Description

Technical Field

[0001] This application relates to the field of coolers, and more specifically, to low-noise explosion-proof air coolers for offshore platforms. Background Technology

[0002] The primary function of wind turbines on offshore platforms is to utilize abundant offshore wind energy resources to generate electricity, providing partial power support for the platforms and helping to reduce dependence on traditional energy sources, thus achieving energy conservation and emission reduction. During operation, some internal components of the wind turbine generate heat. If not cooled in time, this can affect its efficiency and lifespan. Air-to-air coolers help dissipate this heat, maintaining the wind turbine in optimal operating condition. An air-to-air cooler, also known as an air cooler, uses air as the cooling medium to reduce the temperature of the high-temperature fluid inside the tubes through heat exchange. Using air as the coolant, it can function as both a cooler and a condenser. An air cooler mainly consists of tube bundles, supports, and a fan. Ventilation can be achieved through forced draft or induced draft. The hot fluid flows inside the tubes, while air blows over the outside of the tube bundle, thus achieving heat exchange and cooling. Using air coolers can save significant amounts of industrial water, reduce environmental pollution, and lower infrastructure costs. Especially in water-scarce regions, replacing water cooling with air cooling can alleviate the problem of insufficient water resources.

[0003] The patent document with publication number CN119122765A discloses a low-noise explosion-proof air cooler for offshore platforms, which relates to the field of cooler technology. It includes an air cooler assembly, on the outer surface of which a cleaning component for cleaning putty is fixedly connected. The outer surface of the cleaning component is fixedly connected to a pneumatic component for driving the operation of the cleaning component. The cleaning component includes two fixed cylinders and multiple cleaning rings.

[0004] The aforementioned application document describes a cleaning component that moves back and forth alternately to both ends, enabling the cleaning ring to clean the outer surface of the heat exchange tube. However, external dust can easily enter through the slots reserved on the outer shell to accommodate the reciprocating movement of the cleaning component, making it easy for the outer surface of the heat exchange tube to accumulate more dust. This makes it difficult to reduce the amount of dust on the heat exchange tube by blocking external dust. Summary of the Invention

