Description

Technical Field

[0001] The present application relates to the technical field of aquaculture, and in particular to an aquaculture box with internal circulating water. Background Art

[0002] In the field of aquaculture, the stability of the aquaculture environment and water quality have a crucial impact on the growth, survival, and quality of aquatic products. Internal recirculation aquaculture technology, with its advantages of water conservation, environmental protection, and effective control of the aquaculture environment, has become a focus of attention for many farmers and researchers. As a key piece of equipment in this technology, the performance of internal recirculation aquaculture tanks directly affects aquaculture profitability and aquatic product quality.

[0003] Chinese utility model patent publication number CN222803672U discloses an aquaculture tank with internal water circulation. A water pump pumps water from the tank into a circulation tank, where it is filtered through a filter housing to remove impurities. After passing through a regulating tank, it is heated by a heating pipe and then returned to the tank, achieving a water filtration cycle that facilitates aquaculture. However, this aquaculture tank uses only a single filter housing to filter the water. During the aquaculture process, impurities such as feed residue and fish excrement accumulate in the water over time. These impurities easily adhere to the surface of the filter housing, gradually clogging the filter pores. Once the filter housing becomes clogged, the normal circulation of the water is severely impeded, necessitating regular manual disassembly and cleaning. However, this cleaning process interrupts the normal circulation of the water. In this case, the water in the aquaculture tank cannot be filtered and purified in a timely manner, causing harmful substances to accumulate rapidly, resulting in a rapid deterioration of water quality and posing a serious threat to the survival of aquatic products.

[0004] Therefore, the present application provides an aquaculture box with internal circulating water to solve the above problems. Summary of the Invention

[0005] The present application provides an aquaculture box with internal circulating water, aiming to solve the problems raised in the background technology that the existing aquaculture box only uses a single filter cover for filtration, and once it is blocked, it needs to be manually cleaned, which interrupts the water circulation during cleaning, thereby affecting the water quality and the aquatic growth environment.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: an aquaculture tank with internal circulating water, comprising a farming tank body, a filter assembly arranged on one side of the farming tank body, a suction assembly arranged on one side of the farming tank body for conveying water in the farming tank body to the filter assembly, and a conveying assembly arranged on one side of the filter assembly for conveying filtered water in the filter assembly to the farming tank body, wherein two filter assemblies are provided; The aquaculture tank further includes a liquid level sensor in each of the two filter assemblies for monitoring whether there is clogging, and a reversing assembly disposed on the two filter assemblies and connected to the suction assembly for alternately filtering the two filter assemblies; The reversing assembly includes a connecting pipe connected to the suction assembly, two branch pipes fixedly connected to both ends of the connecting pipe and respectively connected to two filter assemblies, air bags fixedly arranged on the inner wall of one end of the connecting pipe near the two branch pipes, and a driving assembly arranged between the two filter assemblies for causing the two air bags to contract and expand alternately; by setting two filter assemblies and cooperating with liquid level sensors and reversing assemblies, uninterrupted filtration can be achieved. When one filter assembly is blocked, the driving assembly will expand the corresponding air bag to block the water flow of the blocked filter assembly, and at the same time, the other air bag will contract to switch the water flow to the unblocked filter assembly, ensuring that the water body is always in a filtering circulation state, avoiding the interruption of filtration due to the need to clean the blocked filter assembly, resulting in deterioration of water quality, creating a stable and healthy living environment for aquatic products, and improving the survival rate and quality of aquatic products. At the same time, the driving assembly is used to alternately contract or expand the two air bags to achieve water flow reversal, which is simpler and more convenient to operate.

[0007] Preferably, in order to facilitate the transportation of water in the breeding box to the filter assembly, the suction assembly includes a water inlet pipe fixedly arranged at the bottom end of the breeding box on one side close to the two filter assemblies, a water pump 1 arranged outside the breeding box and fixedly connected to the end of the water inlet pipe away from the breeding box, and a delivery pipe fixedly arranged on the end of the water pump 1 away from the water inlet pipe and fixedly connected to the connecting pipe; the water in the breeding box is powered by the water pump 1, which can ensure that the water in the breeding box can flow from the water inlet pipe into the delivery pipe, and then flow continuously from the delivery pipe to the filter assembly, thereby ensuring the normal operation of the entire filtration circulation system.

