Description

Highway tunnel special fan

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of highway tunnel special fan.

Background technology

Building tunnel or after tunnel is open to traffic, because tunnel is only two and the extraneous relative airtight environment be connected, when building tunnel, excavate and produce a large amount of dust, this dust can mix in atmosphere, contaminated air, not only has influence on the normal procedure of engineering, also causes adverse influence to the health excavating workman; And after tunnel is open to traffic, owing to lacking the exchange of air with the external world, air in tunnel moves smooth and easy not, a large amount of vehicle exhausts and running car cross the dust rolled, and make the air in tunnel become muddy, air quality extreme difference, certain injury is caused to the people of process, and due to stuffy, the light in tunnel is inherently comparatively dark, and this improves the frequency that in tunnel, traffic accident occurs greatly.

Summary of the invention

There are the problems referred to above for existing technology in the utility model, proposes a kind of highway tunnel special fan, solve how to make the air in tunnel flow unobstructed, with fresh air, visibility is high.

The purpose of this utility model realizes by following technical proposal: a kind of highway tunnel special fan, it is characterized in that, comprise tubular air duct, described air duct is connected with the top of swell fixture with tunnel mutually by suspension rod, motor is fixed with by support in described air duct, the main shaft of described motor is connected with fan, the air intake of described air duct is fixed with screen pack one, grid is fixed with between described screen pack one and motor, the air outlet of described air duct is fixed with screen pack two, the top in described tunnel is fixed with water pipe, described water pipe turning rear section is connected on suspension rod, the water side of described water pipe is positioned at air duct through the sidewall of air duct, and the water side place of water pipe has fog-spray nozzle, the downward-sloping setting of the sidewall of air duct below described fog-spray nozzle.

Water pipe is fitted in the top in tunnel and arranges along suspension rod, the installation firmness of water pipe is high, the setting of screen pack one and screen pack two, large impurity can not be entered in air duct, the long service life of fan, the effect of stable air flowing is played in the existence of grid, the wind-force that fan turns is formed is stablized, wind-force is large, the air inlet of air duct is obliquely installed, the water of water clock on air duct can be flowed out along the sidewall tilted, ponding corrosion air duct can not be produced, water is flowed out in water pipe, water is dispelled by fan, blow out vaporific, with the dust bonding in air, dust is made to fall on the ground, reach air circulation, reduce dust, improve visibility, fresh air effect.

In above-mentioned highway tunnel special fan, below described fog-spray nozzle, the angle of inclination of the sidewall of air duct is between 3-5 degree.This kind of angle is arranged, and the water dropped in air duct namely can be made to flow out fast, nor change wind direction that can be excessive, keep wind-force powerful.

In above-mentioned highway tunnel special fan, the distance between the inside wall at described fog-spray nozzle and air duct top is 3-10cm.Fog-spray nozzle is near the top of air duct, and the setting of this kind of structure, makes the water spilt from fog-spray nozzle can better go out along with the wind of fan, reach the effect of best reduction dust in air.

In above-mentioned highway tunnel special fan, described screen pack one and screen pack two are all large filter opening metal filter screens.The Main Function of filter opening be prevent paper scrap, polybag enters in air duct, filter opening is comparatively large, and filter opening not easily blocks.

In above-mentioned highway tunnel special fan, the top of described suspension rod has installing plate.The existence of installing plate increases the contact area between suspension rod and tunnel top, and the increase of contact area can install several swell fixtures more, strengthens the installation firmness of air duct.

Compared with prior art, this highway tunnel special fan has the following advantages:

1, the air duct of this highway tunnel special fan is upper has fan, also water pipe is fixed with in air duct, the flow of water pipe can control, control different discharge and different motor speeds in the different time periods, namely when vehicle flowrate is larger, discharge is large, the rotating speed of fan is fast, when vehicle flowrate is less, discharge is little, rotation speed of the fan is slow, while reaching best air circulation, reducing dust, fresh air effect, also saves electric energy and water resource.

2, below this highway tunnel special fan sprayer, the sidewall slope of air duct is arranged, and the water of water clock in air duct can be discharged timely.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of this highway tunnel special fan.

In figure, 1, air duct; 2, suspension rod; 3, support; 4, motor; 5, fan; 6, screen pack one; 7, grid; 8, screen pack two; 9, water pipe; 10, fog-spray nozzle; 11, installing plate.

Detailed description of the invention

Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.

As shown in Figure 1, this highway tunnel special fan comprises air duct 1, suspension rod 2, support 3, motor 4, fan 5, screen pack 1, grid 7, screen pack 28, water pipe 9, fog-spray nozzle 10 and installing plate 11.

Air duct 1 is in tubular, and the top of air duct 1 is fixed with suspension rod 2, and the top of suspension rod 2 has installing plate 11, and installing plate 11 is connected mutually by the top of swell fixture with tunnel.Motor 4 is fixed with by support 3 in air duct 1, the main shaft of motor 4 is connected with fan 5, the main shaft of motor 4 is consistent with the axial centre of air duct 1 with the axial centre of fan 5, the air intake of air duct 1 is fixed with screen pack 1, grid 7 is fixed with between screen pack 1 and motor 4, the air outlet of air duct 1 is fixed with screen pack 28, and screen pack 1 and screen pack 28 are all large filter opening metal filter screens.The top in tunnel is fixed with water pipe 9, water pipe 9 rear section of turning is connected on suspension rod 2, the water side of water pipe 9 is positioned at air duct 1 through the sidewall of air duct 1, and the water side place of water pipe 9 has fog-spray nozzle 10, in the present embodiment, distance between the inside wall at fog-spray nozzle 10 and air duct 1 top is 5cm, and in actual production, this distance can be 3cm or 10cm.The downward-sloping setting of the sidewall of air duct 1 below fog-spray nozzle 10, in the present embodiment, the angle of this inclination is 4 degree, and in actual production, the angle of this inclination can be 3 degree or 5 degree.

During use, by the top of this assembling in tunnel, according to this tunnel discharge value at ordinary times, regulate the rotating speed of fan 5 and the flow of water pipe 9, the time period discharge large in vehicular circulation amount is large, and the rotating speed of motor 4 is fast, and namely wind-force is large, make this blower fan by the air in tunnel and extraneous air circulation, the dust content in air can better be reduced simultaneously.The time period discharge little in vehicular circulation amount is little, and the rotating speed of motor 4 is slow, and namely wind-force is less, reaches the object of saving electric power and water resource.
