[0002] Wind turbine blade moulds are basic components used in the preparation and forming of wind turbine blades. First, the wind turbine blade mould is clamped and positioned before use. For the preparation of the same wind turbine blade, the wind turbine blade mould is divided into two parts, and the hot-melt materials for wind turbine blade preparation are hoisted and poured using lifting equipment. After the upper and lower moulds have respectively completed half of the forming process of the wind turbine blade, the upper and lower moulds and the corresponding wind turbine blades are docked and assembled to achieve the initial forming of the wind turbine blade.

[0003] Due to its large size and constant overall size, the wind turbine blade mold needs to be equipped with a corresponding clamping mechanism, that is, a base structure for mold shaping, etc., when it is used. At the same time, since the wind turbine blade is formed in the mold, in order to facilitate the overall demoulding of the wind turbine blade and prevent it from being partially damaged during the demoulding process due to local adhesion and adsorption tension, some wind turbine blade molds will also be equipped with a demoulding structure during preparation and use. The demoulding structure is further positioned by the clamping mechanism, so that when the wind turbine blade mold is demoulded later, the demoulding structure can be driven by the clamping mechanism to achieve rapid demoulding application; Then, when the existing clamping mechanism drives the demoulding structure to separate the wind turbine blade from the mold, the general method used is to use vibration to achieve the separation between the wind turbine blade and the mold through vibration conduction. However, in actual use, due to the large volume of the wind turbine blade and the mold, only vibration is used to separate the two. The external vibration force weakens quickly during the conduction process, the wind turbine blade and the mold are separated slowly, and there are many residual adhesion positions after separation, which makes it difficult to adjust the application range and frequency of the demoulding structure drive work.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original wind turbine blade mold clamping mechanism. Summary of the invention

[0013] Preferably, the elastic airbag is arranged in a strip-shaped structure, and two ends of the elastic airbag are respectively fixedly connected to the inside of the cover body support and the annular structure of the airbag ring.

[0014] Preferably, a photoelectric sensor is disposed in the middle of the cover body bracket and the middle of the mounting bracket, and the two photoelectric sensors are distributed correspondingly, and an exhaust port is also disposed in the middle of the cover body bracket.

[0015] Furthermore, the present invention also discloses a clamping method of a wind turbine blade mold clamping mechanism, and the specific method is as follows: S1: First, the blade mold body is supported by a positioning clamping support, the positioning clamping support is composed of a pipe-type truss structure, and bolts are used to clamp and install the blade mold body; S2: Secondly, auxiliary positioning blocks embedded and installed at equal intervals are arranged on the blade mold body to form a complete mold structure, and the auxiliary positioning blocks are positioned by mounting brackets, telescopic rods and positioning brackets to prevent the auxiliary positioning blocks from loosening during the molding and manufacturing of the wind turbine blades; S3: An airflow conveying component and an airflow vibrator are set at the same time.

When the demoulding is applied, the high-temperature airflow can shrink the elastic member inside the telescopic rod and separate the auxiliary positioning block from the positioning bracket, release the positioning state of the auxiliary positioning block, and make the auxiliary positioning block swing and vibrate under the action of the airflow, and discharge the airflow to achieve the rapid demoulding of the wind turbine blade; Furthermore, the inverted truncated cone structure of the positioning bracket is set, when the positioning bracket releases the limiting state of the auxiliary positioning block, the auxiliary positioning block can swing and vibrate along the rotating axis node installed by the telescopic rod, which will not affect the vibration demoulding use of the auxiliary positioning block. At the same time, the elastic member itself also has an elastic effect, which improves the vibration demoulding efficiency of the auxiliary positioning block. 2. By setting the guide sliding rod and the cover body bracket, the multi-directional solenoid valve discharges airflow in different directions, and utilizing the reverse thrust force of the airflow discharge, the cover body bracket and the airbag ring and other components thereon are moved, and the guide sliding rod and the cover body bracket are used for sliding and magnetic positioning to achieve the positioning of the cover body bracket and the exhaust structure thereon, and realize the directional discharge of pressurized gas.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 4 The present invention provides a technical solution: a wind turbine blade mold clamping mechanism with an adjustable adaptation range, comprising: a blade mold body 1, which is fixedly mounted on the top of a positioning clamping support 2 by bolts, and an outer positioning cavity 3 is also fixed on the bottom side wall of the blade mold body 1; In the present technical solution, the positioning of the blade mold body 1 is achieved by utilizing the positioning clamping support 2 and the action of bolts. Due to the production and manufacturing size requirements of wind turbine blades, their overall size is constant, so the length and size of the blade mold body 1 are also synchronously constant. The positioning clamping support 2 is provided to achieve the positioning and assembly of the blade mold body 1, which is convenient for the subsequent docking and assembly of the formed wind turbine blades.

