Embodiment Construction

[0017] combine figure 1 , figure 2 with image 3 , the first embodiment of a tower with a truss structure in the present invention includes a tower root 5 connected to the foundation, a tower top 1 connected to the nacelle and rods constituting the truss, and these rods are further divided into thick and vertical Bar 2, thin vertical bar 3, connecting bar 4. The thick vertical bar 2 is made of a steel cylinder, and goes straight from the root of the tower to the top of the tower. Of course, the thick vertical bar 2 and the entire tower will be divided into several short sections and connected together. A ladder equipped with a safety rope 7 is used as a lift for personnel to pass Device 6 is just located at the inside of thick vertical rod 2. The thin vertical rod 3 also passes through the top of the tower from the bottom of the tower like the thick vertical rod 2. It can also be made of a steel cylinder. When its internal space is large enough, a lifting device can also b...

Abstract

The invention discloses a truss-structured tower which is used for wind power generation, and belongs to horizontal-axis wind turbine generators. The truss-structured tower comprises a tower root connected with a foundation, a tower top connected with a cabin, and a lifting device for lifting personnel and equipment. The truss-structured tower is characterized in that a truss structure is composed of rod pieces which comprise a thick vertical rod, and the lifting device is arranged in the thick vertical rod. The truss-structured tower solves the problem that a conventional truss-structured tower has the safety problem of climbing a high tower in the open; and meanwhile, the truss-structured tower has the advantages of light weight, small wind resistance and low tower shadow effect, is detachable in transportation and is convenient for adopting downwind wind wheels, so that the generating cost can be reduced.

Description

technical field [0001] The invention relates to a tower frame of a horizontal-axis wind power generating set for wind power generation. Wind turbines can be divided into large, medium and small wind turbines according to their scale. A truss structure tower in the invention belongs to the towers of large and medium-sized wind power generating sets. According to the structure, the tower frame of the wind power generating set can be divided into two types, the tower frame of the horizontal axis wind generating set and the vertical axis wind generating set. The present invention belongs to the tower frame of the horizontal axis wind generating set. According to the tower structure, it is divided into three types: truss structure, steel cylinder structure and concrete structure. The present invention belongs to the tower frame of truss structure. Background technique [0002] Large and medium-sized horizontal axis wind turbines include a nacelle, a wind wheel, and a tower supp...
