Description

Technical Field

[0001] This utility model relates to the technical field of small wind turbine brake disc loss detection device, specifically a small wind turbine brake disc loss detection device. Background Technology

[0002] With the increasing global demand for clean energy, small wind power generation, as a distributed and flexible renewable energy utilization method, has been widely used in power supply in remote areas, energy supply for small communities, and power consumption in special scenarios. However, the operation and maintenance of small wind turbines face many challenges. From an installation location perspective, small wind turbines are often deployed in remote areas, making it costly and difficult for professional maintenance personnel to travel there for inspections; furthermore, their installation areas are relatively dispersed, making centralized and large-scale efficient maintenance difficult. The brake disc, as a key component of a small wind turbine, plays a crucial role in the turbine's braking process. Due to frequent braking and long-term use, brake discs inevitably wear down. If excessive wear is not detected and replaced in time, it may lead to wind turbine brake failure, causing safety accidents, and also affecting the normal operation and power generation efficiency of the turbine. Currently, traditional methods for detecting brake disc wear in small wind turbines often require disassembling the turbine, which is not only time-consuming and labor-intensive but may also cause additional damage to the equipment due to improper disassembly. Therefore, there is an urgent need for a device that can conveniently, quickly, and accurately detect brake disc wear without disassembling the equipment. Laser ranging technology, with its advantages of high precision and non-contact measurement, provides an effective solution to this problem. This detection method eliminates the need for frequent on-site inspections and equipment disassembly, greatly improving the convenience and reliability of daily maintenance of small wind turbines. This is of great significance for ensuring the stable operation of small wind turbines and extending their service life. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small wind turbine brake disc loss detection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a small wind turbine brake disc loss detection device, comprising a brake disc loss detection device, the brake disc loss detection device comprising a laser emitting component, a support frame disposed below the laser emitting component, a base fixedly disposed below the support frame, and fixed brackets symmetrically disposed on both sides of the base.

[0005] As a further description of the above technical solution:

[0006] The brake disc wear detection device is provided in two sets and is symmetrically fixed on both sides of the brake disc.

[0007] As a further description of the above technical solution:

[0008] The base is secured by bolts evenly distributed at the four corners above.

[0009] As a further description of the above technical solution:

[0010] Each of the fixed brackets has bolts at the end furthest from the support frame for support and reinforcement.

[0011] This utility model has the following beneficial effects:

[0012] 1. By symmetrically setting up loss detection devices on both sides of the brake disc, non-contact measurement is achieved using laser emission components to accurately capture the thickness changes of the brake disc caused by wear and provide real-time data feedback, thereby avoiding safety accidents caused by excessive wear of the brake disc and ensuring the stable operation of small wind turbines.

[0013] 2. Brake disc wear can be self-tested without disassembling the wind turbine, significantly reducing the frequency of on-site maintenance for users, reducing manpower, material and time costs, and is easy to use and test, improving daily maintenance efficiency. Attached Figure Description

[0018] 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.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1:

[0022] like Figures 1 to 2 As shown in the figure, this embodiment provides a small wind turbine brake disc wear detection device, including a brake disc wear detection device 7. The brake disc wear detection device 7 includes a laser emitting component 1, which integrates a high-precision laser emitter and a signal receiver. It can quickly emit a laser beam and receive the reflected signal. It also has a built-in high-precision timing module to accurately record the time interval between laser emission and reception. Based on the laser ranging principle, it can quickly calculate the distance to the brake disc surface. A support frame 2 is provided below the laser emitting component 1. The support frame 2 is made of high-strength lightweight alloy material and has a shock-absorbing structure inside, which can effectively absorb the vibration generated by the wind turbine during operation and avoid the vibration affecting the measurement accuracy of the laser emitting component 1. The support frame 2 and the laser emitting component 1 are fixed by a detachable threaded connection, which facilitates the later maintenance and replacement of the laser emitting component 1. A base 3 is fixedly provided below the support frame 2. The surface of the base 3 is provided with a horizontal adjustment device, including multiple adjustable support feet, which can perform horizontal calibration of the detection device on uneven mounting surfaces to ensure that the laser emitting component 1 is perpendicular to the surface of the brake disc 6, thereby ensuring the accuracy of the measurement. The base 3 has fixed supports 4 symmetrically arranged on both sides.

[0023] Two sets of brake disc wear detection devices 7 are installed and symmetrically fixed on both sides of the brake disc 6. The two sets of detection devices are connected to the central processing module via data cables. The central processing module can synchronously receive the distance data measured by the two sets of detection devices, and accurately determine the wear thickness of the brake disc 6 by calculating the sum of the distance changes on both sides. At the same time, the central processing module is also equipped with a data storage and wireless transmission unit, which can store the measurement data in real time and transmit the data to the remote monitoring center via a wireless network, so that staff can remotely monitor the brake disc wear status.

[0024] Example 2:

[0025] The base 3 is secured by bolts 5 evenly distributed at the four corners. The bolts 5 are designed to prevent loosening; the threaded portion is coated with high-strength anti-loosening adhesive, and a spring washer is placed under the nut. This effectively prevents the bolts 5 from loosening under the vibration environment of the wind turbine during operation, ensuring the stable installation of the testing device. In addition, the bolt holes on the base 3 are countersunk, so that the head of the bolt 5 is embedded in the base 3, avoiding the protruding bolts 5 from interfering with or damaging other components of the wind turbine.

[0026] Bolts 5 are provided at the ends of the fixed brackets 4 away from the support frame 2 for support and reinforcement. The fixed brackets 4 have a triangular support structure, forming a stable triangular force system with the base 3 and the mounting surface, further enhancing the stability of the testing device. By using the bolts 5 to cooperate with the mounting holes at different positions, it can adapt to the installation environment of wind turbines of different specifications, realizing flexible installation and fixation of the testing device.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
