Description

Technical Field

[0001] This invention relates to the field of ship accessories, specifically to an antenna cleaning device for large floating production storage and offloading vessels. Background Technology

[0002] A floating storage and offloading (FSO) vessel is an oil tanker or barge used to store crude oil during oil extraction in the ocean. It is often connected to a single-point mooring system to form an offshore oil storage system, periodically loading oil onto transport vessels. It can balance the imbalance between continuous oil extraction and bulk oil transportation. It can be specially designed and built, or converted from an old oil tanker or barge. A ship's antenna refers to radar, a device used to radiate and receive electromagnetic waves and determine its detection direction. When emitting, radar must concentrate its energy to the direction it needs to illuminate; when receiving, it should receive echoes only in the direction of detection, while simultaneously determining the target's azimuth and elevation. Antenna performance is more critical for radar equipment than for other electronic devices (such as communication equipment). To ensure the effectiveness of radar, a radome is often installed on the outside of the radar to guarantee the safety of the internal antenna.

[0003] However, when the shroud and radar are connected, water can easily get into the gap between the shroud and radar when the floating oil storage and offloading vessel is operating in a low ambient temperature environment, making it inconvenient for subsequent disassembly and maintenance. Summary of the Invention

[0004] To address the existing problems, this invention provides a large-scale floating production storage and offloading vessel antenna cleaning device, which, when used in conjunction with other devices, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A large floating production storage and offloading (FPSO) vessel antenna cleaning device includes an antenna disk. An upper cover is positioned above the antenna disk. An air guide ring is installed on the outer surface of the upper cover. An inner sleeve is provided on the inner sidewall of the upper cover. A heating wire is installed inside the inner sleeve. A heating power source electrically connected to the heating wire is installed on the upper surface of the inner sleeve. An air pump is installed on the lower surface of the inner sleeve. An air guide pipe is arranged in a ring array on the lower surface of the air guide ring. An air bladder is installed at the lower end of the air guide pipe. A limit block is installed on the inner sidewall of the upper cover. A cover through-slot is formed on the upper surface of the antenna disk. A limit hole is formed on the upper surface of the antenna disk directly below the limit block. A positioning groove is formed inside the antenna disk at the lower end of the limit hole. Drainage holes are arranged in a ring array on the outer sidewall of the antenna disk.

[0007] As a further embodiment of the present invention: a rotating bracket is connected to the lower part of the antenna disk via a rotating shaft, a transmission gear is connected to one side of the rotating bracket at the end of the rotating shaft, and a drive motor is connected to one side of the transmission gear.

[0008] As a further embodiment of the present invention: a turntable is provided below the rotating support, and an elevation support is connected between the turntable and the rotating support.

[0009] As a further embodiment of the present invention: a bottom cover is provided below the turntable, a base mounting plate is installed between the bottom cover and the turntable, and a feed source is installed on the upper surface of the antenna disk.

[0010] As a further embodiment of the present invention: the heating power supply is electrically connected to the heating wire, and the air pump is connected in a through connection to the inner sleeve.

[0011] As a further embodiment of the present invention: the air guide tube is connected to the airbag, the airbag is a rubber component, and the limiting block is engaged with the limiting hole.

[0012] As a further embodiment of the present invention: the antenna disk is rotatably connected to the rotating bracket via the rotating shaft, and one end of the drive motor is equipped with a drive gear located outside the transmission gear.

[0013] As a further embodiment of the present invention: a transmission gear is connected between the elevation support and the turntable.

[0014] As a further embodiment of the present invention, the base mounting plate is rotatably connected to the bottom cover.

[0015] As a further embodiment of the present invention: the air guide ring and the inner sleeve ring are connected in a continuous manner.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By controlling the air pump to pump gas into the inner ring, and using the heating power supply to heat the heating wire, the pumped gas will carry the heat to the inside of the air guide tube. The air guide tube will blow and expand the airbag as a whole, so that the airbag will fill the inside of the dome slot, preventing rainwater from flowing into the connection gap between the antenna disk and the upper dome. At the same time, it can prevent snow from piling up at the connection of the dome in heavy snow.

[0018] 2. The limiting block at the end of the upper cover is pushed into the antenna disk after corresponding to the position of the limiting hole, so that the limiting block enters the positioning groove. Then, by applying torque to the upper cover, the limiting block is misaligned with the position of the limiting hole, so that the upper cover and the antenna disk are installed as a whole. This can ensure the installation of the cover and avoid the situation where the threads corrode and cannot be disassembled properly when using threaded connection methods.

[0019] 3. The control drive motor drives the transmission gear to rotate, which in turn drives the antenna disk to rotate. Under the action of centrifugal force, the water at the connection between the antenna disk and the upper cover is discharged out through the drainage hole.

