Detailed ways

The present invention is described in more detail below in conjunction with accompanying drawing example:

1-7, the present invention mainly consists of a base 1, a housing conical blade 2, a support rod 3, a spring 4, an upper turntable 5, a switch paddle 6, an upper turntable slideway 7, a switch seat 8, and a switch paddle Sliding plate 9, multistage switch interface 10, lower turntable 11, slide block 12, fork 13 several parts constitute.

As shown in Figure 1: the four shell conical blades 2 are fixedly connected with the bottom ends of the four swing rods 13 respectively, and the two adjacent swing rods 13 are assembled at an angle of 90 degrees; the spring 4 is assembled on the upper turntable 5 and the lower Between the turntables 11, and the centerline is the central axis of the base 1, both ends are fixedly connected to the upper turntable 5 and the lower turntable 11 respectively; the switch base 8 is fixedly connected to the base 1. As shown in Figure 3: the top of the swing rod 13 is connected to the upper turntable 5 through a pin shaft 15, and the swing rod 3 and the upper turntable 5 constitute a revolving pair; the inner ring of the upper turntable 5 is in contact with the outer ring of the upper turntable slideway 7, 5 can rotate around the central axis of the upper turntable slideway 7, and can also slide along the axial direction of the upper turntable slideway 7. The upper turntable 5 and the upper turntable slideway 7 form a line contact high pair; the upper turntable slideway 7 is fixed Connected to the base 1 and installed coaxially with the base 1; the lower surface of the switch paddle 6 is fixedly connected with the upper surface of the thrust bearing 14, the lower surface of the thrust bearing 14 is fixedly connected with the upper turntable 5, and the upper turntable 5 slides along the upper turntable When the track 7 rotates and slides, it drives the switch paddle conductor 18 on the switch paddle 6 to slide along the switch paddle slide plate 9, and the switch paddle conductor 18 is connected to the multi-stage switch interface 10, and the switch is connected. As shown in Figure 4: one end of the support rod 3 is connected to the lower turntable 11 through a pin shaft 16, and the support rod 3 and the lower turntable 11 form a revolving pair; the tapered roller bearing 17 and the inner ring of the lower turntable 11 are interference fitted, and the inner ring Interference fit with the base 1, then the lower turntable 11 and the base 1 form a rotational fit relationship. As shown in Figure 6: the multi-level switch interface 10 is fixedly connected with the switch base 8 with a columnar insulator 19, which can make each level of switch interface in a disconnected state; the switch paddle conductor 18 is fixedly connected on the switch paddle 6, and its function It is the interface for turning on the switch. As shown in Figure 7: the other end of the support rod 3 is connected to the slider 12 through a pin shaft 21, the support rod 3 and the slider 12 form a rotating pair, and the slider 12 and the swing bar 13 form a moving pair.

From the above assembly relationship, it can be seen that when the housing conical blade 2 rotates around the central axis of the base 1 , a centrifugal force will be generated in a direction away from the central axis of the base 1 . The centrifugal force acts on the bottom end of the swing rod 13, which can be decomposed into the force along the direction of the swing rod 13 and the force perpendicular to the swing rod 13. The force along the direction of the swing rod 13 acts on the upper turntable 5, so that the upper turntable 5 is subjected to a downward force. . According to the principle of leverage, the force perpendicular to the fork 13 takes the slide block 12 as a fulcrum to generate a reverse balance force on the top of the fork 13, and this balance force acts on the upper turntable 5. Two downward forces act on the top of the spring 4, the spring 4 is compressed, and the upper turntable 5 descends. Similarly, when the rotating speed of the conical blade 2 of the housing decreases, the centrifugal force decreases, and the elastic force generated after the spring 4 is compressed forces the upper turntable 5 to rise. FIG. 1 is a state view of the switch in a windless environment. At this time, the switch paddle conductor 18 is located above the multi-level switch interface 10, and the switch is in an off state. Fig. 2 is a view of a working state, in which the switch plectrum 6 descends with the upper turntable 5, and the switch is turned on.

In a windless environment, the switching system is in equilibrium. At this time, the switch paddle conductor 18 fixedly connected to the switch paddle 6 is located above the multi-stage switch interface 10, and the switch is in an off state.

In a windy environment, the force on the outer shell of the conical blade 2 of the shell is weakened by its own conical structure, and the resistance to the wind is small; the resistance to the wind on the inner shell of the conical blade 2 of the shell is proportional to the area of the bottom of the cone Proportionally, the suffered wind resistance is larger, and the resultant force that the four casing cone blades 2 inner casings are subjected to is larger than the casing. And because the orientations of the four housing conical blades 2 around the central axis of the base 1 are consistent, so in a windy environment, the four housing conical blades 2 will generate a rotational moment consistent with the orientation of their tops, and the four housings The conical blade 2 can realize the action of rotating around the central axis of the base 1 , and at the same time, the upper turntable 5 and the lower turntable 11 can be driven to rotate around the base 1 through the swing rod 13 and the support rod 3 .

When the shell conical blade 2 rotates, a centrifugal force is generated, and the centrifugal force acts on the bottom end of the swing rod 13. This force can be decomposed into a downward component force along the swing rod 13 direction and an obliquely upward component force perpendicular to the swing rod 13. The component force acts on the upper turntable 5, so that the upper turntable 5 produces a downward component force. According to the principle of leverage, the force perpendicular to the swing rod 13 takes the slider 12 as the fulcrum to generate a reverse balance force on the top of the swing rod 13, and the balance force acts on the upper turntable 5, so that the upper turntable 5 generates a downward force Participate. Under the action of two downward component forces, the upper turntable 5 descends, the spring 4 is compressed, and simultaneously drives the paddle switch 6 to descend, the switch paddle conductor 18 descends, and the switch is connected.

As the wind speed increases, the rotation speed of the conical blades 2 around the base 1 increases, the centrifugal force increases, the downward force on the upper turntable 5 increases, and the descending distance of the upper turntable 5 increases, and the force of the spring 4 increases. As the deformation under pressure increases, the descending distance of the paddle switch 6 increases, the descending distance of the switch paddle conductor 18 increases, and the level of the multi-level switch interface 10 connected by the switch paddle conductor 18 increases. The switch can realize the function of controlling multi-stage output with the increase of wind force.

Similarly, when the wind speed decreases, the rotating speed of the conical blade 2 of the casing decreases, and the centrifugal force decreases. Under the force of the elastic force of the spring 4, the switch paddle conductor 18 gradually rises, and the connected multi-stage switch interface 10 level gradually decreases. The switching system gradually returns to the initial equilibrium state, and the switch is disconnected. The switch can realize the function of controlling multi-level output as the wind force decreases.
