[0002] At present, in some industries, transportation, geology and other fields, it is necessary to use designed artificial rainfall simulation devices to simulate natural rainfall in order to study the rain resistance and rain removal capabilities of various research objects under different rainfall conditions. If the simulated rainfall is not realistic, the test will not achieve the expected results.

[0003] Rainfall simulation experiments are often used in environmental monitoring and management. Rainfall simulation experiments require the simulation of different rainfall amounts. When simulating different rainfall amounts, it is generally done by lowering the water pressure. The water nozzles of the simulation device cannot be adjusted or the adjustment is complex. The range of simulating different rainfall amounts by adjusting the water pressure is narrow. When the rainfall adjustment range is large, the experiment cannot be completed.

[0004] In the prior art, most simulation rainfall equipment cannot be used to observe the inside of the simulation device intuitively during use, so simulation experiments cannot be conducted accurately. In addition, most simulation devices in the prior art cannot conveniently adjust the position and height of the sprinkler nozzles, and cannot adjust the rainfall intensity as needed during use, so simulation rainfall experiments cannot be conducted accurately. For this reason, we propose a rainfall simulation experiment device to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Among them, the collecting component 1 includes a frame 11, a glass plate 12, a water collecting pipe 15 and an earth slope 16. The glass plate 12 is arranged on the frame 11, the earth slope 16 is arranged inside the frame 11, the water collecting pipe 15 is arranged on the earth slope 16, and a drainage board 14 is opened on the glass plate 12, and the drainage board 14 runs through the water collecting pipe 15.

[0031] Specifically, when conducting a simulated rainfall experiment, the device can be set up first. When conducting the experiment, the horizontal position and height of the rainfall component 4 can be adjusted in advance according to the needs of the experiment, and when in use, the size of the drop nozzle 46 and the mist nozzle 47 can also be adjusted (usually there are buttons or knobs for adjusting the spray range on the drop nozzle 46 and the mist nozzle 47, and the spray range size can be adjusted by rotating the buttons or knobs as needed). When adjusting the horizontal position and height of the rainfall component 4, it can be adjusted through the moving component 2 and the lifting component 3, so that the rainfall component 4 can be adjusted in position more quickly and conveniently.

[0032] Furthermore, when conducting a simulated rainfall experiment, rainwater can be collected by the collection component 1, and the experiment can be observed by the collection component 1.

[0033] In this embodiment, a handle 13 is provided on the frame 11 .

[0034] Specifically, in order to facilitate the position adjustment of the collecting component 1, a handle 13 is provided on the frame 11, through which the experimenter can better move the collecting component 1, thereby facilitating the position adjustment of the collecting component 1 before and after subsequent experiments.

[0035] In this embodiment, the moving component 2 includes a fixed seat 21, an A screw rod 23 and an A moving block 24. The fixed seat 21 is provided with an A slot 22, the A screw rod 23 is arranged in the A slot 22, the A moving block 24 is arranged on the A screw rod 23, and the A moving block 24 is arranged in the A slot 22.

[0036] Specifically, when conducting an experiment, if it is necessary to adjust the horizontal position of the rainfall component 4, it can be achieved by running the moving component 2. In specific use, it can be achieved by rotating the A screw rod 23. Since the A moving block 24 is threaded on the A screw rod 23, and the A moving block 24 is arranged inside the A slot 22, when the A screw rod 23 is rotated, the A moving block 24 can be driven to move. Since the lifting component 3 is arranged on the moving component 2, and the rainfall component 4 is arranged on the lifting component 3, when the A moving block 24 moves, the lifting component 3 can be driven to move, thereby driving the rainfall component 4 to move to a horizontal position.

[0037] In this embodiment, the lifting assembly 3 includes a lifting seat 31, a B screw rod 33 and a B moving block 34. The lifting seat 31 is arranged on the A moving block 24. A B slot 32 is opened on the lifting seat 31. The B screw rod 33 is arranged in the B slot 32. The B moving block 34 is arranged on the B screw rod 33. The B moving block 34 is arranged in the B slot 32.

[0038] Specifically, when the height of the rainfall component 4 needs to be adjusted during the experiment, the lifting component 3 can be operated to drive the rainfall component 4 to adjust its height. During specific use, since the rainfall component 4 is arranged on the B moving block 34, and the B moving block 34 is threaded on the B screw rod 33, and the B moving block 34 is arranged in the B slot 32, when the B screw rod 33 is rotated, the B moving block 34 will be driven to adjust its height, thereby driving the rainfall component 4 to adjust its height.

