Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a rotary positioning device and a wind turbine defect detection equipment. Background Technology

[0002] As a key component of air conditioners, the quality of the impeller has a crucial impact on the overall performance of the air conditioner. However, in actual production and transportation, the impeller blades are prone to cracks, breaks, or hidden cracks due to impacts. Therefore, defect inspection of the incoming impeller is necessary before assembly. Currently, defect inspection of the impeller requires positioning the impeller using a positioning fixture, and then inspecting each blade by rotating the impeller. However, in actual production, the size and specifications of the impellers configured in different batches may vary. When changing to inspect impellers of different sizes and specifications, the positioning fixture needs to be changed simultaneously, which requires a high level of technical skill from the operators and affects production efficiency.

[0052] The above-described one or more technical solutions in the embodiments of this utility model have at least one of the following technical effects:

[0053] By setting up a first positioning mechanism and a second positioning mechanism, a friction part and a positioning part with a conical surface are provided on the first positioning structure of the first positioning mechanism. The conical surface of the positioning part mates with the positioning hole at one end of the product to be tested, and the friction part abuts against the cross-section of one end of the product to be tested. The second positioning structure of the second positioning mechanism positions and mates with the other end of the product to be tested. The first positioning structure is driven to rotate by a drive mechanism, thereby achieving the positioning of the product to be tested. When the product to be tested is a wind turbine, the positioning hole sizes at the ends of wind turbines of different sizes are different. The conical surface can accommodate various positioning hole sizes, allowing this rotary positioning device to be used for rotary positioning of wind turbines of different sizes. This avoids the problem of needing to change the positioning fixture when changing wind turbines of different sizes for testing on the production line, thus improving production efficiency. At the same time, since the first positioning structure abuts against the end face of the wind turbine through the friction part, the friction between the friction part and the end face of the wind turbine drives the product to be tested to rotate. This means that the conical surface does not need to be tightly fitted with the positioning hole, preventing the positioning part of the first positioning mechanism from damaging the positioning hole of the wind turbine.

[0066] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0068] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0069] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0070] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0071] The rotary positioning device provided in this embodiment can be used for the rotary positioning of the fan wheel of an air conditioner to assist in the detection of defects in the fan wheel, and can also be used for the rotary positioning of other columnar structural components.

[0072] like Figure 1As shown, the rotary positioning device includes a first positioning mechanism 11 and a second positioning mechanism 12. The first positioning mechanism 11 includes a first support 111, a first positioning structure 112, and a drive mechanism 113. The first positioning structure 112 is rotatably connected to the first support 111. The drive mechanism 113 is rotatably driven connected to the first positioning structure 112. The first positioning structure 112 has a positioning part and a friction part 11221. The positioning part has a tapered surface 1121, which is adapted to mate with a positioning hole at one end of the product to be tested. The friction part 11221 is adapted to abut against the end face of the product to be tested. The second positioning mechanism 12 includes a second support 121 and a second positioning structure 122. The second positioning structure 122 is mounted on the second support 121 and is adapted to position and mate with the other end of the product to be tested. The first positioning structure 112 and the second positioning structure 122 can move closer to or further away from each other.

[0073] The product under test has a first end 51 and a second end 52 that are axially opposite each other. The first end 51 is provided with a positioning hole and an end face. The operation steps for rotating and positioning the product under test using this rotary positioning device are as follows: The first positioning structure 112 and the second positioning structure 122 are moved away from each other. The product under test is moved between the first positioning structure 112 and the second positioning structure 122, with the first end 51 facing the first positioning structure 112 and the second end 52 facing the second positioning structure 122. The first positioning structure 112 and the second positioning structure 122 are then brought closer together, so that a portion of the conical surface 1121 extends into the positioning hole and engages with it. Simultaneously, the friction part 11221 abuts against the end face of the first end 51, and the second end 52 engages with the second positioning structure 122, thus completing the positioning of the product under test. After positioning is completed, the drive mechanism 113 is activated. The drive mechanism 113 drives the first positioning structure 112 to rotate, and the first positioning structure 112 drives the product under test to rotate through the friction part 11221.

[0074] The mating structure between the second positioning structure 122 and the second end 52 of the product under test can be configured according to the specific structure of the second end 52. For example, if the second end 52 has a convex shaft, then the second positioning structure 122 has a positioning hole, and the convex shaft can be rotatably inserted into the positioning hole of the second positioning structure 122 to achieve rotational mating between the product under test and the second positioning mechanism 12. Alternatively, the second end 52 also has a positioning hole, and the positioning mating method of the positioning hole of the second end 52 and the second positioning structure 122 can be the same as the positioning mating method of the positioning hole of the first end 51 and the first positioning structure 112. In this embodiment of the present invention, the product under test can be a wind turbine 5 or other cylindrical structural components. The following embodiments are all described with the wind turbine 5 as the product under test.

