Self-control vibratory sediment sampler

The invention discloses a self-control vibratory sediment sampler, and belongs to the fields of measurement and control technologies and underwater sediment collection. The sampler mainly comprises a vibrator, a connecting rod, a sampling pipe, a support frame and a control unit, wherein the vibrator provides a power source for the sampler; the support frame is used for ensuring vertical descending of the sampler; the instrument underwater penetration is detected through a pressure sensor; a single-chip microcomputer control module is used for transmitting a signal to a host for displaying; meanwhile, the startup and shutdown of the vibrator are controlled; the frequency of the vibrator can be adjusted as required on line through a speed regulator. The self-control vibratory sediment sampler has the beneficial effects of high sampling efficiency, working stability and small disturbance. The self-control vibratory sediment sampler has the characteristics of underwater operation controllability, simple structure, convenience in installation and capability of collecting original-state bedding formation sediment samples. The self-control vibratory sediment sampler is suitable for collecting sediments in the inland water areas of reservoirs, rivers, lakes and the like.
