Abstract
The invention discloses a moveable device for monitoring the content of sand of runoff silt distributed in different spaces. The structure of the device is as follows: a trash rack is arranged at an inlet of a triangular groove; a dirt intercepting belt driven by a motor is arranged in front of the trash rack; two dirt storages are respectively arranged at the two sides of the triangular groove; the inner side wall of the triangular groove is provided with a standard water gauge; a sampling hole is formed in the two-fourths part in the triangular groove; the bottom of the sampling hole is provided with a rubber pad; a current meter and a flow depth meter are erected at an interval at the three-fourths part in the triangular groove; a pipeline arranged at the bottom of the triangular groove is connected with an automatic silt collection system; a bracket and a winch are symmetrically arranged at the shore side in the middle of a water tank in which the triangular groove is formed; the top of the bracket is provided with a roller wheel; a steel wire rope of the winch is connected with the middle of the water tank. After the device is used, the problems that a runoff silt observation resource is wasted and the content of the sand at different runoff muddy water depths can not be measured in the prior art can be solved, so that the device is beneficial to the reutilization of a runoff silt observation station and the reduction of environmental pollution.
Description
technical field [0001] The invention relates to a monitoring device for systematically measuring different levels and depths of runoff silt discharged from various handle stations, especially for analyzing the content of fine particle silt at different depths and different levels of runoff silt, and monitoring through mobile runoff silt Sampling holes at different heights in different parts of the tank are used for time series sampling, and at the same time, the flow velocity and flow depth of the runoff sediment flowing through the mobile monitoring tank are automatically measured, and the sediment volume is sampled according to a certain time step for analysis. Background technique [0002] At present, many runoff and sediment monitoring sections will collect the time distribution process of the runoff and sediment passing through the station, but there is a lack of measurement methods and devices for the change process of the sediment concentration at different levels and ...
