Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a net cage for raising oval pomfret and its usage method. Background Technology

[0002] Oval pomfret is one of the important species in deep-water cage culture in southern China. It was originally a species with strong disease resistance and few diseases among artificially cultured fish. However, in recent years, due to large-scale development and high-density culture, the number of viruses has increased. In the process of culture, while strengthening water quality and feed management, we must also adhere to the principle of "prevention first, combined with treatment".

[0003] In the prior art, a net cage for oval pomfret farming, disclosed in CN211064668U, includes a device body. The top of the device body has a top plate, and the top of the top plate has a movable plate. The top of the movable plate has a threaded tube, and a threaded rod is movably connected to the inner cavity of the threaded tube. A first bearing is fixedly connected to the movable plate, and the bottom of the threaded tube is fixedly connected to the inner cavity of the first bearing. A slot matching the threaded rod is opened on the top plate. The bottom of the threaded tube passes through the inner cavity of the first bearing and extends into the device body. An oxygenation pump is fixedly connected to the bottom end of the threaded rod, and the bottom of the oxygenation pump has aeration holes. A uniformly distributed cover is provided outside the oxygenation pump. When in use, this net cage for oval pomfret farming can provide oxygen to all the oval pomfret inside the device body by adjusting the height and lateral position of the oxygenation pump. Compared with the prior art, this device has the characteristic of high oxygenation efficiency.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Because existing net cages are set up in seawater, a large number of plankton or impurities will adhere to the side walls of the net cages. However, existing net cages often do not have cleaning devices. Although some equipment is equipped with brushes to clean the net cages, after prolonged use, a large amount of impurities will remain on the brushes. Once too much impurities accumulate, the cleaning effect of the brushes on the net cages will become poor. Summary of the Invention

[0006] The purpose of this invention is to provide a net cage for the aquaculture of oval pomfret and its method of use, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An oval pomfret farming net cage includes several floats, several filter plates and a filter plate bottom plate, wherein the floats and filter plates are fixedly connected by screws, the floats are fixedly connected by screws, and the filter plates are fixedly connected by screws.

[0009] The filter screen includes a frame and a filter plate. The filter plate is fixedly mounted on the frame. A sliding box is fixedly mounted on one side of the frame. A turbine box is fixedly mounted on one end of the sliding box. The turbine box is fixedly connected to an inlet pipe and a drain pipe.

[0010] The filter screen base plate is fixedly installed at the bottom of the turbine box, and several filter screen plates and filter screen base plates together form a mesh box;

[0011] The sliding box is equipped with a cleaning component for cleaning the filter plate.

[0012] Preferably, the cleaning assembly includes a rotating shaft rotatably disposed in a sliding box, one end of the rotating shaft passing through the sliding box and extending into the turbine housing, a turbine blade being rotatably disposed in the turbine housing, and the turbine blade being fixedly disposed on the rotating shaft;

[0013] A bidirectional screw is rotatably mounted in the sliding box. The bidirectional screw is fixedly sleeved on the rotating shaft. A slider is movably sleeved on the bidirectional screw. A rocker block matching the bidirectional screw is rotatably mounted on the slider. An anti-rotation rod is fixedly mounted in the sliding box. An anti-rotation hole matching the anti-rotation rod is opened on the slider.

[0014] A guide rod is fixedly mounted on the frame, and a guide block is movably mounted on the guide rod;

[0015] A brush plate for cleaning the filter plate is provided between the slider and the guide block, and a number of brush bristles are fixedly provided on the brush plate.

[0016] When water or air flows through the turbine box, the turbine blades rotate under the impact of the water or air, causing the rotating shaft to rotate. The rotating shaft then drives the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the slider to move up and down in the sliding box via the rocker block, thereby driving the brush plate to clean the filter plate.

[0017] Preferably, the brush plate is slidably mounted on the slider and guide block via a push rod, and a compression spring is fixedly mounted between the push rod and the slider and guide block respectively. Wedge blocks are fixedly mounted on the frame and the sliding box.

