Description

Technical Field

[0001] This invention relates to the field of ecological floating island technology, specifically a modular ecological floating island water purification device. Background Technology

[0002] With the acceleration of urbanization and the increasing prominence of water pollution, ecological floating island technology, as a green and sustainable water purification method, has gradually gained widespread attention. Ecological floating islands purify water quality through the combined effects of plants, microorganisms, and physical filtration by constructing artificial floating islands on the water surface. They also provide habitats for aquatic organisms and improve the aquatic ecological environment. However, traditional ecological floating islands still have many shortcomings in practical applications, such as poor structural stability, weak resistance to wind and waves, low purification efficiency, and high maintenance costs, which limit their large-scale promotion and application.

[0003] Traditional floating islands typically employ fixed or modular designs. While fixed floating islands are simple in structure, they struggle to adapt to varying aquatic environments, especially in open water with strong winds and waves, where they are prone to structural damage or capsizing. Modular designs, while offering greater flexibility and scalability, often rely on rigid connections between modules, which are susceptible to stress concentration under wind and waves, leading to breakage at joints or collision damage to the modules. Furthermore, the purification function of traditional floating islands relies primarily on passive adsorption and degradation by plants and microorganisms, resulting in low purification efficiency and difficulty in effectively removing suspended solids and deposited pollutants from the water.

[0004] In terms of energy utilization, traditional ecological floating islands typically rely on external electricity or solar energy to drive water purification equipment, which not only increases construction and operating costs but also limits the stability of energy supply. Wave energy in natural water bodies, as a clean and renewable energy source, has not yet been effectively utilized in ecological floating islands. Although some studies have attempted to combine wave energy harvesting devices with floating islands, the practical application results have been less than ideal due to problems such as low energy conversion efficiency, complex transmission structures, and poor stability.

[0005] In terms of water purification technology, traditional floating island filtration systems mostly use static filters or sedimentation tanks, which are prone to clogging due to the accumulation of pollutants, requiring frequent cleaning and maintenance. Furthermore, existing water purification components often lack efficient automatic cleaning mechanisms, causing purification efficiency to gradually decline over time. Some improved solutions attempt to combine mechanical transmission with filtration technology, but the structural design is complex and difficult to achieve efficient coordination with the floating island module, failing to meet the needs of large-scale water purification. Summary of the Invention

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a modular ecological floating island water purification device, which has the advantages of high stability, energy self-sufficiency, high purification efficiency, flexible expansion and convenient maintenance.

[0018] Based on the above technical solutions, in order to ensure that the transmission components can be stably installed on the upper plate and effectively receive the power transmitted by the energy collection components, the following technical solutions are provided.

[0019] The transmission assembly includes a transmission rack, a mounting shaft, a main rotating seat, a secondary rotating seat, and two sets of ratchet mechanisms arranged coaxially and in opposite directions.

[0021] The ratchet mechanism includes an inner ratchet, a pawl, and a spring.

A fitting is fixed to the axis of the pumping piston, and the top of the fitting is screwed to the reciprocating screw.

[0026] The beneficial effects of this invention are:

[0027] 1. To improve structural stability and resistance to wind and waves, a modular splicing design is adopted. Each floating island module is flexibly connected via shock-absorbing components, avoiding rigid collisions and effectively absorbing the impact of wind and waves, thus improving overall stability. The shock-absorbing components employ a double buffer structure of piston seats and support springs, combined with ball joint connections, allowing for multi-directional adaptive force distribution and preventing damage caused by stress concentration between modules. The floating island modules are arranged in a honeycomb pattern (circular or regular polygonal outline), enhancing overall anti-overturning capability and making them suitable for open water environments.

[0028] 2. The system efficiently utilizes wave energy to drive the water purification system, achieving energy self-sufficiency. The energy harvesting component, through a float and guide rod structure, converts water surface fluctuations into mechanical energy and transmits it to the transmission component, eliminating the need for an external power supply and thus saving energy and protecting the environment. The transmission component employs a bidirectional ratchet mechanism, converting only the unidirectional effective motion of wave energy into continuous power for the water purification component, avoiding efficiency losses caused by energy backflow and ensuring stable operation of the water purification system.