[0008] Preferably, to achieve filtration, the filter assembly includes a filter box, a partition fixedly disposed within the filter box, a through hole formed in the partition, a filter cover fixedly disposed on the partition at a position corresponding to the position above the through hole, and a receiving tank disposed within the filter box at a position corresponding to the position below the partition and connected to the filter cover for receiving filtered water. The branch pipe is fixedly connected to one side of the filter box at one end away from the connecting pipe. Through the combined design of the filter box, partition, through hole, filter cover, and receiving tank, water entering the filter box through the branch pipe is first filtered by the filter cover, then flows through the through hole into the receiving tank, and finally circulates back to the aquaculture box through the conveying assembly. This design ensures orderly water flow and improves filtration efficiency.

[0009] Preferably, in order to facilitate the transportation of filtered water in the filter assembly into the breeding box, the transportation assembly includes suction pipes fixedly arranged on the two filter boxes on the side away from the branch pipe and connected to the corresponding receiving tank, a water pump 2 arranged on one side of the two filter boxes and an outlet pipe fixedly connected to one end of the water pump 2, and the ends of the two suction pipes away from the receiving tank are fixedly connected to the end of the water pump 2 away from the outlet pipe, and the end of the outlet pipe away from the water pump 2 extends to the upper side of the breeding box; the water pump 2 provides power, and the filtered water received in the receiving tank can be transported back to the breeding box through the suction pipe and the outlet pipe, ensuring that the water in the breeding box is continuously circulated and renewed to maintain uniform and stable water quality.

[0010] Preferably, in order to achieve the alternating contraction and expansion of the two air bags, the driving assembly includes cylinders respectively fixedly connected to the two sides of the filter boxes that are close to each other, pistons respectively slidably connected to the two cylinders, air pipes respectively fixedly connected to the two cylinders at one end away from each other and fixedly connected to the corresponding air bags, push rods running through the two cylinders at one side close to each other and fixedly connected to the two pistons at both ends, a sleeve plate fixedly sleeved on the push rods, a servo electric cylinder fixedly provided on one of the filter boxes for driving the sleeve plate to move, and a guide rod running through the sleeve plate close to one end of the servo cylinder and fixedly connected to the two filter boxes at both ends, the push rod being slidably connected to the two cylinders, and the sleeve plate being slidably connected to the guide rods; the sleeve plate is driven to move by the servo electric cylinder, the sleeve plate drives the push rod, and the push rod pushes the two pistons to slide in the cylinder. Since the pistons are connected to the air bags through the air pipes, the sliding of the pistons can realize the inflation and deflation of the air bags, so that the two air bags can be alternately contracted and expanded, and then the two filter assemblies are switched in time for alternating filtration, thereby ensuring the continuity and stability of the filtration process.

[0011] Preferably, in order to further ensure the filtering effect, the aquaculture box also includes a sealing switching component arranged in the two filter boxes for alternately sealing the two through holes; the design of the sealing switching component is that when the filter cover in one of the filter boxes is blocked, the through hole of the filter box can be blocked to prevent impurities from entering the receiving groove and being sucked back to the breeding box by the conveying component when cleaning the filter cover, thereby preventing secondary pollution, ensuring that the water sent back to the breeding box is always effectively filtered, maintaining the cleanliness of the breeding water body, and creating a better living environment for aquatic products. At the same time, it can also open the through hole in the other unblocked filter box, so that the filter cover is connected to the receiving groove, facilitating filtration and ensuring uninterrupted filtration.

[0012] Preferably, in order to achieve alternating sealing of the two through holes, the sealing switching assembly includes two plates which respectively move longitudinally in the two receiving grooves and are arranged corresponding to the two through holes, connecting rods which respectively penetrate longitudinally through the two filter covers and filter boxes and are fixedly connected to the corresponding plate bodies, and a transmission assembly which is arranged between the two filter boxes and connected to the sleeve plate and is used to make the two connecting rods rise and fall alternately; through the transmission assembly connected to the sleeve plate, the movement of the sleeve plate is converted into the lifting movement of the connecting rod, thereby driving the plate body to move longitudinally. This design can achieve alternating sealing of the two through holes. When the filter cover of a filter box is clogged and needs to be cleaned, the corresponding plate body can quickly rise to seal the through hole, while the other plate body descends to open the through hole of the unblocked filter box, thereby preventing impurities from entering the receiving groove and ensuring the filtering effect.

