Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a matching installation structure for a wind turbine blade icing sensor. Background Technology

[0002] In the field of wind power generation, snow and ice disasters during the autumn-winter transition each year often test human engineering. When water freezes, it expands in volume, which can bring dangers to production and life. For example, power transmission lines may be broken by ice, traffic accidents may occur due to icy roads, and tower structures may collapse due to ice. According to incomplete statistics, the direct economic losses caused by snow and ice disasters in my country reach tens of billions of yuan every year. Icing sensors can monitor and warn in real time. However, icing on wind turbine blades can worsen aerodynamic performance, reduce power generation efficiency, and even cause safety hazards. Therefore, it is necessary to securely install icing sensors on wind turbine blades. As a result, a matching installation structure for wind turbine blade icing sensors has emerged to ensure the safe operation of wind power equipment.

[0003] During wind turbine blade operation, the icing sensor installation structure ensures monitoring through the collaborative efforts of multiple components. The bracket uses an aluminum alloy triangular structure with sealant to enhance connection strength and isolate moisture, fixing the sensor in airflow and vibration. The cable sealing channel has a built-in Kevlar braided layer and metal corrugated pipe, with waterproof rubber rings to protect the cable. The signal conditioning box amplifies the weak sensor signal and filters out electromagnetic interference to ensure data transmission. The protective cover and airflow guiding structure block wind and snow and guide airflow to reduce icing. The heating film and temperature compensation module adjust the temperature and correct errors. The detachable calibration interface and maintenance platform facilitate sensor calibration, ice removal, and component replacement, ensuring equipment operation.

[0004] Currently, the installation structure of wind turbine blade icing sensors has a positive effect on the industry. However, the traditional triangular bracket structure lacks stability in complex environments. In low-temperature cold waves, the bracket material is prone to stress fatigue due to thermal expansion and contraction. Icing loads can disrupt the mechanical balance of the triangular structure, causing the sensor measurement position to shift. High-altitude airflow can cause the bracket to resonate, leading to aging and cracking of the sealant. Moisture penetration can exacerbate metal corrosion, causing the installation structure to loosen, and even causing the blade to aerodynamically unbalance due to structural detachment. Therefore, a new installation structure for wind turbine blade icing sensors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a matching installation structure for a wind turbine blade icing sensor, aiming to improve the problem of insufficient stability of the traditional triangular support structure in complex environments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mounting structure for a wind turbine blade icing sensor includes a blade body. Two fixing blocks are fixedly connected to the top of the blade body. A stud is threaded onto the inner wall of each fixing block. A rotating disk is fixedly connected to one side of each stud. Limit blocks are slidably connected to the outer wall of each fixing block. A housing is fixedly connected to the adjacent side of the two limit blocks. A sealing ring is fixedly connected to the inner wall of the housing. A top cover is fixedly connected to the top of the sealing ring. Two electrodes are fixedly connected to the inner wall of the top cover. A temperature and humidity port is fixedly connected to the inner wall of the housing. An aviation insertion tube is fixedly connected to the inner wall of the housing. A fixing plate is fixedly connected to the bottom of the housing. A reinforcing component is threaded onto the inner wall of the fixing plate.

[0008] As a further description of the above technical solution:

[0009] The reinforcement assembly includes two screws, the outer walls of which are threaded to the inner wall of the fixing plate. Two washers are provided on the top of the fixing plate, two spring washers are fixedly connected to the bottom of the fixing plate, and two elastic blocks are fixedly connected to the bottom of the fixing plate.

