Description

[0001] The invention relates to the field of water surface cleaning, in particular to a water surface oil pollution cleaning ship. Background Art

[0002] In recent years, with the acceleration of urbanization, people's requirements for water surface environment are getting higher and higher. When encountering heavy rainfall, mixed water bodies containing kitchen grease, ground sediment pollutants and oil pollution in the pipe network can easily exceed the carrying capacity of sewage treatment facilities and be directly discharged into urban rivers through flood discharge channels. When such oil-rich sewage enters open waters, it will form a large area of ​​surface oil film pollution, which not only damages the ecological environment of the water body, but also seriously affects the quality of life of coastal residents due to its continuous odor. At present, conventional emergency treatment methods mainly use two methods: chemical dispersant decomposition or lipophilic adsorption material collection: although the former can temporarily eliminate visual pollution, it will cause secondary pollution of the water body and accelerate the dissolution and diffusion of oil substances; although the latter can realize the physical recovery of pollutants, there are problems such as large consumption of adsorption media, low efficiency of manual salvage and high operating costs. Especially in special operating environments such as narrow urban rivers, there is still a lack of relevant equipment that can independently complete oil pollution collection. Therefore, how to design an oil pollution collection equipment that does not cause secondary pollution of chemical agents, has low cost and high salvage efficiency has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] Based on this, in order to solve the above problems, the present invention provides a surface oil pollution cleaning ship comprising: a first oil pollution treatment tank, a collecting port, a second oil pollution treatment tank, an oil pollution storage tank and an oil pollution extraction device, the collecting port is connected with the first oil pollution treatment tank, an oil overflow plate is arranged between the second oil pollution treatment tank and the first oil pollution treatment tank, a first partition plate is arranged between the second oil pollution treatment tank and the oil pollution storage tank, the oil pollution extraction device comprises an oil pollution extraction pump, a first water inlet pipe and a first water outlet pipe, one end of the first water inlet pipe is connected with the water surface of the second oil pollution treatment tank, and the other end is connected with the oil pollution extraction pump, one end of the first water outlet pipe is connected with the oil pollution extraction pump, and the other end is connected with the oil pollution storage tank; wherein, the collecting port, the first oil pollution treatment tank, the second oil pollution treatment tank and the oil pollution storage tank are arranged on the hull in sequence.

[0004] With such a configuration, the sewage with oil pollution enters the first waste oil treatment tank through the collection port, the primary concentrated oil pollution pollution floating on the upper layer of the first waste oil treatment tank passes over the oil spill plate and enters the second waste oil treatment tank, and the secondary concentrated oil pollution pollution floating on the upper layer of the second waste oil treatment tank is extracted to the waste oil storage tank through the first water inlet pipe set on its water surface through the waste oil extraction pump and the first water outlet pipe. Since the density of oil is less than that of water, it floats on the surface of the water. After two-stage screening, the secondary concentrated oil pollution pollution in the waste oil storage tank has a higher oil content and can be centrally treated. In addition, the entire process uses a purely physical method to concentrate the oil pollution, which will not pollute the environment due to chemical agents, and does not use high-cost adsorption consumables. It can remove oil pollution on the water surface in an environmentally friendly, efficient and low-cost manner.

[0005] In one embodiment of the present invention, an oil spill gate capable of adjusting the oil spill height is provided on the oil spill plate.

[0006] With such arrangement, the oil spill plate can adjust the oil spill height according to the oil spill height in the first waste oil treatment tank, so that the oil spill floating on the water surface can just pass over the oil spill plate, while the water under the oil spill is blocked outside the second waste oil treatment tank, thereby improving the wastewater concentration efficiency and increasing the oil content of the primary concentrated oil wastewater in the second waste oil treatment tank.

[0007] In one embodiment of the present invention, the surface oil cleaning vessel further comprises a drainage door, which is rotatably arranged below the collection port to realize the opening and closing of the collection port, and a drainage plate is arranged in front of the first oil waste treatment tank.

[0008] With this arrangement, the drainage gate can close the collection port in the non-working state, reduce navigation resistance, and increase navigation speed, and can open the collection port in the working state. In addition, the rotationally arranged drainage gate can also change the opening and closing angle according to the depth of oil pollution in the water area, control the water flow and water depth, so that the oil pollution on the water surface can just pass over the drainage gate, and most of the water is blocked outside the drainage gate, thereby improving the concentration efficiency of sewage and increasing the oil content of sewage. The drainage plate provides a fixed position for the drainage gate and other components.