[0075] The rotary positioning device provided in this embodiment of the invention comprises a first positioning mechanism 11 and a second positioning mechanism 12. The first positioning structure 112 of the first positioning mechanism 11 has a friction part 11221 and a positioning part with a conical surface 1121. The conical surface 1121 of the positioning part engages with a positioning hole at one end of the product to be tested, and the friction part 11221 abuts against the cross-section of one end of the product to be tested. The second positioning structure 122 of the second positioning mechanism 12 engages with the other end of the product to be tested. The first positioning structure 112 is driven to rotate by a driving mechanism 113, thereby achieving the positioning of the product to be tested. When the product to be tested is a wind turbine 5, the positioning hole sizes at the ends of wind turbines 5 vary depending on their size. The conical surface 1121 can accommodate various positioning holes of different sizes, allowing the rotary positioning device to be used for rotary positioning of wind turbines 5 of different sizes. This avoids the problem of needing to change positioning fixtures when changing wind turbines 5 of different sizes on the production line, thus improving production efficiency. Meanwhile, since the first positioning structure 112 abuts against the end face of the impeller 5 through the friction part 11221, the friction between the friction part 11221 and the end face of the impeller 5 drives the product to be tested to rotate, so that the conical surface 1121 does not need to be tightly fitted with the positioning hole, thus preventing the positioning part of the first positioning mechanism 11 from damaging the positioning hole of the impeller 5.

[0076] In some optional embodiments, the first positioning structure 112 includes a rotating shaft and a rotating wheel 1122. The driving end of the driving mechanism 113 is coaxially connected to the rotating shaft, and one end of the rotating shaft forms a positioning part. The rotating wheel 1122 is fixed to the rotating shaft, and a friction part 11221 is formed on the rotating wheel 1122. The driving mechanism 113 drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the rotating wheel 1122 to rotate. The friction part 11221 on the rotating wheel 1122 drives the impeller 5 to rotate.

[0077] like Figure 1 and Figure 2 As shown, in some other embodiments of this utility model, the first positioning structure 112 includes a rotating shaft, a rotating wheel 1122, a first limiting member 1123, and an elastic member 1124. The driving end of the driving mechanism 113 is coaxially connected to the rotating shaft, and one end of the rotating shaft forms a positioning part. The rotating wheel 1122 is axially movably sleeved on the rotating shaft and coaxially connected to the rotating shaft, and a friction part 11221 is formed on the rotating wheel 1122. The first limiting member 1123 is fixed to the rotating shaft and is located on the side of the rotating wheel 1122 away from the positioning part. The elastic member 1124 is located between the rotating wheel 1122 and the first limiting member 1123. Wherein, when the product to be tested is positioned between the first positioning mechanism 11 and the second positioning mechanism 12, the elastic member 1124 is pressed between the rotating wheel 1122 and the first limiting member 1123.

[0078] Understandably, a positioning portion with a tapered surface 1121 is formed at the end of the rotating shaft away from the first positioning structure 112, and a friction portion 11221 is formed on the side of the rotating wheel 1122 near the positioning portion. The positioning portion, the rotating wheel 1122, the elastic member 1124, and the first limiting member 1123 are distributed sequentially along the axial direction of the rotating shaft. The rotating wheel 1122, the elastic member 1124, and the first limiting member 1123 are fixed relative to the rotating shaft in the circumferential direction, and when the rotating shaft rotates, it drives the rotating wheel 1122, the first limiting member 1123, and the elastic member 1124 to rotate synchronously.

[0079] The first limiting member 1123 can be a shaft segment integrally formed on the rotating shaft, or a nut or limiting block threadedly connected to the rotating shaft. The elastic member 1124 can be a compression spring, gas spring, or elastic washer sleeved on the rotating shaft, etc., and can be selected according to actual needs.

[0080] With the impeller 5 positioned between the first positioning mechanism 11 and the second positioning mechanism 12, the friction part 11221 of the rotating wheel 1122 abuts against the end face of the impeller 5, and the elastic member 1124 is pressed between the rotating wheel 1122 and the first limiting member 1123. This ensures that the friction part 11221 of the rotating wheel 1122 exerts a certain pressure on the end face of the impeller 5, allowing the rotation of the rotating wheel 1122 to drive the impeller 5 to rotate. Furthermore, the axial distance between the positioning hole and the end face of impellers of different specifications may vary. In this embodiment, by elastically connecting the rotating wheel 1122 to the first limiting member 1123, the rotating wheel 1122 can be adapted to impellers of different specifications, ensuring that the friction part 11221 abuts against the end face of the impeller 5.

[0081] Furthermore, the first positioning structure 112 also includes a second limiting member 1125, which is fixed to the rotating shaft and located between the positioning part and the rotating wheel 1122. The rotating wheel 1122 can be pressed between the second limiting member 1125 and the elastic member 1124, and the elastic member 1124 is pressed between the rotating wheel 1122 and the first limiting member 1123. Thus, the rotating wheel 1122, the elastic member 1124, and the first limiting member 1123 are not fixedly connected; the second limiting member 1125 provides axial positioning of the rotating wheel 1122.

