Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation detection, in particular to a portable gear wear detection device for a wind power generator. Background Art

[0002] Wind power generation is a way of converting wind energy into electrical energy. As a clean, pollution-free, renewable energy source, it is increasingly gaining attention around the world. Wind power generation technology has advantages such as environmental protection and huge wind energy reserves, and therefore has been widely used around the world.

[0003] When detecting gear wear of wind turbines, the purpose of wear detection is basically achieved by adsorbing a vibration sensor on the gear box and analyzing the vibration during operation when the gear wear is detected. Since the sensor is directly adsorbed on the gear box and needs to be constantly moved, when the motor's gear shaft is running, the sensor is easily affected by the vibration of the gear shaft box itself or the vibration of the external environment, which makes it difficult to accurately and intuitively reflect the gear wear. It is easily interfered with by the external environment and the judgment of gear wear, affecting the authenticity and stability of the sensor's detection data during detection, affecting the detection efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a portable gear wear detection device for a wind turbine generator to solve the problems raised in the above background technology.

[0007] A vibration mechanism is installed inside the main body and is used to cover the surface of the gear shaft;

[0008] An auxiliary mechanism is installed inside the vibration mechanism and is used to increase the friction between the gear shaft and the vibration mechanism when the gear shaft rotates;

[0009] The closure of the main body enables the vibration mechanism to drive the auxiliary mechanism to cover the surface of the gear shaft, and the auxiliary mechanism can increase the friction between the gear shaft and the vibration mechanism when the gear shaft rotates.

[0010] Furthermore, the main body includes two arc-shaped semicircular plates rotatably connected to the top of the main body, and a circular groove is formed on one side of the main body and the arc-shaped semicircular plates near the middle of the main body. The main body includes:

[0011] A detection mechanism is provided on the outside of the main body and is used to receive a vibration signal;

[0012] The rotating mechanism is arranged inside the main body and is used to cover the gear shaft.

[0013] Furthermore, the vibration mechanism includes a plurality of semicircular guide plates arranged inside the main body, and the vibration mechanism includes:

[0014] The fixing component is fixedly arranged inside the semicircular guide plate.

[0015] Furthermore, the auxiliary agencies include:

[0016] The opening and closing mechanism is arranged inside the fixing component.

[0017] Furthermore, the detection mechanism includes a detection handle provided on the outer surface of the main body, the top of the detection handle is fixedly connected to a signal transmission line, and an end of the signal transmission line away from the detection handle is fixedly connected to a vibration sensor;

[0018] Among them, the side wall of the main body is vibratedly connected with two buckles, and the buckles are clamped to the arc-shaped semicircular plate.

[0019] Furthermore, the rotating mechanism includes two semicircular plates rotatably connected between two arc-shaped semicircular plates, and the top semicircular plate is fixedly connected to the vibration sensor.

[0020] Furthermore, a bending spring is fixedly connected to the outer surface of the top semicircular plate, and the end of the bending spring away from the semicircular plate is fixedly connected to the side wall of the main body. Several C-shaped plates are fixedly connected to the left and right sides of the semicircular plate, and the several C-shaped plates are distributed at equal angles.

[0021] Furthermore, the fixing assembly includes a semicircular frame fixedly connected to the inner wall of the semicircular guide plate, a plurality of torsion springs are fixedly connected between the two semicircular frames, and a plurality of rectangular grooves are opened on the outer surface of the semicircular frame. Furthermore, a placement groove is opened on the inner wall of the semicircular frame;

[0022] Wherein, the semicircular guide plate is slidably connected to the outer surfaces of a plurality of C-shaped plates.

[0023] Furthermore, the opening and closing mechanism includes a triangular bar slidably connected to the inside of the rectangular groove, and a curved folding plate is provided on the side of several triangular bars away from the semicircular plate, and the front and back sides of the curved folding plate are fixedly connected to the inner wall of the placement groove.

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention, through the closure between the arc-shaped semicircular plate and the main body, can enable multiple semicircular frames to form two circular frames on the surface of the gear shaft and rotate with the gear shaft. When the circular frame rotates, the multiple triangular bars will form multiple points of contact with the inner wall of the semicircular plate when the gear shaft wears and vibrates, and can form multiple vibration signals in the semicircular plate when the gear shaft vibrates. At the same time, the contact friction between the semicircular frame and the semicircular plate can drive the semicircular plate to rotate slightly and stretch the bending spring, which can more directly transmit the tiny shaking of the gear shaft caused by gear wear to the vibration sensor, and can further amplify the vibration change, so that the sensor can detect more obvious and accurate signal values, thereby improving the sensitivity of gear wear detection. The stretching degree of the bending spring can intuitively reflect the change of gear shaft vibration, so that the operator can preliminarily judge the wear state of the gear by observing the stretching state of the bending spring, and thus take corresponding maintenance measures in time, thereby enhancing the accuracy of detection.

