Provided is a charging protection circuit. The charging protection circuit includes a wireless charging base and a charging receiving circuit. The charging receiving circuit includes first receiving coils configured to receive electromagnetic waves from the wireless charging base; a high-permeability magnetic core coupled to the first receiving coils and configured to block electromagnetic waves opposite to the electromagnetic waves from the wireless charging base; a detection circuit coupled to the high-permeability magnetic core and configured to detect whether the high-permeability magnetic core has failed; and a power supply circuit coupled to the high-permeability magnetic core and configured to convert electromagnetic energy generated by electromagnetic waves into electric energy to supply power to a power receiving device. With the technical solution, the serious result caused by continuous charging of a wireless charger after a high-permeability magnetic core has failed is avoided, thus guaranteeing the security of a power receiving device.

Charging protection circuit

A large-span and special-shaped arch bridge, comprising a main girder (), a center abutment () served as a central bearing point and two auxiliary abutments () served as bearing points at two ends, wherein further comprising an arch-axis combination () and two arch-axis bending beams () presented as arcs projected upwards, the arch-axis combination being built on the center abutment () with two ends connected to the inner ends of the two arch-axis bending beams (), the outer ends of the two arch-axis bending beams () being built on the two auxiliary abutments (), the two arch-axis bending beams () being connected to the main girder () via a plurality of inhaul cables. A method for constructing said arch bridge is also disclosed. Through the dual-arch axis of two arch-axis bending beams, the bending strength of the cross-section of the arch bridge is significantly increased, the bending moment of the cross-section of the arch at the central bearing point is decreased, the vertical displacement at the haunch of the arch is lesser, and the deformation of the main girder is reduced, thus the force of the entire bridge is more reasonable, the construction cost can effectively be reduced and the construction period can be shortened.