[0029] 3. Automated water purification and self-cleaning functions improve purification efficiency. The structure of the pumping piston and one-way valve enables automatic water pumping, drawing the lower layer of water to the filter cone for filtration, avoiding manual intervention and reducing maintenance costs. Cleaning components A and B automatically clean the filter cone and filter disc respectively, preventing filter clogging and maintaining long-term high-efficiency filtration. The two-stage collection design of the sludge basin and sludge cylinder intercepts large particulate impurities and suspended pollutants respectively, reducing secondary pollution and improving water purification effect.

[0030] 4. It has strong modularity and scalability, and wide applicability. The floating island modules can be flexibly spliced ​​together and the scale can be adjusted according to the size of the water area. It is suitable for various scenarios such as lakes, rivers, and landscape water bodies. The planting tube design can plant aquatic plants, which, combined with mechanical water purification, form a "plant-machine" synergistic purification, enhance the ecological restoration function, and at the same time improve the landscape value.

[0031] 5. Easy to maintain and long service life. The upper plate is designed to be detachable, which makes it easy to inspect and clean the transmission components and water purification components. The planting tube can be removed separately, which makes it easy to replace or prune the plants and reduce long-term operating costs. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figures 1-3 , Figure 9 A modular ecological floating island water purification device includes a floating island module 1 and a shock-absorbing component 2 assembled around the floating island module 1. Multiple sets of floating island modules 1 include a mounting base 11 and a floating ring 12 fixedly installed to the bottom outer edge of the mounting base 11. The mounting bases 11 in each set of floating island modules 1 are spliced ​​and combined by the shock-absorbing component 2.

[0047] It also includes the matching combination of energy harvesting component 3, transmission component 4, and water purification component 5, which are assembled on the mounting base 11 and kept together. The energy harvesting component 3 is used to collect the energy generated by water surface fluctuations and transmit it to the transmission component 4.

[0048] The water purification assembly 5 includes a sludge collection basin 51, a pumping cylinder 52, a sludge collection tube 53, and a pumping piston 54, a cleaning assembly A 55, and a cleaning assembly B 56 that maintain a linkage. The sludge collection basin 51 is fixedly installed on the mounting base 11 and is coaxially connected to the pumping cylinder 52. A filter cone 511 with a high center and low outer edge is provided on the sludge collection basin 51. The cleaning assembly A 55 is rotatably installed on the top of the pumping cylinder 52 and cooperates with the filter cone 511. The transmission assembly 4 is connected to the cleaning assembly A 56. 55. A power connection is established. An isolation disc 521 is fixedly connected to the water pump 52. A water pumping piston 54 is assembled into the water pump 52 and arranged above the isolation disc 521. A one-way valve 57 is installed on both the isolation disc 521 and the water pumping piston 54. A water filter disc 522 extending underwater is installed at the bottom of the water pump 52. A sludge collection cylinder 53 is fixedly installed below the water filter disc 522. A sludge cleaning component B56 is rotatably installed at the axis of the water filter disc 522 and cooperates with the water filter disc 522.

[0049] The floating island module 1 adopts a combination of mounting base 11 and float ring 12, which ensures stable floating on the water surface while enabling the stable installation of energy collection component 3, transmission component 4, water purification component 5 and other components. Through the shock absorption component 2, multiple floating island modules 1 can be spliced ​​and combined to form a larger-scale ecological floating island, thereby improving the overall structural stability and wind and wave resistance. The design of the shock absorption component 2 can avoid rigid contact between adjacent floating island modules 1, providing good shock resistance when facing wind and waves, and preventing collision damage to the floating island module 1 and its components.

[0050] To enhance the aesthetic appeal of the constructed ecological floating island, the outer contours of the floating ring 12 and the mounting base 11 can be set as circles or regular polygons, forming an ecological floating island with a honeycomb-like structure.

