Problems solved by technology

From the current point of view, most ecological floating islands adopt the mode of on-site production and on-site planting, and the construction period of large-scale production is relatively long
[0006] Moreover, the existing ecological floating islands with the same structure are only suitable for planting one or several types of plants, and the planting range is narrow, which is not conducive to the planting of plants with different purification requirements for lake water bodies.
In order to be suitable for the cleaning of different water quality conditions, different plant requirements need to be adopted, resulting in the need to adopt ecological floating islands with various structures, not only the connection stability is not high, but also the operation is complicated and time-consuming

Embodiment 1

[0033] The method of using the floating island structure to control the ecology of the river channel fixes the hydroponic plants 2 on the ecological floating island block; the ecological floating island block includes a floating island body 1 with a through hole 3,

[0034] The floating island body 1 is provided with more than three card slots 5, the card slots 5 are carded with a plant fixing frame 4, and the opposite sides of the floating island body 1 are respectively provided with concave clips 6 and convex clips with matching shapes. Card out tooth 7;

[0035] The draw-in slot 5 is arranged on opposite sides of the through hole 3; the plant fixing frame 4 includes a frame body 48 snapped on the draw-in slot 5, and two draw bars 41 parallel to each other installed on the frame body 48 are installed on the The fixed rod 42 between the two clamp rods 41, the arc clip 43 arranged on the fixed rod 42, the adjustment rod 44 installed on the two clamp rods 41 and used to move to...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the structure of the adjustment clip 45 and the arc clip 43 is optimized in this embodiment, and the specific settings are as follows: figure 2 and image 3 shown.

[0043] The adjusting clip 45 is arc-shaped. The arc clip 43 is composed of two parallel arc half rings connected by a connecting rod arranged in the middle, and the connecting rod is fixed on the fixed rod 42; the adjusting clip 45 is composed of an arc half ring. ring composition.

Embodiment 3

[0045] The difference between this embodiment and Embodiment 1 or Embodiment 2 is that in this embodiment, the fixing method of the adjusting rod 44 on the clamping rod 41 is optimized, and the specific settings are as follows:

[0046] A limiting hole 46 is provided on the clamping rod 41 , and a detachable limiting rod 47 matching with the limiting hole 46 is provided at the end of the adjusting rod 44 .

[0047] Therefore, the method for fixing the adjusting rod 44 on the frame body in this embodiment is as follows: take out the limiting rod 47, and insert it into the first limiting hole 46 on the side of the adjusting rod 44 away from the arc clip 43. Can. When the hydroponic plant 2 is to be taken out, the taking out of the hydroponic plant 2 can be realized only by taking out the limit rod 47, and the operation is more convenient.

Abstract

The invention discloses a method for controlling river ecological environment by adopting a floating island structure. The invention solves the problems of the prior art that an ecological floating island is fabricated on site and implanted on site and the construction period of large-area fabrication is longer. The method comprises the following steps: fixing hydroponic plants on ecological floating island blocks, wherein each ecological floating island block comprises a floating island main body with a through hole, an indent blocking piece and a bulged blocking tooth in mutually matched shape are respectively arranged on the two opposite sides of the floating island main body, a blocking slot of the floating island main body comprises an upper blocking slot and a lower blocking slot arranged along the vertical direction and a horizontal slot is formed between the upper blocking slot and the lower blocking slot; connecting a plurality of ecological floating island blocks into an ecological floating island through indent blocking pieces and bulged blocking teeth according to the size of a lake; and putting the ecological floating island into the lake, thereby controlling the lakewater. The method is suitable for planting all the plants, the planting is more convenient and the planting time is saved.

Description

technical field [0001] The invention relates to the related field of ecological floating islands, in particular to a method for controlling river ecology by adopting floating island structures. Background technique [0002] Eutrophication of water bodies is a global water environment problem. There are more than 2,700 lakes in my country, with a total area of ​​91,000 km 2 . According to the survey data and domestic and foreign evaluation indicators of lake eutrophication, among the 37 typical major lakes in China, 55.8% are medium eutrophic and medium eutrophic, 14.7% are eutrophic, and 14.7% are heavy eutrophic. 8.8%. More than 90% of water pollution in China is caused by eutrophication caused by excessive N and P content in water bodies, while N and P are the most basic essential nutrients for plant growth. [0003] The ecological floating island is an artificial floating island that aims at eutrophic water quality and uses the principle of ecological engineering to de...
