Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and in particular to a floating water purification device and its control method. Background Technology

[0002] With the continuous discharge of pollutants into natural water bodies from industrial and agricultural production, urban life, and non-point source pollution, rivers, lakes, reservoirs, and landscape water bodies are generally facing problems such as water quality deterioration and ecological function degradation. Water pollution control has become a key aspect of aquatic ecological environment protection. Excessive pollutants entering water bodies can easily lead to eutrophication, excessive suspended solids, decreased dissolved oxygen, and algal blooms, disrupting the balance of aquatic ecosystems, affecting the landscape function of water bodies and drinking water safety. Therefore, there is an urgent need for efficient, stable, and highly adaptable water purification equipment.

[0003] In the process of realizing this invention, the inventors discovered that existing water purification equipment mostly adopts a fixed purification structure, requiring the purification components to be submerged underwater for continuous operation, which has obvious technical limitations in practical applications. The purification materials are constantly in a state of soaking, adsorption, and rinsing, making them prone to clogging, adsorption saturation, and structural damage. This leads to a rapid decline in purification efficiency, a significant shortening of service life, frequent replacement of consumables, high maintenance costs, and cumbersome operation.

[0004] In addition, traditional equipment lacks an active control mechanism for the timing of purification and the duration of immersion. The purification materials operate under continuous high load, which makes it impossible to reduce losses while ensuring the purification effect. It is difficult to adapt to diverse treatment scenarios with different water areas and different levels of pollution, and it has shortcomings in long-term effectiveness, economy and adaptability. Summary of the Invention

[0005] This invention provides a floating water purification device and its control method to address the shortcomings of existing water purification devices, such as high energy consumption.

[0006] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0007] According to one aspect of the present invention, a floating water purification device is provided, which mainly includes: a floating body, a driving component, a water inlet component, and a purification component. The floating body is suspended on the water and can move on the water surface. The driving component is disposed on the floating body. The water inlet component includes a water inlet pipe, which is connected to the output end of the driving component. The purification component is connected to the floating body and communicates with the water inlet pipe. The purification component is provided with a water suction part. The purification component is isolated from the water body. The driving component causes the water inlet of the water inlet pipe to alternately be in a water inlet state and a water outlet state. In the water inlet state, the water suction part guides the water body from the water inlet into the purification component and discharges it from the water outlet of the purification component after purification.

[0008] In this type of embodiment, by setting a driving component, the water inlet of the water inlet pipe can be controlled to alternately be in the water inlet state and the water outlet state. By setting the purification component to be connected to the water inlet pipe, and setting a water suction part inside the purification component, water can be guided into the purification component when the water inlet pipe is in the water inlet state. By setting the purification component to be isolated from the water body, the direct connection between the external water body and the inside of the purification component can be blocked. When the water inlet pipe is in the water outlet state, water is prevented from entering the purification component. Thus, the water inlet of the purification component can be controlled intermittently, that is, the purification component does not need to be constantly immersed in water, which can reduce the immersion loss and scouring wear of the purification component, thereby improving the service life of the purification component.

[0009] On the other hand, since the inlet alternates between water intake and water outlet states, the water depth at the inlet will vary within a certain range, allowing water of different depths to enter the purification component and achieving the effect of stratified purification of water of different depths.

[0010] In some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes a first rotating shaft that is drivenly connected to the output end, and the water inlet component further includes a rotating component, a guide rail mechanism, a sliding component, and a limiting rail. The rotating component is connected to the first rotating shaft; the guide rail mechanism is connected to the floating body and has a sliding track extending along the height direction of the floating body; the sliding component is slidably connected to the rotating component and the sliding track respectively; the limiting rail is located on the floating body and has an arc-shaped track protruding away from the purification component, and the water inlet pipe passes through the arc-shaped track and is slidably connected to the sliding component.

[0011] In this type of embodiment, by setting a sliding connection between the sliding member and the rotating member, the rotating member being connected to a first rotating shaft, and the first rotating shaft being connected to the output end of the drive component, the rotational power output by the drive component can be converted into a reciprocating driving force for the sliding member, causing the sliding member to reciprocate. By setting a sliding fit between the sliding member and the sliding track, which extends along the height direction of the floating body, the movement direction of the sliding member can be constrained, causing the sliding member to reciprocate along the height direction of the floating body. By setting a sliding fit between the water inlet pipe and the sliding member, the water inlet pipe can reciprocate synchronously with the sliding member along the height direction of the floating body, thereby enabling the water inlet of the water inlet pipe to alternately be in a water inlet state and a water outlet state.

[0012] On the other hand, by setting the inlet pipe to pass through the arc-shaped track, with the track protruding away from the purification components, the inlet pipe slides into the arc-shaped track. The track guides and constrains the inlet pipe's trajectory, causing it to reciprocate along the height of the floating body while simultaneously displacing horizontally away from the purification components. The arc shape of the track, protruding away from the purification components, prevents collisions between the inlet pipe and the floating body, purification components, and connecting pipes during movement, ensuring smooth reciprocating motion and eliminating the risk of structural jamming. Simultaneously, it expands the horizontal coverage of the inlet, increasing the lateral water purification coverage area of ​​the floating water purification equipment.

[0013] In some exemplary embodiments of the present invention, based on the foregoing scheme, the water inlet pipe is connected to the purification component through a flexible component.

[0014] In this type of embodiment, by setting the water inlet pipe to be connected to the purification component through a flexible component, a deformable sealed water flow channel can be formed between the water inlet pipe and the purification component, while compensating for the displacement difference generated during the movement of the water inlet pipe.

[0015] On the other hand, by setting flexible components, the vibration and impact transmitted from the drive component to the water inlet pipe can be absorbed, thereby preventing the vibration from being directly transmitted to the inside of the purification component and protecting the internal stability of the purification component.