[0051] The energy collection component 3 can operate independently of the floating island module 1 to receive the kinetic energy of wind and waves and transmit it to the transmission component 4. The transmission component 4 can integrate and stabilize the received kinetic energy to stably transmit the power to the water purification component 5, thereby driving the water purification component 5 to automatically purify the nearby water.

[0052] For the water purification component 5, the sludge collection basin 51 is located above the water surface to prevent the collected dirt from spreading back into the water. When the transmission component 4 drives the pumping piston 54, cleaning component A 55, and cleaning component B 56 to run according to the set requirements, the up and down movement of the pumping piston 54 can draw the surrounding water through the sludge collection cylinder 53 and the filter disc 522 into the pumping cylinder 52. Larger impurities in the water will be intercepted by the filter disc 522 and moved downwards to prevent them from entering the pumping cylinder 52 and clogging the one-way valve 57. Under the continuous operation of the cleaning component B 56, the impurities attached to the bottom of the filter disc 522 can be cleaned and collected into the sludge collection cylinder 53.

[0053] As the pumping piston 54 moves upward, the negative pressure generated draws water into the pumping cylinder 52 and into the space above the isolation plate 521 through the one-way valve 57 on the isolation plate 521. The water above the pumping piston 54 is blocked by the one-way valve 57 on the pumping piston 54 to prevent it from falling back below the pumping piston 54. Finally, the water is pumped upward and flows into the collection basin 51.

[0054] As the pumping piston 54 moves downward, it squeezes the water below it, causing it to flow through the one-way valve 57 on the pumping piston 54 to the top of the pumping piston 54. The one-way valve 57 on the isolation plate 521 can prevent the water from flowing back and falling back below the isolation plate 521.

[0055] When water flows from the top of the pumping cylinder 52 to the outside of the collection basin 51, the filter cone 511 on it can ensure that the water falls freely along its surface to the outer edge. The filter cone 511 can filter the water and return it to the water. The fine impurities carried can be intercepted by the filter cone 511 and collected into the collection basin 51 under the continuous operation of the cleaning component A55, thus achieving the final purpose of water purification.

[0056] Example 2

[0057] Please see Figures 3-4 To ensure that the floating island module 1 can float stably on the water surface and to enable the stable assembly of components such as the energy collection component 3, transmission component 4, and water purification component 5 on it, the following technical solutions are provided.

[0058] The mounting base 11 includes an assembly ring 111, a lower pad 112, an upper pad 113, and a connecting cylinder 114. The float ring 12 is nested and fixed below the assembly ring 111. The lower pad 112 is fixed to the inner side of the assembly ring 111. The energy-gathering component 3 is assembled on the lower pad 112 and arranged in a ring array. The upper pad 113 is arranged above the lower pad 112 and fixed to the lower pad 112 through the connecting cylinder 114. The sludge collection basin 51 is fixedly installed on the lower pad 112 and arranged inside the connecting cylinder 114. The transmission component 4 is assembled on the upper pad 113.

[0059] The assembly ring 111 ensures the accurate positioning and effective installation of the float ring 12, while the lower pad 112 ensures the stable assembly of the energy-gathering component 3 and the water purification component 5 on the floating island module 1. The connecting cylinder 114 can raise the upper pad 113 to a specific height. The upper pad 113 is detachably assembled to the top of the connecting cylinder 114 to facilitate the installation of the transmission component 4 and its linkage with the energy-gathering component 3 and the water purification component 5, and also to facilitate the disassembly and cleaning of the water purification component 5.

[0060] To improve the water purification effect and aesthetics of ecological floating islands, the following further technical solutions are provided.

[0061] The lower pad plate 112 is also evenly provided with multiple sets of assembly through holes 1121 arranged on the outside of the connecting cylinder 114. The floating island module 1 also includes a planting cylinder 13 fixedly installed in the assembly through hole 1121. The bottom of the planting cylinder 13 is provided with a connecting hole 131.

[0062] The planting tube 13 is used to plant aquatic plants that can purify water, and is installed in the assembly through hole 1121 in a detachable manner for easy assembly and disassembly. The connecting hole 131 at the bottom of the planting tube 13 is located below the water surface, which allows the roots of aquatic plants to pass through the connecting hole 131 into the water, and also allows water to enter the inner side through the connecting hole 131 to ensure the stable growth of aquatic plants.

