Description

Technical Field

[0001] This invention relates to the field of weather simulation technology, specifically to a simulation experimental system based on sandstorm weather conditions. Background Technology

[0002] Dust storms are weather phenomena in which strong winds lift large amounts of dust and sand from the ground, making the air turbid and significantly reducing horizontal visibility. Generally speaking, dust storms are storms that carry large amounts of dust and sand and mostly occur in desert or semi-arid regions. my country has a large number of desert areas, so it is necessary to test various materials before carrying out some infrastructure projects. Therefore, experimental equipment that simulates dust storms is needed to assist in the testing and better support the infrastructure construction.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0022] 1. A sand and dust simulation component is installed. Simulated sand is loaded into a sand-flowing funnel, flows through a return pipe to the inside of the auger, and then flows through a discharge pipe to the top of the distribution cone. The sand is blocked by a baffle plate and falls into the inside of the discharge chute. After the sand falls back, it is blown by a blower into the experimental material inside the experimental chamber, thus simulating a sandstorm. The falling sand then falls back into the sand-flowing funnel, and the cycle repeats to form the next sandstorm simulation. This allows for continuous and stable sandstorm simulation, ensuring that the experimental material remains stably exposed to sandstorm conditions for an extended period. This provides real and effective experimental data, which can help improve the experimental material and facilitate the country's development in desert areas, thereby promoting local economic and cultural development and improving the quality of life.

[0023] 2. An observation component is provided. The sliding tube is moved to the inner position of the experimental chamber, and then the limiting screw is tightened to fix the sliding tube. At this time, the photographic device on the equipment clamp can be used to photograph the substance being tested, facilitating continuous observation of the substance's state. This prevents damage to the experimental substance in the event of significant damage, ensuring maximum and effective experimental data output, further improving the rigor of the experiment, and allowing for observation of the substance's lifespan. After multiple experiments, the fixing plate can be removed by twisting the plate, allowing replacement of the observation glass worn by sand and dust, thus ensuring the clarity of the observation.

[0024] 3. Equipped with a pressure relief component, the blower generates a large amount of air pressure during the experiment. This air pressure is discharged outward from the pressure relief slot, and the dust is collected at the pressure relief funnel. The dust then flows towards the air outlet duct, where the sand is filtered by the filter chip. The sand then flows back through the pressure relief funnel to the quicksand funnel to continue participating in the sand and dust experiment. Excess air pressure flows out of the air guide hole into the air, preventing it from flowing back into the experimental chamber and dispersing the quicksand. This prevents air pressure from disturbing the experimental environment and further ensures the accuracy of the experimental data. Attached Figure Description

[0047] The back of the experimental chamber 1 is provided with a pressure relief groove 401. There are two pressure relief grooves 401, which are symmetrically arranged on the back end face of the experimental chamber 1 for convenient and rapid pressure relief. A pressure relief funnel 402 is installed on the back of the experimental chamber 1 at the position corresponding to the pressure relief groove 401.

Several filter chips 406 are snapped at the outer position of the positioning rod 405 at equal intervals through the snap-fit ​​hole, which helps to prevent sand splashing.

[0048] The working principle and usage process of this invention are as follows: First, the material to be tested in the sandstorm experiment can be placed inside the experimental chamber 1, and simulated sand can be loaded into the sand-flowing funnel 201. When the solenoid valve 203 is opened, the sand inside the sand-flowing funnel 201 will flow, thus simulating the quicksand environment of a desert region. Items intended for use in quicksand environments can be placed in the sand-flowing funnel 201 to test their performance. The flowing sand will then flow through the return pipe 202 to the inside of the auger cylinder 204. Simultaneously, the auger motor 208 inside the motor slot 207 is opened, causing the auger blades 206 to rotate. The auger blades 206 will then transport the sand inside the auger cylinder 204 upwards. When this sand reaches the discharge pipe 209, it will flow through the discharge pipe 209 to the top of the distribution cone 211, and then into the distribution cone 211. The sand flows to both sides of the 11, and then flows to the inside of the equalization hole 212. The sand then flows through the equalization hole 212 to the baffle plate 213. The flowing sand is blocked by the baffle plate 213 and falls to the inside of the discharge trough 214. After the sand falls back, it is blown by the blower 215, which blows the sand towards the experimental material inside the experimental chamber 1, thus simulating a sandstorm. The falling sand then falls back to the inside of the sand funnel 201, and then the cycle repeats to form the next sandstorm simulation. This allows for continuous and stable sandstorm simulation, so that the experimental material can be kept in a stable sandstorm environment for a long time to obtain real and effective experimental data. This can help people improve the experimental material, help the country to build in desert areas more smoothly, increase local economic and cultural development, and improve the quality of life.

[0049] Next, during the experiment, the camera is clamped in the device clamp 315. The monitoring device is then placed inside the sliding tube 302. The support rod 312 is rotated inside the rotating slot plate 311 to reach the bottom of the connecting rod 314, where the moving wheel 313 provides support. The connecting rod 314 is then pushed inwards, pushing the device clamp 315 holding the camera to the inside of the sliding tube 302. The handle 310 is then used to push the sliding tube 302 inside the fixed tube 301, moving it to the inside of the experimental chamber 1. Then, the limiting screw 309 can be tightened to fix the sliding tube 302. At this time, the photographing device on the equipment clamp 315 can be used to photograph the material being tested, so as to facilitate the observation of the state of the experimental material at any time. This prevents damage to the experimental material after major damage to the experimental material, thus ensuring that the experimental material can output reasonable and effective experimental data to the maximum extent, further improving the rigor of the experiment, and also allowing the observation of the lifespan of the experimental material. After multiple experiments, the fixing plate 304 can be removed by twisting plate 306, so that the observation glass 305 worn by sand and dust can be replaced, thus ensuring the clarity of the observation.

[0050] Finally, during the experiment, the blower 215 generates a large amount of wind pressure, which is discharged outward from the pressure relief groove 401. This wind dust is collected at the pressure relief funnel 402, and then flows to the air outlet 403. The sand in this wind dust is filtered by the filter chip 406. At this time, the sand flows back to the sand funnel 201 through the pressure relief funnel 402 to continue participating in the sand and dust experiment. Then, the excess wind pressure flows into the air through the air guide hole 407 to prevent this wind pressure from returning to the inside of the experimental chamber 1 and blowing away the sand, thereby preventing the wind pressure from disturbing the experimental environment and further ensuring the accuracy of the experimental data.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
