However, due to the large size of the wind turbine blades and the different sizes of different specifications of the wind turbine blades, how to make wind turbine blades of different specifications smoothly pass through the scanning area of the scanning equipment becomes a difficult problem to be solved. SUMMARY

At the same time, it has the advantages of simple structure, flexible and convenient use, low cost, and low maintenance cost. In addition, it can flexibly adapt to the requirements of different scanning modes (such as DR scanning and CT scanning) for the conveying speed.

[0004] The first aspect of the present disclosure provides a conveying device for wind turbine blade scanning, comprising: a driving transmission device, the driving transmission device comprising a main driving member and a main vehicle body member, the main vehicle body member being provided with a first mounting portion adapted to fixedly mount a first end of a wind turbine blade; and a driven transmission device, the driven transmission device being provided with a second mounting portion adapted to fixedly mount a second end of the wind turbine blade; when the driving transmission device moves, it drives the wind turbine blade and the driven transmission device to move, so that the wind turbine blade passes through the scanning area of the scanning equipment. Wherein, the main vehicle body member comprises: a carrier component, the carrier component being connected with the main driving member, so that the main driving member drives the carrier component to move at a first set speed; and a micro-motion component, the micro-motion component being movably arranged on the carrier component, when the carrier component stops moving, the micro-motion component drives the wind turbine blade and the driven transmission device to move at a second set speed.

[0005] The conveying device for fan blade scanning according to the embodiment of the present disclosure can convey the fan blade through the scanning area of the scanning device at the first or second set speed by the driving transmission device and the driven transmission device, so that the fan blade can be checked by the scanning device. When the conveying device of the present disclosure conveys the fan blade for scanning, the driving transmission device can drive the fan blade and the driven transmission device to move, so that only the driving transmission device needs to be driven by the power source, and the driven transmission device does not need to be driven by the power source, thereby saving energy. In addition, the driving transmission device and the driven transmission device are separately arranged, and are connected by the fan blade when conveying the fan blade, so that the driving transmission device drives the driven transmission device to move. If the driving transmission device and the driven transmission device are not separately arranged, but are arranged as a whole to convey the fan blade, only the fan blade of a fixed specification can be conveyed, and the driving transmission device and the driven transmission device that are not separately arranged do not have universality. The driving transmission device and the driven transmission device of the present disclosure are separately arranged, and the relative set position between the two can be determined according to the specification of the fan blade, so that the fan blade of different specifications can be connected between the driving transmission device and the driven transmission device, thereby facilitating the smooth passing of the fan blade of different specifications through the scanning area of the scanning device. In addition, by arranging the carrier component and the micro-motion component, the conveying device can flexibly adapt to the requirement of conveying speed of different scanning modes (such as DR scanning and CT scanning).

When the conveying device of the present disclosure conveys the fan blade for scanning, the driving transmission device can drive the fan blade and the driven transmission device to move, so that only the driving transmission device needs to be driven by energy, and the driven transmission device does not need to be driven by energy, thereby saving energy. In addition, the driving transmission device and the driven transmission device are separately arranged, and are connected by the fan blade when conveying the fan blade, so that the driving transmission device drives the driven transmission device to move. If the driving transmission device and the driven transmission device are not separately arranged, but are conveyed as a whole, only fan blades of fixed specifications can be conveyed, and the driving transmission device and the driven transmission device that are not separately arranged do not have universality. The driving transmission device and the driven transmission device of the present disclosure are separately arranged, and the relative set position between the two can be determined according to the specifications of the fan blade, so that fan blades of different specifications can be connected between the driving transmission device and the driven transmission device, thereby facilitating the smooth passing of fan blades of different specifications through the scanning area of the scanning device. In addition, by arranging the carrier component and the micro-motion component, the conveying device can flexibly adapt to the requirement of conveying speed of different scanning modes (such as DR scanning and CT scanning). If the carrier component and the micro-motion component are not combined, only fan blades can be conveyed at the same speed, and the fan blades cannot adapt to different scanning modes. At the same time, the conveying device of the present disclosure has simple structure, flexible and convenient use, low cost, and low maintenance cost.

