Description

Technical Field

[0001] This utility model belongs to the field of wetland restoration technology, specifically relating to a modular floating island for water purification in wetland restoration. Background Technology

[0002] Wetlands possess unique structural and functional properties for removing nutrients and pollutants from water, playing a vital role in maintaining watershed ecological balance and aquatic environment stability. Ecological restoration, guided by ecological principles and based on bioremediation, is a method for remediating wetland water pollution. Successful implementation of ecological restoration requires the participation of multiple disciplines, including ecology, physics, chemistry, botany, microbiology, molecular biology, culinary science, and environmental engineering. The restoration and maintenance of damaged ecosystems involve various ecological theories such as ecological stability, ecological plasticity, and homeostasis.

[0003] Existing floating islands for water purification in wetland restoration often use fixed foam boards assembled on-site with supports. However, due to the varying sizes of wetlands, workers need to assemble the floating islands on-site according to the wetland's area, resulting in time-consuming construction of the water purification floating islands.

[0004] Based on this, a modular wetland restoration water purification floating island was designed, which uses magnets to fix the floating modules. Summary of the Invention

[0005] This utility model addresses the shortcomings of existing technologies by providing a modular floating island for wetland restoration water purification. The specific technical solution is as follows:

[0006] A modular floating island for wetland restoration water purification includes a first floating module and a second floating module. At least one second floating module is provided. The first floating module includes a first foam board and a protective plastic edge for the outside of the first foam board. The second floating module includes a second foam board and a protective plastic edge for the outside of the second foam board. Magnets are fixed in holes on the four sides of the first and second foam boards. Limiting protrusions are integrally formed on two adjacent sides of the plastic edge. Limiting holes adapted to the limiting protrusions are opened on the other two adjacent sides of the plastic edge. When the limiting holes are opened, they also extend to the sides of the first foam board and the central hole. The S pole of the magnetic field of the magnets installed on opposite sides of the first foam board and the central hole points to the limiting protrusions.

[0007] The first floating module is equipped with an oxygenation mechanism for supplying oxygen to the water.

[0008] The second foam board has planting holes arranged in a matrix. The inner surface of the planting holes is bonded with absorbent cotton tubes, and the lower surface of the second foam board is bonded with an absorbent cotton layer for absorbing water, with the absorbent cotton tubes in contact with the absorbent cotton layer.

[0009] Preferably, the oxygenation mechanism includes an air pump fixed to the upper surface of a first foam board. A central hole is provided in the middle of the first foam board. The air outlet of the air pump passes through the central hole and is fitted with a sealed bearing. A main air guide pipe is installed inside the sealed bearing. A branch air guide pipe is installed at the lower end of the main air guide pipe. Air outlets are evenly spaced on the surface of the branch air guide pipe, and the air outlets are perpendicular to the rotation axis of the sealed bearing.

[0010] Preferably, the surface of the gas guide branch pipe is welded with stirring blades, and the stirring blades have a spiral structure.

[0011] Preferably, the air guide branch pipes installed at the lower end of the main air guide pipe are arranged in a ring array, and the air outlet is connected to the air outlet of the air pump through the air guide branch pipes and the main air guide pipe.

[0012] Preferably, the plastic edge protector has two limiting protrusions and two limiting holes on each side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A first floating module consisting of a first foam board, plastic edge protector, magnet, limiting protrusion, and limiting hole; and a second floating module consisting of a second foam board, plastic edge protector, planting hole, absorbent cotton tube, absorbent cotton layer, magnet, limiting protrusion, and limiting hole. Since both the first and second foam boards are equipped with plastic edge protectors, when the first and second floating modules are assembled, and when two second floating modules are assembled, the sides of the two plastic edge protectors are connected to each other. Simultaneously, a limiting protrusion integrally formed on the side surface of one plastic edge protector is inserted into a limiting hole on the side surface of the other plastic edge protector. Furthermore, the S pole of the magnetic field of the magnet installed opposite the center hole on the first foam board points towards the limiting protrusion, thus enabling the first and second floating modules, as well as the two second floating modules, to achieve this connection. Both floating modules are magnetically secured, improving the convenience and stability of modular assembly of the first and second floating modules. The planting holes in the second foam board allow for easy contact between the water-absorbing cotton tubes bonded within the holes and the water-absorbing cotton layer bonded to the lower surface of the second foam board. This facilitates the absorption of water from the water-absorbing cotton tubes and layer by the roots of the aquatic plants planted in the holes, increasing the vegetation cover of the wetland and promoting water purification. Increased vegetation cover also helps restore the biodiversity of the wetland. The oxygenation mechanism on the first floating module allows for oxygenation of the wetland water, preventing oxygen deficiency caused by excessive aquatic plants.

[0015] 2. An oxygenation mechanism consisting of an air pump, a sealed bearing, a main air supply pipe, branch air supply pipes, an air outlet, and stirring blades is used. The air pump outlet, fixed on the upper surface of the first foam board, is connected to the main air supply pipe via the sealed bearing. The branch air supply pipes, arranged in a ring array at the lower end of the main air supply pipe, and the air outlets mounted on the surface of the branch air supply pipes, allow the air pump to discharge air through the main air supply pipe and branch air supply pipes after the circuit is connected to the wetland. Since the air outlet is perpendicular to the rotation axis of the sealed bearing, the air outlet generates thrust when discharging air, causing the branch air supply pipes to rotate around the rotation axis of the sealed bearing. This disperses the air discharged from the air outlet into the water body of the wetland. The stirring blades welded to the surface of the branch air supply pipes agitate the water body when the branch air supply pipes rotate, increasing the water flow. Attached Figure Description