[0026] 2. The present invention, through the contact between the semicircular frame and multiple triangular bars and the semicircular plate, the triangular bars will squeeze the corners of the arc-shaped folding plate, so that the arc-shaped folding plate is pushed to both sides with the squeezing point as the center. At this time, the two ends of the arc-shaped folding plate will form a stacked state, and the expansion of the arc-shaped folding plate when squeezed by the triangular bars can contact the surface of the gear shaft. The squeezing point of the arc-shaped folding plate is combined with the stacking of the two ends to increase the friction area between the semicircular frame and the gear shaft through the change of the arc-shaped folding plate, and reduce the change in the speed of rotation of the gear shaft. The relative sliding or jumping between the semicircular frame and the gear shaft caused by the large friction force formed between the semicircular frame and the semicircular plate is reduced, and the inaccurate vibration transmission caused by the sliding between the semicircular frame and the gear shaft is reduced, which affects the accuracy of the signal during detection by the vibration sensor and interferes with the judgment of gear wear, thereby improving the authenticity and stability of subsequent detection and improving detection efficiency.

[0027] 3. The present invention, through the expansion of the middle part of the arc-shaped folding plate and the stacking of the two ends, will cause the two circular frames to rotate with the gear shaft under the condition of increased friction, and multiple torsion springs will form a certain torsion between the two semicircular frames and accumulate a certain mechanical power, thereby pulling the semicircular frames, so that the two circular frames drive the multiple triangular bars to be horizontal and maintain the spacing between the two circular frames. Subsequently, through the mechanical power of the torsion spring torsion, the situation in which the multiple triangular bars on the semicircular frames are misaligned or the spacing between the semicircular frames is changed when the friction between the two circular frames is increased can be reduced, and the situation in which the vibration points in the semicircular plate are disordered when the semicircular frame vibrates with the rotation of the gear shaft due to the misalignment between the multiple triangular bars on the two circular frames can be reduced, resulting in abnormal and inaccurate detection by the vibration sensor during detection, thereby enhancing the detection quality and the reliability of the detection data.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1 - Figure 8 As shown, the present invention is a portable gear wear detection device for a wind turbine, comprising a main body 1 and a gear shaft 4. The top of the main body 1 is semicircular, and further comprises;

[0042] The vibration mechanism 2 is installed inside the main body 1 and is used to cover the surface of the gear shaft 4;

[0043] The auxiliary mechanism 3 is installed inside the vibration mechanism 2 and is used to increase the friction between the gear shaft 4 and the vibration mechanism 2 when the gear shaft 4 rotates;

[0044] Among them, by closing the main body 1, the vibration mechanism 2 can drive the auxiliary mechanism 3 to cover the surface of the gear shaft 4. The auxiliary mechanism 3 can increase the friction between the gear shaft 4 and the vibration mechanism 2 when the gear shaft 4 rotates, thereby increasing the contact area between the gear shaft 4 and the vibration mechanism 2.

[0045] The main body 1 includes two arc-shaped semicircular plates 114 rotatably connected to the top of the main body 1. A circular groove 101 is formed on one side of the main body 1 and the arc-shaped semicircular plates 114 near the middle of the main body 1. The main body 1 includes:

[0046] The detection mechanism 11 is arranged outside the main body 1 and is used to receive the vibration signal;

[0047] The rotating mechanism 12 is arranged inside the main body 1 and is used to cover the gear shaft 4.

[0048] The vibration mechanism 2 includes a plurality of semicircular guide plates 211 arranged inside the main body 1. The vibration mechanism 2 includes:

[0049] The fixing component 21 is fixedly arranged inside the semicircular guide plate 211. The rotation of the fixing component 21 can increase and transmit the vibration signal when the gear on the gear shaft 4 is worn.

[0050] Auxiliary mechanism 3 includes:

[0051] The opening and closing mechanism 31 is disposed inside the fixing assembly 21 .

[0052] The detection mechanism 11 includes a detection handle 111 provided on the outer surface of the main body 1. The top of the detection handle 111 is fixedly connected to a signal transmission line 112. The end of the signal transmission line 112 away from the detection handle 111 is fixedly connected to a vibration sensor 113.

