Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine monitoring, in particular to a barometer used for monitoring a cabin of a wind turbine generator set. Background Art

[0002] Some wind farms are located at high altitudes and have humid climates. In winter, relative humidity can reach over 95%, and with frequent rain and snow, freezing weather is highly likely. Frost can cause ice to form on wind turbine blades, increasing their weight and changing their linear shape. This can cause the turbine to display a "high wind, low power" fault, leading to shutdown. Blade icing primarily occurs due to two reasons. First, after winter rain or snow, rain and snow adhere to the blade surface, forming ice under the influence of low temperatures (blade icing occurs when the temperature drops below 1-2 degrees Celsius, not just below 0 degrees Celsius). Second, moisture in the air, at low temperatures (around 0 degrees Celsius), adheres to the blade surface, forming ice, similar to condensation on window screens. After a turbine shuts down due to the "high wind, low power" fault, staff members confirm blade icing by using a telescope or observing the ambient temperature on-site. They then record the information and manually shut down the turbine remotely. Once the weather warms up and the ice begins to melt and fall off, team members will consider restarting the turbine based on on-site conditions. Since the unit is far away from the substation, a lot of time will be spent on starting and stopping the wind turbine after it freezes. The wind farm freezes frequently throughout the year. If the freezing and icing time can be reduced, the power generation efficiency of the unit will be effectively improved.

[0003] Due to the high temperatures and heavy rainfall in summer, some wind farms are significantly affected by typhoons, with maximum wind speeds reaching over 30 meters per second. Typhoons' high wind speeds and destructive power can easily cause wind turbine failures and downtime. On-site operations and maintenance personnel primarily rely on weather forecasts from the Meteorological Bureau for typhoon preparedness, lacking direct access to turbine monitoring data, which can lead to inaccuracies in emergency response. Typhoons often trigger wind turbine failures. Generally speaking, the difficulty of addressing wind turbine failures during typhoon weather leads to prolonged downtime, which in turn impacts wind farm power generation.

[0004] To sum up, it is mainly in special weather conditions such as freezing and typhoons that the wind turbine data cannot be directly obtained from the background, which leads to slow on-site response and affects the availability of wind turbines. Summary of the Invention

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0040] Example 1

[0041] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a barometer for monitoring a wind turbine nacelle, comprising a detection assembly 100, which includes a fixing bracket 101 mounted on the outside of the wind turbine nacelle and a barometer body 102 mounted above the fixing bracket 101. The barometer body 102 is connected to the fixing bracket 101 via a threaded nut 103. The barometer body 102 is connected to the main controller inside the wind turbine nacelle via a wire, and the main controller is equipped with a surge protector. The wind turbine nacelle includes a cabin control cabinet, and the power interface on the cabin control cabinet is connected to the barometer body 102 to provide power. The main controller is located inside the cabin control cabinet, and the barometer body 102 is connected to the main controller via a surge protector. The main controller includes an input / output module, which transmits signals to the monitoring platform system via the input / output module.

[0042] Since freezing is not only affected by low temperatures but also by air humidity, a monitoring device that collects real-time air humidity changes can be used to promptly respond to changes in freezing. Typhoons are related to air pressure. When a typhoon approaches, the air pressure drops. If a device can monitor air pressure changes in real time, the typhoon's changes can be quickly monitored.

[0043] Specifically, the fixing bracket 101 is an anemometer bracket, and the barometer body 102 installed on the fixing bracket 101 is powered by a power interface on the cabin control cabinet.

[0044] The pressure signal and humidity signal of the barometer body 102 are then connected to the main control channel on the main controller for monitoring. On this basis, since some wind farms are located in high-altitude mountainous areas, there are many thunderstorms in summer and the thunderstorm season is long, the risk of equipment being struck by lightning is relatively high. Therefore, a surge protector can be installed in the main controller, so that the barometer body 102 is connected to the main controller after passing through the surge protector, so as to protect the equipment from lightning strikes.

[0045] The received signal of the barometer body 102 is transmitted to the background SCADA monitoring platform system. The current values of air pressure and humidity can be intuitively monitored on the background monitoring system. The operation and maintenance personnel on duty can capture the external environment of the wind turbine blades at any time through the background, thereby saving the time and labor costs of the operation and maintenance personnel.

