[0022] The moving block 9 is slidably installed in cavity 1 and fixedly connected to the moving rod 8. The two round rods 10 are respectively installed in the two limit grooves. The limit blocks 11 are slidably installed on the two round rods 10. The two limit blocks 11 are respectively adapted to the two limit grooves. The outer walls of the two limit blocks 11 on one side close to each other are respectively fixedly connected to the outer walls on both sides of the moving block 9.

[0023] Two telescopic springs 12 are respectively slidably mounted on the two round rods 10 , the bottom end of the telescopic spring 12 is connected to the top of the limiting block 11 , and the top end of the telescopic spring 12 is connected to the top inner wall of the limiting groove.

[0027] The alarm 17 and the sensitive switch 19 are prior art and will not be described in detail here.

[0028] The working principle of the device for measuring the height of groundwater monitoring borehole filling provided by the utility model is as follows:

[0029] The first step: when using, pull the measuring rope 21 by hand and put the measuring mechanism 4 into the borehole 2, then gradually lengthen the measuring rope 21 to make the measuring mechanism 4 move downward gradually. When the measuring mechanism 4 is put in, the weight of the falling block 7 will drive the moving rod 8 and the moving block 9 to move downward, and the moving block 9 will drive the two limit blocks 11 to move downward and stretch the two telescopic springs 12, and will also drive the installation rod 14 and the soft pad 15 to move downward, so that the soft pad 15 enters the cavity 1 through the through hole (such as Figure 1 and Figure 3 shown);

[0030] The second step: when the pendant block 7 contacts the filler body 3, the pendant block 7 can be supported by the filler body 3. When the measuring rope 21 is slowly extended, the stretched telescopic spring 12 will reset and move because the filler body 3 supports the pendant block 7, which will drive the limit block 11, the moving block 9, the moving rod 8, the mounting block 13 and the mounting rod 14 to reset, so that the mounting rod 14 and the soft pad 15 pass through the opening and the soft pad 15 contacts the sensitive switch 19. When the soft pad 15 squeezes the sensitive switch 19 to make the circuit conductive, the alarm 17 will start to alarm, thereby reminding the user to stop releasing the measuring rope 21. After that, by observing the lowering length of the measuring rope 21 + the length of the measuring mechanism 4 (such as Figure 1 The measuring mechanism 4 shown in the state length) can know the height between the top of the filler body 3 and the top of the borehole 2, so it can be judged whether the filler body 3 reaches the filling position and whether it needs to continue to be thrown.
