Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean recovery equipment, and particularly relates to a novel ocean pollution cleaning device based on bionic technology. BACKGROUND

[0002] During offshore oil development and transportation, oil leakage incidents occur frequently, causing serious threats to the marine ecological environment. A large amount of oil leakage can directly harm seabirds, marine mammals and other marine organisms. Oil contains a large amount of organic and inorganic substances, which can quickly pollute water quality once leaked, hinder the gas exchange between seawater and the atmosphere, and lead to a decrease in the oxygen content of seawater, thereby affecting the entire marine ecosystem.

[0003] Marine floating garbage, also known as marine plastic pollution, is another important reason affecting the marine ecosystem. Nearly 8 million tons of plastic enter the ocean every year, causing damage to the marine ecosystem. The main sources of marine floating garbage include plastic waste on land, fishing activities and maritime transportation. Floating garbage poses a serious threat to marine life, and many marine organisms mistakenly eat plastic, leading to health problems and even death. In addition, floating garbage also destroys habitats and affects fisheries and tourism.

[0004] The problems of existing marine oil leakage cleaning technologies mainly focus on the following aspects: low efficiency: the existing oil spill treatment equipment has low efficiency in dealing with thin oil layers, has a small recovery range, and the equipment is large in size, making it difficult to flexibly respond to different situations; environmental impact: chemical treatment methods may cause secondary pollution to the marine environment, and biological treatment methods have slow degradation speed, making it difficult to respond to sudden oil pollution incidents; equipment complexity: although foreign ship-mounted oil spill recovery systems have high automation, they are expensive, complex and require professional operation, which limits their widespread application.

[0005] There are various methods for cleaning marine floating garbage, but each has some defects, mainly including: physical cleaning equipment: such as trawl nets, buoys, etc. These devices often have difficulty effectively capturing small plastic particles and may accidentally harm marine life; chemical treatment method: using chemical solvents to decompose plastic. Chemical treatment may produce harmful byproducts, leading to secondary pollution and further damage to the ecosystem; manual cleaning: volunteers or professional teams clean the coast and water surface. Manual cleaning is inefficient, difficult to cover a wide ocean, and has high labor and time costs; adsorption technology: using special adsorption materials or equipment. Sometimes it is difficult to selectively remove plastic, which may also adsorb other useful substances; recycling: recycling and reprocessing captured garbage. Recycling facilities are insufficient, and the processing cost is high, and many cleaned garbage still cannot be effectively recycled. SUMMARY

The third connecting piece located on the first support rod 2 is connected with the adjacent third connecting piece located on the third support rod through the elastic rope 4. The plurality of first support rods 2, the plurality of second support rods 3 and the elastic rope 4 form a spider web structure.

The telescopic cylinder drives the sliding rod 11 to move up and down along the sliding groove, so that the sleeve ring slides along the first support rod 2. In this embodiment, the first support rod 2, the second support rod 3 and the sliding rod 11 are all made of stainless steel 306L, which has good corrosion resistance and strength, and the cavity is made of glass fiber composite material, which can ensure that the cavity is light in weight and corrosion resistant.

[0027] In combination Figure 4 and Figure 5 As shown, a plurality of first screen holes 7 are formed on the lower side of the upper part of the sleeve 6 in the circumferential direction, and the first screen hole 7 located at the middle position is adjacent to or coincides with the sea level. A rotating cylinder 9 is arranged in the sleeve 6, bearings are arranged between the inner walls of the sleeve, and the top of the rotating cylinder 9 is lower than the sea level. The upper part of the rotating cylinder 9 is in the shape of a circular tube, the lower part is tapered, a gear is arranged outside the rotating cylinder 9, and a motor is drivingly connected with the rotating cylinder 9 through the gear or worm gear to drive the rotating cylinder 9 to rotate in the sleeve 6. Figure 6 and Figure 7As shown, the rotating cylinder 9 rotates, the convex block 10 on the inner wall makes the sea water inside it produce vortex, thereby generating suction force on the surrounding floating garbage, oil pollution. The upper part of the sleeve 6 is fixed with a baffle 8, the baffle 8 is located above the rotating cylinder 9, and is fixedly connected with the inner wall of the sleeve 6 located on the upper side of the first sieve hole 7. The middle part of the baffle 8 is raised upward, and a plurality of second sieve holes 801 are formed in the edge.

