Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rust-proof packaging technology, and more specifically, relates to a packaging structure for wind turbine generator sets. Background Technology
[0002] With continuous technological advancements in China's wind turbine industry, it has reached a world-leading level. Currently, China's wind turbine market share exceeds 60%, and a large number of Chinese wind turbines are exported, primarily to Europe, America, the Middle East, and North Africa. However, wind turbines are enormous and often require overall hoisting onto cargo ship decks for transport. Traditional packaging methods use waterproof membranes to seal the components, but during hoisting and transshipment, the packaging bags are repeatedly opened, often resulting in corrosion upon arrival at the destination, thus compromising rust prevention. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a packaging structure for wind turbine generator sets, thereby solving the problem that the packaging bags are repeatedly opened during the hoisting and transportation of various components of wind turbine generator sets, often resulting in corrosion of the components after they arrive at their destination.
[0004] To achieve the above objectives, this utility model provides a packaging structure for wind turbine generator sets, comprising:
[0005] The bag body is a heat-shrinkable film. The bag body is used to cover the outside of the wind turbine generator component. The bag body has a first opening at the part corresponding to the mounting surface of the wind turbine generator component. The first opening can accommodate the mounting bracket to pass through.
[0006] The first zipper is a waterproof and sealing zipper, which is located inside the first opening and is sealed to the bag body.
[0007] Optionally, the number of the first zippers is equal to the number of the hanging brackets.
[0008] Optionally, the heat shrink film is a vapor phase rust-preventive heat shrink film.
[0009] Optionally, a rust inhibitor is provided inside the bag.
[0010] Optionally, it also includes a second opening and a second zipper, the second opening forming a personnel entrance / exit, the second zipper being a waterproof and sealing zipper, the second zipper being disposed within the second opening and sealed to the bag body.
[0011] Optionally, it also includes a pearl cotton board, which is disposed inside the bag and wraps around the sharp-shaped corners of the wind turbine components.
[0012] Optionally, a support fixture is provided below the wind turbine generator component, and a third opening is provided at the lower part of the bag body. The third opening is capable of accommodating the support fixture to pass through, and the bag body around the third opening is sealed and bonded to the support fixture.
[0013] Optionally, the bag body includes a bottom sheet and an upper cover, wherein the upper cover is thermally bonded to the bottom sheet.
[0014] This utility model provides a packaging structure for wind turbine generator sets, the advantages of which are as follows: the bag body of the packaging structure for wind turbine generator sets is made of heat-shrink film. After being packaged on the outside of the wind turbine generator set components, it can be heat-shrinked to expel as much air as possible from inside the bag, making the bag body fit the wind turbine generator set components more closely and reducing the burden of rust prevention inside the bag. The bag body is provided with a first opening with a first zipper. The position of the first opening corresponds to the position of the mounting surface of the wind turbine generator set component's hanger, which can accommodate the hanger to pass through. When lifting is required, the first zipper can be opened to facilitate lifting through the hanger. After lifting, the first zipper can be easily closed. Since the first zipper is a waterproof and sealing zipper, closing the first zipper can easily and effectively restore the sealing performance of the bag body, improve its rust prevention effect, and prevent the wind turbine generator set components inside the bag from rusting.
[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0022] like Figure 1 As shown, this utility model provides a packaging structure for wind turbine generator sets, comprising:
[0023] Bag 1, which is a heat shrink film, is used to cover the outside of the wind turbine generator set component. The bag 1 has a first opening at the part corresponding to the mounting surface of the wind turbine generator set component, and the first opening can accommodate the mounting bracket to pass through.
[0024] The first zipper 2 is a waterproof and sealing zipper, which is located inside the first opening and is sealed to the bag body 1.
[0025] Specifically, to address the problem in existing technologies where the packaging bag 1 is repeatedly opened during the hoisting and transportation of wind turbine components, often resulting in corrosion of the components upon arrival at their destination, the packaging bag 1 provided by this utility model for wind turbine components uses heat-shrink film. After being wrapped around the outside of the wind turbine components, it can be heat-shrinked to expel as much air as possible from inside the bag 1, making the bag 1 fit more snugly against the wind turbine components and reducing the burden of rust prevention inside the bag 1. The bag 1 is provided with a first opening having a first zipper 2. The position of the first opening... Corresponding to the mounting surface of the wind turbine generator components, it can accommodate the passage of the lifting seat. When lifting is required, the first zipper 2 is opened to facilitate lifting through the lifting seat. After lifting, the first zipper 2 can be easily closed. Since the first zipper 2 is a waterproof and sealing zipper, closing the first zipper 2 can easily and effectively restore the sealing performance inside the bag body 1, improve its rust prevention effect, and avoid the adverse effects of rust caused by repeated opening of the bag body 1, which makes it difficult to restore the sealing performance of the bag body 1 or requires a long time to restore the sealing performance of the bag body 1. In this way, the wind turbine generator components inside the bag body 1 are prevented from rusting.
