[0048] like Figure 1-8 As shown, a nuclear power plant water intake interception net garbage removal system in this embodiment includes a floating discharge device 1, a mobile suction device 2, a garbage lifting device 3 and a trestle device 4. When the garbage in the net bag 5 is full of garbage, the mobile suction device 2 is connected to the tail of one of the net bags 5 and the garbage in the net bag 5 is sucked out. Subsequently, the mobile suction device 2 moves to the next net bag 5 and sucks out the garbage in the net bag 5, that is, the garbage in each net bag 5 can be sucked out in turn, and the sucked-out garbage is transported to the shore garbage disposal through the garbage lifting device 3. The floating discharge device 1 is used to provide an operating basis for the mobile suction device 2, and the floating discharge device 1 is connected to the shore through the trestle device 4. In this way, there is no need to lift the net bag 5 for garbage removal, which reduces the operation and maintenance workload of on-site garbage removal and improves the efficiency of garbage cleaning.

[0049] The floating device 1 includes a floating main body 12 which is formed by sequentially splicing a plurality of floating modules 11. The garbage at the tail of the net bag 5 can be cleaned on the floating main body 12 without the cooperation of a surface vessel. The sustainability of the interception function of the interception net can be ensured when marine organisms suddenly break out, and the rapid transportation of garbage is achieved with high cleaning efficiency. When a single floating module 11 is damaged, it can be quickly replaced. An anchor chain 13 is provided on the upstream and downstream sides of each floating module 11. One end of the anchor chain 13 is fixedly arranged on the floating main body 12, and the other end of the anchor chain 13 is fixedly arranged on the floating main body 12. An anchor 14 is provided. The anchor 14 is a delta anchor, which is connected to the anchor chain 13 via a shackle. The delta anchor weighs 1 ton and uses a delta anchor for anchoring, which can provide greater anchoring force. Anchor chains 13 and anchors 14 are provided in the upstream and downstream directions of the floating row body 12 to improve the stability of the floating row body 12. An adjustment mechanism 15 is provided at the bottom of each floating row module 11. The adjustment mechanism 15 is used to adjust the level of the floating row body 12 to reduce the degree of inclination of the pedal 11.1 caused by waves, further improving the stability of the floating row body 12.

[0050] The floating row module 11 includes a horizontally arranged pedal 11.1, the bottom of which is bolted to a bracket 11.2, and the top of which is fixedly provided with a railing 11.3. The bracket 11.2 is provided with multiple buoyancy tubes 11.4. The buoyancy tubes 11.4 are made of low-pressure polyethylene, have an outer diameter of 500mm, and a wall thickness of 23.9mm. The buoyancy tubes 11.4 are connected in series to form a whole, and the buoyancy tubes 11.4 provide buoyancy to enable the pedal 11.1 to float.

[0051] The regulating mechanism 15 includes a regulating tube 15.1 fixedly arranged horizontally at the bottom of the bracket 11.2. The regulating tube is arranged opposite to the bracket 11.2. The two ends of the regulating tube 15.1 are respectively arranged in the upstream and downstream directions. Air bags 15.2 are provided at both ends of the regulating tube 15.1. Two regulating plates 15.3 are arranged at intervals in the regulating tube 15.1. The regulating plates 15.3 are slidably and sealedly connected to the regulating tube 15.1. A moving component 15.4 is provided between the two regulating plates 15.3. The moving component 15.4 drives the two regulating plates 15.3 to move synchronously in the regulating tube 15.1 along the length direction of the regulating tube 15.1. When waves appear, the waves move from the upstream of the bracket 11.2 to the downstream of the bracket 11.2 and cause the bracket 11.2 to tilt, that is, the floating row module 11 is tilted. When the tilt reaches a certain level, the adjusting plate 15.3 is moved inwardly within the adjusting tube 15.1 by the moving assembly 15.4, and the air in the airbag 15.2 at the high tilt position is transported into the adjusting tube 15.1, causing the airbag 15.2 to shrink. The air in the adjusting tube 15.1 is then transported into the other airbag 15.2, causing it to expand. The buoyancy generated by the expanding airbag 15.2 is greater than that of the shrinking airbag 15.2. That is, the buoyancy on the bracket 11.2 at the point where the airbag 15.2 is expanded is greater than that at the point where the airbag 15.2 shrinks. The buoyancy difference generates a buoyancy that lifts the bracket 11.2 and offsets the tilt caused by the waves pushing up the bracket 11.2. That is, the floating row module 11 can always be kept within a certain tilt angle, avoiding an excessive tilt angle that affects stability.

