Abstract
Description
Technical Field
[0001] This utility model relates to the field of cross-flow wind turbine technology, and in particular to a fully automatic balancing probe device. Background Technology
[0002] During the manufacturing process of cross-flow wind turbines, limitations imposed by factors such as technological level and the precision of processing equipment often result in a certain degree of weight imbalance. To ensure stable operation, dynamic balancing correction is necessary, commonly achieved by inserting counterweights into the turbine blades. Currently, this counterweight insertion operation is largely manual, resulting in high labor costs and low efficiency. Although some fully automated dynamic balancing equipment can perform the insertion operation, the positioning accuracy of the counterweights remains insufficient, easily leading to the counterweights being mistakenly inserted into the gap between two blades. This necessitates readjusting the turbine position and performing a second insertion, further impacting production efficiency. Utility Model Content

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] According to some embodiments of this utility model, refer to Figures 1 to 4The fully automatic balancing probe device includes a mounting base 100, a movable base 200, and a detection component 300. The mounting base 100 is equipped with a drive component 110, which is either a drive cylinder or a push rod motor, with its drive end facing forward. The movable base 200 is fixedly connected to the drive end of the drive component 110. The detection component 300 includes a swing base 320 and a probe 310. The swing base 320 is rotatably connected to the movable base 200, and the probe 310 is retractably connected to the swing base 320, with its front end located at the front of the swing base 320. The drive component 110 can drive the movable base 200 to move, thereby moving the probe 310 in a front-back direction. A first sensor 330 is located at the rear end of the swing base 320, and a second sensor 210 is located on the movable base 200. Retracting the probe 310 relative to the swing base 320 triggers the first sensor 330 at its rear end. The rotation of the pendulum 320 relative to the movable seat 200 can trigger the second sensor 210.
[0025] When positioning the blades of the wind turbine, the drive component 110 drives the moving base 200 and the detection component 300 to move forward. When the probe 310 moves forward a certain distance and is located in the gap between the two blades, the wind turbine rotates to drive the blades to rotate. The blades abut against the outer peripheral wall of the probe 310 and continue to apply force to the probe 310, so that the blades drive the probe 310 and the swing base 320 to rotate. After the swing base 320 rotates a certain angle, it triggers the second sensor 210, and the wind turbine stops rotating, thus completing the positioning of the blades.
[0026] If the probe 310 moves forward and directly abuts against the blade, under the reaction force of the blade, the probe 310 retracts backward, thereby triggering the first sensor 330 at the rear end of the probe 310. Then, the drive component 110 drives the moving seat 200 and the detection component 300 to move backward to the initial position. After the wind turbine rotates a certain angle, it stops. The drive component 110 then drives the moving seat 200 and the detection component 300 to move forward again, so that the probe 310 moves forward a certain distance and is located in the gap between the two blades. The wind turbine rotates again to drive the blade to rotate. The blade abuts against the outer peripheral wall of the probe 310 and continues to apply force to the probe 310, so that the blade drives the probe 310 and the swing seat 320 to rotate. After the swing seat 320 rotates a certain angle, it triggers the second sensor 210, and the wind turbine stops rotating, thereby completing the positioning of the blade.
[0027] Understandably, the first sensor 330 is responsible for monitoring the linear retraction of the probe 310, while the second sensor 210 monitors the rotation of the pendulum 320.
[0028] In the first scenario: the probe 310 moves forward and inserts into the gap between the two blades. After the wind turbine rotates at a certain angle, it triggers the second sensor 210 to complete the positioning.
[0029] In the second scenario: when the probe 310 moves forward and directly touches the blade, it triggers the first sensor 330. The probe 310 then moves backward and, after the wind turbine rotates a certain angle, moves forward again and inserts into the gap between the two blades. After the wind turbine rotates a certain angle, it triggers the second sensor 210 to complete the positioning.
[0030] This ensures that the position of the blades can be captured in both of the above situations, thus providing an absolutely accurate positional reference for the subsequent insertion of counterweight plates, significantly improving the automation level and production efficiency of the fully automatic balancing machine.
