Description

Technical Field

[0001] The utility model belongs to the technical field of new energy, and particularly relates to a device for detecting the strength of a wind power generation blade. Background Art

[0002] With the popularization and sustainable development of wind power generation in China, the safe operation of wind turbine blades has become the focus of attention. As a key component of a wind turbine, the operating state of the blade directly affects the performance and lifespan of the entire wind power generation system. Therefore, it is of great significance to effectively detect wind turbine blades.

[0003] In the prior art, after retrieval, Chinese Patent No. CN208505798U discloses a device for detecting the strength of a wind turbine blade; it includes a base, a rotating sleeve is fixedly installed in the middle of the bottom surface of the inner cavity of the base, a driven bevel gear is fixedly sleeved outside the rotating sleeve, a rotating shaft is fixedly installed on the left side surface of the base, and the right end of the rotating shaft extends into the base and is fixedly sleeved with a driving bevel gear meshing with the driven bevel gear. This device for detecting the strength of a wind turbine blade enables the lower fastening plate to move up and down, and in cooperation with the positioning slide rod, the upper fastening plate, the telescopic rod, the buffer spring, the spring and the rubber pad, the lower fastening plate and the upper fastening plate are tightly clamped on the edge of the blade, providing a stable stress point for the subsequent detection of the blade strength, increasing the stability of this device for detecting the strength of a wind turbine blade, and improving the practicability of this device for detecting the strength of a wind turbine blade.

[0004] When detecting the strength of the blade, it is necessary to fix the position of the blade. However, the surface of the blade has a large curvature, so when fixing the position of the blade, it is easy to be unstable. The above scheme drives the driven gear to rotate through the rotating shaft and the driving gear, and the driven gear cooperates with the rotating sleeve, the clamping rod and the clamping groove to drive the rotating screw rod to drive the lower fastening plate to move. The lower fastening plate and the upper fastening plate are convenient for clamping and fixing the blade. However, due to the curvature of the blade, it is easy for the lower fastening plate and the upper fastening plate not to fully fit the surface of the blade during clamping, which may easily cause the blade to shake, thereby reducing the stability of blade fixation.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0031] Please refer to Figures 1-4 As shown, the present utility model is a wind power generation blade strength detection device, including a base plate 1. A fixed frame plate 2 is fixedly installed at the top of the base plate 1. A support assembly 3 is fixedly installed at the top of the fixed frame plate 2. A strength detection assembly 4 is arranged at the bottom of the support assembly 3. A driving assembly 5 is rotatably arranged inside the support assembly 3;

[0032] One side of the fixed plate 2 is provided with a rotating groove 6. An adjusting component 7 is rotatably arranged inside the rotating groove 6. A clamping component 8 is threadedly connected to the outer surface of the adjusting component 7. The clamping component 8 includes a connecting seat 801 and an arc-shaped clamping plate 802. The inside of the connecting seat 801 is threadedly connected to the outer surface of the adjusting component 7. One side of the connecting seat 801 is fixedly connected with a first mounting plate 803. An arc-shaped fixing plate 804 is fixedly installed on one side of the first mounting plate 803. One side of the arc-shaped fixing plate 804 is fixedly connected with an arc-shaped sliding block 805;

[0033] An arc-shaped sliding groove 806 is provided on one side of the arc-shaped clamping plate 802. The outer surface of the arc-shaped sliding block 805 is slidably arranged inside the arc-shaped sliding groove 806. Installation blocks 807 are fixedly connected to both ends of the arc-shaped clamping plate 802. An abutting block 808 is fixedly installed on one side of the installation block 807.

