Description

Technical Field

[0001] The present invention relates to the technical field of water quality oxygen supply and purification, and specifically to a water quality purification device and its use method. Background Art

[0002] Algae cultivation refers to the production process of algae reproduction and growth under artificial control. According to different cultivation methods, it is divided into fixed type, semi-floating type, and fully floating type. Algae have extremely high requirements for water quality during cultivation, and the water quality needs to maintain extremely high oxygen content and activity.

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

[0004] Although the above device can efficiently cultivate algae, however, in order to ensure the quality of algae during cultivation, it is necessary to continuously inject oxygen into the water quality. And during algae cultivation, the outer part of the cultivation frame used for cultivation is soaked in water for a long time, and the fungi outside the algae are extremely likely to block the frame, resulting in the algae in the frame not being able to fully obtain oxygen, thereby affecting the quality of the algae. Summary of the Invention

[0005] The purpose of the present invention is to provide a water quality purification device and its use method to solve the problems raised in the above background art of continuously injecting oxygen into the water quality.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A water quality purification device includes a floating board.

[0008] Further, the cleaning component includes frames installed on the front and back sides of the mounting frame. Adjustment grooves are formed on both sides of the frames. Two vertically arranged brush plates are slidably installed in the adjustment grooves on both sides. A central rod is rotatably installed at the center of the mounting frame. A push-pull plate hinged to the two brush plates is fixedly installed on the side of the central rod close to the culture frame. A blade is provided at the end of the central rod away from the push-pull plate.

[0009] Further, the oxygen generation unit includes a rotating frame rotatably connected to the lower end surface of the floating plate through an electric slider. Two symmetrically arranged electric push plates are installed on the rotating frame. A vertical frame is fixedly installed at the telescopic end of the electric push plate. A sliding groove is formed on the side of the vertical frame close to the culture frame. A displacement plate is slidably installed in the sliding groove. A plurality of air injection pipes for supplying oxygen to the water quality outside the culture frame are fixedly installed on one side of the displacement plate.

[0010] Further, the oxygen generation unit further includes a support plate slidably connected between the two vertical frames through an electric slider. A second motor is fixedly installed in the middle of the upper end surface of the support plate. A cam is fixedly installed at the output end of the second motor. A through groove is formed on the side of the vertical frame away from the displacement plate. An extension rod fixed to the vertical frame is slid in the through groove. A control plate for sleeving the outside of the extension rod is provided below the cam.

[0011] Further, the vertical frame is of a two-section structure. A cylinder is commonly provided between the two sections of the vertical frame. A spring is commonly installed between the lower section of the vertical frame and the displacement plate.

[0012] Further, rectangular grooves are symmetrically formed on both sides of the upper end surface of the floating plate. A rectangular block is slidably installed in the rectangular grooves through an electric slider. An electric push rod is fixedly installed on the upper end surface of the rectangular block. The telescopic ends of the electric push rods on both sides are commonly rotatably installed with a gas storage tank. Two symmetrically arranged air supply pipes are installed on one side of the gas storage tank. The ends of the two air supply pipes away from the gas storage tank are respectively connected to the corresponding displacement plates.

[0013] Furthermore, a rotating shaft is rotatably installed on one side of the upper end surface of the float board. Belt pulleys are fixedly installed on both the rotating shaft and the driving rod. A belt is provided between the belt pulleys. A rotating member is fixedly installed at the upper end of the rotating shaft. An air cylinder is fixedly installed on the upper end surface of the float board. A piston rod is slidably installed in the middle of the air cylinder. An arc-shaped groove is formed on one side of the piston rod. The round rod at one end of the rotating member is slidably located in the arc-shaped groove. A transmission pipe is commonly connected between one end of the air cylinder and the air storage tank.

[0014] Furthermore, a one-way valve is provided in the air injection pipe.

[0015] Another object of the present invention is to provide a water purification method, including the following steps: S1: Enhance water activity: Place the required algae to be cultured in the culture frame. Then, respectively and correspondingly engage the two grooves at the bottom of the culture frame on the mounting frame. Place the entire float board in the water. Turn on the first motor to drive the driving rod to rotate. When the driving rod rotates, it pushes the push board to slide through the pressing wheel. When the push board slides, it intermittently pushes the culture frame on the mounting frame, so as to be able to impact the water on the left and right sides of the culture frame, thereby cleaning the two sides of the culture frame, avoiding dirt blockage on the outside of the frame during algae cultivation, and increasing the activity in the water when impacting with the water, so as to improve the water quality and enable the algae to be cultured in water with sufficient oxygen content during cultivation; S2: Inject oxygen into the water: While the driving rod rotates to enhance the water activity, the air injection pipe can continuously supply oxygen to the water through the setting of the oxygen generation unit, and cooperate with the displacement plate to slide up and down on the vertical frame. The rotating frame drives the displacement plate to rotate circumferentially along the outside of the culture frame, so as to be able to supply oxygen radially and axially to the outside of multiple culture frames, thereby ensuring uniform oxygen content in the water quality outside the culture frame.

