Description

Technical Field

[0001] This utility model relates to the field of drilling platform early warning technology, and in particular to a drilling platform auxiliary positioning early warning device. Background Technology

[0002] Offshore drilling platforms are primarily used as offshore structures for drilling wells. They are equipped with drilling, power, communication, and navigation equipment, as well as safety, rescue, and personnel living facilities. They are an indispensable tool for offshore oil and gas exploration and development, and mainly include jack-up and semi-submersible drilling platforms.

[0003] In offshore drilling platform operations, platform stability and safety are of paramount importance. Due to the complex and ever-changing marine environment, drilling platforms may be affected by natural factors such as wind, waves, ocean currents, and tides, leading to platform displacement or flooding accidents. Traditional monitoring methods mainly rely on manual inspections or simple sensor alarms, which suffer from problems such as delayed response and insufficient accuracy. For example, existing flood detection devices usually use a single water level sensor, which is easily affected by seawater fluctuations, leading to false alarms or missed alarms. Platform positioning mostly relies on manual observation or periodic GPS data recording, which cannot monitor position changes in real time and provide timely warnings. In addition, existing systems often lack remote data transmission capabilities, making it difficult to transmit early warning information to the control center in a timely manner, affecting emergency response efficiency.

[0004] Therefore, it is necessary to provide a new drilling platform auxiliary positioning and early warning device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary positioning and early warning device for drilling platforms.

[0006] The drilling platform auxiliary positioning and early warning device provided by this utility model includes: a rectangular frame, a water flooding detection mechanism, a GPS positioning module, a 4G transmission module, a controller, and an alarm mechanism.

A fixing plate is fixedly connected to the upper end of the rectangular frame, and a protective box is fixedly connected to the upper surface of the fixing plate. The water flooding detection mechanism is connected inside the lower end of the rectangular frame. The water flooding detection mechanism includes a partition, a waterproof pressure sensor, and a float. A partition is fixedly connected to the lower end of the rectangular frame, and a waterproof pressure sensor is installed on the lower surface of the partition. A float is located inside the lower end of the rectangular frame. A GPS positioning module is installed on the inner lower surface of the protective box.

[0013] Compared with related technologies, the drilling platform auxiliary positioning and early warning device provided by this utility model has the following beneficial effects:

[0014] This invention provides an auxiliary positioning and early warning device for drilling platforms. By combining a float ball with a waterproof pressure sensor, it avoids instantaneous wave interference and can accurately detect flooding conditions, avoiding the false alarm problems of traditional water level sensors. Simultaneously, it integrates a GPS positioning module to monitor the platform's position in real time. Once the platform exceeds the safe range, it immediately triggers a deviation warning, achieving multi-dimensional safety monitoring.

Furthermore, the controller automatically judges abnormal states based on preset thresholds and triggers the first and second audible and visual alarms, ensuring that personnel detect dangers as soon as possible, shortening emergency response time. The alarm information and platform coordinates are uploaded to the cloud platform in real time via a 4G transmission module, facilitating the remote management center to promptly grasp the on-site situation and allocate resources.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the present invention from another angle; Figure 3 This is a schematic diagram of the internal structure of the protective box in this utility model. It includes: a rectangular frame 1, a flood detection mechanism, a GPS positioning module 19, a 4G transmission module 2, a controller 18, and an alarm mechanism.

[0021] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, a U-shaped mounting plate 3 is fixedly fitted onto the front and rear faces of the lower end of the rectangular frame 1. A through cavity 16 is opened on both sides of the lower end of the rectangular frame 1. A fixing plate 5 is fixedly connected to the upper end of the rectangular frame 1, and a protective box 6 is fixedly connected to the upper surface of the fixing plate 5. A flood detection mechanism is connected inside the lower end of the rectangular frame 1. The flood detection mechanism includes a partition 13, a waterproof pressure sensor 14, and a float 15. A partition 13 is fixedly connected to the lower end of the rectangular frame 1, and a waterproof pressure sensor 14 is installed on the lower surface of the partition 13. A float 15 is provided inside the lower end of the rectangular frame 1. The protective box 6... A GPS positioning module 19 is installed on the inner lower surface of the protective box 6, and a 4G transmission module 2 is installed on the inner lower surface of the protective box 6 (both the GPS antenna of the GPS positioning module 19 and the 4G antenna of the 4G transmission module 2 are installed on the upper surface of the protective box 6). A controller 18 is installed on the inner lower surface of the protective box 6, and an alarm mechanism is installed on the upper surface of the protective box 6. The alarm mechanism includes a first audible and visual alarm 8 and a second audible and visual alarm 9. The waterproof pressure sensor 14, the GPS positioning module 19, the 4G transmission module 2, the first audible and visual alarm 8 and the second audible and visual alarm 9 are all electrically connected to the controller 18.

