Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1, a kind of pinpoint vibration-testing apparatus in buried cable failure ground, including it is mounted on measurement vehicle
On column, installation delivery seat 3 on the column, the delivery seat 3 is equipped with the hole for 5 freely falling body of impact ball, is set to
Electromagnet 6 above the delivery bore for fixing and discharging impact ball 5, the power supply unit 10 for powering to electromagnet 6,
The delivery seat 3 has the timing sensor 7 of the time for measuring the whereabouts of impact ball 5.The column is height-adjustable
Structure, including with measure the fixed fixing pipe 1 of vehicle, be arranged in fixing pipe 1 mobile bar 2 movable up and down；Fixing pipe 1 and shifting
The dynamic car body for measuring vehicle is welded to together, and length is that height of the top away from ground is 1 meter.The delivery seat 3 and mobile bar
2, it is fixed by locking button 8 between mobile bar 2 and fixed link 1；Totally 8, button 8 is locked in the present embodiment, 4 are used for locking delivery
Seat 3 and mobile bar 2,4 be for locking mobile bar 2 and fixing pipe 1.The fixing pipe 1, which is equipped with, adjusts mobile bar height
The lifting wheel 9 of degree.The delivery seat is equipped with height sensor, the height for measuring delivery seat, that is, impact ball and falls