[0013] The transmission mechanism that this two filter elements are connected should be consistent with the above-mentioned two filter elements, and the transmission mechanism that this two filter elements are connected should be consistent with the above-mentioned two filter elements.

[0014] Preferably, in order to prevent the connecting frame from detaching from the bidirectional screw, a limit block is fixedly installed on the top of the limit rod to prevent the connecting frame from detaching; the design of the limit block can enable the connecting frame to move linearly along the bidirectional screw and the limit rod, preventing the connecting frame from detaching from the bidirectional screw, ensuring the continuous and stable operation of the transmission assembly, and ensuring the normal operation of the aquaculture box filtration system.

[0015] This aquaculture tank with internal circulation water flow is equipped with two filter components and cooperates with a liquid level sensor and a reversing component to achieve uninterrupted filtration. When one filter component is blocked, the driving component will inflate the corresponding airbag to block the water flow of the blocked filter component. At the same time, the other airbag will contract, allowing the water flow to switch to the unblocked filter component, ensuring that the water body is always in a filtering circulation state, avoiding the interruption of filtration and deterioration of water quality caused by the need to clean the blocked filter component, creating a stable and healthy living environment for aquatic products, and improving the survival rate and quality of aquatic products. The aquaculture box with internal circulating water realizes water flow reversal by driving components to alternately shrink or expand two air bags, and the operation is simpler and more convenient.

[0016] The aquaculture box with internal circulating water is provided with a sealing switching component. When one of the filter covers is blocked, the corresponding through hole can be quickly blocked to prevent secondary pollution, ensuring that the water sent back to the breeding box is always effectively filtered, creating a high-quality living environment for aquatic products, and can also promptly open the unblocked through holes of the filter box to ensure uninterrupted filtration.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Example 1 This embodiment provides a kind of aquaculture box with internal circulation water, such as Figure 1-Figure 5 As shown, the aquaculture box includes a breeding box body 1, a filter assembly 3 arranged on one side of the breeding box body 1, a suction assembly 2 arranged on one side of the breeding box body 1 for transporting water in the breeding box body 1 to the filter assembly 3, and a transport assembly 4 arranged on one side of the filter assembly 3 for transporting filtered water in the filter assembly 3 to the breeding box body 1, and two filter assemblies 3 are provided; the aquaculture box also includes a liquid level sensor 5 in each of the two filter assemblies 3 for monitoring whether there is blockage, and a reversing assembly 6 arranged on the two filter assemblies 3 and connected to the suction assembly 2 for alternately filtering the two filter assemblies 3; the reversing assembly 6 includes a connecting pipe 61 connected to the suction assembly 2, two branch pipes 62 fixedly connected to both ends of the connecting pipe 61 and respectively connected to the two filter assemblies 3, air bags 63 fixedly arranged on the inner wall of one end of the connecting pipe 61 near the two branch pipes 62, and a driving assembly 64 arranged between the two filter assemblies 3 for alternately contracting and expanding the two air bags 63.

[0021] It should be added that the liquid level sensor 5 is fixedly arranged in the filter box 31. When the filter cover 34 is blocked, the water level in the space above the corresponding partition 32 of the filter box 31 will rise. The liquid level sensor 5 determines whether the filter cover 34 is blocked by monitoring the rising height of the water level. The aquaculture tank also includes a control system and a human-computer interaction terminal connected to the output end of the control system. The liquid level sensor 5 is connected to the input end of the control system, and the suction component 2, the drive component 64 and the conveying component 4 are all connected to the output end of the control system so that the operator can monitor the situation of the aquaculture tank in real time. In addition, in the prior art, the breeding box 1 uses an oxygen concentrator and a pipeline to evenly integrate concentrated oxygen into the water body to meet the oxygen needs of the cultured organisms. A heater and a cooler connected to a temperature controller are also provided in the breeding box 1. When the water temperature is lower than the set temperature, the temperature controller starts the heater. When the water temperature reaches the set temperature, the heating is automatically stopped to achieve stable control of the water temperature. When the water temperature is too high, a cooler is used to lower the water temperature.

