8. The sludge suction device for cleaning the sludge in the river channel of claim 6, wherein: at least one of the sewage suction vessels (1) has a sludge storage bin.
9. The method for absorbing sludge in river channel of the sludge absorbing device for cleaning sludge in river channel according to claim 8, wherein the method comprises the following steps: the method comprises the following specific steps:
the method comprises the following steps: the whole device is placed on the surface of the river water where dirt needs to be sucked, and a servo motor (37) is started to adjust the position of the dirt sucking device (4) according to the position where dirt needs to be sucked;
step two: starting a hydraulic cylinder (14) to push a piston (7) to move downwards, stopping the part, in a contraction shape, of the bottom of the piston (7) close to a sludge adsorption pipe (6), and then closing a first valve (21) and a second valve (26);
step three: the method comprises the steps that a lifter (2) is started to drive a sewage suction device (4) to descend, when the tip end of a sludge impurity filtering cover (9) touches river bottom sludge, a driving motor (31) is started to drive a sludge adsorption pipe (6) to rotate in the circumferential direction, when the sludge impurity filtering cover (9) is completely immersed into the sludge and the sludge adsorption pipe (6) is partially immersed into the sludge, the lifter (2) and the driving motor (31) are closed, then a hydraulic cylinder (14) is started to pull a piston (7) to move upwards, and the sludge is sucked into the sludge adsorption pipe (6);
in the sewage suction process, the driving motor (31) is intermittently started to drive the sludge adsorption pipe (6) and the sludge impurity filtering cover (9) to synchronously rotate in the circumferential direction, so that the sludge fluidity is improved, the overhead phenomenon of a sludge layer is prevented, and the sewage suction efficiency is improved;
step four: after the sewage absorption in the sludge adsorption pipe (6) is finished, starting the lifter (2) to drive the sewage absorption device (4) to ascend, so that the sewage absorption device (4) ascends to a position higher than the bin opening of the sludge storage bin of the sewage absorption ship (1) and stops, and then starting the servo motor (37) to drive the sewage absorption device (4) to move to the bin opening of the sludge storage bin of the sewage absorption ship (1);
step five: starting a hydraulic cylinder (14) to push a piston (7) to move downwards, and pushing out the sludge in the sludge adsorption pipe (6) into a sludge storage bin;
because the piston (7) of the sludge adsorption pipe (6) is in a contraction shape, part of sludge is remained in the sludge adsorption pipe, and at the moment, the first valve (21) is opened and the blower (19) is started to discharge the remained sludge into the sludge storage bin;
step six: after the sewage suction operation is completed, the first valve (21) is closed, the second valve (26) is opened, the water inlet of the water suction pump (24) is connected to the water pipe communicated with the water source, and then the water suction pump (24) is started to suck water to clean the sludge adsorption pipe (6).
