Description

Technical Field

[0001] This invention relates to the field of water quality oxygen supply and purification technology, specifically a water purification device and its usage method. Background Technology

[0002] Algae cultivation refers to the production process of algae reproduction and growth under artificial control. Depending on the cultivation method, it is divided into fixed, semi-floating and fully floating types. Algae cultivation requires extremely high water quality, and the water needs to maintain extremely high oxygen content and activity.

[0003] The prior art discloses a Chinese patent with application number CN202210842769.2, which discloses an efficient cultivation method for Daphnia foetida for water purification. The method uses water flow generated by an impeller aerator to guide the Daphnia foetida through a filter screen under the guidance of LED lights. Some fallen leaves, floating submerged plants, and large aquatic insects attached to the water are blocked outside the net cage, and the Daphnia foetida in the water gather in the net cage.

[0004] Although the above-mentioned device can efficiently cultivate algae, it requires continuous oxygenation of the water to ensure the quality of the algae during cultivation. Furthermore, the outer frame used for cultivation is constantly immersed in water, and bacteria on the outside of the algae can easily clog the frame, preventing the algae inside from receiving sufficient oxygen and thus affecting the quality of the algae. Summary of the Invention

[0005] The purpose of this invention is to provide a water purification device and its usage method to solve the problems mentioned in the background art of continuously injecting oxygen into water.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A water purification device includes a float plate, a placement component fixedly installed on the lower end face of the float plate, a cultivation frame for cultivating algae in the middle of the placement component, a pushing component connected to the placement component on one side of the cultivation frame, an oxygen generating unit rotatably connected to the float plate on the outside of the placement component, a solar panel for supplying energy to the oxygen generating unit and the pushing component respectively on the top of the float plate, and cleaning components for cleaning the cultivation frame on both the front and rear sides of the placement component.

[0008] Furthermore, the placement component includes two sets of symmetrically arranged fixing bars, with a central plate installed between each set of fixing bars. A mounting frame for engaging and sliding the culture frame is slidably arranged between the two central plates. The pushing component includes a pushing plate slidably installed on one side of the mounting frame. Springs fixed to the mounting frame are provided on both sides of the culture frame. A squeezing wheel rotatably connected to the central plate is in contact with one side of the pushing plate. A first motor is fixedly installed on the float plate. A drive rod is fixedly installed at the output end of the first motor. The drive rod is fixedly connected to the squeezing wheel. A moving groove is opened on one side of the central plate. A moving part fixed to the mounting frame slides in the moving groove.

[0009] Furthermore, the cleaning component includes a frame mounted on the front and rear sides of the mounting frame, with adjustment grooves on both sides of the frame. Two brush plates arranged vertically are slidably mounted in the adjustment grooves on both sides. A central rod is rotatably mounted at the center of the mounting frame. A push-pull plate that is hinged to the two brush plates is fixedly mounted on the side of the central rod near the culture frame. A blade is provided at the end of the central rod away from the push-pull plate.

[0010] Furthermore, the oxygen generation unit includes a rotating frame connected to the lower end face of the float plate via an electric slider. The rotating frame is equipped with two symmetrically arranged electric push plates. A vertical frame is fixedly installed at the telescopic end of the electric push plate. A trough is opened on the side of the vertical frame near the culture frame. A displacement plate is slidably installed in the trough. Multiple air injection pipes for supplying oxygen to the water outside the culture frame are fixedly installed on one side of the displacement plate.

[0011] Furthermore, the oxygen generating unit also includes a support plate located between two vertical frames and slidably connected by an electric slider. A second motor is fixedly installed in the middle of the upper surface of the support plate, and a cam is fixedly installed at the output end of the second motor. A through groove is opened on the side of the vertical frame away from the displacement plate, and an extension rod fixed to the vertical frame is slidably installed in the through groove. A control plate is provided below the cam to fit the extension rod.

[0012] Furthermore, the vertical frame is set in two sections, with a cylinder shared between the two sections, and a spring installed between the lower section of the vertical frame and the displacement plate.

