Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine blade testing technology, and in particular to a wind turbine blade surface flatness testing device. Background Technology
[0002] Wind energy is the energy generated by the flow of wind. It is a clean and pollution-free renewable energy source. Wind power generation refers to converting the kinetic energy of wind into electrical energy through wind turbines. Wind turbine blades are the core components of wind turbines. Insufficient surface flatness of wind turbine blades will change the shape of the blades, thereby affecting their aerodynamic performance and reducing the power generation efficiency of the unit. Therefore, it is necessary to test the surface flatness of wind turbine blades.
[0003] A wind turbine blade surface flatness detection device (authorization announcement number: CN219914388U) can clamp and fix the end of the wind turbine blade through a fixing mechanism, thereby achieving clamping and fixing from both ends of the wind turbine blade. This facilitates the movement of the connecting bracket to drive the detector, enabling automatic movement of the detector to detect the flatness of the wind turbine blade surface.
[0004] However, this wind turbine blade surface flatness detection device has some shortcomings in actual use: because the ends of the wind turbine blades are flat and thin, this method of clamping and fixing the wind turbine blades from both ends is not convenient for achieving stable clamping and fixing of the wind turbine blades. The flat part at the end of the wind turbine blade is prone to breakage during the clamping process, which affects the detector's ability to detect the surface flatness of the wind turbine blades. Therefore, we have proposed this utility model to solve the above problems. Utility Model Content

A deflection groove is formed on one side of the testing base, and a convex rod support is rotatably mounted within the deflection groove. An internal toothed ring is fixedly mounted on the inner wall of one side of the convex rod support. A deflection drive mechanism for the internal toothed ring is provided on the top side of the testing base. The wind turbine blade shell is sleeved on the convex rod support. A translation chamber is formed inside the convex rod support. Multiple side openings are formed on the outer surface of the convex rod support. The translation chamber is provided with... The device includes an inner clamping mechanism for the side opening, a clamping drive mechanism for the inner clamping mechanism on one side of the convex rod support, an outer clamping mechanism for the wind turbine blade shell on one side of the convex rod support, an auxiliary support mechanism for the wind turbine blade shell on the top side of the testing base, two translation slots on the inner wall of the testing base, a translation frame movably installed in the two translation slots, a detector on the top side of the translation frame, and a translation drive mechanism for the translation frame on one side of the testing base.
[0008] Preferably, the deflection drive mechanism includes a first motor and a gear column. The first motor is fixedly installed on the top side of the detection base, and the gear column is fixedly installed on the output shaft of the first motor. The gear column meshes with the internal gear ring cylinder. By starting the first motor, the gear column drives the internal gear ring cylinder on the convex rod support to rotate, thereby driving the wind turbine blade shell that is clamped and fixed to deflect slowly, which facilitates the detection of the flatness of the wind turbine blade shell surface with the detector.
[0009] Preferably, the inner clamping mechanism includes a translation seat, an inner clamping plate, and a hinge plate. Multiple translation seats are fixedly installed in the translation chamber, and multiple inner clamping plates are movably installed in multiple side openings. The multiple inner clamping plates are clamped on the inner wall of the wind turbine blade shell. The translation seat and the inner clamping plate are hinged together by the same hinge plate. Under the hinge action of multiple sets of hinge plates, the three sets of multiple inner clamping plates are simultaneously driven to unfold outward, so as to realize the clamping of the wind turbine blade shell from the inside of one end of the wind turbine blade shell through the three sets of multiple inner clamping plates.
[0010] Preferably, the clamping drive mechanism includes a second motor, a bidirectional threaded rod, a first threaded groove, and a second threaded groove. The second motor is fixedly installed on one side of the convex rod support. The output shaft of the second motor is fixedly installed with the bidirectional threaded rod. The bidirectional threaded rod has three sets of first threaded grooves and second threaded grooves. The first threaded grooves and second threaded grooves on the bidirectional threaded rod respectively thread through the corresponding translation seats. By starting the second motor, the bidirectional threaded rod is driven to rotate, thereby synchronously driving the three sets of corresponding translation seats in the convex rod support to move closer to each other.
