By using the tester to detect resistance, frequency, damping, sensitivity distortion and other five technical indicators, but in the field operation, the seismic detector is inserted into the ground by manual operation, which will cause the seismic detector to produce a certain tilt. In this case, the seismic detector is also required to work normally, and the technical indicators are not out of tolerance. That is, the tilt test should be added when detecting the seismic detector. That is, the existing detector is required to be tested at 10°, 15°, 20° and other tilt angles, and the technical indicators are qualified.

[0003] The existing detector test platform is horizontal, and the technical indicators of the seismic detector in the vertical direction are detected. When the tilt test is performed, the horizontal test table needs to be turned over by the corresponding angle. However, the turning angle may not be accurate in actual operation, and the bottom of the test platform needs to be padded, which is not convenient to operate.

[0004] The existing test equipment often does not have angle adjustment function, which makes it impossible to test the detector in all directions, and is not conducive to accurately evaluating the performance of the detector.
