Description

Technical Field

[0001] The utility model relates to the technical field of offshore detection and alarm in the petroleum and petrochemical industry, in particular to a novel oil spill detector. Background Art

[0002] With the frequent occurrence of oil spill accidents caused by human factors, material failure, sealing failure and other reasons in recent years, the treatment after the leak often requires multiple costs. Taking active preventive measures on production facilities can effectively reduce the occurrence of oil spills and mitigate their harm. Therefore, it is necessary and economically beneficial to attach importance to leak prevention and make advance investments. In addition to raising awareness and strengthening management, adopting more reliable designs and new materials to improve the mining, transportation, processing and sales of the oil industry, the construction of real-time and effective oil spill monitoring solutions, the use of highly sensitive oil spill detectors and oil spill monitoring systems can do a better job of early warning of oil spills and minimize the risk of oil spill accidents.

[0003] At present, the main detection methods include: mechanochemical method, image method, and spectroscopy. Among them, the mechanochemical method can only be used to detect whether there is an oil spill. The detection equipment or reagents need to be in direct contact with crude oil, which leads to the need for regular maintenance of the equipment, and the maintenance labor cost is high. At the same time, the trial scenario is a large-scale sea area detection, and chemical reagents may cause secondary pollution; the image method can only be used to detect whether there is an oil spill. This method is greatly affected by sunlight and external visibility, has a high false alarm rate, and is not accurate enough. The spectral method can achieve non-contact detection, is less affected by the external environment, and does not pollute the environment. It can not only detect whether there is an oil spill, but also measure the thickness of the oil film, thereby achieving accurate alarm in a small area of ​​sea with a low false alarm rate. At present, on-site staff prefer non-contact detection, which requires low requirements for the external environment when detection is required, and there is no pollution. It can achieve accurate alarm in a small area of ​​sea near the offshore platform, and the false alarm rate is low. Therefore, in response to the needs of most on-site staff at present, the spectral method is generally selected. The existing spectral method generally uses ultraviolet lamps as light sources, LED lamp beads as emission sources, and lasers as emission sources. Lasers have better unidirectionality and stronger anti-interference ability. However, according to spectral detection, due to the harsh environment on the sea surface, the existence of high corrosiveness and the influence of floating impurities, it is easy to cause corrosion or adhesion of floating impurities on the detection surface or camera surface, resulting in inaccurate test results. In severe cases, even false alarms may occur. Therefore, it is particularly important to keep the detection surface and camera surface clean. Utility Model Content

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a new type of oil spill detector, including an outer cover, a fill light, a camera, a detector movement, an outer shell and a detection head, the detection head is arranged in the outer cover, the outer shell includes a first shell and a second shell, the first shell and the second shell are welded together by a pipe clamp, and the interior of the first shell is connected to the interior of the second shell, the outer cover is threadedly connected to the second shell, the camera and the detector movement are respectively installed in the second shell, the fill light is installed in the first shell, and the detector movement is electrically connected to the fill light, the camera and the detection head respectively.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figure 1 and Figure 2As shown, the utility model is a novel oil spill detector, including an outer cover 1, a fill light 2, a camera 3, a detector core 4, a shell 5 and a detection head 9, wherein the detection head 9 is arranged in the outer cover 1, the shell 5 includes a first shell 6 and a second shell 7, the first shell 6 and the second shell 7 are welded together by a pipe hoop, and the interior of the first shell 6 and the interior of the second shell 7 are communicated, the outer cover 1 is threadedly connected with the second shell 7, the camera 3 and the detector core 4 are respectively installed in the second shell 7, the fill light 2 is installed in the first shell 6, and the detector core 4 is electrically connected with the fill light 2, the camera 3 and the detection head 9. In the description of the utility model, it should be understood that the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model. In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0026] The outer cover 1 is a cylindrical structure, and a transparent member 8 is provided at one end of the outer cover 1 connected to the second shell 7. The transparent member 8 can not only protect the structure inside the second shell 7, but also ensure that the camera 3 can shoot normally through the transparent member 8. In addition, the transparent member 8 is made of ultraviolet quartz glass, which has strong light transmittance to ultraviolet wavelengths, so the ultraviolet light transmittance is high.

