Description

Technical Field

[0001] This invention relates to the field of ecological floating island technology, and in particular to a honeycomb-type ecological floating island device and its usage method. Background Technology

[0002] Ecological floating islands, also known as artificial floating beds or ecological floating beds, are a type of artificial floating island designed for eutrophic water quality. Utilizing ecological engineering principles, they degrade COD, nitrogen, and phosphorus in the water. Primarily composed of aquatic plants, they employ soilless cultivation techniques, using polymer materials as carriers and substrates. By leveraging interspecies symbiotic relationships and fully utilizing the ecological niches and nutrient niches of the water body, they establish highly efficient artificial ecosystems to reduce the pollution load in water bodies.

[0003] Most existing ecological floating islands are rectangular and flat, which prevents plants from forming three-dimensional ecological niche stratification, thereby reducing the utilization rate of water space. The lack of gradient differences in underwater light, root distribution and water flow environment is also unfavorable for the habitat and reproduction of aquatic organisms in different water layers, ultimately affecting the integrity of artificial ecosystems. At the same time, plants on the same horizontal plane tend to overlap densely, resulting in poor sunlight utilization. Insufficient light will further inhibit the photosynthesis and growth of aquatic plants, ultimately weakening the floating island's ability to purify water.

[0004] The area of ​​existing ecological floating islands is mostly pre-designed and lacks flexible adjustment space, making it difficult to adapt to the phased expansion needs of irregular waters or management areas. In addition, fixed-size floating islands take up a lot of space and are inconvenient to transport. Excessive splicing can also lead to a loose overall structure and reduced resistance to wind and waves. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a honeycomb-type ecological floating island device and its usage method, aiming to improve the problems of lack of three-dimensional ecology, low sunlight utilization rate, weak purification capacity caused by the existing rectangular flat structure of floating islands, as well as poor adaptability and insufficient stability caused by fixed size.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a honeycomb-type ecological floating island device, including a planting box, wherein a floating block is provided inside the planting box, and both the planting box and the floating block are hexagonal structures;

[0007] T-shaped inserts are fixedly installed on three adjacent outer walls of the planting box, and slots adapted to the T-shaped inserts are opened on the other three adjacent outer walls of the planting box. Different planting boxes are assembled through inserts and slots.

[0008] Planting boxes (1) of different heights are configured according to the growth height requirements of aquatic plants. Planting boxes (1) of different heights are arranged in an alternating manner to form a three-dimensional staggered floating island structure to reduce dense shading of plants.

[0009] Preferably, the bottom of the planting box is provided with a bottom hole, and the position of the planting hole corresponding to the floating block is provided with a bottom hole; the bottom hole design facilitates the roots of aquatic plants to penetrate and extend into the water body, while ensuring root aeration and drainage, avoiding water accumulation and root rot, and promoting plant growth.

[0010] Preferably, the planting hole is frustum-shaped, with the larger circular opening facing upwards and the smaller circular opening facing downwards and connecting to the bottom hole; the frustum-shaped planting hole has a large upper opening for easy planting, and a small lower opening to stabilize the plant, and it accurately connects to the bottom hole, guiding the roots to extend smoothly and improving the planting survival rate.

[0011] Preferably, the bottom surface of the planting box is provided with a counterweight assembly, which includes a fixing block, a hanging rope, and a counterweight. The fixing block is fixedly connected to the lower end surface of the planting box, the hanging rope is tied in the opening of the fixing block, and the counterweight is fixedly connected to the lowest end of the hanging rope. The counterweight assembly can balance the buoyancy of the floating island, which is especially suitable for scenarios with a small number of pieces, effectively preventing the floating island from tilting or drifting due to wind and waves, and ensuring overall force balance.

[0012] Preferably, it also includes a standard section, on which T-shaped inserts are fixedly installed on three adjacent outer walls, and on which slots adapted to the T-shaped inserts are opened on the other three adjacent outer walls; the bottom end of the standard section cooperates with the top end of the planting box, so as to change the height of the planting box; the standard section can be flexibly added or removed, so as to realize the height of the planting box as needed, adapt to the growth height of different aquatic plants, and at the same time be compatible with modular splicing, expanding the application range of the floating island.

