Embodiment 1

[0027] Embodiment one, as attached figure 1 As shown, a siphon type adjustment device for the water inlet of an automatic runoff sediment monitor includes a water storage tank 21 and a siphon tube arranged at the bottom of the water storage tank 21, the water inlet of the siphon tube is located at the bottom of the water storage tank 21, and the bottom of the water storage tank 21 The wall is in the shape of a funnel or a spherical crown, and a water inlet 26 is arranged on the top of the water storage tank 21 .

[0028] The upper part of the water storage tank is used to enter the water. The impact of the water flow will keep the water flow in the water storage tank in a flowing state to avoid sedimentation. The siphon can make the sampled water flow stable and accurate, which is conducive to the accuracy of soil erosion monitoring data and get more results. Basic data for science.

[0029] The water storage tank 21 includes a bottom plate 211, a cylinder wall 212 and a top ...

Embodiment 2

[0033] Embodiment two, as attached figure 2 As shown, the siphon includes a U-shaped pipe 24 fixedly arranged on the bottom plate 211, and the two free ends of the U-shaped pipe 24 are respectively a first branch pipe 241 and a second branch pipe 242, and the first branch pipe 241 and the cone Corresponding to the small opening of the tubular bottom plate 211, the small opening of the tapered tubular bottom plate 211 is closed, the second branch pipe 242 extends downward through the bottom plate 211 to form a downspout 221, and a return pipe 221 is formed between the first branch pipe 241 and the bottom plate 211. Shuikou 231.

[0034] The inverted U-shaped tube can also realize siphon suction flow. The nozzle of the first branch tube 241 and the bottom plate 211 form a water return port 231, and the water sample is sucked out of the water storage tank. When the rainfall is small, the water storage tank stores water and reaches the top of the U-shaped tube. After that, it wi...

Embodiment 3

[0037] Embodiment three, as attached image 3 As shown, the siphon includes a water diversion pipe 25 communicated with the small opening of the tapered tubular bottom plate 211 and a U-shaped pipe 24 communicated with the other end of the water diversion pipe 25, and the two free ends of the U-shaped pipe 24 are respectively the first branch pipe 241 and a second branch pipe 242 , the first branch pipe 241 communicates with the water diversion pipe 25 , and the second branch pipe 242 extends downward to form the downpipe 221 .

[0038] The water diversion pipe 25 leads the sampling water to the nozzle of the first branch pipe 241. After the water level reaches the top of the U-shaped pipe, it will flow into the second branch pipe 242. The water in the water storage tank has no precipitation, and the sampling is uniform. After the siphon is formed, the water sample will evenly flow into the monitoring mechanism.

[0039]The top wall 213 is buckled on the top of the cylinder w...

Abstract

The invention relates to an automatic runoff and sediment monitor water inlet siphon type regulating device comprising a water storage tank and a siphon pipe which is arranged at the bottom of the water storage tank, wherein a water inlet of the siphon pipe is formed in the bottom of the water storage tank, a bottom wall of the water storage tank is funnel-shaped or sphere crown-shaped, a water inlet is formed in the top of the water storage tank, the water storage tank comprises a base plate, a cylinder wall and a top wall, the base plate is taper-tube-shaped, a big opening of the taper tube shaped base plate is in seamless connection with the cylinder wall, a small opening of the taper tube shaped base plate corresponds to the water inlet of the siphon pipe. Water is fed from the upper part of the water storage tank, the impact of water flow can ensure that the water flow in the water storage tank is always in a flowing state, so that a deposition phenomenon can be avoided; and by adopting the siphon pipe, the water flow for sampling can be stabilized and accurately sampled, and thus the automatic runoff and sediment monitor water inlet siphon type regulating device is beneficial to the data accuracy of water and soil loss monitoring and ensures that a relatively large amount of scientific basic data can be acquired.

Description

technical field [0001] The invention relates to an instrument for monitoring water and soil loss, in particular to a siphon type regulating device for a water inlet of an automatic runoff sediment monitor. Background technique [0002] At present, in soil and water conservation monitoring and observation experiments, the sampling of sediment is one of the most important links affecting the accuracy of experiments. The original method of stirring the muddy water manually in the bucket until it reaches a stable level, and then using the sampling bucket to take samples has a low precision, serious sediment deposition, and labor and manpower consumption. It brings a lot of inconvenience to the whole observation and test work, and even affects the progress of the monitoring work. The closest real sample cannot be obtained accurately, which seriously affects the accuracy of soil erosion monitoring. Contents of the invention [0003] The purpose of the present invention is to ov...
