[0002] In the field of aquaculture, water purification is crucial to ensuring the healthy growth of farmed organisms.

[0003] Currently, most existing aquaculture water purification devices are fixed in place, which limits the purification range and easily creates dead zones. They also usually rely on water pumps to directly draw water, resulting in low efficiency in actively collecting surface floating dirt. In addition, these devices have a single filtration level, which can often only intercept large particulate impurities and is difficult to degrade soluble toxins such as ammonia nitrogen and nitrite, resulting in incomplete purification.

[0016] This application provides a water purification device for aquaculture ponds. The device is placed in the pond and floats on the water surface via a suspending mechanism. A flow-guiding filter mechanism is located on the upper inner side of the shell, near the opening. A flow-guiding drive mechanism drives the flow-guiding filter mechanism to slide up and down along the inner wall of the shell, causing it to extend above and then return below the water surface, thus pressing water into the filter mechanism. Driven by the flow-guiding drive mechanism, the flow-guiding filter mechanism repeatedly moves up and down, continuously pressing water into it.

A centrifugal feeding mechanism is installed at the top of symmetrical suspended tanks, combining flocculant delivery with mobile operation. The device can evenly distribute material while moving, first promoting the flocculation and sedimentation of fine particles, then, combined with mobile filtration, significantly enhancing the physical filtration effect and purification efficiency. The entire process is completed seamlessly. The purification mechanism internally integrates filter sponges, biological filter plates, and activated carbon plates in a series. This three-stage "physical-biological-chemical" purification strategy not only removes solid impurities but also deeply addresses dissolved pollutants, resulting in a higher degree of purification for the discharged water. Four suspended tanks are symmetrically arranged on the four sides of the shell via folding rods, forming a stable horizontal floating platform. The flow-guiding drive mechanism also employs a symmetrical layout for synchronized force application. This balanced design ensures the device remains stable during lifting, lowering, dispensing, and movement, preventing tilting or water ingress failure. This application's device effectively improves upon existing purification devices, which are mostly fixed-point installations, resulting in limited purification range; and existing purification devices, which mostly rely on direct water pumping, have a low capacity for collecting surface floating debris.

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0022] The following reference Figures 1 to 9 This application describes a water purification device for aquaculture ponds provided according to some embodiments.

[0023] Example A water purification device for aquaculture ponds includes a shell 1, a suspension mechanism 2, a flow guiding and filtering mechanism 3, a flow guiding and driving mechanism 4, and a purification mechanism 5. The shell 1 is a hollow square structure with an open top. The suspension mechanism 2 is arranged around the outside of the shell 1, allowing the water purification device to suspend in the water. The flow guiding and filtering mechanism 3 is slidably disposed on the upper inner side of the shell 1, allowing it to move up and down along the inner wall of the shell 1. The flow guiding and filtering mechanism 4 is disposed between the inner wall of the shell 1 and the flow guiding and filtering mechanism 3, driving the flow guiding and filtering mechanism 3 to move up and down. The purification mechanism 5 is disposed at the bottom of the flow guiding and filtering mechanism 3, with its side fixedly connected to the inner wall of the shell 1. The purification mechanism 5 is connected to the flow guiding and filtering mechanism 3.

[0024] According to this embodiment, a water purification device for an aquaculture pond is placed in the aquaculture pond to be purified. The entire device floats on the water surface through a suspension mechanism 2. A flow-guiding filter mechanism 3 is located on the upper inner side of the shell 1, near the opening of the shell. A flow-guiding drive mechanism 4 drives the flow-guiding filter mechanism 3 to slide up and down along the inner wall of the shell 1, causing the flow-guiding filter mechanism 3 to extend out of the water surface and then return below the water surface, thereby pressing water into the flow-guiding filter mechanism 3. Driven by the flow-guiding drive mechanism 4, the flow-guiding filter mechanism 3 can repeatedly move up and down, thereby continuously pressing water into the flow-guiding filter mechanism 3. After entering the flow-guiding filter mechanism 3, the water undergoes initial filtration. After initial filtration, the water undergoes fine filtration through a purification mechanism 5. After purification, the water is discharged back into the aquaculture pond. Thus, the device can continuously purify the water, gradually filtering and purifying the water in the aquaculture pond, so that the water in the aquaculture pond is finally purified to meet the requirements.