[0022] When in use, in the initial state, the air bag 63 in the connecting branch pipe 62 of one of the filter components 3 is in a contracted state, which is used to connect with the suction component 2 for filtering, and the air bag 63 in the corresponding connecting branch pipe 62 of the other filter component 3 is in an expanded state for blocking. When the suction component 2 is started to suck the water in the breeding box 1 into the connecting pipe 61, the connecting pipe 61 will transport the water to the air bag 63 in one of the branch pipes 62 in a contracted state, and in the branch pipe 62 connected to the connecting pipe 61, and then transported to the corresponding connected filter component 3 through the branch pipe 62, and the flow The water entering the filter assembly 3 will be filtered by the filter assembly 3 to remove impurities therein, such as feed residues, fish excrement, etc., and finally the filtered water will be sucked and circulated into the breeding box 1 through the suction of the conveying assembly 4 to mix with the water in the breeding box 1. During this process, the liquid level sensor 5 in the filter assembly 3 will continuously filter the water level in the space above the partition 32 of the filter box 31. As the filtering process proceeds, if the filter assembly 3 is gradually clogged by impurities, the speed of water flowing through the filter assembly 3 will slow down, resulting in the space above the partition 32 in the filter assembly 3. When the water level rises, when the water level rises to the alarm threshold value preset by the liquid level sensor 5, the liquid level sensor 5 on the filter component 3 will convert the water level height information into an electrical signal and transmit it to the control system. After receiving the signal from the liquid level sensor 5, the control system determines that the filter component 3 is clogged and sends an instruction to start the drive component 64 to expand the air bag 63 corresponding to the clogged filter component 3, thereby blocking the communication between the branch pipe 62 connected to the filter component 3 and the connecting pipe 61. At the same time, the drive component 64 will make the air bag 63 in the other branch pipe 62 expand. The balloon 63 contracts, connecting the connecting pipe 61 with another branch pipe 62, and switching the water flow to the unblocked filter component 3 for filtration, so as to maintain the circulation of the water body and ensure the uninterrupted filtration process. Afterwards, the operator can manually clean the blocked filter component 3. Similarly, after another filter component 3 is blocked after long-term use, it can be monitored by the internal liquid level sensor 5, and the driving component 64 can be operated in time to drive the airbag 63 to expand for blocking, so that the airbag 63 connected to the cleaned filter component 3 contracts to realize the switching of water flow, and this can be used repeatedly.

[0023] Specifically, the suction assembly 2 includes a water inlet pipe 21 fixedly arranged at the bottom end of the breeding box 1 near the two filter assemblies 3, a water pump 22 arranged outside the breeding box 1 and fixedly connected to the end of the water inlet pipe 21 away from the breeding box 1, and a delivery pipe 23 fixedly arranged at the end of the water pump 22 away from the water inlet pipe 21 and fixedly connected to the connecting pipe 61; During breeding, start water pump 22. At this time, water pump 22 generates suction, so that the water in the breeding box 1 flows into water pump 22 from the water inlet pipe 21 under the action of pressure difference. Since the other end of water pump 22 is fixedly connected to the delivery pipe 23, and the delivery pipe 23 is connected to the connecting pipe 61, under the pressurized action of water pump 22, the water flowing into water pump 22 will be pressurized and flow into the delivery pipe 23, and then distributed to the corresponding connected branch pipe 62 through the connecting pipe 61, and finally enter the corresponding connected filter component 3 through the corresponding branch pipe 62 for filtration.

