Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade testing technology, specifically a wind power new energy blade testing device. Background Technology

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. It includes energy sources that are just beginning to be developed and utilized or are under active research and awaiting widespread adoption, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. Wind energy, as a clean and renewable energy source, has enormous development potential in the future and is an important component of new energy. Wind turbine blades are one of the core components of wind turbine units, and their performance directly affects the efficiency of wind power generation.

[0003] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy. They are also the main basis for evaluating the design and technical level of wind turbines. In order to ensure the normal use of new energy wind turbine blades, quality inspection must be carried out on the blades after manufacturing.

[0004] A search revealed a patent document with publication number CN 221199503 U, which discloses a new energy wind turbine blade testing device. The device includes a wind turbine blade body, a fixing unit, and a testing unit. The fixing unit is used to fix the wind turbine blade body, and the testing unit is used by the fixing unit to test the fixed wind turbine blade body. The testing unit includes a motor, a ball screw, a threaded sleeve, a PLC control box, an ultrasonic testing probe, and a high-definition camera. The lower output shaft of the motor is fixedly connected to the ball screw, and a threaded sleeve is threaded onto the outer wall of the ball screw. One end of the threaded sleeve is equipped with the PLC control box, and one end of the PLC control box is electrically connected to the ultrasonic testing probe and the high-definition camera. Compared to the existing method of placing the wind turbine blade body on a conveyor using a large hoisting unit before testing, this invention is more convenient to use, simpler to operate, reduces safety hazards, and increases the testing efficiency of the wind turbine blade body.

[0005] In the aforementioned prior art, wind turbine blades are inspected using an ultrasonic testing probe and a high-definition camera. During inspection, the PLC control box can be moved by a ball screw and a screw sleeve, which facilitates the alignment of the ultrasonic testing probe and the high-definition camera with the wind turbine blade for inspection. However, this method can only inspect one side of the wind turbine blade and cannot simultaneously inspect both sides, affecting inspection efficiency. Therefore, a new wind power blade inspection device is proposed to optimize the aforementioned prior art. Utility Model Content

[0006] The purpose of this invention is to provide a wind power blade testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wind turbine blade testing device includes a frame positioned outside the wind turbine blade, which is supported by a bracket. Inside the frame, crossbeams are positioned above and below the wind turbine blade. A sliding groove is fixedly connected to the front surface of each crossbeam, and a matching slider is slidably connected within the groove. A lead screw is threaded through the slider, and the slider has threaded holes for the lead screw to pass through and be threaded. The lead screw is rotatably mounted within the groove. A drive motor is fixedly mounted at one end of the groove corresponding to one end of the lead screw, and the output end of the drive motor is fixedly connected to the end of the lead screw. An extension block is fixedly connected to the slider, and a rectangular vertical rod is slidably connected through the extension block. The extension block has an opening... A rectangular hole is provided for the rectangular vertical rod to pass through and slide. A ball wheel is installed on the end of the rectangular vertical rod that is close to the wind turbine blade. A PLC control box is fixedly connected to the side wall of the rectangular vertical rod where the ball wheel is installed. An ultrasonic detection probe and a high-definition camera are fixedly installed on the side of the PLC control box that is close to the wind turbine blade. A spring is sleeved on the outer side of the lower rectangular vertical rod. The spring is set between the corresponding crossbeam and the PLC control box. The drive motor, ultrasonic detection probe and high-definition camera are all electrically connected to the PLC control box. Only the five-risk module inside the PLC control box is connected to the external terminal equipment. The PLC control box is connected to an external power supply, which can be connected by a conductive slide rail.

[0009] As a further embodiment of this utility model: one end of the crossbeam is fixedly connected to a first kit, and the first kit is slidably sleeved on the side column of the frame.

[0010] As a further embodiment of this utility model: a threaded rod and a guide rod are fixedly connected to the inner side of the frame. The guide rod slides through the crossbeam. A circular hole is provided on the crossbeam for the guide rod to pass through and slide. The threaded rod moves through the crossbeam and is threadedly connected to nuts on both sides of the crossbeam. A circular hole is provided on the crossbeam for the threaded rod to move through.

[0011] As a further improvement of this utility model, each of the rectangular vertical bars having a stop piece fixedly connected to the side that is far apart from the other is a rectangular vertical bar.

[0012] As a further embodiment of this utility model: the bottom surface of the frame is symmetrically and fixedly connected to a slide block, the slide block is slidably connected to a slide rail, and the slide rail is fixedly connected to the base plate of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a set of ultrasonic detection probes and a high-definition camera above and below the wind turbine blade, so that flaw detection and photographic recording can be performed on both the upper and lower planes at the same time. Compared with the prior art, it is not necessary to go to the other side for inspection again, which increases the detection efficiency.

