an insulation board 8 is horizontally and fixedly arranged between the adjacent side walls of the two floating cylinders 101, the insulation board 8 is matched with the oil absorption roller 4, and a pre-cooling mechanism matched with the oil absorption roller 4 is arranged on the mounting plate 102;

the pre-cooling mechanism comprises an insulation box 9 fixedly mounted on the side wall of the cooling box 5, the insulation box 9 is located between the cooling box 5 and the heating box 6, the conveying belt 3 and the oil absorption roller 4 penetrate through the insulation box 9, a heat conduction plate 10 is fixedly mounted in the insulation box 9, a first cavity 11 is formed in the heat conduction plate 10, and a cooling mechanism matched with the first cavity 11 is arranged on the insulation plate 8.

The cooling mechanism comprises a guide plate 12 which is horizontally and fixedly installed on the side wall of the heat insulation plate 8, the guide plate 12 is made of heat insulation materials, a groove 13 is formed in the guide plate 12, a heat conducting fin 14 is fixedly installed at the top end of the groove 13, a guide pipe 15 which extends into the first cavity 11 is fixedly installed on the side wall of the groove 13, and heat conducting oil is filled in the space between the first cavity 11, the heat conducting fin 14 and the groove 13 and the guide pipe 15.

Firstly, a motor is arranged on a ship body 1, a power output shaft of the motor is fixedly connected with a rotating shaft of a rotating roller 2, and then a cooling box 5 and a heating box 6 are started; in the working process, the ship body 1 sails on the sea surface, and in the sailing process of the ship body 1, the heat insulation plate 8 is positioned below the water surface; in the process that the motor drives the rotating roller 2 to rotate, the rotating roller 2 drives the conveying belt 3 to move, in the moving process of the conveying belt 3, the conveying belt 3 drives the oil suction roller 4 to move together, when the conveying belt 3 drives the oil suction roller 4 to move into the cooling box 5, under the action of the cooling box 5, the temperature of the oil suction roller 4 is reduced, then the oil suction roller 4 continues to move along with the conveying belt 3, when the oil suction roller 4 is contacted with seawater on the top wall of the heat insulation plate 8, the oil suction roller 4 absorbs heat of oil stains floating on the water surface, so that the oil stains can be cooled, the oil stains reach a freezing point, the oil stains are solidified and are attached to the surface of the oil suction roller 4, after the oil stains are attached to the surface of the oil suction roller 4, the conveying belt 3 continues to drive the oil suction roller 4 to move, when the oil suction roller 4 with solid oil stains attached to the surface moves into the heating box 6, the heat dissipated from the heating box 6 heats the oil suction roller 4, so that the solid oil stains on the surface of the oil suction roller 4 are heated and melted into liquid, and then the liquid oil stains drop downwards into the collection box 7 under the action of gravity, thereby realizing the function of cleaning the oil stains on the sea surface.

When the ship body 1 sails on the sea surface, the heat insulation plate 8 is positioned below the water surface, so that seawater containing oil stains in the sea is positioned above the top wall of the heat insulation plate 8, namely the seawater containing oil to be cleaned is separated from the seawater in the sea, and the heat insulation plate 8 has a heat insulation effect, so that the heat transmitted to the oil suction roller 4 by the seawater is reduced when the oil suction roller 4 is contacted with the oil stains, a large temperature difference between the oil stains and the oil suction roller 4 is ensured, the solidification speed of the oil stains is accelerated, and the effect of ensuring that the oil stains can be solidified is achieved; meanwhile, the workload of the cooling box 5 is reduced, the oil suction roller 4 does not need to be reduced to a very low temperature, and the effect of saving resources is achieved.

When the oil suction roller 4 cools and solidifies the oil stain on the top wall of the heat insulation board 8, the temperature of the seawater above the heat insulation board 8 is also reduced, because the ship body 1 sails on the sea surface, relative displacement exists between the seawater above the heat insulation board 8 and the heat insulation board 8, the heat insulation board 8 is used as a reference object, the seawater above the heat insulation board 8 moves along the top wall of the heat insulation board 8, the seawater above the heat insulation board 8 passes through the surface of the heat insulation board 8, when the seawater moves above the guide plate 12, the guide plate 12 also has the heat insulation effect, therefore, the seawater above the guide plate 12 can not exchange heat with the seawater below the guide plate 12, the seawater above the guide plate 12 is in a low-temperature state, at the moment, under the action of the heat conducting plate 14, the seawater absorbs the heat of the heat conducting oil, so that the heat conducting oil can be cooled, at the moment, the heat conducting oil in the space between the first cavity 11, the guide pipe 15, the heat conducting plate 14 and the groove 13 is in a low-temperature state, and the heat-conducting plate 10 is also in a low temperature state by the heat exchange.