[0010] As a further description of the above technical solution:

[0011] The inner walls of the two elastic blocks are respectively fixedly connected to the outer walls of the two fixed blocks, and the bottom of the elastic blocks is in contact with the top of the blade body;

[0012] As a further description of the above technical solution:

[0013] The inner wall of the limiting block is provided with a screw hole, and the outer wall of the stud is threaded to the inner wall of the screw hole;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the upper cover is fixedly connected to the inner wall of the housing, and one side of the rotating disk is in contact with one side of the limiting block;

[0016] As a further description of the above technical solution:

[0017] The top of the washer contacts the outer wall of the screw, and the bottom of the spring washer contacts the top of the blade body;

[0018] As a further description of the above technical solution:

[0019] The gasket has a T-shaped cross-section, the rotating disk has a hexagonal shape, and a titanium electrode plate is fixedly connected to the inner wall of the upper cover.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the spring pad is in contact with the outer wall of the gasket, and the bottom of the limiting block is fixedly connected to the top of the fixed plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by aligning the limiting block with the fixing block and pressing the housing towards the blade body, the elastic block and the bottom of the spring pad are made to fit against the blade. When the limiting block reaches the predetermined position of the fixing block, the stud is aligned with the screw hole and the rotating disk is rotated. The rotating disk drives the stud to rotate, so that the limiting block and the fixing block are locked together and tightened. The wedge structure of the two forms a self-locking mechanism. At this time, the elastic block is deformed by pressure, and the reaction force presses the fixing disk against the blade. The spring pad fills the slight unevenness of the mounting surface, so that the fixing disk is initially fixed under the action of mechanical locking and elastic clamping, ensuring that the mounting structure fits tightly against the blade.

[0024] 2. In this utility model, rotating the screw fixes the fixed plate and the blade body for a second time, making the housing more secure. The shim fills the gap between the screw and the fixed plate, increasing friction and reducing the probability of thread stripping. The elastic material of the spring washer and the elastic block can absorb external forces through deformation, reducing the impact transmitted from the fixed plate to the housing, so that the housing can effectively protect the internal components and avoid external damage, thereby greatly extending the service life of the icing sensor.

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a wind turbine blade icing sensor mounting structure, including a blade body 1. The blade body 1 is a key component of the wind turbine equipment, providing a mounting carrier for the icing sensor. Two fixing blocks 3 are fixedly connected to the top of the blade body 1. The fixing blocks 3 serve as basic connecting components, providing mounting positions for subsequent components and ensuring the stability of the mounting structure. A stud 16 is threadedly connected to the inner wall of the fixing block 3. A rotating disk 4 is fixedly connected to one side of the stud 16. The rotating disk 4 facilitates the operator to apply force to rotate the stud 16, making the installation operation more convenient and efficient. A limit block 5 is slidably connected to the outer wall of the fixing block 3. The limit block 5 can slide along the fixed block during installation. The fixed block 3 slides to facilitate position adjustment for precise installation. The housing 6 is fixedly connected to the side of the two limit blocks 5 that are close to each other. The housing 6 is used to house the internal components of the icing sensor and provide them with protective space. The inner wall of the housing 6 is fixedly connected to a sealing ring 12. The sealing ring 12 can effectively prevent external moisture, dust and other substances from entering the interior of the housing 6, ensuring the normal working environment of the internal components. The top of the sealing ring 12 is fixedly connected to a top cover 9. The top cover 9 cooperates with the housing 6 to further enhance the sealing effect. The inner wall of the top cover 9 is fixedly connected to two electrodes 11. The electrodes 11 are the key detection components of the icing sensor, used to detect the icing state of the blade surface and transmit signals.

