A wind turbine tower is made up of multiple towers connected end to end, and there are multiple ladders connected end to end inside the tower. A guide rail will be installed on the surface of the ladder, and the anti-climbing device will slide along the guide rail. If the guide rail is longer than the length of the wind turbine tower, the guide rails will be against each other end to end during the installation of the tower, and the guide rails will be unable to connect; if the guide rail is shorter than the length of the wind turbine tower, it is easy to cause the gap between the guide rails to be too large after the tower is connected, and the anti-climbing device will have certain risks when used.

The following is an explanation of the terms involved in the embodiments of this application.

[0047] Wind power tower: also known as wind turbine tower, is an energy device that converts wind energy into electrical energy. The wind drives the wind wheel on the top of the tower to rotate, and the mechanical energy of the wind wheel is transmitted to the wind turbine, which then converts this mechanical energy into electrical energy for the power grid or users.

[0048] A wind turbine tower is made up of multiple towers connected end to end, and there are multiple ladders connected end to end inside the tower. A guide rail is installed on the surface of the ladder, and the anti-climbing device slides along the guide rail. If the guide rail is longer than the length of the wind turbine tower, the guide rails will be against each other when the tower is installed, and the guide rails will be unable to connect; if the guide rail is shorter than the length of the wind turbine tower, it is easy to cause the gap between the guide rails to be too large after the tower is connected, and there is a certain risk when using the anti-climbing device. Therefore, when installing a wind turbine tower, the distance between the end face of the wind turbine tower flange and the end face of the guide rail inside the tower is a key measurement point.

[0049] In the prior art, during the day when the wind speed is low, a worker uses a fishing line to pull the two ends of the flange surface tightly so that the fishing line and the flange are in close contact. The fishing line can be fixed to the outer surface of the flange with a magnet, and then another worker uses a ruler to measure the distance between the fishing line and the guide rail, thereby obtaining the required distance between the end face of the flange and the end face of the guide rail. On the one hand, when the wind blows, the fishing line will swing with the wind, resulting in measurement deviation and being easily affected by environmental interference; on the other hand, the above operation is relatively complicated and inconvenient.

[0050] In view of this, an embodiment of the present application provides an end face measurement tool for a wind turbine tower, wherein a flange is provided on the wind turbine tower, and a guide rail is provided inside the wind turbine tower, and the tool is used to measure the distance between the end face of the flange and the end face of the guide rail. The tool comprises: a mounting assembly, a scale assembly and a measuring assembly, wherein the scale assembly is used to be arranged inside the wind turbine tower, and the scale assembly has a first position, and the first position is flush with the end face of the flange, the mounting assembly is used to be arranged on the guide rail, and the measuring assembly is connected to the mounting assembly, and the measuring assembly is used to emit a light beam along a first direction, and the light beam is flush with the end face of the guide rail. The measuring assembly is fixed on the guide rail by the mounting assembly, so that the measuring assembly can move with the movement of the guide rail, so that the light beam emitted by the measuring assembly along the first direction is always flush with the end face of the guide rail. The scale assembly is arranged inside the wind turbine tower, and has a first position, and the first position is flush with the end face of the flange, which serves as a reference for measurement. During measurement, the light beam falls on the scale assembly, and the distance between the position of the light beam on the scale assembly and the first position is obtained, so as to facilitate obtaining the distance between the end face of the flange and the end face of the guide rail. The guide rail moves according to the distance until the light beam coincides with the first position, at which time the end face of the guide rail is flush with the end face of the flange, thereby achieving the accuracy of guide rail installation. Therefore, the end face measurement tool in the embodiment of the present application is relatively simple to operate and relatively convenient to use.

[0051] Combine the following Figures 1 to 5 The present application is described in detail with reference to the accompanying drawings and specific embodiments. Figure 1 A schematic diagram of the structure of an end face measurement tool provided in an embodiment of the present application; Figure 2 for Figure 1 A magnified view of the structure of part A; Figure 3 for Figure 1 Structural diagram of the installation components and measurement components; Figure 4 for Figure 1 Schematic diagram of the structure of the middle scale assembly; Figure 5 A schematic structural diagram of the first scale member of the end surface measurement tool provided in an embodiment of the present application.

