A barnacle removal device

Abstract

The invention discloses a clearing device for barnacles. The clearing device for the barnacles comprises a shell, outer cutters and inner cutters. The shell comprises an outer shell and an inner shell which are connected into a whole; the outer cutters are arranged at the lower edge of the outer shell and protrude outwards; the inner cutters are arranged between the inner shell and the outer shell; lowermost ends of the inner cutters are lower than the lower edge of the outer shell and the lower edge of the inner shell; and the shell is driven by a power plant to rotate. As the clearing device comprises the outer cutters and the inner cutters, during a brushing process, the shell is driven by the power plant to rotate, the outer cutters and the inner cutters rotate along with the rotation of the shell, blocky dirty substances connected together are cut off by the outer cutters for preliminary clearing, and fine clearing is performed by using the inner cutters, and therefore, barnacles are thoroughly cleared. The clearing device is simple in structure and obvious in brushing effect, especially very good in barnacle brushing effect.

Description

technical field [0001] The invention relates to a removal device, in particular to a barnacle removal device. Background technique [0002] Barnacles are calcareous shellfish attached to reefs and hulls. Its shell is extremely hard, and it also secretes a viscous barnacle primary gum, which contains a variety of biochemical components and strong adhesive force , so as to ensure its strong adsorption capacity. It is almost impossible to pull it directly from the attachment by hand. It must be knocked off with the help of hard metal like a chisel. Therefore, barnacles are known as the most difficult to clean among the hull fouling marine life. Every year, the world spends a huge amount of manpower and funds on removing barnacles and researching and developing various technologies and coatings to prevent barnacles from attaching, but with little success. After investigation, it is found that it is almost unrealistic to prevent the growth of barnacles, especially on the surfa...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a barnacle removal device, which solves the problem that barnacles are difficult to clean up, especially in terms of the hull, after the barnacles on the surface of the hull are cleaned, the friction between the hull and seawater is reduced resistance, extending the life of the hull
