Moreover, the conventional water surface oil slick cleaning equipment (such as an oil collection ship) is generally large, and is difficult to operate in some narrow water areas or complex environments, which affects the cleaning efficiency. In addition, the current water surface oil slick cleaning technology has a narrow application range, mainly due to its specific operation object and cleaning environment, so that the cleaning equipment often cannot completely clean the oil slick floating on the water surface, and even the power waste discharged or the chemical treatment agent discharged during cleaning of the oil slick can cause secondary pollution to the water body. In addition to the above problems, the current water surface oil slick cleaning equipment often has a single function, and is mainly applied to cleaning of oil slick in marine and river water environments, and lacks other functions such as being used as a buoy for channel or position guidance.

DETAILED DESCRIPTION

[0037] The principles and characteristics of the present application are described below in combination with the accompanying drawings and specific embodiments, and the examples are only used to explain the present application and are not used to limit the scope of the present application.

[0038] In the description of the present application, if terms indicating orientation or position relationship such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer" and the like are used, the indicated orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the indicated device or element to have a specific orientation, to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0039] As Figures 1 to 6As shown, the present application provides a floating oil cleaning chain, which is formed by connecting a plurality of floating oil cleaning devices 100 in series by ropes or chains 200. Each of the floating oil cleaning devices 100 comprises a ring-shaped floating body 101 and a device body 102. The ring-shaped floating body 101 is connected to the device body 102 so that the device body 102 floats on the water surface. The device body 102 comprises an oil collecting bin 1, a ring-shaped bin cover 2, an oil collecting funnel 3, a hydrophobic oil-absorbing sponge body 4, a controller 5, and a cruise obstacle-avoiding vision module, an oil stain detection vision module, a punch oil-extruding power module, a cruise power module, a communication module, and an energy module electrically connected to the controller 5. The ring-shaped bin cover 2 is connected to the top of the oil collecting bin 1. The oil collecting funnel 3 is arranged at the ring-shaped bin cover 2. The hydrophobic oil-absorbing sponge body 4 is arranged in the oil collecting funnel 3. When the punch oil-extruding power module is started, the hydrophobic oil-absorbing sponge body 4 below can be repeatedly punched to extrude the adsorbed floating oil and enter the oil collecting bin 1 through the oil collecting funnel 3. The bottoms of the oil collecting bins 1 of two adjacent floating oil cleaning devices 100 are connected by a hose 6. At least one of the floating oil cleaning devices 100 has an oil pumping pipe. One end of the oil pumping pipe is inserted into the oil collecting bin 1 and close to the bottom of the oil collecting bin 1. The other end of the oil pumping pipe is provided with a joint for detachable connection with an oil product recovery pipeline. An oil pumping pump is arranged on the oil product recovery pipeline.

[0040] It should be noted that each floating oil cleaning device is provided with a structure for connecting the chain or rope, such as a locking hook or a rope ring, so as to connect adjacent floating oil cleaning devices by the chain or rope. After the floating oil cleaning device is put into the water body, the whole device floats above the water surface. The position of the top surface of the hydrophobic oil-absorbing sponge body is basically level with or slightly higher than the floating oil layer of the water surface. At the same time, due to the horizontal movement of the floating oil device, the action of the wave, and the action of the punch oil-extruding mechanism, a vortex is easily generated in the ring of the ring-shaped floating body, so as to ensure that the hydrophobic oil-absorbing sponge body effectively contacts the oil stain and autonomously absorbs it. The hydrophobic oil-absorbing sponge body has the characteristic of only absorbing oil but not absorbing water. After a certain interval (the interval of the action of the punch oil-extruding power module can be set), after the hydrophobic oil-absorbing sponge body absorbs an appropriate amount of floating oil, the punch oil-extruding power mechanism is actuated to extrude the hydrophobic oil-absorbing sponge body downward at the central upper surface, and the periphery of the hydrophobic oil-absorbing sponge body is lifted upward to move away from the water surface. This can not only ensure that the floating oil is extruded to enter the oil collecting bin through the hole of the oil collecting funnel for collection, but also effectively avoid water entering the oil collecting bin during the extrusion process. The floating oil cleaning chain of the present application can clean the oil layer with a thickness of less than 1 mm.

