Ecological floating bed

Abstract

The invention relates to an ecological floating bed, which comprises a floating bed substrate provided with several planting pots, a culture medium is provided in the planting pots, water permeable holes are opened at the bottom of the planting pots and the bottom of the floating bed substrate, and equal-height cutting holes are respectively provided on both sides of the planting pots. The cutting device and the limit plate, the cutting device includes a cutting channel and a cutting knife, the cutting channel includes a horizontal plate that is bent at both ends and arranged up and down, the bent ends of the horizontal plate are connected by an arc plate, and the cutting knife is located on the two horizontal plates between the bending parts of the blades with the blade facing upwards, and the back of the blade is connected to the arc plate through the return spring; the height of the culture medium is lower than the height of the horizontal plate at the bottom of the cutting channel; the bottom of the floating bed base plate is connected to one end of the traction rope, and the other end of the traction rope One end is connected with the sinker through a traction device. The invention is simple in structure, ingenious in design, stable in the water body, not easy to dump, and can also quickly remove plant stems and leaves, thereby preserving plant rhizomes to survive winter and greatly saving resources.

Description

Technical field [0001] The invention relates to the field of river water purification equipment, in particular to an ecological floating bed. Background technique [0002] Ecological floating bed is an artificial floating bed that degrades the content of COD, nitrogen and phosphorus in the water according to the principles of ecological engineering for eutrophication. It can greatly improve the transparency of the water body, and the water quality indicators have also been effectively improved. It has a good inhibitory effect on algae. The main effect of ecological floating bed for water purification is to use the roots of plants to absorb eutrophication substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients of the water body can be transferred, and the water body caused by the closed or insufficient self-circulation of the water body can be reduced. Fishy smell, eutrophication phenomenon. Ecological floating bed technol...

Problems solved by technology

[0003] However, the existing ecological floating bed is not fixed firmly, and it is easy to dump in windy weather or when the depth of the lake changes. Moreover, the ecological floating bed is not suitable for floating on the lake in winter in the north. Most of the plants on the floating bed are frozen to death, and a large number of them need to be replaced in the next spring. Therefore, it is urgent to provide an ecological floating bed with a stable structure, not easy to dump, and can quickly remove the stem and leaf parts of the plant, thereby preserving the plant rhizome and saving resources.
