Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind power generation technology, and in particular to a modular wind turbine blade assembly that can extend and retract vertically. Background Technology
[0002] With the continuous development and popularization of wind power technology, wind turbines have become an important part of the global energy structure transformation. However, the traditional wind turbine blade design has the following main problems: First, under high wind speed conditions, due to the large wind-exposed area of the blades, they are very susceptible to wind impact and damage. Second, the size of traditional wind turbine blades is relatively fixed and inconvenient to increase or decrease, making it impossible to flexibly adjust according to changes in wind speed or other needs, resulting in low power generation efficiency. Utility Model Content
[0003] To address at least one of the above technical problems, this utility model provides a modular wind turbine blade assembly that can extend and retract vertically. The modular design of the blades has an extension function, and the blades can retract into the blade module to facilitate air convection and reduce the wind-receiving area during high wind speed operation, thereby better protecting the wind turbine blades. The modular installation is quick and convenient, and the number of blades can be increased or decreased according to actual needs to improve power generation efficiency.
[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0005] A modular wind turbine blade assembly that extends vertically includes a blade module and a mounting shaft. The blade module consists of an upper module and a lower module. The upper module extends downwards, and the lower module extends upwards. The upper module and the lower module have identical structures, differing only in their mounting directions. The upper module and the lower module are fixedly mounted on the shaft column of the mounting shaft.
[0006] Preferably, the blade module includes a housing, a power housing, blades, blades, and a sandwich layer. The housing is a component of the power housing, which is a cuboid. The blades are two three-dimensional plates disposed at one end of the power housing and flush with the wide surfaces on both sides of the power housing. The sandwich layer is the gap formed between the two blades. The blades extend and slide within the sandwich layer.
[0007] Preferably, the power compartment includes a telescopic device, which includes a telescopic rod; the telescopic device is fixedly connected to the compartment seat, and the telescopic rod is connected to the blade.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses or methods consistent with some aspects of this application as detailed in the appended claims.
[0028] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] like Figures 1-4 As shown, this utility model discloses a modular wind turbine blade assembly with vertical telescopic movement, comprising a blade module 1 and a mounting shaft 2. The blade module 1 consists of an upper module 11 and a lower module 12. The upper module 11 extends downwards, and the lower module 12 extends upwards. The upper module 11 and the lower module 12 have identical structures, differing only in their mounting directions. The upper module 11 and the lower module 12 are fixedly mounted on the shaft column of the mounting shaft 2.
[0030] It is understood that the modular wind turbine blade assembly with vertical telescopic extension of the present invention mainly consists of a blade module 1. The blade module 1 is an integral component in the shape of a rectangle with thickness, and is divided into an upper module 11 and a lower module 12. The upper module 11 extends downwards, and the lower module 12 extends upwards. The upper module 11 and the lower module 12 have the same structure, only the installation direction is different. The upper module 11 and the lower module 12 can be installed and used separately, or they can be combined to form a complete wind turbine blade. They can also be added or removed according to actual needs. The mounting shaft 2 is a cylindrical tube. The blade module 1 is fixed to the tube wall of the mounting shaft 2 to form a wind turbine blade. There are no fewer than three sets of wind turbine blades. The connecting surface between the blade module 1 and the mounting shaft 2 is provided with a fixing plate, or they can be connected and fixed by bolts or welding.
[0031] In a preferred embodiment of this utility model, according to Figure 2 , Figure 3It is known that the blade module 1 includes a housing 110, a power housing 111, blades 112, blades 113, and a sandwich layer 114. The housing 110 is a component of the power housing 111, which is a cuboid. The blades 112 are two three-dimensional plates, which are disposed at one end of the power housing 111 and are flush with the wide surfaces on both sides of the power housing 111. The sandwich layer 114 is the gap formed between the two blades 112. The blades 113 extend and slide inside the sandwich layer 114.
[0032] Specifically, the blade module 1 consists of four parts: a housing 110, a power housing 111, blades 112, blades 113, and a sandwich layer 114. The housing 110 is made of steel plate and is a component of the power housing 111. The power housing 111 is a cuboid with an internal cavity. The blades 112 are two equal-sized three-dimensional plates, which are fixedly mounted at one end of the power housing 111 and flush with the wide surfaces on both sides of the power housing 111. The sandwich layer 114 is the gap formed between the two blades 112. The thickness of the blades 113 is slightly smaller than the gap. The blades 113 slide and extend within the sandwich layer 114.
[0033] In another preferred embodiment of the present invention, the power compartment 111 includes a telescopic device 115, the telescopic device 115 includes a telescopic rod 116; the telescopic device 115 is fixedly connected to the compartment seat 110, and the telescopic rod 116 is connected to the blade 112.
[0034] like Figure 2 , Figure 3 As shown, the power compartment 111 is equipped with the telescopic device 115. There are at least two telescopic devices 115, which are evenly distributed and fixedly connected to the compartment base 110, preferably by bolts. Each telescopic device 115 includes a telescopic rod 116. The telescopic rod 116 is a multi-section telescopic rod, with the foremost section fixedly connected to the blade 112. The telescopic device 115 is controlled by an external wind power monitoring and control system, which can simultaneously control all the telescopic devices 115 to perform telescopic actions.