[0039] In this embodiment, the rainfall component 4 includes a connecting pipe 41, a transfer pipe 42, an A rainfall pipe 43 and a B rainfall pipe 44. The connecting pipe 41 is arranged on the B moving block 34, the B slot 32 is arranged on the lifting seat 31, and the A rainfall pipe 43 and the B rainfall pipe 44 are both arranged on the transfer pipe 42; the rainfall component 4 also includes a droplet nozzle 46 and a mist nozzle 47, and the droplet nozzle 46 and the mist nozzle 47 are respectively arranged on the A rainfall pipe 43 and the B rainfall pipe 44.

[0040] Specifically, when conducting a rainfall simulation experiment, the experiment can be carried out by setting up a connecting pipe 41, a transfer pipe 42 and four A rainfall pipes 43. During the experiment, water can be first injected into the connecting pipe 41, and then the injected water will flow into the transfer pipe 42, the A rainfall pipe 43 and the B rainfall pipe 44, and will be sprayed into the collection component 1 through the drop nozzle 46 or the mist nozzle 47 respectively, thereby completing the rainfall simulation experiment. In specific use, in order to be able to perform multi-scene simulation, the drop nozzle 46 and the mist nozzle 47 are separately set, and the two are respectively set on two A rainfall pipes 43, and are staggered.

[0041] In this embodiment, a water injection hole 45 is formed on the connecting pipe 41 .

[0042] Specifically, during actual use, in order to be able to inject water into the connecting pipe 41, a water injection hole 45 is opened on the connecting pipe 41. During use, a water pipe can be set in the water injection hole 45, and the water pipe can be connected to a water pump. The water pump can continuously inject water into the connecting pipe 41. In order to enable the experimenter to control more conveniently, a valve can be set on the water pipe to control the entry of water flow.

[0043] Furthermore, the frame 11 is set as a model box of 0.8*1*1m, the three sides of the model box are sealed by glass plates 12, the bottom is composed of steel plates, and holes are opened to prevent rainfall seepage from accumulating at the bottom. The bottom of the earth slope 16 is cut off by a large aperture 1 / 4 of the side, and the white water pipes sealed at both ends form a collection of slope runoff. The water stored in it is then sucked out by a small plastic water pipe through controlled pressure to weigh the slope rainfall runoff.

[0044] Furthermore, in actual use, in order to record the experimental data more accurately, a flow meter can be provided at the water injection port 45, and the water injection volume can be measured more accurately by the flow meter.

[0045] Furthermore, in actual use, the size of rainfall can be controlled by setting an external valve, and by adjusting the opening of the valve, the amount of water sprayed by the drop nozzle 46 and the mist nozzle 47 can be controlled, thereby controlling the rainfall intensity.

[0046] In this embodiment, according to Figure 6 As shown, during specific use, the device can be set at the upper end of the lifting component 5, so that the overall height of the device can be adjusted through the lifting component 5, and then the height and tilt angle of the device can be adjusted during use to complete rainfall simulation experiments with different needs.

[0047] Furthermore, in the present embodiment, the drain board 14 is a piece of glass of about 30 cm, rather than a whole piece of glass. Therefore, in actual use, it is not necessary to provide slots in the drain board 14 to drain rainwater inside the device.

[0048] Furthermore, in order to prevent the collected rainwater from containing debris during actual use, a filter may be provided inside the collection component to filter out the debris.

[0049] The working principle and use process of the utility model: when conducting a rainfall simulation experiment, the device can be set up in a standardized manner. After the setting is completed, the horizontal position and height position of the rainfall component 4 can be adjusted according to different experimental requirements, so that the rainfall component 4 can conduct multi-scenario simulation experiments, and during the experiment, the rainfall intensity and range can be adjusted by the rainfall component 4, so that the use scenario of the present device is further expanded, and in specific use, in order to be able to discharge the rainwater inside the collection component 1 in time, a water collection pipe 15 is opened on the collection component 1, and during use, the drain pipe can be inserted into the water collection pipe 15, and the drain pipe can be connected to the water pump, thereby improving the drainage efficiency.

[0050] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
