An electrically driven multi-tube sampler according to claim 1 in which the back cover means comprises an L-shaped back cover baffle, drive springs, locating holes in the back cover baffle, trigger tips and trigger release holes; the bottom sealing baffle comprises a vertically arranged bottom sealing side plate and a horizontally arranged bottom sealing supporting plate, and the positioning hole is arranged on the bottom sealing supporting plate; the driving spring is connected between the back cover side plate and the mounting bracket, the positioning end of the hair releaser is clamped and connected with the positioning hole, and the triggering end of the hair releaser is connected with the triggering tip; the trigger pin penetrates through a bottom plate at the bottom of the mounting bracket, the clamping device presses the trigger pin downwards when moving downwards, the trigger pin moves downwards and pushes the trigger end of the hair releaser, so that the positioning end of the hair releaser, which is connected with the positioning hole, is separated from the positioning hole; when the positioning end is clamped with the positioning hole, the bottom sealing baffle plate exposes the sampling opening to allow the sampling tube to extend out of the sampling opening, and when the positioning end is separated from the positioning hole, the driving spring rebounds to drive the bottom sealing baffle plate to move so as to support and seal the free end of the sampling tube.
5. An electrically driven multi-tube sampler according to claim 4 in which the trigger is rod-shaped and includes the locating end and the trigger end in opposed relationship, the middle of the trigger being fixed to the mounting bracket by a pivot.
6. The electrically-driven multi-tube sampler according to claim 4, wherein the opposite two side surfaces of the bottom of the mounting bracket are provided with guide grooves matched with the side edges of the back cover supporting plate, the tail ends of the guide grooves are tilted upwards, and the bottom of the back cover supporting plate is stuck with a soft plate made of rubber.
7. An electrically driven multi-tube sampler according to claim 1 in which a camera is also placed in the middle of the mounting frame, the camera being connected to the control module and passing back image signals to the communication module.
8. An electrically driven multi-tube sampler according to claim 1 further comprising an external guard comprising a plurality of rings of greater diameter than the support coaxially disposed outside the support, the rings being connected to the support by a plurality of hub rods.
9. An electrically driven multi-tube sampler according to claim 1 in which the control module comprises a sealed pressure resistant control compartment, the control circuit board and the communications module being disposed within the sealed pressure resistant control compartment.
10. A sampling control method of an electrically-driven multi-tube sampler for controlling the electrically-driven multi-tube sampler according to any one of claims 1 to 8; the method is characterized by comprising the following steps:
the control module controls the power module to drive the electric drive type multi-tube sampler to move to a corresponding position according to a movement control signal transmitted by the armored cable;
and the control module sends a sampling control instruction to the corresponding sampling tube unit according to the sampling control signal transmitted by the armored cable, and controls the driving device to drive the sampling tube to sample.
