[0020] The technical solutions in the application embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the application embodiments. In addition, the phrases "in one embodiment" or "in an embodiment" appearing in various places throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics may be combined in one or more embodiments in any suitable manner.

[0021] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the article or terminal device including the elements.

[0022] A wind turbine is an existing new energy power generation device that converts wind energy into electrical energy, including blades installed vertically to the ground, columns supporting the blades, and circuit structures arranged inside the columns. The action of the wind causes the blades to rotate, and the mechanical energy of the rotation is converted into electrical energy through the action of a generator. Due to the influence of the environment or climate, damage may occur to the surface or deeper surface layers of certain parts of the blades. The damaged parts need to be excavated and repaired as soon as possible to avoid affecting the performance of the entire blade. Because the blades or columns are perpendicular to the ground and the installation height is high, the cost of removing the blades for maintenance is high, and the operation process of removal and re-hoisting is complicated. Therefore, it is necessary to repair the blades while they are installed. The existing in-situ repair carrier cannot be installed in any shape, that is, the installation position is limited, and it cannot be repaired in any shape during use. Therefore, this embodiment provides a new in-situ repair carrier, as shown in the following drawings and textual descriptions.

[0023] Please refer to Figure 1 and Figure 2As shown, the utility model provides a frame-covered in-situ carrier for form-fitting clamping, which is a frame-covered structure, including a base, an adsorption bracket 1, an auxiliary bracket 2, a lifting ring, a visual inspection equipment and a force-applying unit. One end of the adsorption bracket 1 is connected to the base, and a multi-directional first suction cup 3 is provided on the base. The auxiliary bracket 2 is arranged between two adjacent adsorption brackets 1 to fix the two adjacent adsorption brackets 1, and a plurality of auxiliary brackets 2 are hinged; the lifting ring is evenly arranged at the top of the adsorption bracket 1; the visual inspection equipment is arranged at the geometric center surrounded by a plurality of adsorption brackets 1, and the force-applying unit presses the first suction cup 3 onto the surface of the part to be repaired; the visual inspection equipment includes a photographing device, a photo processing module and a display module to locate the position of the damaged surface of the part to be repaired and detect the damage parameters.

[0024] The in-situ carrier provided by the utility model is a frame covering structure, such as Figure 1 As shown, the entire frame-covering structure is composed of a base, an adsorption bracket 1, and an auxiliary bracket 2. One end of the base is connected to the adsorption bracket 1 and the other end is sleeved with the first suction cup 3. The auxiliary bracket 2 is connected between the adsorption brackets 1 to stabilize the entire frame structure, and multiple auxiliary brackets 2 are hinged. In addition, hanging rings are evenly arranged at the position of the adsorption bracket 1 at the top of the frame structure to facilitate transfer. Visual inspection equipment and a force-applying unit are arranged in the middle of the frame structure. The visual inspection equipment is arranged at the geometric center surrounded by multiple adsorption brackets 1. The force-applying unit presses down the first suction cup 3 so that the first suction cup 3 is attached to the surface of the part to be repaired. The camera device, the photo processing module, and the display module in the visual inspection equipment are used to locate the position of the damaged surface of the part to be repaired and detect the damage parameters. The in-situ carrier of the frame-covering structure provided by the utility model realizes in-situ auxiliary repair and is compatible with different installation positions, that is, it realizes form-fitting installation and form-fitting repair.

[0025] Specifically, the principle of the in-situ carrier of the frame covering structure in this embodiment to achieve shape-adaptive installation is:

[0026] First, under the covering structure, the entire in-situ carrier is adsorbed and fixed on the surface of the part to be repaired by the first suction cup 3, and the suction cup has strong stability and is easy to remove; second, the multiple auxiliary brackets 2 are hinged, so that the covering structure can be flexibly compatible with multiple installation positions, such as different positions on the rotating blade. In addition, considering that some positions have a certain curvature, the first suction cup 3 also includes an accordion nozzle made of rubber. The deformability and compressibility of the accordion nozzle are used to make the fixed position of the first suction cup 3 not affected by the curvature of the surface of the part to be repaired, that is, the in-situ carrier is installed in a shape-fitting manner, and the application range of the first suction cup 3 is expanded.

[0027] When the in-situ carrier is in use, the size of the entire in-situ carrier is adjusted according to the position and shape of the surface damage of the part to be repaired, and the positions of multiple auxiliary brackets 2 are fixed. Then, it is placed on the surface of the part to be repaired, and the adsorption bracket 1 is pressed so that the first suction cup 3 at the bottom of the adsorption bracket 1 is adsorbed and fixed to the surface of the part to be repaired. Then, the damage parameters of the surface to be repaired (the damage parameters include: damage depth, damage width, damage type, etc.) are detected by visual inspection equipment. The operator can obtain specific detection parameters through the display module, and then select the corresponding excavation tool according to the detection parameters, formulate a repair plan, and prepare repair materials. Finally, with the assistance of the in-situ carrier, the patch is placed in the repair position, and the repair is completed through processes such as layered pressing, heating and curing.

