[0024] The present invention will be further described below with reference to specific embodiments:

[0025] Implementation method 1:

[0026] This embodiment 1 provides a strong wind simulation device for impacting curtain walls, used to simulate strong winds and debris for curtain walls.

[0027] See Figures 1 to 3The strong wind simulation device of this embodiment 1 mainly includes a lifting trolley 1 and a strong airflow generating device 20.

[0028] The lifting trolley 1 is a piece of existing technology equipment, which is based on a roller trolley and has a lifting platform 11 installed on the roller trolley.

[0029] The strong airflow generator 20 is integrally mounted on the lifting platform 11 of the lifting trolley 1. The front end of the strong airflow generator 20 has an air outlet. Figure 1 (As indicated by the middle arrow A), this air outlet is a high-pressure outlet, capable of outputting high-pressure airflow. For ease of qualitative description, this air outlet is defined as a high-pressure airflow outlet. Several control devices are located at the rear end of the high-pressure airflow generator 20, mainly including a main power switch 4, an airflow adjustment switch 6, and an operation panel 5. These control devices are used to control the high-pressure gas generator inside the high-pressure airflow generator 20.

[0030] The airflow regulating switch 6 is essentially a potentiometer. The airflow regulating switch 6 is used to adjust the pressure of the output airflow at the strong airflow outlet (the airflow output from the airflow outlet of the high-pressure gas generator).

[0031] The operation panel 5 is used to input some operating parameters of the high-pressure gas generator.

[0032] In addition, a screen protector 51 is provided for the operation screen 5. The screen protector 51 is made of transparent plexiglass and is mounted on the rear end of the strong airflow generator 20 by a hinge. The screen protector 51 can be flipped up and down and is used to protect the operation screen 5 from external impact.

[0033] A launch button 3 is also provided on the lower side of the rear end of the high-pressure gas generator 20. The launch button 3 is used to start the high-pressure gas generator 20 to blast out a high-pressure gas from the high-pressure gas outlet (the gas output pipe of the high-pressure gas generator).

[0034] The combination of the launch button 3, the main power switch 4, the operation panel 5, and the airflow adjustment switch 6 constitutes a control interface. Through this control interface, the high-pressure gas generator 20 can be controlled, enabling the high-pressure gas generator 20 to eject a high-pressure gas flow from the high-pressure gas outlet.

[0035] More specifically, a high-pressure gas generator, a product of existing technology, is installed inside the high-pressure gas generating device 20. This high-pressure gas generator has a high-pressure gas inlet and a gas outlet. The high-pressure gas inlet of the high-pressure gas generator is connected to a compressed air supply source, which provides compressed air to the high-pressure gas generator, pressurizing it. The high-pressure gas generator also contains numerous airflow control devices, such as on / off valves, flow control valves, pressure relief valves, pressure sensors, temperature sensors, etc. These are all existing technology features and will not be described in detail further.

[0036] It should be noted that the compressed air supply source refers to any equipment or pipeline capable of providing compressed air supply. A quick exhaust valve is installed at the airflow output port of the high-pressure gas generator, and this quick exhaust valve is controlled by the launch button 3.

[0037] The high-pressure gas outlet is connected to the gas output port of the high-pressure gas generator. When the launch button 3 is pressed, the rapid exhaust valve is quickly opened, allowing the high-pressure gas inside the high-pressure gas generator to be discharged from the high-pressure gas outlet, thus forming a high-pressure gas flow. When the launch button 3 is released, the rapid exhaust valve is quickly closed, and the high-pressure gas flow outlet stops outputting gas.

[0038] In summary, the strong airflow generator 20 has a strong airflow outlet and is equipped with a control interface (including a launch button 3, a main power switch 4, an operation panel 5, an airflow adjustment switch 6, etc.). The function of the strong airflow generator 20 is to control the strong airflow generator 20 through the control interface so that the strong airflow generator 20 can blast out a strong airflow from the strong airflow outlet.

[0039] A launching tube 8 is provided at the front end of the strong airflow generating device 20. The rear end of the launching tube 8 is fitted onto the strong airflow outlet of the strong airflow generating device 20, and the front end of the launching tube 8 serves as a simulated strong wind output outlet facing forward.

[0040] The transmitting tube 8 has two functions.

[0041] The first function is to generate the strong airflow emitted by the strong airflow generator 20, thereby outputting a directional simulated strong wind.

[0042] The second function is to place simulated debris, so that the output simulated strong winds can carry the simulated debris.

[0043] Furthermore, in this embodiment 1, a steel ball launching end 81 is provided at the simulated strong wind output port of the launching tube 8, and a plurality of ball launching tubes 82 are also provided on the steel ball launching end 81, all of which face forward.

[0044] The function of the steel ball launching end 81 and its launching tube 82 is to launch steel balls.

