Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a wave-making device and an aquaculture system. Background Technology

[0002] Natural water bodies typically have undulating waves that shimmer under sunlight. However, the water in small containers like aquariums is relatively calm. To better mimic the natural environment of the organisms and promote their health, wave generation is usually necessary within the aquarium. Traditional wave generation involves installing one or more wave generators within the container. These pumps use rotating impellers to create water currents. Only when the current is strong enough can a noticeable wave effect be achieved, and the amplitude and shape of these waves differ significantly from those in natural water bodies, resulting in less than ideal results. Utility Model Content

[0003] The first objective of this invention is to provide a wave-generating device that can produce a wave effect similar to that of natural water bodies.

[0004] The second objective of this invention is to provide an aquaculture system including the aforementioned wave-making device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A first aspect of this application provides a wave-generating device, comprising:

[0007] An air chamber having at least one air inlet for immersion in water;

[0008] A pressure regulating device is provided, wherein the pressure regulating port of the pressure regulating device is connected to the air chamber through a vent pipe, and the pressure regulating device is used to periodically output positive and negative pressure to the air chamber so that the liquid in the air chamber is disturbed in a pressure environment that cycles from negative to positive pressure.

[0009] In one possible implementation, the pressure regulating device includes:

[0010] A piston assembly includes a sleeve and a piston. The first end of the sleeve is provided with a pressure regulating port, and the second end is provided with an assembly port. The piston is slidably disposed inside the sleeve.

[0011] A drive device is connected to the piston via the assembly port to drive the piston to reciprocate within the sleeve.

[0012] In one possible implementation, the drive device is a piston cylinder, or the drive device is a linear motor, or the drive device includes a rotary motor and a transmission assembly.

[0013] In one possible implementation, the driving device includes:

[0014] Rotary electric motor;

[0015] A rocker arm and connecting rod assembly includes a rocker arm and a connecting rod. A first end of the rocker arm is connected to the motor shaft of the rotary motor. A first end of the connecting rod is rotatably connected to a second end of the rocker arm. The second end of the connecting rod extends from the assembly port and is rotatably connected to the piston.

[0016] In one possible implementation, the piston includes a main plate and a circumferential annular wall, the circumferential annular wall rising from the periphery of the main plate in a direction perpendicular to the main plate, and the end of the circumferential annular wall away from the main plate forming an opening facing away from the assembly port, and the driving device being drivenly connected to the main plate.

[0017] In one possible implementation, the pressure regulating device includes a plurality of piston assemblies, the driving device is respectively connected to the piston of each piston assembly, and the pressure regulating port of each piston assembly is connected in parallel with the air chamber through the air passage.

[0018] In one possible implementation, the sleeve and the piston are in a clearance fit.

[0019] As can be seen from the above technical solutions, the wave-making device provided by this utility model includes an air chamber and an air pressure regulating device. The air chamber has at least one air inlet for immersion in water. The air pressure regulating port of the air pressure regulating device is connected to the air chamber through a ventilation pipe. The air pressure regulating device is used to periodically output positive and negative pressure to the air chamber so that the liquid in the air chamber is disturbed in the air pressure environment that changes cyclically from negative to positive pressure.

[0020] In application, the air chamber is placed inside the aquaculture container, with the air inlet of the air chamber submerged below the water surface. Then, a pressure regulator periodically outputs positive and negative pressure to the air chamber. When the pressure regulator outputs positive pressure, the pressure inside the air chamber increases, and the liquid level inside the air chamber decreases. When the pressure regulator outputs negative pressure, the pressure inside the air chamber decreases, and the liquid level inside the air chamber rises. This causes the water level in the aquaculture container to rise and fall repeatedly. When the frequency of the water level rise and fall matches the frequency of the wave undulation, it will trigger water surface resonance and produce a wave effect. The waves produced in this way are more similar to the water surface wave effect of natural water bodies, thus better mimicking the original environment of organisms and improving their condition.

[0021] A second aspect of this application provides an aquaculture system, comprising:

[0022] Aquaculture containers;

[0023] A filtration system, wherein the filtration system is connected to the aquaculture container via a water circulation system;

[0024] A wave-making device, which is the wave-making device as described in the first aspect and its possible implementations, wherein the air chamber of the wave-making device is disposed in the aquaculture container and the air outlet of the air chamber is located below the liquid level of the aquaculture container.

