Sandstorms and Shelter Forests
★Exhibit Content: Windbreak and sand fixation, ecological protection of shelterbelts ★Interaction: Electromechanical interaction ★Operation: Press the reset button, the annular airflow pushes the lightweight balls (sand dust) uniformly to the rear of the model, and all green shelterbelt models automatically fall down, simulating a bare land environment without vegetation protection; in the no-shelterbelt state, press the wind button, the fan blows out airflow, and the small ball sand dust is dispersed and spreads everywhere by the airflow, intuitively demonstrating the phenomenon of raging wind and sand; after reset, press the "Shelterbelt 1" button, a small local patch of shelterbelt rises, and when the wind blows again, only the sand dust in the small area is blocked; turn the side handwheel to change the direction of the wind nozzle, the protection area becomes ineffective, and sand dust scatters; after reset, press the "Shelterbelt 2" button, all shelterbelt models rise synchronously, and regardless of whether the handwheel is turned to adjust the wind direction, the airflow is blocked by the trees, and the sand dust will not be dispersed, fully demonstrating the ecological role of a continuous shelterbelt in windbreak and sand fixation. ★Exhibit Description: "Sandstorm and Shelterbelt" is a special-shaped desktop science popularization exhibit on the theme of ecological environment and soil and water wind-sand control. It belongs to the geographical environment and ecological protection science popularization exhibition area and is a recommended exhibit of the PopsciCat Exhibit Store. The exhibit adopts a dark gray special-shaped wavy floor-standing cabinet, with a white artificial stone operation area on the countertop, and a large hemispherical high-transparency acrylic dustproof protective cover in the center. Inside the cover are arranged liftable green tree models, swingable wind nozzles, and a lightweight ball sand dust simulation module. A metal adjustment handwheel and multiple sets of function control buttons are provided on the side. The interior of the cabinet integrates a fan air supply system, a shelterbelt lifting actuator, and PLC electrical control equipment. The exhibit uses a fan to simulate strong wind and balls to simulate sand dust, displaying the differences in wind-sand diffusion under three scenarios: no shelterbelt, partial shelterbelt, and continuous shelterbelt, intuitively explaining the ecological principle of trees blocking airflow, fixing sand, and resisting sandstorms, and popularizing environmental protection knowledge of afforestation for windbreak and sand fixation. ★Scientific Principle: When the surface lacks vegetation cover, the strong wind airflow is unobstructed and extremely

A continuous forest can divide and weaken the airflow speed, tree branches and trunks block the flow of wind and sand, reduce wind kinetic energy, and when sand and soil lose the wind's entrainment, they settle, achieving sand fixation and dust prevention. The protective effect is closely related to the scale of the forest. Scattered small shelterbelts can only block wind and sand from a single direction, while a complete continuous shelterbelt can resist winds from multiple angles, with comprehensive and stable windbreak and sand fixation effects. It is a core ecological means to combat desertification and sandstorms.
