Description

Technical Field

[0001] This utility model relates to the field of petroleum technology, and in particular to a hydrogen sulfide monitoring and alarm device for offshore oil production platforms. Background Technology

[0002] Offshore platforms, large truss structures standing on the sea surface with expansive decks, are indispensable facilities in the field of marine resource development. People often rely on these platforms to carry out critical operations such as drilling, exploring and excavating the treasures of the deep ocean. Given the extremely rich oil resources hidden beneath the sea, in recent years, humanity has given unprecedented attention to the development and utilization of marine resources.

[0003] However, a significant safety hazard lurks in the oil and gas extraction process – hydrogen sulfide. This gas is not only highly toxic and emits an unbearable, pungent odor, but it also poses a direct threat to the lives of on-site workers. Even more serious is that hydrogen sulfide exhibits strong corrosiveness to metal structures such as production equipment and gathering pipelines throughout all stages of oil and gas extraction, transportation, and storage, easily triggering "hydrogen embrittlement" and potentially leading to catastrophic safety accidents.

[0004] Therefore, this application proposes a hydrogen sulfide monitoring and alarm device for offshore oil production platforms. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing a hydrogen sulfide monitoring and alarm device for offshore oil production platforms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydrogen sulfide monitoring and alarm device for offshore oil production platforms includes a connector that can be installed on the platform. The connector is installed on the platform via a connecting mechanism. The connector has a housing, on which a controller, an alarm, and a hydrogen sulfide monitoring device are installed. The controller is connected to the alarm and the hydrogen sulfide monitoring device. The housing has a fan and an air inlet pipe, and an air inlet hood is installed on the air inlet pipe. When the fan is working, it can draw outside air into the housing through the air inlet hood and the air inlet pipe, where it is detected by the hydrogen sulfide monitoring device. The housing has a heat insulation cover, and a heat insulation plate that is rotatably connected to the heat insulation cover is limited.

[0008] Preferably, the connecting mechanism includes four bolt holes that pass through the connecting seat, and the four bolt holes are arranged in a rectangular pattern.

[0009] Preferably, the housing is fixed with four fixing ears, which are fixed to the connecting seat by bolts.

[0010] Preferably, a first magnetic strip is fixed on the heat insulation plate, and a second magnetic strip is fixed on the heat insulation cover, with the first magnetic strip and the second magnetic strip abutting against each other.

[0011] Preferably, the magnetic poles of the sides of the first magnetic strip and the second magnetic strip that are in contact with each other have opposite polarities.

[0012] Preferably, the heat insulation cover is equipped with a glass observation window.

[0013] Preferably, the air inlet pipe is a metal-shaped flexible hose.

[0014] Preferably, the connecting mechanism includes a mounting frame fixed on the platform, the connecting seat is slidably connected in the mounting frame, the connecting seat is provided with two locking grooves, and a slidably disposed locking pin is provided through the mounting frame, the locking pin being slidably connected in the locking grooves.

[0015] Preferably, a spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the mounting frame.

[0016] Preferably, the air inlet end of the fan is equipped with an air intake pipe, which is connected to a heat insulation cover, and an air inlet slot is provided through the heat insulation cover.

[0017] Compared with the prior art, the advantages of this utility model are as follows:

[0018] 1. Employing electrochemical or semiconductor sensors, these sensors feature high sensitivity, rapid response, and long-term stability, enabling precise detection of hydrogen sulfide concentration in the air and timely identification of potential hydrogen sulfide leaks, thus providing valuable response time for platform personnel.

[0019] 2. The heat insulation cover is made of multiple layers of heat insulation materials, such as aluminum silicate fiber felt and aluminum foil, which can effectively block the influence of high external temperature on the equipment inside the enclosure. At the same time, it can also prevent the heat generated by the equipment inside the enclosure from dissipating into the external environment, providing a stable working temperature environment for the equipment inside the enclosure and ensuring the normal operation of the equipment.

