Description

Technical Field

[0001] The present application relates to the technical field related to wind turbine blade detection, and in particular to a blade surface UT detection device. Background Art

[0002] As a core component of a wind turbine generator system, the health of wind turbine blades is directly related to the stable operation of the entire system. If internal defects in blades, such as cracks, delamination, and debonding, are not discovered and addressed promptly, they can lead to serious accidents such as blade breakage or detachment, posing a significant threat to the safety of wind farms. Therefore, ultrasonic testing (UT) equipment is required for blade surface testing. UT testing can detect these potential defects in advance, allowing measures to be taken for repair or replacement, thereby effectively preventing major accidents. Existing UT testing equipment on the market generally uses an AGV to move along a preset path across the surface of the wind turbine blade. Its position is precisely controlled by a navigation system. Once it reaches the appropriate position, a lifting mechanism controls the height of the ultrasonic testing mechanism. The extension mechanism adjusts the lateral position of the ultrasonic testing mechanism to adapt to different locations on the blade surface. The ultrasonic probe on the ultrasonic testing mechanism then emits high-frequency ultrasonic waves and receives the reflected signals. Signal analysis determines whether there are defects within the blade, completing the inspection. For example, the detection principle disclosed in Application No. 202420837761.1, a blade surface UT testing device. During the UT inspection of the blades mentioned above, the ultrasonic inspection mechanism will need to use the cooperation of cables when working, and the coupling agent spraying system will need to use the cooperation of water pipes when spraying coupling agent, and the vacuum suction work of the air pipe will also be involved in the entire device. The above-mentioned water pipes, air pipes and cables will all change with the position of the ultrasonic inspection mechanism. Therefore, it is very easy for the pipes and cables to become entangled with each other when the equipment moves and the ultrasonic inspection mechanism is adjusted. This will not only hinder the operation of the equipment, but also affect the normal inspection work of the entire device, causing the probe to be unable to move accurately along the predetermined path, thereby affecting the inspection accuracy. In addition, the entangled pipes and cables may be excessively pulled during the operation of the equipment, resulting in pipe rupture or cable breakage. For example, a ruptured pipe in the spray system will cause the coupling agent to leak, pollute the inspection environment, and affect the inspection effect; a broken cable will cause signal transmission to be interrupted, making the inspection equipment unable to work properly.

[0031] One of the preferred embodiments of this application is as follows: Figures 1 to 12 As shown, a blade surface UT detection device includes an AGV trolley 1, a fixed frame 2 is fixed at the middle position of the top of the AGV trolley 1, a lifting detection component 3 is arranged in the middle of the fixed frame 2, and the lifting detection component 3 is driven to lift by a suspension mechanism 13, and the suspension mechanism 13 is symmetrically arranged in two groups at the top of the AGV trolley 1, the top of the lifting detection component 3 is connected to the connecting seat 4, a fixed seat 5 is arranged at the middle position of the top of the connecting seat 4, and rotating rods 6 are arranged on both sides of the fixed seat 5, and the top of the rotating rod 6 is connected to the limit fixing mechanism 7 through an angle adjustment mechanism 11, and a movable moving mechanism is arranged on the outside of the limit fixing mechanism 7. Structure 8, a detection head 9 that moves up and down is provided in the middle of the moving mechanism 8, a connecting cable 91 is provided at the bottom of the detection head 9, and the connecting cable 91 passes through the wire management component 12 and is connected to the bottom of the lifting detection component 3, vacuum adsorption disks 15 are provided at the top ends of both sides of the limiting and fixing mechanism 7, and a connecting tube 151 is connected to the back end of the vacuum adsorption disk 15, and the top end of the other side of the connecting tube 151 is connected to the vacuum machine 10, the wire management component 12 is provided with 3 groups, and it includes a protective frame 121 and a wire-passing mechanism 122, the wire-passing mechanism 122 is provided in the reserved groove 14 at the top of the AGV trolley 1, and the outside of the wire-passing mechanism 122 is engaged with the protective frame 121.

