Description

Technical Field

[0001] This utility model relates to the technical field of aquatic plant breeding modules, and in particular to an aquatic plant breeding module that can release nutrients slowly. Background Technology

[0002] In the fields of aquatic ecological restoration, landscape horticulture and sustainable aquaculture, the construction of floating bed systems using aquatic plants is a widely used technical means. Aquatic plants absorb excess nutrients such as nitrogen and phosphorus in the water through their roots, which can effectively purify water quality, inhibit algae growth, improve water transparency, and provide habitats for aquatic organisms, thereby achieving a virtuous cycle of the aquatic ecosystem. Traditional floating plant beds face some shortcomings in practical application. Plants are prone to insufficient nutrient supply in the early stages of growth or in nutrient-poor water conditions. Conventional soil or substrates are prone to loss of inherent nutrients in long-term immersion environments, making it difficult to sustain plant growth. If fertilizer is applied directly to the water, not only is the nutrient utilization rate low and the economic cost high, but it will also lead to secondary pollution of the water body, which runs counter to the original intention of ecological restoration. This contradiction seriously restricts the effectiveness and long-term stability of aquatic plants in water purification. To address the aforementioned issues, the development of a floating bed module capable of autonomously and sustainably supplying nutrients has become an urgent need in the industry. By embedding slow-release nutrient technology into the cultivation substrate of the floating bed module, "precise nutrient supply" to plant roots can be achieved. Nutrients are released slowly at a controllable rate throughout the plant's growth cycle, which not only meets the nutritional needs of plants at different growth stages but also greatly avoids the ineffective loss of nutrients to water bodies, fundamentally solving the problem of nutrient supply versus pollution.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A slow-release nutrient aquatic plant propagation module, such as Figures 1 to 4 As shown, the module includes a main body, and two main bodies are connected by a connector. The connector includes a clamping plate 5, a side plate 12, and a sliding plate 13. The two side plates 12 are respectively fixed to both ends of the sliding plate 13 by screws. The two clamping plates 5 and the sliding plate 13 are slidably connected. The two clamping plates 5 are fixed by a fixing mechanism. The inner side of the clamping plate 5 and the main body of the module are positioned by a positioning component. The module body is used to propagate aquatic plants. The module body can be used alone or multiple module bodies can be connected with connectors for large-scale use, which enhances the overall stability and resists the erosion of wind and waves. When it is necessary to connect two module bodies, the two module bodies are first initially positioned from the side using positioning components. The purpose of positioning is to ensure that the two module bodies are aligned from the side. In this embodiment, the cross-section of the bottom of the module body is preferably square, which ensures that the module body does not need to distinguish between the long side and the short side when performing lateral positioning. After positioning, the two clamping plates 5 are slid relative to each other along the slide plate 13. The side plate 12 plays a limiting role for the clamping plates 5, preventing the clamping plates 5 and the slide plate 13 from separating from each other. As the relative movement between the two clamping plates 5 progresses, when the inner side of the clamping plate 5 and the inner side of the module body come into contact with each other, the two clamping plates 5 limit the two module bodies by clamping. After limiting, the two clamping plates 5 are fixed together by a fixing mechanism, thus completing the connection between the two module bodies.

[0020] The main body of the module includes a frame 1, a top plate 2 and an inner frame 3. The bottom of the inner frame 3 and the bottom inner wall of the frame 1 are fixedly connected by screws. The top plate 2 is fixed between the inner wall of the frame 1 and the outer wall of the inner frame 3 by screws. A floating block 14 is fixed to the outer side of the inner frame 3 by screws. A gap is formed between the inner frame 3 and the frame 1 to install and accommodate the float 14. The float 14 improves the buoyancy of the entire module body, allowing it to float on the water surface. The float 14 can be made of closed-cell foam material, such as EPE pearl cotton or EVA ethylene-vinyl acetate copolymer, which has the characteristics of being lightweight, having low water absorption, being corrosion resistant, and providing durable buoyancy. The frame 1, top plate 2, and float 14 are preferably made of biodegradable materials such as straw fiber or PLA polylactic acid, which have good environmental protection properties.

[0021] The bottom of the frame 1 is provided with a hole 15, and the space between the bottom of the frame 1 and the interior of the inner frame 3 is filled with a cultivation section 6. By incorporating a structure that allows aquatic plant roots to pass through and absorb nutrients from the water, while facilitating water exchange, the cultivation section 6 is used to fix aquatic plant seedlings or rhizomes and provide initial support. The cultivation section 6 has a high porosity, which is beneficial for root development. The cultivation section 6 includes a substrate layer and a slow-release nutrient layer. The substrate layer can be composed of one or more of the following: pumice, expanded clay, coconut coir, soil, etc. The slow-release nutrient layer is wrapped by the plant growth substrate layer and can be a solid unit with a certain shape, such as spheres or blocks. The slow-release nutrient layer is made by mixing and pressing or wrapping water-soluble fertilizers such as nitrogen, phosphorus, potassium and trace elements with a slow-release carrier material. The slow-release carrier material is a biodegradable polymer material such as starch-based plastic or PVA polyvinyl alcohol. Its degradation rate controls the nutrient release. When it comes into contact with water, the nutrients will be slowly released into the surrounding substrate and water through diffusion, dissolution or material degradation, providing long-term and stable nutrient supply for plants.

[0022] The positioning component includes a positioning hole 4 and a positioning post 11. The positioning post 11 is welded to the inner wall of the clamping plate 5. The positioning hole 4 is opened on the side of the frame 1, and the positioning post 11 and the positioning hole 4 are inserted together. When positioning is required between two module bodies, the sides of two adjacent frames 1 are fitted together, and two clamping plates 5 are placed between the two fitted sides of the two frames 1. The two clamping plates 5 are moved relative to each other, so that the positioning pins 11 on the two clamping plates 5 are inserted into the positioning holes 4 on the corresponding sides of the frames 1. The edges of the frames 1 protrude from the top plate 2. After the positioning pins 11 are inserted into the inner wall of the positioning holes 4, the two module bodies are limited in the longitudinal direction.

[0023] The fixing mechanism includes a docking plate 9 and a locking hole 10. The docking plate 9 is welded to the top outer wall of the clamping plate 5. The locking hole 10 is opened on the surface of the docking plate 9. The fixing mechanism also includes a bolt 7 and a nut 8. The nut 8 and the bolt 7 are threadedly connected, and the locking hole 10 and the bolt 7 are mutually compatible. When fixing the two clamping plates 5, the bolt 7 is passed through the two locking holes 10 in sequence, and the threaded connection between the nut 8 and the bolt 7 is locked to complete the fixed connection between the two clamping plates 5.

[0024] Working principle: The main body of the module fixes aquatic plants and provides initial support through the cultivation part 6 filled inside. The drainage holes 15 at the bottom of the frame 1 facilitate root extension and water exchange. The float 14 provides buoyancy to make the main body of the module float. When connecting, the sides of the two main bodies of the module are aligned, and the positioning pins 11 on the inside of the clamping plate 5 are inserted into the positioning holes 4 on the side of the frame 1 to achieve lateral positioning. Then, the clamping plate 5 is slid relative to the sliding plate 13 to clamp the main body of the module. Finally, the bolts 7 and nuts 8 are passed through the locking holes 10 of the docking plate 9 to lock and fix the module, so as to achieve a stable connection between the main bodies of the module and enhance the overall wind and wave resistance.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
