Description

Technical Field

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

[0002] Wind turbine blades are one of the core components of wind turbines, converting wind energy into mechanical energy to drive the generator and produce electricity. Wind turbine blades typically consist of a blade root, main beam, web, and outer shell. Strength testing of wind turbine blades is crucial for ensuring their long-term stable operation and resistance to extreme loads and fatigue damage. Currently, strength testing of wind turbine blades can simulate human vision using visual inspection equipment. High-resolution industrial cameras, lenses, and light sources are used to acquire images of the blade surface, which are then processed and analyzed by computer software. This process avoids contact with the blade surface and prevents secondary damage.

[0003] However, visual inspection equipment is susceptible to image quality issues caused by insufficient light or dirt on the blade surface, leading to inspection errors. Currently, most wind turbine blades are cleaned manually by staff, with the inspection and cleaning areas often separated. This requires transferring the cleaned blades to the inspection area, during which dust may re-adhere to the blade surface, affecting the inspection results. Therefore, there is a need to develop a strength inspection device that can clean the outer surface of wind turbine blades during inspection. Utility Model Content

[0004] To address the above technical problems, this utility model provides a strength testing device that can clean the outer surface of wind turbine blades during testing, thereby solving the problems of existing testing devices requiring manual cleaning of the blade surface, which is inefficient and may cause dust to re-adhere to the outer surface of the blade during inter-regional transfer.

[0005] To solve the above-mentioned technical problems, the present invention provides a wind turbine blade strength testing device, which includes a testing bracket, a visual inspection component for testing wind turbine blades, and a cleaning component for cleaning wind turbine blades.

[0006] The vision inspection component includes a vision inspection bracket, an industrial camera disposed inside the vision inspection bracket, supplementary lights disposed on the left and right sides of the industrial camera, and a first connecting ring welded to the left and right sides of the vision inspection bracket.

[0007] The cleaning assembly includes a slidable arc-shaped rod, a cleaning cloth disposed below the arc-shaped rod, a support column sleeved on the bottom of the arc-shaped rod, second connecting rings disposed on the left and right sides of the support column, and a flexible rope fixed between the second connecting ring and the first connecting ring.

[0008] Furthermore, the vision inspection component also includes a connecting rod welded to the top of the vision inspection bracket, and the connecting rod is provided with a driving component for driving the vision inspection component to move.

[0009] Furthermore, the drive assembly includes a transmission screw rotatably mounted on the inner side of the top of the connecting rod via a screw sleeve, a support frame mounted on the outside of the transmission screw via a bearing, and a servo motor fixed to the side of the support frame via bolts. The output end of the servo motor is fixedly connected to one end of the transmission screw.

[0010] Furthermore, the detection bracket includes a support base plate disposed below the visual inspection bracket, support side plates fixedly installed on the left and right sides of the support base plate, and fixed pillars fixed at the four corners of the support base plate. A fixed top plate is fixedly connected to the top of the fixed pillars, and a guide groove adapted to the size of the connecting rod is opened inside the fixed top plate.

[0011] Furthermore, the cross-section of the supporting side plate is a right-angled triangle structure, and the side of the supporting side plate away from the supporting base plate is lower than the side of the supporting side plate close to the supporting base plate.

[0012] Furthermore, the cleaning assembly also includes a limiting slider fixed to the bottom of the support column and a limiting groove formed at the connection between the limiting slider and the support base plate. A limiting plate is fixedly connected to the outer side of the end of the arc-shaped rod, and a connecting spring is fixedly connected between the limiting plate and the support column.

[0013] This utility model has the following advantages compared with the prior art:

[0014] This invention features a cleaning component that can be connected to a vision inspection bracket via a flexible rope. When the vision inspection bracket moves under the drive of the drive component, it can cause the arc-shaped rod to slide and move the cleaning cloth to clean the wind turbine blades. The vision inspection component can also move along the guide groove under the action of the drive component, and the industrial camera can capture images of the wind turbine blades to achieve visual inspection of the wind turbine blades.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-5 The wind turbine blade strength testing device shown includes a testing bracket 1, a visual inspection component 3 for testing wind turbine blades, and a cleaning component 4 for cleaning wind turbine blades.

[0023] The visual inspection component 3 includes a visual inspection bracket 302, an industrial camera 303 fixedly connected inside the visual inspection bracket 302, supplementary lights 304 fixedly connected to the lower end of the visual inspection bracket 302 and located on the left and right sides of the industrial camera 303, and first connecting rings 305 welded to the left and right outer sides of the visual inspection bracket 302. It should be noted that in this embodiment, the use of the industrial camera 303 and computer software for visual inspection of the surface of wind turbine blades is existing technology, and the raw materials, structure and connection relationship of the specific device and working process will not be described in detail here.

