Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0038] Please see Figures 1 to 7 This invention proposes a measuring device for the dimensions of wind turbine hybrid tower segments, applicable to fields including but not limited to wind power generation and construction, for measuring annular cylindrical segments. This invention can comprehensively and accurately measure various parameters of the annular cylindrical segments, effectively reducing measurement errors and meeting the high-precision installation requirements of wind turbine hybrid towers. A single operator can complete the segment measurement work, improving measurement efficiency and reducing labor costs. Detailed descriptions are provided below using specific embodiments.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The measuring device for the wind turbine hybrid tower segment 100 provided by this utility model can measure the height, diameter, and thickness of the wind turbine hybrid tower segment 100. Specifically, the height is the height along the central axis of the wind turbine hybrid tower segment 100, the diameter is the radial diameter of the wind turbine hybrid tower segment 100, and the thickness is the thickness of the outer wall of the wind turbine hybrid tower segment 100.

[0040] like Figure 1 , Figure 2 As shown, in practical scenarios, the wind turbine hybrid tower segment 100 may be placed in different orientations, such as on a horizontal surface or on a slope. Measuring the height and thickness of the wind turbine hybrid tower segment 100 is relatively easy and accurate. However, when measuring the diameter of the wind turbine hybrid tower segment 100, it is necessary to determine its center point. When the wind turbine hybrid tower segment 100 is placed on a slope, determining the center point is difficult. The measuring device for the wind turbine hybrid tower segment 100 provided by this invention can accurately measure the diameter of the wind turbine hybrid tower segment 100.

[0041] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment of this utility model, the measuring device for the wind power hybrid tower segment 100 may include a pole 10, a support assembly 20, a connecting plate 30, a laser emitter 40, and a laser rangefinder 50.

[0042] Specifically, the pole 10 serves as the main installation body, and the support assembly 20, connecting plate 30, laser emitter 40, and laser rangefinder 50 are installed on the pole 10.

[0043] Specifically, such as Figure 4 , Figure 5 As shown, the top of the support assembly 20 is connected to the upright 10, and the bottom of the support assembly 20 extends towards the bottom of the upright 10. The support assembly 20 includes at least two support portions 210, which are symmetrical about the upright 10 and are used to contact the ground. The upright 10 rests against the inner wall of the wind turbine hybrid tower segment 100, and the two support portions 210 are used to contact the ground. Under the action of the support portions 210 of the support assembly 20 and the upright 10, the upright 10 can be stably placed on the inner wall of the wind turbine hybrid tower segment 100.

[0044] Specifically, such as Figure 4 , Figure 5 As shown, there are two connecting plates 30, which are rotatably connected to the upright 10. For example, the connecting plates 30 rotate along the central axis of the upright 10. There are two connecting plates 30 on both sides of the upright 10, and the two connecting plates 30 are the same size.

[0045] Specifically, such as Figure 3 , Figure 4 As shown, there are at least two laser emitters 40, with one laser emitter 40 located at the center of each connecting plate 30.

[0046] Specifically, such as Figure 3 , Figure 4 As shown, the laser rangefinder 50 is connected to the pole 10 and is located between the two connecting plates 30. For example, the laser rangefinder 50 and the laser emitter 40 are located on the same horizontal plane. The irradiation end of the laser rangefinder 50 and the irradiation end of the laser emitter 40 face the support 210. It should be understood that "facing the support 210" does not mean the direction facing the support 210, but rather that the irradiation end of the laser rangefinder 50 and the irradiation end of the laser emitter 40 need to extend beyond the support 210 and irradiate the inner wall of the wind turbine hybrid tower segment 100.

[0047] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment of the present invention, the measuring device proposed in this embodiment is described in detail for measuring different wind power hybrid tower segments 100. First, the upright 10 is placed against the inner wall of the wind power hybrid tower segment 100, and the two support parts of the support assembly 20 are set on the ground, so that the upright 10 is stable inside the wind power hybrid tower segment 100.

[0048] Furthermore, the two support portions of the support assembly 20 can be located on the inner wall of the bottom end of the wind turbine hybrid tower segment 100, that is, the two support portions of the support assembly 20 are located on the bottom circle of the wind turbine hybrid tower segment 100. As for how to adjust the support assembly 20 so that the two support portions of the support assembly 20 can be located on the bottom circle of wind turbine hybrid tower segments 100 of different sizes, it can be described through specific embodiments below. For now, we will only consider the measurement of one specification of wind turbine hybrid tower segment 100 for explanation.

[0049] like Figure 3 , Figure 4 As shown, since the two support components 20 are arranged symmetrically (axially symmetrically) along the central axis of the upright 10, and the two support parts of the support components 20 are located on the bottom circle of the wind power hybrid tower segment 100, it indicates that the central axis of the upright 10 is parallel to the axis of the wind power hybrid tower segment 100.

[0050] Secondly, the connecting plate 30 can be rotated along the central axis of the upright 10 so that both sides of the connecting plate 30 contact the inner wall of the wind power hybrid tower segment 100. At this time, the two connecting plates 30 are symmetrically (axially symmetrically) arranged along the central axis of the upright 10, that is, the two connecting plates 30 are symmetrically (axially symmetrically) arranged along the center line of the wind power hybrid tower segment 100.

