Description

Technical Field

[0001] This utility model relates to the field of wind power electric guide rail technology, and in particular to a novel wind power electric guide rail temperature monitoring device. Background Technology

[0002] In the field of wind power conductive rails, ensuring the stable operation of the conductive rails is crucial for the efficient and safe operation of wind power generation systems. The conductive rails bear the key responsibility of transmitting electrical energy, and their operating status directly affects the power generation efficiency and reliability of the entire wind farm. Temperature monitoring of the conductive rails is an important means of ensuring their normal operation. Timely and accurate monitoring of temperature changes can effectively prevent electrical faults caused by abnormal temperatures and extend the service life of the conductive rails.

[0003] Currently, existing wind turbine conductor rail temperature monitoring devices have several technical shortcomings. The most prominent problem is the poor stability of the monitoring platform. Traditional monitoring devices often employ relatively simple and weak fixing methods, which cannot effectively cope with the complex environment in which wind turbine towers are located. Under the influence of wind vibration and mechanical deformation, the detection platform is prone to displacement. This problem directly leads to inaccurate sensor measurement references. Taking laser displacement ranging sensors and passive wireless temperature measuring devices as examples, the unstable platform makes it difficult for laser displacement ranging sensors to accurately capture conductor rail displacement data, significantly reducing measurement accuracy and failing to provide maintenance personnel with reliable conductor rail displacement status information. Simultaneously, for passive wireless temperature measuring devices, the shaking and displacement of the detection platform cannot guarantee a continuous and tight fit with the conductor rail surface, leading to deviations in temperature monitoring data and failing to reflect the true temperature changes of the conductor rail in a timely and accurate manner. Such inaccurate monitoring data may cause maintenance personnel to misjudge the operating status of the conductor rail, miss the optimal maintenance opportunity, increase the risk of conductor rail failure, and seriously affect the stable operation of the wind power system.

[0004] Therefore, there is an urgent need to develop a new type of wind power conductive rail temperature monitoring device that can effectively solve the stability problem of the monitoring platform, improve the measurement accuracy of sensors, and ensure reliable temperature and displacement monitoring. Utility Model Content

[0005] To address the aforementioned technical problems, this invention proposes a novel temperature monitoring device for wind turbine conductive rails. A unique triangular detection baffle and top rod welded structure enhances platform rigidity and reduces wind-induced vibration interference. This device effectively solves the problems of existing technologies, providing strong support for reliable temperature and displacement monitoring of wind turbine conductive rails.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a novel wind turbine conductive rail temperature monitoring device, comprising a wind turbine tower and a vertically arranged conductive rail body, with a connecting section between the wind turbine tower and the conductive rail body, the connecting section including a connecting rod connecting the side of the wind turbine tower and a parallel baffle connecting the side of the conductive rail body, and a detection mechanism suspended on the connecting section;

[0007] The detection structure is vertically attached to the side of the wind turbine tower, and laser displacement distance sensors are installed along both the vertical and horizontal directions of the detection structure.

[0008] The testing mechanism consists of, from top to bottom, a clamp assembly, a testing platform frame, a laser displacement distance sensor, and a horizontal clamp component connected to the conductive rail body rod; the horizontal clamp component is equipped with a temperature detection component for testing the conductive rail body.

[0009] Preferably, the testing platform frame includes a triangular testing baffle and a top rod vertically arranged on the top of the welded testing baffle. The top of the top rod is connected to the clamp assembly, and a horizontal clamp component is connected to the bottom side of the testing baffle.

[0010] Preferably, the clamp assembly includes an upper clamp plate and a lower clamp plate for supporting the body of the connecting rod. The upper clamp plate and the lower clamp plate are connected by a first bolt threaded between their two sides. The bottom of the lower clamp plate is fixed to the top of the top rod.

[0011] Preferably, the horizontal clamping component includes a crossbar that is laterally connected to the detection baffle and two sets of frame-shaped clamping plates that snap onto the outer side of the conductive rail body, with a second bolt threaded at the connection point of the two frame-shaped clamping plates.