[0025] In one possible implementation, the aquaculture container includes a container body with a partition plate inside, which divides the inner cavity of the container body into a water zone and a land zone. An overhead filter isolation layer is provided in the land zone. The area above the overhead filter isolation layer is used to form land, and the area below the overhead filter isolation layer is used to form a water circulation zone. The water zone and the outlet of the water circulation zone are respectively connected to the inlet of the filtration system through the water circulation system. The inlet of the water zone and the water circulation zone are respectively connected to the outlet of the filtration system through the water circulation system. The air chamber is located in the water zone.

[0026] In one possible implementation, the venting pipe of the wave generator passes through the container body and the water area, extends into the air chamber through the air inlet of the air chamber, and the air outlet of the venting pipe is located above the liquid level of the aquaculture container.

[0027] In one possible implementation, a flow-damping plate is provided inside the container body on the side of the partition plate facing the land area, and a guide plate extending towards the land area and sloping downwards is provided on the top of the flow-damping plate.

[0028] In one possible implementation, an overflow component is provided in the water area, and a fish comb structure is provided on the upper and / or lower part of the overflow component. The overflow component forms an overflow area in the water area that is connected to the water area through the fish comb structure. The overflow area serves as the water outlet of the water area and is connected to the water circulation system.

[0029] In one possible implementation, the water circulation system includes a drain pipe and a water supply device. The drain pipe includes a first drain pipe, a second drain pipe, and a third drain pipe. The inlet ends of the first drain pipe and the second drain pipe extend into the overflow area, and the inlet end of the first drain pipe is higher than the inlet end of the second drain pipe. The second drain pipe is equipped with a control valve to control the on / off state of the second drain pipe. The inlet end of the third drain pipe is connected to the water circulation area. The outlet ends of the first drain pipe, the second drain pipe, and the third drain pipe are connected in parallel and then connected to the inlet end of the filtration system. The water supply device selectively connects the outlet end of the filtration system to the water circulation area and the water area.

[0030] In one possible implementation, the filtration system includes a bottom filter container with a baffle plate inside. The baffle plate divides the inner cavity of the bottom filter container into a filtration zone and a water storage zone. A water flow channel is formed between the bottom of the baffle plate and the bottom surface of the bottom filter container. A bottom filter isolation layer is provided at the bottom of the filtration zone, and filter media is arranged on the bottom filter isolation layer. The bottom filter isolation layer is used to prevent the filter media from entering the water storage zone from the water flow channel. The filtration zone serves as the water inlet of the filtration system, and the water storage zone serves as the water outlet of the filtration system.

[0031] In one possible implementation, the water supply device includes:

[0032] A water pump is installed within the water storage area;

[0050] One of the core features of this invention is to provide a wave-making device whose structural design enables it to produce water surface wave effects that are similar to those of natural water bodies.

[0051] Another core aspect of this invention is to provide an aquaculture system that includes the aforementioned wave-making device.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] This utility model discloses a wave-generating device 100. Please refer to [link / reference]. Figure 1 The wave-generating device 100 includes an air chamber 110 and an air pressure regulating device 120.

[0054] The wave-generating device 100 may include one or more air chambers 110, each air chamber 110 having at least one air inlet for immersion in water. The air chamber 110 may have only one air inlet or multiple air inlets. When the air chamber 110 has multiple air inlets, the air inlets may face the same direction or different directions. Figure 1 In the illustrated embodiment, the air inlet of the air chamber 110 is positioned downwards.

[0055] The air pressure regulating port of the air pressure regulating device 120 is connected to the air chamber 110 through the air pipe 130. The air pressure regulating device 120 is used to periodically output positive pressure and negative pressure to the air chamber 110 so that the liquid in the air chamber 110 is disturbed in the air pressure environment that changes from negative pressure to positive pressure.

