Abstract
A megawatt composite wind power generator blade is characterized in that a root of the blade is arranged with a vertical bolt splicing hole. A lateral part of the blade is arranged with a horizontal nut holding hole, which is vertically through inwards the blade. A nut is positioned into the holding hole and is arranged with a nut element. Wherein, the nut element is arranged with an element to closely match the horizontal nut holding hole and positioned with a nut hole towards the bolt splicing hole. During assembling, a tapped tensile stud is inserted through the bolt splicing hole and connected with the nut element. Therefore, the structure ensures easy operation and high precision compared with an embedded bolt and is a completely mechanical connection. The nut element is horizontally supported by the bolt splicing hole, thus ensuring more solid and stable connection compared with the embedded bolt.
Description
Technical field
The utility model relates to a kind of wind power plant, particularly a kind of megawatt level composite material blade of wind-driven generator.
Background technique
Other homemade MW class blades substantially all adopt the embedded nut structure at present.When making blade, in the layer of the shop of root of blade, imbed threaded metalwork, during assembling to wherein being screwed into bolt and wheel hub links together.This kind Placement misplaces in pre-buried easily, causes the loss that can not save, and only depend on that bonding between metal and the glass fibre reinforced plastics keep being connected firmly, in case as adhesive failure, blade, and the operation of complete machine great danger can appear.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of easy to control, megawatt level composite material blade of wind-driven generator that Placement is stable.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of megawatt level composite material blade of wind-driven generator, be characterized in: it is provided with bolt spliced eye longitudinally at the root of blade, the horizontal nut that has vertical perforation with the bolt spliced eye at the sidepiece of blade in blade is inserted the hole, nut is inserted and is provided with nut member in the hole, described nut member is provided with one and inserts the close-fitting member body in hole with horizontal nut, and member body is provided with nut bore over against the bolt spliced eye.
The utility model compared with prior art, it is provided with the bolt spliced eye and nut is inserted the hole, the bolt spliced eye is inserted vertical perforation the in hole with nut and is constituted T type structure, during assembling, the double end tensile bolt inserts with nut member from the bolt spliced eye and joins, this kind structure is than the easy operation of pre-embedded bolt, precision height; It is a kind of mechanical connection fully, and nut member is laterally carried on a shoulder pole on the bolt spliced eye, so more firm more, stable than pre-embedded bolt.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is the schematic representation of the utility model blade assembling.
Embodiment
A kind of megawatt level composite material blade of wind-driven generator, it is provided with bolt spliced eye 4 longitudinally at the root of blade 2, in blade, have with the horizontal nut of bolt spliced eye 4 vertical perforations at the sidepiece of blade 2 and to insert the hole, nut is inserted and is provided with nut member 3 in the hole, described nut member 3 is provided with one and inserts the close-fitting member body in hole with horizontal nut, and member body is provided with nut bore 1 over against the bolt spliced eye.During assembling, double end tensile bolt 5 inserts with nut member 3 from bolt spliced eye 4 and joins.After blade forming, use special cutting and boring equipment that the surplus capacity of root of blade is cut away, in the root of blade wall thickness, get horizontal nut respectively at the use drill bit then and insert hole and longitudinal bolt spliced eye.During construction, need be with being put on the normal place of blade strictness, and find reference line accurately, can start cutting and boring equipment then and carry out automatic cutting and boring.
