Description

Technical Field

[0001] The present invention relates to the technical field of ecological floating islands, and in particular to a modular ecological floating island water purification device. Background Art

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

[0003] Traditional ecological floating islands typically adopt fixed or modular designs. While fixed floating islands are simple in structure, they struggle to adapt to the demands of diverse water environments, especially in open waters with strong winds and waves, where they are prone to structural damage or capsizing. While modular designs offer increased flexibility and scalability, the connections between modules are often rigid, which can easily lead to stress concentration under the influence of wind and waves, causing fractures at the connections or damage to the modules due to collisions. 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 matter and sediment pollutants from the water.

[0004] In terms of energy utilization, traditional ecological floating islands typically rely on external electricity or solar energy to power 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, a clean, renewable energy source, has yet to be effectively utilized in ecological floating islands. Although some research has attempted to integrate wave energy harvesting devices with floating islands, practical applications have been less than ideal due to issues such as low energy conversion efficiency, complex transmission structures, and poor stability.

[0005] In terms of water purification technology, traditional floating island filtration systems often use static filters or sedimentation tanks, which are prone to clogging due to pollutant accumulation and require frequent cleaning and maintenance. Furthermore, existing water purification components often lack efficient automatic cleaning mechanisms, resulting in a gradual decline in purification efficiency over time. Some improved solutions attempt to combine mechanical transmission and filtration technologies, but the structural design is complex and difficult to achieve efficient coordination with the floating island modules, making them unable to meet the needs of large-scale water purification.

[0026] Beneficial effects of the present invention:

[0027] 1. To enhance structural stability and wave resistance, the modular design utilizes flexible connections between floating island modules via shock-absorbing components, preventing rigid collisions and effectively absorbing wave impacts, enhancing overall stability. The shock-absorbing components utilize a dual-buffer structure consisting of a piston seat and support spring, combined with a ball-joint connection, for multi-directional adaptive load response, preventing damage caused by stress concentration between modules. The floating island modules are arranged in a honeycomb pattern (circular or regular polygonal outlines) to enhance overall anti-overturning capabilities, making them suitable for open water environments.

[0028] 2. The water purification system efficiently utilizes wave energy to achieve energy self-sufficiency. The energy harvesting component, through a buoy and guide rod structure, converts water surface fluctuations into mechanical energy and transmits it to the transmission component, eliminating the need for external power supply and promoting energy conservation and environmental protection. The transmission component utilizes 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 back-transfer and ensuring stable operation of the water purification system.

[0029] 3. Automated water purification and self-cleaning functions improve purification efficiency. The pumping piston and one-way valve structure automatically pump water from the lower layer to the filter cone for filtration, eliminating 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 dual-stage collection design of the collection basin and collection drum respectively intercepts large particles and suspended pollutants, reducing secondary contamination and improving water purification.

[0030] 4. The modular system has strong scalability and wide applicability. The floating island modules can be flexibly spliced ​​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 be used to plant aquatic plants. Combined with mechanical water purification, it forms a "plant-machine" collaborative purification, enhances the ecological restoration function, and improves the landscape value.

[0031] 5. Easy maintenance and long service life. The upper pad is detachable, which is convenient for inspection and cleaning of the transmission components and water purification components. The planting tube can be taken out separately, which is convenient for replacing or pruning plants and reducing long-term operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1-Figure 3 、 Figure 9 A modular ecological floating island water purification device includes a floating island module 1 and a shock-absorbing component 2 assembled to the periphery of the floating island module 1. Multiple groups of floating island modules 1 include a mounting base 11 and a floating ring 12 fixedly mounted to the bottom outer edge of the mounting base 11. The mounting base 11 in each group of floating island modules 1 is spliced ​​and combined through the shock-absorbing component 2.

[0047] It also includes an energy collection component 3, a transmission component 4, and a water purification component 5 that are assembled on the mounting base 11 and maintain a matching combination. The energy collection component 3 is used to collect energy generated by water surface fluctuations and transmit it to the transmission component 4.