[0016] In some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes a second rotating shaft that is drivenly connected to the output end, and the purification component further includes a purification shell and at least one purification block. The purification shell is connected to the floating body and has a receiving cavity for accommodating the water absorption part. The water absorption part is connected to the second rotating shaft. The purification block is disposed on the side of the receiving cavity near the water outlet, and the other side of the receiving cavity is connected to the water inlet pipe.

[0017] In this type of embodiment, by setting the second rotating shaft to be connected to the output end of the drive component and the water suction part to be connected to the second rotating shaft, the rotational power output by the drive component can be transmitted to the water suction part, so that the water suction part generates the power to suck water.

[0018] On the other hand, by setting the purification block on the side of the receiving cavity near the water outlet, the water flowing in from the inlet of the inlet pipe can first diffuse and buffer in the receiving cavity before flowing to the purification block, thereby avoiding the water flow directly impacting the purification block and making the water flow speed through the purification block more uniform.

[0019] In some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes a linkage component. The linkage component mainly includes a linkage motor, a push rod, a third rotating shaft, and a limiting rod. The linkage motor is located on the floating body; the push rod is connected to the linkage motor; the third rotating shaft is threadedly connected to the push rod through a connecting ring; the limiting rod is located on the floating body, and the connecting ring is sleeved on the limiting rod. Under the guidance of the limiting rod, the third rotating shaft moves away from or closer to the rotating component and the drive component, so that the third rotating shaft is driven between the first rotating shaft and the drive component or prevents the first rotating shaft and the drive component from being driven together.

[0020] In this type of embodiment, by setting the push rod to be connected to the linkage motor and the third rotating shaft to be threadedly connected to the push rod via a connecting ring, the rotational power output by the linkage motor can be converted into linear motion of the connecting ring, driving the third rotating shaft to move along the push rod. This allows the third rotating shaft to be connected between the first rotating shaft and the drive assembly, or to prevent the first rotating shaft and the drive assembly from being connected. In other words, the connection and disconnection of power transmission between the first rotating shaft and the drive assembly can be controlled. When connected, the inlet of the water inlet pipe alternately goes through the water inlet and water outlet states; when disconnected, the inlet of the water inlet pipe remains in either the water inlet or water outlet state, so that the floating water purification equipment has different working modes.

[0021] On the other hand, by setting the connecting ring to be fitted onto the limiting rod, the connecting ring can be restricted to rotate synchronously with the push rod, ensuring that the connecting ring can only move along the axial direction of the push rod, avoiding rotational deviation of the third rotating shaft, ensuring the matching accuracy of the third rotating shaft with the rotating parts and drive components, and thus improving the stability and reliability of the power transmission process.

[0022] In some exemplary embodiments of the present invention, based on the aforementioned scheme, the drive assembly mainly includes a drive motor and a fourth rotating shaft, the fourth rotating shaft being connected to the drive motor in a transmission manner; wherein, the fourth rotating shaft is provided with a first gear, the second rotating shaft is provided with a second gear meshing with the first gear, one end of the third rotating shaft is provided with a third gear meshing with the second gear, and the other end of the third rotating shaft is provided with a fifth gear meshing with the fourth gear of the first rotating shaft.

[0023] In this type of embodiment, by setting the drive motor to be connected to the fourth rotating shaft, the fourth rotating shaft having a first gear, the second rotating shaft having a second gear meshing with the first gear, one end of the third rotating shaft having a third gear meshing with the second gear, and the other end of the third rotating shaft having a fifth gear meshing with the fourth gear of the first rotating shaft, the rotational power output by the drive motor can be transmitted sequentially to the second rotating shaft and the first rotating shaft through gear meshing, thereby realizing the function of driving multiple actuators simultaneously from the same power source, that is, power is transmitted simultaneously to the second rotating shaft and the first rotating shaft, so that the water suction part and the water inlet pipe work synchronously.

[0024] This design reduces the number of power sources, simplifies equipment structure and control circuits, and lowers manufacturing costs and assembly difficulty. It also ensures a fixed transmission ratio between the suction speed of the suction unit and the movement frequency of the inlet pipe. This allows for precise matching between the suction action of the suction unit and the inlet action of the inlet pipe, preventing energy waste caused by the suction unit idling when the inlet pipe is in the outlet state, and avoiding reduced inlet efficiency due to insufficient suction when the inlet pipe is in the inlet state. Ultimately, this improves the overall purification efficiency of the equipment. Furthermore, it reduces potential points of failure in the power system, avoids problems such as water flow impact and abnormal pipeline pressure caused by asynchronous components, and extends the service life of the equipment.

[0025] In some exemplary embodiments of the present invention, based on the foregoing scheme, two water inlet components symmetrically arranged on both sides of the floating body and two purification components symmetrically arranged on both sides of the floating body are provided.

[0026] In this type of embodiment, by setting two water inlet components symmetrically arranged on both sides of the floating body and two purification components symmetrically arranged on both sides of the floating body, the water to be purified can be drawn from both sides of the floating body at the same time and the purification treatment can be completed simultaneously. This can cover the water areas on both sides of the floating body at the same time, thereby improving the water treatment efficiency.

[0027] On the other hand, by symmetrically arranging the water inlet components and purification components on both sides, the forces on both sides of the floating body can be kept evenly balanced, avoiding tilting or overturning due to concentrated load on one side, thereby improving the stability and wave resistance of the floating water purification equipment on the water surface.

[0028] In some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes a spraying assembly, which mainly includes a receiving tank, a nozzle mechanism, and a pumping mechanism. The receiving tank is filled with a purification liquid for purification; the nozzle mechanism has multiple nozzles; and the pumping mechanism is connected to the receiving tank and the nozzle mechanism.

