Description

The proposed utility model relates to devices for protecting various objects from mechanical and thermal extremes in various fields of technology, but primarily in aviation and space technology, where it can be used to protect the flight information recorders of space and aircraft. This utility model relates, first of all, to the design of the hulls of the so-called black boxes of aircraft, withstand high mechanical loads and thermal effects in case of fire, resulting in an accident

Containers for data recovery machines that are resistant to high mechanical stresses, including and shocks, high thermal effects resulting from a fire. Such containers are made of layers of steel, tin bronze and external soft metal, however, they have a large weight RF patent No. 2131828, MKI B 64D 1/14. The closest in technical essence to the proposed housing is a device housing for protecting memory circuits of a data logger, consisting of external and internal containers. In the cavity located in the inner container, the protected object is placed, in this cohack case - electronic memory circuits of the data logger US patent dated 01.13.1998 No. 5708565 - prototype.

The prototype uses an external container in the interior of the titanium wall with a large thickness and, accordingly, with a large weight, which is a design disadvantage. In addition, the heat accumulated by the thick drains of the external container fills the thermal effect on the protected object after the fire, which can lead to non-alphabeticality of the protected object.

increased resistance to mechanical and mechanical properties, increased static strength and increased heat-shielding efficiency in fire conditions, and, at the same time, relatively low weight and gabzhzhgi.

This problem is solved by the use of appropriate materials for the manufacture of external and internal containers and for the manufacture of a shaped container.

The body of the device for protection against: extreme mechanical and thermal influences of technical, biological and other objects requiring protection (Fig. 1) contains an external container 1, which is made of impact-resistant material. The specific characteristics of the material of the adhering container are selected taking into account the specified values of the extreme mechanical stresses and the maximum ambient temperature that the pickup must withstand. , from which the outer container is made, must have a melting point below a given maximum possible extreme temperature of thermal influence on Cortus

. If the maximum temperature O1 of the ambient medium is set during an accident of 1100 ° C, then

the melting temperature of the outer container should be selected1 {and below the temperature of 1100 C. In the preferred embodiment of the utility model, the outer container 1 is made of high-strength aluminum alloy (naphthimer, type D16, B95, B96, etc.), with a melting point of 500-660 this limit tensile strength Ov 500 MPA and yield strength gfi tensile Sto2 450 MPA. The thickness of the walls of the outer container 1 under such conditions can be 8-15 mm.

The inner container 2 is made of impact resistant material.

The specific characteristics of the material of the inner container are selected taking into account the specified values of extreme mechanical stresses and the maximum ambient temperature that the housing must withstand. The material from which the inner container is filled must have a melting temperature higher than a given maximum possible extreme temperature of thermal effects on the body. If a maximum ambient temperature of 1phi is set at 1100 ° C, then the melting temperature of the inner container must be selected above 1 lOO С. In the preferred embodiment of the utility model, the inner container 2 (at a given and specified maximum temperature) is made, for example, of steel or fabric . The thickness of the inner container may be 1-5 mm.

The inner container 2 has a shallow cavity 3 in which the protected object 4 is located. For example, these may be memory circuits of the data logger enclosed in a shell.

The body of the device for protection against extreme mechanical and thermal influences of technical, biological and other objects requiring protection (Fig. 2) may have an external forming container 5. This may be necessary if, for example, the external container 1 is covered with fireproof material 6, which can be destroyed when moving the case, random, etc. The forming body 5 is located on top of the outer container 1 and fireproof material 6 and allows convenient storage and

For the first functional coffering of the protective device case, the forming container 5 must be made of material with a melting temperature equal to or lower than the melting temperature of the material of the external container (for example, from aluminum alloys of the type D1b, V95, etc.).

(For example, the melting temperature of the forming container may be equal to or lower than 500 ° C, when the outer container is made in one of the above aluminum alloys with a melting point C).

The proposed housing may be in the form of a cylinder, cube or ball. The choice of form depends on the scale of the industrial production of the protection device, structural and technological and economic requirements. If it turns out to be economically feasible to apply various technological devices for manufacturing the device, then the shape of the ball is preferable. In the manufacture of the device in small batches, a cylinder or cube shape is preferred.

The proposed housing of the device for protection operates in its preferred embodiment as follows.