[0024] Furthermore, the filter assembly 3 includes a filter box 31, a partition 32 fixedly disposed in the filter box 31, a through hole 33 provided on the partition 32, a filter cover 34 fixedly disposed on the partition 32 at a position corresponding to the through hole 33, and a receiving groove 35 disposed in the filter box 31 at a position corresponding to the below of the partition 32 and connected to the filter cover 34 for receiving filtered water. The branch pipe 62 is fixedly connected to one side of the filter box 31 at one end away from the connecting pipe 61. After the water is transported to the corresponding connected branch pipe 62 through the suction component 2, the water entering the branch pipe 62 will flow into the corresponding connected filter box 31. After the water enters the filter box 31, it will first contact the filter cover 34. The water is intercepted by the filter holes on the filter cover 34, and the impurities in the water can be intercepted in the space above the receiving groove 35 corresponding to the partition 32. The filtered water will continue to flow downward through the filter holes on the filter cover 34 and pass through the through hole 33 on the partition 32. Since the receiving groove 35 is arranged at a position below the corresponding partition 32 in the filter box 31 and is connected to the filter cover 34, the filtered water passing through the through hole 33 will directly flow into the receiving groove 35 and gather in the receiving groove 35. Finally, the filtered water in the receiving groove 35 will be transported to the conveying component 4 for suction, and circulate back to the breeding box 1 for use.

[0025] It is understandable that the filter cover 34 can be fixed to the partition plate 32 by bolts to facilitate disassembly and cleaning.

[0026] Furthermore, the conveying assembly 4 includes a suction pipe 41 fixedly arranged on one side of the two filter boxes 31 away from the branch pipe 62 and connected to the corresponding receiving groove 35, a water pump 42 provided on one side of the two filter boxes 31, and a water outlet pipe 43 fixedly connected to one end of the water pump 42. The ends of the two suction pipes 41 away from the receiving groove 35 are fixedly connected to the end of the water pump 42 away from the water outlet pipe 43, and the end of the water outlet pipe 43 away from the water pump 42 extends to the upper side of the breeding box 1; After the filter assembly 3 filters the water, the filtered water will be collected in the receiving tank 35. At this time, by starting the water pump 2 42, the water pump 2 42 will generate suction, so that the filtered water in the receiving tank 35 will be sucked into the suction pipe 41 and flow into the water pump 2 42. Then, through the pressurization of the water pump 2 42, the filtered water entering the water pump 2 42 will flow into the outlet pipe 43. Since the outlet pipe 43 extends to the side above the breeding box 1 at one end away from the water pump 2 42, the filtered water that is pressurized and transported to the outlet pipe 43 will be directly transported to the top of the breeding box 1 through the outlet pipe 43, and then fall into the breeding box 1 by gravity, and mix with the water in the breeding box 1 to complete the circulation.

