Figure 1-4 As shown, a fixing device for a bridge abutment settlement monitoring box based on a MEMS sensor according to an embodiment of the present invention includes a base 1, a mounting plate 8 on one side of the base 1, and a box body 7 above the mounting plate 8. Limiting blocks 14 are fixedly connected to both sides of the bottom surface of the box body 7, and one end of the limiting block 14 extends into the interior of the limiting grooves 15 opened on both sides of the top surface of the mounting plate 8. A screw 3 is fixedly connected to one side surface of the mounting plate 8, and one end of the screw 3 extends into the interior of the threaded hole 9 opened on one side surface of the base 1. A protective cover 6 is provided above the mounting plate 8 on the outside of the box body 7. A groove 5 is opened on one side of the top surface of the mounting plate 8, and a spirit level 4 is fixedly installed inside the groove 5. The base 1 is fixedly installed. After installation, the limiting block 14 on the bottom surface of the box 7 is inserted into the limiting groove 15 on the top surface of the mounting plate 8. When the magnet 16 in the limiting groove 15 is magnetically attracted to the limiting block 14, the box 7 can be fixedly installed on the top surface of the mounting plate 8. By rotating the screw 3 on one side surface of the mounting plate 8 and observing the level bubble 4 in the groove 5 on the mounting plate 8, the horizontal position of the box 7 can be adjusted. After leveling, the locking nut 2 on the outer surface of the screw 3 can be rotated to fix the screw 3 in the threaded hole 9 on the base 1, thus facilitating the installation and fixing of the box 7 and ensuring the accuracy and long-term stability of the monitoring data.
[0029] Please see Figure 1 and Figure 2The bottom surface of the protective cover 6 is fixedly connected to two sides of the insert block 11, and one end of the insert block 11 extends into the slot 12 opened on both sides of the top surface of the mounting plate 8. The bottom surface of the mounting plate 8 is provided with positioning bolts 13 through both sides, and one end of the positioning bolts 13 extends into the positioning hole 17 opened on the bottom surface of the insert block 11. By setting the protective cover 6 on the outside of the box body 7, the box body 7 on the mounting plate 8 can be effectively protected, avoiding corrosion caused by long-term exposure to external environmental factors such as water vapor and temperature changes, thereby helping to extend the service life of the equipment. When maintenance or repair is required, first unscrew the positioning bolts 13 to disengage them from the positioning hole 17 at the bottom of the insert block 11, and then move the protective cover 6 upward to disassemble it; then lift the box body 7 upward to separate the bottom limiting block 14 from the magnet block 16 in the limiting groove 15, thereby completing the disassembly of the box body 7, which facilitates disassembly and repair.
[0030] Please see Figure 1 and Figure 2 The protective cover 6 is matched with the box body 7, and the positioning bolt 13 is threadedly connected to the positioning hole 17. The protective cover 6 can be fixed by the use of the positioning bolt 13 and the positioning hole 17, thereby maintaining the stability of the protective cover 6 on the mounting plate 8.
[0031] Please see Figure 1 One end of the screw 3 is threadedly connected to the threaded hole 9, and a locking nut 2 is threadedly connected to the outer surface of the screw 3. By rotating the locking nut 2, the screw 3 can be fixed in the threaded hole 9, which can improve its firmness.
[0032] Please see Figure 1 and Figure 2 A magnet 16 is fixedly connected to the upper surface of the bottom end of the limiting groove 15. The limiting block 14 is attracted to the magnet 16. By using the magnet 16 and the limiting block 14, the limiting block 14 can be fixed in the limiting groove 15, thereby limiting and fixing the box 7 and maintaining its firmness.
[0033] Please see Figure 1 The base 1 has two mounting holes 10 on one side surface. The two mounting holes 10 are evenly distributed on one side surface of the base 1. The base 1 can be installed and fixed by passing a mounting nail through the mounting hole 10.
[0034] Please see Figure 1 and Figure 4 The plug 11 and the slot 12 are rectangular structures. The length and width of the plug 11 are smaller than the length and width of the slot 12. The plug 11 is inserted into the slot 12, which makes it easy to insert the plug 11 into the slot 12.
[0035] Working principle: After the base 1 is fixedly installed, the limiting block 14 on the bottom surface of the box 7 is inserted into the limiting groove 15 on the top surface of the mounting plate 8. When the magnetic block 16 in the limiting groove 15 is magnetically attracted to the limiting block 14, the box 7 can be fixedly installed on the top surface of the mounting plate 8. By rotating the screw 3 on one side surface of the mounting plate 8 and observing the level bubble 4 in the groove 5 on the mounting plate 8, the horizontal position of the box 7 can be adjusted. After leveling, the locking nut 2 on the outer surface of the screw 3 can be rotated to fix the screw 3 into the threaded hole 9 on the base 1, thus facilitating the installation of the box 7. The fixed design ensures the accuracy and long-term stability of the monitoring data. The protective cover 6 on the outside of the housing 7 effectively protects the housing 7 on the mounting plate 8, preventing it from being corroded by long-term exposure to external environmental factors such as moisture and temperature changes, thus helping to extend the service life of the equipment. When maintenance or repair is required, first unscrew the positioning bolt 13 to disengage it from the positioning hole 17 at the bottom of the insert block 11, and then move the protective cover 6 upward to disassemble it; then lift the housing 7 upward to separate the bottom limiting block 14 from the magnet block 16 in the limiting groove 15, thus completing the disassembly of the housing 7, which facilitates disassembly and repair.
