Description

TECHNICAL FIELD

[0001] The utility model relates to wind power blade manufacturing technical field especially relates to a wind power blade reinforcing heating device. BACKGROUND

[0002] As one of the core components of wind driven generators, the structural design of wind power blades directly affects the power generation efficiency and safety. The main structure of a wind power blade usually includes an upper shell, a lower shell and a shear beam, wherein the upper shell and the lower shell are combined as a whole through a gluing process. In order to improve the structural safety of the blade, a glass fiber reinforced plastic reinforcing layer is usually used to reinforce the gluing position. The reinforcing layer is generally formed by a hand lay-up process, in which the main raw materials used are resin and glass fiber. These two materials will cross-link under heating conditions to form a composite material with sufficient strength.

[0003] In the common heating mode, there are still problems of large labor cost, material consumption, etc. Therefore, in the wind power blade reinforcing heating device with the application number CN201610168898.2, a deformable heat radiation panel is provided to solve the problems of complicated heating operation, uneven heating, energy waste, etc. However, this technology cannot effectively solve the problem of blade fixation, and when additional fixation equipment is used, the heat radiation panel cannot solve the problem of high temperature affecting the clamping components. In addition, when the other side of the blade needs to be heated, the heat radiation panel is still limited by the turning range, and manual turning of the blade is still required, which increases the waiting time and labor cost, and further reduces the production efficiency. SUMMARY

[0004] The utility model provides a wind power blade reinforcing heating device to solve the above technical problem.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A wind power blade reinforcing heating device, comprising a heating cavity, the both ends of the heating cavity are through and the front surface is provided with an operation port, the inner wall of the heating cavity is provided with at least one group of adjusting guide rails in the circumferential direction, the adjusting guide rail is provided with a heat radiation panel, the bottom of the heating cavity is provided with a bottom support plate, the bottom support plate is provided in the direction of the front surface of the heating cavity, the both sides of the bottom support plate are provided with movable sliding rails, the movable sliding rail is slidably connected with a sliding block, the sliding block is provided with a fixed support, the fixed support is provided with a clamping part for clamping the blade, and the clamping part is rotatably connected with the top end of the fixed support.

[0007] Further, the inner wall of the heating cavity is arc-shaped.

Compared with a flat structure, the arc-shaped design can reduce local heat loss and concentrate heat radiation on the wind turbine blade reinforcement layer, which helps to uniformly heat and cross-link the resin, thereby improving the strength and quality of the reinforcement layer. In addition, the arc-shaped inner wall design can make the heat more evenly cover the blade surface, reduce the risk of local overheating, reduce the thermal stress difference of the blade reinforcement area, avoid material stress concentration or deformation problems caused by temperature difference, thereby improving the structural stability and service life of the blade.

[0008] Further, the adjusting guide rails are provided in three groups, and the three groups of adjusting guide rails are arranged at equal intervals.

The clamping part can be adjusted in height in the vertical direction according to the position and size of the blade, thereby avoiding loosening or deviation of the blade during heating, ensuring the positioning accuracy of the blade and the consistency of the heating effect.

[0011] Further, the clamping part is rotatably connected to the top of the second telescopic end through a rotating shaft, and the axis of the rotating shaft is parallel to the long axis direction of the heating cavity. Since the blade is placed with the long end parallel to the long end of the heating cavity, the blade can be flexibly rotated around the rotating shaft through the rotation of the rotating shaft, so as to uniformly heat the periphery of the blade.

[0012] Further, the heating cavity is provided with a first control unit for controlling the sliding of the heat radiation panel, the bottom support plate is provided with a second control unit for controlling the movement of the sliding block, and the fixed support is provided with a third control unit for controlling the lifting and rotation of the rotating shaft.

[0013] Further, the first control unit, the second control unit and the third control unit are respectively wirelessly connected with an external control device. Through wireless connection, each control unit can be controlled in real time by the external control device, without the need for manual operation near the heating device, thereby improving the operation convenience, especially in a high-temperature environment, which is safer and reduces the protection requirements for the operator.

[0014] In addition, wireless control enables the operator to accurately set and monitor the heating parameters, the sliding block movement position, the lifting of the support and the rotation angle. By adjusting the working state of each control unit through the external control device, the automation degree and positioning accuracy of the heating device are improved, so that the reinforcing area of the blade can be optimally heated.

[0015] Further, the clamping distance of the clamping part is greater than the thickness of the blade. The clamping distance of the clamping part is greater than the thickness of the blade, so that the blade can be stably fixed on the clamping part.

[0016] Further, the bottom support plate is made of stainless steel material. Since the blade needs to be moved out of the heating cavity after heating, at this time the blade is located above the bottom support plate, and the stainless steel material can maintain the stability of the shape and structure during long-term contact with heat energy, thereby prolonging the service life of the support plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The clamping part solves the problem of blade fixation, and since the clamping part is arranged on both sides of the heating cavity, the heat radiation cavity will not be affected by the high temperature generated by the clamping part, so as to ensure the stability of clamping.

[0019] 2. When the other side of the blade needs to be heated, the clamping part is turned over to freely adjust the heating direction and angle of the blade, without human intervention, thereby shortening the waiting time and improving the production efficiency.

[0030] The clamping part 8 is rotatably connected to the top of the second telescopic end 702 through a rotating shaft 9, and the axis of the rotating shaft 9 is parallel to the long axis direction of the heating cavity 1. Specifically, since the blade is placed with the long end parallel to the long end of the heating cavity 1, the blade can be flexibly rotated around the rotating shaft 9 through the rotation of the rotating shaft 9, so as to uniformly heat the periphery of the blade.

[0031] The heating cavity 1 is provided with a first control unit for controlling the sliding of the heat radiation panel 3, the bottom support plate 4 is provided with a second control unit for controlling the movement of the sliding block 6, and the fixed support 7 is provided with a third control unit for controlling the lifting and rotation of the rotating shaft 9.

[0035] The bottom support plate 4 is made of stainless steel material. Specifically, since the blade needs to be moved out of the heating cavity 1 after heating, at this time the blade is located above the bottom support plate 4, and the stainless steel material can maintain the stability of shape and structure when contacting heat energy for a long time, prolonging the service life of the support plate.
