Description

Technical Field

[0001] The invention relates to the technical field of marine recycling equipment, and in particular to a novel marine pollution cleaning device based on bionic technology. Background Art

[0002] During the development and transportation of offshore oil, oil spills frequently occur, posing a serious threat to the marine ecological environment. Large amounts of crude oil spills can cause direct harm to seabirds, marine mammals, and other marine life. Crude oil contains a large amount of organic and inorganic matter, which, once leaked, will quickly pollute water quality, hinder gas exchange between seawater and the atmosphere, and cause a decrease in seawater oxygen content, which in turn affects the entire marine ecosystem.

[0003] Floating garbage at sea is another important factor affecting the marine ecosystem. Floating garbage at sea is also known as marine plastic pollution. Nearly 8 million tons of plastic enter the ocean every year, causing damage to the marine ecosystem. The main sources of floating garbage at sea include plastic waste on land, fishing activities and maritime transportation. Floating garbage poses a serious threat to marine life. Many marine life mistakenly ingest plastic, leading to health problems or even death. In addition, floating garbage can also destroy habitats and affect fisheries and tourism.

[0004] The problems of existing marine oil spill cleaning technologies are mainly concentrated in the following aspects: low efficiency: the existing oil spill treatment equipment has low efficiency when facing thin oil layers, a small recovery range, and a large 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 a slow degradation rate and are difficult to respond to sudden oil pollution incidents; equipment complexity: although foreign ship oil spill recovery systems have a high degree of automation, they are expensive, complex systems, and require strong professional operations, which limits their widespread application.

[0005] There are many methods for cleaning floating garbage at sea, but each has some defects, mainly including: physical cleaning equipment: such as trawls, floats, etc. These devices often have difficulty in effectively capturing tiny plastic particles and may cause accidental harm to marine life; chemical treatment method: using chemical solvents to decompose plastics. Chemical treatment may produce harmful byproducts, leading to secondary pollution and further damage to the ecosystem; manual cleaning: volunteers or professional teams conduct coastal and surface cleaning. Manual cleaning is inefficient, difficult to cover the vast ocean, and has high manpower and time costs; adsorption technology: using special adsorption materials or equipment. Sometimes it is difficult to selectively remove plastics, and other useful substances may be adsorbed at the same time; recycling and reuse: the caught garbage is recycled and reprocessed. Recycling facilities are insufficient and the processing costs are high, so a lot of the garbage cleaned up still cannot be effectively recycled. Summary of the invention

[0006] In view of the above-mentioned problems that the cleaning and recovery equipment is complex in structure, has low cleaning efficiency, and is easy to pollute the marine environment again when cleaning up marine oil leaks and floating garbage at sea, the present invention provides a new marine pollution cleaning device based on bionic technology.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: A new type of marine pollution cleaning device based on bionic technology includes a shell, a bionic spider web garbage filtering mechanism and a bionic sea anemone oil collection mechanism, wherein the shell has a cavity, and the bionic spider web garbage filtering mechanism and the bionic sea anemone oil collection mechanism are arranged on the shell. The bionic spider web garbage filtering mechanism includes a sleeve, a support rod, a sliding rod and a telescopic cylinder, wherein a plurality of the support rods are arranged along the circumference of the sleeve and are rotatably connected to the sleeve, and the adjacent support rods are connected by a plurality of elastic ropes, one end of the sliding rod slides along the support rod, and the other end is connected to the telescopic cylinder, and the telescopic cylinder drives each of the support rods to achieve a posture change of extension or relaxation through extension. The bionic sea anemone oil collection mechanism includes a plurality of oil inlet pipes, each of which is provided with a plurality of oil suction holes, each of which protrudes from the shell and extends outward, and the oil inlet pipe is connected to an oil pump.

[0008] Furthermore, the sleeve is fixed on the top of the shell and communicated with the cavity, the upper part of the sleeve protrudes from the shell, a protrusion is provided on the outer wall of the sleeve, and the end of each support rod is rotatably connected to the protrusion.

[0009] Furthermore, the support rod is divided into a first support rod and a second support rod, the first support rod and the second support rod are arranged alternately, and the ends of several sliding rods are rotatably connected with rings, and the rings are correspondingly mounted on the first support rod and slide along the first support rod.

