DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4The application discloses a modular low-damping meteorological direct-flow wind tunnel, comprising a convenient replacement mechanism, a blowing mechanism and a convenient moving mechanism, the convenient replacement mechanism comprises a mounting plate 1, the upper side of the mounting plate 1 is provided with a wind resistance pipe 2, the inside of the wind resistance pipe 2 is provided with a clamping groove 3, the inside of the clamping groove 3 is provided with an airflow baffle 4, one side of the wind resistance pipe 2 is fixedly connected with a closing plate 5 through screws, one end of the wind resistance pipe 2 is fixedly connected with a compression pipe 6 through screws, one end of the compression pipe 6 is fixedly connected with a fixing frame 7, one side of the fixing frame 7 is fixedly connected with a flexible bellows 8, one end of the flexible bellows 8 is fixedly connected with a contact frame 9, the inside of the contact frame 9 is provided with a threaded rod 10, the outside of the threaded rod 10 is provided with a nut 11, the airflow baffle 4 is in sliding connection with the clamping groove 3, the nut 11 is in threaded connection with the threaded rod 10, the threaded rod 10 is in sliding connection with the fixing frame 7 and the contact frame 9, the fixing frame 7 is fixedly connected to the upper side of the mounting plate 1, and the inside of the contact frame 9 is provided with a limiting groove 12. From the structure, the modular design makes the parts relatively independent and interrelated. For example, the wind resistance pipe 2, the compression pipe 6 and other components in the convenient replacement mechanism are combined through screw connection and other modes, when the closing plate 5 is disassembled, the airflow baffle 4 can be pulled out of the clamping groove 3. Compared with a traditional integral wind tunnel, the difficulty and cost of maintenance and upgrading are greatly reduced, the downtime of the wind tunnel caused by equipment maintenance is reduced, and the overall use efficiency of the equipment is improved. In the wind resistance pipe 2, the airflow baffle 4 plays an important role, the airflow baffle 4 is in sliding connection with the wind resistance pipe 2 through the clamping groove 3, and there are two airflow baffles 4 located at the upper and lower inner sides of the wind resistance pipe 2 respectively. By adjusting the position of the airflow baffle 4 in the clamping groove 3, the flow area and flow characteristics of the airflow in the wind resistance pipe 2 can be changed, so that different meteorological conditions can be simulated. For example, moving the airflow baffle 4 to the center of the wind resistance pipe 2 can reduce the airflow passing area, so that the airflow speed is accelerated, and vice versa, so that the airflow speed is reduced. Compared with the traditional wind tunnel, the design has obvious improvement in the flexibility of simulating meteorological conditions.

[0022] In one aspect of the embodiment, the blowing mechanism starts to run, the motor 14 at one end of the fixed rod 13 starts to work, drives the wind wheel 15 at the output end to rotate at high speed, the rotation of the wind wheel 15 promotes the surrounding air to flow, and airflow is formed. The airflow is gathered in the contact frame 9, under the action of pressure, the airflow pushes towards the compression pipe 6 since the flexible bellows 8 connects the contact frame 9 and the fixing frame 7, the compression pipe 6 plays a role in transition and preliminary regulation of the airflow, then the airflow enters the wind resistance pipe 2, and after the airflow passes through the wind resistance pipe 2, enters the experimental section 16, and experiments are carried out by experimenters.

[0023] In one aspect of this embodiment, a removable mechanism facilitates the overall movement and placement of the wind tunnel. Support rods 17 securely connect the mounting plate 1 to the base frame 18. Universal wheels 19 on the underside of the base frame 18 allow for flexible movement of the wind tunnel on the ground. Multiple reinforcement rods 20 further enhance the structural strength and stability of the base frame 18, making it easier to move the wind tunnel to the desired location for experiments. This overcomes the drawback of traditional wind tunnels, which are fixed and difficult to relocate, and improves the device's flexibility and site adaptability.

[0024] The working principle of the present invention is as follows: When the modular low-damping meteorological DC wind tunnel is in use, the air supply mechanism starts operating. The motor 14 at one end of the fixed rod 13 begins operating, driving the wind wheel 15 at its output end to rotate at high speed. The rotation of the wind wheel 15 causes the surrounding air to flow, forming an airflow. The airflow gathers inside the contact frame 9. Because the flexible bellows 8 connects the contact frame 9 and the fixed frame 7, the airflow is pushed toward the compression tube 6 under pressure. The compression tube 6 serves as a transition and preliminary airflow regulation. The airflow then enters the wind resistance tube 2. Finally, the airflow regulated by the wind resistance tube 2 enters the experimental section 16 fixed to one side by screws. The experimental section 16 is a key area for conducting various meteorological simulation experiments. Researchers can place experimental models or measuring instruments in it to accurately observe and analyze airflow parameters and simulated meteorological environments, providing reliable experimental data and research basis for meteorological science research, building wind engineering, atmospheric environment simulation, and other fields. All electrical equipment in this solution is powered by an external power supply.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
