Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a wind turbine blade icing monitoring device. Background Technology

[0002] Wind turbine blades are the core aerodynamic components of wind turbines, typically made of composite materials. Mounted on the hub, they capture wind energy through rotation, converting kinetic energy into mechanical energy, which is then used to drive the generator. The blade design directly impacts the wind turbine's wind capture efficiency and power generation capacity. The core function of wind turbine blade icing monitoring devices is to ensure the safe and stable operation of the turbine, improve power generation efficiency, and reduce maintenance costs. Blade icing alters its aerodynamic shape, increases air resistance and its own load, significantly reducing wind capture efficiency and power generation, and can also cause tower damage due to ice shedding.

[0003] First, clean and polish the designated monitoring area of ​​the wind turbine to remove oil, dust and oxide layer to ensure proper installation. Then, depending on the type of device, use adhesive to fix the icing monitor in the preset position.

[0004] In existing technologies, some wind turbine blade icing monitoring devices require the use of glue to install the icing monitor during installation. This makes cleaning difficult during subsequent replacement or maintenance, and can damage the icing monitor, resulting in complex, time-consuming, and labor-intensive replacement. Therefore, a wind turbine blade icing monitoring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wind turbine blade icing monitoring device, which aims to improve the problem of inconvenient replacement of some existing icing monitoring instruments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wind turbine blade icing monitoring device includes a wind turbine and a mounting frame. An icing monitor is fixedly connected to the top side of the mounting frame. A reset assembly is slidably connected inside the mounting frame. Two pressing plates are fixedly connected to the top side of the reset assembly. Limit blocks are fixedly connected to both the front and rear sides of the mounting frame. Two limit frames are fixedly connected to the top side of the wind turbine. As a further description of the above technical solution: The outer side of the icing monitor is fixedly connected to multiple mounting plates. The internal threads of the mounting plates are connected to screws, and the external threads of the screws are connected to fixing plates. A cover plate is fixedly connected to one side of the multiple fixing plates, and a sealing plate is fixedly connected to the rear side of the cover plate. Multiple arc-shaped columns are fixedly connected to the front side of the icing monitor. Preferably, the reset assembly includes two sliding plates, the outer surfaces of the two sliding plates are slidably connected to the inside of the mounting bracket, and springs are fixedly connected to the adjacent sides of the two sliding plates; Preferably, the two pressing plates are externally slidably connected to the inside of the mounting bracket, and the top side of the sliding plate is fixedly connected to the bottom side of the pressing plate; Preferably, the outer side of the sliding plate is slidably connected to the inside of the limiting block, and the outer side of the sliding plate is slidably connected to the inside of the limiting frame; Preferably, the sealing plate has multiple arc-shaped openings on its rear side, and the outer part of the arc-shaped column is engaged with the inside of the arc-shaped openings; Preferably, the rear side of the fixing plate contacts the front side of the mounting plate, and the rear side of the sealing plate contacts the front side of the icing monitor.

[0007] This utility model has the following beneficial effects: 1. In this utility model, when the pressing plate is released, the spring will rebound and reset, pushing the sliding plate to move in the opposite direction, so that it is locked with the limit frame again, ensuring that the mounting bracket is firmly fixed on the unit, thereby facilitating its installation.

[0008] 2. In this utility model, multiple arc-shaped columns are set on the icing monitor. When the sealing plate is in place, the arc-shaped columns will be inserted into the arc-shaped opening.

[0011] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. Reference Figures 1 to 3 The system includes a wind turbine 1 and a mounting bracket 2. An icing monitor 3, model FH-9007-II, is fixedly connected to the top side of the mounting bracket 2. The icing monitor 3 integrates sensors or an optical system to detect the icing condition on the surface of the wind turbine blades 1 in real time. The icing monitor 3 is fixed in a favorable observation position via the mounting bracket 2 and transmits monitoring data back to the control system, providing a basis for de-icing decisions. A reset assembly is slidably connected inside the mounting bracket 2. The reset assembly includes two sliding plates 5, one end of which is connected to a... The pressure plate 6 is connected to receive the operating force, and the other end is used to engage or disengage with the limiting frame 8 on the wind turbine 1. The two sliding plates 5 are externally slidably connected to the inside of the mounting frame 2. A spring 4 is fixedly connected to the adjacent side of the two sliding plates 5. The spring 4 is an elastic element of the reset assembly and is connected between the two sliding plates 5. The main function of the spring 4 is to provide a constant restoring force. When the operator releases the pressure plate 6, the elastic force of the spring 4 will automatically push the two sliding plates 5 to reset inward or outward, so that they re-engage with the limiting frame 8 and achieve automatic locking. Two pressing plates 6 are fixedly connected to the top side of the reset assembly. When the mounting bracket 2 needs to be installed or removed, the operator can directly drive the sliding plate 5 to move against the elastic force of the spring 4 by pressing or pulling the two pressing plates 6, thereby releasing or establishing the locking state. The two pressing plates 6 are externally slidably connected to the inside of the mounting bracket 2, and the top side of the sliding plate 5 is fixedly connected to the bottom side of the pressing plates 6. Limiting blocks 7 are fixedly connected to both the front and rear sides of the mounting bracket 2. The limiting blocks 7 are fixed inside the mounting bracket 2, providing precise movement guides and boundary restrictions for the sliding plate 5, ensuring that the sliding plate 5 can only move along the... The preset straight path moves inside the mounting frame 2 to prevent it from deflecting or getting stuck during sliding, ensuring the reliability and stability of the locking mechanism. The external sliding connection of the sliding plate 5 is connected to the inside of the limiting block 7. Two limiting frames 8 are fixedly connected to the top side of the wind turbine 1. The limiting frame 8 is a locking interface fixed on the main body of the wind turbine 1. Its internal structure is designed to match the end of the sliding plate 5. When the mounting frame 2 is placed in place, the sliding plate 5 will be inserted into the inside of the limiting frame 8 under the action of the spring 4, thereby firmly locking the entire mounting frame 2 onto the wind turbine 1.

