[0002] With the continuous development of industrial modernization, a large number of offshore oil extraction projects have increased the risk of offshore oil spill accidents.

[0003] Oil booms are important equipment for intercepting and controlling oil spills and preventing them from spreading further with the water flow. The level of containment is directly related to the quality of oil spill accident handling. In the actual oil spill containment process, affected by factors such as the wind and wave velocity at sea and the towing speed of the ship, the oil boom is prone to flipping, resulting in oil layer loss and containment failure. In oil spill containment operations, oil booms usually need to be deployed over a long distance of hundreds of meters or even thousands of meters. Once the oil boom flips and fails, on-site personnel often need to wait for a period of time before discovering the oil spill. After the oil boom flips and fails, it is necessary to dispatch staff to find and deal with the failed location, and to re-contain the leaked oil. Therefore, it will not only lead to further spread of the oil spill, but also continue to consume the energy of emergency personnel, which is time-consuming and labor-intensive. Summary of the invention

[0006] Furthermore, the digital control module calculates an average value of the oil boom flip angle within a time period of 1 to 1000 seconds.

[0007] Furthermore, the calculation formula of the average value of the inclination angle is as follows:

[0008]

[0009] in, is the average tilt angle, y is the measured tilt angle, a is the starting time of a time period, and b is the ending time of a time period.

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0032] like Figure 1 , Figure 2 As shown, an oil boom rollover detection and warning device includes a housing 8, in which a digital control module 1, an inclination angle detection module 2, a positioning module 3, a signal transmission module 4, a light warning module 5 and a power supply module 6 are arranged. Figure 3As shown, the shell 8 is installed on the joint of the oil boom 9, at the junction of the float and the skirt. The shell 8 is treated with corrosion protection and its sealing is guaranteed to prevent seawater corrosion and infiltration. The tilt angle detection module 2 detects the flip angle of the oil boom 9 in real time, the positioning module 3 locates the position of the device in real time, and the digital control module 1 calculates the average flip angle of the oil boom 9 within a time period. The tilt angle detection module 2 and the positioning module 3 are respectively connected to the input end of the digital control module 1. The output end of the digital control module 1 is respectively connected to the signal transmission module 4 and the light warning module 5, and the signal transmission module 4 transmits the data generated by the digital control module 1 and the positioning module 3 to the user end. The light beam emitted by the light warning module 5 swings with the flip angle of the oil boom 9. The digital control module 1, the tilt angle detection module 2, the positioning module 3, the signal transmission module 4 and the light warning module 5 are respectively connected to the power supply module 6, and the power supply module 6 supplies power to the digital control module 1, the tilt angle detection module 2, the positioning module 3, the signal transmission module 4 and the light warning module 5.

[0033] The digital control module 1 is a microcontroller unit (MCU), also known as a single chip microcomputer (Single Chip Microcomputer) or a single chip microcomputer, which is connected to the tilt angle detection module 2, the positioning module 3, the signal transmission module 4, and the light warning module 5 to coordinate and control each module, and calculate the average value and gear position of the angle data measured by the tilt angle detection module 2.

[0034] In order to avoid misjudgment due to the short-term tipping of the oil boom 9, the digital control module 1 of this embodiment calculates the average value of the flip angle of the oil boom 9 within a time period of 1 to 1000 seconds. Preferably, the calculation formula of the average value of the tilt angle is as follows:

[0035]

[0036] in, is the average tilt angle, y is the measured tilt angle, a is the starting time of a time period, and b is the ending time of a time period.

[0037] The present invention is divided into 3 to 18 gears according to the average value. Specifically, in this embodiment, the verticality of the skirt of the oil boom 9 is taken as the reference, the inclination angle of 0° to ±10° is gear I, the inclination angle of ±10° to ±20° is gear II, the inclination angle of ±20° to ±30° is gear III, and the inclination angle of ±30° to ±45° is gear IV.

[0038] The tilt angle detection module 2 is used to detect the flip angle of the oil boom 9 in real time. Specifically, the tilt angle detection module 2 provided in this embodiment is a biaxial or triaxial acceleration sensor. The measurement range of the tilt angle detection module 2 is ±60°.

[0039] The positioning module 3 is used to locate the location of the device in real time and synchronize the location information to the signal transmission module 4 .

[0040] The signal transmission module 4 is used to transmit the data generated by the digital control module 1 and the positioning module 3 to the user end. Preferably, the signal transmission module 4 provided in this embodiment is one or more wireless transmission communication modes of ZigBee, LoRa or 433MHz.

[0041] The light beam emitted by the light warning module 5 swings with the turning angle of the oil boom 9, thereby instantly amplifying the angle information of the turning of the oil boom 9, making it more convenient for on-site personnel to observe at night. Specifically, the light warning module 5 provided in this embodiment uses lamps with obvious light beams such as LED spotlights and laser lights to irradiate upward, and the light beam can swing with the turning of the oil boom 9, which can better achieve the effect of amplifying the turning information of the boom.

[0042] Preferably, the color of the light beam emitted by the light warning module 5 changes color according to the gear position to show the flipping trend. The swinging color change of the light beam simultaneously realizes the instant amplification of the flipping angle information and the stable display of the flipping trend information. Specifically, this embodiment uses C++ language programming to make the color of the light beam emitted by the light warning module 5 change color according to the gear position, and the colors of gears I to IV are red, orange, yellow, and green respectively.

[0043] The power supply module 6 is connected to the digital control module 1, the tilt angle detection module 2, the positioning module 3, the signal transmission module 4, and the light warning module 5 to provide power to each module. Preferably, the power supply module 6 provided in this embodiment is connected to the solar panel 7. During use, the upper solar panel can be used to supplement the battery power, thereby ensuring the normal use of the device at night. When in use, the device can be fixed at the junction of the float and the skirt of the oil boom 9 joint.

[0044] When using, Figure 4 , Figure 5 As shown, after the device of the present invention is installed on the oil boom 9, it emits an upward light beam parallel to the oil boom 9 body. As the oil boom 9 tilts, the light beam also changes color and swings, thereby amplifying the tilt information of the oil boom 9 and clearly and prominently showing the flipping of the oil boom 9.

[0045] The working principle of the present invention is as follows:

[0046] The tilt angle detection module 2 and the positioning module 3 monitor the tilt angle and position information of the oil boom 9 respectively, and transmit the data to the digital control module 1. The digital control module 1 calculates the tilt angle data to obtain the average angle of the oil boom 9 flipping within the time period, divides the average value into grades according to the angle size, and transmits the graded result to the light warning module 5 and the signal transmission module 4. After receiving the gear data, the light warning module 5 always lights up different colors for display according to the graded result. The light changes color and swings with the tilt of the oil boom 9, so that the on-site personnel can quickly judge the approximate posture of the oil boom 9 and determine the flipping position at night. At the same time, the signal transmission module 4 wirelessly transmits the received gear information and positioning information to the user end, and displays the installation position, detection status and flipping warning of each device on the user end, so as to uniformly monitor the oil boom 9 over a large range and long distance. The power supply module 6 provides power for the entire system, and can charge the battery through the solar panel 7 during the day to ensure the long-term use of the device.
