The present invention can improve by following scheme:
Described breach is right-angle notch.
Described flabellum body tail end face is provided with an empennage.
Described empennage is tabular, and one end is conical nose, and the other end is square afterbody, conical noseWidth is less than square afterbody, and conical nose is to one side bending of empennage, and conical nose advances towards flabellumDirection.
Described convex tendon extends and connects described cavity along flabellum body length direction.
For achieving the above object, the present invention also can be by the following technical solutions.
A kind of fan blade, has flabellum body, and described flabellum body is strip, flabellum body interiorHave cavity, cavity extends and runs through flabellum body two ends along flabellum body length direction, and its feature existsIn: in described cavity, be provided with some to convex tendon, each described protruding in the upper and lower two sides of flabellum body head positionMuscle is equipped with breach, and each described breach is built into a grasping part that can clamp plate body, flabellum in opposite directionsBody arranges some installation through holes in two walls up and down of described grasping part position, when described fan bladeWhile being installed on fan board, be also provided with safety line in described cavity, safety line one end is fixed on flabellumOn body afterbody, the other end is fixed on described fan board.
The present invention can improve by following scheme:
Described breach is right-angle notch.
Described flabellum body tail end face is provided with an empennage.
Described empennage is tabular, and one end is conical nose, and the other end is square afterbody, conical noseWidth is less than square afterbody, and conical nose is to one side bending of empennage, and conical nose advances towards flabellumDirection.
The present invention adopts described grasping part that the flabellum frame of plate body is clamped, then passes institute by boltState and through hole is installed flabellum is fastened, flabellum is difficult for loosening, and simple in structure, degree of safety is high, andIn the course of work of fan, if the fan blade section of fragmenting into, safety line plays the work of each section of series connectionWith, and be unlikely to directly to fall and cause staff's personal injury in ground from factory building top.

(5) detailed description of the invention
A kind of fan blade as shown in Figures 1 to 7, it has flabellum body 10, described flabellum body10 is strip, and flabellum body 10 inside have cavity 12, and cavity 12 is along flabellum body 10 lengthDirection is extended and is run through flabellum body 10 two ends.
In described cavity 12, be provided with in the flabellum body 10 upper and lower two sides of head position some to convex tendon (14,15), each described convex tendon (14,15) is equipped with breach 14-1, and each described breach is built into one in opposite directionsCan clamp the grasping part 11 of plate body, flabellum body 10 is in two walls up and down of described grasping part 11 positionsFace arranges some installation through hole 10-1. In fact, described every pair of convex tendon (14,15) all can connect andForm a reinforcement to increase the intensity of flabellum, described breach 14-1 can be outside from reinforcement side by oneThe platform extending and reinforcement side form, if reinforcement in Fig. 4 16 is that upper and lower convex tendon connects and forms.So above-mentioned breach 14-1 can be right-angle notch. General fan board has multiple plate bodys, and plate body is stretchedEnter in described cavity 12, plate body, just by described grasping part 11 clampings, is difficult for loosening. As shown in Figure 5,Install while being connected when fan blade and fan board, the installation portion 100 of fan board puts in described grasping part 11In, bolt enters grasping part 11 also through using nut screwing clamping the installation portion of fan board from through hole is installed,Make fan blade be difficult to depart from fan board.
Two walls up and down of cavity 12 are also provided with and strengthen rib 17, on the both sides of offer installation through holeAspect, to increase the intensity of fan body, makes that on the other hand through hole is installed and obtains reinforcement, makes described clamping emptyBetween 11 clampings more compact when fan board.
As shown in Figure 6, described cavity 12 also can be arranged to same as its head one in flabellum body 10 afterbodysThe structure of sample, with an accommodating contiguous block 20, is provided with an empennage 21 on contiguous block 20. Described empennage 21For nestling up the end face of flabellum body 10 afterbodys after tabular installation, described empennage 21 one end are conical headThe 21-1 of portion, the other end is square afterbody 21-2, the width of conical nose 21-1 is less than square afterbody 21-2,Conical nose 21-1 is to one side bending of empennage 21, and conical nose 21-1 is towards the direction of advance of flabellum.At flabellum body 101 afterbodys, empennage 21 is installed, can eliminate fan rotation time, outwards passes airflow obstruction,Reduce energy loss, stablize fan running, raise the efficiency.
In described cavity 12, be also provided with safety line 30, described safety line 30 two ends are fixed on flabellum originallyOn body 10 two ends. In the course of work of fan, if the fan blade section of fragmenting into, this safety line30 play the effect of each section of series connection, and are unlikely to from factory building top directly to fall in ground, cause work peopleMember's personal injury. Certainly,, in the time that described fan blade is installed on fan board, safety line can one endBe fixed on flabellum body afterbody, the other end is fixed on described fan board.
Above-described embodiment is preferred embodiments of the present invention, but embodiments of the present invention are not limited to this,Other are any does not deviate from change, the modification done under Spirit Essence of the present invention and principle, substitute, combination,Simplify, be equivalent substitute mode, within being included in protection scope of the present invention.
