Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0028] Such as Figure 1-3 As shown, an ecological restoration device and a net blocking device in a semi-enclosed sea area include a soft floating raft, the soft floating raft strut 17 and two cables 11 parallel to each other, equal in length and consistent with the direction of seawater currents . The cable 11 is a blended rope, the single rope adopts 3 strands, each strand is 1:1 vinylon and plastic monofilament mixed twisted, the length is 60m, and the diameter is 2-4cm. The front and rear ends of the cable 11 are provided with piles 1, and the bottom of the piles 1 is fixed on the seabed to prevent the whole device from being washed away by seawater. The two cables 11 are parallel to each other and in the same direction as the seawater current, which can reduce the impa...

Abstract
The invention discloses an ecological restoration device for a semi-enclosed sea. The ecological restoration device comprises a soft buoyant raft, wherein the soft buoyant raft comprises supporting rods I and two cables parallel to each other, the lengths of the two cables are equal, the directions of the two cables are the same as the direction of seawater, and piles fixed in a seabed are arranged at the front ends and the rear ends of the cables; the front ends and the rear ends of the cables are fixedly connected through the supporting rods I respectively, a plurality of ropes for inserting seedlings, parallel to the cables, are arranged between the two cables in parallel in a suspended manner, the front ends and the rear ends of the ropes for inserting seedlings are also fixedly connected onto the supporting rods I, and seaweed is suspended on the ropes for inserting seedlings; the piles are fixedly connected with pile cables, and two introducing cables fixedly connected with the two ends of the supporting rods I respectively extend outwards at the positions of the nodes of the pile cables. The content of dissolved oxygen in a restoration sea area can be improved, the degradation rate of pollutants containing carbon, nitrogen and phosphorus in a water body is accelerated, and the pH of the water body is improved, so that the water quality is obviously improved, a large quantity of aquaculture products such as seaweed and sea urchin can be harvested, and huge economic benefits are obtained.
Description
technical field [0001] The invention belongs to the technical field of marine ecological restoration devices, and in particular relates to an ecological restoration device for a semi-enclosed sea area and a method for using the same. Background technique [0002] Laver, Gracilaria, kelp, sargassum and other large economical seaweeds, as important primary producers in sea areas, have the advantages of long life cycle and fast growth; as marine plants, they can absorb carbon, nitrogen and carbon in water through photosynthesis. Phosphorus and other inorganic substances are used to assimilate their own organic substances. Large economic algae continuously absorb nitrogen and phosphorus from the marine environment. When they grow to a certain size, they can be easily harvested from sea areas to land. Removed from the ocean. Therefore, macroalgae are known as biofilters in the marine environment. The introduction of large-scale economic algae to control seawater eutrophication...
