Abstract
The invention discloses a strengthening and ice melting heating structure for a leading edge shell of a wind power blade. The blade is of a hollow belly structure and is composed of a flow receiving face half block 4 and a flow rejecting face half block 1, and the two half blocks are bonded into a whole in a butt joint mode. A belly cavity is internally provided with a supporting plate P and a supporting plate Q which are longitudinally arranged so that the belly cavity can be isolated into a front edge space A, a middle belly space B and a rear edge space C which are independent from one another. A hot air conveying channel is arranged in the front edge space A, and a supporting plate 6 is further arranged in the front edge space A. The periphery of the supporting plate 6 is connected with the inner wall of the front edge shell in a sticking mode, and a space D is further isolated from the front edge space A. A hot air conveying channel is formed by the space D, and a hot air backflow channel is formed by the rest of the space A except the space D.
Description
Technical field
The invention belongs to technical field of wind power generation, relate to wind wheel blade, specifically, is that a kind of wind electricity blade leading edge housing strengthens and ice-melt heating arrangement.
Background technique
Wind wheel blade is one of the most key parts of wind power generating set, primary structural material is glass fibre reinforced plastics, see Fig. 1, this blade is cancelled structure, limit by technique, be divided into two half blocks form respectively by fluoran stream surface 4, lee side 1, and then docking is bonded as one, there are twice dunnage P, Q in abdominal cavity, abdominal cavity are isolated into 3 separate space A, B, C.Wind wheel is in running, and blade inlet edge constantly bears the alternate load of drawing, pressing, and its intensity is subject to baptism.In order to ensure the bonding strength of two halves housing in leading edge, usual employing structure as shown in Figure 2, namely at the bonding several layers of glass fibre cloth 3 of two halves housing leading edge inwall binder 2, straddle the cemented side seam of two halves housing leading edge, traditionally this structure is called " leading edge case bonding flange ".However, blade inlet edge intensity is still more fragile.
When wind-driven generator runs under cold climate conditions, the leading edge of blade can occur comparatively usually
For serious icing, utilize hot air leading edge, obtained as the effective de-icing method of one and applied.This deicing mode needs to install hot air delivery pipe and reflow pipe in the A of edge space in front of the blade, and Problems existing is: the volume of leading edge space A is large, and the efficiency of heating surface is low, and hot air consumption is large, and the fixing difficulty of Pipe installing.
Summary of the invention
For above problem, the invention provides the enhancing of a kind of wind electricity blade leading edge housing, heating arrangement, both can strengthen the intensity of blade inlet edge housing further, the effect of heating ice-melt can be improved again.
Technical solution of the present invention is:
A kind of wind electricity blade leading edge housing strengthens and ice-melt heating arrangement, this blade is cancelled structure, combined by fluoran stream surface half block 4 and lee side half block 1 and form, two half block docking are bonded as one, dunnage P and the dunnage Q of the longitudinal layout of twice is provided with in abdominal cavity, abdominal cavity being isolated into separate leading edge space A, midfield space B, trailing edge space C, is hot air transfer passage in described leading edge space A; In described leading edge space A, also be provided with dunnage 6, the periphery connection bonding with leading edge inner walls of this dunnage 6, space D is isolated again in the A of leading edge space, this space D forms hot air transfer passage, dunnage 6 is drilled with return port, except the remaining space A of space D forms hot air reflow passage.
Further, be also provided with some stiffening ribs 5 in heating space D, one end of this stiffening rib is bonded in dunnage 6, and the other end is bonded on leading edge housing.
Described dunnage 6 is arcs, and it is convex surface facing leading edge inner walls.
Beneficial effect of the present invention:
Owing to adding dunnage 6 and stiffening rib 5, the structural strength of blade inlet edge housing is significantly promoted, enhances the Security of blade working; Meanwhile, owing to adding dunnage 6, in the A of leading edge space, isolate again heating space D, heating space D volume is little, and heat is concentrated, and make the region temperature rise of blade inlet edge housing icing fast, be beneficial to ice-melt, hot air consumption is few; Hot air delivery pipe, reflow pipe only need be communicated with heating space, backflow space separately, install convenient fixing.
