Description

Technical Field

[0001] The utility model belongs to the technical field of ecological restoration, and in particular relates to a lake wetland restoration device. Background Art

[0002] Lake wetlands are formed by the swamping process of lake shores or shallow lakes, and also include the lake water itself. Lake wetlands belong to ecological transition zones and have unique structures and functions. Structurally, lake wetlands are composed of lakeside buffer zones, lakeside zones, and lake waters. The lakeside buffer zone is dominated by trees and shrubs, the lakeside zone is dominated by wetland plants and emergent plants, and the lake waters are dominated by submerged plants and floating plants. These plants, together with life factors such as animals and microorganisms living in them, and non-life factors such as sunlight, water, and soil, are in a dynamic open system, interconnected, mutually restricted, and play a series of functions. Lake wetlands have ecological values ​​such as flood control, sedimentation control, water quality improvement, and biodiversity, as well as economic values ​​such as climate regulation, water supply, aquaculture, and shipping.

[0003] At present, with the continuous development of the economy, lakes and wetlands are also facing environmental problems. The main environmental problems are the disappearance of a large number of lakes and wetlands and the increasingly serious environmental pollution. The commonly used method of lake wetland restoration is to plant aquatic plants in the wetlands, such as reeds and Vallisneria, which have a good absorption effect on nutrients and pollutants in the water. The plant-based water body restoration system is a low-energy treatment system with solar energy as the main energy source. However, the process of purifying water using this method is quite slow and is affected by the external weather.

[0004] The utility model patent with announcement number CN213265915U discloses a lake wetland restoration device, including a wetland and a water body therein, characterized in that: the water body is surrounded by protective embankments, a water pump is arranged on the wetland, the water pump is respectively connected to a pumping pipe assembly and a water supply pipe, the pumping pipe assembly is connected to the water body and suspended on the surface of the water body, the pumping pipe assembly includes a main pipe and a plurality of branch pipes arranged at equal intervals along the axial direction of the main pipe, the main pipe and the branch pipes are connected to each other, a plurality of pumping holes are opened on the main pipe and the branch pipes, a plurality of inflatable bags are also attached along the axial direction of the main pipe, an inflatable bag is also attached to the end of each branch pipe, an infiltration bed is arranged on the wetland, and the water supply pipe is connected to the infiltration bed. Although this technical solution uses an infiltration bed, a submersible pump, a pumping assembly, and a water delivery pipe, and correspondingly plants submerged plants in the water body to form a water circulation purification micro-ecosystem to repair the lake wetland, the above solution requires the lake water to be pumped to the infiltration bed by a submersible pump before the lake water can be purified, and the purified water is directly discharged into the water body and mixed with the unpurified water. When the submersible pump is pumping, it may pump up the purified water, resulting in the inability to pump up the unpurified water. Therefore, there is a problem that the lake water may not be completely purified. Utility Model Content

[0020] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] like Figure 1As shown, the embodiment of the utility model provides a lake wetland restoration device, which specifically includes a floating board 1 and a bottom plate 2 located below the floating board 1. The material of the floating board 1 is specifically selected from materials with relatively large buoyancy. Through the design of the floating board 1, the floating board 1 can float on the water surface, and the buoyancy of the lake water can vertically support the entire restoration device; the bottom plate 2 is designed to support the floating board 1 and the infiltration wall 3, improve the stability of the entire device, and is used to install the motor 401; a plurality of infiltration walls 3 parallel to each other are vertically arranged between the floating board 1 and the bottom plate 2, and the plurality of infiltration walls 3 are designed to be spaced apart from each other. In the specific design, the number of infiltration walls 3 is determined by the size of the lake. When the area of ​​the lake is relatively large, the number of infiltration walls is designed to be more, which can make the purification effect more stable; the height of the infiltration wall 3 should be able to extend through the entire water body depth during the specific design, so that a purification reaction wall can be established in the depth direction of the water body, and the adsorption purification function can be realized in the lake water, so as to achieve full and effective purification of the lake water; the top of each infiltration wall 3 is fixed to the bottom of the floating board 1 by screws, and the bottom is fixed to the top of the bottom plate 2 by screws;

[0022] A toggle mechanism 4 is provided on the side of the bottom plate 2. A submerged plant 5 is also planted on the top of the bottom plate 2. The submerged plant 5 can further increase the habitat of decomposers (microorganisms) in the water body 2, thereby absorbing and removing dissolved organic matter, algae, colloids and suspended matter in the water body.

[0023] like Figure 2As shown, the permeable wall 3 comprises an activated carbon layer 301, a zeolite layer 302 and an organic material layer 303 which are arranged adjacent to each other in sequence. The activated carbon layer 301, the zeolite layer 302 and the organic material layer 303 are fixedly connected. Through the design of the activated carbon layer 301, COD in the water body can be well removed, while the zeolite layer 302 can well remove ammonia nitrogen in the water body, and the organic material layer 303 can well remove COD, nitrogen and phosphorus elements in the water body. In the specific design, the organic material in the organic material layer 303 is fermented crop straw, sawdust or nut skin. The purpose of such a design is not only to turn waste into treasure, which is conducive to the recycling of materials, but also to obtain the effect of purifying water bodies. In the specific design, the permeable wall 3 can also be designed as a permeable wall containing only an organic material layer according to actual conditions. The design of a permeable wall containing only an organic material layer is suitable for situations where the pollutant content in the water body is not very high. COD, N, and P in the water body can be better removed through the action of microorganisms, and this design has the advantage of low cost. In the actual purification process, if the pollutant content in the water body is too high or the water body needs to be purified as soon as possible, the permeable wall 3 can be designed as a permeable wall containing an activated carbon layer 301, a zeolite layer 302, and an organic material layer 303 in this embodiment, so as to achieve a better water purification effect in a shorter time.

[0024] like Figure 3 As shown, the toggle mechanism 4 includes a motor 401, a connecting rod 402 and a plurality of toggle plates 403. The motor 401 is welded and installed on the side of the bottom plate 2. One end of the connecting rod 402 is fixedly connected to the output shaft of the motor 401. The plurality of toggle plates 403 are welded and arranged on the outer surface of the connecting rod 402 at intervals along the circumferential direction. The motor 401 is designed to drive the connecting rod 402 to rotate. The rotation of the connecting rod 402 drives the plurality of toggle plates 403 to rotate continuously. The continuously rotating toggle plates 403 drive the water flow and drive the entire device to move slowly in the water body.

[0025] The angle between the toggle plate 403 and the connecting rod 402 is 30-60 degrees. By designing the angle, the toggle plate 403 can have a certain inclination angle, and such an inclination angle can make the toggle plate 403 generate a vortex-like stirring force on the water body when rotating, thereby driving the water body to pass through the permeable wall 3 faster, thereby improving the water purification rate.

[0026] When the lake wetland restoration device provided by the embodiment of the utility model is used, the entire device is first placed in the lake wetland that needs to be purified, and the motor 401 is started. The motor 401 drives the connecting rod 402 to rotate, and the rotation of the connecting rod 402 drives multiple toggle plates 403 to rotate continuously. The continuously rotating toggle plates 403 drive the water flow, so that the water body continuously enters the multiple infiltration walls 3 in turn to purify the pollutants. At the same time, the continuously rotating toggle plates 403 drive the entire device to move slowly in the water body, so that the restoration device can repair and purify the water bodies in various areas of the lake.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