[0063] Example 3

[0064] Please see Figures 1-2 , Figure 5 To ensure that the shock absorption component 2 can effectively connect to the floating island module 1 and provide effective shock absorption, the following technical solution is provided.

[0065] Multiple sets of ball joint seats 1111 arranged in a ring array are fixedly connected to the outer periphery of the assembly ring 111. The shock absorption assembly 2 includes an assembly cylinder 21, a piston rod 22, an end cap 23, a piston seat 24, and a support spring 25. The end cap 23 is fixedly installed on the inner end of the assembly cylinder 21. The piston rod 22 passes through the end cap 23. Throttling holes 211 are opened on both side walls of the assembly cylinder 21. The piston seat 24 is assembled into the assembly cylinder 21 and fixedly connected to the inner end of the piston rod 22. Connecting discs 26 are fixedly connected to the outer ends of the assembly cylinder 21 and the piston rod 22, respectively. The support spring 25 is sleeved around the assembly cylinder 21 and the piston rod 22 and is fixedly connected to the two sets of connecting discs 26. A ball joint head 261 that matches the ball joint seat 1111 is fixedly connected to the outer end of the connecting disc 26.

[0066] The matching combination of ball joint head 261 and ball joint seat 1111 enables the ball joint connection between the assembly ring 111 and the shock absorption component 2 in the floating island module 1, so as to receive and stably transmit forces in all directions. Due to the connection between the throttling orifice 211 and the external environment in the assembly cylinder 21, air or water can be used as the damping medium. During the extension and retraction movement of the piston seat 24 and the piston rod 22, the damping medium on one side of the piston seat 24 can be squeezed out from the throttling orifice 211, while the throttling orifice 211 on the other side can draw in air or water from the external environment. Since the orifice 211 has a small diameter, it can prevent impurities in the water from entering and restrict the flow state of the damping medium to achieve the shock absorption effect. The support spring 25 plays the role of storing force during the extension and retraction movement, and the force is slowly released through the assembly cylinder 21, piston rod 22, and piston seat 24.

[0067] Example 4

[0068] Please see Figures 1-3 , Figure 6 To ensure that the energy harvesting component 3 is stably installed on the lower pad 112 and effectively receives the kinetic energy of wind and waves and transmits it to the transmission component 4, the following technical solution is provided.

[0069] The energy collection component 3 includes a hinge seat 31, a guide sleeve 32, a guide rod 33, a float 34, and a slide 35. The hinge seat 31 is fixed to the lower pad 112 and is hinged to the guide sleeve 32. The guide rod 33 is slidably inserted into the guide sleeve 32 and the outer end is fixed to the float 34 that floats to the water surface. The upper pad 113 has radially distributed guide grooves 1131. The slide 35 is slidably installed in the guide grooves 1131 and is hinged to the inner end of the guide rod 33.

[0070] The combination of the hinge seat 31 and the guide sleeve 32 enables the guide rod 33 to flip and slide axially. When wind and waves act on the float 34, the guide rod 33 can push the slide 35 to slide stably. The design of the guide groove 1131 can ensure that the slide 35 slides stably in the radial direction. The motion generated by the slide 35 drives the transmission component 4 to run.

[0071] To avoid spatial movement interference between the mounting base 11 and the energy collection component 3, clearance openings A1122 are evenly provided on the lower pad 112 so that the float 34 and guide rod 33 can move normally with the waves. A clearance opening B1141 is provided on the side wall of the connecting cylinder 114 so that the guide rod 33 can pass through the connecting cylinder 114 normally and be hinged to the slide block 35.

[0072] Example 5

[0073] Please see Figure 3 , Figures 6-8 To ensure that the transmission component 4 can be stably installed on the upper pad 113 and effectively receive the power transmitted by the energy collection component 3, the following technical solution is provided.

