Calibration and testing device of landslide monitoring device

Abstract

The invention discloses a calibration and testing device of a landslide monitoring device. The calibration and testing device of the landslide monitoring device comprises a first substrate and a second substrate. An end head of the first substrate is provided with a third substrate. A rotatable screw rod is placed on the first substrate. One end of the screw rod is connected with a speed changing box fixed on the third substrate. A control module is connected with a motor. A second moving plate matched with the screw rod in a threaded mode is provided with a first moving plate. A first screw hole matched with a first bolt in the threaded mode is formed in the first moving plate. The first bolt penetrates the first through hole in a first pressing plate provided with a groove and fixes the first pressing plate on the first moving plate. The landslide monitoring device is clamped between the first moving plate and the first pressing plate. A fixing hole is formed in the second substrate. A third through hole is formed in a fixing plate. The landslide monitoring device is clamped between the fixing plate and a second pressing plate. The landslide monitoring device is connected with a testing module. The calibration and testing device of the landslide monitoring device is simple in structure, reasonable in design, convenient to use and capable of effectively calibrating or testing the landslide monitoring device.

Description

technical field [0001] The invention relates to a calibration and testing equipment, in particular to a calibration and testing equipment of a landslide monitoring device. Background technique [0002] Landslides are a serious natural phenomenon. The existing devices for monitoring the deep displacement of landslides mainly include multi-point displacement meters, borehole inclinometers, coaxial cables and distributed optical fiber monitoring devices, especially the latter two monitoring devices. Due to the different parameters of the coaxial cable and optical fiber used, the corresponding quantitative displacement is different, which requires calibration or testing of the landslide monitoring device before the product leaves the factory or before use to ensure the test results in practical applications accuracy, but such a device has not been reported. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the above-ment...
