Abstract
The utility model discloses a kind of self-action ventilation openings using wind energy, including top wind collecting part and leg space ventilation oral area point.Top wind collecting part drives whole device to rotate using wind energy, and during rotation, inside and outside wall forms draught head to leg space ventilation mouth, and inner air is driven to discharge.Wind energy energy supply is fully utilized in the utility model, and energy conservation and environmental protection does not rely on extraneous power supply, while internal structure is simple, and ventilation shaft effective area is larger, and drafting efficiency is high, is easily installed disassembly, convenient for cleaning.
Description
Technical field
The utility model is to be related to a kind of ventilation device, concretely relates to a kind of self-action ventilation opening.
Background technique
Existing ventilation equipment, generally power driven install revolving wormgear fan at ventilation road junction, pass through fan leaf
The rotation of piece generates internal and external pressure difference, and internal gas is driven to discharge outward.The ventilation of this method is relatively stable, but consumes electric energy, if
Power-off condition is encountered, then can terminate work, and need connection electric wire between fan and extraneous power supply, cause structure in ventilation shaft multiple
Miscellaneous, installation and removal difficulty is larger.By being used for a long time, the dust and oil in air can be accumulated in fan blade and electric wire
Dirt, cleaning are not easy.If there is one kind not by being driven by electricity, the ventilation device of simple structure can solve to a certain extent
State problem.
Summary of the invention
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of self-action ventilation using wind energy
Mouthful, make ventilation opening rotation using wind energy, internal gas is discharged under draught head, and internal structure is single, is easily installed disassembly.It can
It solves to consume energy larger to extraneous electric power dependence height in existing ventilation equipment, internal structure is complicated, installation, dismantles and clean not side
Just the problem of.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of self-action ventilation opening using wind energy, including central shaft, the top of central shaft are fixed with cross-bar, and ten
Four ends of word bar are connected a hemispherical Shell, and the openings of four hemispherical Shells is towards identical；The end of central shaft and hollow cylinder
Body is connected, several openings are offered on hollow cylinder, and hollow cylinder lower end connects ventilation shaft.
Preferably, the opening is rectangular configuration.
It is further preferred that the length direction of the rectangle is along hollow cylinder axial direction, several rectangular apertures are around sky
It uniformly arranges heart cylindrical body periphery.
Smooth engagement connects between hollow cylinder and ventilation shaft.
Preferably, the central shaft is fixed by bearing and hollow cylinder.
When blowing air over, wind will drive hemispherical Shell, the whole axis around central shaft of cross-bar and central shaft consolidation
Heart rotation.Leg space ventilation mouth portion body is a hollow cylinder, which binds, and solid with wind collecting part
Knot, lower part is penetrating, and with ventilation shaft smooth engagement.There is equally distributed opening on hollow cylinder, be discharged for internal gas,
Entire hollow cylinder and central shaft consolidate, and central shaft is connected in lower part with the spring bearing in pipeline, and guarantee is entirely set
It is standby to rotate and will not fall around the axle center of central shaft.
Compared with prior art, the utility model has the beneficial effects that
The utility model can be rotated using extraneous wind energy driving whole device, be produced using ventilation opening part high speed rotation
Raw internal and external pressure difference, internal gas is discharged, and is not necessarily to power supply power supply, energy conservation and environmental protection.Meanwhile the utility model only need to be in pipeline
Inside installation radial journal bearing, without installing fan and electric wire, so that channel interior structure is simple, ventilation shaft is effective to cross wind area
Increase, improves drafting efficiency.In addition, equipment is easily installed disassembly, convenient for cleaning.
Detailed description of the invention
Fig. 1 is top wind collecting partial schematic diagram；
Fig. 2 is leg space ventilation mouth partial schematic diagram；
Fig. 3 is the utility model overall structure diagram；
In figure: 1. hemispherical Shells, 2. cross-baves, 3. central shafts, 4. hollow cylinders, 5. openings, 6. ventilation shafts.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
A kind of self-action ventilation opening using wind energy described in the utility model, including central shaft 3, the top of central shaft
It is fixed with cross-bar 2, four ends of cross-bar are connected a hemispherical Shell 1, and the openings of four hemispherical Shells is towards identical；Central shaft
End and hollow cylinder 4 be connected, offered on hollow cylinder several opening 5, hollow cylinder lower end connection ventilation
Pipeline 6.
Central shaft is fixed by the spring bearing in pipeline, so that smooth rotation, will not fall or horizontal direction is sent out
Raw displacement.
Central shaft, cross-bar and hemispherical Shell constitute top wind collecting part.
Hollow cylinder, opening and ventilation shaft constitute leg space ventilation oral area point.
The present embodiment split shed is rectangular configuration, and the length direction of the rectangle is along hollow cylinder axial direction, several squares
Shape split ring is uniformly arranged around hollow cylinder periphery.
Smooth engagement between hollow cylinder and ventilation shaft.Guarantee is stuffy herein, and does not have excessive friction obstruction
Rotation.
When blowing, wind is acted on hemispherical Shell 1, and according to momentum theorem, hemispherical Shell 1 will drive cross-bar 2 and central shaft 3
Together around axis rotation, due to consolidating between central shaft 3 and hollow cylinder 4, hollow cylinder 4 is also by equidirectional, same to angular speed
Rotation.According to the relevant knowledge of rotation: the object rotated coaxially with same angular velocity, the off-axis heart is remoter, and linear velocity is bigger,
Therefore the outer wall speed of hollow cylinder 4 is greater than inner wall speed.Since air velocity is bigger, pressure is smaller, therefore outside air pressure is small
Pressure in hollow cylinder 4 forms draught head, and inner cavity air is caused to pass through 5 discharge of opening.Hollow cylinder 4 and ventilation shaft 6
Between smooth engagement, guarantee it is stuffy herein, and do not have excessive friction hinder rotation.Inside central shaft 3 and pipeline
Spring bearing is connected, and guarantees that equipment smooth rotation and can fall, or have the movement of horizontal direction.
Finally, it should be noted that being not intended to restrict the invention the foregoing is merely preferred embodiment of the invention, to the greatest extent
Invention is explained in detail referring to previous examples for pipe, for those skilled in the art, still can be right
Technical solution documented by foregoing embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
Within the scope of.
Undeclared part involved in the utility model is same as the prior art or is realized using the prior art.
