DETAILED DESCRIPTION

[0017] See also Figure 1 , which is a schematic diagram of the overall structure of this embodiment. The device includes a mobile mechanism 10 and a recovery mechanism 20 arranged on the mobile mechanism 10. The recovery mechanism 20 includes an oil boom and an absorption component 30 connected to the mobile mechanism 10. In this embodiment, the mobile mechanism 10 can be a hull. The driving device is arranged at the tail of the device. The acceptable infrared rays are generated by remote control of the staff. After the infrared sensor receives the external infrared signal, it will transmit an electrical signal to the PLC worker after the flashing. The motor receives the signal and starts the device to drive the device to sail to the oil spill area; the hull adopts a double hull design to reduce the wave resistance, ensuring that the stability of the device can be controlled when there are wind and waves. At the same time, it can quickly reach the oil spill site during work, avoiding the situation that the oil spill recovery device cannot work normally in severe sea conditions. The oil spill boom includes a retractable component 21 and an inflatable rubber fence 22. The mechanical fence is adjusted by remote control to retract and retract to control the area of ​​the enclosed sea area, thereby achieving the effect of quickly fixing the spilled oil at a fixed point on the sponge. Then the recovery of the offshore oil spill is completed through the work of the recovery mechanism 20.

[0018] Furthermore, the recovery mechanism 20 also includes a storage chamber disposed inside the mobile mechanism 10. A connecting pipe 23 is disposed between the mobile mechanism 10 and the absorption assembly 30. The storage chamber is connected to the absorption assembly 30 through the connecting pipe 23. In order to increase the mobility of the recovered oil inside the connecting pipe 23, a heating column and a heat-insulating layer are added to the surface of the connecting pipe 23. The heating column can convert electrical energy into heat energy. In order to reduce energy consumption and improve energy utilization, a heat-insulating layer is added to the outside of the oil pipe to reduce heat loss. Thus, the oil spill inside the connecting pipe 23 is increased or moved by utilizing the property that the viscosity of the oil spill decreases under the condition of increased temperature.

[0019] like Figure 2 and Figure 3 As shown, the absorption assembly 30 includes a separation cylinder 31 designed to communicate with the connection pipe 23, a screw-in portion 32 is arranged above the separation cylinder 31, a rotating ring 321 is rotatably connected to the inside of the screw-in portion 32, a paddle-type scraper 322 is fixedly installed on the outside of the rotating ring 321, and an inlet 323 distributed in the circumferential direction is opened on the screw-in portion 32. In this embodiment, the rotation of the rotating ring 321 can drive the paddle-type scraper 322 evenly distributed on the periphery to rotate, and the paddle-type scraper 322 can be used to screw the floating oil spill on the sea into the separation cylinder 31 through the inlet 323; on the other hand, the paddle-type scraper 322 includes an arc surface a and a flat surface b, and the area of ​​the arc surface a gradually decreases from the inside to the outside along the radial direction of the rotating ring 321; and the flat surface b has two connected in a mutually perpendicular manner. When the rotating ring 321 rotates and drives the paddle-type scraper 322 to run synchronously, the oil spill on the sea surface will be scraped due to the existence of the arc surface a. During the scraping process, a part of the arc surface a is below the sea level (such as Figure 7 As shown in FIG. 1 , a part of the oil spill is above the sea level. With the driving force, the arc surface a drives the oil spill part, and the oil spill will flow inward into the absorption component 30 along the surface of the arc surface a, while most of the seawater will flow along the bottom of the arc surface a, and part of it will also enter the absorption component 30. Thus, the rapid recovery effect of the oil spill is achieved.

[0020] Moreover, during this process, due to the shape design of the paddle scraper 322, a certain vortex will be generated during the rotation, which accelerates the seawater and oil mixture to enter the separation cylinder 31, so that the oil mixture enters the separation cylinder 31 with initial power.

[0021] like Figure 4 and Figure 5As shown, a driving assembly 40 is provided on the screw-in portion 32, and the driving assembly 40 includes a waterproof driving member fixedly mounted on the separation cylinder 31, and the driving member can be a motor; a driving gear 41 is fixedly mounted on the output end of the driving member, and a driven gear ring 42 is sleeved on the outer side of the separation cylinder 31 and is rotatably connected and meshed with the driving gear 41, and the driven gear ring 42 is fixedly connected to a connecting ring 43, and the connecting ring 43 is rotatably connected to the separation cylinder 31, and the upper part of the connecting ring 43 is fixedly connected to the rotating ring 321 through a fixed ring. In this embodiment, the rotation of the connecting ring 43 is driven by the rotation of the driving member, and finally the rotating ring 321 is driven to rotate.

[0022] like Figure 6 As shown, the separation cylinder 31 includes an upper shell 311 and a lower shell 312, the upper shell 311 and the lower shell 312 are fixedly connected, and a mounting groove for the screw-in portion 32 to be installed is formed at the connection, and the upper shell 311 is fixedly connected to the moving mechanism 10 through a connecting rod. A plurality of liquid inlets 313 for the mixed liquid to enter are provided in the circumferential direction on the upper shell 311. In this embodiment, the mixed liquid of the oil spill and seawater is screwed into the absorption assembly 30 through the screw-in portion 32. Because of the mounting groove formed between the upper shell 311 and the lower shell 312, the mixed liquid can only enter the separation cylinder 31 from the liquid inlet 313, that is, from the top of the separation cylinder 31.

[0023] Furthermore, the upper shell 311 is shaped to be wide at the top and narrow at the bottom. The upper shell 311 is provided with a liquid inlet 313 for the mixed liquid to enter. After the mixed liquid enters the wide part of the upper shell 311 from the liquid inlet 313, it will flow to the narrow part under the action of force. The narrow part is provided with a guide platform 314. The path of the guide platform 314 is a spiral design, and the direction of the spiral is from top to bottom. In this embodiment, when the mixed liquid flows from the wide part to the narrow part, it will generate a rotating force under the action of the guide platform 314 when passing through the guide platform 314. The mixed liquid with the rotating force will generate a vortex. The mixed liquid in a rotating state will continue to enter the lower shell 312. In the lower shell 312, the mixed liquid will be layered, and the lighter oil layer will go upward, while the heavier impurities or seawater will go downward.

[0024] The upper shell 311 is provided with a recovery chamber 50, the lower end of the recovery chamber 50 is connected to a guide portion 52 through a connecting portion 51, and the top of the recovery chamber 50 is connected to the connecting pipe 23. In the lower shell 312, due to the generation of vortex, the oil and liquid are separated, the lighter oil enters the recovery chamber 50 through the guide portion 52, and the heavier seawater is discharged from the bottom discharge port of the lower shell 312.

[0025] Working principle: First, the oil spill layer on the sea level and a small amount of seawater are screwed into the separation cylinder 31 through the screw-in part 32, and enter the interior of the upper shell 311 through the inlet 323, and then pass through the guide platform 314. The mixed liquid passing through the guide platform 314 generates a vortex, and the mixed liquid under the vortex will be separated. The lighter oil spill passes through the guide part 52 into the recovery chamber 50 and is discharged through the connecting pipe 23, while the heavier seawater and other heavier materials are discharged from the lower discharge port of the lower shell 312. The purpose of separating the oil spill at sea is achieved.
