Portable depth measuring device for water level of dam

Abstract

The invention proposes a portable depth measuring device for water level of a dam. The depth measuring device includes a ball breaker piece, a measuring tape and a receiving system, wherein the measuring tape is a measuring tape which is flexible and capable of curling; the ball breaker piece is fixed to the end of the measuring tape; a needle cavity with a fixed needle is installed in the ball breaker piece; the needle cavity is provided with an inlet hole and a water vent hole; one end of the needle is located in the needle cavity, and the other end of the needle is electrically connected with a cable in the measuring tape; the cable is electrically connected with the receiving system; when a sounding operation is carried out, the measuring tape moves to a water surface under the traction of the ball breaker piece, and the receiving system is electrified to the needle through the cable, if the ball breaker piece is immersed in water to make the needle in the needle cavity contactingthe water, the receiving system sends out a notification message of contacting the water surface. The portable depth measuring device for the water level of the dam has the advantages of being good inprotective ability to adapt to a fast measuring and using environment, not easy to be wound, fast in measuring speed and good in precision.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a portable sounding device for dam uplift water level. Background technique [0002] As an instrument for monitoring the seepage state of the dam, the dam uplift pressure measuring point provides an important indicator for the safety of the dam. A total of 63 uplift pressure measuring points are arranged in Shuikou Dam, 34 of which are non-pressure measuring points all the year round. During manual comparison, it is necessary to measure the height from the water level in the measuring pipe to the nozzle, and obtain the water level elevation value of the measuring point through calculation. [0003] The original measurement method is to use the conductivity of water, put the weight attached to the double-core stylus into the measuring tube, when the double-core stylus touches the water surface at the same time and closes a passage, the buzzer will sound an alarm, and measure wit...

AI Technical Summary

Problems solved by technology

This method has problems such as easy deformation of the double-core stylus, repeated short-circuiting due to moisture, easy entanglement of the cable, long measurement time, and low accuracy.
