The principle of work of the energy-saving plant blade area measuring equipment that the utility model embodiment provides is:
Blade is placed between the first roll and the second roll, blade is clamped by the first roll and the second roll, pull out blade, drive roll rotation, roll rotation to be slowed down generator rotation by gear driven, thus make generator generation current, then there is current flowing in the first circuit, make the first laser transmitter group produce laser, laser is irradiated on two velometer, because roll rotation can also be rotated by gear driven runner, as the first round through hole on runner and the first generating laser a, first laser pickoff a is in straight line, and second takes turns through hole and the first generating laser b, when first laser pickoff b is in straight line, the laser that then the first laser transmitter group produces can take turns through hole through first round through hole and second, be respectively the first laser pickoff group received, then two velometer is in connected state, thus make second circuit form closed-loop path, because deceleration generator is under roll rotation drives, rotate, generation current, therefore, generation current in second circuit, thus make the second generating laser produce laser, laser is radiated on reflection unit, reflection unit reflects the laser light on threshold switch device, threshold switch device receives the laser of reflection, when the laser intensity reflected is greater than the threshold value of setting, then threshold switch is opened, when the intensity of the reflects laser received is less than threshold value, then threshold switch cuts out.
When the first roll and the second roll shop building place blade, then laser is through blade, and light intensity weakens, and therefore, the intensity of the reflects laser that threshold switch receives is less than threshold value, and threshold switch cuts out.
Then according to the quantity of threshold switch of closing and the width of each threshold switch, both are multiplied, just can obtain the width W 1 of blade when this position.
And when roll is rotated further, continue to drive the runner of two velometer to rotate, because the laser of the first laser transmitter group generation is not by the through hole on runner, can not be received by the first laser pickoff group, therefore, two velometer is in off-state, then second circuit is in off-state, then the second generating laser can not produce laser, can not measure the width of blade when turning over this position.
In the first circuit, when two velometer is in connected state again, in second circuit, the second generating laser produces laser again, records the width W 2 of the page when this position.
If it is 60 that the first round through hole on two velometer and second takes turns through hole, then the number of times of two velometer switch is 60 times, then the length of the blade passed through between twice connected state is 1/60 of two velometer girth; The area of the blade passed through is the trapezoidal area of wide w1 and w2 of leaf and the leaf long h composition recorded for twice.
In the utility model embodiment, adopt two velometer, therefore, in one-shot measurement, carried out twice measurement by different linear velocity resolution respectively, each result measured, the larger value measured under getting two resolution, thus improve the precision of measurement.
Visible, the plant blade area measuring equipment that the utility model embodiment provides, by in blade area measuring process, pull blade, thus make generator generation current, for whole equipment provides electric energy, from achieving oneself supply of electrical energy, without the need to the support of additional power supply, therefore, save electric energy, preferably resolve the problem that field work is subject to the restriction of power supply; Simultaneously, due to the setting of two velometer, the width of two adjacent positions of blade can be measured accurately, and the length between two width, therefore, the area calculating blade that can be automatic accurate, and do not relate to artificial technical factor, namely measurement result is not by the impact of manual operation technology, drawn width and the length of blade completely, thus obtain the area of blade by the structure of equipment self.
In the present embodiment, the first roll 2 and the second roll 3 can be set to multiple respectively.Adopt said structure, blade to be measured can be fixed between the roll of upper-lower position preferably, measuring process is more prone to.
In the utility model embodiment, threshold switch device 8 can be composed in parallel by 100 threshold switches.Meet the measurement demand of the width of most blade, and the setting of unnecessary threshold switch can not be caused, cause the volume increase of equipment or the waste of resource.