[0016] The beneficial effects of the present invention: 1. In the present invention, multiple culture frames are provided and are individually placed on corresponding mounting frames, enabling the cultivation of different types of algae. Moreover, any culture frame can be independently taken and placed. Compared with existing devices, the present invention can store and cultivate multiple types of algae independently during algae cultivation, and can quickly take and place the culture frames without uniformly disassembling and assembling multiple culture frames. Through the setting of the pushing component, when the culture frame is cultivating algae in water, the culture frame can be continuously moved. When moving in water, the water flow impacts the frame body of the culture frame. On the one hand, it avoids the generation of dirt on the frame body due to long-term placement in water, resulting in blockage of the frame body. On the other hand, when impacting with water, it can also enhance the activity of the water, enabling the water quality to better hydroponically cultivate the algae in the culture frame. Through the setting of the oxygen generation unit, oxygen can be continuously injected into the water, enabling the water with sufficient oxygen content to provide high-quality cultivation for the algae. The solar panel supplies the driving energy required for the oxygen generation unit and the pushing component by absorbing light energy.

[0017] 2. When the culture frame slides left and right on the mounting frame in the present invention, both the left and right sides of the culture frame can be cleaned during the impact with water. At this time, the water flow on both sides of the culture frame impacts the blades during the impact. When the blades are impacted, they rotate. When the blades rotate, they drive the central rod to rotate. When the central rod rotates, it synchronously drives the push-pull plate to rotate, so that the upper and lower brush plates continuously approach and move away from each other, thereby cleaning the front and back sides of the culture frame in an up-and-down manner. And in combination with the left and right sliding of the culture frame, it can also uniformly brush the front and back sides of the culture frame in a left-and-right manner, thus avoiding the situation where the water flow cannot directly impact the front and back sides of the culture frame, resulting in dirt blockage on the front and back sides of the culture frame.

[0018] 3. In the present invention, when the electric slider is turned on, it drives the rotating frame to rotate circumferentially along the outside of the culture frame, so that the oxygen generation unit can uniformly supply oxygen to the outside of the oxygen supply frame in a circumferential manner. By supplying oxygen to the water in a circumferential manner, the oxygen in the water outside the oxygen supply frame can be supplemented to the greatest extent. When the second motor is turned on, it drives the cam to rotate. When the cam rotates, it intermittently presses the control plate, enabling the control plate to slide up and down. When the control plate slides up and down, the displacement plate in the vertical frame can be moved up and down through the extension rod. When the displacement plate moves up and down, the injection pipe can slide up and down to inject oxygen to the outside of the culture frame. In combination with the rotation of the rotating frame, sufficient oxygen can be supplied to the outside of multiple culture frames.

[0019] 4. In the present invention, the electric slider is activated to drive the rectangular block to slide within the rectangular groove, thereby enabling the electric push rod and the gas storage tank to move on the floating plate. This facilitates the picking up and placing of the cultivation frame below through the through - opening in the middle of the floating plate, eliminating the need to remove the entire device from the water. The arrangement of the belt pulley and the belt enables the rotation of the driving rod to also drive the rotating member. When the rotating member rotates, the piston rod continuously compresses the air cylinder, thereby enabling the air cylinder to replenish oxygen into the gas storage tank.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0023] As shown in the attached Figures 1-10 figure, a water purification device includes a floating board 1. A placement component is fixedly installed on the lower end surface of the floating board 1. A culture frame 37 for cultivating algae in water is provided in the middle of the placement component. A pushing component connected to the placement component is provided on one side of the culture frame 37. An oxygen generation unit rotatably connected to the floating board 1 is provided outside the placement component. A solar panel 2 for supplying energy to the oxygen generation unit and the pushing component respectively is provided above the floating board 1. Cleaning components for cleaning the culture frame 37 are provided on both the front and back sides of the placement component.

