Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically a bearing housing breathing structure for offshore platforms. Background Technology

[0002] The main function of the bearing housing breathing structure on offshore platforms is to balance the air pressure inside and outside the housing, prevent lubricating oil leakage or the entry of external impurities, and maintain the normal working environment of the gear set. The breathing structure balances the pressure difference inside and outside the housing by expelling high-temperature and high-pressure gas and drawing in low-temperature gas, thus avoiding damage to oil seals or lubricating oil leakage due to pressure imbalance.

[0003] Chinese patent CN221033671U discloses an adjustable bearing housing device, including a bearing housing shell and further comprising: a bearing housing disposed inside the bearing housing shell; a bearing housing base disposed at the bottom of the bearing housing, which drives the bearing housing to move upward; and a lifting mechanism disposed at the bottom of the bearing housing base, which drives a fixed rod to move upward through the upward movement of a hydraulic rod. When the fixed rod moves upward, it drives a linkage mechanism to retract inward, which in turn drives the bearing housing base to move upward, and then the bearing housing base drives the bearing housing to move upward to maintain the same horizontal line as the fan. Compared with traditional devices, this device adjusts the height of the bearing housing by lifting it, which facilitates connection with fans of different heights, avoids the need to replace the bearing housing, and improves the efficiency of use. The above technical solution solves the bearing housing problem in the prior art.

[0004] When bearing housings are used on seawater platforms, the air at sea is humid and salty. During breathing through a breathing cap, water vapor and salt spray can enter the bearing housing, causing the lubricating oil to emulsify, resulting in rust on the bearings and bearing housings, and ultimately damaging the unit. In addition, the sea is rough, with strong winds and heavy rain, and rain can come from any direction. Once rainwater enters the bearing housing, it can also cause the lubricating oil to emulsify, resulting in rust on the bearings and bearing housings, and ultimately damaging the unit. Utility Model Content

[0005] The purpose of this invention is to provide a bearing housing breathing structure for offshore platforms, in order to solve the problem mentioned in the background art that water vapor and salt spray can enter the bearing housing, thereby causing lubricating oil emulsification, resulting in rusting of the bearing and bearing housing, and ultimately damage to the unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing housing breathing structure for an offshore platform, comprising a bearing housing body, a breathing port being provided at the top of the bearing housing body, a transmission pipe being fixedly installed at the top of the breathing port, and a drying and protection component being provided at the bottom end of the transmission pipe; a limit support component being provided inside the drying and protection component, a disassembly plate being detachably connected to one side of the drying and protection component, and a detachable component being provided at the outer end of the disassembly plate;

[0007] Preferably, the drying and protection assembly includes a drying canister, which is fixedly installed at the bottom end of a transfer pipe. A transfer plate is fixedly installed inside the drying canister, and multiple desiccant packets are disposed inside the transfer plate. A breathing tube is fixedly installed at the bottom of the drying canister.

[0008] Preferably, the limiting support assembly includes mounting slots, each mounting slot being formed on the inner wall of the drying tank, and a first spring being fixedly installed inside each mounting slot. A limiting sliding block is fixedly installed on the top of each first spring, and a support plate is fixedly installed on one side of each limiting sliding block.

[0009] Preferably, the detachable component includes a mounting block, which is fixedly mounted on the bottom of the drying tank, a guide rod is fixedly mounted inside the mounting block, and a sealing ring is fixedly mounted on the inner side of the detachable plate.

[0010] Preferably, a second spring is movably sleeved on the outer end of the guide rod, a sleeve is slidably sleeved on the outer end of the guide rod, and a pressing plate is fixedly installed on one side of the sleeve.

[0011] Preferably, the desiccant packets are arranged in a cross pattern inside the drying canister, and the breathing tube extends to a rainproof part such as a support.

[0012] Preferably, the limiting sliding block is slidably connected to the inner wall of the mounting groove, and the two sides of the support plate are respectively movably connected to the desiccant pack.

[0013] Preferably, the two ends of the second spring are fixedly connected to the sleeve and the mounting block respectively, the pressing plate is movably connected to the surface of the disassembly plate, and the disassembly plate extends to the inner wall of the drying tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a drying and protection component, water vapor and salt spray are prevented from entering the bearing housing, which would cause lubricating oil emulsification and prevent bearing and bearing housing rust, thus avoiding damage to the unit. The desiccant pack can effectively absorb moisture and salt in the air. With the support of the limiting support component, the desiccant pack is stably supported, ensuring that it is evenly distributed in the drying tank and continues to play its moisture absorption role. It avoids the protective effect being affected by the accumulation or displacement of the desiccant pack, thereby providing a continuous and stable drying environment for the bearing housing and extending the service life of the bearing housing and internal components.

