Sealing structure of a modular nacelle cover

Abstract

The invention relates to the technical field of nacelle covers, in particular to a sealing structure of a modular nacelle cover, which includes a frame and several nacelle cover modules installed on the frame, and the nacelle cover modules and the frame are connected by bolt assemblies and nuts. A gasket is also provided between the nacelle cover module and the frame, and a sealing structure is provided between adjacent nacelle cover modules, the sealing structure includes a sealing profile and a sealing rubber strip, and the sealing profile is fixed on the frame by rivets. After the nacelle cover module is installed, a water guide groove is formed between the sealing profile, and the sealing strip is located between the sealing profile and the nacelle cover module; the sealing structure of the modularized nacelle cover in the present invention adopts an aluminum alloy sealing profile, and is passed through a rivet Installed on the I-beam skeleton, the contact surface between the profile and the composite board is installed with a sealing strip for waterproofing, and a water guide groove is formed inside the profile, and a double waterproof structure is adopted, which solves the labor-intensive pain point of cutting off the silica gel when replacing parts for traditional nacelle cover seals.

Description

technical field [0001] The invention relates to the technical field of a nacelle cover, in particular to a sealing structure of a modular nacelle cover. Background technique [0002] Carbon peaking in 2030 and carbon neutrality in 2060 will promote the development of new energy and maximize clean energy. Therefore, the new energy industry represented by solar energy, wind energy and ocean energy has developed rapidly. Due to the continuous improvement of wind power technology Innovation and the continued reduction in the cost of generating electricity make it a rapidly growing bitter energy industry. In order to further improve the utilization rate of wind energy and reduce the cost of power generation, it has gradually become a trend to increase the size of wind power generators. [0003] As an integral part of the wind turbine, the nacelle cover plays the role of protecting the main engine and preventing wind. A typical problem of large nacelle covers is that it is diffi...

Problems solved by technology

A typical problem of large nacelle covers is that it is difficult to transport as a whole, so the modular design of large nacelle covers has become a trend

Existing modular photovoltaic nacelle covers often adopt a split or three-piece nacelle structure. Although it can solve the transportation problem, the traditional nacelle cover module and the frame are sealed with silicone. When replacing parts, the removal of the silicone is particularly Time-consuming, and the sealing and waterproof performance of the traditional nacelle cover module needs to be improved