[0053] Among them, the side wall of the main body 1 is vibratingly connected to two clips 115, and the clips 115 are clipped to the arc-shaped semicircular plate 114. The contact friction between the semicircular frame 212 and the semicircular plate 121 can drive the semicircular plate 121 to rotate slightly and stretch the bending spring 122.

[0054] The rotating mechanism 12 includes two semicircular plates 121 rotatably connected between two arc-shaped semicircular plates 114. The top semicircular plate 121 is fixedly connected to the vibration sensor 113, which can transmit the slight shaking of the gear shaft 4 caused by gear wear more directly to the vibration sensor 113, and can further amplify the vibration changes.

[0055] A bending spring 122 is fixedly connected to the outer surface of the top semicircular plate 121, and the end of the bending spring 122 away from the semicircular plate 121 is fixedly connected to the side wall of the main body 1. A plurality of C-shaped plates 123 are fixedly connected to the left and right sides of the semicircular plate 121. The plurality of C-shaped plates 123 are distributed at equal angles, which can more directly transmit the slight shaking of the gear shaft 4 caused by gear wear to the vibration sensor 113, and can further amplify the vibration changes.

[0056] The fixing assembly 21 includes a semicircular frame 212 fixedly connected to the inner wall of the semicircular guide plate 211, and a plurality of torsion springs 213 are fixedly connected between the two semicircular frames 212. The outer surface of the semicircular frame 212 is provided with a plurality of rectangular grooves to reduce the relative sliding or jumping between the semicircular frame 212 and the gear shaft 4 due to the large friction force formed between the semicircular frame 212 and the semicircular plate 121 when the speed of rotation of the gear shaft 4 changes.

[0057] The inner wall of the semicircular frame 212 is provided with a placement groove 214;

[0058] Among them, the semicircular guide plate 211 is slidably connected to the outer surface of several C-shaped plates 123, and then the mechanical power of the torsion spring 213 when twisted can reduce the situation where the two circular frames increase the friction and cause the multiple triangular bars 311 on the semicircular frame 212 to become misaligned or the spacing between the semicircular frames 212 to change.

[0059] The opening and closing mechanism 31 includes a triangular bar 311 slidably connected to the inside of the rectangular groove, and a curved folding plate 312 is provided on the side of the triangular bars 311 away from the semicircular plate 121. The front and back sides of the curved folding plate 312 are fixedly connected to the inner wall of the placement groove 214. Through the contact between the semicircular frame 212 and multiple triangular bars 311 and the semicircular plate 121, the triangular bar 311 will squeeze the corners of the curved folding plate 312, so that the curved folding plate 312 is pushed to both sides with the squeezing point as the center. At this time, the two ends of the curved folding plate 312 will form a stacked state.

[0060] When in use, first open the buckle 115, then the arc-shaped semicircular plate 114 and the main body 1 are opened and closed, and then the main body 1 and the arc-shaped semicircular plate 114 are respectively put on the surface of the gear shaft 4 and the arc-shaped semicircular plate 114 and the main body 1 are closed by the buckle 115, covering the surface of the gear shaft 4, and then the gear shaft 4 is rotated inside the main body 1. When the gear on the gear shaft 4 meshes with the gear inside the gear box and wears, the wear of the gear on the gear shaft 4 will cause it to vibrate when the gear shaft 4 rotates. When the gear shaft 4 vibrates, the vibration sensor 113 will detect the vibration generated by the main body 1 through the semicircular plate 121 and transmit it to the detection mechanism 11 for analysis, so as to achieve the purpose of detecting the gear wear on the gear shaft 4.

