ABSTRACT:
Security System for Sewer, Aqueduct, Telephone and Energy System Manhole Caps or Covers including an electromechanical cover (1), on the surface of which is placed an electromagnetic crane (2) that has a handle (3), and that has an emitting coil (4), a battery (5), an electronic card (6) and a control panel (7); inside a waterproof space at least partially enclosed by the electromechanical cover (1) are placed a receiving coil (8), electronic card (12) and two motors (9) that move a pin (10) that has bellows (11), and that are connected to an electronic card (12). The system operates by the emitting coil (4) transferring electromagnetic energy to the receiving coil (8), and at the same time sending an exclusive binary code. This produces the electricity to operate the electric motors that move the pins (10) that open or close the cover (1); and after the cover (1) is open, a constant magnetic field is produced in a single direction to enable the electromechanical cover (1) to be lifted for the necessary work to be carried out, and to return and position it in place and close it.