[0018] When the wedge and the push rod are engaged, the push rod, under the compression of the wedge, drives the brush plate to move away from the filter plate. When the wedge and the push rod are disengaged, the push rod, under the compression of the spring, drives the brush plate to return to its original position and fit against the slider and the guide block.

[0019] Preferably, the brush plate is slidably provided with a first cleaning plate via a plurality of sliding rods, and a plurality of cleaning blocks for cleaning the gaps between the brush bristles are fixedly provided on the first cleaning plate. Driven racks are fixedly provided at both ends of the first cleaning plate. Gears are rotatably provided on the guide block and the slider. The gears mesh with the driven racks. A plurality of active racks are fixedly provided on the brush plate. The active racks mesh with the gears.

[0020] When the wedge and the push rod engage, the push rod, under the pressure of the wedge, drives the brush plate to move away from the filter plate. The active rack on the brush plate drives the slider and the gear on the guide block to rotate. The rotation of the gear drives the first cleaning plate to move closer to the filter plate through the driven rack, and the cleaning block cleans the gaps in the brush bristles.

[0021] Preferably, the first cleaning plate is movably mounted with a second cleaning plate via a plurality of sliding columns, and a plurality of cleaning blocks are also fixedly mounted on the second cleaning plate. The cleaning blocks on the second cleaning plate correspond in position to the cleaning blocks on the first cleaning plate. A spring is fixedly mounted between the plurality of sliding columns and the first cleaning plate, and a cam is fixedly mounted at one end of the gear.

[0022] When the gear rotates, it drives the cam to rotate synchronously. When the cam rotates, the second cleaning plate is driven by the spring force to move closer to the first cleaning plate. The first cleaning plate and the second cleaning plate work together to clean the gaps in the bristles.

[0023] Preferably, a nozzle is fixedly disposed between the slider and the guide block. The nozzle has several spray holes. One end of the nozzle is fixedly connected to a first one-way valve. The first one-way valve is fixedly connected to a bellows pipe. One end of the bellows pipe is fixedly connected to a second one-way valve. The second one-way valve is fixedly disposed on the sliding box.

[0024] Preferably, a plurality of brush rods are rotatably arranged on the filter screen base plate, a fixing ring is fixedly arranged on the plurality of brush rods, and a plurality of blades are fixedly arranged on the fixing ring;

[0025] A chip removal plate is rotatably mounted on the filter screen base plate, a lever is fixedly mounted on the chip removal plate, and a reset spring is fixedly mounted between the chip removal plate and the filter screen base plate.

[0026] Preferably, the drainage pipe is fixedly connected to several secondary pipes, and a valve is movably installed at one end of each of the secondary pipes;

[0027] When the brush moves toward the drain pipe and squeezes the valve, water sprays out from several secondary pipes to clean the brush.

[0028] One method of use includes the following steps:

[0029] S1: First, the operator uses screws to connect the float to the filter screen plate, then uses screws to connect the assembled float to the filter screen plate, and then fixes the filter screen base plate to the bottom of several turbine boxes, so that several filter screen plates and filter screen base plates together form a screen box. Then, several water inlet pipes are connected to the water pump. When the water pump is turned on, the water flows through the water inlet pipe and turbine box, and is discharged through the end of the drain pipe. The water flow sprayed from the drain pipe impacts the blades on the fixed ring. The fixed ring rotates under the drive of the blades, and the brush rod on the fixed ring cleans the filter screen base plate.

[0030] The brush rod intermittently contacts the lever on the chip removal plate, causing the chip removal plate to rotate at a certain angle, allowing the impurities accumulated on the bottom plate of the filter screen to be discharged through the chip removal plate.

