The helicopter salvage auxiliary device provided by the invention can position rapidly, and send the fixed safe belt to people waiting for salvage; moreover, the salvage rope is stable because of the spacing effect of the connecting ring and the fixed rope, and is prevented from swinging randomly because of sea wind in the salvage process; the salvage safety coefficient increases; the salvage efficiency is improved.
Description
Technical field
The invention belongs to rescue at sea equipment field, be specifically related to a kind of helicopter rescue at sea auxiliary device.
Background technology
Along with the development of art of navigation, sea route is more and more busier, but due to maritime affairs sea situation complexity, some perils of the sea occurs unavoidably, once occur, the rescue personnel that survive will be very urgent.And helicopter is a kind of quick good rescue at sea instrument, it can go to spot, puts down rescue rope, will the personnel of surviving rescues and boards a plane.But, conventionally all can there be large wind and wave impact in sea, cause rescuing rope showy indefinite, can not transfer to rapidly and accurately the personnel of surviving at one's side, waste so undoubtedly the valuable rescue time, simultaneously in rescue process, if rope is significantly swung by windage, also very dangerous, once personnel fall, the personnel of surviving are just caused to secondary injury.
Summary of the invention
The technical matters that the present invention solves has been to provide a kind of helicopter rescue at sea auxiliary device, this device is mainly realized rescue process by two ropes, wherein one is stationary rope, there is weak elasticity, one end of rope connects projector, the other end is connected with controllable magnetic positioning seat, projector penetrates stationary rope after aiming at location, make magnetic force positioning seat be adsorbed on the deck of ship or other metal surface, play fixation, another root rope is rescue rope, be used for bundling the personnel that fixedly survive, coupling link links together parallel with stationary rope rescue rope, in the time packing up rescue rope, just can be spacing as relying on taking stationary rope, avoid rescuing the significantly swing of rope, ensure personnel's life security, improve rescue efficiency.
Technical scheme of the present invention is: a kind of helicopter rescue at sea auxiliary device, it is characterized in that comprising winch, projector, stationary rope, magnetic force positioning seat, rescue rope, fixing safety strap, coupling link and rope pull monitoring device, wherein winch and projector are fixed on helicopter base plate, described stationary rope has weak elasticity, its upper end is connected with projector, lower end is connected with magnetic force positioning seat, the radius of this magnetic force positioning seat is 15-20cm, tension magnetic force is 1500-2000kg, electromagnetic module is equipped with in its inside, by switch control current lead-through, the control path of magnetic force positioning seat is arranged at stationary rope inside and is connected with the power supply of helicopter, described rope pull monitoring device is arranged at the bottom of stationary rope, mainly by comparator, pulling force sensor and relay form, wherein pulling force sensor is embedded among stationary rope, be connected with relay with comparator successively by wire, this rope pull monitoring device is by external 5V DC power supply, the upper end of described rescue rope is connected with winch, lower end is fixedly connected with fixing safety strap, the bottom of this rescue rope is installed with coupling link, the other end of coupling link is enclosed within on stationary rope and along stationary rope and slides up and down.
The present invention has following beneficial effect: when rescue at sea, be not subject to the impact of marine stormy waves, can locate fast and will fix safety strap and deliver to personnel to be rescued place, and due to the position-limiting action of coupling link and stationary rope, make to rescue rope more stable, avoid rescue process affected by sea wind and wantonly swung, having increased rescue safety factor, having improved rescue efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention, and Fig. 2 is the schematic circuit diagram of rope pull monitoring device of the present invention.
Drawing explanation: 1, winch, 2, projector, 3, stationary rope, 4, magnetic force positioning seat, 5, rescue rope, 6, fixing safety strap, 7, coupling link, 8, rope pull monitoring device, 9, helicopter base plate.
Detailed description of the invention
Describe by reference to the accompanying drawings embodiment in detail.A kind of helicopter rescue at sea auxiliary device, comprise winch 1, projector 2, stationary rope 3, magnetic force positioning seat 4, rescue rope 5, fixing safety strap 6, coupling link 7 and rope pull monitoring device 8, wherein winch 1 and projector 2 are fixed on helicopter base plate 9, described stationary rope 3 has weak elasticity, its upper end is connected with projector 2, lower end is connected with magnetic force positioning seat 4, the radius of this magnetic force positioning seat 4 is 15-20cm, tension magnetic force is 1500-2000kg, electromagnetic module is equipped with in its inside, by switch control current lead-through, the control path of magnetic force positioning seat 4 is arranged at stationary rope 3 inside and is connected with the power supply of helicopter, after energising, magnetic force positioning seat 4 produces magnetic force, closing switch power-off magnetic force disappears, described projector 2 is for launching stationary rope 3, also can rolling stationary rope 3, when transmitting stationary rope 3, first open the switch of magnetic force positioning seat 4, when rolling stationary rope 3, first close the switch of magnetic force positioning seat 4,
Described rope pull monitoring device 8 is arranged at the bottom of stationary rope 3, mainly by comparator, pulling force sensor and relay form, wherein pulling force sensor is embedded among stationary rope 3, be connected with relay with comparator successively by wire, this rope pull monitoring device 8 is by external 5V DC power supply, when stationary rope 3 is subject to large wind impact, when pulling force exceedes max-thresholds, this rope pull monitoring device 8 cuts off magnetic force positioning seat 4 switches automatically, ensure that the as far as possible little helicopter in hover that affects manipulates, its principle of work is: utilize comparator, set threshold voltage, by comparator output low and high level, controlling aerotron conducting turn-offs, drive relay adhesive to disconnect, first, pulling force sensor reduces gradually along with pulling force increases resistance, when initial, comparator output terminal output low level, relay is in attracting state, magnetic force positioning seat 4 is normally worked, in the time that pulling force increases, pulling force sensor resistance reduces, comparator in-phase end voltage raises, reach after setting threshold, comparator output high level, relay disconnects, 4 demagnetizations of magnetic force positioning seat, quit work,
