Description

Technical Field

[0001] This utility model relates to the field of foundation pit engineering technology, specifically to a multi-point inclination measurement and acquisition device for foundation pit engineering. Background Technology

[0002] Excavation of foundation pits is a dynamic process, but currently most foundation pits still rely on manual inspection for structural safety. This manual inspection method is inefficient, data collection is not real-time, and it is greatly affected by weather and human interference, which often leads to foundation pit construction safety accidents and causes incalculable losses.

[0003] Electronic information technology has increasingly penetrated the construction industry, solving many problems that were difficult to address in traditional construction methods. In modern construction processes, the real-time performance and accuracy of on-site data acquisition and monitoring systems have become crucial guarantees for construction safety and project quality. Because unpredictable changes often occur during construction, real-time feedback and analysis of monitoring information can effectively predict system trends and provide early warnings when potential hazards appear, enabling timely emergency measures.

[0004] A foundation pit inclinometer is an instrument used to measure the apex angle and azimuth angle of structures in foundation pit slope engineering. Existing foundation pit inclinometers can only be operated manually on-site, and the equipment, cable reel, and main body of the inclinometer are separate from the data collection and analysis equipment, making operation and on-site transport inconvenient. Furthermore, during long-term project construction, continuous measurements are required, necessitating repeated transport of the equipment in and out of the measurement site. This is problematic because the equipment has limited battery power and requires charging, and remote control for data acquisition is not possible. Typical foundation pit inclinometers can only collect data from one point at a time, unable to simultaneously measure data from multiple points. Therefore, a multi-point inclinometer data acquisition device for foundation pit engineering is proposed. Utility Model Content

[0030] In summary, this multi-point inclination measurement and acquisition device for foundation pit engineering is used by removing the winding box 21 and mounting frame 9 as needed. Then, the data acquisition and processing module 8 is placed inside the mounting slot 10. The operator then rotates the screw 12, causing it to push the clamping block 13 through the bushing, thus limiting the mounting frame 9 to the outside of the data acquisition and processing module 8. Next, the operator inserts one end of the mounting block 15 into the connecting slot 14. Then, the operator rotates the first worm gear 19, causing it to drive the ball screw 17 through the first worm wheel 18, thus rotating the ball screw 17. One end of the drive plug 20 is inserted into the mounting block 15 to fix the position of the mounting block 15. Then, the operator rotates the second worm gear 30, which drives the take-up roller 23 to rotate through the second worm wheel 29, causing the first wire 24 to be released from the outside of the take-up roller 23. Then, the first wire 24 is pulled out to the required length, and one end of the first wire 24 is connected to the end on the main control module 1. Multiple sensor modules 5 are connected in series through the connecting rod 2, connecting connector 3, connecting ball head 6, and connecting sleeve 7, and then moved by the guide module 4. Data is collected at the required measurement location and transmitted to the data acquisition and processing module 8. When not in use, one end of the first wire 24 is disconnected from the end on the main control module 1. Then, the operator resets and rotates the second worm gear 30, causing the second worm gear 30 to drive the second worm wheel 29 to reset and rotate. The second worm wheel 29 then drives the take-up roller 23 to take up the first wire 24. Then, the operator resets and rotates the first worm gear 19, causing the first worm gear 19 to drive the first worm wheel 18 to drive the ball screw 17 to reset and rotate. This causes the ball screw 17 to drive the insert block 20... Move the end out of the mounting block 15, and then the winding box 21 and the mounting block 15 can be removed from the bottom of the mounting frame 9. Then the operator resets and rotates the screw 12, so that the screw 12 drives the bushing and clamping block 13 to reset and move, releasing the limit state between the mounting frame 9 and the data acquisition and processing module 8. Then the data acquisition and processing module 8 is taken out from the mounting slot 10. When it is necessary to connect the solar panel to the solar charging interface, follow the above steps to install the winding box 21 with the power transmission line wound on the mounting frame 9, and connect the solar panel to the solar charging interface.
