Dry and transmission；Inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..The operation principle of wind turbine and turbocompressor are essentially identical, only
It is since gas flow rate is relatively low, pressure change is little, generally without the concern for the variation of gas specific volume, i.e., using gas as can not
The fluid of compression is handled.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides the double end that a kind of air quantity is big, air quantity is stablized
Wind turbine.
The purpose of this utility model is achieved through the following technical solutions：A kind of double-head fan, including casing, casing are in column
The endface position of shape, casing is provided with air inlet, and the cylinder location of casing is provided with air outlet, rotating mechanism, institute are provided in casing
The rotating mechanism stated includes rotation axis, fan blade A and fan blade B, and rotation axis is arranged along chassis axial, and one end of rotation axis is circumferentially installed
There are multiple fan blade A, the other end of rotation axis that multiple fan blade B are circumferentially installed, fan blade A is close to air inlet and fan blade B is located at outlet air
At mouthful；
The blade face of the fan blade A and the axis direction of rotation axis have α angles, and the size of α angles is 45o ~ 90o, wind
For leaf A close to one end of rotation axis one end separate for root and end, the right side in the root of fan blade A is solid by fritter protrusion
Determine on the rotating shaft, to form equidistant gap, the entirety formed between the ends fan blade A between the left side and rotation axis of the roots fan blade A
Same equidistant spacing and the equidistant air stream for forming high pressure between outer diameter and casing；
Straight line where the root of the fan blade B is parallel with the axis of rotation axis, and fan blade B is C-shaped, and along rotation axis radial direction
The center of rotation axis, the root of fan blade B and end three are point-blank.
The width of the ends fan blade A is more than the width of its root.
The casing includes left cabinet and right cabinet, and multiple latch posts, right machine are arranged in parallel on the cylinder of left cabinet
Multiple bolt ears are provided on the cylinder of shell, the end of latch post is provided with screw thread, and latch post is inserted into bolt ear and passes through nut
Locking.
The left cabinet and right cabinet is less than right cabinet in junction, the diameter of left cabinet, and left cabinet is inserted into right cabinet
In and locked by clamping screw.
The utility model has the following advantages：It is drawn an airflow by the way that fan blade A is arranged, by the way that fan blade B is arranged by sucking
Air-flow extrudes, and two processes are realized by two fan blades respectively, and the air quantity generated is bigger than the air quantity that single fan blade generates；
Gap between the root and shaft of fan blade A so that when the air-flow of sucking is excessive, escaped automatically by the gap so that wind
The air quantity that leaf A is generated is stablized.
Description of the drawings
Fig. 1 is the schematic diagram that fan blade A is connected with casing；
Fig. 2 is the schematic diagram that fan blade B is connected with casing；
In figure：1- rotation axis, 2- fan blades A, 3- fan blade B, 4- fritter protrusion, 5- bolt ears, 6- clamping screws.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited to
It is as described below.
As depicted in figs. 1 and 2, a kind of double-head fan, including casing, casing are in the form of a column, the endface position of casing be provided with into
The cylinder location in air port, casing is provided with air outlet, is provided with rotating mechanism in casing, the rotating mechanism include rotation axis 1,
Fan blade A2 and fan blade B3, rotation axis 1 are arranged along chassis axial, and one end of rotation axis 1 is circumferentially equipped with multiple fan blade A2, rotation axis
1 other end is circumferentially equipped with multiple fan blade B3, and fan blade A2 is close to air inlet and fan blade B is located at air outlet.
Further, the axis direction of the blade face of the fan blade A2 and rotation axis 1 is with α angles, the size of α angles
45o ~ 90o, fan blade A2 are close to one end of rotation axis 1 one end separate for root and end, the right side in the root of fan blade A2