[0056] When the wave-generating device 100 provided in this application is used, the air chamber 110 is placed in the aquaculture container 200 (including but not limited to glass fish tanks, acrylic fish tanks, or aquaculture tanks made of other materials), and the air inlet of the air chamber 110 is submerged below the water surface of the aquaculture container 200. Then, the air pressure regulating device 120 periodically outputs positive and negative pressure to the air chamber 110. When the air pressure regulating device 120 outputs positive pressure, the pressure inside the air chamber 110 increases and the liquid level inside the air chamber 110 decreases. When the air pressure regulating device 120 outputs negative pressure, the pressure inside the air chamber 110 decreases and the liquid level inside the air chamber 110 rises. This causes the water surface in the aquaculture container 200 to rise and fall repeatedly. When the frequency of the water surface rise and fall is consistent with the frequency of the wave undulation, it will cause water surface resonance and generate a wave effect. The waves generated in this way are more similar to the water surface wave effect of natural water bodies, thus better reflecting the original environment of organisms and improving the condition of organisms.

[0057] like Figure 2As shown, in a specific embodiment of this application, a piston 1232 type air pressure regulating device 120 is used. This air pressure regulating device 120 includes a piston assembly 123 and a driving device. The piston assembly 123 includes a sleeve 1231 and a piston 1232. A first end of the sleeve 1231 is provided with an air pressure regulating port, and a second end is provided with an assembly port. The piston 1232 is slidably disposed within the sleeve 1231, dividing the inner cavity of the sleeve 1231 into a rod chamber and a rodless chamber. The rod chamber communicates with the assembly port, and the rodless chamber communicates with the air pressure regulating port. When the piston 1232 reciprocates within the sleeve 1231, the air pressure in the rodless chamber changes, and is then output outward through the air pressure regulating port. That is, when the piston 1232 moves towards the rodless chamber, the volume of the rodless chamber decreases, and the air pressure increases. Pressure is injected into the air chamber 110 through the air pressure regulating port, thereby outputting positive pressure. The liquid level in the air chamber 110 decreases, such as... Figure 3 As shown, when piston 1232 moves towards the rod chamber, the volume of the rodless chamber increases, the air pressure decreases, and air is drawn out of the air chamber 110 through the air pressure regulating port, thereby outputting negative pressure. The liquid level in the air chamber 110 rises, as... Figure 4 As shown.

[0058] The drive unit is connected to the piston 1232 via the assembly port to drive the piston 1232 to reciprocate within the sleeve 1231. The drive unit is a piston 1232 cylinder, or a linear motor, or the drive unit includes a rotary motor 121 and a transmission assembly. The transmission assembly is used to convert the rotation of the rotary motor 121 into linear reciprocating movement. The transmission assembly includes, but is not limited to, a gear and rack assembly, a lead screw and slider assembly, a rocker arm and connecting rod assembly 122, etc.

[0059] like Figure 2 In the illustrated embodiment, the driving device includes a rotary motor 121 and a rocker arm and connecting rod assembly 122. The rotary motor 121 has a motor shaft that outputs rotational motion. The rocker arm and connecting rod assembly 122 includes a rocker arm 1221 and a connecting rod 1222. The first end of the rocker arm 1221 is connected to the motor shaft of the rotary motor 121 and is perpendicular to the motor shaft. The first end of the connecting rod 1222 is rotatably connected to the second end of the rocker arm 1221. The second end of the connecting rod 1222 extends from the assembly port and is rotatably connected to the piston 1232. When the rocker arm 1221 rotates with the motor shaft, the connecting rod 1222 drives the piston 1232 to reciprocate under the drive of the rocker arm 1221.

[0060] Furthermore, such as Figure 2As shown, in one specific embodiment of this application, the piston 1232 includes a main body plate and a circumferential ring wall. The circumferential ring wall rises from the periphery of the main body plate in a direction perpendicular to the main body plate, and the end of the circumferential ring wall away from the main body plate forms an opening facing away from the assembly port. The driving device is connected to the main body plate in a transmission connection. When the piston 1232 reciprocates in the sleeve 1231, the circumferential ring wall is at least partially always located in the inner cavity of the sleeve 1231 to prevent the piston 1232 from falling out of the sleeve 1231 and to ensure the stability of operation.

