Abstract
Description
Technical Field
[0001] The utility model belongs to the field of rock and soil survey borehole water level measurement and relates to a borehole water level measuring device. Background Art
[0002] The water level measurement in geotechnical boreholes mainly focuses on the water level inside the borehole, specifically, the vertical distance from the borehole mouth to the groundwater surface (i.e., water level). This measurement can help us understand the location and change trend of the groundwater level, which is very important for geotechnical engineering, water resources management, and environmental monitoring. When measuring the water level, professional water level measuring instruments are usually used, such as water level gauges and electric water level meters. These instruments can accurately measure the water level height through different principles and technologies. For example, a water level gauge may use a pressure sensor to measure the pressure of the liquid and obtain the depth of the water level by conversion; while the electric water level meter reads the value on the wire after the measuring clock contacts the liquid surface through the circuit connection, thereby determining the water level depth. When measuring, most rock formations will produce water seepage, which will interfere with the built-in electric water level sensor of the existing borehole water level measurement device and affect the measurement results. At the same time, the existing borehole water level measurement device lacks protection for the electric water level sensor, which causes it to collide when moving up and down along the borehole wall, causing it to be damaged.
[0003] Therefore, the utility model provides a borehole water level measuring device to solve the above problems. Utility Model Content

[0006] As a preferred solution of the utility model, the aperture of the countersunk hole is larger than the diameter of the telescopic shaft of the micro electric push rod; such a design makes it easy for the water on the water surface to be measured to flow in through the gap between the telescopic shaft of the micro electric push rod and the countersunk hole when the telescopic shaft of the micro electric push rod moves downward, so that the water comes into contact with the electrical water level sensor.

[0008] As a preferred solution of the utility model, the left end of the rotating shaft is fixedly connected to an L-shaped rocker arm; by adopting the L-shaped rocker arm, it is convenient to retract and release the waterproof wire.
[0009] As a preferred solution of the utility model, a tightening screw rod is provided on the vertical arm of the T-shaped bracket on the right side, and the end of the tightening screw rod is squeezed and tightened against the right side wall of the winding roller; by adopting the tightening screw rod, the waterproof wire can be flexibly and temporarily positioned, which facilitates the observation of the scale on the waterproof wire.
[0010] The beneficial effects of the utility model are as follows: by embedding the electric water level sensor in the measuring bottle, it is convenient to avoid the collision of the electric water level sensor with the rock wall during the process of inserting the electric water level sensor downward into the borehole or pulling it upward out of the borehole, thereby realizing protection of the electric water level sensor; at the same time, for the water level detection of the borehole with multi-layer water seepage, a micro electric push rod is installed in the measuring bottle, and the first sealing rubber ring and the second sealing rubber ring above and below the micro electric push rod are used to realize temporary sealing of the electric water level sensor, thereby ensuring that when entering the rock layer with water seepage in the borehole, the electric water level sensor is prevented from contacting with the seepage water, thereby causing errors in the measurement results.

DETAILED DESCRIPTION

The waterproof wire 4 is provided with a measuring scale. The waterproof wire 4 is wound on the winding mechanism 5. The winding mechanism 5 includes a winding roller 51. A rotating shaft 52 is fixedly inserted in the winding roller 51. The left end of the rotating shaft 52 is fixedly connected to an L-shaped rocker arm 521. The left and right ends of the rotating shaft 52 are movably inserted into the middle part of the vertical arm of the T-shaped bracket 53. The upper ends of the left and right T-shaped brackets 53 are fixedly connected to the left and right ends of the T-shaped hanger 54 respectively.