[0027] A waterproof sealing ring is installed at the position where the outer cover 1 is connected to the second shell 7 for sealing, which can effectively prevent rainwater and impurities from entering the outer cover 1 or the interior of the second shell 7. When the detector is actually installed, the opening of the outer cover 1 away from the second shell 7 is set downward, that is, the opening of the outer cover 1 is set toward the sea surface. Therefore, the outer cover 1 can not only effectively prevent rain and impurities, but also block the wind and rain on the side, prevent debris and rain from sticking to the detection head 9 and the transparent part 8, so as to protect the detection head 9 and the transparent part 8 from being clean, thereby ensuring the monitoring accuracy and reducing the false alarm rate. At the same time, it can also effectively ensure the clarity of the pictures or videos taken by the camera 3. In addition, the outer cover can also block part of the external ambient light to reduce the interference of external ambient light.

[0028] The detector core 4 is used to supply power to the fill light 2 and the camera 3, and the detector core 4 can control the camera 3 and the detection head 9 to work; the detector core 4 is connected to the control equipment of the central control room of the offshore platform through a cable, and the staff can perform various settings and operations on the detector core through the control equipment. The central control room and the control equipment of the offshore platform are respectively the prior art. In the actual working process, the staff can set the camera 3 to two working modes, one is a 24-hour continuous working mode, and the other is that when the detector core 4 detects the oil spill, an alarm signal is issued, and the camera 3 starts to record the video throughout the process. In general, the camera 3 is set to record the video 24 hours a day. When the detector is started, the camera 3 will work all the time after the detector core 4 starts working, that is, the camera 3 monitors the scene in real time, so that the subsequent staff can retrieve the video of the scene at that time. The detector described in the utility model can record the scene in real time when an oil spill occurs. The detector core 4 is sturdy and durable, and the detector core 4 has a built-in hard disk. While serving as a data server, it can also store pictures or videos; the detector core 4 has a built-in hardware encryption dog, and the data and software are safer.

[0029] The detection head 9 can emit laser, and the detector core 4 can analyze and calculate the fluorescence intensity generated by laser excitation with oil film coverage and the Raman signal intensity of water without oil film coverage, and can obtain the oil film thickness at different distances, and the oil film thickness measurement range is wide. When oil spill is detected, the detector core 4 can send out an alarm signal, and the alarm signal is transmitted to the central control room, and the staff conducts investigation according to the position displayed on the display of the control device.

[0030] The fill light 2 is provided with a photosensitive sensor, which can autonomously sense the external light intensity to decide whether to fill light. Specifically, the photosensitive sensor can detect the external light intensity in real time and convert it into a specific value to compare with the set threshold. The value is low when the light intensity is low, and the value is high when the light intensity is high. When the value is lower than the preset threshold, it is determined that the external light intensity is low, and the fill light 2 is turned on to supplement the light intensity. When the value is higher than the preset threshold, it is determined that the external light intensity is high, and the fill light 2 is turned off. The existence of the fill light 2 can ensure that the camera 3 can also get fill light when the light is weak, so that the camera 3 can shoot clearer.

[0031] The shell 5 has an explosion-proof rating of Ex db IIC T6 and a protection level of IP66 / IP68, and is used to protect the internal electrical mechanism; the outer cover 1 has an explosion-proof rating of Ex db IIC T6 and a protection level of IP66 / IP68, and is used to protect the detection head 9 and the transparent part 8. The outer cover 1 and the shell 5 cooperate with each other to ensure that the protection level of the entire detector can reach IP66 / IP68, ensure that the internal components can operate safely, and enable the entire device to be suitable for harsh marine environments.

[0032] A handle 10, a connecting portion 11 and a mounting plate 12 are installed on the second shell 7; the handle 10 makes it convenient for the staff to carry the detector, the connecting portion 11 is used to screw the cable connector into the cable, and the mounting plate 12 is provided with a mounting hole, through which the detector can be installed and fixed in a suitable position.

[0033] In actual work, the detector described in the utility model is first installed and fixed at the position of the offshore platform where oil spill needs to be monitored through the mounting plate 12, and then the detector is started to work, and the camera 3 is also turned on for 24-hour recording. The detection head 9 can continuously emit laser light to the water surface. When the laser light is incident on the water surface, a series of optical phenomena such as reflection, refraction, absorption, and scattering will occur in the water, and the excitation of organic molecules in the water can also produce fluorescence emission. The detector movement 4 analyzes and calculates the fluorescence intensity generated by laser excitation covered with oil film and the Raman signal intensity of water without oil film coverage, and can obtain the thickness of the oil film at different distances, and the measurement range of the oil film thickness is wide. When oil spill occurs, the detector movement 4 will alarm. The detector has a built-in camera 3, which can monitor and record around the clock. When oil spill occurs, it can take photos and record on the spot. The staff can retrieve the video of the oil spill site in the central control room of the offshore platform.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
