Description

Technical Field

[0001] This utility model relates to the technical field of sensor fixing devices, specifically to a sensor fixing device for protective nets. Background Technology

[0002] In the field of safety monitoring of protective netting, sensors are typically installed on the netting to monitor its stress and structural changes in real time, thereby promptly identifying potential safety hazards. However, current sensor fixing devices used for protective netting have many problems.

[0003] Some fixing devices have simple structures, merely securing the sensors to the protective netting with simple ropes or clips. This lack of stability makes them prone to loosening or displacement under external environmental influences, leading to decreased sensor accuracy or even malfunction. Some devices lack effective tension adjustment mechanisms; when the protective netting undergoes slight deformation due to stress, the sensors cannot maintain a tight fit against the netting surface, further affecting the accuracy of the monitoring data. Furthermore, the installation and removal of sensors in existing fixing devices are cumbersome, hindering later maintenance and replacement. Additionally, some devices cannot achieve stable data transmission between the sensors and external acquisition devices, failing to meet the needs of real-time monitoring. Utility Model Content