[0025] As an optional implementation of this embodiment, the suspension mechanism 2 further includes four folding rods 22 and four suspension buckets 21; wherein, one end of each of the four folding rods 22 is fixedly connected to one of the four outer walls of the housing 1; the four suspension buckets 21 are respectively suspended above the four outer walls of the housing 1; the four suspension buckets 21 correspond one-to-one with the four folding rods 22; the four suspension buckets 21 are respectively fixedly connected to the end of their respective folding rods 22 away from the housing 1; any two suspension buckets 21 suspended above the two opposite outer walls of the housing 1 are arranged symmetrically.

[0026] It should be noted that the four folding rods 22 are fixedly connected to the four outer walls of the shell 1 by one end; the four suspension buckets 21 are suspended above the four outer walls of the shell 1, and the ends of the four folding rods 22 away from the shell 1 are connected to a suspension bucket 21 respectively; in this way, a suspension bucket 21 is set in each of the four horizontal directions of the shell 1, so that the opening at the top of the shell 1 is located near the horizontal plane of the water body; at the same time, it can increase the stability of the device floating in the water body; and any two suspension buckets 21 suspended above the two opposite outer walls of the shell 1 are symmetrically arranged, that is, the suspension buckets 21 on the left and right sides are symmetrical to each other; the suspension buckets 21 on the front and back sides are symmetrical to each other; such a symmetrical design can increase the balance of the device floating in the water body; thus, it can better carry out purification operations.

[0027] As an optional implementation of this embodiment, the flow guiding and filtering mechanism 3 further includes a flow guiding bucket 31, an installation cylinder 32, a filter screen 33, a first water pump 34, and a connecting pipe 35; wherein, the flow guiding bucket 31 is disposed at the opening at the top of the housing 1; a slider is provided on each of the two opposite outer side walls of the flow guiding bucket 31, and a vertical groove is provided on each of the two opposite inner side walls of the housing 1; the two sliders are slidably disposed in the two vertical grooves; the installation cylinder 32 is disposed at the bottom of the flow guiding bucket 31; the top of the installation cylinder 32 is fixedly connected to the bottom of the flow guiding bucket 31; the filter screen 33 is detachably disposed in the flow guiding bucket 31, and the bottom of the filter screen 33 hangs down into the installation cylinder 32; the first water pump 34 is disposed in the installation cylinder 32; one end of the connecting pipe 35 is connected to the outlet of the first water pump 34, and the other end passes through the installation cylinder 32 and the top of the purification mechanism 5, and extends into the purification mechanism 5.

[0028] It should be noted that the guide bucket 31 is located at the opening at the top of the housing 1, ensuring that the top of the guide bucket 31 is always near the horizontal plane. Each of the two outer sidewalls of the guide bucket 31 is equipped with a slider, and each of the two inner sidewalls of the housing 1 is equipped with a vertical groove. The two sliders are slidably positioned within the two vertical grooves, allowing the guide bucket 31 to move up and down along the vertical grooves, thereby driving the entire guide filter mechanism 3 to move up and down. During the up-and-down movement of the guide bucket 31, after the top of the guide bucket 31 extends to the horizontal plane... The water level immediately drops below the water surface, and air pressure forces the water into the guide bucket 31. After entering the guide bucket 31, larger debris and dirt are blocked by the filter screen 33 inside the installation cylinder 32. The water and smaller dirt are pumped by the first water pump 34 to the connecting pipe 35 and then into the purification mechanism 5 for further filtration and purification. The filter screen 33 is detachably installed inside the guide bucket 31, which makes it easy to remove the filter screen 33. Through the reciprocating up and down movement of the guide bucket 31, water can be continuously forced into the device, thereby continuously purifying the water.

[0029] As an optional implementation of this embodiment, the flow guiding drive mechanism 4 includes a first drive component 41 and a second drive component 42; the first drive component 41 and the second drive component 42 are symmetrically arranged on two opposite inner sidewalls of the housing 1; one side of the first drive component 41 is fixedly connected to the inner sidewall of the housing 1, and the other side is rotatably connected to the side of the flow guiding bucket 31 near the first drive component 41; one side of the second drive component 42 is fixedly connected to the inner sidewall of the housing 1, and the other side is rotatably connected to the side of the flow guiding bucket 31 near the second drive component 42; the first drive component 41 and the second drive component 42 move synchronously, driving the flow guiding bucket 31 to move up and down inside the housing 1.

[0030] It should be noted that the first drive assembly 41 and the second drive assembly 42 have the same structure and are symmetrically distributed; they can synchronously push the guide bucket 31 upward or pull the guide bucket 31 downward; thereby realizing that the two sliders on the outer wall of the guide bucket 31 can synchronously slide upward or downward in the vertical groove on the inner wall of the housing; thereby realizing the up and down movement of the guide filter mechanism 3.

