Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to a device for diagnosing and repairing hidden dangers and faults in wind power generation equipment. Background Technology

[0002] Wind power generation equipment is a clean energy device that uses natural wind energy to drive a wind turbine to rotate, and then drives a generator to generate electricity through a transmission system. The main structure of wind power generation equipment includes a rotor, main shaft, speed increaser, generator, nacelle and other parts. During the operation of the equipment, the rotor rotates under the action of wind load, and then transmits the rotation to the speed increaser through the main shaft to drive the generator to run, thereby realizing the conversion of mechanical energy into electrical energy.

[0003] In the structure of wind power generation equipment, the power transmission components are usually connected by flanges. Especially at the connection of transmission components such as the main shaft, speed increaser and generator, the flange connection needs to maintain consistent concentricity at both ends of the axis during operation. However, wind power generation equipment is affected by a variety of factors such as gravity, vibration, alternating stress and changes in ambient temperature. The bolts and nuts at the flange connection are prone to loosening due to vibration, thermal expansion and contraction or stress fatigue, resulting in uneven gaps between flanges and deviations in coaxiality. Over a long period of operation, the stress-bearing components of the connection structure are prone to cracks, deformation or even breakage, posing safety hazards and affecting the normal operation of the equipment.

[0004] Therefore, during the operation of wind power equipment, it is necessary to regularly inspect and maintain its internal flange structure to eliminate faults and potential safety hazards. The existing maintenance methods mainly rely on manual tightening or loosening of nuts one by one using tools such as wrenches and sockets. Since the flange connection is tightly fitted by bolts and nuts through threaded connections, when one of the bolts or nuts is tightened, the other structure will inevitably rotate, making it impossible to tighten or loosen the bolts and nuts. Due to the small internal space of the wind turbine nacelle or tower, the flanges are mostly distributed in the middle of the main shaft and the gearbox, generator and other structures, with limited working space and less than ideal operating angles. During the tightening process, maintenance personnel are prone to dropping tools such as wrenches and sockets due to the unsuitable force angle, which can cause injury and affect maintenance efficiency.

[0011] Preferably, a brake ring is provided on the outer periphery of the first positioning hole opposite to the fixing groove. The brake ring is fixedly connected to the positioning plate. A guide hole is provided on the outer periphery of the brake ring. The guide hole passes through the side wall of the brake ring radially and communicates with the first positioning hole. A pin is threadedly connected to the guide hole.

[0012] Preferably, one end of the pin is provided with a driving block, and the end face of the driving block is provided with a driving groove that is concave in the radial direction of the pin, and the other end of the pin passes through the guide hole and abuts against the side wall of the first sleeve.

This utility model uses a positioning plate and a clamping plate to form an adjustable clamping structure to fix and clamp the flange at both ends. A first sleeve and a second sleeve are respectively provided on the positioning plate and the clamping plate. The first sleeve and the second sleeve form a snap-fit ​​structure with the bolts and nuts located at both ends of the flange. The positioning plate is provided with a pin that abuts against the first sleeve to limit the rotation of the bolt, so that when the second sleeve drives the nut to rotate, the bolt can remain stationary, and the nut can move along the thread direction to adjust the tightness of the connection between the bolt and the nut.

[0016] 2. This utility model provides a first positioning hole on the positioning plate and a second positioning hole on the clamping plate for guiding and positioning the first and second sleeves respectively. This ensures that during operation, the first and second sleeves are always in the corresponding positioning holes and remain coaxial with the bolts and nuts. This allows them to rotate coaxially under force, effectively preventing the sleeves from swaying or shaking during rotation, and thus preventing the second sleeve from coming off under force when tightening the nut.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example, refer to Figure 1 - Figure 4 A device for troubleshooting and repairing potential hazards and faults in wind power generation equipment includes a positioning plate 1. A guide rod 3 is slidably connected to the positioning plate 1. One end of the guide rod 3 passes through the positioning plate 1 and is connected to a clamping plate 5. A fixing groove 8 is provided between the positioning plate 1 and the clamping plate 5. The clamping plate 5 moves relative to the positioning plate 1, and the width of the fixing groove 8 can be adjusted to accommodate flanges of different thicknesses. The guide rod 3 acts as a guide, ensuring that the clamping plate 5 remains relative to the positioning plate 1 during movement. This fixes the positioning plate 1 and the clamping plate 5 on the axial end faces of the flange connection. A first sleeve 4 is provided on the positioning plate 1. One end of the first sleeve 4 passes through the positioning plate 1 and communicates with the fixing groove 8. Sleeve 4 is used to engage with the nut portion of the bolt connecting the two flanges. The bolt body passes through the two flanges and is connected to the nut, thereby fixing the installation position of the positioning plate 1. A second sleeve 6 is provided on the clamping plate 5. The first sleeve 4 and the second sleeve 6 are coaxial. One end of the second sleeve 6 passes through the clamping plate 5 and communicates with the fixing groove 8. The second sleeve 6 is used to engage with the nut. The other end of the second sleeve 6 is provided with a drive handle 7. In use, by rotating the drive handle 7, the second sleeve 6 is driven to move synchronously with the nut, so that the nut rotates relative to the bolt body portion, thereby tightening or loosening the nut and adjusting the connection between the bolts and nuts between the two flanges.

