Description

Technical Field

[0001] The present invention relates to the field of environmental protection technologies, and particularly relates to a device for detecting and recovering oil spills on the river surface. Background Art

[0002] With the booming development of the waterborne transportation industry, water pollution problems, especially oil spill incidents on the river surface, have become environmental challenges that urgently need to be solved. Oil spills not only seriously threaten the aquatic ecosystem, but also affect drinking water safety, fishery resources, and human health.

[0003] In related technologies, the detection of oil spills on the river surface is mostly carried out by an oil pollution detector to monitor the oil spill situation on the river surface. For example, an ultraviolet fluorescence type non-contact oil pollution detector uses the principle of ultraviolet light-induced fluorescence to monitor the oil pollution on the water surface or the surface of an object. However, due to plant pigments, fluorite minerals, detergents, floating plastics, and other non-oil substances that can fluoresce, false positives will occur during detection, thereby affecting the detection accuracy of the oil pollution detector. In addition, traditional oil pollution detectors usually have an alarm device or a communication module built in. When oil leakage is detected, it can notify the inspection personnel in time for handling. Therefore, the spread of oil pollution is also affected by the response speed of the inspection personnel. In the initial stage of the oil spill, after the inspection personnel receive the oil spill notice and before they reach the incident site, the spread of the oil pollution on the river surface continues.

Detailed implementation manners

[0006] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention. The oil spill detection and recovery device on the river surface according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0007] As Figure 1 and Figure 2 shown, the oil spill detection and recovery device on the river surface according to the embodiment of the present invention may include an oil storage tank 100, a driving device 200, an oil pollution detector 300, a visual recognition and positioning system 400, an oil absorption device 500, an oil squeezing device 600, a solar panel 700 and a communication module (not shown in the figure). Among them, the driving device 200 is arranged on both sides of the oil storage tank 100, and a navigation system is built in the driving device 200. It should be noted that the navigation system can perform path planning based on the given position information and drive the oil storage tank 100 to the given position. The oil pollution detector 300 is arranged on the top of the oil storage tank 100. The visual recognition and positioning system 400 is electrically connected to the oil pollution detector 300 through a data fusion processor to obtain an oil pollution detection signal and oil pollution position information, transmit the oil pollution detection signal to the communication module, and transmit the oil pollution position information to the navigation system.

[0008] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 3 shown, the oil pollution detector 300 includes an installation cavity 310, a laser emitter 320, a multi-channel fluorescence receiver 330, and a control unit 340. Among them, the installation cavity 310 is arranged at the top of the oil storage tank 100. The laser emitter 320 and the multi-channel fluorescence receiver 330 are respectively arranged in the installation cavity 310 and are electrically connected to the control unit 340 respectively. It should be noted that when the oil pollution detector 300 detects oil pollution, the laser emitter 320 emits laser pulses, and the laser energy excites the molecules in the oil pollution to generate fluorescence. The multi-channel fluorescence receiver 330 captures the fluorescence signal and transmits the fluorescence signal into the control unit 340. The control unit 340 analyzes the fluorescence intensity and spectrum to determine the nature and distribution of the oil pollution, so as to generate a first oil pollution signal.

[0009] To clearly illustrate the previous embodiment, in an embodiment of the present invention, the visual recognition and positioning system 400 includes a high-definition probe, a processing unit, and a GPS locator. Among them, the high-definition probe is mounted on the oil pollution detector 300 through a mounting bracket, and the high-definition probe and the GPS locator are respectively connected to the processing unit. The processing unit calculates the oil pollution position information through the high-definition probe and in combination with the GPS locator. It should be noted that the high-definition probe has the characteristics of high resolution and wide angle, and can capture clear images even under low light conditions. The high-definition probe continuously shoots videos or captures static images, and these images include the details of the river surface, ground or other detection areas, and generate image data.

[0010] The processing unit analyzes the image data through image processing algorithms, which includes removing image noise, enhancing contrast, and using machine learning or deep learning models for visual recognition to automatically identify and mark the oil pollution features in the image, and identify the oil pollution forms such as oil films and floating oils through features such as color, texture, and shape, and compare with the preset oil pollution samples to further analyze and determine information such as the diffusion range and concentration of the oil pollution, so as to generate a second oil pollution signal. At the same time, the GPS locator provides its own accurate position information, and the processing unit calculates the position coordinates of the oil pollution to generate the oil pollution position information.

[0011] In an embodiment of the present invention, the data fusion processor fuses the first oil pollution signal of the fusion control unit 340 and the second oil pollution signal of the processing unit to obtain an oil pollution detection signal, and transmits the oil pollution position information to the navigation system. It should be noted that when only the oil pollution detector 300 is used for oil pollution detection, the information dimension is relatively single, that is, mainly relying on the fluorescence signal, providing limited information on the appearance characteristics and diffusion state of the oil pollution, and unable to verify and judge the fluorescence that may also be generated by non-oil pollution substances, which will cause false alarms and reduce the accuracy. In addition, if only the graphic recognition technology is used for oil pollution judgment, although the appearance characteristics of the oil pollution can be directly observed, the light conditions, water turbidity, water surface fluctuations, etc. may all affect the image quality, thereby affecting the recognition accuracy. Therefore, the first oil pollution signal in the oil pollution detector 300 and the second oil pollution signal in the visual recognition and positioning system 400 are subjected to data fusion, using multi-source information complementarity to improve the accuracy and integrity of the overall detection. Combining visual features and chemical characteristics, a more comprehensive assessment of the oil pollution can be carried out.

