Abstract
The invention discloses a method for carrying out accurate balance weighing of a wind power generator blade, which comprises the following steps of: firstly, hoisting the produced wind power generator blade by using a weighing device, and weighing an overall weight; and secondly, weighing a torque, when the torque is weighed, installing a support frame at the root of the wind power generator blade, selecting any point behind the gravity center of the wind power generator blade as a hoisting point, weighing a toque force in the state that the root section of the wind power generator blade and a horizontal plane are vertical, and then measuring a vertical distance between the hoisting point and the root section of the wind power generator blade. The method disclosed by the invention has the advantages of more simplicity in operation because the wind power generator blade is subjected to balance weighing and the hoisting point can be freely selected, and higher weighing precision.
Description
Technical field
The present invention relates to a kind of Weighing method, relate in particular to a kind of method that the blade of wind-driven generator balance is weighed that is used for.
Background technology
In order to guarantee the even running of aerogenerator; It is basic identical that requirement is installed in the gross weight and the moment of each blade on the aerogenerator; Therefore, just need carry out the balance weighing operation, i.e. the gross weight of weighing blade of wind-driven generator and moment to producing blade of wind-driven generator.Traditional Weighing method is: at first the blade of producing is sling weighing gross weight, weighing moment then with weighing device; During weighing moment, need in advance with the blade twist certain angle, and must confirm the suspension centre of weighing with the tape measuring length of blade; Because the shape of blade of wind-driven generator is more special; The position of suspension centre be difficult to be measured accurately, operates cumbersomely, and the precision of weighing can't guarantee.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of weighing to be used for the method that the blade of wind-driven generator balance is weighed accurately.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: be used for the method that the blade of wind-driven generator balance is weighed, comprise: at first the used for blades of wind driven generator weighing device of producing is sling the weighing gross weight; Weighing moment then; During weighing moment, need bracing frame be installed at the blade root position of blade of wind-driven generator, select after the blade of wind-driven generator center of gravity arbitrarily a bit as suspension centre; Keep weighing torsion under the vertical state at the blade root section that makes blade of wind-driven generator and surface level, measure the vertical range between suspension centre and the blade of wind-driven generator blade root section then.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: the vertical range between suspension centre and the blade of wind-driven generator 1 blade root section is measured through laser range finder.
Advantage of the present invention is: utilize said method that blade of wind-driven generator is carried out balance and weigh, suspension centre can be selected arbitrarily, operates fairly simplely, and the precision of weighing is higher.
Description of drawings
Fig. 1 is the structural representation of blade of wind-driven generator.
Among the figure: 1, blade of wind-driven generator, 2, bracing frame.
Embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, be used for the method that the blade of wind-driven generator balance is weighed, comprising: at first the blade of wind-driven generator of producing 1 usefulness weighing device is sling; The weighing gross weight; The M of weighing moment then during weighing moment M, need install bracing frame 2 at the blade root position of blade of wind-driven generator 1; Select after blade of wind-driven generator 1 center of gravity arbitrarily a bit as suspension centre; Keep weighing torsion F under the vertical state at the blade root section that makes blade of wind-driven generator 1 and surface level, measure the vertical range L between suspension centre and the blade of wind-driven generator 1 blade root section then, thereby calculate moment M=FL.
In order to make measurement more accurate, the vertical range between suspension centre and the blade of wind-driven generator 1 blade root section is measured through laser range finder.
In the concrete weighing process, can carry out repeatedly balance to blade of wind-driven generator 1 and weigh, be generally three times and note down and average.
Utilize said method that blade of wind-driven generator is carried out balance and weigh, suspension centre can be selected arbitrarily, operates fairly simplely, and the precision of weighing is higher.
Claims (2)
1. be used for the method that the blade of wind-driven generator balance is weighed; It is characterized in that: comprising: at first the blade of wind-driven generator of producing (1) is sling with weighing device; The weighing gross weight, weighing moment then is during weighing moment; Need bracing frame (2) be installed at the blade root position of blade of wind-driven generator (1); Select after blade of wind-driven generator (1) center of gravity arbitrarily a bit as suspension centre, weighing torsion under the blade root section that makes blade of wind-driven generator (1) state vertical with the surface level maintenance is measured the vertical range between suspension centre and blade of wind-driven generator (1) the blade root section then.
