Abstract
A mobile roadway barrier primarily for use in underground mining for protection against explosions of methane and coal dust in coal mining, which is a development of the invention described in PCT patent application PCT/ZA2005/000163. The barrier has an array of nozzles which have a deflection surface and adapters that rationalise providing a wide range of adjustment.
Description
Technical field
The invention belongs to fire and blast inhibition field, relate in particular to the mechanical device that is used in fire prevention and the antiknock device.This equipment is described in the south african patent 96/0178 of for example authorizing the applicant and PCT application PCT/ZA2005/00163.
Background technology
South african patent 96/0178 has been described the valve that is used in fire and the explosion containment device, has realized very fast, for example opens this valve in 2 or 4 milliseconds, and this is very important for handling blast effectively.When this valve was opened, the extinguishing material that for example is contained in 100 to 150bar the steel pressure vessel was released to nozzle or other dissemination apparatus.
This fire and explosion containment device are protected and other places as " tunnel " that mobile device is applied in the underground mining.This equipment must satisfy the distribution demand of firing-fighting medium with particular form in different environment, special " curtain " as firing-fighting medium.The flame front that should " curtain " burning up just as barrier is ejected into, and it is highly important that this curtain is an atresia basically.The invention provides additional, the modification or the improvement that are used to satisfy this demand.
Summary of the invention
The invention provides a kind of nozzle array, this nozzle array comprises a plurality of independent nozzles, each nozzle has hole and deflection surface, and the sensing of the described deflection surface of each nozzle and comprises at least two different angles with respect to common base or base line at angle.
Nozzle array can also comprise the nozzle that is different from described hole and deflection type, for example has " rose " types of nozzles in a plurality of holes in different angles.
Described nozzle with hole and deflection surface can be provided with one or more adapters that can be inserted between described nozzle and the described base, to improve the angle between nozzle deflection device surface and the described base.The surface that is tilted in relation to each other that each deflection utensil has the passage that passes this deflection device and is used to be connected respectively to described nozzle and base presents " wedge shape " outward appearance.

The specific embodiment
Shown in Fig. 1 to 5, nozzle array comprises a plurality of independent nozzle that is positioned at position 1,2,3 and 4, each nozzle has hole 5 and deflection surface 6,7,8 and 9, the sensing of the deflection surface of each nozzle is with respect to 10 one-tenth unique angles of common base, and comprise at least two different angles, in this example, comprise four different angles.Nozzle bore is usually as shown in the figure by rubber stopper 11 sealings that are positioned at nozzle body, and when the protection gas very high pressure under or curtain formation gas were applied to this nozzle, this rubber stopper was blown.
As shown in Figure 3, especially, nozzle location 1 is provided by single integrally formed unit 12, and nozzle location 2 is formed by the unit 12 with adapter 13, and adapter 13 is inserted between unit 12 and the base.This adapter has the passage 14 that passes this adapter and lead to nozzle bore, has to improve " as the chock " effect with respect to the angle of described base of deflection device surface.Similarly, nozzle location 3 is formed by the nozzle 12 with another adapter 14, and adapter 14 is inserted between described nozzle and the described base.In addition, last nozzle location 4 has nozzle 12, wherein is inserted with adapter 13 and 14.
Figure 4 and 5 illustrate in greater detail nozzle 12 and rubber stopper 11.
Fig. 6 and 7 shows another kind of nozzle array, comprise three as shown in Figures 1 to 3 type nozzle and add the nozzle 15 of their " rose ".This nozzle has cup-shaped member 16, and cup-shaped member 16 has the hole 17 to 21 that is arranged on wherein, and hole 17 to 21 has continuous angle, and on three axles 22 to 24, as shown in Figure 8.
Figure 10 and 11 shows the nozzle array 25 of expansion, constitutes the star shown in being arranged in by the nozzle sets of kind shown in six Fig. 1 to 3.Described nozzle is orientated and makes the extinguishing material that outwards sprays from described array become a face.
Figure 12 and 13 shows similar nozzle array 26, but is made of the nozzle sets of kind shown in Fig. 6 and 7, wherein in each nozzle sets, has the nozzle of three deflection types and the nozzle of a rose type.
Figure 14 and 15 shows the array 27 that is installed on the mobile platform 28, can also see that two detections are near the flame front of fire or the photoelectron detector 29 of blast, and holding the fire-suppressant gas under the unusual high pressure or the cylinder 30 of powder, control valve 31 is positioned at described cylindrical below.Described nozzle array is installed on the panel 32 on the bar 33, and bar 33 is installed in the top and the bottom of pin, and it can be rotated, to determine the angle of described array obliquely, as shown in figure 16.