When the conveying belt 3 drives the oil absorption roller 4 which is heated to remove oil to pass through the heat insulation box 9, the oil absorption roller 4 is in contact with the heat conduction plate 10, and at the moment, the heat conduction plate 10 with lower temperature absorbs the heat of the oil absorption roller 4 under the action of heat exchange, so that the temperature of the oil absorption roller 4 is reduced, the absorption capacity of the cooling box 5 to the heat of the oil absorption roller 4 is reduced, namely, the working strength of the cooling box 5 is reduced, and the resource is saved; because the initial temperature of oil suction roller 4 when getting into cooling box 5 is lower, consequently at cooling box 5 with oil suction roller 4 reduce the in-process to the assigned temperature, oil suction roller 4 can reach the assigned temperature fast, has shortened the cool-down time to can improve the moving speed that conveyer belt 3 drove oil suction roller 4, played the effect that improves work efficiency.

Specifically, as shown in fig. 4, an installation sleeve 16 is fixedly installed on the heat preservation box 9, a first one-way valve 17 and a second one-way valve 18 are fixedly installed on the side wall of the installation sleeve 16, and a driving mechanism for driving liquid in the installation sleeve 16 to flow is arranged on the heat preservation box 9, wherein the conduit 15 is communicated with the first cavity 11 through the first one-way valve 17, the second one-way valve 18 and the installation sleeve 16.

The driving mechanism comprises a push rod 19 which is vertically and movably inserted on the top wall of the heat preservation box 9, and the side wall of the push rod 19 is an inclined surface which inclines upwards.

In the initial state, the push rod 19 is hung on the top wall of the heat preservation box 9 under the action of gravity; in the working process, the rotating roller 2 drives the conveying belt 3 and the oil suction roller 4 to move, at the moment, the oil suction roller 4 intermittently contacts with the push rod 19, when the oil suction roller 4 contacts with the push rod 19, the oil suction roller 4 applies horizontal thrust to the side wall of the push rod 19, at the moment, under the action of the inclined plane, the thrust is decomposed in the direction along the inclined plane and in the vertical upward direction, and under the action of vertical upward component force, the push rod 19 moves upwards, so that in the working process of the conveying belt 3, the push rod 19 is in an intermittent upwards moving state.

(first one-way valve 17: the heat conducting oil in the conduit 15 can only pass through the first one-way valve 17 and enter the mounting sleeve 16; second one-way valve 18: the heat conducting oil in the mounting sleeve 16 can only pass through the second one-way valve 18 and flow outwards.) when the push rod 19 moves upwards, the top end of the push rod 19 extends into the mounting sleeve 16, the space in the mounting sleeve 16 is occupied by the push rod 19 at the moment, so that the pressure in the mounting sleeve 16 is increased, therefore, under the action of the first one-way valve 17 and the second one-way valve 18, the heat conducting oil in the mounting sleeve 16 flows out of the second one-way valve 18 and flows into the first cavity 11, when the push rod 19 moves downwards, the push rod 19 extends out of the mounting sleeve 16, the volume in the mounting sleeve 16 is increased at the moment, the pressure in the mounting sleeve 16 is reduced at the moment, the first one-way valve 17 is opened at the moment, so that the temperature in the conduit 15 is lower and enters the mounting sleeve 16, and when the push rod 19 again extends into the mounting sleeve 16, the low-temperature heat conduction oil in the mounting sleeve 16 is extruded into the first cavity 11 again, so that in the intermittent upward moving process of the push rod 19, the heat conduction oil with lower temperature in the space formed between the heat conduction sheet 14 and the groove 13 can be transferred into the first cavity 11, so that the heat conduction plate 10 is kept in a low-temperature state, and the effect of improving the cooling effect of the heat conduction plate 10 on the oil suction roller 4 is achieved.

Specifically, as shown in fig. 4, an elastic membrane 20 is fixedly mounted on the inner bottom wall of the mounting sleeve 16, and the elastic membrane 20 covers the top end of the push rod 19.