[0031] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The rear end of probe 310 is inserted into and slidably connected to the swing base 320. A first return spring 340 is provided inside the swing base 320. The first return spring 340 is sleeved on probe 310, and its front end is connected to probe 310. Specifically, the front end of the first return spring 340 is connected to the rear end face of the step on the outer peripheral wall of probe 310; the rear end of the first return spring 340 is connected to the swing base 320. When the driving component 110 drives the moving base 200, swing base 320, and probe 310 to move forward synchronously, the front end of probe 310 abuts against the blade. Under the reaction force of the blade, probe 310 moves backward relative to the moving base 200. Probe 310 compresses the first return spring 340 and moves backward, causing the rear end of probe 310 to move backward to the trigger position of the first sensor 330. After the first sensor 330 is triggered, it indicates that the blade position has been detected and located. Next, the drive component 110 drives the probe 310 to move backward back to the initial position. The front end of the probe 310 no longer abuts against the blade. The first reset spring 340 applies a forward force to the probe 310, causing the probe 310 to move forward relative to the moving seat 200 to the initial position.
[0032] Preferably, the first sensor 330 is a photoelectric switch sensor. The probe 310 can overcome the backward movement of the first reset spring 340, causing the rear end of the probe 310 to move and trigger the first sensor 330. The photoelectric switch sensor is a non-contact sensor that determines its position by detecting the obstruction or reflection of the light path by the rear end of the probe 310. Compared with traditional mechanical microswitches, photoelectric switches have no physical contact, thus eliminating mechanical wear and resulting in an extremely long service life. Furthermore, they have extremely fast response speeds, enabling more precise capture of the moment the probe 310 reaches the trigger position. They also have high repeatability because their trigger point is a fixed light path opening / closing point, unaffected by fatigue or deformation of mechanical components. The rear end of the probe 310 can be designed as a specific light-shielding plate or reflective surface to cooperate with the operation of the photoelectric switch. For example, in a through-beam photoelectric switch, the rear end of the probe 310 does not obstruct the light path in its initial position, but completely obstructs the light path when retracted to its final position, thereby generating a clear switching signal.
[0033] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The fully automatic balancing probe device also includes a second return spring 220, the two ends of which are connected to the movable seat 200 and the swing seat 320, respectively. In the initial state, the axis of the probe 310 is in the left-right direction. When the driving component 110 moves the movable seat 200, the swing seat 320, and the probe 310 forward, and the probe 310 is inserted between two blades of the wind turbine, the wind turbine rotates, causing the blades to rotate. This causes the blades to drive the probe 310 and the swing seat 320 to overcome the force of the second return spring 220, compressing the second return spring 220. The probe 310 and the swing seat 320 rotate relative to the movable seat 200. When the rear end of the swing seat 320 abuts against and triggers the second sensor 210, it indicates that the position of the positioning blade has been detected. Next, the wind turbine stops rotating, and the drive component 110 drives the moving seat 200, the swing seat 320 and the probe 310 to move backward. After the probe 310 disengages from the blade, the second reset spring 220 drives the swing seat 320 to rotate, so that the swing seat 320 and the probe 310 rotate relative to the moving seat 200 to the initial angle.
[0034] According to some embodiments of this utility model, refer to Figure 3The upper end of the movable base 200 is recessed downwards to form a positioning groove 230. The lower end of the second return spring 220 is inserted into the positioning groove 230 and fixedly connected to the swing base 320. The upper end of the second return spring 220 is connected to the swing base 320. The positioning groove 230 facilitates the assembly and positioning of the second return spring 220. During assembly, only the lower end of the second return spring 220 needs to be placed into the groove, eliminating the need for complex measurements and alignment, thus reducing assembly difficulty and time. At the same time, the sidewall of the positioning groove 230 can restrict the displacement of the second return spring 220 in the non-working direction, ensuring that the force direction of the second return spring 220 is always along the preset direction, thereby ensuring the stability and repeatability of the return torque.