[0033] A temperature and humidity port 8 is fixedly connected to the inner wall of the housing 6. This port can monitor the temperature and humidity data of the blade surface in real time, aiding in the assessment of icing conditions. An aviation connector 7 is also fixedly connected to the inner wall of the housing 6. This connector enables electrical connection between the sensor and external equipment, ensuring stable signal transmission. A mounting plate 18 is fixedly connected to the bottom of the housing 6. This plate securely connects the housing 6 to the blade body 1, enhancing the stability of the overall installation structure. A reinforcing component is threaded onto the inner wall of the mounting plate 18. This component further strengthens the connection between the mounting plate 18 and the blade body 1. The reinforcing component includes two screws 1. 3. The outer walls of the two screws 13 are threaded to the inner wall of the fixing plate 18. The two screws 13 achieve secondary fixation between the fixing plate 18 and the blade body 1 through the threaded connection, ensuring that the installation structure is firm and reliable. Two washers 14 are provided on the top of the fixing plate 18. The washers 14 are used to assist the screws 13 in fixing and improve the fixing effect. Two spring washers 15 are fixedly connected to the bottom of the fixing plate 18. The spring washers 15 can absorb external forces and protect the installation structure and internal components. Two elastic blocks 2 are fixedly connected to the bottom of the fixing plate 18. The elastic blocks 2 also play a buffering role and reduce the impact of external vibration on the sensor.

[0034] Reference Figures 2 to 4 The inner walls of the two elastic blocks 2 are fixedly connected to the outer walls of the two fixed blocks 3, so that the elastic blocks 2 and the fixed blocks 3 are tightly combined to effectively transmit the buffering effect. The bottom of the elastic block 2 is in contact with the top of the blade body 1 to ensure that the elastic block 2 can directly absorb the vibration and force from the blade body 1. The inner wall of the limiting block 5 is provided with a screw hole 17, which is matched with the stud 16 to realize the threaded connection between the limiting block 5 and the fixed block 3. The outer wall of the stud 16 is threaded to the inner wall of the screw hole 17 to ensure the tightness and stability of the connection. The outer wall of the top cover 9 is fixedly connected to the inner wall of the housing 6, so that the top cover 9 and the housing 6 form a sealed whole to protect the internal components. One side of the rotating disk 4 is in contact with one side of the limiting block 5 to ensure that the stud 16 can be effectively driven to rotate when the rotating disk 4 is rotated. The top of the washer 14 is in contact with the outer wall of the screw 13. To enhance the stability of screw 13 during fixing and prevent stripping, the bottom of spring pad 15 contacts the top of blade body 1, allowing spring pad 15 to directly buffer vibrations from blade body 1. The cross-sectional shape of pad 14 is T-shaped, which better matches the fixing plate 18 and screw 13, improving the fixing effect. The rotating plate 4 is hexagonal, making it easy to use tools such as wrenches to apply force for rotation, improving installation efficiency. The inner wall of the top cover 9 is fixedly connected to titanium electrode plate 10, which can enhance the detection performance and stability of the sensor. The inner wall of spring pad 15 contacts the outer wall of pad 14, allowing spring pad 15 and pad 14 to cooperate with each other to improve the fixing effect and buffering performance. The bottom of limit block 5 is fixedly connected to the top of fixing plate 18, making limit block 5 and fixing plate 18 integrated, enhancing the stability of the overall structure.

[0035] Working principle: When an icing sensor needs to be installed on the surface of a wind turbine blade, the limiting block 5 is aligned with the fixing block 3 and pressed against the housing 6 towards the blade body 1, so that the bottom of the elastic block 2 and the elastic pad 15 contacts the blade body 1. When the limiting block 5 reaches the predetermined position of the fixing block 3, the stud 16 is aligned with the screw hole 17 and the rotating disk 4 is rotated, so that the rotating disk 4 drives the stud 16 to rotate, thereby firmly fixing the limiting block 5 and the fixing block 3, initially fixing the fixing disk 18, and initially achieving the fixing effect of the housing 6. At this time, the screw 13 is rotated. This allows the screw 13 to fix the fixed plate 18 and the blade body 1 a second time, making the housing 6 more secure. Thanks to the presence of the washer 14, the probability of the screw 13 stripping due to external influences during thread fixing is greatly reduced. Thanks to the presence of the spring washer 15 and the elastic block 2, the elastic material allows the spring washer 15 and the elastic block 2 to absorb some of the external force, which greatly reduces the external force transmitted from the fixed plate 18 to the housing 6. This allows the housing 6 to protect the internal components well, thus greatly extending the service life of the entire icing sensor.
