The specific embodiment
A kind of solar collector from the motion tracking sun, as shown in Figure 1, 2, comprise the support 1 that fixes on the ground, swingle 2 and the lightweight kitchen range shell 3 that is enclosed within the support outer ring, offer a strip slot 4 along kitchen range shell diametric(al) on the kitchen range shell, the two ends of strip slot are all fully not open-minded, and swingle passes slot; One pot of placing pot for cooking rice is set on the support of the position at kitchen range shell focus place encloses 6, the flexible strand 5 of three suspension kitchen range shells is set on the swingle below pot encloses slightly, the other end of flexible strand is connected on kitchen range shell edge, wherein first flexible strand is arranged on the mid point of strip slot end, the other end of second flexible strand is arranged on the mid point of the end of strip slot about on the centrosymmetric kitchen range shell of kitchen range shell edge, and the other end of the 3rd flexible strand is arranged on other position at kitchen range shell edge; Fixed position and the kitchen range shell focus of flexible strand on swingle is very close, so the variation of focal position can be ignored.Two flat boards 7 of the strip slot place of matching for paralleling with the strip slot on swingle make swingle rotate the rotation of drive kitchen range shell and move; Fix an elevation angle drive motors 8 on the swingle of kitchen range shell below, connect one on the output shaft of elevation angle drive motors and drive flexile hauling cable 9 and a protection flexile hauling cable 14, the other end that drives flexile hauling cable and protection flexile hauling cable is connected to the upper of kitchen range shell edge respectively, these 2 are dropped on the center line of strip slot through kitchen range shell center, the tie point that drives flexile hauling cable drops on the mid point of end of strip slot, drives flexile hauling cable opposite with the coiling direction of protection flexile hauling cable on the output shaft of elevation angle drive motors; The swingle lower end arranges a bearing 10, belt pulley 12 is set on the bearing outer, be arranged on the motor shaft of ground azimuth drive motors 11 and also be provided with belt pulley, be provided with driving belt 13 on two belt pulleys, and then make the azimuth drive motors rotate drive the second bearing rotation and then drive the rotation of kitchen range shell.
When the kitchen range shell is followed the tracks of solar motion; drive flexile hauling cable by the elevation angle of folding and unfolding rope regulation stove shell, when driving the flexile hauling cable rolling, the protection flexile hauling cable is put rope; otherwise opposite, the kitchen range shell is in all the time both sides and is balanced the state of straining at and avoids external environment on impact and the impact of kitchen range shell like this.
The elevation angle drive motors is connected with single-chip microcomputer respectively with the azimuth drive motors, single-chip microcomputer contains each computing formula and each rolling length of driving flexile hauling cable corresponding to elevation angle constantly constantly of sun altitude, drives the rolling of elevation angle drive motors with this and drives flexile hauling cable and make the kitchen range shell follow the tracks of the sun in short transverse to move; Also contain simultaneously the computing formula of each moment solar azimuth and the angular relationship of each azimuthal size of moment and the rotation of azimuth drive motors in single-chip microcomputer, can realize that the kitchen range shell rotates from the motion tracking sun by elevation angle and the azimuth of regulation stove shell.
(sun altitude is certain point and the line of the sun and the angle between ground level on earth surface to the computing formula of sun altitude, uses
Expression for just, is negative to the nadir direction to zenith direction):
Wherein,
Be local geographic latitude,
Be hour angle,
Be red caudal horn, the computing formula of red caudal horn is as follows:
, wherein
It is the ordinal number of some day in 1 year.
Single-chip microcomputer calculates elevation angle according to the elevation angle formula
As shown in Figure 3, the H point is to hang the position of the close kitchen range shell focus of the first rope on swingle, the C point is the link position of driving flexile hauling cable of the motor output shaft of elevation angle drive motors, initial time, the line of first, second flexible strand is HB and HD, and the driving flexile hauling cable is CB; In another moment after rotating a period of time, the line of first, second flexible strand is for being HE and HF, and the driving flexile hauling cable is CE, and the sun altitude of this moment is
,
, solve thus
,
Be elevation angle, can calculate by the instant formula of sun altitude,
For the angle of flexible strand and the plane of reflection is known, therefore can calculate
, and flexible strand length HB and the flexible strand hitch point on swingle is also known to the distance H C of elevation angle drive motors, the length that drives flexile hauling cable can solve into:
, wherein
Be the length HB of flexible strand,
Be HC; Each length computation that constantly drives flexile hauling cable out after, the number of degrees that can need rotate according to the difference computed altitude angle drive motors of adjacent two units driving flexile hauling cable have constantly realized that the kitchen range shell follows the tracks of sun altitude and move.
The computing formula of solar azimuth (solar azimuth be the line of certain point on earth surface and the sun at the projection on ground level and the angle between south orientation, be expressed as
):
。Calculate the azimuth in the morning,
Greater than 0, calculate
Less than 180
As long as add 180
Get final product; Calculate the azimuth in the morning,
Less than 0, solve
Greater than 180
As long as deduct 180
Get final product.
Single-chip microcomputer calculates the azimuth according to formula, and then the radius ratio according to two belt pulleys draws the angle that the drive motors needs rotate, such as, the azimuth is
, the radius ratio of the belt pulley on the belt pulley on the second bearing and azimuth drive motors is 2:1, the azimuth drive motors will be controlled output shaft rotation 2
Single-chip Controlling this moment azimuth drive motors rotates an angle, 2 times of two moment azimuth differences that this angle is rotated for this and rotated last time, the direction that the positive and negative representative of difference is rotated, the direction of rotating is realized by forward, the counter-rotating of azimuth drive motors, and then realizes the movement of kitchen range shell tracking solar azimuth.
When the kitchen range shell is followed the tracks of sun rotation, the invariant position of focus, just the direction of pot reception heat changes, and does not affect the utilization ratio of solar energy.
In addition, if solar receiver is rotatable, can support be set in above-described embodiment, as shown in Figure 4, the motor shaft of swingle 2 direct azimuth drive motors with fixing on the ground is fixed together by shaft coupling 13, and the azimuth drive motors rotates the driven rotary bar and rotates.Arranging equally like this can realize good effect of the present utility model.
In addition, as shown in Figure 5, can not satisfy the tracking sun altitude if calculate the length of strip slot on the kitchen range shell according to the latitude of locality, the strip slot can be extended to the kitchen range shell outside, the strip socket portion of kitchen range shell outside forms by fixation with steel wire, its end-enclosed, at this moment, first flexible strand is fixed near the strip slot kitchen range shell edge but not the strip slot passes on the extended line at kitchen range shell center, drives on the steel wire at center that flexile hauling cable is fixed on strip slot end; The length of strip slot can satisfy in the situation of local latitude fully, and the kitchen range shell is followed the tracks of the sun and rotated.
