Description

Technical Field

[0001] The invention belongs to the technical field of building detection, and in particular is directed to a wind load monitoring method and an early warning system for steel frame buildings. Background Art

[0002] Portal frame buildings have a wide range of applications in a variety of sectors including industry, logistics and recreational facilities. This building type is particularly popular because its design does not require internal support columns, allowing for large amounts of open space. However, this also makes portal frame buildings particularly vulnerable to natural disasters, especially wind loads.

[0003] Currently, there are a variety of methods for evaluating the stability and safety of such structures. Among these methods, the authorization announcement number CN 113900381 B describes a remote health monitoring platform based on the Internet of Things that provides real-time, automated wind load monitoring for building structures. This monitoring system focuses mainly on global wind loads, that is, wind load measurements are performed on the entire building through a highly distributed sensor network.

[0004] However, this monitoring platform has several significant limitations:

[0005] 1. Inconsistency of response mechanisms: Although these systems can provide real-time data and early warnings, in actual applications, there is often a break in the coordination of early warning and response mechanisms. In other words, although the system can identify potential risks, it cannot directly trigger response mechanisms, such as automatically locking doors and windows or adding additional support structures. One of the main challenges is to design reliable power sources and lines arranged at high altitudes and outdoors. These components are susceptible to long-term erosion, resulting in increased maintenance costs. Therefore, it is not easy to achieve the coordination of response mechanisms in actual applications;

[0006] 2. Neglect of local wind loads: Most existing systems fail to fully consider the local structure of the building, especially the sides and highest points, where wind loads are often much higher than the average. This leads to unforeseen structural instability of the building during storms or other extreme weather events;

[0007] 3. Lack of automatic response mechanism: Existing wind load monitoring systems usually do not include automatic response mechanisms, such as automatically strengthening structures or issuing emergency evacuation orders, which may lead to unnecessary risks under rapidly changing climate conditions.

[0008] In summary, although the existing portal frame building wind load monitoring technology has made some progress in some aspects, there are still some problems that need to be improved. In order to solve these problems more effectively, it is necessary to comprehensively consider the impact of global and local wind loads and introduce a more coordinated and automated response mechanism to improve the stability and overall safety of portal frame buildings under severe climatic conditions. Summary of the invention

[0009] In view of the above problems, the present invention provides a local wind guide device and a corresponding steel frame building wind load warning system, which effectively reduce the impact of wind load on the building structure and introduce an automated response mechanism to improve the stability and safety of the building under severe climatic conditions.

[0010] The invention object of the present invention is achieved through the following technical solutions: A local wind deflector device for reducing the influence of wind load on building structure, characterized by comprising: at least one deflector plate, the top of which is rotatably connected to the building frame, at least one fan-shaped rotating arm is fixedly connected to the top of the deflector plate and is coaxial with the axis of rotation;

[0011] A transmission device, wherein a transmission belt is connected to one end of the fan-shaped rotating arm, and the other end of the transmission belt passes downward through a rotating pulley group and then turns upward to be fixedly connected to the downward end of the guide plate;

[0012] A connecting bar, one end of which is connected to the driving belt and the other end of which is connected to the weight, and has an interference notch for interacting with the stop device;

[0013] A stopper device has a main body including a locking tongue, which interacts with the connecting strip through an interference notch in a normal state;

[0014] Under the action of wind, the deflector swings due to the force of the wind, thereby unlocking the stopper, causing the connecting strip to fall, and the transmission belt drives the fan-shaped rotating arm to swing, and finally the deflector turns from a vertical position to an obliquely opened position, reducing the impact of wind on the building. Compared with the existing technology, the local wind deflector device can automatically adjust the angle of the deflector according to the direction and strength of the wind load through a flexible rotating structure and transmission device, thereby guiding the wind to the appropriate direction. This design can effectively reduce the impact of wind load on the building structure, improve the stability of the structure, and reduce the risk of wind disasters.

[0015] Preferably, the transmission belt has a spring to provide a buffer. The introduction of the spring mechanism can provide a buffer when the wind load changes, so that the movement of the deflector is smoother, the impact of sudden changes on the structure is reduced, and the stability and durability of the deflector device are improved.