[0027] Furthermore, the driving assembly 64 includes a cylinder 641 fixedly connected to the mutually adjacent sides of the two filter boxes 31, a piston 642 slidably connected to the two cylinders 641, an air pipe 643 fixedly connected to the mutually distant ends of the two cylinders 641 and fixedly connected to the corresponding airbag 63, a push rod 644 passing through the mutually adjacent sides of the two cylinders 641 and fixedly connected to the two pistons 642 at both ends, a sleeve plate 645 fixedly sleeved on the push rod 644, a servo electric cylinder 646 fixedly provided on one of the filter boxes 31 for driving the sleeve plate 645 to move, and a guide rod 647 passing through one end of the sleeve plate 645 close to the servo electric cylinder 646 and fixedly connected to the two filter boxes 31 at both ends, the push rod 644 being slidably connected to the two cylinders 641, and the sleeve plate 645 being slidably connected to the guide rod 647; When one of the filter components 3 is used for filtering, the air bag 63 in the connecting branch 62 of the filter component 3 is in a contracted state, and the air bag 63 in the corresponding connecting branch 62 of the other filter component 3 is in an expanded state for blocking. When the liquid level sensor 5 in the filter component 3 used for filtering detects that the water level in the space above the corresponding partition 32 in its filter box 31 has risen to a certain height, and the water level has risen to the alarm threshold preset by the liquid level sensor 5, the liquid level sensor 5 will convert the water level height information into an electrical signal and transmit it to the control system. After receiving the signal from the liquid level sensor 5, the control system will determine that the filter cover 34 in the filter component 3 is blocked, and then the control system will send an instruction The servo electric cylinder 646 of the start-up drive component 64 is started. After the servo electric cylinder 646 is started, its piston rod extends and drives the sleeve plate 645 to move along the guide rod 647. During this process, the guide rod 647 plays a guiding role to ensure that the movement direction of the sleeve plate 645 is accurate and stable. However, as the sleeve plate 645 moves, it will drive the connected push rod 644 and the pistons 642 connected at both ends of the push rod 644 to move on the two cylinders 641 respectively. As the piston rod of the servo electric cylinder 646 extends, the push rod 644 will drive the piston 642 corresponding to the blocked filter component 3 to move in the corresponding cylinder 641 near the end of the air pipe 643, so that the gas in the corresponding cylinder 641 is compressed and transported to the corresponding air pipe 643. The airbag 63 in the branch pipe 62 connected to the blocked filter component 3 expands. As the airbag 63 expands, it will gradually block the corresponding branch pipe 62, blocking the water flow channel between the filter component 3 and the suction component 2. At the same time, the push rod 644 will pull the piston 642 corresponding to the other unblocked filter component 3 to move in the corresponding cylinder 641 away from the end of the air pipe 643. As the piston 642 moves, the volume in the corresponding cylinder 641 increases, generating negative pressure, so that the gas in the airbag 63 in the branch pipe 62 connected to the unblocked filter component 3 can be sucked back to the cylinder 641 through the corresponding connected air pipe 643. As the gas is sucked, the airbag 63 contracts, thereby the connection between the branch pipe 62 and the suction component 2 is closed. Once the connecting pipe 61 is connected, the water sucked by the suction component 2 can be switched to the unblocked filter component 3 for filtration to achieve uninterrupted filtration. When the unblocked filter component 3 is used for filtration, the operator can manually clean the blocked filter component 3. On the contrary, when the unblocked filter component 3 is blocked due to long-term use, the control system will promptly start the piston rod of the servo electric cylinder 646 to retract through the monitoring of its internal liquid level sensor 5, and drive the push rod 644 to move in the opposite direction, thereby causing the air bag 63 in the unblocked filter component 3 to expand and block the branch pipe 62 connected to it, so that the air bag 63 in the cleaned filter component 3 will shrink, allowing its branch pipe 62 to be connected to the connecting pipe 61 connected to the suction component 2.

[0028] Example 2 Different from Example 1, Figure 6-Figure 7 As shown, in order to further ensure the filtering effect, the aquaculture box also includes a sealing switching component 7 arranged in the two filter boxes 31 for alternately sealing the two through holes 33; the design of the sealing switching component 7 is that when the filter cover 34 in one of the filter boxes 31 is blocked, the through hole 33 of the filter box 31 can be blocked to prevent impurities from entering the receiving groove 35 and being sucked back to the breeding box 1 by the conveying component 4 when cleaning the filter cover 34, thereby preventing secondary pollution and ensuring that the water sent back to the breeding box 1 is always effectively filtered, maintaining the cleanliness of the breeding water body, and creating a better living environment for aquatic products. At the same time, the through hole 33 in the other unblocked filter box 31 can be opened, so that the filter cover 34 is connected to the receiving groove 35, which facilitates filtration and ensures uninterrupted filtration.