[0012] Preferably, the temperature detection component includes a passive wireless temperature measurement device connected to one of the set of frame-shaped clamps.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model employs a dual-fixing design of horizontal clamping components (crossbar, frame-type clamping plate, second bolt) and clamping assembly (upper clamping plate, lower clamping plate, first bolt). Vertically, the clamping clamp provides rigid support by locking the connecting rod, while horizontally, the frame-type clamping plate clamps the conductive rail body, creating a bidirectional constraint. This ensures a stable triangular force transmission path between the detection platform frame (detection baffle, top rod), the wind turbine tower, and the conductive rail body. This design completely solves the problems of detection platform misalignment and sensor measurement inaccuracy caused by wind vibration or mechanical deformation in traditional monitoring devices. It significantly improves the displacement detection accuracy of the laser displacement ranging sensor and ensures that the passive wireless temperature measuring device continuously adheres to the conductive rail surface, achieving stable temperature data acquisition.

[0015] Secondly, the welded structure of the triangular detection baffle and the top rod enhances the rigidity of the platform through its geometric anti-deformation characteristics. Its inclined design can guide the airflow on the side of the tower, reduce wind vibration interference, and further ensure the measurement stability of the laser displacement ranging sensor under complex wind conditions.

[0016] Thirdly: The split clamp assembly enables quick assembly and disassembly of the connecting rod through the cooperation of the upper and lower clamp plates and the first bolt, improving installation efficiency; the symmetrical clamping structure of the frame-type clamping plate and the second bolt is compatible with conductive rails of different sizes, avoiding surface damage to the conductive rails caused by single-point stress and enhancing the versatility of the device.

[0017] Fourthly, the passive wireless temperature measurement device is directly integrated into the frame clamp, using clamping force to tightly adhere to the surface of the conductive rail, achieving rapid temperature monitoring response. Furthermore, its use of ultra-low starting current CT power supply technology and ISM band LoRa wireless transmission eliminates the need for wiring, removing the risk of signal interference in strong electromagnetic environments. It also enables long-term, maintenance-free, and reliable operation in unattended substations, meeting the demands of modern wind farms for intelligent and minimally staffed operation and maintenance, significantly reducing maintenance costs and safety risks.

[0018] This invention solves the problems of inaccurate detection data, high maintenance costs, and significant safety hazards in existing wind power rail monitoring devices due to poor platform stability, complex sensor installation, and low environmental adaptability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides a novel wind turbine conductive rail temperature monitoring device through improvements. The technical solution of this utility model is as follows:

[0028] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0029] like Figure 1 - Figure 4 As shown, a novel wind turbine conductive rail temperature monitoring device includes a wind turbine tower 1 and a vertically arranged conductive rail body 2. A connecting section connects the wind turbine tower 1 and the conductive rail body 2. The connecting section includes a connecting rod 3 connecting the side of the wind turbine tower 1 and a parallel baffle 301 connecting the side of the conductive rail body 2. A detection mechanism is suspended on the connecting section. The detection structure is vertically attached to the side of the wind turbine tower 1. The detection structure is equipped with laser displacement ranging sensors 7 in both the vertical and horizontal directions. The detection mechanism consists of, from top to bottom, a clamp assembly, a detection platform frame, laser displacement ranging sensors 7, and a horizontal clamp component connecting the rod of the conductive rail body 2. A temperature detection component for detecting the conductive rail body 2 is provided on the horizontal clamp component.

[0030] like Figure 2 As shown, in one embodiment, the detection platform frame includes a triangular detection baffle 401 and a top rod 4 vertically arranged on the top of the welded detection baffle 401. The top of the top rod 4 is connected to the clamp assembly, and a horizontal clamp component is connected to the bottom side of the detection baffle 401. The connection between the clamp assembly and the detection baffle 401 via the top rod 4, and the connection of the horizontal clamp component to the bottom side of the detection baffle 401, enables the stable construction of the detection platform frame, providing a stable installation foundation for the laser displacement ranging sensor 7 and the temperature detection assembly, facilitating the detection of displacement and temperature of the conductive rail body 2.

[0031] like Figure 1 - Figure 3 As shown, in one embodiment, the clamp assembly includes an upper clamp plate 5 and a lower clamp plate 501 for supporting the connecting rod 3. A first bolt 502 is threaded between the two sides of the upper clamp plate 5 and the lower clamp plate 501. The bottom of the lower clamp plate 501 is fixed to the top of the top rod 4. By cooperating with the upper clamp plate 5, the lower clamp plate 501, and the first bolt 502 to support the connecting rod 3, and with the bottom of the lower clamp plate 501 fixed to the top rod 4, the testing platform frame is securely installed on the wind turbine tower 1, ensuring the stability of the connection between the testing platform frame and the wind turbine tower 1, and preventing the testing platform frame from shaking or falling off during operation.

