Abstract

The invention relates to an open channel water level gauge for detecting siltation and a detection method thereof, belongs to the technical field of channel detection, and solves the problem that the siltation thickness is difficult to detect after channel siltation in the prior art. The open channel water level gauge comprises a measuring bridge, a driving motor, a detection tube, a sensor bracket, a displacement sensor, a water immersion sensor and a touch panel, the measuring bridge is erected above the channel and serves as a support of the open channel water level gauge; the driving motor is used for driving the detection tube to move; the sensor support is arranged in the detection tube, and the touch panel is fixedly mounted at the lower end of the sensor support; the water immersion sensor is mounted on the touch panel; the water immersion sensor is used for detecting the water surface position; and the displacement sensor is used for monitoring the displacement amount of the detection tube. The real water level and the sludge thickness are indirectly obtained by monitoring the stroke of the detection pipe.

Description

technical field [0001] The invention relates to the technical field of channel detection, in particular to an open channel water level gauge for detecting siltation and a detection method thereof. Background technique [0002] In my country, the backbone channels of large and medium-sized irrigation areas are mostly soil channels, and siltation is a common phenomenon in such channels. During long-term operation, soil erosion on rock slopes and deposition of sediment entrained in water transport are the main factors causing channel siltation. Sedimentation raises the channel and reduces the water-passing section. Over time, the water-passing capacity of the channel is constantly limited, and the engineering benefits cannot be fully exerted. Therefore, regular channel dredging is a common task in the management scope. Before the canal dredging, the measurement and calculation of the amount of earthwork deposited at the bottom of the canal is an indispensable technical work, ...