[0046] The barometer body 102 is preferably a Bellamy barometer.

[0047] refer to Figure 3 , which is a comparison chart of the power loss caused by freezing of two fans before and after the installation of the barometer.

[0048] By comparing and analyzing the results in extreme weather with those of other units that are not equipped with Beiliang barometers, we came to the conclusion that "when typhoon weather occurs, the specific pressure value of the barometer can be used to determine the main wind direction of the wind farm, so that the wind turbine unit can yaw and feather in time to avoid damage to the wind turbine caused by excessive instantaneous wind speed."

[0049] At the same time, after the typhoon gradually subsides, the wind turbine can be yawed in time according to the changes in air pressure on the barometer, so that it can be turned into a power generation state, thereby improving the availability of the unit.

[0050] Similarly, when freezing occurs in winter, the humidity and temperature changes at the fan location can be observed based on the real-time data of the barometer. When the fan start-up conditions are met, the start-up action can be completed to improve the fan's availability.

[0051] Improve the level of safety management. Due to the freezing of fans, the frequency of on-site inspections of vehicles is relatively high every year, which also creates safety hazards.

[0052] On the one hand, because the mountain roads are rugged and covered with ice, vehicles are very likely to slip when personnel go to inspect the units, causing traffic accidents; on the other hand, there is thick ice on the wind turbine blades, and operation and maintenance personnel are easily injured by the ice when inspecting on site.

[0053] By installing the "Beliang Barometer", operation and maintenance personnel can monitor the on-site air pressure and humidity conditions in the background, thereby judging the blade icing situation, greatly reducing the occurrence of unsafe incidents and improving the safety management level of the wind power site.

[0054] The anti-loosening assembly 200 includes a housing 201 mounted on a fixing frame 101, a rubber damping strip 202 provided on the housing 201, the rubber damping strip 202 being used for extrusion contact with the nut 103, and a reminder assembly 300 for detecting looseness of the nut 103 being installed on the first end of the rubber damping strip 202. The anti-loosening assembly 200 also includes a housing 201 fixed to the fixing frame 101, a damping chamber 201a is provided on the outer side of the housing 201 at a position corresponding to the nut 103, the damping chamber 201a is used to accommodate the nut 103, and the rubber damping strip 202 is located in the damping chamber 201a. A first slider 202a is fixed to the first end of the rubber damping strip 202, a first chute is provided inside the housing 201 to accommodate the sliding of the first slider 202a, and a first tension spring 202c is fixedly connected between the first chute and the first slider 202a. The reminder component 300 includes a resistor bar 301 arranged along the sliding direction of the first slider 202a. The resistor bar 301 is fixed inside the shell 201. A resistor contact block 303 is in sliding contact above the resistor bar 301. The resistor contact block 303 is fixed on the first slider 202a. The resistor bar 301 is connected to the main controller through the circuit board 302.

[0055] Since the barometer body 102 is installed at a high altitude, it is susceptible to wind and vibration and the nuts connecting it are easily loosened. Generally, it is repaired and maintained by manpower, which is time-consuming and labor-intensive.

[0056] By installing the anti-loosening component 200, contact detection can be performed on the nut, so when the nut is loosened, a signal can be sent in time to notify the maintenance personnel, thereby avoiding the occurrence of hidden dangers.

[0057] refer to Figure 4-7 First, connect the nut 103 to the barometer body 102 to fix the barometer body 102, and then fix the shell 201 to the fixing frame 101 with bolts. The rubber damping strip 202 on the shell 201 is squeezed by the nut 103 and deformed, and is recessed in the damping cavity 201a. The rubber damping strip 202 is affected by the first tension spring 202c and the second tension spring, so it fits tightly with the nut 103, increasing the friction force.

[0058] by Figure 7For example, when the nut 103 becomes loose, the nut 103 rotates counterclockwise. While the nut 103 rotates, the friction force pushes the first slider 202a on the rubber damping strip 202 to move to the left. The first slider 202a drives the resistor contact block 303 to slide. The stroke of the resistor contact block 303 on the resistor bar 301 changes, resulting in a change in the resistance value, which changes the current output by the reminder component 300. The main controller feeds back the current signal to the monitoring platform system, which can directly determine whether the nut structure is loose, effectively improving the portability of maintenance and inspection of the barometer body 102.

