Embodiment 1

[0046] Such as Figure 1-12 As shown, the present invention provides an anode device for ship protection with adjustable orientation. In this embodiment, the anode device is described with a strip structure. The distribution of the electric field at the bottom is directly related to it. In the prior art, the anode devices are all fixedly installed, and the electric field cannot be adjusted according to the structure of the bottom of the ship, resulting in the inability to maximize the protection effect on the bottom of the ship.

[0047] To this end, the anode device of the present invention includes: an anode bed 10, an anode holder 50 and an anode body. Wherein, the anode bed 10 is a cavity frame structure with an open bottom, including a top 14 and surrounding side walls 15. A circular concave cavity 19 is set in the center of the top of the anode bed 10, and a circular cavity 19 is set in the bottom of the outer periphery of the circular cavity 19. The chute 16 is arrange...

Embodiment 2

[0078] Such as Figure 13-14 As shown, on the basis of Embodiment 1, the sealing performance of the connection between the hollow rotating disk 82 and the anode bed 10 is further enhanced. A second pressure ring 85 is used to seal between the inner wall of the hollow turntable 82 and the bottom of the circular cavity 19 . The structure, connection and function of the second pressure ring 85 are similar to those of the first pressure ring 84 . Specifically, the bottom of the circular cavity 19 on the inner periphery of the hollow turntable 82 is provided with a number of third threaded holes, and the second pressure ring 85 is correspondingly provided with a number of mounting holes with a limiter in the longitudinal direction. The second pressure ring 85 is installed on the bottom of the circular cavity 19 by bolts, so as to realize the installation and fixation of the second pressure ring 85 .

[0079] The bottom of the outer wall of the second pressure ring 85 is provided w...

Abstract

The invention discloses a direction-adjustable anode device used for ship protection. A round concave cavity is formed in the center of the top of an anode bed. An annular sliding groove is formed inthe bottom of the periphery of the round concave cavity. An annular guide block is arranged at the bottom of a hollow rotary disc and is limited to rotate in the annular sliding block. Sealing betweenthe outer side wall of the hollow rotary disc and the inner side wall of the round concave cavity is achieved through a first compression ring. An anode base is mounted in a frame structure of the anode bed in an attached mode. An anode body is elastically arranged at the bottom of a cavity of the anode base and is connected with an external power supply. An inner gear ring is arranged on the inner side wall of the hollow rotary disc in the radial direction. A driving motor is arranged at the bottom of the round concave cavity. A gear is externally arranged on a driving shaft of the driving motor and is engaged with the inner gear ring. By adoption of the direction-adjustable anode device used for ship protection, the technical problem that the mounting direction of an existing anode device cannot be adjusted is effectively solved.

Description

technical field [0001] The invention relates to the technical field of ship anticorrosion, and more specifically, the invention relates to an anode device for ship protection with adjustable azimuth. Background technique [0002] The hull and steel structure in the marine environment have serious electrochemical corrosion in the seawater medium, and certain corrosion protection measures need to be taken. Paint protection technology uses paint to form a film on the surface of the protected component to play a role in corrosion protection. It is an effective method of corrosion protection and is widely used. However, due to the influence of the integrity of the film-forming coating itself, such as coating defects, collision damage, aging, capillary penetration of the coating, etc., there is still a certain corrosion effect, which endangers the safety of the hull and steel structures, and affects the follow-up maintenance costs. Therefore, further additional protection measur...