[0052] The moving assembly 15.4 includes a screw 15.41, one end of which is driven by an adjusting motor 15.42. A slider 15.43 is threadedly connected to the screw 15.41. A transmission rod 15.44 is fixedly provided on the top and bottom of the slider 15.43. The transmission rod 15.44 and the screw 15.41 are parallel to the adjusting tube 15.1. The two ends of the screw 15.41 are respectively fixed on two adjusting plates 15.3. When the adjusting motor 15.42 drives the screw 15.41 to rotate, the slider 15.43 moves axially along the adjusting tube 15.1 on the screw 15.41. The movement of the slider 15.43 drives the two adjusting plates 15.3 to move synchronously through the transmission rod 15.44.

[0053] The bracket 11.2 is provided with a level sensor 15.45 and a PLC 15.46. The level sensor 15.45 and the adjustment motor 15.42 are both connected to the PLC 15.46. The level sensor 15.45 detects the levelness and transmits the data to the PLC 15.46. After calculation, the PLC 15.46 causes the adjustment motor 15.42 to drive the lead screw 15.41 to start, so that the adjustment plate 15.3 moves the corresponding distance according to the levelness, thereby realizing intelligence.

[0054] The mobile suction device 2 includes a mobile frame 21, and a suction mechanism 22 is provided on the top of the mobile frame 21. The suction mechanism 22 is used to extract garbage from the net bag 5. The mobile frame 21 is provided with a displacement mechanism 23. The displacement mechanism 23 is used to drive the mobile frame 21 to move on the floating row body 12, so that the mobile suction device 2 can extract garbage from different net bags 5. A collection mechanism 24 is provided on one side of the mobile frame 21. The collection mechanism 24 is used to collect garbage extracted from the net bag 5.

[0055] The suction mechanism 22 includes a suction pump 22.1, which is provided with a feed pipe 22.3 and a discharge pipe 22.3. The suction pump 22.1 is driven by a power unit 22.4. The power unit 22.4 starts the suction pump 22.1, so that the feed pipe 22.3 draws the garbage in the net bag 5 and discharges it from the discharge pipe 22.3 to the collection mechanism 24.

[0056] The power unit 22.4 includes a diesel engine 22.41, which is connected to the suction pump 22.1 via a clutch 22.42. A fuel tank 22.43 is connected to one side of the diesel engine 22.41. When the diesel engine 22.41 is started, the suction pump 22.1 is driven to operate via the clutch 22.42, and the fuel tank 22.43 provides diesel to the diesel engine 22.41. A radiator 22.44 is provided on the diesel engine 22.41 to improve the heat dissipation effect of the diesel engine 22.41.

[0057] The displacement mechanism 23 includes two sets of tracks 23.1 arranged side by side at the bottom of the mobile frame 21. The mobile frame 21 is provided with a battery pack 23.2. The battery pack 23.2 provides the electric energy required for the tracks 23.1 to rotate. During the rotation of the tracks 23.1, the mobile frame 21 is driven to move.

