Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, preferred embodiment of the present utility model provides a kind of pick-up unit of heliostat transmission accuracy, for detecting the rotary precision of the output shaft 100 of heliostat kinematic train, heliostat (not shown) is in transmission connection on this output shaft 100.Described pick-up unit comprises magnetic railings ruler 1 and read head 2, magnetic railings ruler 1 and read head 2 can gather the angular displacement information of output shaft 100, and the rotary precision of output shaft 100 is obtained by data acquisition system (DAS) (not shown) and signal processing unit (not shown) process, finally feed back to heliostat transmission mechanism control system and control its transmission accuracy.In the present embodiment, described pick-up unit utilizes cheap magnetic railings ruler 1 around the mode be pasted on the outer circumference surface of output shaft 100, replace traditional transmission accuracy detection hardware device, overcome the shortcoming of various severe working environment underdrive precision deficiency, for tower type solar tracking transmission system devises a kind of rationally effective, economical and practical rotating accuracy proving installation.
Particularly, as shown in Figure 1 and Figure 2, this magnetic railings ruler 1 is for being arranged on the outer circumference surface of the output shaft 100 of heliostat kinematic train, and this read head 2 is relative with the position of magnetic railings ruler 1, on the pedestal that read head 2 is fixed on heliostat by support (not shown) or other parts.Have certain gap between magnetic railings ruler 1 and read head 2, both cooperatively interact the angular displacement information gathering output shaft 100.
In the present embodiment, magnetic railings ruler 1 is in banded structure, and magnetic railings ruler 1 is looped around on the outer circumference surface of output shaft 100, makes magnetic railings ruler 1 and output shaft 100 coaxial rotation.Magnetic railings ruler 1 is arranged on the marginal position of output shaft 100 outer circumference surface, during installation, by the justified margin of the side of magnetic railings ruler 1 and output shaft 100, can be convenient to the installation location of magnetic railings ruler 1.This installation locator meams is comparatively accurate, is beneficial to the right alignment ensureing magnetic railings ruler 1 and output shaft 100, thus improves the accuracy of detection of described pick-up unit.In other embodiment of the present utility model, magnetic railings ruler 1 can also be arranged on other position of output shaft 100 outer circumference surface, ensures the smooth of magnetic railings ruler 1 when ensureing during installation to paste, to meet right alignment and the verticality requirement of magnetic railings ruler 1 and output shaft 100.
In this embodiment, output shaft 100 due to the tower type solar angle turned over that to work every day is less than 360 degree, thus magnetic railings ruler 1 need partly be looped around on the excircle of output shaft 100, and correspondingly, also namely the length of magnetic railings ruler 1 is less than the girth of the excircle of output shaft 100.
Preferably, the side of magnetic railings ruler 1 is provided with adhesive linkage (not shown), and magnetic railings ruler 1 is arranged on the outer circumference surface of output shaft 100 by adhesive linkage.Can drive magnetic railings ruler 1 and its coaxial rotation when output shaft 100 rotates, adopt above-mentioned bonding mounting means, its cost is lower, can reduce the cost of described pick-up unit.In other embodiment of the present utility model, magnetic railings ruler 1 is not limited on the outer circumference surface adopting and be arranged on output shaft 100 in the method for paste, and it can also adopt alternate manner to be arranged on the outer circumference surface of output shaft 100.
