Description

Technical Field

[0001] This utility model relates to an air compressor device, and more particularly to an air compressor device for offshore drilling platforms. Background Technology

[0002] Air compressors for offshore drilling platforms are among the key pieces of equipment, primarily providing compressed air for drilling operations. Due to the unique marine environment, air compressors are susceptible to damage from salt spray, moisture, and corrosive substances during operation. These factors can cause corrosion of the compressor's metal components, thus affecting its performance and lifespan.

[0003] Due to the limited space on offshore drilling platforms, the installation space for air compressors is also very limited. Currently, the space next to the air compressor enclosure is limited, making it difficult for people or objects to pass through. When electrical components such as the air compressor inside the enclosure need to be replaced or maintained, it is difficult to remove and replace these components from the enclosure, increasing the difficulty of maintenance. Therefore, there is an urgent need for an air compressor device that allows for easy replacement and maintenance of internal electrical components. Utility Model Content

[0004] The purpose of this utility model is to provide an air compressor device for offshore drilling platforms to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this utility model is:

[0006] An air compressor unit for an offshore drilling platform includes: a chassis having an upward-facing cavity, the side wall of the chassis having an opening communicating with the cavity, a top beam connected to the opening on the inside of the chassis, the top beam dividing the opening into multiple hoisting inlets; a top cover connected to the top of the chassis and covering the opening; a door panel connected to the side wall of the chassis and covering the opening; and an air compressor assembly disposed inside the chassis.

[0007] This technical solution has at least the following beneficial effects: A cavity is formed inside the casing for installing the air compressor unit. A top beam is connected to the top of the casing to reinforce the structural stability of the casing opening. The top beam divides the casing opening into multiple lifting entrances according to the installation needs of various air compressor unit components. When installing or maintaining the air compressor unit, the various components can be installed into the cavity through the corresponding lifting entrances. The components can be connected and installed through openings in the side walls of the casing. After completion, the top cover and door panels cover and seal the openings in the side walls of the casing to protect the unit from theft. This reduces the space requirements of the casing environment, improves the convenience of air compressor unit installation and maintenance, and ensures a stable overall structure, which is beneficial for the stable and reliable operation of the air compressor unit in marine environments.

[0008] As a further improvement to the above technical solution, a downwardly protruding positioning post is provided on the bottom side of the door panel, and a positioning hole is provided on the bottom side of the housing located at the opening. The positioning post is inserted into the positioning hole. A door lock is provided on the inner side of the door panel, and the door lock has a latch that can be locked to the housing. When installing the door panel, the door panel can be placed into the opening from top to bottom. By utilizing the cooperation between the positioning post on the bottom side of the door panel and the positioning hole on the bottom side of the opening, the door panel can be quickly installed and positioned, and the latch of the door lock can be locked at the opening of the housing, thereby achieving quick installation and fixation of the door panel.

[0009] As a further improvement to the above technical solution, a drive shaft is provided inside the door lock. One end of the drive shaft extends to the outside of the door panel, and the other end is located on the inside of the door panel and connected to the latch. A retaining edge is provided on the inner side of the housing within the opening. The door panel abuts against the retaining edge, and the latch can rotate to abut against the retaining edge. When the door panel is placed into the opening, the retaining edge can block and limit the door panel, preventing it from further entering the cavity, thus improving the ease of positioning the door panel. Then, rotating the drive shaft from the outside of the door panel causes the latch located on the inside of the door panel to rotate, causing the latch to abut against the retaining edge, thereby preventing the door panel from falling out of the opening and achieving quick locking of the door panel, making it convenient to use.

[0010] As a further improvement to the above technical solution, the side of the top cover is bent to form a connecting flange, and an external hexagonal rivet nut is provided on the top side of the chassis. A connecting screw is passed through the connecting flange, and the connecting screw is engaged with the external hexagonal rivet nut for connection. The connecting flange of the top cover engages with the external hexagonal rivet nut on the top side of the chassis, and the tightening of the connecting screw achieves a firm installation and seal of the top cover. This connection method makes the connection structure less prone to slippage during installation, which not only simplifies the assembly process but also improves the stability and durability of the top cover, effectively preventing the top cover from loosening due to vibration and impact.

[0011] As a further improvement to the above technical solution, multiple top covers are arranged horizontally. This multi-layered horizontal arrangement of the top covers not only enhances their structural strength but also provides a larger hoisting entrance, facilitating the installation and maintenance of the air compressor components. Furthermore, this design allows for adjustments to the number and layout of the top covers according to actual needs, improving the adaptability and flexibility of the air compressor device.

[0012] As a further improvement to the above technical solution, a filter port is provided on the side wall of the chassis, and a filter screen is provided on the side wall of the chassis at the location of the filter port. The design of the filter port and filter screen on the side wall of the chassis effectively prevents excessive impurities and particulate matter from entering the chassis, protects the air compressor components from damage, and effectively prevents mosquitoes from entering the cavity, thus extending the service life and maintenance cycle of the air compressor components.

