It can be understood that the theoretical critical height of the lifting device of the aerial ladder fire truck and the fire truck adopted at present is 50m, and the actual achievable height is only 30 m; and when used in crowded cities, the size, use conditions, number and the like of the urban public are severely limited. Therefore, the response time of high altitude rescue is slow, and the efficiency is low.
And unmanned aerial vehicle 9 has then broken through the restriction in special place and complex environment, and flying speed is fast, consequently, can the quick response rescue demand, efficient. In the embodiment, a temporary platform or a temporary channel is built to implement rescue by combining the unmanned aerial vehicle 9 with the high-altitude rescue platform, various rescue schemes can be flexibly and changeably adjusted in actual application, and a new form and thought are provided for the high-altitude rescue scheme.
In consideration of the specific implementation mode that the unmanned aerial vehicle 9 carries the high-altitude rescue platform, on the basis of the above embodiment, the unmanned aerial vehicle 9 is provided with a mechanical arm for grabbing and loosening the high-altitude rescue platform; or, the unmanned aerial vehicle 9 is provided with a hanging part for detachably hanging the high-altitude rescue platform.
That is, the high altitude rescue platform can be fixed or released by grabbing or loosening the mechanical arm; or the high-altitude rescue platform is fixed or separated from the unmanned aerial vehicle 9 through the hanging part.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