[0022] It should be noted that during use, the device is installed on the offshore drilling platform via the U-shaped mounting plate 3. When flooding occurs, water will enter the lower end of the rectangular frame 1 through the cavity 16. The float 15 will rise due to buoyancy, pressing the waterproof pressure sensor 14 on the lower surface of the partition 13. The waterproof pressure sensor 14 transmits the detected signal to the controller 18. When the pressure continuously exceeds the preset threshold (pressure magnitude and time) in the controller 18, the controller 18 will activate the first audible and visual alarm 8 to sound an alarm and transmit the information to the control center via the 4G transmission module 2. The GPS positioning module 19 can locate and obtain the latitude and longitude of the drilling platform in real time during use. The GPS positioning module 19 transmits the detected signal to the controller 18. When the distance exceeds the preset safe coordinate range in the controller 18, an offset warning is triggered. The controller 18 will activate the second audible and visual alarm 9 to sound an alarm and transmit the information to the control center via the 4G transmission module 2.

[0023] refer to Figure 1 As shown, the U-shaped mounting plate 3 has multiple evenly distributed mounting holes 4, which facilitate the installation and fixing of the U-shaped mounting plate 3.

[0024] refer to Figure 2 As shown, ribs 17 are fixedly connected to the sides of the rectangular frame 1. The upper surface of the ribs 17 is fixedly connected to the lower surface of the fixing plate 5. The ribs 17 make the structure of the fixing plate 5 more stable.

[0025] refer to Figure 1 As shown, multiple evenly distributed heat dissipation pipes 11 are fixedly connected to both sides of the protective box 6. A waterproof and breathable valve 12 is installed at one end of the heat dissipation pipe 11. The heat dissipation pipe 11 with the waterproof and breathable valve 12 installed can play a role in waterproofing and heat dissipation.

[0026] refer to Figure 1 As shown, the front end of the protective box 6 has a door cavity, and a matching box door 10 is installed inside the door cavity. The box door 10 facilitates maintenance and repair inside the protective box 6.

[0027] refer to Figure 1 As shown, L-shaped connecting strips 7 are fixedly connected to the four corners of the outer surface of the protective box 6. The L-shaped connecting strips 7 are fixedly connected to the upper surface of the fixing plate 5 by bolts, which facilitates the assembly and disassembly of the protective box 6.

[0028] The working principle of this utility model is as follows: During use, the device is installed on the offshore drilling platform via the U-shaped mounting plate 3. When flooding occurs, water flows through the cavity 16 into the lower end of the rectangular frame 1. The float 15 rises due to buoyancy, pressing the waterproof pressure sensor 14 on the lower surface of the partition 13. The waterproof pressure sensor 14 transmits the detected signal to the controller 18. When the pressure continuously exceeds the preset threshold (pressure magnitude and time) within the controller 18, the controller 18 activates the first audible and visual alarm 8 to issue an alarm and transmits the information to the control center via the 4G transmission module 2. Meanwhile, the GPS positioning module 19 can obtain the latitude and longitude of the drilling platform in real time during use. The GPS positioning module 19 transmits the detected signal to the controller 18. When the distance exceeds the preset safe coordinate range within the controller 18, an offset warning is triggered. The controller 18 then activates the second audible and visual alarm 9 to issue a warning and transmits the information to the control center via the 4G transmission module 2. The device transmits information to the control center. Through the cooperation of the float 15 and the waterproof pressure sensor 14, it avoids the instantaneous interference of waves and can accurately detect flooding. It avoids the false alarm problem of traditional water level sensors. At the same time, it combines the GPS positioning module 19 to monitor the platform position in real time. Once it exceeds the safe range, it immediately triggers the offset warning, realizing multi-dimensional safety monitoring. The flooding alarm and offset warning operate simultaneously, which can analyze risks in a coordinated manner and analyze whether the water ingress is caused by drift, shortening the decision time and thus optimizing the emergency response. Moreover, the controller 18 automatically judges the abnormal state according to the preset threshold and triggers the first audible and visual alarm 8 and the second audible and visual alarm 9 to ensure that the staff can discover the danger as soon as possible and shorten the emergency response time. Furthermore, the alarm information and platform coordinates are uploaded to the cloud platform in real time through the 4G transmission module 2, which makes it easy for the remote management center to grasp the on-site situation and dispatch resources in a timely manner. It is especially suitable for unattended or harsh operating scenarios.