[0031] S2: When water flows through the turbine box, the water flow drives the turbine blades in the turbine box to rotate. The rotation of the turbine disk drives the rotating shaft to rotate. The rotation of the rotating shaft drives the bidirectional screw in the sliding box to rotate. The bidirectional screw drives the slider to reciprocate linearly on the anti-rotation rod through the swing block. When the slider reciprocates linearly, it drives the brush plate fixed on the slider to clean the filter plate.

[0032] S3: When the slider drives the brush plate to reciprocate linearly, the driven rack drives the first cleaning plate to move closer to the filter plate, and the cleaning block cleans the gaps of the brush bristles.

[0033] S4: During the up-and-down movement of the brush plate, it will also squeeze or extend the accordion tube, and the water flow will be sprayed from the spray hole onto the filter plate to clean the impurities attached to the filter plate.

[0034] S5: When the brush moves toward the drain pipe, it squeezes the valve. The valve opens under the pressure of the brush, and water sprays out from several secondary pipes to clean the brush.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. By setting up a cleaning device, when water flows through the turbine box, the bidirectional screw rotates and drives the brush plate to move up and down to clean the filter plate, preventing impurities from accumulating on the filter plate and causing filter plate blockage, which would affect the growth environment of the oval pomfret;

[0037] 2. By setting up the push rod and wedge, when the push rod and wedge are engaged, the brush rod will be driven to move away from the filter plate. At this time, the brush plate is disengaged from the filter plate. At the same time, the first cleaning plate moves towards the filter plate under the drive of the gear, cleaning away the impurities accumulated in the gaps of the brush bristles.

[0038] 3. With the second cleaning plate, when the first cleaning plate moves closer to the filter plate under the drive of the gear, the cam on the gear rotates. At this time, the second cleaning plate moves closer to the first cleaning plate under the action of the spring. The first and second cleaning plates work together to clean the gaps in the bristles. It should be noted that when the cam returns to its original position (i.e., when the push rod and the wedge disengage), the cam will squeeze the second cleaning plate, causing the second cleaning plate to move away from the first cleaning plate. At this time, the distance between the second and first cleaning plates increases, and the gaps also increase. The first and second cleaning plates will not interfere with or affect the bristles when they return to their original position, thus increasing the service life of the bristles.

[0039] 4. Due to the arrangement of the accordion tube, the brush plate will squeeze or extend during its up-and-down movement. The accordion tube is connected to a first one-way valve and a second one-way valve. When the brush plate moves towards the first one-way valve, the accordion tube will extend. At this time, the first one-way valve will close and the second one-way valve will open, and the water will fill the inside of the accordion tube. When the brush plate moves towards the second one-way valve, the accordion tube will be compressed. The first one-way valve will open and the second one-way valve will close. At this time, the water will enter the spray pipe through the first one-way valve and then be sprayed onto the filter plate from the spray hole to clean the impurities attached to the filter plate.

[0040] During use, the operator turns on the water pump, and the water flows through the inlet pipe and turbine box, and is discharged through the end of the drain pipe. The water jet from the drain pipe impacts the blades on the fixed ring, and the fixed ring rotates under the drive of the blades. The brush rod on the fixed ring cleans the filter screen bottom plate. At the same time, the water flow drives the turbine blades in the turbine box to rotate, and the rotation of the turbine disk drives the rotating shaft to rotate. The rotation of the rotating shaft drives the bidirectional screw in the sliding box to rotate. The bidirectional screw drives the slider to reciprocate linearly on the anti-rotation rod through the swing block. When the slider reciprocates linearly, it drives the brush plate fixed on the slider to clean the filter plate. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-9 The present invention provides a technical solution:

[0053] Example 1:

[0054] An oval pomfret farming net cage includes several floats 1, several filter screens 2 and filter screen bottom plate 3. The floats 1 and the filter screens 2 are fixedly connected by screws, the floats 1 are fixedly connected by screws, and the filter screens 2 are fixedly connected by screws.