[0041] In an embodiment of the present application, as shown in FIG. 1, Figure 2 and 3As shown, the annular cover 2 is connected to the top of the oil collection tank 1 and is fixedly connected to the annular float 101 around its perimeter by outwardly extending connectors 7. The stamping and squeezing power module is fixed above the annular cover 2 by multiple spaced columns 14. The connectors include annular clamps and horizontal connecting rods. One end of the horizontal connecting rod is fixedly connected to the side of the annular cover, and the other end is connected to the annular clamp. The annular clamp is fitted and tightened onto the annular float.

[0042] In one embodiment of the present invention, one end of the oil recovery pipe extends into the oil recovery pool, and the other end is detachably connected to the oil extraction pipe. The oil recovery pool is located on an oil recovery vessel or a shore dock. The lowest point of the bottom wall of the oil collection tank 1 is provided with a connector pipe for connecting the hose 6. The connector pipe communicates with the interior of the oil collection tank 1. One end of the connector pipe connected to the hose 6 is detachably connected with an end cap. When it is necessary to connect the hose 6, the end cap must be removed first.

[0043] Among them, the hoses connecting the bottoms of two adjacent oil collection tanks are as follows: Figure 4 As shown, the connector pipe is a T-shaped pipe, with one port connected to the bottom of the oil collection tank, and the other two ports each connected to a flexible hose, thus connecting to the bottoms of both the front and rear oil collection tanks. The flexible hoses act as a communicating vessel, ensuring that the liquid oil level in each oil collection tank is maintained at approximately the same height, thereby avoiding the unfavorable situation where some oil collection tanks are full while others are only half full or less.

[0044] In one embodiment of the present invention, such as Figure 3 As shown, the stamping and extrusion power module includes a top cover 8, a motor 9, an eccentric wheel 11, a crank rod 12, and an extrusion rod 13. The bottom surface of the top cover 8 is fixedly connected to the annular cover 2 below via multiple spaced columns 14. Parallel and spaced fixing plates 10 are fixed to the upper surface of the top cover 8. The motor 9 is fixed to the outside of one of the fixing plates 10. The eccentric wheel 11 is located between two fixing plates 10. The center of the eccentric wheel 11 is fixedly connected to the output end of the motor 9. The spindle 11 is hinged to one end of the crank rod 12 via a connecting post at the eccentric position. The other end of the crank rod 12 is hinged to the upper end of the extrusion rod 13. The extrusion rod 13 passes through the fixed sleeve set in the center of the top cover 8 and is fixedly connected to the punch head below (not shown in the figure). When the motor 9 is started, the extrusion rod 13 moves up and down reciprocally within the fixed sleeve. The controller 5, the cruise obstacle avoidance vision module, the oil stain detection vision module, the communication module, and the energy module are all located on the upper surface of the top cover 8.

[0045] It can be understood that the stamping oil squeezing power module actually uses a motor to drive a crank rocker mechanism to make the stamping head reciprocate in the vertical direction to press the hydrophobic oil-absorbing sponge body below. The eccentric wheel can also be replaced by a cam or a crank. After the stamping head leaves the hydrophobic oil-absorbing cotton, it can automatically rebound to restore its shape. The hydrophobic oil-absorbing sponge body is a sponge block made of hydrophobic oil-absorbing material, which has the characteristics of hydrophobicity and oil absorption. When water and oil pass through the surface at the same time, the oil is actively absorbed and stored, while the water is not absorbed.

[0046] In one embodiment of the present application, as shown in Figure 3 The energy module includes a lithium battery 15 and a solar panel 16. The lithium battery 15 is fixed to the upper surface of the ring-shaped cover 2, and a cover shell 17 is provided on the ring-shaped cover 2. The solar panel 16 is fixed to the upper surface of the cover shell 17 and is electrically connected to the lithium battery 15 through a charging circuit. The cover shell can protect the components on the upper surface of the top cover from being damaged by wind, rain, or wave impact. The solar panel can charge the power supply using solar energy, increasing the endurance of the device. In addition to charging using the solar panel, the lithium battery can also be charged using mains power. The charging interface is located at a suitable position on the device body, and a waterproof cover can be provided at the charging interface. The oil collection tank is preferably hemispherical, and the cover shell is also hemispherical. The device body as a whole has a spherical shape, which is more aesthetically pleasing.

