Working principle: when the invention is used, the wind speed sensor 4 and the servo motor 521 are controlled by programming through the external controller and the control system, the external wind speed is detected through the wind speed sensor 4, when the external wind speed detected through the wind speed sensor 4 is larger than the set value range of the wind speed, the information is transmitted to the external control system through an electric signal, so that the external control system drives the first bevel gear 522 to rotate forward through automatically opening the servo motor 521, the first bevel gear 522 drives the second bevel gear 525 and the screw rod 524 in the inner cavity thereof to rotate, the thread bush 526 on the outer side of the screw rod 524 drives the supporting disc 527 to move downwards, the supporting disc 527 drives the fixed rod 53 to move downwards, the upper end of the fixed rod 53 drives the supporting shaft 513 to move downwards, the other end of the supporting shaft 513 drives the side plates 512 and the U-shaped plate 510 to tilt towards the direction of the swinging rod 75 by taking the connecting shaft 59 as a pivot, and simultaneously, the side plate 512 drives one end of the torsion spring 511 to twist, and one end of the connecting rod 55 drives the buffer component 54 to move towards the swing rod 75 after penetrating through the through groove 58 on the shell cover 57, when the wind force is overlarge, the swing amplitude of the swing rod 75 is overlarge, when the swing rod 75 contacts the foam pad 545, the effect of buffering and preventing gravity impact is effectively achieved on the swing rod 75, and meanwhile, the second arc-shaped rubber plate 544 is used for further buffering and protecting, the hollow rubber plate 542 and the honeycomb plate 543 in the inner cavity thereof are used for effectively buffering and protecting, so that the swing rod 75 is convenient for limiting the swing amplitude of the swing rod 75 through the buffer component 54 during frequent swing, reducing the swing amplitude of the swing rod and simultaneously performing buffering and damping and protecting effects on parts of the bladeless wind power generation equipment, the service life of the device is prolonged, the use effect is improved, when the wind speed is reduced to a set range value, the servo motor 521 is automatically opened again through an external control system, so that the output end of the servo motor 521 reversely rotates, and finally, all parts of the buffer mechanism 5 are reset as in the principle, so that the buffer assembly 54 is far away from the swing rod 75, the device can conveniently recover to normal vibration amplitude, and the influence on the swing amplitude of the device when the wind speed is small is avoided, so that the power generation efficiency is reduced.

For the arrangement of the wind speed sensor 4, it should be noted that, when the external wind speed is low or no wind, the above scheme of mounting the wind speed sensor 4 at the upper end of the top cover 32 may be adopted to detect the wind speed at a lower level for the sake of integration; in order to prevent the device itself from moving to affect the wind speed detection when the external wind speed is high, the wind speed sensor 4 may be separately provided at a stationary position near the device to detect, that is, separately provided from the device.

Example 2:

On the basis of the buffering protection device for bladeless wind power generation provided in embodiment 1, embodiment 2 provides a buffering protection method for bladeless wind power generation, which includes: acquiring a current wind speed, and adjusting the position of the buffer assembly 54 according to the current wind speed; in one possible embodiment, the current wind speed may be obtained by the wind speed sensor 4 in example 1, and after the current wind speed is obtained, the position of the buffer assembly 54 is adjusted according to whether the current wind speed exceeds the wind speed preset value; if the current wind speed exceeds the wind speed preset value, the servo motor 521 drives the whole buffer mechanism 5 to move, so that the buffer assembly 54 moves towards the direction of the swing rod 75, thereby forming a buffer shock absorption protection effect on the swing of the swing rod 75, reducing the swing amplitude and frequency, improving the use safety and prolonging the service life; if the current wind speed is lower than the wind speed preset value, the servo motor 521 drives the whole buffer mechanism 5 to move, so that the buffer assembly 54 moves towards the direction away from the swing rod 75, thereby releasing the swing limit on the swing rod 75, enabling the swing rod 75 to operate normally and improving the power generation efficiency. The specific implementation structure of each component is described in detail in embodiment 1, and will not be described herein.