[0028] The bionic sea anemone oil collection mechanism includes a plurality of oil inlet pipes 5 and oil extraction pumps connected with each oil inlet pipe 5. Each oil inlet pipe 5 is provided with a plurality of oil suction holes. The oil extraction pump is fixed in the shell 1 and communicates with the cavity. Each oil inlet pipe 5 is curved and fixed on the shell 1 to extend outward. The upper part of each oil inlet pipe 5 is close to the plane where the top surface of the rotating cylinder 9 is located, which is convenient for absorbing leaked oil. The inner wall of each oil inlet pipe 5 is provided with an oil suction core, which can maximize the removal of marine oil pollution and has low processing cost.

[0029] The novel marine pollution cleaning device is connected with the transport ship through a rope or a pipeline. The novel marine pollution cleaning device is placed on the sea surface where oil is leaked. The controller collects the height and thickness of the oil layer on the sea surface in real time through the oil thickness sensor, and then adjusts the buoyancy by adjusting the ballast water tank to adjust the novel marine pollution cleaning device to the appropriate position, so that the top surface of the rotating cylinder 9 is located in the oil layer. The motor is connected with the gear on the surface of the rotating cylinder 9 through a worm gear or a gear, and drives the rotating cylinder 9 to rotate in the sleeve 6. The rotating cylinder 9 generates vortex in the sea water inside it by the convex block 10 during rotation, and continuously attracts the oil layer on the surrounding sea level and garbage. The oil extraction pump starts to continuously absorb the leaked oil through the oil suction holes on the oil inlet pipe 5 and stores it in the cavity. The Hall sensor is arranged on the oil extraction pump, and the Hall sensor is connected with the controller. The controller detects the rotating speed of the oil extraction pump through the Hall sensor to ensure that the oil extraction pump can work normally and safely, and once the rotating speed of the oil extraction pump is abnormal or the number of damaged oil extraction pumps exceeds the limited number, the controller will stop the operation of the oil extraction pump. The Hall sensor cooperates with the sonar to monitor the oil pollution, garbage, storage capacity, rotating speed and surrounding environment, and plans the path through adaptive control to realize active navigation to the target area and work. The number and density of the oil suction holes near the upper end of each oil inlet pipe 5 gradually increase to improve the oil absorption efficiency.

[0030] The rotating cylinder 9 continuously attracts the oil layer and the garbage gathering process by generating vortex, the garbage in the oil layer will be blocked by the first screen hole 7 on the sleeve 6, and the oil stains will enter the sleeve 6 through the first screen hole 7, and enter the rotating cylinder 9 and the cavity through the second screen hole 801. After running for a period of time, when enough garbage is gathered around the sleeve 6, the controller is stretched upwards through the telescopic cylinder, drives the sliding rod 11 to move upwards along the sliding groove, thereby pushing the sleeve ring to move upwards along the first support rod 2. In the process of moving upwards, the first support rod 2 pulls the adjacent second support rod 3 upwards through the elastic rope 4, so that the first support rod 2 and the second support rod 3 are shrunk in an umbrella shape, and the elastic rope 4 is used to wrap the garbage around the sleeve 6. In the process of wrapping, the first support rod 2, the second support rod 3 and the elastic rope 4 cooperate to lift the garbage upwards, part of the garbage will enter the sleeve 6 from the top of the sleeve 6 for temporary storage, and the amount of stored garbage is increased. When the cleaning device stores a reasonable amount of oil-water mixture and garbage, the staff on the ship can take back the cleaning device to the ship for cleaning, emptying, and then placing it on the sea level again for repeated use.
