The examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] The following will describe the specific implementation of the present invention in detail with reference to specific embodiments.

[0029] In one embodiment, please refer to Figure 1 and Figure 2 , a settlement and tilt monitoring device for an offshore oil platform is provided, including a monitoring main frame 11 and a plurality of tilt monitoring supports 12 mounted on the monitoring main frame 11; a tilt monitoring component 13 is arranged at the bottom of the tilt monitoring support 12, and a plurality of support frames 14 are further arranged on the monitoring main frame 11. The support frames 14 are located at the side edges of the corresponding tilt monitoring supports 12. A settlement monitoring support 15 is mounted on the support frames 14. A hoisting support frame 16 is installed at the bottom of the settlement monitoring support 15, and a settlement monitoring component 17 is installed on the hoisting support frame 16.

[0030] A positioning support frame 21 is arranged inside the inclination monitoring support 12. The inclination monitoring assembly 13 includes a fixed base 23 mounted on the positioning support frame 21, a lifting device 24 arranged on the fixed base 23, and a level detector 25 installed at the end of the lifting device 24.

[0031] A main frame support bar 22 is arranged on the side edge of the inclination monitoring support 12. The positioning support frame 21 is fixed on the main frame support bar 22. A support base 31 is also arranged on the monitoring main frame 11. The support frame 14 is supported at the frame end of the support base 31. The settlement monitoring assembly 17 includes an adjustment assembly 32 and a light-sensing sensing detection piece 33 for supporting the adjustment assembly 32. The light-sensing sensing detection piece 33 is swingably installed on the hoisting support frame 16.

[0032] This embodiment is arranged on the periphery of an offshore oil platform. The monitoring main frame 11 can be respectively arranged at each side edge of the offshore oil platform. The monitoring main frame 11 is welded by high-strength steel to ensure its stable structure and corrosion resistance to adapt to the harsh conditions of the marine environment. The monitoring main frame 11 is designed as a multi-layer structure to facilitate the installation and maintenance of each monitoring assembly. A number of inclination monitoring supports 12 are evenly distributed and fixed on the monitoring main frame 11. These supports are also made of corrosion-resistant materials and are connected to the main frame by bolts or welding to ensure that they will not loosen during long-term use; an inclination monitoring assembly 13 is equipped at the bottom of each inclination monitoring support 12. This assembly is connected to the data processing system inside the monitoring main frame 11 by cable or wireless means.

[0033] The inclination monitoring assembly 13 includes a fixed base 23 mounted on the positioning support frame 21. The fixed base 23 adopts a stable structural design to ensure that it can firmly support the subsequent lifting device 24 and level detector 25. The fixed base 23 and the positioning support frame 21 are connected by a precise assembly process to ensure the stability of their relative positions.

[0034] The lifting device 24 is arranged on the fixed base 23. It is responsible for driving the level detector 25 to move up and down. The lifting device 24 adopts a high-precision transmission mechanism to ensure the stability and accuracy of the level detector 25 during movement. The level detector 25 is a key component of the monitoring device. It is responsible for real-time monitoring of the inclination of the offshore oil platform. The level detector 25 adopts the implementation method of static level monitoring, that is, using the principle of the horizontal plane of liquid in a static state to measure the inclination of the platform. A precise sensor and a data processing unit are arranged inside the level detector 25, which can convert the monitored data into digital signals in real time and send them to the monitoring center by wireless transmission.

[0035] The settlement monitoring component 17 is responsible for monitoring the settlement of the offshore oil platform in real time. This component includes an adjustment component 32 and a light-sensing detection component 33. The adjustment component 32 can be finely adjusted according to the monitoring requirements to ensure that the light-sensing detection component 33 always maintains the best working state; the light-sensing detection component 33 adopts fiber Bragg grating sensing technology, which has the advantages of high precision, high sensitivity, and strong anti-interference ability. It is swing-mounted on the hoisting support frame 16 to capture the settlement information of the platform in real time. The grating structure inside the fiber Bragg grating sensor can sense external physical changes (such as strain, temperature, etc.) and convert them into changes in optical signals. These optical signals are then converted into electrical signals and analyzed and calculated by the data processing unit to finally obtain the settlement data of the platform.

[0036] In this embodiment, by adopting the lifting component 24, the level detector 25, and the high-precision light-sensing detection component 33, high-precision real-time monitoring of the settlement and inclination of the offshore oil platform can be achieved, providing reliable data support for the safe operation of the platform. Both the inclination monitoring component and the settlement monitoring component are designed with flexible adjustment mechanisms, which can adapt to different marine environments and platform structural characteristics to ensure the accuracy and reliability of the monitoring results.