[0031] As an optional implementation of this embodiment, the first drive assembly 41 further includes an electric drive cylinder 411, a connecting shaft 413, and a connecting rod 414; wherein, the electric drive cylinder 411 is fixedly disposed on the inner side wall of the housing 1; a rotating ring 412 is fixedly disposed at the telescopic end of the electric drive cylinder 411; one end of the connecting shaft 413 passes through the rotating ring 412 and is rotatably connected to the rotating ring 412; one end of the connecting rod 414 is rotatably connected to the end of the connecting shaft 413 away from the rotating ring 412, and the other end is rotatably connected to the side of the guide bucket 31 close to the first drive assembly 41.

[0032] It should be noted that the electric drive cylinder 411 is arranged horizontally. When the electric drive cylinder 411 is activated, its telescopic end extends horizontally, driving the rotating ring 412 to move. One end of the connecting shaft 413 passes through the rotating ring 412 and is rotatably connected to it. Therefore, the movement of the rotating ring 412 will also drive the connecting shaft 413 to move in the direction in which the electric drive cylinder 411 extends. Furthermore, one end of the connecting rod 414 is rotatably connected to the end of the connecting shaft 413 away from the rotating ring 412, and the other end is rotatably connected to the side of the guide bucket 31 near the first drive assembly 41. Therefore, when the connecting shaft 413 moves in the direction in which the electric drive cylinder 411 extends, the connecting shaft 413 also moves horizontally. The connecting shaft 413 also drives the connecting rod 414 to move, causing the connecting rod 414 to gradually become vertical, thereby lifting the guide bucket 31 above the water surface; similarly, the electric drive cylinder 411 retracts laterally, pulling the rotating ring 412 and the connecting shaft 413 to move in the direction of motor retraction, and through the connecting shaft 413, it drives the connecting rod 414 to move, causing the connecting rod 414 to gradually become horizontal; thereby pulling the guide bucket 31 back below the water surface; the working principle of the second electric drive component 42 is the same as that of the first drive component 41, and the two move synchronously, thereby synchronously pushing the sides of the guide bucket 31 upward or pulling the sides of the guide bucket 31 downward.

[0033] As an optional implementation of this embodiment, the purification mechanism 5 further includes a purification box 51, a filter sponge 52, a biological filter plate 53, an activated carbon plate 54, a second water pump 55, and a drain pipe 56; wherein, the purification box 51 is fixedly disposed on the lower inner side of the housing 1; the top of the purification box 51 is provided with a through hole, and the connecting pipe 35 extends into the purification box 51 through the through hole at the top of the purification box 51; the filter sponge 52 is disposed inside the purification box 51; the side of the filter sponge 52 is flush with the inner wall of the purification box 51. The components are detachably connected; the biological filter plate 53 is located at the bottom of the filter sponge 52; the side of the biological filter plate 53 is detachably connected to the inner wall of the purification box 51; the activated carbon plate 54 is located at the bottom of the biological filter plate 53; the activated carbon plate 54 is detachably connected to the inner wall of the purification box 51; the second water pump 55 is located between the activated carbon plate 54 and the inner bottom wall of the purification box 51; one end of the drain pipe 56 is connected to the outlet of the second water pump, and the other end passes through the bottom of the purification box 51 and the bottom of the shell 1, and extends to the outside of the shell 1.

[0034] It should be noted that after the water is initially filtered by the flow-guiding filter mechanism 3, it enters the purification mechanism 5 and first undergoes fine physical filtration through the filter sponge 52. The water filtered by the filter sponge 52 then enters the biological filter plate 53 to decompose toxins such as ammonia nitrogen. The water after toxin decomposition finally enters the activated carbon plate 54, where the activated carbon plate 54 adsorbs odors, pigments, and some heavy metals, resulting in purified water. The purified water is then pumped by the second water pump 55 into the drain pipe 56 and returned to the aquaculture pond through the second drain pipe 56. The purification mechanism 5 achieves step-by-step, multi-stage purification of the water through the sequentially arranged physical filtration, biological filtration, and chemical filtration, namely, the filter sponge 52, the biological filter plate 53, and the activated carbon plate 54, resulting in a higher degree of purification of the water returning to the aquaculture pond.

[0035] As an optional implementation of this embodiment, the water purification device for aquaculture ponds further includes a moving mechanism 6 and two feeding mechanisms 7; wherein, the moving mechanism 6 is disposed on two opposite outer walls of the housing 1; the moving mechanism 6 includes a first propulsion component 61 and a second propulsion component 62 symmetrically disposed on two opposite outer walls of the housing 1; the moving mechanism 6 is used to drive the water purification device to move; the two feeding mechanisms 7 are respectively disposed on the top of any two symmetrically arranged suspension tanks 21; the feeding mechanisms 7 are used to add flocculant to the water in the aquaculture pond.