Along with the increase of the service time, the gap between the push rod 19 and the mounting sleeve 16 is gradually increased, and at the moment, under the action of the elastic membrane 20, the heat conduction oil in the mounting sleeve 16 can be prevented from entering the gap between the push rod 19 and the mounting sleeve 16, so that the effect of preventing the heat conduction oil from leaking is achieved; and in the process that the push rod 19 moves upwards, the elastic membrane 20 is stretched, and at the moment, the elastic membrane 20 is in a 'table shape', when the elastic membrane 20 is jacked up by the push rod 19, the section of the table-shaped body formed between the elastic membrane 20 and the bottom wall of the mounting sleeve 16 is trapezoidal, relative to the situation that the push rod 19 enters the mounting sleeve 16, the space in the mounting sleeve 16 is further occupied, namely, the pressure in the mounting sleeve 16 is further increased, so that the discharge amount of heat conduction oil in the mounting sleeve 16 is increased, the flow speed of the heat conduction oil in the first cavity 11 is increased, and the effect of ensuring that the heat conduction plate 10 can keep a low-temperature state is achieved.

Specifically, as shown in fig. 3, a second cavity 21 is formed in the heat insulation board 8, an air tap 22 extending into the second cavity 21 is uniformly and vertically fixedly inserted into the top wall of the heat insulation board 8, and an air supply mechanism matched with the second cavity 21 is arranged on the mounting plate 102.

The air supply mechanism comprises a sleeve 23 fixedly embedded on the top wall of the mounting plate 102, a pressure plate 24 made of magnetic materials is movably arranged in the sleeve 23, an air inlet valve 25 and an air outlet valve 26 are embedded on the side wall of the sleeve 23, an air outlet pipe 27 extending into the second cavity 21 is fixedly installed on the air outlet valve 26, and a magnet 28 mutually repelling with the pressure plate 24 is fixedly embedded at the top end of the push rod 19.

In the initial state, the bottom wall of the pressure plate 24 is attached to the top walls of the air inlet valve 25 and the exhaust valve 26, the push rod 19 intermittently moves upwards in the working process, when the push rod 19 moves upwards, the push rod 19 is close to the pressure plate 24, the pressure plate 24 moves upwards along the sleeve 23 under the action of repulsive force, the air pressure in the space below the pressure plate 24 in the sleeve 23 is reduced in the process that the pressure plate 24 moves upwards, and the space sucks air from the outside through the air inlet valve 25 under the action of the air inlet valve 25 and the exhaust valve 26; when the push rod 19 moves downwards, the press plate 24 moves downwards under the action of gravity, at the same time, the press plate 24 applies pressure to the gas in the sleeve 23, at the same time, under the action of the pressure, the exhaust valve 26 and the intake valve 25, the gas in the space below the press plate 24 in the sleeve 23 is exhausted through the exhaust pipe 27, the exhausted gas flows into the cavity along the exhaust pipe 27, the gas in the cavity flows upwards through the air nozzle 22, when the gas flows out of the air nozzle 22, the gas flow floats upwards in the form of bubbles, when the bubbles float to the surface of the liquid level, the bubbles are burst, the impact force generated by the burst bubbles pushes the oil stains floating on the water surface, so that the oil stains are scattered all around, part of the oil stains are attached to the top wall of the oil suction roller 4, so that the oil stains can be rapidly contacted with the oil suction roller 4, and the oil suction roller 4 can absorb a large amount of heat of the oil stains instead of the air, the function of improving the temperature utilization rate of the oil suction roller 4 is achieved.

Specifically, as shown in fig. 3, a funnel 29 is horizontally and fixedly mounted between the adjacent side walls of the two buoys 101, the diameter of the funnel 29 gradually increases from top to bottom, and an air inlet pipe 30 communicated with the air inlet valve 25 is fixedly mounted at the top end of the funnel 29.

When the bubbles flow out from the air nozzle 22, the bubbles are in contact with the seawater with lower temperature, and the temperature of the bubbles is also lower under the action of heat exchange, so that when the bubbles burst, the airflow with lower temperature in the bubbles enters the funnel 29 and is absorbed into the sleeve 23 through the air inlet pipe 30, so that the gas can be recycled, the temperature difference between the airflow discharged from the air nozzle 22 and the low-temperature seawater is reduced, and the effect of preventing the temperature of the seawater from rising and transferring heat to the oil suction roller 4 is achieved.

Specifically, as shown in fig. 6, the heat conducting plate 10 is uniformly and fixedly mounted with an elastic strip 31 extending into the first cavity 11, the elastic strip 31 is matched with the oil suction roller 4, and the elastic strip 31 is provided with a third cavity 32 communicated with the first cavity 11.