[0055] In this embodiment, the float 1 is a hollow plastic bucket or metal tube. The float 1 is sealed, so it can float on the water surface. The float 1 is provided with a horizontal board for the breeding personnel to walk on. The float 1 can be formed into a suitable circumference according to the breeding needs. It has a wide range of applications. It is only necessary to select a filter screen bottom plate 3 of a suitable diameter according to the circumference of the float 1.

[0056] The filter screen plate 2 includes a frame 4 and a filter plate 5. The filter plate 5 is fixedly mounted on the frame 4. A sliding box 6 is fixedly mounted on one side of the frame 4. A turbine box 10 is fixedly mounted on one end of the sliding box 6. The turbine box 10 is fixedly connected to an inlet pipe 8 and a drain pipe 9.

[0057] In this embodiment, the filter plate 5 is a rigid mesh plate made of plastic or metal. This not only prevents pomfret from damaging the filter plate 5, but also prevents external fish from damaging the filter plate 5 and entering the net cage. Both the sliding box 6 and the turbine box 10 have round holes for the rotating shaft 11 to rotate. The operator connects the water pump and the inlet pipe 8 through pipes. All inlet pipes 8 can be connected to a single high-power water pump, or each inlet pipe 8 can be connected to a single low-power water pump (the water pump and pipes are not shown in the figure; the above device is mature prior art and will not be described in detail). This technology is well known to those skilled in the art and is a commonly used device in this field, so it will not be described in detail here. The model of the water pump can be selected according to parameters such as power and speed, which will also not be described in detail here.

[0058] The filter screen base plate 3 is fixedly installed at the bottom of the turbine box 10, and several filter screen plates 2 and the filter screen base plate 3 together form a mesh box;

[0059] The sliding box 6 is equipped with a cleaning component for cleaning the filter plate 5;

[0060] Based on the above embodiments, this embodiment describes the cleaning component in the above embodiments. The cleaning component includes a rotating shaft 11 rotatably disposed in the sliding box 6. One end of the rotating shaft 11 passes through the sliding box 6 and extends into the turbine box 10. A turbine blade 12 is rotatably disposed in the turbine box 10. The turbine blade 12 is fixedly disposed on the rotating shaft 11.

[0061] In this embodiment, the rotating shaft 11 passes through the contact surface between the sliding box 6 and the turbine box 10. The operator can install bearings on both sides of the rotating shaft 11 to reduce the friction when the rotating shaft 11 rotates. When the water flows from the inlet pipe 8 through the turbine box 10 into the drain pipe 9, the water pumped into the inlet pipe 8 by the water pump can fully drive the turbine blades 12 to rotate. This technology is well known to those skilled in the art and is a commonly used device in this art. It will not be described in detail here.

[0062] A bidirectional screw 13 is rotatably mounted in the sliding box 6. The bidirectional screw 13 is fixedly sleeved on the rotating shaft 11. A slider 17 is movably sleeved on the bidirectional screw 13. A rocker block 14 matching the bidirectional screw 13 is rotatably mounted on the slider 17. An anti-rotation rod 15 is fixedly mounted in the sliding box 6. An anti-rotation hole 16 matching the anti-rotation rod 15 is opened on the slider 17. A guide rod 18 is fixedly mounted on the frame 4. A guide block 19 is movably mounted on the guide rod 18.

[0063] The bidirectional screw 13 and the rocker block 14 in this embodiment are technologies well known to those skilled in the art and are commonly used devices in this art. They will not be described in detail here. By setting the anti-rotation rod 15 and the guide rod 18, the slider 17 can move up and down stably along the axis of the bidirectional screw 13.

[0064] A brush plate 20 for cleaning the filter plate 5 is provided between the slider 17 and the guide block 19. Several bristles 21 are fixedly provided on the brush plate 20.

[0065] When water or air flows through the turbine box 10, the turbine blades 12 rotate under the impact of the water or air flow, driving the rotating shaft 11 to rotate. The rotating shaft 11 drives the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 drives the slider 17 to move up and down in the sliding box 6 through the rocker block 14, thereby driving the brush plate 20 to clean the filter plate 5.