[0015] In some embodiments, the scanning device comprises a DR scanning device configured to scan the fan blade as a whole to obtain a scanning result, wherein the scanning result is abnormal or normal; and a CT scanning device configured to scan an abnormal part of the fan blade with the abnormal scanning result.

[0031] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It is to be understood, however, that the description is merely exemplary and is not intended to limit the scope of the present disclosure. Also, in the following description, descriptions of well-known functions and constructions are omitted to avoid obscuring the concept of the present disclosure in unnecessary detail. In addition, various embodiments provided below and technical features in the embodiments can be combined in any manner.

[0032] The terms used herein are merely used to describe specific embodiments, and are not intended to limit the present disclosure. In addition, the terms "include", "comprise" and the like used herein mean the presence of the described features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components. All terms used herein, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of the specification, and should not be interpreted in an idealized or overly formal manner.

[0033] Reference will now be made to Figures 1-5 a conveying apparatus 100 for fan blade scanning, a fan blade scanning system, and a fan blade scanning method according to embodiments of the present disclosure are described.

[0034] As Figures 1-4 shown, a conveying apparatus 100 for fan blade scanning according to an embodiment of the present disclosure includes a driving transmission device 1 and a driven transmission device 2.

[0035] Specifically, in conjunction with Figures 1-4The active transmission device 1 may include a main drive component and a main body component 11. The main body component 11 is connected to the main drive component so that the main drive component drives the main body component 11 to move. The main body component 11 has a first mounting portion suitable for fixing a first end of the fan blade 200. The driven transmission device 2 has a second end suitable for fixing the fan blade 200. When the active transmission device 1 moves, it drives the fan blade 200 and the driven transmission device 2 to move so that the fan blade 200 passes through the scanning area of ​​the scanning device. For example, the first end may be the root of the fan blade 200, and the second end may be the tail of the fan blade 200. The first mounting portion may be a root support frame of the fan blade (not shown).

[0036] Among them, such as Figure 1 As shown, the main body component 11 includes a carrier component 111 and a micro-motion component 112. The carrier component 111 is connected to the main drive component, so that the main drive component drives the carrier component 111 to move at a first set speed. The micro-motion component 112 is movably disposed on the carrier component 111, and the first end of the fan blade 200 is adapted to be fixedly mounted on the micro-motion component 112. When the carrier component 111 stops moving, the micro-motion component 112 drives the fan blade 200 and the driven transmission device 2 to move at a second set speed. Here, the first set speed can be a transport speed suitable for effective DR scanning of the fan blade, and the second set speed can be a transport speed suitable for effective CT scanning of the fan blade. Generally, the first set speed is greater than the second set speed.

[0037] It should be noted that, in order to improve inspection quality and efficiency, DR scanning and CT scanning are usually performed on the wind turbine blades 200mm, combined with... Figure 3 During DR scanning, the fan blades 200 need to pass quickly through the scanning area of ​​the DR scanning equipment at a first set speed. At this time, the micro-motion component 112 is stationary relative to the carrier component 111, and the main drive component drives the carrier component 111 to move at the first set speed. The carrier component 111 drives the micro-motion component 112 and the fan blades 200 to move at the first set speed, so that the fan blades 200 can pass quickly through the scanning area of ​​the DR scanning equipment at the first set speed. When the DR scan result is normal, the fan blades 200 pass the inspection.

[0038] When the DR scan results show abnormalities, a CT scan is required on the abnormal area of ​​the wind turbine blade 200, combined with... Figure 4When the CT scanning is performed, the fan blade 200 needs to pass through the scanning area of the CT scanning device at a second set speed, i.e. a slow speed of micro-motion. In this case, the main driving member drives the carrier component 111 to transport the abnormal part of the fan blade with abnormal scanning result to a stop position at a set distance in front of the scanning area of the CT scanning device. For example, when a sensor (not shown) detects that the distance between the scanning area of the CT scanning device and the abnormal part of the fan blade with abnormal scanning result is the set distance, the main driving member stops driving the carrier component 111 accordingly. Subsequently, the micro-motion component 112 moves relative to the carrier component 111, and the micro-motion component 112 drives the fan blade 200 and the driven transmission device 2 to move at the second set speed, so that the fan blade 200 can pass through the scanning area of the CT scanning device at the second set speed, i.e. the slow speed of micro-motion.