[0025] Example 1, see Figures 1-8This embodiment provides a low-noise explosion-proof air cooler for offshore platforms, including a sound-absorbing shell 1. The outer surface of the sound-absorbing shell 1 is made of metal, and the inner surface is provided with a glass wool layer for sound absorption and noise reduction. Two air inlet dustproof nets 2 are fixedly connected to the top of the sound-absorbing shell 1. The portion of the top of the sound-absorbing shell 1 covered by the air inlet dustproof nets 2 has a perforation for air intake. A cooling assembly 3 is provided on the inner surface of the sound-absorbing shell 1. The cooling assembly 3 includes a heat exchange pipe 301, which is U-shaped and penetrates and is fixedly connected to the left side of the sound-absorbing shell 1. A connecting chamber 302 is fixedly connected to the right side of the sound-absorbing shell 1. A partition plate is provided on the inner surface of the connecting chamber 302, dividing the inner surface of the connecting chamber 302 into upper and lower sections. In the domain, an air inlet flange 303 is fixedly connected to the right side of the connecting chamber 302. The air inlet flange 303 is used to introduce external gas to be cooled. A fan 304 is fixedly installed on the top of the connecting chamber 302. The air inlet end of the fan 304 is also connected to the top of the connecting chamber 302 and is connected to the inner surface of the connecting chamber 302. The fan 304 generates suction to draw in the gas. An air outlet flange 309 is fixedly connected to the right end of the fan 304. The air outlet flange 309 is connected to the air outlet end of the fan 304 and is used to discharge the cooled gas. A base 305 is fixedly connected to the bottom of the sound-absorbing shell 1. The base 305 is connected to the inner surface of the sound-absorbing shell 1. Four mounting seats 306 are fixedly connected to the bottom of the base 305. The sound-absorbing housing 1 is C-shaped and reinforced with ribs welded to the base 305. A collection box 307 is slidably connected to the inner surface of the base 305. The collection box 307 and the base 305 have a drawer-type structure and are equipped with a latch for fixing to the base 305. It is used to collect some impurities or oil stains pushed down from the heat exchange tube 301 inside the sound-absorbing housing 1. The top of the sound-absorbing housing 1 has an opening, and a fan device 308 is rotatably connected to the inner surface of the opening. There are two openings and two fan devices 308 on the top of the sound-absorbing housing 1. The fan device 308 includes a housing and fan blades for supporting and driving the fan blades to rotate. A dustproof net is provided at the bottom of the housing to prevent external dust from entering the sound-absorbing housing 1 from the fan device 308. This is a prior art device used for cleaning the sound-absorbing housing. A suction force is generated inside the shell 1, causing hot air inside the sound-absorbing shell 1 to be drawn out. Simultaneously, external air enters the sound-absorbing shell 1 through the dust filter 2 at the air inlet, thus facilitating airflow within the sound-absorbing shell 1 and cooling the heat exchange tube 301. The fan device 308 is rotatably connected to the opening at the top of the sound-absorbing shell 1 at the middle of its left and right sides, allowing the fan device 308 to move back and forth within the opening at the top of the sound-absorbing shell 1. A cleaning component 4 is provided on the inner surface of the sound-absorbing shell 1. The cleaning component 4 includes a cleaning plate 401, which is slidably connected to the outer surface of the heat exchange tube 301. The cleaning plate 401 is sleeved on the outer surface of the heat exchange tube 301, and a layer of silicone material with good heat dissipation performance is provided at the contact point between the cleaning plate 401 and the outer surface of the heat exchange tube 301.The cleaning plate 401 is used to clean impurities on the outer surface of the heat exchange tube 301 while assisting in the dissipation of heat transferred from the heat exchange tube 301. Connecting strips 402 are fixedly connected to both the front and rear sides of the cleaning plate 401. There are four cleaning plates 401 and two connecting strips 402. A driving component 5 is provided on the back of the cleaning component 4. The driving component 5 includes a receiving chamber 501, which is fixedly connected to the back of the sound-absorbing shell 1. Like the sound-absorbing shell 1, the receiving chamber 501 has a metal outer surface and a glass wool layer on its inner surface for sound absorption and noise reduction. The receiving chamber 501 is connected to the inner surface of the sound-absorbing housing 1. A partition 502, L-shaped, is fixedly connected to the inner surface of the receiving chamber 501, dividing the receiving chamber 501 into two parts. The left part is an independent, sealed space, while the right part is connected to the inner surface of the sound-absorbing housing 1. A servo motor 503 is fixedly connected to the back of the sound-absorbing housing 1. The output end of the servo motor 503 is fixedly connected to a rotating shaft 504 via a coupling. The rotating shaft 504 passes through and rotatably connects to the right side of the receiving chamber 501 and the partition 502. The rotating shaft 504 is connected to the receiving chamber 501. A bearing is installed at the through-hole between the partition 501 and the diaphragm 502. The rotating shaft 504 is rotatably connected to the left side of the inner surface of the receiving chamber 501. The drive assembly 5 also includes a reciprocating screw 505, which is fixedly connected to the outer surface of the rotating shaft 504. A screw nut 506 is threaded onto the outer surface of the reciprocating screw 505. The rotation of the reciprocating screw 505 can drive the screw nut 506 to move back and forth. A connecting rod 507 is fixedly connected to the bottom of the screw nut 506. The connecting rod 507 has two right-angle bends. The connecting rod 507 is connected to the partition 502. 2. A through-and sliding connection is made on the right side. The connecting rod 507 is fixedly connected to the back of the connecting strip 402. The connecting rod 507 is used to push the connecting strip 402 to move left and right, while cooperating with the through-and-through connection of the partition 502 to limit the movement of the lead screw nut 506, so that the rotation of the reciprocating lead screw 505 can drive the lead screw nut 506 to move back and forth stably. The bottom of the fan device 308 is equipped with a swing assembly 6 for driving the fan device 308 to swing. The top of the air inlet dustproof screen 2 is equipped with a sweeping assembly 7 for cleaning dust on the air inlet dustproof screen 2.

