Description

Technical Field

[0001] This utility model relates to the field of vacuum cover technology, specifically to a vacuum cover for injecting adhesive into wind turbine blades. Background Technology

[0002] Wind turbine blades are the core components of wind turbine units that convert natural wind energy into electrical energy. They are also the main basis for measuring the design and technical level of wind turbine units. Vacuum covers are used when applying adhesive to wind turbine blades.

[0003] A vacuum chamber is a type of enclosure that can create and maintain a near-vacuum environment inside. Its basic principle is to remove air molecules from the chamber through various means, such as using a vacuum pump. The vacuum pump continuously extracts gas from the chamber, causing the number of gas molecules inside the chamber to decrease, thereby reducing the air pressure and approaching a vacuum state.

[0004] In existing vacuum covers for wind turbine blade adhesive injection, a large amount of residual adhesive remains on the inner wall of the cover after the adhesive injection is completed. It is difficult for staff to completely clean the residual adhesive on the inner wall of the vacuum cover, which will affect the subsequent use of the vacuum cover. Utility Model Content

[0005] This utility model proposes a vacuum cover for gluing wind turbine blades, which solves the problem that in the prior art, a large amount of residual glue remains on the inner wall of the vacuum cover after use, making it difficult for workers to thoroughly clean this residual glue, which in turn affects the subsequent use of the vacuum cover.

[0006] The technical solution of this utility model is as follows: A vacuum cover for injecting adhesive into wind turbine blades includes a vacuum cover, an exhaust pipe connected to the outer side of the vacuum cover, and also includes columns, a mounting bracket, racks, slide rails, sliding seats, an adjusting mechanism, a hot air chamber, a transmission component, a fan, and a heating assembly. Three columns are mounted on the upper side of the vacuum cover in a ring shape. The mounting bracket is sleeved on the upper part of the outer side of the columns and can rotate on the three columns. Multiple racks are mounted on the lower side of the mounting bracket. Multiple slide rails are mounted on the mounting bracket, and sliding seats are horizontally slidably connected to the slide rails. An adjustment mechanism is installed on the lower side, which moves synchronously with the sliding seat. The hot air chamber is located below the adjustment mechanism via a transmission component, which consists of a connecting plate and two hinged seats. The connecting plate is sleeved on the two hinged seats. Multiple air blowing holes are opened on the inner side of the hot air chamber. When the adjustment mechanism slides synchronously with the sliding seat, it can drive the hot air chamber to move vertically via the transmission component. The fan is connected to the outside of the hot air chamber via an air supply pipe. The input end of the fan is connected to a heating component via the air supply pipe. The heating component is used to heat the air. The outside of the heating component is connected to an air suction hood via the air supply pipe.

[0007] The adjustment mechanism includes a U-shaped frame and a transmission gear. The U-shaped frame is installed on the lower side of the sliding seat. The transmission gear is rotatably installed inside the U-shaped frame via a rotating shaft. The transmission gear meshes with the rack. The U-shaped frame is provided with a driving component for driving the rotating shaft to rotate. The driving component is a forward and reverse rotating motor. The driving component is connected to an external power source via a cable.

[0008] The heating assembly includes a heating chamber, heating tubes, and heating wires. The heating chamber is connected to the input end of the fan through a delivery pipe. Multiple heating tubes are arranged inside the heating chamber, and the heating wires are sleeved on the heating tubes.

[0009] As a preferred embodiment of the vacuum cover for injecting adhesive into wind turbine blades according to this utility model, in order to enable the rotation of the mounting frame, the column is shaped to be wider at the top and narrower at the bottom, and a rotation groove is provided on the lower side of the mounting frame, the width of the rotation groove being adapted to the width of the column.

[0010] As a preferred embodiment of the vacuum cover for injecting adhesive into wind turbine blades according to this utility model, in order to achieve sliding limit of the sliding seat and ensure the stability of the sliding seat during sliding, the slide rail is I-shaped, and multiple slide rails are symmetrically arranged on the mounting frame.