[0082] Furthermore, multiple friction posts protrude from the side of the rotor 1122 near the positioning part, forming friction parts 11221. These friction posts are evenly spaced along the circumference of the rotor 1122. It can be understood that the friction posts extend axially along the rotor 1122, and through frictional contact with the impeller 5, the volume of the rotor 1122 can be reduced, while ensuring sufficient frictional contact area between the rotor 1122 and the impeller 5. The evenly spaced distribution of the multiple friction parts 11221 around the conical surface 1121 ensures uniform force distribution on the end face of the impeller 5, which is beneficial for ensuring the stability of the impeller 5's rotation. (See also...) Figure 2 There are three friction columns, which are distributed at 120° angles to each other. In practical applications, the required number of friction columns can be determined based on the frictional torque required to drive the wind turbine to rotate.

[0083] Optionally, a buffer is provided at the end of the friction column, through which the friction column contacts the end face of the impeller 5. The buffer can be a structural component made of flexible materials such as silicone or rubber, which can both increase the friction between the friction column and the end face and prevent the friction column from damaging the end face.

[0084] like Figure 2 As shown, in some embodiments of this utility model, the drive mechanism 113 includes a first drive member 1131 and a transmission assembly. The first drive member 1131 is mounted on a first bracket 111. The transmission assembly includes a first transmission wheel 1132, a second transmission wheel 1133, and a flexible transmission member surrounding the first transmission wheel 1132 and the second transmission wheel 1133. The drive end of the first drive member 1131 is drive-connected to the first transmission wheel 1132, and the second transmission wheel 1133 is coaxially drive-connected to the first positioning structure 112. Specifically, the second transmission wheel 1133 is coaxially drive-connected to the rotating shaft of the first positioning structure 112.

[0085] The first driving component 1131 is a rotary driving component, such as an electric motor, hydraulic motor, or pneumatic motor. The first transmission wheel 1132 is coaxially connected to the rotary driving shaft of the first driving component 1131. The transmission assembly is a flexible transmission assembly, and the first and second transmission components can be pulleys, with corresponding flexible transmission components being flat belts and synchronous belts. The first and second transmission components can also be sprockets, with the corresponding flexible transmission component 1134 being a chain. The first driving component 1131 is rotaryly connected to the first positioning structure 112 via the flexible transmission assembly, which can reduce installation costs and vibration.

[0086] It should be noted that the transmission assembly in this embodiment is not limited to a flexible transmission assembly. For example, the transmission assembly can also be a gear transmission assembly. The power output shaft of the first driving member 1131 is coaxially connected to the input gear of the gear transmission assembly, and the rotating shaft of the first positioning structure 112 is coaxially connected to the output gear of the gear transmission assembly.

[0087] like Figure 3As shown, in some embodiments of this utility model, the second positioning structure 122 includes a first roller 1221, a second driving member 1223, and a second roller 1222. The two first rollers 1221 are rotatably connected to the second bracket 121 and arranged side-by-side. The convex shaft at the other end of the product under test can be supported between the two first rollers 1221. The second driving member 1223 is mounted on the second bracket 121. The second roller 1222 is rotatably connected to the driving end of the second driving member 1223 and is located above the first roller 1221. The second driving member 1223 is used to drive the second roller 1222 to move up and down. The convex shaft is adapted to be positioned between the two first rollers 1221 and the second roller 1222.

[0088] Specifically, the second driving component 1223 is a linear driving component, such as a cylinder or hydraulic cylinder, used to drive the second roller 1222 to move vertically up and down. The axes of rotation of the first roller 1221 and the second roller 1222 are parallel. The two first rollers 1221 are arranged side by side and spaced apart in the horizontal direction, forming a positioning groove between them. The convex shaft can be supported in the two positioning grooves and roll in contact with the two first rollers 1221. The second roller 1222 can be located on the symmetrical center line of the two first rollers 1221. When positioning the impeller 5, the second drive member 1223 first drives the second roller 1222 to rise, and after placing the convex shaft of the second end 52 of the impeller 5 into the positioning groove, the second drive member 1223 then drives the second roller 1222 to fall and abut against the convex shaft, so that the convex shaft is limited between the two first rollers 1221 and the second roller 1222, and the convex shaft rolls in contact with the first rollers 1221 and the second rollers 1222, thereby achieving rotational positioning of the convex shaft.

[0089] In other embodiments, the second positioning structure 122 can be a blind hole provided on the second bracket 121, and the second end 52 of the impeller 5 can be rotatably inserted into the blind hole to realize the axial positioning of the second end 52 of the impeller 5 and its rotational cooperation with the second positioning structure 122.

[0090] like Figure 2 As shown, some embodiments of the present invention provide a rotary positioning device that further includes a third driving member 114. The first bracket 111 includes a first mounting base 1111 and a first mounting frame 1112. The first positioning structure 112 is mounted on the first mounting frame 1112, and the first mounting frame 1112 is slidably mounted on the first mounting base 1111. The third driving member 114 is connected to the first mounting frame 1112 and is used to drive the first mounting frame 1112 to move closer to or away from the second positioning structure 122.

[0091] The third driving component 114 is a linear driving component, such as a cylinder or hydraulic cylinder, used to drive the first mounting bracket 1112 to slide relative to the first mounting base 1111, so that the first positioning structure 112 moves closer to or further away from the second positioning structure 122.