[0016] Preferably, the pulley block includes two running tracks and a pulley frame, and at least two pulleys are located on the pulley frame. The pulley block can effectively transmit the transmission force, so that the guide plate can rotate smoothly. The design of the two running tracks increases the balance and stability of the device, ensuring that the movement trajectory of the guide plate is more reliable.

[0017] Preferably, the stopper has an escape notch to increase the flexibility of the device. The existence of the escape notch enables the device to respond to wind force more freely under wind load, reducing the impact on the stopper, thereby improving the reliability and stability of the device.

[0018] Preferably, the connecting strip is provided with a resistance notch, and when the connecting strip is pulled down, the resistance notch presses on the stop lock tongue. The design of the resistance notch enables the connecting strip to stably interact with the stop lock tongue, ensuring that the movement of the deflector can be reliably unlocked under the action of wind load, thereby ensuring the normal operation of the deflector device.

[0019] Preferably, the deflector can be returned from the obliquely opened position to the vertical position to adapt to different wind conditions. The deflector can be restored from the obliquely opened position to the vertical position to ensure that when the wind weakens or changes, the deflector device can be adjusted in time to maintain the best wind guiding effect.

[0020] Preferably, a mobile application is further included for remotely controlling the state of the device, receiving warning information and real-time monitoring the operating state of the device. The introduction of the mobile application enables the user to remotely monitor and control the state of the diversion device and receive warning information in time.

[0021] In view of the above problems, the present invention further provides a method for monitoring wind loads on steel frame buildings, comprising the following steps:

[0022] S1. Arrange multiple sensors at key locations of steel frame buildings, including beams, columns and connection locations, including wind speed sensors, wind direction sensors, pressure sensors and accelerometers;

[0023] S2. Continuously collect wind load related data obtained by sensors, including wind speed, wind direction, wind force and structural vibration data;

[0024] S3. transmitting the data to a central control center in real time and integrating it with external meteorological data to provide a comprehensive wind load analysis;

[0025] S4. Conduct comprehensive analysis on the received multi-dimensional data to evaluate the magnitude, directionality and distribution of wind loads;

[0026] S5. Use machine learning algorithms and historical wind load data to train models and accurately predict future wind load trends;

[0027] S6. Based on the forecast and real-time data, evaluate the impact of wind load on the structural stability of steel frame buildings and determine whether it exceeds the safety threshold;

[0028] S7. When the system predicts or detects that the wind load exceeds the safety threshold, a wind load warning signal is automatically generated;

[0029] S8. Display the warning signal through the central control center and push the warning information to the registered maintenance personnel through the mobile application;

[0030] S9. When strong wind load is detected, the wind protection device in the building is automatically activated to reduce the impact of wind load on the building structure;

[0031] S10. Mobile applications allow maintenance personnel to remotely control the building's security system.

[0032] In view of the above problems, the present invention also provides a steel frame building wind load early warning system, comprising the following components:

[0033] A variety of sensors are arranged at key locations of the steel frame building, including wind speed sensors, wind direction sensors, pressure sensors and accelerometers;

[0034] Central control center, used for real-time collection, analysis and processing of wind load related data acquired by sensors;

[0035] Early warning mechanism, based on real-time data analysis, evaluates the impact of wind load on the stability of steel frame building structures. When the system predicts or detects that the wind load exceeds the safety threshold, it automatically generates a wind load early warning signal;

[0036] Mobile application, used to display warning signals and push warning information to registered maintenance personnel;

[0037] wind protection for automated response;

[0038] The wind protection device comprises the local wind guide device as claimed in claim 1.

[0039] Preferably, the wind protection device also includes automatic closing of windows, automatic locking of doors and windows, and automatic reinforcement of structures; and the warning signal may include sound, light signal, vibration or text information.

[0040] In summary, the present invention has the following advantages compared with the prior art:

[0041] 1. Accurate response mechanism: The present invention introduces an automated response mechanism that can automatically activate the wind protection device when the wind load exceeds the safety threshold, thereby quickly reducing the impact of wind loads on buildings and reducing the risk of structural instability.

[0042] 2. Local wind load considerations: The wind load early warning system of the present invention is significantly different from existing systems in terms of its comprehensiveness and accuracy. Traditional systems tend to focus on monitoring the overall wind load, ignoring the special conditions of the local structure of the building, such as wind loads on the sides and the highest point. This neglect may lead to unforeseen structural instability in extreme weather events, thereby endangering the safety of the building.

