Embodiment 1

[0019] Example 1. Place the pre-folded salvage net on the netting device of the unmanned helicopter. The cable connection between the salvage net and the cable pay-off device is established through two modes: 1. The cable winding is set at the rear of the cable connected to the salvage net; the cable winding is connected to the cable winding and placed on the cable pay-off device to form a Wire-controlled salvage net; when in use, pull out the salvage net and place it on the net holder of the unmanned helicopter. 2. The salvage net is arranged with the cable winding on the cable pay-off device. When in use, the salvage net may be placed on the net holder of the unmanned helicopter and connected to the front end of the cable winding, or the salvage net and the The front end of the cable winding is connected to form a wire-controlled salvage net, and then the salvage net is placed on the net holder of the unmanned helicopter.

Embodiment 2

[0023] Example 2. On the basis of Embodiment 1, the net holder is provided with either a single pendulum bracket that swings around one side of the swing axis, or a double pendulum bracket that swings around the two sides of the swing shaft respectively. For example, for a single pendulum bracket, the swing axis can be located at the front and rear ends of the net holder to become the front swing axis or the rear swing axis, and the corresponding bracket either swings counterclockwise around the front swing axis, or rotates clockwise around the rear swing axis Swing to release the wire-controlled fishing net placed on the bracket. For the double swing bracket, the front and rear brackets are set around the front and rear swing axes; the front bracket swings counterclockwise around the front swing axis; the rear bracket swings clockwise around the rear swing axis, that is, the two brackets are in the Under the action of self-weight and load, the wire-controlled fishing net swi...

Embodiment 3

[0024] Example 3. On the basis of Embodiments 1 and 2, the unmanned helicopter is provided with a fixed bracket; the bottom of the fixed bracket is provided with a bracket that can swing around the fixed bracket to place a wire-controlled salvage net, and a lock is provided. Fix the bracket on the fixed bracket and place the wire-controlled fishing net on the bracket.

[0025] As the first mode of embodiment 3, the four legs of the fixed bracket are divided into front and rear group legs; both the connecting rods arranged between the front group legs or the rear group legs can be used as fixed swing shafts, and A bracket that swings around this link is provided.

[0026] As the second mode of Embodiment 3, a pair of shaft holes can also be set on the front group of legs or the rear group of legs, and then the two ends of the swing shaft with the bracket are inserted into the pair of shaft holes, and the pair of shaft holes is wound around the pair of shaft holes. swing.

Abstract

The invention relates to the salvage and rescue industry on the water surface, and specifically relates to the lifesaving of people in distress on the long-distance water surface. The invention discloses a method for carrying and opening a net support device by a remote-controlled unmanned helicopter to release a wire-controlled salvage net. Rescuers at the rescue site control the operation of the remote control device; the front end of the cable winding of the cable pay-off device is connected to the salvage net to form a wire-controlled salvage net and release the corresponding cables. The rescue personnel remotely configure the salvage net release device and carry the wire-controlled salvage net The unmanned helicopter flies over the salvaged target and hovers over it. The salvage net release device releases the air-dropped wire-controlled salvage net through the net holder and covers it around the salvage target. The salvage net release device controls the opening of the net holder through an electronically controlled unlocking device; the electronically controlled unlocker unlocks the lock in the state of locking the net holder by moving the lock or swinging the lock, and the swing shaft and the support are set. The bracket on the net holder of the bracket swings downward around the swing axis to release the wire-controlled fishing net placed on the bracket.

Description

technical field [0001] The invention relates to the long-distance rescue and salvage industry, and specifically relates to the long-distance lifesaving of persons in distress. Background technique [0002] At present, the rescue method for people in distress on the sea is mainly driven by lifeguards in small boats or assault boats, approaching the people in distress and bringing them back to the big ship and then pulling them onto the big ship. Or throw the life buoy with cable to the person in distress by the crew on board, and pull it back on board by the cable after the person in distress grabs or puts on the life buoy. However, it is easy to cause people to fall into danger in the rough water, especially under the extremely bad weather and sea conditions. When a ship goes out to sea, it encounters a typhoon and the weather causes the crew to fall into danger. At this time, the sea condition does not allow to put down the boat and send personnel to rescue; only the metho...