[0021] It also includes: an auxiliary positioning block 4, which is embedded and installed on the inner side wall of the blade mold body 1 at equal intervals, and a mounting bracket 5 and a positioning bracket 7 are fixed in the outer positioning cavity 3 directly below the auxiliary positioning block 4, and a telescopic rod 6 is rotatably connected in the mounting bracket 5, and the end of the output shaft of the telescopic rod 6 is fixed to the center of the back of the auxiliary positioning block 4, and the positioning bracket 7 and the back of the auxiliary positioning block 4 are penetrated; an elastic member 8 is arranged in the telescopic rod 6, and an air flow vibrator 601 is arranged on the outer side wall of the telescopic rod 6, and an air flow vibrator 601 is also arranged in the outer positioning cavity 3. The airflow conveying component drives the auxiliary positioning block 4 to vibrate and exhaust; the outer side of the auxiliary positioning block 4 and the inner side of the blade mold body 1 are both set as curved surface structures, and the two curved surface structures are set in the same plane, and the auxiliary positioning block 4 is coaxially fixed with the telescopic rod 6, and the telescopic rod 6 is connected with the mounting bracket 5 through the central axis and the bearing to form a relative rotation structure; the mounting bracket 5 is set in a "U"-shaped structure, and the middle part of the "U" shape of the mounting bracket 5 is parallel to the bottom of the telescopic rod 6, and a spacing is reserved, and the two are magnetically adsorbed and positioned; In the above technical solution, the auxiliary positioning block 4 belongs to the demoulding application mechanism used in the present mold, and forms a complete wind turbine blade manufacturing mold with the blade mold body 1. At the same time, the installation of the auxiliary positioning block 4 requires clamping and positioning due to the need to realize subsequent demoulding. The auxiliary positioning block 4 is installed and limited by the clamping and positioning mechanism to prevent the deviation of the wind turbine blade preparation molding due to loosening during use. The clamping mechanism includes auxiliary positioning components such as a telescopic rod 6 and a positioning bracket 7. The telescopic rod 6 and its internal elastic member 8 are used to realize the reverse push of the auxiliary positioning block 4. Limiting, under the penetration action of the positioning bracket 7 and the auxiliary positioning block 4, the auxiliary positioning block 4 is stably positioned and will not loosen. At the same time, the use of airflow conveying components can be utilized. Under the action of airflow, the telescopic rod 6 can be telescoped and shaken, and the limited state of the auxiliary positioning block 4 can be released, so that it can oscillate with different amplitudes due to the change in the size of wind airflow. The telescopic rod 6 and the mounting bracket 5 are relatively flipped due to vibration, so that the auxiliary positioning block 4 is separated from the formed wind turbine blade, and pressurized airflow is introduced at the position where the two are separated to achieve rapid separation between the wind turbine blade and the mold.

[0022] In the above technical scheme, it is further disclosed that the positioning bracket 7 and the auxiliary positioning block 4 are telescopically movable through-mounted, and the end of the positioning bracket 7 located on the curved surface side of the auxiliary positioning block 4 is an inverted truncated cone structure, and the inverted truncated cone end of the positioning bracket 7 is fitted and connected with the curved surface side wall of the auxiliary positioning block 4; by adopting this technical scheme, when the auxiliary positioning block 4 is clamped due to positioning by the clamping mechanism, it is directly limited by the positioning bracket 7, and when the auxiliary positioning block 4 moves downward due to the contraction of the telescopic rod 6, the auxiliary positioning block 4 is directly contacted by the positioning bracket 7 in a limited state, and at the same time, it will not affect the shaking of the auxiliary positioning block 4, which is driven by the extension and contraction of the telescopic rod 6 caused by the airflow and the relative flipping action between the telescopic rod 6 and the mounting bracket 5.

[0023] At the same time, in this embodiment, a clamping method of the wind turbine blade mold clamping mechanism is also disclosed, and the specific method is as follows: S1: First, the blade mold body 1 is supported by the positioning clamping support 2. The positioning clamping support 2 is normally composed of a pipe-type truss structure, and bolts are used to clamp and install the blade mold body 1; S2: Secondly, auxiliary positioning blocks 4 are embedded and installed at equal intervals on the blade mold body 1 to form a complete mold structure, and the auxiliary positioning blocks 4 are positioned by the mounting bracket 5, the telescopic rod 6 and the positioning bracket 7 to prevent the auxiliary positioning blocks 4 from loosening during the molding and manufacturing of the wind turbine blade; S3: An airflow conveying component and an airflow vibrator 601 are set at the same time. When the pressurized airflow is introduced, the telescopic rod 6 vibrates at a high frequency under the vibration and elastic action of the elastic member 8, and the positioning and flip-type shaking of the auxiliary positioning block 4 are adjusted to release the positioning and clamping state of the auxiliary positioning block 4, thereby realizing the demolding of the formed wind turbine blade on the blade mold body 1.

