[0023] The solid-liquid separation and compression mechanism 6 includes a support box 601, in which a temporary storage box 602 is fixedly installed, and the bottom end of the temporary storage box 602 is provided with one end of a valve 603, and the other end of the valve 603 is connected to a separation compression box 604 fixedly installed in the support box 601, and one side of the separation compression box 604 is set as an opening. A compression mechanism located on one side of the separation compression box 604 is fixedly installed in the support box 601, and a sealing mechanism is provided in the support box 601. The compression mechanism and the sealing mechanism are used for solid-liquid separation of objects in the separation compression box 604, and a drain pipe 606 is provided on the support box 601.

[0024] A plurality of water outlet holes 605 are provided on the inner wall of the separation compression box 604 .

[0025] The compression mechanism includes a hydraulic cylinder 608 fixedly installed in the support box 601, and the output shaft of the hydraulic cylinder 608 extends into the separation compression box 604 and is fixedly installed with a compression plate 607, and the compression plate 607 contacts the inner wall of the solid-liquid separation compression mechanism.

[0027] The working principle of the novel suction device for the nuclear power cold source water intake causing marine life disasters provided by the utility model is as follows:

[0028] First, the net bag can be used to gather marine organisms and garbage floating on the surface of the seawater. Then, the lifting mechanism 2 and the reamer 3 are started to crush the marine organisms and garbage floating on the surface of the seawater. After that, the mixture is sent to the solid-liquid separation and compression mechanism 6 through the delivery pump 5. The mixture first enters the temporary storage box 602, and then enters the separation and compression box 604 through the valve 603 at the bottom of the temporary storage box 602. When the mixture enters the separation and compression box 604, the seawater is discharged through the water outlet 605 on the separation and compression box 604, and finally discharged from the support box 1 through the drain pipe 606. With the sedimentation over time, when there are more solid wastes such as marine organisms and garbage floating on the seawater surface in the separation compression box 604, the valve 603 is closed. At this time, the mixture is temporarily stored in the temporary storage box 602 and no longer enters the separation compression box 604. Then the hydraulic cylinder 608 is started, and the output shaft of the hydraulic cylinder 608 pushes the compression plate 607 to move in the separation compression box 604, thereby squeezing the fixed waste in the separation compression box 604, so that the seawater in the separation compression box 604 is further discharged, and the solid waste in the separation compression box 604 is compressed into a cake shape;

[0029] Then the hydraulic cylinder 608 is paused and the motor 615 is started. The motor 615 drives the worm 614 to rotate, the worm 614 drives the worm wheel 613 to rotate, the worm 613 drives the lifting shaft 611 to rotate, the lifting shaft 611 drives the lifting gear 612 to rotate, the lifting gear 612 drives the lifting tooth plate 610 to move upward, the lifting tooth plate 610 drives the blocking plate 609 to move upward, until the blocking plate 609 moves to a certain height, the motor is turned off, and the hydraulic cylinder 608 is started again to remove the waste objects pressed into a cake shape from the separation compression box 604, and then the hydraulic cylinder 608 is turned off to reset the compression plate 607, and the reverse start is started to reset the blocking plate 609, and the valve 603 can be reopened to allow the mixture to enter the separation compression box 604.
