Description
Technical Field
The invention relates to a flexible skirt, in particular to a flexible skirt capable of preventing fragment leakage, and belongs to the technical field of public safety defense equipment.
Background
In recent years, the explosive terrorist attack events in the world show an increasing trend, and cause huge damage and threats to the safety of people's lives and properties. How to more safely dispose suspected explosives discovered in public places and reduce the harm to the surrounding environment when the suspected explosives explode is one of the key points of the research in the field of public safety at present.
Portable flexible explosion-proof bucket (jar) is the novel explosion-proof equipment that appears in recent years, and it possesses very big application prospect because of the dead weight is light, protective capacities is strong and do not have additional injury. The explosion-proof equipment is different from the traditional metal alloy explosion-proof container, adopts a light composite structure and is based on a liquid and fiber composite material. When explosives explode in the portable explosion-proof barrel (tank), shock waves and fragment loads can be effectively weakened, meanwhile, the barrel body can be disintegrated, but the fragments (including liquid drops) do not have secondary killing characteristics due to low soft density. The portable flexible explosion-proof barrel (tank) has light dead weight, and the bottom of the portable flexible explosion-proof barrel (tank) adopts a hollow structure, so that explosives are transferred to the net bag at the middle height through the upper opening, the explosives on the ground can be kept still, and the flexible cover is lifted by two persons to block the explosives; i.e. the explosive placement height may be a middle height or the bottom of the barrel.
When the explosive is placed at the middle height for explosion, the fragment scattering range is large, the whole barrel body height is possibly impacted by the fragments, and the fragment group load is large. When explosives are placed at the bottom of the barrel (on the ground) for disposal, a part of lower-end fragments can directly impact the ground, no threat is generated to the surrounding environment, the acting height of the fragments is very low (only below half height of the barrel body), and the problem of waste of protective materials exists at the middle upper part of the barrel body. However, the bucket body has light self weight, and the ground reflection further enhances the strength of the shock wave, so that the pre-loaded shock wave can enable the bucket body to generate upward speed, the bucket bottom can jump off the ground or turn over upwards, and some fragments can leak out from a gap formed between the bucket bottom and the ground; when the barrel body is disassembled, a few fragments intercepted in the initial barrel body can be leaked and flown out by high-speed air waves.
Fig. 1 and 2 are schematic views of the range of the fragment action barrel body when explosives are detonated at the middle height inside the portable explosion-proof barrel/tank and the ground respectively. Obviously, when the middle height inside the barrel is detonated, the fragments can act on the whole height of the barrel body, and the problem of fragment leakage cannot occur; when ground is detonated, the fragments only act on the lower height part of the barrel body, the waste of protective materials occurs on the middle upper part of the barrel body, the barrel bottom can jump or turn upwards to generate a gap between the barrel bottom and the ground, and fragment leakage occurs.
Experiments show that when explosives are placed at the bottom of the barrel for disposal, no matter how the surface density of the barrel body protective materials is increased, and when the barrel body has a redundant protective layer and is not penetrated, a fragment trace can still be found on the barrel outside evidence target. Under this operating mode, not only can cause the waste of fragment protection material, can't effectively weaken the fragment load moreover.
Disclosure of Invention
In view of the above, the present invention provides a flexible skirt for preventing fragment leakage for a portable explosion-proof barrel/tank, which can effectively solve the problem of fragment leakage when the portable flexible explosion-proof barrel/tank is used for disposing an explosive stuck to the ground, and reduce the damage to surrounding property and personnel caused by explosion of a suspected explosive to the maximum extent.
The anti-fragment leakage flexible skirt for the portable explosion-proof barrel/tank is of a flexible blanket body structure with a hole in the center, the hole in the center is an inner ring opening, and the inner ring opening is used for being sleeved on the position of a set height of the outer circumference of the barrel/tank body of the explosion-proof barrel/tank; the size of the flexible swinging skirt ensures that when the opening of the inner ring of the flexible swinging skirt is sleeved at the set height position of the outer circumference of the barrel/tank body, the rest part of the flexible swinging skirt extends downwards and is laid on the ground around the explosion-proof barrel/tank for secondary interception of fragments.
