Description

Technical Field

[0001] The utility model relates to the technical field of seaweed sowing, in particular to a seaweed efficient sowing unit. Background Art

[0002] With the continuous acceleration of industrialization, activities such as land reclamation, destructive dredging, aquaculture and domestic sewage discharge have directly affected the survival of seagrass. Seagrass degradation is a global problem recognized by the world. As the ecological problems of seagrass beds become increasingly severe, how to protect and restore them has become the most urgent need at present.

[0003] Artificial restoration methods for seagrass beds can be divided into habitat restoration, seed sowing and plant transplantation. Taking seed sowing as an example, it refers to collecting mature seagrass seeds from naturally well-grown seagrass beds, and then directly spreading them into the sowing sea area or burying them in the bottom, or first placing the seeds in floating cages or laboratories for cultivation, and then transplanting them after they germinate and grow into seedlings.

[0004] Although the seed sowing method has achieved some results in restoring seagrass beds, there are still some problems and weak links. For example, in seagrass-degraded waters, the sown seagrass seeds and the grown seedlings are often washed away or washed out by tides and currents, resulting in serious loss of seeds and seedlings, thus causing restoration failure. Therefore, it is urgent to solve the problem of low efficiency of seed sowing method in restoring seagrass beds. Utility Model Content

[0005] In order to solve the above technical problems, the utility model discloses a seaweed efficient sowing unit, including a counterweight frame, a mesh bag and a mesh plate, wherein a plurality of grid grooves are arranged in the counterweight frame, each of the grid grooves is provided with a mesh bag, the inner side surface of the counterweight frame is provided with strip grooves along the upper and lower sides of the grid grooves, and two through grooves are provided on one of the outer sides of the counterweight frame, the two through grooves are respectively connected with the strip grooves on the upper and lower sides of the grid grooves, and the mesh plate is inserted into the strip grooves along the through grooves.

[0006] Furthermore, the mesh bag is woven from linen and sealed with cotton thread.

[0007] Furthermore, the grid plate is made of basalt fiber, and the pore size of the grid is 5-10 mm.

[0008] Furthermore, the side length of the grid groove is 2-4 cm.

[0009] Furthermore, a plurality of lifting ears are provided at the top edge of the counterweight frame.

[0010] Furthermore, a plurality of limiting pins are provided at the bottom edge of the counterweight frame.

[0011] Furthermore, the counterweight frame is a stainless steel frame.

[0012] The beneficial effects of the utility model are:

[0013] The efficient seaweed sowing unit of the utility model contains seaweed seeds and soil through a mesh bag, and fixes the mesh bag through a counterweight frame and a grid plate, and then lowers the counterweight frame to the seabed to sow the seaweed on the seabed, thereby preventing the seaweed seeds from being washed away by the ocean current, effectively improving the survival rate and sowing efficiency of the seaweed seeds, and realizing large-scale, high-efficiency, and low-cost seaweed bed restoration.