[0058] The collecting mechanism 24 includes a movable frame 24.1 disposed on one side of the movable frame 21. A roller 24.2 is provided at the bottom of the movable frame 24.1. The top and one side of the movable frame 24.1 are open. A drain basket 24.3 and a vibrating assembly 24.4 are arranged above and below the movable frame 24.1. The vibrating assembly 24.4 is used to vibrate the drain basket 24.3 up and down. The movement of the movable frame 21 drives the movable frame 24.1 to move synchronously. When the garbage is transported from the top of the movable frame 24.1 to the drain basket 24.3, the moisture in the garbage is discharged from the drain basket 24.3 into the movable frame 24.1, and then the movable frame 24. 1 is discharged through the opening on one side, thereby realizing solid-liquid separation of the garbage in the drain basket 24.3, reducing the weight of the garbage and facilitating garbage transportation. The vibration component 24.4 makes the garbage in the drain basket 24.3 vibrate back and forth. Under the action of inertia, it is convenient to discharge the water in the garbage and improve the solid-liquid separation efficiency of the garbage. In addition, the vibration can compact the garbage in the drain basket 24.3, reduce the gap between the garbage, increase the amount of garbage stored in the drain basket 24.3, and improve the garbage transportation efficiency. When the garbage in the drain basket 24.3 is full, the drain basket 24.3 is taken out and transported to the garbage disposal site on the shore through the garbage lifting device 3, and then the garbage can be dumped out.

[0059] The vibration assembly 24.4 includes a lifting plate 24.41 and an electromagnet 24.42 arranged up and down. The drain basket 24.3 is placed on the top of the lifting plate 24.41. The electromagnet 24.42 is fixedly arranged at the bottom of the movable frame 24.1. Three lifting units 24.43 are provided at the bottom of the lifting plate 24.41. The three lifting units 24.43 are evenly distributed circumferentially with the electromagnet 24.42 as the center. The magnetic field generated by the reciprocating power supply of the electromagnet 24.42 controls the lifting unit 24.43 to drive the lifting plate 24.41 to move up and down, thereby causing the drain basket 24.3 to move up and down.

[0060] The lifting unit 24.43 includes a support block 24.431 fixedly arranged at the bottom of the moving frame 24.1, the bottom of the support block 24.431 abuts against the bottom of the lifting plate 24.41, and a moving rod 24.432 is passed through the support block 24.431. An adsorption block 24.433 is fixedly arranged at one end of the moving rod 24.432 close to the electromagnet 24.42, and the other end of the moving rod 24.432 is hinged to the bottom of the lifting plate 24.41 through a connecting rod 24.434. The connecting rod 24.434 is tilted, and a spring 24.435 is provided on the lifting plate 24.41. One end of the spring 24.435 is fixedly arranged at the bottom of the lifting plate 24.41. The other end of 35 is fixedly arranged at the bottom of the moving frame 24.1, and the electromagnet 24.42 is energized reciprocatingly. When the electromagnet 24.42 is energized, the adsorption block 24.433 moves toward the direction close to the electromagnet 24.42, and drives the moving rod 24.432 to move synchronously. The movement of the moving rod 24.432 drives the lifting plate 24.41 to rise through the connecting rod 24.434 and stretches the spring 24.435. When the electromagnet 24.42 is de-energized, the elastic action of the spring 24.435 causes the lifting plate 24.41 to move downward to achieve reset, and the connecting rod 24.434 causes the moving rod 24.432 and the adsorption block 24.433 to move in the opposite direction to achieve reset, and so on and so forth, thereby achieving the reciprocating lifting of the lifting plate 24.41.

[0061] A blocking rod 24.5 is fixedly provided at the opening on one side of the movable frame 24.1. The function of the blocking rod 24.5 is to block the drain basket 24.3 and prevent the drain basket 24.3 from sliding off the movable frame 24.1.

[0062] A garbage collection method comprises the following steps:

[0063] S1, the movable frame 21 is moved to the net bag 5 by the displacement mechanism 23;

[0064] The displacement mechanism 23 includes two sets of crawlers 23.1 arranged side by side at the bottom of the mobile frame 21. The mobile frame 21 is provided with a battery pack 23.2.