[0059] Example 2

[0060] Reference Figure 7-8 This is the second embodiment of the present invention. Unlike the previous embodiment, it further includes a second slider 202b fixed to the second end of the rubber damping strip 202. A second slide groove is defined within the housing 201 to accommodate the sliding movement of the second slider 202b. A second tension spring is fixed between the second slider 202b and the second slide groove. A force-applying assembly 400 is provided on one side of the second slider 202b to apply tension to the second slider 202b. The force-applying assembly 400 includes a force-applying slider 401 slidably disposed within the housing 201. The sliding direction of the force-applying slider 401 is consistent with the sliding direction of the second slider 202b. A pull rope 402 is fixed to one side of the force-applying slider 401. The end of the pull rope 402 away from the force-applying slider 401 is fixed to the second slider 202b. A roller is installed within the housing 201 to support the pull rope 402. A pull rope spring 403 is fixedly connected between the force-applying slider 401 and the housing 201. The force-applying slider 401 is provided with plug-in blocks 404 on both sides with the pull rope 402 as the center, and a compression spring 405 is sleeved on the outside of the plug-in block 404. One end of the plug-in block 404 is movable through the shell 201, and a slot for plugging with the plug-in block 404 is opened on the outside of the force-applying slider 401. A first electromagnet 406 is provided at the end of the plug-in block 404 away from the force-applying slider 401, and the first electromagnet 406 is connected to the circuit board 302.

[0061] When the rubber damping strip 202 is squeezed by the nut 103, the rubber damping strip 202 is deformed and pulls the first slider 202a and the second slider 202b respectively. The spring between the two provides a force, thereby increasing the friction damping between the rubber damping strip 202 and the nut 103. When the nut 103 is loosened to the maximum angle, for example, 3°-8°, the first slider 202a drives the resistor contact block 303 to slide to the maximum stroke, so that the reminder component 300 outputs the maximum current.

[0062] The reminder component 300 inputs an increased current into the first electromagnet 406, which increases the magnetic force of the first electromagnet 406. The magnetic force generated by the first electromagnet 406 overcomes the elastic force of the compression spring 405 and its own damping, and the plug-in block 404 contracts to release the constraint on the force-applying slider 401. The force-applying slider 401 slides under the pull of the pull rope spring 403. When the force-applying slider 401 slides, the pull rope 402 pulls the second slider 202b, thereby increasing the tension applied by the second end of the rubber damping strip 202, so that the rubber damping strip 202 not only drives the nut 103 to rotate clockwise to retighten it, but also further increases the damping between the nut 103 to avoid slipping.

[0063] Secondly, the roller can avoid friction loss between the pull rope 402 and the outside world, thereby increasing the service life.

[0064] A detachable maintenance plate is installed above the housing 201 , so that the staff can not only repair the internal components by removing the maintenance plate, but also manually reset the force-applying slider 401 .

[0065] Example 3

[0066] Reference Figure 9 This is the third embodiment of the present invention, further providing a barometer for monitoring a wind turbine nacelle. The barometer includes a rubber damping strip 202 with a cavity 202d defined therein. Cavity 202d is filled with a medium. A magnetic strip is secured to the side of the rubber damping strip 202 away from the nut 103. A second electromagnet 201b is mounted within the damping cavity 201a and connected to a circuit board 302.

[0067] When the surface of the rubber damping strip 202 is damaged after long-term use, the damping between the rubber damping strip 202 and the nut 103 becomes weaker. Therefore, a medium is added inside the rubber damping strip 202 so that when the rubber damping strip 202 is damaged, the medium inside the rubber damping strip 202 flows out. The medium is preferably a viscous solution, so the flowing medium will cause adhesion between the rubber damping strip 202 and the nut 103, thereby fixing the nut 103 and preventing the nut 103 from slipping due to insufficient damping.

[0068] In addition, the second electromagnet 201b is connected to the reminder component 300, so when the current increases, the repulsive force generated by the second electromagnet 201b on the magnetic strip becomes greater, thereby squeezing the rubber damping strip 202, improving the tightness of the fit between the rubber damping strip 202 and the nut 103, and further improving the degree of bonding between the nut 103 and the rubber damping strip 202.
