[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 7 , one embodiment of the present invention is: a device for monitoring blade deformation of a wind power generation device, comprising a support column 1, the back side of the support column 1 is provided with bolt holes on all four sides, the support column 1 is fixedly mounted on the outer wall of the cabin of the wind power generation device by bolts, the front side of the support column 1 is fixed with a square plate 2, and the front side of the square plate 2 is fixed with a cylinder 3 on all four sides; A laser detection assembly 31 is arranged on the front of the four cylinders 3. The laser detection assembly 31 includes a U-shaped frame 311. The U-shaped frame 311 is fixed on the front of the four cylinders 3. A casing 312 is fixed on the top surface of the U-shaped frame 311. A servo motor 313 is fixedly installed on the top of the casing 312. A plurality of heat dissipation ports are provided on the outer wall of the casing 312. A shaft control module is arranged inside the servo motor 313. The control module of the servo motor 313 controls the rotation direction of the shaft of the servo motor 313. A laser instrument 314 is rotatably installed on the inner wall of the U-shaped frame 311. Two shafts of the laser instrument 314 are respectively penetrated and rotatably installed above and below the inner wall of the U-shaped frame 311. The top surface of the shaft of the laser instrument 314 is fixedly connected to the bottom surface of the shaft of the servo motor 313. A Laser transmitter head, an L-shaped frame 315 is fixedly installed on the left side of the top surface of the laser instrument 314, and a photosensitive instrument 316 is penetrated and fixedly installed on the right side of the L-shaped frame 315. A photosensitive plate is arranged on the left side of the photosensitive instrument 316, and the photosensitive plate of the photosensitive instrument 316 is located above the laser transmitter head of the laser instrument 314. During the reciprocating half-circle rotation of the laser instrument 314 to the left and right, the laser instrument 314 irradiates the entire blade, and the photosensitive instrument 316 will receive the laser reflected by the blade. When the laser received by the photosensitive instrument 316 is offset, the photosensitive instrument 316 sends data to the staff's mobile phone through the wireless network, so that the staff can timely discover and locate the position of the blade deformation, so as to avoid the device for monitoring the blade deformation of the wind power generation equipment being difficult to monitor and locate the blade deformation position when the equipment is in use, resulting in poor equipment monitoring effect.

[0022] The U-shaped frame 311 has an anti-shake component 32 on the left side of the inner wall. The anti-shake component 32 includes a vertical pad 321. An arc-shaped spring piece 322 is fixed on the left side of the vertical pad 321. The arc-shaped spring piece 322 is located in the middle of the U-shaped frame 311. A convex plate 323 is fixed on the side of the arc-shaped spring piece 322 away from the vertical pad 321. The left side of the convex plate 323 is fixedly connected to the right side of the laser instrument 314. The arc-shaped spring piece 322 is in a straight state when not rotating. The convex plate 323 drives the arc-shaped spring piece 322 to rotate back and forth half a circle. The arc-shaped spring piece 322 is deformed on the vertical pad 321. Under the elastic force of the arc-shaped spring piece 322, the arc-shaped spring piece 322 slows down the shaking of the laser instrument 314 during the rotation process, so that the laser instrument 314 will not shake violently when rotating, so as to avoid the laser instrument 314 from shaking violently when rotating when the device for monitoring the deformation of the blades of the wind power generation equipment is in use, resulting in inaccurate monitoring.

[0023] When in use, the staff installs the equipment on the cabin of the wind power generation equipment through the bolt holes on the support column 1. The support column 1 supports the square plate 2, and the square plate 2 supports the cylinder 3. Since the blades of the wind power generation equipment are large blades, during the deformation monitoring process of the blades, the blade length is long and it is difficult to determine the position of the deformation. At this time, the cylinder 3 supports the U-shaped frame 311, and the U-shaped frame 311 supports the casing 312. The servo motor 313 in the casing 312 is started, and the control module in the servo motor 313 controls the shaft of the servo motor 313 to rotate back and forth half a circle. The shaft of the servo motor 313 drives the laser instrument 314 to rotate back and forth half a circle. The laser instrument 314 rotates back and forth half a circle in the U-shaped frame 311. The laser instrument 314 drives the L-shaped frame 315 to rotate back and forth half a circle. The L-shaped frame 315 drives The photosensitive instrument 316 rotates back and forth half a circle to start the laser instrument 314. The laser emission head of the laser instrument 314 emits a laser. When the laser emitted by the laser instrument 314 irradiates the blade, the blade reflects the laser emitted by the laser instrument 314. During the half-circle rotation of the laser instrument 314, the laser instrument 314 irradiates the entire blade. The photosensitive instrument 316 receives the laser reflected by the blade. When the laser received by the photosensitive instrument 316 is offset, the photosensitive instrument 316 sends data to the staff's mobile phone through the wireless network, so that the staff can find and locate the position of the blade deformation in time, so as to prevent the equipment from being unable to monitor and locate the position of the blade deformation when in use, thereby avoiding the problem that the device for monitoring the blade deformation of the wind power generation equipment is difficult to monitor and locate the blade deformation position when in use, resulting in poor equipment monitoring effect.

[0024] While the shaft of the servo motor 313 drives the laser instrument 314 to rotate back and forth half a circle, the laser instrument 314 drives the convex plate 323 to rotate back and forth half a circle, and the convex plate 323 drives the arc-shaped spring piece 322 to rotate back and forth half a circle. The arc-shaped spring piece 322 is deformed on the vertical pad 321. Under the elastic force of the arc-shaped spring piece 322, the arc-shaped spring piece 322 slows down the vibration of the laser instrument 314 during the rotation process, so that the laser instrument 314 does not vibrate violently when rotating, thereby preventing the laser instrument 314 from vibrating violently when the equipment is in use, thereby avoiding the problem of inaccurate monitoring caused by the laser instrument 314 vibrating violently when the device for monitoring the deformation of the blades of the wind power generation equipment is in use.

