Abstract

The utility model discloses a wind power wind blower, comprising a suction duct, on top of which is connected with a three-way duct, one end of which is connected with a horn-shaped wind inlet tube and the other end of which is connected with a guide wing. The model utility realizes the purpose of blowing natural wind and exchanging air, without electric power, with energy conservation. The structure of the utility model is simple, with low cost, easy maintenance, long service life and low production cost. It can be widely applied to discharging smoke off cookstoves for urban and rural residents living and heating, pumping fumes from the family kitchens, discharging smoke off chimney, exhausting off public toilets and ventilation, etc.and can also be used for places contaminated by gas and dust, such as rice and flour processing factories and laboratories. Large wind power wind blowers can also be used for mine ventilation, industrial boilers or civilian boiler blowing, the basement ventilation, particularly for the places in the absence of power supply, such as blowing and ventilation in field yurts, with wide market prospects.

Description

Draught fan by wind force

Affiliated technical field

The utility model relates to a kind of induced draught fan, relates to a kind of draught fan by wind force that utilizes natural wind to do power specifically.

Background technique

In daily life and production environment, usually use induced draught fan, as range hood, ventilation fan, blower etc., these all are induced draught fans.The induced draught fan that uses all needs motor drives work at present, so these equipment are all wanted consumed power, because the generally use of these induced draught fans, so the electric energy of induced draught fan consumption also is very considerable.The mechanism of present employed induced draught fan is relative complex also, and cost is higher relatively, and general induced draught fan can only adapt to a kind of application mode, and can't reach multi-purpose exchange and use, bad adaptability, user cost is higher.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of gravity force and wind induced draught fan, and this machine is simple in structure, and is with low cost, and usability is reliable, and blower effect is good, not power consumption, and user cost is low.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of draught fan by wind force comprises suction pipe, and its structure outline is: said suction pipe upper end connects three-way pipe, and an end of this three-way pipe connects tubaeform air intake tube, and the other end of this three-way pipe connects guide vane.The utility model horizontal position is a three-way pipe, the intermediate throughholes of this three-way pipe connects suction pipe, and the front end of horizontal three-way pipe is made flue air intake tube, and tail end is a guide vane, so just can make intake grill always towards the direction of the wind comes from, after wind was blown into from intake grill, because the caliber of tubaeform air intake tube diminishes gradually, gas flow rate increased like this, pressure reduces, the gas that needs to discharge then can enter in the three-way pipe by vertically arranged suction pipe, discharges with the wind, has played the effect of air inducing exhaust.

Said suction pipe comprises fixedly suction pipe of bottom, and this fixedly connects the rotation suction pipe by universal bearing above the suction pipe.By universal bearing is installed, make the rotation suction pipe rotate very flexible.

The beneficial effects of the utility model are, this draught fan by wind force was as long as both can run well use when gentle breeze, the northern area of China is the Northwest particularly, annual wind day is a lot, 3 grades in a lot of areas can be used, as or connect use in parallel with electronic induced draught fan with windward Ri Keda more than 300 day throughout the year, can solve calm day air inducing exhausting problem, open electronic induced draught fan when both calm.The utility model has been used the air velocity in the fluid mechanics and the relation of sectional area, the relation of pressure and flow velocity, and utilized the Der Grundsatz der Maschinen of " wind vane ", utilize natural wind to realize the purpose of air inducing ventilation, so without electric energy, energy saving.The utility model is simple in structure, and is with low cost, easy to maintenance, long service life, and cost of production is low.Can be widely used in the pot and stove smoke evacuation of living standard of urban and rural population and heating, family kitchen smoke pumping, chimney smoke evacuation, public lavatory exhaust, ventilation etc. also can be used for having the place of gas and dust pollution, such as rice and flour processing factory, the laboratory.The large scale wind induced draught fan also can be used for mine ventilation, industrial boiler or civil boiler air inducing, and the basement ventilation, particularly in the place that does not have power supply, the usefulness as the ventilation of open-air yurt air inducing has vast market prospect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

1. air intake tubes among the figure, 2. three-way pipe, 3. guide vane, 4. universal bearing, 5. suction pipe.

Embodiment

As shown in Figure 1, a kind of draught fan by wind force, comprise suction pipe 5, this suction pipe comprises fixedly suction pipe of bottom, and this fixedly connects the rotation suction pipe by universal bearing 4 above the suction pipe, by universal bearing is installed, it is very flexible that the rotation suction pipe is rotated, and said suction pipe upper end connects the intermediate throughholes of three-way pipe 2, and two ends one end of this three-way pipe connects tubaeform air intake tube 1, the other end connects guide vane 3, this guide vane is greater than tubaeform air intake tube, thereby plays the effect of guiding with the wind.

Claims

1, a kind of draught fan by wind force comprises suction pipe (5), it is characterized in that: said suction pipe upper end connects three-way pipe (2), and an end of this three-way pipe connects tubaeform air intake tube (1), and the other end of this three-way pipe connects guide vane (3).

2, draught fan by wind force according to claim 1 is characterized in that: said suction pipe comprises fixedly suction pipe of bottom, and this fixedly connects the rotation suction pipe by universal bearing (4) above the suction pipe.
