Description

I UNMANNED AERIAL VEHICLE FOR RESCUE TECHNICAL FIELD

[1] The disclosure relates to the technical field related to unmanned aerial vehicles, in

particular to an unmanned aerial vehicle for rescue.

BACKGROUND

[2] The unmanned aerial vehicle (UAV) is mainly remotely controlled by radio, it is flexible

in use, such as flying to a higher area to obtain a large amount of visual spatial information. It

can also complete a large amount of data analysis and processing work with machine vision and

corresponding processing modules, including identifying objects and deciding how to deal with

these objects. For example, the workload of the water safety inspector can be effectively reduced

during the water area patrol, the aerial view can facilitate the safety inspector to better find the

abnormal situation, so as to facilitate timely rescue.

[3] However, there are still some problems when the existing UAVs perform auxiliary patrol

in surface water rescue:

[4] 1. The existing unmanned aerial vehicle (UAV) surface water patrol usually relies only

on the camera for video recording and identification, and lacks the corresponding auxiliary

measures for water rescue, such as identifying dangerous objects such as sharks, calling for

warning, and releasing auxiliary rescue items. The additional independent speakers and mounted

delivery bin need to take up a lot of space, which is likely to affect the camera shooting, but also

limited by the load capacity of ordinary UAVs, and is also inconvenient to mount a large number

of additional independent functional units.

[5] 2. At the same time, the existing mounted delivery bins of the unmanned aerial vehicle

(UAV), such as the water rescue UAV delivering device with the Chinese patent publication

number of CN210364321U, can release the life bomb by powering off the electromagnet and

opening the steering gear lock to facilitate the release of the corresponding rescue tools. The existing delivering mechanism often requires additional control methods to adjust the delivering, increasing the complexity and inconvenience of the control operation, and the control delivering structure itself will also take up the limited space. So there lacks a special function related rescue

UAV for surface water auxiliary patrol and rescue.

[6] In view of the above problems, innovative design is carried out on the basis of the

original rescue UAV.

found and rescue is needed, the UAV body moves to the place where it occurs, the tweeter and

the camera then deflect downward to warn the area and keep observing, and trigger the release of

the limit moving block with the deflection of the deflection movable seat, so that the rescue

items can be put in automatically when reaching the rescue area, which is convenient to use and