[0048] The water purification component 5 includes a sewage collecting basin 51, a water pumping cylinder 52, a sewage collecting cylinder 53, a water pumping piston 54, a sewage cleaning component A55, and a sewage cleaning component B56 that maintain a linkage combination. The sewage collecting basin 51 is fixedly installed on the mounting base 11 and is coaxially fixed to the water pumping cylinder 52. A water filter cone 511 with a high center and a low outer edge is provided on the sewage collecting basin 51. The sewage cleaning component A55 is rotatably installed on the top of the water pumping cylinder 52 and cooperates with the water filter cone 511. The transmission component 4 is connected to the sewage cleaning component A55. 55 power connection, an isolation disk 521 is fixedly connected to the water pumping cylinder 52, the water pumping piston 54 is assembled into the water pumping cylinder 52 and arranged above the isolation disk 521, and a one-way valve 57 is assembled on the isolation disk 521 and the water pumping piston 54. The bottom of the water pumping cylinder 52 is equipped with a water filter disc 522 extending underwater, the sewage collecting cylinder 53 is fixedly installed below the water filter disc 522, and the sewage cleaning component B56 is rotatably installed to 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 an installation base 11 and a float ring 12, which can ensure its stable floating on the water surface while realizing the stable installation of the energy collection component 3, the transmission component 4, the water purification component 5 and other components. Through the shock-absorbing component 2, multiple groups of floating island modules 1 can be spliced ​​and combined to form a larger-scale ecological floating island, so as to improve the overall structural stability and wind and wave resistance. The design of the shock-absorbing component 2 can avoid rigid contact between adjacent floating island modules 1, has good seismic effect when facing wind and waves, and avoids collision damage to the floating island module 1 and its components.

[0050] In order to improve the aesthetic effect of the constructed ecological floating island, the outer edge contours of the floating ring 12 and the mounting base 11 can be set to be circular or regular polygonal, forming an ecological floating island with a honeycomb structure.

[0051] The energy harvesting 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 output the power to the water purification component 5, driving the water purification component 5 to operate and realize automatic purification of nearby water bodies.

[0052] As for the water purification component 5, the sewage collecting basin 51 is arranged above the water surface to prevent the collected sewage from spreading back into the water. When the transmission component 4 drives the water pumping piston 54, the sewage cleaning component A55, and the sewage cleaning component B56 to operate according to the set requirements, the up and down movement of the water pumping piston 54 can draw the surrounding water into the water pumping cylinder 52 through the sewage collecting cylinder 53 and the water filter disc 522. The larger impurities in the water will be intercepted by the water filter disc 522 to the bottom to prevent them from entering the water pumping cylinder 52 and clogging the one-way valve 57. Under the continuous operation of the sewage cleaning component B56, the impurities attached to the bottom of the water filter disc 522 can be cleaned and collected in the sewage collecting cylinder 53.

[0053] During the upward movement of the water pumping piston 54, the negative pressure generated will suck the water into the water pumping cylinder 52 and enter the top of the isolation plate 521 through the one-way valve 57 provided on the isolation plate 521. The water above the water pumping piston 54 is blocked by the one-way valve 57 provided on the water pumping piston 54 to prevent it from falling back under the water pumping piston 54, and finally the water is pumped upward and flows toward the sewage collection basin 51.

[0054] During the downward movement of the water pumping piston 54, the water below it is squeezed, causing it to flow to the top of the water pumping piston 54 through the one-way valve 57 provided on the water pumping piston 54, while the one-way valve 57 provided on the isolation plate 521 can prevent the water from flowing back and falling under the isolation plate 521.

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

[0056] Example 2

[0057] See also Figure 3-Figure 4 In order to ensure that the floating island module 1 can float stably on the water surface and realize the stable assembly of components such as the energy harvesting component 3, the transmission component 4, and the water purification component 5 thereon, 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 tube 114. The floating ring 12 is nested and fixed under the assembly ring 111. The lower pad 112 is fixed to the inner side of the assembly ring 111. The energy harvesting assembly 3 is assembled on the lower pad 112 and distributed in a circular array. The upper pad 113 is arranged above the lower pad 112 and fixed to the lower pad 112 through the connecting tube 114. The sewage collecting basin 51 is fixedly mounted on the lower pad 112 and arranged on the inner side of the connecting tube 114. The transmission assembly 4 is assembled on the upper pad 113.

[0059] The setting of the assembly ring 111 can ensure the precise positioning and effective installation of the float ring 12, and the setting of the lower pad 112 can ensure the stable assembly of the energy harvesting component 3 and the water purification component 5 on the floating island module 1. The connecting tube 114 can lift the upper pad 113 to a specific height. The upper pad 113 is assembled to the top of the connecting tube 114 in a detachable manner to facilitate the installation of the transmission component 4 and the linkage combination with the energy harvesting component 3 and the water purification component 5, and also facilitate the disassembly and cleaning of the water purification component 5.

[0060] In order to improve the water purification effect and aesthetics of the ecological floating island, the following further technical solutions are provided.

[0061] The lower pad 112 is evenly provided with a plurality of assembly through holes 1121 arranged outside the connecting tube 114 . The floating island module 1 further includes a planting tube 13 fixedly installed in the assembly through hole 1121 , and a connecting hole 131 is provided at the bottom of the planting tube 13 .