[0024] As Figure 5As shown, there are multiple culture frames 37 which are separately placed on the corresponding mounting frames 31. They can culture different types of algae and can independently pick up and place any culture frame 37. Compared with the existing devices, the present invention can independently store and culture multiple types of algae during the algae culture process, and can quickly pick up and place the culture frame 37 without disassembling and assembling multiple culture frames 37 together. In addition, through the setting of the pushing component, when the culture frame 37 is culturing algae in water, the culture frame 37 can be continuously moved. When moving in water, the water flow impacts the frame body of the culture frame 37. On the one hand, it can prevent the culture frame 37 from being fouled and blocked after being placed in water for a long time. On the other hand, when impacted by water, it can also enhance the activity of water, enabling the water quality to better hydroponically culture the algae in the culture frame 37. Through the setting of the oxygen generation unit, oxygen can be continuously injected into the water, enabling the water with sufficient oxygen content to provide high-quality culture for the algae. As Figure 1 shown, the solar panel 2 supplies the driving energy required for the oxygen generation unit and the pushing component by absorbing light energy.

[0025] As Figure 5 and Figure 6 shown, the placing component includes two groups of symmetrically arranged fixing bars 3. A middle plate 30 is commonly installed between each group of fixing bars 3. A mounting frame 31 for clamping and sliding the culture frame 37 is slidably arranged between the middle plates 30 on both sides. 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. One side of the pushing plate 36 contacts an extrusion wheel 35 rotatably connected to the middle plate 30. A first motor 33 is fixedly installed on the floating plate 1. A driving rod 34 is fixedly installed at the output end of the first motor 33. The driving rod 34 is fixedly connected to the extrusion wheel 35. A moving groove 301 is opened on one side of the middle plate 30. A moving member 302 fixed to the mounting frame 31 slides in the moving groove 301.

[0026] Slide any one of the mounting frames 31 back and forth. At this time, the moving member 302 also slides in the moving groove 301, facilitating the picking up and placing of the culture frame 37 on the mounting frame 31. Through the setting of the spring, when the pushing force of the pushing plate 36 is cancelled, the culture frame 37 can be pushed against the sliding rod by the spring, thereby cooperating with the pushing plate 36 to slide the culture frame 37 back and forth to generate an impact in water.

[0027] As Figure 5 、 Figure 7 and Figure 8As shown, further, the cleaning component includes side frames 38 installed on the front and rear sides of the mounting frame 31. Adjustment grooves 381 are formed on both sides of the side frames 38. 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 hinged to the two brush plates 382 is fixedly installed on one side of the central rod 383 close to the culture frame 37. A blade 384 is provided at one end of the central rod 383 away from the push-pull plate 385.

[0028] When the culture frame 37 slides left and right on the mounting frame 31, both the left and right sides of the culture frame 37 can be cleaned by the impact of water. At this time, the water flow on both sides of the culture frame 37 impacts the blade 384 during the impact. At this time, the blade 384 rotates after being impacted. When the blade 384 rotates, it drives the central rod 383 to rotate. When the central rod 383 rotates, it synchronously drives the push-pull plate 385 to rotate, so that the two upper and lower brush plates 382 continuously approach and move away from each other, thereby scrubbing and cleaning the front and rear sides of the culture frame 37 up and down. And in cooperation with the left and right sliding of the culture frame 37, it can also scrub the front and rear sides of the culture frame 37 evenly left and right, thus avoiding the situation where the water flow cannot directly impact the front and rear sides of the culture frame 37, resulting in the blockage of dirt on the front and rear sides of the culture frame 37. The rotation of the blade 384 can also be driven by a motor.

[0029] As Figures 2 to 4 and Figure 9 As shown, further, the oxygen generation unit includes a rotating frame 40 rotatably connected to the lower end surface of the floating plate 1. Two symmetrically arranged electric push plates 41 are installed on the rotating frame 40. A vertical frame 42 is fixedly installed at the telescopic end of the electric push plate 41. A chute is formed on one side of the vertical frame 42 close to the culture frame 37. A displacement plate 421 is slidably installed in the chute. A plurality of air injection pipes 422 for supplying oxygen to the water quality outside the culture frame 37 are fixedly installed on one side of the displacement plate 421. Among them, the rotation installation method of the rotating frame 40 is a prior art. For example, it is limited and slid by a slider in an annular guide rail, and can be driven by the cooperation of a motor and a gear and a gear ring.

