Due to the particularity of the work of wind turbines, wind turbine blades are in variable loads and harsh environments for a long time. As the size of the blades continues to increase, wind turbine blade fracture incidents occur from time to time. As an important component of wind turbine blades, the quality of pultruded plates directly affects the performance and safety of wind turbine blades. Basalt fiber pultruded plates have good thermal stability and fatigue resistance, and can operate stably for a long time in harsh natural environments.

[0042] Combine the following Figure 1 and Figure 2 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] The embodiment of the present application discloses a pultruded plate ultrasonic detection device, which includes a bearing mechanism and an ultrasonic scanning mechanism arranged on the bearing mechanism;

[0044] The bearing mechanism includes a bearing frame 10 and a placing plate 20 disposed on the bearing frame 10 , and the placing plate 20 is used for placing the basalt fiber pultruded plate.

[0045] The ultrasonic scanning mechanism includes a support frame 30, a probe frame 40 and a first elastic member 36. The support frame 30 can be laterally slidably arranged on the carrier frame 10 and is located above the placement plate 20. It mainly provides the probe frame 40 with a lateral translation relative to the pultruded plate to facilitate the probe 43 to scan across the pultruded plate.

[0046] The probe frame 40 is slidably disposed on the support frame 30 via at least two vertically extending slide rails, each of which is arranged in parallel in a transverse direction, and the bottom of the probe frame 40 is used for mounting the probe 43;

[0047] The first elastic member 36 is disposed between the probe frame 40 and the support frame 30 , and is used to provide a first downward elastic force for the probe frame 40 , so that the probe 43 can press the basalt fiber pultruded board.

[0048] In this way, by setting the first elastic member 36 between the probe frame 40 and the support frame 30, the first elastic force provided by the first elastic member 36 makes the probe frame 40 have a downward movement tendency, and at least two slide rails arranged in parallel laterally can guide the probe 43 to perform precise vertical linear movement, so that the probe 43 installed at the bottom of the probe frame 40 can be flexibly and tightly attached to the surface of the basalt fiber pultruded board and evenly stressed, so as to facilitate more accurate defect detection using ultrasonic information. Moreover, due to the first elastic force provided by the first elastic member 36 and the ability of the support frame 30 to move laterally relative to the carrier frame 10, when the support frame 30 drives the probe frame 40 to move laterally, the probe 43 can also be closely attached to the surface of the basalt fiber pultruded board, and there is no need to manually press the probe 43 on the pultruded board, so that continuous scanning detection can be achieved, more detailed information can be captured, detection is more accurate, and efficiency is higher, and the needs of large-scale production and rapid detection can be met.

[0049] The carrier frame 10 can specifically adopt a three-dimensional frame structure composed of multiple horizontal steel beams and multiple vertical steel beams 11. The horizontal steel beams can be connected and fixed with the vertical steel beams 11 through a commonly used locking structure 14, which is convenient for the assembly of the entire carrier frame 10. The overall structure of the hollow three-dimensional frame of the carrier frame 10 is lightweight and easy to carry.

[0050] The support frame 30 can be suspended on the upper cross steel beam 12 of the carrier frame 10 in a transversely slidable manner through the slider 15, so that the support frame 30 can move transversely relative to the placement plate 20 when a transverse driving force is applied to it.

[0051] A plurality of rollers 13 are arranged at the bottom of the carrier 10. For example, a roller 13 is arranged at the bottom end of each vertical steel beam 11 of the carrier 10. This facilitates manual movement of the entire pultruded plate ultrasonic detection device, so that it can be carried to various environments.

[0052] The support frame 30 is roughly in the form of a quadrilateral frame structure, and includes an upper member 31 and a lower member 32 arranged vertically opposite to each other, a first side member 33 connected between one end of the upper member 31 and one end of the lower member 32, and a second side member 34 connected between the other end of the upper member 31 and the other end of the lower member 32, and all the slide rails are located between the first side member 33 and the second side member 34.

[0053] The probe frame 40 is roughly T-shaped, and includes a movable base 41 and a probe mounting frame 42. The movable base 41 extends horizontally and is slidably connected to all the slide rails. The probe mounting frame 42 extends vertically, passes through the lower member 32 and extends out. The probe mounting frame 42 is slidably matched with the lower member 32. The probe mounting frame 42 is connected to the movable base 41, and the bottom of the probe mounting frame 42 is used for installing the probe 43.

