[0001] This application relates to the field of wind power generation technology, specifically to a wind-collecting device and a wind turbine generator set. Background Technology

[0002] The angle between the wind turbine rotor and the wind direction has a significant impact on the power generation efficiency of the wind turbine. Generally, the power generation efficiency of a wind turbine is highest when the rotor is directly facing the wind. In related technologies, a wind vane is installed on the nacelle to determine the current wind direction, and then the orientation of the wind turbine rotor is adjusted to face the wind. However, because the nacelle deforms over long-term use, the installation angle of the wind vane may deviate after the pre-installed position on the nacelle. This leads to a significant error in the wind direction angle subsequently determined by the wind vane, affecting the power generation efficiency of the wind turbine. Utility Model Content

Detailed Implementation

[0020] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0021] The wind turbine generator set provided in this application embodiment may include a body and a wind-aligning device. The wind-aligning device is installed on the body. After the installation position of the wind-aligning device is calibrated, the orientation of the impeller on the body can be adjusted according to the wind direction angle determination result of the wind-aligning device, so that the impeller can be aligned with the wind direction, thereby improving the power generation efficiency of the wind turbine generator set.

[0022] Figure 1 This is a schematic diagram of the structure of a wind-conducting device provided for an exemplary embodiment of this application. Figure 2 for Figure 1 Enlarged diagram of point A in the diagram. Figure 3 This is a schematic diagram of the structure of a wind vane provided for an exemplary embodiment of this application. Figures 1 to 3As shown, the wind-guiding device 100 provided in this application embodiment may include a reference object 110 and a wind vane 120. Both the reference object 110 and the wind vane 120 are mounted on the aforementioned body. When installing the wind vane 120, the reference object 110 can be used as a reference to calibrate the initial installation position of the wind vane 120, so that the wind vane 120 can more accurately determine the wind direction angle, which is beneficial to improving the subsequent accurate adjustment of the impeller orientation.

[0023] It should be noted that in a wind turbine generator set, the reference object 110 can be the main shaft, transmission chain, etc. of the wind turbine generator set, and the orientation of the reference object 110 is the same as the orientation of the impeller of the wind turbine generator set.

[0024] like Figure 1 and Figure 2 As shown, the airflow device 100 may further include a first angle detection element 130, which is disposed on the reference object 110. The first angle detection element 130 can be used to detect a preset axis (reference) of the reference object 110. Figure 1 The angle between the axis indicated by the middle arrow B and the reference direction.

[0025] In one embodiment, the reference direction may include due south, due north, etc.

[0026] like Figures 1 to 3 As shown, the wind vane 120 may include a base 121 and a body 122. The body 122 is rotatably engaged with the base 121. Under the action of wind, the body 122 can rotate relative to the base 121, and the direction in which the body 122 faces is the direction of the wind.

[0027] It should be noted that the base 121 is provided with an marking part 123. Correspondingly, the wind-conducting device 100 may include a second angle detection element 140, which is disposed on the marking part 123. The second angle detection element 140 can be used to detect the central axis of the marking part 123 (see reference). Figure 1 The angle between the axis indicated by the middle arrow C and the aforementioned reference direction.

[0028] It should be understood that the angle values ​​detected by the first angle detection element 130 and the second angle detection element 140 can respectively represent the angle between the preset axis and the reference direction, and the angle between the central axis of the marking part 123 and the reference direction. When the angle values ​​detected by both are equal, it can be considered that the preset axis and the central axis of the marking part 123 are parallel to each other. At this time, the position of the base 121 can be considered as the initial installation position of the wind vane 120, and the orientation of the reference object 110 (the impeller of the wind turbine generator) is parallel to the central axis of the marking part 123. In this way, under the action of wind, the body 122 rotates relative to the base 121. Based on the rotation angle between the body 122 and the base 121, the current wind direction angle can be determined, and then the impeller is rotated (the reference object 110 and the wind vane 120 will rotate with the impeller) so that the impeller faces the wind direction, thereby improving the power generation efficiency of the wind turbine generator.

[0029] In other words, in practical applications, after the weather vane 120 is installed on the fuselage, the angle between the preset axis and the reference direction is first confirmed by observing the angle value of the first angle detection element 130; then, the current angle value of the second angle detection element 140 is observed to confirm the angle between the central axis of the marking part 123 and the reference direction; if the angle value detected by the first angle detection element 130 and the angle value detected by the second angle detection element 140 are not equal (due to the deformation of the fuselage, the installation position of the base 121 in the fuselage is inaccurate), then the position of the base 121 can be adjusted until the angle value detected by the first angle detection element 130 and the angle value detected by the second angle detection element 140 are equal, thus completing the calibration of the installation angle of the weather vane 120.

[0030] In one embodiment, the identification part 123 may include color identification, number identification, letter identification, etc.

[0031] In one embodiment, the marking portion 123 may include a first marking and a second marking, which are respectively disposed on opposite sides of the base 121. The center line connecting the first marking and the second marking constitutes the central axis of the marking portion 123. A second angle detection element 140 is disposed on the first marking or the second marking. Thus, the measuring reference plane of the second angle detection element 140 is equivalent to the radial reference plane of the central axis of the marking portion 123, and can directly correspond to the tilt direction of the central axis of the marking portion 123, thereby more accurately measuring the angle between the central axis of the marking portion 123 and the reference direction.

