Description

Technical Field

[0001] This utility model relates to a building construction equipment, specifically a glue injection device for splicing mixed wind turbine towers. Background Technology

[0002] During the installation of wind turbine hybrid towers, the joints of prefabricated tower sections require the application of injection bonding adhesive to ensure structural integrity, shear resistance, and sealing. Because the prepared bonding adhesive has a short shelf life, a large number of workers need to be deployed simultaneously to apply and inject the adhesive within a short period, resulting in high labor costs. Furthermore, varying skill levels among workers, coupled with time constraints, can lead to uneven adhesive application and incomplete injection, quality issues that can affect the shear strength of the joints and pose a potential threat to the reliability of the wind turbine hybrid tower throughout its entire lifecycle. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a glue injection device for splicing mixed wind turbine towers, thereby reducing labor costs, improving construction efficiency, and avoiding construction quality problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a glue injection device for splicing wind turbine towers, including a frame and a spiral mixing mechanism and a storage bin mounted on the frame; the inlet of the spiral mixing mechanism is connected to the outlet of the storage bin, and a conveying pipe is detachably connected to the outlet of the spiral mixing mechanism.

[0005] A first valve is installed at the outlet of the delivery pipe;

[0006] The storage silo is equipped with partitions to divide the interior of the storage silo into a first chamber and a second chamber.

[0007] As a limitation of this utility model, the spiral mixing mechanism includes a mixing bin, a spiral agitator rotatably mounted inside the mixing bin, a drive motor mounted outside the mixing bin and whose output end is connected to the spiral agitator, and a battery mounted on the frame and electrically connected to the drive motor.

[0008] As another limitation of this utility model, the storage bin has an inverted conical structure, and a second valve is installed at the discharge port of the storage bin.

[0009] As a further limitation of this utility model, the bottom of the frame is provided with movable wheels.

[0010] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0011] (1) This utility model provides a special equipment for sealing the joint of the prefabricated section of the wind turbine tower. The equipment is simple to operate and easy to use, realizing mechanized construction. Compared with the manual application of splicing adhesive, this utility model has high construction efficiency, low labor cost, and higher construction quality. It can avoid quality problems such as uneven application of splicing adhesive and incomplete injection, thereby ensuring the structural strength, sealing performance and durability of the tower.

[0012] (2) The present invention divides the interior of the storage bin into a first chamber and a second chamber by means of a partition, which can store material A and material B (the splicing adhesive has two components, referred to as material A and material B in the industry) respectively, so that they will only be mixed by the spiral mixing mechanism to form splicing adhesive when used. On the one hand, it can avoid adhesion in the storage bin, and on the other hand, it can ensure the timeliness of the splicing adhesive.

[0013] (3) The storage bin in this utility model is an inverted cone-shaped structure, which can realize the natural flow of materials by gravity.

[0014] (4) In this utility model, the conveying pipe can be detachably connected to the discharge port of the spiral mixing mechanism. In actual construction, the conveying pipe of different diameters can be replaced according to the situation to adjust the injection speed and meet the actual operation requirements.

[0015] In summary, this utility model is suitable for use in the segmented splicing construction of wind turbine towers, and is used to inject splicing adhesive at the joints of prefabricated tower sections. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] This embodiment discloses a glue injection device for splicing mixed wind turbine towers, such as... Figure 1As shown, it includes a frame 1, a spiral mixing mechanism 2 and a storage bin 3 mounted on the frame 1, and a conveying pipe 4 detachably connected to the discharge port of the spiral mixing mechanism 2.

[0022] The frame 1 serves as the supporting structure for all components and is equipped with wheels 5 at the bottom, allowing construction personnel to quickly move this embodiment according to changes in the working environment, work location, and work position.

[0023] The spiral mixing mechanism 2 is used to mix material A and material B in the storage silo 3 into a binding adhesive, and then quantitatively convey it outward through the conveying pipe 4. Figure 1 As shown, the spiral mixing mechanism 2 includes a mixing bin 6, a spiral agitator 7, a drive motor 8, and a battery. The mixing bin 6 is fixed to the frame 1 and has an inlet and an outlet; as shown... Figure 2 As shown, the spiral agitator 7 is rotatably mounted in the mixing bin 6, arranged along the length of the mixing bin 6; the drive motor 8 is mounted on the frame 1, and its power output end is connected to the spiral agitator 7 for transmission. Alternatively, the drive motor 8 can be fixedly mounted on the end of the mixing bin 6, depending on the situation; the battery is fixedly mounted on the frame 1 (not shown in the accompanying drawings in this embodiment), and the battery is electrically connected to the drive motor 8, with a switch button on the connection line. Construction personnel can control the battery to supply power to or disconnect the drive motor 8 using the switch button. When the drive motor 8 starts running, it drives the spiral agitator 7 to rotate, causing the spiral agitator 7 to mix materials A and B entering the mixing bin 6, forming a glue, which is then quantitatively conveyed outwards through the conveying pipe 4.

[0024] Storage silo 3 is used for temporary storage of materials A and B. For example... Figure 1 As shown, the storage silo 3 has an inverted conical structure, and a partition 9 is fixed inside the storage silo 3, dividing the interior of the storage silo 3 into a first chamber and a second chamber. In actual use, material A can be stored in the first chamber and material B in the second chamber, preventing materials A and B from mixing prematurely to form a sticky adhesive. Furthermore, the bottom of the storage silo 3 is a discharge port, which connects to the inlet of the spiral mixing mechanism 2. In this embodiment, the first chamber and the second chamber share the same discharge port, and a second valve is installed at the discharge port to control the feeding of material into the spiral mixing mechanism 2. The second valve is not shown in the accompanying drawings of this embodiment.

[0025] Specifically, the discharge port of storage silo 3 and the inlet of spiral mixing mechanism 2 are sealed together by a quick-release flange, allowing for the removal of storage silo 3 from spiral mixing mechanism 2, enabling construction personnel to periodically clean residual colloids. Depending on actual needs, an arch-breaking device can be installed at the discharge port of storage silo 3 to ensure unobstructed material transport. The arch-breaking device can be a vibrator, pneumatic arch-breaking device, or rotary scraper, as is available in existing technologies.

[0026] The delivery pipe 4 is a flexible hose for discharging the adhesive, and it is detachably connected to the outlet of the spiral mixing mechanism 2. The detachability can be achieved through a snap-fit ​​structure, a quick-connect structure, or a flange connection; in this embodiment, a flange connection is used. A first valve 10 is provided at the outlet of the delivery pipe 4, allowing the construction personnel to control the flow of the pipeline.

[0027] In this embodiment, the construction personnel pour materials A and B into the storage silo 3 according to the mixing ratio of the splicing adhesive; then, the battery is controlled by the switch button to power the drive motor 8, which drives the spiral mixer 7 to rotate; then the second valve is opened, and materials A and B in the storage silo 3 flow into the mixing silo 6 according to the mixing ratio. The materials A and B entering the mixing silo 6 are stirred evenly by the spiral mixer 7 to form the splicing adhesive; the splicing adhesive is pushed into the conveying pipe 4 by the spiral mixer 7, and finally the construction personnel align the adhesive outlet of the conveying pipe 4 with the joint of the precast tower section and open the first valve 10 to inject adhesive into the splicing joint.

[0028] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
