Water level measuring apparatus capable of improving measuring accuracy

Abstract

The invention discloses a water level measuring apparatus capable of improving the measuring accuracy, relates to the field of measurement of underground water lines, and aims to solve the problem ofinaccurate measurement of the underground water lines due to interference of wet well walls by the conventional underground water level measuring apparatus. According to the technical scheme, the apparatus is characterized in that an original probe is replaced by a storage block, the storage block is provided with a first storage chamber and a second storage chamber in sequence along the directionfar from the growth of a transmission line, a separating plate for separating the first storage chamber and the second storage chamber is arranged between the first storage chamber and the second storage chamber, a contact connected with the transmission line is arranged in the first storage chamber, the separating plate is provided with a telescoping rod in a sliding manner, one end, located inthe first storage chamber, of the telescoping rod is provided with a contact piece for electrical connection, one end, located in the second storage chamber, of the telescoping rod is provided with afloating member driving contraction of the telescoping rod, and one end, close to the first storage chamber, of an inner sidewall of the second storage chamber is provided with a vent hole. Accordingto the apparatus, the goal of improving the measuring accuracy of the water level measuring apparatus is achieved.

Description

technical field [0001] The invention relates to the technical field of underground water level measurement, in particular to a water level measuring instrument for improving measurement accuracy. Background technique [0002] At present, the water level measuring instrument is one of the more accurate methods in water level measurement. It is usually used to measure the water level in wells, boreholes and water level pipes. It is especially suitable for the observation of groundwater levels in hydropower projects or the dam body seepage line of earth-rock dams. Manual inspection. The measuring instrument can be used not only during construction, but also as long-term safety monitoring of the project. [0003] refer to figure 1 , an existing water level measuring instrument produced in Canada, including a placement frame 1, a winding shaft 11 is arranged to rotate in the placement frame 1, a transmission line 2 for transmitting signals is wound on the winding shaft 11, and ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in the process of actual operation, a well to be measured with a small bore diameter will be encountered, and the inner wall of the well to be measured will form a large drop of water. When the detection head touches the inner wall of the well The indicator light will also light up when the water drops, giving the operator wrong instructions, which will lead to the problem of inaccurate measurement of the water level in the well. This problem needs to be solved urgently
