Description

Technical Field

[0001] The present invention relates to the technical field of wetland ecological restoration, and in particular to a multifunctional combined module for a floating wetland in a stagnant water body. Background Art

[0002] Ecological restoration of stagnant water bodies is of great significance to improving water environment quality. As an effective ecological restoration method, floating wetlands have been widely used.

[0003] However, existing floating wetland modules present some practical problems. For example, after a period of growth, some plants' roots may grow too long, easily encroaching on the living space of other neighboring plants, causing root rot. Regular root pruning is necessary, but after assembly, it's difficult to track the growth of plant roots, making it impossible to perform root pruning. Furthermore, large floating wetland modules can be difficult to prune plants in the center of the module, requiring workers to stand on the module, which many modules cannot support, making plant pruning extremely inconvenient.

[0004] Moreover, the environment inside the module is not conducive to the breathing and growth of plant roots, which can easily cause plant root rot, affect plant survival and the purification effect of the wetland, and reduce the stability and durability of the entire floating wetland system. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a multifunctional combined module for a floating wetland for stagnant water bodies, which is convenient for pruning the roots and surfaces of plants.

[0028] The specific embodiments of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all inventions and creations utilizing the concepts of the present invention are protected.

[0029] like Figure 1-4As shown, a multifunctional modular module for floating wetlands in stagnant water bodies includes several modular units, which are assembled together to form a modular module. In other embodiments of the present invention, the number and arrangement of modular units are set according to actual needs, and the planting matrix, denitrification enhancer slow-release tank or phosphorus removal enhancer slow-release tank are selected according to requirements. The denitrification enhancer slow-release tank and the phosphorus removal enhancer slow-release tank are generally loaded near the center of the modular module. The planting matrix includes sulfur particles, iron sulfide particles, iron hydroxide particles and coconut shell activated carbon; the denitrification enhancer slow-release tank is loaded with a combination of one or more of ethanol, methanol and acetic acid; the phosphorus removal enhancer slow-release tank is loaded with a combination of one or more of ferric chloride, ferrous sulfate, ferrous sulfate, ferrous chloride, aluminum sulfate, sodium aluminate and calcium hydroxide.

[0030] The module unit includes a floating inner basket 1 and a sinking outer basket 2. The inner basket 1 is made of buoyancy material, and the bottom and side walls of the inner basket 1 are mesh-shaped. The inner basket 1 uses buoyancy materials commonly used in floating wetlands, such as foam plastics, high-molecular composite polyester fiber materials, polyurethane foam or fiber composite materials; the outer basket 2 is made of metal material. When the module unit is placed in a water body, the inner basket 1 floats upward under the action of buoyancy, and there is a gap between the basket edge of the inner basket 1 and the basket edge of the outer basket 2. Water from the water body enters the inner basket 1 through the gap, and the water body comes into contact with the planting matrix in the inner basket 1.

[0031] The outer basket 2 and the inner basket 1 are connected by a vertical connecting rod 14. The side wall of the outer basket 2 slides in contact with the side wall of the inner basket 1. The bottom of the outer basket 2 is provided with an opening 3. A horizontally movable opening and closing plate 4 is provided at the opening 3. When the plate 4 is open, a sharp edge 5 is provided on the side of the plate 4 close to the opening 3.

[0032] The basket edge of the outer basket 2 is provided with a hook 6 hole that cooperates with the hook 6, and two adjacent module units are connected by the hook 6; the number of module units is selected according to the design size of the modular module, and the module units are connected and combined using the hook 6.

[0033] The inner basket 1 is provided with a planting matrix, a denitrification enhancer slow-release tank or a phosphorus removal enhancer slow-release tank; the slow-release tank adopts the slow-release structure disclosed in the prior art application number CN202220370868.0, so no further details are given.

[0034] The output end of the denitrification enhancer slow-release tank or the phosphorus removal enhancer slow-release tank is connected with a mesh pipe, the mesh pipe is provided with a plurality of output pipes, and one end of the output pipe away from the mesh pipe is inserted into the planting matrix.

[0035] The bottom surface of the clamping plate 4 is provided with a linkage latch hole 7, which is connected to a linkage rod 8. The linkage rod 8 is provided with several latching rods 9 that mate with the linkage latch holes 7. These latching rods 9 are simultaneously connected to the clamping plates 4 of the modular units located in the same row. In practice, the latching rods 9 are bolts, and the linkage rods 8 are provided with screw holes that mate with the bolts. By disassembling and assembling the latching rods 9, the clamping plates 4 of the modular units in the same row of the modular module can be flexibly controlled to open and close. In actual use, modular units such as those equipped with slow-release tanks for denitrification enhancers or dephosphorization enhancers can keep the latching plates 4 in the open position at all times.

[0036] The linkage clamping hole 7 is a T-slot, and the T-slot is perpendicular to the length direction of the linkage rod 8 .

[0037] The device also includes a facilitating mechanism for opening and closing the clamping plate 4. This mechanism includes a mating rod 10 connected to the bottom of the outer basket 2 of the modular unit in the same row. A-shaped facilitating clamps 11 are provided at both ends of the mating rod 10, one end of which is connected to the mating rod 10 and the linkage rod. In practice, the connection between the mating rod 10 and the bottom of the outer basket 2 is similar to the connection between the linkage rod and the clamping plate 4.

[0038] A hydraulic rod 12 is horizontally provided at one end of the A-type power-assisting clamp 11 away from the linkage rod, and both ends of the hydraulic rod 12 are connected to the A-type power-assisting clamp 11 through hinges.

[0039] An opening 13 is provided on the edge of the inner basket 1, and the opening 13 is slidably fitted with a connecting rod 14. The bottom end of the connecting rod 14 is fixedly connected to the edge of the outer basket 2, and a limit block 15 is provided at the top end of the connecting rod 14; the diameter of the limit block 15 is larger than the diameter of the opening 13.

[0040] The limiting block 15 is in the shape of a double-ended cone, the maximum diameter of which is larger than the diameter of the opening 13 ; a plurality of symmetrically arranged hook holes 16 are further provided on the edge of the inner basket 1 .

[0041] When plant roots need to be trimmed, the connecting rod 8 and the matching rod 10 are connected underwater to the connecting rod holes 7 of the inner plate and outer basket 2, respectively. Two workers are assigned to simultaneously push the connecting rod 8 on both sides of the modular module, moving the clamping plate 4. The slits on the clamping plate 4 cut off the plant roots that extend beyond the bottom of the outer basket 2. To save manpower, the two workers can simultaneously use a power clamp to help bring the connecting rod and the matching rod 10 closer together, allowing the clamping plate 4 to cut off the excessively long plant roots. To further save labor, after the power clamp is connected to the connecting rod 8 and the matching rod 10, a hydraulic rod 12 can be used for power assistance.

[0042] When it is necessary to trim or replace the plants in the center of the modular module, the worker uses a crane tool to lift the inner basket 1. Under the weight of the outer basket 2 and the action of other connected modules, the inner basket 1 can be lifted away from the outer basket 2 by the crane, so that the center of the modular module can be lifted to the edge of the module, making it easier for workers to trim the plants.