[0009] In one embodiment of the present invention, a first filter screen is arranged in the first waste oil treatment tank, and the surface oil cleaning vessel further comprises a drainage device, which is connected to the lower chamber separated by the first filter screen to discharge clean water out of the hull.

[0010] With this arrangement, the clean water with less oil content in the lower layer of the first waste oil treatment tank can be continuously discharged out of the hull by the drainage device, ensuring that the first waste oil treatment tank can continuously make room to receive the waste water entering from the collection port, so that the hull can continuously collect waste water and improve work efficiency. The first filter can filter the garbage mixed in the waste water to prevent it from blocking the drainage device or being discharged into the water again.

[0011] In one embodiment of the present invention, the clean water suction device includes a clean water suction pump, a second water inlet pipe, and a second water outlet pipe. One end of the second water inlet pipe is connected to the lower chamber separated by the second filter screen, and the other end is connected to the clean water suction pump. One end of the second water outlet pipe is connected to the clean water suction pump, and the other end is connected to the outside of the hull.

[0012] With such arrangement, the clean water suction device has a simple structure, low cost, and can reasonably utilize space for layout.

[0013] In one embodiment of the present invention, a second filter screen is arranged in the second waste oil treatment tank, and the surface oil cleaning vessel further comprises a clean water suction device, which is connected to the lower chamber separated by the second filter screen to discharge clean water out of the hull.

[0014] With such arrangement, the clean water with less oil content in the lower layer of the second waste oil treatment tank can be continuously discharged out of the hull by the clean water suction device, ensuring that the second waste oil treatment tank can continuously make room to receive the primary concentrated oily wastewater overflowing from the first waste oil treatment tank, so that the hull can continuously collect the wastewater and improve the work efficiency. The second filter can filter the garbage mixed in the primary concentrated oily wastewater to prevent it from blocking the clean water suction device or discharging it into the water again.

[0015] In one embodiment of the present invention, the surface oil cleaning ship also includes a drainage tank, a second partition plate is arranged between the waste oil storage tank and the drainage tank, the drainage tank is arranged in sequence behind the waste oil storage tank, the drainage device includes a drainage pipe, a drainage pump and a drain pipe, one end of the drainage pipe is connected to the lower chamber separated by the first filter screen, and the other end is connected to the drainage tank, the drainage pump is arranged in the drainage tank, one end of the drain pipe is connected to the drainage pump, and the other end is connected to the outside of the hull.

[0016] In this way, a separate drainage bin increases the installation space of the drainage pump, and a drainage pump with a higher power can be selected according to specific needs, which saves the space of the first waste oil treatment bin and can accommodate more sewage for treatment.

[0017] In one embodiment of the present invention, there are two drainage tubes, which are arranged at a certain distance from each other.

[0018] With such arrangement, the two drainage pipes increase the efficiency of pumping clean water, and are arranged at a certain distance to ensure the balance of water flow on both sides.

[0019] In one embodiment of the present invention, the first water inlet pipe is provided with a bell mouth.

[0020] In this way, the bell-mouth arrangement can increase the extraction area of ​​the oil on the surface of the second waste oil treatment bin and increase the oil extraction efficiency.

[0021] In one embodiment of the present invention, the surface oil cleaning vessel also includes an oil unloading device, which includes an oil inlet pipe, an oil unloading pump and an oil outlet pipe. One end of the oil inlet pipe is connected to the waste oil storage tank, and the other end is connected to the oil unloading pump. One end of the oil outlet pipe is connected to the oil unloading pump, and the other end is connected to a designated oil unloading point.

[0022] With this configuration, the oil unloading device can automatically transfer the collected secondary concentrated oil wastewater to the designated unloading point for centralized treatment, eliminating the need for manual unloading, thus increasing work efficiency. It can also cooperate with other assisting vessels to continue cleaning.

[0023] In one embodiment of the present invention, the surface oil cleaning ship also includes two traction robots, two fences and a propeller, one end of the two fences are respectively connected to the two sides of the collection port, and the other end is respectively connected to the two traction robots, and the propeller is arranged at the stern.

[0024] With this arrangement, the traction robot and fence can increase the sewage treatment area in the water area, can selectively treat the oily waters in a large area, and improve the collection efficiency.