[0022] Furthermore, the guide rod 3 is provided with an elastic element 2. One end of the elastic element 2 abuts against the end face of the guide rod 3, and the other end abuts against the end face of the positioning plate 1. The elastic element 2 is used to push the guide rod 3 to drive the clamping plate 5 to move toward one end of the positioning plate 1, so that the clamping plate 5 and the positioning plate 1 cooperate and clamp on the opposite axial end faces of the two flanges respectively.

[0023] Furthermore, the guide rod 3 has a connecting end 301 at one end that passes through the positioning plate 1. The connecting end 301 is connected to the clamping plate 5 by a thread, so that the guide rod 3 and the clamping plate 5 can be flexibly disassembled and assembled during use.

[0024] Furthermore, the positioning plate 1 is provided with a first positioning hole 101 that penetrates the positioning plate 1 and communicates with the fixing groove 8. The first sleeve 4 is rotatably disposed in the first positioning hole 101. The first sleeve 4 is used to connect with the nut part of the bolt, thereby fixing the position of the positioning plate 1. By opening the first positioning hole 101 on the positioning plate 1 for positioning and installing the first sleeve 4, the first sleeve 4 can be replaced according to the size of the nut. The first sleeve 4 and the nut are correspondingly engaged to fix the position of the positioning plate 1, thereby avoiding interference caused by the movement of the positioning plate 1 during the process of adjusting the tightness of the nut connection.

[0025] Furthermore, the first sleeve 4 is provided with a first slot 401 at one end relative to the fixed groove 8. In use, the groove size of the first slot 401 corresponds to and matches the outer contour of the nut.

[0026] Furthermore, a brake ring 102 is provided on the outer periphery of the first positioning hole 101 away from the fixed groove 8. The brake ring 102 is fixedly connected to the positioning plate 1. A guide hole 1021 is provided on the outer periphery of the brake ring 102. The guide hole 1021 passes through the side wall of the brake ring 102 radially and communicates with the first positioning hole 101. A pin 9 is threadedly connected in the guide hole 1021.

[0027] Furthermore, one end of the pin 9 is provided with a drive block 901, and the end face of the drive block 901 is provided with a drive groove 902 that is radially recessed along the pin 9, which is used to connect an external tool to turn the pin 9 to move along the guide hole 1021. The other end of the pin 9 passes through the guide hole 1021 and abuts against the side wall of the first sleeve 4, which is used to restrict the rotational freedom of the first sleeve 4, so as to prevent the bolt part from rotating due to the thread and friction when the nut is driven to rotate by the second sleeve 6.

[0028] Furthermore, the clamping plate 5 is provided with a second positioning hole 501 that passes through the clamping plate 5 and communicates with the fixing groove 8. The second sleeve 6 is rotatably disposed in the second positioning hole 501 for positioning the second sleeve 6.

[0029] Furthermore, the second sleeve 6 is provided with a second groove 601 at one end relative to the fixed groove 8. The second groove 601 extends through the second sleeve 6 along the central axis of the second sleeve 6. The second groove 601 is used to engage with the outer contour of the nut. The second groove 601 extends through the second sleeve 6 to prevent the bolt body from interfering with the second groove 601 during use. Thus, by rotating the second sleeve 6, the nut is driven to be screwed in or out along the thread direction of the bolt. The groove size of the second groove 601 corresponds to and matches the outer contour of the nut.

[0030] Working principle: When inspecting the flange connection of the internal transmission structure of the wind power generation equipment, the guide rod 3 slides to move the clamping plate 5 relative to the positioning plate 1, thereby adjusting the width of the fixing groove 8 so that it can accurately engage with the axial end faces of the flange connection. After engagement, the elastic element 2 pulls the clamping plate 5 towards the positioning plate 1, causing the positioning plate 1 and the clamping plate 5 to engage and clamp the flange. The first sleeve 4 is installed in the first positioning hole 101, so that the first slot 401 engages with the nut portion of the bolts on the flange. The first sleeve 4 is engaged and the first sleeve 4 is stopped by the pin 9 to prevent the bolt from rotating. The second sleeve 6 is installed in the second positioning hole 501 on the clamping plate 5 so that the second slot 601 is engaged with the nut. By rotating the drive handle 7 on the outside of the second sleeve 6, the nut can be rotated along the thread direction of the bolt to realize the tightening or loosening of the nut. Thus, during the maintenance process, the tightness of the connection between the two flanges can be adjusted to keep the tightness of each connection point on the flange consistent and avoid transmission jamming.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
