Abstract

The utility model relates to a device for preventing flying birds into a jet engine. The device for preventing flying birds into a jet engine is composed of a net (2), an electric winding shaft (3), a net meridian frame supporting rod (4), a rope sling (5), and an electric winding drum (6). The electric winding shaft (3) is arranged on the front edge of the jet engine (1). The back end of the net (2) is fixed to the electric winding shaft (3). The electric winding shaft (3) can control the extension of the net (2). The rope sling (5) is arranged at the front end of the net (2). The electric winding drum (6) controls the collection and the closing of the rope sling (5) through the net meridian frame supporting rod (4). The utility model has the advantages of simple structure, low cost, and convenient operation. The problems required to be urgently solved for years for people are solved.

Description

The anti-flying bird device that sucks of jet engine

The utility model belongs to the mechanical equipment field, specifically is the anti-flying bird device that sucks of a kind of jet engine.

Existing jet engine does not prevent to suck the equipment of flying bird, causes the infringement of many lives and properties, and flying bird causes aircraft to fall loss up to tens million of dollars, personnel's injury then is unable to estimate, therefore, designing the anti-flying bird device that sucks of a kind of jet engine, is people's urgent hope.

The purpose of this utility model is exactly to provide a kind of simple in structure, low cost, the anti-flying bird device that sucks of jet engine easy to use for the public.

The purpose of this utility model realizes by following proposal.

The anti-flying bird device that sucks of jet engine of the present utility model is made up of guard (2), electronic winding up axle (3), guard warp skeleton pole (4), lasso trick (5), electric reel (6), wherein electronic winding up axle (3) is arranged on the forward position of jet engine (1), the rear end of guard (2) is fixed on the electronic winding up axle (3), electronic winding up axle (3) can be controlled the flexible of guard (2), the front end of guard (2) is provided with lasso trick (5), and electric reel (6) folds by guard warp skeleton pole (4) control lasso trick (5).

This design technology level and requirement are:

1, for preventing that the flexible sealing of jet engine front end guard from being torn by huge air-flow, takes to reinforce its outer ring, with outer ring avoiding and alleviate a little more than inner ring by the method for gas shock.

2, up to standard number matter material and reinforcement warp are taked in guard hardness aspect; The density of guard, the pumping property of not overslaugh jet engine needs;

3, rise at aircraft height should be arranged, when guard shrank and to finish, the guard top can seal sealing;

4, netted top is most advanced and sophisticated indentation with warp, so that can the protruding tip circular cone when shrinking guard, to reduce the resistance of air to guard boundling top.

Simple, the low cost, easy to use of the anti-suction of jet engine of the present utility model flying bird apparatus structure has solved the problem that people urgently wish solution for many years.

Be embodiment of the present utility model below, the utility model is not limited only to described embodiment.

Structural representation when Fig. 1 stretches out for the anti-guard that sucks the flying bird device of jet engine.

Fig. 2 prevents that for jet engine it is the working state structure scheme drawing that the guard contraction of suction flying bird device is taper shape.

Among the figure: 1, jet engine 2, guard, 3, electronic winding up axle, 4, guard warp skeleton pole, 5, lasso trick, 6, electric reel.

As shown in the figure: the anti-flying bird device that sucks of jet engine of the present utility model is made up of guard (2), electronic winding up axle (3), guard warp skeleton pole (4), lasso trick (5), electric reel (6), wherein electronic winding up axle (3) is arranged on the forward position of jet engine (1), the rear end of guard (2) is fixed on the electronic winding up axle (3), electronic winding up axle (3) can be controlled the flexible of guard (2), the front end of guard (2) is provided with lasso trick (5), and electric reel (6) is flexible by guard warp skeleton pole (4) control lasso trick (5).Operating sequence is: started electronic winding up axle (3) before taking off, guard is all stretched out, start electric reel (6) again, by guard warp skeleton pole (4) lasso trick (5) is drawn in, make guard be the taper shape that can prevent to suck flying bird.Guard is to be folded into cylindrical-conical by warp-wise.Treat to shrink back guard again when aircraft is increased to the spatial domain of no flying bird, to aircraft landing, stretch out guard again by designing program, suck flying bird to prevent jet engine.

Claims

1, the anti-flying bird device that sucks of jet engine, it is characterized in that forming by guard (2), electronic winding up axle (3), guard warp skeleton pole (4), lasso trick (5), electric reel (6), wherein electronic winding up axle (3) is arranged on the forward position of jet engine (1), the rear end of guard (2) is fixed on the electronic winding up axle (3), the front end of guard (2) is provided with lasso trick (5), and electric reel (6) folds by guard warp skeleton pole (4) control lasso trick (5).