[0013] As a further improvement to the above technical solution, the air compressor assembly includes an air compressor, a cooler, and an air-water separator. The air compressor and the cooler are interconnected, and the cooler and the air-water separator are interconnected. The interconnection of the air compressor, cooler, and air-water separator forms a highly efficient and compact air compression and processing system. The cooler effectively reduces the temperature of the compressed air, while the air-water separator further removes moisture from the air, better recovers the moisture, and ensures the quality and stability of the output air.

[0014] As a further improvement to the above technical solution, a drain pipe is provided at the bottom of the cooler, and a drain valve is installed on the drain pipe. The design of the drain pipe and drain valve at the bottom of the cooler allows the water generated during the cooling process to be discharged in a timely manner, preventing corrosion and malfunctions caused by water accumulation. This drainage system not only improves the efficiency and reliability of the cooler, but also reduces maintenance costs and downtime.

[0015] As a further improvement to the above technical solution, the chassis includes a base and an outer frame, which together form the cavity. The top beam and the top cover are respectively connected to the outer frame, and the opening is located on the outer frame. The base includes square tubes and a panel, with multiple square tubes welded together to form a rectangular frame. The panels are connected to the top and bottom sides of the rectangular frame, and the outer frame is connected to the panel located on the top side. The design of the chassis's base and outer frame provides a robust and stable mounting platform for the air compressor assembly. The combination of the rectangular frame formed by welding the square tubes of the base and the panel enhances the structural strength and stability of the chassis, effectively reducing the intrusion of moisture from the connection gaps and better protecting the air compressor assembly inside the cavity.

[0016] As a further improvement to the above technical solution, a waterproof electrical box is provided on the side wall of the chassis. This waterproof electrical box design effectively prevents moisture and salt spray from corroding the internal electrical components, ensuring the safe operation of the electrical system. This not only improves the reliability and stability of the entire air compressor unit but also reduces the risk of downtime and maintenance costs due to electrical failures.

The various technical features in this invention can be combined interactively without contradicting each other.

[0023] Reference Figure 1 and Figure 2 An air compressor device for an offshore drilling platform includes: a housing 1, which encloses an upward-facing cavity; the side wall of the housing 1 has an opening communicating with the cavity; a top beam 11 is connected to the inside of the housing 1 at the opening; the top beam 11 divides the opening into multiple hoisting entrances; in practical applications, there can be multiple top beams 11, which are spliced ​​together along the horizontal or vertical direction to form hoisting entrances of different sizes; a top cover 2, which is connected to the top side of the housing 1 and covers the opening; a door panel 3, which is connected to the side wall of the housing 1 and covers the opening; there can be multiple door panels 3, and each side wall of the housing 1 can be provided with a door panel 3; and an air compressor assembly 4, which is disposed inside the housing 1.

[0024] In this air compressor unit for offshore drilling platforms, a cavity is formed inside the casing 1 for installing the air compressor unit. A top beam 11 is connected to the top of the casing 1 to reinforce the structural stability of the opening position of the casing 1. The top beam 11 is used to divide the opening position of the casing 1 into multiple lifting entrances according to the installation needs of various components of the air compressor unit. When it is necessary to install or maintain the air compressor unit, the various components inside the air compressor unit can be installed into the cavity through the corresponding lifting entrance. People can connect and install the components inside the air compressor unit through the openings in the side wall of the casing 1. After completion, the top cover 2 is used to cover and seal the opening at the top of the casing 1, and the door panel 3 is used to cover and seal the openings in the side wall of the casing 1 to protect the air compressor unit inside the casing 1 from theft. This reduces the space requirements of the environment where the casing 1 is located, improves the convenience of air compressor unit installation and maintenance, and the overall structure is stable, which is conducive to the stable and reliable operation of the air compressor unit in the marine environment.

[0025] Door panel 3 and chassis 1 are detachably connected. To facilitate positioning of door panel 3, such as... Figure 3As shown, in this embodiment, a downwardly protruding positioning post 31 is provided on the bottom side of the door panel 3, and a positioning hole is provided on the bottom side of the opening of the housing 1. The positioning post 31 is inserted into the positioning hole. A door lock 32 is provided on the inner side of the door panel 3, and the door lock 32 has a locking tongue 321 that can be locked to the housing 1. When installing the door panel 3, the door panel 3 can be placed into the opening from top to bottom. By utilizing the cooperation between the positioning post 31 on the bottom side of the door panel 3 and the positioning hole on the bottom side of the opening, the door panel 3 can be quickly installed and positioned, and the locking tongue 321 of the door lock 32 can be locked to the opening of the housing 1, thereby achieving quick installation and fixation of the door panel 3.