[0032] The present application provides a blade surface UT detection device with a wire management component 12. Specifically, when in use, first, the entire detection device moves with the AGV trolley 1 above the AGV trolley 1 according to the set degree. When it moves to the vicinity of the blade, (external staff need to clean the fan blade in advance. After the cleaning is completed, according to the movement of the AGV trolley 1, the coupling agent needs to be applied to the cleaned blade surface) start the suspension mechanism 13, so that it drives the lifting detection component 3 to move up and down in the middle of the fixed frame 2. When it moves up and down to the appropriate position, it is necessary to The rotating rods 6 on both sides of the control fixing seat 5 are controlled to change their angles. After rotating to the appropriate position, the limiting fixing mechanism 7 at its top is controlled again under the action of the angle adjustment mechanism 11 to drive the detection head 9 on its top moving mechanism 8 to be in a state of contact with the blade. After the position is determined, the vacuum machine 10 is started so that it controls the adsorption work between the vacuum adsorption disk 15 and the blade. Finally, the detection head 9 is controlled to move up and down above the moving mechanism 8 to complete the up and down detection work of the fixed position. At the same time, the moving mechanism 8 can also move back and forth above the limiting fixing mechanism 7, thereby driving the detection head 9 to move back and forth to complete the detection work. In this application, the AGV 1 achieves automated material handling and task execution through the coordinated work of a navigation system, a drive system, a control system, a safety system, a communication system, and an energy system. The specific system coordination principle is the same as that of the AGV disclosed in application number 202110388144.9. The detection principle of the detection head 9 is that the pulse generator in the lifting detection component 3 generates a high-frequency electrical pulse signal, which excites the piezoelectric chip in the ultrasonic detection head 9, causing it to generate mechanical vibration and emit high-frequency ultrasonic waves. The emitted ultrasonic waves propagate in the material of the wind turbine blade. When encountering defects or interfaces between different media, reflection, refraction, or scattering occurs. The ultrasonic probe receives the ultrasonic signal reflected from the inside of the material and converts it into an electrical signal. By analyzing the time difference of the reflected wave, the waveform change, and other data, the specific location, size, and nature of the defect are calculated. Finally, the processed signal is presented to the operator in graphical or digital form through the display on the AGV 1. The data processing system generates a detailed inspection report, recording information such as the location, size, and nature of the defect, completing the inspection work.

[0033] As a further preferred embodiment of the present invention, when controlling the lifting detection component 3 to move up and down, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the fixed frame 2 is arranged in a rectangular frame type structure, and the four top corners of the rectangular frame are provided with limit rollers 21. The lifting detection component 3 includes a detection body 31, a lifting frame 32 and a sliding frame 33. The outer side of the detection body 31 is connected to the lifting frame 32, and the four top corners of the lifting frame 32 are connected to the sliding frame 33, and the sliding frame 33 slides on the four support rods outside the fixed frame 2.

[0034] The suspension mechanism 13 includes a rotating motor 131, a winding shaft 132 and a connecting cable 133. The top end of the rotating motor 131 is coaxially connected to the winding shaft 132. Two groups of connecting cables 133 are wound around the outside of the winding shaft 132. The top ends of the two groups of connecting cables 133 respectively pass around the limiting rollers 21 at the corresponding positions of the fixed frame 2 and are connected to the lifting detection component 3.

[0035] Specifically, first, it is necessary to simultaneously start the rotating motor 131 on the two sets of suspension mechanisms 13, so that it drives the winding shaft 132 at its top to rotate. When it rotates, it will reel in the connecting cable 133. When it reels in, the connecting cable 133 will pull the lifting frame 32 up and down under the limiting action of the limiting roller 21, and then the outer side of the lifting frame 32 will drive the sliding frame 33 to slide on the outer support rod of the fixed frame 2, and the middle will drive the entire detection body 31 to move up and down. At the same time, since the top of the lifting frame 32 is still connected to the connecting seat 4, when the lifting frame 32 is lifted, the connecting seat 4 and the fixed seat 5 at its top and the limiting fixing mechanism 7 at the top of the rotating rod 6 are also lifted and lowered, completing the height adjustment of the limiting fixing mechanism 7, and then the limiting fixing mechanism 7 can drive the moving mechanism 8 and the detection head 9 to reach the appropriate detection height.