The propeller increases the running speed of the ship when not in working state, and quickly reaches the designated oil unloading point.

[0025] In one embodiment of the present invention, the surface oil cleaning vessel is provided with a water filling valve at the bottom of the first waste oil treatment tank.

[0026] With this arrangement, when the surface oil cleaning ship sails to the designated waters, the water filling valve is opened, and water from the bottom of the hull is poured into the hull, increasing the draft of the entire hull. When the collection port reaches the appropriate position and the oil on the water surface can just pass over the drainage gate, the water filling valve can be closed. At this time, the hull is at a suitable draft, increasing the efficiency of oil collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-3 As shown, the present invention provides a surface oil pollution cleaning ship comprising: a first waste oil treatment tank 1, a collecting port 2, a second waste oil treatment tank 3, a waste oil storage tank 4, a waste oil extraction device 5 and a drainage door 6, the collecting port 2 is connected to the first waste oil treatment tank 1, an oil spill plate 11 is arranged between the second waste oil treatment tank 3 and the first waste oil treatment tank 1, a first partition plate 31 is arranged between the second waste oil treatment tank 3 and the waste oil storage tank 4, the waste oil extraction device 5 comprises a waste oil extraction pump 51, a first water inlet pipe 52 and The first water outlet pipe 53, one end of the first water inlet pipe 52 is connected to the water surface of the second waste oil treatment tank 3, and the other end is connected to the waste oil extraction pump 51, the first water outlet pipe 53 is connected to the waste oil extraction pump 51 at one end, and the other end is connected to the waste oil storage tank 4; wherein, the collecting port 2, the first waste oil treatment tank 1, the second waste oil treatment tank 3, and the waste oil storage tank 4 are arranged in sequence on the hull, the drainage door 6 is rotatably arranged below the collecting port 2 to realize the opening and closing of the collecting port 2, and a drainage plate 13 is arranged in front of the first waste oil treatment tank 1.

[0038] It should be noted that the oil spill plate 11 has an opening at the top, and its height is set according to the actual working conditions, so that the primary concentrated oily wastewater floating on the upper layer of the first waste oil treatment tank 1 can pass over the oil spill plate 11 and enter the second waste oil treatment tank 3 as much as possible, while the clean water below is blocked in the first waste oil treatment tank 1, and the first partition plate 31 separates the second waste oil treatment tank 3 and the waste oil storage tank 4 into two spaces, and the secondary concentrated oily wastewater of the second waste oil treatment tank 3 can only be extracted to the waste oil storage tank 4 through the waste oil extraction device 5.

[0039] It can be understood that the sewage with oil pollution enters the first waste oil treatment tank 1 through the collection port 2, the primary concentrated oil pollution pollution floating on the upper layer of the first waste oil treatment tank 1 passes over the oil spill plate 11 and enters the second waste oil treatment tank 3, and the secondary concentrated oil pollution pollution floating on the upper layer of the second waste oil treatment tank 3 is extracted to the waste oil storage tank 4 by the first water inlet pipe 52 set on its water surface through the waste oil extraction pump 51 and the first water outlet pipe 53. Since the density of oil is less than that of water, it floats on the surface of the water. After two-stage screening, the secondary concentrated oil pollution pollution in the waste oil storage tank 4 has a high oil content and can be centrally processed. In addition, the whole process uses a pure physical method to concentrate the oil pollution, which will not pollute the environment due to chemical agents, and does not use high-cost adsorption consumables. It can remove oil pollution on the water surface in an environmentally friendly, efficient and low-cost manner; the drainage gate 6 can close the collection port 2 in the non-working state to reduce the navigation resistance and increase the navigation speed, and the collection port 2 can be opened in the working state. In addition, the rotatable drainage gate 6 can also change the opening and closing angle according to the depth of the oil pollution in the water area, control the flow rate and depth of the water, so that the oil pollution on the water surface can just pass over the drainage gate 6, and most of the water is blocked outside the drainage gate 6, thereby improving the concentration efficiency of the sewage and increasing the oil content of the sewage. The drainage plate 13 provides a fixed position for the drainage gate 6 and other components.

[0040] Optionally, an oil spill gate 111 capable of adjusting the oil spill height is provided on the oil spill plate 11 .

