[0019] Compared with the prior art, the present invention provides a multifunctional oil spill treatment device on water and a method for recovering oil spill in water areas, which have the following beneficial effects:

[0020] 1. The multifunctional aquatic oil spill treatment device and the method for recovering oil spilled in waters are characterized in that the first motor drives the threaded block to move downward after the screw rod is rotated, and the telescopic tube of the auxiliary component drives the filter screen and the fixed cylinder to move downward through the movable seat, and the moving distance can be adjusted according to the oil spill thickness measured by the external detection equipment, so as to improve the recovery efficiency. The second motor drives the telescopic tube and the propeller outside the telescopic tube to rotate, and at this time, a vortex eddy current is formed in this area, causing the floating oil in this area to settle downward with the vortex, so that the oil can be quickly recovered effectively, and the recovery efficiency of the oil spill is effectively improved;

[0021] The multifunctional on-water oil spill treatment device and the method for recovering oil spill in water areas drive the crushing shaft and the crushing blade on its outer side to rotate and cut various garbage through the telescopic tube through the fixed sleeve, and the scraper rotates continuously with the rotation of the telescopic tube to scrape the crushed and cut garbage from the feed port to the collection box for collection, so as to facilitate the effective cleaning and recovery of marine garbage, and avoid seaweed and other garbage clogging the filter screen to affect the normal oil absorption work. After the oil is recovered, the sealing cover is opened, and the garbage is manually entered to be taken out for collection and treatment;

[0022] The multifunctional aquatic oil spill treatment device and the method for recovering oil spill in water areas drive the stirring shaft to rotate through the output shaft of the third motor. After the stirring shaft generates centrifugal force due to the rotation, the ring and the stirring rod connected through the connecting ring in the outer groove of the stirring shaft are driven to swing, and the stirring rod gradually forms a vertical angle with the stirring shaft. After the oil-water mixture is continuously rotated and stirred at a high speed by a plurality of stirring rods, the oil-water mixture is centrifugally separated, so that the oil body is concentrated above the water, which is convenient for rapid and effective oil-water separation and improves the separation efficiency. The air pump transmits air to the hard pipe and the rectangular air pipe through the hose, and the air is discharged through the multiple air holes on the outer sides of the hard pipe and the rectangular air pipe to generate bubbles, which is convenient for using the bubbles to float upward with the oil with lower density. As the bubbles continue to move upward, the smaller oil droplets in the water body that have been initially centrifugally separated are adsorbed, and the smaller oil droplets are moved upward to the top of the oil-water separation layer, so that the oil and water are separated again, which is beneficial to reducing the range of oil droplets in the water body, further reducing the oil content in the water, and effectively improving the effect of oil separation.

[0042] Another method for recovering oil spilled in waters proposed by the present invention comprises the following steps:

[0043] Step 1: driving the ship 1 to the working area where oil spill treatment is required;

[0044] Step 2: Turn on the first motor 211 of the oil suction assembly 21 in the recovery mechanism 2 through an external controller. The first motor 211 drives the threaded block 213 to move downward after being rotated by the screw rod 212. The threaded block 213 drives the auxiliary assembly 22 to move downward through the support plate 215 and the bearing seat 216.

[0045] Step 3: Turn on the second motor 221 of the auxiliary component 22 in the recovery mechanism 2 through an external controller. The second motor 221 drives the telescopic tube 222 and the propeller 223 on its outer side to rotate. At this time, a vortex eddy current is formed in this area, causing the floating oil in this area to settle downward with the vortex current. By turning on the first oil suction pump 2111, the first oil suction pump 2111 sucks oil through the pipeline, and then the oil-water mixture is transported to the separation mechanism 3 through the first oil delivery pipe 2112, which effectively improves the efficiency of oil spill recovery.

[0046] Step 4: When the first oil delivery pipe 2112 enters the separation box 31, the U-shaped baffle 32 is used to buffer and block the oil-water mixture, so that it can flow slowly to the lower end of the inner cavity of the separation box 31. The switch of the third motor 36 is turned on by the external controller, and then the third motor 36 drives the stirring shaft 371 to rotate through the output shaft. After the stirring shaft 371 generates centrifugal force due to the rotation, it drives the ring 374 and the stirring rod 375 in the outer groove 372 connected by the connecting ring 373 to swing, and the stirring rod 375 gradually forms a vertical angle with the stirring shaft 371. After the oil-water mixture is continuously rotated and stirred at a high speed by a plurality of stirring rods 375, the oil-water mixture is centrifugally separated, so that the oil body is concentrated above the water. After the third motor 36 has worked for a period of time, the third motor 36 is turned off and the air pump is turned on at the same time. 38 and the switch of the electric push rod 34, the air pump 38 transports air to the hard tube 311 and the rectangular air tube 310 through the hose 39, and the air is discharged through the multiple air holes on the outside of the hard tube 311 and the rectangular air tube 310 to generate bubbles. At this time, the electric push rod 34 drives the mounting cover 35, the third motor 36, and the stirring assembly 37 to move upward by contracting the output rod. At this time, the stirring assembly 37 drives the hard tube 311 and the rectangular air tube 310 to move slowly upward through the connecting seat 312, so that the air holes on the outside of the hard tube 311 and the rectangular air tube 310 continuously discharge bubbles upward, and it is convenient to use the bubbles to carry the oil with lower density to float upward. As the bubbles continue to move upward, they absorb smaller oil droplets in the water body that has been initially centrifugally separated, and move them upward to above the oil-water separation layer, so that the oil and water are separated again, which effectively improves the effect of oil separation;