And an elastic closing-in is arranged at the opening of the inner ring.
The broken pieces of the flexible skirt from the opening of the inner ring to the outer contour line have the same protective performance.
The flexible skirt gradually reduces in fragment protection performance from the opening of the inner ring to the outer contour line of the flexible skirt.
All parts of the flexible skirt are made of the same material, but the thickness of the flexible skirt is gradually reduced from the opening of the inner ring to the outer contour line of the flexible skirt.
The flexible skirt is formed by splicing more than two materials with different fragment protection performances, and the fragment protection performance from the opening of the inner ring to the outer contour line material of the inner ring is gradually weakened.
When ground disposal of explosives inside explosion-proof tanks/tanks is employed: sleeving the flexible swinging skirt on the explosion-proof barrel/tank through the inner ring opening, positioning the inner ring opening to a position which is 1/4-1/5 away from the ground at the height of the barrel/tank body, and paving the rest part of the flexible swinging skirt downwards on the ground around the explosion-proof barrel/tank;
when dealing with explosives with a mid-height inside the explosion-proof tank/tank: the flexible swinging skirt is sleeved on the explosion-proof barrel/tank through the inner ring opening, the inner ring opening is positioned to the opening position of the top of the explosion-proof barrel/tank, and the rest part of the flexible swinging skirt covers the outer part of the explosion-proof barrel/tank downwards to form a fragment protection layer.
When ground disposal of explosives inside a portable explosion-proof bucket/tank is employed: after the flexible swinging skirt is downwards paved on the ground around the explosion-proof barrel/tank, the minimum distance between the center point of the bottom of the flexible explosion-proof barrel and the outer contour line of the part of the flexible swinging skirt paved on the ground is 2-3 times of the radius of the bottom surface of the explosion-proof barrel/tank.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
Example 1:
the embodiment provides a flexible skirt capable of being detached, stored and matched with a flexible explosion-proof barrel/tank to be used for preventing the leakage of a broken piece. The flexible skirt anti-fragment leakage principle is as follows: the flexible (low shear modulus) protective material is initially laid on the ground, and due to inertia effect and low propagation speed of transverse shear wave, the protective material is not immediately separated from the ground wholly upwards but is unfolded upwards from inside to outside, so that a secondary barrier is formed.
For convenience of description, the following text takes the flexible explosion-proof barrel as an example.
As shown in fig. 3, the flexible skirt 3 is a blanket body made of flexible material and provided with a hole in the center, the hole in the center is an inner ring opening 2, the shape of the inner ring opening 2 is consistent with the shape of the flexible explosion-proof barrel, and the flexible skirt can be sleeved at a set position above the bottom of the barrel body of the flexible explosion-proof barrel or at the top of the barrel body; the inner ring opening 2 is provided with an elastic band to facilitate the firm positioning of the inner ring opening 2 at different positions on the barrel body. The shape of the flexible pendulum skirt outer contour line 4 is not limited, and can be square or round. The size of the flexible swinging skirt 3 ensures that when the opening 2 of the inner ring is sleeved at a set position above the bottom of the barrel body or at the top of the barrel body, the swinging skirt part close to the outer contour line 4 of the flexible swinging skirt can be paved on the ground for secondary interception of fragments. The whole skirt has equal fragment protection performance from the inner ring opening 2 to the outer contour line 4, namely the skirt is made of the same material and has the same thickness.
