When the guide plate rotates to the roller, the roller is pushed by the inclined structure, and the roller moves along the guide groove. At this time, the rotating wheel rotates an angle, and the roller slides out of the guide groove. The gears are then moved back and forth in a circle so that the rollers rotate for one circle and the wheels rotate for one angle intermittently. The transmission shaft drives the driven shaft to rotate intermittently. When the driven shaft rotates, the half gears are driven to rotate. The half gears rotate and alternately mesh with the racks on both sides of the fixed frame. The fixed frame is fixed. The reverse force of the half gears causes the floating plate to move vertically. After the cleaning plate reciprocates horizontally for one cleaning, the floating plate is vertically displaced for a distance to clean the next section of the net. After a vertical reciprocating cycle, the gripper releases the net and the rack moves to the next area, thereby achieving comprehensive cleaning of the net. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the transmission mechanism 9 links the vertical moving mechanism 8 to intermittent movement, so as to achieve vertical movement of the cleaning plate 12 and realize comprehensive cleaning of the net.

[0029] Furthermore, the power supply of the device is provided by the cage or the ship power supply through the umbilical cable, and the operator controls the propeller through the controller to adjust the underwater posture and position.

[0030] Furthermore, counterweights are fixedly installed at the four corners of the bottom of the frame 1, the gripper 6 includes a U-shaped seat 61, the U-shaped seat 61 is fixedly installed at one end of the fixed frame 5 away from the frame 1, a rotating shaft 62 is rotatably sleeved in the fixed frame 5, one end of the rotating shaft 62 passes through the side wall of the frame 1 and is fixedly connected to the output shaft of the motor 63, the other end of the rotating shaft 62 passes through the middle of the U-shaped seat 61 and is fixedly installed with a worm 64, worm wheels 65 are rotatably installed in the inner cavities at both ends of the U-shaped seat 61 through pin shafts, the worm wheel 65 engages with the worm 64, and clamping rods 66 are fixedly installed on the two worm wheels 65.

[0031] Through the above technical solution, the motor 63 drives the rotating shaft 62 to rotate, so that the worm 64 drives the two worm wheels 65 to rotate, so that the clamping rod 66 clamps or releases the net.

[0032] Furthermore, the horizontal moving mechanism 7 includes a driving shaft 72, a driving shaft 72 is rotatably sleeved between the inner walls of the floating plate 11, a motor 71 is fixedly installed on the outer wall of one side of the floating plate 11, the output shaft of the motor 71 is fixedly connected to the driving shaft 72, a conveying roller 73 is fixedly sleeved on the driving shaft 72, a slider 74 is slidably sleeved on the conveying roller 73, one side of the slider 74 slides and fits the inner wall of the floating plate 11, and the other side of the slider 74 is installed on the outer wall of the cleaning plate 12 by bolts, a push-pull groove 75 is opened on the circumferential outer wall of the conveying roller 73, a slide bar 76 is fixedly installed on the inner wall of the slider 74, the slide bar 76 is slidably engaged with the push-pull groove 75, the end of the driving shaft 72 away from the motor 71 is connected to the transmission mechanism 9, the push-pull groove 75 is two spiral grooves with the same head and tail, and the two spiral grooves are symmetrically distributed along the axis of the driving shaft 72, and the number of spiral turns of the spiral groove is half a turn, and the diameter of the slide bar 76 is equal to the width of the spiral groove.

[0033] Through the above technical solution, the motor 71 drives the driving shaft 72 to rotate, thereby causing the conveying roller 73 to rotate. When the conveying roller 73 rotates, the push-pull groove 75 pushes the sliding rod 76, causing the sliding block 74 to reciprocate along the floating plate 11, thereby causing the cleaning plate 12 to horizontally reciprocate the net area fixed by the gripper 6 for external cleaning.

[0034] Furthermore, the cleaning plate 12 is an insulating fixed plate on which a plurality of electrode pairs are arranged facing each other, and a seawater conductivity sensor and a camera are fixedly mounted on an outer wall of one side of the frame 1 close to the cleaning plate 12 .

[0035] Through the above technical scheme, the conductivity of seawater, the amount and thickness of attachments, etc. are detected by seawater conductivity sensors and cameras, the pulse voltage amplitude is determined, and high-voltage pulses are discharged in the water to produce cavitation bubbles. The shock wave effect when cavitation bubbles are generated and the cavitation jet effect and shock wave effect when they collapse are used to remove attachments on the cage net, thereby achieving the purpose of efficient cleaning.

[0036] Furthermore, fixed blocks 13 are fixedly installed at both ends of the top of the floating plate 11, a shaking shaft 14 is rotatably sleeved between the fixed blocks 13, a plurality of cams 15 are fixedly installed on the shaking shaft 14, a transmission belt is sleeved between one end of the shaking shaft 14 and the driving shaft 72, the plurality of cams 15 are evenly distributed along the axial direction of the shaking shaft 14, and the eccentric ends of two adjacent cams 15 are symmetrical along the axis of the shaking shaft 14.

[0037] Through the above technical solution, during the cleaning process, the shaking shaft 14 rotates following the driving shaft 72, so that the multiple cams 15 shake the net, thereby improving the cleaning efficiency of the attached objects.