[0036] Among them, when the rotating rod 6 rotates, according to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, the interior of the fixed seat 5 is set as a hollow structure, and a rotating shaft is set inside the hollow structure, and the two sides of the rotating shaft are respectively connected to two rotating rods 6, and a belt transmission mechanism is set on the outside of the rotating shaft to be connected to the servo motor. The belt transmission mechanism includes two pulleys and a transmission belt. The transmission belt is set outside the two pulleys, and the two pulleys are coaxially connected to the driving shaft of the servo motor and the rotating shaft inside the fixed seat 5 respectively. Specifically, first, the servo motor needs to be started so that it drives the pulley at its top to rotate. When the pulley rotates, the belt transmission work will cause the pulley coaxially connected to the outside of the rotating shaft to rotate, and the pulley drives the rotating shaft to rotate. Therefore, when the rotating shaft rotates, the purpose of driving the two rotating rods 6 to change the angle is achieved.

[0037] Furthermore, when the angle of the limiting fixing mechanism 7 is changed, according to Figure 7 and Figure 9 As shown, the angle adjustment mechanism 11 includes a mounting frame 111, a driving gear 112, a driving motor 113, an engaging gear 114, an intermediate shaft 115 and a connecting block 116. The mounting frame 111 is arranged at the top of the rotating rod 6, and a support seat is provided on the outside of the mounting frame 111. A driving motor 113 is provided above the support seat, and the top of the driving motor 113 is coaxially connected with the driving gear 112, the outer side of the driving gear 112 is connected to the engaging gear 114, the middle of the engaging gear 114 is provided with an intermediate shaft 115, and the middle of the intermediate shaft 115 is connected to the connecting block 116, and the top of the connecting block 116 is connected to the outer side of the limiting rod 71.

[0038] Specifically, it is necessary to start the driving motor 113 on the mounting frame 111 so that it drives the driving gear 112 at its top to rotate. When rotating, it will engage with the meshing gear 114, thereby causing the meshing gear 114 to rotate and drive the intermediate shaft 115 to rotate. Therefore, when the intermediate shaft 115 rotates, it drives the connecting block 116 to rotate, and the connecting block 116 drives the limiting fixing mechanism 7 to change its angle.

[0039] As a further preferred embodiment of the present invention, according to Figure 7 and Figure 8 As shown, the limiting and fixing mechanism 7 includes a limiting rod 71, a sliding box 72 and an active component 73. The outside of the limiting rod 71 is provided with a sliding box 72 connected by a slide rail groove, and the middle of the sliding box 72 is provided with an active component 73. The active component 73 includes an active motor 731 and a driving gear 732. The top of the active motor 731 is coaxially connected to the driving gear 732, and the outer side of the driving gear 732 is engaged with the tooth blocks at equal intervals on the outer side of the limiting rod 71. The top ends of both sides of the limiting rod 71 are connected to the vacuum adsorption disk 15. The top of the sliding box 72 is provided with an active motor 731, and the outer side of the sliding box 72 is connected to the moving mechanism 8.

[0040] The moving mechanism 8 includes a moving frame and a rotating screw 81 inside the moving frame. The top end of the rotating screw 81 is coaxially connected to the control motor, and the outside of the rotating screw 81 is threadedly connected to the sliding seat 92, and the top end of the sliding seat 92 is connected to the detection head 9.

[0041] Specifically, when the position of the limit fixing mechanism 7 is determined and the vacuum adsorption disk 15 is adsorbed and fixed to the blade, the position of the detection head 9 can be changed. First, the control motor is started to drive the rotating screw 81 to rotate, which will cause the rotating screw 81 to be threadedly connected to the sliding seat 92 on the back of the detection head 9. As a result, under the action of the sliding seat 92, the detection head 9 is driven to move up and down. Afterwards, the active motor 731 is started to drive the active gear 732 at its bottom to rotate, so that the active gear 732 and the tooth block on the limit rod 71 are engaged with each other. As a result, the entire active component 73 drives the sliding box 72 to move outside the limit rod 71. When the sliding box 72 moves, it drives the moving frame as a whole to move, thereby completing the purpose of driving the detection head 9 on the rotating screw 81 inside the moving frame to move together.