[0051] like Figure 3 As shown, the laser emitter 40, located at the center of the connecting plate 30, is situated on the vertical bisector of the connecting plate 30. When the laser emitter 40 operates, it illuminates the center of the wind turbine hybrid tower segment 100 and ultimately the inner wall of the wind turbine hybrid tower segment 100. The point where the lasers intersect, illuminated by the two laser emitters 40 on the two connecting plates 30, can be identified as the center of the wind turbine hybrid tower segment 100.

[0052] Then, the laser rangefinder 50 can be used to illuminate the confirmed center point to measure the diameter of the wind power hybrid tower segment 100.

[0053] For example, since the pole 10 is supported against the inner wall of the wind turbine hybrid tower segment 100, and the laser rangefinder 50 is connected to the pole 10, the laser rangefinder 50 measures the distance between the pole 10 and the inner wall of the wind turbine hybrid tower segment 100. Since the pole 10 and the laser rangefinder 50 are located on the diameter of the wind turbine hybrid tower segment 100, the diameter of the wind turbine hybrid tower segment 100 can be obtained by directly adding the distance measured by the laser rangefinder 50 to the dimensions of the pole 10 and the laser rangefinder 50.

[0054] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6In one embodiment of the present invention, the support component 20 may include a support portion 210 and a connecting component.

[0055] Specifically, the top of the support 210 is rotatably connected to the upright 10, and its bottom extends towards the bottom of the upright 10. There are two support 210s, which are symmetrically arranged along the central axis of the upright 10. The plane containing the two support 210s intersects the straight line containing the upright 10. Intersection means that the plane containing the two support 210s and the straight line containing the upright 10 form an acute angle, and there is no situation where the straight line containing the upright 10 lies within the plane containing the two support 210s.

[0056] like Figure 4 , Figure 6 As shown, the connecting component is connected between the two support portions 210 to adjust the distance between the bottoms of the two support portions 210.

[0057] Specifically, the connecting assembly includes at least two connecting rods 220, with adjacent connecting rods 220 rotatably connected. The two outermost connecting rods 220 are rotatably connected at both ends to the support portion 210. The rotation axis of the connecting rod 220 is parallel to the rotation axis of the support portion 210. Figure 4 , Figure 6 As shown, when adjusting the connecting rod 220, the distance between the bottoms of the two support parts 210 can be adjusted so that the bottom of the support part 210 is located on the bottom circle of the wind power hybrid tower segment 100 of different sizes.

[0058] For example, when the connecting assembly includes only two connecting rods 220, one end of the first connecting rod 220 is rotatably connected to a support 210. One end of the second connecting rod 220 is rotatably connected to another support 210. The other end of the first connecting rod 220 is rotatably connected to the other end of the second connecting rod 220.

[0059] Please see Figure 4 , Figure 6 , Figure 7 As shown, in one embodiment of this utility model, the measuring device further includes a connecting block 60 and a rotating plate 70. The connecting block 60 is connected to the outer wall of the upright 10, the support part 210 is rotatably connected to the rotating plate 70, and the rotating plate 70 is rotatably connected to the connecting block 60. The connecting block 60 can rotate along the central axis of the upright 10.

[0060] The rotation axis of the rotating plate 70 is perpendicular to the straight line of the upright 10. When the upright 10 is in the vertical direction, the rotating plate 70 is in the horizontal direction.

[0061] By setting a rotating plate 70, the support assembly 20 can be rotated along the rotating plate 70, thereby changing the angle between the plane containing the support assembly 20 and the straight line containing the upright 10. For example... Figure 7 As shown, if in the initial state, the upright 10 is placed against the inner wall of the wind turbine hybrid tower segment 100, and the bottom end of the support part 210 does not contact the inner wall of the wind turbine hybrid tower segment 100, the support assembly 20 can be rotated along the rotating plate 70 so that the bottom end of the support part 210 contacts the inner wall of the wind turbine hybrid tower segment 100. When the bottom end of the support part 210 contacts the inner wall of the wind turbine hybrid tower segment 100, it indicates that the central axis of the upright 10 is parallel to the axis of the wind turbine hybrid tower segment 100.

[0062] Specifically, the included angle between the straight lines where the two support parts 210 are located is 0° to 120°; the included angle between the plane where the two support parts 210 are located and the straight line where the upright 10 is located is 0° to 60°.

[0063] Please see Figure 4 , Figure 5 In one embodiment of this utility model, the bottom height of the upright 10 is higher than the bottom height of the support 210.

[0064] Specifically, the measuring device also includes a foot support 80, which is rotatably connected to the bottom of the upright 10, and the rotation axis of the foot support 80 is perpendicular to the straight line of the upright 10.

[0065] Specifically, the foot support 80 is connected to the bottom of the upright 10 and extends in a direction away from the upright 10. The foot support 80 is a telescopic pole.

[0066] Please see Figure 3 , Figure 4 , Figure 5 In one embodiment of this utility model, a scale line is provided on the side wall of the pole 10 to measure the height of the wind power hybrid tower segment 100.

[0067] Specifically, the measuring device also includes a mounting block 110 and a measuring ruler 120. The mounting block 110 is slidably connected to the top side wall of the pole 10, and the measuring ruler 120 is connected to the mounting block 110. The measuring ruler 120 extends toward the side away from the support 210 to measure the side wall thickness of the wind power hybrid tower segment 100.

[0068] In summary, the wind turbine hybrid tower segment measurement device disclosed in this utility model can comprehensively and accurately measure the parameters of the annular cylindrical segments, effectively reducing measurement errors and meeting the high-precision installation requirements of wind turbine hybrid towers. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0069] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
