Description

Technical Field

[0001] The utility model relates to a settlement and tilt monitoring device, in particular to a settlement and tilt monitoring device for an offshore oil platform, belonging to the technical field of offshore oil platform monitoring. Background Art

[0002] Offshore oil platforms are facilities used for offshore oil and gas exploration, development, and production. They are typically designed as floating or fixed structures, supporting drilling equipment, production facilities, and living quarters. Depending on water depth, sea conditions, and reservoir depth, offshore oil platforms can come in a variety of types, including fixed platforms, floating production storage and offloading vessels (FPSOs), jack-up platforms, and semi-submersible platforms.

[0003] Patent No. CN216482979U discloses a device for monitoring the subsidence and inclination of an offshore oil platform. The device includes a static leveling device installed on the offshore oil platform to measure the vertical displacement of the offshore oil platform; a strain gauge installed on a crane or target device on the offshore oil platform to measure the structural deformation of the target structure; a fiber grating demodulator connecting the static leveling sensor and the strain gauge via an optical cable to convert optical signals into electrical signals for transmitting measurement data; and a data processor in communication with the fiber grating demodulator to receive and analyze the transmitted data. This device primarily utilizes a large number of sensors to collect structural deformation data from the platform and processes it to obtain analysis results, saving significant labor and providing reliable support for production and life on the offshore oil platform.

[0004] However, in order to achieve the effect of settlement and tilt monitoring, it is necessary to install a large number of sensors at different locations on the offshore oil platform, which not only leads to excessively high monitoring costs, but also the use of only static level sensors cannot effectively monitor the vertical settlement of offshore oil platforms. The working principle of the static level sensor is based on the connecting pipe principle, that is, after the liquid is injected into the U-shaped tube with openings at both ends, the liquid will remain at the same horizontal plane under the action of atmospheric pressure and gravity; by measuring the changes in the liquid level, settlement monitoring is achieved. However, in the ocean, the sea level is changing. During the monitoring process, it is impossible to separate the offshore platform as a whole and determine an observation point whose position will not change. Especially in deep sea areas, when the offshore platform as a whole vertically settles, it cannot be effectively monitored. For this reason, a offshore oil platform settlement and tilt monitoring device is proposed. Utility Model Content

[0040] The monitoring mechanism 3 includes a storage box 301, a traction rope 302, a counterweight cone 303 and two sonar sensors 304;

The cover 54 is fixed to the housing 102 by bolts so that the adjusting knob 204 can be limited by the cover 54 to prevent the reel 201 from rotating during the monitoring process.

[0046] In one embodiment, the monitoring mechanism 3 further includes a central controller 305 , a communication module 306 , and a gyro sensor 307 ;

[0049] In one embodiment, the photovoltaic mechanism 4 includes a support frame 401, a photovoltaic frame 402, a photovoltaic cell 403, two connecting frames 404 and two fastening knobs 405;

[0050] Among them, the support frame 401 is fixedly connected to the top of the slide 103, the photovoltaic frame 402 is hinged to one side of the upper surface of the support frame 401, the photovoltaic cell 403 is installed on the upper surface of the photovoltaic frame 402, one end of the two connecting frames 404 are hinged to the bottom of the photovoltaic frame 402, and the other ends of the two connecting frames 404 are hinged to one side of the support frame 401.

The middle of the upper surface of the housing 102 is connected to the input wire 51, and the bottom of the photovoltaic cell 403 is connected to the output wire 52. A waterproof connector 53 is connected between the input wire 51 and the output wire 52;

[0051] By moving the photovoltaic frame 402, the photovoltaic cell 403 and the connecting frame 404 are driven to move so that the angle of the photovoltaic cell 403 can be adjusted according to actual needs, and then the node of the connecting frame 404 is fixed by turning the fastening knob 405, so that the fixed connecting frame 404 can be used to support the support frame 401 and the photovoltaic frame 402.