[0061] When the aquaculture container 200 is large, it is necessary to increase the wave-generating capacity of the wave-generating device 100. This can be achieved by increasing the size of the piston assembly 123 or increasing the number of piston assemblies 123. In one embodiment of this application, the air pressure regulating device 120 includes multiple piston assemblies 123. The driving device is respectively connected to the piston 1232 of each piston assembly 123. The air pressure regulating ports of each piston assembly 123 are connected in parallel to the air chamber 110 through the air pipe 130. Specifically, in Figure 5 In the embodiment shown, the air pressure regulating device 120 includes two piston assemblies 123. Correspondingly, the driving device is a dual-output shaft geared motor. The two output shafts at both ends of the motor are respectively connected to the piston 1232 of one piston assembly 123 through the rocker arm connecting rod assembly 122. The dual-output shaft geared motor drives the two piston assemblies 123 to move synchronously.

[0062] Preferably, in one embodiment of this application, the sleeve 1231 and the piston 1232 are in clearance fit. This allows air to enter and exit through the gap between the sleeve 1231 and the piston 1232, preventing the sleeve 1231 and the piston 1232 from being completely sealed. If the sleeve 1231 and the piston 1232 are completely sealed, too much internal air cannot be discharged in time, causing the water level in the air chamber 110 to drop abnormally and air to escape from below the air chamber 110; or if there is too little internal air, it cannot be replenished in time, causing the water level in the air chamber 110 to rise abnormally and water to enter the vent pipe 130.

[0063] By creating a gap between the sleeve 1231 and the piston 1232, when the piston 1232 moves towards the rodless chamber, the volume of the rodless chamber decreases, and air enters the air chamber 110 through the vent pipe 130, causing the water level inside the air chamber 110 to drop, thereby raising the water level in the aquaculture container 200. At this time, there is a slight air leakage in the gap between the sleeve 1231 and the piston 1232, but it has little impact on the air pressure inside the air chamber 110 and can reduce the movement resistance of the piston 1232. When the piston 1232 moves towards the rod chamber, the volume of the rodless chamber increases, and the air in the air chamber 110 is drawn into the rodless chamber, causing the air pressure inside the air chamber 110 to drop, thereby raising the water level inside the air chamber 110 and lowering the water level in the aquaculture container 200. At this time, there is also a slight air leakage in the gap between the sleeve 1231 and the piston 1232, preventing the liquid in the air chamber 110 from being drawn into the rodless chamber of the sleeve 1231.

[0064] The gap between the sleeve 1231 and the piston 1232 is about 1 mm. When the piston assembly 123 is placed horizontally, that is, when the axis of the piston assembly 123 is parallel to the ground, the lower surface of the piston 1232 is coated with an appropriate amount of grease to reduce frictional loss. The upper surface of the piston 1232 is not coated to prevent the gap between the sleeve 1231 and the piston 1232 from being completely sealed.

[0065] In this embodiment of the application, the reciprocating stroke of piston 1232 is about 5 centimeters. It should be noted that the stroke of piston 1232 is related to the amplitude of the generated waves and is roughly proportional. The larger the water surface area that generates waves, the greater the stroke required. Of course, it is also possible not to increase the stroke of piston 1232, but to use piston 1232 with a larger cross-sectional area or increase the number of piston assemblies 123.

[0066] The reciprocating motion frequency of piston 1232 is 68 times / minute. This frequency is adjusted by regulating the rotation speed of rotary motor 121. The higher the water level in the aquaculture container 200, the lower the suitable frequency.

[0067] When the wave generator 100 is running continuously, the piston 1232 moves back and forth, and the water level in the aquaculture container 200 rises and falls repeatedly. When the frequency of the water level rises and falls is consistent with the frequency of the wave undulation, it will cause water surface resonance and produce a wave effect.

[0068] Further optimize the above technical solution. Based on the overall layout of the aquaculture container 200, the ventilation pipe 130 can be configured as follows: Figure 1 , Figure 3 and Figure 4 As shown, it is also possible to bypass the connecting air chamber 110 from the outside of the culture container 200, as shown in the diagram. Figure 6 As shown, liquid passing through the bottom or side of the culture container 200 enters the air chamber 110 through the air inlet, without limitation.

