Simulate reality The equipment for testing the thermal resistance of clothing under wind, rain, snow, ice, high temperature, and extreme cold conditions is 3 meters long, 3 meters wide, and 4 meters high. An environmental chamber and a heated mannequin are used to conduct thermal resistance tests. (Thermal resistance: the thermal resistance of clothing refers to the total thermal resistance of the clothing as it dissipates heat from the body to the external environment through the boundary air layer between the clothing and the surrounding environment after the heated mannequin is dressed.) During the thermal resistance test, the heated mannequin is placed in the environmental chamber. The temperature is set to (body temperature - ambient temperature) ≥ 30°C, the humidity (RH) is set to 30%-50%, and the environmental chamber wind speed is set to (0.4±0.1) m / s. The environmental chamber requires airflow to achieve the required temperature and humidity; however, excessive wind speed can affect the thermal resistance test results. Utility Model Content

[0014] As attached Figure 1 , 2As shown, the intelligent environmental cabin wind speed adjustment device with real-time wind speed feedback of this utility model includes a movable frame 1 set inside the environmental cabin, wind-blocking components set on both sides and top of the movable frame 1, and several wind speed sensors 4 corresponding to the warm-body dummy installed inside the movable frame 1; the signal output terminal of the wind speed sensor is connected to the input terminal of the central processing unit, and the central processing unit adopts an embedded microcontroller (such as a PLC or a single-chip microcomputer); a roller assembly for adjusting the wind-blocking components is installed on the movable frame 1.

[0015] The scroll assembly of this utility model includes a first scroll assembly installed on one side of the movable frame 1, a second scroll assembly installed on the other side of the movable frame 1, and a third scroll assembly installed on both sides of the top of the movable frame 1. Specifically: the first scroll assembly includes a first upper scroll 21 rotatably installed on the outer side of the top of one side of the movable frame 1 and a first lower scroll 22 rotatably installed on the outer side of the bottom of the side; the second scroll assembly includes a second upper scroll 23 rotatably installed on the outer side of the top of the other side of the movable frame 1 and a second lower scroll 24 rotatably installed on the outer side of the bottom of the side; the third scroll assembly includes a third scroll A25 rotatably installed on the top of one side of the movable frame 1 and a third scroll B26 rotatably installed on the top of the other side of the movable frame 1; a small stepper motor 5 is respectively installed at one end of the first lower scroll 22, the second lower scroll 24, and the third scroll A25 to rotate the first lower scroll 22, the second lower scroll 24, and the third scroll A25 accordingly.

[0016] The wind-blocking assembly includes a first wind-blocking mantle 31 wound on a first lower roller 22, a second wind-blocking mantle 32 wound on a second lower roller 24, and a third wind-blocking mantle 33 disposed on a third roller A25 and a third roller B26. The free end of the first wind-blocking mantle 31 hangs down after passing over a first upper roller 21, and a first counterweight 34 is disposed on both sides of the free end of the first wind-blocking mantle 31. The free end of the second wind-blocking mantle 32 hangs down after passing over a second upper roller 23, and a second counterweight 35 is disposed on both sides of the free end of the second wind-blocking mantle 32. The third wind-blocking mantle 33 is wound in a ring on the third roller A25 and the third roller B26. That is, the third wind-blocking mantle 33 is a two-layer design, without the need for a single-layer wind-blocking mode. A small stepper motor 5 drives the third roller A25 to rotate, which in turn drives the third wind-blocking mantle 33 to rotate for corresponding fine adjustment of the aperture. The first wind-blocking curtain 31, the second wind-blocking curtain 32, and the third wind-blocking curtain 33 are made of breathable mesh fabric with a pore size of 0.5-1.2mm and a porosity of 30-60%.

The pores of the wind-blocking curtains effectively regulate wind speed while ensuring sufficient air permeability, minimizing interference with the original temperature and humidity field uniformity and control accuracy of the environmental chamber, achieving simultaneous attainment of wind speed and temperature / humidity standards, and meeting the required temperature and humidity requirements around the warm-body dummy.

[0017] As attached Figure 2 As shown, the mobile frame of this utility model includes several sets of inverted U-shaped frames 11 arranged at intervals. The side columns of two adjacent inverted U-shaped frames 11 are fixedly connected by cross-shaped connecting rods 12. Universal wheels 13 are installed at the bottom of each inverted U-shaped frame 11. In this embodiment, three wind speed sensors 4 are provided. The three wind speed sensors 4 are arranged in a ring and are installed in a corresponding manner on the inner side of each inverted U-shaped frame 11 through a ball universal connector 6.

[0018] This invention features three wind speed sensors (4) positioned approximately 0.5 meters from the dummy's chest, left shoulder, and right shoulder, ensuring the sensor probes are not obstructed by supports or netting and are directly facing the airflow direction. This provides real-time data accurately reflecting the wind speed in the working area, resulting in more reliable average value calculations and more comprehensive control data. A wind-blocking curtain controls the wind speed in the working area of ​​the warm-body dummy within the environmental chamber to within the range of 0.3-0.5 m / s, effectively regulating wind speed while ensuring sufficient air permeability. This minimizes interference with the original temperature and humidity field uniformity and control accuracy of the environmental chamber, achieving simultaneous compliance with wind speed, temperature, and humidity standards. The frame is equipped with universal locking casters at the bottom for easy movement and positioning, adapting to different sizes of environmental chambers and dummy positions. The entire device is a non-invasive add-on structure, requiring no modification to the original circulation system of the environmental chamber, offering flexible installation and low cost. The human-machine interface provides intuitive operation and data monitoring, while the communication interface facilitates integration with higher-level systems, enhancing the informatization and automation of the testing process.