[0036] It should be noted that the moving mechanism 6 enables the device to move within the water. The first propulsion component 61 and the second propulsion component 62 in the moving mechanism 6 are identical and symmetrically arranged on two opposite outer walls of the housing 1. This allows control of the propulsion speeds of the first propulsion component 61 and the second propulsion component 62 to control the device's direction in the water. For example, if the first propulsion component 61 is located on the left and the second propulsion component 62 on the right, and the device needs to turn left, the propulsion speed of the first propulsion component 61 on the left is reduced; similarly, if a turn to the right is required, the propulsion speed of the second propulsion component 62 on the right is reduced. The use of only two feeding mechanisms 7 is a consideration to reduce the weight of the device while meeting the feeding requirements. Furthermore, the two feeding mechanisms 7 are respectively positioned on top of any two symmetrically arranged suspension tanks 21; for example, on top of the left and right sides of the suspension tanks 21, or on top of the front and rear sides of the suspension tanks 21. This increases stability and avoids imbalance caused by one feeding mechanism 7 being positioned on the left / right side and the other on the front / rear side. By feeding flocculant into the water through the feeding mechanisms 7, the fine suspended particles in the water are flocculated and settled before entering the purification device; this process then improves purification efficiency.

[0037] As an optional implementation of this embodiment, the first propulsion assembly 61 further includes a mounting plate 611, a guide tube 612, a dual-axis motor 613, and two propellers 614; wherein, the mounting plate 611 is fixedly disposed on the outer side wall of the housing 1 away from the second propulsion assembly 62; the guide tube 612 is a hollow structure with openings at both ends; the side of the guide tube 612 is fixedly connected to the mounting plate 611; the dual-axis motor 613 is suspended inside the guide tube 612; the two output shafts of the dual-axis motor 613 rotate in the same direction; the two propellers 614 are respectively disposed at the openings at both ends of the guide tube 612; the two propellers 614 are respectively fixedly connected to the two output shafts of the dual-axis motor 613.

[0038] It should be noted that when the first propulsion component 61 needs to operate, the dual-shaft motor 613 is activated, which simultaneously drives the two propellers 614 located at the openings at both ends of the guide tube 612 to rotate synchronously in the same direction. This pushes the water in front of the first propulsion component 61 to the rear of the first propulsion component 62 through the dual propellers, and then provides a forward thrust to the first propulsion component 61 through the reaction force. Similarly, the working principle of the second propulsion component 62 is the same as that of the first propulsion component 61. The device moves in the water body by means of the synchronous movement of the first propulsion component 61 and the second propulsion component 62. The fact that each propulsion component is driven by the dual-shaft motor 613 to rotate the two propellers 614 simultaneously is to increase the thrust of the propeller, so that the device can move in the water body at a faster speed.

[0039] As an optional implementation of this embodiment, the material spreading mechanism 7 further includes a material spreading shell 71, a rotary motor 72, a turntable 73, multiple baffles 74, and a feeding box 75; wherein, the material spreading shell 71 is a hollow structure; the bottom of the material spreading shell 71 is fixedly connected to the top of the suspension tank 21; a discharge port 711 is provided on the side of the shell 71; the rotary motor 72 is disposed on the inner bottom wall of the material spreading shell 71; the bottom of the turntable 73 is fixedly connected to the output shaft of the rotary motor 72; the outer edge of the turntable 73 contacts the inner side wall of the material spreading shell 71; the top of the turntable 73 is a conical surface with a center height and an edge bottom; the top edge of the turntable 71 and the bottom of the discharge port 711 are at the same height; multiple baffles 74 are disposed on the top of the turntable 73 in the radial direction, and the multiple baffles 74 are evenly spaced along the circumference of the turntable 73; the feeding box 75 is disposed on the top of the turntable 73; the feeding box 75 is fixedly connected to the inner side wall of the material spreading shell 71; and a discharge port is provided at the bottom of the feeding box 75.

[0040] It should be noted that flocculant is intermittently sprinkled onto the turntable 73 through the discharge port at the bottom of the feeding box 75. Since the top of the turntable 73 is a conical surface with a high center and low edges, the flocculant will move to the edge of the turntable 73 after falling onto it. The rotating motor 72 drives the turntable 73 to rotate, and the flocculant falling on the turntable 73 is rotated along with it by multiple baffles 74 arranged radially on the turntable 73. The housing has multiple sprinkling ports 711 at the same height as the turntable 73 on its side. Therefore, when the flocculant at the edge of the turntable 73 moves to the sprinkling port 711 with the turntable 73, the centrifugal force generated by the rotation will sprinkle the flocculant into the water through the sprinkling port 711.

