Description

Name of the invention: artificial wetland water plant cleaning device

Technical field

[0001] The present invention relates to the field of sewage treatment technology, and specifically relates to an artificial wetland water plant cleaning device.

Background technique

[0002] As a new type of ecological sewage purification treatment method, the artificial wetland system water purification technology is based on the cultivation of specific wetland plants on the constructed wetland fillers, thereby establishing an artificial wetland ecosystem. When the sewage passes through the wetland system, the pollutants and nutrients are absorbed or decomposed by the system, and the water is purified. The key to water purification in constructed wetland systems is the choice of process and the choice and application of plants. Therefore, the scientific selection and configuration of aquatic plants is of great significance for the construction of constructed wetland systems and landscapes.

[0003] Aquatic plants refer to plants that grow in water bodies and marshes, including herbs and woody plants. At present, the commonly used classification method in China is to classify aquatic plants into four categories: (1) Standing water plants. The water-producing plants refer to aquatic plants with stems and leaves that come out of the water. Common are lotus, yarrow, calamus, cattail, yellow iris, swallow flower, sage, reed, rush, pampas grass, etc. (2) Floating leaf plants. A floating leaf plant refers to an aquatic plant whose leaves float on the surface of the water. Commonly, there are Eichhornia crassipes, Wang Lian, Water Lily, Pampas Grass, and Fructus Lycii. (3) Floating plants. The roots of the floating plant are not born in the mud. Some of the plants float on the surface of the water and are partially suspended in the water, such as Manchurian, leeches, duckweed and so on. (4) Submerged plants. The entire plant of the submerged plant is not in the water, or only a few tips or flowers on the surface of the water, such as goldfish, alfalfa, bitter grass, spirulina and so on.

technical problem

[0004] The configuration of aquatic plants in constructed wetlands should not only take into account its landscape effects, but also take into account its ecological benefits. To form a well-behaved plant community, it is possible to truly achieve the benefits of sewage treatment. It also serves to beautify the rich water landscape and maintain biodiversity. Therefore, when some plants are overgrown, they need to be controlled by cockroaches. Among them, the water-stopping plants grow very fast because of their vitality, but it is difficult to clean them quickly and effectively. It usually relies on manual removal, but it is inefficient and unsafe due to working in wetlands.

Embodiments of the invention

[0017] A specific embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the artificial wetland water plant cleaning device includes a floating plate 1, the floating plate 1 is a flat surface with a smooth bottom surface, and the front end of the floating plate 1 A cutting piece 3 is mounted, the shaft 4 of the cutting piece 3 is vertically mounted; the shaft 4 is mounted in the casing 9, the casing 9 is mounted above the floating plate 1, and the front end of the casing 9 is a curved surface. A gap is left between the lower surface of the chassis 9 and the floating plate 1; the cutting piece 3 is installed between the chassis 9 and the floating plate 1; the front end of the floating plate 1 is also fixed with a cable hole, and the cable hole is used for The fixed cable is connected to the power unit, and is pulled by the power unit to the floating plate 1 to move on the wet ground.
