[0020] The utility model will be further explained in combination with the drawings and specific embodiments.
[0021] Reference Figure 1 , Figure 2 and Figure 3 , the embodiment provides a kind of wind turbine tower fixing monitoring device, including light beam emitting element 1 and light beam receiving element 2, specifically:
[0022] First fixed mounting bracket 200 is arranged in wind turbine tower 100, and the first fixed mounting bracket 200 is provided with a flexible connecting line 300, and the free end of the flexible connecting line 300 is connected with plumb 400 for keeping the vertical state of flexible connecting line 300.
[0023] The light beam emitting element 1 adopts laser emitter or infrared emitter.
[0024] The light beam emitting element 1 is arranged on the plumb 400 and the light beam emitted thereby is coaxial with the flexible connecting line 300, or in other words, the plumb 400 and the light beam emitted thereby are located on the same straight line. When the wind power tower 100 is tilted, the light beam emitted by the light beam emitting element 1 always remains vertical.
[0025] The light beam receiving element 2 is arranged at the bottom inside the wind power tower 100, and the light beam emitting element 1 is located above the light beam receiving element 2.
[0026] The light beam receiving element 2 comprises a second fixed mounting bracket 20 arranged inside the wind power tower 100, a circular light beam receiving plate 21 arranged on the second fixed mounting bracket 20, a controller 22, a display 23, an alarm module 24 and a wireless communication module 25. Figure 2 The installation of the controller 22, the display 23, the alarm module 24 and the wireless communication module 25 is not shown in the figure, but the installation positions of the controller 22, the display 23, the alarm module 24 and the wireless communication module 25 do not affect their use, and thus will not be described in detail here.
[0027] When the wind power tower 100 is tilted, the light beam receiving element 2 tilts with the wind power tower 100, and the tilt of the wind power tower 100 can be reflected according to the tilt of the light beam receiving element 2.
[0028] The light beam emitting element 1 is located above the light beam receiving element 2, and the circular light beam receiving plate 21 is uniformly and spacedly provided with a plurality of photosensitive element groups to form a photosensitive element array; the photosensitive element adopts a photosensitive resistor. It should be noted that in general, the brightness inside the wind power tower 100 is low, and will not cause the photosensitive element on the circular light beam receiving plate 21 to generate an electric signal, but when the photosensitive element on the circular light beam receiving plate 21 receives the light beam emitted by the light beam emitting element 1, the photosensitive element will generate an electric signal change. Each photosensitive element can be numbered in advance, and each photosensitive element generates an electric signal corresponding to an inclination angle output value, which can reflect the tilt of the wind power tower.
[0029] In the specific embodiment, preferably, the controller adopts an MT8321 module.
[0030] The wireless communication module 25 adopts a 3G communication module.
[0031] The photosensitive element array 21, the display 23, the alarm module 24 and the wireless communication module 25 are respectively electrically connected with the controller 22.
[0032] When the wind turbine tower 100 is tilted, the light beam emitting element 1 emits a light beam on the light beam receiving element 2, and the light beam receiving element 2 receives the light beam, so that the tilt of the wind turbine tower 100 is monitored efficiently and accurately, and timely feedback is given to the workers, so as to ensure the safe and stable operation of the wind turbine tower 100.
[0033] Further, the circular light beam receiving plate 21 is provided with a transparent cover plate (not shown in the figure), which does not affect the light transmission of the light beam and protects the circular light beam receiving plate 21 through the transparent cover plate.
[0034] The wireless communication module 25 can also be one of a 4G communication module, a 5G communication module, an NB-IoT communication module, and a LoRa communication module, or any combination of the three.
[0035] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and detail without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
