Description

Window breaking bullet

Technical Field

The utility model belongs to the technical field of fire-fighting equipment's technique and specifically relates to a broken window bullet is related to.

Background

Along with the rapid development of economic infrastructure in China, the heights and the densities of high-rise buildings in large and medium cities are continuously increased, and the fire safety problem of the high-rise buildings is increasingly highlighted. Once a fire disaster happens to a high-rise building, the consequences can not be imagined. The fire fighting of high-rise buildings is a serious test in the development process of various cities, and the development of an effective high-rise fire fighting system are urgent.

Currently, an unmanned aerial vehicle is used for fire fighting, has the advantages of fast response, no restriction of high-rise and narrow space, and effective prevention of fire fighters from casualties, and is an effective means for fire fighting outside high-rise buildings; when the unmanned aerial vehicle is used for fire fighting, the window area of a high-rise building is small, the unmanned aerial vehicle can not be accommodated, and the fire fighting rescue efficiency of the unmanned aerial vehicle is seriously influenced; just need a instrument this moment, with high-rise building's window breakage, the unmanned aerial vehicle of being convenient for has sufficient space to carry out fire control work to building inside.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem among the prior art, the utility model provides a broken window bullet to the problem that the glass of solving high-rise building hinders unmanned aerial vehicle to the inside fire control of building.

The technical scheme of the utility model is that:

the utility model provides a broken window bullet, includes columniform bullet head main part, and the one end of bullet head main part is fixed with broken portion, and the other end of bullet head main part rotates and is connected with a plurality of evenly distributed's fin, and it has a plurality of recesses that are on a parallel with bullet head main part axis to open in the bullet head main part, and the recess is used for accomodating the fin, all be fixed with the spring in the recess.

Furthermore, the crushing part is hemispherical, and the arc end surface of the crushing part is passivated.

The arc end surface of the crushing part is passivated into a plane, so that the stress of the glass is uniform during the collision, and the glass is easier to crush.

Furthermore, an anti-skid ring is fixed at the joint of the crushing part and the bullet head main body.

An anti-skid ring is fixed at the joint of the crushing part and the bullet head main body, so that the friction force between the bullet head main body and the inner wall of the launching device is further increased, and an anti-skid effect is achieved.

Furthermore, the free end of the empennage is of a circular arc structure.

The free end of the tail wing is arranged to be of a circular arc structure, so that the air resistance of the tail wing in the flying process is reduced, and the functional loss of the window breaking bullet in the flying process is reduced.

Furthermore, the empennage is rotatably connected in the groove through a bolt.

The empennage is connected with the bullet head main body through bolts, so that the installation is simple and convenient; meanwhile, the tail wing can be quickly replaced after being damaged, and the round use of the window breaking bullet is realized.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in this scheme, unmanned aerial vehicle will break the window bullet and spray away, utilizes the broken portion striking glass of breaking the window bullet, makes glass broken, opens the passageway that unmanned aerial vehicle got into the building.

2. In this scheme, broken portion is behind striking glass, and after bullet head main part punctured glass, the fin takes place the secondary striking with glass, with glass breakage, avoids appearing glass and breaks and does not have the condition of garrulous falling.

3. In this scheme, set up fin and bullet head main part into to rotate and be connected, not thrown away under the condition of broken window bullet head, fold up the fin in the recess, can practice thrift the space, further improve unmanned aerial vehicle's load.

4. In the scheme, when the window breaking warhead is loaded in the launching device of the unmanned aerial vehicle, the tail wing is folded in the groove and is pressed against the inner wall of the launching device under the action of the spring, so that the anti-skidding effect can be achieved, and the window breaking warhead is prevented from sliding out of the launching device when the unmanned aerial vehicle flies; meanwhile, after the window breaking bullet head falls off the launching device, the acting force applied by the spring pushes the tail wing to unfold, so that the tail wing can be in contact with the glass, and the effect of breaking the glass is achieved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

The utility model discloses a reference numeral in the description drawing includes: bullet head main part 1, broken portion 2, fin 3, recess 4, spring 5, anti-skidding rubber ring 6, bolt 7.

Examples

Substantially as shown in figure 1: the window breaking bullet comprises a cylindrical bullet main body 1, wherein a breaking part 2 is integrally formed at the left end of the bullet main body 1, the breaking part 2 is hemispherical, the arc end surface of the left end of the breaking part 2 is passivated, and an anti-skid rubber ring 6 is bonded at the joint of the breaking part 2 and the bullet main body 1; the right end of the bullet head main body 1 is rotatably connected with three tail wings 3, and the tail wings 3 are uniformly distributed around the central axis of the bullet head main body 1; the free end of the tail wing 3 is of an arc-shaped structure; the surface of bullet head main part 1 is opened has three recess 4 that is on a parallel with bullet head main part 1 axis, and recess 4 is used for accomodating fin 3, and fin 3 connects to rotate through bolt 7 and connects in recess 4, still is fixed with spring 5 in the recess 4, and the one end welding of spring 5 is on the recess 4 inner wall, and the other end of spring 5 is used for supporting fin 3.

The specific implementation process is as follows:

the fire fighter will break the right-hand member of window bullet towards unmanned aerial vehicle emitter to in will breaking the window bullet and pushing emitter, emitter's inner wall exerts the effort to fin 3, makes fin 3 to the swing of 4 directions on the recess, accomodate to recess 4 until fin 3 in, avoid fin 3 to crowd the loading space who accounts for unmanned aerial vehicle.

When fin 3 accomodates in recess 4, fin 3 compression spring 5, spring 5 applys thrust to fin 3, makes fin 3 and emitter's inner wall paste tightly, and the frictional force between increase fin 3 and the emitter plays skid-proof effect, when preventing that unmanned aerial vehicle from flying, broken window bullet roll-off emitter.

When the launching device launches the window breaking bullet, the tail 3 reversely swings to separate from the groove 4 under the action of the spring 5, so that the tail 3 is completely unfolded.

When the window breaking bullet impacts on the glass, the breaking part 2 firstly collides with the glass for the first time to break the glass, and meanwhile, the breaking part 2 and the bullet main body 1 penetrate through the glass from the collision part; when the window breaking bullet penetrates through the glass, the tail wing 3 is in contact with the glass, secondary collision occurs, and the broken glass is impacted by the tail wing 3, so that the glass can be broken in a large area, and the situation that the glass is broken and is not broken is avoided.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