[0029] In this type of embodiment, a pumping mechanism is provided to connect the receiving tank and the nozzle mechanism. The receiving tank stores the purification liquid and can deliver the purification liquid to the nozzle mechanism. The multiple nozzles of the nozzle mechanism can then be used to spray the purification liquid to the area to be purified, thereby expanding the purification range.

[0030] In some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes at least one auxiliary purification component. The auxiliary purification component mainly includes a locking block, an extension rod, and a receiving frame. The floating body is provided with a fixing groove that matches the shape of the locking block; the extension rod is connected to the locking block, and the floating body is provided with a sliding groove that matches the shape of the extension rod to allow the auxiliary purification component to slide to the fixing groove; the receiving frame is connected to the extension rod, and the receiving frame is provided with a purification agent.

[0031] In this type of embodiment, by setting the extension rod to be connected to the card block and the receiving frame to be connected to the extension rod, the floating body is provided with a fixing groove that matches the shape of the card block and a sliding groove that matches the shape of the extension rod. The auxiliary purification component can be slid along the sliding groove to the fixing groove and fixed by the card block, thereby realizing the quick installation and removal function of the auxiliary purification component. The auxiliary purification component can be quickly installed according to the purification needs, or it can be quickly disassembled for maintenance and replacement.

[0032] According to another aspect of the present invention, a control method suitable for the floating water purification device described above is provided, the control method comprising: Control the floating object to move it to the area to be cleaned; Start the drive component to make the water inlet pipe alternate between water inlet and water outlet states; Activate the water intake unit. With the water inlet pipe in the water intake state, the water from the area to be purified enters the purification unit and is discharged from the outlet of the purification unit after purification.

[0033] In this type of embodiment, by alternating between water inlet and water outlet states, the purification component does not need to be constantly immersed in water, thereby reducing the adhesion and corrosion of the purification component by impurities and microorganisms in the water and extending the service life of the purification component.

[0034] On the other hand, since the inlet alternates between water intake and water outlet states, the water depth at the inlet will vary within a certain range, allowing water of different depths to enter the purification component and achieving the effect of stratified purification of water of different depths.

Detailed Implementation

[0048] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the invention, are intended to cover non-exclusive inclusion.

[0050] In the description of the embodiments of the present invention, the technical terms "first," "second," "third," "fourth," "fifth," etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present invention, "multiple" means two or more, unless otherwise explicitly defined.

[0051] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0052] In the description of the embodiments of this invention, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0053] In the description of the embodiments of the present invention, the technical terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, operated or used in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0054] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0055] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the technical term "contact" should be interpreted broadly, and can be direct contact, contact through an intermediate medium layer, contact between two contacting parties with substantially no interaction force, or contact between two contacting parties with interaction force.

[0056] In the process of developing this invention, it was discovered that isolating the purification component from the water body, thus preventing it from being constantly submerged, can reduce wear and tear on the purification component. However, if the purification component is isolated from the water body, it needs to be placed inside a floating body or above the water surface.

[0057] If the purification components are placed inside the floating body, the outer shell of the floating body needs to be disassembled when the purification components are repaired or the purification blocks are replaced. The maintenance operation is cumbersome and time-consuming. In addition, water can easily accumulate inside the floating body due to sealing failure or condensation, which will not only corrode the purification components, but also change the overall weight distribution of the equipment and affect the floating stability.

[0058] If the purification component is placed above the water surface, other devices are needed to guide the water to the purification component to achieve the purification function. However, during the purification process, the purification component still needs to be in continuous contact with the water. If the water pollution level is low and the purification component does not need to be in continuous contact with the water to complete the purification, the device needs to be turned off frequently to effectively reduce the wear and tear on the purification component. However, this method consumes a lot of energy.

[0059] Therefore, this invention proposes a floating water purification device.

[0060] like Figures 1 to 4 As shown, according to one aspect of the present invention, a floating water purification device is provided. The floating water purification device can be used to treat organic pollution, ammonia nitrogen pollution, nitrogen and phosphorus pollution, etc., in water bodies. The floating water purification device mainly includes: a floating body 1, a drive assembly 2, a water inlet assembly 3, and a purification assembly 4. The floating body 1, as the basic support platform of the floating water purification device, can be suspended on the water and can move on the water surface, thereby expanding the purification range of the floating water purification device. The floating body 1 can move on the water surface by setting up propulsion mechanisms such as water jet propulsion or propellers. The floating body 1 can be suspended on the water by setting up structures such as floats or floating platforms. In addition, the floating body 1 can also integrate a navigation and positioning module and a path planning algorithm to achieve autonomous navigation or operation according to a predetermined trajectory, making it particularly suitable for the purification of large-area water bodies (such as reservoirs and lakes).

[0061] Furthermore, the drive assembly 2 is located on the floating body 1, meaning that the drive assembly 2 can be fixed to the floating body 1. The drive assembly 2 may include driving devices such as stepper motors, servo motors, and geared motors. The drive assembly 2 may also be equipped with transmission components such as reducers and couplings to achieve smooth power transmission, reduce power loss, and reduce the impact of motor vibration on the overall structure of the equipment. The water inlet assembly 3 may include a water inlet pipe 31. The water inlet pipe 31 can be connected to the output end of the drive assembly 2. The water inlet pipe 31 may be made of a corrosion-resistant, aging-resistant, and scale-resistant material, for example, the same material as stainless steel pipes, rigid PVC pipes, or flexible corrugated pipes.

[0062] The purification component 4 can be connected to the floating body 1, meaning the purification component 4 can be fixed to the floating body 1. The purification component 4 can be used to purify water. The purification component 4 can be connected to the inlet pipe 31. The purification component 4 may contain a water suction section 41. The water suction section 41 provides power for the flow of water within the inlet pipe 31 and the purification component 4. The water suction section 41 can be a centrifugal pump, axial flow pump, self-priming pump, or other fluid transfer pump equipment.

