DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a kind of monitoring device for the settlement of structure foundation, including bottom plate 1, the upper side of bottom plate 1 is fixedly connected with stand 2, the outside of stand 2 is fixedly connected with limiting piece 3, the outside of limiting piece 3 is rotatably connected with rotating sleeve 4, the outside of rotating sleeve 4 is fixedly connected with gear ring 5, rotating mechanism is installed on the outside of stand 2, the outside of rotating sleeve 4 is fixedly connected with multiple groups of annular arrangement fixed rod 10, the end of fixed rod 10 is fixedly connected with connecting cylinder 11, the end of connecting cylinder 11 is fixedly connected with fixed square cylinder 14, and monitoring mechanism is installed on the inside of fixed square cylinder 14.

[0023] Rotating mechanism includes fixed plate 6, drive motor 7, rotating shaft 8 and gear 9, fixed plate 6 is fixedly connected to the outside of stand 2, drive motor 7 is fixedly connected to the upper side of fixed plate 6, rotating shaft 8 is fixedly connected to the lower side of drive motor 7, and rotating shaft 8 is rotatably connected between fixed plate 6, gear 9 is fixedly connected to the outside of rotating shaft 8, and gear 9 is engaged between gear ring 5, this design makes that device can remote control rotation, adapt to complex terrain, improve monitoring flexibility and accuracy.

[0024] The outer part of the fixed rod 10 is provided with a plurality of groups of equidistantly arranged screw holes 12, the end of the fixed rod 10 is located at the inner side of the connecting cylinder 11 and can be slidably connected therewith, the fixed rod 10 and the connecting cylinder 11 are threadedly connected with a fixed bolt 13, and the fixed bolt 13 is embedded in the inner side of one of the groups of screw holes 12. By adjusting the position of the fixed bolt 13 in the screw hole 12, the extension length of the connecting cylinder 11 can be easily changed, and the settlement monitoring at different positions can be realized.

[0025] The monitoring mechanism comprises a sliding rod 15, a counterweight 16, an abutting block 17 and a scale 18. The sliding rod 15 is slidably connected to the inner side of the fixed square cylinder 14, the counterweight 16 is fixedly connected to the bottom of the sliding rod 15, and the abutting block 17 is fixedly connected to the upper side of the counterweight 16. The trapezoidal cross-section design of the counterweight 16 enables the abutting block 17 to adaptively follow the unevenness of the ground surface, ensuring accurate monitoring of the settlement.

[0026] The counterweight 16 is a conical structure with a trapezoidal cross-section, the scale 18 is fixedly connected to the outer part of the sliding rod 15, and the upper side of the sliding rod 15 is fixedly connected with a limiting plate 19. This design not only enhances the stability of the device, but also enables the scale 18 to directly display the settlement data, making it convenient for recording and analysis.

[0027] The working principle of the monitoring device for the settlement of the foundation of a structure based on the embodiment is as follows. When monitoring the settlement of the foundation of a structure, the bottom plate 1 is first placed at the center of the entire detection area. The sliding rod 15 at the end of each connecting cylinder 11 will automatically slide down under the drive of the counterweight 16, so that the abutting block 17 comes into contact with the ground surface, and the upper surface of the fixed square cylinder 14 is aligned with the reading position of the scale 18 for reading and recording. When the local foundation of the structure settles, the counterweight 16 will automatically slide down with the sliding rod 15, while the position of the fixed square cylinder 14 will not change. When the point settles, the reading of the scale 18 corresponding to the point will change accordingly. Therefore, by observing the scale corresponding to the scale 18, it can be determined whether the point has settled. Moreover, by unscrewing the fixed bolt 13, the position of the positioning screw hole 12 can be changed, so as to realize the relative sliding between the connecting cylinder 11 and the fixed rod 10, change the extension length, and monitor the settlement of the foundation of the structure at different positions from the bottom plate 1. In addition, by operating the driving motor 7, the rotating shaft 8 can drive the gear 9 to rotate. Since the gear 9 is engaged with the gear ring 5, the gear ring 5 can drive the rotating sleeve 4 to rotate around the limiting member 3. Since the abutting block 17 has a trapezoidal cross-section, even if the contact surface between the abutting block 17 and the ground is uneven, the inclined surface of the abutting block 17 can still be driven to deflect in position under the force, so as to remotely control the settlement monitoring of each point of the foundation of the structure. In combination with the function of changing the extension length of the connecting cylinder 11, the settlement of each point can be accurately monitored in a large range, without the need to replace multiple monitoring devices for monitoring, which greatly improves the monitoring efficiency.

[0028] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