[0013] Furthermore, rectangular slots are symmetrically provided on both sides of the upper surface of the float plate. Rectangular blocks are slidably installed in the rectangular slots via electric sliders. Electric push rods are fixedly installed on the upper surface of the rectangular blocks. Air storage boxes are rotatably installed on the telescopic ends of the electric push rods on both sides. Two symmetrical air supply pipes are installed on one side of the air storage box. The ends of the two air supply pipes away from the air storage box are respectively connected to the corresponding displacement plates.

[0014] Furthermore, a rotating shaft is rotatably mounted on one side of the upper surface of the float plate, and pulleys are fixedly mounted on both the rotating shaft and the drive rod. A belt is provided between the pulleys. A rotating component is fixedly mounted on the upper end of the rotating shaft. An air cylinder is fixedly mounted on the upper surface of the float plate. A piston rod is slidably mounted in the middle of the air cylinder. An arc-shaped groove is opened on one side of the piston rod. The round rod at one end of the rotating component slides in the arc-shaped groove. A transmission pipe is connected between one end of the air cylinder and the air storage tank.

[0015] Furthermore, a one-way valve is installed inside the air injection pipe.

[0016] Another object of the present invention is to provide a water purification method, comprising the following steps:

[0017] S1: Enhances water activity:

[0018] Place the desired algae into the cultivation frame, then snap the two grooves at the bottom of the cultivation frame into the mounting frame. Place the float plate in the water, turn on the first motor to drive the drive rod to rotate. When the drive rod rotates, it pushes the push plate through the extrusion wheel. As the push plate slides, it intermittently pushes the cultivation frame on the mounting frame, thereby impacting the left and right sides of the cultivation frame with the water. This cleans the sides of the cultivation frame and prevents dirt from clogging the outside of the frame during algae cultivation. The impact with the water increases the activity in the water, thereby improving the water quality and ensuring that the algae are cultivated in water with sufficient oxygen content.

[0019] S2: Water oxygenation:

[0020] While the rotation of the drive rod enhances water activity, the oxygen generation unit also enables the air injection pipe to continuously supply oxygen to the water. In conjunction with the displacement plate sliding up and down on the vertical frame, the rotating frame drives the displacement plate to rotate circumferentially along the outside of the culture frame, thereby enabling radial and axial oxygen supply to the outside of multiple culture frames, thus ensuring uniform oxygen content in the water outside the culture frames.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention features multiple cultivation frames, each individually placed on a corresponding mounting rack, enabling the cultivation of different types of algae. Each cultivation frame can be independently placed and removed. Compared to existing devices, this invention allows for the independent cultivation of multiple types of algae and enables rapid placement and removal of cultivation frames without the need for disassembling and reassembling multiple frames. The push-pull component allows the cultivation frames to be continuously moved while cultivating algae in water. This movement causes water flow to impact the frame, preventing dirt buildup and blockages caused by prolonged submersion. Furthermore, the impact enhances water activity, improving the water quality for optimal algae cultivation. An oxygen-generating unit continuously injects oxygen into the water, ensuring sufficient oxygen for high-quality algae cultivation. The solar panel absorbs light energy to supply the driving energy required for the oxygen-generating unit and the push-pull component.

[0023] 2. In this invention, when the culture frame slides left and right on the mounting frame, both sides of the culture frame can be cleaned by impact with water. At this time, the water flow on the left and right sides of the culture frame impacts the blades, causing the blades to rotate after being impacted. The rotation of the blades drives the central rod to rotate, and the rotation of the central rod synchronously drives the push-pull plate to rotate. This causes the upper and lower brush plates to constantly move closer and further away from each other, thus performing up-and-down brushing and cleaning on the front and back sides of the culture frame. In addition, in conjunction with the left and right sliding of the culture frame, it can also perform uniform left and right brushing on the front and back sides of the culture frame, thereby avoiding the situation where the water flow cannot directly impact the front and back sides of the culture frame, which would lead to dirt clogging on the front and back sides of the culture frame.

