Technical Field
[0001] This utility model relates to the field of geological exploration equipment technology, and in particular to a ground fissure monitoring device. Background Technology
[0002] The importance of ground fissure monitoring lies not only in understanding the patterns of ground fissure activity, but also in using data analysis to aid in disaster trend prediction and providing a scientific basis for the effective use and planning of land resources. Traditional ground fissure monitoring often employs on-site surveys, manually measuring fissures with fissure measuring tapes, and summarizing the development patterns and trends of fissures based on data over a period of time. However, in geological exploration work in the same area, the number of ground fissures that need to be measured may be in the hundreds, making manual measurement inefficient and hindering the progress of geological exploration.

[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] Please see Figures 1-5 As shown, a ground fissure monitoring device includes a first anchor bolt 1, a second anchor bolt 4, a measuring device 9, and a measuring rope 3.
[0026] Anchoring components are provided at the lower ends of both the first anchor rod 1 and the second anchor rod 4. The anchoring components are used to fix the first anchor rod 1 and the second anchor rod 4 to the ground.
[0027] Specifically, the anchoring assembly includes a first insert rod 13, which is threadedly connected to the first anchor rod 1 and the second anchor rod 4.
[0028] More specifically, the anchoring assembly also includes a connector 14 and a second insert 15. The connector 14 is provided with a socket 1401 that is adapted to the first insert 13. The first insert 13 passes through the socket 1401 provided on the connector 14 and is connected to the first anchor 1 and the second anchor 4, fixing the connector 14 to the lower end of the first anchor 1 and the second anchor 4. The second insert 15 is threadedly connected to the connector 14.
[0029] The measuring device 9 is provided with a measuring slide 901. The outer wall of the measuring device 9 is provided with a length measuring scale and a first opening 902 and a second opening 903 that penetrate into the measuring slide 901. A measuring slider 10 is slidably provided in the measuring slide 901, and a damping element is provided in the measuring slider 10. The damping element is used to dampen the measuring slider 10 when it slides in the measuring slide 901. A measuring pointer 11 is provided on the measuring slider 10, and the measuring pointer 11 extends out from the first opening 902 and points to the length measuring scale. The measuring device 9 can be fixed on the second anchor rod 4.
[0030] Specifically, the first opening 902 is located on the lower side wall of the measuring device 9, and the second opening 903 is located on the upper side wall of the measuring device 9.
[0031] More specifically, the measuring device 9 includes a box body and a box lid. The bottom surface of the box body is open, and the box lid is fixed to the box body and completely covers the opening of the box body. The first opening 902 is located on the box lid, and the second opening 903 is located on the top surface of the box body.
[0032] Specifically, the damping components include a spring 16 and two ball bearings 17. The measuring slider 10 has through holes 1001 extending through its two opposite sides. The spring 16 and the two ball bearings 17 are both disposed within the through holes 1001, with the two ball bearings 17 positioned on either side of the spring 16 and abutting against the inner wall of the measuring slide 901. The damping effect of the measuring slider 10 sliding in the measuring slide 901 depends on the performance of the spring 16.
[0033] The above technical solution also includes a support rod 12, which is detachably connected to the measuring device 9 and is used to assist in supporting the measuring device 9 in order to improve the stability of the measuring device 9 fixed on the second anchor rod 4.
[0034] Preferably, the support rod 12 is a telescopic rod, and the optimal support effect can be achieved by adjusting the length of the support rod 12.
[0035] One end of the measuring rope 3 is used to connect to the first anchor rod 1, and the other end is used to pass through the second opening 903 into the measuring slide 901 and then connect to the measuring slider 10. The second anchor rod 4 is provided with a first guide wheel 5 and a second guide wheel 6, and the measuring device 9 is provided with a third guide wheel 7 and a fourth guide wheel 8. When one end of the measuring rope 3 is connected to the first anchor rod 1 and the other end is connected to the measuring slider 10, the first guide wheel 5 is used to guide the measuring rope 3 to the second guide wheel 6, the second guide wheel 6 is used to guide the measuring rope 3 to the third guide wheel 7, the third guide wheel 7 is used to guide the measuring rope 3 to the fourth guide wheel 8, and the fourth guide wheel 8 is used to guide the measuring rope 3 to the measuring slider 10.
[0036] The setup process for the ground fissure monitoring device is as follows:
[0037] First, fix the first anchor bolt 1 and the second anchor bolt 4 to the ground on both sides of the ground fissure. It is advisable that the first anchor bolt 1 and the second anchor bolt 4 be kept vertical.
[0038] Then the measuring device 9 is fixed to the second anchor rod 4;
[0039] Finally, one end of the measuring rope 3 is connected to the first anchor rod 1, and the other end is passed through the second opening 903 into the measuring slide 901 and then connected to the measuring slider 10. Simultaneously, the measuring rope 3 between the first anchor rod 1 and the measuring slider 10 sequentially passes through the first guide wheel 5, the second guide wheel 6, the third guide wheel 7, and the fourth guide wheel 8. Initially, the measuring rope 3 should be taut, and the measuring slider 10 should be positioned as close as possible to the end of the measuring slide 9 as possible to the second anchor rod 4.
[0040] It should be noted that after the ground fissure monitoring device is installed, the measuring rope 3 between the first anchor rod 1 and the first guide wheel 5 must be kept horizontal.
[0041] According to the above technical solution, as the ground fissures continue to develop, the measuring slider 10 will slide within the measuring slide 901. Geological survey personnel only need to periodically read the sliding distance of the measuring slider 10 to directly obtain the change data of the ground fissures, thereby enabling efficient monitoring of the development process of the ground fissures.
[0042] Please see Figures 1-2 As shown, in another embodiment, the first anchor rod 1 is provided with a measuring plate 2, and the measuring plate 2 is provided with an angle measuring scale.
[0043] It should be noted that after the ground fissure monitoring device is installed, the measuring rope 3 between the first anchor rod 1 and the first guide wheel 5 must be parallel to the measuring plate 2.
[0044] According to the above design, when the angle of the measuring rope 3 between the first anchor rod 1 and the first guide wheel 5 changes, it indicates that the ground fissure not only widens but also shifts downwards. Based on the sliding distance of the measuring slider 10 and the angle change of the measuring rope 3, the widening distance and the shifting distance of the ground fissure can be calculated using trigonometric functions.
[0045] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
