Description

Engine room frame structure of wind driven generator

Technical Field

The invention relates to the technical field of wind power generation, in particular to an engine room frame structure for a wind driven generator.

Background

The supporting structure of the cabin component of the wind driven generator is an indispensable component in the wind driven generator, supports cabin covers, cabin platforms, an electric control cabinet body, radiators, hydraulic stations, a cabin crane, a current transformer, transformers and other cabin components on one hand, and provides structural support for operation spaces and passages of unit operation and maintenance personnel on the other hand.

At present, the design of the supporting structure of the engine room components of most wind turbine generators does not carry out systematic analysis according to the overall loading characteristics and the supporting requirements of the engine room, but simply designs the connection interface and the supporting requirements in the engine room, so that the supporting structure of the engine room components is excessively heavy or insufficient in supporting capacity, and further the cost is increased or hidden troubles are brought to the safe operation of the generator set. Meanwhile, due to the fact that the whole view is not taken into consideration, designed parts are scattered, and the work of each link of manufacturing, assembling, operation and maintenance is complicated.

Disclosure of Invention

Aiming at the problems, the invention provides a cabin frame structure of a wind driven generator on the basis of comprehensively considering the bearing characteristics of a cabin and the supporting requirements of all parts of the cabin. The scheme of the invention is as follows.

The structure of the invention adopts a modular space frame form and comprises a left module group, a right module group, an upper module group, a lower module group, a rear module group and an auxiliary module group. The left module group, the right module group, the upper module group, the lower module group and the rear module group are respectively positioned at the left part, the right part, the upper part, the lower part and the rear part of the frame structure; the auxiliary module group is an auxiliary connection or support piece of the frame structure. Each module group consists of a plurality of modules; each module group comprises less than 10 modules. Each module is formed by welding or connecting profile steels in a threaded manner, and the module groups are connected in a threaded manner to form an engine room frame structure.

The left module group of the frame structure is connected with the left part of the base; the right module group is connected with the right part of the base; one end of the auxiliary module group is connected with the base or the bearing seat, and the other end of the auxiliary module group is connected with the upper module group. And meanwhile, the frame structure is provided with a corresponding connecting structure for connecting with cabin covers, a cabin platform, an electric control cabinet body, a radiator, a hydraulic station, a cabin crane, a converter, a transformer and other cabin internal parts.

The invention has the beneficial effects that: the cabin component supporting structure of the wind driven generator adopts a modular space frame form, comprehensively considers the cabin bearing characteristics and the supporting requirements of all components of the cabin, reasonably arranges the section steel of each module, improves the assembly efficiency, reduces the field maintenance workload, improves the bearing capacity of the frame structure and reduces the material cost. In addition, the cabin adopting the frame structure can simplify the design of the cabin cover sheet body and reduce the manufacturing, transportation and installation cost of the cabin cover body.
