[0068] As shown in Figure 1 , the present application provides a pneumatic offshore floating oil cyclone separation and recovery device, which comprises a cyclone separation part, an oil storage part 5 and a buoyancy part. The offshore floating oil is separated by the cyclone separation part, the oil is stored by the oil storage part 5, the buoyancy and power are provided by the buoyancy part, the device is pushed to rotate on the sea surface to collect oil, and the operator is facilitated to recover the device.

[0069] As shown in Figures 1-2 and Figures 4-7As shown in the figure, the cyclone separation part comprises a cyclone second shell 3 and two cyclone first shells 1 arranged respectively at the left and right ends of the cyclone second shell 3. The side wall of each cyclone first shell 1 is provided with a liquid inlet 11 and a cyclone communication hole 13, and a cone 2 is arranged inside. The cone 2 is horizontally arranged (i.e. the axial direction of the cone 2 is parallel to the left-right direction), and the tip of the cone 2 extends to the outside of the cyclone communication hole 13 and enters the inside of the cyclone second shell 3. The side wall of the cyclone second shell 3 is provided with a water outlet, the bottom is provided with a through hole 33, and two cyclones 81 are arranged oppositely inside. The cyclone 81 is conical and hollow, comprising a large-diameter end, an underflow port 812 and a plurality of water outlet holes 811 arranged in the middle of the cyclone 81. The inner diameter of the large-diameter end is larger than that of the underflow port 812. The large-diameter end is fixed to the outer periphery of the cyclone communication hole 13, and the tip of the cone 2 enters the inside of the cyclone 81 from the large-diameter end. The underflow port 812 is connected with the three-way pipe 4. The left and right ends of the three-way pipe 4 are respectively connected with a cyclone 81.

[0070] In a specific embodiment of the present application, as shown in the figure, Figure 5 The inside of the cyclone first shell 1 is provided with a cyclone cavity 12, and the cone 2 is arranged in the cyclone cavity 12. The side wall of the cyclone cavity 12 is further provided with a cone fixing hole 14, and the cone 2 is threadedly connected with the cone fixing hole 14. A plurality of connecting ears 15 are further arranged on the outer side wall of the cyclone first shell 1, and the cyclone first shell 1 can be connected and fixed with the buoyancy part, the oil storage part 5 and the cyclone second shell 3 through the connecting ears 15. The large-diameter end of the cyclone 81 is welded to the outer periphery of the cyclone communication hole 13 to realize axial positioning. The underflow port 812 of the cyclone 81 is provided with external threads, and the cyclone 81 is detachably connected with the three-way pipe 4 through the external threads. As shown in the figure, Figure 6 The cyclone second shell 3 is a long rectangular hollow structure with open ends, and is fixedly connected with the cyclone first shell 1 through the connecting ears.

[0071] As shown in the figure, Figures 1-3 and Figure 8 The oil storage part 5 is arranged below the cyclone separation part, and is provided with an oil inlet pipe 52 and an oil outlet valve 51 respectively. The oil inlet pipe 52 is inserted into the through hole 33 and connected with the lower end of the three-way pipe 4. The oil separated by the cyclone separation part can enter the oil storage part 5 through the three-way pipe 4, and finally be discharged through the oil outlet valve 51 and be recycled. Specifically, the oil storage part 5 is a closed rectangular hollow structure, and is further provided with a one-way air outlet 53. The one-way air outlet 53 only allows the gas inside the oil storage part 5 to be discharged outward, and the gas and liquid outside cannot enter the oil storage part 5 through the one-way air outlet 53. The function of the one-way air outlet 53 is to balance the air pressure inside the oil storage part 5, so that the oil can smoothly enter the oil storage part 5. A one-way valve can be used as the one-way air outlet 53.

