The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
With reference to accompanying drawing, the height by support air duct 6 being arranged on the highway intermediate isolating band apart from about the 1.5-2 rice of ground is provided with blower fan 10 on ground, by vertical air duct 14 wind is sent in the main wind tube 6.There is a support tube 15 air duct 6 outsides, 15 of air duct 6 and support tubes have reinforced bar support bar and four division boards 16, by division board 16 space between air duct and the support tube is divided into four parts, wherein left and right sides two parts are for pressing wind chamber 13, the wind in the air duct through press wind intonation perfect square to after the last air outlet 12 of support tube 15 sidewalls, following air outlet 11 blow out.Wind through air outlet 11 formation down is that level is isolated wind band 8, and its effect is the interference wind that vehicle traveling process forms to be isolated with the wind band on top keep apart.The wind band that is formed by last air outlet 12 is main force's wind band 7, and the effect of this main force's wind band is that the snow with overhead about two meters of road surface blows to the both sides, road surface.Prevent that it from falling in the track.
Shown in Figure 1, the isolation strip blower fan is arranged on the isolation strip 4, and there are fast 1, runway 2 and maintenance track 3 in both sides, and main force's wind band 7 can not fall into the snowflake 9 in the sky, the track track of blowing off in fast and the runway at least.Electronic caution board 5 is used for that alerting drivers is careful to travel.
Shown in Figure 2, along the air duct trend cascade blower fan is set, general every 8-10 kilometer is provided with a blower fan.
The setting of blower fan and type selecting are undertaken by following step: 1, calculate and determine required ventilation in the pipeline; 2, calculate required gross thrust It:It=△ P * At (N); Wherein, At: pipeline cross-sectional area (m2); △ P: every resistance sum (Pa); Generally should take into account following 4: 1) pipeline air intake resistance and air outlet resistance; 2) pipeline skin friction resistance, the resistance that suspention blower fan apparatus, support and road sign etc. cause; 3) traffic resistance; 4) Yin Wendu, air pressure between pipeline is imported and exported, wind speed is different and the resistance that pressure differential produced of giving birth to. and 3, determine the overall plan that blower fan is arranged.Provide the scope of thrust according to pipeline length, required gross thrust and jet blower, tentatively determine on the pipeline length overall, to arrange altogether m group blower fan, every group of n platform, the thrust of every typhoon machine is T.
Satisfy the gross thrust requirement of m * n * T 〉=Tt, consider following restrictive condition simultaneously: when 1) n typhoon machine was arranged side by side, its center line horizontal spacing should be greater than 2 times of blower fan diameters; When 2) m organized (platform) blower fan tandem, longitudinal pitch should be greater than 10 times of pipeline diameters; 4, determining of separate unit fan parameter: the performance of jet blower is weighed with the thrust that it puts on air-flow, the thrust that blower fan produces equals the momentum poor (momentum equals the product of flow quality flow and flow velocity) that blower fan is imported and exported air-flow in theory, in the fan test condition earlier, the momentum of inlet air flow is zero, so can calculate under test condition the theoretical thrust of blower fan: theoretical thrust=p * Q * V=pQ2/A (N); P: atmospheric density (kg/m3); Q: air quantity (m3/s); A: blower fan discharge area (m2); Test-bed measurement thrust T1 is generally 0.85-1.05 times of theoretical thrust. depend on the structure of Flow Field Distribution and blower fan inside and sound absorber. and blower fan thrust data given in the fan performance parameter chart all are as the criterion with test-bed measurement thrust, but measurement thrust also is not equal to blower fan is contained in the thrust available T that can produce in the pipeline, this is the influence (Kodak's grace effect) that can be subjected to the off-load effect that air velocity produces in the pipeline when being lifted in the pipeline because of blower fan, and thrust available reduces. effect availability coefficient K1 and K2 represent and calculate: T=T1 * K1 * K2 or T1=T (K1 * K2);
T wherein: be installed in the jet blower thrust available (N) in the pipeline; T1: test-bed measures thrust (N); K1: mean air flow speed and blower fan outlet wind speed is to the influence coefficient of blower fan thrust in the pipeline; K2: the influence coefficient of blower fan axial flow distance between channel wall; The performance of jet blower is weighed with the thrust that it puts on air-flow, the thrust that blower fan produces equals the momentum poor (momentum equals the product of flow quality flow and flow velocity) that blower fan is imported and exported air-flow in theory, in the fan test condition earlier, the momentum of inlet air flow is zero, so can calculate under test condition the theoretical thrust of blower fan: theoretical thrust=p * Q * V=pQ2/A (N); P: atmospheric density (kg/m3); Q: air quantity (m3/s); A: blower fan discharge area (m2); Test-bed measurement thrust T1 is generally 0.85-1.05 times of theoretical thrust. depend on the structure of Flow Field Distribution and blower fan inside and sound absorber. and blower fan thrust data given in the fan performance parameter chart all are as the criterion with test-bed measurement thrust, but measurement thrust also is not equal to blower fan and is contained in the thrust available T that can produce in the tunnel, this is the influence (Kodak's grace effect) that can be subjected to the off-load effect that air velocity produces in the tunnel when being lifted in the tunnel because of blower fan, and thrust available reduces. effect availability coefficient K1 and K2 represent and calculate: T=T1 * K1 * K2 or T1=T (K1 * K2); T wherein: be installed in the jet blower thrust available (N) in the tunnel; T1: test-bed measures thrust (N); K1: mean air flow speed and blower fan outlet wind speed is to the influence coefficient of blower fan thrust in the tunnel;
K2: the influence coefficient of blower fan axial flow distance between tunnel wall.
Shown in Figure 3, between air duct 6 and the support tube 15 by four division boards 16, be divided into four parts, wherein two parts are static chamber up and down, the left and right sides is two and presses wind chamber 13, in pressing the wind chamber wind deflector is arranged, wherein descending air outlet 11 1 sides is horizontal wind deflector 18, the oblique wind deflector 17 of last air outlet 12 1 sides.Wind in the air duct 6 enters through wind hole 19 presses wind chamber 13, and top goes out with oblique wind under the wind deflector effect, and the bottom then goes out with horizontal wind.Form isolation wind band 8 and main force's wind band 7 respectively on top, track.
In the last air outlet 12 that Figure 4 shows that the support tube sidewall and the following air outlet 11.
Shown in Figure 5, the wind hole 19 of air duct 6 sidewalls.