In the initial state, the elastic strip 31 is in a vertical state, the elastic sleeve is in contact with the side wall of the oil absorption roller 4 at the moment, and the elastic strip 31 slides over the surface of the oil absorption roller 4 in the process that the conveyor belt 3 drives the oil absorption roller 4 to pass through the heat insulation box 9; because first cavity 11 and third cavity 32 intercommunication, consequently when heat conduction oil flows to first cavity 11 in, be full of the heat conduction oil in the third cavity 32 equally to can cool down oil suction roll 4 when elasticity strip 31 slides oil suction roll 4 surface, for only relying on heat-conducting plate 10 and oil suction roll 4 to contact, play the effect that improves the cooling effect.

Specifically, as shown in fig. 4, a communication pipe 33 extending to the inner top wall of the thermal insulation box 9 is fixedly inserted into the bottom wall of the mounting sleeve 16, a rotary spray head 34 is fixedly mounted on the bottom wall of the communication pipe 33, and a third check valve 35 having an output end extending to the inner bottom wall of the mounting sleeve 16 is fixedly mounted on the inner top wall of the thermal insulation box 9.

When the push rod 19 moves upwards, under the action of the third one-way valve 35, the space between the inner bottom wall of the mounting sleeve 16 and the elastic membrane 20 absorbs gas from the heat-insulating sleeve, because the gas with higher temperature in the insulating sleeve is positioned on the inner top wall of the insulating sleeve, the gas with higher temperature is absorbed into the space between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 through the third one-way valve 35 to cool the gas with higher temperature, when the push rod 19 moves down and the elastic membrane 20 is restored, the gas having a lower temperature between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 flows into the rotary sprayer 34 through the communication pipe 33, at this time, the rotary nozzle 34 is rotated rapidly, so that the gas sprayed therein at a relatively low temperature is diffused throughout the mounting sleeve 16, thereby can be for the cooling of whole installation cover 16, consequently the roller 4 that absorbs oil will be in the low temperature environment to the effect of the cooling effect of the roller 4 that absorbs oil has been played and has been improved. And when the air current passes through the third check valve 35, the space formed between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 can be constantly pressurized, which serves to ensure that the push rod 19 can smoothly move upward.

The working principle is as follows: firstly, a motor is arranged on a ship body 1, a power output shaft of the motor is fixedly connected with a rotating shaft of a rotating roller 2, and then a cooling box 5 and a heating box 6 are started; in the working process, the ship body 1 sails on the sea surface, and in the sailing process of the ship body 1, the heat insulation plate 8 is positioned below the water surface; in the process that a motor drives a rotating roller 2 to rotate, the rotating roller 2 drives a conveyor belt 3 to move, in the process that the conveyor belt 3 moves, the conveyor belt 3 drives an oil suction roller 4 to move together, when the conveyor belt 3 drives the oil suction roller 4 to move into a cooling box 5, under the action of the cooling box 5, the temperature of the oil suction roller 4 is reduced, then the oil suction roller 4 continues to move along with the conveyor belt 3, when the oil suction roller 4 is in contact with seawater on the top wall of a heat insulation board 8, the oil suction roller 4 absorbs heat of oil stains floating on the water surface at the moment, so that the oil stains can be cooled, the oil stains reach a solidifying point, the oil stains are solidified and attached to the surface of the oil suction roller 4, after the oil stains are attached to the surface of the oil suction roller 4, the conveyor belt 3 continues to drive the oil suction roller 4 to move, when the oil suction roller 4 with the solid oil stains attached to the surface moves into a heating box 6, the heat dissipated from the heating box 6 heats the oil suction roller 4, thereby make the solid greasy dirt on oil suction roller 4 surface be heated the melting to liquid, then in liquid greasy dirt drips to collecting box 7 under the effect of gravity to the effect of clearing up sea greasy dirt has been realized.