[0010] Furthermore, the telescopic cylinder is fixed at the lower part of the sleeve, and a plurality of sliding grooves adapted to the sliding rod are opened on the outer wall of the sleeve. The telescopic cylinder drives the sliding rod to move up and down along the sliding grooves, thereby making the collar slide along the first support rod.

[0011] Furthermore, a plurality of first sieve holes are provided on the upper portion of the sleeve along the circumferential direction, and a rotating cylinder body is arranged in the sleeve, and the rotating cylinder body rotates under the drive of a motor.

[0024] The present invention discloses a novel marine pollution cleaning device based on bionic technology. An implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1As shown, the new marine pollution cleaning device includes a shell 1, a bionic spider web garbage filtering mechanism, a bionic sea anemone oil collection mechanism, a ballast water tank, a controller and a number of thrusters. The shell 1 has a cavity for accommodating oil. The ballast water tank is arc-shaped and arranged in the shell 1. The ballast water tank uses the Archimedes principle to adjust the buoyancy to achieve diving and floating. In this embodiment, the ballast water tank adopts reinforced glass fiber composite material to ensure light weight and corrosion resistance. The controller is respectively connected to the bionic spider web filtering mechanism, the bionic sea anemone oil collection mechanism and a number of thrusters. The controller is also connected to a sonar and an oil layer thickness sensor, and a number of thrusters are fixed on the outer wall of the shell 1. The bionic spider web garbage filtering mechanism and the bionic sea anemone oil collection mechanism are arranged on the shell 1.

[0026] Combination Figure 2 and Figure 3As shown, the bionic spider web garbage filtering mechanism includes a sleeve 6, a support rod, a sliding rod 11 and a telescopic cylinder. The sleeve 6 is fixed on the top of the shell 1 and is connected to the cavity. The upper part of the sleeve 6 protrudes from the shell 1, and a protruding edge is provided on the outer wall of the sleeve 6 and adjacent to the connection position with the shell 1. Several support rods are evenly arranged along the circumference of the sleeve 6, and the protruding edge has several protruding hinge seats, and the left and right sides of the lower end of each support rod are rotatably connected with the adjacent hinge seats. Each support rod is divided into a first support rod 2 and a second support rod 3, and the first support rod 2 and the second support rod 3 are arranged alternately. Several sliding rods 11 are correspondingly connected to the first support rod 2, and the upper end of the sliding rod 11 is hinged with a collar, which is adapted to be arranged on the first support rod 2 and slides along the first support rod 2. Several connecting members are fixedly connected to each support rod, and the connecting members are divided into a first connecting member, a second connecting member and a third connecting member. The first support rod 2 is sequentially arranged with a collar, a second connector and a third connector from the inside to the outside, and the second support rod 3 is sequentially arranged with a first connector, a second connector and a third connector from the inside to the outside. The collar on the first support rod 2 is connected to the adjacent first connector on the second support rod 3 by an elastic rope 4, and the elastic rope 4 has elastic force. The second connector on the first support rod 2 is connected to the adjacent second connector on the second support rod 3 by an elastic rope 4. The third connector on the first support rod 2 is connected to the adjacent third connector on the third support rod by an elastic rope 4. A plurality of first support rods 2, a plurality of second support rods 3 and the elastic rope 4 form a spider web structure. The telescopic cylinder is fixed to the lower part of the sleeve 6, and a plurality of slide grooves adapted to the sliding rod 11 are provided on the outer wall of the lower part of the sleeve 6. The lower end of the sliding rod 11 is arranged in the slide groove and fixedly connected to the telescopic cylinder. The telescopic cylinder drives the sliding rod 11 to move up and down along the slide groove, so that the collar 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 the light weight and corrosion resistance of the cavity.

[0027] Combination Figure 4 and Figure 5 As shown, a plurality of first sieve holes 7 are provided on the lower side of the upper part of the sleeve 6 along the circumferential direction, and the first sieve hole 7 located in the middle is close to or coincides with the sea level. A rotating cylinder body 9 is provided inside the sleeve 6, and a bearing is provided between the rotating cylinder body 9 and the inner wall of the sleeve, and the top of the rotating cylinder body 9 is below the sea level. The upper part of the rotating cylinder body 9 is in the shape of a circular tube, and the lower part is narrowed to be conical. Gears are provided outside the rotating cylinder body 9, and the motor is connected to the rotating cylinder body 9 through gears or worm gears, driving the rotating cylinder body 9 to rotate inside the sleeve 6. Figure 6 and Figure 7As shown, during the rotation of the rotating cylinder 9, the convex blocks 10 on the inner wall are used to generate a vortex in the seawater inside, thereby generating suction for the garbage and oil floating around. A partition 8 is fixed inside the upper part of the sleeve 6. The partition 8 is located above the rotating cylinder 9 and is fixedly connected to the inner wall of the sleeve 6 located on the upper side of the first sieve hole 7. The middle part of the partition 8 bulges upward, and a plurality of second sieve holes are opened on the edge.