[0047] Step 5: Turn on the switch of the second oil suction pump 41 through the external controller, the second oil suction pump 41 sucks out the separated oil through the oil suction pipe 42, and then delivers it to one of the oil storage tanks 45 through the second oil delivery pipe 43, and the oil storage tanks 45 are connected to each other through the connecting pipe 46 to facilitate the rapid delivery and storage of oil;

[0048] Step 6: After the oil is recovered, the sealing cover 232 is opened, and the garbage is manually taken out from the collection box 231 for collection and treatment, so as to facilitate the recycling of the garbage.

[0049] Working principle: The present invention controls and connects the first motor 211, the first oil suction pump 2111, the second motor 221, the electric push rod 34, the third motor 36, the air pump 38, and the second oil suction pump 41 through an external controller. In the studio, the hull 1 is driven to the working area where oil spill treatment is required, and the first motor 211 is turned on through the external controller. The first motor 211 drives the threaded block 213 to move downward after the screw rod 212 rotates, and at the same time, the bearing seat 216 is movably connected through the telescopic tube 222, and the bearing seat 216 is fixedly installed with the support plate 215, so that the support plate 215 moves downward and drives the outer tube of the telescopic tube 222 to move downward, that is, drives the spiral block 213 on the outer side of the telescopic tube 222 to move downward. As the paddle 223 moves downward, the telescopic tube 222 drives the filter screen 218 and the fixed cylinder 217 to move downward through the movable seat 219. The moving distance can be adjusted according to the thickness of the oil spill measured by the external detection equipment, so as to improve the recovery efficiency. By turning on the second motor 221, the second motor 221 drives the telescopic tube 222 and the propeller 223 outside the telescopic tube 222 to rotate. At this time, a vortex eddy current is formed in this area, causing the floating oil in this area to settle downward with the vortex, so that the oil can be quickly and effectively recovered. Then, the first oil suction pump 2111 is used to suck oil through the pipeline, and then the oil-water mixture is transported to the separation mechanism 3 through the first oil delivery pipe 2112, so as to effectively improve the recovery efficiency of the oil spill.

[0050] At the same time, the telescopic tube 222 drives the crushing shaft 225 and the crushing blade 226 on its outer side to rotate and cut various garbage through the fixed sleeve, and the scraper 224 rotates continuously with the rotation of the telescopic tube 222, and the crushed and cut garbage is scraped from the feed port 233 to the collection box 231 for collection, which is convenient for effective cleaning and recycling of marine garbage, and avoids seaweed and other garbage clogging the filter screen 218 and affecting the normal oil suction work. After the oil is recovered, the sealing cover 232 is opened, and the garbage is manually entered to be taken out for collection and processing, and the oil-water mixture is buffered and blocked by the U-shaped baffle 32, which is convenient for the mixture to pass through. The oil slowly flows through the first oil delivery pipe 2112 to the lower end of the inner cavity of the separation box 31, and the third motor 36 drives the stirring shaft 371 to rotate through the output shaft. The stirring shaft 371 generates centrifugal force due to rotation, which drives the sleeve ring 374 and the stirring rod 375 in the outer groove 372 thereof, which are sleeved by the connecting ring 373, to swing, and the stirring rod 375 gradually forms a vertical angle with the stirring shaft 371. After the oil-water mixture is continuously rotated and stirred at a high speed by a plurality of stirring rods 375, the oil-water mixture is centrifugally separated, so that the oil body is concentrated above the water, which is convenient for rapid and effective oil-water separation, thereby improving the separation efficiency;

[0051] After the third motor 36 has worked for a period of time, the third motor 36 is turned off and the switches of the air pump 38 and the electric push rod 34 are turned on at the same time. The air pump 38 delivers air to the hard tube 311 and the rectangular air tube 310 through the hose 39, and the air is discharged through the multiple air holes on the outside of the hard tube 311 and the rectangular air tube 310 to generate bubbles. At this time, the electric push rod 34 drives the mounting cover 35, the third motor 36, and the stirring assembly 37 to move upward by contracting the output rod. At this time, the stirring assembly 37 drives the hard tube 311 and the rectangular air tube 310 to move slowly upward through the connecting seat 312, so that the air holes on the outside of the hard tube 311 and the rectangular air tube 310 can continuously move upward. The bubbles are discharged, so that the bubbles can be used to float upward with the oil with lower density. As the bubbles move upward, they absorb the smaller oil droplets in the water body that has been initially centrifugally separated, and move them upward to above the oil-water separation layer, so that the oil and water are separated again, which is beneficial to reduce the scope of the oil droplets in the water body, further reduce the oil content in the water, and effectively improve the effect of oil separation. The second oil suction pump 41 is used to suck out the separated oil through the oil suction pipe 42, and then transport it to one of the oil storage tanks 45 through the second oil pipeline 43. The oil storage tanks 45 are connected to each other by a connecting pipe 46 for oil transportation, which is convenient for rapid transportation and storage of oil.