[0063] The drive assembly 2 can alternately switch the inlet 311 of the water inlet pipe 31 between an inlet state and an outlet state. In the inlet state, the suction unit 41 guides water from the inlet 311 into the purification assembly 4, and after purification by the purification assembly 4, it is discharged from the outlet 411. The purification assembly 4 can be isolated from the water. This means that the purification assembly 4 is not permanently submerged in water, but rather receives water to be purified periodically through the controlled inlet assembly 3, thereby reducing losses.

[0064] According to an embodiment of the present invention, by setting the driving component 2, the inlet 311 of the water inlet pipe 31 can be controlled to alternately be in the water inlet state and the water outlet state. By setting the purification component 4 to be connected to the water inlet pipe 31, and setting the water absorption part 41 inside the purification component 4, water can be guided into the purification component 4 when the water inlet pipe 31 is in the water inlet state. By setting the purification component 4 to be isolated from the water, the direct communication between the external water and the interior of the purification component 4 can be blocked. When the water inlet pipe 31 is in the water outlet state, water is prevented from entering the purification component 4. Thus, the water inlet of the purification component 4 can be controlled intermittently, that is, the purification component 4 does not need to be constantly immersed in water, which can reduce the soaking loss and scouring wear of the purification component 4, thereby improving the service life of the purification component 4. In the water outlet state, a "rest period" can be formed inside the purification component 4, which is conducive to the shedding of trapped pollutants in a low humidity environment. It is also conducive to the water entering the purification component 4 fully contacting the purification substance, avoiding the water flow speed being too fast due to continuous water inlet, and the insufficient purification caused by the "later water inlet" squeezing the "first water inlet".

[0065] On the other hand, since the inlet 311 alternates between the water inlet state and the water outlet state, the water inlet depth of the inlet 311 will vary within a certain range, so that water of different depths can enter the purification component 4, thereby achieving the effect of stratified purification of water of different depths by the purification component 4.

[0066] like Figures 1 to 5As shown, in some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device may further include a first rotating shaft 5 that is drivenly connected to the output end. The water inlet assembly 3 may further include a rotating member 32, a guide rail mechanism 33, a sliding member 34, and a limiting rail 35. The rotating member 32 may be connected to the first rotating shaft 5. The first rotating shaft 5 may drive the rotating member 32 to rotate. The rotating member 32 may include a turntable 322 and a connecting portion 321. The turntable 322 is generally circular. The central axis of the turntable 322 may coincide with the central axis of the first rotating shaft 5. The connecting portion 321 may be configured as a protrusion on the turntable 322 facing the sliding member 34. The sliding member 34 may have a first sliding groove 341 and a second sliding groove 342. The rotating member 32 and the sliding member 34 can be slidably connected through the cooperation of the connecting part 321 and the first sliding groove 341. The sliding member 34 is slidably connected to the rotating member 32 and the sliding track 331 respectively, so that the rotating member 32 can convert the rotational motion of the first rotating shaft 5 into the reciprocating motion of the sliding member 34 along the sliding track 331. The guide rail mechanism 33 can be connected to the floating body 1. The guide rail mechanism 33 can include two guide rail parts 332. The guide rail mechanism 33 is provided with a sliding track 331 extending along the height direction of the floating body 1 (e.g., perpendicular to the water surface). Specifically, the two guide rail parts 332 can be respectively provided at both ends of the sliding member 34, and each guide rail part 332 can be provided with a sliding track 331. The two ends of the sliding member 34 can be slidably connected to the two sliding tracks 331. In other words, the sliding member 34 is clamped and limited between the two sliding tracks 331 and can slide up and down along the sliding track 331. This arrangement can prevent the sliding member 34 from tilting during sliding.

[0067] Furthermore, the limiting rail 35 can be provided on the floating body 1. The limiting rail 35 is provided in a direction away from the purification component 4 (e.g., Figure 1 The right side of the limiting rail 35 (shown) features a protruding arc-shaped track 351. At least a portion of the arc-shaped track 351 extends underwater. The water inlet pipe 31 passes through the arc-shaped track 351 and is slidably connected to the sliding member 34. The range of water inlet depth can be flexibly designed and adjusted by changing the length of the sliding track 331 or the radius of curvature of the arc-shaped track 351 to adapt to different application scenarios. Figures 4 to 6 As shown, the water inlet pipe 31 may be provided with an extension 312. A sliding block 37, slidably connected to the second sliding groove 342 of the sliding member 34, may be provided within the second sliding groove 342. The extension 312 may be connected to the sliding block 37 to allow the water inlet pipe 31 to slide relative to the sliding member 34. For example, the extension 312 may be inserted into the sliding block 37.

[0068] According to an embodiment of the present invention, by setting the sliding member 34 and the rotating member 32 to be slidably connected, the rotating member 32 to be connected to the first rotating shaft 5, and the first rotating shaft 5 to be connected to the output end of the drive assembly 2, the rotational power output by the drive assembly 2 can be converted into the reciprocating motion driving force of the sliding member 34, causing the sliding member 34 to reciprocate. By setting the sliding member 34 to be slidably engaged with the sliding track 331, which extends along the height direction of the floating body 1, the movement direction of the sliding member 34 can be constrained, causing the sliding member 34 to reciprocate along the height direction of the floating body 1. By setting the water inlet pipe 31 to be slidably engaged with the sliding member 34, the water inlet pipe 31 can reciprocate synchronously with the sliding member 34 along the height direction of the floating body 1, thereby enabling the water inlet 311 of the water inlet pipe 31 to alternately be in the water inlet state and the water outlet state.