[0043] However, the present invention, by introducing local wind deflectors and combining them with a detailed sensor network, can obtain wind load data for different parts of the building in real time. These data include not only the overall wind load conditions, but also the special wind load conditions on the sides and highest points of the building. Through comprehensive analysis and the application of machine learning algorithms, the early warning system can accurately predict and evaluate the impact of local wind loads on building structures and identify potential risks in advance.

[0044] This precise consideration of local wind loads enables the early warning system of the present invention to more accurately judge the stability of the building structure in extreme weather events and trigger the automatic response mechanism in a timely manner, such as starting the local wind diversion device to reduce the impact of wind loads. This not only improves the stability of the overall structure, but also ensures the safety of people and equipment inside the building. Therefore, the innovation of the present invention in considering local wind loads provides a reliable guarantee for the safe operation of steel frame buildings under severe weather conditions.

[0045] 3. Intelligent data analysis: Through machine learning algorithms, the early warning system of the present invention can use historical wind load data for model training and more accurately predict future wind load trends, thereby providing more reliable wind load early warnings and helping decision makers take effective protective measures.

[0046] 4. Real-time monitoring and remote control: The early warning system equipped with a mobile application allows maintenance personnel to remotely control the status of the wind protection device, receive early warning information and monitor the operating status of the device in real time, providing a more convenient means of operation and management.

[0047] 5. Comprehensive safety improvement: By comprehensively considering the impact of global and local wind loads and introducing an automated response mechanism, the present invention not only improves the stability of buildings under severe climatic conditions, but also greatly improves safety and reduces potential risks caused by wind loads.

[0048] In summary, the present invention has made innovations in the design of the local wind guide device and the steel frame building wind load warning system to address the deficiencies of the prior art, so as to achieve more efficient, accurate and reliable wind load management and protection, thereby providing more comprehensive safety for the building structure.

DETAILED DESCRIPTION

[0061] The present invention will be further described below with reference to the embodiments shown in all the accompanying drawings:

[0062] Example 1

[0063] A wind load monitoring method and early warning system for steel frame buildings. To comprehensively monitor the impact of wind loads in different dimensions, the system deploys multiple sensors, such as accelerometers and pressure sensors, at key locations of the building structure to form a distributed sensing network. The sensors collect and transmit multi-dimensional data, including wind forces in vertical and horizontal directions.

[0064] In addition, the system sets up a local wind guide device 100 at a high position on the side of the building. The device is not used to sense the wind direction, but to reduce the impact of wind load on the structure. Each distributed sensing network continuously monitors the changes in wind speed, wind direction and wind force in real time, and uploads the data to the central control center. The central control center comprehensively analyzes these multi-dimensional data to more comprehensively evaluate the impact of wind load and provide more detailed information in the early warning signal.

[0065] Through this system, maintenance personnel can have a deep understanding of the nature of wind loads and take corresponding measures to ensure the safety of the building structure. When strong winds are predicted to be coming, the system can automatically start the local wind guide device 100 to reduce the impact of wind loads on the structure. At the same time, the system will send early warning information to maintenance personnel so that they can quickly take necessary countermeasures to ensure the stability and safety of the building structure.

[0066] The monitoring items and system early warning items refer to the following table:

[0067] Indicators / Functions describe Wind speed monitoring The wind speed is measured by wind speed sensors to ensure the accuracy of wind load data. Wind direction monitoring Wind direction sensors measure the direction the wind is blowing, helping to predict the directionality of wind loads.

Wind load distribution monitoring Sensors are placed at different locations to monitor the distribution of wind loads on the building structure. Distributed Sensing Network A variety of sensors are arranged at key locations to form a sensing network to comprehensively monitor wind load conditions. Data collection and upload Sensors continuously collect data and upload it to the central control center for comprehensive analysis. Wind load impact assessment The central control center analyzes the data to assess the impact of wind loads on the building structure. Early warning signal generation Based on wind load data, detailed early warning signals are generated to indicate wind load changes.

Flow diversion device control Control the operation of local wind guide devices. Belt and Pulley Control Ensure the normal operation of the transmission belt and pulley set to achieve the swing control of the guide plate. Stop device function The stop device keeps the deflector in the normal position, ensuring the stability of the wind load warning system. Automated early warning system Integrate detection data and early warning functions to achieve automated wind load monitoring and early warning.

