Description
Technical Field
The utility model relates to a cut umbrella device, especially an automatic umbrella device of cutting of unmanned aerial vehicle.
Background
In the area with high ground wind speed, after the unmanned aerial vehicle lands, the parachute cannot land due to high wind speed, a certain pulling force can be generated to pull the unmanned aerial vehicle, and under the condition that the wind speed is high enough, the unmanned aerial vehicle can be dragged to turn over or rub with the ground, so that the unmanned aerial vehicle and even internal equipment are damaged; when the unmanned aerial vehicle landing point is far away or exceeds the visual range, the umbrella can not be manually folded in time, and the machine body and the built-in equipment can be injured.
Disclosure of Invention
In order to solve the problem, the utility model provides an automatic umbrella device of cutting of unmanned aerial vehicle.
This kind of automatic umbrella device of cutting of unmanned aerial vehicle, including umbrella and organism, its characterized in that is equipped with power, gravity switch, time delay signal generator and cuts the umbrella ware in the organism, and the power is connected with the gravity switch electricity, and time delay signal generator is connected with cutting the umbrella ware electricity.
Furthermore, the gravity switch comprises a base, a cylinder is fixed on the base, a microswitch is fixed on the base, and a steel ball is placed on the microswitch.
Furthermore, the diameter of the cylinder is 0.1-2mm larger than that of the steel ball.
Furthermore, the height of the cylinder wall is 0.1-1mm larger than the diameter of the steel ball.
Further, cut the shell that the umbrella ware includes the cylinder type, be equipped with the wire of being connected with time delay signal generator electricity on the shell left end, the left part is the explosive layer of exploding in the shell, and the annular sword has been put on explosive layer right side, and the annular sword right side is the protective layer, and the right-hand porose setting of protective layer is on the shell, and the rope of umbrella passes the hole.
When the high-level-signal-type parachute cutting device is used, the delay time of the delay signal generator is set to be the average time from parachute opening to landing of the unmanned aerial vehicle, the unmanned aerial vehicle has the ground speed of 5 ~ 6m/s immediately before parachute landing and the reverse acceleration generated when the unmanned aerial vehicle lands, the gravity switch is driven to generate a high-level signal, the steel ball exerts pressure on the microswitch due to the inertia effect, the microswitch is pressed to turn on a circuit, and accordingly the high-level signal is generated, after the delay signal generator receives the high-level signal, the high-level signal is sent to the parachute cutting device after delay is carried out for several seconds, the explosive layer in the parachute cutting device is detonated after a lead of the parachute cutting device is electrified, the annular knife is pushed by the thrust generated by the explosive.
The utility model has the advantages that the cylinder with slightly larger diameter than the gravity steel ball limits the moving direction of the steel ball, and ensures that the cylinder accurately applies pressure to the microswitch at the bottom when falling to the ground; the height of the cylinder wall is slightly larger than the diameter of the steel ball, so that the micro switch is prevented from being triggered by mistake when the steel ball moves to the cylinder top and falls down due to an overlarge flying posture; the protective layer is used for protecting the main umbrella rope when the umbrella cutter is not started; after falling to the ground, the parachute is automatically cut off from being connected with the unmanned aerial vehicle in a short time, so that the unmanned aerial vehicle body is protected.