[0026] In practical use, the above-mentioned equipment first generates suction by starting the fan 304, then the external gas to be cooled is introduced into the lower half of the connecting chamber 302 through the air inlet flange 303. The gas to be cooled is drawn by the fan 304, then passes through the heat exchange tube 301 and the upper half of the connecting chamber 302 into the fan 304, and then exits from the air outlet flange 309. At this time, the fan device 308 is started, which generates suction inside the sound-absorbing shell 1, causing the hot air inside the sound-absorbing shell 1 to be drawn out. At the same time, external air enters the sound-absorbing shell 1 through the air inlet dustproof net 2 to exchange and circulate the air inside the sound-absorbing shell 1, thereby cooling the heat exchange tube 301. At this time, dust and impurities in the external air are blocked by the air inlet dustproof net 2, making it difficult for them to enter the sound-absorbing shell 1. The external gas to be cooled is cooled after entering the heat exchange tube 301 and then blown by the fan 304. 04. When it is necessary to clean the heat exchange tube 301, the servo motor 503 is started to drive the rotating shaft 504 to rotate. The rotation of the rotating shaft 504 will drive the reciprocating screw 505 to rotate. The rotation of the reciprocating screw 505 will drive the screw nut 506 to move back and forth. The left and right reciprocating movement of the screw nut 506 will drive the connecting rod 507 to push back and forth, thereby pushing the connecting bar 402 to make the cleaning plate 401 slide left and right on the outer surface of the heat exchange tube 301. At this time, the cleaning plate 401 will push the dust, impurities and oil stains accumulated on the outer surface of the heat exchange tube 301 to a concentrated position, so that a large part of the heat exchange tube 301 is not covered by impurities, thus ensuring the heat exchange performance of the heat exchange tube 301. The dust, impurities and oil stains pushed aside will fall under the action of gravity and fall into the collection box 307 in the base 305. The collection box 307 is pulled out from the base 305 to clean these impurities.

[0027] Example 2, see Figures 1-8The oscillating component 6 includes two sealing frames 601, which are respectively mounted on the two fan devices 308 and connected to the outer shell of the fan devices 308. The sealing frames 601 are U-shaped, with arc surfaces on their front and rear sides. The center of the arc surface is concentric with the rotation connection point of the outer shell of the fan device 308 in the opening at the top of the sound-absorbing outer shell 1. The sealing frames 601 are fixedly connected to the outer surface of the fan devices 308. Arc plates 602 are slidably connected to both ends of the sealing frames 601. The arc plates 602 are fixedly connected to the inner surface of the sound-absorbing outer shell 1 and are connected to the opening at the top of the sound-absorbing outer shell 1. Two connecting plates 603 are fixedly connected to the bottom of the fan devices 308 and the inner surface of the sealing frames 601. A connecting post is fixedly connected between the two connecting plates 603. 604. The swing assembly 6 also includes a vertical plate 605, which is fixedly connected to the top of the inner surface of the sound-absorbing housing 1. A rotating rod 606 is rotatably connected through the left side of the vertical plate 605. A bearing is provided between the rotating rod 606 and the vertical plate 605. A chain 607 is connected between the rotating rod 606 and the rotating shaft 504. A sprocket for the chain 607 to drive the rotation is provided on the outer surface of the rotating rod 606 and the rotating shaft 504. A turntable 608 is fixedly connected to the left end of the rotating rod 606. A push rod 609 is rotatably connected to the left side of the turntable 608. The rotation connection point between the push rod 609 and the turntable 608 is eccentrically set on the turntable 608. A rotating sleeve 610 is fixedly connected to the front of the push rod 609. The rotating sleeve 610 is rotatably connected to the outer surface of the connecting column 604. A bearing is provided between the rotating sleeve 610 and the connecting column 604.

[0028] In practical use, when the servo motor 503 drives the rotating shaft 504 to rotate, the rotation of the rotating shaft 504 also drives the chain 607 to rotate the rotating rod 606 within the vertical plate 605. The rotation of the rotating rod 606 drives the turntable 608 to rotate. The rotation of the turntable 608 causes the rotating connection point between the push rod 609 and the turntable 608 to rotate around the rotation axis of the turntable 608. At this time, the other end of the push rod 609 will move back and forth, thereby driving the rotating sleeve 610 to move the connecting column 604 back and forth. When the fan device 308 moves, the connecting column 604 will drive the connecting plate 603 to swing the fan device 308 back and forth, thereby enhancing the air circulation effect inside the sound-absorbing housing 1 and thus strengthening the heat dissipation effect of the sound-absorbing housing 1. While the fan device 308 swings back and forth, it will drive the sealing frame 601 to slide on the arc plates 602 at its front and rear ends, thereby sealing the empty space in the moving area while maintaining the movement, making it difficult for external dust to enter. At the same time, the dustproof net inside the fan device 308 makes it difficult for dust to enter the sound-absorbing housing 1 through the stopped fan device 308.

