Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade appearance monitoring technology, specifically an online monitoring system for blades with a regular linear structure. Background Technology

[0002] Wind turbine blades are one of the most basic and critical components of wind turbine generators. Online monitoring refers to the use of various advanced technologies and equipment to monitor the appearance of wind turbine blades in real time, continuously and automatically during the wind turbine production process, in order to ensure the safe operation and stable performance of wind turbine blades in subsequent use and to detect potential problems in a timely manner.

[0003] Currently, online monitoring systems used in wind turbine blade production rely on CCD image sensors to monitor the blade's appearance. The monitoring data is transmitted via wires of varying lengths. While this doesn't affect performance when the wire length is appropriate, longer wires, due to a lack of a regular structure, are prone to damage when dragged on the ground. They are also susceptible to stress that could cause them to detach from the CCD image sensor, thus affecting transmission efficiency and limiting applicability. Therefore, there is a need for an online blade appearance monitoring system that can address these shortcomings and improve performance. Utility Model Content

[0004] The purpose of this invention is to provide an online monitoring system for blades with a well-organized linear structure, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model is an online monitoring system for blades with a regular linear structure, comprising:

[0006] An online appearance monitoring mechanism includes a mounting frame, a mounting groove is provided in the middle of the bottom end of the mounting frame, and a CCD detection sensor is embedded in the top of the inner wall of the mounting groove.

[0007] A line straightening mechanism includes a support fixed to the upper part of the back of the mounting frame. A straightening column is provided on one side of the support, and a limiting ring is provided at the front and rear ends of the outer surface of the straightening column. A support column is symmetrically provided on one side of the front limiting ring. A limiting rope is attached to one end of the support column, and a sleeve is provided at one end of the limiting rope, which extends into one side of the rear limiting ring.

[0008] Furthermore, the support has equidistant positioning posts in the middle and extends into the back of the mounting frame.

[0009] Furthermore, a movable tube is fixed to one side of the support, and a movable column is fitted inside the middle of the movable tube with damping, and one end of the movable column is fixed to the regular column.

[0010] Furthermore, the appearance online monitoring mechanism also includes a bearing that runs through the lower part of the back of the mounting frame, with a rubber protective sleeve fitted inside the middle of the bearing, and electrical wires connected within the mounting frame extending out of the rubber protective sleeve.

[0011] Furthermore, it also includes a movable mounting mechanism, which includes threaded columns symmetrically connected to the front and rear of the upper end of the mounting frame. A sleeve is fitted in the middle of the threaded column, and a longitudinal plate is fixed to the lower part of the outer surface of the sleeve, while a transverse plate is fixed to the upper part of the outer surface of the sleeve.

[0012] Furthermore, the end of the threaded post is threaded with a locking nut, which abuts against the mounting frame.

[0013] Furthermore, a threaded tube is provided through one end of the transverse plate, and the upper and lower ends of the threaded tube are threaded with threaded rings and extend into the transverse plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a wire straightening mechanism to wind and coil the longer portion of the conductor using straightening posts. Limiting rings are fitted at the front and rear ends of the straightening posts with damping sleeves. When the coiled portion of the conductor is small, an inward force can be applied directly to a set of limiting rings, ensuring the structural stability of the straightened conductor. If the straightened guide portion is large, the conductor can be directly wound and coiled using the straightening posts. During subsequent fixing, a limiting rope can be used in conjunction with the resistance force of the limiting rings. The end of the limiting rope is fixed by a support post, a sleeve post, and one side of the limiting rings, acting on the outer surface of the coiled conductor to keep it in a constrained state. This design satisfies the need for conductor straightening without requiring the replacement of straightening posts of different diameters depending on the amount of conductor being coiled, offering strong applicability, meeting various needs, and improving performance.

Detailed Implementation

[0024] 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.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this utility model is an online monitoring system for blades with a regular linear structure, comprising:

[0027] The appearance online monitoring mechanism includes a mounting frame 11, a mounting groove 12 is provided in the middle of the bottom end of the mounting frame 11, and a CCD detection sensor 13 is embedded in the top of the inner wall of the mounting groove 12.

[0028] The mounting frame 11 provides a structural installation environment. The CCD detection sensor 13 is installed and fixed with the mounting slot 12. The CCD detection sensor 13 is used to inspect the appearance of the wind turbine blades during production. The CCD detection sensor 13 is model ICX205.

[0029] The appearance online monitoring mechanism also includes a bearing that runs through the lower part of the back of the mounting frame 11. A rubber protective sleeve is fitted inside the middle of the bearing, and the wires that are electrically connected inside the mounting frame 11 extend out of the rubber protective sleeve.

