According to the number of pumping positions, pull the corresponding number of pumping pipes to extend, place the filter head in the water, and rotate the handheld disk so that the corresponding number of arc-shaped bars rotate to the front of the movable block. The lengths of the arc-shaped bars decrease from front to back, pushing the shielding sheet to move backward, and then start the water pump to pump water to the water tank;

[0020] The beneficial effects of the hydraulic tunnel drainage filtration and separation device of the present invention are:

[0023] Start the motor to drive the screw rod to rotate, so that the screw sleeve can drive the mounting plate to move left and right repeatedly. When the mounting plate moves to the left, the limit groove and the limit block can slide, so that the vertical bar is moved as the mounting plate moves to the left, and will not drive the scraper plate on the outer wall of the round rod to move. At this time, the scraper plate can push the debris on the filter plate out of the discharge port. When the vertical bar moves to the left of the stop bar, it will move to the right with the mounting plate. At this time, the limit groove and the limit block cannot slide. The vertical bar is blocked by the stop bar, which will drive the scraper plate to rotate, so that the scraper plate is tilted and away from the filter plate, so that the scraper plate will not push the filtered debris back to the right when it moves to the right.

[0024] When the motor starts, it will drive the cam to rotate. By repeatedly squeezing the abutment rod, the gas inside the air pressure box 1 and the air pressure box 2 can be exchanged back and forth, so that the piston plate 2 inside the air pressure box 2 can move up and down repeatedly. Under the toggle of the toggle rod, the two diversion pipes can be driven to swing slightly, and then the drawn water can be evenly diverted to the surface of the filter plate for filtration, avoiding the problem of filter accumulation.
