Therefore, the research on wind field characteristics is of great significance. As an important part of it, wind field simulation is particularly important for the accurate simulation and measurement of building wind field characteristics. However, although traditional wind tunnel experiments can simulate the real wind field environment, they have problems such as large footprint, high cost, complex operation, and difficulty in achieving accurate measurement of proportionally reduced building models. Traditional wind field simulation methods mostly rely on computer simulation software, and their accuracy and reliability are limited by many factors. Therefore, the development of an experimental device that can simulate wind fields in a real environment is of great significance to improving the quality and efficiency of architectural design and urban planning.

However, this system needs to rely on the flight stability of drones and the reliability of data transmission, and is costly and complex to operate. Utility Model Content

[0016] In general, the above technical solutions conceived by the utility model have the following beneficial effects compared with the prior art:

[0017] 1. The bracket provided by the utility model is streamlined like a water droplet to reduce airflow interference and improve the reliability of experimental results. The longitudinal section is similar to an inverted wing section, that is, the upper surface is straight and the lower surface is curved. The design can firstly reduce the air resistance of the main body of the experimental device, so that the energy consumption of the vehicle is lower; secondly, the straight upper surface can be conveniently installed with various building models as research objects; due to the pressure difference between the upper surface and the lower surface, downforce can be generated, which is conducive to the high-speed and stable driving of the mobile unit;

[0018] 2. The airflow regulating unit in the utility model is provided with a plurality of array blocks for changing the distribution of airflow intensity, and the airflow distribution is precisely controlled: the array blocks can be arranged and combined to precisely control the airflow intensity and direction, ensuring that the distribution of airflow intensity can be adjusted according to the required gradient, so that the airflow can simulate a gradient distribution similar to an exponential curve, accurately imitating the urban wind field, with high flexibility and adjustability: the design of the blocks makes the airflow regulating unit highly flexible, and by adjusting the number, position and arrangement of the blocks, different airflow intensity distributions can be easily achieved to meet different experimental requirements, and the structure is simple and easy to manufacture and maintain: compared with complex airflow regulating devices, the block array has a simple design structure, low manufacturing cost, and convenient maintenance. The simplified structure reduces the complexity in production and use, improves the reliability and durability of the device, and the modular design is easy to replace and upgrade: due to the modular design of the block array, when the airflow distribution mode needs to be changed, it can be achieved by replacing or rearranging some blocks, which is convenient for updating and upgrading the experimental device, and improves the scalability and adaptability of the experimental device.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1 and 2 As shown, the utility model aims to provide a building wind field simulation experiment measurement device, which can use the airflow generated by the movement of the mobile unit 1 to perform wind field simulation experiment measurement on a proportionally reduced building model, thereby realizing accurate research on the building wind field characteristics.

[0029] Specifically, the device includes a bracket 2 mounted on a mobile unit 1, an airflow adjustment unit 3 fixed on the bracket 2, a building model 4, and a plurality of wind speed measuring probes arranged around the building model 4. The bracket 2 is made of lightweight materials to ensure the overall lightness and stability of the device. The building model 4 is scaled down in proportion to the actual building so as to simulate the wind field characteristics more realistically. The wind speed measuring probes are evenly distributed around the building model 4 to measure the wind speed changes at different locations in real time.

[0030] The main body of the bracket 2 adopts a streamlined design, which is based on aerodynamic principles and is obtained through CFD simulation optimization. The main purpose of the streamlined design is to reduce air resistance and improve the energy efficiency of the experimental device.

[0031] Bracket 2 adopts an inverted wing section design. The longitudinal section of bracket 2 adopts an inverted wing section design, that is, the upper surface is straight and the lower surface is curved. This design has the following characteristics. Straight upper surface: The straight upper surface provides convenience for installing various building models, and also helps to maintain the stability of airflow. In addition, the straight upper surface can also be used as a collection surface for experimental data, which is convenient for researchers to obtain accurate experimental data. Curved lower surface: The curved lower surface will generate an air pressure difference with the upper surface during the vehicle driving process, forming a certain downforce. This downforce helps the vehicle to maintain stability when driving at high speeds and reduce the bumps and shaking caused by airflow interference. At the same time, the curved lower surface can also guide the airflow to flow downward and reduce air resistance. Optimized cross-sectional proportions: The proportions of the inverted wing section have been carefully optimized to ensure good aerodynamic performance under different wind speed and wind direction conditions. By adjusting the curvature and length ratio of the upper and lower surfaces, researchers can simulate the wind field distribution of different vehicles under different conditions.

[0032] The surface of the bracket 2 of the utility model presents a smoothly transitional curve from the front end to the rear end, avoiding abrupt corners and edges to reduce turbulence and resistance during air flow. The cross section of the bracket 2 gradually changes from front to back, matching the velocity distribution of the airflow, which helps to maintain a stable airflow. The streamlined design takes into account the overall balance of the device, which not only optimizes the aerodynamic performance, but also ensures the stability and safety of the device when moving at high speed.

[0033] The airflow regulating unit is provided with a plurality of arrays of three-dimensional blocks 7, which are used to change the distribution of airflow intensity so that the airflow intensity is distributed in a gradient from top to bottom; the size of the three-dimensional blocks is designed according to the actual required airflow intensity.

[0034] In one embodiment of the utility model, in terms of material selection, the bracket is made of a lightweight and high-strength material, such as a carbon fiber composite material or an aluminum alloy. These materials not only have excellent mechanical properties, but also can reduce the weight of the device and improve energy efficiency. In the surface treatment of the bracket, the surface of the material is specially treated to improve its corrosion resistance and wear resistance. At the same time, the smooth surface treatment also helps to reduce air resistance and improve the performance of the device.