[0041] It should be noted that the oil overflow door 111 can be rotatably arranged at the top of the oil overflow plate 11, and can also be moved up and down at the top of the oil overflow plate 11, and can be adjusted manually or automatically, and the present invention is not limited thereto.

[0042] It can be understood that the oil spill plate 11 can adjust the oil spill height according to the oil height of the first oil waste treatment tank 1, so that the oil floating on the water surface can just pass over the oil spill plate 11, and the water under the oil waste is blocked outside the second oil waste treatment tank 3, thereby improving the concentration efficiency of the sewage and increasing the oil content of the primary concentrated oil sewage in the second oil waste treatment tank 3.

[0043] Optionally, a first filter screen 12 is provided in the first waste oil treatment tank 1, and the surface oil cleaning ship further comprises a drainage device 7, which is connected to the lower chamber separated by the first filter screen 12 to discharge clean water out of the hull.

[0044] It should be noted that the first filter screen 12 can be set to various shapes as long as it can separate the first waste oil treatment tank 1 into upper and lower chambers, and the present invention is not limited here.

[0045] It can be understood that the clean water with less oil content in the lower layer of the first waste oil treatment tank 1 can be continuously discharged from the hull by the drainage device 7, ensuring that the first waste oil treatment tank 1 can continuously make room to receive the sewage entering from the collection port 2, so that the hull can continue to collect and improve work efficiency. The first filter 12 can filter the garbage mixed in the sewage to prevent it from blocking the drainage device or being discharged into the water again.

[0046] Optionally, a second filter screen 32 is provided in the second waste oil treatment tank 3, and the surface oil cleaning ship further comprises a clean water suction device 8, which is connected to the lower chamber separated by the second filter screen 32 to discharge clean water out of the hull.

[0047] It should be noted that the second filter screen 32 can be set to various shapes as long as it can separate the second waste oil treatment tank 3 into upper and lower chambers, and the present invention is not limited here.

[0048] It is understandable that the clean water with less oil content in the lower layer of the second waste oil treatment tank 3 can be continuously discharged from the hull by the clean water suction device 8, ensuring that the second waste oil treatment tank 3 can continuously make room to receive the primary concentrated oily wastewater overflowing from the first waste oil treatment tank 1, so that the hull can continuously collect and improve work efficiency. The second filter 32 can filter the garbage mixed in the primary concentrated oily wastewater to prevent it from blocking the clean water suction device 8 or discharging it into the water again.

[0049] Optionally, the clean water suction device 8 includes a clean water suction pump 81, a second water inlet pipe 82, and a second water outlet pipe 83, one end of the second water inlet pipe 82 is connected to the lower chamber separated by the second filter screen 32, and the other end is connected to the clean water suction pump 81, one end of the second water outlet pipe 83 is connected to the clean water suction pump 81, and the other end is connected to the outside of the hull.

[0050] It can be understood that the clean water suction device 8 has a simple structure, low cost, and can reasonably utilize space for layout.

[0051] Optionally, the surface oil cleaning ship also includes a drainage tank 9, a second partition plate 41 is arranged between the waste oil storage tank 4 and the drainage tank 9, the drainage tank 9 is arranged in sequence behind the waste oil storage tank 4, the drainage device 7 includes a drainage pipe 71, a drainage pump 72 and a drain pipe 73, one end of the drainage pipe 71 is connected to the lower chamber separated by the first filter screen 12, and the other end is connected to the drainage tank 9, the drainage pump 72 is arranged in the drainage tank 9, one end of the drain pipe 73 is connected to the drainage pump 72, and the other end is connected to the outside of the hull.

[0052] It should be noted that the second partition plate 41 separates the dirty oil storage bin 4 and the drainage bin 9 into two spaces, and the drainage pipe 71 is arranged through the second dirty oil treatment bin 3 and the bottom of the dirty oil storage bin 4 .

[0053] It is understandable that the separate provision of the drainage chamber 9 increases the installation space of the drainage pump 72. A drainage pump 72 with greater power can be selected according to specific needs, thereby saving space in the first waste oil treatment chamber 1 and accommodating more wastewater for treatment.

[0054] Optionally, there are two drainage tubes 71 , which are arranged at a certain distance from each other.

[0055] It can be understood that the two drainage pipes 71 increase the efficiency of pumping clean water, and are arranged at a certain distance to ensure the balance of water flow on both sides.