[0032] In one embodiment, the first identifier can be represented by the letter "S" and the second identifier can be represented by the letter "N".

[0033] The wind-following device 100 and wind turbine generator provided in this application embodiment detect the angle between the preset axis of the reference object 110 and the reference direction by setting a first angle detection element 130 on the reference object 110; and detect the angle between the central axis of the marking part 123 and the reference direction by setting a second angle detection element 140 on the marking part 123 of the base 121. Then, the installation position of the base 121 of the wind vane 120 is adjusted according to the angle values ​​detected by the first angle detection element 130 and the second angle detection element 140. In this way, the influence of nacelle deformation on the installation accuracy of the wind vane 120 can be eliminated, the installation angle of the wind vane 120 can be calibrated more accurately, the installation accuracy of the wind vane 120 can be improved, thereby reducing the error in the determination of the wind direction angle and improving the power generation efficiency of the wind turbine generator.

[0034] like Figure 1 and Figure 2 As shown, the reference object 110 may include a shaft 111 and an end plate 112. The axis of the shaft 111 is collinear with or parallel to a preset axis. The end plate 112 is connected to the shaft 111 and is perpendicular to the preset axis. The first angle detection element 130 is disposed on the end plate 112. In this way, on the one hand, the end plate 112 can provide a larger assembly position for the first angle detection element 130, making it easier to install. On the other hand, since the end plate 112 is perpendicular to the preset axis and the first angle detection element 130 is disposed on the end plate 112, its measurement reference surface is equivalent to the radial reference surface of the preset axis, which can directly correspond to the tilt direction of the preset axis, thereby more accurately measuring the angle between the preset axis and the reference direction.

[0035] In one embodiment, the shaft 111 may be the main shaft of a wind turbine generator set; or, the shaft 111 may be other shaft-like structures distributed parallel to the main shaft of the wind turbine generator set.

[0036] In one embodiment, the end plate 112 may be a brake disc, bearing end cover, impeller locking disc, etc. in a wind turbine generator set.

[0037] like Figure 2 As shown, the first angle detection component 130 may include a first mounting base 131 and a first angle sensor 133. The first mounting base 131 is disposed on the reference object 110 and has a first mounting groove 132. The first angle sensor 133 is disposed in the first mounting groove 132.

[0038] It should be understood that the first mounting slot 132 can effectively limit the first angle sensor 133, prevent the first angle sensor 133 from shaking, and improve the installation stability of the first angle sensor 133.

[0039] In one embodiment, the first mounting groove 132 and the first angle sensor 133 can be relatively fixed by means of snap-fitting, bonding or other methods.

[0040] In one embodiment, the first angle sensor 133 may include an inclinometer, a digital compass, etc.

[0041] It should be noted that, considering that the reference object 110 in a wind turbine generator set is usually made of metal, the first mounting base 131 can be a magnetic mounting base. This not only makes it easy to quickly assemble the first mounting base 131 onto the reference object 110, but also makes it easy to quickly adjust the installation position of the first mounting base 131, thus improving its applicability.

[0042] In one embodiment, the first mounting base 131 and the reference object 110 can also be relatively fixed by means of snap-fit, welding, bonding, threaded engagement, etc.

[0043] like Figure 2 As shown, the first angle sensor 133 is provided with a first display unit 134, which can be used to display the angle value currently detected by the first angle sensor 133.

[0044] It should be noted that the first display section 134 protrudes outside the first mounting groove 132. This avoids the inner wall of the first mounting groove 132 from obstructing the first display section 134, making it convenient for staff to quickly view the angle value displayed on the first display section 134.

[0045] In one embodiment, the first display unit 134 may include a display screen, a pointer clock, etc.

[0046] like Figure 3 As shown, the second angle detection component 140 may include a second mounting base 141 and a second angle sensor 143. The second mounting base 141 is disposed on the marking part 123 and has a second mounting groove 142. The second angle sensor 143 is disposed in the second mounting groove 142.

[0047] It should be understood that the second mounting slot 142 can effectively limit the second angle sensor 143, prevent the second angle sensor 143 from shaking, and improve the installation stability of the second angle sensor 143.

[0048] In one embodiment, the second mounting slot 142 and the second angle sensor 143 can be relatively fixed by means of snap-fitting, bonding or other methods.

[0049] In one embodiment, the second angle sensor 143 may include an inclinometer, a digital compass, etc.

[0050] It should be noted that, considering that the base 121 of the wind vane 120 in a wind turbine generator set is usually made of metal, a magnetic mounting base can be used for the second mounting base 141. This not only makes it easy to quickly assemble the second mounting base 141 onto the base 121 of the wind vane 120, but also makes it easy to quickly adjust the installation position of the second mounting base 141, thus improving its applicability.

[0051] In one embodiment, the second mounting base 141 and the base 121 of the weather vane 120 can also be fixed to each other by means of snap-fit, welding, bonding, threaded connection, etc.

[0052] like Figure 3 As shown, the second angle sensor 143 is provided with a second display unit 144, which can be used to display the angle value currently detected by the second angle sensor 143.

[0053] It should be noted that the second display section 144 protrudes from the second mounting groove 142. This avoids the inner wall of the second mounting groove 142 from obstructing the second display section 144, making it convenient for staff to quickly view the angle value displayed on the second display section 144.

[0054] In one embodiment, the second display unit 144 may include a display screen, a pointer, etc.
