To prevent oil from flowing into downstream rivers and threatening environmental safety, regular manual cleaning of the oil is required. If the oil is not completely cleaned, it will affect the safety of downstream water quality. Because the water collection well is a confined space, manual cleaning is highly dangerous, labor-intensive, and produces unsatisfactory cleaning results. To this end, the present application provides a water collection well oil cleaning system and method. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention designs a water collection well oil pollution cleaning system and method.

[0004] The present invention is realized by the following technical solutions: a water collection well oil pollution cleaning system,

[0005] Several in-well cameras are arranged in different areas on the wall of the water collection well to obtain image information of oil pollution on the water surface of the water collection well;

[0006] The oil collecting device comprises a floating frame arranged along the circumference of the well wall of the water collecting well, an oil separator connected to two opposite sides of the floating frame to separate the internal space of the floating frame from the oil collecting channel, and an oil blowing mechanism arranged on the floating frame and opposite to the oil collecting channel; the oil blowing mechanism is used to blow oil into the oil collecting channel;

[0007] The central controller is used to obtain image information sent by the camera in the well, and obtain the oil pollution area and the location area information of the oil pollution in the water collection well based on the image information, and determine whether to start the oil blowing mechanism based on the oil pollution area information;

[0008] The pollution-cleaning vessel communicates with the central controller and is used to clean the oil inside or outside the oil collection channel according to the control instructions of the central controller; the pollution-cleaning vessel is provided with a manipulator and a ship-end camera respectively connected to the sub-controller, and the sub-controller is also connected to the propulsion system of the pollution-cleaning vessel.

[0009] The oil separation mechanism includes mounting beams connected to opposite sides of the floating frame and a plurality of oil separation components arranged on the mounting beams; the oil separation components include triangular oil guide blocks and oil baffle blocks, the triangular oil guide blocks and oil baffle blocks are arranged front and back, and the oil baffle blocks are located close to the oil collecting channel; any tip of the triangular oil guide block faces the oil blowing mechanism, and an oil-passing gap is formed between the triangular oil guide blocks of two adjacent oil separation mechanisms; an oil baffle plane and an arc-shaped oil guide surface are provided on the triangular oil guide block, the oil baffle plane faces the oil collecting channel, and the arc-shaped oil guide surface extends to the rear of the triangular oil guide block of the adjacent oil separation mechanism.

[0010] The oil blowing mechanism includes an air blowing pipe arranged on the floating frame and an air blowing pump connected to the air blowing pipe, and the air blowing pump is connected to the central controller; the air blowing pipe is provided with a plurality of air jets facing the oil collecting channel.

[0011] The present invention also discloses an oil pollution cleaning method based on the above-mentioned water collection well oil pollution cleaning system, comprising the following steps:

[0012] Step 1: The cameras in each numbered well acquire the water surface image information of the corresponding area in the water collection well in real time and transmit the image information to the central controller;

[0013] Step 2: The central controller determines whether there is oil on the water surface based on the image information of each area; if there is oil on the water surface, the central controller calculates the area of ​​the oil stain and determines whether the area of ​​the oil stain is greater than or equal to a set first threshold; if it is greater than or equal to the first threshold, step 3 is executed; if it is less than the first threshold, the central controller further determines whether the oil stain is greater than or equal to a set second threshold; if it is greater than or equal to the second threshold, step 4 is executed; if it is less than the second threshold, step 5 is executed;

[0014] Step 3: The central controller activates the air pump, and the oil blowing mechanism blows air to blow the oil on the water surface into the oil collection channel. The central controller sends a command to the sub-controller on the pollution cleaning vessel, which sends a signal to the propulsion system to move the pollution cleaning vessel closer to the oil collection channel. The sub-controller controls the robotic gripper to take the oil absorbing paper from the pollution cleaning vessel and place it into the oil collection channel. The sub-controller controls the pollution cleaning vessel to move back and forth along the oil collection channel, allowing the oil absorbing paper to absorb the oil in the oil collection channel.

The sub-controller controls the robotic gripper to take the oil-absorbing paper from the pollution-cleaning vessel and place it on the water surface in the area. The pollution-cleaning vessel is then driven back and forth in the area, allowing the oil-absorbing paper to absorb the oil on the water surface. The ship-side camera captures the oil pollution information and sends it to the sub-controller. The sub-controller determines whether there is still oil pollution in the area. If so, it controls the pollution-cleaning vessel to continue to sail back and forth in the area. If not, it controls the pollution-cleaning vessel to return.