[0024] The cleaning component 4 includes a slidable arc-shaped rod 404, a cleaning cloth 5 disposed below the arc-shaped rod 404, a support column 403 sleeved on the bottom of the arc-shaped rod 404, a second connecting ring 405 fixedly connected to the left and right sides of the support column 403, and a flexible rope 406 fixed between the second connecting ring 405 and the first connecting ring 305. The flexible rope 406 has hooks at both ends and is connected to the second connecting ring 405 and the first connecting ring 305 through the hooks.

[0025] Specifically, the vision inspection component 3 also includes a connecting rod 301 welded to the top of the vision inspection bracket 302. The connecting rod 301 is located at the output end of the drive component 2, which is used to drive the movement of the vision inspection component 3. The connecting rod 301 is rotatably connected to the transmission screw 202 via a threaded sleeve. The transmission screw 202 is rotatably mounted on the inner side of the support frame 203 via a bearing. A servo motor 201 is fixedly connected to the outer side of the support frame 203 via bolts. The output end of the servo motor 201 is fixedly connected to one end of the transmission screw 202. The transmission screw 202 can drive the connecting rod 301 to slide inside the guide groove 204 via the threaded sleeve.

[0026] The flexible rope 406 is used to connect the support column 403 and the vision inspection bracket 302. Under the action of the drive component 2, it can drive the vision inspection component 3 to move laterally. When it is necessary to clean the wind turbine blades, the cleaning component 4 can be moved by the flexible rope 406 to achieve the cleaning of the wind turbine blades.

[0027] The inspection bracket 1 includes a support base plate 102 disposed below the visual inspection bracket 302. Support side plates 101 are fixedly connected to the left and right sides of the support base plate 102. Fixed support columns 103 are fixedly connected to the four corners of the upper surface of the support base plate 102. Fixed top plate 104 is fixedly connected to the upper end of the fixed support column 103. The fixed top plate 104 has a guide groove 204 that matches the size of the connecting rod 301. The guide groove 204 is used to guide the connecting rod 301.

[0028] The support side plate 101 has a certain slope to facilitate the movement of wind turbine blades to the support base plate 102. The cross-section of the support side plate 101 is a right-angled triangular structure, and the side of the support side plate 101 away from the support base plate 102 is lower than the side of the support side plate 101 close to the support base plate 102.

[0029] The cleaning component 4 also includes a limiting slider 401 fixed to the bottom of the support column 403 and a limiting groove 402 opened at the connection between the limiting slider 401 and the support base plate 102. The limiting groove 402 is used to guide the limiting slider 401.

[0030] A limiting plate 407 is fixedly connected to the end of the arc-shaped rod 404, and a connecting spring 408 is fixedly connected between the limiting plate 407 and the support column 403.

[0031] The arc-shaped rod 404 can be connected to the support column 403 through the connecting spring 408. Pulling the arc-shaped rod 404 can stretch the connecting spring 408. The arc-shaped rod 404 can surround the wind turbine blade. Under the action of the connecting spring 408, the arc-shaped rod 404 can be driven to stick tightly to the wind turbine blade.

[0032] The working principle of this embodiment is as follows:

[0033] In use, a dust collection component is also installed on the fixed top plate 104. The dust collection component uses existing dust collection equipment to remove dust from the surface of the wind turbine blades. The power output end of the servo motor 201 drives the transmission screw 202 to rotate. The transmission screw 202 can drive the connecting rod 301 to slide inside the guide groove 204 through the threaded sleeve. The guide groove 204 guides the connecting rod 301. The connecting rod 301 can drive the vision inspection bracket 302 to move laterally. The first connecting ring 305 on the side of the vision inspection bracket 302 can be connected to the second connecting ring 405 of the support column 403 through the flexible rope 406, thereby driving the cleaning component 4 to slide. When the arc rod 404 moves, it can drive the cleaning cloth 5 to slide. The cleaning cloth 5 cleans the wind turbine blades. After cleaning, the industrial camera 303 is activated to realize image acquisition. The cleaning component 4 is connected to the vision inspection bracket 302 via a flexible rope 406. When the vision inspection bracket 302 moves under the drive of the drive component 2, it can drive the arc-shaped rod 404 to slide, and move the cleaning cloth 5 to clean the wind turbine blades. The cleaning cloth 5 can be a lint-free cloth used to clean the wind turbine blades. During cleaning, the arc-shaped rod 404 is pulled, stretching the connecting spring 408. The wind turbine blades are located between the arc-shaped rods 404. At this time, under the action of the connecting spring 408, the arc-shaped rods 404 can be driven to press against the wind turbine blades. The cleaning cloth 5 is clamped between the wind turbine blades and the arc-shaped rods 404, with one end fixed to the arc-shaped rods 404. When the arc-shaped rods 404 move, they can drive the cleaning cloth 5 to clean the surface of the wind turbine blades. The vision inspection component 3 can move along the guide groove 204 under the action of the drive component 2. The industrial camera 303 acquires images of the wind turbine blades, realizing the visual inspection of the wind turbine blades.