[0030] The bearing supports the rubber protective sleeve, allowing the wire to rotate while preventing damage from excessive twisting. The rubber protective sleeve protects the wire from bending, and the wire enables power transmission and data transfer.

[0031] The line straightening mechanism includes a support 21 fixed to the upper part of the back of the mounting frame 11. A straightening column 25 is arranged on one side of the support 21, and a limiting ring 26 is provided on the front and rear ends of the outer surface of the straightening column 25. A support column 27 is symmetrically provided on one side of the front limiting ring 26. A limiting rope 28 is attached to one end of the support column 27, and a sleeve 29 is provided on one end of the limiting rope 28, which extends into one side of the rear limiting ring 26.

[0032] Support 21 provides a structural installation environment. The longer portion of the conductor is wound and stored by means of the regular column 25. The limiting ring 26 can structurally limit the wound conductor. The support column 27 is bolted to one end of the limiting rope 28 and the other end of the limiting rope 28 is limited by means of the sleeve column 29. The limiting rope 28 acts on the surface of the conductor through the inside of the limiting rope 28 to complete the structural limitation of the longer wound portion of the conductor.

[0033] Positioning posts 22 are equidistantly provided in the middle of the support 21 and extend into the back of the mounting frame 11;

[0034] The positioning column 22 provides structural fixation for the support 21.

[0035] A movable tube 23 is fixed on one side of the support 21, and a movable column 24 is fitted inside the middle of the movable tube 23 with damping. One end of the movable column 24 is fixed to the regular column 25.

[0036] The damping sleeve of the movable column 24 inside the movable tube 23 can fix the support 21 and the leveling column 25, and the leveling column 25 can be finely adjusted back and forth by means of the expansion and contraction of the movable column 24 inside the movable tube 23.

[0037] Working principle: During the appearance monitoring of the wind turbine blades in production using the CCD detection sensor 13, data transmission and power supply are achieved using wires. When the wire length is appropriate, the straightening post 25 is not needed. When the wire length is long but the required straightening portion is small, the wire is directly wound around the outer surface of the straightening post 25. After straightening, an inward force is applied to the limiting ring 26. The contact between the limiting ring 26 and the wire ensures the stability of the structure. When the wire length is long and the required straightening portion is large, the above straightening and limiting steps are repeated. One end of the limiting rope 28 is bolted to the support post 27, while the other end is limited by the sleeve post 29 and the inner side of a limiting ring 26. The contact force of the limiting rope 28 on the wire ensures the stability of the structure.

[0038] This solution, while ensuring conductor straightening, eliminates the need to replace different diameter straightening posts 25 depending on the amount of conductor being wound, making it highly adaptable, meeting various needs, and improving performance.

[0039] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The movable installation mechanism includes threaded columns 31 symmetrically connected to the front and rear of the upper end of the installation frame 11. A sleeve 33 is sleeved in the middle of the threaded column 31, and a longitudinal plate 34 is fixed to the lower part of the outer surface of the sleeve 33, and a transverse plate 35 is fixed to the upper part of the outer surface of the sleeve 33.

[0041] The end thread of the threaded column 31 is provided with a locking nut 32, which abuts against the mounting frame 11;

[0042] A threaded tube 36 is provided through one end of the transverse plate 35, and threaded rings 37 are threaded at the upper and lower ends of the threaded tube 36 and extend into the transverse plate 35.

[0043] The threaded column 31 is fixed to the longitudinal plate 34 and the transverse plate 35 by means of the sleeve 33. The longitudinal plate 34 and the transverse plate 35 can be adjusted at multiple angles by means of the threaded rotation of the threaded column 31. At the same time, the longitudinal plate 34 and the transverse plate 35 after the angle is adjusted can be fixed by means of the locking nut 32. The threaded ring 37 is fixed to the threaded tube 36. By inserting bolts into the threaded tube 36 and tightening them, the transverse plate 35 can be fixed, thereby fixing the entire monitoring structure. After the inner side of a set of transverse plates 35 is attached, an inner closed environment can be formed to achieve the purpose of storage.

[0044] Working principle: When the online monitoring structure is fixed for use, force is applied to the transverse plate 35, and the angle of the transverse plate 35 can be adjusted by rotating the thread. After the angle is adjusted, bolts can be inserted into the threaded tube 36 and tightened to fix the online monitoring structure in the designated position. When the online monitoring structure is not in use, the CCD detection sensor 13 in the mounting slot 12 can be disassembled and placed on the top of the mounting frame 11. At this time, force is applied to the transverse plate 35 again to make the inner sides of a set of transverse plates 35 fit together, and then the locking nut 32 is tightened.

[0045] This solution can meet the needs of online monitoring structure installation in various environments, as well as storage requirements, satisfying multi-functional applications, improving structural functionality, and facilitating use.