[0016] Step 5: The central controller sends a command to the sub-controller on the pollution-cleaning vessel, which sends a signal to the propulsion system to make the pollution-cleaning vessel sail to the oil-staining area; the sub-controller controls the robotic gripper to take the oil-dissolving powder on the pollution-cleaning vessel and throw it into the oil-staining area.

[0017] The first threshold is greater than the second threshold.

[0018] Step 3 also includes: after each round trip of the pollution cleaning ship, the sub-controller controls the manipulator to place the oil-absorbing paper after absorbing the oil into the waste paper bin on the pollution cleaning ship, and grabs new oil-absorbing paper to absorb the remaining oil.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Example

[0032] This embodiment discloses a water collection well oil pollution cleaning system, which includes: an in-well camera, an oil collection device, a central controller and a pollution cleaning vessel.

[0033] Among them, there are multiple cameras in the well, and they are numbered in sequence. The cameras in the well are arranged in different areas on the wall of the water collection well to obtain image information of oil pollution on the water surface in the water collection well; for example, the camera in well No. 1 corresponds to area No. 1 in the water collection well, and it collects water surface image information of area No. 1.

[0034] like Figure 2 As shown, the oil collection system includes a floating frame 1, an oil separator, and an oil blowing mechanism. The floating frame 1 is laid circumferentially along the wall of the water collection well. Made of foam, it floats on the water surface. The oil separator is attached to opposite sides of the floating frame 1, separating the interior of the frame into a narrow oil collection channel 3. The oil blowing mechanism is located on the floating frame 1, facing the oil collection channel 3, and is used to blow oil on the water surface into the channel 3.

[0035] Specifically, such as Figure 3 As shown, the oil separator mechanism includes a mounting beam 2 connected to opposite sides of the floating frame 1 and a plurality of oil separator components arranged on the mounting beam 2; the mounting beam 2 is located below the water surface, and at least a portion of the oil separator components is located above the water surface.

[0036] The oil separator assembly includes a triangular oil guide block 6 and an oil baffle block 7. These blocks are positioned one behind the other, with the block 7 positioned near the oil collection channel 3. Either tip of the triangular oil guide block 6 faces the oil blowing mechanism, creating an oil-passing gap between the triangular oil guide blocks 6 of two adjacent oil separator mechanisms. The triangular oil guide block 6 is provided with an oil baffle plane 8 and an arcuate oil guide surface 4. The oil baffle plane 8 faces the oil collection channel 3, while the arcuate oil guide surface 4 extends behind the triangular oil guide block 6 of the adjacent oil separator mechanism.

[0037] With the above structure, when the oil blowing mechanism blows the oil into the oil collecting channel 3, the oil first encounters the tips of the triangular oil guide blocks 6, where it is guided to the sides and passes through the oil-passing gap between two adjacent triangular oil guide blocks 6. The oil then encounters the curved oil guide surface 4 and flows along it into the oil collecting channel 3. The oil in the oil collecting channel 3 is blocked by the oil-blocking plane 8 and the triangular oil guide blocks 6, and its tension prevents it from flowing back out of the channel 3.

[0038] In addition, the oil blowing mechanism includes an air blowing pipe 5 fixed to the floating frame 1 and an air blowing pump connected to the air blowing pipe 5. The air blowing pipe 5 is provided with a plurality of air nozzles facing the oil collecting channel 3. When the air blowing pump is started, gas is blown out from the air nozzles, blowing the oil in the water collection well into the oil collecting channel 3.

[0039] The central controller is arranged outside the water collection well and is electrically connected to the camera and the air blow pump inside the well. It is used to obtain image information sent by the camera inside the well, and obtain the oil pollution area in the water collection well and the location area information of the oil pollution in the water collection well based on the image information, and determine whether to start the oil blowing mechanism based on the oil pollution area information.

[0040] The pollution cleaning vessel is equipped with a sub-controller, a manipulator and a ship-side camera connected to the sub-controller, and the sub-controller is also connected to the propulsion system of the pollution cleaning vessel. The central controller is connected to a first communication module, and the sub-controller is connected to a second communication module. The central controller and the sub-controller are connected through the first and second communication modules. Figure 1 The oil cleaning vessel is used to clean the oil inside or outside the oil collecting channel 3 according to the control instructions of the central controller.

[0041] In addition, the pollution-cleaning vessel is also equipped with an oil-absorbing paper storage bin, an oil-absorbing paper recovery bin and a deoiling powder storage bin, and oil-absorbing paper is placed in the oil-absorbing paper storage bin.

[0042] The oil pollution cleaning method based on the above-mentioned water collection well oil pollution cleaning system includes the following steps:

[0043] Step 1: The cameras in each numbered well acquire the water surface image information of the corresponding area in the water collection well in real time and transmit the image information to the central controller.

