Description

Technical Field

[0001] This utility model relates to the technical field of anomaly detection equipment, specifically to a micro-motion device for detecting the limit state of anomalies in glass curtain walls. Background Technology

[0002] Traditional glass curtain walls, in their widespread application, have revealed problems such as light pollution and high energy consumption. Smart glass curtain walls, as an upgrade solution, optimize performance by integrating technologies such as thermal channel curtain walls and environmental monitoring systems. However, the long-term safety of the curtain wall structure still needs attention; for example, vibrations, deformations, and other anomalies may affect building safety. To address this, non-contact detection technology has emerged, using motion sensors to perform sensing, calculation, and analysis to achieve dynamic monitoring.

[0003] As a crucial component of building facades, the quality and safety of glass curtain walls directly impact the lifespan and safety of buildings. Therefore, effective monitoring of their condition is essential during the design, construction, and use of glass curtain walls.

[0004] The installation of glass curtain walls requires detection using an anomaly detector consisting of a magnetic induction sensor and a magnetic induction receiver. However, there is currently a lack of detection methods for the extreme states of the magnetic induction sensor and the magnetic induction receiver. Summary of the Invention

It simulates minute displacements that may occur in glass curtain walls, such as settlement, tilting, and expansion, and observes whether the tested anomaly detector can accurately capture and measure these changes, thereby verifying its performance limits. It provides a controllable, minute-level motion input for calibrating and testing glass curtain wall anomaly detectors, accurately calibrating or detecting the instrument's limiting operating state and measurement accuracy in different directions (X, Y, Z axes).

[0025] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] Example: Figure 1 , Figure 2 and Figure 3 As shown, a micro-motion device for detecting the limit state of a glass curtain wall anomaly detector includes an optical plate 6. Each of the four corners of the lower end of the optical plate 6 has a pad 8 for bolting and fixing to the optical plate 6. A three-axis micro-motion stage 1 is mounted on the optical plate 6, and a fixing platform 5 is located on the side of the three-axis micro-motion stage 1. The upper end of the optical plate 6 has 32 mounting holes 7 arranged in an array for fixing the three-axis micro-motion stage 1 and the fixing platform 5. A magnetic induction sensor fixing block 4, fixed to the fixing platform 5, is located between the fixing platform 5 and the three-axis micro-motion stage 1. The magnetic induction sensor fixing block 4 has a sensor fixing groove 17 at its upper end. A magnetic induction receiver fixing block 3, fixed to the three-axis micro-motion stage 1, is located between the fixing platform 5 and the three-axis micro-motion stage 1. The magnetic induction receiver fixing block 3 has a receiver fixing groove 16 at its upper end. A connecting plate 2, screwed and fixed to the micro-motion slider 15, is located between the three-axis micro-motion stage 1 and the magnetic induction receiver fixing block 3.

[0027] The three-axis micro-motion stage 1 includes a front-to-back adjustment seat 13 fixedly connected to the optical flat plate 6. A lifting adjustment seat 9 is located at the upper end of the front-to-back adjustment seat 13. A left-to-right adjustment seat 14 is located between the lifting adjustment seat 9 and the front-to-back adjustment seat 13. Each of the lifting adjustment seat 9, the front-to-back adjustment seat 13, and the left-to-right adjustment seat 14 contains a lead screw 11. One end of the lead screw 11 is fitted with a micro-motion knob 12. Micro-motion sliders 15 are located between the lead screw 11 and the front-to-back adjustment seat 13, between the lead screw 11 and the lifting adjustment seat 9, and between the lead screw 11 and the receiver fixing slot 16. Guide rods 10 are located at both ends of the lead screw 11 and are sleeved through the micro-motion sliders 15.

[0028] The magnetic induction sensor and magnetic induction receiver are fixed to the magnetic induction receiver fixing block 3 and the magnetic induction sensor fixing block 4, respectively. By rotating the micro-motion knob 12 on the lifting adjustment seat 9, the distance between the magnetic induction sensor and the magnetic induction receiver is gradually increased. During this process, the magnetic induction receiver alarms, and the displacement distance of the three-axis micro-motion stage 1 is recorded. By adjusting the micro-motion knob 12 on the front-rear adjustment seat 13 and the left-right adjustment seat 14, and repeating the operation, the limit trigger distances of the three axes will be obtained.

[0029] In summary, this micro-motion device for detecting the limiting state of glass curtain wall anomaly detectors simulates the minute displacements that may occur in glass curtain walls, such as settlement, tilting, and expansion, and observes whether the tested anomaly detector can accurately capture and measure these changes, thereby verifying its performance limits. It provides a controllable, minute-level motion input for the calibration and testing of glass curtain wall anomaly detectors, accurately calibrating or detecting the instrument's limiting operating state and measurement accuracy in different directions (X, Y, Z axes).