[0039] In some examples, the main driving member can be an electric motor, and the power source of the micro-motion component 112 can be an electric motor. When the carrier component 111 moves at the first set speed and the micro-motion component 112 is stationary relative to the carrier component 111, the main driving member is powered on, and the power source of the micro-motion component 112 is powered off; when the carrier component 111 is stationary and the micro-motion component 112 moves relative to the carrier component 111 at the second set speed, the main driving member is powered off, and the power source of the micro-motion component 112 is powered on.

[0040] Therefore, the conveying device 100 can be flexibly adapted to the requirements of conveying speed of different scanning modes (e.g. DR scanning and CT scanning) by the carrier component 111 and the micro-motion component 112.

[0041] It can be understood that, before leaving the factory or during maintenance, the fan blade needs to be scanned by a scanning device to check the fan blade and find surface and internal volumetric defects such as pores, inclusions, cracks and the like, so as to reduce the risk of failure of the fan blade. However, due to the large volume of the fan blade and the different volumes of different specifications of the fan blade, how to make different specifications of the fan blade pass through the scanning area of the scanning device smoothly becomes a difficult problem to be solved.

[0042] According to the conveying device 100 for fan blade scanning of the embodiments of the present disclosure, the fan blade 200 can be conveyed through the scanning area of the scanning device at different first or second set speeds by the driving transmission device 1 and the driven transmission device 2, so that the fan blade 200 can be subjected to the inspection of the scanning device. When the conveying device of the present disclosure conveys the fan blade for scanning, the driving transmission device 1 can drive the fan blade 200 and the driven transmission device 2 to move, so that only the driving transmission device 1 needs to be driven by energy, and the driven transmission device 2 does not need to be driven by energy, thereby saving energy. In addition, the driving transmission device 1 and the driven transmission device 2 are separately arranged, and are connected by the fan blade 200 when conveying the fan blade 200, so that the driving transmission device 1 drives the driven transmission device 2 to move. If the driving transmission device and the driven transmission device are not arranged separately, but are arranged in an integral manner to convey the fan blade, only fan blades of a fixed specification can be conveyed, and the driving transmission device and the driven transmission device that are not arranged separately do not have universality. The driving transmission device 1 and the driven transmission device 2 arranged separately according to the present disclosure can be adjusted according to the specification of the fan blade 200, so that fan blades 200 of different specifications can be connected between the driving transmission device 1 and the driven transmission device 2, thereby facilitating the smooth passing of fan blades 200 of different specifications through the scanning area of the scanning device. In addition, by arranging the carrier component 111 and the micro-motion component 112, the conveying device 100 can flexibly adapt to the requirements of different scanning modes (such as DR scanning and CT scanning) for conveying speed. If the carrier component and the micro-motion component are not combined, only fan blades can be conveyed at the same speed, and the fan blades cannot adapt to different scanning models. At the same time, the conveying device 100 of the present disclosure has a simple structure, is flexible and convenient to use, has low manufacturing cost, and has low maintenance cost.

[0043] According to some embodiments of the present disclosure, the micro-motion component 112 can include a driving part, a lead screw, and a first mounting part. The driving part is a power source of the micro-motion component 112 and is arranged on the carrier component 111. The lead screw is connected with the driving part, and the driving part drives the lead screw to rotate. The first mounting part is movably arranged on the lead screw, and when the lead screw rotates, the first mounting part can move relative to the lead screw. The first end of the fan blade 200 is adapted to be fixedly installed on the first mounting part, and when the lead screw rotates, the first mounting part drives the fan blade 200 and the driven transmission device 2 to move at the second set speed. Thus, the driving part, the lead screw, and the first mounting part can facilitate the realization of the micro-motion component 112 driving the fan blade 200 and the driven transmission device 2 to move at the second set speed. In some embodiments, the first mounting part is used in cooperation with the lead screw via a nut.

[0044] According to some embodiments of the present disclosure, the driving part can be a servo motor. It can be understood that the servo motor can facilitate the realization of driving the lead screw to move.

[0045] According to some embodiments of the present disclosure, the micro-motion component 112 can include a linear guide rail or a gear rack, etc. which can realize the micro-motion of the fan blade 200.

