Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.In literary composition, equilibrium position refers to the target location (as described in utility model content part) of Tracing Control.
Basic scheme of the present utility model is: for follow-up mechanism, directly over four-quadrant photo detector 3 parallel be fixedly installed one with its size, baffle plate 8 that shape is identical; Other parts are identical with background technology, repeat no more.For method,
The shape of whole follow-up mechanism can be the taper as Fig. 1 or the ellipse as Fig. 2.
When solar tracking apparatus departs from equilibrium position, according to drift condition, carry out surface level rotary motion and/or luffing; Detect the signal of the photodetector set in four-quadrant photo detector simultaneously, if signal diminishes, continue corresponding sports along current kinetic direction, until signal is zero, if signal becomes large, the opposite direction along current kinetic direction continues corresponding sports, until signal is zero.
Four-quadrant photo detector 3 comprises four pieces of detectors A, B, C, D being divided by two straight lines X, Y, and Y-axis is pitching turning axle, and X-axis is straight line in surface level.Method of the present utility model, the quantity of the detector having light to irradiate by detection and position are to determine mode of motion, and namely the detector having light to irradiate has the detector of signal.
Be divided into two kinds of situations, the first situation has two pieces of detectors illuminated, if these two pieces of detector adjacent edges are straight line X, then only carries out luffing; If the adjacent edge of these two pieces of detectors is straight line Y, then only carry out rotary motion in surface level.As only C, D are illuminated, then equilibrium position can be reached by luffing.Only B, C are illuminated, then can reach equilibrium position by rotary motion in surface level.
The second situation has three pieces of detectors illuminated, then need first to carry out luffing and carry out rotary motion in surface level again, or first carry out rotary motion in surface level and carrying out luffing, and order can be selected.
The first situation, irradiated detector is two pieces, carries out rotary motion in pitching or surface level in certain direction, detect the signal of wherein any one detector, if signal becomes large, change direction of motion, until signal is zero, if signal diminishes, continue the motion of this direction, until signal is zero.As only C, D are illuminated, carry out luffing in the direction of the clock, detect the signal of C or D, if signal becomes large, change counterclockwise pitching into, until signal is zero, if signal diminishes, continue clockwise pitching.In like manner, only B, C are illuminated, carry out rotary motion in surface level in the direction of the clock, detect the signal of B or C, if signal becomes large, change rotary motion in anticlockwise horizontal face into, until signal is zero, if signal diminishes, continue rotary motion in clockwise surface level.
The second situation, irradiated detector is three pieces.The adjacent edge of two pieces of detectors then must be had to be straight line X, and the adjacent edge of two pieces of detectors is straight line Y, and two pieces is the position relationship at diagonal angle.When carrying out luffing, choose in three pieces of illuminated detectors, diagonal position relation is in one piece of illuminated detector, and can with the detector of another block illuminated detector common adjacency limit straight line X, detect its signal, if signal becomes large, change direction of motion, until signal is zero, if signal diminishes, continue the motion of this direction, until signal is zero.Similar, when carrying out rotary motion in surface level, choose in three pieces of illuminated detectors, be in diagonal position relation with one piece of illuminated detector, and can with the detector of another block illuminated detector common adjacency limit straight line Y, detect its signal, if signal becomes large, change direction of motion, until signal is zero, if signal diminishes, continue the motion of this direction, until signal is zero.
For example, as shown in Figure 3, along with passage of time, position of sun offsets, light angle changes, and baffle plate 8 can not shelter from the sunray that the glass lens 6 installed from unthreaded hole 4 is injected completely, namely deviate from equilibrium position, wherein three pieces of detector B, C, D local in photodetector 3 receive a part of sunray, thus produce voltage signal.Signal processor distinguishes out the voltage of B, C, D photodetector, passes to performance element.Here first carry out the rotary motion in surface level, according to rule above, B is in and is in diagonal position relation with D, and can with C common adjacency limit straight line Y, so the signal of B should be detected, if when rotating to certain direction, the voltage of B increases on the contrary, then rotate in the other direction at once, until the loss of voltage of B; If when rotating to certain direction, the voltage of B reduces gradually, then continue to rotate to this direction, until the loss of voltage of B, as shown in Figure 4.When the loss of voltage of B, then drive follow-up mechanism along Y direction luffing, now should detect the signal of D, if rotate to certain direction, the voltage of D increases on the contrary, then rotate in the other direction at once, until the loss of voltage of D; If when rotating to certain direction, the voltage of D reduces gradually, then continue to rotate to this direction, until the loss of voltage of D.Now, sunray is vertical with follow-up mechanism, and light is all blocked by baffle plate, gets back to equilibrium position, reaches tracking object, as shown in Figure 5.
Be presented above a kind of concrete embodiment, but the utility model is not limited to described embodiment.Thinking of the present utility model is above-mentioned basic scheme, and for those of ordinary skill in the art, according to instruction of the present utility model, designing the model of various distortion, formula, parameter does not need to spend creative work.The change carried out embodiment when not departing from principle of the present utility model and spirit, amendment, replacement and modification still fall in protection domain of the present utility model.