[0092] Specifically, the first mounting base 1111 is provided with a first guide rail or a first sliding groove, and the first mounting bracket 1112 is slidably disposed on the first guide rail or the first sliding groove. The first driving member 1131 is fixed to the first mounting bracket 1112, the transmission assembly is mounted on the first mounting bracket 1112, and the rotating shaft of the first positioning structure 112 is rotatably mounted on the first mounting bracket 1112. When the third driving member 114 pushes the first mounting bracket 1112 to slide relative to the first mounting base 1111, it causes the first positioning structure 112 to move closer to or further away from the second positioning structure 122.

[0093] like Figure 3 As shown, some embodiments of the present invention provide a rotary positioning device that further includes a fourth driving member 123. The second bracket 121 includes a second mounting base 1211 and a second mounting frame 1212. The second positioning structure 122 is mounted on the second mounting frame 1212, and the second mounting frame 1212 is slidably mounted on the second mounting base 1211. The fourth driving member 123 is connected to the second mounting frame 1212 and is used to drive the second mounting frame 1212 to move closer to or away from the first positioning structure 112.

[0094] The fourth driving component 123 is a linear driving component, such as a cylinder or hydraulic cylinder, used to drive the second mounting bracket 1212 to slide relative to the second mounting base 1211, so that the second positioning structure 122 moves closer to or further away from the first positioning structure 112.

[0095] Specifically, the second mounting base 1211 is provided with a second guide rail or a first sliding groove, and the second mounting bracket 1212 is slidably mounted on the second guide rail or the first sliding groove. The second driving member 1223 is fixed to the first mounting bracket 1112, the first roller 1221 is rotatably mounted on the second mounting bracket 1212, and the two first rollers 1221 are respectively rotatably mounted on the second mounting bracket 1212. The second driving member 1223 is fixed to the second mounting bracket, and the second roller 1222 is rotatably mounted on the driving end of the second driving member 1223. When the fourth driving member 123 pushes the second mounting bracket 1212 to slide relative to the second mounting base 1211, it causes the second positioning structure 122 to move closer to or away from the first positioning structure 112.

[0096] Optionally, the first mounting bracket 1112 is provided with a clearance groove, the first roller 1221 and the second roller 1222 are located on the side of the second mounting bracket 1212 facing the first positioning mechanism 11, and the second driving member 1223 is mounted on the side of the second mounting bracket 1212 away from the first positioning mechanism 11. The driving end of the second driving member 1223 passes through the clearance groove and is rotatably connected to the second roller 1222. The clearance groove allows the convex shaft of the impeller 5 to pass through, thus making the structure of the second positioning mechanism 12 more compact.

[0097] The rotary positioning device provided in some embodiments of this utility model includes a third driving member 114 and a fourth driving member 123. The third driving member 114 and the fourth driving member 123 can be activated simultaneously, causing the first positioning structure 112 and the second positioning structure 122 to move away from or towards each other simultaneously. When rotating and positioning the wind turbine 5, the wind turbine 5 does not need to move axially, thus avoiding interference between the first positioning structure 112, the second positioning structure 122, and the wind turbine 5. This simplifies automated positioning operations and improves positioning efficiency.

[0098] like Figure 1 As shown, the rotary positioning device provided in some embodiments of this utility model further includes a fifth driving member 13. The driving end of the fifth driving member 13 is connected to the first bracket 111 and is used to drive the first bracket 111 to move closer to or away from the second bracket 121. Alternatively, the driving end of the fifth driving member 13 is connected to the second bracket 121 and is used to drive the second bracket 121 to move closer to or away from the first bracket 111.

[0099] Optionally, the fifth driving element 13 is a linear module, and one of the first bracket 111 and the second bracket 121 is mounted on the moving end of the linear module. Alternatively, the fifth driving element 13 is a linear driving element such as a cylinder or hydraulic cylinder, and the rotary positioning device further includes a slide rail, on which the first bracket 111 or the second bracket 121 is slidably disposed. The fifth driving element 13 drives the first bracket 111 or the second bracket 121 to slide along the slide rail, so that the first bracket 111 and the second bracket 121 move closer to or further away from each other.

[0100] In this embodiment, the first support 111 or the second support 121 is moved by the fifth driving member 13, so that the first support 111 and the second support 121 move closer or further apart, which can realize a larger span adjustment of the distance between the first positioning structure 112 and the second positioning structure 122, so that the rotary positioning device can be used for positioning wind turbines 5 of more sizes and specifications, and improve the versatility of the device.

[0101] like Figure 1 As shown, this embodiment of the present invention also provides a wind turbine defect detection device, which includes a detection unit. The detection unit includes a conveying mechanism 14, a first scanning device 15, a transfer device 16, and a rotary positioning device as described in any of the above embodiments. The conveying mechanism 14 has a conveyor belt 141 for conveying the wind turbine 5. The first positioning mechanism 11 and the second positioning mechanism 12 are disposed opposite each other on both sides of the conveying direction of the conveyor belt 141. The first scanning device 15 is located on one side of the axial direction of the rotary positioning device and is used to acquire image information of the wind turbine 5 on the rotary positioning device. The transfer device 16 is used to transfer the wind turbine 5 between the conveyor belt 141 and the rotary positioning device.