[0046] According to some embodiments of the present disclosure, as shown in Figure 1 The carrier component 111 can include a first wheel set 1111 and a carrier part 1112. The first wheel set 1111 is connected with the main drive component, so that the main drive component drives the first wheel set 1111 to move; the carrier part 1112 is connected with the first wheel set 1111, and the micro-motion component 112 is movably arranged on the carrier part 1112. Thus, the movement of the carrier component 111 can be facilitated by the first wheel set 1111 and the carrier part 1112.

[0047] According to some embodiments of the present disclosure, the main drive component can be a reduction motor, which can facilitate the driving of the carrier component 111 to move the micro-motion component 112 and the fan blade 200 at a first set speed.

[0048] According to some embodiments of the present disclosure, as shown in Figure 2 The driven transmission device 2 includes a support component 21 and a clamping component 22 (an example of a second mounting part). The support component 21 includes a support part 211 and a second wheel set 212, and the support part 211 is connected with the second wheel set 212; the clamping component 22 is arranged on the support part 211, and the clamping component 22 is used to clamp the second end of the fan blade 200. The second wheel set 212 can facilitate the driven movement of the driven transmission device 2 with the driving transmission device 1, the support part 211 can facilitate the arrangement of the clamping component 22, and the clamping component 22 can facilitate the fixed installation of the fan blade 200 on the driven transmission device 2.

[0049] According to some embodiments of the present disclosure, as shown in Figure 2 The clamping component 22 can include a base 221 and a clamping jaw 222. The base 221 is arranged on the support part 211; the clamping jaw 222 is connected with the base 221, and the clamping jaw 222 is used to clamp the second end of the fan blade 200. Thus, the clamping component 22 can be arranged on the support part 211 by the base 221 and the clamping jaw 222, and the fan blade 200 can be clamped.

[0050] According to some embodiments of the present disclosure, the conveying device 100 for fan blade scanning can further include a track, the track is laid in the scanning area, and the driving transmission device 1 and the driven transmission device 2 are rollably arranged on the track. For example, the first wheel set 1111 and the second wheel set 212 are rollably arranged on the track. Thus, the friction of the movement of the driving transmission device 1 and the driven transmission device 2 can be reduced, and the driving transmission device 1 and the driven transmission device 2 can facilitate the smooth passing of the fan blade 200 through the scanning area.

[0051] The fan blade scanning system according to the embodiments of the present disclosure comprises a conveying device 100 for fan blade scanning and a scanning device. The conveying device 100 for fan blade scanning is the conveying device 100 for fan blade scanning described above; the scanning device is used for scanning the fan blade 200 conveyed by the conveying device 100.

[0052] The fan blade scanning system according to the embodiments of the present disclosure can transmit the fan blade 200 through the scanning area of the scanning device at different first set speeds or second set speeds through the driving transmission device 1 and the driven transmission device 2, so that the fan blade 200 can be subjected to the inspection of the scanning device. When the conveying device of the present disclosure conveys the fan blade for scanning, the driving transmission device 1 can drive the fan blade 200 and the driven transmission device 2 to move, so that only the driving transmission device 1 needs to be driven by energy, and the driven transmission device 2 does not need to be driven by energy, thereby saving energy. In addition, the driving transmission device 1 and the driven transmission device 2 are separately arranged, and are connected by the fan blade 200 when conveying the fan blade 200, so that the driving transmission device 1 drives the driven transmission device 2 to move. If the driving transmission device and the driven transmission device are not arranged separately, but are arranged in an integral manner to convey the fan blade, only fan blades of fixed specifications can be conveyed, and the driving transmission device and the driven transmission device that are not arranged separately do not have universality. The driving transmission device 1 and the driven transmission device 2 arranged separately according to the present disclosure can be adjusted according to the specifications of the fan blade 200, so that fan blades 200 of different specifications can be connected between the driving transmission device 1 and the driven transmission device 2, thereby facilitating the smooth passing of fan blades 200 of different specifications through the scanning area of the scanning device. In addition, by arranging the carrier component 111 and the micro-motion component 112, the conveying device 100 can flexibly adapt to the requirements of different scanning modes (such as DR scanning and CT scanning) on conveying speed. If the carrier component and the micro-motion component are not combined, only fan blades can be conveyed at the same speed, and the fan blades cannot adapt to different scanning models. At the same time, the conveying device 100 of the present disclosure has simple structure, flexible and convenient use, low cost, and low maintenance cost.