[0013] Preferably, the bottom end of the standard section is fixedly provided with an installation protrusion, and the top end of the standard section is provided with an installation groove that matches the installation protrusion. The top end of the planting box is also provided with an installation groove. The standard section is spliced ​​with the installation groove of the planting box through the installation protrusion, and the standard section is spliced ​​with the installation groove of other standard sections through the installation protrusion. The design of the matching of the installation protrusion and the groove ensures that the standard section and the planting box, as well as the standard sections themselves, are precisely and coaxially spliced, making assembly and disassembly convenient and improving splicing efficiency.

[0014] Preferably, the mounting protrusion has a through hole, and the planting box and other standard sections have fixing grooves at the corresponding positions of the through holes. The fixing grooves are connected to the mounting grooves, and fixing components are provided in the mounting grooves. The corresponding design of the through holes and fixing grooves provides force-bearing points for the fixing components, making the splice connection more secure and preventing loosening during use.

[0015] Preferably, the fixing component includes a limiting rod, one end of which is fixedly connected to a pull plate, and the other end of which is inserted into a fixing groove and passes through a through hole. A spring is sleeved on the outside of the limiting rod, one end of which is fixedly connected to the pull plate, and the other end of which is fixedly connected to the inner wall of the planting box or standard section. The spring drives the limiting rod to achieve quick fixing and unlocking, which is simple and labor-saving to operate, and has strong connection stability, ensuring the long-term reliability of the floating island structure.

[0016] Preferably, a protective sleeve is provided on the outer side of the spring, and the protective sleeve is fixedly connected to the inner wall of the planting box or standard section; the protective sleeve can isolate water corrosion and debris entanglement, protect the spring from damage, extend the service life of the fixing component, and reduce maintenance costs.

[0017] A method for using a honeycomb-type ecological floating island device includes the following steps:

[0018] S1: Survey the target water area to determine the treatment area, water depth, wind and wave intensity, and the required growth height of aquatic plants, and determine the number of planting boxes and standard sections to be used accordingly;

[0019] S2: Place the floats one by one into the bottom of the planting box, ensuring that the side surfaces of the floats are in close contact with the inner wall of the planting box, and ensuring that the frustum-shaped planting holes on the floats are precisely aligned with the bottom holes at the bottom of the planting box, thus preparing for subsequent plant planting.

[0020] S3: Using the pre-installed floating block planting box as the basic unit, keep the mounting groove at its top facing upwards and unobstructed; pull the pull plate on the side wall of the planting box. At this time, the spring is stretched, and the pull plate drives the limit rod to move inward along the fixing groove, releasing the limit rod's restriction and exposing the complete opening of the mounting groove; align the mounting protrusion at the bottom of the standard section with the mounting groove at the top of the planting box, and align the through hole with one side of the fixing component, and slowly insert the standard section vertically until the bottom of the mounting protrusion is completely in contact with the bottom of the mounting groove, ensuring that the standard section and the planting box are coaxially aligned; release the pull plate, and the spring returns to its original position under the action of elastic potential energy, pushing the limit rod through the through hole on the mounting protrusion, and the other end of the limit rod is inserted into the fixing groove of the planting box, completing the firm fixation of the standard section and the planting box;

[0021] S4: If it is necessary to further increase the total height of the planting box, the standard section that has been installed can be used as the basic unit, and the operation logic of step S can be repeated.

[0022] S5: Place all the planting box units that have completed the standard section splicing into the preset splicing position, select a planting box, align the T-shaped inserts on its three adjacent outer walls with the slots of the adjacent planting box, and slowly insert them vertically until the inserts are completely engaged in the slots to achieve a tight splicing of the two planting boxes.

[0023] S6: Repeat step S to assemble all the planting boxes in sequence, and finally form a three-dimensional, staggered, seamless honeycomb-like overall floating island structure;

[0024] S7: Count the total number of planting boxes to be assembled. If the number is small, the overall buoyancy distribution is concentrated and it is easily affected by wind and waves, causing it to tilt or drift. In this case, a heavy component needs to be installed. If the number is sufficient, a heavy component does not need to be installed.

[0025] S8: If the number of planting boxes is small, thread one end of the hanging rope through the opening of the fixing block on the bottom of the composite planting box and tie it tightly to ensure that the hanging rope is firmly connected to the fixing block. Fix the counterweight block to the other end of the hanging rope. It can be fixed by binding or buckle to ensure that the counterweight block is stably connected to the hanging rope and will not fall off due to water flow impact. Complete the assembly of the counterweight components of all composite planting boxes to ensure that each planting box has a set of counterweight components for each of the four fixing blocks to ensure balanced force.