[0035] According to some embodiments of this utility model, refer to Figure 3 A spring plate 350 is fixedly provided at the upper end of the swing base 320. The spring plate 350 is provided with a positioning hole 351. The upper end of the second return spring 220 is inserted into the positioning hole 351 and fixedly connected with the spring plate 350. The positioning hole 351 facilitates the assembly and positioning of the second return spring 220.
[0036] According to some embodiments of this utility model, refer to Figure 3 The second sensor 210 includes a positive electrode 211 and a negative electrode 212, which are spaced apart in the left-right direction. Rotation of the swing base 320 drives the spring 350 to rotate, overcoming the second return spring 220. The positive electrode 211 and negative electrode 212 are electrically connected to the controller. The rear end of the spring 350 is connected to both the positive and negative electrode 211, allowing them to communicate and send feedback to the controller, indicating that the blade has been positioned. When the rear end of the spring 350 simultaneously abuts against both the positive and negative electrode 211, the spring 350 bends due to its elasticity, preventing damage to the positive and negative electrode 211 and ensuring it remains firmly pressed against them, thus preventing poor contact. The positions of the positive electrode 211 and the negative electrode 212 can be interchanged.
[0037] When the pendulum base 320 rotates, the rear end of the spring contact 350 fixed on it sweeps across the positive and negative electrodes 212, eventually contacting both simultaneously to form a circuit and generate a clear electrical signal. The spring contact 350 is typically made of phosphor bronze or beryllium copper, possessing both excellent conductivity and elasticity. After the spring contact 350 contacts the electrode, the pendulum base 320 may continue to rotate a small angle due to inertia or driving force. At this time, the elastic deformation of the spring contact 350 can absorb this excess displacement, effectively preventing rigid collisions from damaging the electrode or the rotation mechanism of the pendulum base 320. The elasticity of the spring contact 350 allows it to adhere tightly to the electrode with a certain pressure, overcoming poor contact problems that may be caused by surface oxidation or minor contaminants, ensuring stable and reliable signal.
[0038] Alternatively, the positive electrode 211 is fixedly connected to the front end of the spring 350, while the negative electrode 212 is fixedly connected to the movable base 200. When the rear end of the spring 350 abuts against the negative electrode 212, the positive electrode 211 and the negative electrode 212 are connected through the spring 350. The positions of the positive electrode 211 and the negative electrode 212 can be interchanged.
[0039] According to some embodiments of this utility model, refer to Figure 3 The upper surface of the swing base 320 is provided with a limiting groove 360. The front end of the spring piece 350 is placed in the limiting groove 360. The left and right side walls of the limiting groove 360 can restrict the movement of the spring piece 350 in the left and right directions. The limiting groove 360 is provided with a threaded hole. The detection component 300 also includes a bolt, which passes through the spring piece 350 and is threadedly connected to the threaded hole, so that the spring piece 350 is relatively fixed to the swing base 320. The limiting groove 360 facilitates the assembly and positioning of the spring piece 350. The left and right side walls of the limiting groove 360 prevent the spring piece 350 from laterally deflecting during operation, ensuring that its rear end can accurately sweep towards the positive and negative electrode plates 212. The connection method of bolt and threaded hole provides a strong and reliable axial clamping force to prevent the spring piece 350 from loosening during use.
[0040] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The movable seat 200 is equipped with a fixed shaft 371 extending in the left-right direction. The swing seat 320 is equipped with a bearing 372, through which the fixed shaft 371 passes and is rotatably connected. The bearing 372 enables the swing seat 320 to have a very small starting torque, so even a weak lateral force applied by the blades can easily drive the swing seat 320 to rotate, thereby greatly improving the trigger sensitivity of the second sensor 210. At the same time, the bearing 372 can also withstand radial and axial loads, ensuring the stability of the rotation center and improving the rotational accuracy and service life of the swing seat 320. Alternatively, a bushing can be used to replace the bearing 372.