[0066] Example 2:

[0067] Based on Embodiment 1, considering that the brush plate 20 cleans the filter plate 5 for a long time, a large amount of impurities will also adhere to the bristles 21 on the brush plate 20. The large accumulation of these impurities will cause the cleaning effect of the brush plate 20 to deteriorate. Therefore, in this embodiment, a first cleaning plate 26 and a second cleaning plate 32 are set to clean the gaps of the bristles 21 on the brush plate 20. The brush plate 20 is slidably set on the slider 17 and the guide block 19 by the top rod 22. A compression spring 23 is fixedly set between the top rod 22 and the slider 17 and the guide block 19 respectively. A wedge block 24 is fixedly set on the frame 4 and the sliding box 6.

[0068] When the wedge 24 engages with the push rod 22, the push rod 22, under the pressure of the wedge 24, drives the brush plate 20 to move away from the filter plate 5. When the wedge 24 disengages from the push rod 22, the push rod 22, under the pressure of the compression spring 23, drives the brush plate 20 to reset and engage with the slider 17 and the guide block 19.

[0069] It should be noted that in order for the bristles 21 to effectively clean the filter plate 5, the ends of the bristles 21 need to penetrate the filter holes of the filter plate 5. Therefore, when cleaning the gaps of the bristles 21 using the first cleaning plate 26 and the second cleaning plate 32, the brush plate 20 needs to be moved away from the filter plate 5. Therefore, in this embodiment, the aforementioned wedge block 24 and other devices are provided to push the brush plate 20 away from the filter plate 5, so that the bristles 21 are away from the filter plate 5.

[0070] A first cleaning plate 26 is slidably mounted on a brush plate 20 via a number of sliding rods 25. A number of cleaning blocks 27 for cleaning the gaps between the bristles 21 are fixedly mounted on the first cleaning plate 26. Driven racks 28 are fixedly mounted at both ends of the first cleaning plate 26. Gears 29 are rotatably mounted on the guide block 19 and the slider 17. The gears 29 mesh with the driven racks 28. A number of active racks 30 are fixedly mounted on the brush plate 20. The active racks 30 mesh with the gears 29.

[0071] When the wedge 24 engages with the push rod 22, the push rod 22, under the pressure of the wedge 24, drives the brush plate 20 to move away from the filter plate 5. The active rack 30 on the brush plate 20 drives the slider 17 and the gear 29 on the guide block 19 to rotate. The rotation of the gear 29 drives the first cleaning plate 26 to move closer to the filter plate 5 through the driven rack 28. The cleaning block 27 cleans the gaps of the brush bristles 21.

[0072] In this embodiment, since the first cleaning plate 26 and the brush plate 20 are movably connected by a slide rod 25, and the slide rod 25 is fixedly installed on the first cleaning plate 26, the slide rod 25 can provide guidance for the first cleaning plate 26. Therefore, the first cleaning plate 26 can move linearly on the brush plate 20 in a better manner. The operator can improve the stability of the slide rod 25 by adding a guide sleeve or increasing the thickness of the brush plate 20.

[0073] The first cleaning plate 26 is movably provided with a second cleaning plate 32 via a plurality of sliding columns 31. A plurality of cleaning blocks 27 are also fixedly provided on the second cleaning plate 32. The cleaning blocks 27 on the second cleaning plate 32 correspond to the positions of the cleaning blocks 27 on the first cleaning plate 26. A spring 33 is fixedly provided between the plurality of sliding columns 31 and the first cleaning plate 26. A cam 34 is fixedly provided at one end of the gear 29.

[0074] When gear 29 rotates, it drives cam 34 to rotate synchronously. When cam 34 rotates, the second cleaning plate 32 is driven to move closer to the first cleaning plate 26 by the elastic force of spring 33. The first cleaning plate 26 and the second cleaning plate 32 work together to clean the gaps of the bristles 21.