The flexible skirt 3 can be made of various bulletproof fiber fabrics (such as aramid fiber fabrics, glass fiber fabrics, ultra-high molecular weight polyethylene fiber fabrics and the like), other common non-bulletproof fabrics (such as nylon, terylene, polyester fibers and the like) (when the equivalent of explosives is small, the common non-bulletproof fabrics can be adopted in consideration of economic factors), or the two materials can be matched for use. The flexible skirt 3 can be directly sewn into a whole by the multi-layer fabric material, and can also be wrapped and packaged by the high-molecular soft fabric. When the anti-explosion bucket is in a non-working state, the flexible swinging skirt 3 is stored into the inner net bag of the anti-explosion bucket in a mode of overlapping for many times, and when the anti-explosion bucket is used, the flexible swinging skirt 3 is taken out and unfolded and then sleeved on the bucket body of the anti-explosion bucket through the inner ring opening 2; or adopting the following storage modes: a retaining ring is sewn at intervals along the outer contour line 4 of the flexible swing skirt, and a pull rope penetrates through the retaining ring; sleeving an opening 2 of an inner ring of the swing skirt on a set position (a position in a use state) on an explosion-proof barrel, pulling up and turning over an outer contour line 4 of the flexible swing skirt to fold towards the top of the barrel, tightening the outer contour line 4 of the flexible swing skirt through a pull rope, bolting two ends of the pull rope, and fixing the flexible swing skirt 3 on the barrel body; when the folding skirt is in work, the folding pull rope is directly unfolded, the outer contour line 4 of the flexible swinging skirt is folded downwards, and the flexible swinging skirt 3 can be rapidly unfolded and put in place.
The inner ring opening 2 of the skirt is required to be positioned smoothly and firmly at the top end of the barrel body and within the height range of 1/4-1/5 of the barrel body from the ground. For the straight barrel-shaped barrel body, the size of the opening 2 of the inner ring is adjusted and designed according to the external diameter of the barrel body; for a circular truncated cone-shaped barrel body with a small upper part and a thick lower part, the size of the opening 2 of the inner ring is adjusted and designed according to the outer diameter of the barrel body corresponding to the height position from the bottom surface 1/4-1/5.
The flexible skirt 3 has the following two use modes:
(1) when the non-moving explosive is used, the explosion-proof barrel is covered outside the explosive, and the explosive is detonated at the ground as shown in fig. 5: the flexible skirt 3 is firstly sleeved on the barrel body through the inner ring opening 2, the inner ring opening 2 is positioned to the height position away from the ground 1/4-1/5 of the barrel body, and other parts of the flexible skirt 3 are opened and freely paved on the ground. The shock wave load at the bottom of the barrel is high, and the barrel body is easy to generate serious expansion deformation; compared with the mode of directly placing the inner ring opening 2 in a sticking mode, the positioning height of the inner ring opening 2 is moved up to the height position 1/4-1/5 away from the ground, so that a strong shock wave area can be effectively avoided, and the pre-tearing failure of the inner ring opening 2 of the skirt before fragment protection is prevented; however, too high a positioning would again result in waste of skirt material, since the leakage fragment protection is mainly dependent on the portion of the skirt initially lying against the ground. As shown in fig. 6, in case of ground explosion, when the barrel bottom jumps or turns upwards, the part of the swinging skirt attached to the ground does not jump up integrally immediately due to the inertia effect, but moves upwards from the inner ring to the periphery successively, so that the gap of the barrel bottom is compensated; even if the barrel body is disassembled in the later explosion stage, the swinging skirt can be unfolded like a skirt to form a secondary barrier. Therefore, the skirt can make up for the deficiency of the barrel in intercepting leakage.
The fragment protection requirement of the flexible skirt 3 is greatly due to the jump flight at the bottom of the barrel, and the fragment protection requirement is mainly due to the structural response caused by the blast shock wave load. The change of the size of the bottom of the flexible explosion-proof barrel can change the distance between the barrel body and the center of burst, the shock wave load and the structural response degree can also change along with the change, and the number, the flying range and the speed of the leakage fragments caused by the change can also change along with the change. In short, the design size of the skirt to fit the ground (i.e., leakage fragment protection requirements) depends on the size of the flexible explosion-proof tank bottom. Mechanism analysis shows that the larger the size of the barrel bottom is, the smaller the leakage fragment protection requirement is, and the smaller the required size of the flexible skirt ground is. The minimum distance (such as L in figure 4) between the center point of the bottom of the flexible explosion-proof barrel and the outer contour line of the part of the flexible skirt attached to the ground is 2-3 times of the radius (such as d in figure 4) of the bottom of the flexible explosion-proof barrel.