[0011] Preferably, the external clamping mechanism includes an arc-shaped side plate, a first hydraulic rod, and an external clamping plate. Multiple arc-shaped side plates are fixedly installed on one side of the convex rod support seat. Two first hydraulic rods are fixedly installed on the inner wall of the arc-shaped side plate. The output ends of the two first hydraulic rods are fixedly installed with the same external clamping plate. The external clamping plate clamps onto the wind turbine blade shell. The external clamping mechanism synchronously drives multiple sets of external clamping plates to clamp the wind turbine blade shell from the outside of one end of the wind turbine blade shell.
[0012] Preferably, the auxiliary support mechanism includes a second hydraulic rod and an auxiliary support arc plate. Two second hydraulic rods are fixedly installed on the top side of the testing base, and each of the output ends of the two second hydraulic rods is provided with an auxiliary support arc plate. The two auxiliary support arc plates abut against the bottom of one end of the wind turbine blade housing. By activating the two second hydraulic rods, the two auxiliary support arc plates are driven to rise and abut against the bottom of the other end of the wind turbine blade housing, thus playing an auxiliary support role.
[0013] Preferably, the translation drive mechanism includes a third motor and a translation threaded rod. The third motor is fixedly installed on one side of the detection base. One end of the translation threaded rod is fixedly installed on the output shaft of the third motor. The other end of the translation threaded rod is threaded through the outside of the translation frame and rotatably installed on the inner wall of one side of the detection base. The third motor drives the translation threaded rod to rotate, so that the translation frame can be adjusted horizontally within the two translation slots on the detection base.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This wind turbine blade surface flatness detection device, through a clamping drive mechanism in conjunction with an inner clamping mechanism, clamps the wind turbine blade shell from the inside of one end using three sets of multiple inner clamping plates. Simultaneously, an outer clamping mechanism drives multiple sets of outer clamping plates from the outside of one end of the wind turbine blade shell to clamp it, thereby securing the main body of the wind turbine blade shell. An auxiliary support mechanism provides additional support to the bottom of the other end of the wind turbine blade shell. This wind turbine blade surface flatness detection device prevents the wind turbine blade from breaking during the surface flatness detection process, ensuring the normal operation of the detection.

[0030] In use: When checking the flatness of the surface of the wind turbine blade housing 2, the wind turbine blade housing 2 is hoisted using hoisting equipment, so that one end of the wind turbine blade housing 2 is inserted into the convex rod support seat 4. Then, the second motor 13 is started by venting, which drives the bidirectional threaded rod 14 to rotate. This, in turn, drives the three sets of corresponding two translation seats 10 inside the convex rod support seat 4 to move closer to each other. Under the hinge action of multiple sets of hinge plates 12, the three sets of multiple inner clamping plates 11 are simultaneously driven to unfold outward, so that the wind turbine blade housing 2 is clamped from the inside of one end of the wind turbine blade housing 2 through the three sets of multiple inner clamping plates 11. Then, by starting multiple sets of first hydraulic rods 18, multiple sets of outer clamping plates 19 are simultaneously driven to clamp the wind turbine blade housing 2 from the outside of one end of the wind turbine blade housing 2, thereby clamping the main body of the wind turbine blade housing 2. After fixing, by activating the two second hydraulic rods 20, the two auxiliary support arc plates 21 are driven to rise and abut against the bottom position of the other end of the wind turbine blade housing 2, which plays an auxiliary support role. By activating the third motor 25, the translation threaded rod 26 is driven to rotate, so that the translation frame 23 moves in the two translation slots 22 on the detection base 1. The flatness detection of the surface of the wind turbine blade housing 2 is realized by the detector 24 on the top side of the translation frame 23. By activating the first motor 6, the gear column 7 drives the internal gear ring cylinder 5 on the convex rod support seat 4 to rotate, thereby driving the fixed wind turbine blade housing 2 to slowly deflect, so as to cooperate with the detector 24 to realize a comprehensive flatness detection of the surface of the wind turbine blade housing 2. The wind turbine blade surface flatness detection device in this case improves the efficiency of flatness detection of the surface of the wind turbine blade housing 2.