[0068] The layout of this steel frame building wind load warning system can be summarized as follows:

[0069] 1. Sensor placement and data collection: Various sensors are placed at key locations of the building structure, including wind speed sensors, wind direction sensors, pressure sensors, etc. These sensors continuously collect wind load-related data, such as wind speed, wind direction, and wind force.

[0070] 2. Analysis and evaluation: The central control center conducts comprehensive analysis and evaluation of sensor data to understand the extent of wind load impact on the building structure. This includes the size, directionality and distribution of wind load.

[0071] 3. Wind load warning signal generation: Based on the analyzed data, a detailed wind load warning signal is generated to indicate the changes and trends of wind load.

[0072] 4. Structural stability assessment: Assess the impact of wind loads on the stability of building structures and determine whether measures need to be taken to ensure the safety of the building.

[0073] 5. Automated wind guide device control: If strong winds are approaching, the system automatically starts local wind guide devices to reduce the impact of wind loads on the building structure.

[0074] 6. Early warning notification sending: Early warning information is sent to maintenance personnel to inform them about the impact that the predicted wind load may have on the building structure. This provides enough time for them to take necessary countermeasures.

[0075] 7. Maintenance personnel response: After receiving the early warning notification, the maintenance personnel will take appropriate measures, which may include strengthening the building structure, safely evacuating personnel, etc., to ensure the stability and safety of the building.

[0076] 8. Monitoring and adjustment: After the early warning stage, continue to monitor the wind load conditions and adjust the settings and measures of the early warning system according to actual conditions.

[0077] In general, this early warning system can provide timely warnings and take actions through multi-dimensional data collection, analysis and notification of maintenance personnel to ensure the stability and safety of steel frame buildings under adverse conditions such as strong winds.

[0078] Figure 1 A standard portal frame building is shown, the base of these buildings is the skirt wall 01, and the superstructure is the building frame 02.

[0079] Now, let us consider the detailed structure and function of the local wind guide device 100:

[0080] 1. Guide plate: A guide plate 20 is provided, and the guide plate is preferably in a rectangular structure. The top of the guide plate is rotatably connected to the building frame 02 through a component, and at least one fan-shaped rotating arm 21 is fixedly connected to the rotatable axis position of the guide plate. One end of the arc surface of the fan-shaped rotating arm 21 faces upward and is perpendicular to the axis of rotation of the guide plate.

[0081] 2. Transmission device: A transmission belt 22 is attached to the arc surface of the fan-shaped rotating arm 21 and one end of it is fixed to the arc surface of the fan-shaped rotating arm 21. The transmission belt is finally connected to the downward free end of the deflector after being rotated through the pulley block 30. The pulley block 30 is slidably limited to the outer surface of the building structure, that is, the deflector 20, the fan-shaped rotating arm 21, the pulley block 30, and the transmission belt 22 together constitute an action mechanism. In addition, there is a connecting strip 23 for hanging heavy objects fixed on the transmission belt 22, and the connection point between the connecting strip 23 and the transmission belt 22 is located between the fan-shaped rotating arm 21 and the pulley block 30.

[0082] 3. Normal state: In the absence of wind, the deflector 20 maintains a slight distance from the side wall of the building. The tail of the connecting strip 23 is close to the skirt wall 01, hung with a weight, and connected to a stopper 50, whose structure can be similar to the locking device of an umbrella, and can be locked or unlocked by pulling down the weight on the connecting strip 23.

[0083] 4. Strong wind response: When strong winds come, the deflector 20 will swing due to the force of the wind, which will cause the stopper 50 to unlock. The connecting strip 23 drives the transmission belt 22 to move downward, so that the fan-shaped rotating arm 21 rotates upward, which causes the pulley block 30 to move upward, and finally the deflector 20 is turned from the vertical position to the oblique open position. At this time, the wind blowing towards the building will be guided, and this transformation helps reduce the direct impact of the wind on the building, thereby protecting the entire building.

[0084] 5. Pulley block design: The pulley block 30 includes two upper-limited running tracks 31, a pulley frame 32, and at least two pulleys. One pulley is used for rotation, and the other is used as a transition. The pulley used for rotation is provided with a spring to provide a buffer.