[0034] During use, by placing the wind power generation blade sample to be detected on the top of the abutting block 808, and then driving the adjusting component 7 to drive the connecting seat 801 to move. Since there are two groups of connecting seats 801 and they are symmetrically arranged, the adjusting component 7 can drive the two groups of connecting seats 801 to move relatively. The connecting seat 801 drives the first mounting plate 803 fixedly connected to its one side to move, so that the first mounting plate 803 drives the arc-shaped fixing plate 804 fixedly installed on its one side to move. Since an arc-shaped sliding block 805 is fixedly connected to one side of the arc-shaped fixing plate 804 and the outer surface of the arc-shaped sliding block 805 is slidably arranged on the inner wall of the arc-shaped sliding groove 806 provided on one side of the arc-shaped clamping plate 802, the arc-shaped fixing plate 804 can cooperate with the arc-shaped sliding block 805 and the arc-shaped sliding groove 806 to drive the arc-shaped clamping plate 802 to move. The arc-shaped clamping plate 802 drives the installation blocks 807 fixedly connected to its two ends to move. The installation blocks 807 drive the abutting blocks 808 fixedly installed on their one sides to contact the surface of the wind power generation blade to be detected, thereby fixing the position of the wind power generation blade. When the fixed position is the arc surface of the wind power generation blade, one group of abutting blocks 808 first contacts the surface of the wind power generation blade. Under the continuous movement of the arc-shaped clamping plate 802, the arc-shaped clamping plate 802 cooperates with the arc-shaped sliding groove 806 to slide on the outer surface of the arc-shaped sliding block 805. Then the arc-shaped clamping plate 802 can drive the other group of abutting blocks 808 to contact the surface of the wind power generation blade, thus completing the fixation of the wind power generation blade. Then, by starting the strength detection component 4, the surface strength of the wind power generation blade is detected. By rotating the driving component 5, the strength detection component 4 can be driven to move, so that multiple positions on the surface of the wind power generation blade can be detected, which is relatively convenient.

[0035] In this utility model, the wind power generation blade sample to be detected is placed at the top of the abutting block 808. By driving the adjustment assembly 7, the two connecting seats 801 move relatively. The connecting seats 801 drive the first mounting plate 803 and the arc-shaped fixing plate 804 to move. Since the arc-shaped fixing plate 804 cooperates with the arc-shaped slider 805 and the arc-shaped chute 806 to drive the arc-shaped clamping plate 802 to move, the arc-shaped clamping plate 802 cooperates with the mounting block 807 to drive the abutting block 808 to contact the surface of the wind power generation blade to be detected, completing the fixation. When the fixation position is the arc surface of the wind power generation blade, one set of abutting blocks 808 first contacts the surface of the wind power generation blade. Under the continuous movement of the arc-shaped clamping plate 802, the arc-shaped clamping plate 802 cooperates with the arc-shaped chute 806 to slide on the outer surface of the arc-shaped slider 805. Further, the arc-shaped clamping plate 802 can drive the other set of abutting blocks 808 to contact the surface of the wind power generation blade, thereby completing the fixation of the wind power generation blade. Further, the two sets of abutting blocks 808 can be completely attached to its surface, avoiding shaking and improving the stability during blade fixation.

[0036] In one embodiment, for the above-mentioned support assembly 3, the support assembly 3 includes a support frame 301. The bottom end of the support frame 301 is fixedly installed with the top end of the fixed frame plate 2. A sliding groove 302 is formed inside the support frame 301. A sliding block 303 is slidably arranged inside the sliding groove 302. One side of the sliding block 303 is fixedly connected to a moving plate 304.

[0037] The arrangement of the sliding groove 302 and the sliding block 303 can support and limit the moving plate 304 when it moves. And when the strength detection assembly 4 is working, it can apply pressure to the moving plate 304. The cooperation between the sliding groove 302 and the sliding block 303 can share the pressure, thereby avoiding the moving plate 304 from bending and further improving the stability of the moving plate 304.

[0038] In one embodiment, for the above-mentioned strength detection assembly 4, the strength detection assembly 4 includes a cylinder 401. The top end of the cylinder 401 is fixedly installed with the bottom end of the moving plate 304. The telescopic end of the cylinder 401 is fixedly connected to a mounting seat 402. The bottom end of the mounting seat 402 is fixedly installed with a second mounting plate 403. The bottom end of the second mounting plate 403 is fixedly installed with a hardness tester 404. A pressure head 405 is arranged at the bottom end of the hardness tester 404.

