Description

Technical Field

[0001] This invention relates to the field of wind power operation and maintenance technology, specifically to an offshore wind power operation and maintenance lifting and docking device and its usage method. Background Technology

[0002] Currently, offshore wind farm operation and maintenance (O&M) primarily relies on various lifting and docking devices to achieve rapid and safe transfer of personnel and equipment. In the field of offshore wind power O&M, existing lifting and docking devices mainly use single steel cables or simple multi-rope systems for personnel to ascend and descend and for equipment transportation. While these devices meet basic O&M needs to a certain extent, the single steel cable design presents significant safety hazards under the long-term harsh marine environment (such as strong winds, high humidity, and salt spray corrosion). If a single steel cable breaks due to fatigue, corrosion, or accidental damage, it will directly lead to the uncontrolled fall of the O&M platform, seriously threatening the lives of personnel. Due to the harsh environment, single steel cables require frequent inspection and replacement, increasing O&M costs and time. Furthermore, existing systems largely rely on periodic manual inspections to monitor the cable condition, failing to promptly detect and warn of cable wear or surface damage, increasing operational risks. Summary of the Invention

[0023] Beneficial effects:

[0024] (1) This offshore wind power operation and maintenance lifting and docking device uses a first steel cable and a second steel cable to lift the car, ensuring that in the event of an accidental failure of a single steel cable, the other cable can still maintain the stability of the system and avoid falling accidents; at the same time, it facilitates the replacement of one of the steel cables and improves the efficiency of steel cable replacement; the first steel cable and the second steel cable maintain synchronous movement through the same type of winding roller driven by the same reducer, ensuring the smoothness of the lifting process.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-8 This invention provides a technical solution: an offshore wind power operation and maintenance lifting and docking device, including a wind turbine column 1 and a car 2. The surface of the wind turbine column 1 is provided with sliding guide rails 3. The sliding guide rails 3 are arranged in pairs and fixed along the length of the wind turbine column 1. The length of the sliding guide rails 3 is 3-5 meters. The modular design facilitates transportation and installation. Specifically, the sliding guide rail 3 includes a fixed base plate 31. The surface of the fixed base plate 31 is provided with mounting holes, which are used to fix it to the surface of the wind turbine column 1. An L-shaped fixing strip 32 is fixedly connected to the surface of the fixed base plate 31. A pair of L-shaped fixing strips 32 are provided. The components are symmetrically arranged and arranged in a concave structure. A card seat 33 is fixedly connected to one side of the fixed base plate 31, and a steel cable protective cover 34 is provided on one side of the fixed base plate 31. A card block 35 is provided at the bottom of the steel cable protective cover 34. The card block 35 is slidably connected to the card seat 33. A fixing cylinder 36 is fixedly connected to the surface of the L-shaped fixing strip 32 near the side of the steel cable protective cover 34. An insertion rod 37 is fixedly connected to one side of the steel cable protective cover 34. The insertion rod 37 is engaged with the fixing cylinder 36. The steel cable protective cover 34 is fixed through the card block 35 and the insertion rod 37, thus protecting the steel cable.

[0037] Guide wheels 4 are provided at the four corners of the car 2 near the fan column 1. The car 2 is slidably connected to the sliding guide rail 3 through the guide wheels 4. The guide wheel 4 includes a connecting seat 41. A connecting shaft 42 is fixedly connected to one side of the connecting seat 41. Rollers 43 are rotatably connected to both ends of the connecting shaft 42. The diameter of the roller 43 is smaller than the inner height of the L-shaped fixing bar 32 to ensure that the roller can roll. The distance between the two rollers 43 is smaller than the distance between the two L-shaped fixing bars 32 to ensure that the roller 43 can roll within the two L-shaped fixing bars 32. When the car 2 is raised and lowered, the guide wheels 4 on both sides of the bottom are rolled in connection with the surface of the fixed base plate 31, and the guide wheels 4 on both sides of the top are rolled in connection with the inner wall surface of the L-shaped fixing bar 32.

[0038] A crossbeam 5 is fixedly connected to the bottom of the car 2 and to the side near the fan column 1. Fixed pulleys 6 are fixedly connected to both ends of the crossbeam 5. A first take-up roller 7 and a second take-up roller 13 are fixedly connected to the top of the fan column 1. A first steel cable 8 is wound around the surface of the first take-up roller 7. A first fixed seat 9 is fixedly connected to the top of one side of the fan column 1. One end of the first steel cable 8 passes around the two fixed pulleys 6 at both ends of the crossbeam 5 and is fixedly connected to the first fixed seat 9. The rotation of the first take-up roller 7 drives the car 2 to rise and fall. A [missing information - likely a device or structure] is fixedly connected to the center of the top of the car 2 on the side near the fan column 1. The traction pulley 12 and the surface of the second take-up roller 13 are wound with a second steel cable 14. A second fixed seat 15 is fixedly connected to the top of one side of the fan column 1 and at the corresponding position of the second take-up roller 13. One end of the second steel cable 14 passes around the surface of the traction pulley 12 and is fixedly connected to the second fixed seat 15. The rotation of the second take-up roller 13 also drives the car 2 to rise and fall. In order to ensure the smooth rise and fall of the car 2, the first take-up roller 7 and the second take-up roller 13 are of the same model and have the same speed. The double cable design ensures the safety of operation and also makes it easy to replace one of the steel cables.

