Description

Submarine algae field forming device

Technical Field

The invention relates to the technical field of seaweed transplantation, in particular to a submarine seaweed field forming device.

Background

The algae is a typical biological community forming an algae field ecological system, the algae field ecological system is one of typical near-shore ecological systems, and the algae is used for absorbing and fixing and transferring biogenic factors such as carbon, nitrogen, phosphorus and the like in seawater to reduce the eutrophication of a water area and simultaneously form a local stable niche for the growth and inhabitation of various marine organisms so as to achieve the purposes of increasing the biological diversity and restoring fishery resources.

Through retrieval, a patent with application number CN201610576590.1 discloses a submarine algae field forming device, which comprises an underwater robot and other devices, and when the device works, a vertical scraping tooth is moved on the seabed by a machine frame to scrape a strip of groove on a submarine substrate, so that seaweed spore mixed slurry with certain viscosity sprayed out of a vertical discharge pipe can be coated in the corresponding groove, and the stability of the seaweed spore mixed slurry adhered on the submarine substrate is improved, and the seaweed spore mixed slurry is not easy to wash away by ocean current.

Although the spores can be well coated in the substrate groove, the frame part has a large structure and is always in a walking state, so that obvious disturbance is inevitably caused to the surrounding water body, the density of the seabed substrate and seawater is not high, the disturbance of the water body easily causes the surrounding substrate to be dissipated in the water body around the frame and washed away with water flow, and the spores coated in the groove are difficult to avoid in the process, so that the effect of transplanting the seaweed in the actual use process is general. Based on this, this application provides a seabed algae field forming device that disturbance is little to seabed matrix, improves the marine alga effect of transplanting.
