Description

Technical Field

[0001] The invention relates to the technical field of fishery breeding, in particular to a corrosion-resistant transformation method of a bamboo pole used for breeding Porphyra haitanensis. Background Art

[0002] Due to reasons such as aging due to sunlight, corrosion due to insects, and damage caused by wind and waves, the lifespan of bamboo poles used in the cultivation of Porphyra haitanensis is usually only one cultivation cycle, and the labor intensity of replacing them every year is extremely high. Therefore, after the harvest of Porphyra haitanensis, most of the bamboo poles are abandoned in the sea or float in the nearshore waters, breeding attached organisms such as barnacles, borers, mosses, and polychaetes. The partial rotting and decomposition of the root piles throughout the sea area also aggravates the black and smelly phenomenon of the bottom mud in the sea area, and is also prone to induce large-scale diseases of Porphyra haitanensis, seriously endangering the sustainable and healthy development of the Porphyra haitanensis cultivation industry, seriously polluting the marine ecological environment and affecting maritime traffic safety, which has become a focus of common concern among all sectors of society.

[0003] In recent years, the fiberglass rod materials promoted by local governments have high strength and corrosion resistance, which can temporarily alleviate the environmental aesthetics of bamboo waste. However, the one-time investment is too high, and the comprehensive use cost is at least 10 times that of bamboo. At the same time, the environmental hazards of microplastics caused by the aging of a large number of fiberglass materials in the sea area should also be considered. Therefore, it is urgent to organize the use of new materials for the production of Porphyra haitanensis, which is conducive to the continuous promotion of the construction of a new demonstration area for shallow-sea Porphyra haitanensis cultivation in the nearshore waters with orderly production and ecological protection. Summary of the invention

[0004] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a method for corrosion-resistant transformation of bamboo poles used for cultivating Porphyra haitanensis, which transforms the bamboo poles into corrosion-resistant ones, prolongs the service life of the bamboo poles, reduces the labor intensity of offshore operations for replacing materials, and reduces the comprehensive cost of investment in cultivating Porphyra haitanensis.

[0005] The technical solution of the present invention is a corrosion-resistant transformation method of bamboo for cultivating Porphyra haitanensis, which comprises at least the following steps: S1, selection of bamboo and control of water content: select bamboos over 3-4 years old, store them in a rain-proof place, keep them ventilated and dry, and keep the water content of the bamboo below 20%; S2, remove the irregular protrusions on the surface of bamboo, and remove the bamboo nodules or hard nodules with sharp protrusions on the surface; S3, dust removal and polishing, using a dust removal and polishing device to remove dust and polish the surface of the bamboo to make the surface of the bamboo smooth; S4, spraying primer, spraying primer on the bamboo treated in S3 using a spraying device; S5, spraying waterproof topcoat, using a spraying device to spray polyurea waterproof topcoat on the bamboo that has been sprayed with primer in S4; S6, leaving the bamboo sprayed with the polyurea waterproof topcoat to rest for storage for subsequent use; Among them, the dust removal and polishing device in S3 includes a fixed frame, at least two first rollers and two second rollers, the first roller and the second roller are arranged on the fixed frame, the first roller is arranged above the second roller, and is separated from the second roller to form a dust removal and polishing area for bamboo to enter, and a plurality of brush groups are provided on the first roller and the second roller, and each brush group is spirally distributed along the length direction of the roller to drive the bamboo to slide automatically when the roller rotates. The dust removal and polishing device also includes a first drive component for driving the first roller to rotate and a second drive component for driving the second roller to rotate.

[0006] By adopting the above technical scheme, 3 to 4 bamboos with a length of more than 9 to 14 meters are selected, and each bamboo is naturally dried to prevent surface cracking or bamboo distortion. The protrusions on the bamboo surface, especially the nodules, are manually removed so that the paint after subsequent spraying can be better attached to the bamboo surface to avoid damage caused by impact or extrusion, which cannot play a corrosion-resistant effect. The brush on the roller is used to remove dust and polish to enhance the adhesion between the bamboo and the primer. The upper and lower rollers are set so that the bamboo will not deviate when it moves under the drive of the roller, and the bamboo can be fully dusted and polished. The polished bamboo is sprayed with primer and polyurea waterproof topcoat through spraying equipment, and is left to stand still after spraying. This can extend the service life of the bamboo, reduce the labor intensity of offshore operations involving a large number of material replacements, reduce the comprehensive cost of Porphyra haitanensis cultivation, and reduce pollution.

[0007] The present invention is further configured as follows: each first roller is provided with a plurality of first bristle groups and second bristle groups, the bristles of the first bristle groups are longer than those of the second bristle groups, and a group of second bristle groups is provided between two adjacent first bristle groups.

[0008] With the above further arrangement, the bristles of the first bristle group drive the bamboo to move, and the bristles of the second bristle group are harder and process the bamboo skin to achieve dust removal and polishing.