[0037] In one embodiment, please refer to Figures 2 to 5 , this embodiment is a further optimization of the above embodiment. On this basis, for the specific implementation structure of the adjustment component 32, this embodiment is designed as follows:

[0038] The hoisting support frame 16 includes a vertical support frame 41 and a horizontal support frame 43 installed on the settlement monitoring support 15. A connection strengthening frame 42 is arranged between the vertical support frame 41 and the horizontal support frame 43, and a numerical control detection box 44 is also installed on the connection strengthening frame 42. The vertical support frame 41 and the horizontal support frame 43 are composed of them, and they are installed on the settlement monitoring support 15 by welding or bolt connection to ensure the stability and reliability of the structure. A connection strengthening frame 42 is added between the vertical support frame 41 and the horizontal support frame 43 to further enhance the strength and rigidity of the overall structure. The numerical control detection box 44 is fixedly installed on the connection strengthening frame 42 by bolts and is used to receive and process data from the sensors.

[0039] The adjusting assembly 32 includes an adjusting base plate 51. The light-sensing detection component 33 includes a supporting base member 52 mounted on the adjusting base plate 51 and a detection base frame 53 fixed to the supporting base member 52. A hoisting support bolt 61 is provided on the transverse support frame 43, and a swinging bolt 63 is mounted on the hoisting support bolt 61. One end of the adjusting base plate 51 is provided with a steering adjusting roller 62, and the steering adjusting roller 62 is mounted on the swinging bolt 63. An arc-shaped track 64 is provided on the vertical support frame 41, and the other end of the adjusting base plate 51 is provided with a steering sliding block 65, and the steering sliding block 65 is slidably mounted along the arc-shaped track 64. The adjusting assembly 32 further includes a side wing frame 71 mounted on the adjusting base plate 51 and a sliding rod 72 provided on the side edge of the side wing frame 71. The supporting base member 52 is slidably mounted on the sliding rod 72. Transmission wheels 73 are provided at both ends of the frame of the adjusting base plate 51, and a transmission chain belt 74 is provided between the transmission wheels 73. A fixing bolt 75 is mounted on the top of the supporting base member 52, and the fixing bolt 75 is fixedly mounted on the transmission chain belt 74.

[0040] The adjusting base plate 51, as the core component, is installed at an appropriate position on the transverse support frame 43 by welding or fasteners. The assembly of the light-sensing detection component 33 involves firmly mounting the supporting base member 52 on the adjusting base plate 51, and then fixing the detection base frame 53 to the supporting base member 52 for capturing minute changes in the settlement of the platform.

[0041] To achieve flexible adjustment of the light-sensing detection component 33, a hoisting support bolt 61 is installed on the transverse support frame 43, and the swinging bolt 63 passes through the hoisting support bolt 61, allowing the steering adjusting roller 62 to swing within a certain range. An arc-shaped track 64 is provided on the vertical support frame 41, and the other end of the adjusting base plate 51 is provided with a steering sliding block 65, enabling the adjusting base plate 51 to slide smoothly along the arc-shaped track 64 to achieve fine adjustment in the horizontal and vertical directions.

[0042] The installation of the side wing frame 71 enhances the lateral stability of the adjusting base plate 51, and the sliding rod 72 provided thereon allows the supporting base member 52 to be finely adjusted in the horizontal direction. The combined use of the transmission wheels 73 and the transmission chain belt 74 can synchronously move the supporting base member 52 through electric control drive. The fixing bolt 75 locks the supporting base member 52 at a specific position on the transmission chain belt 74 to ensure stability after adjustment. This design allows us to adjust the position of the light-sensing detection component 33 according to actual needs to adapt to different monitoring requirements. This embodiment enables the light-sensing detection component 33 to be precisely adjusted to the optimal monitoring position, improving the accuracy of settlement and settlement monitoring of the offshore oil platform.

[0043] In one embodiment, please refer to Figure 5 and Figure 6, as a further optimization of the above embodiment, on this basis, for the specific implementation structure of the detection base frame 53, this embodiment is designed as follows:

[0044] Light-sensitive machine barrels 81 are installed at the four corner positions of the detection base frame 53. A detection head 82 is provided at the bottom of the light-sensitive machine barrel 81. A light-sensitive receiving end 83 is installed on the detection head 82, and a light-sensitive transmission end 84 is provided at the detection end of the light-sensitive receiving end 83.

