Problems solved by technology

This traditional sampling method adopts manual sampling, which requires a lot of labor and repeated actions, and there will be large errors in experimental operations and timing. However, in practice, manual changing of buckets often cannot accurately grasp the accuracy of water collection.
Although multiple soil tanks can be used for simultaneous experiments, multiple water samples are taken at the same time, and then averaged to reduce the error of the experiment, but this will increase the cost of the experiment

Embodiment 1

[0023] This embodiment is a continuous sampling measurement system for indoor soil tank test runoff sediment, such as figure 1 shown. This embodiment includes: sampling subsystem 1, measurement subsystem 2, control subsystem 3, cleaning subsystem 4, see figure 1 . The sampling sub-system includes: a plurality of sampling barrels surrounding the endless track that rotates intermittently according to the water intake conditions, and the sampling barrel is connected with the endless track through an automatic unlocking mechanism; the sampling sub-system is also equipped with The sampling port 101 connected to the outlet pipe of the soil groove runoff, the sampling port is aimed at the upper mouth of a sampling barrel 102 and is provided with a preliminary water level gauge 103, and the described preliminary water level gauge is electrically connected with the control subsystem, so The control subsystem described above is connected with the motor that drives the endless track 10...

Embodiment 2

[0044] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment about the sampling bucket. The upper part of the sampling bucket described in this embodiment is rounded platform 1021, the lower part is cylindrical 1022, the bottom is provided with valve 1023, and the cylindrical part is provided with at least two fastening rings 1024, such as Figure 4 shown.

[0045] Sampling barrels can be made of stainless steel or high-strength plastic. The valve can be opened and closed by electromagnetic switch control. The function of the fastening ring cooperates with the grab 1041 of the annular track, and the grab is hooked on the fastening ring, and the endless track can drive the sampling barrel to run. There can be 2-4 clamp rings, and more clamp rings can make the ring track and the sampling barrel more stable, but too many clamp rings will make the system too complicated and prone to failure.

Embodiment 3

[0047] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment about the sampling bucket. The round platform part of the sampling bucket described in this embodiment is provided with a concave arc-shaped fastening groove 1025 that matches the track, such as image 3 .

[0048] The effect of the concave arc clamp groove is to cooperate with the track 105, and the track is embedded in the groove, so that the sampling bucket can slide along the track. The ring sampling crawler drop mechanism can make the ring sampling crawler move up and down (such as image 3 middle arrow direction) to combine and separate the ring track and the sampling bucket. When it is necessary to separate from the endless crawler, such as weighing or cleaning, the endless crawler will fall, so that the hook on the endless crawler is separated from the snap ring on the sampling bucket, and the sampling bucket slides into the track. Groove fit, for weighing o...

Abstract

The invention relates to a continuous runoff and sediment sampling and measuring system and method used in an indoor soil-bin test. The continuous runoff and sediment sampling and measuring system comprises a sampling subsystem, a measuring subsystem, a sample storing subsystem, a control subsystem, a power supply subsystem and a cleaning subsystem, wherein the sampling subsystem comprises a plurality of sampling barrels which are arranged around an annular crawler belt intermittently rotating according to the water intake condition; the sampling barrels are connected with the annular crawler belt through automatic unlocking mechanisms. Through the sampling barrels driven by the annular crawler belt, runoff generated in a soil bin is continuously sampled and the sampling times is recorded, and by using the measuring subsystem, each sample is accurately measured, so that fully-unattended automatic sampling and automatic measurement are achieved; through accurate measurement of the sampling time and accurate weighing of water and sediment in each sampling barrel, full-automatic accurate measurement of the runoff in the soil bin is achieved.

Description

technical field [0001] The invention relates to an indoor soil tank test runoff sediment continuous sampling measurement system and method, is a hydrological experiment system and method, and is a system and method for automatic measurement of water and sand on soil slopes. Background technique [0002] The observation experiment of water and soil loss process is an important experimental method to obtain parameters in the research and design of water and soil conservation research, water and soil loss control, and production and construction project water and soil loss prevention and control. In the experiment, an inclined soil tank is usually set in the artificial rainfall area, and the soil tank is filled with soil, which comes from the research area, and a water outlet is set in the middle part of the downstream of the soil tank. Its runoff and sediment process monitoring mainly adopts the principle of equal flow diversion to monitor based on the rainfall process. That ...