[0029] Among them, the sealing switching assembly 7 includes two plates 71 that move longitudinally in the two receiving grooves 35 and are arranged corresponding to the two through holes 33, a connecting rod 72 that passes through the two filter covers 34 and the filter box 31 longitudinally and is fixedly connected to the corresponding plate 71, and a transmission assembly 73 that is arranged between the two filter boxes 31 and connected to the sleeve plate 645 for alternately lifting and lowering the two connecting rods 72. The transmission assembly 73 includes a tooth plate 731 that moves laterally on one side of the two filter boxes 31 and is fixedly connected to one end of the sleeve plate 645 near the servo electric cylinder 646, a tooth plate 731 that is rotatably connected between the two filter assemblies 3 and is located away from the sleeve A connecting shaft 732 on one side of the plate 645, a gear 733 fixedly sleeved on the connecting shaft 732 and meshing with the tooth plate 731, a bidirectional screw 734 fixedly connected to the connecting shaft 732 at a position above the corresponding tooth plate 731, a connecting frame 735 provided at both ends of the bidirectional screw 734 and screwed to the bidirectional screw 734, and two limiting rods 736 fixedly provided on both sides of the connecting shaft 732 and respectively passing through the two connecting frames 735, the ends of the two connecting frames 735 away from the bidirectional screw 734 are respectively fixedly connected to the top ends of the corresponding connecting rods 72, and the two connecting frames 735 are respectively slidably connected to the corresponding limiting rods 736; When one of the filter components 3 is filtering, the plate 71 for blocking the through hole 33 will drop into the corresponding receiving groove 35, and the plate 71 of the other blocked filter component 3 will rise to block its through hole 33 to prevent impurities from entering the receiving groove 35 and being sucked by the conveying component 4. Afterwards, when the filter cover 34 of one of the filter components 3 is blocked, the liquid level sensor 5 detects that the water level rises and reaches the preset alarm threshold. The control system sends a command to start the piston rod of the servo electric cylinder 646 of the drive component 64 to extend and drive the sleeve plate 645 to move. The tooth plate 731 will move with The sleeve plate 645 moves laterally. At this time, the movement of the tooth plate 731 will drive the gear 733 meshing with it to rotate. Since the gear 733 is fixedly sleeved on the connecting shaft 732, the connecting shaft 732 will also rotate accordingly. Then, the rotation of the connecting shaft 732 will drive the bidirectional screw 734 fixedly connected thereto to rotate. Since the connecting frame 735 is screwed to the bidirectional screw 734, and the two limiting rods 736 respectively pass through the two connecting frames 735 and are fixedly set on both sides of the connecting shaft 732, the rotation of the bidirectional screw 734 causes the two connecting frames 735 to make a straight line along the limiting rod 736 When the filter cover 34 is cleaned, the filter housing 31 is opened, and the filter housing 31 is opened, and the filter housing 31 is opened, and the filter housing 31 is opened, and the filter housing 31 is opened, and the filter housing 31 is opened, and the filter housing 31 is opened. When the filter cover 34 is cleaned, the filter housing 31 is opened, and the filter housing 31 is opened, the filter housing 31 is opened, and the filter housing 31 is opened. When the filter cover 34 is cleaned, the filter housing 31 is opened, and the filter housing 31 is opened, the filter housing 31 is opened, and the filter housing 31 is opened. When the filter cover 34 is cleaned, the filter housing 31 is opened, and the filter housing 31 is opened. When the filter cover 34 is opened, the filter housing 31 is opened, and the filter housing 31 is opened, the filter housing 31 is opened. The corresponding plate 71 that moves downward will also descend synchronously, thereby keeping the through hole 33 of the filter box 31 unobstructed, ensuring that the filtering work can continue on the unblocked filter cover 34. On the contrary, after the blocked filter cover 34 is cleaned and the unblocked filter cover 34 is blocked, the control system drives the component 64 to retract the piston rod of the servo electric cylinder 646. The retraction of the piston rod will cause the transmission component 73 to move in the opposite direction, thereby driving the plate 71 in the cleaned filter box 31 to descend for connected filtration, and the plate 71 in the blocked filter box 31 will rise for blocking.

[0030] In addition, in order to prevent the connecting frame 735 from detaching from the bidirectional screw 734, a limit block 737 is fixedly installed on the top of the limit rod 736 to prevent the connecting frame 735 from detaching; the design of the limit block 737 can enable the connecting frame 735 to move linearly along the bidirectional screw 734 and the limit rod 736, preventing the connecting frame 735 from detaching from the bidirectional screw 734, ensuring the continuous and stable operation of the transmission assembly 73 and ensuring the normal operation of the aquaculture box filtration system.

[0031] It should be noted that a flexible seal, such as a rubber sealing ring, is provided at the position where the filter cover 34 corresponds to the connecting rod 72. The rubber sealing ring has good elasticity and can fit tightly to the surface of the connecting rod 72 to prevent water from passing through. When the connecting rod 72 moves longitudinally, the flexibility of the rubber sealing ring enables it to adapt to the movement of the connecting rod 72 without hindering its movement, while ensuring the sealing effect.

Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