[0069] This application also provides an aquaculture system, such as... Figure 7 As shown, the aquaculture system includes a culture container 200, a filtration system, and a wave generator 100. The culture container 200 stores water, forming a culture space. The filtration system is connected to the culture container 200 via a water circulation system 300. The filtration system can be a filter canister, back filter, trickle filter, or bottom filter. Depending on the species being cultured, filter media such as filter cotton, bacterial houses, bacterial rings, coral skeletons, and protein skimmers can be used in the filtration system. The wave generator 100 is the same as described in the above embodiment. The air chamber 110 of the wave generator 100 is located in the culture container 200, and the air inlet of the air chamber 110 is below the liquid level in the culture container 200. Since this aquaculture system uses the wave generator 100 described in the above embodiment, the technical effects of this aquaculture system are explained in the above embodiment.

[0070] Preferably, in this embodiment of the application, the aquaculture container 200 is a tidal tank for aquaculture of intertidal organisms, specifically, as shown in the example below. Figure 7 As shown, the aquaculture container 200 includes a container body, and a partition plate 210 is provided inside the container body. The partition plate 210 divides the inner cavity of the container body into a water area 200b and a land area 200a. The water area 200b is used to contain the configured seawater, and the land area 200a is used to form land for intertidal organisms to live on. The partition plate 210 is made of a material that can withstand a certain pressure and is corrosion resistant, such as a glass plate, an acrylic plate, etc.

[0071] The partition 210 can adopt various structures. For example, the partition 210 can be a straight structure, that is, the partition 210 can be connected to the bottom wall and two opposite side walls of the container body to separate the internal area of ​​the container body. The partition 210 can also be an L-shaped structure, that is, the partition 210 can be connected to the bottom wall and two adjacent side walls of the container body. The partition 210 can also be a U-shaped structure, that is, the two ends of the partition 210 are connected to one side wall and the bottom wall of the container body. The partition 210 can also be a T-shaped structure, that is, the edges of two ends of the partition 210 are connected to two opposite side walls of the container body, the edge of the other end is connected to the other side wall, and the bottom of the partition 210 is connected to the bottom of the container body. The partition 210 can also be a polygonal circumferentially closed structure, that is, the partition 210 is only connected to the bottom wall of the container body by its bottom edge.

[0072] One or more partition plates 210 can be provided inside the container body. When only one partition plate 210 is provided inside the container body, the container body is divided into a land area 200a and a water area 200b. When multiple partition plates 210 are provided inside the container body, the container body can be divided into multiple land areas 200a and a water area 200b, or multiple water areas 200b and a land area 200a. No limitation is made here.

[0073] An elevated filter isolation layer 240 is installed within the land area 200a. The land above the elevated filter isolation layer 240 is used to form land, which is composed of sand, a mixture of tidal mud and sand, and pure tidal mud. The land is generally laid out by the user. The tidal aquarium is mainly used to raise intertidal organisms and requires a land with sufficient thickness to meet their digging and hiding habits, while ensuring that the water flow rate meets the needs of rising and falling tides. A water circulation zone 200c is formed below the elevated filter isolation layer 240. The water outlets of the water zone 200b and the water circulation zone 200c are connected to the water inlet of the filtration system through the water circulation system 300, and the water inlet of the water zone 200b and the water circulation zone 200c are connected to the water outlet of the filtration system through the water circulation system 300. An air chamber 110 is set in the water zone 200b.

[0074] Specifically, such as Figure 7 As shown, the overhead filter isolation layer 240 includes a filter layer 242 and a bottom filter frame 241. The filter layer 242 blocks sand and allows water to flow. The bottom filter frame 241 is located below the filter layer 242, and a water circulation zone 200c is formed between the bottom filter frame 241 and the bottom surface of the container body.

[0075] The surface of the sand or tidal flat in land area 200a contains organic matter (algae, nematodes, organic detritus, etc.) that intertidal organisms can feed on. The algae and nematodes grow and proliferate under conditions of suitable light, sand or tidal mud, and suitable salinity and humidity. The organic detritus mainly comes from plankton and their remains, food debris, and aquatic organism excrement particles in water area 200b, which are carried by the current to land area 200a during high tide in water area 200b and then remain on the land surface. Light can come from natural sunlight or artificial light sources suitable for the growth of ordinary plants.

[0076] In this application, the filtration system is a bottom filtration system, that is, a special bottom filter container 400 is set below the aquaculture container 200. The volume of the bottom filter container 400 can be designed as needed. It is foreseeable that the larger the volume of the bottom filter container 400, the more filter media it can hold and the better the filtration effect. Under normal circumstances, in order to save space and achieve a better filtration effect, the volume of the bottom filter container 400 is generally slightly smaller than that of the aquaculture container 200.