[0047] In one embodiment of the present application, the cruise obstacle avoidance vision module and the oil spill detection vision module each include a plurality of cameras mounted on the device body 102. The cruise power module includes a plurality of propellers 18 connected to the ring-shaped float 101 and capable of moving the ring-shaped float 101 on the water surface. The communication module uses wireless communication and includes a GPS locator.

[0048] It should be noted that the cameras of the cruise obstacle avoidance vision module and the oil spill detection vision module are not shown in the figure, but for those skilled in the art, the positions of the cameras can be selected and installed according to experience. Each floating oil cleaning device preferably has two propellers located below the water surface. Each propeller can be independently controlled in terms of start, stop, and speed, thereby enabling the floating oil cleaning device to move forward, backward, and turn, facilitating obstacle avoidance and smooth arrival at the location of the floating oil. The communication module uses wireless communication and includes a GPS locator, which is beneficial for positioning, navigation, and automatic return functions, and can also prevent the loss of the position of the floating oil cleaning chain.

[0049] The present application also provides a floating oil cleaning method, as shown in Figure 7 and 8 which uses the above-mentioned floating oil cleaning chain to clean the thin layer of floating oil on the surface of the water body, comprising the following steps:

[0050] S1. Advancement and Oil Slick Collection and Cleanup: The oil slick cleanup chain is deployed from the shore or hull into the water body relatively close to the oil slick area. The communication module provides the oil slick cleanup chain with the initial position information of the oil slick area. The oil slick cleanup chain automatically moves to the oil slick area by relying on the cruise power module and the cruise obstacle avoidance vision module. When it is about to reach the oil slick area, the oil pollution detection vision module is activated. When the oil pollution detection vision module detects the oil slick on the water surface, the oil slick cleanup chain advances in an encircling manner. At the same time as it advances, the ramming and squeezing oil power module is activated to collect the oil slick.

[0051] S2. Return trip and oil recovery: When the oil level in the oil collection tank 1 reaches the set height (a level gauge or level switch can be installed in the oil collection tank), the pumping and squeezing power module is shut down, and the communication module automatically records the current position so that it can return after the oil is emptied. At the same time, the communication module provides the floating oil cleaning chain with the location information of the oil recovery ship or dock with the oil recovery pool. The floating oil cleaning chain relies on the cruise power module and the cruise obstacle avoidance vision module to return to the oil recovery ship or dock on its own, connect the oil extraction pipe to the oil recovery pipeline, start the oil extraction pump, and pump the oil in the oil collection tank 1 into the oil recovery pool.

[0052] S3. Repeat until cleaning is complete: After all the oil in each oil collection tank 1 of the oil spill cleaning chain has been pumped to the oil recovery pool, the oil spill cleaning chain sets off again to the oil spill area according to the current position information recorded by the communication module, repeating S1 and S2 actions until the oil pollution detection vision module can no longer detect oil on the water surface in the oil spill area. Then the oil spill cleaning chain returns to the oil recovery ship or dock and no longer goes to the oil spill area. The oil spill cleaning is complete.

[0053] Based on the above method, when the oil spill cleaning chain in S1 advances in an enclosed manner, it gradually moves inward from the edge of the oil spill area. Each time, the oil spill cleaning chain encloses all or part of the oil spill area. After enclosing, each oil spill cleaning device 100 in the oil spill cleaning chain moves inward into the enclosed area in a set manner to shrink the enclosed area. During this process, oil spill collection and cleaning are achieved.

[0054] The present invention also provides a control method, such as Figure 9As shown, the operation of the floating oil cleaning chain is controlled as follows: first, each floating oil cleaning device 100 in the floating oil cleaning chain is started, then a predetermined position signal is sent to the communication module, the communication module transmits the received predetermined position signal to the controller 5, the controller 5 plans a path, and then sends corresponding electrical signals to the cruise obstacle avoidance vision module and the cruise power module to guide the floating oil cleaning chain to travel to the predetermined position. In the process of traveling, the oil pollution detection module keeps normal operation. If the oil pollution detection module detects oil pollution during operation, the oil pollution detection module feeds back a signal to the controller 5, and the controller 5 starts the stamping and oil extraction power module to collect oil pollution. When the oil pollution in the oil collection tank 1 reaches a set height, the oil pollution detection module feeds back a signal to the controller 5 again, and the controller 5 immediately sends a signal to the cruise obstacle avoidance vision module and the cruise power module. The floating oil cleaning chain returns to the oil product recovery ship or the wharf provided with the oil product collection tank to extract and recover the oil product. After the extraction is completed, the floating oil cleaning chain goes to the floating oil area again, and the cycle is repeated until the cleaning is completed.

