Abstract

The invention relates to the technical field of lightning protection detection, and discloses a soil resistivity tester which comprises a box body, a probe used for making contact with soil and a test host used for measuring and displaying detection numerical values, the test host is arranged in the box body, a mounting frame is detachably arranged on one side of the box body, and the mounting frame is arranged on the other side of the box body. A driving assembly used for pressing the probe into soil is arranged on the mounting frame, the driving assembly comprises a driving motor arranged on the mounting frame, a driving gear fixedly connected with an output shaft of the driving motor and a driving rack meshed with one side of the driving gear, and the driving rack can vertically move under the action of the driving motor; the mounting frame comprises a support arranged below the driving rack, a first receding hole and a second receding hole which are distributed in the vertical direction are formed in the support, and the first receding hole and the second receding hole are both located under the driving rack and allow the probe to penetrate out. According to the device, the probe can be pressed into soil through the driving assembly, and the device has the effect of high working efficiency.

Description

technical field [0001] The present application relates to the technical field of lightning protection detection, in particular to a soil resistivity tester. Background technique [0002] The lightning protection detection of buildings in engineering construction is one of the essential processes before construction. As the characterization of soil conductivity, soil resistivity is one of the important factors that determine the design requirements of grounding body resistance. Therefore, in the design and calculation of grounding devices The soil resistivity of the construction site needs to be measured with a soil resistivity tester before setting parameters. [0003] In the related art, the Chinese patent with the notification number CN206178040U discloses a soil resistivity testing device based on the quadrupole method, which includes a casing, a probe, and a data line. The casing is provided with a display screen, a connecting hole A, and a connecting hole B. , Connecti...