[0024] 3. This invention uses an electric slider to drive a rotating frame to rotate circumferentially around the outside of the culture frame, thereby enabling the oxygen generation unit to uniformly supply oxygen to the outside of the supply frame in a circumferential manner. By supplying oxygen to the water in a circumferential manner, the oxygen quality of the water outside the supply frame can be replenished to the maximum extent. A second motor drives a cam to rotate. When the cam rotates, it intermittently squeezes the control plate, causing the control plate to slide up and down. When the control plate slides up and down, the displacement plate inside the vertical frame can move up and down through the extension rod. When the displacement plate moves up and down, the air injection pipe slides up and down to inject oxygen into the outside of the culture frame. In conjunction with the rotation of the rotating frame, sufficient oxygen can be supplied to the outside of multiple culture frames.

[0025] 4. This invention uses an electric slider to drive a rectangular block to slide within a rectangular groove, thereby moving the electric push rod and the air storage tank on a float plate. This facilitates the placement and removal of the culture frame below through the opening in the middle of the float plate, without needing to remove the entire device from the water. The pulley and belt design allows the drive rod to rotate, which in turn drives the rotating component to rotate. When the rotating component rotates, it continuously compresses the air cylinder through the piston rod, thereby replenishing the air storage tank with oxygen. Attached Figure Description

[0039] 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.

[0040] As attached Figure 1-10 As shown, a water purification device includes a float plate 1, a placement component fixedly installed on the lower end face of the float plate 1, a cultivation frame 37 for cultivating algae in the middle of the placement component, a pushing component connected to the placement component on one side of the cultivation frame 37, an oxygen generating unit rotatably connected to the float plate 1 on the outside of the placement component, a solar panel 2 for supplying energy to the oxygen generating unit and the pushing component respectively on the top of the float plate 1, and cleaning components for cleaning the cultivation frame 37 on both the front and rear sides of the placement component.

[0041] like Figure 5As shown, multiple cultivation frames 37 are individually placed on corresponding mounting racks 31, enabling the cultivation of different types of algae. Each cultivation frame 37 can be independently placed and removed. Compared to existing devices, this invention allows for the independent storage and cultivation of multiple types of algae, and enables rapid placement and removal of the cultivation frames 37 without the need for disassembling and reassembling multiple frames. Furthermore, the push-pull mechanism allows the cultivation frames 37 to be continuously moved while cultivating algae in water. This movement causes water flow to impact the frame, preventing scale buildup and blockages caused by prolonged submersion. The impact also enhances water activity, improving the water quality for optimal algae cultivation. The oxygenation unit continuously injects oxygen into the water, ensuring sufficient oxygen content for high-quality algae cultivation. Figure 1 As shown, the solar panel 2 absorbs light energy and supplies the driving energy required by the oxygen generation unit and the push assembly.

[0042] like Figure 5 and Figure 6 As shown, the placement component includes two sets of symmetrically arranged fixing strips 3, with a central plate 30 installed between each set of fixing strips 3. A mounting frame 31 for engaging and sliding the culture frame 37 is slidably arranged between the two central plates 30. The pushing component includes a pushing plate 36 slidably installed on one side of the mounting frame 31. Springs fixed to the mounting frame 31 are provided on both sides of the culture frame 37. A squeezing wheel 35 rotatably connected to the central plate 30 is in contact with one side of the pushing plate 36. A first motor 33 is fixedly installed on the float plate 1. A drive rod 34 is fixedly installed at the output end of the first motor 33. The drive rod 34 is fixedly connected to the squeezing wheel 35. A moving groove 301 is opened on one side of the central plate 30. A moving part 302 fixed to the mounting frame 31 slides in the moving groove 301.

[0043] Slide any one of the mounting brackets 31 back and forth. At this time, the moving part 302 also slides in the moving groove 301, which makes it easy to pick up and put the culture frame 37 on the mounting bracket 31. The spring setting can push the push plate 36 to release the push plate 36. The spring setting can squeeze the sliding rod of the culture frame 37, so as to cooperate with the push plate 36 to slide the culture frame 37 back and forth, so as to generate impact in the water.