[0052] An embodiment of the present application provides an end face measuring tool for a wind turbine tower. A flange is provided on the wind turbine tower. A guide rail 20 is provided inside the wind turbine tower 10. The end face measuring tool is used to measure the distance between the end face 11 of the flange and the end face 21 of the guide rail. The end face measuring tool includes: an installation component 100, a ruler component 200 and a measuring component 300; the ruler component 200 is used to be set on the inner side of the wind turbine tower 10, and the ruler component 200 has a first position, and the first position is flush with the end face 11 of the flange; the installation component 100 is used to be set on the guide rail 20, and the measuring component 300 is connected to the installation component 100, and the measuring component 300 is used to emit a light beam along a first direction, and the light beam is flush with the end face 21 of the guide rail; the movement of the guide rail 20 is determined according to the distance between the position of the light beam at the ruler component 200 and the first position.

[0053] A flange is provided on the wind turbine tower 10, and a guide rail 20 is provided inside the wind turbine tower 10. Figure 1 As shown, the flange includes a front end face and a rear end face, the front end face is located above the rear end face, and the distance between the front end face and the rear end face along the second direction represents the thickness of the flange. It can be understood that the front end face is the flange end face 11.

[0054] It should be noted that the second direction is perpendicular to the first direction and parallel to the extension direction of the wind turbine tower 10. The distance between the flange end face 11 and the guide rail end face 21 needs to be measured, so as to adjust the position of the guide rail 20 according to the distance so that the guide rail end face 21 is flush with the flange end face 11.

[0055] The mounting assembly 100 is used to fix the measuring assembly 300 on the guide rail 20. The mounting assembly 100 is detachably connected to the guide rail 20, so as to facilitate the adjustment of the position of the measuring assembly 300 to adapt to guide rails 20 of different sizes and measurement requirements.

[0056] The scale assembly 200 is used to be arranged inside the wind turbine tower 10, and the scale assembly 200 has a first position, which is flush with the flange end surface 11. Exemplarily, the scale assembly 200 is a scale with scale lines, and the first position on the scale assembly 200 is flush with the flange end surface 11, and the first position can be the 0 scale line.

[0057] The measuring assembly 300 is disposed on the mounting assembly 100, and is used to emit a light beam along a first direction, and the light beam is flush with the guide rail end surface 21. It can be understood that the distance between the position of the light beam at the scale assembly 200 and the first position represents the distance between the flange end surface 11 and the guide rail end surface 21. The guide rail 20 moves according to the distance until the light beam coincides with the first position, at which time the guide rail end surface 21 is flush with the flange end surface 11.

[0058] The end face measuring tool in the embodiment of the present application fixes the measuring component 300 on the guide rail 20 by means of the mounting component 100, so that the measuring component 300 can move with the movement of the guide rail 20, so that the light beam emitted by the measuring component 300 along the first direction is always flush with the end face 21 of the guide rail. The scale component 200 is arranged inside the wind power tower 10 and has a first position, which is flush with the flange end face 11 and serves as a reference for measurement. During measurement, the light beam falls on the scale component 200, and the distance between the flange end face 11 and the guide rail end face 21 is obtained according to the distance between the position of the light beam on the scale component 200 and the first position. The guide rail 20 moves according to the distance until the light beam coincides with the first position, at which time the guide rail end face 21 is flush with the flange end face 11, so as to achieve the accuracy of the installation of the guide rail 20. Therefore, the end face measuring tool in the embodiment of the present application is relatively simple to operate and relatively convenient to use.

[0059] In some embodiments, the end face measurement tool provided in the embodiments of the present application further includes a trigger assembly 400, which is disposed on the scale assembly 200. The trigger assembly 400 is used to detect the position of the light beam on the scale assembly 200. The difference between the position and the first position is the distance between the guide rail end face 21 and the flange end face 11.

