An extended wind measuring tower and its installation method

Abstract

The invention relates to the technical field of meteorological observation equipment. The problems that the mounting efficiency of an anemometer tower is low, and mounting workers face dangerous mounting environments when mounting the anemometer tower on an off-shore platform are solved. An extending type anemometer tower comprises at least three tower bodies which are the bottom-layer tower body, the middle-layer tower body and the top-layer tower body correspondingly. The bottom-layer tower body and the middle-layer tower body are each of a triquetral-table truss structure, and the top-layer tower body is of a triangular-pyramid truss structure. The middle-layer tower body is arranged in the bottom-layer tower, and the top-layer tower is arranged in the muddle-layer tower. The extending type anemometer tower further comprises a pulley device and a fixing device, the pulley device comprises a first pulley set, a second pulley set, a third pulley set and a cable set, and the fixing device comprises a first fixing piece and a second fixing piece.

Description

technical field [0001] The invention relates to the technical field of meteorological observation equipment, in particular to an extended wind measuring tower and an installation method thereof. Background technique [0002] At present, all countries in the world are paying great attention to the research and development of sustainable energy. As one of the renewable clean energy, wind energy has great development prospects. [0003] Compared with onshore wind farms, offshore wind farms have greater advantages, such as high development efficiency, low environmental pollution, large wind energy resource reserves, and no occupation of arable land. In order to study offshore wind farms, wind measuring towers are generally arranged on the sea surface. Generally, the following two methods are used to transport the wind measuring towers to the installation site.

Problems solved by technology

In order to study offshore wind farms, wind measuring towers are generally arranged on the sea surface. Generally, the following two methods are used to transport the wind measuring towers to the installation site. One is to install them on land and then transport them to the offshore installation location. However, due to the It is a slender structure with a height of up to 100 meters. It is very troublesome to hoist, install and transport, and the resulting transportation costs are high

The other is to disassemble and transport on the road, then transport to the designated installation location on the sea and assemble it on site. During assembly, the tower at the bottom is generally erected, and then increased layer by layer. The installation of each layer of tower requires separate steps. At the same time, each layer needs to be fixed with side pull cables. However, the installation efficiency is very low when using this method. With the rise of each layer of the tower, the risk factor faced by the installation workers is also increasing. , and each layer needs to be fixed with two cables, which will virtually increase the three-dimensional installation position of the space, and will also bring a certain amount of wind resistance, which will bring safety hazards to the wind measuring tower