[0026] S9: Insert the intended plant into each planting hole, so that the roots of the plant pass through the bottom hole of the planting box and extend to the outside of the planting box; transport the assembled honeycomb floating island to the target water area and let the floating island float naturally.

[0027] The present invention has the following beneficial effects:

[0028] 1. This invention, by configuring planting boxes of different heights and adopting a staggered arrangement design, breaks through the limitations of the single horizontal planting surface of existing floating islands, forming an orderly three-dimensional staggered structure. This layout can precisely adapt to the growth needs of aquatic plants of different heights, allowing tall and short plants to occupy suitable vertical space, avoiding light shading caused by dense mixing, and significantly improving the utilization rate of sunlight and water space. At the same time, the orderly three-dimensional structure can construct a stable three-dimensional ecological niche layer, forming gradient differences in underwater light, root distribution, and water flow environment, providing suitable habitat and foraging space for aquatic organisms at different water layers, improving the integrity and stability of the artificial ecosystem, thereby promoting the healthy growth of various plants and enhancing the floating island's ability to degrade pollutants such as COD, nitrogen, and phosphorus in the water.

[0029] 2. This invention allows for flexible adjustment of the overall size and layout of the floating island through the detachable splicing of standard sections and the modular assembly of the planting box, making it suitable for irregular waters. The disassembled planting box and standard section are compact in size, occupying little space during transportation and being easy to handle, thus reducing transportation costs. In addition, with optional counterweight components, the buoyancy of the floating island can be further balanced, its resistance to wind and waves can be enhanced, and the floating island can be prevented from tilting or drifting in the water, ensuring the long-term stable operation of the floating island.

[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] Reference Figures 1-4One embodiment of the present invention provides a honeycomb-type ecological floating island device, including a planting box 1, a floating block 2 inside the planting box 1, and both the planting box 1 and the floating block 2 are hexagonal structures; T-shaped inserts 11 are fixedly installed on three adjacent outer walls of the planting box 1, and slots 12 adapted to the T-shaped inserts 11 are opened on the other three adjacent outer walls of the planting box 1; different planting boxes 1 are assembled through inserts 11 and slots 12; planting boxes 1 of different heights are configured according to the growth height requirements of the aquatic plants; planting boxes 1 of different heights are arranged in an alternating manner to form a three-dimensional staggered floating island structure to reduce dense shading by plants.

[0047] The bottom of the planting box 1 has a bottom hole 13, and the bottom hole 13 is also provided at the position of the planting hole 21 corresponding to the floating block 2. The planting hole 21 is frustum-shaped, with the large round opening of the planting hole 21 facing upward and the small round opening facing downward and connecting to the bottom hole 13. A counterweight assembly 3 is provided on the bottom surface of the planting box 1. The counterweight assembly 3 includes a fixing block 31, a hanging rope 32 and a counterweight block 33. The fixing block 31 is fixedly connected to the lower end face of the planting box 1, the hanging rope 32 is tied in the opening of the fixing block 31, and the counterweight block 33 is fixedly connected to the bottom end of the hanging rope 32.

[0048] Specific implementation method: Survey the target water area to determine the treatment area, water depth, wave intensity, and required aquatic plant growth height. Based on this, determine the number of planting boxes 1 of three different heights (low, medium, and high). Place the float 2 into the bottom of each planting box 1 one by one, ensuring that the side surface of the float 2 is in close contact with the inner wall of the planting box 1. Ensure that the frustum-shaped planting hole 21 on the float 2 is precisely aligned with the bottom hole 13 at the bottom of the planting box 1, preparing for subsequent planting.

[0049] Place all planting boxes 1 in the preset splicing positions. Select one planting box 1 and align the T-shaped inserts 11 on its three adjacent outer walls with the slots 12 of the adjacent planting box 1. Slowly insert them vertically until the inserts 11 are fully engaged, achieving a tight splicing of the two planting boxes 1. Splice all planting boxes 1 in sequence in this manner, ensuring that planting boxes 1 of each height are surrounded by planting boxes 1 of different heights, ultimately forming a three-dimensional, staggered, seamless honeycomb-like integrated floating island structure.