[0077] Based on the aforementioned bottom filtration system, to save space, the air pressure regulating device 120 of the wave generator 100 is installed in the gap between the aquaculture container 200 and the bottom filter container 400. The air vent 130 of the wave generator 100 passes through the container body and the water area 200b and extends into the air chamber 110 through the air port of the air chamber 110. The air outlet of the air vent 130 is located above the liquid level of the aquaculture container 200.

[0078] To prevent the water from carrying sediment from land area 200a into water area 200b during tidal cycles, in one embodiment of this application, such as... Figure 7 As shown, a flow-damping plate 220 is provided on the side of the partition plate 210 facing the land area 200a inside the container body. A guide plate 221 extending towards the land area 200a and tilting downward is provided on the top of the flow-damping plate 220. The guide plate 221 can guide the water flow during high tide, prevent the water flow from directly impacting the land of the land area 200a, reduce the amount of mud and sand carried up, and at the same time, the mud and sand falling on the guide plate 221 can return to the land area 200a along the tilt direction of the guide plate 221.

[0079] The aforementioned flow-retardant plate 220 and partition plate 210 can be an integral structure or a separate structure.

[0080] Since intertidal organisms may enter the water area 200b during the ebb and flow of the tide, in order to facilitate the entry and exit of intertidal organisms from the water area 200b, in one embodiment of this application, the side surface of the partition plate 210 near the water area 200b is provided with a raised, rough coating or a grid plate 230 to facilitate the climbing of intertidal organisms.

[0081] Of course, in order to facilitate the climbing of intertidal organisms, the partition plate 210 can be tilted from the bottom toward the land area 200a, so that organisms can climb out of the water area 200b and return to the land area 200a.

[0082] To achieve tidal fluctuations and filtration, in one embodiment of this application, such as... Figure 7 As shown, an overflow component is provided in the water zone 200b. A fish comb structure 261 is provided on the upper and / or lower parts of the overflow component. The overflow component forms an overflow zone 250 in the water zone 200b, which is connected to the water zone 200b through the fish comb structure 261. The overflow zone 250 serves as the water outlet of the water zone 200b and is connected to the water circulation system 300.

[0083] Specifically, in this application, the overflow component is an overflow plate 260. A backpack water tank 251 is externally mounted on the tank wall of the aquaculture container 200 opposite to the overflow plate 260. The backpack water tank 251 can reduce the occupation of the internal space of the water area 200b of the container body of the aquaculture container 200, so that the overflow plate 260 is close to the tank wall of the container body, thereby visually reducing the obstructions inside the container body. An overflow gap 252 is formed between the overflow plate 260 and the tank wall of the container body where the backpack water tank 251 is mounted. A notch is provided on the upper part of the tank wall of the container body where the backpack water tank 251 is mounted to connect the overflow gap 252 and the backpack water tank 251. The overflow gap 252 and the backpack water tank 251 together constitute the overflow area 250.

[0084] The water circulation system 300 includes a drain pipe 210 and a water inlet device 320. The drain pipe 210 includes a first drain pipe 311, a second drain pipe 312, and a third drain pipe 313. The inlet ends of the first drain pipe 311 and the second drain pipe 312 extend into the overflow area 250. Figure 7 As shown in this application, the first drain pipe 311 and the second drain pipe 312 are installed in the backpack water tank 251, and the water inlet end of the first drain pipe 311 is higher than the water inlet end of the second drain pipe 312, so that the first drain pipe 311 and the second drain pipe 312 can be connected in different stages to realize water drainage. The second drain pipe 312 is equipped with a control valve 314 to control the opening and closing of the second drain pipe 312. The water inlet end of the third drain pipe 313 is connected to the water circulation zone 200c. The water outlet ends of the first drain pipe 311, the second drain pipe 312 and the third drain pipe 313 are connected in parallel and connected to the water inlet end of the filtration system. The water supply device 320 selectively connects the water outlet end of the filtration system to the water circulation zone 200c and the water zone 200b.