[0041] As an optional implementation of this embodiment, the filter screen 33 and the guide hopper 31 are further connected by a snap-fit.

[0042] It should be noted that the snap-fit ​​design makes it easy to remove the filter screen 33 from the guide hopper 31 for replacement with a new filter screen 33 or to empty the waste from the filter screen 33.

[0043] The working principle of a water purification device for aquaculture ponds according to this embodiment is as follows: The water purification device is placed in the aquaculture pond, where it floats stably via four suspended buckets 21. A rotary motor 72 in the spreading mechanism 7 rotates a turntable 73, causing the flocculant on the turntable 73 to rotate along with it, carried by multiple radially arranged baffles 74. As the flocculant moves to the spreading port 711, the centrifugal force generated by the rotation propels it into the water. Simultaneously, during the spreading process, the first propulsion component 61 in the moving mechanism 6 is controlled. The second propulsion component 62 enables movement in the water body; ensuring that the feeding process covers the entire aquaculture pond; after feeding is completed, the device is shut off; after a period of settling, the moving mechanism 6 is activated to control the device to move in the water body; the first drive component 41 and the second drive component 42 are activated simultaneously, and the first drive component 41 and the second drive component 42 push the guide bucket 31 upward, so that the top inlet of the guide bucket 31 is above the water surface; then the first drive component 41 and the second drive component 42 are controlled to pull the guide bucket 31 downward simultaneously. This causes the top inlet of the guide bucket 31 to be lower than the water surface, thus forcing water into the guide bucket 31 by air pressure. Through the repeated movement of the two drive components, the guide bucket 31 can move up and down repeatedly, continuously forcing water into it. After entering the guide bucket 31, larger debris and dirt are blocked by the filter screen 33 within the mounting cylinder 32. The water and smaller debris are then pumped by the first water pump 34 to the connecting pipe 35 and enter the purification chamber 51. After initial filtration, the water enters the purification chamber 51 and first passes through the filter sponge 5. 2. A thorough physical filtration process is performed; the water filtered by the filter sponge 52 enters the biological filter plate 53 for the decomposition of toxins such as ammonia nitrogen; the decomposed water finally enters the activated carbon plate 54, where the activated carbon plate 54 adsorbs odors, pigments, and some heavy metals; the purified water is obtained; the purified water is pumped by the second water pump 55 into the drain pipe 56, and then returned to the aquaculture pond through the second drain pipe 56; this method of filtration and purification while moving the water can significantly improve the purification efficiency of the aquaculture pond water.

[0044] According to this embodiment, a water purification device for aquaculture ponds utilizes a flow-guiding drive mechanism to drive a flow-guiding bucket to move up and down repeatedly, periodically exposing and submerging the inlet at the top of the bucket. Water is actively forced into the flow-guiding bucket through air pressure difference. This non-pump-suction active water collection method has a stronger and more efficient ability to collect surface water and floating debris. The device integrates a moving mechanism consisting of a dual-shaft motor and dual propellers; through differential speed control, it can move and turn freely in the water, achieving a dynamic operation mode of purification while moving, completely solving the purification dead zone problem of fixed equipment and uniformly improving the water quality of the entire pond. By setting a centrifugal feeding mechanism on the top of the symmetrical suspension tank, flocculant delivery and mobile operation are combined into one. The device can evenly distribute material while moving, first promoting the flocculation and sedimentation of fine particles, and then, combined with mobile filtration, significantly enhancing the effect of physical filtration and purification efficiency, with the entire process completed in one go. The purification mechanism internally integrates filter sponges, biological filter plates, and activated carbon plates in a series. This three-stage "physical-biological-chemical" purification strategy not only removes solid impurities but also deeply addresses dissolved pollutants, resulting in a higher level of purification for the discharged water. Four suspended tanks are symmetrically arranged on the four sides of the shell via folding rods, forming a stable horizontal floating platform. The flow-guiding drive mechanism also employs a symmetrical layout for synchronized force application. This balanced design ensures the device remains stable during lifting, filtering, dispensing, and movement, preventing tilting or water ingress failure. This embodiment effectively improves upon existing purification devices, which are mostly fixed-point installations, resulting in limited purification range, and those that rely on direct water pumping, leading to low collection capacity for surface floating debris.
