Abstract

The invention discloses an inclined angle type scouring sensor and a manufacture and installment method thereof. The inclined angle type scouring sensor comprises a fixing plate, a U-shaped ring, a chain, an upper shell body, a lower shell body, a guide line, an inclined angle sensing module, a base plate, a sealing plate, a cushion block and a clump weight. In a scouring environment, changes of water flow can drive the inclined angle type scouring sensor to shake, measured inclined angle data change constantly, the state of soil mass is relatively stable, and the measured inclined angle data of the inclined angle type scouring sensor in soil almost do not change. A plurality of inclined angle type scouring sensors are mounted on different depth positions in the same place respectively according to certain intervals, and inclined angle data measured by the sensors are used for distinguishing a water body and the soil mass to determine the position of a mud surface. The position of the mud surface is judged by means of rangeability and frequency of the inclined angle data, and thus the method is not disturbed by temperature variation and other factors. The inclined angle type scouring sensor is simple in structure and convenient to mount, and can change measurement precision and the range of the measurement depth according to using conditions and requirements. Monitoring devices of the inclined angle type scouring sensors are mounted on multiple monitoring places to achieve regional scouring monitoring.