[0069] On the other hand, by setting the inlet pipe 31 to pass through the arc-shaped track 351, with the arc-shaped track 351 protruding away from the purification component 4, the inlet pipe 31 and the arc-shaped track 351 slide in cooperation. The arc-shaped track 351 guides and constrains the movement trajectory of the inlet pipe 31, causing the inlet pipe 31 to reciprocate along the height direction of the floating body 1 while simultaneously displacing horizontally away from the purification component 4. The arc shape of the arc-shaped track 351, protruding away from the purification component 4, can prevent the inlet pipe 31 from colliding with the floating body 1, the purification component 4, and connecting pipes during movement, ensuring the smoothness of the reciprocating movement of the inlet pipe 31 and eliminating the risk of structural jamming. At the same time, it can expand the horizontal coverage range of the inlet 311, increasing the lateral water purification coverage area of ​​the floating water purification equipment.

[0070] like Figures 1 to 6 As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the water inlet pipe 31 is connected to the purification component 4 via the flexible member 36.

[0071] According to an embodiment of the present invention, by setting the water inlet pipe 31 to be connected to the purification component 4 through the flexible member 36, a deformable sealed water flow channel can be formed between the water inlet pipe 31 and the purification component 4, and the displacement difference generated during the movement of the water inlet pipe 31 can be compensated.

[0072] On the other hand, by setting the flexible component 36, the vibration and impact transmitted from the drive component 2 to the water inlet pipe 31 can be absorbed, thereby preventing the vibration from being directly transmitted to the interior of the purification component 4 and protecting the stability of the interior of the purification component 4.

[0073] Furthermore, by setting the arc-shaped track 351 to protrude away from the purification component 4, the flexible part 36 between the water inlet pipe 31 and the purification component 4 can always be in a natural bending state of outward stretching, thereby avoiding dead bends or excessive compression caused by inward bending of the hose, and reducing the water flow resistance and material fatigue wear of the pipeline.

[0074] like Figures 1 to 7 As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the floating water purification device further includes a second rotating shaft 6 that is drivenly connected to the output end. The purification assembly 4 also includes a purification housing 42 and at least one purification block 43. The purification housing 42 is connected to the floating body 1, that is, the purification housing 42 can be fixed to the floating body 1. The purification housing 42 has a receiving cavity 421 for accommodating the water absorption part 41. The water absorption part 41 is connected to the second rotating shaft 6, that is, the water absorption part 41 can be fixed to the second rotating shaft 6. The purification block 43 is disposed on one side of the receiving cavity 421 near the water outlet 411, and the other side of the receiving cavity 421 is connected to the water inlet pipe 31. The water absorption part 41 can be an impeller structure directly connected to the second rotating shaft 6. When the second rotating shaft 6 is driven, the impeller rotates and generates centrifugal force, forming a negative pressure at the water inlet 311, thereby actively drawing water. The water absorption part 41 can also be replaced by a bevel gear.

[0075] Furthermore, the first portion 422 of the purification housing 42 near the purification block 43 can be detachably connected to the remaining second portion 423 of the purification housing 42 to facilitate the replacement of the purification block 43. For example, the first portion 422 of the purification housing 42 can be threadedly connected to the second portion 423 of the purification housing 42.

[0076] Furthermore, such as Figure 7 As shown, the purification housing 42 can be equipped with three purification blocks 43 arranged sequentially from left to right. The purification blocks 43 are engaged with the purification housing 42. Specifically, four mesh bodies can be fixed in the receiving cavity 421, separating three sections, and one purification block 43 is placed in each of the three sections. The type of purification block 43 can be selected according to the type of pollution; for example, the three purification blocks 43 can be ceramic rings, activated carbon, and quartz sand, respectively.

[0077] According to an embodiment of the present invention, by setting the second rotating shaft 6 to be connected to the output end of the drive assembly 2, and the water suction part 41 to be connected to the second rotating shaft 6, the rotational power output by the drive assembly 2 can be transmitted to the water suction part 41, so that the water suction part 41 generates the power to suck water.

[0078] On the other hand, by setting the purification block 43 on the side of the receiving cavity 421 near the outlet 411, the water flowing in from the inlet 311 of the inlet pipe 31 can first diffuse and buffer in the receiving cavity 421 before flowing to the purification block 43, thereby avoiding the water flow directly impacting the purification block 43 and making the water flow speed through the purification block 43 more uniform.

[0079] like Figures 1 to 3 and Figure 8As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the floating water purification device further includes a linkage component 7. The linkage component 7 mainly includes a linkage motor 71, a push rod 72, a third rotating shaft 73, and a limiting rod 75. The linkage motor 71 is located on the floating body 1, meaning the linkage motor 71 can be fixed to the floating body 1. The push rod 72 is connected to the linkage motor 71. The third rotating shaft 73 is threadedly connected to the push rod 72 via a connecting ring 74. The push rod 72 can be a threaded rod. The limiting rod 75 is located on the floating body 1, meaning the limiting rod 75 can be fixed to the floating body 1. The connecting ring 74 is sleeved on the limiting rod 75. Guided by the limiting rod 75, the third rotating shaft 73 moves away from or near the rotating component 32 and the drive component 2, causing the third rotating shaft 73 to be driveably connected between the first rotating shaft 5 and the drive component 2 or preventing the first rotating shaft 5 and the drive component 2 from being driveably connected.

[0080] According to an embodiment of the present invention, by setting the push rod 72 to be connected to the linkage motor 71 and the third rotating shaft 73 to be threadedly connected to the push rod 72 through the connecting ring 74, the rotational power output by the linkage motor 71 can be converted into the linear motion of the connecting ring 74, driving the third rotating shaft 73 to move along the push rod 72, so that the third rotating shaft 73 is connected to the first rotating shaft 5 and the drive assembly 2, or the first rotating shaft 5 and the drive assembly 2 are prevented from being connected. That is, the connection and disconnection of the power transmission between the first rotating shaft 5 and the drive assembly 2 can be controlled. When connected, the inlet 311 of the water inlet pipe 31 alternately goes through the water inlet state and the water outlet state; when disconnected, the inlet 311 of the water inlet pipe 31 remains in the water inlet state or the water outlet state, so that the floating water purification equipment has different working modes.

