A monitoring system for civil air defense projects

Abstract

This invention discloses a monitoring system for civil defense projects, including a mounting base. A limiting plate is welded to the outer edge of the mounting base, and a mounting plate is tightly fitted to the top of the limiting plate. This monitoring system for civil defense projects, by setting a lifting slider, allows for automatic disassembly of the monitoring equipment. Pressing an installation button within the mounting base causes the button to move a telescopic column via a button spring. The telescopic column then moves the lifting slider along an inclined groove within a moving plate. The sliding length of the moving plate is equal to the horizontal length of the inclined groove, and the moving length of the lifting slider is equal to the vertical height of the inclined groove. The thickness of the mounting plate is equal to the horizontal length of the inclined groove, and the inclination angle of the inclined groove is 45°. The moving plate slides along the inner wall of the mounting base via a sliding plate, the sliding length of which is equal to the thickness of the mounting plate, driving a telescopic rod. The telescopic rod, through a telescopic spring, moves the mounting plate, thus achieving automatic disassembly of the monitoring equipment.
