[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0017] like Figure 1 As shown, a preferred embodiment of this utility model provides an atmospheric dry and wet deposition collection device, comprising:
[0018] The receiving cylinder 1 is hollow inside and open at the top, used to receive atmospheric dry and wet sedimentation. A filter screen 2 is laid on the top of the receiving cylinder 1. A waste liquid discharge port is provided at the bottom of the receiving cylinder 1, and a liquid intake port is provided at the lower part of the receiving cylinder 1.
[0019] Water quality parameter sensor 5 is installed inside the receiving cylinder 1;
[0020] The water level sensor 6 is installed inside the receiving cylinder 1.
[0021] In the above technical solution, the device is placed on a rooftop or other high location. Atmospheric dry and wet deposition passes through filter 2 into the cylinder. After the filter intercepts impurities such as leaves, the liquid flows into the cylinder. Water quality sensor 5 is used to monitor atmospheric dry and wet deposition parameters, and water level sensor 6 is used to monitor the atmospheric dry and wet deposition water level. Overall, it can realize automatic collection and monitoring of atmospheric dry and wet deposition.
[0022] In another technical solution, both the water quality parameter sensor 5 and the water level sensor 6 are connected to the PLC controller 4, and the PLC controller 4 can control the start and stop of the water quality parameter sensor 5 and the water level sensor 6.
[0023] In another technical solution, the battery 7 supplies power to the PLC controller 4, and the battery 7 is connected to the solar panel 8. The solar panel 8 continuously charges the battery 7.
[0024] In another technical solution, the waste liquid discharge port is connected to the waste liquid tank via a waste liquid discharge pipe 9, and a waste liquid drain valve 12 is installed on the waste liquid discharge pipe 9. The liquid intake port is connected to the outside via a liquid intake pipe 10, and a liquid intake control valve 11 is installed on the liquid intake pipe 10.
[0025] When collecting atmospheric dry and wet deposition, open the liquid collection control valve 11 and collect it from the liquid collection port at the end of the liquid collection pipe 10. After the atmospheric dry and wet deposition is collected, open the waste liquid drain valve 12 and discharge the excess atmospheric dry and wet deposition through the waste liquid discharge port at the end of the waste liquid discharge pipe 9.
[0026] In another technical solution, the surface of the filter screen 2 is recessed downward to form a receiving groove, and a coarse sand layer and a fine sand layer are arranged sequentially from top to bottom in the receiving groove to improve the filtration effect and prevent the residue from entering the receiving cylinder 1 through the filter screen.
[0027] In another technical solution, an annular flow guide groove is provided around the top periphery of the receiving cylinder 1. The cross-section of the flow guide groove is U-shaped, and multiple flow guide holes are provided at the bottom of the groove to quickly collect rainwater or sediment into the flow guide holes. The bottom of the flow guide groove is inclined towards the center of the receiving cylinder at an angle of 8°-12°, and the flow guide holes are located at the lowest point of the groove bottom, so that the liquid converges along the inclined surface and enters the filter screen through the flow guide holes. Furthermore, the inner wall of the flow guide groove is coated with a hydrophobic nano-coating with a coating thickness of 50-100μm to reduce liquid residue and accelerate flow.