[0039] The telescopic end of the starting cylinder 401 drives the mounting seat 402 fixedly connected thereto to move downward. The mounting seat 402 drives the second mounting plate 403 fixedly installed at its bottom end to move. The second mounting plate 403 drives the hardness tester 404 fixedly installed at its bottom end to move. The hardness tester 404 drives the indenter 405 provided at its bottom end to contact the surface of the wind power blade. Then, the pressure data displayed by the hardness tester 404 is recorded to complete the strength detection of the blade, which is relatively convenient.

[0040] In one embodiment, for the above-mentioned driving assembly 5, the driving assembly 5 includes a rotating shaft 501 and a lead screw 502. The outer surface of the rotating shaft 501 is rotatably arranged inside the support frame 301. One end of the rotating shaft 501 is fixedly provided with a first crank 503. The other end of the rotating shaft 501 is fixedly provided with a first bevel gear 504.

[0041] The outer surface of the lead screw 502 is rotatably arranged inside the support frame 301. The outer surface of the lead screw 502 is threadedly connected to the inside of the moving plate 304. One end of the lead screw 502 is fixedly provided with a second bevel gear 505. The surface of the second bevel gear 505 meshes with the surface of the first bevel gear 504.

[0042] By rotating the first crank 503, the rotating shaft 501 fixedly connected inside it is rotated, so that it rotates inside the support frame 301. Then, the rotating shaft 501 drives the first bevel gear 504 fixedly provided at one end thereof to rotate, so that the first bevel gear 504 can drive the second bevel gear 505 meshing with its surface to rotate. Thus, the second bevel gear 505 drives the lead screw 502 fixedly installed inside it to rotate. Since the threaded surface of the lead screw 502 is threadedly arranged with the inside of the moving plate 304, when the lead screw 502 rotates, it can drive the moving plate 304 to move, thereby adjusting the position of the moving plate 304, which is relatively convenient.

[0043] In one embodiment, for the above-mentioned adjusting assembly 7, the adjusting assembly 7 includes a bidirectional screw 701. The outer surface of the bidirectional screw 701 is rotatably arranged inside the rotating groove 6. The top end of the bidirectional screw 701 is fixedly connected with a second crank 702. The outer surface of the bidirectional screw 701 is threadedly connected to the inside of the connecting seat 801.

[0044] By rotating the second crank 702, the bidirectional screw 701 fixedly connected inside it is driven to rotate. Due to the thread surfaces of the bidirectional screw 701 and the internal threads of the two sets of connecting seats 801, when the bidirectional screw 701 rotates, it can drive the two sets of connecting seats 801 to move relatively by cooperating with the threads, thereby adjusting the distance between the two sets of connecting seats 801, enabling the two sets of connecting seats 801 to cooperate with the two arc-shaped clamping plates 802 to clamp blades of different thicknesses, and improving the applicable range of the wind power blade strength detection device.

[0045] In one embodiment, for the above-mentioned fixed frame plate 2, a T-shaped groove 9 is formed on one side of the fixed frame plate 2, and a T-shaped block 10 is slidably arranged inside the T-shaped groove 9. One side of the T-shaped block 10 is fixedly connected to one side of the first mounting plate 803.

[0046] When the bidirectional screw 701 rotates and drives the first mounting plate 803 to move in cooperation with the connecting seat 801, the first mounting plate 803 can drive the T-shaped block 10 fixedly connected to one side thereof to move. Since the surface of the T-shaped block 10 is slidably arranged inside the T-shaped groove 9, the T-shaped block 10 can slide inside the T-shaped groove 9 during the movement. At the same time, the arrangement of the T-shaped groove 9 and the T-shaped block 10 can enhance the support strength of the first mounting plate 803, thereby improving the stability of the first mounting plate 803.

[0047] In one embodiment, for the above-mentioned rotating shaft 501, a support seat 11 is rotatably arranged on the outer surface of the rotating shaft 501, and one side of the support seat 11 is fixedly connected to one side of the support frame 301.

[0048] The support seat 11 is fixedly arranged on one side of the support frame 301, and the inside of the support seat 11 is rotatably arranged on the outer surface of the rotating shaft 501. The support seat 11 can provide a certain supporting force to the outer surface of the rotating shaft 501, thereby improving the stability of the rotating shaft 501 during the transmission process.

