Description

Technical Field

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

[0002] Displacement measurement is crucial for geological disaster prevention. By measuring displacement, it is possible to detect the movement and changes of potential geological bodies in a timely manner. Early detection of minute displacements, such as the slow creep of soil on mountain slopes, can provide early warning before a disaster develops, preventing casualties and property damage. Furthermore, displacement data can clearly define the development trend of geological disasters; increases or decreases in the rate of displacement reflect the evolution process of the disaster. For example, an increased landslide displacement rate indicates a possible landslide in the short term, facilitating the early implementation of disaster prevention and mitigation measures. In addition, displacement measurement provides a basis for analyzing the causes of geological disasters. By combining topographical and soil characteristics information, a deeper analysis of the mechanisms can be conducted, disaster models can be improved, and the accuracy of disaster prediction and the targeted nature of prevention and control can be enhanced.

[0003] In geological disaster displacement measurement operations, the measurement process is generally as follows: first, the casing is buried in the soil, then the inclinometer is slowly lowered into the casing, and the inclination angle is measured segment by segment along the guide groove of the casing wall. The cumulative horizontal displacement at different depths relative to the bottom of the casing is calculated by integration, thereby monitoring the displacement of the deep part of the geological disaster. However, when it is necessary to retrieve the inclinometer, the operation method is for the staff to pull the cable connected to the inclinometer upward by hand, which affects the efficiency of the measurement work.

[0014] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Please see Figures 1 to 5 This utility model provides a geological disaster displacement measuring device, including two symmetrical first support bases 1, on which a take-up and release assembly is installed; a cable 2 is wound around the take-up and release assembly, and an inclinometer 3 is installed at the other end of the cable 2; a sleeve 4 is provided between the two first support bases 1; the inclinometer 3 is located in the sleeve 4; a guide tube 5 is installed between the two first support bases 1, and the guide tube 5 is located between the take-up and release assembly and the inclinometer 3; the cable 2 passes through the guide tube 5.

[0017] Using the above scheme: When it is necessary to measure geological hazards, firstly, the staff moves the device to the required measurement area, then the sleeve 4 is buried in the soil, and then the drive assembly is rotated to detach the cable 2. At the same time, the inclinometer 3 falls from the guide tube 5 to the preset position inside the sleeve 4. After the inclinometer 3 is started, the inclinometer 3 will detect the displacement position. After the measurement is completed, the cable 2 is pulled up by rotating the drive assembly in the opposite direction, thus avoiding the need for manual lifting of the inclinometer 3.

[0018] Furthermore, the take-up and take-down assembly includes a first rotating shaft 6 rotatably connected to the first support base 1, a spool 7 mounted on the first rotating shaft 6, and the cable 2 wound around the spool 7; a first gear 8 is mounted at both ends of the first rotating shaft 6; a second gear 9 meshes with one side of the first gear 8, and a second rotating shaft 10 is mounted on the central part of the second gear 9.

[0019] Furthermore, a first helical gear 11 is mounted on the second shaft 10 near the second gear 9; a second helical gear 12 meshes with one side of the first helical gear 11, and a third shaft 13 is mounted on the central part of the second helical gear 12; the third shaft 13 is rotatably connected to the top of the first support base 1.

[0020] Furthermore, a first mounting bracket 14 is installed on the first support base 1; a first rotating rod 15 is rotatably connected to the first mounting bracket 14, and a guide wheel that contacts the cable 2 is fixedly connected to the first rotating rod 15; a first synchronous pulley 16 is installed at one end of the first rotating rod 15 and at one end of the third rotating shaft 13, and a synchronous belt 17 is sleeved on the first synchronous pulley 16.

[0021] Furthermore, a first motor 18 is installed on the side wall of the first support base 1, and one end of the first rotating shaft 6 is fixedly connected to the output end of the first motor 18.

[0022] Using the above scheme: In use, the output end of the first motor 18 drives the first rotating shaft 6 to rotate, and the first rotating shaft 6 drives the first gear 8 to rotate together. Since the first gear 8 and the second gear 9 mesh with each other, when the first gear 8 rotates, it drives the second gear 9 to drive the second rotating shaft 10 to rotate. The first helical gear 11 and the second helical gear 12 on the second rotating shaft 10 mesh, transmitting power to the third rotating shaft 13. The first synchronous pulley 16 on the third rotating shaft 13 is connected to the first synchronous pulley 16 on the first rotating rod 15 through the synchronous belt 17, so that the first rotating rod 15 rotates synchronously. The rotation of the first rotating rod 15 drives the guide wheel to rotate synchronously. After the guide wheel contacts the cable 2, it causes the cable 2 to disengage from the spool 7, so that the inclinometer 3 gradually descends into the sleeve 4. After the measurement is completed, the first motor 18 rotates in the opposite direction, and the spool 7 and the guide wheel also rotate in the opposite direction, rewinding the cable 2 back onto the spool 7, completing the lifting process of the inclinometer 3.

[0023] Furthermore, each of the side walls of the first support base 1 is provided with a first slide rail 19; a first slider 20 is slidably connected in the first slide rail 19, and a plug rod 21 is installed on the lower side of each first slider 20.

[0024] Furthermore, a first spring 22 is fixedly connected to the top of the first slider 20; the other end of the first spring 22 is fixedly connected to the first support base 1, and a first fixing hole 23 is provided on the first slider 20; a plurality of second fixing holes 24 are provided on the side wall of the first support base 1, and a fixing rod 25 is installed in the first fixing hole 23; the other end of the fixing rod 25 can be inserted into one of the second fixing holes 24.

[0025] The above scheme is adopted as follows: When the device is moved to the required measurement area, the bottom surfaces of the two first support bases 1 are brought into contact with the ground. Then, the operator pulls the first slider 20 to move downward in the first slide rail 19. When the first slider 20 moves, it will drive the insertion rod 21 to move downward gradually. After the insertion rod 21 moves to the preset position, the insertion rod 21 will pass through the bottom of the first support base 1 and be inserted into the soil. Then, the fixing rod 25 is inserted from the first fixing hole 23 into one of the second fixing holes 24 to fix the insertion rod 21, thereby improving the stability of the device during the measurement process.

[0026] It should be noted that after the measurement work is completed, the insertion rod 21 is removed from the second fixing hole 24, and the elasticity of the first spring 22 is used to pull the first slider 20 to move in the opposite direction in the first slide rail 19, thereby removing the insertion rod 21 from the soil and releasing the fixation of the first support seat 1.

[0027] The working principle of this utility model: When geological hazards need to be measured, the device is first moved to the required measurement area by the staff. Then, the casing 4 is buried in the soil. The output end of the first motor 18 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the first gear 8 to rotate together. Since the first gear 8 and the second gear 9 mesh with each other, when the first gear 8 rotates, it drives the second gear 9 to drive the second rotating shaft 10 to rotate. The first helical gear 11 and the second helical gear 12 on the second rotating shaft 10 mesh to transmit power to the third rotating shaft 13. The first synchronous pulley 16 on the third rotating shaft 13 is connected to the first synchronous pulley 16 on the first rotating rod 15 through the synchronous belt 17, so that the first rotating rod 15 rotates synchronously. The rotation of the first rotating rod 15 drives the guide wheel to rotate synchronously. After the guide wheel contacts the cable 2, it causes the cable 2 to detach from the reel 7, so that the inclinometer 3 gradually descends into the casing 4. After the measurement is completed, the first motor 18 rotates in the opposite direction, and the reel 7 and the guide wheel also rotate in the opposite direction, so that the cable 2 is rewound back to the reel 7, completing the lifting process of the inclinometer 3.
