In a specific embodiment, fig. 2 shows a structural schematic diagram of a wind concentrating device according to a specific embodiment of the present invention, and the wind concentrating device shown in fig. 2 includes an inner shaft 101, a rotating shaft 102, blades 103 and a spiral guide structure 104. The rotating shaft 102 is a hollow structure, and is sleeved on the inner shaft 101, and the inner shaft 101 and the rotating shaft 102 rotate together. The spiral guide structure 104 is in a space spiral shape, and the leading and trailing ends of the spiral guide structure 104 are fixedly connected to the rotating shaft 102 so as to be rotatable in synchronization with the rotating shaft 101. The plurality of blades 103 are spaced along the spatial helical trajectory of the helical guide structure 104, the helical guide structure 104 is a spatial helical structure comprising at least 2 effective helical turns, and within one effective helical turn, at least 3 blades 103 are arranged. Preferably, the blades 103 can be arranged along a spiral track at certain arc length intervals, and the number of the blades 103 in an effective number of turns is increased along with the increase of the number of turns of the spiral, so that the effective stress condition of the device is ensured, and the rotation efficiency is improved. In some other embodiments, such as the wind collecting device 100 shown in fig. 1, the inner shaft 101 may not be separately provided, and the rotation shaft 102 may be directly used as an output shaft to transmit the rotation motion. A flywheel may also be provided at the end of the rotating shaft 102 to improve the stability of the overall rotation and the rotational torque to better propel the transmission to rotate.

According to the definition of the generatrix in the science popularization china, the curved surface figure can be regarded as the track when the moving line moves, the moving line forming the curved surface is called as the generatrix, and in the application, the windward surface of the blade can also be regarded as the surface formed by the movement of the generatrix along the guide line. As can be seen from the structural schematic view of the blade in fig. 3, the blade 103 has a windward surface and a leeward surface, and the windward surface of the blade 103 is formed by controlling the movement of the bus bar 1032 by a guide line 1031, wherein the length direction away from the root of the blade 103 is taken as the guide line 1031, and the width direction perpendicular to the length direction is taken as the bus bar 1032. When the blade 103 is disposed on the wind collecting device, a thickness end surface of the blade 103 close to and facing the rotating shaft 102 is defined as a root 1036 of the blade, in fig. 3, the root 1036 of the blade is represented by a curve identical to a generatrix of the blade 103 at the thickness end surface, a center of the root 1036 of the blade on a windward surface is defined as a root center 1037, and a specific spatial angular relationship between the blade 103 and the rotating shaft 102 is specifically described below with reference to an embodiment of angular disposition of the blade 103:

as shown in the angle diagram of the blades in fig. 4a, each blade has a windward surface facing the rotation axis 102 and inclined toward the rotation axis 102, the spatial helical trajectory is a spatial logarithmic helical trajectory gradually expanding clockwise from top to bottom, and the windward surface of the blade faces counterclockwise, so that when driven by wind, the wind gathering device rotates clockwise. The blades 103 are arranged on the spatial spiral track in the above-mentioned manner, so that the blades and the spiral track have a spatial angular relationship (the direction of the blades towards the root points to the rotating direction of the spiral track), and the wind guided by the blades is guided to converge towards the inside of the spatial spiral track instead of being guided to spread to the outside of the device. An included angle β between an inner normal line of each blade at the root center on the windward surface thereof (i.e., a normal vector of the root center and a tangential plane of the windward surface at the root center in this embodiment) and an axis of the rotating shaft 102 in a rotating direction away from the spatial spiral track (i.e., the spatial spiral track rotates downward in this embodiment, and the direction away from the installation-required direction is upward) is an acute angle, so that the windward surface of each blade has a tendency of facing upward and toward the rotating shaft on the premise that the windward surface of each blade faces the rotating shaft 102 and inclines toward the rotating shaft 102, so as to guide the airflow toward the inside of the spatial spiral track, and finally converge to form a cyclone in the same rotating direction as the spatial spiral track (i.e., clockwise and downward in this embodiment) inside the spatial spiral track, and the cyclone can generate a certain negative pressure inside the spatial spiral track, so that the air above is sucked into the wind gathering device, meanwhile, the negative pressure generated by the cyclone can be converted into the airflow sucked into the spiral track from the upper part into the pushing force acting on the windward surface, the wind gathering device is further pushed to rotate, and the wind energy utilization rate is further improved.

In one preferred embodiment, as shown in the angle diagram of the blade in fig. 4b, at least part of the guide lines 1031 of the blade 103 may extend from the tangent of the blade root to the windward surface of the other blade in the rotation direction of the spatial spiral track of the blade and have a crossing point, the guide lines 1031 have a plurality of lines on the track of the generatrix 1032, but at least part of the guide lines 1031 may extend from the tangent of the blade root to the windward surface of the other blade, preferably, the larger the part is to guide the secondary impact effect of the airflow on the other blade, the embodiment is described by taking the guide lines 1031 passing through the midpoint of the generatrix 1032 as an example, assuming that the crossing point of the tangent to the windward surface of the other blade is a, the tangent of the blade root extends to the windward surface of the other blade in the rotation direction, and the direction of the guide lines extending from the tangent of the blade root to the crossing point a is the airflow direction when the airflow leaves the blade root, the wind acting on the blade can be guided to the other blade to form secondary impact on the other blade, the utilization rate of energy is improved, and the wind is prevented from directly discharging out of the device and being dissipated into the air after acting on the blade.

