[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model provides a hydraulic ring geological crack measuring device, including a base 1, a movable block 21 inside the slide rail of the extended rod 2 sliding to the right, a gear 19 on the outside of the fixed rod 3 at the center of the movable block 21 rotating, the gear 19 slidingly connected to the toothed plate 20 inside the slide groove at the bottom of the extended rod 2, the movable block 21 sliding inside the slide groove of the extended rod 2, a connecting block 4 sleeved on the outside of the fixed rod 3, a slide rod 5 slidably connected inside the round hole of the connecting block 4, a support rod 7 at the bottom of the fixed rod 3 being pushed to the end to be measured, and the current values ​​of the clamping pin 6 and the measuring ruler 22 being observed, the clamping pin 6 being slidably set at the front end of the extended rod 2.

[0025] Specifically, a support rod 7 is fixedly connected to the bottom of the connecting block 4, a test head 9 is fixedly connected to the bottom of the support rod 7, a sliding seat 8 is sleeved on the outside of the support rod 7, the sliding seat 8 on the outside of the support rod 7 is slid down, the tightening box 10 on the outside of the sliding seat 8 releases the internal connecting wire 11, and the elastic ball 13 at the bottom of the connecting wire 11 enters the depth of the crack.

[0026] Furthermore, the shock-absorbing seat 14 inside the elastic ball 13 and the spring 15 on the outside dampen the elastic ball 13.

[0027] Furthermore, the central shaft 18 inside the elastic ball 13 drives the fan 16 to rotate. The air blown by the fan 16 blows towards the support plate 12. The air blows from the vent of the support plate 12 towards the elastic ball 13, and moves away from the obstruction by the reaction force of the air.

[0028] It is worth noting that there are two sets of breathable plates 17, which are evenly distributed on both sides of the support plate 12.

[0029] It is worth noting that a lifting rod 24 is fixedly connected to the top of the base 1, and the lifting rod 24 drives the extension rod 2 to rise and fall.

[0030] It is worth mentioning that the front end of the extension rod 2 is equipped with a measuring ruler 22, and the outer side of the extension rod 2 is fixedly connected with a signal column 25 and a light module 23 to emit signals. The signal column 25 receives the signals and displays them on the screen to read the data. In addition, the extension rod 2 is made of wear-resistant and waterproof material, which can be used for outdoor work.

[0031] Among them, fan 16 and light module 23 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle:

[0033] First, the staff inserts the base 1 into the outside of the crack to be measured and fixes it. Then, the staff pushes the moving block 21 inside the slide rail of the extension rod 2 to slide to the right. The gear 19 of the sleeve outside the fixed rod 3 at the center of the moving block 21 rotates. The gear 19 slides and connects with the toothed plate 20 inside the slide groove at the bottom of the extension rod 2. The support rod 7 at the bottom of the fixed rod 3 is pushed to the end to be measured. The staff observes and records the current values ​​of the clamping pin 6 and the measuring ruler 22. Then, the staff slowly slides to the other end of the crack. During the sliding process, the staff works with the light module 23 and the signal column 25 on the right side of the extension rod 2 to judge the sliding distance in conjunction with the measuring ruler 22. The width between the cracks can be obtained from the values.

[0034] Next, when it is necessary to measure the depth of the crack, for shallower cracks, the test head 9 at the bottom of the support rod 7 is pressed against the bottom of the crack to obtain a value. For deeper cracks, the top of the support rod 7 is aligned with the top of the crack, and the sliding seat 8 on the outside of the support rod 7 is slid downwards. The tightening box 10 on the outside of the sliding seat 8 releases the internal connecting wire 11, and the elastic ball 13 at the bottom of the connecting wire 11 enters the depth of the crack. When encountering uneven parts of the crack, the shock-absorbing seat 14 inside the elastic ball 13 and the spring on the outside... 15. Shock absorption is applied to the elastic ball 13. The central shaft 18 inside the elastic ball 13 drives the fan 16 to rotate. The air blown by the fan 16 blows towards the support plate 12. The air blows from the vent of the support plate 12 towards the elastic ball 13. The reaction force of the air will move it from the obstructed place. After the elastic ball 13 is blown out, under the action of gravity, the elastic ball 13 will fall to the deepest part of the crack. Then, the tightening box 10 is rotated to wind the connecting line 11 and lift up the lower end of the elastic ball 13. The depth of the crack can be determined by the connecting line 11.