[0044] like Figure 5 , Figure 7 and Figure 8As shown, the cleaning component further includes a frame 38 installed on the front and rear sides of the mounting frame 31. The frame 38 has adjustment grooves 381 on both sides. Two brush plates 382 arranged vertically are slidably installed in the adjustment grooves 381 on both sides. A central rod 383 is rotatably installed at the center of the mounting frame 31. A push-pull plate 385 that is hinged to the two brush plates 382 is fixedly installed on the side of the central rod 383 near the culture frame 37. A blade 384 is provided at the end of the central rod 383 away from the push-pull plate 385.

[0045] When the culture frame 37 slides left and right on the mounting frame 31, both sides of the culture frame 37 are cleaned by the impact of water. At this time, the water flow on both sides of the culture frame 37 impacts the blades 384, causing the blades 384 to rotate. When the blades 384 rotate, they drive the central rod 383 to rotate, which in turn drives the push-pull plate 385 to rotate. This causes the upper and lower brush plates 382 to move closer and further away from each other, thus cleaning the front and back sides of the culture frame 37 in an up-and-down motion. In addition, the left and right sliding of the culture frame 37 also allows for a uniform left and right brushing of the front and back sides, preventing the water flow from failing to directly impact the front and back sides of the culture frame 37 and thus avoiding the blockage of dirt on the front and back sides of the culture frame 37. The rotation of the blades 384 can also be driven by a motor.

[0046] like Figures 2 to 4 and Figure 9 As shown, the oxygen generation unit further includes a float plate 1 with a rotating frame 40 rotatably connected to its lower end. The rotating frame 40 is equipped with two symmetrically arranged electric push plates 41. A vertical frame 42 is fixedly installed at the telescopic end of each electric push plate 41. A groove is provided on the side of the vertical frame 42 near the culture frame 37, and a displacement plate 421 is slidably installed within the groove. Multiple air injection pipes 422 for supplying oxygen to the water outside the culture frame 37 are fixedly installed on one side of the displacement plate 421. The rotational installation method of the rotating frame 40 is existing technology; for example, it uses a slider to limit sliding within an annular guide rail, and can be driven by a motor and gear ring.

[0047] By driving the rotating frame 40 to rotate circumferentially around the outside of the culture frame 37, the oxygen generation unit can provide uniform oxygen supply to the outside of the culture frame 37 in a circumferential manner. By providing oxygen supply to the water in a circumferential manner, the oxygen quality of the water outside the culture frame 37 can be replenished evenly to the greatest extent. The second motor 427 is turned on to drive the cam 428 to rotate. When the cam 428 rotates, it intermittently squeezes the control plate 425, which can slide up and down. When the control plate 425 slides up and down, the extension rod 424 can move the displacement plate 421 in the vertical frame 42 up and down. When the displacement plate 421 moves up and down, the air injection pipe 422 can slide up and down to inject oxygen into the outside of the culture frame 37. With the rotation of the rotating frame 40, the oxygen supply to the outside of multiple culture frames 37 can be fully provided.

[0048] Furthermore, the oxygen generating unit also includes a support plate 426 located between the two vertical frames 42 and slidably connected by an electric slider. A second motor 427 is fixedly installed in the middle of the upper surface of the support plate 426. A cam 428 is fixedly installed at the output end of the second motor 427. A through groove is opened on the side of the vertical frame 42 away from the displacement plate 421. An extension rod 424 fixed to the vertical frame 42 is slidably installed in the through groove. A control plate 425 is provided below the cam 428 to fit the extension rod 424.

[0049] Furthermore, the vertical frame 42 is configured in two sections, with a cylinder 423 shared between the two sections of the vertical frame 42, and a spring shared between the lower section of the vertical frame 42 and the displacement plate 421.

[0050] like Figures 2 to 4 and Figure 9 As shown, further, rectangular grooves are symmetrically opened on both sides of the upper end face of the float plate 1. A rectangular block 11 is slidably installed in the rectangular groove through an electric slider. An electric push rod 13 is fixedly installed on the upper end face of the rectangular block 11. An air storage box 436 is rotatably installed on the telescopic ends of the electric push rods 13 on both sides. Two symmetrical air supply pipes 437 are installed on one side of the air storage box 436. The ends of the two air supply pipes 437 away from the air storage box 436 are respectively connected to the corresponding displacement plates 421.