With continued reference to the blade angle diagram of figure 4c, which is a horizontal projection of the blade leading line within an effective number of turns, the angle a between the projection of the tangent 1034 and the tangent 1034 'on the horizontal plane towards the axis of rotation 102, taken through the tangent 1034' of the blade at the point of intersection a towards the blade root, on the windward surface of the blade at which the point of intersection a is located, is an obtuse angle, it being recognized that in figure 4a the obtuse angle is a spatial angle, and for the sake of a more visual presentation, the projection angle of figure 4b is taken as an explanation, both of which have the technical effect that it is actually possible to avoid the spreading of the air flow towards the outside of the device, while continuing to direct the air flow of the secondary impacts inwards, it being noted that the obtuse angle may not be too close to 90 deg., the closer to 90 deg., the more detrimental to the inward direction of the air flow by the blade, in a further preferred embodiment, the obtuse angle is set to be greater than 135 °. Through the angle setting, the airflow acting on the blade 103 can continuously impact other blades, the airflow is guided from outside to inside and is converged inside the spiral guide structure 104 along the rotation direction of the spiral track, a plurality of airflows finally form a cyclone inside the spiral guide structure 104, and negative pressure formed by the cyclone inside the spiral guide structure 104 can attract external airflow to enter the device, so that the wind energy utilization rate is further improved.

In a particular embodiment, the blade root is provided with a mounting portion 1033, and the mounting portion 1033 may be a threaded post for mounting and securing to the helical guide structure. The guide lines 1031 and the generatrices 1032 can be straight lines, curved lines or a combination thereof, and the windward surfaces of the formed blades are correspondingly flat surfaces, curved surfaces or a combination thereof, preferably, the guide lines 1031 and the generatrices 1032 are taken from logarithmic spirals, and the windward surfaces of the blades formed by the guide lines and the generatrices of the logarithmic spirals can better guide the airflow to the inner parts of the logarithmic spiral tracks of the spaces to form cyclones by matching with the logarithmic spiral tracks of the spaces.

With continued reference to fig. 4d, the blade angle is represented by a schematic projection of the horizontal plane at the center of the blade root, and the tangent direction of the guide line 1031 at the blade root mounting point is disposed to be deviated to the inner side of the helix of the helical trajectory, i.e. the guide line 1031 has an intersection point B (assumed to be the blade root center) at the helical trajectory 1042, where an angle γ exists between the tangent 1034 of the guide line 1031 and the tangent 1043 of the helical trajectory at the intersection point B, preferably, the angle γ is an acute angle. The angle is set, so that the blades can be conveniently arranged on the spiral track, the blades can be guided to flow to the tangential direction close to the spiral track to be converged, the swept area of the blades can be increased to a certain extent, and the rotation efficiency of the device is improved. In other embodiments, the crossing point B is taken as a normal line 1035 pointing to the axis of the rotating shaft, the first tangent line 1034 is located in a region of an included angle θ formed by the second tangent line 1043 and the normal line 1035, when the first tangent line 1034 is close to the normal line 1035, the included angle γ may also be an obtuse angle, the effect of guiding the air flow toward the inside of the spiral track under the angle is general, part of the air flow is guided to the outer edge of the blade and then diffused to the outside of the wind gathering device, if the angle γ is greater than the included angle θ, the windward surface of the blade will be away from the rotating shaft, and at this time, most of the wind acting on the windward surface of the blade will be guided to the outside of the wind gathering device, and the air flow cannot be guided to the inside of the spiral track.

Continuing to refer to the blade angle schematic diagram in fig. 4e, which shows a blade schematic diagram in a top view direction, the spatial spiral track 1042 rotates clockwise, the plurality of blades 103 are arranged at intervals on the spatial spiral track 1042, windward surfaces of the blades 103 are all inclined towards the rotation axis, a cyclone in the same direction as the rotation of the spatial spiral track 1042 is formed in the spatial spiral track under the action of wind, the cyclone forms an air pressure difference in the spatial spiral track, and attracts air above the spatial spiral track to enter the device, at this time, the airflow entering the device can also act on the windward surfaces of the blades from a vertical direction, the blades are pushed to rotate again, and by virtue of the arrangement among the blades, each blade is partially exposed on the windward surface in the top view direction, so that each blade of the device can obtain an acting force of the airflow attracted inwards due to the air pressure difference, and the rotation efficiency of the wind gathering device is improved.

In summary, the blades 103 are arranged along the spatial spiral track around the rotating shaft 102, and in combination with each blade having a windward surface facing the rotating shaft 102 and inclined towards the rotating shaft 102, the direction of the guide line of the blade towards the root is biased towards the rotating direction of the spatial spiral track, and this arrangement can guide the airflow to the inside of the spatial spiral track and finally converge to form a cyclone, if the direction of the guide line of the blade towards the root is opposite to the rotating direction of the spatial spiral track, the windward surface of the blade will be in the direction away from the rotating shaft, and the blade in this state cannot guide the airflow to the inside of the spatial spiral track but guide the airflow to the outside of the wind collecting device. In the above embodiment, the windward surface of the blade is concave, i.e. the concavity of the windward surface faces the rotation axis 102, and is inclined at an angle such that the blade 103 has a direction facing the axis of the rotation axis 102, which can be defined according to the rotation direction of the spatial spiral trajectory. The inclined angle can be defined as an included angle formed by an inner normal line of the windward surface of each blade at the center of the root and an axis far away from the rotating direction of the spatial spiral track, the included angle is an acute angle, and by means of the combined action of the spatial spiral track arrangement, the inclination of the windward surface of the blade towards the rotating shaft and the acute angle formed by the inner normal line of the windward surface of the blade at the center of the root and the axis far away from the rotating direction of the spatial spiral track, a cyclone is formed inside the spatial spiral track, external airflow is guided to the inside of the device by the pressure difference between the inside and the outside of the device, and the orientation and the angle of the blade 103 enable the windward surface of the blade to face the airflow guided to the inside of the device, so that the wind gathering device is driven to rotate more efficiently.
