Embodiment 1
[0034] Such as Figure 1-6 As shown, the in-situ test transducer clutch mechanism provided in this embodiment includes a locking mechanism for setting on the in-situ test platform 1, and the locking mechanism is used to lock and unlock the connecting rod of the transducer 3 2. The locking mechanism includes at least two slidable blocks 4 and a driving mechanism for driving each block 4 to move. For example Figure 5 As shown, the number of clamping blocks 4 is two. All the blocks 4 are distributed along the axial direction of the connecting rod 2 . When each block 4 abuts against the connecting rod 2, the connecting rod 2 is locked. When each block 4 is separated from the connecting rod 2, the connecting rod 2 is unlocked.
[0035] The specific use process is: when the in-situ test platform 1 is about to reach the surface of the seabed sediment, the transducer 3 continues to penetrate vertically downward into the sediment, and after stopping the penetration, the driving m...

The invention discloses an in-situ test transducer clutch mechanism and an in-situ test platform, and the in-situ test transducer clutch mechanism comprises a locking mechanism which is arranged on the in-situ test platform and is used for locking and unlocking a connecting rod of a transducer, wherein the locking mechanism comprises at least two movable clamping blocks and a driving mechanism which is used for driving the clamping blocks to move, the at least two clamping blocks are distributed in the circumferential direction of the connecting rod, the connecting rod is locked when the clamping blocks abut against the connecting rod, and the connecting rod is unlocked when the clamping blocks are separated from the connecting rod. By means of the arrangement, the in-situ test transducer clutch mechanism can enable the connecting rod to be separated from the in-situ test platform during testing, and acoustic signals are prevented from being transmitted to the in-situ test platform; and after the test is finished, the connecting rod can be connected with the in-situ test platform, so the connecting rod and the transducer ascend along with the in-situ test platform, and a problem that the energy of the acoustic signal propagating in the sediment is reduced due to the fact that the acoustic signal propagates along the connecting rod and the in-situ test platform in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of in-situ testing of underwater sediments, in particular to an in-situ testing transducer clutch mechanism and an in-situ testing platform. Background technique [0002] Underwater sediments, such as the in-situ measurement technology of shear wave velocity and attenuation coefficient of seabed sediments, refers to the technology of placing instruments on the seabed for direct measurement. Acoustic in-situ measurement of seabed sediments can obtain the acoustic characteristic parameters in the true state of the seabed in situ, and can effectively avoid measurement errors caused by disturbance of sediments caused by sampling or transportation. Compared with laboratory acoustic characteristic measurements of sediment sampling , with higher precision and accuracy. [0003] At present, in the in-situ measurement of shear wave acoustics of seabed sediments, the in-situ test platform is usually lowered to the se...
