[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1 and Figure 2 As shown, an adjustable rainfall intensity quantitative simulation rainfall device includes a main container 3 with graduations, a three-way valve 4 for controlling water output, a quick-connect fitting 8, and a detachable nozzle 9. To ensure that the specific solution volume inside the container and the drop in liquid level during rainfall can be observed, the main container 3 and the soft and hard water pipes 5 are connected by a flexible hose 7 that is completely transparent.

[0019] The graduated main container 3 has a maximum volume of 3200 ml. A three-way valve 4 is installed at the apex of the conical bottom of the container to control the water outlet. It connects to flexible and rigid water pipes 5, flexible and rigid pipe connectors 6, connecting hoses 7, and quick-connect fittings 8 to guide water to the sprinkler head 9 to control rainfall. A removable top cover 2 is provided on the top of the main container for easy solution replenishment. An inlet 1 is also provided for continuous and stable solution replenishment, enabling qualitative continuous rainfall simulation. An adjustable support frame 10 is provided outside the main container 3 to ensure sufficient space below the device to place the container bottle under the sprinkler head. An internal diagram of the three-way valve 4 is shown below. Figure 4 As shown.

[0020] The graduated main container 1 and the connecting flexible and rigid water pipes 5 are both made of transparent acrylic plastic sheets. The main container is a cylindrical-conical composite, and the flexible pipes are also transparent to facilitate observation of the solution flow. The main container 3 has a radius of 10 cm and a total height of 16 cm (8 cm for the cylindrical part and 8 cm for the conical part). The connecting flexible and rigid water pipes 5 have a diameter (inner diameter) of 2 cm (with threads on the inner wall), a length of 4 cm, and are connected to the flexible pipe 7 using a 2-point water purifier PE pipe quick-connect interface, i.e., a flexible and rigid pipe connector 6 (with threads on the outer diameter), with an outer diameter (thread) of 20 mm. The flexible pipe 7 (2 cm in length) is connected to the nozzle 9 via a quick-connect plug 8, where the nozzle 9 can be detached from the quick-connect plug 8 to ensure that the solution can flow smoothly from the nozzle 9.

[0021] The three-way valve 4 is connected to the bottom of the main container 3. By rotating the three-way valve, the liquid in the main container 3 can be controlled to enter the connecting soft and hard water pipe 5, which is 4 cm long.

[0022] The nozzle 9 is made of metal and can be rotated to adjust the atomization size to control the rainfall intensity; at the same time, the water discharge can be stopped in time by rotating the water outlet switch. This allows for the simulation of different rainfall intensities in the laboratory.

[0023] The detachable top cover 2 is threaded to facilitate solution replenishment, and the inlet 1 provides a continuous and stable solution supply for qualitative continuous precipitation simulation. It also prevents excessive solution in the container from breaking the device and damaging it, thus improving the operational fault tolerance rate.

[0024] like Figure 3 As shown, the retractable support bracket 10 consists of an adjustable support frame and a ring structure with an inner diameter equal to the outer diameter of the main container (20 cm), allowing the main container to be stably placed on the support structure and also removed from it. Three support frames 10 are provided, with a central angle of 120° between the arcs of every two support frames 10. The retractable function is achieved using a snap-fit ​​structure, with a minimum length of 30 cm and a maximum length of 45 cm. Each support frame forms an angle of 85° with the horizontal ground. The top of each support frame connects to the support ring, forming the retractable support bracket 10. This design improves the flexibility of the device. The lower 15 cm of each support frame is solid, while the upper 15 cm contains a retractable section, with a snap-fit ​​structure at the junction of the two retractable sections. The flow meter 11 can measure the instantaneous water flow through the water pipe in real time and display the total flow rate within a time period on the digital display screen.

[0025] The material dimensions of the device are shown in Table 1: Table 1

[0026] Working principle: 1) Open the removable top cover 2, fill the graduated main container 3 with a certain amount of solution, and close the three-way valve 4 before filling the solution. After adding a certain amount of solution, put the threaded removable top cover 2 on. 2) Place the culture bottle that needs rainfall vertically under the nozzle 9, open the three-way valve 4 to allow the solution to pass through the connecting soft and hard water pipe 5, the soft and hard pipe connector 6, the connecting hose 7 and the quick-connect plug 8 to the nozzle 9 to simulate rainfall. During this process, the rainfall intensity can be changed by adjusting the nozzle 9.

[0027] 3) The maximum simulated rainfall of this device is 3200 ml. During the process, the three-way valve 4 can be closed and the nozzle 9 can be adjusted to stop the water flow by observing the water level scale line 3 in the main tank, so as to change the rainfall target and realize the simulation of rainfall of multiple bottles of samples in one time.

[0028] 4) When using this device to simulate rainfall, the flow meter 11 monitors the instantaneous flow rate passing through the flow meter in real time and records the total flow rate passing through the flow meter in a single flow, thereby achieving quantitative rainfall and reducing experimental errors.

[0029] The main body of the graduated container 3, consisting of a cylindrical and conical water tank, features graduations. A three-way valve controls the inflow and outflow of solution, which is directly connected to the nozzle via a hard water pipe, a hard / soft water pipe converter, a soft water pipe, and a quick-connect fitting. A container for receiving rainfall is placed below the nozzle. An adjustable support structure surrounds the main body, ensuring sufficient space for the container under the nozzle. This invention solves the problem of quantitatively simulating extreme rainfall in indoor cultivation experiments without damaging the soil structure or its original physicochemical properties. The rainfall intensity can be adjusted by changing the atomization of the nozzle. The adjustable support structure allows for flexible height adjustment based on the actual object height. Furthermore, the main container is not fixed to the support structure and can be removed for rainfall simulation when necessary, improving the device's practicality. The addition of a flow meter to the graduated system enables highly accurate quantitative rainfall simulation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