[0072] As shown in the figure, Figures 1-3 , Figure 9 and Figure 11As shown, the buoyancy part includes an upper float 61 arranged above the cyclone separation part and a high-pressure air bag 62 arranged below the oil storage part 5. The upper float 61 serves to provide buoyancy for the device, ensuring that the entire device can maintain a floating posture on the sea surface even when the oil storage part 5 is fully loaded, facilitating recovery by the operator. The front side and the rear side of the high-pressure air bag 62 are each provided with an exhaust port, i.e., a first exhaust port 621 and a second exhaust port 622, which are respectively located at the left and right ends of the high-pressure air bag 62. The two exhaust ports are the same in structure except for the different positions. The operator can inject high-pressure gas into the high-pressure air bag 62 through the first exhaust port 621 and the second exhaust port 622, and then place the device on the sea surface. When the high-pressure gas is simultaneously discharged outward through the first exhaust port 621 and the second exhaust port 622, the entire device is pushed to rotate on the sea surface. Specifically, the upper float 61 can be a solid foam floating member, which is connected to the lower cyclone first shell 1 through connecting ears. The high-pressure air bag 62 is a cylindrical hollow component made of rubber or composite material, which has excellent elasticity and wear resistance. A lower connecting ear 63 is arranged on the high-pressure air bag 62, and the high-pressure air bag 62 and the oil storage part 5 are connected together through the lower connecting ear 63.

[0073] As shown in Figure 1 , Figure 3 , Figures 9-11 , the number of high-pressure air bag valves 7 is two, and each of the first exhaust port 621 and the second exhaust port 622 is provided with one high-pressure air bag valve 7. The high-pressure air bag valve 7 includes a connecting rod 72, a float 71 arranged at the upper end of the connecting rod 72, and a gate block 73 arranged at the lower end of the connecting rod 72, and the connecting rod 72 is slidably connected with the exhaust port. The gate block 73 moves up and down with the float 71 under different buoyancy, blocks the exhaust port to different degrees, changes the exposed area of the exhaust port, and then adjusts the exhaust volume of the high-pressure air bag 62, prolonging the working time of the device. Specifically, the float 71 is spherical. As shown in Figure 11 , the second exhaust port 622 includes a chute 6221, a plurality of exhaust holes arranged on the side wall of the chute 6221, and a connecting rod sliding hole 6222 arranged on the top of the chute 6221, the connecting rod 72 passes through the connecting rod sliding hole 6222, and the gate block 73 is slidably arranged in the chute 6221. The gate block 73 slides up and down in the chute 6221, which can change the number of exhaust holes in communication with the outside, achieving the adjustment of the exhaust volume. To prevent the connecting rod 72 from shaking left and right, further, as shown in Figure 1 and Figure 5 , a connecting rod sliding hole 16 is also arranged on the side wall of the cyclone first shell 1, the connecting rod 72 passes through the connecting rod sliding hole 16, and the connecting rod sliding hole 16 limits the connecting rod 72 in the front-rear and left-right directions, allowing only the upward and downward displacement of the connecting rod 72.

[0074] The working principle of the present application is as follows:

[0075] The operator injects high-pressure gas into the high-pressure air bag 62 through the exhaust port of the high-pressure air bag 62 in advance, and then makes the device freely float on the sea surface. The first exhaust port 621 and the second exhaust port 622 simultaneously exhaust high-pressure gas outward, pushing the entire device to rotate on the sea surface in the up-down direction. The oil-water mixture on the sea enters the cyclone cavity 12 of the first outer shell 1 of the cyclone through the liquid inlet 11, and rotates with the entire device. The cone 2 plays a lifting role on the oil-water mixture, pushing the oil-water mixture from the direction of the liquid inlet 11 to the direction of the cyclone 81. Because the densities of oil and water are different, the centrifugal forces they receive in the cyclone 81 are also different. The water phase with higher density is close to the inner wall of the cyclone 81, and then flows out from the drain hole 811 and the drain port opened on the side wall of the second outer shell 3 of the cyclone into the sea; the oil phase with lower density tends to move along the axis direction of the cyclone 81, and finally enters the oil storage part 5 through the three-way pipe 4.

[0076] Further, a drain port, i.e., the first drain port 31 and the second drain port 32, is opened on the front and rear side walls of the second outer shell 3 of the cyclone, respectively. The first drain port 31 and the second drain port 32 are located at the left and right ends of the second outer shell 3 of the cyclone, respectively. When a large amount of water is accumulated in the second outer shell 3 of the cyclone, the internal water pressure of the second outer shell 3 of the cyclone will drive the water to be simultaneously sprayed out from the first drain port 31 and the second drain port 32, supplementing the driving force for the rotational movement of the device.

[0077] The above is only the preferred embodiment of the present application. It should be noted that for ordinary skilled persons in the technical field, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
