RU65767U1 - PROTECTIVE SCREEN OF THE FIRE LAPTEN BARREL (OPTIONS) - Google Patents

Abstract

The utility model relates to fire extinguishing devices, namely, to controlled fire monitors and serves as a firefighter protection from the effects of radiation and thermal radiation of the fire source during the fire.

Description

The utility model relates to fire extinguishing devices, namely to controlled fire monitors (monitors), which serve to create a directing jet of extinguishing agent.

The objective of the utility model is to create a device that protects the firefighter from radiation and thermal effects of an open flame in the process of extinguishing and extinguishing a fire, especially for stationary fire monitors.

Known fire trucks of the type AC-40 (131), equipped with fire monitors LS-S-40, without protective shields. Firefighters with fire monitors are also known, they also lack protective shields. Known fire monitors installed permanently in production facilities (for example, at a state district power station-2 in Surgut, Tyumen region), which also lack protective shields. No analogues of the proposed utility model from the prior art have been identified.

The essence of the utility model is that a rectangular fire shield is put on the fire carriage barrel in plan, which impedes and reflects the radiation-thermal effect of the flame on the fireman.

Figure 1 presents a drawing of a protective screen. Overall dimensions (L1, L2, H) and landing size d are determined specifically for each type of monitor. So, for a fire monitors trunk type LS-S-40, L1 = 1400 mm, N = 1500 mm, d = 120 mm.

The protective screen is made of two sheets of metal 1 and 3 and the space between which is filled with heat-insulating material 2 having high fire resistance (for example, asbestos cloth), and has a hole 5 for putting on the monitor barrel. The protective screen is bent in such a way that it has a frontal I (facing the flame) and side II planes that have a fire-resistant coating and are able to reflect the radiation-thermal effect of the flame in any way (for example, coated with zinc, glazed with ceramic composition or polished,

etc.). For the convenience of controlling the guiding jet of the extinguishing agent by the fire monitor, the inspection window 4 has a rectangular viewing window 4 with heat-resistant glass having a heat-reflecting effect.

Figure 2 presents a drawing of a protective screen mounted on the monitor. The protective shield 6 is attached to the monitor barrel 7 using metal rods 8, one end of which is fixed to the monitor and the other to the plane of the protective shield.

When controlling the fire monitor with handles 10, the protective screen 6 moves together with the barrel 7 in vertical and horizontal planes, protecting the firefighter from radiation and thermal effects of an open flame, and the presence of the viewing window 4 allows you to accurately direct the stream of extinguishing agent to the right place.

The monitor itself is located and mounted on a fixed base 11.

The protective screen can be mounted both to the monitor barrel 7 (Fig. 2) in this case, it moves together with the barrel 7, and to the fixed base 11 (Fig. 2), in this case the monitor barrel rotates in a conical hole 5 (Fig. 3) the fire screen of the fire monitor.

Feasibility or other efficiency.

1. The risk of burns to the fireman is significantly reduced, and favorable working conditions are created.

2. The time spent by the firefighter in the high temperature zone is increasing.

Claims (8)

1. The protective screen of the fire monitor, containing two rectangular metal sheets resistant to temperature, between which is a heat-insulating material with a high degree of fire resistance, for example, an asbestos cloth, and curved in such a way that it has frontal and lateral planes, characterized in that mounted on a fire monitor through a through hole in the screen, and attached rigidly to the carriage in various ways, for example, using rods, and is configured to move jointly stno with fire monitors. 2. The fire monitor screen according to claim 1, characterized in that the surface of the screen facing the flame has the ability to reflect the radiation-thermal effect of the flame by any of the methods, for example, coated with zinc, polished. 3. The fire monitors barrel screen according to claim 1, characterized in that in the upper part there is a through inspection hole of a rectangular shape for controlling a stream of extinguishing agent. 4. The fire monitor screen according to claim 1, characterized in that a heat-resistant glass with a high heat-reflecting effect is mounted in the inspection window. 5. The fire screen of the fire monitor, containing two rectangular metal sheets resistant to temperature, between which is a heat-insulating material with a high degree of fire resistance, for example, an asbestos sheet, and curved in such a way that it has frontal and lateral planes characterized in that it is installed on a fire monitor through a through hole in the screen, is attached rigidly to the base on which the fire monitor is located with the ability to move this fire monitors in the vertical and horizontal planes through a through conical hole in the screen. 6. The fire monitor screen according to claim 1, characterized in that the surface of the screen facing the flame has the ability to reflect the radiation-thermal effect of the flame by any of the methods, for example, coated with zinc, polished. 7. The fire monitors barrel screen according to claim 1, characterized in that in the upper part there is a through inspection hole of a rectangular shape for controlling a stream of extinguishing agent. 8. The fire monitor screen according to claim 1, characterized in that a heat-resistant glass with a high heat-reflecting effect is mounted in the inspection window.