[0081] In other words, the linkage component 7 enables the purification component 4 to have three operating modes: intermittent purification mode, continuous purification mode, and standby mode. The operating mode can be adjusted in real time according to the detected pollution level of the water.

[0082] In the intermittent purification mode, the third rotating shaft 73 is connected between the first rotating shaft 5 and the drive component 2, and the water inlet pipe 31 reciprocates to achieve intermittent water intake and stratified purification, which is suitable for routine maintenance and most pollution scenarios.

[0083] In continuous purification mode, when the inlet 311 of the inlet pipe 31 moves underwater, the third rotating shaft 73 is controlled to move away from the first rotating shaft 5 and the drive component 2. At this time, the purification component 4 continuously receives water, which is suitable for scenarios where the area to be purified is heavily polluted. The degree of pollution in the area to be purified can be detected by a water quality sensor.

[0084] In standby mode, when the water inlet 311 of the water inlet pipe 31 moves to the water surface, the third rotating shaft 73 is controlled to move away from the first rotating shaft 5 and the drive component 2, and the purification component 4 does not take in water at this time.

[0085] On the other hand, by setting the connecting ring 74 to be sleeved on the limiting rod 75, the connecting ring 74 can be restricted to rotate synchronously with the push rod 72, ensuring that the connecting ring 74 can only move along the axial direction of the push rod 72, avoiding rotational deviation of the third rotating shaft 73, ensuring the matching accuracy of the third rotating shaft 73 with the rotating part 32 and the drive assembly 2, thereby improving the stability and reliability in the power transmission process.

[0086] like Figures 1 to 3 and Figure 8 As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the drive assembly 2 mainly includes a drive motor 21 and a fourth rotating shaft 22. The fourth rotating shaft 22 is connected to the drive motor 21 in a transmission manner. The fourth rotating shaft 22 is provided with a first gear 23, the second rotating shaft 6 is provided with a second gear 24 meshing with the first gear 23, one end of the third rotating shaft 73 is provided with a third gear 25 meshing with the second gear 24, and the other end of the third rotating shaft 73 is provided with a fifth gear 27 meshing with the fourth gear 26 of the first rotating shaft 5.

[0087] According to an embodiment of the present invention, by configuring a drive motor 21 to be connected to a fourth rotating shaft 22, the fourth rotating shaft 22 to have a first gear 23, the second rotating shaft 6 to have a second gear 24 meshing with the first gear 23, one end of the third rotating shaft 73 to have a third gear 25 meshing with the second gear 24, and the other end of the third rotating shaft 73 to have a fifth gear 27 meshing with the fourth gear 26 of the first rotating shaft 5, the rotational power output by the drive motor 21 can be transmitted sequentially to the second rotating shaft 6 and the first rotating shaft 5 through gear meshing. This enables the function of simultaneously driving multiple actuators from the same power source, i.e., power is simultaneously transmitted to the second rotating shaft 6 and the first rotating shaft 5, allowing the water suction part 41 and the water inlet pipe 31 to work synchronously. By designing the gear ratio of each gear, the optimal suction speed of the water suction part 41 and the optimal reciprocating frequency of the water inlet pipe 31 can be precisely matched. For example, it can be set so that the water inlet pipe 31 rotates a specific number of times each time it completes the cycle of "downward insertion - water intake - upward lifting - emptying", ensuring that a sufficient amount of water is drawn in during the limited water intake period, while avoiding doing too much useless work during non-water intake periods.

[0088] This design reduces the number of power sources, simplifies the equipment structure and control circuit, and lowers manufacturing costs and assembly difficulty. It also ensures a fixed transmission ratio between the suction speed of the suction unit 41 and the movement frequency of the inlet pipe 31. This allows for precise matching between the suction action of the suction unit 41 and the inlet action of the inlet pipe 31, preventing energy waste caused by the suction unit 41 idling when the inlet pipe 31 is in the water-discharging state, and avoiding reduced water intake efficiency due to insufficient suction of the suction unit 41 when the inlet pipe 31 is in the water-inlet state. Ultimately, this improves the overall purification efficiency of the equipment. Furthermore, it reduces potential points of failure in the power system, avoids problems such as water flow impact and abnormal pipeline pressure caused by asynchronous components, and extends the service life of the equipment.

[0089] On the one hand, from the perspective of structure and cost, by using a single drive motor 21 as the total power source, the number of independent power units can be reduced, thereby simplifying the overall structural layout of the equipment, reducing the complexity of electrical wiring and control circuits, and ultimately reducing the manufacturing cost and assembly difficulty of the equipment.

[0090] On the other hand, from the perspective of operational efficiency, the rigid transmission method of gear meshing can ensure that the suction speed of the water suction unit 41 and the movement frequency of the water inlet pipe 31 maintain a fixed transmission ratio. This allows the suction action of the water suction unit 41 to be precisely matched with the water inlet action of the water inlet pipe 31, avoiding energy waste caused by the water suction unit 41 idling when the water inlet pipe 31 is in the water outlet state. At the same time, it avoids the reduced water inlet efficiency caused by insufficient suction of the water suction unit 41 when the water inlet pipe 31 is in the water inlet state, ultimately improving the overall purification efficiency of the equipment.

[0091] Furthermore, from an operational reliability perspective, a single power source design can reduce the number of potential failure points and lower the overall failure rate of the power system. Simultaneously, synchronous operation can avoid problems such as water flow impact and abnormal pipeline pressure caused by asynchronous operation of two actuators, thereby extending the service life of the equipment's core components.