[0041] According to some embodiments of this utility model, refer to Figure 4The fully automatic balancing probe device also includes a slide 120 and a frame 130. The slide 120 is slidably connected to the frame 130 in the left-right direction, and the mounting base 100 is rotatably connected to the slide 120. The slide 120 is equipped with a first eccentric locking mechanism and a second eccentric locking mechanism. The first eccentric locking mechanism allows the slide 120 and the frame 130 to be relatively fixed or allows the slide 120 to slide relative to the frame 130. The second eccentric mechanism allows the slide 120 and the mounting base 100 to be relatively fixed or allows the mounting base 100 to rotate relative to the slide 120. Both the first and second eccentric locking mechanisms are eccentric handles. Clamping force is applied or released by rotating an eccentric wheel. Repositioning and locking of the device can be completed by simply turning the locking handle a few times, shortening the time for equipment changeover and debugging, thereby improving the flexible production capacity and overall efficiency of the entire production line.
[0042] The working process of this embodiment includes: In the initial state, the first reset spring 340 pushes the probe 310 to the front end, and the second reset spring 220 stabilizes the swing base 320 at the initial center position.
[0043] The control system is activated, and the drive component 110 drives the moving base 200 and the entire detection component 300 to move at a constant speed towards the wind turbine in the front-to-back direction.
[0044] Two scenarios may occur during this process: Scenario A: The drive component 110 drives the probe 310 forward. The tip of the probe 310 does not contact the blades but enters the gap between the two blades. At this time, the first sensor 330 is not triggered. The drive turbine motor makes the turbine rotate slowly. The side edge of the rotating blades will contact the side wall of the probe 310 and apply a lateral force. This force is transmitted to the pendulum base 320 through the probe 310, causing the pendulum base 320 to overcome the force of the second return spring 220 and deflect around the rotation center formed by the fixed shaft 371 and the bearing 372. When the pendulum base 320 rotates to a preset angle, the conductive spring 350 fixed on it will simultaneously contact the positive electrode 211 and the negative electrode 212 of the second sensor 210, making the circuit conductive and sending a positioning success signal to the controller.
[0045] In the second scenario (B): The drive component 110 drives the probe 310 forward, directly contacting the surface of a wind turbine blade. Under the reaction force generated by the blade, the probe 310 overcomes the elastic force of the first return spring 340 and slides backward relative to the swing base 320. When the rear end of the probe 310 moves to a preset position and triggers the first sensor 330, the controller receives this signal. This signal is "detection path obstructed." Immediately, the controller instructs the drive component 110 to move in the opposite direction, causing the moving base 200 and the entire detection component 300 to retract to their initial positions. The first return spring 340 pushes the probe 310 back to its initial position. Simultaneously, the controller instructs the wind turbine to rotate by a preset angle to offset the current blade position. Subsequently, the drive component 110 drives the probe 310 forward again, allowing the probe 310 to smoothly enter the gap between the blades. The wind turbine motor drives the wind turbine to rotate slowly. The rotating blade edge contacts the sidewall of the probe 310 and applies a lateral force. The force is transmitted to the pendulum base 320 through the probe 310, causing the pendulum base 320 to overcome the force of the second return spring 220 and deflect around the rotation center formed by the fixed shaft 371 and the bearing 372. When the pendulum base 320 rotates to a preset angle, the conductive spring 350 fixed on it will simultaneously contact the positive electrode 211 and the negative electrode 212 of the second sensor 210, making the circuit conductive and sending a positioning success signal to the controller.
[0046] After either scenario A or B, once the controller receives a successful positioning signal, it stops the rotation of the wind turbine and records the precise angle of the turbine at that moment; this angle is the target position for subsequent blade insertion operations. Subsequently, the controller instructs the drive component 110 to move in the reverse direction, causing the entire probe device to retract and detach the probe 310 from the wind turbine. The elastic force of the second return spring 220 immediately pulls the pendulum seat 320 and the probe 310 back to their initial center angle. Finally, a complete blade positioning cycle ends, and the entire probe device automatically returns to its initial state, ready to probe the next position requiring balancing correction.