[0052] In one embodiment, two T-shaped slide rails 57 are symmetrically provided on the inner side wall of the engaging frame 101, and two slide grooves 58 are symmetrically provided on one side of the housing 102. The outer side wall of the T-shaped slide rail 57 is slidably connected to the inner side wall of the slide groove 58.

[0053] The T-shaped slide rail 57 and the slide groove 58 are provided to position the engaging frame 101 and the housing 102 .

[0054] In one embodiment, a winding groove 59 is provided on the top of the outer wall of the storage box 301;

[0055] The winding groove 59 is used to provide a winding space for the traction rope 302, so that the storage box 301 and the counterweight cone 303 are closer for storage.

[0056] When the present invention is in operation, the clamping frame 101 is integrally mounted and fixed on the offshore oil platform by utilizing the fixing ears 56 , so that the housing 102 , the slide frame 103 and other structures can be assembled later.

[0057] When the housing 102 needs to be assembled as a whole, first, the reel 201 is rotated by turning the adjusting knob 204 so that the flexible communication line 203 can be released by the rotating reel 201, and then the length of the released flexible communication line 203 is adjusted according to actual needs to ensure that the storage box 301 can be immersed in the sea water as a whole. When the adjustment is completed, the cover plate 54 is covered on one side of the housing 102 by moving the rod, and the adjustment knob 204 passes through the inner side of the cover plate 54. Then, the cover plate 54 is fixed to the housing 102 with bolts so that the adjustment knob 204 can be adjusted by the cover plate 54. The button 204 is used to limit the position to prevent the winding wheel 201 from rotating during the monitoring process. The set collector ring 202 is used to connect the power between the flexible communication line 203 and the central controller 305 to ensure that the central controller 305 and the flexible communication line 203 are always in a connected state during the rotation of the winding wheel 201; then the housing 102 is moved as a whole and slid into the interior of the snap-fit frame 101 to complete the assembly operation between the housing 102 and the snap-fit frame 101, and the set T-shaped slide rail 57 and slide groove 58 are used to position the snap-fit frame 101 and the housing 102.

[0058] When the slide 103 needs to be assembled, it is only necessary to slide the slide 103 into the outside of the snap-fit frame 101 by moving it, and then squeeze the snap-fit frame 101 with the thread by turning the locking knob 55 to fix the slide 103 and the snap-fit frame 101, and then connect the input wire 51 and the output wire 52 by using the waterproof connector 53, so that the photovoltaic cell 403 can be used to power the entire device, and the entire device can also be connected separately according to actual needs. After the input wire 51 and the output wire 52 are connected, the photovoltaic cell 403 and the connecting frame 404 are driven to move by moving the photovoltaic frame 402, so that the angle of the photovoltaic cell 403 can be adjusted according to actual needs, and then the node of the connecting frame 404 is fixed by turning the tightening knob 405, so that the fixed connecting frame 404 can be used to support the support frame 401 and the photovoltaic frame 402.

[0059] After the storage box 301 is put into the seawater, the counterweight cone 303 uses the traction rope 302 to provide a continuous downward pulling force to the storage box 301 as a whole under the action of gravity, so as to ensure that the sonar sensor 304 can face the seabed directly.

[0060] When monitoring is being carried out, a sound wave signal is emitted by the sonar sensor 304. When the sound wave signal encounters an object or the seabed, it is reflected. Then, the distance between the sonar sensor 304 and the seabed is calculated based on the reflection time and waveform, so that the central controller 305 can judge whether the offshore oil platform as a whole has vertically sunk based on the change in distance data. When the amplitude of the distance data change reaches a threshold, the central controller 305 uses the communication module 306 to send an early warning message to the control terminal; at the same time, the posture data of the current casing 102, the locking frame 101 and the offshore oil platform as a whole are detected by the set gyroscope sensor 307, so that the central controller 305 can judge whether the offshore oil platform as a whole has tilted based on the change in posture data. When the amplitude of the posture data change reaches a threshold, the central controller 305 uses the communication module 306 to send an early warning message to the control terminal.

[0061] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in this utility model, and such modifications or substitutions are intended to fall within the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model shall be based on the scope of protection of the claims.