[0053] According to some embodiments of the present disclosure, the scanning device can comprise a DR scanning device and a CT scanning device. The DR scanning device is used for overall scanning of the fan blade to obtain a scanning result, wherein the scanning result is abnormal or normal; and the CT scanning device is used for local scanning of the abnormal part of the fan blade with the abnormal scanning result. In this way, the inspection quality and efficiency of the fan blade 200 can be improved.

[0054] According to some embodiments of the present disclosure, the DR scanning device and the CT scanning device can be an integrated device, the integrated device has a scanning channel, the scanning channel has an entrance and an exit. The active transmission device 1 and the driven transmission device 2 transport the fan blade 200 from the entrance into the scanning channel to perform the DR scanning, here, the movement direction of the active transmission device 1 from the entrance into the scanning channel is defined as the positive direction, at this time, the CT scanning function is not started, when the DR scanning result is normal, the active transmission device 1 and the driven transmission device 2 transport the fan blade 200 from the exit out of the scanning channel; when the DR scanning result is abnormal, the active transmission device 1 switches to the reverse direction movement, and the driven transmission device 2 transports the fan blade 200 from the entrance out of the scanning channel, after exiting the scanning channel, the active transmission device 1 switches to the positive direction movement, and the driven transmission device 2 transports the fan blade 200 from the entrance into the scanning channel again to perform the CT scanning, at this time, the main driving part drives the carrier part 111 to transport the abnormal part of the fan blade 200 with the abnormal result to a scanning area of the CT scanning device and stop at a set distance in front of the scanning area. Subsequently, the micro-motion part 112 moves relative to the carrier part 111, and the micro-motion part 112 drives the fan blade 200 and the driven transmission device 2 to move at a second set speed, so that the fan blade 200 can pass through the scanning area of the CT scanning device at the second set speed, i.e., the micro-motion speed.

[0055] According to some embodiments of the present disclosure, when the active transmission device 1 switches to the reverse direction movement, the active transmission device 1 and the driven transmission device 2 transport the fan blade 200 to stop at a set distance in front of the CT scanning area without exiting the scanning channel. Subsequently, the micro-motion part 112 drives the fan blade 200 and the driven transmission device 2 to move through the CT scanning area at a second set speed, after the CT scanning is completed, the active transmission device 1 switches to the positive direction movement, and the driven transmission device 2 transports the fan blade 200 to continue the DR scanning.

[0056] Here, a first reference point can be set in the scanning area of the CT scanning device, the abnormal part can be a local range, and a second reference point can be set in the local range. The set distance can be understood as the distance from the first reference point to the second reference point.

[0057] According to some embodiments of the present disclosure, the scanning device can be a separate spiral CT device. When performing the DR scanning, the accelerator and the detector relatively arranged on the circular arm support do not rotate and are stationary in the scanning channel; when performing the CT scanning, the circular arm support rotates to drive the accelerator and the detector to rotate, so as to perform the spiral CT scanning on the abnormal part of the fan blade 200.

[0058] As Figure 5As shown, the scanning method of the fan blade according to the embodiment of the present disclosure is used for the fan blade scanning system as above, and the scanning method comprises operations S210-S270.

[0059] In operation S210, the micro-motion component is fixed to the carrier component, and the main driving component drives the carrier component to move at a first set speed.

[0060] In operation S220, the carrier component drives the micro-motion component and the fan blade to move at the first set speed, so that the fan blade passes through the scanning area of the DR scanning device at the first set speed.

[0061] In operation S230, the DR scanning device performs overall scanning on the fan blade to obtain a DR scanning result, wherein the DR scanning result is abnormal or normal.

[0062] In operation S240, when the DR scanning result is normal, the fan blade passes the inspection;

[0063] In operation S250, when the DR scanning result is abnormal, the main driving component drives the carrier component to transport the abnormal part of the fan blade with the abnormal DR scanning result to stop at a set distance in front of the scanning area of the CT scanning device.