During the reciprocating half circle rotation of the concave round shell 54, the concave round shell 54 shields the laser instrument 314, so that the concave round shell 54 protects the laser emission head of the laser instrument 314 in strong wind weather, so as to avoid the laser emission head of the laser instrument 314 being damaged by strong wind when the device for monitoring the blade deformation of the wind power generation equipment is in use, resulting in poor equipment monitoring effect.

The top surface of the circular frame 57 is fixedly connected to the bottom surface of the laser instrument 314. The circular frame 57 is located on the left side of the bottom surface of the laser instrument 314. The strip plate 55 is against the bottom of the concave round shell 54 to make the concave round shell 54 more capable of facing the wind, so as to avoid the poor windproof effect of the equipment caused by the weak windproof ability of the concave round shell 54 when the device for monitoring the deformation of the blades of the wind power generation equipment is in use.

[0029] A method for using a device for monitoring blade deformation of a wind power generation device comprises the following steps: S1. The staff installs the equipment on the nacelle of the wind power generation equipment through the bolt holes on the support column 1; S2, the laser instrument 314 irradiates the entire blade. When the laser received by the photosensitive instrument 316 is offset, the photosensitive instrument 316 sends the data to the staff's mobile phone through the wireless network, so that the staff can find and locate the position of the blade deformation in time; S3, the arc-shaped spring piece 322 reduces the shaking of the laser instrument 314 during the rotation process, so that the laser instrument 314 does not vibrate violently during the rotation; S4, short column 44 supports L-shaped frame 315, so that photosensitive instrument 316 on L-shaped frame 315 will not shake in strong wind weather; S5, the shield 47 will shield the photosensitive instrument 316 to reduce the damage of the photosensitive instrument 316 due to rain; S6. The concave shell 54 shields the laser instrument 314, so that the concave shell 54 protects the laser transmitting head of the laser instrument 314 in strong wind weather; S7. The strip plate 55 is against the bottom of the concave round shell 54, so that the concave round shell 54 has a stronger ability to face the wind.

At the same time, the L-shaped strip plate 41 drives the vertical plate 43 to rotate back and forth half a circle, and the vertical plate 43 drives the short column 44 to rotate back and forth half a circle. The short column 44 supports the L-shaped frame 315. When the weather is in a strong wind state, the short column 44 supports the L-shaped frame 315. The L-shaped frame 315 is supported in a row so that in strong wind weather, the L-shaped frame 315 will not shake when it rotates back and forth half a circle left and right, and the photosensitive instrument 316 on the L-shaped frame 315 will not shake in strong wind weather, thereby preventing the photosensitive instrument 316 from shaking in strong wind weather when the equipment is in use, thereby avoiding the problem of poor monitoring effect of the equipment in strong wind weather due to the photosensitive instrument 316 shaking in strong wind weather when the device for monitoring blade deformation of wind power generation equipment is in use.

[0031] While the vertical plate 43 drives the short column 44 to rotate back and forth half a circle, the short column 44 drives the inclined bar ring 45 to rotate back and forth half a circle, the inclined bar ring 45 drives the inclined plate 46 to rotate back and forth half a circle, and the inclined plate 46 drives the shielding plate 47 to rotate back and forth. On rainy days, the shielding plate 47 blocks the photosensitive instrument 316, so that when the equipment is monitored on rainy days, the shielding plate 47 will block the photosensitive instrument 316, reducing the damage of the photosensitive instrument 316 caused by rain, thereby avoiding the problem of the photosensitive instrument 316 being damaged by rain on rainy days when the device for monitoring the blade deformation of the wind power generation equipment is in use.

[0032] While the vertical plate 43 drives the short column 44 to rotate back and forth half a circle, the short column 44 drives the annular plate 51 to rotate back and forth half a circle, the annular plate 51 drives the L-shaped rod 52 to rotate back and forth half a circle, the L-shaped rod 52 drives the circular plate 53 to rotate back and forth half a circle, and the circular plate 53 drives the concave shell 54 to rotate back and forth half a circle, so that during the process of the concave shell 54 rotating back and forth half a circle, the concave shell 54 blocks the laser instrument 314, so that in strong wind weather, the concave shell 54 protects the laser emitting head of the laser instrument 314 to prevent the laser emitting head of the laser instrument 314 from being damaged by strong wind when the equipment is used in strong wind weather, thereby avoiding the problem of poor equipment monitoring effect caused by the laser emitting head of the laser instrument 314 being damaged by strong wind when the device for monitoring blade deformation of wind power generation equipment is in use.

[0033] While the circular plate 53 drives the concave circular shell 54 to rotate back and forth half a circle, the concave circular shell 54 drives the strip plate 55 to rotate back and forth half a circle, the strip plate 55 drives the transverse plate 56 to rotate back and forth half a circle, the transverse plate 56 drives the circular frame 57 to rotate back and forth half a circle, and the circular frame 57 rotates along with the laser 314, so that the strip plate 55 is against the bottom of the concave circular shell 54, making the concave circular shell 54 more capable of facing the wind, thereby preventing the concave circular shell 54 from having a weak wind-facing ability when the equipment is used in strong wind weather, thereby avoiding the problem of poor wind-proof effect of the equipment caused by the weak wind-facing ability of the concave circular shell 54 when the device for monitoring blade deformation of wind power generation equipment is in use.
