Microwave leakage protection device for microwave asphalt pavement heater

Abstract

The invention discloses a microwave leakage protection device for a microwave asphalt pavement heater. The microwave leakage protection device comprises choke grooves, first metal rings, second metal rings and metal wires, wherein the choke grooves formed in the inner side of a flexible metal curtain consisting of the first metal rings, the second metal rings are arranged inside the first metal rings through the metal wires, and the metal wires are mutually woven to form a flexible metal net. The depth of the choke grooves is a quarter of microwave length. The first metal rings and the second metal rings are made of a metal material or a material plated with metal on the surface. The flexible metal net consisting of the metal wires is attached to the surface of the flexible metal curtain consisting of the first metal rings. The nodes of the flexible metal net consisting of the metal wires are located at the centers of the second metal rings. The microwave leakage protection device for the microwave asphalt pavement heater is simple in structure, good in microwave leakage protection effect and good in extensibility, can effectively attach to the ground tightly and is suitable for popularization and usage.

Description

technical field [0001] The invention relates to a protection device, in particular to a microwave leakage protection device suitable for microwave asphalt pavement heaters, and belongs to the technical field of protection devices. Background technique [0002] Microwave leakage protection is based on the principle of electromagnetic shielding. Electromagnetic radiation is effectively controlled within a limited space by using electromagnetic radiation suppression materials to prevent it from spreading outwards, so as to protect microwave leakage. At present, in asphalt pavement repair projects , in order to speed up the speed of pavement repair and improve the quality of repair, microwave asphalt pavement heaters are commonly used when heating the pavement, but most of the existing microwave asphalt pavement heater anti-microwave leakage devices mostly use fixed-structure metal mesh protection devices , this kind of metal mesh can not stretch freely, can not effectively clin...

[0002] Microwave leakage protection is based on the principle of electromagnetic shielding. Electromagnetic radiation is effectively controlled within a limited space by using electromagnetic radiation suppression materials to prevent it from spreading outwards, so as to protect microwave leakage. At present, in asphalt pavement repair projects , in order to speed up the speed of pavement repair and improve the repair quality, microwave asphalt pavement heaters are commonly used when heating the pavement, but most of the existing microwave asphalt pavement heater anti-microwave leakage devices mostly use fixed-structure metal mesh protection devices , this kind of metal mesh cannot stretch freely, cannot effectively cling to the ground, and the effect of preventing microwave leakage is not good. Therefore, a microwave leakage protection device for microwave asphalt pavement heaters is designed to solve the above problems