[0092] Furthermore, the fourth rotating shaft 22 can be connected to the drive motor 21 via the drive shaft 28. Specifically, the output shaft of the drive motor 21 can be connected to the drive shaft 28 via a coupling. The side of the drive shaft 28 furthest from the drive motor 21 (e.g., Figure 3 A pulley 292 may be provided on the left side of the drive shaft 28 shown. The side of the fourth shaft 22 furthest from the first gear 23 (e.g., Figure 3 A pulley 292 may also be provided on the right side of the fourth rotating shaft 22 shown. The two pulleys 292 can be connected by a transmission belt 291. Driven by the drive motor 21, the drive shaft 28 drives the fourth rotating shaft 22 to rotate, thereby driving the first gear 23 to rotate. The first gear 23, the second gear 24, the third gear 25, the fourth gear 26, and the fifth gear 27 can be bevel gears.

[0093] Furthermore, to simplify the structure of the floating water purification equipment, a propulsion blade 29 can be installed on the drive shaft 28, thereby using the drive motor 21 to drive the propulsion blade 29 to rotate, so as to realize the movement function of the floating water purification equipment.

[0094] like Figures 1 to 3 As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the floating water purification device may be provided with two water inlet components 3 symmetrically arranged on both sides of the floating body 1, and two purification components 4 symmetrically arranged on both sides of the floating body 1. Figure 1As shown, the first rotating shaft 5 can extend from within the floating body 1, passing through the side wall of the floating body 1 to both sides of the floating body 1, so that the two water inlet components 3 can be located on both sides of the first rotating shaft 5 respectively. Further, as... Figure 1 As shown, the second rotating shaft 6 can extend from inside the floating body 1, pass through the side wall of the floating body 1 and extend to both sides of the floating body 1, so that the two purification components 4 can be located on both sides of the second rotating shaft 6 respectively.

[0095] According to an embodiment of the present invention, by setting two water inlet components 3 symmetrically arranged on both sides of the floating body 1 and two purification components 4 symmetrically arranged on both sides of the floating body 1, water to be purified can be drawn from both sides of the floating body 1 and purified simultaneously, thereby covering the water areas on both sides of the floating body 1 at the same time, which can improve the water treatment efficiency.

[0096] On the other hand, the symmetrical arrangement of the water inlet component 3 and the purification component 4 on both sides can keep the force on both sides of the floating body 1 evenly balanced, avoiding tilting or overturning due to concentrated load on one side, thereby improving the stability and wave resistance of the floating water purification equipment on the water surface.

[0097] According to embodiments of the present invention, the transmission structure of the present invention can be replaced by other transmission methods. The first rotating shaft 5, the second rotating shaft 6, the push rod 72, the third rotating shaft 73, the limiting rod 75, the drive rotating shaft 28, the fourth rotating shaft 22, the first gear 23, the second gear 24, the third gear 25, the fourth gear 26, the fifth gear 27 and other transmission structures can be made of lighter materials to reduce the overall weight, improve the range, and adapt to autonomous inspection.

[0098] like Figures 1 to 3As shown, in some exemplary embodiments of the present invention, based on the foregoing scheme, the floating water purification device further includes a spraying assembly 8. The spraying assembly 8 mainly includes a receiving tank 81, a nozzle mechanism 82, and a pumping mechanism 83. The receiving tank 81 is filled with a purification liquid for purification. The nozzle mechanism 82 has multiple nozzles 821. The nozzles 821 can have different orientations. The pumping mechanism 83 is connected between the receiving tank 81 and the nozzle mechanism 82. Further, two receiving tanks 81 can be provided. The pumping mechanism 83 is located between the two receiving tanks 81. The pumping mechanism 83 can include, but is not limited to, a water pump, diaphragm pump, plunger pump, gear pump, screw pump, peristaltic pump, pneumatic pump, electromagnetic pump, piezoelectric pump, and gravity flow control mechanism, for conveying the purification liquid from the receiving tank 81 to the nozzle mechanism 82. The inlet end of the pumping mechanism 83 can be connected to both receiving tanks 81 respectively, and the top of the receiving tank 81 can be provided with a spray plate 822 for mounting multiple nozzles 821. The outlet of the pumping mechanism 83 can be connected to the spray plate 822. After the purified liquid enters the spray plate 822, it is sprayed out by the nozzle 821. Since the purified liquid reaches the water surface after passing through the air around the water surface after being sprayed out by the nozzle 821, the spraying assembly 8 can also purify the air around the water surface. The type of purified liquid can be determined according to the type of pollution in the water body. For example, in the case of nitrogen and phosphorus pollution, the purified liquid can be an oxidizing agent, a biological agent, or an integrated ammonia and phosphorus removal agent.

[0099] According to an embodiment of the present invention, a pumping mechanism 83 connects a receiving tank 81 and a nozzle mechanism 82. The receiving tank 81 stores the purification liquid and can transport the purification liquid to the nozzle mechanism 82. The multiple nozzles 821 of the nozzle mechanism 82 can spray the purification liquid to the area to be purified, thereby expanding the purification range. Multiple nozzles 821 with different orientations (such as some forward, some to the sides, and some at a certain angle) can form a three-dimensional spray surface, which can treat surface water and also affect a certain depth underwater through the sedimentation of water droplets.

[0100] According to embodiments of the present invention, electronic components such as the pumping mechanism 83, the linkage motor 71, and the drive motor 21 can be waterproof electrical components, or waterproof housings can be added to their components. Furthermore, shaft seals can be added to the first rotating shaft 5 and the second rotating shaft 6 for further waterproofing, thereby extending the service life of the equipment.

