在太阳能利用的技术领域中实现对日跟踪是比较耗资费力的。对于家庭使用的太阳能设备,如太阳灶、太阳电池方阵、热水器等,对日跟踪技术由于耗资较大,实际应用很少。然而,有些太阳能设备又必须对日跟踪。这里介绍的“对日定向跟踪装置”解决了上述问题,既耗资不大,又简单实用。与目前国外已有技术相比具有许多优点,突出的优点是实用。右图所示是本专利的一种典型结构。转动主轴1用来支承聚光器并传递转动。其上有两条对称的螺旋滑槽,在图中用曲线表示。滑槽的升角大于螺旋自锁角。主轴上端与聚光器相联,下端与止推轴承3相配合。
In the field of solar energy technology to achieve the day tracking is more costly. For domestic use of solar energy equipment, such as solar cookers, solar cells square, water heaters, etc., Japan tracking technology due to greater cost, little practical application. However, some solar devices must track Japan again. The “directional tracking device to Japan” introduced here solves the above problems, which is not only costly but also simple and practical. Compared with the current foreign technology has many advantages, the outstanding advantage is practical. The picture on the right shows a typical structure of this patent. The spindle 1 is rotated to support the condenser and transmit rotation. There are two symmetrical helical chutes on it, shown graphically in the figure. Chute angle greater than the self-locking screw angle. The upper end of the spindle is connected with the condenser, and the lower end is matched with the thrust bearing 3.
