Abstract

The invention relates to a foundation ring of a wind generating set. The foundation ring is characterized in that the foundation ring is uniformly divided into two or more fan-shaped shells along the circumferential direction, the fan-shaped shells are connected together through longitudinal connecting structures, and horizontal connecting structures for being connected with a tower frame of the wind generating set are arranged at the upper parts of the fan-shaped shells. According to the dimensional requirements of transportation, the foundation ring is equally divided into the plurality of fan-shaped shells within the limitation to the transportation size so as to be transported, thus solving the transportation problem caused by the over-sized foundation ring.

Description

A kind of foundation ring of wind generating set
Technical field
The present invention relates to the wind-driven generator field, relate in particular to a kind of foundation ring of wind generating set.
Technical background
In the world wide, in order to utilize to greatest extent limited wind energy resources, land resources, wind-power market requires wind power generating set to high-power, the trend of linear leaf development is more and more urgent, along with wind power generating set power is increasing, this just requires as the critical component----foundation ring that connects wind power generating set and foundation, its diameter is also along with increasing, 5MW foundation ring of wind generating set diameter has reached 6m in the industry, a lot of charge stations have been surpassed, the height of viaduct, the width restriction, this has brought great difficulty to land transportation, and a lot of wind fields must not yield high-power wind turbine unit project because of transportation problem.Along with wind power generating set power further increases, the foundation ring diameter also can be larger.
Summary of the invention
The object of the invention is to overcome above defective, the foundation ring of wind generating set of a kind of convenient transportation, reasonable stress is provided.
Technological scheme of the present invention is: it comprises: foundation ring, described foundation ring along the circumferential direction is evenly divided into two or more than two fan-shaped housing, link together by longitudinal connection structure between fan-shaped housing and the fan-shaped housing, the top of fan-shaped housing is provided with the horizontal connection structure that is connected with wind-power generating unit tower.
For easy for installation, the adpting flange that vertically is provided with of described fan-shaped housing forms a foundation ring chunk, by bolt adpting flange is linked together between the adjacent foundation ring chunk.
In order to satisfy transportation demand, according to the size of foundation ring, described foundation ring is divided into the fan-shaped housing of 180 ° or 120 ° or 90 °.
In order to make the vertical adpting flange reasonable stress after the connection, described fan-shaped housing and point of contact place, fan-shaped casing connecting structure face inside edge should arrange rounded corner.
In order to make the foundation ring after the connection complete, be provided with filler between described fan-shaped housing and the fan-shaped casing connecting structure face.
Effect of the present invention is that the requirement according to transporting size is divided into a plurality of fan-shaped housings in the transportation clearance limit with foundation ring and transports, thereby has solved the transportation problem when the foundation ring size is too large.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that longitudinal connection structure connects the effect schematic representation.
Fig. 3 is the foundation ring cross section view.
Fig. 4 is that longitudinal connection structure connects thin section schematic representation.
Fig. 5 is the foundation ring facade view.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, it comprises, foundation ring 1, foundation ring 1 along the circumferential direction is evenly divided into two fan-shaped housings 2 among the figure, for easy for installation, the two ends that vertically are provided with 4, two foundation ring chunks 4 of adpting flange 3 foundation ring chunks of formation of each fan-shaped housing 2 are joined together to form a complete foundation ring 1 by bolt 6 with adpting flange 3, and the top of foundation ring chunk is provided with the horizontal connection structure 5 that is connected with wind-power generating unit tower.In order to make vertical adpting flange 3 reasonable stress after the connection, described fan-shaped housing 2 should arrange rounded corner 7 with point of contact place, fan-shaped housing 2 linkage structure face inside edge.In order to make the foundation ring 1 after the connection complete, between the surface of contact of foundation ring chunk 4, be provided with filler 8.
After adopting the present invention, owing to can foundation ring 1 be divided into a plurality of fan-shaped housings 2 in the transportation clearance limit transport according to the requirement of transportation to size, thereby solved transportation problem when foundation ring 1 size is too large.
Be not limited only to shown in the embodiment among the present invention, as long as meet the principle of the invention, all in protection scope of the present invention.
