Simultaneously, the scale of offshore wind farms is expanding, leading to a growing demand for blade inspection and repair technologies. Offshore wind turbine blades are exposed to the harsh marine environment for extended periods, suffering from high humidity, salt spray, strong ultraviolet radiation, rain, and snow, making them susceptible to varying degrees of corrosion and wear. This damage not only affects the power generation efficiency of wind turbines but can also, in severe cases, lead to blade breakage, endangering the safety of the turbines and causing major safety accidents. Therefore, regular inspection and maintenance of offshore wind turbine blades is of paramount importance.
[0003] Offshore wind turbine blade inspection and repair is a high-risk job. Workers need to operate in dangerous environments such as high altitudes and offshore, which increases the risk of safety accidents. In the event of severe weather such as strong winds, the consequences would be unimaginable. Furthermore, due to the large size of offshore wind turbine blades, maintenance personnel in current technologies must change their height and position during maintenance, which increases safety hazards, reduces work efficiency, and complicates the maintenance process.

Two inspection platforms are provided, each equipped with inspection equipment. The inspection platforms are located on the left and right sides of the fixed frame and connected to it via a movable frame. A vertical sliding groove is provided at the connection between the inspection platform and the movable frame, and a horizontal sliding groove is provided at the connection between the fixed frame and the movable frame. A motion motor is installed inside the fixed frame and controlled by a control system. The inspection platforms and the fixed frame have vertical and horizontal degrees of freedom of movement, respectively. The inspection platforms located on both sides of the fixed frame can be merged towards the center, with the blade to be repaired located between the two inspection platforms.
[0006] Preferably, the upper surface of the detection platform is provided with an opening. When two detection platforms are combined, the openings combine to form a placement groove, and the blade to be repaired is placed inside the placement groove.

[0013] 1. This offshore wind turbine blade inspection and repair personnel operating platform device, through the cooperation of a moving frame and vertical and horizontal slideways, enables flexible movement of the inspection platform in both vertical and horizontal directions. In actual operation, the blade requiring repair is first adjusted to its lowest position using a specific rotation mechanism to facilitate operation and repair work. Then, the operator uses a sophisticated control system to manipulate the moving frame, driving the inspection platform carrying the professional repair personnel to slowly move to a position directly above or to the side of the target blade for precise alignment, thus fully preparing for subsequent repair work. To improve operational efficiency and ensure... To ensure personnel safety, a sturdy and transparent windshield has been added to the outer surface of the inspection platform. This windshield not only provides operators with a clear view, allowing them to directly observe the relative position between the inspection platform and the blades and ensure accurate movement, but also creates a solid protective barrier for the maintenance personnel working diligently on the platform.

[0021] 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.
[0022] Please see Figures 1-5A personnel operating platform device for inspecting and repairing offshore wind turbine blades includes an inspection platform 1 and a fixed frame 2. Two inspection platforms 1 are installed inside each, with inspection equipment mounted on them. The inspection platforms 1 are located on the left and right sides of the fixed frame 2, respectively, achieving symmetrical installation. They are connected to the fixed frame 2 via a movable frame 3. A vertical slide groove 11 is provided at the connection between the inspection platform 1 and the movable frame 3, and a horizontal slide groove 21 is provided at the connection between the fixed frame 2 and the movable frame 3. These two mechanisms work together, using the movable frame 3 to allow the inspection platform 1 to move in both horizontal and vertical directions, facilitating the adjustment of the relative position between the repair personnel and the blade to be repaired. The fixed frame 2 contains a motion motor, controlled by a control system, which provides vertical and horizontal degrees of freedom of movement on both the inspection platform 1 and the fixed frame 2. Under the control of the control system, the motion motor can precisely move and lock on the slide grooves. This mechanism is existing technology and will not be described in detail here. The inspection platforms 1 located on both sides of the fixed frame 2 can be merged towards the middle, with the blade to be repaired located between the two inspection platforms 1.
[0023] In this example, please refer to Figures 1-2 The testing platform 1 is equipped with windshields 5 on the outer surfaces of both sides of the fixed frame 2. The upper and lower surfaces of the testing platform 1 are provided with openings. When the two testing platforms 1 are combined, the openings form a placement groove 12. The blade to be repaired is placed inside the placement groove 12, which makes it convenient for repair personnel to repair both sides of the blade to be repaired at the same time, and also isolates the impact of bad weather on the repair.
[0024] Please see Figures 1-3 The testing platform 1 has a multi-story structure, with repair tools placed on each floor. Each floor is connected by stairs 4, which facilitates the movement of repair personnel and the repair of blades at different heights. The width of the testing platform 1 is greater than the widest part of a single blade to be repaired, so that the testing platform 1 can completely cover the blade.
[0025] Please see Figures 2-3 A base 6 is fixedly connected to the bottom of the fixed frame 2. Reinforcing ribs 61 are provided on both sides of the base 6. A staircase 4 is provided between the base 6 and the ground and the fixed frame 2. An electromagnetic locking structure 31 is provided on the adjacent side of the two movable frames 3. The electromagnetic locking structure 31 is a locking structure composed of electromagnets. When the electromagnetic locking structure 31 is energized, the electromagnets are energized and generate magnetic attraction, and the two movable frames 3 are connected. When the power is off, the magnetic attraction disappears, and the two movable frames 3 regain their degrees of freedom of movement, so as to ensure the stability of the operating platform and prevent accidental movement.
[0026] In actual operation, the blade to be repaired is first adjusted to its lowest position using a specific rotation mechanism to facilitate operation and repair work. Next, operators use a sophisticated control system to manipulate the moving frame 3, driving the inspection platform 1, carrying professional repair personnel, to slowly move to a position directly above or to the side of the target blade for precise alignment, thus preparing for subsequent repair work. To improve operational efficiency and ensure personnel safety, a sturdy and transparent windshield 5 is specially added to the outer surface of the inspection platform 1. This windshield 5 not only provides operators with a clear view, allowing them to directly observe the relative position between the inspection platform 1 and the blade, ensuring accurate movement, but also creates a solid protective barrier for the repair personnel working diligently on the platform. It effectively isolates them from the harsh weather conditions commonly found in offshore wind farms, such as strong winds, heavy rain, and wave splash, creating a relatively stable and safe working environment for the repair team and greatly reducing the potential threats of external factors to the progress of the operation and the safety of personnel.
[0027] In summary, this offshore wind turbine blade inspection and repair personnel operation platform device is designed with two symmetrically installed inspection platforms 1, and placement slots 12 are opened on the upper and lower surfaces of the adjacent ends of the two inspection platforms 1, allowing the blade to pass through. In use, the two inspection platforms 1 are brought together under the control of the moving frame 3, covering the front and rear sides of the blade to be repaired. While repairing both sides at the same time, it isolates the interference of external weather conditions and facilitates the vertical movement of the moving frame 3, achieving the purpose of repairing blades at high positions. Compared with the existing technology, it greatly increases work efficiency and construction safety.