[0026] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1-9 This embodiment provides the following technical solution: a modular floating island for water quality purification in wetland restoration, including a first floating module 1 and a second floating module 2. At least one second floating module 2 is provided. The first floating module 1 includes a first foam board 11 and a plastic protective edge 22 for protection on the outside of the first foam board 11. The second floating module 2 includes a second foam board 21 and a plastic protective edge 22 for protection on the outside of the second foam board 21. Magnets 26 are fixed in holes on the four sides of the first foam board 11 and the second foam board 21. Limiting protrusions 27 are integrally formed on two adjacent sides of the plastic protective edge 22. Limiting holes 28 adapted to the limiting protrusions 27 are opened on the other two adjacent sides of the plastic protective edge 22. When the limiting holes 28 are opened, they also extend to the sides of the first foam board 11 and the center hole 12. The S pole of the magnetic field of the magnets 26 installed on opposite sides of the first foam board 11 and the center hole 12 points to the limiting protrusions 27.

[0028] The first floating module 1 is equipped with an oxygenation mechanism 3 for supplying oxygen to the water.

[0029] The second foam board 21 has planting holes 23 arranged in a matrix. The inner surface of the planting holes 23 is bonded with absorbent cotton tubes 24, and the lower surface of the second foam board 21 is bonded with absorbent cotton layers 25 for absorbing water, and the absorbent cotton tubes 24 are in contact with the absorbent cotton layers 25.

[0030] In this embodiment, a first floating module 1, composed of a first foam board 11, plastic edge protector 22, magnet 26, limiting protrusion 27, and limiting hole 28, and a second floating module 2, composed of a second foam board 21, plastic edge protector 22, planting hole 23, absorbent cotton tube 24, absorbent cotton layer 25, magnet 26, limiting protrusion 27, and limiting hole 28, are used. Since both the first foam board 11 and the second foam board 21 are provided with plastic edge protectors 22, when the first floating module 1 and the second floating module 2 are assembled, and when the two second floating modules 2 are assembled, the sides of the two plastic edge protectors 22 are connected to each other. Simultaneously, the limiting protrusion 27 integrally formed on the side surface of one plastic edge protector 22 is inserted into the limiting hole 28 opened on the side surface of the other plastic edge protector 22. At the same time, the S pole of the magnetic field of the magnet 26 installed opposite to the first foam board 11 and the center hole 12 points to the limiting protrusion 27, thus enabling the first floating module 21 to float. Module 1 and the second floating module 2, as well as the two second floating modules 2, are all magnetically fixed by magnets 26, thereby improving the convenience and stability of modular assembly of the first floating module 1 and the second floating module 2. The planting holes 23 opened in the second foam board 21 are in contact with the water-absorbing cotton tubes 24 bonded in the planting holes 23 and the water-absorbing cotton layer 25 bonded to the lower surface of the second foam board 21, so that the roots of the aquatic plants planted in the planting holes 23 can absorb the water in the water-absorbing cotton tubes 24 and the water-absorbing cotton layer 25. This facilitates the increase of vegetation coverage in the wetland by the aquatic plants planted in the planting holes 23, which is conducive to the purification of water by aquatic plants. The increased vegetation coverage is conducive to the restoration of the ecological diversity of the wetland. The oxygenation mechanism 3 set on the first floating module 1 facilitates the oxygenation of the wetland water through the oxygenation mechanism 3, so as to avoid the problem of water hypoxia caused by excessive aquatic plants.

[0031] Specifically, the oxygenation mechanism 3 includes an air pump 31 fixed on the upper surface of the first foam board 11. A central hole 12 is provided in the middle of the first foam board 11. The air outlet of the air pump 31 passes through the central hole 12 and is fitted with a sealed bearing 32. A main air guide pipe 33 is installed inside the sealed bearing 32. A branch air guide pipe 34 is installed at the lower end of the main air guide pipe 33. Air outlets 35 are evenly spaced on the surface of the branch air guide pipe 34 and are perpendicular to the rotation axis of the sealed bearing 32. A stirring blade 36 is welded to the surface of the branch air guide pipe 34. The stirring blade 36 has a spiral structure. The branch air guide pipes 34 installed at the lower end of the main air guide pipe 33 are arranged in a ring array. The air outlets 35 are connected to the air outlet of the air pump 31 through the branch air guide pipes 34 and the main air guide pipe 33.

[0032] In this embodiment, an oxygenation mechanism 3, consisting of an air pump 31, a sealed bearing 32, a main air supply pipe 33, branch air supply pipes 34, an air outlet 35, and a stirring blade 36, is used. The air outlet of the air pump 31, fixed to the upper surface of the first foam board 11, is connected to the main air supply pipe 33 via the sealed bearing 32. The branch air supply pipes 34, arranged in a ring array at the lower end of the main air supply pipe 33, and the air outlets 35 mounted on the surface of the branch air supply pipes 34, ensure that after the air pump 31 is connected to the wetland installation circuit, the air pump 31 outputs... The air is exhausted through the main air guide pipe 33 and the branch air guide pipe 34 via the air outlet 35. Since the air outlet 35 is perpendicular to the rotation axis of the sealing bearing 32, the air outlet 35 generates thrust when it exhausts air, causing the branch air guide pipe 34 to rotate around the rotation axis of the sealing bearing 32. This disperses the air exhausted from the air outlet 35 into the water body of the wetland. The stirring blades 36 welded to the surface of the branch air guide pipe 34 stir the water body when the branch air guide pipe 34 rotates, increasing the water flow.

[0033] Specifically, each side of the plastic edge protector 22 is provided with two limiting protrusions 27 and two limiting holes 28 to increase the stability when two adjacent plastic edge protectors 22 are connected.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