[0054] The slide rail can specifically be a rod-shaped structure, for example, the slide rail includes but is not limited to a sliding rod 35, the two ends of the sliding rod 35 are respectively connected to the upper component 31 and the lower component 32, and the probe frame 40 is provided with at least two sliding holes, each sliding rod 35 passes through a sliding hole, so as to ensure that the probe frame 40 itself will not deviate during the vertical linear movement.

[0055] The ultrasonic scanning mechanism also includes a height adjustment member, which is arranged on the support frame 30, and the bottom end of the height adjustment member is opposite to the top of the movable base 41 of the probe frame 40. The vertical position of the height adjustment member relative to the support frame 30 can be adjusted. In this way, the maximum height of the probe frame 40 can be limited by changing the vertical position of the height adjustment member, so that during the lateral movement of the probe 43, the rigid contact between the bottom end of the height adjustment member and the top of the movable base 41 can prevent the probe frame 40 from moving up and down too much.

[0056] Specifically, the height adjustment member includes a connected adjustment knob 50 and an adjustment rod 51. The adjustment rod 51 extends vertically and is threadedly matched with the upper component 31 of the support frame 30. The bottom end of the adjustment rod 51 is opposite to the top of the probe frame 40. In this way, it is only necessary to turn the adjustment knob 50 to drive the adjustment rod 51 and the upper component 31 to perform spiral motion, thereby changing the height position of the bottom end of the adjustment rod 51. It is easy to implement and can be operated through a purely mechanical structure, reducing unstable factors such as failures.

[0057] The first elastic member 36 is a tubular element, such as a spring. The first elastic member 36 is sleeved outside the adjustment rod 51 , and two ends of the first elastic member 36 are respectively connected to the upper member 31 and the movable base 41 of the probe frame 40 .

[0058] In addition, the ultrasonic scanning mechanism also includes a second elastic member 37, which is arranged between the support frame 30 and the probe frame 40, and is used to provide a second upward elastic force for the probe frame 40, wherein the first elastic force is greater than the second elastic force. In this way, through the arrangement of the second elastic member 37, the probe frame 40 can be at a centered initial height relative to the support frame 30 without the need for ultrasonic testing, thereby avoiding the probe 43 from being too low and affecting the placement of the pultruded plate on the placement plate 20, and reducing the risk of collision and damage to the probe 43 during the placement of the pultruded plate.

[0059] The second elastic member 37 may also be a tubular element, such as a spring. Each sliding rod 35 is covered with a second elastic member 37 , so that the telescopic length of the second elastic member 37 outside each sliding rod 35 is consistent, which can ensure the flat angle of the probe 43 .

[0060] The supporting mechanism also includes a connected wheel 60 and a linkage rod 61. The linkage rod 61 extends laterally and is threadedly engaged with the second side member 34 of the supporting frame 10. The end of the linkage rod 61 away from the wheel 60 is rotatably connected to the support frame 30. In this way, it is only necessary to rotate the wheel 60 to drive the linkage rod 61 and the second side member 34 to produce a spiral motion, thereby realizing the lateral movement of the support frame 30 relative to the placement plate 20. Moreover, the operation can be realized through a purely mechanical structure, reducing unstable factors such as failures.

[0061] The rotatable connection between the linkage rod 61 and the support frame 30 can be realized in the following manner. For example, a snap ring 70 is installed on the second side member 34 of the support frame 30. The snap ring 70 has a radially inwardly protruding retaining ring 71. The retaining ring 71 and the support frame 10 form a movable cavity 72. The end of the linkage rod 61 away from the wheel disc 60 has a radially outwardly protruding limiting ring 62. The limiting ring 62 is located in the movable cavity 72, and the inner diameter of the retaining ring 71 is smaller than the outer diameter of the limiting ring 62. In this way, when the linkage rod 61 rotates, the limiting ring 62 can rotate in the movable cavity 72. At the same time, since the inner diameter of the retaining ring 71 is smaller than the outer diameter of the limiting ring 62, the linkage rod 61 will not be separated from the support frame 30. When assembling, the snap ring 70 is firstly put on the linkage rod 61, and then the snap ring 70 is connected and fixed to the support frame 30 by fasteners such as screws.

[0062] In summary, compared with the prior art, this embodiment has the following effects:

[0063] 1. Wide application: The device is portable and compact and can be carried to various environments for use.

[0064] 2. High precision: There is no need to hold the probe 43 for operation, and the operation can be achieved through a mechanical structure, reducing artificial instability factors.

[0065] 3. Low cost: The device adopts semi-automatic operation, which does not require the development of particularly complex interactive software and also reduces the failure rate.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