[0102] It is understandable that the wind turbine 5 inspection equipment also has a processing and analysis module. The first scanning device 15 is connected to the processing and analysis module, and the processing and analysis module can determine whether there are defects in the wind turbine 5 blades based on the image information collected by the first scanning device 15.

[0103] The conveying mechanism 14 has two ends in the conveying direction that form the inlet and outlet of the detection unit. At least one first detection station is provided on the conveying path from the inlet to the outlet, and a first scanning device 15 and a transfer device 16 are provided at the first detection station. The axis of the rotary positioning device is aligned with the axis of the impeller 5 positioned thereon. When the impeller 5 rotates, the first scanning device 15 can perform a circumferential scan of the impeller 5.

[0104] When the detection unit is working, the wind turbine 5 that has arrived at the first detection station is transferred by the transfer device 16 to the first positioning structure 112 and the second positioning structure 122 of the rotary positioning device. The wind turbine 5 is rotated and positioned by the first positioning structure 112 and the second positioning structure 122. Then the drive mechanism 113 is started to drive the wind turbine 5 to rotate. At the same time, the first scanning device 15 performs image acquisition to realize the defect detection of the wind turbine 5.

[0105] Current technology primarily relies on manual visual inspection to screen for defective wind turbine components. However, different inspectors have inconsistent standards for judging defects, and workers are prone to fatigue from prolonged visual inspections. Therefore, the accuracy and reliability of the inspection are low, and there is a risk of missed defects.

[0106] This embodiment of the invention, by setting up a conveying mechanism 14, a first scanning device 15, a transfer device 16, and the rotary positioning device described in the above embodiment, allows the detection unit to operate by transferring the impeller 5 to be detected onto the conveyor belt 141 of the conveying mechanism 14 during operation. Driven by the conveyor belt 141, the impeller 5 moves from the inlet end to the outlet end. When the target impeller 5 arrives at the first detection station, the transfer device 16 transfers it to the rotary positioning device for positioning. The drive mechanism 113 is then activated to rotate the impeller 5, and the first scanning device 15 is activated to scan the impeller 5. This achieves automated, assembly-line detection of the impeller 5, improving the accuracy and reliability of the detection and significantly reducing the risk of missed detections.

[0107] Optionally, such as Figure 8 As shown, the first scanning device 15 includes multiple first visual detectors 151, which are arranged at intervals along the axial direction of the wind turbine 5. The multiple first visual detectors 151 scan multiple areas along the axial direction of the wind turbine 5. The first visual detectors 151 can be line scan cameras or TDI cameras; TDI cameras are suitable for low-light environments and have a high signal-to-noise ratio.

[0108] Further, see Figure 7 and Figure 8 The first scanning device 15 also includes a first light source 152 and a second light source 153, which are respectively located on both sides of the axial direction of the rotary positioning device. When the visual detector is a line scan camera, the first light source 152 and the second light source 153 can supplement the light to the wind turbine 5, which helps to improve the detection accuracy.

[0109] Specifically, the first visual detector 151, the first light source 152, the wind turbine 5, and the second light source 153 are arranged sequentially along a direction perpendicular to the axis of the wind turbine 5. For example... Figure 7 As shown, the second light source 153 extends along the axial direction of the impeller 5, and the first light source 152 has a first light-emitting part and a second light-emitting part extending along the axial direction of the impeller 5. A hollow part is formed between the first light-emitting part and the second light-emitting part, and a plurality of first visual detectors 151 are disposed opposite to the hollow part.

[0110] like Figure 6 As shown, in some embodiments of this utility model, the detection unit further includes a second scanning device 17. The second scanning device 17 includes at least one second visual detector 171. The second visual detector 171 is disposed on one side of the conveyor belt 141 and is used to collect image information of the end face of the wind turbine 5. The second visual detector 171 can be a line scan camera or an area scan camera, etc.

[0111] At least one second inspection station is provided on the conveying path from the feed end of the conveying mechanism 14 to the first inspection station, and a second scanning device 17 is provided on the second inspection station. The second scanning device 17 is communicatively connected to the processing and analysis module, which can determine the diameter of the end face of the impeller 5 and identify the product information of the impeller 5, such as batch number and specifications, based on the image information collected by the second scanning device 17.

[0112] When the second scanning device 17 includes two second visual detectors 171, the two visual detectors are respectively located on both sides of the conveyor belt 141 and are used to acquire images of the two end faces of the wind turbine 5 along the axial direction.

[0113] like Figure 5As shown, in some embodiments of this utility model, multiple positioning components are spaced apart along the length of the conveyor belt 141. Each positioning component includes a first positioning block 142 and a second positioning block 143 arranged opposite to each other, forming a V-shaped positioning groove between the first positioning block 142 and the second positioning block 143. The impeller 5 is placed in this positioning groove to prevent it from rolling during conveying. Further, the conveying mechanism 14 has two conveyor belts 141 spaced apart and arranged side-by-side. The positioning components on the two conveyor belts 141 are arranged one-to-one. The two ends of the impeller 5 are respectively placed in the corresponding positioning grooves on the two conveyor belts 141. The transfer device 16 can be disposed between the two conveyor belts 141.

