The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present embodiment provides a wind impeller device for a fan, the wind impeller device comprising a mounting seat assembly 1, an adjusting assembly and a control member 33, wherein a plurality of blades 2 are uniformly arranged on the mounting seat assembly 1 at intervals along the circumferential direction thereof; to achieve stable mounting of the blades 2, the mount assembly 1 includes a second cover plate 11 and a first cover plate 12, and the plurality of blades 2 are disposed between the second cover plate 11 and the first cover plate 12. Specifically, the first cover plate 12 is provided with a guide portion, and the second cover plate 11 is provided with a fixing portion. The adjusting assembly comprises a plurality of adjusting driving pieces 31 and at least one vibration sensing piece 32, wherein the adjusting driving pieces 31 are arranged corresponding to the blades 2 one by one and fixedly arranged on a fixing part of the second cover plate 11; the control member 33 is provided to the mount assembly 1. One end of the blade 2 is rotatably connected with the guide part of the first cover plate 12, and the other end of the blade 2 is fixedly connected with a driving shaft of the adjusting driving piece 31; the vibration induction piece 32 is arranged at a preset position of the mounting seat assembly 1; the control part 33 is respectively connected with the adjusting driving part 31 and the vibration sensing part 32, and the adjusting driving part 31 can adjust the windward angle of the blade 2; the vibration sensing member 32 can detect the vibration of the wind wheel device, and the control member 33 can receive the vibration signal of the vibration sensing member 32 and drive the adjusting driving member 31 to adjust the windward angle.

Wherein the predetermined range is a position where vibration of the wind impeller device can be detected. The installation seat assembly 1 is used for realizing the installation of a plurality of blades 2; meanwhile, the plurality of blades 2 are uniformly arranged in the circumferential direction of the mount base assembly 1 at intervals, so that the rotation of the mount base assembly 1 is more stable. Further, when the wind impeller device rotates, the vibration sensing member 32 can detect the vibration caused by the unbalance of the wind impeller device at the position where the vibration sensing member is located, convert the vibration into a vibration signal which can be recognized by the control member 33, and after the control member 33 receives the vibration signal, analyze the vibration signal and correspondingly control the adjusting driving member 31 to adjust the windward angle of the blade 2. It is worth explaining, the utility model discloses an adjust driving piece 31 and adjust the angle of attack of blade 2 for the resistance between blade 2 and the air can change, can realize carrying out automatic correction to the produced unbalance of wind impeller device under certain circumstances and resume balanced. Simultaneously, help reducing the process and the manpower and materials cost of artifical regulation blade 2, can help improving the interference killing feature of this wind impeller device when using to keep comparatively balanced state operation for a long time, thereby help prolonging its life.

It will be appreciated that the wind turbine arrangement when unbalanced causes local vibrations which propagate to the whole, causing the wind turbine arrangement to flutter. Therefore, when the wind impeller device is unbalanced, the vibration sensing member 32 sends a vibration signal detected on the wind impeller device to the control member 33, and the control member 33 determines that the wind impeller device is in an unbalanced state after receiving the vibration signal, so that the control member 33 controls the corresponding adjusting driving member 31 to adjust the windward angle of the blades 2, and the wind impeller device is helped to restore balance.

It is noted that the control member 33 is connected to the vibration sensing member 32 and the adjustment driving member 31, respectively. The vibration sensing part 32 is a vibration sensor, the control part 33 comprises a signal processor, the vibration sensing part 32 can convert vibration into vibration signals which can be received, processed and analyzed by the signal processor, unbalance is detected, and meanwhile, the signal processor can output corresponding commands according to the vibration signals sent by different vibration sensing parts 32, control corresponding adjusting driving parts 31 to make corresponding reactions so as to adjust the windward angle of the blade 2, further change the resistance between the blade 2 and the air and achieve the effect of correcting the balance.

Therefore, the vibration induction piece 32 is arranged close to the edge of the first cover plate 12 and/or the second cover plate 11, so that the vibration of the wind impeller device can be more accurately and timely induced, and the induction timeliness and reliability are improved.

For example, the vibration sensing member 32 may be set to be one, and when the control member 33 determines that the wind impeller device is in an unbalanced state after receiving the vibration signal, the adjustment driving member 31 may be sequentially adjusted to achieve the purpose of restoring the balance; or the vibration sensing member 32 may be provided in plurality, at this time, each vibration sensing member 32 corresponds to a plurality of adjusting driving members 31, and when the control member 33 determines that the wind turbine device is in an unbalanced state after receiving the vibration signal, the vibration sensing member 32 may be positioned, and the adjusting driving members 31 corresponding to the vibration sensing member 32 may be sequentially adjusted.

Specifically, the plurality of vibration sensing members 32 are numbered sequentially, and in the rotation process of the wind impeller device, the vibration sensing members 32 detect vibration signals in a predetermined range corresponding to the vibration sensing members in real time, and the control member 33 reads the vibration signals in real time; when the wind turbine blade wheel assembly is unbalanced, due to the centrifugal force generated by the uneven distribution of the radial mass relative to the wind turbine blade wheel assembly, this unbalanced centrifugal force may cause vibrations acting on the rotating wind turbine blade wheel assembly, since the blades 2 are more sensitive and accurate to the transmission of vibrations, and the vibration inducing means 32 are arranged at the edge of the first cover plate 12 and/or the second cover plate 11, which are more sensitive to vibrations. Therefore, the vibration sensing member 32 can detect the vibration amount of the wind impeller device more accurately and timely. The corresponding vibration induction part 32 can convert the vibration of the wind impeller device into an electric signal and transmit the electric signal to the control part 33, and the control part 33 is positioned to the blade 2 to be adjusted through the serial number, so that the corresponding adjusting driving part 31 can be controlled to act, the windward angle of the blade 2 can be adjusted, and the whole balance and stability of the wind impeller device can be further realized. It will be appreciated that the greater the opening angle of the blade 2, the greater the resistance between the blade 2 and the air.

It should be noted that the present invention provides a hardware architecture, which can utilize the conventional electrical signal transmission and control between the control member 33, the vibration sensing member 32 and the adjusting driving member 31 arranged thereon under the improvement of the structure of the wind impeller device for the fan, and adjust the windward angle of the blade 2 through the adjusting driving member 31 when the wind impeller device is in the vibration caused by imbalance, so as to change the resistance between the blade 2 and the air, thereby helping to achieve the balance effect.

In addition, still can reduce wind impeller device and because of the live time is long, and there is the balanced risk of destroying original wind impeller device such as dust or oil smoke, helps promoting production efficiency, promotes wind impeller device's life.