[0056] Optionally, the first water inlet pipe 52 is provided with a bell mouth 521 .

[0057] It can be understood that the provision of the bell mouth 521 can increase the extraction area of ​​the oil on the surface of the second waste oil treatment tank 3 and increase the oil extraction efficiency.

[0058] Optionally, the surface oil cleaning ship also includes an oil unloading device 10, which includes an oil inlet pipe 101, an oil unloading pump 102 and an oil outlet pipe 103. One end of the oil inlet pipe 101 is connected to the waste oil storage tank 4, and the other end is connected to the oil unloading pump 102. One end of the oil outlet pipe 103 is connected to the oil unloading pump 102, and the other end is connected to a designated oil unloading point.

[0059] It is understandable that the oil unloading device 10 can automatically transfer the collected secondary concentrated oil wastewater to a designated unloading point for centralized treatment, eliminating the need for manual unloading, thereby increasing work efficiency. It can also cooperate with other assisting vessels to continuously clean up.

[0060] Optionally, the surface oil cleaning ship also includes two traction robots 100, two fences 200 and a thruster 300, one end of the two fences 200 are respectively connected to the two sides of the collection port 2, and the other end is respectively connected to the two traction robots 100, and the thruster 300 is arranged at the stern.

[0061] It is understandable that the traction robot 100 and the fence 200 can increase the sewage treatment area of ​​the water area, can selectively treat the oily waters in a large area, and improve the collection efficiency. The traction robot 100 can also be used as a power source for the hull to move forward in the working state. The propeller 300 increases the running speed of the hull in the non-working state and quickly reaches the designated oil unloading point.

[0062] Optionally, the surface oil pollution cleaning ship is further provided with a water filling valve (not shown in the figure) at the bottom of the first waste oil treatment tank 1.

[0063] It can be understood that when the surface oil cleaning ship sails to the designated waters, the water filling valve is opened, and water from the bottom of the hull is poured into the hull, and the draft of the entire hull increases. When the collection port 2 reaches the appropriate position and the oil on the water surface can just pass over the drainage gate 6, the water filling valve can be closed. At this time, the hull is at a suitable draft depth, which increases the efficiency of oil collection.

[0064] Optionally, a cab can be arranged at the stern according to conventional needs, or unmanned operation can be selected. The surface garbage cleaning ship can be driven by electricity or engine, and all conventional equipment for navigation can be equipped.

[0065] The working process of the entire surface oil pollution cleaning ship is as follows: sail the surface oil pollution cleaning ship to the designated operating waters, turn off the propeller 300 to stop the hull. Then open the filling valve, open the drainage gate 6, so that the hull reaches a suitable draft, close the filling valve, and use the two traction robots 100 to pull the two fences 200 to spread out in an "eight" shape at the bow. The traction robot 100 pulls the hull to operate on the water surface, and adjusts the angle of the drainage gate 6 so that the surface oil can just pass the drainage gate 6. The surface oil flows through the fence 200 from the collection port 2 into the first waste oil treatment tank 1. As the oil on the upper layer of the first waste oil treatment tank 1 continues to accumulate, turn on the drainage pump 72 so that the clean water at the bottom of the first waste oil treatment tank 1 is continuously discharged from the hull body to adjust the oil spill. The height of the door 111 allows the floating primary concentrated oily wastewater on the upper layer of the first waste oil treatment tank 1 to pass over the oil overflow door 111 and enter the second waste oil treatment tank 3. As the oil on the upper layer of the second waste oil treatment tank 3 continues to accumulate, the clean water suction device 8 is turned on to continuously discharge the clean water at the bottom of the second waste oil treatment tank 3 out of the hull, and the waste oil extraction pump 51 is turned on to extract the secondary concentrated oily wastewater on the upper layer of the second waste oil treatment tank 3 to the waste oil storage tank 4. The secondary concentrated oily wastewater in the waste oil storage tank 4 is transported to the designated oil unloading point through the oil unloading pump 102. The designated oil unloading point can be on land or on a cooperating ship. After the operation is completed, the front traction robot 100 and the fence 200 are folded, the drainage door 6 is closed, and the drainage pump 72 continues to extract, and the remaining water in the first waste oil treatment tank 1 is continuously discharged. The draft of the hull becomes shallower and reaches a depth suitable for navigation. The drainage pump 72 is turned off and the propeller 300 is turned on for the return trip.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