[0085] Furthermore, a drain flow regulating valve 315 is installed on the first drain pipe 311, the second drain pipe 312, and the third drain pipe 313 to regulate the drain flow of the first drain pipe 311, the second drain pipe 312, and the third drain pipe 313 to meet operational requirements and reduce drain noise.

[0086] like Figure 7 As shown, the filtration system includes a bottom filter container 400, and a baffle plate 410 is provided inside the bottom filter container 400. The baffle plate 410 divides the inner cavity of the bottom filter container 400 into a filtration zone 400a and a water storage zone 400b. A water flow channel 430 is formed between the bottom of the baffle plate 410 and the bottom surface of the bottom filter container 400. A bottom filter isolation layer 420 is provided at the bottom of the filtration zone 400a, and filter media 440 is arranged on the bottom filter isolation layer 420. The bottom filter isolation layer 420 is used to prevent the filter media 440 from entering the water storage zone 400b from the water flow channel 430. The filtration zone 400a serves as the water inlet of the filtration system, and the water storage zone 400b serves as the water outlet of the filtration system.

[0087] The aforementioned bottom filter container 400 is equipped with only one baffle plate 410, which separates a filtration zone 400a. The purpose is to maximize the volume of the water storage zone 400b and increase the tidal range within the aquaculture container 200. In other embodiments, multiple baffle plates 410 can be used to separate multiple filtration zones 400a, or a baffle plate 410 and an overflow plate 260 can be used, with the overflow plate 260 and baffle plate 410 arranged in a group. A flow gap exists between the overflow plate 260 and the baffle plate 410, communicating with the water flow channel 430. Furthermore, the sides and bottom of the overflow plate 260 are sealed to the side and bottom walls of the bottom filter container 400, allowing water to flow only from above the overflow plate 260, further controlling the water flow direction and achieving a better filtration effect.

[0088] like Figure 7 As shown in this application, the water supply device 320 includes a water pump 321, a first water supply pipe 322, and a second water supply pipe 323. The water pump 321 is located in the water storage area 400b. The outlet end of the first water supply pipe 322 is connected to the water circulation area 200c. The outlet end of the second water supply pipe 323 is connected to the water area 200b. The inlet ends of the first water supply pipe 322 and the second water supply pipe 323 are respectively connected to the outlet end of the water pump 321. The first water supply pipe 322 and / or the second water supply pipe 323 are equipped with a water supply flow regulating valve 327.

[0089] The outlet end of the first water supply pipe 322 is provided with a guide pipe 328. The guide pipe 328 is parallel to the bottom wall of the container body, that is, the axis of the guide pipe 328 is parallel to or approximately parallel to the bottom wall of the container body, so that the water outlet of the first water supply pipe 322 flows into the water circulation area 200c in a direction parallel or substantially parallel to the bottom wall of the container body, avoiding scouring of the overhead filter isolation layer 240.

[0090] Furthermore, the outlet end of the second water supply pipe 323 extends upward through the backpack water tank 251 to a position near the upper edge of the container body and connects to a horizontal extension pipe 324 and / or a bent pipe 325. An anti-siphon hole 326 is provided on the horizontal extension pipe 324 or the bent pipe 325.

[0091] To further optimize the above technical solution, a dry-wet separation filter 500 can be installed between the filtration zone 400a of the bottom filter container 400 and the outlet of the first drain pipe 311, the second drain pipe 312 and the third drain pipe 313 connected in parallel, so as to further improve the filtration effect and prevent food residues, animal feces and other substances from soaking in the water and affecting the water quality.

[0092] Specifically, such as Figure 7As shown, during low tide, the control valve 314 on the second drain pipe 312 is opened. Initially, water flows simultaneously from the first drain pipe 311, the second drain pipe 312, and the third drain pipe 313, with the outflow exceeding the inflow. The water level in the aquaculture container 200 begins to drop. When the water level falls below the inlet of the first drain pipe 311, only the second drain pipe 312 and the third drain pipe 313 flow, reducing the outflow and reaching equilibrium. During high tide, as... Figure 8 As shown, when control valve 314 is closed, the second drain pipe 312 cannot discharge water, the water inflow is greater than the water outflow, and the water level in the breeding container 200 begins to rise until the water level exceeds the inlet end of the first drain pipe 311. Then the first drain pipe 311 begins to discharge water, achieving water level balance.
