[0033] In use, first, connect one of the turnover frames 111 with the external motor, then open the main body 1 and place the plurality of sampling bottles in the main body 1, and sequentially insert the plurality of hoses 122 into the sampling bottles, then tighten the cover to tightly seal the hoses 122 with the sampling bottles, then when it rains, the rainwater will fall on the surface of the precipitation sensor 101, at this time, when the precipitation sensor 101 senses the rainwater, it will control the turnover frame 111 connected thereto to rotate, when the turnover frame 111 rotates, it will drive the closing cover 112 to rotate, at this time, the closing cover 112 will separate from the inlet pipe when the closing cover 112 rotates with the turnover frame 111, at this time, the falling rainwater will flow into the central disc 121 through the inlet pipe and flow into the sampling bottles through the cylindrical groove and the hose 122, when the sampling bottles are separated from the hose 122, the sampling work is completed.

[0034] When the turnover frame 111 drives the closing cover 112 to separate from the water inlet pipe, the turnover rod 132 will not be pressed by the closing cover 112, at this time the spring of the spring disc on the sliding shaft 213 will contract under the action of its own elastic potential energy and make the sliding shaft 213 slide upwards, when the sliding shaft 213 slides upwards, it will make the cladding frame 221 and the disc 222 extend out of the top of the water inlet pipe, at this time the disc 222 will be in the upper area of the water inlet pipe, then when it rains and produces a strong wind, the flow direction of the strong wind will act on one side of the disc 222, at this time the disc 222 will rotate on the top of the sliding shaft 213 through the cladding frame 221 under the oblique flow of the strong wind, at this time the disc 222 will be in an inclined state in the area of the top of the water inlet pipe, and form an inclined baffle on the top of the water inlet pipe, through the baffle formed after the disc 222 is inclined, the trajectory of the inclined raindrops can be blocked, and the raindrops can be guided to enter the sampling pipe more smoothly along the inclined surface of the disc 222, reduce the situation that part of the raindrops are blown out of the range of the water inlet pipe due to the falling trajectory deviation of the raindrops under the touch of the strong wind when falling, reduce the situation that the sample amount entering the device during precipitation is less than the rainfall amount, and improve the stability of precipitation sampling and the accuracy of actual sampling amount.

[0035] When the strong wind blows to the surface of the disc 222 in an inclined path, the inclination of the disc 222 will make the limiting spring of the disc 222 at the raised position in a stretched state, when the wind is not in an inclined flow or disappears, the disc 222 will reset under the action of the limiting spring and be in a horizontal state, when the sliding shaft 213 slides upward under the elastic potential energy of the spring disc, the sliding of the sliding shaft 213 will drive the connecting plate 301 to slide upward through the spring disc, when the connecting plate 301 slides upward, it will drive the fixed ring 311 to move upward synchronously through the cross plate and the two curved springs, when the fixed ring 311 moves upward, it will contact with the side wall of the two fixed rods 212, because the two fixed rods 212 are arranged in a stepped manner, when the connecting plate 301 drives the fixed ring 311 to contact with the fixed rod 212, the fixed ring 311 and the internal semicircular plate 322, the connecting ring 321 will be blocked by the two fixed rods 212 to rotate when inclined, at this time the flexible layer 313 will rotate from the bottom area of the water inlet of the main body 1 to an inclined state, at the same time, the upward movement of the fixed ring 311 will drive the plurality of floating discs 324 to move synchronously, at this time the outer surface of the floating disc 324 will have a gap with the cylindrical groove, then when the motor 201 drives the connecting shaft 211 to rotate, the rotation of the connecting shaft 211 will drive the inclined fixed ring 311 and the connecting ring 321 to rotate synchronously, when the fixed ring 311 rotates after being inclined, the rainwater falling through the water inlet pipe under the guidance of the disc 222 will flow onto the flexible layer 313 in the fixed ring 311, at this time the rotation and inclination of the fixed ring 311 after the rainwater will guide the falling rainwater to evenly flow into the plurality of cylindrical grooves on the central disc 121, by guiding the uniform flow of rainwater, it can reduce the situation that the falling rainwater is blocked by the inclination of the disc 222, causing the rainwater to fall on the central disc 121 to appear the situation that part of the cylindrical grooves is subjected to the flow of rainwater while the other part of the cylindrical grooves cannot receive rainwater, affecting the uniform distribution of the sample amount for subsequent sampling, at the same time, when one of the cylindrical grooves and the corresponding water source in the sampling bottle is full, at this time the fixed ring 311 will push the corresponding floating disc 324 to move downward in the cylindrical groove when rotating, because the floating disc 324 will not move downward under the action of water buoyancy after the cylindrical groove is full of water, at this time the fixed ring 311 rotating in the position of the cylindrical groove full of water can reduce the overflow of precipitation between the cylindrical grooves, improve the uniform distribution of precipitation, at the same time, reduce the mixing pollution between the water sources in the sampling bottles and the cylindrical grooves caused by overflow, improve the uniform distribution of rainwater in the sampling bottles, and improve the accuracy of subsequent detection and analysis.