[0038] Furthermore, the vertical moving mechanism 8 includes a fixed frame 81, which is fixedly installed in the frame 1, and racks 83 are fixedly installed on the inner walls on both sides of the fixed frame 81. A driven shaft 82 is rotatably installed in the middle of the outer wall of the side of the floating plate 11 away from the cleaning plate 12. The driven shaft 82 is connected to the transmission mechanism 9 through a transmission belt. A half gear 84 is fixedly installed on the end of the driven shaft 82 away from the floating plate 11. The half gear 84 is located in the inner cavity of the fixed frame 81 and meshes with the rack 83.

[0039] Furthermore, the transmission mechanism 9 includes a fixed plate 91, a transmission shaft 92 is rotatably sleeved on the floating plate 11, a transmission belt is sleeved between one end of the transmission shaft 92 and the driven shaft 82, the other end of the transmission shaft 92 is fixedly connected to a rotating wheel 93, the end face of the driving shaft 72 away from the motor 71 is fixedly connected to a rotating drum 94, a limiting ring 95 is fixedly sleeved on the outer wall of the rotating drum 94, guide plates 96 are fixedly installed at both ends of the limiting ring 95, and a guide groove 97 is formed between the two guide plates 96, and a plurality of rollers 98 are installed on the edge of one end of the rotating wheel 93 away from the transmission shaft 92, the rollers 98 are fitted with the limiting ring 95 and the guide plate 96, the limiting ring 95 is a C-shaped structure, the guide plate 96 is an inclined structure, and the plurality of rollers 98 are evenly distributed along the circumferential direction of the rotating wheel 93, the thickness of the limiting ring 95 is equal to the spacing between two adjacent rollers 98, and the width of the guide groove 97 is equal to the diameter of the roller 98.

[0040] Through the above technical solution, the driving shaft 72 and the driven shaft 82 are linked by the transmission mechanism 9. When the driving shaft 72 rotates one circle, the cleaning plate 12 moves horizontally back and forth once. At this time, the rotating drum 94 rotates one circle. When the rotating drum 94 rotates, when the limiting ring 95 is located between the two rollers 98, the rotating wheel 93 does not move. When the guide plate 96 rotates to the roller 98, the roller 98 is pushed by the inclined structure, and the roller 98 moves along the guide groove 97. At this time, the rotating wheel 93 rotates an angle, and the roller 98 slides out of the guide groove 97 and moves to the other side of the limiting ring 95. At this time, the limiting ring 95 limits the roller 98 again. When the driven shaft 82 rotates, the half gear 84 is driven to rotate. The half gear 84 rotates and alternately engages with the racks 83 on both sides of the fixed frame 81. The fixed frame 81 is fixed and does not move. The reverse force of the half gear 84 causes the floating plate 11 to move vertically. As a result, after the cleaning plate 12 reciprocates horizontally for cleaning once, the floating plate 11 is vertically displaced for a distance, thereby cleaning the next section of the net. After a vertical reciprocating cycle, the gripper 6 releases the net and the frame 1 moves to the next area.

[0041] Working principle: the frame 1 sinks into the water, and the lifting propeller 2 controls the lifting and lowering, the moving propeller 3 controls the left and right movement, and the forward propeller 4 controls the distance from the net. The motor 63 drives the rotating shaft 62 to rotate, so that the worm 64 drives the two worm wheels 65 to rotate, so that the clamping rod 66 clamps or releases the net, so as to limit the net in the cleaning area to prevent the net from swaying with the waves. The seawater conductivity sensor and camera detect the conductivity of seawater, the number and thickness of attachments, etc., to determine the pulse voltage amplitude, and the high-voltage pulse discharges in the water to generate cavitation gas. Bubbles are formed, and the cavitation bubble shock wave effect when it is generated and the cavitation jet effect and shock wave effect when it collapse are used to remove the attachments on the net of the net box, so as to achieve the purpose of efficient cleaning. The motor 71 drives the driving shaft 72 to rotate, so that the conveying roller 73 rotates. When the conveying roller 73 rotates, the push-pull groove 75 pushes the slide bar 76, so that the slide block 74 reciprocates along the floating plate 11, so that the cleaning plate 12 performs a horizontal reciprocating external cleaning on the net area fixed by the gripper 6. The driving shaft 72 and the driven shaft 82 are linked through the transmission mechanism 9, and the driving shaft 72 rotates When the cleaning plate 12 makes one circle, the cleaning plate 12 reciprocates horizontally once. At this time, the drum 94 rotates one circle. When the drum 94 rotates, when the limiting ring 95 is located between the two rollers 98, the rotating wheel 93 does not move. When the guide plate 96 rotates to the roller 98, the roller 98 is pushed by the inclined structure, and the roller 98 moves along the guide groove 97. At this time, the rotating wheel 93 rotates an angle, and the roller 98 slides out of the guide groove 97 and moves to the other side of the limiting ring 95. At this time, the limiting ring 95 limits the roller 98 again, so that the drum 94 rotates one circle and the rotating wheel 93 rotates an angle intermittently. For the purpose, the transmission shaft 92 intermittently drives the driven shaft 82 to rotate. When the driven shaft 82 rotates, it drives the half gear 84 to rotate. The half gear 84 rotates to alternately engage the racks 83 on both sides of the fixed frame 81. The fixed frame 81 is fixed, and the reverse force of the half gear 84 causes the floating plate 11 to move vertically. Therefore, after the cleaning plate 12 reciprocates horizontally for cleaning once, the floating plate 11 is vertically displaced for a distance, thereby cleaning the next section of the net. After a vertical reciprocating cycle, the gripper 6 releases the net, and the frame 1 moves to the next area, thereby achieving comprehensive cleaning of the net.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