First check valve 17: the heat conducting oil in the conduit 15 can only pass through the first one-way valve 17 to enter the mounting sleeve 16; second check valve 18: the heat conducting oil in the mounting sleeve 16 can only flow outwards through the second one-way valve 18, when the push rod 19 moves upwards, the top end of the push rod 19 extends into the mounting sleeve 16, at the same time, the space in the mounting sleeve 16 is occupied by the push rod 19, so that the pressure in the mounting sleeve 16 is increased, therefore, under the action of the first one-way valve 17 and the second one-way valve 18, the heat conducting oil in the mounting sleeve 16 flows out from the second one-way valve 18 and flows into the first cavity 11, when the push rod 19 moves downwards, the push rod 19 extends out from the mounting sleeve 16, at the same time, the volume in the mounting sleeve 16 is increased, so that the pressure in the mounting sleeve 16 is reduced, at the same time, the first one-way valve 17 is opened, so that the heat conducting oil with lower temperature in the conduit 15 enters the mounting sleeve 16, when the push rod 19 extends into the mounting sleeve 16 again, the low-temperature heat conducting oil in the mounting sleeve 16 is squeezed again into the first cavity 11, so that during the intermittent upwards movement of the push rod 19, the heat conducting oil with lower temperature in the space formed between the heat conducting fins 14 and the grooves 13 can be transferred into the first cavity 11, so that the heat conducting plate 10 keeps a low-temperature state, and the effect of improving the cooling effect of the heat conducting plate 10 on the oil suction roller 4 is achieved.

Along with the increase of the service time, the gap between the push rod 19 and the mounting sleeve 16 is gradually increased, and at the moment, under the action of the elastic membrane 20, the heat conduction oil in the mounting sleeve 16 can be prevented from entering the gap between the push rod 19 and the mounting sleeve 16, so that the effect of preventing the heat conduction oil from leaking is achieved; and in the process that the push rod 19 moves upwards, the elastic membrane 20 is stretched, and at the moment, when the elastic membrane 20 is in a 'table shape', and when the elastic membrane 20 is jacked up by the push rod 19, the section of the table-shaped body formed between the elastic membrane 20 and the bottom wall of the mounting sleeve 16 is trapezoidal, relative to the situation that the push rod 19 enters the mounting sleeve 16, the section occupies the space in the mounting sleeve 16, namely, the pressure in the mounting sleeve 16 is further increased, so that the discharge amount of heat conduction oil in the mounting sleeve 16 is increased, the flow speed of the heat conduction oil in the first cavity 11 is increased, and the effect of ensuring that the heat conduction plate 10 can keep a low-temperature state is achieved.

When the bubbles flow out from the air nozzle 22, the bubbles are in contact with the seawater with lower temperature, and the temperature of the bubbles is also lower under the action of heat exchange, so that when the bubbles burst, the airflow with lower temperature in the bubbles enters the funnel 29 and is absorbed into the sleeve 23 through the air inlet pipe 30, so that the gas can be recycled, the temperature difference between the airflow discharged from the air nozzle 22 and the low-temperature seawater is reduced, and the function of preventing the temperature of the seawater from rising and transferring heat to the oil suction roller 4 is achieved.

In the initial state, the elastic strip 31 is in a vertical state, the elastic sleeve is in contact with the side wall of the oil absorption roller 4 at the moment, and the elastic strip 31 slides over the surface of the oil absorption roller 4 in the process that the conveyor belt 3 drives the oil absorption roller 4 to pass through the heat insulation box 9; because the first cavity 11 is communicated with the third cavity 32, when the heat conduction oil flows into the first cavity 11, the third cavity 32 is filled with the heat conduction oil, so that the oil suction roller 4 can be cooled when the elastic strip 31 slides across the surface of the oil suction roller 4, and the effect of improving the cooling effect is achieved compared with the effect of only depending on the contact between the heat conduction plate 10 and the oil suction roller 4.

When the push rod 19 moves upwards, under the action of the third one-way valve 35, the space between the inner bottom wall of the mounting sleeve 16 and the elastic membrane 20 absorbs gas from the heat-insulating sleeve, because the gas with higher temperature in the thermal insulation sleeve is positioned on the inner top wall of the thermal insulation sleeve, the gas with higher temperature is absorbed into the space between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 through the third one-way valve 35 to cool the gas with higher temperature, when the push rod 19 moves down and the elastic membrane 20 is restored, the gas having a lower temperature between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 flows into the rotary sprayer 34 through the communication pipe 33, at this time, the rotary nozzle 34 is rotated rapidly, so that the gas sprayed therein at a relatively low temperature is diffused throughout the mounting sleeve 16, thereby can be for the cooling of whole installation cover 16, consequently the roller 4 that absorbs oil will be in the low temperature environment to the effect of the cooling effect of the roller 4 that absorbs oil has been played and has been improved. And when the air current passes through the third check valve 35, the space formed between the elastic membrane 20 and the inner bottom wall of the mounting sleeve 16 can be constantly pressurized, which serves to ensure that the push rod 19 can smoothly move upward.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto.