[0049] In summary, by means of the above technical solution of the present utility model, the wind power generation blade sample to be detected is placed on the top of the abutting block 808, and then the second crank 702 is rotated to drive the bidirectional screw 701 to rotate. The bidirectional screw 701 drives the two connecting seats 801 to move relatively. The connecting seat 801 drives the first mounting plate 803 to move. The first mounting plate 803 drives the arc-shaped fixing plate 804 to move. The arc-shaped fixing plate 804 drives the arc-shaped clamping plate 802 to move. The arc-shaped clamping plate 802 drives the mounting block 807 to move. The mounting block 807 drives the abutting block 808 to contact the surface of the wind power generation blade to be detected, thereby fixing the position of the wind power generation blade. When the fixed position is the arc surface of the wind power generation blade, one set of abutting blocks 808 first contacts the surface of the wind power generation blade. Under the continuous movement of the arc-shaped clamping plate 802, the arc-shaped clamping plate 802 slides on the outer surface of the arc-shaped slider 805 in cooperation with the arc-shaped chute 806. Thus, the arc-shaped clamping plate 802 can drive the other set of abutting blocks 808 to contact the surface of the wind power generation blade, thereby completing the fixation of the wind power generation blade. Then, the air cylinder 401 is started to drive the mounting seat 402 to move downward. The mounting seat 402 drives the second mounting plate 403 to move. The second mounting plate 403 drives the hardness tester 404 to move. The hardness tester 404 drives the indenter 405 to contact the surface of the wind power generation blade. Then, the pressure data displayed by the hardness tester 404 is recorded to complete the strength detection of the blade. Then, the first crank 503 is rotated to drive the rotating shaft 501 to rotate. The rotating shaft 501 drives the first bevel gear 504 to rotate, so that the first bevel gear 504 drives the second bevel gear 505 to rotate. The second bevel gear 505 drives the lead screw 502 to rotate. Since the surface of the lead screw 502 is threadedly arranged with the inside of the moving plate 304, when the lead screw 502 rotates, it can drive the moving plate 304 to move, thereby adjusting the position of the moving plate 304. Since the top of the strength detection assembly 4 is fixedly installed with the bottom end of the moving plate 304, the moving plate 304 can drive the strength detection assembly 4 to move, thereby performing strength detection on different positions on the blade.

[0050] Through the above technical solutions: 1. Place the wind power generation blade sample to be detected on the top of the abutting block 808. Drive the adjustment assembly 7 to drive the two connecting seats 801 to move relatively. The connecting seat 801 drives the first mounting plate 803 and the arc-shaped fixing plate 804 to move. Since the arc-shaped fixing plate 804 cooperates with the arc-shaped slider 805 and the arc-shaped chute 806 to drive the arc-shaped clamping plate 802 to move, the arc-shaped clamping plate 802 cooperates with the mounting block 807 to drive the abutting block 808 to contact the surface of the wind power generation blade to be detected, completing the fixation. When the fixation position is the arc surface of the wind power generation blade, make one set of abutting blocks 808 first contact the surface of the wind power generation blade. Under the continuous movement of the arc-shaped clamping plate 802, the arc-shaped clamping plate 802 cooperates with the arc-shaped chute 806 to slide on the outer surface of the arc-shaped slider 805. Then, the arc-shaped clamping plate 802 can drive the other set of abutting blocks 808 to contact the surface of the wind power generation blade, thereby completing the fixation of the wind power generation blade. Furthermore, the two sets of abutting blocks 808 can be completely attached to its surface, avoiding shaking and improving the stability during blade fixation. 2. Rotate the second crank 702 to drive the bidirectional screw 701 fixedly connected inside it to rotate. Since the thread surfaces of the bidirectional screw 701 are internally threaded with the two connecting seats 801, when the bidirectional screw 701 rotates, it can drive the two connecting seats 801 to move relatively by cooperating with the threads, thereby adjusting the distance between the two connecting seats 801, enabling the two connecting seats 801 to cooperate with the two arc-shaped clamping plates 802 to clamp blades of different thicknesses, improving the applicable range of the wind power generation blade strength detection device.