[0016] 2. By setting up detachable components, the practicality and ease of maintenance of the device are improved. When the desiccant pack reaches saturation, the operator only needs to press the pressing plate to drive the sleeve to slide along the guide rod and compress the second spring, so that the detachment plate can be separated from the inner wall of the drying tank, and then the desiccant pack inside can be easily removed for replacement.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1, Figure 2 , Figure 3 and Figure 5 This utility model provides a technical solution: a bearing housing breathing structure for offshore platforms, including a bearing housing body 1, a breathing port 2 opened on the top of the bearing housing body 1, a transmission pipe 3 fixedly installed on the top of the breathing port 2, and a drying and protection component provided at the bottom end of the transmission pipe 3; a limit support component is provided inside the drying and protection component, a disassembly plate 6 is detachably connected to one side of the drying and protection component, and a detachable component is provided at the outer end of the disassembly plate 6.

[0025] The drying and protection assembly includes a drying tank 41, which is fixedly installed at the bottom of the transfer pipe 3. A transfer plate 42 is fixedly installed inside the drying tank 41, and multiple desiccant packets 43 are disposed inside the transfer plate 42. A breather pipe 44 is fixedly installed at the bottom of the drying tank 41 to prevent rainwater from entering the bearing housing, thereby preventing lubricating oil emulsification and rusting of the bearing and bearing housing. The limiting support assembly includes mounting grooves 51, each of which is formed on the inner wall of the drying tank 41. A first spring 52 is fixedly installed inside each mounting groove 51, and a limiting sliding block 5 is fixedly installed on the top of each first spring 52. 3. A support plate 54 is fixedly installed on one side of the limiting sliding block 53, which can evenly distribute the desiccant pack 43 inside the drying tank 41, preventing the desiccant pack 43 from accumulating and causing poor drying effect in some areas. At the same time, the support plate 54 can provide stable support for the desiccant pack 43, preventing it from being displaced or damaged due to vibration during equipment operation. The desiccant pack 43 is arranged in a cross pattern inside the drying tank 41, and the breathing tube 44 extends to the support and other rainproof parts. The limiting sliding block 53 is limited and slidably connected to the inner wall of the mounting groove 51, and the two sides of the support plate 54 are movably connected to the desiccant pack 43 respectively.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The detachable component includes a mounting block 71, which is fixedly installed at the bottom of the drying tank 41. A guide rod 72 is fixedly installed inside the mounting block 71. A sealing ring 76 is fixedly installed on the inner side of the disassembly plate 6. A second spring 73 is movably sleeved on the outer end of the guide rod 72. A sleeve 74 is slidably sleeved on the outer end of the guide rod 72. A pressing plate 75 is fixedly installed on one side of the sleeve 74. The two ends of the second spring 73 are fixedly connected to the sleeve 74 and the mounting block 71, respectively. The pressing plate 75 is movably connected to the surface of the disassembly plate 6. The disassembly plate 6 extends to the inner wall of the drying tank 41 and fits tightly against the inner wall of the drying tank 41. With the sealing effect of the sealing ring 76, it effectively prevents external water vapor and salt spray from entering the interior of the drying tank 41 after maintenance, ensuring the continuous and efficient operation of the drying protection component.

[0027] Working principle: Air enters the drying tank 41 through the breathing tube 44, is dried by the desiccant pack 43 inside the transfer plate 42, and then enters the bearing housing body 1 through the transfer tube 3 and the breathing port 2, thus balancing the internal pressure of the bearing housing body 1. When the internal pressure of the bearing housing body 1 is higher than that of the outside, the internal air is discharged in the opposite direction through the breathing port 2, the transfer tube 3, the drying tank 41, and the breathing tube 44. During this process, the desiccant pack 43 can absorb water vapor in the air. When the desiccant pack 43 needs to be replaced, the operator can press the pressing plate 75, which drives the sleeve 74 to slide along the guide rod 72 towards the mounting block 71 and compresses the second spring 73, causing the pressing plate 75 to separate from the surface of the disassembly plate 6. Then, the disassembly plate 6 can be pulled out from one side of the drying tank 41. At this time, the limiting sliding block 53 drives the support plate 54 to move upward under the elastic force of the first spring 52. The operator takes out the old desiccant pack 43 and puts in the new desiccant pack 43. The desiccant packs 43 are placed crosswise on the surface of the support plate 54. After the replacement is completed, the disassembly plate 6 is reinserted into the inner wall of the drying tank 41. The pressing plate 75 is released, and the second spring 73 returns to its original deformation, pushing the sleeve 74 and the pressing plate 75 to reset, so that the pressing plate 75 presses the disassembly plate 6, and the sealing ring 76 achieves a seal. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