[0060] The trigger assembly 400 is arranged on the scale assembly 200, and the trigger assembly 400 corresponds to the scale line on the scale assembly 200. When the light beam is emitted on the scale assembly 200, the trigger assembly 400 can detect the position of the light beam on the scale assembly 200. The difference between the position and the first position is the distance between the guide rail end face 21 and the flange end face 11. When the first position is the 0 scale line, the position of the light beam on the scale assembly 200 is the distance between the guide rail end face 21 and the flange end face 11.

[0061] In some embodiments, the measuring component 300 includes a control component 310 and a measuring component 320, wherein the control component 310 is electrically connected to the measuring component 320, and the measuring component 320 is used to send a light beam. The control component 310 controls the on or off of the light beam emitted by the measuring component 320. A display screen is also provided on the control component 310, and the control component 310 is electrically connected to the measuring component 300, and is used to display the position of the light beam on the ruler component 200 or the difference between the position and the first position, so as to facilitate observation by the operator.

[0062] In some embodiments, a broadcaster may be further provided on the control member 310, and the broadcaster is electrically connected to the trigger assembly 400 and the control member 310 respectively to broadcast the position of the light beam in the scale assembly 200 or the difference between the position and the first position.

[0063] In some other embodiments, the end face measurement tool provided by the embodiments of the present application, the measuring component 300 includes a control component 310 and a measuring component 320, the control component 310 is electrically connected to the measuring component 320, the measuring component 320 is set on the installation component 100, the measuring component 320 is used to be set toward the wind turbine tower 10, the measuring component 320 is used to emit a light beam, and the control component 310 controls the opening or closing of the light beam emitted by the measuring component 320.

[0064] In specific implementation, the control element 310 is electrically connected to the measuring element 320, and a control switch is provided on the control element 310 to control the measurement element 320 to emit a light beam along the first direction. The control switch can be a physical button, a touch screen or a knob, so that the operator can control the emission of the light beam as needed.

[0065] For example, when the control switch is a knob switch, the intensity of the light beam can be adjusted by turning the knob at different angles to adapt to different environments inside the wind turbine tower.

[0066] In some embodiments, the control element 310 may also be equipped with an indicator light to provide intuitive visual feedback to determine whether the indicator light beam is being emitted, and also to provide a certain degree of visibility in a relatively dim environment. For example, the indicator light may have different colors, such as green for normal emission of the light beam, black for the light beam off state, and red for a warning or error state.

[0067] The embodiment of the present application does not limit the specific structure of the measuring element 320. For example, the measuring element 320 may be a laser emitter or an infrared emitter.

[0068] In some embodiments, there are multiple measuring members 320, each of which emits a light beam along the first direction, and each of which is spaced apart along the extension direction of the guide rail end surface 21 of the guide rail 20. The light beam of each measuring member 320 along the first direction is flush with the guide rail end surface 21 of the guide rail 20, so as to compare and calibrate the position of each light beam in the scale assembly 200. By comparing and calibrating the position of each light beam in the scale assembly 200, the error caused by the deviation of the light beam path or the unevenness of the scale assembly 200 can be reduced, thereby improving the measurement accuracy.

[0069] In some embodiments, a player is also disposed on the control member 310 , and when it is detected that the light beam in the first direction is flush with the guide rail end surface 21 of the guide rail 20 , the player emits a prompt sound.

[0070] In some possible implementations, in the end face measurement tool provided in the embodiment of the present application, the measurement component 300 further includes a fixing member 330 , the fixing member 330 is disposed on the mounting component 100 , and the fixing member 330 is connected to the measuring member 320 .

[0071] When implementing it specifically, Figure 1 and Figure 3 The fixing member 330 includes a first fixing plate and a second fixing plate, one end of the first fixing plate is connected to the measuring member 320, and the other end is connected to the second fixing plate, one end of the second fixing plate is connected to the first fixing plate, and the other end is connected to the mounting assembly 100. In particular, when the guide rail 20 moves, the fixing member 330 enhances the stability of the measuring member 320, thereby preventing the displacement of the measuring member 320, thereby affecting the accuracy of the measurement.

[0072] It should be noted that the connection between the measuring piece 320 and the first fixing plate can be a snap connection or a screw connection to ensure the stability of the measuring piece 320 on the fixing plate, and this application does not limit this.