[0114] like Figure 5 As shown, in some embodiments of this utility model, the transfer device 16 includes a lifting drive 161 and a lifting member 162, with the lifting member 162 fixed to the drive end of the lifting drive 161. The conveying mechanism 14 includes two conveyor belts 141 spaced apart, which are used to support both ends of the wind turbine 5. The lifting member is located between the two conveyor belts 141, and the first positioning structure 112 and the second positioning structure 122 are located above the conveyor belts 141. The lifting member 162 is used to lift the wind turbine 5.

[0115] Specifically, the first positioning mechanism 11 and the second positioning mechanism 12 are respectively located on opposite sides of the two conveyor belts 141. The transfer device 16 is located between the two conveyor belts 141. The lifting drive 161 is a linear drive mechanism such as a cylinder or hydraulic cylinder, used to drive the lifting member 162 to move up and down in the vertical direction.

[0116] Optionally, the support member 162 includes two spaced-apart slots, similar in structure to the positioning slots on the positioning assembly, which can be used to position the impeller 5 and prevent the impeller 5 from rolling during its movement. Alternatively, the support member 162 can be an arc-shaped plate that conforms to the shape of the impeller 5.

[0117] When the wind turbine 5 reaches the first inspection station, it is positioned directly above the lifting member 162. At this point, the lifting drive 161 drives the lifting member 162 upward, lifting the wind turbine 5 between the first positioning structure 112 and the second positioning structure 122 for positioning. After positioning, the lifting drive 161 drives the lifting member 162 downward, activating the drive mechanism 113 to rotate the wind turbine 5 and perform inspection. After inspection, the lifting drive 161 drives the lifting member 162 upward, causing the first positioning structure 112 and the second positioning mechanism 12 to move away from each other. The wind turbine 5 falls onto the lifting member 162, and the lifting drive 161 drives the lifting member 162 to continue downward, causing the wind turbine 5 to fall back onto the conveyor belt 141 and be conveyed forward with the conveyor belt 141.

[0118] It should be noted that the transfer device 16 is not limited to the above-described structural form. For example, the transfer device 16 may include two robotic arms, which are used to grab the two ends of the wind turbine 5 to realize the transfer of the wind turbine 5.

[0119] like Figure 4 As shown, the wind turbine defect detection device provided in some embodiments of this utility model includes a detection module 100, a receiving module 200, a first transfer mechanism 41, and a second transfer mechanism 42. The detection module 100 includes a first detection line and a second detection line distributed from bottom to top, both of which include detection units. The receiving module 200 is located on the discharge side of the detection module 100 and includes a first conveying mechanism 21, a second conveying mechanism 22, and a third conveying mechanism 23 distributed from bottom to top. The first transfer mechanism 41, located on the discharge side of the first detection line, is used to transfer the wind turbines 5 on the first detection line onto the first conveying mechanism 21 and the second conveying mechanism 22. The second transfer mechanism 42, located on the discharge side of the second detection line, is used to transfer the wind turbines 5 on the second detection line onto the second conveying mechanism 22 and the third conveying mechanism 23.

[0120] Specifically, the detection module 100 includes upper and lower support frames 10. The lower support frame 10 is equipped with a detection unit, forming a first detection line; the upper support frame 10 is equipped with a detection unit, forming a second detection line. The conveying mechanism 14, rotary positioning device, first scanning device 15, transfer device 16, and second scanning device 17 of the detection unit are respectively mounted on the support frame 10. The receiving module 200 has three conveyor lines: a second conveyor 22 located in the middle for receiving defective impellers 5 detected by the first and second detection lines; a first conveyor 21 for receiving qualified impellers 5 from the first detection line; and a third conveyor 23 for receiving qualified impellers 5 from the second detection line.

[0121] This embodiment of the utility model, by setting up a detection module 100 with upper and lower detection lines and a receiving module 200 with upper and lower three conveyor lines, can realize synchronous detection of the two detection lines, thereby improving detection efficiency; at the same time, the first transfer mechanism 41 and the second transfer mechanism 42 are used to classify the wind turbines 5 that have completed the detection on the two detection lines respectively, and the unqualified wind turbines 5 can be uniformly summarized into one conveyor line, thereby reducing the size of the equipment.

[0122] See Figure 4In some embodiments of this utility model, the first transfer mechanism 41 and the second transfer mechanism 42 include a first lifting drive 421 and a pickup 422. The first lifting drive 421 of the first transfer mechanism 41 is located on the discharge side of the detection line, and the first lifting drive 421 of the second transfer mechanism 42 is located on the discharge side of the second detection line. The pickup 422 includes a lifting frame 4221, a guide plate 4222, a stop plate 4223, and a stop drive. The lifting frame 4221 is fixed to the lifting end of the first lifting drive 421, and the guide plate 4222 is connected to the lifting frame 4221 and is inclined downward relative to the horizontal surface in the direction towards the receiving module 200. The stop drive is fixed to the lifting frame 4221, and the driving end of the stop drive is connected to the stop plate 4223 for driving the stop plate 4223 to switch between a first position close to the guide plate 4222 and a second position away from the guide plate 4222.

