Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle application equipment, and in particular to a rescue device based on a unmanned aerial vehicle. Background Art

[0002] Emergency rescue is the activity and plan of prevention, preparation, response and recovery for sudden and destructive emergencies. In the process of emergency rescue, in order to quickly and in real time understand the situation and changes at the rescue site, the application of drones for emergency rescue is becoming more and more widespread, such as search and rescue in complex environments of wild mountains and forests, aerial survey applications and inspection work.

[0003] When drones are used for rescue, aerial survey, inspection, etc., they are usually equipped with cameras to capture real-time audio and video information. For example, the public emergency rescue reconnaissance drones and systems include: a drone body and a reconnaissance device fixed under the drone body; the reconnaissance device includes: a gimbal and an onboard camera with two cameras; the gimbal is fixedly installed on the drone body, and the onboard camera is installed on the gimbal to take pictures or videos, thus realizing long-distance reconnaissance. During the entire reconnaissance process, the operator does not directly control the drone, but the drone is always flying autonomously under the control of the flight controller, thus realizing the control of the drone body for long-distance reconnaissance, saving manpower, financial resources, and material resources to a large extent, and reducing rescue costs.

[0004] However, when the drone-based reconnaissance equipment is used, the adjustment of the gimbal to rotate and take pictures or videos, coupled with the interference of the drone's flight movement, may cause unclear pictures or videos, as well as incomplete images of some areas during the rotation of the camera, which may lead to the problem of not being able to detect the target in time.

[0018] Furthermore, the connecting rod unit includes a plurality of connecting rod groups corresponding one-to-one to the adjusting seat heads, and the connecting rod groups include two hinged supporting arms, and the two free ends of the supporting arms are respectively hinged to the adjusting seat head and the sliding block.

[0019] The beneficial effect is that the connecting rod unit is driven by the conversion unit and then pulls the adjustment seat head to adjust the position, and the structure is simple.

[0020] Furthermore, a plurality of adjustment channels for accommodating the adjustment seat heads are provided in the mounting seat, the adjustment channels are communicated with the vertical cavity, and the adjustment channels gradually increase in size from the outside of the mounting seat toward the central axis.

[0021] The beneficial effect is that by setting the adjustment channel, the collision between the connecting rod unit and the inner wall can be reduced, which makes it easier to adjust the position of the seat head and reduces vibration during the adjustment process.