In this embodiment, the preset wind speed value may be a high wind speed threshold value, for example, as long as the wind speed is greater than v1, the specific v1 value is set in advance by a worker, and the standard of setting is that after the wind speed is considered to be exceeded, a large amplitude and frequency oscillation is easily caused to the swing rod 75, which may cause damage to parts. The design standard of the buffer assembly 54 is designed by taking the normal swing amplitude of the swing rod 75 as a standard, and when the buffer assembly 54 is close to the swing rod 75 and is successfully encircled, the size of the space left for the swing rod 75 to swing is the normal swing amplitude of the swing rod 75.

Based on this, two cases occur at the time of actual use.

First case: when the current wind speed is greater than the wind speed preset value, the buffer assembly 54 is moved towards the direction of the swing rod 75 through the servo motor 521, and the swing rod 75 is limited and buffered. For example, when the current wind speed is above v1, the buffer mechanism 5 is driven to move by the servo motor 521, so that the buffer assembly 54 moves towards the direction of the swing rod 75, the amplitude and the frequency of the swing rod 75 are limited while buffering is formed, the vibration effect can be reduced, and the damage to parts is avoided.

Second case: when the current wind speed is smaller than the wind speed preset value, the buffer assembly 54 is moved towards the direction away from the swing rod 75 through the servo motor 521, and limiting buffer on the swing rod 75 is canceled. For example, when the current wind speed is below v1, the buffer mechanism 5 is reversely driven to move by the servo motor 521, so that the buffer assembly 54 moves towards a direction away from the swing rod 75, and the restriction on the swing rod 75 is removed, so that the power generation efficiency is improved.

In an alternative to this embodiment, a precondition for adjusting the position of the damper assembly 54 in response to wind speed may also be set: setting a preset time length, and adjusting the position of the buffer assembly 54 when the wind speed duration time of the same gear exceeds the preset time length; the gear in this embodiment is one gear greater than the preset wind speed value and one gear less than the preset wind speed value. The predetermined length of time is at least greater than the length of time required for the cushioning assembly 54 to adjust the position for one round. The reason for this is to reduce the situation that the wind speed is shifted again when the wind speed gear change is detected to carry out position adjustment, so that the adjustment fails and the adjustment needs to be repeated again; after the preset time length is set, when the wind speed is maintained in the same gear for more than the preset time length, the position adjustment can be performed only if the gear change can not occur in a short time, so that the condition that the wind speed gear change is too fast, the adjustment fails and the adjustment needs to be repeated again is reduced.

The entire structure of the energy capturing device refers to the buffering protection device for bladeless wind power generation in embodiment 1, and will not be described herein.

In a specific embodiment, the control module and the wind speed acquisition module are both one, and the control module is respectively connected with the servo motor 521 of each energy capturing device so as to perform uniform position adjustment control on the buffer assemblies 54 of all the energy capturing devices; the wind speed acquisition module is arranged on one energy capturing device or is independently arranged near all the energy capturing devices, and all the energy capturing devices are arranged according to a preset distance array. In a specific embodiment, the wind speed acquisition module includes a wind speed sensor 4, and the control module acquires the current wind speed through the wind speed sensor 4, and after acquiring the current wind speed, the control module controls the servo motor 521 to adjust the position of the buffer assembly 54 according to whether the current wind speed exceeds a wind speed preset value. The wind speed preset value divides the wind speed into two gears, the wind speed is higher than the wind speed preset value and is higher than the wind speed preset value, the buffer assembly 54 needs to be adjusted in the direction close to the swing rod 75, the wind speed is lower than the wind speed preset value and is lower than the wind speed preset value, and the buffer assembly 54 needs to be adjusted in the direction far away from the swing rod 75.

In a specific embodiment, a timer module may be further provided, where a preset time length is built in the timer module, the timer module is connected to the control module or directly provided in the control module, and when the control module detects that the wind speed is shifted to a certain gear through the wind speed acquisition module, the timer module starts to count, and after the preset time length is reached, the timer is ended, and the control module starts to perform position adjustment. The predetermined length of time is at least greater than the length of time required for the cushioning assembly 54 to adjust the position for one round. The reason for this is to reduce the situation that the wind speed is shifted again when the wind speed gear change is detected to carry out position adjustment, so that the adjustment fails and the adjustment needs to be repeated again; after the preset time length is set, when the wind speed is maintained in the same gear for more than the preset time length, the position adjustment can be performed only if the gear change can not occur in a short time, so that the condition that the wind speed gear change is too fast, the adjustment fails and the adjustment needs to be repeated again is reduced.