[0044] Step 2: The central controller determines whether there is oil on the water surface based on the received image information of each area; if there is oil on the water surface, the central controller further calculates the area of ​​the oil pollution and determines whether the area of ​​the oil pollution is greater than or equal to the set first threshold; if it is greater than or equal to the first threshold, execute step 3; if it is less than the first threshold, further determine whether the oil pollution is greater than or equal to the set second threshold; if it is greater than or equal to the second threshold, execute step 4; if it is less than the second threshold, execute step 5.

[0045] Specifically, the existing identification method can be used to identify the oil pollution area on the water surface. For example, the camera in the well may include an infrared camera and a color camera. The infrared camera and the color camera respectively capture images within the area. The central controller identifies the relative area ratios of the oil pollution images of the infrared camera and the color camera to determine the oil pollution area in the area. Of course, other existing algorithms can also be used to calculate the oil pollution area, which will not be described in detail.

[0046] In addition, the set first threshold is greater than the second threshold. When the oil pollution area is greater than the first threshold, it means that the amount of oil pollution in the water collection well is large, and the cleaning method in step 3 is adopted at this time; when the oil pollution area is greater than or equal to the second threshold and less than the first threshold, it means that the amount of oil pollution in the water collection well is small, and the cleaning method in step 4 is adopted at this time; when the oil pollution area is less than the second threshold, it means that the amount of oil pollution in the water collection well is very small, and the cleaning method in step 5 is adopted at this time.

[0047] The central controller can confirm which area of ​​the water surface has oil by identifying the image information of the cameras in each numbered well. For example, if there is oil in the image taken by the camera in well No. 1, it means that there is oil in area No. 1 in the collection well.

[0048] Step 3: When the oil spill area is greater than or equal to the first threshold, the central controller activates the air blower, and the oil blowing mechanism blows air to blow the oil spill from the water surface into the oil collection channel 3. Next, the central controller sends a command to the sub-controller on the pollution-cleaning vessel, which sends a signal to the propulsion system to move the pollution-cleaning vessel closer to the oil collection channel 3. The sub-controller controls the robotic gripper to take the oil-absorbing paper from the pollution-cleaning vessel and place it into the oil collection channel 3. The sub-controller then controls the pollution-cleaning vessel to move back and forth along the oil collection channel 3, allowing the oil-absorbing paper to absorb the oil spill in the oil collection channel 3. Simultaneously, the ship-side camera captures images of the oil collection channel 3 and sends them to the sub-controller. Based on the images, the sub-controller determines whether there is still oil spill in the oil collection channel 3. If so, the sub-controller controls the pollution-cleaning vessel to continue moving back and forth along the oil collection channel 3. If not, the sub-controller controls the pollution-cleaning vessel to return.

[0049] In this case, due to the high volume of oil, after each round trip, the sub-controller controls the robot to place the absorbed oil-absorbing paper into the waste paper bin on the cleaning vessel and then pick up new oil-absorbing paper to absorb the remaining oil. This embodiment, when the amount of oil is high, collects the oil in the oil collection channel 3 before cleaning it, making the cleaning more thorough and efficient.

[0050] Step 4: When the amount of oil in the sump is low, the central controller sends a command to the sub-controller on the cleanup vessel. The sub-controller sends a signal to the propulsion system, directing the cleanup vessel to the oil-stained area. For example, if the oil is in Area 1, the cleanup vessel will proceed to Area 1. The sub-controller then controls the robotic gripper to remove oil-absorbing paper from the cleanup vessel and place it on the surface of the water in that area. The cleanup vessel then drives back and forth across the surface, allowing the paper to absorb the oil. Simultaneously, the onboard camera captures oil information and sends it to the sub-controller. The sub-controller determines whether there is still oil in the area. If so, the cleanup vessel continues to move back and forth across the area. If not, the cleanup vessel returns. In other words, when the amount of oil is low, the cleanup vessel is directed to clean the area directly, without collecting the oil in the oil collection channel.

[0051] Step 5: When the amount of oil in the sump is very small, the central controller sends a command to the sub-controller on the cleaning vessel, which sends a signal to the propulsion system to make the cleaning vessel sail to the oily area. The sub-controller controls the robotic gripper to take the oil dissolving powder from the cleaning vessel and throw it into the oily area, using the oil dissolving powder to clean the oil.

[0052] This embodiment can automatically detect oil pollution in the water collection well and automatically clean up the oil pollution by controlling the oil cleaning ship. Compared with the method of cleaning by workers, its cleaning efficiency is higher and the operation is safer. At the same time, this embodiment combines multiple cleaning methods to further improve the efficiency of oil pollution cleaning.

[0053] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
