Adjustable Surface Runoff Monitoring Device for Soil and Water Conservation

Abstract

The present invention relates to an adjustable surface runoff monitoring device for soil and water conservation, which includes a box. A box cover is arranged at an opening on the top side of the box;a partition is arranged in the box and divides the box into left and right reservoirs; the top side of a piston is connected with the top side of the inner wall of a vertical pipe through a spring sleeved on the outer periphery of a piston rod; a floating plate is provided in the reservoir on the right side of the box; the floating plate is fixedly connected with the piston rod through a connecting rod; the top side of the box cover is fixed with a mechanical counter; an input shaft of the mechanical counter is connected with the connecting rod through a transmission device; a second throughhole is arranged in the middle of the right side of the box; a second inverted U-shaped pipe is sealed in the second through hole; and a drainage tube is arranged on the upper part of the left side ofthe box. The invention has the advantages of simple structure and ingenious design; the device is more reliable than an existing weighing measuring device; water is discharged through the siphon principle; compared with the existing tipping bucket type measurement, the device can meet market demand and is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of surface runoff monitoring devices, in particular to an adjustable surface runoff monitoring device for water and soil conservation. Background technique [0002] At present, the automatic observation of flow in the process of slope runoff is a difficult problem in field experiments. The automatic monitoring methods of slope runoff mainly include weighing type and tipping bucket type, which are mainly affected by manufacturing process, stable structure design, measurement range, measurement accuracy and error. Uncertainty and many other constraints; weighing measuring devices are generally controlled by a large number of electronic software, resulting in complex structures, difficult maintenance, and electronic devices have limited life and low reliability, while tipping bucket measuring devices are generally turned over in the tipping bucket When it is easy to generate large vibrations, it is easy to loosen the mea...

[0002] At present, the automatic observation of flow in the process of slope runoff is a difficult problem in field experiments. The automatic monitoring methods of slope runoff mainly include weighing type and tipping bucket type, which are mainly affected by manufacturing process, stable structure design, measurement range, measurement accuracy and error. Uncertainty and many other constraints; weighing measuring devices are generally controlled by a large number of electronic software, resulting in complex structures, difficult maintenance, and electronic devices have limited life and low reliability, while tipping bucket measuring devices are generally turned over in the tipping bucket It is easy to generate a large vibration when it is used, and it is easy to loosen the measuring device, thereby reducing the accuracy and failing to meet the actual needs. Therefore, we have invented an adjustable surface runoff monitoring device for water and soil conservation.
