Description

Technical Field

[0001] The invention relates to a rainwater sampling device and belongs to the field of meteorological research. Background Art

[0002] Accurately collecting and analyzing rainwater samples is crucial for environmental monitoring, meteorological research, and ecological studies. However, traditional rainwater collection systems have numerous shortcomings and are often not integrated with advanced technologies like the internet. Their functionality is limited to simple collection after rainfall.

[0003] On the one hand, these systems do not fully consider the impact of rainfall intensity on the collection process. In the early stages of rainfall, if the rainfall is small and does not meet the predetermined collection standards, the system cannot discharge this part of rainwater in time, but continues to collect it, causing the collection process to last for more than a day. This makes the measured rainwater data lack real-time performance and cannot provide timely and accurate data support for related research. On the other hand, the existing systems lack precise control over rainwater collection conditions, making it difficult to set reasonable collection start and end conditions according to actual research needs, and cannot guarantee that the collected rainwater samples are representative. At the same time, there is currently a lack of integrated rainwater sampling devices that can take into account real-time monitoring of rainfall, precise control of the collection process, and convenient operation and maintenance. This has to some extent restricted research progress in related fields. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rainwater sampling device with a high degree of automation, timely and accurate collection, and convenient operation.

[0005] In order to solve the above technical problems, the rainwater sampling device of the present invention includes a box with a control module and a rainwater sampling equipment group arranged in the box; the box is provided with a rainwater collection port that can be opened or closed, and the rainwater collection port is connected to the rainwater sampling equipment group.

[0006] The rainwater sampling equipment group includes a sampling barrel connected to the rainwater collection port through a rainwater inlet pipe and a plurality of sampling bottles connected to the sampling barrel through a sampling pipe. A rainwater discharge pipe connected to the outside of the box is provided at the bottom of the sampling barrel.

[0007] The control module includes a rain gauge arranged on the box for collecting rainfall data, a control panel for interaction, and electromagnetic valves respectively arranged on the rain inlet pipeline, the sampling pipeline and the rain discharge pipeline.

[0008] The box body is provided with a cabinet door, and the control panel is installed on the cabinet door.

[0009] A shielding cover is hinged on the rainwater collection port, and a driving device for controlling the opening and closing of the shielding cover is provided on the box body.

[0010] The driving device is a cylinder.

[0011] The box body is made of stainless steel.

[0012] The advantages of the present invention are: real-time monitoring of rainfall through a rain gauge, and automatic control of the opening and closing of each solenoid valve according to preset conditions with the help of a control panel, thereby achieving accurate collection of rainwater, avoiding human errors, and convenient operation and high efficiency; users can intuitively understand current data and the conditions of each component in the device through the control panel, which is convenient for maintenance and has strong flexibility; the box body is made of corrosion-resistant and UV-resistant stainless steel, which can effectively protect internal components and adapt to various harsh outdoor environments, thereby increasing service life and enabling the device to operate stably for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 A perspective view of the present invention; Figure 2 It is the front view of the present invention. DETAILED DESCRIPTION

[0014] The rainwater sampling device of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] As shown in the figure, the rainwater sampling device of the present invention includes a stainless steel box 12, on which is provided a cabinet door 10, and a control panel 11 as part of the control module is installed on the cabinet door 10. A rain gauge 1 as another part of the control module is provided above the box 12. Because it is set in an open area outside the box 12, the rain gauge 1 can receive rainwater without obstruction. It is equipped with a high-precision rain sensor component inside, which can accurately measure rainfall and transmit data to the control panel 11, providing key rainfall data support for the entire rainwater sampling device. The control panel 11 is provided with a display screen and provides interactive support. The user can intuitively understand the current rainfall, system settings and status, and other information in real time, and set the starting threshold and termination conditions for the automatic collection and sampling of rainwater.

[0016] A rainwater collection port 4 is provided on the box body 12, and a shielding cover 3 is hinged on the side of the rainwater collection port 4. A driving device 2 is provided on the box body 12 at the hinge of the shielding cover 3. In this embodiment, it is a cylinder. The top end of the telescopic rod of the cylinder is connected to the shielding cover 3 through a mechanical connector, so as to realize the control of its opening or closing.

[0017] A rainwater sampling equipment group is provided inside the box 12, including a sampling barrel 6, a sampling bottle 8 and multiple connecting pipes. The sampling barrel 6 is installed in the box 12 through a bracket. A rainwater inlet pipe 5 connected to the rainwater collection port 4 is provided above it, and a rainwater discharge pipe 7 extending to the outside of the box 12 is provided on the bottom. The bottom side is connected to the sampling bottle 8 through a sampling pipe 9. There are multiple sampling bottles 8 arranged side by side, so the sampling pipe 9 also branches out from the main pipe into multiple branch pipes, which are respectively connected to each sampling bottle 8.

[0018] The control module also includes solenoid valves, one each installed on the rainwater inlet pipe 5, the other on the sampling pipe 9, and the other on the rainwater discharge pipe 7. Each solenoid valve is used to control the inflow and outflow of rainwater at various locations. When the collection conditions are met, the rainwater inlet pipe solenoid valve opens, and rainwater flows from the rainwater collection port 4 into the sampling barrel 6 for temporary storage. When the sampling conditions are met, the sampling pipe solenoid valve opens, and rainwater flows from the sampling barrel 6 into the sampling bottle 8, completing the sampling process. When the rainfall does not meet the set standard or the sampling barrel 6 needs to be emptied after sampling, the rainwater discharge pipe solenoid valve opens, and rainwater is discharged from the sampling barrel 6 to the outside of the box 12.

[0019] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