[0036] When the fixed ring 311 moves up and contacts the fixed rod 212, the upward movement of the fixed ring 311 will cause the fixed ring 311 to tilt, and at the same time, the connecting ring 321 will be blocked by the fixed rod 212 and slide downward. When the connecting ring 321 slides downward, the sliding of the connecting ring 321 will push the two semicircular plates 322 to rotate relatively inside the fixed ring 311. When the two semicircular plates 322 rotate under the push of the connecting ring 321, the two semicircular plates 322 will form a concave area in the fixed ring 311 under the blockage of the inclined plate 312. When the rainwater falling through the water inlet pipe falls into the inside of the fixed ring 311, the falling rainwater will accumulate and flow in the concave area formed by the flexible layer 313. Since the flexible layer 313 forms a concave area in the fixed ring 311, the downward flow of the rainwater can block the splashing part of the rainwater when it falls into the concave area, thereby reducing the situation that the rainwater splashes when it falls due to the excessive speed of the rainwater flow, and further enhancing the uniformity of the distribution of the falling rainwater, thereby enhancing the sampling efficiency.

[0037] When the disc 222 is not blown by the strong wind after being tilted, the disc 222 will reset under the elasticity of the bottom limiting spring, and the top of the water inlet pipe will be in a horizontal state. Then, when the rainwater accumulates and falls, part of the rainwater will accumulate in the water storage disc 232. When the water storage disc 232 is full of rainwater, the water storage disc 232 will slide downward under the weight of the accumulated rainwater inside. When the water storage disc 232 slides downward, it will push the middle rod downward through the hollow rod 231. At this time, the middle rod will change from a horizontal state to an inclined state under the push of the hollow rod 231. At this time, the arc-shaped plate 233 connected to the middle rod will rotate inward. At this time, there will be a gap between the disc 222 and the water inlet pipe. When the external precipitation stops, the water inside the water storage disc 232 will slowly flow outward through the tapered hole. At this time, as the water flows outward, the water storage disc 232 will slide upward under the elastic force of the auxiliary spring at the bottom. At this time, the multiple arc-shaped plates 233 will rotate outward and block between the disc 222 and the water inlet pipe, reducing the entry of external impurities or dust. Through the blockage of the multiple arc-shaped plates 233, it can reduce the situation that when the precipitation stops, the central disc 121 does not close with the water inlet pipe due to the presence of rainwater on the precipitation sensor 101, thereby causing external dust or other impurities to enter the device through the water inlet pipe, affecting the purity of the sampling sample. At the same time, it improves the purity of the sample, reduces the residue and adhesion of dust in the device, and affects the next sampling situation, improves the neatness and quality of the sampling.