[0075] It should be noted that although the first cleaning plate 26 and the second cleaning plate 32 can be combined to clean the gaps in the bristles 21, and considering that combining the first cleaning plate 26 and the second cleaning plate 32 can effectively remove impurities from the bristles 21, when the first cleaning plate 26 and the second cleaning plate 32 are fixed together, when the first cleaning plate 26 and the second cleaning plate 32 move towards the brush plate 20 (i.e., when they return to their original position after cleaning the bristles 21), the fixedly connected first cleaning plate 26 and the second cleaning plate 32 are very likely to squeeze and deform the bristles 21. Therefore, in this embodiment, the second cleaning plate 32 is squeezed by the cam 34. When the first cleaning plate 26 returns to its original position (i.e., when the first cleaning plate 26 moves towards the brush plate 20), the second cleaning plate 32 will move away from the first cleaning plate 26 under the squeezing of the cam 34, so that a large gap is formed between the first cleaning plate 26 and the second cleaning plate 32, which does not affect the bristles 21.

[0076] Example 3:

[0077] Based on Embodiment 2, this embodiment includes components such as a nozzle 35. When the slider 17 moves up and down, water jets from the nozzle holes 36 on the nozzle 35 impact the filter plate 5 and clean it. A nozzle 35 is fixedly installed between the slider 17 and the guide block 19. The nozzle 35 has several nozzle holes 36. One end of the nozzle 35 is fixedly connected to a first one-way valve 37. The first one-way valve 37 is fixedly connected to a bellows pipe 38. One end of the bellows pipe 38 is fixedly connected to a second one-way valve 39. The second one-way valve 39 is fixedly installed on the sliding box 6.

[0078] During the up-and-down movement of the brush plate 20, the bellows tube 38 is compressed or extended. In this embodiment, the bellows tube 38 is equipped with components such as a spring 33 to prevent bending during compression or extension. This technology is well-known to those skilled in the art and is a commonly used device in this field, so it will not be described in detail here. The bellows tube 38 is connected to a first one-way valve 37 and a second one-way valve 39. When the brush plate 20 moves toward the first one-way valve 37, the bellows tube 38 will extend. At this time, the first one-way valve 37 closes, and the second one-way valve 39 extends. When the second one-way valve 39 is opened, water will fill the inside of the bellows tube 38. When the brush plate 20 moves toward the second one-way valve 39, the bellows tube 38 is compressed, the first one-way valve 37 opens, and the second one-way valve 39 closes. At this time, the water flows through the first one-way valve 37 into the spray pipe 35, and then sprays from the spray hole 36 onto the filter plate 5 to clean the impurities attached to the filter plate 5. The first one-way valve 37 and the second one-way valve 39 in this embodiment are technologies well known to those skilled in the art and are commonly used devices in this art. They will not be described in detail here.

[0079] Example 4:

[0080] A number of brush rods 40 are rotatably mounted on the filter screen base plate 3. A fixing ring 41 is fixedly mounted on the brush rods 40. A number of blades 42 are fixedly mounted on the fixing ring 41.

[0081] A chip removal plate 43 is rotatably mounted on the filter screen base plate 3, a lever 44 is fixedly mounted on the chip removal plate 43, and a reset spring 45 is fixedly mounted between the chip removal plate 43 and the filter screen base plate 3.

[0082] When the water pump is turned on, the water flows through the inlet pipe 8 and the turbine box 10, and is discharged through the end of the drain pipe 9. The water jet from the drain pipe 9 impacts the blades 42 on the fixed ring 41. The fixed ring 41 rotates under the drive of the blades 42, and the brush rod 40 on the fixed ring 41 cleans the filter screen base plate 3.

[0083] When the brush rod 40 contacts the lever 44 on the chip removal plate 43, the brush rod 40 drives the chip removal plate 43 to rotate at a certain angle through the lever 44, so that the impurities accumulated on the filter screen bottom plate 3 are discharged through the chip removal plate 43. When the lever 44 disengages from the brush rod 40, the chip removal plate 43 is reset under the action of the reset spring 45.