[0045] Specifically, the steel ball launching head 81 has a large inner cavity for storing steel balls, and the ball-firing tube 82 is connected to the inner cavity of the steel ball launching head 81. When the steel ball launching head 81 is installed at the simulated strong wind outlet of the launching tube 8, the inner cavity of the steel ball launching head 81 is also connected to the launching tube 8. In this way, when the launching tube 8 emits simulated strong wind, the strong airflow can cause the steel balls in the steel ball launching head 81 to be launched out through the ball-firing tube 82, thereby simulating the scenario of natural strong wind carrying large-mass hard particles and impacting the curtain wall.

[0046] It should be noted that in other embodiments, the transmitting tube 8 may also be a conventional straight tube.

[0047] The strong airflow generator 20 is also equipped with a laser ranging probe 7. The laser ranging probe 7 is oriented in the same direction as the simulated strong wind output port of the transmitting tube 8. The laser ranging probe 7 is used to measure the distance between the strong wind simulation device and the target object.

[0048] In this embodiment 1, the target of bombardment is the glass curtain wall.

[0049] The strong airflow generator 20 is also equipped with a warning light 9, which is used to "issue warning information based on the operating status of the strong wind simulator" to warn surrounding personnel not to approach when the strong wind simulator starts operating.

[0050] In this embodiment 1, the strong wind simulation device is used to simulate the destructive impact of strong winds (such as hurricanes or tornadoes) on the curtain wall, that is, to conduct destructive tests on the curtain wall to test its performance in resisting strong wind damage, thereby providing reliable data support for the optimized design of the curtain wall.

[0051] The working principle of the strong wind simulation device in Embodiment 1 for conducting destructive tests on curtain walls is as follows:

[0052] The simulated fragments used for the test (usually a mixture of wood strips, gravel, hard particles, etc.) are placed in the launch tube 8. The launch parameters, such as launch pressure and launch time interval, are set through the control interface on the strong airflow generator 20. The simulated strong wind output port of the launch tube 8 is directed toward the target object (glass curtain wall).

[0053] After all the preparatory work is completed, start the compressed air supply source to charge the high-pressure gas generator in the strong airflow generating device 20 until the gas pressure in the high-pressure gas generator reaches the set requirement.

[0054] Pressing the launch button 3 will cause the high-pressure gas in the high-pressure gas generator to burst outward from the launch tube 8 instantly, thus forming a strong airflow at the simulated strong wind output port of the launch tube 8, i.e., simulated strong wind. The simulated strong wind emitted by the launch tube 8 carries simulated debris toward the target object. The simulated debris hits the target object with the help of the simulated strong wind, thus simulating the effect of "a strong wind in nature carrying various debris to impact the curtain wall, thereby causing damage to the curtain wall".

[0055] In addition, a radar detector can be specifically installed. This radar detector is mounted on a tripod next to the strong wind simulation device, with its detection direction facing the simulated strong wind output port of the transmitting tube 8. This radar detector is used to test the speed at which simulated debris impacts the target. The radar detector, combined with the strong wind simulation device, essentially constitutes a strong wind simulation test system for impacting a curtain wall.

[0056] The advantages of the strong wind simulation device and test system of this embodiment 1 are:

[0057] 1) The strong wind simulation device and test system of this embodiment can simulate the situation of "strong wind (such as hurricane or tornado) carrying debris and impacting the curtain wall", thereby providing reliable data support for the performance testing and optimization design of the curtain wall.

[0058] 2) By precisely controlling the various parameters of the strong wind simulation device, experiments can be conducted under different wind speeds and debris impact conditions, meeting diverse experimental needs and helping to conduct in-depth research on the damage mechanism of curtain walls under extreme weather conditions.

[0059] 3) The application of radar detectors has improved the efficiency of experiments and the accuracy of data, and facilitated experimental operation and data analysis.

[0060] Implementation Method 2:

[0061] The initial concept of the strong wind simulation device of this invention is introduced in Embodiment 2:

[0062] Brief overview:

[0063] This embodiment 2 discloses a wind-gun experimental device for simulating the impact of hurricanes or tornadoes on curtain walls, belonging to the technical field of building curtain wall performance testing equipment. The device includes a wind-gun system, an air pressure regulation system, a debris launching and recovery system, and a curtain wall specimen installation and measurement system. The wind-gun system launches simulated debris using a high-pressure air source and an air cannon; the wind speed simulation system uses multiple sets of fans to create different wind fields; the debris launching and recovery system provides various simulated debris and achieves debris recovery; and the curtain wall specimen installation and measurement system is used to install specimens and measure various parameters. The wind-gun experimental device of this embodiment 2 can realistically simulate the wind force and debris impact in hurricanes or tornadoes, providing reliable data support for curtain wall performance testing and optimized design. It has advantages such as comprehensive experimental conditions, precise control of experimental parameters, high experimental efficiency, and accurate data.

