[0033] In the process of the embodiment, after the fan 416 is started, the fan 417 rotates to generate airflow. The airflow enters through the mounting round opening on the ventilation box 411, and then enters the inside of the demonstration cabin 311 through the rectangular ventilation opening on the fixed block 418 and the rectangular ventilation opening 312 on both sides of the demonstration cabin 311, to simulate the flow of wind on different terrain sand tables.

When the airflow generated by ventilation passes through the sand inlet hopper 412, the sand in the sand hopper can be brought into the ventilation box 411, and then enter the demonstration cabin 311 along with the airflow, to simulate sand and dust weather phenomena.

[0034] Working principle: the whole weather teaching demonstration device works cooperatively on the stable structure composed of the support pad 1 and the support block 2 through the sand table sliding installation part 3 and the weather simulation part 4, to provide an intuitive demonstration for weather teaching. The demonstration cabin 311 as the core containing structure is fixed on the top of the support block 2, to provide a relatively closed space for the whole sand table sliding installation and weather simulation. The observation window is set to facilitate students to observe the internal situation. The water pipe opening 3113 on the top thereof is used to be connected with the water storage tank 4111 in the weather simulation part 4, to realize the rainfall simulation function. The guide sliding rail 314 is installed on the outer wall of the bottom wall of the demonstration cabin 311, and the sliding block 315 slides in the guide sliding rail 314. This sliding structure enables the sand table box 318 installed on the top of the sliding block 315 to move stably in the demonstration cabin 311. The sand table net 319 in the sand table box 318 is used to place sand or other materials simulating terrain. The sealing plate 3111 on the outer wall thereof is matched with the rectangular port of the outer wall of the demonstration cabin 311, to ensure the sealing property of the demonstration cabin 311 when the sand table box 318 is in the working position. The drain valve pipe 317 is slidably connected with the drain pipe sliding groove 316 on the inner wall bottom of the demonstration cabin 311, to facilitate the drainage of excess water in the sand table box 318. The handle 3112 can be conveniently pulled to pull the sand table box 318, to realize the replacement or adjustment of the sand table. The ventilation box 411 is arranged on the outer wall on both sides of the demonstration cabin 311. The ventilation screen plate 415 in the ventilation box 411 is provided with the fan 416 and the fan 417. The fan 416 is fixed on the ventilation screen plate 415 through the fan fixing frame 414. After the fan 416 is started, the fan 417 rotates to generate airflow. The airflow enters through the installation circular port on the ventilation box 411, then enters the demonstration cabin 311 through the rectangular ventilation port on the fixed block 418 and the rectangular port 312 on both sides of the demonstration cabin 311, to simulate the flow of wind on different terrain sand tables. The sand inlet hopper 412 is connected on the top of the ventilation box 411. The sand inlet screen 413 in the sand inlet hopper 412 can prevent foreign matters from entering the ventilation system. When the airflow generated by ventilation passes through the sand inlet hopper 412, the sand in the sand hopper can be brought into the ventilation box 411, and then into the demonstration cabin 311 along with the airflow, to simulate the sand-dust weather phenomenon. The water storage tank 4111 can supplement water source through the water inlet pipe 4112. When rainfall simulation is needed, the water in the water storage tank 4111 enters the demonstration cabin 311 through the water outlet pipe 4113 and the water pipe opening 3113, and then is sprayed out from the rainfall spray head 4114 at the bottom of the communication block 4115, to simulate the rainfall process. The raindrops falling on the sand table can demonstrate the influence of precipitation on terrain and the effect of different terrain on precipitation distribution. The control box 419 is fixed on the top outer wall of the demonstration cabin 311, to control the rotating speed of the fan 416, the water spraying and non-spraying of the rainfall spray head 4114 and the water spraying intensity of the rainfall spray head 4114 and other weather simulation parameters, to realize the accurate control of the demonstration process, to meet the needs of different weather teaching scenes.