[0084] It should be noted that the operator can select a chip removal plate 43 of appropriate size according to the size of the pomfret to prevent the pomfret from escaping. The water flow sprayed from the drainage pipe 9 is also sufficient to drive the fixed ring 41 to rotate. This technology is well known to those skilled in the art and is a commonly used device in this field. It will not be described in detail here.

[0085] Example 5:

[0086] Several secondary pipes 46 are fixedly connected to the drainage pipe 9. A valve 47 is movably installed at one end of each secondary pipe 46. In this embodiment, the valve 47 is equipped with a button. The valve 47 is similar to the principle of a bicycle valve core. A cylinder that can be pressed down is provided on the valve 47. When the cylinder is pressed down, water will spray out from the valve 47. This is a technology well known to those skilled in the art and is a commonly used device in this field. It will not be described in detail here. When the brush plate 20 moves towards the drainage pipe 9 and squeezes the valve 47, water will spray out from the secondary pipes 46 to clean the brush plate 20.

[0087] It should be noted that although the secondary pipe 46 can spray water continuously, considering that the drainage pipe 9 also needs to spray water to drive the fixed ring 41 to rotate, in this embodiment, a valve 47 and other components are provided to consider energy loss. The valve 47 will only spray water when the brush plate 20 presses the valve 47. At this time, the water will impact the brush bristles 21 on the brush plate 20 to further clean the brush bristles 21.

[0088] A method of use, comprising the above-mentioned oval pomfret aquaculture net cage, includes the following steps:

[0089] S1: First, the operator uses screws to connect the float 1 to the filter screen plate 2, then uses screws to connect the assembled float 1 to the filter screen plate 2, and then fixes the filter screen base plate 3 to the bottom of several turbine boxes 10, so that several filter screen plates 2 and filter screen base plates 3 together form a screen box. Then, several water inlet pipes 8 are connected to the water pump. When the water pump is turned on, the water flows through the water inlet pipes 8 and turbine boxes 10, and is discharged through the end of the drain pipe 9. The water flow sprayed from the drain pipe 9 impacts the blades 42 on the fixed ring 41. The fixed ring 41 rotates under the drive of the blades 42, and the brush rod 40 on the fixed ring 41 cleans the filter screen base plate 3.

[0090] The brush rod 40 intermittently contacts the lever 44 on the chip removal plate 43, causing the chip removal plate 43 to rotate at a certain angle, so that the impurities accumulated on the filter screen bottom plate 3 can be discharged through the chip removal plate 43.

[0091] S2: When water flows through the turbine box 10, the water flow drives the turbine blades 12 in the turbine box 10 to rotate. The rotation of the turbine disk drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the bidirectional screw 13 in the sliding box 6 to rotate. The bidirectional screw 13 drives the slider 17 to reciprocate linearly on the anti-rotation rod 15 through the swing block. When the slider 17 reciprocates linearly, it drives the brush plate 20 fixed on the slider 17 to clean the filter plate 5.

[0092] S3: When the slider 17 drives the brush plate 20 to reciprocate linearly, the driven rack 28 drives the first cleaning plate 26 to move closer to the filter plate 5, and the cleaning block 27 cleans the gaps of the brush bristles 21.

[0093] S4: During the up-and-down movement of the brush plate 20, it will also squeeze or extend the bellows tube 38, and the water flow will be sprayed from the spray hole 36 onto the filter plate 5 to clean the impurities attached to the filter plate 5.

[0094] S5: When the brush plate 20 moves toward the drain pipe 9, it squeezes the valve 47. The valve 47 opens under the pressure of the brush plate 20, and water sprays out from several secondary pipes 46 to clean the brush plate 20.