[0039] A first detection device 10 is fixedly connected to the surface of the wind turbine column 1 and near the top. The first detection device 10 is sleeved on the surface of the first steel cable 8. A control box 11 is set on the top of the wind turbine column 1. The control box 11 is equipped with a comparison module, a control module and an alarm module. The signal output terminal of the first detection device 10 is electrically connected to the comparison module.

[0040] The first detection device 10 includes a rectangular tube 101. A first measuring sensor 102 and a second measuring sensor 103 are installed on the inner wall of the rectangular tube to measure the diameter of the first steel cable 8. The first measuring sensor 102 is positioned below the second measuring sensor 103. The first measuring sensor 102 detects the diameter of the first steel cable 8 in the width direction of the car 2, and the second measuring sensor 103 detects the diameter of the first steel cable 8 in the length direction of the car 2. The vertical design of the detection direction avoids blind spots and improves the monitoring quality. The first measuring sensor 102 and the second measuring sensor 103 transmit the detection results to a comparison module. The comparison module compares the detected value with the original diameter value of the first steel cable 8. If the detected value is inconsistent with the diameter value, the control module triggers an alarm through the alarm module. Perforations 104 are provided at the top and bottom of the rectangular tube 101 to prevent the steel cable from contacting the sensor surface. Specifically, the first measuring sensor 102 can be a through-beam edge measuring sensor receiver, and the second measuring sensor 103 can be a through-beam edge measuring sensor transmitter, using the FASTUS TD1 series. This series uses a light curtain laser, installed facing each other. The transmitter emits a light curtain laser with a width of L1, and the receiver receives two light curtain lasers with widths of L2 and L3 respectively. That is, the diameter of the steel cable is L1-(L2+L3), which is compared with the initial diameter of the steel cable. If it is smaller than the initial diameter, it indicates that the steel cable has worn. If the wear exceeds the threshold, the control module will sound an alarm through the alarm module. The alarm module uses a remote alarm and is directly connected to the wind power control center. If the receiver receives three light curtain lasers of different widths, the steel cable may have broken and forked. In this case, the control module will also sound an alarm through the alarm module.

[0041] The surface of the fan column 1 is equipped with a second detection device 16 for detecting the diameter of the second steel cable 14, and the detection principle is the same as that of the first detection device 10.

[0042] A reducer 16 and a drive motor 17 are fixedly connected to the top of the fan column 1. The reducer 16 is located between the first take-up roller 7 and the second take-up roller 13. The reducer 16 is a dual-output shaft reducer. The two output shaft ends of the reducer 16 are fixedly connected to one end of the first take-up roller 7 and the second take-up roller 13, respectively. The output shaft end of the drive motor 17 is fixedly connected to the input shaft end of the reducer 16. The use of a dual-output shaft reducer ensures that the first take-up roller 7 and the second take-up roller 13 rotate synchronously.

[0043] The car 2 is equipped with a lifting button, which is electrically connected to the control module via a control line. The control terminal of the control module is electrically connected to the drive motor 17. A drag chain 18 is provided on the surface of the fan column 1. One end of the drag chain 18 is fixed to the top of the car 2. The control line is located inside the drag chain 18. The lifting button controls the lifting of the car 2, and the drag chain 18 protects the control line.

[0044] A first directional wheel 19 and a second directional wheel 20 are sequentially arranged on the surface of the wind turbine column 1 and near the top. The first directional wheel 19 is located on one side of the first take-up roller 7 to support the first steel cable 8, and the second directional wheel 20 is located on one side of the second take-up roller 13 to support the second steel cable 14. The direction of the steel cable is changed by the first directional wheel 19 and the second directional wheel 20 to avoid friction between the steel cable and one side of the top of the wind turbine column 1.

[0045] The car 2 has a first door 201 on one side and a second door 202 on the other side for easy entry and exit.

[0046] A method for using an offshore wind power operation and maintenance lifting and docking device includes the following steps:

[0047] S1. Open the first door 201, enter the car 2 and close the door;

[0048] S2. Control the drive motor 17 via the lifting button to raise the car 2;

[0049] S3. After reaching the designated height, the drive motor 17 stops working, the second door 202 is opened, and the fan column 1 is entered to complete the landing.

[0050] In step S2, the measuring sensors in the first detection device 10 and the second detection device 16 transmit the detection results to the comparison module. The comparison module compares the detection value with the original diameter value of the corresponding steel cable. If the detection value is inconsistent with the diameter value, the control module will issue an alarm through the alarm module.