[0020] 3. An air intake pipe is installed at the air inlet of the fan and connected to the heat insulation cover. An air inlet slot is provided through the heat insulation cover. When the fan is working, the air intake pipe exhausts the air inside the heat insulation cover, and outside air enters the heat insulation cover through the air inlet slot, thereby replacing the air inside the heat insulation cover, enhancing air circulation, facilitating heat dissipation for equipment such as alarms, ensuring that the equipment operates at a suitable temperature, and improving the stability and reliability of equipment operation.

[0021] 4. First, firmly weld the mounting frame to the platform and conduct a comprehensive quality inspection. Then, install the connecting seat inside the mounting frame and pull the locking pin. When the connecting seat slides to abut against the platform, the locking pin automatically springs into the locking groove under the action of the spring, achieving a quick and stable connection between the connecting seat and the mounting frame. To disassemble the connecting seat, simply hold the locking pin and pull it outward to remove it from the locking groove, then slide the connecting seat out along the guide rail. The entire installation and disassembly process is simple and convenient, requiring no complicated tools, greatly improving work efficiency, and also facilitating the maintenance and repair of the device. The operation is simple and convenient.

[0022] In summary, this invention can accurately detect the concentration of hydrogen sulfide in the air, promptly identify potential hydrogen sulfide leakage hazards, and buy valuable response time for platform personnel; it can effectively block the impact of high external temperatures on the equipment inside the enclosure, while also preventing the heat generated by the equipment inside the enclosure from dissipating into the external environment, providing a stable operating temperature environment for the equipment inside the enclosure and ensuring normal operation of the equipment.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This hydrogen sulfide monitoring and alarm device for offshore oil platforms includes a connector 1 that can be securely mounted on the platform. The connector 1 is reliably mounted on the platform via a high-strength connection mechanism to withstand the harsh working conditions at sea. The connection mechanism includes four bolt holes 10 that penetrate the connector 1 in a rectangular arrangement. This layout ensures uniform stress on the connector 1 and improves installation stability. During installation, high-strength fixing bolts are used to firmly secure the connector 1 to the platform through the bolt holes 10. The fixing bolts should be made of corrosion-resistant, high-strength alloy material, such as 316L stainless steel, to prevent rust and corrosion in the humid and salt spray environment at sea, ensuring long-term reliability.

[0033] The connecting seat 1 is equipped with a protective enclosure 2, which is made of high-strength, corrosion-resistant engineering plastic or stainless steel to withstand wind and rain erosion and possible collisions at sea. The enclosure 2 is fixed with four fixing ears 9, which are fixed to the connecting seat 1 by high-strength bolts. The bolts should be equipped with anti-loosening washers to prevent loosening under platform vibration.

[0034] The housing 2 is equipped with a controller 13, an alarm 14, and a hydrogen sulfide monitoring device 15. The controller 13 uses microprocessor control technology and has data processing, logic judgment, and communication functions. It can receive detection data from the hydrogen sulfide monitoring device 15 in real time and make judgments based on preset thresholds. The controller 13 is connected to the alarm 14 and the hydrogen sulfide monitoring device 15 via a shielded cable. The shielded cable effectively prevents electromagnetic interference at sea from affecting signal transmission, ensuring the accuracy and stability of data transmission. The hydrogen sulfide monitoring device 15 uses an electrochemical sensor or a semiconductor sensor, featuring high sensitivity, fast response, and long-term stability, and can accurately detect the concentration of hydrogen sulfide in the air. The alarm 14 uses an audible and visual alarm method. When the detected hydrogen sulfide concentration exceeds the set value, it emits a loud alarm sound and flashes a conspicuous warning light, promptly reminding platform personnel to take safety measures.

