Description

Technical Field

[0001] The utility model relates to the technical field of environmental governance, and in particular to a new ecological floating island for water purification. Background Art

[0002] In recent years, a large amount of industrial and agricultural wastewater and domestic sewage has been discharged into rivers, lakes and reservoirs, resulting in excessive nitrogen and phosphorus in the water, causing eutrophication of the water. Due to the limited self-purification capacity of river water, if the eutrophic water is not treated, it will turn black and smelly. The main methods for treating eutrophication of water bodies include adding chemicals to kill algae, dredging and controlling bottom sediment, and diverting water to flush silt, but these methods have problems such as secondary pollution, high cost, and treating the symptoms but not the root cause.

[0003] Ecological floating islands use the absorption and adsorption of microorganisms and plant roots to purify water bodies, thereby reducing the nitrogen and phosphorus content in polluted water bodies. Ecological floating islands have been widely used due to their low cost and no secondary pollution. During the growth of plants, a large number of fallen leaves will be produced. These fallen leaves will accumulate on the ecological floating islands and enter the water body under the action of wind and waves. Since a large amount of nutrients will be produced when the fallen leaves rot, the purified water body will be polluted again. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a new ecological floating island for water purification.

[0005] The technical solution of the utility model is: a new ecological floating island for water purification, comprising a floating island base plate, a stuffing box fixedly arranged below the floating island base plate, and a cleaning device arranged in the middle of the floating island base plate; a storage tank for storing plant fallen leaves is provided on each side of the floating island base plate;

[0006] The cleaning device includes a lifting bar disposed laterally above the floating island substrate and vertically slidably connected to the floating island substrate, and a plurality of cleaning components disposed on the floating island substrate;

[0007] Each cleaning assembly includes two cleaning blocks symmetrically arranged on both sides of the lifting bar, used to push the fallen leaves into the storage tank, and the cleaning blocks are hinged to the lifting bar through a first connecting rod;

[0008] A first through slot is provided on the floating island base plate, a crank for driving the lifting bar to move up and down is rotatably provided in the first through slot, and the crank is hinged to the lifting bar through a second connecting rod, and a driving mechanism for driving the crank to rotate is provided on the floating island base plate.

[0009] Description: The above ecological floating island can be rotated by the crank, so that the second connecting rod drives the lifting bar to move up and down. When the lifting bar descends, the lifting bar will push the cleaning block to both sides through the first connecting rod, so that the cleaning block pushes the fallen leaves into the storage tank, avoiding the accumulation of fallen leaves on the ecological floating island and reducing the re-pollution of the water body by fallen leaves.

[0010] Furthermore, the stuffing box has a stuffing layer and an activated carbon layer.

[0011] Description: The activated carbon layer can absorb pollutants generated in the water body, and the microorganisms attached to the filler layer can degrade the pollutants and improve the water purification effect.

[0012] Furthermore, an aeration pipe is provided in the stuffing box, and an air pump for supplying air to the aeration pipe is provided on the floating island base plate.

[0013] Description: Aeration pipes can aerate water, increase the oxygen content of the water, and improve the degradation effect of microorganisms on pollutants.

[0014] Furthermore, a second through slot is provided on the floating island substrate on one side of the first through slot, an air intake bin is fixedly provided in the second through slot, and an impeller for driving the crank to rotate by inflating with an air pump is provided in the air intake bin.

[0015] Description: When the air pump is inflated, it can push the impeller to rotate, so that the impeller can drive the crank to rotate during the aeration process, so that the ecological floating island does not need to be equipped with a motor as a whole, which can effectively save energy.

[0016] Furthermore, the floating island substrate is slidably connected to the lifting bars through a plurality of sliding rods provided thereon, and the upper ends of the plurality of sliding rods are fixedly connected to the solar panels.

[0017] Description: The sliding connection between the sliding rod and the lifting bar can effectively prevent the lifting bar from falling off, and the solar panel can charge the ecological floating island to reduce energy consumption.

[0019] Note: When the lifting bar descends, the annular air bag can be squeezed to release the gas in the annular air bag through the purge hole to improve the cleaning effect of the cleaning block on fallen leaves.

[0020] The beneficial effects of the utility model are:

[0021] (1) The ecological floating island of the utility model can drive the lifting bar to descend by the crank, so that the cleaning blocks are separated to both sides and the fallen leaves are pushed into the storage tank, thereby preventing the fallen leaves from accumulating on the ecological floating island and reducing the secondary pollution of the water body by the fallen leaves.