[0020] 4. When the heating wire is heated by the heat source, the overall temperature of the upper cover will be increased. Therefore, when there is severe weather such as blizzard, the snow will not accumulate on the outside of the upper cover, and the snow will be thrown out by the action of the rotating antenna disk.

[0029] like Figures 1-6As shown, this embodiment provides a large floating production storage and offloading (FPSO) vessel antenna cleaning device, including an antenna disk 4. An upper cover 5 is disposed above the antenna disk 4. An air guide ring 501 is installed on the outer surface of the upper cover 5. An inner sleeve ring 505 is disposed on the inner sidewall of the upper cover 5. The air guide ring 501 and the inner sleeve ring 505 are connected in a through connection. A heating wire 507 is installed inside the inner sleeve ring 505. A heating power supply 508, electrically connected to the heating wire 507, is installed on the upper surface of the inner sleeve ring 505. The heating power supply 508 and... Heating wire 507 is electrically connected. An air pump 506 is installed on the lower surface of the inner sleeve 505, and the air pump 506 is connected to the inner sleeve 505. An air guide tube 502 is installed in a ring array on the lower surface of the air guide ring 501. An air bag 503 is installed at the lower end of the air guide tube 502, and the air guide tube 502 is connected to the air bag 503. A cover groove 402 is opened on the upper surface of the antenna disk 4. The air bag 503 is a rubber component. Gas is pumped into the inner sleeve 505 by controlling the air pump 506, and at the same time, it utilizes... Heating wire 507 is heated by heating power supply 508. The pumped gas will transfer the heat to the inside of the air guide tube 502. The air guide tube 502 will blow and inflate the airbag 503, so that the airbag 503 will fill the inside of the cover groove 402. A limit block 504 is installed on the inner side wall of the upper cover 5. A limit hole 403 is opened on the upper surface of the antenna disk 4 directly below the limit block 504. The lower end of the limit hole 403 is located inside the antenna disk 4 and has a positioning function. The upper cover 5 is positioned so that the limiting block 504 at the end of the upper cover 5 is aligned with the limiting hole 403 and pushed into the antenna disk 4, so that the limiting block 504 enters the interior of the positioning groove 404. Then, by applying torque to the upper cover 5, the limiting block 504 is misaligned with the limiting hole 403, so that the upper cover 5 and the antenna disk 4 are installed as a whole. The limiting block 504 is engaged with the limiting hole 403. The outer wall of the antenna disk 4 has a ring array of drainage holes 401.

[0030] like Figures 2-4As shown, in this embodiment, a rotating bracket 405 is connected to the lower part of the antenna disk 4 via a rotating shaft. The antenna disk 4 is rotatably connected to the rotating bracket 405 via the rotating shaft. A transmission gear 407 is connected to one side of the rotating bracket 405 at the end of the rotating shaft. A drive motor 408 is connected to one side of the transmission gear 407. A drive gear is installed at one end of the drive motor 408 outside the transmission gear 407. By controlling the drive motor 408, the transmission gear 407 is rotated as a whole, so that the rotating shaft connected to the transmission gear 407 drives the antenna disk 4 to rotate as a whole. The water at the connection between the antenna disk 4 and the upper cover 5 is discharged outward through the drainage hole 401. A turntable 3 is provided below the rotating bracket 405. An elevation bracket 406 is connected between the turntable 3 and the rotating bracket 405. A transmission gear is connected between the elevation bracket 406 and the turntable 3. A bottom cover 1 is provided below the turntable 3. A base mounting plate 2 is installed between the bottom cover 1 and the turntable 3. The base mounting plate 2 is rotatably connected to the bottom cover 1. A feed 6 is installed on the upper surface of the antenna disk 4.

[0031] The working principle of this invention is as follows: First, the limiting block 504 at the end of the upper cover 5 is aligned with the position of the limiting hole 403 and pushed into the antenna disk 4, so that the limiting block 504 enters the positioning groove 404. Then, a torque is applied to the upper cover 5 to displace the limiting block 504 from the position of the limiting hole 403, thus completing the overall installation of the upper cover 5 and the antenna disk 4. By controlling the air pump 506 to pump gas into the inner collar 505, the pumped gas will transfer heat to the inside of the air guide tube 502. The air guide tube 502 will blow and inflate the airbag 503, so that the airbag 503 will fill the cover. The interior of the slot 402 reduces the connection gap between the antenna disk 4 and the upper cover 5, preventing rainwater from flowing into the connection gap between the antenna disk 4 and the upper cover 5. At the same time, the heating power supply 508 supplies power to heat the heating wire 507, and the pumped gas will carry the heat to the interior of the air guide tube 502. This also prevents snow from accumulating at the connection of the cover during heavy snow. The control drive motor 408 drives the transmission gear 407 to rotate, so that the shaft connected to the transmission gear 407 drives the antenna disk 4 to rotate, and the water at the connection between the antenna disk 4 and the upper cover 5 is discharged to the outside through the drain hole 401.