[0015] 2. The ultrasonic testing probe and high-definition camera of this utility model are fixedly mounted on a rectangular vertical rod via a PLC control box. The upper rectangular vertical rod always hangs downward under the action of gravity, and is pressed against the surface of the wind turbine blade by ball wheels, so that the distance between the ultrasonic testing probe and high-definition camera and the wind turbine blade is maintained. At the same time, the lower rectangular vertical rod is elastically supported by a spring, and is pressed against the surface of the wind turbine blade by ball wheels, so that the distance between the ultrasonic testing probe and high-definition camera and the wind turbine blade is maintained. This makes it convenient for the ultrasonic testing probe and high-definition camera to maintain a fixed distance from the wind turbine blade during mobile testing, without the need for manual adjustment of the distance.

[0016] 3. The crossbeam of this utility model is connected to the frame, guide rod and threaded rod at the same time. The first kit slides and guides the frame, the guide rod slides and guides the crossbeam, and the threaded rod is clamped and limited by the nut. Thus, the initial height of the crossbeam can be adjusted to facilitate the testing of wind turbine blades of different sizes.

[0017] 4. This utility model uses a drive motor to drive a lead screw to rotate, which in turn drives a slider to slide within a groove, thereby changing the lateral position of the ultrasonic testing probe and the high-definition camera. This facilitates the detection of different positions on the cross-section of the wind turbine blade. At the same time, the slide can slide on the slide rail, thereby changing the longitudinal position of the ultrasonic testing probe and the high-definition camera. This facilitates the detection of different positions along the length of the wind turbine blade, thus enabling comprehensive testing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 In this embodiment of the utility model, a wind power blade testing device includes a frame 1, which is set on the outside of the wind turbine blade. The wind turbine blade is supported by a bracket. A crossbeam 2 is provided inside the frame 1, corresponding to the top and bottom of the wind turbine blade. A sliding groove 3 is fixedly connected to the front surface of the crossbeam 2. A slider 4 adapted to the sliding groove 3 is slidably connected within the sliding groove 3. A lead screw 5 is threaded through the slider 4. The slider 4 has a threaded hole for the lead screw 5 to pass through and be threaded. The lead screw 5 is rotatably installed in the sliding groove 3. A drive motor 6 is fixedly installed at one end of the sliding groove 3 corresponding to one end of the lead screw 5. The output end of the drive motor 6 is fixedly connected to the end of the lead screw 5. An extension block 7 is fixedly connected to the slider 4. A rectangular vertical rod 8 is slidably connected through the extension block 7. A rectangular hole is provided on the extension block 7 for the rectangular vertical rod 8 to pass through and slide. A ball wheel 9 is installed at the end of the rectangular vertical rod 8 closest to the wind turbine blade. A PLC control box 10 is fixedly connected to the side wall of the rod 8 where the ball wheel 9 is mounted. An ultrasonic detection probe 11 and a high-definition camera 12 are fixedly installed on the side of the PLC control box 10 near the wind turbine blade. A spring 13 is sleeved on the outside of the rectangular vertical rod 8 below. The spring 13 is set between the corresponding crossbeam 2 and the PLC control box 10. The drive motor 6, the ultrasonic detection probe 11, and the high-definition camera 12 are all electrically connected to the PLC control box 10. Only the five-insurance module inside the PLC control box 10 is connected to the external terminal equipment. The PLC control box 10 is connected to an external power supply, which can be connected by a conductive slide rail. The ultrasonic detection probe 11 and the high-definition camera 12 are used to detect whether there are cracks on the outer wall of the wind turbine blade body. When cracks are detected on the surface of the wind turbine blade body, the high-definition camera 12 takes a picture of the surface of the wind turbine blade body and transmits it to the display end of the detection terminal.

[0024] An ultrasonic testing probe 11 and a high-definition camera 12 are installed above and below the wind turbine blade, so that flaw detection and photographic recording can be performed on both the upper and lower planes at the same time. Compared with the existing technology, it is not necessary to go to the other side for inspection again, which increases the detection efficiency.

