If the fluctuation and influence on the test environment are small, at least two opposite sides of the connecting rod 3 need to be connected with a damping device 5, so as to ensure the damping effect.
Referring to fig. 1 and 2, the shock absorbing device 5 includes an upper housing 6, a piston rod 7, a damper 8, a shock absorbing spring 9, and a lower housing 10. The end of the shock absorber 5 connected with the connecting rod 3 is set to be the front end of the damper 8, and the end of the shock absorber 5 connected with the seabed detection robot 1 is set to be the rear end of the shock absorber 5.