[0085] 6. Details of the stopper: The stopper 50 has a long columnar body 51, which faces the pulley frame 32 and presents a specific angle when the deflector 20 is flat against the side of the building. This design helps to trigger the locking or unlocking function of the stopper when needed. There is a cavity inside the body 51, which is suitable for placing accessories. The lock tongue 52 is partially hidden in the device body 51 and partially exposed, interacting with the notch 55 on the connecting strip 23 to complete the locking or unlocking action.

[0086] 7. Interference design: The connecting strip 23 is equipped with an interference notch 55, which presses on the stop tongue 52 when the weight is pulled downward. In addition, an interference inclined block 56 is fixed to the pulley frame 32, and its inclined surface contacts the lower part of the slide bar 541 to ensure a certain height on the walking track 31.

[0087] 8. Other key parts: Inside the stopper 50, there is a component 54 that can move up and down, which includes a slide bar 541, one end of which is exposed from the device body 51. The actuator 542 is fixed on the slide bar 541 and is provided with an inclined surface that matches the unlocking action surface 53. The end of the actuator is designed as a retractable and elastic reset hook 543 to ensure normal operation.

[0088] 9. Working principle: Under normal conditions, the deflector 20 is parallel to the building frame 02, and the stopper 50 is in a locked state to ensure the stability of the deflector. However, in strong winds, the wind force will cause the deflector to swing, triggering the unlocking mechanism of the stopper, allowing the deflector to rotate freely to an oblique position. This design does not consume energy, and more importantly, it does not require the use of power in harsh outdoor conditions for a long time, which will not only reduce the impact of the wind, but also ensure the safety and stability of the building.

[0089] In short, this wind guide device ensures the stability and safety of the portal frame building under various wind conditions through careful design and structural configuration.

[0090] The working principle of the local wind direction diversion device:

[0091] Structural state under normal conditions: In a windless state, the actuator 542 abuts against the unlocking action surface 53 due to the elastic effect of the slide bar 541. In this state, the exposed portion of the stop bolt 52 will not rotate or shift due to the effect of the downward pressure.

[0092] Wind action: When the wind force is strong enough to overcome the friction between the contact surface of the notch 55 and the stop tongue 52, the deflector 20 will move inward. This displacement will cause the stop device 50 to move accordingly. In this way, the bottom of the slide bar 541 will contact the oblique block 56, thereby receiving an upward thrust. Due to this thrust, the actuator 542 will move upward until the reset hook 543 on it contacts the unlocking action surface 53. Due to its elastic design, the reset hook 543 will be pushed to move, causing the stop tongue 52 to rotate downward and thus separate from the notch 55. This causes the connecting bar 23 to fall rapidly under the action of the weight hanging on it. At the same time, the transmission belt 22 will also move downward, driving the fan-shaped rotating arm 21 to swing. The movement of the transmission belt 22 will also drive the pulley block 30 to move upward, causing the deflector 20 to rotate to an oblique angle position. This state helps to guide the wind flow and reduce the lateral pressure of the wind on the building.

[0093] Automatic reset: When the deflector 20 is no longer affected by strong wind, the elasticity of the reset hook 543 will help the stop lock tongue 52 return to its original position. The slide bar 541 will also return to its original position under the action of its internal spring.

[0094] Flexible locking design: In order to ensure that the wind direction diversion device can respond quickly under low wind force, a waist hole and an elastic rubber pad 60 are designed between the device body 51 and the stop lock tongue 52. This ensures that the wind force can unlock the device by only overcoming the resistance of the elastic rubber pad 60. In addition, there is an avoidance notch 70 near the unlocking action surface 53 of the stop lock tongue 52, which provides greater flexibility for the action.

[0095] Flexible counterweight design: Considering that the user may need to adjust the weight of the connecting strip 23 to adapt to different wind environments, a detachable counterweight frame 80 is designed. This frame can be flexibly filled with various heavy objects, such as water, stones, or designed as a flower bed.

[0096] Through the above careful design, this local wind direction diversion device can respond quickly to strong winds, effectively guide wind flow, and ensure the stability of the entire steel frame building.

[0097] Example 2: Intelligent wind load prediction and automatic protection response

[0098] To further enhance the system's real-time response capability and accuracy, existing meteorological data and machine learning techniques can be combined.