[0062] Planting tube 13 is used to plant water-purifying aquatic plants and is removably mounted in assembly hole 1121, making it easy to install and remove. A connecting hole 131 at the bottom of planting tube 13 is located below the water surface, allowing the roots of the aquatic plants to pass through connecting hole 131 and enter the water. This also facilitates the flow of water through connecting hole 131, ensuring the stable growth of the aquatic plants.

[0063] Example 3

[0064] See also Figure 1-Figure 2 、 Figure 5 In order to ensure that the shock absorbing assembly 2 can achieve effective connection to the floating island module 1 and provide effective shock absorbing effect, the following technical solutions are provided.

[0065] The periphery of the assembly ring 111 is fixedly connected to multiple groups of ball joint seats 1111 distributed in a ring array. The shock absorber assembly 2 includes an assembly cylinder 21, a piston rod 22, an end cover 23, a piston seat 24, and a support spring 25. The inner end of the assembly cylinder 21 is fixedly installed with the end cover 23, and the piston rod 22 is arranged through the end cover 23. A throttle hole 211 is provided on the side walls at both ends of the assembly cylinder 21. The piston seat 24 is assembled into the assembly cylinder 21 and fixed to the inner end of the piston rod 22. The outer ends of the assembly cylinder 21 and the piston rod 22 are respectively fixed with connecting plates 26. The support spring 25 is sleeved on the outer periphery of the assembly cylinder 21 and the piston rod 22 and remains fixed with the two groups of connecting plates 26. The outer end of the connecting plate 26 is fixed with a ball joint head 261 that is matched with the ball joint seat 1111.

[0066] The matching combination of the ball joint head 261 and the ball joint seat 1111 can realize the ball joint connection between the assembly ring 111 in the floating island module 1 and the shock absorbing component 2, so as to receive the force in various directions and transmit it stably. Due to the connection between the throttle hole 211 and the external environment in the assembly cylinder 21, air or water can be used as the damping medium. During the process of the piston seat 24 and the piston rod 22 being subjected to force and telescopic movement, the damping medium on one side can be squeezed out from the throttle hole 211 through the piston seat 24, while the air or water in the external environment can be drawn in through the throttle hole 211 on the other side. Since the aperture of the throttle hole 211 is small, it can prevent impurities in the water body from entering and limit the flow state of the damping medium to achieve a shock absorbing effect. The support spring 25 plays the role of storing the force during the telescopic movement, and realizes the slow release of the force through the assembly cylinder 21, the piston rod 22 and the piston seat 24.

[0067] Example 4

[0068] See also Figure 1-Figure 3 、 Figure 6 In order to ensure that the energy harvesting assembly 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 assembly 4, the following technical solution is provided.

[0069] The energy harvesting assembly 3 includes an articulated seat 31, a guide sleeve 32, a guide rod 33, a float 34, and a slide 35. The articulated seat 31 is fixed to the lower pad 112 and remains 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 floating on the water surface. The upper pad 113 is provided with radially distributed guide grooves 1131. The slide 35 is slidably installed in the guide grooves 1131 and remains hinged to the inner end of the guide rod 33.

[0070] The combination of the articulated seat 31 and the guide sleeve 32 can realize the flipping and axial sliding of the guide rod 33. 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, and the movement generated by the slide 35 drives the transmission component 4 to operate.

[0071] In order to avoid spatial movement interference between the mounting base 11 and the energy harvesting assembly 3, clearance openings A1122 are evenly opened on the lower pad 112 to allow the float 34 and the guide rod 33 to move normally with the wind and waves. A clearance opening B1141 is opened on the side wall of the connecting tube 114 to allow the guide rod 33 to pass through the connecting tube 114 normally to achieve articulation with the slide 35.

[0072] Example 5

[0073] See also Figure 3 、 Figure 6-Figure 8 In order 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, an installation shaft 42, a main rotating seat 43, an auxiliary rotating seat 44 and two groups of ratchet mechanisms 45 that are coaxially arranged in opposite directions. The main rotating seat 43 is rotatably installed on the upper pad 113. The installation shaft 42 and the auxiliary rotating seat 44 are both coaxially rotated and connected to the main rotating seat 43. The two groups of ratchet mechanisms 45 are both assembled on the installation shaft 42 and are respectively linked to the main rotating seat 43 and the auxiliary rotating seat 44. The main rotating seat 43 and the auxiliary rotating seat 44 are respectively fixed with a driving gear 431 and a transmission gear 441. The transmission rack 41 is fixed to the slide 35 and remains engaged with the drive gear 431. The water purification assembly 5 maintains a power connection with the transmission gear 441.