[0035] The housing 2 is also equipped with a fan 5 for ventilation, heat dissipation, and air sampling, as well as an air inlet duct 3. The air inlet duct 3 is a flexible metal hose with good flexibility and corrosion resistance, allowing for easy adjustment of the air intake direction and position. An air inlet hood 4 is installed on the air inlet duct 3. The air inlet hood 4 is designed to be rainproof and insect-proof, and its opening should avoid directly facing the sea surface or strong winds to prevent seawater and debris from entering the air inlet duct 3. The fan 5, when operating, stably draws outside air into the housing 2 through the air inlet hood 4 and the air inlet duct 3, ensuring that the air flows evenly across the detection area of ​​the hydrogen sulfide monitoring equipment 15, thus ensuring the accuracy of the detection results.

[0036] A heat insulation cover 8 is installed on the enclosure 2. The heat insulation cover 8 is made of multi-layer heat insulation materials, such as aluminum silicate fiber felt and aluminum foil, which can effectively block the influence of high external temperatures on the equipment inside the enclosure 2, and also prevent the heat generated by the equipment inside the enclosure 2 from dissipating into the external environment. A limited heat insulation plate 7 is rotatably connected to the heat insulation cover 8. The heat insulation plate 7 can rotate within a certain angle range, which facilitates maintenance and repair of the equipment inside the enclosure 2 by the staff. A first magnetic strip 11 is fixed on the heat insulation plate 7, and a second magnetic strip 12 is fixed on the heat insulation cover 8. The first magnetic strip 11 and the second magnetic strip 12 abut against each other. The magnetic poles of the sides of the first magnetic strip 11 and the second magnetic strip 12 that abut against each other have opposite polarities. This design allows the heat insulation plate 7 to fit tightly against the heat insulation cover 8 when closed, improving the heat insulation effect, and also preventing the heat insulation plate 7 from opening on its own under platform vibration.

[0037] In addition, a glass observation window is installed on the heat shield 8. The glass observation window is made of high-strength, corrosion-resistant tempered glass, which has good light transmission and impact resistance. Personnel can observe the working status of the alarm 14 in real time through the glass observation window without opening the heat shield 7, which is both convenient and safe. At the same time, to prevent glare from affecting the observation effect in the strong sunlight environment at sea, an anti-reflective treatment can be applied to the surface of the glass observation window.

[0038] Example 2

[0039] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the connecting mechanism in this embodiment includes a mounting frame 16 fixed on the platform, a connecting seat 1 slidably connected in the mounting frame 16, two locking grooves 20 on the connecting seat 1, a sliding locking pin 17 through the mounting frame 16, the locking pin 17 slidably connected in the locking groove 20, a spring 18 fixedly connected to the locking pin 17, and the other end of the spring 18 fixedly connected to the mounting frame 16.

[0040] In use, first firmly weld the mounting frame 16 to the platform and perform a comprehensive quality inspection. Then, install the connecting seat 1 inside the mounting frame 16 and pull the locking pin 17 to move it. When the connecting seat 1 slides to abut against the platform, the locking pin 17 automatically springs into the locking groove 20 under the action of the spring 18, achieving a quick and stable connection between the connecting seat 1 and the mounting frame 16. To disassemble the connecting seat 1, simply hold the locking pin 17 and pull it outward to remove it from the locking groove 20, then slide the connecting seat 1 along the guide rail. The entire installation and disassembly process is simple and convenient, requiring no complicated tools, greatly improving work efficiency, and also facilitating the maintenance and repair of the device.

[0041] Example 3

[0042] Reference Figures 5-6 The difference between this embodiment and embodiments 1 and 2 is that in this embodiment, the air inlet end of the fan 5 is equipped with an air intake pipe 19, the air intake pipe 19 is connected to the heat insulation cover 8, and the heat insulation cover 8 is provided with an air inlet slot 6.

[0043] When the fan 5 is working, the air inside the heat insulation cover 8 can be discharged through the air intake pipe 19, and the outside air enters the heat insulation cover 8 through the air inlet slot 6. This achieves the replacement of the air inside the heat insulation cover 8, and the air circulation is conducive to the heat dissipation of the alarm 14 and other devices.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