[0061] When the arc-shaped semicircular plate 114 is closed with the main body 1, the closing of the arc-shaped semicircular plate 114 will cause the multiple semicircular frames 212 to form two circular frames on the surface of the gear shaft 4. At this time, the formation of the circular frames will fit into the surface of the gear shaft 4 and rotate with the rotation of the gear shaft 4. When the semicircular frame 212 forming the circular frame rotates, it will drive the multiple triangular bars 311 to rotate synchronously inside the semicircular plate 121. When the gear shaft 4 vibrates due to wear, the vibration of the gear shaft 4 will drive the triangular bars 311 to vibrate synchronously inside the semicircular plate 121 through the semicircular frame 212. When the gear shaft 4 drives the triangular bars 311 to vibrate, the multiple triangular bars 311 will make multiple points of contact with the inner wall of the semicircular plate 121. At this time, the point-to-surface contact formed by the multiple triangular bars 311 and the inner wall of the semicircular plate 121 can generate multiple vibration signals on the inner wall of the semicircular plate 121 when the gear shaft 4 vibrates due to wear. At the same time, when the gear shaft 4 vibrates due to wear, When the movable semicircular frame 212 contacts the inner wall of the semicircular plate 121, the contact friction between the semicircular frame 212 and the semicircular plate 121 can make the semicircular frame 212 drive the semicircular plate 121 to rotate slightly as the gear shaft 4 rotates. When the semicircular plate 121 rotates, the bending spring 122 is stretched. Through the synchronous rotation of the semicircular frame 212 and the gear shaft 4, the slight shaking of the gear shaft 4 caused by gear wear can be more directly transmitted to the semicircular plate 121 and the vibration sensor 113 on the semicircular plate 121, which can further amplify the vibration changes, so that the sensor can detect more obvious and accurate signal values, thereby improving the sensitivity of gear wear detection. The stretching degree of the bending spring 122 can intuitively reflect the changes in the vibration of the gear shaft 4, so that the operator can preliminarily judge the wear state of the gear by observing the stretching state of the bending spring 122, so as to take corresponding maintenance measures in time, thereby enhancing the accuracy of detection.

[0062] When the semicircular frame 212 drives the multiple triangular bars 311 to vibrate and rotate as the gear shaft 4 rotates, the semicircular frame 212 drives the triangular bars 311 to contact the inner wall of the semicircular plate 121 when the gear shaft 4 vibrates. When the multiple triangular bars 311 contact the inner wall of the semicircular plate 121, the triangular bars 311 will squeeze the corners of the arc-shaped folding plate 312 under the pressure of the inner wall of the semicircular plate 121. When the corners of the arc-shaped folding plate 312 are squeezed, the arc-shaped folding plate 312 will be pushed to both sides with the squeezing point as the center. At this time, the two sides of the arc-shaped folding plate 312 will form a stacked state when pushed. At the same time, when the arc-shaped folding plate 312 is squeezed by the triangular bars 311, the squeezing point of the arc-shaped folding plate 312 can contact the surface of the gear shaft 4 when it is unfolded. When the extrusion part of the folding plate 312 contacts the surface of the gear shaft 4 after unfolding, the stacking of the two ends of the arc-shaped folding plate 312 can increase the friction area between the semicircular frame 212 and the gear shaft 4 through the change of the arc-shaped folding plate 312, and reduce the relative sliding or jumping between the semicircular frame 212 and the gear shaft 4 due to the large friction force formed between the semicircular frame 212 and the semicircular plate 121 when the speed of rotation of the gear shaft 4 changes, thereby reducing the inaccurate vibration transmission caused by the sliding between the semicircular frame 212 and the gear shaft 4, affecting the accuracy of the signal during detection by the vibration sensor 113 and interfering with the judgment of gear wear, thereby improving the authenticity and stability of subsequent detection and improving detection efficiency.

[0063] When the middle part of the arc-shaped folding plate 312 is unfolded and the two ends are stacked to increase the friction area between the semicircular frame 212 and the gear shaft 4, the two semicircular frames 212 forming the circular frame will rotate synchronously with the gear shaft 4 under the increase of friction force. When the two semicircular frames 212 forming the semicircular frame rotate synchronously with the gear shaft 4 under the condition that the friction force between the arc-shaped folding plate 312 and the gear shaft 4 increases, the torsion spring 213 will form a certain torsion between the two semicircular frames 212 and accumulate a certain mechanical power. When multiple torsion springs 213 accumulate mechanical power, the two ends of the torsion spring 213 can pull the semicircular frame 212 connected thereto through the accumulated mechanical power. The pulling of the semicircular frame 212 by the torsion spring 213 can make the two semicircular frames forming the circular frame 212 drives multiple triangular bars 311 to be horizontal and maintain the spacing between the circular frames formed by the two semicircular frames 212. The mechanical power of the torsion spring 213 when torsioning can reduce the situation that the multiple triangular bars 311 on the two semicircular frames 212 forming the circular frames are misaligned or the spacing between the semicircular frames 212 changes as the gear shaft 4 increases and contacts the inner wall of the semicircular plate 121 when the friction between the two semicircular frames 212 increases. It also reduces the situation that the vibration points in the semicircular plate 121 are disordered due to the misalignment between the multiple triangular bars 311 on the two circular frames when the semicircular frame 212 rotates and vibrates with the gear shaft 4, resulting in abnormal and inaccurate detection by the vibration sensor 113 during detection, thereby enhancing the detection quality and reliability of detection data during detection.
