The invention relates to a rod-type supporting structure earth sensor support. The rod-type supporting structure earth sensor support comprises an earth sensor device installation plate, a supporting plate assembly, a supporting rod assembly, an upper supporting base, a lower supporting base and installation angle boxes, wherein one side surface, which is arranged on the earth sensor device installation plate, of the supporting plate assembly is connected with the earth sensor device installation plate in an assembling manner, the supporting rod assembly is fixedly connected with a front supporting plate of the supporting plate assembly by virtue of an upper supporting base, the supporting rod assembly is connected with a satellite structural plate by virtue of a lower supporting base, two side supporting plates of the supporting plate assembly are respectively provided with an installation angle box and connected with the satellite structural plate by virtue of the installation angle boxes, and an earth sensor is installed on the earth sensor device installation plate. On the premise of guaranteeing the sufficient strength and rigidness, the occupied layout space of the support is small, the structural weight of the support is low, the appearance is simple and light, the layout sensitivity of the earth sensor is improved, and the restriction of the layout height of the earth sensor for the design of the support can be effectively solved.