[0051] The electric slider opens and drives the rectangular block 11 to slide in the rectangular groove, thereby moving the electric push rod 13 and the air storage box 436 on the float plate 1. This makes it easy to pick up and put down the culture frame 37 below through the opening in the middle of the float plate 1 without having to remove the entire device from the water.

[0052] like Figure 4 and Figure 6As shown, further, a rotating shaft 43 is rotatably installed on one side of the upper end face of the float plate 1. Pulleys are fixedly installed on both the rotating shaft 43 and the drive rod 34, and a belt is provided between the pulleys. A rotating component 431 is fixedly installed on the upper end of the rotating shaft 43. An air cylinder 432 is fixedly installed on the upper end face of the float plate 1. A piston rod 433 is slidably installed in the middle of the air cylinder 432. An arc-shaped groove 434 is opened on one side of the piston rod 433. The round rod at one end of the rotating component 431 slides in the arc-shaped groove 434. A transmission pipe 435 is connected between one end of the air cylinder 432 and the air storage box 436.

[0053] The pulleys and belts enable the drive rod 34 to rotate, which in turn drives the rotating component 431 to rotate. As the rotating component 431 rotates, it continuously compresses the air cylinder 432 via the piston rod 433, thereby replenishing the oxygen supply to the air storage tank 436. It should be understood that the specific structure and principle of the piston rod 433 and the air cylinder 432 are existing technologies. Specifically, when the piston rod 433 moves outward from the air cylinder 432, it allows air to enter the air cylinder 432; when the piston rod 433 moves inward from the air cylinder 432, it forces the gas inside the air cylinder 432 into the air storage tank 436.

[0054] like Figure 9 As shown, a one-way valve is further provided inside the air injection pipe 422.

[0055] Another object of the present invention is to provide a water purification method, comprising the following steps:

[0056] S1: Enhances water activity:

[0057] Place the desired algae into the culture frame 37, then engage the two grooves at the bottom of the culture frame 37 with the mounting frame 31. Place the float plate 1 in the water. Turn on the first motor 33 to drive the drive rod 34 to rotate. When the drive rod 34 rotates, it pushes the push plate 36 to slide through the extrusion wheel 35. When the push plate 36 slides, it intermittently pushes the culture frame 37 on the mounting frame 31, thereby impacting the left and right sides of the culture frame 37 with the water. This cleans the sides of the culture frame 37 and prevents dirt from clogging the outside of the frame during algae cultivation. The impact with the water increases the activity in the water, thereby improving the water quality and ensuring that the algae are cultivated in water with sufficient oxygen content.

[0058] S2: Water oxygenation:

[0059] While the rotation of the drive rod 34 enhances water activity, the oxygen generation unit also enables the air injection pipe 422 to continuously supply oxygen to the water. In conjunction with the displacement plate 421 sliding up and down on the vertical frame 42, the rotating frame 40 drives the displacement plate 421 to rotate circumferentially along the outside of the culture frame 37, thereby enabling radial and axial oxygen supply to the outside of multiple culture frames 37, thus ensuring uniform oxygen content in the water outside the culture frame 37.

[0060] Multiple cultivation frames 37 are provided and placed individually on corresponding mounting racks 31, enabling the cultivation of different types of algae. Each cultivation frame 37 can be independently placed and removed. Compared to existing devices, this invention allows for the independent storage and cultivation of multiple types of algae, and enables rapid placement and removal of cultivation frames 37 without the need for disassembling and reassembling multiple frames. The push-pull mechanism allows the cultivation frames 37 to be continuously moved while cultivating algae in water. During this movement, the water flow impacts the frame of the cultivation frames 37, preventing dirt buildup and blockage caused by prolonged submersion. Furthermore, the impact enhances water activity, allowing for better aquatic cultivation of the algae within the frames. The oxygen-generating unit continuously injects oxygen into the water, ensuring sufficient oxygen content for optimal algae cultivation. The solar panel 2 absorbs light energy to supply the driving energy required by the oxygen-generating unit and the push-pull mechanism.

