The reel 3 is installed on the hull 1, the upper end of the cable 4 is reeled on the reel 3, multiple sonar modules 5 are evenly installed on the cable 4, and multiple buoyancy boxes 6 are installed on the collection box 2. The outer surface of the collection box 2 is covered with a film, and a water inlet is provided at one end of the collection box 2 facing the hull 1. Multiple filter screens 7 are installed laterally inside the collection box 2. The multiple filter screens 7 are arranged in sequence from the inlet of the collection box 2 to the rear, and the mesh size of the multiple filter screens 7 gradually decreases. The collection box 2 rotates on the end near the water inlet. A rudder plate 8 is installed, and the rudder plate 8 is arranged vertically to the collecting box 2. One end of the push rod 9 is rotatably connected to the collecting box 2, and the other end of the push rod 9 is rotatably connected to the rudder plate 8; it also includes a counterweight 10 and a tail fin 11, the counterweight 10 is installed at the lower end of the cable 4, and the rear of the counterweight 10 is installed with the tail fin 11; it also includes a pulley 12, a pressure sensor 13 and a pulley 2 14, the pulley 12 is rotatably installed on the hull 1, the pressure sensor 13 is installed on the hull 1, the end of the pressure sensor 13 is rotatably installed with the pulley 2 14, the pulley 12 and the pulley 2 14 rollingly support the cable 4; it also includes a ranging head 15, the ranging head 15 is installed on the hull 1, the probe of the ranging head 15 is aligned with the cable 4, and the ranging head 15 detects the length of the released cable 4.

[0031] During operation, the hull 1 sails on the sea surface, and the amount of water injected into the multiple buoyancy boxes 6 is adjusted so that the collection box 2 can be suspended in the seawater. The collection box 2 is equipped with a water depth sensor to determine the depth of the collection box 2. The reel 3 releases the cable 4 into the seawater, and the length of the released cable 4 is detected by the ranging head 15, so that multiple sonar modules 5 are arranged in the seawater following the cable 4. The gravity of the counterweight block 10 drops the cable 4 downward, so that the cable 4 remains vertical as much as possible, so that multiple sonar modules 5 follow the cable 4 and are arranged in different water layers of the seawater from top to bottom.

When the rod 24 reaches the front end of the net bag 23, the waterproof motor 2 32 drives the bidirectional screw 31 to rotate, and the bidirectional screw 31 drives the two threaded sliders 30 to move relative to each other, so that the multiple support rods 33 push the two guide rods 24 backward, so that the two guide rods 24 extend into the net bag 23 to compact the garbage therein, and at the same time, the two rear guide rods 34 drive the two rear scrapers 35 to scrape the rear surfaces of the two filter screens 7. Finally, the buoyancy of the multiple floats 6 is adjusted to make the collection box 2 half submerged in the sea. At this time, the collection box 2 can collect garbage floating on the sea surface.

[0039] The main functions achieved by the present invention are:

[0040] 1. It has the structure and function of detecting garbage under the sea surface, and can efficiently collect garbage suspended under the sea surface with relatively few limitations;

[0041] 2. Ability to locate the suspended garbage water layer;

[0042] 3. It can clean the filter and compact the garbage in the net bag;

[0043] 4. The collection box 2 can be folded for easy transportation.

[0044] The installation method, connection method or setting method of the marine garbage collection ship of the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented; the hull 1, collection box 2, reel 3, cable 4, sonar module 5, buoyancy box 6, filter screen 7, push rod 9, counterweight 10, tail wing 11, pulley 12, pressure sensor 13, pulley 2 14, ranging head 15, water pump 22, net bag 23, scraper 1 25, annular rope 26, pulley 3 27, waterproof motor 28, active pulley 29, threaded slider 30, bidirectional screw 31, waterproof motor 2 32, and rear scraper 35 of the marine garbage collection ship of the present invention are purchased on the market, and technicians in this industry only need to install and operate them according to the accompanying instruction manual, without the need for technical personnel in this field to make creative labor.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
