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

[0024] This embodiment is a continuous sampling and preservation system for indoor soil tank test runoff sediment, such as figure 1 , 2 , 3 shown. This embodiment includes: sampling subsystem 1, sample storage subsystem 2, control subsystem 3, cleaning subsystem 4, 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 motor that drives the e...

Embodiment 2

[0038] 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.

[0039] 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

[0041] 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 matched with the track 105, such as Figure 5 .

[0042] The function of the concave arc clamp groove is to cooperate with the track, 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 Figure 5 middle arrow direction) to combine and separate the annular sampling track and the sampling bucket. When sampling is required, the circular sampling crawler falls, so that the hook on the circular sampling crawler is separated from the fastening ring on the sampling bucket, the sampling bucket slides into the track, the track fits into the groove on the sampling bucket, an...

Abstract

The invention relates to a system and method of the preservation of the continuous sampling of indoor soil test runoff sediment. The system comprises a sampling subsystem, a sample storage subsystem, a control subsystem, a power source subsystem, and a cleaning subsystem; the sampling subsystem comprises multiple sampling barrels surrounding the annular sampling track based on the water status and the intermittent rotations, the sampling barrels by an automatic unlocking mechanism are connected with the annular sampling track; and the sample times are recorded, and storage is conducted by set intervals or randomly selected and picked sampling barrels, for future research, fully unmanned automatic sampling and extracting are achieved in the whole process, excavated runoff and sediment amount is accurately calculated by the statistic measurement of the sample times, full automation sampling and the storage of samples of the runoff and sediment process are achievable, the workload of personnel is significantly reduced, and manpower and experiment costs are saved.

Description

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