[0030] By driving the rotating frame 40 to rotate circumferentially along the outside of the culture frame 37, the oxygen generation unit can evenly supply oxygen to the outside of the oxygen supply frame 37 in a surrounding manner. By supplying oxygen to the water in a surrounding manner, the oxygen in the water can be evenly supplemented to the water quality outside the oxygen supply frame 37 to the greatest extent. When the second motor 427 is started to drive the cam 428 to rotate, the control plate 425 is intermittently pressed when the cam 428 rotates, so that the control plate 425 can slide up and down. When the control plate 425 slides up and down, the displacement plate 421 in the vertical frame 42 can be moved up and down through the extension rod 424. When the displacement plate 421 moves up and down, the injection pipe 422 can slide up and down to inject oxygen to the outside of the culture frame 37. Cooperating with the rotation of the rotating frame 40, the oxygen can be fully supplied to the outside of multiple culture frames 37.

[0031] Further, the oxygen generation unit further includes a support plate 426 slidably connected between two vertical frames 42 through an electric slider. A second motor 427 is fixedly installed in the middle of the upper end surface of the support plate 426. The output end of the second motor 427 is fixedly installed with a cam 428. A through groove is opened on one side of the vertical frame 42 away from the displacement plate 421. An extension rod 424 fixed to the vertical frame 42 is slidably arranged in the through groove. A control plate 425 sleeving the outside of the extension rod 424 is arranged below the cam 428.

[0032] Further, the vertical frame 42 is provided in a two-section manner. A cylinder 423 is jointly provided between the two sections of the vertical frame 42. A spring is jointly installed between the lower section of the vertical frame 42 and the displacement plate 421.

[0033] As Figures 2 to 4 and Figure 9 shown, further, rectangular grooves are symmetrically opened on both sides of the upper end surface 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 surface of the rectangular block 11. The telescopic ends of the electric push rods 13 on both sides are jointly rotatably installed with an air storage tank 436. Two symmetrically arranged air supply pipes 437 are installed on one side of the air storage tank 436. The ends of the two air supply pipes 437 away from the air storage tank 436 are respectively connected to the corresponding displacement plates 421.

[0034] By starting the electric slider to drive the rectangular block 11 to slide in the rectangular groove, the electric push rod 13 and the air storage tank 436 can be moved on the float plate 1, so as to facilitate the taking and placing of the lower culture frame 37 through the through hole in the middle of the float plate 1 without removing the whole device from the water.

[0035] As Figure 4 and Figure 6As shown in the figure, further, a rotating shaft 43 is rotatably installed on one side of the upper end surface of the floating board 1. Belt pulleys are fixedly installed on both the rotating shaft 43 and the driving rod 34, and a belt is provided between the belt pulleys. A rotating member 431 is fixedly installed at the upper end of the rotating shaft 43. An air cylinder 432 is fixedly installed on the upper end surface of the floating board 1. A piston rod 433 is slidably installed in the middle of the air cylinder 432. An arc-shaped groove 434 is formed on one side of the piston rod 433. The round rod at one end of the rotating member 431 is slidably located in the arc-shaped groove 434. A transmission pipe 435 is commonly connected between one end of the air cylinder 432 and the air storage tank 436.

[0036] Through the arrangement of the belt pulleys and the belt, the rotation of the driving rod 34 can drive the rotation of the rotating member 431. When the rotating member 431 rotates, it continuously compresses the air cylinder 432 through the piston rod 433, so that the air cylinder 432 replenishes oxygen into the air storage tank 436. Among them, it should be understood that the specific structure and principle of the piston rod 433 and the air cylinder 432 are both prior arts. That is, when the piston rod 433 moves towards the outside of the air cylinder 432, air can enter the air cylinder 432; when the piston rod 433 moves towards the inside of the air cylinder 432, the gas inside the air cylinder 432 can be pressed into the air tank 436.

[0037] As Figure 9 shown, further, a one-way valve is provided in the injection pipe 422.

[0038] Another object of the present invention is to provide a water purification method, including the following steps: S1: Enhance water activity: Place the required algae to be cultured in the culture frame 37. Then, respectively engage the two grooves at the bottom of the culture frame 37 with the mounting frame 31. Place the entire floating board 1 in the water. Turn on the first motor 33 to drive the driving rod 34 to rotate. When the driving rod 34 rotates, it pushes the push plate 36 to slide through the pressing wheel 35. When the push plate 36 slides, it intermittently pushes the culture frame 37 on the mounting frame 31, so as to impact the left and right sides of the culture frame 37 with water, thereby cleaning the two sides of the culture frame 37, preventing dirt from clogging the outside of the frame during algae cultivation, and increasing the activity of the water during the impact with water to improve the water quality, so that the algae can be cultured in water with sufficient oxygen content during cultivation; S2: Inject oxygen into the water: While the driving rod 34 rotates to enhance the water activity, through the setting of the oxygen generation unit, the injection pipe 422 can continuously supply oxygen to the water, and cooperate with the displacement plate 421 to slide 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, so as to supply oxygen radially and axially to the outside of multiple culture frames 37, thereby ensuring uniform oxygen content in the water outside the culture frame 37.

