Description

Technical Field

[0001] The utility model relates to the technical field of ship anti-corrosion, in particular to a sacrificial anode for a high-speed metal ship. Background Art

[0002] As is well known, most metal ships are equipped with sacrificial anodes to protect the hull structure from seawater corrosion. However, for high-speed ships, installing the sacrificial anode on the outer surface of the ship's hull like the traditional method will increase resistance and is not conducive to the speed of the ship.

[0003] Among them, the sacrificial anode for a high-speed metal ship proposed in the prior art with the authorized publication number of CN112323072A includes a mounting base and a sacrificial anode assembly. The mounting base is arranged on the hull and its bottom end is connected to the outer plate of the ship's hull. An installation groove is arranged on the mounting base, and the sacrificial anode assembly is adapted in the installation groove. The lower end surface of the sacrificial anode assembly is flush with the lower end surface of the outer plate of the ship's hull.

[0004] The equipment in the prior art is inconvenient for the reinstallation operation of the sacrificial anode after use. Installing the sacrificial anode on the outer surface of the ship's hull like the traditional method will increase resistance and is not conducive to the speed of the ship. For this reason, we propose a sacrificial anode for a high-speed metal ship. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a sacrificial anode for a high-speed metal ship, which is more convenient for the reinstallation operation of the sacrificial anode after use. The embedded installation of the sacrificial anode is conducive to the speed of the ship, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a sacrificial anode for a high-speed metal ship, including an external protection installation shell, an anode fixing unit, a connection unit and a fixing unit;

[0007] External protection installation shell: an anode fixing unit is installed inside;

[0008] Anode fixing unit: includes connecting fixing columns, an internal installation shell, fixing holes one, installation frames and filtering holes. The front and rear ends inside the external protection installation shell are respectively fixedly connected with two connecting fixing columns. The inner sides of the connecting fixing columns are fixedly connected with an internal installation shell. Two fixing holes one are respectively opened at the front and rear ends of the internal installation shell. An installation frame is slidably connected inside the internal installation shell. A plurality of filtering holes are opened at the lower end of the installation frame. Two fixing holes two are respectively opened at the front and rear ends of the installation frame;

[0009] Connection unit: installed on the anode fixing unit and the external protection installation shell;

[0010] Fixing unit: Installed on the anode fixing unit.

[0011] The anode is fixed and limited by the mounting bracket. The anode can be connected to seawater through the filter holes. The anode is limited by the second fixing hole and the first fixing hole. The internal mounting shell is fixed inside the external protective mounting shell through the connecting fixing column.

[0012] Furthermore, the connecting unit includes a hydraulic press and an extrusion plate. The upper end of the inner side of the external protective mounting shell is fixedly connected with a hydraulic press. The lower end of the outer side of the hydraulic press is slidably connected with the internal mounting shell. The lower end of the hydraulic press is fixedly connected with an extrusion plate. The hydraulic press drives the extrusion plate. Since the lower end of the anode is continuously corroded by seawater, it is necessary for the hydraulic press to drive the extrusion plate to push the anode downward, and at the same time prevent the anode from floating due to the action of seawater.

[0013] Furthermore, the connecting unit also includes an infrared sensor, an anode connecting plate, a connecting guide block and a connecting hole. Two anode connecting plates are respectively fixedly connected to the left and right ends of the internal mounting shell. Two infrared sensors are fixedly connected to the left and right ends of the internal mounting shell. The two ends of the connecting guide block pass through the external protective mounting shell and are fixedly connected with the anode connecting plate. A connecting hole is fixedly connected to the middle of the connecting guide block. The anode is detected by the infrared sensor to check whether the anode has been corroded completely under the erosion of seawater. The anode is contacted through the anode connecting plate, and the cathode is connected outward through the connecting guide block to play a protective role.

[0014] Furthermore, the fixing unit includes a moving block and a limiting column. A moving block is slidably connected to the connecting fixing column between the external protective mounting shell and the internal mounting shell. The lower end of the moving block is fixedly connected with a limiting column. The limiting column is slidably connected with the second fixing hole and the first fixing hole respectively. The moving block is limited by the connecting fixing column, and the limiting column passes through the first fixing hole and the second fixing hole respectively, so as to achieve the purpose of fixing the anode.

[0015] Furthermore, the fixing unit also includes a biaxial motor and a screw rod. Two biaxial motors are fixedly connected to the upper end of the first fixing hole. The output shaft of the biaxial motor is fixedly connected with a screw rod. The screw rod is threadedly connected with the upper end of the moving block. The rotation of the biaxial motor drives the screw rod to rotate. Under the action of the thread, the screw rod and the moving block drive the limiting column to fix the anode.

[0016] Furthermore, it also includes an anode. An anode is slidably connected to the inner side of the mounting bracket. The anode is used to protect the ship.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sacrificial anode of this high-speed metal ship has the following advantages:

[0018] 1. This sacrificial anode for high-speed metal ships is more convenient for the reinstallation operation after the sacrificial anode is used up. The moving block is limited by the connecting fixing column, and the limiting column passes through the first fixing hole and the second fixing hole respectively, so as to achieve the purpose of fixing the anode.

[0019] 2. This sacrificial anode for high-speed metal ships is beneficial to the rapidity of the ship through the buried installation of the sacrificial anode. At the same time, it is installed on the hull and its lower end is welded to the outer plate of the ship. The lower end face of the sacrificial anode is flush with the lower end face of the outer plate of the ship, so as to reduce the navigation resistance of the high-speed ship and improve the rapidity of the ship.
