Technical Field

[0002] Rainfall environment testing devices are used to simulate natural rainfall environments. They are mainly used in scientific research, product testing, and other fields. They can typically simulate artificial rainfall of different intensities, providing scientific basis for soil and water conservation, rainwater harvesting projects, and field experiments. In addition, rainfall environment testing devices are also used to simulate water spray and water droplet tests that electronic products and their components may be subjected to during transportation and use, in order to test the waterproof performance of the products. Rainfall environment testing devices have wide applications in many fields, providing important support and guarantee for scientific research and product development.

[0003] Existing experimental setups typically use directional spray plates to transmit water flow to simulate rainfall during experiments. However, due to the varying intensity and characteristics of natural rainfall, the use of directional spray plates may not be able to simulate the randomness and uniform spatial distribution of natural rainfall, leading to deviations between experimental results and actual conditions and affecting the accuracy of simulated rainfall.

[0004] Therefore, for the existing experimental devices mentioned above, due to the different intensities and characteristics of natural rainfall, the use of directional spray plates may not be able to simulate the randomness and uniform spatial distribution of natural rainfall, resulting in deviations between experimental results and actual conditions, affecting the accuracy of simulated rainfall. An experimental device that can simulate various rainfall environments can be designed to generate simulated rainfall of different raindrop sizes and distributions according to experimental needs, realizing the simulation of light rain to heavy rain, adapting to different research purposes and experimental conditions, and improving the flexibility and diversity of experiments.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The experimental frame 201 is located at the upper end of the support platform 1. The interior of the experimental frame 201 is provided with two sets of rotating cylinders 202. The outer wall of the rotating cylinders 202 is surrounded by multiple sets of through holes. One end of the two sets of rotating cylinders 202 is located on the outer wall of the experimental frame 201 and is equipped with a drive motor 203.

[0023] Please see Figures 1-2 In this embodiment, a connecting sleeve 206 is provided between the drive motor 203 and the experimental frame 201. A conveying pipe 204 is provided above the experimental frame 201, and a diversion pipe 205 is provided on the outer wall of the conveying pipe 204. The conveying pipe 204, the diversion pipe 205, and the connecting sleeve 206 are connected. By adjusting the flow rate of the conveying pipe 204 and the diversion pipe 205, the intensity of rainfall can be precisely controlled to simulate different levels of rainfall conditions, so that the water flow is evenly distributed inside the rotating cylinder 202, changing the size of the rainfall coverage to adapt to different experimental needs. The water storage tank 210 is located at the outer end of the support platform 1. A water pump is provided between the conveying pipe 204 and the water storage tank 210. By using the water pump to control the water flow inside the water storage tank 210 to pump out and transport, the speed and pressure of the water flow can be controlled to simulate different intensity rainfall environments, change the intensity and duration of rainfall, meet different experimental needs, and facilitate scientific research and data analysis.

[0024] Please see Figures 1-3 In this embodiment, the outer end of the rotating cylinder 202 is provided with two sets of heating rods 207. One end of each set of heating rods 207 is located on the outer wall of the experimental frame 201 and is provided with a transmission cable 208. By using the two sets of heating rods 207 to control the internal temperature of the experimental frame 201, the temperature uniformity inside the experimental frame 201 is achieved, avoiding local overheating or overcooling. According to different experimental requirements, the temperature setting of the heating rods 207 can be adjusted so that the device can work stably under different environmental conditions, ensuring the reliability of the experiment. The outer wall of the water tank 210 is provided with a control panel 211. The control panel 211 is electrically connected to the water pump and the transmission cable 208. By using the control panel 211 to control the water flow and heating conditions, automatic control is achieved, which facilitates the collection and analysis of experimental data, better simulates the natural environment, and improves the reliability of experimental results.

[0025] Please see Figures 2-4In this embodiment, the rear end of the experimental frame 201 is provided with a recycling pipe 212. The support platform 1 is connected to the water storage tank 210 through the recycling pipe 212. A self-priming pump is provided between the recycling pipe 212 and the support platform 1. By using the recycling pipe 212 to connect the support platform 1, the water flow can be recycled in time after the device receives rainfall, realizing the recycling of water resources, avoiding waste of water resources, and facilitating the management of the experimental device. The upper end of the support platform 1 is located inside the experimental frame 201 and is provided with a rain gauge 213. By using the rain gauge 213 to record the amount of water in a single rainfall, the rainfall situation can be monitored in real time, providing accurate rainfall data for subsequent analysis and research.

[0026] During the experiment, soil material for the experiment is first laid inside the experimental frame 201. The water pump is then started first, transferring water from the storage tank 210 to the rotating cylinder 202 via the delivery pipe 204 and the distribution pipe 205. Next, the drive motor 203 is started to rotate the two sets of rotating cylinders 202. The rotation speed and angle of the rotating cylinders 202 are adjusted according to experimental requirements to generate simulated rainfall of different raindrop sizes and distributions, simulating rainfall from light rain to heavy rain, adapting to different research objectives and experimental conditions. The water pump is used to adjust the flow rate of the delivery pipe 204 and the distribution pipe 205, evenly distributing the water inside the rotating cylinder 202. The size of the rainfall coverage is changed to simulate different levels of rainfall conditions. Two sets of heating rods 207 are connected to the control panel 211 to heat the internal temperature of the experimental rack 201, so as to achieve temperature uniformity inside the experimental rack 201 and avoid local overheating or overcooling. This allows the device to work stably under different environmental conditions. After a single time, the rainfall volume is recorded by the rain gauge 213 to monitor the rainfall in real time and provide accurate rainfall data for subsequent analysis and research. A self-priming pump connected to the recovery pipe 212 is used to recover the water flow inside the support plate 1, realizing the recycling of water resources and facilitating the management of the experimental device and secondary experiments.

[0027] Through the above steps, by using a drive motor 203 to drive two sets of rotating cylinders 202 to rotate, and adjusting the rotation speed and angle of the rotating cylinders 202 according to experimental needs, simulated rainfall of different raindrop sizes and distributions can be generated, realizing the simulation of light rain to heavy rain. Rainfall parameters can be quickly adjusted to adapt to different research objectives and experimental conditions, improving the flexibility and diversity of the experiment. Furthermore, by adjusting the flow rate of the delivery pipe 204 and the diversion pipe 205, the intensity of rainfall can be precisely controlled, simulating different levels of rainfall conditions, ensuring that the water flow is evenly distributed inside the rotating cylinders 202, changing the size of the rainfall coverage to adapt to different experimental needs. Two sets of heating rods 207 are used to control the internal temperature of the experimental frame 201, achieving temperature uniformity inside the experimental frame 201 and avoiding local overheating or undercooling. The temperature settings of the heating rods 207 can be adjusted according to different experimental needs, enabling the device to work stably under different environmental conditions and ensuring the reliability of the experiment.
