It is a transportation station that must be equipped for various offshore platforms and ships. It is also an important location for external commuting and emergency evacuation of various offshore platforms and ships. and necessary routes for supplies.
根据国际民航组织(ICAO)的要求，无论陆地上还是船舶上直升机平台都需要配备消防***，传统的消防***包括两个或多个固定式消防炮，但是消防炮的覆盖范围受风的影响大，而且ICAO推荐使用泡沫作为消防介质，但是泡沫液本身含有化学物质，会造成环境污染，而且泡沫的有效期过后也只能报废处理，更换新的泡沫。According to the requirements of the International Civil Aviation Organization (ICAO), helicopter platforms, whether on land or on ships, need to be equipped with a fire protection system. The traditional fire protection system includes two or more fixed fire monitors, but the coverage of the fire monitors is greatly affected by the wind. , and ICAO recommends the use of foam as a fire-fighting medium, but the foam liquid itself contains chemicals, which will cause environmental pollution, and after the validity period of the foam, it can only be scrapped and replaced with new foam.
现有技术中，消防***配备的喷洒装置结构简单，喷射范围窄，雾化效果差，导致灭火效果不好。当直升机着陆发生事故漏油、引发火灾时，现有的喷洒装置需要在较长的时间内才能消灭火灾，造成的损失较大。为了对直升机平台实现消防全面覆盖，需要在平台上设置多个喷头，并且每个喷头需要有大的立体覆盖范围，目前的普通消防喷头尚无法达到上述要求。In the existing technology, the sprinkler device equipped with the fire protection system has a simple structure, a narrow spray range, and poor atomization effect, resulting in poor fire extinguishing effect. When a helicopter accidentally leaks oil and causes a fire during landing, the existing sprinkler device takes a long time to extinguish the fire, causing great losses. In order to achieve comprehensive fire protection coverage on the helicopter platform, multiple sprinkler heads need to be installed on the platform, and each sprinkler head needs to have a large three-dimensional coverage area. Current ordinary fire sprinkler heads cannot meet the above requirements.