[0064] Regarding existing technologies:

[0065] Under extreme weather conditions such as hurricanes or tornadoes, curtain walls are subjected to powerful winds and the impact of debris carried by the wind, leading to damage and affecting the safety and normal use of the building. Currently, research on the performance of curtain walls under hurricane or tornado conditions lacks an experimental device capable of accurately simulating wind force and debris impact in real-world scenarios. Existing testing equipment either only simulates wind force and cannot effectively simulate debris impact, or the simulated debris impact differs significantly from actual conditions, failing to accurately assess the performance of curtain walls under extreme weather conditions. Therefore, developing an experimental device that can realistically simulate the impact of hurricanes or tornadoes on curtain walls is of significant practical importance.

[0066] Technical solution adopted:

[0067] (1) Principle: Utilizing the principle of aerodynamics, with air as the working medium, the air pressure energy is instantly converted into the air jet kinetic energy through the differential pressure device and the fast exhaust valve, generating a powerful impact force to launch simulated debris. It can simultaneously simulate the wind force and debris impact in hurricanes or tornadoes, more realistically restoring the impact of extreme weather on curtain walls, and providing more comprehensive and accurate experimental conditions for curtain wall performance testing.

[0068] (2) Composition of the air gun system: including high-pressure air source, air gun body, laser rangefinder, moving object radar detector, launch tube and control device.

[0069] The high-pressure air source is used to provide high-pressure air to power the air cannon.

[0070] The air cannon releases high-pressure air instantly under the command of the control device, propelling the simulated debris in the launch tube out at high speed. Driven by the high-speed airflow, the simulated debris impacts the curtain wall specimen with speed and impact force close to that of debris in a real hurricane or tornado. During this process, the radar detector accurately measures and records the speed of the impacting object when it hits the curtain wall.

[0071] (3) Features: The impact force can be controlled by adjusting the air supply pressure. It can launch simulated fragments of different masses and sizes. The launch speed is relatively high and can simulate the impact of fragments under high wind speed. For example, the wind-resistant debris detection equipment for building curtain walls is designed according to relevant standards. The working pressure of the air cannon is 0.4-0.8MPa, which can launch a steel ball with a mass of 2g±0.1g at a speed of 39.7m / s.

[0072] Specific ideas:

[0073] An experimental device for simulating the impact of hurricanes or tornadoes on curtain walls, the air gun system includes a high-pressure air source, an air gun body, a launch tube, and a control device, for launching simulated debris.

[0074] The wind pressure simulation system is activated by adjusting the potentiometer to the required release pressure and pressing the start button on both sides simultaneously.

[0075] A curtain wall specimen installation and measurement system, including a mounting frame and sensors arranged thereon, is used to install curtain wall specimens and measure their various parameters during experiments.

[0076] In the air cannon system, the pressure range of the high-pressure air source is 0.0MPa-0.8MPa, and the control device can accurately set the firing pressure and firing time interval of the air cannon.

[0077] Adjustment of the wind pressure simulation system: Open the ball valve to prepare the air gun for inflation, put in the test object, set the parameters on the touch screen interface, adjust the potentiometer to the required release pressure, press the start button on both sides at the same time, and the air gun will start to operate.

[0078] Implementation steps:

[0079] 1. Operation of the air cannon system: First, check if the pressure of the high-pressure air source has reached the set value, and connect the air cannon body, launch tube, and control device. Select appropriate simulated fragments according to the experimental requirements and load them into the launch tube. Set the air cannon's firing parameters, such as firing pressure and firing time interval, through the control device. Start the high-pressure air source, and once the pressure stabilizes, trigger the air cannon to fire through the control device. The simulated fragments are propelled out at high speed by the high-pressure airflow.

[0080] 2. Adjustment of the wind pressure simulation system: Open the ball valve to prepare the air gun for inflation, put in the test object, set the parameters on the touch screen interface, adjust the potentiometer to the required release pressure, press the start button on both sides at the same time, and the air gun will start to operate.

[0081] 3. Installation of Curtain Wall Specimen and Use of the Measurement System: Install the curtain wall specimen on the mounting bracket, ensuring a secure installation. Connect all sensors and calibrate them. During the experiment, the sensors collect various parameters of the curtain wall in real time and transmit the data to the data acquisition system. The data acquisition system processes and stores the data. After the experiment, the data is analyzed and evaluated to draw conclusions about the curtain wall's performance under simulated hurricane or tornado conditions.

[0082] Technical Highlights

[0083] (1) By precisely controlling the wind gun system and the wind speed simulation system, experiments can be conducted under different wind speeds and different fragment impact conditions, meeting diverse experimental needs and helping to study the damage mechanism of curtain walls under extreme weather conditions.

[0084] (2) The application of radar system has improved the efficiency of experiments and the accuracy of data, and facilitated the operation of experiments and data analysis.

[0085] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