[0061] Slide any one of the mounting brackets 31 back and forth. At this time, the moving part 302 also slides in the moving groove 301, which makes it easy to pick up and put the culture frame 37 on the mounting bracket 31. When the push plate 36 is released by the spring, the culture frame 37 can be squeezed by the spring to slide the sliding rod, so as to slide the culture frame 37 back and forth in conjunction with the push plate 36 to generate impact in the water.

[0062] When the culture frame 37 slides left and right on the mounting frame 31, both sides of the culture frame 37 can be cleaned by the impact of water. At this time, the water flow on the left and right sides of the culture frame 37 impacts the blades 384. After being impacted, the blades 384 rotate. When the blades 384 rotate, they drive the central rod 383 to rotate. When the central rod 383 rotates, it drives the push-pull plate 385 to rotate simultaneously. This causes the upper and lower brush plates 382 to continuously move closer and further away from each other, thereby cleaning the front and back sides of the culture frame 37 by brushing them up and down. In addition, with the left and right sliding of the culture frame 37, the front and back sides of the culture frame 37 can also be cleaned evenly by brushing them left and right. This avoids the situation where the water flow cannot directly impact the front and back sides of the culture frame 37, which would lead to dirt clogging on the front and back sides of the culture frame 37.

[0063] The electric slider opens and drives the rotating frame 40 to rotate circumferentially around the outside of the culture frame 37, thereby enabling the oxygen generation unit to uniformly supply oxygen to the outside of the supply frame 37 in a circumferential manner. By supplying oxygen to the water in a circumferential manner, the oxygen quality of the water outside the supply frame 37 can be replenished to the maximum extent. The second motor 427 opens and drives the cam 428 to rotate. When the cam 428 rotates, it intermittently squeezes the control plate 425, which allows the control plate 425 to slide up and down. When the control plate 425 slides up and down, the extension rod 424 can move the displacement plate 421 inside the vertical frame 42 up and down. When the displacement plate 421 moves up and down, the air injection pipe 422 slides up and down to inject oxygen into the outside of the culture frame 37. With the rotation of the rotating frame 40, the oxygen supply to the outside of multiple culture frames 37 can be fully provided.

[0064] The electric slider opens and drives the rectangular block 11 to slide within the rectangular groove, thereby moving the electric push rod 13 and the air storage tank 436 on the float plate 1. This facilitates the placement and removal of the culture frame 37 below through the opening in the middle of the float plate 1, without having to remove the entire device from the water. The pulley and belt configuration allows the drive rod 34 to rotate, which in turn drives the rotating component 431 to rotate. When the rotating component 431 rotates, it continuously compresses the air cylinder 432 through the piston rod 433, thereby replenishing the oxygen in the air storage tank 436.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

7. A method of using a water purification device, applied to the water purification device according to any one of claims 3-6, characterized in that, Includes the following steps: S1: Enhances water activity: Place the algae to be cultivated in the cultivation frame (37), and then attach the two grooves at the bottom of the cultivation frame (37) to the mounting frame (31) respectively. Place the float plate (1) in the water. Turn on the first motor (33) to drive the drive rod (34) to rotate. When the drive rod (34) rotates, it pushes the push plate (36) to slide through the extrusion wheel (35). When the push plate (36) slides, it intermittently pushes the cultivation frame (37) on the mounting frame (31), thereby impacting the left and right sides of the cultivation frame (37) with the water, thus cleaning the sides of the cultivation frame (37) and preventing dirt from clogging the outside of the frame when the algae are cultivated. When impacting the water, it increases the activity in the water to improve the water quality, so that the algae can be cultivated in water with sufficient oxygen content. S2: Water oxygenation: While the drive rod (34) rotates to enhance water activity, the oxygen generation unit also enables the air injection pipe (422) to continuously supply oxygen to the water. In addition, the displacement plate (421) slides up and down on the vertical frame (42). The rotating frame (40) drives the displacement plate (421) to rotate circumferentially along the outside of the culture frame (37), thereby enabling radial and axial oxygen supply to the outside of multiple culture frames (37), thus ensuring uniform oxygen content in the water outside the culture frame (37).