[0074] The transmission assembly 4 includes a transmission rack 41, a mounting shaft 42, a main rotating seat 43, a secondary rotating seat 44, and two sets of ratchet mechanisms 45 arranged coaxially and in opposite directions. The main rotating seat 43 is rotatably mounted on the upper pad 113. The mounting shaft 42 and the secondary rotating seat 44 are both coaxially rotatably connected to the main rotating seat 43. The two sets of ratchet mechanisms 45 are both assembled on the mounting shaft 42 and are linked with the main rotating seat 43 and the secondary rotating seat 44 respectively. The main rotating seat 43 and the secondary rotating seat 44 are respectively fixedly connected to the drive gear 431 and the transmission gear 441. The transmission rack 41 is fixedly connected to the slide 35 and meshes with the drive gear 431. The water purification assembly 5 is poweredly connected to the transmission gear 441.

[0075] When the float 34 in the energy-collecting component 3 rises with the waves, it pushes the slide 35 and the transmission rack 41 fixed thereon towards the axis, thereby driving the drive gear 431 and the main rotating seat 43 to rotate forward. At this time, the forward-rotating main rotating seat 43 can drive the mounting shaft 42 to rotate synchronously forward through the matching ratchet mechanism 45, thus transmitting power to another set of ratchet mechanisms 45 and the auxiliary rotating seat 44. When the float 34 in the energy-collecting component 3 falls back, it pulls the slide 35 and the transmission rack 41 fixed thereon away from the axis, thereby driving the drive bevel gear and the main rotating seat 43 to rotate in the opposite direction. The reverse-rotating main rotating seat 43 cannot transmit power to the mounting shaft 42 through the corresponding ratchet mechanism 45. At this time, the mounting shaft 42 is stationary and the transmission of power to the auxiliary rotating seat 44 and the transmission gear 441 is canceled. This design can avoid bidirectional power transmission during the continuous up-and-down movement of the float 34, thus avoiding interference with the normal operation of the water purification component 5.

[0076] When the main rotating seat 43 drives the mounting shaft 42 to operate normally via the matching ratchet mechanism 45, it can drive the auxiliary rotating seat 44 and the transmission gear 441 to transmit power unidirectionally to the water purification component 5 through another set of ratchet mechanisms 45. That is, the power of the mounting shaft 42 can only be transmitted unidirectionally to the water purification component 5, and the movement of the water purification component 5 is prevented from driving the mounting shaft 42 to rotate in the opposite direction. This design can stably operate each set of energy-collecting components 3 and transmission components 4 deployed in cooperation and independently transmit power unidirectionally to the water purification component 5, avoiding mutual interference in the operation of each set of energy-collecting components 3 and transmission components 4 due to the setting of the water purification component 5.

[0077] To ensure that the two sets of ratchet mechanisms 45 can be stably assembled between the mounting shaft 42 and the main rotating seat 43 and the auxiliary rotating seat 44, and to achieve unidirectional power transmission, the following technical solution is provided.

[0078] The ratchet mechanism 45 includes an inner ratchet 451, a pawl 452, and a spring 453. The inner ratchet 451 in the two sets of ratchet mechanisms 45 are respectively disposed in the main rotating seat 43 and the auxiliary rotating seat 44. The pawl 452 is rotatably mounted to the periphery of the mounting shaft 42 and maintains engagement with the corresponding inner ratchet 451. The spring 453 is assembled between the mounting shaft 42 and the pawl 452.

[0079] The spring 453 can push the corresponding pawl 452 outward to engage with the corresponding inner ratchet 451. When the main rotating seat 43 rotates in the forward direction, the inner ratchet 451 can push the corresponding pawl 452 and the mounting shaft 42 to rotate synchronously. When the main rotating seat 43 rotates in the reverse direction, the inner ratchet 451 and the corresponding pawl 452 are in a slipping state and cannot transmit power.