[0073] In addition, a self-locking nut or an anti-loosening gasket may be placed between the fixing member 330 and the measuring member 320 to prevent the measuring member 320 from loosening or displacement deviation due to accidental vibration.

[0074] In some embodiments, the end face measurement tool provided in the embodiments of the present application, the scale assembly 200 includes a scale member 210 and an abutment member 220, the abutment member 220 is arranged on the scale member 210, the lower end surface of the abutment member 220 is flush with the first position of the scale member 210, and the scale member 210 is used for detachable connection with the wind turbine tower 10.

[0075] Specifically, the abutting member 220 is disposed on the scale member 210 , the scale member 210 and the abutting member 220 are L-shaped, and the extending direction of the abutting member 220 is parallel to the first direction.

[0076] The scale element 210 has a first position, which can be set according to actual conditions. For example, the first position can be at the 0-mm scale line or the 5-mm scale line, and the present application does not impose any limitation on this.

[0077] The detachable connection between the scale member 210 and the wind turbine tower 10 can flexibly adjust the position of the scale member 210 according to the position adjustment of the measuring component 300 so that the light beam emitted by the measuring component 300 can fall on the scale member 210 .

[0078] The lower end surface of the abutment member 220 is flush with the first position of the scale member 210 , so that the first position of the scale member 210 is flush with the flange end surface 11 .

[0079] The embodiment of the present application does not limit the specific structure of the ruler member 210. For example, the ruler member 210 may be a common ruler or a retractable ruler, and the first position indicates the position of the 0 scale line.

[0080] The embodiment of the present application does not limit the specific structure of the abutment member 220. For example, the abutment member 220 may be an abutment plate.

[0081] In some possible implementations, in the end face measurement tool provided in the embodiment of the present application, the scale assembly 200 further includes a first scale member 240 , the first scale member 240 is connected to the abutment member 220 , and the first scale member 240 extends out of the flange.

[0082] When the guide rail 20 exceeds the flange end face 11, the guide rail 20 is located above the flange end face 11. Since the scale member 210 and the abutment member 220 are L-shaped, the abutment member 220 needs to be placed on the rear end face of the flange, and the scale member 210 extends along the second direction toward the flange end face 11. To measure the distance between the guide rail end face 21 and the flange end face 11, the thickness of the flange needs to be subtracted.

[0083] Therefore, in order to simplify the operation, the scale assembly 200 further includes a first scale member 240, which is connected to the abutment member 220 and extends out of the flange end surface 11. Exemplarily, the abutment member 220 is located between the scale member 210 and the first scale member 240. Therefore, whether the guide rail 20 exceeds or falls below the flange end surface 11, the distance between the guide rail end surface 21 and the flange end surface 11 can be measured. There is no need to adjust the position of the abutment member 220, nor to subtract the thickness of the flange, thereby simplifying the operation steps.

[0084] It should be noted that the lengths of the first scale member 240 and the scale member 210 can be adjusted according to actual conditions, and the embodiment of the present application does not limit this. Exemplarily, the length of the first scale member 240 is equal to the length of the scale member 210.

[0085] In some embodiments, in the end face measurement tool provided by the embodiments of the present application, the scale assembly 200 also includes a connector 230 , which is disposed on a side of the scale member 210 facing away from the measurement assembly 300 , and is used to connect to the inner wall of the wind turbine tower 10 .

[0086] In specific implementation, in order to facilitate the disassembly and assembly of the scale member 210 , a connector 230 is provided on the scale member 210 . The connector 230 is located on a side of the scale member 210 away from the measuring assembly 300 . The connector 230 is used to connect to the inner wall of the wind power tower 10 .

[0087] The embodiment of the present application does not limit the connection method between the connector 230 and the inner wall of the wind turbine tower 10. Exemplarily, it can be a magnet connection, a suction cup connection or a connection method to facilitate quick and stable connection or disconnection with the inner wall of the wind turbine tower 10.

[0088] In some possible implementations, in the end face measurement tool provided by the embodiment of the present application, the connecting member 230 is a magnet.

[0089] The embodiment of the present application does not specifically limit the number of the connecting members 230. For example, the number of the connecting members 230 can be one or more.
