Description

Technical Field

[0001] The present invention relates to the technical field of oil spill monitoring, and particularly to an oil spill monitoring device for an offshore platform. Background Art

[0002] Currently, the traditional detection methods for oil spills on the sea surface are aerial remote sensing and satellite remote sensing. However, both of them have different problems. Aerial remote sensing monitoring is not real-time, and satellite remote sensing has inaccuracies for small-scale pollution. Therefore, researching and designing a system that can monitor floating oil spills on the sea surface in real time and accurately is of great significance for protecting marine environmental resources. In view of the advantages of near-infrared spectroscopy analysis technology, such as fast speed, low cost, pollution-free, and non-destructive to samples, as well as its successful application in the identification of pure oils, an oil spill detection system based on near-infrared spectral absorption technology is designed. This system uses near-infrared light as the detection light source and combines a data acquisition module mainly based on a single-chip microcomputer to conduct on-line real-time monitoring of the offshore sea surface, which is of great significance for protecting the environmental safety of offshore waters. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose an oil spill monitoring device for an offshore platform.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] Design an oil spill monitoring device for an offshore platform, including a monitoring rod. A plurality of control boxes are arranged in the monitoring rod. The monitoring rod is fixedly connected to the offshore platform by bolts. A column is vertically arranged at the bottom of the offshore platform. The monitoring rod extends into the sea water. Signal lines are connected between the plurality of control boxes. Detection devices are installed on the signal lines. A towing rope is connected to the plurality of control boxes. The towing rope passes through the monitoring rod and extends to the offshore platform.

[0006] The control box includes an ultraviolet module, a micro-capacitance scanning module, a camera module, a photomultiplier module, a power module, and a control module. The output end of the power module is electrically connected to the input end of the control module through a wire. The output end of the ultraviolet module is connected to the input end of the photomultiplier module through a wire. The output end of the photomultiplier module is electrically connected to the input end of the conditioning circuit module. The output end of the conditioning circuit module is connected to the input end of the differential circuit module. The output end of the differential circuit module is electrically connected to the input end of the A / D circuit module through a wire. The output end of the A / D circuit module is connected to the input end of the control module through a signal line. The output end of the camera module is connected to the input end of the image processing module. The output end of the image processing module is connected to the input end of the control module through a signal line. The output end of the micro-capacitance scanning module is connected to the input end of the amplification module through a signal line. The output end of the amplification module is connected to the input end of the A / D circuit module through a signal line. The output end of the control module is electrically connected to the input end of the data center module through a signal line. The output end of the data center module is connected to the input end of the wireless module through a signal line.

[0011] Preferably, roller brackets are provided at both the top and the bottom of the control box. Guide wheels are installed on the roller brackets, and guide rails slidably connected to the guide wheels are provided on the inner wall of the monitoring rod.

[0012] An oil spill monitoring device for an offshore platform proposed by the present invention has the following beneficial effects: By setting a micro-capacitance scanning module, which is arranged in the monitoring rod, multiple detection capacitors are formed between the detection electrodes and the inner wall of the monitoring rod. Due to the large differences in the dielectric constants of oil, water, and seawater, the micro-capacitance scanning module can monitor whether there is an oil spill on the sea surface around the offshore platform. At the same time, an ultraviolet module is set up to irradiate the sea surface. Since the reflection conditions of seawater and oil for ultraviolet light are different, it can be detected whether there is a leak after receiving the ultraviolet light reflected by the sea surface. The set camera module directly takes pictures of the sea surface around the offshore platform, and then transmits the captured image information to the intelligent terminal through the wireless module to remind the staff whether there is an oil spill. Compared with the existing control box, the sea surface around the offshore platform is monitored by multiple methods such as the ultraviolet module, the micro-capacitance scanning module, and the camera module at the same time, which has the advantage of high monitoring accuracy.