[0050] Count the total number of planting boxes 1 in the final assembly. If the number is small, the overall buoyancy distribution will be concentrated, making it easy to tilt or drift due to wind and waves. In this case, it is necessary to install the weight component 3: pass one end of the suspension rope 32 through the opening of the fixing block 31 on the bottom of the planting box 1 and tie it tightly. Fix the other end to the counterweight block 33 by binding or buckling. Each of the four fixing blocks 31 of each planting box 1 is equipped with a set of counterweight components 3 to ensure balanced force. If the number of planting boxes 1 is sufficient, the buoyancy is balanced and the stability meets the requirements, then it is not necessary to install the weight component 3.

[0051] Insert the intended aquatic plant into each planting hole 21, so that the plant roots extend outward through the bottom hole 13 of the planting box 1; use hoisting equipment to slowly lift the assembled honeycomb floating island to the target water area, and place it steadily into the water to allow the floating island to float naturally, thus completing the deployment.

[0052] Post-maintenance requires regular inspections of the floating island, with a focus on checking for loose T-shaped inserts 11 and slots 12 at the joints of planting boxes 1. If any loosening is found, re-secure them immediately. Simultaneously, check the position of the float 2 to ensure that the planting hole 21 and bottom hole 13 are always precisely aligned. Regularly clean debris and algae around the planting hole 21 and bottom hole 13 to prevent blockages that could affect plant root respiration. Replant missing seedlings and thin out overly dense plants as needed, maintaining the ecological purification effect of the floating island. If the aquatic environment changes, the stability can be optimized by adjusting the number of planting boxes 1 to ensure the floating island continues to function effectively.

[0053] Example 2

[0054] Reference Figures 5-12 It also includes a standard section 4, on which T-shaped inserts 11 are fixedly installed on three adjacent outer walls, and slots 12 adapted to the T-shaped inserts 11 are opened on the other three adjacent outer walls of the standard section 4; the bottom end of the standard section 4 matches the top end of the planting box 1, so that the height of the planting box 1 can be changed.

[0055] The bottom of the standard section 4 is fixedly provided with an installation protrusion 42, and the top of the standard section 4 is provided with an installation groove 41 that matches the installation protrusion 42. The top of the planting box 1 is provided with an installation groove 41. The standard section 4 is spliced ​​with the installation groove 41 of the planting box 1 through the installation protrusion 42. The standard section 4 is spliced ​​with the installation groove 41 of other standard sections 4 through the installation protrusion 42.

[0056] The mounting protrusion 42 has a through hole 421. The planting box 1 and other standard sections 4 have fixing grooves at the positions corresponding to the through hole 421. The fixing grooves are connected to the mounting grooves 41, and fixing components 5 are provided in the mounting grooves.

[0057] The fixing component 5 includes a limiting rod 51, one end of which is fixedly connected to a pull plate 52, and the other end of which is inserted into a fixing groove and passes through a through hole 421. A spring 53 is sleeved on the outside of the limiting rod 51, one end of which is fixedly connected to the pull plate 52, and the other end of which is fixedly connected to the inner wall of the planting box 1 or the standard section 4. A protective sleeve 54 is sleeved on the outside of the spring 53, and the protective sleeve 54 is fixedly connected to the inner wall of the planting box 1 or the standard section 4.

[0058] Based on the first scheme, this scheme adds a standard section 4. The core difference lies in the height adjustment method of the planting box 1.

[0059] The specific differences are as follows: Planting box 1 has a uniform base height and needs to be expanded with standard section 4. During operation, with the planting box 1 after the pre-installed float 2 as the base unit, keep the top mounting groove 41 facing upwards without obstruction, pull the pull plate 52 on the side wall of planting box 1, the spring 53 is stretched and drives the limit rod 51 to move inward, exposing the complete opening of the mounting groove 41; align the mounting protrusion 42 at the bottom of the standard section 4 with the mounting groove 41 at the top of planting box 1, and align the through hole 421 on the mounting protrusion 42 with one side of the fixing component 5, slowly insert it vertically until the bottom of the mounting protrusion 42 is completely in contact with the bottom of the mounting groove 41, after releasing the pull plate 52, the spring 53 returns to its original position and pushes the limit rod 51 through the through hole 421 and into the fixing groove of planting box 1, thus completing the firm fixing of standard section 4 and planting box 1.

[0060] If the height needs to be further increased, the above splicing operation of standard section 4 can be repeated using the already installed standard section 4 as the base unit. The total height of the planting box 1 can be flexibly adjusted by increasing or decreasing the number of standard sections 4.
