Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, an embodiment of the present invention provides an anti-theft on-line monitoring device 20 for a tower facility, which can be installed on the beam frame surface of a tower through bolts, as shown in fig. 1, and the installation position can be selected from the tower waist or the tower base of the tower.
As shown in fig. 2, the anti-theft online monitoring device 20 for tower facilities includes a vibration sensor 201, a signal analyzer 202, a power supply module 203, and a data transmission module 204.
The vibration sensor 201 is fixed on the tower body of the pole tower through a perforation and is connected with the signal analyzer 202 through a signal transmission line with a shielding layer;
as shown in fig. 3, the vibration sensor 201 includes a base 302, a sensing unit disposed on the base 302, and a housing 301 covering the sensing unit, where the sensing unit includes a spring 303, a bolt 304, a mass 305, and a piezoelectric element 306, which are sequentially stacked from top to bottom, the piezoelectric element 306 is composed of two piezoelectric sheets, and the spring 303 and the bolt 304 pre-load the mass 305. In the structure of the vibration sensor 201, the base 302 is rigidly fixed with a tower beam frame, and the mass block 305 only moves back and forth in the axial direction of the vibration sensor 201 under the traction action of the spring 303 and the bolt 304, but does not shake in a plane perpendicular to the axial direction, so that the piezoelectric element 306 can only deform in the axial direction of the vibration sensor 201, alternating charges (voltage) are generated on two surfaces of the piezoelectric element 306, and the output voltage can be connected with other equipment such as the signal analyzer 202 through a lead.