[0080] When the mounting shaft 42 drives the pawl 452, which cooperates with the auxiliary rotating seat 44, to rotate in the forward direction, since the two sets of ratchet mechanisms 45 are arranged in opposite directions, the power can drive the external inner ratchet 451, the auxiliary rotating seat 44, and the transmission gear 441 to operate stably through the internal pawl 452, thereby driving the water purification component 5 to operate continuously. When the water purification component 5 drives the transmission gear 441 and the auxiliary rotating seat 44 to operate in the reverse direction, the internal ratchet 451 and the corresponding pawl 452 are in a slipping state and cannot transmit the power in the reverse direction to the mounting shaft 42.

[0081] Example 6

[0082] Please see Figure 3 , Figures 9-11 To ensure that the cleaning component A55 can be stably installed on the top of the pumping cylinder 52 and effectively clean the debris on the filter cone 511, while also achieving power connection with the transmission component 4 and the pumping piston 54, the following technical solution is provided.

[0083] The cleaning assembly A55 includes a rotating disk A551, a geared disk 552, a scraper A553, and a reciprocating screw 554. The rotating disk A551 is rotatably mounted to the top of the pumping cylinder 52 and is coaxially fixed to the geared disk 552. The geared disk 552 is rotatably mounted to the upper pad 113 and is engaged with the transmission gear 441. The scraper A553 includes multiple sets fixed to the periphery of the rotating disk A551 and in contact with the upper surface of the filter cone disk 511. The reciprocating screw 554 is fixed to the axis of the rotating disk A551 and arranged in the pumping cylinder 52. A mounting device 541 is fixed to the axis of the pumping piston 54. The top of the mounting device 541 is screwed to the reciprocating screw 554. The outer wall of the pumping cylinder 52 has an outlet hole 523 arranged above the sludge collection basin 51.

[0084] To ensure the operational stability of each set of scraper blades A553, a reinforcing ring 555 is fixed to each scraper blade to stably position each set of scraper blades A553.

[0085] When the transmission assembly 4 drives the gear disc 552 and the entire cleaning assembly A55, the scraper A553 on it can effectively clean the filter cone disc 511. The continuous operation of the reciprocating screw 554 can drive the assembly 541 and the pumping piston 54 to periodically rise and fall within the stroke range. This pumps the water at the bottom of the pumping cylinder 52 upwards and transfers it to the sludge collection basin 51 through the water outlet 523.

[0086] A detachable protective cover 1132 is installed on the upper pad 113 to enclose components such as the transmission assembly 4 and the large gear disc 552, ensuring stable operation of each component. A clearance opening C1123 is provided at the axis of the lower pad 112 to allow the water pump 52 to pass through the lower pad 112 normally and to allow water passing through the filter cone 511 to leak down to the water surface through the clearance opening C1123.

[0087] To ensure that the cleaning component B56 can be stably installed on the filter disc 522 at the top and bottom of the pumping cylinder 52, and to effectively clean the debris on the filter disc 522, while also achieving a power connection with the pumping piston 54, the following technical solution is provided.

[0088] The cleaning assembly B56 includes a rotating disk B561 and scraper bars B562. The rotating disk B561 is rotatably mounted to the axis of the filter disc 522. The scraper bars B562 include multiple sets fixed to the periphery of the rotating disk B561 and kept in contact with the lower surface of the filter disc 522. The bottom of the pumping piston 54 is fixedly connected to a guide shaft 542 and a threaded rod 543 arranged coaxially. The guide shaft 542 is slidably inserted into the axis of the isolation disc 521. The threaded rod 543 is fixed to the bottom of the guide shaft 542 and is screwed into the axis of the rotating disk B561. The top side wall of the sludge collection cylinder 53 is provided with a water inlet hole 531.

[0089] The water inlet 531 ensures that impurities carried by nearby water enter the collection cylinder 53, are filtered by the filter disc 522, and then transported in the pumping cylinder 52, thereby trapping large-volume impurities in the collection cylinder 53 for collection.

[0090] The cooperation between the guide shaft 542 and the isolation disc 521 ensures the stable lifting and lowering movement of the pumping piston 54 and enables the threaded rod 543 to move synchronously with the pumping piston 54. In turn, the threaded rod 543 drives the cleaning component B56 to rotate periodically, so as to effectively clean the filter disc 522 with the help of the scraper B562 on it.
