Embodiment 1

[0017] See figure 1 As well as image 3 : The front edge of the front edge of this wind power and the icing heating structure. This blade is an empty stomach structure, consisting of half -block 4 and back of the back flowing surface, and two half of the docking adhesion.There are two vertical layout supporting the abdominal P and supporting the abdomen Q, which isolate the abdominal cavity into an independent anterior edge space A, the middle abdomen space B, and the posterior edge space C.Essence

[0018] The characteristic of this structure is that in the front edge space A, there is also a support board 6, which is a arc -shaped support board 6, and its convex surface faces the internal wall of the forward edge shell (the shape of the support board 6 can be adjusted according to actual needs to be adjusted according to actual needs.), The surrounding side of the support plate 6 is adhesive to the wall of the front edge shell, and space D is isolated in the front edge space A. T...

Embodiment 2

[0020] See figure 1 As well as Figure 4 , The front edge shell of this wind power blade enhanced and iced heating structure. The blade is an empty stomach structure, consisting of half -block 4 and back of the back flowing surface.There are two vertical layout supporting the abdominal P and supporting the abdomen Q, which isolate the abdominal cavity into an independent anterior edge space A, the middle abdomen space B, and the posterior edge space C.Essence

[0021] In the front edge space A, there is also a support board 6. The support board 6 is an arc, and its convex surface faces the wall of the forward edge shell (the shape of the support board 6 can be adjusted according to actual needs).The surrounding edge of the front edge shell is adhesive to connect, and the hot air conveyor channel D is isolated in the front edge space A. There is a return hole on the support board 6. In addition to the remaining space of the space D, the heat air return channel is constituted.

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 [0001] The present invention is the field of wind power technology. It involves wind wheel leaves. Specifically, it is an anterior edge shell of the wind power blades enhanced and iced heating structure. Background technique [0002] Wind wheel blades are one of the most critical components of the wind turbine. The main structural materials are FRP. See figure 1 This blade is an empty stomach structure, which is limited by craftsmanship. According to the wicked surface 4. The back of the back streaming surface is divided into two and a half pieces, and then the connection is integrated into one.Isolate the abdominal cavity to 3 independent spaces A, B, and C.During the operation of the wind wheel, the front edge of the leaves continues to withstand the transition load of pulling and pressure, and its strength is severely tested.In order to ensure the bonding strength of the two -half shells in the front edge, it is usually used figure 2 The structure shown, that i...
