Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade monitoring technology, specifically to a wind turbine blade monitoring sensor installation structure. Background Technology

[0002] During the operation of wind turbine units, it is necessary to collect equipment operation data (such as vibration, temperature, etc.) in real time through monitoring sensors to ensure the safe and stable operation of the unit. The installation stability of the sensors directly affects the accuracy and reliability of the monitoring data.

[0003] In the existing technology, the installation structure of wind turbine monitoring sensors often has many shortcomings: some installation structures rely on rigid connection methods such as bolts, which not only makes the installation and disassembly process cumbersome, but also requires a variety of tools and is time-consuming, making it difficult to meet the rapid maintenance needs under the complex operating conditions of wind turbines; some magnetic installation structures simplify the installation process, but the permanent magnet fixing method is not stable enough, and the permanent magnet is prone to displacement or falling off due to long-term vibration of the unit, thus affecting the magnetic attraction effect.

[0004] Therefore, we propose an installation structure for a monitoring sensor on wind turbine blades. Utility Model Content

[0005] The purpose of this invention is to provide an installation structure for a wind turbine blade monitoring sensor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade monitoring sensor mounting structure, comprising a fixed base for fixed installation with the wind turbine blade and a connecting seat for mounting the sensor. The top of the fixed base is integrally provided with a connector, and the top of the fixed base has a connecting groove located outside the connector. A transmission rod located below the connector is rotatably connected to one side of the fixed base. A rotating shaft is rotatably connected inside the connector. One end of the transmission rod is drively connected to the bottom of the rotating shaft, and the other end of the transmission rod is integrally connected to a crank groove extending to the outer circumference of the fixed base. A rotating disk located inside the connector is fixedly mounted on the top of the rotating shaft.

A connecting rod is rotatably connected to the outer circumference of the rotating disk, and the end of the connecting rod is rotatably connected to the end of the fixing pin near the rotating disk. A push-out spring is provided at the end of the fixing pin near the rotating disk. A connecting ring corresponding to the connecting groove is integrally provided at the bottom of the connecting seat, and a fixing hole corresponding to the fixing pin is provided in the middle of the connecting ring.

[0007] Optionally, a first bevel gear is fixedly installed at one end of the transmission rod, and a second bevel gear is fixedly installed at the bottom of the rotating shaft, wherein the second bevel gear meshes with the first bevel gear.

[0008] Optionally, a positioning hole is provided at the bottom of the connecting groove, and a positioning pin corresponding to the positioning hole is integrally provided at the bottom of the connecting ring, wherein the positioning hole and the positioning pin are adapted to each other.

[0009] Optionally, one end of the ejector spring is abutted against the end of the fixing pin, and the other end of the ejector spring is fixedly installed inside the connector. Two sets of ejector springs are symmetrically arranged on the upper and lower sides of the connecting rod.

[0010] Optionally, the top of the connecting seat is provided with bolts for fixed installation with the industrial robot base plate, and the bottom of the outer periphery of the fixed base is provided with fixing feet.

Through the synchronous locking design of multiple fixed pins driven by the meshing of the first and second bevel gears, the wind turbine blade monitoring sensor can be installed and removed without tools. The time required for single-person high-altitude operation is reduced by more than 70% compared with traditional solutions. At the same time, the base plate of the industrial robot is reserved to adapt to the mounting bolt holes, which can be directly equipped with intelligent operation and maintenance robots to complete automated deployment without the need for manual high-altitude operation. This not only greatly reduces the labor cost and high-altitude operation safety risks of blade maintenance and sensor replacement, but also fully adapts to the extreme outdoor conditions of high vibration and high salt spray of wind turbine blades.

[0014] The installation structure of this wind turbine blade monitoring sensor adopts a multi-directional synchronous rigid locking structure inside the connector, which simultaneously engages the connecting ring of the fixing seat from multiple points, completely avoiding the problem of component displacement and detachment after long-term operation.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a wind turbine blade monitoring sensor mounting structure, including a fixed base 1 for fixed installation with the wind turbine blade and a connecting seat 2 for mounting the sensor. A connector 4 is integrally provided on the top of the fixed base 1, and a connecting groove 5 located outside the connector 4 is opened on the top of the fixed base 1. A transmission rod 6 located below the connector 4 is rotatably connected to one side of the fixed base 1. A rotating shaft 7 is rotatably connected inside the connector 4. One end of the transmission rod 6 is connected to the bottom of the rotating shaft 7, and the other end of the transmission rod 6 is integrally connected to a crank groove 3 extending to the outer circumference of the fixed base 1. A rotating disk 8 located inside the connector 4 is fixedly installed on the top of the rotating shaft 7. A guide groove 11 is provided inside the connector 4 around the rotating disk 8, and a fixing pin 10 is slidably connected inside the guide groove 11. A connecting pull rod 9 is rotatably connected to the outer circumference of the rotating disk 8, and the end of the connecting pull rod 9 rotates with the end of the fixing pin 10 near the rotating disk 8. The connection is achieved by providing a push-out spring 12 at one end of the fixed pin 10 near the rotating disk 8, and an integral connecting ring 16 corresponding to the connecting groove 5 at the bottom of the connecting seat 2. The middle of the connecting ring 16 has a fixing hole 17 corresponding to the fixed pin 10. This completely eliminates the cumbersome operation logic of traditional all-bolt rigid connection and solves the problem of easy detachment of ordinary permanent magnet magnetic installation structure. Through the synchronous locking design of multiple fixed pins 10 driven by the meshing of the first bevel gear 14 and the second bevel gear 15, the tool-free quick installation and removal of the wind turbine blade monitoring sensor is realized. The time spent by a single person working at height is reduced by more than 70% compared with the traditional solution. At the same time, the base plate of the industrial robot is reserved to adapt to the mounting bolt hole, which can be directly equipped with an intelligent operation and maintenance robot to complete the automated deployment without the need for manual high-altitude operation. This not only greatly reduces the time cost and high-altitude operation safety risks of blade maintenance and sensor replacement, but also fully adapts to the extreme outdoor working conditions of high vibration and high salt spray of wind turbine blades.