[0012] Reference Figures 3 to 5 The sliding plate 5 is externally slidably connected to the inside of the limiting frame 8. Multiple mounting plates 9 are fixedly connected to the outside of the icing monitor 3. The mounting plates 9 are pre-set connection structures on the body of the icing monitor 3, providing standardized threaded holes. The function of the mounting plates 9 is to connect to the external fixing plate 11 via screws 10, thereby fastening the protective structures such as the cover plate 12 and sealing plate 13 to the front side of the icing monitor 3, forming a complete outer shell. The mounting plates 9 have internal threads connected to screws 10. Tightening the screws 10 generates a strong axial tensile force, firmly pressing the fixing plate 11, cover plate 12, and sealing plate 13 against the body of the icing monitor 3, ensuring reliable sealing. The screws 10 have external threads connected to the fixing plate 11. The fixing plate 11 is a rigid component that transmits and distributes the tightening force. The head of the screw 10 acts on the fixing plate 11, and the fixing plate 11 then tightens the screw... The tightening force of screw 10 is evenly transmitted to cover plate 12. This design avoids the screw head directly acting on cover plate 12, prevents stress concentration, and ensures that the entire sealing structure is evenly stressed and tightly fitted. The rear side of fixing plate 11 contacts the front side of mounting plate 9. Cover plate 12 is fixedly connected to the adjacent side of multiple fixing plates 11. Cover plate 12 constitutes the main body of the front protective structure of icing monitor 3, providing rigid support and external protection for the internal sealing plate 13. Cover plate 12 is fastened by fixing plate 11 and screw 10. Sealing plate 13 is fixedly connected to the rear side of cover plate 12. Sealing plate 13 is the component that realizes waterproof and dustproof front of icing monitor 3. It is usually made of elastic material and is pressed by cover plate 12 to the front side of the body of icing monitor 3. Sealing plate 13 fills the tiny gaps of the connection interface through its own elastic deformation, effectively preventing moisture, rain and dust from entering the instrument.

[0013] Reference Figures 4 to 6 The rear side of the sealing plate 13 contacts the front side of the icing monitor 3. Multiple arc-shaped openings 14 are provided on the rear side of the sealing plate 13. These arc-shaped openings 14 are precision positioning structures on the sealing plate 13, and their shape and position correspond to the arc-shaped posts 15 on the icing monitor 3. The main function of the arc-shaped openings 14 is to guide the sealing plate 13 into accurate position during installation and engage with the arc-shaped posts 15, preventing the sealing plate 13 from rotating or misaligning during tightening. The outer side of the arc-shaped posts 15 engages with the inner side of the arc-shaped openings 14. Multiple arc-shaped posts 15 are fixedly connected to the front side of the icing monitor 3. These arc-shaped posts 15 are positioning components fixed to the body of the icing monitor 3 and cooperate with the arc-shaped openings 14 on the sealing plate 13. When the sealing plate 13 is tightened, the arc-shaped posts 15 precisely engage with the arc-shaped openings 14. This male-female mating structure greatly enhances the stability and accuracy of the seal, ensuring that the sealing plate 13 is in the correct position under the tightening force of the screws 10.

[0014] When installing or adjusting this device, the two pressing plates 6 need to be pulled outward first. This action will cause the two sliding plates 5 at the bottom to slide outward. The sliding plates 5 move inside the mounting frame 2 and under the guidance of the limiting block 7 and the limiting frame 8. The purpose of this process is to separate or engage the sliding plates 5 with the limiting frame 8 on the top of the wind turbine 1, so as to realize the convenient installation or removal of the entire mounting frame 2 together with the icing monitor 3 on the top of it on the wind turbine 1. When the pressing plates 6 are released, the spring 4 will rebound and reset, pushing the sliding plates 5 to move in the opposite direction, so that they are locked with the limiting frame 8 again, ensuring that the mounting frame 2 is firmly fixed on the unit.

[0015] Once the mounting bracket 2 is fixed, the FH-9007-II model icing monitor 3 on its top side begins to work, monitoring the blades of the wind turbine 1. The sealing function is mainly used to protect the icing monitor 3. During assembly, multiple screws 10 are operated to screw them into the mounting plate 9 on the outside of the icing monitor 3. As the screws 10 are tightened, they will drive the fixing plate 11, as well as the cover plate 12 and sealing plate 13 connected to the fixing plate 11. As the screws 10 are continuously tightened, the fixing plate 11 will gradually approach and eventually contact the mounting plate 9. At the same time, the sealing plate 13 will also be strongly pulled towards the front of the icing monitor 3 until the two are tightly fitted together. To ensure the accuracy and firmness of the seal, the sealing plate 13 has multiple arc-shaped openings 14, while the icing monitor 3 has multiple arc-shaped posts 15. When the sealing plate 13 is in place, the arc-shaped posts 15 will be inserted into the arc-shaped openings 14. By fastening with the screws 10, moisture, dust and other substances are prevented from entering at the connection of the icing monitor 3.