[0055] On the basis of the above control method, when the floating oil cleaning chain goes to the predetermined position or returns, each floating oil cleaning device 100 is arranged in a straight line and consistent with the forward direction.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

7. A method for cleaning up floating oil, characterized in that, The method of cleaning a thin layer of floating oil on the surface of a water body using the oil spill cleaning chain according to any one of claims 1 to 6 includes the following steps: S1. Advancement and Oil Slick Collection and Cleanup: The oil slick cleanup chain is deployed from the shore or hull into the water body relatively close to the oil slick area. The communication module provides the oil slick cleanup chain with the initial position information of the oil slick area. The oil slick cleanup chain automatically moves to the oil slick area by relying on the cruise power module and the cruise obstacle avoidance vision module. When it is about to reach the oil slick area, the oil pollution detection vision module is activated. When the oil pollution detection vision module detects the oil slick on the water surface, the oil slick cleanup chain advances in an encircling manner. At the same time as it advances, the ramming and squeezing oil power module is activated to collect the oil slick. S2. Return trip and oil recovery: When the oil level in the oil collection tank (1) reaches the set height, the pressurizing and squeezing power module is shut down, and the communication module automatically records the current position so that the oil can be discharged and returned. At the same time, the communication module provides the floating oil cleaning chain with the location information of the oil recovery ship or dock with the oil recovery pool. The floating oil cleaning chain relies on the cruise power module and the cruise obstacle avoidance vision module to return to the oil recovery ship or dock, connect the oil pumping pipe to the oil recovery pipeline, start the oil pumping pump, and pump the oil in the oil collection tank (1) into the oil recovery pool. S3. Repeat until cleaning is complete: After all the oil in each oil collection tank (1) of the oil spill cleaning chain is pumped to the oil recovery pool, the oil spill cleaning chain sets off again to the oil spill area according to the current position information recorded by the communication module, repeating S1 and S2 actions until the oil pollution detection vision module can no longer detect oil on the water surface in the oil spill area. Then the oil spill cleaning chain returns to the oil recovery ship or dock and no longer goes to the oil spill area. The oil spill cleaning is completed.

8. The method for cleaning up floating oil according to claim 7, characterized in that, When the oil spill cleaning chain in S1 advances in an enclosed manner, it gradually moves inward from the edge of the oil spill area. Each time, the oil spill cleaning chain encloses all or part of the oil spill area. After enclosing, each oil spill cleaning device (100) in the oil spill cleaning chain moves inward into the enclosed area in a set manner to shrink the enclosed area. During this process, oil spill collection and cleaning are achieved.

9. A control method for controlling the operation of the oil spill cleanup chain according to any one of claims 1 to 6, characterized in that, First, each oil cleaning device (100) in the oil cleaning chain is started up, and then a predetermined position signal is sent to the communication module. The communication module transmits the received predetermined position signal to the controller (5). After the controller (5) plans the path, it sends corresponding electrical signals to the cruise obstacle avoidance vision module and the cruise power module to guide the oil cleaning chain to the predetermined position. During this journey, the oil pollution detection module maintains normal operation. If the oil pollution detection module detects oil pollution during the journey, it sends a signal back to the controller (5). The controller (5) starts the stamping and squeezing power module to start collecting oil pollution. When the oil pollution in the oil collection tank (1) reaches the set height, the oil pollution detection module sends a signal back to the controller (5). The controller (5) immediately sends a signal to the cruise obstacle avoidance vision module and the cruise power module. The oil cleaning chain returns to the oil recovery ship or dock with an oil collection pool for oil extraction and recovery. After extraction, the oil cleaning chain goes to the oil area again and repeats the cycle until the cleaning is completed.

10. The control method according to claim 9, characterized in that, When the oil spill cleanup chain is heading to the designated location or returning, the oil spill cleanup devices (100) are arranged in a straight line and in the same direction of travel.
