CZ2015557A3 - A modular element of a universal barrier with ballistic resistance - Google Patents

Abstract

The modular element of the universal ballistic resistance barrier consists of rigid boards connected by bags, which can be gradually filled with water, eventually with air and other substances. The barrier is intended for both operative and long-term protection against the danger of explosion. The basic modular element consists of at least two boards that are of a composite character with ballistic resistance. By filling the bags, the plates are spaced and pointed at an angle. The volume and weight of the impregnated substance, usually water, forms a barrier to absorb pressure waves and fragments. Shards are trapped or eventually directed by fragments. The interconnection of the modular elements and their chaining creates a complete barrier.

Description

Modular element of universal barrier with ballistic resistance

Technology:

Protective equipment, military equipment

BACKGROUND OF THE INVENTION At present, the most widespread type of explosion barrier is NEW YERSEY concrete road barriers. It is an effective barrier, but its disadvantage is heavy handling, storage requirements and therefore considerably inoperative use.

Pyrotechnic service and other components of the rescue system use different types of shields and protections. In the event of an explosion, these protections provide ballistic protection, but do not guarantee pressure wave protection.

Summary of the Invention:

The principle of the universal barrier is the use of a combination of complementary structural elements (ballistic resistant boards and bags filled with water or air), which can be used to change and improve the individual required properties of the element as a whole, suitable for the situation.

Each individually consists of two types of basic structural parts. The first are solid composite panels with ballistic resistance, which are separated by second components rubber-textile bags with the ability to fill with gases or liquids - usually air or water.

The rigid ballistic-resistant boards are joined together on the sides and the bags are interposed therebetween. By increasing the number of ballistic resistant boards, overall ballistic resistance increases significantly. By filling the bags (by filling with air, water), these plates change the angle between each other, making it difficult to pass the bullet or shrapnel again. The passage of projectiles or fragments is further complicated by the passage of other materials - a liquid that changes their ballistic curve and kinetic properties. By loading the module with liquid - eg water, the weight increases and the whole element thus obtains a pressure wave resistance. The shockwave resistance is further increased by adjusting the impact plate at an angle that deflects the pressure wave and loads the module further. The variable properties are: - weight - when filling the volume of the base element with liquid - eg the total weight changes with water. The block is heavy, resistant to external forces - such as a pressure wave. When filling with gas, such as air, the weight changes - a block, floats. - degree of ballistic resistance - Changing the mutual angles of ballistic resistant boards changes the overall ballistic resistance, the more distant the angle of the initial 90 °, the more durable the element. In the case of the passage of the shrapnel through the first layer of ballistic-resistant board, its energy is absorbed in the liquid impregnated in the bag. - degree of fire resistance - The composite materials used in themselves have high fire resistance. Filling the rubber-textile bags with liquid - water, whose properties can be further chemically modified, such as fire-resistant foaming agents, changes - increases the overall fire resistance of the module.

One module can be used as required, either alone or in a system with other modules in one or more rows in a built-in barrier corresponding to the current situation.

Drawing clarification:

Figure A) represents a basic modular element of the barrier composed of ballistic resistant boards and a bag of rubber-textile.

Figure B) Shows the sequential activation of a modular element composed of three plates (a, b, c) and two bags (1,2). The more the bags are filled, the greater the resistance of the element.

Figure C) Shows the maximum mobility of one element. EXAMPLES In the case of equipment of IRS components with modular elements of a universal barrier with ballistic resistance, it will be possible to react in a matter of minutes to the dangers of bait systems or explosion when handling hazardous materials, etc. by shielding the most destructive consequences and thereby protecting the interfering components and property.

In addition to clearing the space, intervening components can also build a barrier that will increase its durability through its gradual activation.

Industrial and other usability:

The modular element of the universal barrier with ballistic resistance has, due to its properties, the possibility of wide use from the construction industry through the components of the integrated rescue system to the components of the armed forces. It is usable wherever there is a need for fast transport and installation of individual modular elements, or in a system barrier of connected modules, which, according to the current need, we set the required properties (which can be continuously changed - increased) - shape, size, weight, etc.

Construction and civilian sphere - protection of eg line constructions for eg geotechnical building interventions such as rock remediation, demolition work, etc. - protection of public spaces, eg from areas with risks arising from the handling of pressure vessels, etc. - possible partial replacement of NEW YERSEY road concrete barrier, - regulation of traffic and movement of persons - wide range of secondary utilization possibilities due to shape and physical properties

IRS - fast installable fire barrier during fire fighting, or as a prevention against further spreading, eg in buildings or terrain - protection of hazardous areas such as pressure vessels, combustibles, compressor rooms, etc. in high-risk events such as fires, danger of explosion or other hazardous natural events - diversion of a pressure wave - a quickly installable barrier for traffic control or coordination of crowd movement - a wide range of secondary applications from litter to transport floats
