Overwater emergency rescue device of unmanned aerial vehicle

[0029] Example 1

[0030] With reference to the drawings, the water emergency rescue device for drones in this embodiment includes a release control mechanism, a release bracket, a decoupling device 2, a lifebuoy 31, a rope 32 and an LED searchlight 4. Said delivery control agency (see image 3 ) Including remote control receiver, steering gear, automatic stabilization pan/tilt, camera 5 and wireless image transmission system 6, LED searchlight 4 and remote control receiver are powered by the power supply, remote control receiver and camera 5 are set on the placing bracket, and camera 5 is installed On the automatic stabilization gimbal, the automatic stabilization gimbal is fixedly connected to the placing bracket, and the remote control receiver sends a signal to control the automatic stabilization gimbal to drive the camera 5 to rotate at any angle in the XY direction. The camera 5 of this embodiment adopts a ccd high-definition camera. The camera 5 is connected to a wireless image transmitting system 6. The wireless image transmitting system 6 is also installed on the placement bracket. The wireless image transmitting system 6 transmits signals to the ground wirelessly by radio. The image receiving system then displays it on the screen. The rescue personnel on the ground can quickly find the rescued personnel by observing the images taken by the camera 5 returned by the wireless image transmission system 6. The remote control receiver is also connected to the input end of the steering gear, and the remote control receiver controls the decoupling device 2 to open by sending a signal to open the parabolic hook to the steering gear to release the lifebuoy 31.

[0031] See figure 1 with figure 2 Considering that the survival probability of rescued personnel depends on the rescue time, shortening the rescue time is the key to rescue. In order to adapt to the characteristics of water rescue and time race, this embodiment is equipped with a mount for quick disassembly on the delivery bracket A hook (not shown in the figure) through which the launching bracket can be quickly installed on the mounting rods of various aircraft floor panels. In this way, the universal applicability of the emergency rescue device of this embodiment is greatly enhanced, and it can be quickly assembled with the aircraft equipped on the rescue site and put into rescue operations in time, and the timeliness of rescue is further enhanced. The delivery support includes a support cross beam 11 and a support vertical beam 12. The decoupling device 2 is arranged at the outer end of the support cross beam 11, and the decoupling device 2 is connected to the lifebuoy 31 via a rope 32. In this embodiment, the support beam 11 is a Y-shaped structure, and the included angle of the adjacent beam legs is 120°. The Y-shaped structure of the support beam 11 ensures the connection stability of the lifebuoy 31 and the accuracy of the lifebuoy 31 placement. The life buoy 31 is fitted on the support vertical beam 12, and in this embodiment, two life buoys 31 are fitted on the support vertical beam 12, and the person waiting for rescue can quickly grab the nearest life buoy 31 and float by the buoyancy of the life buoy 31 On the water, waiting for further rescue.

[0032] In addition, in this embodiment, in order to meet the requirements of night search and rescue, an LED searchlight 4 is also provided at the lower part of the vertical beam 12 of the support. The arrangement of the LED searchlight 4 on the one hand ensures that the person to be rescued can be quickly found at night, on the other hand, it also ensures the camera 5 It can shoot water surface images clearly, help ground rescue personnel grasp the timing of the release of the lifebuoy 31, and ensure the accuracy of the release of the lifebuoy 31 at night.

[0033] See Figure 4 When there is a flood disaster or a swimmer drowns in a deep water area, the drone will quickly carry the delivery bracket to search the water surface, and the ground personnel will observe the camera 5 returned by the wireless image transmission system 6 and shoot the image to find the person to be rescued, and control it at any time The automatic stabilization gimbal drives the camera 5 to change the shooting angle. After finding the person to be rescued, the ground rescue personnel observe the launch timing through the camera 5, control the remote control receiver to send a signal to open the parabolic hook to the steering gear, the decoupling device 2 is opened, and the multiple lifebuoys 31 fall under the action of gravity. Quickly grab the nearest lifebuoy 31, float on the water with the help of the buoyancy of the lifebuoy 31, and reserve physical strength for further rescue. During night search and rescue, the installed LED searchlight 4 can also be used to guide and locate the person to be rescued.

[0034] Example 2

[0035] The waterborne emergency rescue device for drones in this embodiment is basically the same as that in Embodiment 1. The difference lies in that: the lifebuoy 31 of this embodiment is fitted on the support vertical beam 12, which is suitable for shallow rescue water. A drowning person under steady water conditions.

[0036] Example 3

[0037] The waterborne emergency rescue device for drones in this embodiment is basically the same as that in Embodiment 1. The difference is that: the lifebuoy 31 in this embodiment is fitted with 5 on the support vertical beam 12, which is suitable for complicated water surface conditions. Circumstance to ensure the effective delivery of the lifebuoy 31.

[0038] The waterborne emergency rescue device for drones described in Examples 1 to 3 can quickly reach the rescue site through drones, and the accuracy of lifebuoy placement is high, thereby greatly shortening the rescue time, and the lifebuoy will not cause secondary injury to rescuers. , The rescue success rate is high, and the structure is simple, the weight is light, and the manufacturing cost is low, which is convenient for popularization and application.