[0099] Meteorological data integration: The central control center not only receives real-time data from sensors, but also obtains forecast data from local meteorological departments. In this way, in addition to the wind load data of the building itself, external meteorological information can also be obtained to improve the foresight of early warning.

[0100] Machine learning algorithm: The system can use past wind load data to train models through machine learning algorithms to more accurately predict future wind load trends. When the model predicts that the possible wind load exceeds the safety threshold, the early warning system is automatically triggered.

[0101] Automated protective response: In addition to the automatic activation of the local wind guide device 100, wind shields or windows can also be set up inside the building. When the system detects strong wind loads, the windows are automatically closed or the wind shields are activated to minimize the impact of wind on the interior of the building.

[0102] Example 3: Wireless technology and mobile application integration

[0103] To enhance the mobility and responsiveness of maintenance personnel, wireless technology and mobile applications can be combined.

[0104] Wireless data transmission: All sensors are equipped with wireless data transmission function, which can transmit data to the central control center in real time. This eliminates the need for complex wiring and enhances the flexibility and scalability of the system.

[0105] Mobile application: Develop a mobile application corresponding to the early warning system. When the system generates an early warning signal, it is not only displayed in the central control center, but also pushed to all registered maintenance personnel through the mobile application. This ensures that maintenance personnel can get the early warning information instantly no matter where they are.

[0106] Remote control function: Mobile applications can also control some building security systems, such as windows and doors, so that maintenance personnel can remotely close windows or doors to reduce the impact of strong winds on the interior of the building.

[0107] Real-time data viewing: The mobile application can also view the data of each sensor in real time, helping maintenance personnel to more intuitively understand the current wind load conditions and make more targeted responses.

[0108] The above two embodiments are further expansions on the basic early warning system, combined with current scientific and technological means to improve the practicality, foresight and response speed of the system.

[0109] Steel frame building wind load monitoring method:

[0110] Step 1: Sensor Placement

[0111] Arrange a variety of sensors, including wind speed sensors, wind direction sensors, pressure sensors, and accelerometers, at key locations of the building structure, such as beams, columns, and joints. If wireless technology is used, ensure that the sensors have wireless data transmission capabilities, and set up wireless receivers in appropriate locations to ensure the stability of data transmission.

[0112] Step 2: Data Collection

[0113] The sensors continuously collect wind load-related data such as wind speed, wind direction, wind force, and vibration data of the structure.

[0114] The data is transmitted to the central control center in real time and integrated with meteorological data to provide a more comprehensive wind load analysis.

[0115] Step 3: Data Analysis and Evaluation

[0116] The central control center conducts a comprehensive analysis of the received multi-dimensional data to evaluate the size, directionality and distribution of wind loads.

[0117] By using machine learning algorithms and combining past wind load data for model training, future wind load trends can be predicted more accurately.

[0118] Evaluate the impact of wind loads on building structural stability based on forecasts and real-time data to determine if safety thresholds are exceeded.

[0119] Step 4: Wind load warning

[0120] When the wind load predicted or detected by the system exceeds the safety threshold, a wind load warning signal is automatically generated.

[0121] The warning signal is displayed through the central control center, and the warning information is pushed to all registered maintenance personnel through the mobile application.

[0122] Step 5: Automate your response

[0123] If a strong wind load is detected, the system automatically activates the local wind guide device 100 to reduce the impact of the wind load on the building structure.

[0124] Mobile apps allow maintenance staff to remotely control a building’s security systems, such as automatically closing windows or doors.

[0125] Step 6: Maintainer Response

[0126] After receiving the early warning notification, maintenance personnel will take appropriate measures, which may include strengthening the building structure, safely evacuating personnel, and initiating other protective measures.

[0127] Step 7: Continuous Monitoring and Adjustment

[0128] After the early warning phase, the system continues to monitor wind load conditions in real time.

[0129] Adjust the settings, thresholds and measures of the early warning system based on actual conditions and response effects to ensure the continued stability and safety of the building.

[0130] Step 8: Data storage and feedback

[0131] All collected and analyzed data are stored in a central database for future data analysis and research.

[0132] Evaluate monitoring methods and systems regularly or in specific circumstances, and make necessary adjustments and optimizations based on feedback.

[0133] This monitoring method combines advanced sensor technology, data analysis technology and automated control technology to ensure the stability and safety of steel frame buildings under harsh conditions such as strong winds.

[0134] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