[0095] Working principle:

[0096] First, the operator uses screws to connect the float 1 to the filter screen plate 2, then uses screws to connect the assembled float 1 to the filter screen plate 2, and then fixes the filter screen base plate 3 to the bottom of several turbine boxes 10, so that several filter screen plates 2 and filter screen base plates 3 together form a screen box. Then, several water inlet pipes 8 are connected to the water pump. Each water inlet pipe 8 is connected to a water pump, or several water inlet pipes 8 can be connected to a water pump.

[0097] When the water pump is turned on, the water flows through the inlet pipe 8 and the turbine box 10, and is discharged through the end of the drain pipe 9. The water jet from the drain pipe 9 impacts the blades 42 on the fixed ring 41. The fixed ring 41 rotates under the drive of the blades 42, and the brush rod 40 on the fixed ring 41 cleans the filter screen base plate 3.

[0098] When the brush rod 40 contacts the lever 44 on the chip removal plate 43, the brush rod 40 drives the chip removal plate 43 to rotate at a certain angle through the lever 44, so that the impurities accumulated on the filter screen bottom plate 3 are discharged through the chip removal plate 43. When the lever 44 disengages from the brush rod 40, the chip removal plate 43 is reset under the action of the reset spring 45.

[0099] When water flows through the turbine box 10, the water flow drives the turbine blades 12 in the turbine box 10 to rotate. The rotation of the turbine disk drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the bidirectional screw 13 in the sliding box 6 to rotate. The bidirectional screw 13 drives the slider 17 to reciprocate linearly on the anti-rotation rod 15 through the swing block. When the slider 17 reciprocates linearly, it drives the brush plate 20 fixedly set on the slider 17 to clean the filter plate 5.

[0100] When the slider 17 drives the brush plate 20 to reciprocate linearly, the push rod 22 on the brush plate 20 will intermittently cooperate with the wedge block 24. When the wedge block 24 cooperates with the push rod 22, the push rod 22 drives the brush plate 20 to move away from the filter plate 5 under the squeezing of the wedge block 24. The active rack 30 on the brush plate 20 drives the slider 17 and the gear 29 on the guide block 19 to rotate. The rotation of the gear 29 drives the first cleaning plate 26 to move closer to the filter plate 5 through the driven rack 28. The cleaning block 27 cleans the gaps of the bristles 21.

[0101] When gear 29 rotates, it drives cam 34 to rotate synchronously. When cam 34 rotates, the second cleaning plate 32 is driven to move closer to the first cleaning plate 26 by the elastic force of spring 33. The first cleaning plate 26 and the second cleaning plate 32 work together to clean the gaps of the bristles 21.

[0102] When the wedge 24 engages with the push rod 22, the push rod 22, under the pressure of the wedge 24, drives the brush plate 20 to move away from the filter plate 5. When the wedge 24 disengages from the push rod 22, the push rod 22, under the pressure of the compression spring 23, drives the brush plate 20 to reset and engage with the slider 17 and the guide block 19.

[0103] During the up-and-down movement of the brush plate 20, it will also squeeze or extend the accordion tube 38. The accordion tube 38 is connected to the first one-way valve 37 and the second one-way valve 39. When the brush plate 20 moves towards the first one-way valve 37, the accordion tube 38 will extend. At this time, the first one-way valve 37 will close and the second one-way valve 39 will open, and the water will fill the inside of the accordion tube 38. When the brush plate 20 moves towards the second one-way valve 39, the accordion tube 38 will be compressed. The first one-way valve 37 will open and the second one-way valve 39 will close. At this time, the water will enter the spray pipe 35 through the first one-way valve 37 and then be sprayed onto the filter plate 5 from the spray hole 36 to clean the impurities attached to the filter plate 5.

[0104] When the brush plate 20 moves toward the drain pipe 9, it squeezes the valve 47. When the valve 47 is opened by the squeeze of the brush plate 20, water is sprayed out from several secondary pipes 46 to clean the brush plate 20.

[0105] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