[0026] Optionally, the number of first zippers 2 is equal to the number of hanging brackets.
[0027] Specifically, in order to reduce the size of the first opening, each first zipper 2 corresponds to the installation position of a hanging bracket.
[0028] Optionally, the heat shrink film is a vapor phase rust-preventive heat shrink film.
[0029] Specifically, the use of vapor phase rust-preventive heat shrink film not only allows for heat shrinkage but also provides vapor phase rust prevention, thereby improving the rust prevention effect inside the bag body.
[0030] Furthermore, vapor phase rust inhibitor heat shrink film and waterproof sealing zipper can both be purchased directly from external suppliers. Waterproof sealing zipper, also known as waterproof zipper, can prevent water from entering the bag and play a sealing role.
[0031] Optionally, a rust inhibitor is provided inside the bag body 1.
[0032] Specifically, the addition of rust inhibitors can further improve the active rust prevention effect on wind turbine components inside the bag 1.
[0033] Furthermore, rust inhibitors can be rust inhibitor products formed by a mixture of vapor phase corrosion inhibitor and dryer, such as the SF / QV-50 rust inhibitor product from Shenyang Rust Prevention Company. This type of product is a powder rust inhibitor product packaged in a bag.
[0034] In this embodiment, the rust inhibitor is fixed to the inside of the bag body 1 by adhesive to prevent it from falling off.
[0035] Optionally, it also includes a second opening and a second zipper 3, the second opening forming a personnel entrance / exit, the second zipper 3 being a waterproof and sealing zipper, the second zipper 3 being disposed inside the second opening and sealed to the bag body 1.
[0036] Specifically, the second opening and the second zipper 3 provide the bag body 1 with a convenient and quick-to-open and resealable personnel entrance / exit, facilitating personnel entry and reducing the adverse effects of personnel entry and exit on rust prevention.
[0037] Optionally, it also includes a pearl cotton board, which is disposed inside the bag body 1 and wraps around the sharp-shaped corners of the wind turbine components.
[0038] Specifically, pearl cotton sheets are used to wrap the sharp edges and corners of the wind turbine components to provide protection and prevent them from tearing the bag 1.
[0039] Optionally, a support fixture 4 is provided below the wind turbine generator component, and a third opening is provided at the bottom of the bag body 1. The third opening can accommodate the support fixture 4 to pass through, and the bag body 1 around the third opening is sealed and bonded to the support fixture 4.
[0040] Specifically, the support fixture 4 is connected to the bottom of the wind turbine generator component to support the wind turbine generator component, such as a support leg; in order to ensure the sealing and wrapping effect of the wind turbine generator component inside the bag body 1, the lower part of the bag body 1 is provided with a third opening through which the support fixture 4 passes, and the area around the third opening of the bag body 1 is connected to the support fixture 4 by a sealing and adhesive method to ensure the sealing of the bag body 1.
[0041] Optionally, the bag body 1 includes a bottom sheet and an upper cover, the upper cover being thermally bonded to the bottom sheet.
[0042] Specifically, during packaging, a base sheet can be laid out first, and the third opening can be made on the base sheet so that the support fixture 4 can pass through. Then, the upper cover can be used to cover the wind turbine generator components from top to bottom, and the upper cover and the base sheet can be overlapped and thermally bonded together.
[0043] In summary, when using the packaging structure for wind turbine generator sets provided by this utility model, taking the packaging of the wind turbine generator set hub (i.e., the wind turbine generator set component) as an example: First, use pearl cotton board to wrap sharp edges and corners, and fix it with tape to prevent tearing the packaging film; then, lay a bottom sheet under the hub, and expose the support fixture 4 through the third opening, so that the bottom sheet and the support fixture 4 are in direct contact, and the gap at the joint is sealed with heat shrink tape; then, place rust inhibitor at an appropriate position on the hub and fix it to prevent it from falling off; finally, cover the hub from top to bottom with the upper cover, cut off the excess part, and overlap it. First, secure the material at the joints. Then, bond the overlaps using a heat gun or blowtorch. Apply heat to all overlaps, patting them after heating to ensure a firm bond. Next, use a heat gun or blowtorch to heat and shrink the entire surface of the heat-shrink film, carefully controlling the distance and heat to tighten all the heat-shrink film onto the wheel hub surface. Then, install the first zipper 2 and the second zipper 3, making the first and second openings at the mounting surface of the hanging bracket and at the location where personnel enter and exit the wheel hub, respectively. Then, bond the first zipper 2 and the second zipper 3 respectively. Finally, affix or spray-paint a logo or packaging label at an appropriate location on the outer surface of the bag 1 to complete the packaging.
[0044] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