[0011] As a preferred embodiment of the vacuum hood for injecting adhesive into wind turbine blades according to this utility model, in order to limit the movement of the hot air chamber and ensure the stability of the hot air chamber during movement, two limiting rods are installed on the upper side of the hot air chamber, and the limiting rods are inserted into the interior of the mounting frame.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] In this invention, compared to existing vacuum hoods for wind turbine blade adhesive application where a large amount of residual adhesive remains on the inner wall after use, making it difficult for staff to thoroughly clean this residue and affecting the subsequent performance of the vacuum hood, this invention addresses the problem by using a combination of a hot air chamber, a fan, a heating component, and a suction hood to heat and soften the residual adhesive inside the vacuum hood. This softened adhesive then flows to the bottom of the vacuum hood, facilitating cleaning. The combination of a rack, slide rail, sliding seat, adjustment mechanism, and transmission components allows for adjustment of the hot air chamber's blowing height, enabling staff to adjust the height according to their needs and ensuring effective heating of the residual adhesive. Finally, the rotation of the mounting bracket, achieved through the support column and mounting frame, allows for the rotation of the hot air chamber, ensuring comprehensive heating of the residual adhesive inside the vacuum hood and guaranteeing effective cleaning.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this embodiment proposes a vacuum hood for wind turbine blade adhesive injection, including a vacuum hood 1, a column 2, a mounting bracket 3, a rack 4, a slide rail 5, a sliding seat 6, an adjustment mechanism, a hot air chamber 7, a transmission component 8, a fan 9, a heating component, and a suction hood 10. Compared to existing vacuum hoods for wind turbine blade adhesive injection, which often leave a large amount of residual adhesive on their inner walls after use, making it difficult for workers to thoroughly clean this residue and affecting the subsequent performance of the vacuum hood, this embodiment utilizes the cooperation of the hot air chamber 7, the fan 9, the heating component, and the suction hood 10 to heat and soften the residual adhesive inside the vacuum hood 1, thus improving the performance of the vacuum hood. After the residual adhesive in the part is heated and softened, it flows to the bottom of the vacuum chamber 1, which makes it convenient for the staff to clean the residual adhesive inside the vacuum chamber 1. Through the cooperation of rack 4, slide rail 5, sliding seat 6, adjustment mechanism and transmission component 8, the blowing height of hot air chamber 7 can be adjusted, so that the staff can adjust the blowing height of hot air chamber 7 according to the usage needs, ensuring the heating effect of residual adhesive inside vacuum chamber 1. Through the cooperation of column 2 and mounting bracket 3, the rotation of mounting bracket 3 is realized, thereby realizing the rotation of hot air chamber 7, so that hot air chamber 7 can fully heat the residual adhesive inside vacuum chamber 1, ensuring the cleaning effect of residual adhesive inside vacuum chamber 1.

[0024] like Figure 1 and Figure 2 As shown, three columns 2 are installed on the upper side of the vacuum chamber 1, arranged in a ring. A mounting bracket 3 is fitted onto the upper part of the outer side of the columns 2. The cooperation between the columns 2 and the mounting bracket 3 enables the rotation of the hot air chamber 7, allowing it to fully heat the residual adhesive inside the vacuum chamber 1, ensuring effective cleaning. Multiple racks 4 are installed on the lower side of the mounting bracket 3, and multiple slide rails 5 are mounted on the mounting bracket 3. Sliding seats 6 are slidably connected to the slide rails 5, and an adjustment mechanism is installed on the lower side of the sliding seats 6. The hot air chamber 7 is positioned below the adjustment mechanism via a transmission component 8. Multiple air holes are opened on the inner side of the hot air chamber 7, such as... Figure 3As shown, the adjustment mechanism includes a U-shaped frame 101 and a transmission gear 102. The cooperation of the rack 4, slide rail 5, sliding seat 6, adjustment mechanism and transmission component 8 can realize the adjustment of the blowing height of the hot air chamber 7, so that the staff can adjust the blowing height of the hot air chamber 7 according to the usage requirements, and ensure the heating effect of the hot air blown by the hot air chamber 7 on the residual glue inside the vacuum hood 1.

[0025] like Figure 1 As shown, the fan 9 is connected to the outside of the hot air chamber 7 via an air supply pipe. The input end of the fan 9 is connected to a heating element via the air supply pipe, and the outside of the heating element is connected to an air suction hood 10 via the air supply pipe. Figure 4 As shown, the heating assembly includes a heating chamber 201, a heating tube 202, and a heating wire 203. The cooperation of the hot air chamber 7, the fan 9, the heating assembly, and the suction hood 10 can soften the residual adhesive inside the vacuum chamber 1 by heating, thus facilitating the cleaning of the residual adhesive inside the vacuum chamber 1 by the staff.

[0026] Working principle:

[0027] When it is necessary to clean the residual adhesive inside the vacuum chamber 1, the heating tube 202 and heating wire 203 are energized, and they begin to heat. The fan 9 is started, and outside air enters the heating chamber 201 through the suction hood 10 and the air supply pipe. As the air passes through the heating tube 202 and heating wire 203, they heat the air. The heated air then enters the hot air chamber 7 through the fan 9 and the air supply pipe, and is then blown onto the vacuum chamber 1 through the air outlet. The hot air softens the residual adhesive inside the vacuum chamber 1, and the softened adhesive flows to the bottom of the vacuum chamber 1. During the heating process, when it is necessary to rotate the hot air chamber 7, the operator moves the mounting bracket 3, which rotates on the column 2. The mounting bracket 3 rotates, and the hot air chamber 7 rotates via the limit rod. When it is necessary to adjust the blowing height of the hot air chamber 7, the forward and reverse motor is started. The forward and reverse motor drives the rotating shaft to rotate, and the rotating shaft drives the transmission gear 102 to rotate. The transmission gear 102 crawls along the rack 4. During the crawling process, the transmission gear 102 drives the U-shaped frame 101 to move horizontally via the rotating shaft. The U-shaped frame 101 drives the sliding seat 6 to slide along the slide rail 5. The U-shaped frame 101 drives the hot air chamber 7 to move vertically via the transmission component 8, thereby realizing the adjustment of the blowing height of the hot air chamber 7. Because the blowing height of the hot air chamber 7 is adjustable and the hot air chamber 7 can rotate, the residual adhesive inside the vacuum chamber 1 is fully heated and softened. Then, the staff cleans the residual adhesive that has flowed to the bottom of the vacuum chamber 1.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