[0123] When the stop plate 4223 is in the first position, a receiving groove for accommodating the impeller 5 is formed between the stop plate 4223 and the guide plate 4222. When the stop plate 4223 is in the second position, the impeller 5 in the receiving groove can roll away from the pickup member 422 along the guide plate 4222.

[0124] The first lifting drive 421 drives the pickup 422 to move up and down between the discharge end of the detection module 100 and the feed end of the receiving module 200. The pickup 422 is used to pick up the impeller 5 output from the first or second detection line and transfer the impeller 5 to the first conveying mechanism 21, the second conveying mechanism 22 or the third conveying mechanism 23.

[0125] Specifically, the first lifting drive component 421 of the first transfer mechanism 41 can be installed at the bottom of the lower support frame 10 of the detection module 100, and the first lifting drive component 421 of the second transfer mechanism 42 can be installed at the top of the upper support frame 10 of the detection module 100, so as to avoid structural interference between the first transfer mechanism 41 and the second transfer mechanism 42. The first lifting drive component 421 and the stop drive component are linear drive components, not limited to cylinders, hydraulic cylinders, and linear modules.

[0126] The first lifting drive 421 of the first transfer mechanism 41 drives the pickup 422 to move between the discharge end of the conveying mechanism 14 of the first inspection line, the feed end of the first conveying mechanism 21, and the feed end of the second conveying mechanism 22, so as to transfer the qualified impellers 5 detected on the first inspection line to the first conveying mechanism 21, and the unqualified impellers 5 to the second conveying mechanism 22. The first lifting drive 421 of the second transfer mechanism 42 drives the pickup 422 to move between the discharge end of the conveying mechanism 14 of the second inspection line, the feed end of the second conveying mechanism 22, and the feed end of the third conveying mechanism 23, so as to transfer the qualified impellers 5 detected on the second inspection line to the third conveying mechanism 23, and the unqualified impellers 5 to the second conveying mechanism 22.

[0127] Understandably, the guide plate 4222 of the pickup component 422 is inclined relative to the horizontal plane, and its end near the detection module 100 is higher than its end near the receiving module 200. When a fan wheel 5 arrives at the discharge end of the conveying mechanism 14, the first lifting drive component 421 drives the pickup component 422 to move to the discharge end and switches the stop plate 4223 to the first position. The fan wheel 5 output by the conveying mechanism 14 rolls into the receiving groove of the pickup component 422 under the action of gravity, thus picking up the fan wheel 5. Then, the first lifting drive component 421 drives the pickup component 422 to move to the feeding end of a conveying mechanism and switches the stop plate 4223 to the second position, so that the fan wheel 5 can roll along the guide plate 4222 onto the conveying mechanism, completing the transfer of the fan wheel 5.

[0128] It should be noted that the specific structural forms of each component of the first transfer mechanism 41 and each component of the second transfer mechanism 42 may be the same or different, and can be adjusted according to actual needs or installation space. This embodiment does not limit the structure of the first transfer mechanism 41 and the second transfer mechanism 42 to be exactly the same.

[0129] It should be noted that the first transfer mechanism 41 and the second transfer mechanism 42 are not limited to the above-mentioned structural forms. For example, both the first transfer mechanism 41 and the second transfer mechanism 42 include two robotic arms, which are used to grab the two ends of the wind turbine 5 to realize the transfer of the wind turbine 5.

[0130] like Figure 4As shown, the wind turbine defect detection equipment provided in some embodiments of this utility model also includes a feeding module 300. The feeding module 300 is located on the feeding side of the detection module 100 and includes a fourth conveying mechanism 31 and a fifth conveying mechanism 32 distributed from bottom to top. A first detection line is used to receive the wind turbine 5 from the fourth conveying mechanism 31, and a second detection line is used to receive the wind turbine 5 from the fifth conveying mechanism 32. It can be understood that the feeding module 300 has upper and lower conveying lines; the wind turbine 5 from the fourth conveying mechanism 31 is conveyed to the conveying mechanism 14 of the first detection line, and the wind turbine 5 from the fifth conveying mechanism 32 is conveyed to the conveying mechanism 14 of the second detection line. This feeding module 300 enables long-distance feeding of the detection module 100.

[0131] In some embodiments of this utility model, the fourth conveying mechanism 31 may be slightly higher than the conveying mechanism 14 of the first detection line, so that the impeller 5 on the fourth conveying mechanism 31 can automatically fall onto the conveying mechanism 14 of the first detection line. The fifth conveying mechanism 32 may be slightly higher than the conveying mechanism 14 of the first detection line, so that the impeller 5 on the fifth conveying mechanism 32 can automatically fall onto the conveying mechanism 14 of the second detection line.

[0132] In other embodiments of this utility model, the wind turbine defect detection device further includes a third transfer mechanism 43. For example... Figure 4 As shown, the third transfer mechanism 43 is located on the feeding side of the first detection line and is used to transfer the impeller 5 on the fourth conveying mechanism 31 to the conveying mechanism 14 of the first detection line.

