Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wind turbines, and specifically refers to an automatic monitoring device for the offset and edge wear of a toothed belt. Background Art
[0002] The toothed belt drive pitch structure is an important pitch technology for large wind turbines. When the wind turbine starts, stops, or adjusts power, the blades move back and forth within the range of 0 to 92 degrees. During this process, the toothed belt plays a role in torque transmission and balanced steering. Due to the complex working environment of the wind turbine and frequent pitch movements, the toothed belt is prone to offset, edge wear, and broken strands during operation. If not adjusted and processed in time, the toothed belt drive pitch structure will be damaged.
[0003] There is no dedicated automatic monitoring device for the offset and edge wear and broken strands of the toothed belt in the current toothed belt drive pitch structure. Summary of the Utility Model
[0004] To solve the above problems, the utility model provides an automatic monitoring device for the offset and edge wear of a toothed belt, which is used for the early protection of the toothed belt in the toothed belt drive pitch structure.
[0005] To achieve the above functions, the technical solution adopted by the utility model is as follows: an automatic monitoring device for the offset and edge wear of a toothed belt, including a fixed bracket, on which a control box is installed. On the left side of the fixed bracket, an infrared transmitter I and an infrared transmitter II are installed. On the right side of the fixed bracket, an infrared receiver I and an infrared receiver II are installed. Resistive pressure sensors are installed on the left and right side walls of the fixed bracket. A micro high-decibel alarm is installed on the fixed bracket and is located on the side of the control box.
[0006] As a preferred technical solution of the utility model, the infrared transmitter I, the infrared transmitter II, the infrared receiver I, the infrared receiver II, the resistive pressure sensor, and the micro high-decibel alarm are all connected to the control box through wires.
[0007] Compared with the prior art, the beneficial effects achieved by the present utility model with the above structure are as follows: The structure is firm, with strong corrosion resistance, convenient installation, light weight, and can be fixed by using the bolts connecting the blade and the hub of the wind turbine generator; it can be applied to all MW-level toothed belt drive variable pitch structure wind turbine generators, and the cost of one automatic monitoring device is low and can be directly promoted and used; it can reduce the damage of the entire toothed belt drive variable pitch structure caused by the offset and edge wear and broken strands of the toothed belt, improving the reliability of the equipment; at the same time, it reduces the downtime of the wind turbine due to faults, thereby increasing the power generation. As the operating years of the wind turbine increase, the use value will be further improved. Description of the Drawings

[0011] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0012] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The following will further describe the present utility model in detail in conjunction with the drawings.
[0013] Such as Figure 1-2As shown in the figure, an automatic monitoring device for the offset and edge wear of a toothed belt provided by the present utility model includes a fixed bracket 1, on which a control box 8 is installed. On the left side of the fixed bracket 1, an infrared transmitter 1 2 and an infrared transmitter 2 3 are installed. On the right side of the fixed bracket 1, an infrared receiver 1 4 and an infrared receiver 2 5 are installed. Resistive pressure sensors 6 are installed on both the left and right side walls of the fixed bracket 1. Whether the toothed belt has edge wear and broken strands during operation is monitored through the infrared transmitter 1 2 and the infrared receiver 1 4, the infrared transmitter 2 3 and the infrared receiver 2 5, and the resistive pressure sensor 6. A micro high-decibel alarm 7 is installed on the fixed bracket 1 and is located on the side of the control box 8. The infrared transmitter 1 2, the infrared transmitter 2 3, the infrared receiver 1 4, the infrared receiver 2 5, the resistive pressure sensor 6, and the micro high-decibel alarm 7 are all connected to the control box 8 through wires.
[0014] During specific use, whether the toothed belt has edge wear and broken strands during operation is monitored through the infrared transmitter 1 2 and the infrared receiver 1 4, the infrared transmitter 2 3 and the infrared receiver 2 5, and the resistive pressure sensor 6. If the above situation occurs, when the wind turbine generator is shut down during daily inspection, the infrared interruption or the conduction of the pressure sensor will be triggered, causing the micro high-decibel alarm 7 to alarm.
[0015] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