[0024] Embodiment 2: Based on Embodiment 1, the present invention further discloses a method and technical solution for how the clamping mechanism can realize the rapid separation of the mold and the wind turbine blade through the position of the auxiliary positioning block 4, and the specific contents are as follows: The telescopic rod 6 is hollowed out, and the interior of the telescopic rod 6 is connected with the interior of the outer positioning cavity 3 through the hollow hole, and there is a difference in the metal material and thermal expansion coefficient between the inner and outer sides of the spiral of the elastic member 8 inside the telescopic rod 6; in this technical scheme, an elastic member 8 of different materials is firstly arranged. Due to the difference in thermal expansion coefficients of metals, when the pressurized and high-temperature airflow is introduced into the outer positioning cavity 3 through the airflow conveying component, due to the hollowing out of the telescopic rod 6, the airflow can directly cause the elastic member 8 to deform and shrink, so that the contraction of the telescopic rod 6 drives the auxiliary positioning block 4 to move and change its position. At the same time, in order to improve the thermal contraction efficiency of the elastic member 8, it can be made of a memory metal with high heat sensitivity; at the same time, the difference in gas flow rate introduced by the airflow conveying component can achieve the shaking of the telescopic rod 6 due to the elastic reaction force of the elastic member 8 itself under the impact of airflows of different speeds.

[0025] The airflow conveying component includes a guide threaded tube 12 movably installed on the outer wall of the positioning cavity 3; at the same time, a guide sliding rod 9 is fixedly arranged on the inner side of the outer positioning cavity 3 along its coaxial direction, and a cover body bracket 10 is slidably installed on the outer side of the guide sliding rod 9, and a multi-directional electromagnetic valve 11 is fixed at the bottom of the cover body bracket 10, and the multi-directional electromagnetic valve 11 is connected with the guide threaded tube 12, and exhaust holes are arranged on the left and right sides of the multi-directional electromagnetic valve 11, and the exhaust holes are oriented in the same direction as the guide sliding rod 9; the outer side of the guide sliding rod 9 is arranged in a rectangular structure, and the rectangular outer wall of the guide sliding rod 9 and the cover body bracket 10 are radially engaged and axially fitted. The sliding connection, and the two are weakly magnetically adsorbed and positioned; the cover body bracket 10 is movable An airbag ring 13 is installed, a film is arranged between the airbag ring 13 and the outer side of the cover body bracket 10, and the connection between the airbag ring 13 and the cover body bracket 10 is arranged as an annular structure, an elastic airbag 14 is arranged in the cover body bracket 10, and the airbag ring 13 and the elastic airbag 14, the cover body bracket 10 and the multi-directional solenoid valve 11 and the guide threaded tube 12 are sequentially connected; the elastic airbag 14 is arranged in a strip structure, and the two ends of the elastic airbag 14 are respectively connected to the inside of the cover body bracket 10 and the annular structure of the airbag ring 13 in a through-connected fixed connection; the middle part of the cover body bracket 10 and the middle part of the mounting bracket 5 are both provided with photoelectric sensors 15, and the two photoelectric sensors 15 are arranged correspondingly, and the middle part of the cover body bracket 10 is also provided with an exhaust port; In the above technical scheme, since the outer positioning cavity 3 corresponds to a plurality of auxiliary positioning blocks 4, in order to improve the stability and efficiency of the airflow introduced into the airflow conveying component, the airflow can be accurately aligned with the auxiliary positioning block 4 required for demolding according to the use needs. By adopting this technical scheme, firstly, an external computer numerical control device is used to control the exhaust of the corresponding exhaust hole on the multi-directional solenoid valve 11. Under the reverse thrust of the gas, the cover body bracket 10 is moved axially along the guide sliding rod 9 to change the positioning of the cover body bracket 10. At the same time, the signal transmission of the photoelectric sensor 15 is utilized. When the photoelectric sensor 15 in the middle of the cover body bracket 10 is coaxially corresponding to the photoelectric sensor 15 in the middle of the mounting bracket 5 of the corresponding auxiliary positioning block 4, the photoelectric sensor 15 receives the photoelectric signal and transmits it to the external computer numerical control device, which is convenient for artificial control of the positioning state of the cover body bracket 10, and The gas is again introduced into the cover body bracket 10 and the airbag ring 13 through the multi-directional solenoid valve 11 through the guide threaded tube 12, so that the airbag ring 13 moves and expands, and the airbag ring 13 and the film connected thereto are used to wrap the corresponding back side of the auxiliary positioning block 4 and the clamping mechanism on the back side, so that the airflow discharged from the exhaust port in the middle of the cover body bracket 10 is directly introduced into the auxiliary positioning block 4, reducing the airflow escape, and making the back structure of the auxiliary positioning block 4 receive the airflow impact more stably, realizing the contraction of the telescopic rod 6 and the positioning movement and shaking of the auxiliary positioning block 4, and at the same time, an airflow vibrator 601 is also arranged on the outside of the auxiliary positioning block 4, so that the shaking frequency and range of the auxiliary positioning block 4 are directly regulated by the airflow, so as to realize the demoulding of the wind turbine blade, and at the same time, most of the airflow is introduced into the contact surface between the mold and the wind turbine blade through the gap between the auxiliary positioning blocks 4, so as to improve the demoulding efficiency of the wind turbine blade.
