Specifically, the rotating motor 106 is started, and the rotating shaft 202 rotates under the action of the rotating motor 106. The rotation of the rotating shaft 202 drives the sleeve scraper 203 to rotate, which scrapes off the contaminants on the outer surface of the cast iron 201. This prevents the humid environment at sea from accumulating and forming a corrosion layer on the surface of the cast iron 201, thus preventing rust from forming on the outer surface of the cast iron 201. This ensures that the sound produced when the hammer 104 strikes the cast iron 201 is always crisp, avoiding affecting the warning effect of the alarm and extending the service life of the alarm.

[0025] A housing 204 is fixedly mounted on the front side of the sleeve scraper 203. A small water pump 206 is fixedly embedded in the front side of the housing 204. A delivery pipe 207 is fixedly mounted on the front side of the housing 204. One end of the delivery pipe 207 is connected to the output end of the small water pump 206, and an atomizing nozzle 208 is fixedly mounted on the other end of the delivery pipe 207. The inner wall of the sleeve scraper 203 fits against the outer wall of the percussion cast iron 201. Simultaneously, the sleeve scraper 203... 3. When rotating, it can also drive the conveying pipe 207 and the atomizing nozzle 208 to rotate. When the atomizing nozzle 208 is turned on, the atomizing nozzle 208 can spray rust inhibitor onto the surface of the cast iron component 2. The rust inhibitor is stored in the box 204 and is transported to the conveying pipe 207 by the water pump. Finally, it is transported to the atomizing nozzle 208 by the conveying pipe 207 and sprayed in a mist onto the outer surface of the striking surface of the striking cast iron 201. The rust inhibitor can be a mature rust inhibitor product on the market, such as a protective wax-type rust inhibitor.

[0026] In this embodiment, the external striking electric bell assembly 1 includes an external striking electric bell body 101.

A striking hammer 104 is fixedly installed on one end of the striking rod 103.

[0027] Meanwhile, an L-shaped folding plate 105 is fixedly installed on the bottom surface of the mounting vertical plate 102, and a rotating motor 106 is fixedly installed on the back of the vertical part of the L-shaped folding plate 105.

[0028] A hollow shaft 107 is fixedly installed on the bottom front of the L-shaped folding plate 105. Mounting ears 108 are fixedly installed on both sides and the rear sides of the top surface of the external striking electric bell body 101. The alarm bell can be easily installed on the ship through the mounting ears 108.

[0029] One end of the hollow shaft 107 passes through the back of the sleeve scraper 203 and is fixedly connected to the center of the back of the striking cast iron 201. The striking cast iron 201 and the external striking electric bell body 101 can be connected through the hollow shaft 107.

[0030] One end of the rotating shaft 202 passes through the center of the hollow shaft 107 and is fixedly connected to one end of the output shaft of the rotating motor 106. The top of the outer side of the box 204 is provided with a filling port 205, which can conveniently add rust inhibitor into the box 204.

[0031] In summary, this marine alarm bell can periodically clean the outer shell of the cast iron 201 by controlling the rotation of the connecting scraper 203. This prevents rust from forming on the outer surface of the cast iron 201 in the humid and salty environment at sea, thus avoiding corrosion. This ensures that the sound produced when the hammer 104 strikes the cast iron 201 remains crisp, maintaining the alarm's effectiveness and extending its service life. Simultaneously, the rotation of the connecting scraper 203 also drives the conveying pipe 207 and the atomizing nozzle 208 to rotate. When the atomizing nozzle 208 is turned on, it sprays rust inhibitors onto the outer surface of the cast iron component 2 from all directions, allowing the cast iron 201 to better adapt to high humidity and high salt spray environments.