[0042] As a further preferred embodiment of the present invention, when the position limiting fixing mechanism 7 moves and drives the detection head 9 and the vacuum adsorption plate 15 to change their positions, the connecting cable 91 at the bottom of the detection head 9 and the connecting tube 151 at the bottom of the vacuum adsorption plate 15 will also be driven to move together, so it is necessary to use the wire management component 12 for sorting work. Figure 10 、 Figure 11 and Figure 12 As shown, the wire passing mechanism 122 includes a trigger component, a transmission component 16, an external wire-managing mechanism 18 and an intermediate wire-managing mechanism 19. The trigger component and the external wire-managing mechanism 18 are symmetrically arranged in two groups inside the reserved groove 14, and an intermediate wire-managing mechanism 19 is arranged in the middle of the two groups of external wire-managing mechanisms 18. The trigger component includes rotating rollers 17 arranged at equal intervals, and a transmission component 16 is arranged on the outside of the rotating roller 17. The transmission component 16 includes a connecting gear 161, an engaging toothed belt 162, a winding shaft 163 and a functional gear 164. The connecting gear 161 is coaxially connected to the outside of the rotating roller 17, and an engaging toothed belt 162 is arranged on the outside of the connecting gear 161. A functional gear 164 is arranged on the inner side of the top of the engaging toothed belt 162, and the top of the functional gear 164 is coaxially connected to the winding shaft 163, and a connecting pull wire 20 is wound around the outside of the winding shaft 163.

[0043] The external wire management mechanism 18 includes two groups of external fixing frames 181, a first fixed plate 185 is provided at the bottom of the external fixing frame 181, and a first return spring 182 is provided at the top of the first fixed plate 185 and is connected to the first sliding rectangular block 183, a first wire management roller 184 connected by a bearing is provided in the middle of the two first sliding rectangular blocks 183, the bottom of the first sliding rectangular block 183 is connected to one side of the connecting wire 20, and the other side of the connecting wire 20 passes through the first fixed plate 185 and is wound around the outside of the winding shaft 163.

[0044] The intermediate wire-managing mechanism 19 includes an intermediate fixed frame 191, a second fixed plate 192, a second return spring 193, a second sliding rectangular block 194 and a second wire-managing roller 195. The intermediate fixed frame 191 is provided with two groups, and a second fixed plate 192 is provided at the top inner side thereof. The bottom of the second fixed plate 192 is provided with a second return spring 193 connected to the second sliding rectangular block 194, and the intermediate bearings of the two second sliding rectangular blocks 194 are connected to the second wire-managing roller 195.

[0045] Specifically, at the beginning of the entire device, the protective frame 121 needs to be opened so that the entire wire-passing mechanism 122 is completely exposed, so that the middle of the connecting cable 91 and the connecting tube 151 pass through the outside of the first wire-winding roller 184 and the second wire-winding roller 195 at the corresponding positions respectively, and then the protective frame 121 is engaged. Since grooves are provided on the front and back sides of the protective frame 121, the connecting cable 91 and the connecting tube 151 can be limited to the top of the trigger mechanism inside the reserved groove 14. When the connecting cable 91 and the connecting tube 151 move, the friction force causes the rotating rollers 17 arranged at equal intervals on the trigger mechanism to rotate. When the rotating rollers 17 rotate, they cause the various connecting gears 161 coaxially connected thereto to rotate. When the connecting gears 161 rotate, The meshing toothed belt 162 rotates, thereby causing the meshing toothed belt 162 to drive the functional gear 164 to rotate. When the functional gear 164 rotates, it will drive the winding shaft 163 coaxially connected thereto to rotate, thereby the winding shaft 163 will take up and unwind the connecting wire 20. When taking up the wire, it will pull the first sliding rectangular block 183 to squeeze the first return spring 182 to descend, thereby driving the first wire-winding roller 184 to descend, thereby shortening the path of the connecting cable 91 and the connecting tube 151 moving between the two first wire-winding rollers 184, thereby also providing for external movement. On the contrary, if the path becomes longer, the excess length of the connecting cable 91 and the connecting tube 151 will be automatically recovered to ensure that the connecting cable 91 and the connecting tube 151 will not be entangled, dragged or damaged.

[0046] Furthermore, when the height of the two first cable-managing rollers 184 changes, the middle of the connecting cable 91 and the connecting tube 151 will apply force to the second cable-managing roller 195, thereby causing the second cable-managing roller 195 to squeeze the second sliding rectangular block 194, causing the second sliding rectangular block 194 to squeeze the second return spring 193, thereby achieving the purpose of further shortening the length of the connecting cable 91 and the connecting tube 151 inside the cable-managing assembly 12, thereby facilitating the position change work of the external detection head 9 and the vacuum adsorption disk 15.