[0035] In order to facilitate the installation and replacement of building models and subsequent maintenance and upgrades, the main body of the device adopts a detachable and modular design. Modular components: The device consists of multiple modular components, each of which has independent functions and interfaces. By combining different components, experimental devices of different scales and complexities can be easily constructed. Quick disassembly and installation: The modular components are designed to be quickly disassembled and installed, which is convenient for researchers to quickly replace building models or perform other operations during the experiment. Standardized interface: All modular components follow a unified standardized interface design to ensure compatibility and interchangeability between different components. This helps to reduce maintenance costs and improve experimental efficiency.

[0036] like Figure 3 As shown, the airflow adjustment unit 3 and the building model are arranged on the upper surface of the bracket. The airflow adjustment unit is used to adjust the distribution of airflow intensity so that the airflow intensity is gradiently distributed from top to bottom; the building model is used to simulate urban buildings, and the real wind field at the urban buildings is realized by measuring the wind field at the building model.

[0037] In addition, the device also includes a data collector and a processor. The data collector is connected to the wind speed measurement probe and is used to collect wind speed data in real time. The processor processes and analyzes the collected data to obtain the wind field characteristic parameters of the building model.

[0038] In the early preparation stage of the experimental plan, detailed planning and preparation were carried out to ensure the accuracy and reliability of the wind field simulation experiment. Among them, the selection of key components such as the main form of the building wind field simulation experiment device and the crossbar 5 is particularly important.

[0039] In one embodiment of the utility model, after research and comparison, it was finally decided that a crossbar 5 with a standard T-slot made of aluminum alloy is used on the mobile unit 1. Aluminum alloy has the characteristics of light weight and high strength, and is very suitable for making components that need to withstand high-speed driving and wind force. It has a low density and light weight, which can reduce the weight of the entire experimental device and reduce the load on the mobile unit 1. At the same time, aluminum alloy has high strength and rigidity, and can withstand wind force and vibration during high-speed driving, ensuring stability and safety during the experiment. In addition to the choice of material, the design of the crossbar 5 is also optimized. The crossbar 5 adopts a streamlined design to reduce the resistance of airflow to it and increase its wind resistance. In addition, special clamps and T-screws are specially designed to ensure that the base of the experimental device can be firmly fixed on the crossbar 5 with a standard T-slot. These crossbars, clamps and screws are universal and adjustable, and can adapt to car luggage racks of different sizes and shapes, providing greater flexibility and convenience for experiments. Such as Figure 4 As shown in the figure, the handle 6 of the bracket is connected to the crossbar by using standard T-shaped screws, and the crossbar is provided with a mounting groove that matches the T-shaped screws.

[0040] In one embodiment of the utility model, the building model 4 is used to simulate urban buildings. The real wind field at the urban buildings is realized by measuring the wind field at the building model 4. The building model is made using high-precision 3D printing technology to ensure the accuracy and detail restoration of the model. The wind speed measurement system is the core part of the experiment. A highly sensitive and fast-responding thermal anemometer is selected, and the measurement points are reasonably arranged to fully capture the wind field information. The data collector transmits the real-time collected wind speed data to the processor, which processes and analyzes the data to obtain the wind field characteristic parameters of the building model. These parameters can be displayed in real time on the display screen, or stored in the memory inside the device for subsequent analysis and research.

[0041] In one embodiment of the utility model, a wind speed measuring probe is provided at the front end of the bracket for measuring the wind speed at the front end of the bracket; a searchlight is provided at the front end face or side face of the bracket.

[0042] During the implementation phase of the experimental program, the universal crossbar and fixtures are first installed on the luggage rack of the car according to the predetermined plan. Then, the building model is fixed on the fixed flat base device, and necessary adjustments are made to ensure its stability, and the base is fixed to the main device with screws. Next, the wind speed measurement unit is installed and carefully debugged to ensure that it can accurately measure the required wind speed data. At the same time, it is also equipped with a data collector, processor and data monitor to realize real-time collection, processing and monitoring of experimental data.

[0043] In one embodiment of the utility model, a car is used as a mobile unit 1, and the mobile unit conducts experiments at different speeds under different road conditions on the ground 8 to obtain rich wind field data. The data monitor can monitor the experimental data and device status in real time, and display them to researchers through a visual interface, so that they can intuitively understand the progress of the experiment and the results of data analysis. In addition, the device can also be connected to a remote computer or mobile phone and other devices through a wireless communication module to achieve remote monitoring and data transmission. The experimental process can be monitored in real time in a laboratory or a remote location, and experimental data can be obtained, which improves the flexibility and convenience of the experiment.

[0044] After the experiment, the collected data will be deeply analyzed and processed, and professional software or algorithms will be used to simulate the wind field and evaluate the building performance to draw experimental conclusions and provide valuable reference information for architectural design and urban planning. These conclusions and suggestions will not only help optimize building design and improve the building's wind resistance, but also provide a scientific basis for urban planning and promote the sustainable development of cities.

[0045] In addition, attention should also be paid to the maintenance and care of the equipment. Clean and inspect the equipment regularly to ensure that there is no dirt or damage on its surface. At the same time, perform regular maintenance and care on the equipment, such as replacing worn parts and lubricating the moving mechanism, to extend its service life and maintain stable performance.

[0046] In summary, the crossbar moving unit of this embodiment provides a relatively efficient, accurate and low-cost method for wind field simulation experiments. Through the building wind field simulation experiment measurement device of the utility model, it is possible to accurately measure the wind field characteristics of a proportionally reduced building model, providing strong experimental support for research in the field of building microclimate and fluid dynamics. At the same time, the device has the advantages of simple structure, easy operation and low cost, and is suitable for experimental research and teaching use in scientific research institutions, universities and other units. It will also help promote the innovative development of architectural design and urban planning, and make positive contributions to the progress of the industry.
