Description

Technical Field

[0001] This utility model relates to the field of floating wetland technology, specifically to a composite floating wetland that combines floating island planting and submerged plant planting. Background Technology

[0002] Floating wetlands are a novel water purification and aquatic ecosystem restoration technology. They remove pollutants and restore the ecosystem by constructing artificial wetland-like structures in water bodies. Planting emergent and submerged plants helps to build a more complex and stable ecosystem, improving the wetland's adaptability and resistance to environmental changes. Submerged plants can also make full use of nitrogen and phosphorus in the water. Existing technologies lack composite floating wetlands that are stable in performance and can simultaneously meet the needs of both floating island planting and submerged plant planting. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing floating wetlands and to provide a composite floating wetland that combines floating island planting with submerged plant planting.

[0004] To achieve the above and other objectives, this utility model is implemented through the following technical solution: This utility model provides a composite floating wetland of floating island planting and submerged plant planting, the composite floating wetland comprising: a frame, the frame comprising multiple supports connected together; a submerged blanket fixed within the frame; floating islands fixed within the frame and disposed on the submerged blanket, the floating islands comprising a first polyester fiber layer, a first float, a plant fiber layer, and a second polyester fiber layer stacked sequentially, the first polyester fiber layer, the plant fiber layer, and the second polyester fiber layer having openings filled with foamed polyurethane; and multiple connecting nets connected to the bottom of the frame and enclosing the frame and the submerged blanket to form a receiving cavity.

[0005] This invention provides a composite floating wetland combining floating island planting and submerged plant planting. Compared with the prior art, this invention has the following advantages: the composite floating wetland can simultaneously meet the growth needs of submerged and emergent plants. Submerged and emergent plants each have different purification mechanisms and ecological functions, and they can work synergistically to more effectively remove nutrients such as nitrogen and phosphorus from the water. The floating islands are made of foamed polyurethane material, which helps to improve the overall buoyancy of the floating wetland. Attached Figure Description

[0012] Please see Figures 1 to 6 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0013] This invention provides a composite floating wetland that can simultaneously cultivate submerged plants 100 and emergent plants 200. The composite floating wetland includes a frame 1, which may include multiple connected supports 11, for example, at least 8-12 supports 11, which allow the frame 1 to form a cube. The frame 1 may be made of plastic.

[0014] like Figure 1 and Figure 4 As shown, the composite floating wetland includes a submerged blanket 2, which can be located within the frame 1. The submerged blanket 2 may include a submerged blanket body 21 and a first fixing net 22 located around the submerged blanket body 21. The submerged blanket body 21 may be made of plant fiber material. The submerged blanket 2 can be used to plant submerged plants 100. The submerged blanket 2 can be fixed to the frame 1 by the first fixing net 22. The plant fiber may be straw fiber or coconut fiber.

[0015] like Figure 1 and Figure 5As shown, the composite floating wetland includes floating islands 3, which can be located within the frame 1 and disposed on the submerged blanket 2. Each floating island 3 may include a first polyester fiber layer 31, which is located on the submerged blanket 2 and has openings. The floating island 3 also includes a first float 32. In some embodiments, the first float 32 may include 2-3 layers of first floats. The floating island 3 includes a plant fiber layer 33, which is located on the first float 32 and has openings. The floating island 3 may also include a second polyester fiber layer 34, which has openings filled with polyurethane foam 35. The polyurethane foam 35 connects the layers of the floating island 3, stabilizing it and enhancing its buoyancy. The thickness of the first float 32 can be 15-30 cm.

[0016] like Figure 5 As shown, specifically, the floating island 3 also includes a second fixing net 36 covering the first polyester fiber layer 31, the first float 32, the plant fiber layer 33 and the second polyester fiber layer 34. The second fixing net 36 can also be fixed on the frame 1. Both the first fixing net 22 and the second fixing net 36 can be made of PP material.

[0017] like Figure 4 As shown, in some embodiments, the composite floating wetland includes a connecting net 4, which can be fixed to the bottom of the frame 1. Specifically, there may be multiple connecting nets 4. Underwater, the connecting nets 4 can enhance the floating island 3's resistance to water flow impact and protect the submerged plants 100 while ensuring a certain amount of sunlight penetration, and to some extent, providing space for the growth of microorganisms. The connecting net 4 can be a plastic mesh or a galvanized mesh. The multiple connecting nets 4 are connected to the bottom of the frame 1 and together with the frame 1 and the submerged blanket 2 form a receiving cavity, which can provide space for the submerged plants to grow.

[0018] like Figure 2 and Figure 3 As shown, the composite floating wetland includes a connecting rod 5, which can be a spiral connecting rod 5. The connecting rod 5 can fix two adjacent connecting nets 4 onto the bracket 11 of the frame 1, facilitating assembly and disassembly. Furthermore, the top of the connecting rod 5 can extend beyond the top of the connecting net 4, which facilitates the connection of the connecting rod 5 with the submerged blanket 2 and the floating island 3, enhancing the stability of the connecting net 4.

[0019] like Figure 6As shown, to enhance the buoyancy of the composite floating wetland and simultaneously support the growth of emergent plants 200 and submerged plants 100, the composite floating wetland includes a second float 6. The second float 6 can be made of foam material and can cover the support 11, for example, covering the support 11 where the floating island 3 is located at the top of the frame 1. The first float 32 and the second float 6 can be made of materials such as PE and PVC.

[0020] When this utility model is used, one or more layers of planting medium can be laid on the floating island 3 to provide nutrients for the growth of emergent plants 200, while submerged plants 100 can be pre-planted into the submerged blanket body 21.

[0021] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
