Description

TECHNICAL FIELD

[0002] In the field of hydrogeological survey, water resources management and geological disaster warning, accurate monitoring of underground water level is an important link to obtain key data. Currently, the commonly used underground water level monitoring device relies on the cooperation of a floating plate and a soft tape to measure. However, the traditional device has obvious defects in practical application. The inner wall of the monitoring well is not always completely vertical and may have protrusions, impurities, etc. When the floating plate floats up and down with the change of water level, it is easily affected by the well wall environment and deviates in position, which in turn causes the soft tape between the floating plate and the top plate to tilt.

[0003] The tilt of the soft tape directly causes errors in the measurement data. Especially in scenarios where the water level changes greatly or the monitoring well is deep, the errors will gradually accumulate, seriously affecting the accuracy of the monitoring data.

[0025] Specifically, by installing four groups of fixed pulleys 206 on the outer end of the float plate 205, at this time the outer surface of the four groups of fixed pulleys 206 is attached to the inner wall of the monitoring well, so that the four groups of fixed pulleys 206 limit the moving path of the float plate 205 floating up and down in the monitoring well, thereby keeping the soft tape 202 between the float plate 205 and the top plate 1 vertical, avoiding the position deviation of the float plate 205 and the soft tape 202 causing the measurement error of the soft tape 202, thus improving the accuracy of the device in the monitoring process.

[0026] The positioning assembly 4 comprises two groups of arc-shaped fixed plates 401, both of which are slidingly connected in the inside of the top plate 1, the inside of the arc-shaped fixed plate 401 is provided with a spring 405, the end of the spring 405 away from the arc-shaped fixed plate 401 is provided with a connecting plate 403, the connecting plate 403 is rotationally connected in the inside of the arc-shaped fixed plate 401, the side of the connecting plate 403 away from the arc-shaped fixed plate 401 is provided with a plurality of groups of insertion rods 404, the inner wall of the two groups of arc-shaped fixed plates 401 is provided with a fixed ring 402, the position of the fixed ring 402 is located at the upper end of the top plate 1, the upper surface of the top plate 1 is provided with two groups of clamping grooves, the two groups of arc-shaped fixed plates 401 are respectively slidingly connected in the two groups of clamping grooves of the top plate 1, the outer wall of the arc-shaped fixed plate 401 is provided with a groove, the spring 405 is mounted in the groove of the arc-shaped fixed plate 401, the connecting plate 403 is rotationally connected in the groove of the arc-shaped fixed plate 401;

[0027] Specifically, by slidingly installing the arc-shaped fixing plates 401 in the clamping grooves of the top plate 1, stepping on the two sets of arc-shaped fixing plates 401 drives the arc-shaped fixing plates 401 to slide downward in the clamping grooves of the top plate 1, and the lower surface of the fixing ring 402 is abutted to the upper surface of the top plate 1. At this time, the connecting plate 403 moves out of the clamping groove of the top plate 1, and the spring 405 has the characteristics of extension and contraction, so that the spring 405 pushes the connecting plate 403 to rotate in the recess of the arc-shaped fixing plate 401. The plurality of insertion rods 404 are inserted into the inner wall of the monitoring well from the end away from the connecting plate 403, so that the positioning assembly 4 limits the movement position of the top plate 1 at the opening at the top end of the monitoring well, avoiding the movement of the top plate 1 during use to cause errors in the measurement data of the measurement assembly 2; by installing the fixing ring 402 on the inner wall of the two arc-shaped fixing plates 401, the staff can push the two arc-shaped fixing plates 401 to slide in the two clamping grooves of the top plate 1 by stepping on the fixing ring 402, thereby shortening the time spent by the staff during installation of the positioning assembly 4; by abutting the lower surface of the fixing ring 402 to the upper surface of the top plate 1, the fixing ring 402 limits the upward and downward movement position of the top plate 1 at the outer end of the positioning assembly 4, avoiding the upward and downward movement of the top plate 1 during use.

[0028] Conversely, by pulling the fixing ring 402 to drive the two arc-shaped fixing plates 401 to slide upward in the two clamping grooves of the top plate 1, the arc-shaped fixing plates 401 push the connecting plate 403 to reset to the recess of the arc-shaped fixing plate 401 during sliding. At this time, the connecting plate 403 drives the insertion rod 404 to move out of the inside of the monitoring well when rotating, thereby completing the disassembly of the positioning assembly 4.
