Automatic lifting type algae turf system and artificial algae field establishing method thereof

Abstract

Provided are an automatic lifting type algae turf system and an artificial algae field establishing method thereof. A plurality of square algae turf frames provided with mesh structures are included, and algae seedlings are arranged at each mesh. Four floaters are connected to the top ends of four right-angle bending heads of each square algae turf frame, and the bottom ends are connected with rope cables and settlers. Each square algae turf frame is fixed between two mooring ropes. The artificial algae field establishing method comprises the steps that before casting, the algae seedlings are clamped in the middle of the four sides of each mesh through algae clamps; and two anchors are cast in an incident-flow direction, after tensioning, a first square algae turf frame is cast in a downstream direction, and repeated operation is carried out in sequence. Large-area artificial algae field establishing can be achieved easily, automatic sinking can be achieved under the sea state of heavy storm wave, the safety of an algae turf and algae is protected, the structure is simple, assembling is easy, operation is convenient, cost is low, the method is suitable for large floating type algae field establishing in most sea areas in China, the application range is wide, and large market potential is achieved.

Description

technical field [0001] The invention relates to an automatic lifting algae bed system and a method for constructing an artificial algae field. Background technique [0002] Due to factors such as environmental changes, overfishing, and human development, the natural ecological environment in the coastal waters has been severely damaged, the seaweed farms in the sea area have been seriously degraded, and desertification has even occurred in many sea areas. In order to restore the coastal ecological environment, coastal countries build artificial algae reefs in the sea area to provide marine algae with multiplication and natural breeding places, so as to attract fish and other aquatic animals to feed and breed in algae farms, so as to optimize the sea area environment, protect and proliferate purpose of fishery resources. [0003] At present, my country has applied for or authorized some patents in the construction of artificial algae fields. The publication number is CN10196...

AI Technical Summary

Problems solved by technology

[0003] At present, my country has applied for or authorized some patents in the construction of artificial algae fields. The publication number is CN101960982A. The concrete triangular pyramid-shaped artificial algae reef and the seedling net covered on its surface, and the algae reef is used as the mooring point to fix the flexible algae bed in a certain water layer. The water layer is difficult to control, and when the flexible algae bed is close to the water surface, it is impossible to avoid the impact of strong wind and waves on the algae bed, and in areas with large water depths, the seabed algae reef cannot play a role due to the weak light near the seabed; the public number is CN101326894 invention patent application, titled "An artificial algae field and its construction method", provides a grid unit composed of ropes, sunken stones, etc., and attaches large seaweeds through the ropes to establish a seaweed field, but the structure also It can only be used for the restoration of seabed algae farms with relatively shallow water depth, and it is easy to be silted up by sediment

In terms of artificial algae reef patents, such as the invention application publication number CN10301794A, named "An artificial algae reef with algae attachment and seaweed transplantation", it provides an algae reef whose main body is a concrete three-dimensional frame structure that can attach algae and transplant seaweed. The scope of use of this kind of artificial algae reef can only be used in hard shallow seabeds, and cannot be deployed in a certain water layer; in addition, there are some related patents that are not listed here. On the whole, these patents are basically based on concrete structures. Main body, artificial algae reef structure arranged on the seabed

Since the growth of algae requires a certain amount of light, the deployment of these algae reefs or algae farms will be limited by the depth of the water, and the sea area cannot be effectively and fully utilized to increase the restoration effect of the algae farms on the marine ecological environment.