[0019] A first bevel gear 14 is fixedly installed at one end of the transmission rod 6, and a second bevel gear 15 is fixedly installed at the bottom of the rotating shaft 7. The second bevel gear 15 meshes with the first bevel gear 14.

[0020] The bottom of the connecting groove 5 is provided with a positioning hole 13, and the bottom of the connecting ring 16 is integrally provided with a positioning pin 18 corresponding to the positioning hole 13. The positioning hole 13 and the positioning pin 18 are compatible.

[0021] One end of the ejector spring 12 is pressed against the end of the fixed pin 10, and the other end of the ejector spring 12 is fixedly installed inside the connector 4. The two sets of ejector springs 12 are symmetrically arranged on the upper and lower sides of the connecting rod 9.

[0022] The top of the connecting seat 2 is provided with bolts for fixing it to the base plate of the industrial robot, and the bottom of the outer periphery of the fixed base 1 is provided with fixed feet.

[0023] The guide grooves 11 are symmetrically arranged on the upper and lower sides of the connecting rod 9. Two guide grooves 11 form a group, and the upper and lower sides of the fixing pin 10 are slidably connected to the guide grooves 11 respectively.

[0024] The fixed pin 10 is slidably connected to the outer circumference of the connector 4, and the connector 4 is internally inserted into the connecting ring 16. The connector 4 adopts a multi-directional synchronous rigid locking structure inside, which simultaneously engages the connecting ring 16 of the fixed connecting seat 2 from multiple points, completely avoiding the problem of component displacement and detachment after long-term operation. The all-mechanical structure design without electronic components, coupled with IP68 protection capability, can work stably and continuously in a wide temperature range of -40℃ to 70℃. The matching positioning pin 18 and positioning hole 13 alignment structure can realize the circumferential zero-deviation installation of the wind turbine blade monitoring sensor. There will be no shift in the monitoring point even after multiple disassemblies and reassemblies, and the data acquisition benchmark will always be maintained. This ensures the accuracy and consistency of blade monitoring data such as vibration, strain, and temperature from the installation source.

[0025] Working principle: First, fix the fixed base 1 of the wind turbine blade monitoring sensor mounting structure to the preset monitoring point on the wind turbine blade through the fixing feet at the bottom of the outer periphery of the fixed base 1, complete the reference positioning of the fixed base 1, and ensure that the fixed base 1 is completely attached to the surface of the wind turbine blade without any loose gaps.

[0026] The wind turbine blade monitoring sensors to be deployed are pre-fixed to the connecting base 2 using mounting bolts that are compatible with the industrial robot base plate, completing the integrated assembly of the wind turbine blade monitoring sensors and the connecting base 2. Then, the integrally formed connecting ring 16 at the bottom of the connecting base 2 is aligned with the connecting groove 5 on the top of the fixed base 1 outside the plug 4. Simultaneously, the locating pin 18 integrally formed at the bottom of the connecting ring 16 is precisely engaged into the locating hole 13 at the bottom of the connecting groove 5, completing the initial circumferential and radial alignment. At this point, the plug 4 integrally formed at the top of the fixed base 1 is simultaneously inserted into the hollow interior of the connecting ring 16. Then, using a matching tool, the crank handle groove 3 pre-reserved on the side of the fixed base 1 is inserted, and the transmission rod 6 rotatably connected to the side of the fixed base 1 is rotated. The first bevel gear 14, fixedly installed at one end of the moving rod 6, meshes with the second bevel gear 15, which is fixedly installed at the bottom of the rotating shaft 7 inside the connector 4. This drives the rotating shaft 7, which is rotatably connected inside the connector 4, to rotate synchronously. The rotating disk 8, which is fixedly installed at the top of the rotating shaft 7 inside the connector 4, rotates accordingly. This causes the multiple sets of connecting rods 9, which are rotatably connected to the outer circumference of the rotating disk 8, to be pushed outward. This pushes the fixed pin 10, which is slidably connected in the guide groove 11 inside the connector 4, to slide outward synchronously along the guide groove 11. Finally, the end of the fixed pin 10 is completely inserted into the corresponding fixing hole 17 opened on the side wall of the connecting ring 16. At this time, the ejector spring 12 on the side of the fixed pin 10 is synchronously compressed, forming a multi-point rigid lock, thus completing the final fixing of the wind turbine blade monitoring sensor.

[0027] When it is necessary to replace or repair the wind turbine blade monitoring sensor, the transmission rod 6 is rotated in the reverse direction. Through the linkage of the first bevel gear 14 and the second bevel gear 15, the rotating disk 8 at the top of the rotating shaft 7 is rotated in the reverse direction. The connecting rod 9 is pulled inward, releasing the outward pushing force on the fixing pin 10. At this time, the compressed ejector spring 12 releases its elastic force, driving the fixing pin 10 to retract inward along the guide groove 11 inside the connector 4, completely disengaging from the fixing hole 17 on the side wall of the connecting ring 16. The wind turbine blade monitoring sensor can be removed from the fixing base 1 by simply lifting the connecting seat 2 upward. There is no need to disassemble the fixing base 1 that is pre-fixed on the wind turbine blade, which greatly simplifies the subsequent replacement operation.

The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent.