[0045] The detection base frame 53 is the basic structure for installing the light-sensitive machine barrels 81. It is usually designed as a strong and stable frame that can withstand various harsh conditions in the marine environment. The four corner positions of the detection base frame 53 are precisely calculated and four light-sensitive machine barrels 81 are installed to ensure all-round and multi-angle monitoring. The light-sensitive machine barrel 81 is a sealed and waterproof container with precision optical elements and fiber Bragg grating sensors installed inside. Its bottom is designed with a detection head 82, which is the part in direct contact with the platform surface and is used to receive and reflect light. A light-sensitive receiving end 83 is installed on the detection head 82. This is a highly sensitive optoelectronic converter that can convert the received optical signal into an electrical signal for processing. A light-sensitive transmission end 84 is provided at the detection end of the light-sensitive receiving end 83. This is a specially designed fiber optic interface for connecting to the fiber Bragg grating sensor. The fiber Bragg grating sensor is a sensing element based on fiber optic technology that uses the reflection and transmission characteristics of the grating structure in the optical fiber to monitor. When the platform settles, the contact state between the detection head 82 and the platform surface will change, resulting in changes in the wavelength or intensity of the reflected light. These changes are transmitted to the fiber Bragg grating sensor through the light-sensitive transmission end 84. After signal processing and analysis, the settlement data of the platform can be obtained.

[0046] In one embodiment, please refer to Figure 7 and Figure 8 , as a further optimization of the above embodiment, on this basis, for the specific implementation structure of the elevator member 24 and the level detector 25, this embodiment is designed as follows:

[0047] The fixed base 23 includes a lifting base 92 and a mounting frame 91 provided on the lifting base 92. The mounting frame 91 is fixed to the main frame support bar 22. A fixed bottom frame 93 is provided inside the mounting frame 91, and the fixed bottom frame 93 is installed on the positioning support frame 21; the elevator member 24 includes a lifting module 94 and a lifting slide rail 96 provided on the lifting module 94. An outer card limit seat 95 is provided inside the lifting base 92, and the lifting slide rail 96 is limited and embedded in the outer card limit seat 95; a fixed clip 97 is provided on the outer shell of the lifting base 92, and the fixed clip 97 locks and fixes the lifting module 94.

[0048] The level detector 25 is installed at the bottom end of the elevator component 24. The lifting module 94 adopts a combination of a high-precision motor and a reducer to achieve the smooth lifting of the lifting slide rail 96, ensuring that even the slightest adjustment of the level detector 25 in the vertical direction can be accurately controlled. A position sensor can also be installed inside the lifting module 94, which can monitor the current position of the lifting slide rail 96 in real time and feedback the position information to the control system. The control system makes fine adjustments based on the feedback information to ensure that the level detector 25 reaches the predetermined installation height. The fixed clip 97 uses an electric braking method, which can be electrically braked and unlocked. When it is necessary to adjust the position of the level detector 25, the braking component on the fixed clip 97 can be loosened to unlock the lifting module 94. After unlocking, the lifting module 94 can be driven by the control system to perform lifting adjustments.

[0049] The level detector 25 includes a fixed base plate 101 installed at the bottom end of the elevator component 24 and a static level meter 102 installed on the fixed base plate 101. A connecting branch pipe 105 is externally connected to the static level meter 102, and a water level detection support cylinder 106 is installed on the connecting branch pipe 105; a stress transmitter 103 is arranged at the bottom of the static level meter 102, and a plumb bob bolt 104 is installed on the stress transmitter 103.

[0050] The static level meter 102 is a high-precision measuring instrument based on the principle of hydrostatic pressure. The inside of the static level meter 102 is filled with a high-viscosity measuring liquid, and a stress transmitter 103 is arranged at the bottom of the static level meter 102. The stress transmitter 103 can effectively transmit the stress changes generated when the platform settles or tilts to the static level meter 102, enabling it to more accurately measure the tilt angle of the platform. At the same time, in order to calibrate and verify the measurement results of the static level meter 102, a plumb bob bolt 104 is installed on the stress transmitter 103. The plumb bob bolt 104 can provide a stable vertical reference direction. By comparing with the measurement results of the static level meter 102, the accuracy of its measurement can be verified.

[0051] The static level meter 102 is also externally connected to a connecting branch pipe 105 and a water level detection support cylinder 106. The connecting branch pipe 105 connects the measuring liquid inside the static level meter 102 with the water level detection support cylinder 106. When the platform undergoes tilt changes, the liquid level and pressure inside the static level meter 102 change, and the liquid level in the water level detection support cylinder 106 will also rise or fall accordingly. By monitoring the change of the liquid level in the water level detection support cylinder 106, we can obtain the tilt information of the platform in real time and transmit it to the monitoring center for further analysis and processing.