[0026] There are several ways to lock the latch 321 inside the door lock 32 to the housing 1. For example, an installation hole can be provided inside the housing 1 at the inner side of the opening. When it is necessary to lock and fix it to the housing 1, the latch 321 is inserted into the installation hole for connection and positioning. In order to further improve the convenience of positioning the door panel 3 into the opening, in this embodiment, a drive shaft is provided inside the door lock 32. One end of the drive shaft extends to the outside of the door panel 3, and the other end of the drive shaft is located inside the door panel 3 and connected to the latch 321. A retaining edge is provided inside the housing 1 at the inner side of the opening. The door panel 3 abuts against the retaining edge, and the latch 321 can rotate to abut against the retaining edge. When the door panel 3 is placed into the opening, the stop edge can block and limit the door panel 3, preventing the door panel 3 from entering the cavity further, thus improving the convenience of positioning the door panel 3. Then, the drive shaft is rotated from the outside of the door panel 3, which drives the lock tongue 321 located on the inside of the door panel 3 to rotate, so that the lock tongue 321 abuts against the stop edge, thereby preventing the door panel 3 from falling out of the opening and realizing quick locking of the door panel 3, which is convenient to use.

[0027] The top cover 2 is also detachably connected to the chassis 1. The two can be connected and fixed using snap-fit ​​mechanisms. To improve the stability of the connection structure, in this embodiment, the side of the top cover 2 is bent to form a connecting flange 21. An external hexagonal rivet nut is provided on the top side of the chassis 1, and a connecting screw passes through the connecting flange 21. The connecting screw engages with the external hexagonal rivet nut. The connecting flange 21 of the top cover 2 engages with the external hexagonal rivet nut on the top side of the chassis 1. Through the tightening of the connecting screw, a secure installation and seal of the top cover 2 is achieved. This connection method prevents slippage during installation, simplifying the assembly process and improving the stability and durability of the top cover 2, effectively preventing loosening due to vibration and impact.

[0028] Only one top cover 2 can be used, in which case the top cover 2 is relatively large, and the entire top cover 2 directly closes the opening. However, to improve the flexibility of assembling and disassembling the top cover 2, in this embodiment, multiple top covers 2 are arranged horizontally. The multiple arrangement of top covers 2 in the horizontal direction not only enhances the structural strength of the top cover 2, but also provides a larger hoisting entrance, facilitating the installation and maintenance of the air compressor assembly 4. In addition, this design allows the number and layout of top covers 2 to be adjusted according to actual needs, improving the adaptability and flexibility of the air compressor device.

[0029] To protect the air compressor unit from drawing air into the housing 1, in this embodiment, a filter port is provided on the side wall of the housing 1, and a filter screen 12 is provided on the side wall of the housing 1 at the location of the filter port. The design of the filter port and filter screen 12 on the side wall of the housing 1 effectively prevents excessive impurities and particulate matter from entering the housing 1, protects the air compressor assembly 4 from damage, and effectively prevents insects from entering the cavity, thus extending the service life and maintenance cycle of the air compressor assembly 4.

[0030] In some embodiments, the air compressor assembly 4 includes an air compressor, a cooler, and an air-water separator. The air compressor is connected to the cooler, and the cooler is connected to the air-water separator. The interconnection of the air compressor, cooler, and air-water separator forms a highly efficient and compact air compression and processing system. The cooler effectively reduces the temperature of the compressed air, while the air-water separator further removes moisture from the air, allowing for better moisture recovery and ensuring the quality and stability of the output air.

[0031] In some embodiments, a drain pipe with a drain valve is provided at the bottom of the cooler. The design of the drain pipe and drain valve at the bottom of the cooler allows water generated during the cooling process to be discharged in a timely manner, preventing corrosion and malfunctions caused by water accumulation. This drainage system not only improves the efficiency and reliability of the cooler but also reduces maintenance costs and downtime.

[0032] In some embodiments, the chassis 1 includes a base 13 and an outer frame 14, which together form the cavity. The top beam 11 and the top cover 2 are respectively connected to the outer frame 14, and the opening is provided on the outer frame 14. The base 13 includes a square tube and a panel, and multiple square tubes are welded together to form a rectangular frame. The upper and lower sides of the rectangular frame are respectively connected to the panel, and the outer frame 14 is connected to the panel located on the top side. The design of the base 13 and outer frame 14 of the chassis 1 provides a robust and stable mounting platform for the air compressor assembly 4. The combination of the rectangular frame formed by welding the square tubes of the base and the panel enhances the structural strength and stability of the chassis 1, effectively reduces the intrusion of moisture from the connection gaps, and better protects the air compressor assembly 4 inside the cavity.

[0033] In some embodiments, a waterproof electrical box 5 is provided on the side wall of the chassis 1. The waterproof electrical box 5 on the side wall of the chassis 1 effectively prevents moisture and salt spray from corroding the electrical components inside the box, ensuring the safe operation of the electrical system. This not only improves the reliability and stability of the entire air compressor unit, but also reduces the risk of downtime and maintenance costs due to electrical failures.