[0032] like Figure 2 As shown, in one embodiment, the horizontal clamp component includes a horizontal bar 6 connected laterally to the detection baffle 401 and two sets of frame-shaped clamps 601 that clamp onto the outer side of the conductive rail body 2. The two ends of the frame-shaped clamps 601 are threaded with second bolts 602. By providing a horizontal clamp component between the conductive rail body 2 and the detection platform frame, i.e., the horizontal bar 6 connects to the detection baffle 401, and the frame-shaped clamps 601 clamp onto the conductive rail body 2 and are fixed by the second bolts 602, two sets of horizontal and vertical support structures are formed with the clamp assembly at the top of the detection platform frame. This ensures the stability of the detection platform frame in contact with the side of the wind turbine tower 1, preventing deviation and shaking, which could lead to inaccurate detection by the laser displacement ranging sensor 7. This improves the accuracy of displacement detection of the conductive rail body 2 and enables the temperature detection component to stably detect the temperature of the conductive rail body 2.

[0033] In one embodiment, the detection structure is equipped with laser displacement ranging sensors 7 along both the vertical and horizontal directions. By installing laser displacement ranging sensors 7 in both the vertical and horizontal directions, the displacement of the conductive rail body 2 can be detected from all directions, improving the accuracy and comprehensiveness of displacement monitoring and enabling timely detection of any potential displacement anomalies. In another embodiment, the temperature detection component includes a passive wireless temperature measuring device 8 connected to one of the frame-type clamps 601. Connecting the passive wireless temperature measuring device 8 to the frame-type clamps 601 enables real-time temperature detection of the conductive rail body 2. The passive wireless method avoids cumbersome wiring, reduces safety hazards, and facilitates installation and maintenance. The passive wireless temperature measuring device 8, officially named BFtontruO3-NTC-CT, is a passive wireless temperature measuring device independently developed by our company. It adopts CT power extraction technology, achieving truly passive power supply and shortening the temperature measurement cycle. This device can operate reliably without maintenance for a long time, fully meeting the requirements of unmanned substations. The main part is to address abnormal temperature and displacement conditions that occur in the conductive rail during the operation of the wind turbine.

[0034] Product technical features:

[0035] This product offers a temperature measurement accuracy of up to ±1℃ for wind turbine towers. It is an ISM band LoRa wireless temperature measurement product with ultra-low starting current CT power supply and long-distance transmission.

[0036] The passive wireless temperature measurement device 8 is mainly installed on the conductive rail body 2. It wirelessly uploads the temperature measurement data to a USB wireless signal receiver, which then transmits the data to an industrial control computer via a USB interface. The industrial control computer then uploads the temperature measurement data to the booster station via the 4G Cat network on the top pole, thus forming a distributed monitoring system.

[0037] The laser displacement ranging sensor 7 is mainly installed on the conductive rail housing. It wirelessly uploads displacement data to a USB wireless signal receiver, which then transmits the data to an industrial control computer via a USB interface. The industrial control computer then uploads the displacement data to the substation via the 4G Cat network on the wind turbine tower 1, thus forming a distributed monitoring system.

[0038] The working principle and usage process of this utility model are as follows: First, the clamp assembly is fixed to the connecting rod 3 using the upper clamp plate 5, the lower clamp plate 501, and the first bolt 502, thereby installing the testing platform frame on the wind turbine tower 1. Next, a horizontal clamping component consisting of a crossbar 6, a frame-type clamping plate 601, and a second bolt 602 connects the conductive rail body 2 to the testing platform frame, ensuring the stability of the testing platform frame. Then, vertical and horizontal laser displacement ranging sensors 7 monitor the displacement of the conductive rail body 2 in real time, and a passive wireless temperature measuring device 8 connected to the frame-type clamping plate 601 monitors the temperature of the conductive rail body 2 in real time. When the conductive rail body 2 experiences displacement or temperature abnormalities, it can be detected and addressed promptly.