[0075] When the float 34 in the energy harvesting assembly 3 rises with the wind and waves, it pushes the slide 35 and the transmission rack 41 fixed thereto toward the axis, thereby driving the drive gear 431 and the main rotating seat 43 to rotate forward. The forward-rotating main rotating seat 43 can then drive the mounting shaft 42 to rotate forward synchronously via the corresponding ratchet mechanism 45, thereby transmitting power to the other set of ratchet mechanisms 45 and the auxiliary rotating seat 44. When the float 34 in the energy harvesting assembly 3 falls back, it pulls the slide 35 and the transmission rack 41 fixed thereto 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 is unable to transmit power to the mounting shaft 42 via the corresponding ratchet mechanism 45. At this time, the mounting shaft 42 is stationary, and power transmission to the auxiliary rotating seat 44 and transmission gear 441 is canceled. This design prevents bidirectional power transmission during the continuous ups and downs of the float 34, thereby preventing interference with the normal operation of the water purification assembly 5.

[0076] When the main rotating seat 43 drives the installation shaft 42 through the supporting ratchet mechanism 45 to operate normally, another set of ratchet mechanisms 45 can drive the auxiliary rotating seat 44 and transmission gear 441 to transmit power to the water purification component 5 in a one-way manner. In other words, the power of the installation shaft 42 can only be transmitted in one direction to the water purification component 5, and the movement of the water purification component 5 can be prevented from driving the installation shaft 42 in the opposite direction. This design ensures the stable operation of each set of energy harvesting components 3 and transmission components 4, and transmits power in a one-way and independent manner to the water purification component 5, avoiding mutual interference between the operation of each set of energy harvesting components 3 and transmission components 4 due to the installation of the water purification component 5.

[0077] In order 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 ratchets 451 in the two sets of ratchet mechanisms 45 are respectively arranged in the main rotating seat 43 and the auxiliary rotating seat 44. The pawl 452 is rotatably installed to the periphery of the mounting shaft 42 and remains engaged 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 to spread outward and engage with the corresponding inner ratchet 451. When the main rotating seat 43 rotates forward, the inner ratchet 451 can push the corresponding pawl 452 and the mounting shaft 42 to operate synchronously. When the main rotating seat 43 rotates reversely, the inner ratchet 451 and the corresponding pawl 452 inside it are in a slipping state and cannot transmit power.

[0080] When the installation shaft 42 drives the pawl 452 that cooperates with the auxiliary rotating seat 44 to rotate forward, since the two sets of ratchet mechanisms 45 remain arranged in reverse, the power can drive the external inner ratchet 451 and 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 achieve continuous operation. 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 follow-up inner ratchet 451 and the corresponding pawl 452 are in a slipping state and cannot transmit power in reverse to the installation shaft 42.

The top of the assembly set 541 is kept in rotational connection with the reciprocating screw 554. The outer wall of the water pumping cylinder 52 is provided with a water outlet hole 523 arranged above the sewage collecting basin 51.

[0084] In order to ensure the operational stability of each group of scraper strips A553, a reinforcing ring 555 is fixed to each scraper strip to stably position each group of scraper strips A553.

[0085] When the transmission assembly 4 drives the toothed disc 552 and the entire cleaning assembly A55, the scraper strips A553 thereon effectively clean the water filter cone 511. The continuous operation of the reciprocating screw 554 drives the assembly 541 and the pumping piston 54 to periodically move up and down within the travel range, thereby pumping water from the bottom of the pumping cylinder 52 upward and transferring it to the waste collection basin 51 through the water outlet 523.

[0086] A removable protective cover 1132 is attached to the upper base plate 113 to enclose components such as the transmission assembly 4 and the large gear plate 552, ensuring stable operation. A clearance opening C1123 is provided at the axis of the lower base plate 112 to allow the pumping cylinder 52 to pass through the lower base plate 112 and allow water passing through the filter cone 511 to drain to the surface through the clearance opening C1123.

The scraper B562 includes multiple groups fixed to the outer periphery of the rotating disk B561 and kept in contact with the lower surface of the water filter disk 522.

A water inlet hole 531 is provided on the top side wall of the sewage collecting cylinder 53.

[0089] The setting of the water inlet hole 531 can ensure that the impurities carried by the nearby water body enter the sewage collection barrel 53, and are filtered and processed by the water filter disc 522 before being transported to the water pump 52, thereby allowing large-volume impurities to be trapped and collected in the sewage collection barrel 53.

[0090] The cooperation between the guide shaft 542 and the isolation disc 521 can ensure the stable lifting and lowering movement of the water pumping piston 54, and realize the synchronous movement of the threaded rod 543 and the water pumping piston 54, and then the threaded rod 543 drives the cleaning component B56 to perform periodic reciprocating rotation, so as to effectively clean the water filter disc 522 with the help of the scraper B562 thereon.