[0133] Optionally, the discharge end of the fourth conveying mechanism 31 is located above the feed end of the first detection line. The conveying mechanism 14 includes two horizontally spaced conveyor belts 141, which are used to support both ends of the impeller 5. The third transfer mechanism 43 includes a second lifting drive and a receiving component 431. The second lifting drive is located on the feed side of the first detection line. The receiving component 431 is fixed to the lifting end of the second lifting drive, which drives the receiving component 431 to move up and down between the two conveyor belts 141. The receiving component 431 is used to receive the impeller 5 output by the third conveying mechanism 23.

[0134] The second lifting drive component can be installed at the bottom of the lower support frame 10 of the detection module 100. The second lifting drive component is a linear drive component, not limited to cylinders and linear modules.

[0135] When a fan wheel 5 reaches the discharge end of the fourth conveying mechanism 31, the second lifting drive drives the receiving component 431 to move to the discharge end. The fan wheel 5 output by the fourth conveying mechanism 31 rolls onto the receiving component 431 under gravity, thus picking up the fan wheel 5. Then, the second lifting drive drives the receiving component 431 to move downwards towards the conveying mechanism 14, so that the two conveyor belts 141 of the conveying mechanism 14 receive the two ends of the fan wheel 5. After the fan wheel 5 moves forward, the second lifting drive drives the receiving component 431 to rise to the discharge end of the fourth conveying mechanism 31, waiting for the next fan wheel 5 to be output. This embodiment can achieve a compact arrangement of the fourth conveying mechanism 31 and the first detection line, reducing the space occupied by the equipment, and the height of the fourth conveying mechanism 31 can be flexibly set, so that the fourth conveying mechanism 31 can meet the loading operations at different heights.

[0136] It should be noted that if the distance between the fourth conveying mechanism 31 and the conveying mechanism 14 of the first detection line in the conveying direction is large enough, the third moving mechanism can be set to the same structure as the first moving mechanism, for example, the wind turbine 5 can be moved by the picking member 422.

[0137] See Figure 4 Furthermore, the receiving component 431 includes a base 4311, a first side plate 4312, and a second side plate 4313. The base 4311 is fixed to the lifting end of the second lifting drive component. The first side plate 4312 and the second side plate 4313 are respectively connected to both sides of the base 4311 and are arranged opposite to each other in the conveying direction of the conveying mechanism 14. The first side plate 4312 is inclined from the base 4311 in a direction away from the second side plate 4313, and the second side plate 4313 is inclined from the base 4311 in a direction away from the first side plate 4312. The inclination angle of the first side plate 4312 is greater than the inclination angle of the second side plate 4313.

[0138] The base 4311, the first side plate 4312, and the second side plate 4313 all extend along a direction perpendicular to the conveying direction of the impeller 5. The first side plate 4312, the second side plate 4313, and the base 4311 form a V-shaped groove. The impeller 5 on the fourth conveying mechanism 31 rolls into this V-shaped groove along the first side plate 4312, thus positioning the impeller 5 and preventing it from rolling during transfer. The first side plate 4312 has a smaller inclination angle, which reduces the impact between the impeller 5 and the receiving part 431 when it rolls into the V-shaped groove; the second side plate 4313 has a larger inclination angle, which effectively prevents the impeller 5 from rolling out of the V-shaped groove.

[0139] Optionally, both the first side plate 4312 and the second side plate 4313 are provided with buffers on the side facing the V-groove to avoid rigid impact between the receiving part 431 and the impeller 5. Buffers can also be provided on the surfaces of the positioning assembly and the lifting part 162 in the above embodiments that are in contact with the impeller 5.

[0140] In some embodiments of this invention, the height difference between the fifth conveying mechanism 32 and the conveying mechanism 14 of the second inspection line is significant. For example, the height of the fifth conveying mechanism 32 is lower than the height of the conveying mechanism 14 of the second inspection line to facilitate manual loading. To address this, the wind turbine defect detection device also includes a fourth transfer mechanism 44. The fourth transfer mechanism 44 is located at the feed end of the second inspection line and is used to transfer the wind turbine 5 from the fifth conveying mechanism 32 to the conveying mechanism 14 of the second inspection line. The structure of the fourth transfer mechanism 44 is the same as that of the second transfer mechanism 42.

[0141] The first lifting drive 421 of the fourth transfer mechanism 44 can be installed on the top of the upper support frame 10 of the detection module 100. When a fan wheel 5 reaches the discharge end of the fifth conveying mechanism 32, the first lifting drive 421 of the fourth transfer mechanism 44 drives the corresponding picking member 422 to move to the discharge end and switches the stop plate 4223 to the first position. The fan wheel 5 output by the fifth conveying mechanism 32 rolls into the receiving groove of the picking member 422 under the action of gravity, realizing the picking of the fan wheel 5. Then, the first lifting drive 421 drives the picking member 422 to move to the feeding end of the conveying mechanism 14 of the second detection line and switches the stop plate 4223 to the second position, so that the fan wheel 5 can roll along the guide plate 4222 onto the conveying mechanism 14, completing the transfer of the fan wheel 5.

[0142] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
