg plate 112, and the bottom connecting frame 113 is fixed to one side of the bottom of the upright plate 111 for placing the sulfate tank 213 and the overflow tank 222; the support frame 114 is fixed in the middle of the upright plate 111, and its side frame 116 limits the two sides of the tank body 211. The tank body 211 is placed above the support frame 114, and the wastewater tank 223 is installed below the side frame 116 and corresponds to the drain pipe 224.

[0043] Sulfate injection and mixing

[0044] The sulfate solution in the sulfate tank 213 is transported to the delivery pipe 214 by a pump (externally equipped), then enters the connecting pipe 215 through the delivery pipe 214, and is then equally distributed to each output pipe 216 by the connecting pipe 215, and finally injected into the independent space enclosed by the tank body 211 and the partition plate 212. At the same time, the external air supply equipment supplies air to the air outlet pipe 218 through the air inlet pipe 219. The air outlet pipe 218 blows air and bubbles at the bottom of the tank body 211, which on the one hand promotes the rapid mixing of the sulfate solution to avoid concentration differences, and on the other hand replenishes oxygen in the tank body 211 to maintain stable dissolved oxygen.

[0045] Water circulation and overflow control

[0046] When the water level in pool 211 rises to the top, the excess water flows into overflow pool 222 through overflow pipe 221 to achieve water circulation balance and prevent the water level in pool 211 from overflowing due to excessive height. The water collected in overflow pool 222 can be recycled after treatment (requires external supporting treatment equipment) to improve water resource utilization.

[0047] Sewage Discharge Operation

[0048] When fish excrement accumulates in the pool 211, the excrement will naturally collect at the drain pipe 224 because the bottom of the pool 211 is tilted towards the drain pipe 224. Open the valve on the drain pipe 224, and the excrement will be discharged into the wastewater pool 223 along with the water. After the sewage discharge is completed, close the valve to ensure that the water in the pool 211 is clean.

[0049] It should be noted that the specific model and specifications in this solution need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0050] The power supply and its principle in this solution are clear to those skilled in the art, and will not be described in detail here.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
