Problems solved by technology

However, regardless of whether the launching device is controlled, the externally powered cold launch mode or the hot launch mode is used to launch the wire-controlled salvage net device, there are complex devices, long launch preparation time, difficult to determine and inaccurate launch parameters, high cost, and poor mobility. Flaws and deficiencies in dealing with the sudden change and randomness of salvage and rescue site conditions. The above situation has always been a serious problem faced by the long-distance rescue and rescue or rescue and salvage in dangerous places, especially the sea or river surface salvage and rescue industry, which seriously affects and restricts remote rescue. The development of salvage operations

Embodiment 1

[0023] 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 device; when in use, pull out the salvage net and place it on the net support device 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 support net device 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 device, and then the salvage net is placed on the net support device of the unmanned helicopter.

Embodiment 2

[0027] Example 2. On the basis of embodiment 1, the unmanned helicopter is provided with a decoupling device; one end of the salvage net placed on the net device is hung on the decoupling device; the net device controlled by the unmanned helicopter opens the salvage net of the airdropped cable And tow the salvage net to fly, and then control the decoupling device to separate from the salvage net with the cable after it is determined that the towed salvage net covers the salvage target. After the unmanned helicopter tows the salvage net and hovers over the salvage target at a lower height, and needs to release all the wire-controlled salvage nets, then control the decoupling device to release the net, so that the salvage net with the cable can accurately cover the salvage target. In order to make the towed salvage net accurately cover the salvage target, the decoupling device is usually controlled to release the net when the unmanned helicopter is in a hovering state.

Embodiment 3

[0028] Example 3. On the basis of Embodiment 2, the unmanned helicopter is also provided with an external force sensing device; when the external force sensing device senses that the external traction force on the salvage net is greater than the preset limit value, it directly controls the uncoupling device to go off the net, and the associated The fishing net for the cable is separated.

[0029] As another mode of embodiment 3, after the external force sensing device of the unmanned helicopter senses that the external traction force on the salvage net is greater than the preset limit value, the relevant information is sent back to the remote control device, and the rescue personnel at the rescue site decide whether to The decoupling device that needs the remote control unmanned helicopter to go off the net and separate from the salvage net with the cable. Embodiment 3 belongs to the active separation mode.

Abstract

The invention relates to the water salvage rescue industry, in particular to rescue of persons in distress on remote water, and discloses an unmanned helicopter remote rescue salvage method of a wire-controlled salvage net device. A rescue work in a rescue place controls a remote control device to operate; the front end of a cable winding of a cable unwinding device is connected with a salvage net to form the wire-controlled salvage net device, and corresponding blades are released; the rescue worker in the rescue place remotely controls arrangement of a net support device, and controls an unmanned helicopter with the salvage net device to fly above a salvaged target; the support net device is opened for air drop of the wire-controlled salvage net device; the wire-controlled salvage net device flies to unfold for covering the salvaged target; the cable unwinding device releases the corresponding cables along with flight of the unmanned helicopter; a connecting relation is built between the rescue place and the salvaged target; and the salvage recovery is performed through the cables.

Description

[0001] Title of prior application: Water surface long-distance salvage method with wire-controlled salvage net device [0002] Prior application number: 201610293947.5 technical field [0003] 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 [0004] 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 typ...
