Description
Technical field
The invention belongs to wind fire-extinguisher technical fields, refer in particular to a kind of Novel wind spray.
Background technology
The fire fire behavior on forest or grassland can occur often, and in face of the fire fire behavior of generation, best processing mode is just
To be put out by water with water, for forest or grassland, occur fire either fire behavior when, periphery without or cannot and
When get sufficient water source, can only put out a fire by tool or wind fire-extinguisher, existing common wind fire-extinguisher its
Duct set inner wall is smooth, and shape is in cone barrel, and big end connects exhaust apparatus, although this kind of common wind fire-extinguisher energy
Enough play the role of certain fire extinguishing, but its shortcoming is also obvious, exhaust apparatus is compressed to by air in duct set,
Pressure-air may result in the pressure-air of exhaust apparatus generation in this way by can mutually be collided during the duct set of cone barrel
Pressure Express weakness, it is nearer from the air distance ejected of small end, disperse very much, and wind in pipe by multiple scattering and
Reflection, be easy to cause downdraught, influences wind-force output, in order to ensure the efficiency of fire extinguishing, can only increase the output work of exhaust apparatus
Rate, energy consumption are big.
Invention content
The object of the present invention is to provide it is a kind of with spiral stream guidance slot, injection air concentrate, jet length it is remote, the energy disappears
Consume balanced Novel wind fire extinguisher.
The object of the present invention is achieved like this：
A kind of Novel wind spray, including spray main body, the spray main body includes exhaust apparatus and duct set,
The duct set includes connection guide part and air-flow increase portion, one end connection exhaust apparatus of the connecting portion, and the other end connects
Air-flow increase portion is met, spiral stream guidance road at least one is formed in the air-flow increase portion, the one end in the spiral stream guidance road connects
Guide part is connect, the other end passes through the end face in air-flow increase portion to be connected with outside.
In a kind of above-mentioned Novel wind spray, the air-flow increase portion is oval tubular.
In a kind of above-mentioned Novel wind spray, the connecting portion be cone barrel, the busbar and gas of the connecting portion
The busbar institute for flowing increase portion is angled between 160 ° -190 °.
In a kind of above-mentioned Novel wind spray, the length in the air-flow increase portion is longer than the length of connecting portion.
In a kind of above-mentioned Novel wind spray, the length of the connecting portion accounts for the 10%-30% of duct set overall length
Between.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：
The duct set inner wall of the present invention is designed with a plurality of spiral stream guidance slot, for pressure-air to be guided to do spiral shell in duct set
Centrifugal movement is revolved, the pressure differential at the center pressure and tube wall of duct set can be allowed to increase, more toward at the air outlet slit of duct set,
The radial pressure of generation is bigger, and the spiral centrifugal distortion of pressure-air is more apparent, with high speed, pressure-air continuation forward,
When leaving duct set, pressure-air can drive the air outside duct set to continue to rotate, and can achieve the effect that collect wind.This hair
It is bright at work, exhaust apparatus compression air when passing through duct set, air pressure attenuation it is slack-off, the power of exhaust apparatus is not
It needs to improve, which reduces the consumption of the energy.

Specific embodiment
With reference to specific embodiment, the invention will be further described：
Embodiment one, as shown in Figs. 1-3, a kind of Novel wind spray, including spray main body, the spray main body
Including exhaust apparatus 10 and duct set 1, the duct set 1 includes connection guide part 11 and air-flow increase portion 12, the connecting portion
11 one end connection exhaust apparatus 10, the other end connect air-flow increase portion 12, are evenly equipped at two in the air-flow increase portion 12
Spiral stream guidance road 13, one end connection guide part 11 in the spiral stream guidance road 13, the other end pass through the end in air-flow increase portion 12
Face is connected with outside, and the air-flow increase portion 12 is oval tubular, and said program is in order to which the air that exhaust apparatus compresses is logical
When crossing duct set, air pressure attenuation is slack-off, and the width and depth in the spiral stream guidance road 13 of design are the thickness according to duct set 1
Degree changes and changes, and the ratio between the width in spiral stream guidance road and the thickness of duct set are 2：5, the depth and duct set in spiral stream guidance road
The ratio between thickness be 3：5.
In a kind of above-mentioned Novel wind spray, the connecting portion 11 be cone barrel, the busbar X of the connecting portion 11
Angled between 160 ° -190 ° with the busbar Y institutes in air-flow increase portion 12, said program is in order to which air can be concentrated, and is gone out
The air of wind apparatus compression can allow air pressure attenuation slack-off so that the air distance of injection lengthens when passing through duct set.
In a kind of above-mentioned Novel wind spray, the length in the air-flow increase portion 12 is longer than the length of connecting portion 11
Degree, said program are to be able to the distance and pressure for allowing pressure-air that can enhance its injection when passing through duct set.
In a kind of above-mentioned Novel wind spray, the length H of the connecting portion 11 accounts for the 10%- of 1 overall length I of duct set
Between 30%, said program is the distance and pressure sprayed for the pressure-air further increased through duct set.
Embodiment two, as shown in figure 4, embodiment two and embodiment one are essentially identical, difference is embodiment one
Spiral stream guidance road is at two, and the spiral stream guidance road of embodiment two is at three.
Embodiment three, as shown in figure 5, embodiment three and embodiment one are essentially identical, difference is embodiment one
Spiral stream guidance road is at two, and the spiral stream guidance road of embodiment three is everywhere.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
