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

[0026] This embodiment is an indoor soil tank test runoff sediment continuous sampling measurement and storage system, such as figure 1 shown. This embodiment includes: sampling subsystem 1, measurement subsystem 2, sample storage subsystem 3, control subsystem 4, cleaning subsystem 5, see figure 1 . The sampling sub-system includes: a plurality of sampling buckets surrounding the annular sampling crawler that rotates intermittently according to the water intake conditions, and the sampling bucket is connected with the annular sampling crawler through an automatic unlocking mechanism; the sampling sub-system is also set There is a sampling port 101 connected to the outlet pipe of the runoff of the soil tank, the sampling port is aligned with the upper mouth of a sampling barrel 102 and is provided with a preliminary water level gauge 103, and the preliminary water level gauge is electrically connected to the control subsystem , the control subsystem is connected with the mot...

Embodiment 2

[0046] 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.

[0047] Sampling barrels can be made of stainless steel or high-strength plastic. The valve can be opened and closed by electromagnetic switch control. The effect of snapping ring cooperates with the grab 1041 of annular sampling track, and snap hook is hooked on the snapping ring, and annular sampling track just can drive the sampling bucket operation. There can be 2-4 clamp rings, and more clamp rings can make the ring sampling track and the sampling barrel more stable, but too many clamp rings will make the system too complicated and prone to failure.

Embodiment 3

[0049] 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 Figure 5 .

[0050] The function 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 groove can slide along the track.

Abstract

The invention relates to a continuous sampling, measurement and preservation system and method for runoff sediment of an indoor soil trough test. The continuous sampling, measurement and preservation system comprises a sampling subsystem, a measurement subsystem, a sample storage subsystem, a control subsystem, a power supply subsystem and a cleaning subsystem, wherein the sampling subsystem comprises a plurality of sampling buckets which are arranged around the periphery of an annular sampling caterpillar band which rotates intermittently according to water taking conditions; the sampling buckets are connected with the annular sampling caterpillar band through an automatic unlocking mechanism. According to the continuous sampling, measurement and preservation system and method, the sampling buckets are driven by the annular sampling caterpillar band to continuously sample runoff generated by a soil trough and the number of times of sampling is recorded; meanwhile, each time of sampling is accurately metered through the measurement subsystem and completely unmanned automatic sampling and automatic measurement are realized; the number of times of sampling is accurately recorded and water and silt in each sampling bucket are accurately weighed, so that the completely automatic accurate measurement of the runoff in the soil trough is realized.

Description

technical field [0001] The invention relates to a system and method for continuous sampling, measurement and preservation of runoff sediment in an indoor soil tank test, which is a system and method for hydrological experiments, and a system and method for automatic measurement of water and sediment 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 mon...
