Description

Technical Field

[0001] This utility model belongs to the field of geological monitoring technology, and in particular relates to a deep displacement monitoring device for geological disasters. Background Technology

[0002] Geological hazard deep displacement monitoring devices are instruments that use various technologies and methods to measure and monitor geological hazard activities and the dynamic changes of various inducing factors. They are an important basis for predicting and forecasting geological hazards. Inclinometers are often used for deep geological displacement monitoring. Current inclinometers require continuous data recording and depth adjustment during measurement, necessitating two operators: one to record data and the other to adjust the depth, increasing labor costs. A search revealed a patent with publication number CN221463494U, which discloses a geological hazard deep displacement monitoring device, including an inclinometer, a collar, and a positioning shell. The positioning shell has an arc-shaped positioning groove formed by internal recesses. A drive ring is located on one side of the positioning shell, forming a positioning channel between the drive ring and the positioning groove. A wire is installed at one end of the inclinometer, passing through the collar and positioning channel. Multiple annular slots are formed by recesses on the outer wall of the wire. Multiple inserts are installed on the outer surface of the drive ring, and corresponding inserts are inserted into the annular slots. A reduction motor is installed inside the drive ring to drive its rotation.

[0003] However, in actual use, the applicant found that when the wire is pulled or released by moving the annular slot on the wire through the plug on the drive ring, one side of the wire is directly attached to the positioning groove on the inner wall of the positioning shell. This causes the wire to slide and rub against the inner wall of the positioning groove during the movement of the wire, which will accelerate the wear of the wire and cause the wire to be damaged too quickly. In view of this, we propose a deep displacement monitoring device for geological disasters. Utility Model Content

[0012] This utility model discloses a deep displacement monitoring device for geological disasters. A collar is fitted onto a test pipe, and a rotating screw presses an arc-shaped clamping plate against the outer wall of the pipe. Two electric push rods drive two U-shaped supports on both sides, along with drive wheels, to move towards the center, causing the wheel grooves to abut against the conductor. A drive motor then rotates the drive wheels, which in turn pull and release the conductor, enabling the inclinometer to automatically rise and fall without manual control, thus reducing wear on the conductor. The arc-shaped clamping plate can be removed from the connecting seat by unscrewing the bolts and sliding the T-shaped slider out of the T-shaped groove, allowing for replacement. This allows the collar to be fitted and fixed onto test pipes of different diameters. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A deep displacement monitoring device for geological hazards includes a collar 1 and an inclinometer 3. Screws 11 are symmetrically threaded through the front and rear sides of the collar 1. The thread helix angle of the screws 11 is less than the equivalent friction angle, enabling the screws 11 to self-lock and prevent loosening. A handle 111 is fixedly installed at the end of the screws 11 located outside the collar 1. The end of the screws 11 located inside the collar 1 is rotatably connected to a connecting seat 12 via a bearing. An arc-shaped clamping plate 2 is fixedly connected to the connecting seat 12 via bolts 22. The left and right sides of the collar 1 are symmetrical. An L-shaped bracket 13 is fixedly installed. An electric push rod 4 is fixedly mounted on the outer wall of the upper end of the L-shaped bracket 13. The telescopic end of the electric push rod 4 movably passes through the upper part of the L-shaped bracket 13 and is fixedly connected to a U-shaped bracket 5. A drive wheel 7 is rotatably connected inside the U-shaped bracket 5, and a wheel groove 71 is provided in the middle of the drive wheel 7. A motor 6 is fixedly mounted on the front side of the U-shaped bracket 5. The output end of the motor 6 is coaxially connected to the wheel axle of the drive wheel 7. The two motors 6 rotate in opposite directions. A wire 31 is fixedly connected to the upper end of the inclinometer 3. 1. The wire 31 passes between the two wheel grooves 71. A connecting frame 8 is fixedly connected to the top of the U-shaped bracket 5. An arc-shaped guide seat 9 is fixedly connected to the upper end of the connecting frame 8. The two arc-shaped guide seats 9 can be spliced ​​into a complete guide tube to guide the wire 31, so that the wire 31 can pass smoothly between the two wheel grooves 71. The wire 31 passes through the guide tube formed by splicing the two arc-shaped guide seats 9. The upper and lower ends of the guide tube are provided with rounded corners to protect the wire 31. The drive wheel 7 abuts against the outer wall of the wire 31. By attaching the collar 1 to the test pipe and pressing the arc-shaped clamping plate 2 against the outer wall of the test pipe by rotating the screw 11, the two electric push rods 4 drive the U-shaped brackets 5 on both sides together with the drive wheel 7 to move towards the middle, and make the wheel groove 71 abut against the wire 31. The drive motor 6 drives the drive wheel 7 to rotate, and the rotation of the drive wheel 7 pulls and releases the wire 31, thereby enabling the inclinometer 3 to achieve automatic lifting and lowering without the need for manual traction control, and reducing wear on the wire 31.

[0022] A T-shaped slider 21 is provided on the outer side of the arc-shaped clamping plate 2. T-shaped grooves 121 are symmetrically provided on both sides of the connecting seat 12. The T-shaped slider 21 slides in conjunction with the T-shaped grooves 121. The lower end of the bolt 22 passes through the top of the arc-shaped clamping plate 2 and is screwed into the threaded hole at the top of the connecting seat 12. By unscrewing the bolt 22 from the connecting seat 12 and sliding the T-shaped slider 21 out of the T-shaped grooves 121, the arc-shaped clamping plate 2 can be removed from the connecting seat 12 and replaced. In this way, the collar 1 can be fitted and fixed on test pipes of different diameters.

[0023] Working principle: In use, select an arc-shaped clamping plate 2 with an inner diameter that matches the diameter of the pipe to be tested, and fix the arc-shaped clamping plate 2 to the connecting seat 12 with bolts 22. Put the collar 1 on the test pipe, and manually turn the handle 111 clockwise to drive the screw 11 to rotate. The rotation of the screw 11 can drive the arc-shaped clamping plate 2 to move inward, so that the arc-shaped clamping plates 2 on both sides abut against the test pipe. Then, the inclinometer 3 can be placed in the test pipe, and drive the two electric push rods 4 to drive the U-shaped supports 5 on both sides synchronously. As the instrument approaches, the U-shaped supports 5 on both sides can move the drive wheels 7 and the arc-shaped guide seats 9 on them, so that the grooves 71 on the two drive wheels 7 can abut against the wire 31, and the wire 31 can pass through the guide tube formed by the splicing of the two arc-shaped guide seats 9. By driving the two motors 6 to rotate in opposite directions, the two drive wheels 7 can be driven to rotate in opposite directions, thereby pulling and releasing the wire 31 through the two drive wheels 7, thus enabling the inclinometer 3 to automatically move up and down.