[0065] S2, extracting the garbage in the net bag 5 through the suction mechanism 22;

[0066] The suction mechanism 22 includes a suction pump 22.1, which is provided with a feed pipe 22.3 and a discharge pipe 22.3. The suction pump 22.1 is driven by a power unit 22.4. The power unit 22.4 activates the suction pump 22.1, thereby causing the feed pipe 22.3 to extract the garbage in the net bag 5 and discharge it from the discharge pipe 22.3 to the collection mechanism 24.

[0067] The power unit 22.4 includes a diesel engine 22.41, which is connected to the suction pump 22.1 via a clutch 22.42. A fuel tank 22.43 is connected to one side of the diesel engine 22.41.

The top and one side of the movable frame 24.1 are open. A drain basket 24.3 and a vibrating assembly 24.4 are arranged above and below the movable frame 24.1. The vibrating assembly 24.4 is used to vibrate the drain basket 24.3 up and down. The movement of the movable frame 21 drives the movable frame 24.1 to move synchronously. When the garbage is transported from the top of the movable frame 24.1 to the drain basket 24.3, the moisture in the garbage is discharged from the drain basket 24.3 into the movable frame 24.1, and then the movable frame 24. 1, the opening on one side is used for discharge, so as to realize solid-liquid separation of the garbage in the drain basket 24.3, reduce the weight of the garbage, and facilitate garbage transportation. The vibration component 24.4 causes the garbage in the drain basket 24.3 to vibrate up and down. Under the action of inertia, it is easy to discharge water from the garbage, thereby improving the efficiency of solid-liquid separation of the garbage. In addition, the vibration can compact the garbage in the drain basket 24.3, reduce the gap between the garbage, increase the amount of garbage stored in the drain basket 24.3, and improve the efficiency of garbage transportation. When the drain basket 24.3 is full of garbage, the drain basket 24.3 is taken out and transported to the garbage disposal site on the shore through the garbage lifting device 3, and then the garbage can be dumped out.

[0070] The vibration assembly 24.4 includes a lifting plate 24.41 and an electromagnet 24.42 arranged vertically. The drain basket 24.3 is placed on top of the lifting plate 24.41. The electromagnet 24.42 is fixedly arranged at the bottom of the movable frame 24.1. Three lifting units 24.43 are provided at the bottom of the lifting plate 24.41. The three lifting units 24.43 are evenly distributed circumferentially around the electromagnet 24.42. The magnetic field generated by the reciprocating power supply of the electromagnet 24.42 controls the lifting units 24.43 to drive the lifting plate 24.41 to move up and down, thereby causing the drain basket 24.3 to move up and down.

[0071] The lifting unit 24.43 includes a support block 24.431 fixedly arranged at the bottom of the moving frame 24.1, the bottom of the support block 24.431 abuts against the bottom of the lifting plate 24.41, and a moving rod 24.432 is passed through the support block 24.431.

The connecting rod 24.434 is tilted, and a spring 24.435 is provided on the lifting plate 24.41. One end of the spring 24.435 is fixedly arranged at the bottom of the lifting plate 24.41. The other end of 35 is fixedly arranged at the bottom of the moving frame 24.1, and the electromagnet 24.42 is energized reciprocatingly. When the electromagnet 24.42 is energized, the adsorption block 24.433 moves toward the direction close to the electromagnet 24.42, and drives the moving rod 24.432 to move synchronously. The movement of the moving rod 24.432 drives the lifting plate 24.41 to rise through the connecting rod 24.434, and stretches the spring 24.435. When the electromagnet 24.42 is de-energized, the elastic action of the spring 24.435 causes the lifting plate 24.41 to move downward to achieve reset, and the connecting rod 24.434 causes the moving rod 24.432 and the adsorption block 24.433 to move in the opposite direction to achieve reset, and so on and so forth, thereby achieving the reciprocating lifting of the lifting plate 24.41;