[0028] The bionic sea anemone oil collection mechanism includes a plurality of oil inlet pipes 5 and an oil pump correspondingly connected to each oil inlet pipe 5. Each oil inlet pipe 5 is provided with a plurality of oil suction holes. The oil pump is fixed in the shell 1 and communicated 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 body 9 is located, so as to absorb the leaked oil. An oil absorption core is provided on the inner wall of each oil inlet pipe 5, which can maximize the removal of marine oil pollution with low processing cost.

[0029] The new marine pollution cleaning device is connected to the transport ship through a rope or a pipeline, and the new marine pollution cleaning device is placed on the sea surface where the oil is leaking. The controller collects the height and thickness of the sea surface oil layer in real time through the oil thickness sensor, and then adjusts the buoyancy by adjusting the ballast water tank, and adjusts the new marine pollution cleaning device to a suitable position so that the top surface of the rotating cylinder 9 is located in the oil layer. The motor is connected to the gear transmission 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. During the rotation of the rotating cylinder 9, the convex block 10 is used to make the seawater inside it generate a vortex, which continuously attracts the oil layer and garbage on the surrounding sea surface. The oil pump starts to continuously absorb the leaked oil through the oil suction hole on the oil inlet pipe 5 and store it in the cavity. A Hall sensor is provided on the oil pump, and the Hall sensor is connected to the controller. The controller detects the speed of the oil pump through the Hall sensor to ensure that the oil pump can work normally and safely, and once the speed of the oil pump is abnormal or the number of damaged oil pumps exceeds the specified number, the controller will stop the operation of the oil pump. The Hall sensor cooperates with the sonar to monitor oil, garbage, storage volume, rotation speed and surrounding environment, and plans the route through adaptive control, so as 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 are gradually increased to improve the oil suction efficiency. In this embodiment, the oil inlet pipe 5 adopts organic polymer fiber, such as polypropylene fiber, alkyl ethylene polymer fiber, etc., which has hydrophobic and oleophilic properties and can efficiently absorb oil.

[0030] In the process of the rotating cylinder body 9 continuously attracting the oil layer and garbage to gather by generating a vortex, the garbage in the oil layer will be blocked by the first sieve holes 7 on the sleeve 6, while the oil will enter the sleeve 6 through the first sieve holes 7, and enter the rotating cylinder body 9 and the cavity through the second sieve holes. After running for a period of time, when enough garbage gathers around the sleeve 6, the controller extends upward through the telescopic cylinders, driving the sliding rod 11 to move upward along the slide groove, thereby pushing the collar to move upward along the first support rod 2. In the process of each first support rod 2 moving upward, the adjacent second support rod 3 is pulled upward by the elastic rope 4, so that the first support rods 2 and the second support rods 3 shrink in an umbrella shape, and the garbage around the sleeve 6 is wrapped by the elastic rope 4. 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 upward, and some of the garbage will enter the sleeve 6 from the top of the sleeve 6 for temporary storage, thereby increasing the amount of stored garbage. When the cleaning device has stored a suitable amount of oil-water mixture and garbage, the crew on board the ship can retrieve the cleaning device to the ship via a rope for cleaning and emptying, and then place it back on the sea surface for reuse.

[0031] The present invention is highly efficient: through vortex suction and multi-layer oil suction pipe design, the oil recovery efficiency is significantly improved, especially when the oil layer is thin; environmentally friendly: the use of microbial degradation and high-performance composite materials reduces secondary pollution to the environment and meets the requirements of sustainable development; multifunctional: the present invention can not only treat oil pollution, but also recycle marine garbage, with dual functions, and adapt to a variety of marine environments; flexibility: the compressible ballast water tank design enables the device to be flexibly operated under different water conditions and has strong adaptability; economical: through optimized design and material selection, energy consumption and operating costs are reduced, with a high cost performance.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
