Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and
Referring to the drawings this utility model is further described.
Passive charge generator as shown in drawings, including a hollow housing 1, this case top is provided with hole 7；One piezoelectricity group
Part, this piezoelectric element is located at enclosure interior, and it includes multiple piezoelectric ceramic piece 2 enumerated up and down, the superiors' piezoelectric ceramic piece and
Orlop piezoelectric ceramic piece center is consolidated with the first cylindrical electrode 6 and the second cylindrical electrode 3, wherein the first cylindrical electrode 6 respectively
Head stretches out from hole 7；One centrifugal driving assembly, this centrifugal piezoelectric element bottom driving assembly to be located in housing, it is by elasticity
Element 4 and pouring weight 5 form, and the two is longitudinally sequentially connected with.Described flexible member 5 includes spring.
A kind of wind wheel blade, including blade 8, arrester 11 and downlead 9, described downlead 9 is installed in blade 8, institute
State arrester 11 to be installed on blade 8, an arrester 11 at least in parallel on described downlead 9, also include and arrester 11 electricity
The passive charge generator 10 that gas connects, this passive charge generator 10 is aforesaid passive charge generator.Described passive electrical
The first cylindrical electrode 3 in lotus generator is electrically connected with arrester 11.
Passive charge generator 10 described in the utility model is arranged on the inside of wind power blade 8, does not rotate at blade 8
Time pouring weight 5 by flexible member support will not to passive charge generator produce pressure deformation, passive charge generator 10 pushes up
The arrester 9 that portion connects does not produces electric charge；When blade 8 works, pouring weight 5 is forced passive charge generator 10 by centrifugal action
Produce deformation, continue to discharge positive charge to arrester 11, make arrester 11 receive continual and steady positive charge, promote arrester 11
Form upward leader, improve arrester 11 and form the probability of upward leader, the upward leader formed when arrester 11 and thundercloud
When the descending leader formed realizes through, arrester 11 realizes connecing sudden strain of a muscle electric discharge, and conducts lightning current by downlead 9, due to weight
Block 6 end face does not has outside lead so lightning current will not be conducted.
Being described this utility model and embodiment thereof above, this description does not has restricted, shown in accompanying drawing
Be also one of embodiment of the present utility model, actual structure is not limited thereto.If generally speaking this area
Those of ordinary skill is enlightened by it, is creating in the case of objective without departing from this utility model, without creative design with
Frame mode that this technical scheme is similar and embodiment, all should belong to protection domain of the present utility model.