[0028] The aforementioned visual inspection equipment utilizes surface damage visual perception technology. In order not to affect the quality of visual imaging, auxiliary lighting is used and the parameters of the auxiliary lighting are controlled. The visual inspection equipment integrates controllable lighting and deep learning damage recognition methods to accurately detect the damage parameters of damaged parts and improve the quality of repairs.

[0029] In some embodiments, the adsorption bracket 1 and the auxiliary bracket 2 also include a level. The first suction cup 3 includes a rigid shell and a flexible adsorption pad, the flexible adsorption pad protrudes a convex hull of a preset shape relative to the rigid shell, and each convex hull includes a plurality of evenly distributed air holes.

[0030] In this embodiment, the in-place carrier is stably fixed and level with respect to the surface of the part to be repaired, which is a condition to ensure high-quality repair. A level gauge is set between the adsorption and on the auxiliary bracket 2, which can accurately determine the position of the in-place carrier before repair, and is convenient for operators to observe. If it does not meet the preset level requirements, the auxiliary bracket 2 and other structures can be further trimmed. In addition, the convex design of the first suction cup 3 can increase the adsorption force of the first suction cup 3, and the rigid shell can prevent the suction cup of the in-place carrier from being damaged due to excessive external force.

[0031] In some embodiments, the force-applying unit for attaching the first suction cup 3 to the surface of the part to be repaired includes a material-filling auxiliary block, and the force-applying end of the material-filling auxiliary block is ellipsoidal; the surface of the ellipsoidal force-applying end is adsorbed with prepreg. The material-filling auxiliary block is used to apply pressure to the repair material when filling the repair material, so as to increase the hardness and firmness of the filling of the repair material. After the surface of the force-applying end of the ellipsoidal structure is soaked with prepreg, it can avoid sticking to the repair material, or it is convenient to add liquid that is conducive to the repair.

[0032] In some embodiments, a second suction cup is further provided on the side wall of the adsorption bracket 1, and the second suction cup has the same structure as the first suction cup 3. Figure 2 As shown ( Figure 2The middle arrow indicates the stretching direction of the repair platform 4), and also includes the repair platform 4 and a lifting mechanism. The repair platform 4 is in clearance with the part to be repaired and is perpendicular to the installation direction of the part to be repaired. The lifting mechanism includes a bottom plate, a top plate, and a lifting mechanism arranged between the top plate and the bottom plate; the lifting mechanism includes a motor and a telescopic rod, and the motor drives the telescopic rod to extend or shorten.

[0033] The repair platform 4 is used to assist in supporting the in-situ carrier and the repair operator. When repairing a blade, the in-situ carrier is lifted to the repair height by a lifting mechanism, and the blade to be repaired passes through the repair platform 4. The repair platform 4 is lifted or lowered by a traction mechanism composed of a motor and a traction rope. The traction rope is detachably connected to the repair platform 4, and the motor is electrically connected to the fan system. The control device of the fan system controls the motor to work to lift the repair platform 4.

[0034] The aforementioned lifting mechanism may also be a robot arm.

[0035] In some embodiments, the auxiliary bracket 2 between two adjacent adsorption brackets 1 is connected to the adsorption bracket 1 in a quick-release manner. The quick-release connection method can be a lasso connection, or a pin hole and a latch connection. The quick-release connection method adjusts the relative position and angle between each other, thereby increasing the practicality of the in-situ carrier.

[0036] Finally, the utility model provides a frame-covered in-situ carrier for form-fitting clamping. The in-situ carrier is a frame-covered structure, including a base, an adsorption bracket 1, an auxiliary bracket 2, a visual inspection device and a force-applying unit. One end of the adsorption bracket 1 is connected to the base, and a multi-directional first suction cup 3 is provided on the base. The auxiliary bracket 2 is arranged between two adjacent adsorption brackets 1 to fix the two adjacent adsorption brackets 1, and multiple auxiliary brackets 2 are hinged; the visual inspection equipment is arranged at the geometric center surrounded by multiple adsorption brackets 1, and the force-applying unit presses the first suction cup 3 to the surface of the part to be repaired; the visual inspection equipment includes a camera, a photo processing module and a display module to locate the position of the damaged surface of the part to be repaired and detect the damage parameters. The frame-covered in-situ carrier provided by the utility model realizes in-situ auxiliary repair, and is compatible with different installation positions, that is, it realizes form-fitting installation and form-fitting repair.

[0037] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
