Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a ground fissure measuring device. Background Art

[0002] Geological exploration refers to the activity of investigating and studying geological information such as rocks, minerals, geological structures, groundwater, etc. on the surface and underground of the earth. The main purpose of geological exploration is to obtain geological information and provide a scientific basis for mineral exploration, geological disaster prevention, land use planning, etc. Among them, the measurement of ground fissures is very important. The existence of ground fissures can reflect the underground structure and geological activities, which is of great significance to the prevention of geological disasters and the evaluation of geological environment.

[0003] In the prior art, there is a patent with application number CN202121499518.6, which provides a geological disaster crack measurement device, including a support frame and a measurement device, wherein two insertion rods that can be inserted into the soil on both sides of the crack are symmetrically arranged at the bottom of the support frame; the measurement device is arranged between the two vertical ends of the support frame in the horizontal direction, and the measurement device includes a first scale plate, a second scale plate and an adjustment device, wherein the second scale plate is sleeved inside the first scale plate and is slidably connected along the long side direction of the first scale plate; the adjustment device is arranged between the measurement device and the horizontal end of the support frame, and the adjustment device is hinged to the first scale plate and the second scale plate through a connecting piece. By setting an adjustment mechanism to adjust the extension length of the second scale plate and the first scale plate, the sum of the first scale plate and the second scale plate is used as the width value of the ground crack, and one person can complete the measurement, which is convenient and quick.

[0004] However, the above patent still has the following deficiencies during use:

[0046] When the utility model is in use:

[0047] First, install the main body of the device. Specifically, place the two bases 1 on the ground on both sides of the ground fissure. First, observe with the naked eye to make sure that the fissure is near the center position of the device; then, rotate the threaded rod 5 through the knob 6, so that the threaded rod 5 drives the installation assembly to slide down along the axis of the column 2 through the lifting plate 8, until the bottom end of the contact plate 13 in the width measurement assembly extends into the crack; then start the motor 24, and the motor 24 drives the bidirectional screw rod 25 to rotate. Under the limiting effect of the sliding contact between the connecting block 15 and the slide groove 10, the rotation of the bidirectional screw rod 25 can simultaneously drive the two Each mounting seat 14 drives the two contact plates 13 to perform a linear motion towards or away from each other. In the initial state, the two mounting seats 14 are in the closest limit position. When measuring the width, the two mounting seats 14 drive the two contact plates 13 to move away from each other until the two contact plates 13 contact the two sides of the crack, and then the motor 24 is turned off; at this time, the distance between the two contact plates 13 is the width value of the crack, and the coordinated setting of the laser rangefinder 17 and the baffle 16 can display the distance between the two contact plates 13 in real time, thereby achieving the purpose of measuring the crack width.

[0048] When the two contact plates 13 move away from each other synchronously, since the crack is not precisely centered with the device, one of the contact plates 13 will first contact the side of the crack; in the utility model, the strip mounting plate 9 is connected with the slide bar 11 by a damping sliding connection, so that when one contact plate 13 contacts the side of the crack first, the pressure between the contact plate 13 and the side of the crack drives the strip mounting plate 9 to slide adaptively on the slide bar 11 until the other contact plate 13 also contacts the side of the crack, at which time the crack is precisely in the center position of the slide groove 10; therefore, the damping sliding connection setting of the slide groove 10 and the slide bar 11 allows the utility model to make the strip mounting plate 9 adaptively slide and adjust within a certain range during the width measurement process, so that the crack is precisely in the middle position of the strip mounting plate 9, thereby improving the convenience and accuracy of the crack width measurement operation.

[0049] After completing the measurement of the width of the crack, the depth measuring assembly is located directly above the crack; at this time, the screw 19 is loosened, and the depth measuring rod 12 can slide between the second convex plate 18, and then the top end of the depth measuring rod 12 is held by hand to make the depth measuring rod 12 slide down at a constant speed until the bottom end of the depth measuring rod 12 touches the bottom. At this time, the depth value of the crack at this position can be obtained according to the scale 22 on the outer periphery of the depth measuring rod 12.

[0050] Therefore, the measuring mechanism of the utility model can measure the width and depth of the crack by setting the width measuring component and the depth measuring component, thereby improving the practicality of the device; the width measuring component effectively reduces the initial distance between the two contact plates 13 by setting the bidirectional screw rod 25 and the mounting seat 14, and compared with the prior art, improves the adaptability to the crack width size to a certain extent, and has good flexibility of use; and the distance between the two contact plates 13 can be obtained in real time by setting the baffle 16 and the laser rangefinder 17, that is, the reading work of the crack width measurement structure can be automatically completed, thereby improving the convenience of the measurement work.