[0101] like Figure 1 , Figure 7 and Figure 9As shown, in some exemplary embodiments of the present invention, based on the aforementioned scheme, the floating water purification device further includes at least one auxiliary purification component 9. The auxiliary purification component 9 mainly includes a locking block 91, an extension rod 92, and a receiving frame 93. The floating body 1 is provided with a fixing groove 11 that matches the shape of the locking block 91. The extension rod 92 is connected to the locking block 91, and the floating body 1 is provided with a sliding groove 12 that matches the shape of the extension rod 92, allowing the auxiliary purification component 9 to slide into the fixing groove 11. The receiving frame 93 is connected to the extension rod 92, and the receiving frame 93 contains a purifying agent 94. The purifying agent 94 can be a solid purifying agent 94. The type of purifying agent 94 can be determined according to the type of pollution in the water body; for example, in the case of nitrogen and phosphorus pollution in the water body, the purifying agent 94 can be struvite. Through the synergistic effect of the purification liquid, the purification block 43, and the purifying agent 94, the water body can be purified relatively efficiently.

[0102] According to an embodiment of the present invention, by setting the extension rod 92 to be connected to the locking block 91 and the receiving frame 93 to be connected to the extension rod 92, the floating body 1 is provided with a fixing groove 11 that matches the shape of the locking block 91 and a sliding groove 12 that matches the shape of the extension rod 92. The auxiliary purification component 9 can slide along the sliding groove 12 to the fixing groove 11 and be fixed by the locking block 91, thereby realizing the quick installation and removal function of the auxiliary purification component 9. The auxiliary purification component 9 can be quickly installed according to the purification needs, or it can be quickly disassembled for maintenance and replacement.

[0103] like Figure 10 As shown, according to another aspect of the present invention, a control method applicable to the floating water purification device described above is provided. The control method 100 may include the following operations S110-S130.

[0104] In operation S110, the floating body 1 is controlled to move to the area to be purified.

[0105] In operation S120, the drive component 2 is activated, causing the water inlet pipe 31 to alternately be in the water inlet state and the water outlet state.

[0106] In operation S130, the water suction unit 41 is activated. With the water inlet pipe 31 in the water inlet state, the water in the area to be purified enters the purification component 4 and is discharged from the water outlet 411 of the purification component 4 after purification.

[0107] According to an embodiment of the present invention, by alternating between the water inlet pipe 31 and the water outlet state, the purification component 4 does not need to be constantly immersed in water, thereby reducing the adhesion and corrosion of impurities and microorganisms in the water on the purification component 4 and extending the service life of the purification component 4.

[0108] On the other hand, since the inlet 311 alternates between the water inlet state and the water outlet state, the water inlet depth of the inlet 311 will vary within a certain range, so that water of different depths can enter the purification component 4, thereby achieving the effect of stratified purification of water of different depths by the purification component 4.

[0109] In some exemplary embodiments of the present invention, the purification process using a floating water purification device may include the following steps S210 to S250.

[0110] In step S210, the purifying liquid is filled into the container 81, the purifying block 43 and the purifying agent 94 are replaced, and the floating body 1 is placed in the water.

[0111] In step S220, during routine maintenance, the floating body 1 is allowed to float based on the buoyancy of the water, and the pumping mechanism 83 is activated to extract the purification liquid inside the container 81 to the nozzle mechanism 82, which sprays it out through multiple nozzles 821 of the nozzle mechanism 82. The purification liquid and the purification agent 94 located underwater purify the water together.

[0112] In step S230, when area patrol maintenance is required, the intermittent purification mode is entered, and the drive motor 21 of the floating body 1 is started. The drive motor 21 will drive the drive shaft 28 and the propeller blade 29 on the drive shaft 28 to rotate. The drive shaft 28 will drive the fourth shaft 22 above to rotate through the transmission belt 291 and two pulleys 292, thereby driving the first gear 23 to rotate. When the first gear 23 rotates, it drives the second shaft 6 to rotate via the second gear 24. The second shaft 6 then drives the water-absorbing parts 41 within the two side accommodating cavities 421 to rotate. At this time, the purification housing 42 has a pump-like power to actively draw in water. The second gear 24 then drives the third shaft 73 to rotate via the third gear 25. The third shaft 73 then drives the first shaft 5 to rotate via the fifth gear 27 and the fourth gear 26 on the other side. When the first shaft 5 rotates, it drives the rotating parts 32 on both sides to rotate. The rotation of the connecting parts 321 of the rotating parts 32 causes the sliding parts 34 to move along the height direction of the floating body 1 (e.g., under the support of the guide rail mechanism 33) under the guidance of the guide rail mechanism 33. Figure 1 The water inlet pipe 31 moves back and forth along the height direction of the floating body 1, as shown in the up-down direction. When the water inlet 311 of the water inlet pipe 31 moves to the underwater position, water will flow into the water inlet pipe 31 through the water inlet 311. The purification shell 42, the flexible part 36 and the water inlet pipe 31 form a channel that allows water to flow. After the water is drawn into the purification block 43 by the water suction part 41, it can be purified by the filtration of the purification block 43.

[0113] In step S240, when the pollution level is too high, the continuous purification mode is entered. The linkage motor 71 is started to drive the push rod 72 to rotate. The connecting ring 74 drives the third rotating shaft 73 to move under the limit of the limit rod 75. When the water inlet 311 of the water inlet pipe 31 is about to move to the lowest point of movement, the third gear 25 is separated from the second gear 24 and the fifth gear 27 is separated from the fourth gear 26. At this time, the water inlet assembly 3 does not work, the water inlet pipe 31 is always below the water surface, the purification assembly 4 continues to work, and the water body will continuously enter the receiving cavity 421 through the water inlet 311. After being purified by the purification block 43, the water body flows out from the water outlet 411.

[0114] In step S250, after purification is complete, the linkage motor 71 is started to rotate in reverse to reset the third rotating shaft 73, thus entering the normal intermittent purification mode. After purifying the area to be purified, the retaining rack 93 can be removed from underwater by pulling the locking block 91, and the purifying agent 94 can be replaced. The first part 422 of the purification housing 42 is removed, and the purification block 43 is taken out for cleaning and replacement. The receiving tank 81 is opened, and the purifying liquid is added to the receiving tank 81.
