Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] see figure 1 and figure 2 , Ship engine room multifunctional helmet-type anti-noise earmuffs include safety helmet 1, searchlight 2, noise protection earmuffs 3, intercom equipment 4, bone conduction earphone 5, bone conduction microphone 6, PTT button 7 and large-capacity portable mobile phone power supply8.

[0029] The safety helmet 1 has a hemispherical shape, adopts a steel shallow dome, is firm, smooth and elastic to a certain extent, can buffer and disperse instantaneous impact force and is often breathable; it is suitable for different head shapes and provides comfortable ear space. The safety helmet 1, as the whole skeleton part of the inventive equipment, can directly avoid or alleviate the impact injury to the head in th...

Abstract

The invention provides a multifunctional helmet type anti-noise earshield for a marine engine room. The earshield is characterized by comprising a safety helmet, anti-noise protective earshield bodies, a bone-conductive earphone, a bone-conductive transmitter, talk back equipment, a searchlight and a high-capacity portable power source. The integral structure of the earshield is a helmet type noise-prevention earshield, and sound-proof cotton backing, the bone-conductive earphone and the bone-conductive transmitter are arranged in the earshield. The multifunctional helmet type anti-noise earshield has the advantages that when making an inspection tour on the engine room for maintenance, a marine engineer wears the anti-noise earshield, the marine engineer can be protected from noise interference under the high-intensity noise environment of the engine room, meanwhile, signals can be accurately received and transmitted through the talk back equipment, the bone-conductive earphone and the bone-conductive transmitter, the marine engineer can communicate with a marine engineer on duty in an engine control room, and discomfort caused by long-time wearing of the earshield is alleviated; through the integrated multifunctional design, the problem that when making an inspection tour, the marine engineer carries excessive equipment is solved, and the marine engineer can work more safely and more efficiently.

Description

technical field [0001] The invention relates to an earmuff, in particular to a multifunctional helmet-type anti-noise earmuff for a ship engine room. Background technique [0002] On most current ships with diesel engines as the main engine, the power machinery (main engine, auxiliary engine, propeller, propulsion system, etc.) and auxiliary machinery (pumps, fans, etc.) will make huge noises during operation. This kind of noise is not only related to the safety of sailing, but also harmful to human health when working in this environment for a long time. Therefore, it is necessary to wear anti-noise earmuffs during the inspection and maintenance of the cabin. However, ordinary noise-proof earmuffs will feel stuffy and tight when worn for a long time. [0003] When the ship is sailing normally, the engineers shall make normal inspections at least once an hour. Under normal circumstances, when an engineer encounters a problem in the engine room inspection, he always return...