[0029] Example 3, see Figures 1-8The sweeping assembly 7 includes a rack 701, which is slidably connected to the top of the sound-absorbing housing 1. A slide rail is provided on the top of the sound-absorbing housing 1 for the rack 701 to slide back and forth. The slide rail has a trapezoidal cross-sectional shape. A dovetail groove adapted to the slide rail is provided at the bottom of the rack 701. Gears 702 mesh on both sides of the rack 701. A rotating column 703 is passed through and fixedly connected to the top of the gear 702. There are two gears 702 and rotating columns 703. The rotating columns 703 are rotatably connected to the top of the sound-absorbing housing 1, and their outer surfaces are fixedly connected to... A swing bar 704 is connected, and a guide groove 705 is opened at the top of the swing bar 704. The guide groove 705 is through-hole, and a guide rod 706 is slidably connected to the inner surface of the guide groove 705. A cleaning brush 707 is fixedly connected to the lower end of the guide rod 706. The guide rod 706 has a T-shaped side cross-section and is connected to the back of the cleaning brush 707. The back of the cleaning brush 707 is wider than its bristles. The cleaning brush 707 is slidably connected to the top of the air inlet dust filter 2 and is used to sweep away dust and impurities on the air inlet dust filter 2. The cleaning brush 707 has two sides. Each side is fixedly connected to a sliding sleeve 708. A sliding rod 709, C-shaped, is slidably connected to the inner surface of the sliding sleeve 708 and is fixedly connected to the outer surface of the sound-absorbing housing 1. The sweeping assembly 7 also includes a first hydraulic chamber 710, which penetrates and is fixedly connected to the right side of the partition 502. A first hydraulic rod 711 is slidably connected to the inner surface of the first hydraulic chamber 710 and is fixedly connected to the connecting rod 507. A second hydraulic chamber 712 is fixedly connected to the top of the sound-absorbing housing 1. A pipe 713 connects the hydraulic chamber 712 and the first hydraulic chamber 710. The second hydraulic chamber 712 is connected to the first hydraulic chamber 710 via the pipe 713. Hydraulic oil is contained in the second hydraulic chamber 712, the first hydraulic chamber 710, and the pipe 713. The second hydraulic chamber 712 and the first hydraulic chamber 710 have the same volume. The pipe 713 passes through and is slidably connected to the back of the receiving chamber 501. A second hydraulic rod 714 is slidably connected to the inner surface of the second hydraulic chamber 712. The second hydraulic rod 714 is fixedly connected to the rear end of the rack 701.

[0030] In practical use, when the lead screw nut 506 drives the connecting rod 507 to move back and forth, the connecting rod 507 also drives the first hydraulic rod 711 to slide back and forth within the first hydraulic chamber 710. When the first hydraulic rod 711 slides to the right, it pushes the liquid in the first hydraulic chamber 710 into the second hydraulic chamber 712, causing the second hydraulic rod 714 to extend from the second hydraulic chamber 712. At this time, the second hydraulic rod 714 will slide forward. When the first hydraulic rod 711 slides to the left, it draws the liquid from the second hydraulic chamber 712 into the first hydraulic chamber 710, causing the second hydraulic rod 714 to retract from the second hydraulic chamber 712. The rod 714 slides backward. The back-and-forth sliding of the second hydraulic rod 714 drives the rack 701 to slide back and forth on the sound-absorbing housing 1. The rack 701 drives the gear 702 to make the rotating column 703 rotate slightly forward and backward, which in turn drives the swing bar 704 to swing back and forth continuously. The swing bar 704 drives the guide groove 705 to push the guide rod 706 back and forth, which in turn drives the cleaning brush 707 to make the sliding sleeve 708 slide back and forth on the sliding rod 709. At this time, the cleaning brush 707 will sweep back and forth on the air inlet dustproof screen 2. The cleaning brush 707 will sweep away the dust and impurities accumulated on the air inlet dustproof screen 2, thereby ensuring the unobstructed air inlet dustproof screen 2.