[0025] The ultrasonic testing probe 11 and the high-definition camera 12 are fixedly mounted on the rectangular vertical rod 8 via the PLC control box 10. The upper rectangular vertical rod 8 always hangs down under the action of gravity, and is pressed against the surface of the wind turbine blade by the ball wheel 9, so that the distance between the ultrasonic testing probe 11 and the high-definition camera 12 and the wind turbine blade is maintained. At the same time, the lower rectangular vertical rod 8 is elastically supported by the spring 13, and is pressed against the surface of the wind turbine blade by the ball wheel 9, so that the distance between the ultrasonic testing probe 11 and the high-definition camera 12 and the wind turbine blade is maintained. This makes it convenient for the ultrasonic testing probe 11 and the high-definition camera 12 to always maintain a fixed distance from the wind turbine blade when moving for testing, without the need for manual adjustment of the distance.

[0026] By setting the ball wheel 9, the ball wheel 9 can travel on the surface of the wind turbine blade no matter how the rectangular vertical rod 8 moves relative to the wind turbine blade.

[0027] One end of the crossbeam 2 is fixedly connected to the first kit 20, which is slidably fitted onto the side column of the frame 1.

[0028] A threaded rod 14 and a guide rod 15 are fixedly connected to the inner side of the frame 1. The guide rod 15 slides through the crossbeam 2. A round hole is opened on the crossbeam 2 for the guide rod 15 to pass through and slide. The threaded rod 14 moves through the crossbeam 2 and is threaded with nuts 16 on both sides of the crossbeam 2. A round hole is opened on the crossbeam 2 for the threaded rod 14 to move through.

[0029] The crossbeam 2 is connected to the frame 1, the guide rod 15, and the threaded rod 14. It is guided by the first kit 20 sliding with the frame 1, the guide rod 15 sliding with the crossbeam 2, and the threaded rod 14 clamped and limited by the nut 16. Thus, the initial height of the crossbeam 2 can be adjusted to facilitate the testing of wind turbine blades of different sizes.

[0030] Each of the rectangular vertical bars 8 has a stop piece 17 fixedly connected to one of its opposite sides.

[0031] The stop piece 17 prevents the rectangular vertical bar 8 from slipping off the extension block 7.

[0032] A slide block 18 is symmetrically and fixedly connected to the bottom surface of frame 1. The slide block 18 is slidably connected to the slide rail 19, and the slide rail 19 is fixedly connected to the base plate of the support frame.

[0033] The drive motor 6 drives the lead screw 5 to rotate, which in turn drives the slider 4 to slide within the slide groove 3. This changes the lateral position of the ultrasonic testing probe 11 and the high-definition camera 12, facilitating the detection of different positions on the wind turbine blade cross-section. Simultaneously, the slide block 18 can slide on the slide rail 19, thereby changing the longitudinal position of the ultrasonic testing probe 11 and the high-definition camera 12. This facilitates the detection of different positions along the length of the wind turbine blade, enabling comprehensive testing.

[0034] The working principle of this utility model is as follows:

[0035] In use, the wind turbine blade is suspended on the bracket and located inside the frame 1. The height of the constant-connection pipe is adjusted by the guide rod 15 and the first component 20, ensuring that the end of the rectangular vertical rod 8 is as close as possible to the surface of the wind turbine blade, and that the ball wheel 9 is pressed against the blade. The crossbeam 2 is then clamped by the nut 16, fixing its position. Under gravity, the upper rectangular vertical rod 8 continues to fall, pressing against the surface of the wind turbine blade with the ball wheel 9, maintaining the distance between the ultrasonic detection probe 11 and the high-definition camera 12 and the wind turbine blade. Simultaneously, the lower rectangular vertical rod 8 is elastically supported by the spring 13, also pressing against the surface of the wind turbine blade with the ball wheel 9, maintaining the distance between the ultrasonic detection probe 11 and the high-definition camera 12 and the wind turbine blade. This facilitates easy movement of the ultrasonic detection probe during testing. The ultrasonic testing probe 11 and the high-definition camera 12 are always kept at a fixed distance from the wind turbine blade. Furthermore, the drive motor 6 drives the lead screw 5 to rotate, which in turn drives the slider 4 to slide in the slide groove 3, thereby changing the lateral position of the ultrasonic testing probe 11 and the high-definition camera 12. This facilitates the detection of different positions on the cross-section of the wind turbine blade. At the same time, the slide base 18 can slide on the slide rail 19, thereby changing the longitudinal position of the ultrasonic testing probe 11 and the high-definition camera 12. During the movement of the ultrasonic testing probe 11 and the high-definition camera 12, the outer wall of the wind turbine blade body is detected for cracks. When cracks are detected on the surface of the wind turbine blade body, the high-definition camera 12 takes a picture of the surface of the wind turbine blade body and transmits it to the display end of the detection terminal. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