[0012] Specifically, as Figure 7 shown, when the oil storage tank 100 floats on the river surface, the oil pollution detector 300 detects the river surface. When an oil leakage event occurs, the laser pulse emitted by the laser emitter 320 irradiates the oil pollution, causing the oil pollution to emit fluorescence. Then, the multi-channel fluorescence receiver 330 detects the fluorescence signal and generates a first oil pollution signal. At the same time, the visual recognition and positioning system 400 performs visual analysis on the river surface in this area. The high-definition probe takes pictures of the river surface to generate picture information, and transmits the picture information to the processing unit for picture processing to generate a second oil pollution signal, and calculates the oil pollution position information of the oil leakage position in combination with the self-position signal emitted by the GPS locator. The data fusion processor fuses the first oil pollution signal and the second oil pollution signal to form a final oil pollution detection signal, and then transmits the oil pollution detection signal to the communication module to remind the inspection personnel. At the same time, the oil pollution position information is transmitted to the navigation system, and the driving device 200 drives the entire device to move forward to the position where the oil pollution occurs to complete the control of each component. The oil squeezing device 600 is connected to the top of the oil storage tank 100, the oil suction device 500 is arranged outside the oil storage tank 100, and the oil suction end of the oil suction device 500 passes through the extrusion end of the oil squeezing device 600. The solar panel 700 is arranged on the oil storage tank 100.

[0013] In an embodiment of the present invention, as Figure 4 shown, the oil suction device 500 includes a floating frame 510, a first guide wheel 520, a second guide wheel 530, and an oil suction cable 540. Among them, as Figure 6As shown in the figure, a vertical fixed rod 101 is provided at the front end of the oil storage tank 100. The floating frame 510 is slidably arranged on the fixed rod 101 and floats on the river surface. A roller 511 is provided at the end of the floating frame 510. Two first guide wheels 520 are respectively arranged on both sides of the oil storage tank 100, and two second guide wheels 530 are respectively arranged above the corresponding first guide wheels 520. The oil absorption cable 540 is a closed annular cable and is arranged on the roller 511, the two first guide wheels 520 and the two second guide wheels 530.

[0014] It should be noted that the floating frame 510 floats on the river surface to carry the oil absorption cable 540 for floating. The oil on the river surface can be adsorbed through the oil absorption cable 540. Among them, the oil absorption cable 540 is a product specially designed to quickly absorb oils and other oil-based liquids without absorbing water. Therefore, it has a wide range of applications in the fields of oil spill treatment, environmental protection cleaning, industrial maintenance and emergency response.

[0015] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 5 shown, the oil squeezing device 600 includes a feed hopper 610, a pressure roller 620, a gear 630, a transmission structure 640 and a driving motor 650. Among them, the feed hopper 610 communicates with the top of the oil storage tank 100. Two groups of pressure rollers 620 are arranged up and down relatively. Gears 630 that mesh with each other are coaxially arranged on the two groups of opposite pressure rollers 620. And each group of multiple pressure rollers 620 are sequentially connected through the transmission structure 640. The output end of the driving motor 650 is connected to one of the pressure rollers 620. In addition, through grooves 611 are respectively opened on both sides of the feed hopper 610. After the oil absorption cable 540 between the two second guide wheels 530 passes through one of the through grooves 611, it passes between the two groups of pressure rollers 620 and is led out from the other through groove 611. It should be noted that the oil absorption cable 540 passes between the pressure rollers 620. Through the extrusion between the pressure rollers 620, the oil in the oil absorption cable 540 can be squeezed out, so that the oil drips into the oil storage tank 100.

[0016] It is understandable that the squeezing action of the two groups of pressure rollers 620 can not only squeeze the oil suction rope 540, but also drive the oil suction rope 540 to move while the pressure rollers 620 rotate. If the oil suction rope 540 cannot move in actual use, the relevant staff can set a driving device 200 on the second guide wheel 530 to drive the second guide wheel 530, thereby ensuring the stability of the movement of the oil suction rope 540. Specifically, after the driving device 200 drives the entire device to move to the oil pollution position, the oil squeezing device 600 can be started by the controller, that is, the driving motor 650 drives the pressure rollers 620 connected thereto to rotate, so that the other pressure rollers 620 rotate synchronously. While the two sets of rollers 620 are rotating, the oil suction cable 540 is driven to move, so that the oil suction cable 540 can move slowly on the river surface, and absorb the oil on the river surface when the oil suction cable 540 moves slowly. After absorption, the oil suction cable 540 returns to between the two sets of rollers 620, squeezes out the oil, and drips into the oil storage tank 100. As the oil in the oil storage tank 100 increases, the draft of the oil storage tank 100 changes. At this time, the floating frame 510 always keeps floating and slides on the fixed rod 101, so that the oil suction cable 540 at the front end of the floating frame 510 can always keep the oil suction operation.

[0017] In one embodiment of the present invention, the solar panel 700 has a built-in energy storage unit, and supplies power to the oil detector 300, the visual recognition and positioning system 400, the data fusion processor and the oil squeezing device 600 respectively. It should be noted that the power storage function of the solar panel 700 can realize the power supply of the above-mentioned components to further improve the overall unmanned operation and stability. In addition, the device can replace the inspection personnel to conduct inspections, conduct reciprocating inspections at the shallows or edges along the river surface, or anchor at the shallows, and after an oil spill occurs, automatically drive to the oil spill location to perform oil recovery operations.

[0018] In summary, the river surface oil leakage detection and recovery device according to the embodiment of the present invention, by cooperating the oil pollution detector 300 and the visual recognition and positioning system 400, can more accurately identify the river surface oil leakage situation, improve the monitoring accuracy, and confirm the location of the oil pollution. When an oil leakage incident occurs, it can automatically navigate to the location of the oil pollution while notifying the inspection personnel, and recover the oil pollution at that location to avoid further spread of the oil pollution in the early stage of the oil leakage.