[0039] There are multiple culture frames 37, which are separately placed on the corresponding mounting frames 31. They can cultivate different types of algae and can independently pick up and place any culture frame 37. Compared with the existing devices, the present invention can store and cultivate multiple types of algae independently during the cultivation of algae, and can quickly pick up and place the culture frame 37 without uniformly disassembling and assembling multiple culture frames 37. Through the setting of the pushing component, when the culture frame 37 cultivates algae in water, the culture frame 37 can be continuously moved. When moving in water, the water flow impacts the frame body of the culture frame 37. On the one hand, it avoids the formation of dirt on the frame body caused by long-term placement of the culture frame 37 in water, resulting in blockage of the frame body. On the other hand, when impacting with water, it can also enhance the activity of water, enabling the water quality to better hydroponically cultivate the algae in the culture frame 37. Through the setting of the oxygen generation unit, oxygen can be continuously injected into the water, enabling the water with sufficient oxygen content to cultivate the algae of high quality. The solar panel 2 supplies the driving energy required for the oxygen generation unit and the pushing component after absorbing light energy; Slide any mounting frame 31 back and forth. At this time, the moving part 302 also slides in the moving groove 301, so as to facilitate the picking up and placing of the culture frame 37 on the mounting frame 31. Through the setting of the spring, when the pushing plate 36 cancels the pushing of the pushing plate 36, the culture frame 37 can be pushed against the sliding rod through the setting of the spring, so as to cooperate with the pushing plate 36 to slide the culture frame 37 back and forth, so as to generate impact in water; When the culture frame 37 slides left and right on the mounting frame 31, both the left and right sides of the culture frame 37 can be cleaned during the impact with water. At this time, the water flow on both the left and right sides of the culture frame 37 impacts the blades 384 during the impact. At this time, the blades 384 rotate after being impacted. When the blades 384 rotate, the central rod 383 rotates. When the central rod 383 rotates, the push-pull plate 385 is synchronously driven to rotate, so that the upper and lower brush plates 382 continuously approach and move away from each other, so as to brush and clean the front and back sides of the culture frame 37 up and down. And in cooperation with the left and right sliding of the culture frame 37, it can also brush the front and back sides of the culture frame 37 evenly left and right, thus avoiding the situation that the water flow cannot directly impact the front and back sides of the culture frame 37, resulting in the blockage of dirt on the front and back sides of the culture frame 37; The electric slider is turned on to drive the rotating frame 40 to rotate circumferentially along the outside of the culture frame 37, so that the oxygen generation unit can evenly supply oxygen to the outside of the oxygen supply frame 37 in a surrounding manner. By supplying oxygen to the water in a surrounding manner, the water quality outside the oxygen supply frame 37 can be supplemented with oxygen to the greatest extent. When the second motor 427 is turned on to drive the cam 428 to rotate, the cam 428 intermittently presses the control plate 425 during rotation, so that the control plate 425 can slide up and down. When the control plate 425 slides up and down, the displacement plate 421 in the vertical frame 42 can be moved up and down through the extension rod 424. When the displacement plate 421 moves up and down, the injection pipe 422 can slide up and down to inject oxygen into the outside of the culture frame 37. Cooperating with the rotation of the rotating frame 40, sufficient oxygen can be supplied to the outside of multiple culture frames 37; When the electric slider is turned on, it drives the rectangular block 11 to slide in the rectangular groove, so that the electric push rod 13 and the air storage tank 436 move on the floating plate 1, which is convenient for taking and placing the lower culture frame 37 through the through hole in the middle of the floating plate 1 without removing the whole device from the water. The setting of the belt pulley and the belt enables the driving rod 34 to rotate and can also drive the rotating part 431 to rotate. When the rotating part 431 rotates, the piston rod 433 continuously compresses the air cylinder 432, so that the air cylinder 432 replenishes oxygen into the air storage tank 436.

[0040] The above shows and describes 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 by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
