Embodiment 1

[0031] Example 1, such as figure 1 As shown, a runoff water sample collection device includes a sampling box 1 , a filtering and collecting device 2 inside the sampling box 1 , a water sample packing device 3 , a sampling bottle device and a driving device 6 .

[0032] The filtering and collecting device 2 is located on the top of the sampling box 1, and is used to filter the water flow and improve the sample quality. Specifically, the filter collection device 2 includes a first filter device 22 located on the uppermost floor and one side hinged to the sampling box 1, a second filter device 21 located in the middle, and a funnel-shaped confluence tank 23 located below the second filter device 21, The size of the filter holes of the second filter device 21 is smaller than that of the first filter device 22 .

[0033] The water sample dispensing device 3 comprises a rotary bin provided with an annular ring gear 35 at the bottom, a rotating support column 32 positioned at the bo...

Embodiment 2

[0037] Embodiment 2, on the basis of embodiment 1, as figure 2As shown, the first filter device 22 includes a first filter plate 223 and several cross-distributed vertical rods 222 above the first filter plate 223, and the second filter device 21 has a smaller aperture than the first filter plate 223. Pore ​​size of the second filter plate. The vertical rod 222 is arranged above the first filter plate 223, which can prevent the washed leaves from covering the filter plate below, causing most of the runoff to flow directly above the sampling device. As preferably, the active side of the first filter plate 223 shown (i.e. figure 2 The right side in) is also provided with handle 221.

Embodiment 3

[0038] Embodiment 3, in order to avoid that the water sample flowing out of the draft tube 33 cannot accurately enter the sampling bottle 45, on the basis of Embodiment 1 or Embodiment 2, the sampling bottle device described in this embodiment also includes a Rotating support beam 32 is fixedly socketed with a limit deflector 41. The top surface of the limit deflector 41 is provided with an annular limit groove 411 suitable for the circular movement of the flow guide tube 33, and the bottom surface is provided with an annular limit groove. 411 runs through and is opposite to a plurality of water outlet holes of the sampling bottle 45 bottlenecks below, the bottleneck of the sampling bottle 45 is screwed with the water outlet hole of the limiting deflector 41, and the limiting deflector 41 can be connected to the flow guide tube 33. The trajectory of the movement is accurately limited, and the water sample is accurately flowed into the sampling bottle 45 through the water outlet...

Abstract

The invention discloses a runoff water sample collecting device. The runoff water sample collecting device comprises a sampling tank, a filter collecting device located in the sampling tank, a water sample split-charging device, a sampling bottle device and a driving device; and the water sample split-charging device comprises a rotating bin driven by the driving device to rotate, a rotating supporting polished column located at the bottom of the rotating bin, and a flow guiding pipe connected with a water outlet in the bottom of the rotating bin, and the top of the rotating bin is rotatably connected with a bottom outlet of the filter collecting device. The sampling bottle device comprises a circular-ring-shaped supporting plate connected to the rotating supporting polished column in a sleeving mode, and a plurality of sampling bottles arranged on the fluid spraying circumference in the flow guiding pipe, and the sampling bottles are fixed to the circular-ring-shaped supporting plate.According to the runoff water sample collecting device, impurities can be filtered, the sample quality is higher, continuous sampling can be achieved through rotating of the rotating bin, manual collecting does not needed to be used, and sampling is more standard.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a runoff water sample collection device. Background technique [0002] For areas rich in rainwater and forest resources, the water quality of forest areas often deteriorates. Current research believes that the main factor is that the dissolved nutrients carried by trees are collected into surface runoff under the action of rainfall and enter the water bodies of forest areas to cause pollution. Different tree species Therefore, the research on surface runoff water samples is of great significance for the follow-up water pollution control. The existing sampling devices mainly use sampling bottles for collection, and the sampling and transportation rely heavily on manual labor, and the standardization of sampling and sample quality There are also certain problems. Contents of the invention [0003] In order to solve the technical problems in the prior art that sam...
