Description

Technical Field

[0001] The present invention relates to the technical field of water body ecological restoration, and particularly to a water body ecological restoration device for fish habitats and a using method thereof. Background Art

[0002] The ecological restoration of fish habitats in water bodies is a crucial environmental protection task. It aims to restore the natural ecological functions of damaged water bodies, provide a suitable living environment for aquatic organisms such as fish, and effectively improve the water quality and the self-purification ability of the water body by taking comprehensive measures such as water quality purification, restoration of aquatic vegetation, and sediment treatment. At the same time, a diverse aquatic ecosystem is rebuilt, the sources of fish bait and shelter are increased, and the reproduction of fish populations and ecological balance are promoted.

[0003] With the large discharge of industrial wastewater, domestic sewage, etc., it has led to a sharp increase in algae, a decrease in dissolved oxygen, and a threat to the survival of fish. To solve this problem, the use of the plant absorption method for water body ecological restoration has become an effective means. By setting floating boards on the water surface and planting plants with the ability to absorb nutrients, the root systems of which extend into the water body, the excess nutrients such as nitrogen and phosphorus are effectively absorbed, and the degree of water eutrophication is reduced.

[0004] To repair the eutrophication problem of fish habitat water bodies, the method of planting plants on floating boards is adopted. However, to prevent the floating boards from colliding and to better absorb nutrients, the floating boards need to be fixed and arranged at intervals. However, the water flow in lakes is slow, and it is difficult to balance the enriched nutrients in the water body only by the natural flow of the water, resulting in a slow absorption rate. At the same time, the efficiency of plants absorbing nutrients will gradually decrease during the growth process. When it reaches a certain level, harvesting or replacing the plants is required, and the operation is relatively cumbersome. Therefore, a water body ecological restoration device for fish habitats and a using method thereof are proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art that the water flow in lakes is slow, it is difficult to balance the enriched nutrients in the water body only by the natural flow of the water, resulting in a slow absorption rate, the efficiency of plants absorbing nutrients will gradually decrease during the growth process, and when it reaches a certain level, harvesting or replacing the plants is required, and to propose a water body ecological restoration device for fish habitats and a using method thereof.

The cutting component includes a threaded rod and a scraping rod rotatably connected to the upper part of the floating board, as well as a movable plate, a first blade and a second blade movably connected to the upper part of the floating board. The forward and reverse rotation of the threaded rod drives the movable plate to move left and right. When the movable plate moves left, it drives the scraping rod to rotate. The rotation of the scraping rod stirs the aquatic plants planted on the floating board, so that the aquatic plants are stirred towards the direction close to the movable plate. The rotation of the second blade cuts the fixed height of the aquatic plants, so that the aquatic plants fall on the upper part of the movable plate. The rotation of the first blade further shreds the fallen aquatic plants and throws the shredded aquatic plants towards the surrounding of the water. A moving component is arranged on the floating board. The moving component includes a plurality of propeller blades rotatably connected to the bottom of the floating board, as well as a third rotating rod and an L-shaped movable pipe rotatably connected to the outside of the floating board. The rotation of the third rotating rod drives the plurality of propeller blades to rotate. The propeller blades rotate on the bottom of the water to push the floating board to move.
