Problems solved by technology
The traditional weighing method is: first lift the produced blades with a weighing device, weigh the total weight, and then measure the moment. When measuring the moment, the blade needs to be twisted to a certain angle in advance, and the length of the blade must be measured with a tape measure. Determine the weighing lifting point. Due to the special shape of the wind turbine blades, it is difficult to measure the position of the lifting point accurately, the operation is cumbersome, and the weighing accuracy cannot be guaranteed

Embodiment Construction
[0009] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0010] Such as figure 1 As shown, the method for balancing and weighing wind turbine blades includes: firstly lifting the produced wind turbine blade 1 with a weighing device, weighing the total weight, and then weighing the moment M. When weighing the moment M , it is necessary to install the support frame 2 at the blade root of the wind turbine blade 1, select any point behind the center of gravity of the wind turbine blade 1 as the lifting point, and keep the blade root section of the wind turbine blade 1 perpendicular to the horizontal plane. Weigh the torque F, and then measure the vertical distance L between the lifting point and the root section of the wind turbine blade 1, so as to calculate the moment M=F·L.
[0011] In order to make the measurement more accurate, the vertical distance between the lifting poi...

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 [0001] The invention relates to a weighing method, in particular to a method for balancing and weighing wind turbine blades. Background technique [0002] In order to ensure the smooth operation of the wind turbine, it is required that the total weight and moment of each blade installed on the wind turbine are basically the same. Gross weight and moment. The traditional weighing method is: first lift the produced blades with a weighing device, weigh the total weight, and then measure the moment. When measuring the moment, the blade needs to be twisted to a certain angle in advance, and the length of the blade must be measured with a tape measure. To determine the weighing lifting point, due to the special shape of the wind turbine blades, it is difficult to measure the position of the lifting point accurately, the operation is cumbersome, and the weighing accuracy cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved ...