(2) As shown in fig. 7, when the net bag is used for transferring explosives into the barrel body for detonation at the middle height, the flexible swinging skirt is firstly sleeved above the barrel body until the opening of the inner ring is positioned to be close to the top of the barrel body, and the other positions of the swinging skirt are opened to be freely paved downwards until the swinging skirt reaches the ground. When the explosive explodes at the middle height, the swinging skirt can form an additional fragment protective layer at the whole height of the periphery of the barrel body; the fragment protective capability of the barrel body is improved. At this moment, the size of the flexible swinging skirt only needs to be ensured to cover the barrel body along the whole height of the periphery of the barrel body.
The skirt provides different forms of targeted fragment protection enhancement for the barrel body in the above two different height processing scenarios, and also means that the fragment protection material used in the explosion-proof barrel can be thinned correspondingly. Specifically, the method comprises the following steps: when the ground is disposed, the height of the fragments acting on the barrel body is very low, and the waste of protective materials exists at a plurality of positions on the upper part of the barrel body; when the middle height is used for disposal, the fragments acting on the barrel body are almost distributed to the whole height. Therefore, after the flexible swinging skirt is used, the protective materials (particularly the middle upper part) in the barrel body can be reduced, and the fiber of the middle upper part is not wasted when the ground is treated; when the intermediate height is used, the effective interception can be ensured due to the extra protection of the skirt.
The flexible skirt 3 is a flexible explosion-proof barrel (tank) facing to protection of medium-large equivalent explosive (more than or equal to 500g TNT), and is mainly used for intercepting leakage fragments with large speed gradient, and the process is the interaction of bulletproof materials and the fragments.
Example 2:
in the embodiment, the flexible swinging skirt 3 adopts a design with variable fragment protection performance from the inner ring opening 2 to the outer contour line 4 so as to match the scattering and speed characteristics of bottom leakage fragments.
Because when the portable explosion-proof barrel is used for disposing explosives on the ground, the probability of fragment leakage is high, the structural design of the flexible skirt 3 mainly faces the working condition of disposing the explosives at the barrel bottom, and the situation that the explosives are located on the ground of the barrel bottom for detonation is considered. Based on the carried out experimental analysis, the later the fragment leakage speed is lower, the higher the barrel bottom jumps upwards or overturns at the corresponding moment, the larger the range of the flexible swinging skirt 3 which is separated from the ground under the effects of the barrel body traction and the bottom leakage shock wave is, and the farther the fragment impact position of the flexible swinging skirt 3 is from the barrel body (namely the inner ring opening 2) to be close to the outer contour line 4 of the flexible swinging skirt. The breaking load encountered by the pendulum skirt from the inner ring opening 2 to the outer contour line 4 is continuously weakened. Therefore, considering material cost saving or reduction of the self weight of the pendulum skirt, the fragment protection performance of the pendulum skirt should be matched correspondingly, namely the fragment protection performance of the pendulum skirt from the inner ring opening 2 to the outer contour line 4 is weakened continuously.
The specific implementation method can be as follows:
(1) the whole skirt is formed by laminating a plurality of layers of continuous materials with the same material, but the peripheral size of each layer or a plurality of layers is gradually increased; thereby causing the thickness of the pendulum skirt to gradually decrease from the inner ring opening 2 to the outer contour line 4. As shown in fig. 7, from the inner ring opening 2 to the outer contour line 4, four layers, respectively, a flexible skirt portion a5, a flexible skirt portion B6, a flexible skirt portion C7, and a flexible skirt portion D8 are divided, and the peripheral dimensions of the four portions are sequentially increased, thereby gradually decreasing the thickness of the skirt from the inner ring opening 2 to the outer contour line 4.
(2) The whole pendulum is formed by splicing and sewing a plurality of materials with different fragment protection performances, and the fragment protection performances of the materials from the inner ring opening 2 to the outer contour line 4 are gradually weakened.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
