The water absorbing component 3 includes a water absorbing frame and a water absorbing pipe. The water absorbing frame is connected between the connecting frames 31. A plurality of water absorbing pipes are connected to the water absorbing frame. An external pipe 4 for connecting to an external water pump is connected to the upper middle part of the water absorbing component 3.

This device can be used when the mud to be precipitated and separated during subway construction. It should be noted that the mud to be precipitated is first poured into the precipitation frame 2 for precipitation. After the precipitation is completed, the position of the mud-water separation is observed through the observation window 21, and the driving component 71 is started at the same time, so that the driving component 71 drives the screw rod 72 to rotate continuously, and then the connecting frame 31 drives the water absorption component 3 to slide upward along the guide rod 73 to the lowest position of the clean water. Then, the clean water after the precipitation and separation in the precipitation frame 2 is extracted through the external pipe 4 and the water absorption component 3, and then the feed pipe 5 is opened to discharge the mud after separation and precipitation. When the mud in the feed pipe 5 is blocked, the dredging component 6 is started to dredge the feed pipe 5. Specifically, the servo motor transmits the rotational motion to the connecting rod and the rotating rod through the transmission mechanism (here, the bevel gear set). The function of the bevel gear set is to change the direction of power transmission (for example, from horizontal to vertical), and it may also involve deceleration or acceleration to ensure that the dredging rod obtains a suitable rotation speed and torque.

Cam mechanism: As a control mechanism, the cam may be designed to convert the continuous rotation of the servo motor into the reciprocating or specific trajectory of the dredging rod. For example, if the cam profile is properly designed, it can push the dredging rod to poke back and forth, or scrape along the wall of the feed pipe to loosen and remove the blockage.

Implementation of dredging: The dredging rod, driven by a motor and controlled by a cam, directly acts on the inside of the discharge pipe 5 to achieve the purpose of dredging.

Mud discharge: As the dredging work proceeds, the loosened mud can flow naturally under the action of gravity, or while the discharge pipe 5 continues to be opened, with the assistance of a certain flushing water flow, the mud can be discharged out of the pipeline system.

After the mud is discharged, the discharge pipe 5 can be closed. In summary, the sedimentation situation in the sedimentation frame 2 is observed through the observation window 21, so as to observe the mud-water separation position, and then it is convenient to adjust the position of the water absorption component 3 to absorb water, and through the cooperation between the driving component 71 and the screw rod 72, the position of the water absorption component 3 is automatically adjusted, avoiding the construction personnel to manually adjust the water absorption component 3, thereby improving the water absorption efficiency.

As shown in Figures 2 and 5, a filtering mechanism 8 is also included, which includes a hook 81, a mounting frame 82 and a filter screen 83. The lower part of the water absorption component 3 is slidably connected to the mounting frame 82, and the front and rear parts of the mounting frame 82 are connected to left-right symmetrical hooks 81 for assisting the mounting frame 82 to be clamped and fixed. The hooks 81 are clamped with the upper part of the water absorption component 3, and the mounting frame 82 is connected to a filter screen 83 for filtering mud.

It should be noted that when using the external pipe 4 and the water absorption component 3 to absorb the clean water in the sedimentation frame 2, the installation frame 82 protects the lower edge of the water absorption component 3, and the filter screen 83 filters the absorbed water flow to prevent mud from accidentally entering the water absorption component 3. When the filter screen 83 needs to be replaced, the hooks 81 are bent to the non-adjacent side to disassemble the installation frame 82, and then the new installation frame 82 is placed at the bottom of the water absorption component 3, so that the installation frame 82 slides upward, and the water absorption component 3 is clamped between the inclined surface on the hook 81 and the hook 81 on the installation frame 82. In summary, the water absorption process of the water absorption component 3 is filtered by the filter screen 83 to prevent mud from being accidentally sucked into the water absorption component 3, thereby improving the purity of water absorption and extending the service life of the machine.
