Description

Technical Field

[0001] The present application relates to the technical field of wind turbine towers, and more specifically, to a horizontal-axis offshore wind turbine tower. Background Art

[0002] The development and construction of offshore wind power generation technology can effectively realize the utilization of new energy. The wind energy on the sea surface can be converted into electrical energy through wind turbines. The continuous wind energy on the sea surface plays a vital role in supplementing the increasingly serious power consumption. The tower is the main load-bearing component of the wind turbine. Its main function is to support the mechanical components and power generation system of the wind turbine, and to withstand the force of the wind wheel and the force of the wind on the tower. Therefore, the installation and service life of the tower are particularly important. The existing public technology number CN220566180U proposes a horizontal-axis offshore wind turbine tower. The horizontal-axis offshore wind turbine tower of the device is provided with a fixing ring, a round hole, a threaded groove, a threaded screw, a fixed bearing, a rainproof shell and a limit rod. The rainproof housing is moved by rotating the threaded screw, and the rainproof housing moves to cover the first flange and the second flange. On rainy days, it can effectively prevent rain and prevent rain from corroding the flange connection, effectively extending the service life of the tower body. The structure is simple and easy to use. With respect to the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: the horizontal-axis offshore wind turbine tower in the comparative literature uses a cover to cover the flange bolts. Although it can block rain, the humid air accompanied by salt on the sea surface will also seriously corrode the flange bolts. The tower body is installed in the sea and only relies on three supporting components. It is difficult to limit and float on the sea surface. The stability is low and needs to be improved. In view of this, we propose a horizontal-axis offshore wind turbine tower. Utility Model Content

Although it can block rainwater, the humid air with salt on the sea surface will also seriously corrode the flange bolts. The tower body is installed in the sea, relying only on three support components, it is difficult to limit and float on the sea surface, and the stability is low. The technical problem that needs to be improved and processed is realized, and the bottom tube is fixedly connected to the conical frame, the positioning sleeve cooperates with four pull rods to form a conical structure, and the conical frame is fixedly connected by a floating block and a connecting rod, so that the tower body is stably limited and inserted in the bottom tube and the positioning sleeve, and a plurality of positioning bolts are threadedly installed between the first flange and the second flange to achieve fixation, so that the floating seat is floatingly installed on the sea surface as a whole. In order to stabilize the floating seat, the seabed is connected to the bottom through four positioning mechanisms for limiting processing and floating installation. By installing a protective cover, the first flange, the second flange and the positioning bolts are wrapped and processed to block the contact between the positioning bolts and the air, which can avoid rainwater and isolate the humid air with salt, thereby improving the technical effect of improving the service life of the positioning bolts.
