Description

From the motion tracking solar cooker

The utility model relates to the application of solar heat, especially a kind of can be from the motion tracking sun, with utilize solar heat from the motion tracking solar cooker.

The Chinese patent communique disclosed a kind of name and was called " the technical scheme of tracking sun formula plate glass kitchen range (CN10191819A, 9310166 ° of application numbers).This scheme is by a underframe, can be on underframe be the rotating disk that rotate in the center of circle with a rotating shaft, device is on rotating disk and have compositions such as reflection frames of polylith plane rear reflector.It is that the center of circle is rotated and followed the tracks of the sun with the rotating shaft that this solar cooker utilizes a timing controller to control reflection frames, cooperate manual adjustment plane rear reflector that the sunshine of reflection is overlapped simultaneously, with the purpose of finishing optically focused and following the tracks of the sun, but not enough is that this solar cooker must be by the angle of manual adjustment plane rear reflector, very inconvenient during use, and this scheme has only the automatic adjusting (utilizing timing controller control rotating disk is that rotate in the center of circle with the rotating shaft) of a direction, reach to make that sunshine is poly-all the time to be any difficult realization of purpose with the heating heated object.

The purpose of the utility model, be at the deficiency of above-mentioned technology and provide a kind of can be comparatively accurately from the motion tracking sun, its focusing effect better and easy to use from the motion tracking solar cooker.

The utility model purpose can realize like this: a kind of from the motion tracking solar cooker, it comprises: the support that supports heated object, reflection frames, the bearing support of supporting reflex framework, be used for device plane rear reflector and be distributed in the back shaft of described reflection frames, it is characterized in that describedly also comprising from the motion tracking solar cooker:

A sunshine horizontal reflection controller, this controller comprises two sensors that lay respectively at described heated object horizontal center line two ends, one is positioned on the described reflection frames micromachine I of rotating with the signal that receives described two sensors, and is driven and transmission mechanism that the back shaft in the described reflection frames is rotated simultaneously in the same way by described micromachine I.

A sunshine vertical reflection controller, this controller comprises two sensors that lay respectively at described heated object vertical center line two ends, one between the described reflection frames back side and support frame as described above and can accept the signal of two sensors and the micromachine II of rotating, and the angle transmission mechanism that links to each other with described micromachine II and the angle on described reflection frames and ground is changed.

Transmission mechanism in the described scheme comprises: the gear (9) that is meshed with described micromachine I axle, drive screw (6), device is at drive screw (6) one ends and the travelling gear (8) that is meshed with described gear (9), and an end device is at the nut (5) of described drive screw (6) other end; Nut (5) other end is connected with pull bar (10), is equipped with on the pull bar (10) to make the described crank (18) that is distributed on the back shaft equidirectional rotation simultaneously in the reflection frames.

Described angle transmission mechanism comprises: the gear (9) that is meshed with described micromachine II axle, drive screw (6), device is at drive screw (6) one ends and the travelling gear (8) that is meshed with described gear (9), and is contained in the nut (5 ') between described drive screw (6) other end and described reflection frames (3) upper rear portion.

The main points of described scheme are to be provided with at heated object periphery (referring to Fig. 5) to be divided into two groups and lay respectively at the X coordinate of this heated object and four sensors on the Y coordinate, this two sensors constitutes two automatons (the vertical and horizontal reflection controller of sunshine) with transmission mechanism and angle transmission mechanism respectively, respectively the angle of reflection of the plane rear reflector in reflection frames and the reflection frames is controlled.Only need during use the Y reference axis of heated object is aimed at the sun track of middle motion on high, the light source that then reflexes to heated object no matter take place X or Y to skew, all can take a sample by sensor, the angle of angle by regulating the plane rear reflector or reflection frames and automatically reflection source is aimed at heated object again, focusing effect is comparatively desirable.

Compare with prior art, the utility model not only can reflex to heated object with sunshine comparatively exactly from the motion tracking sun owing to be provided with sensor and the corresponding regulating device of regulating automatically, and focusing effect is better, and uses very simple and convenient.It has overcome the shortcoming of prior art, has reached the purpose of the utility model.

The utility model has following accompanying drawing, and accompanying drawing shows an example of the present utility model.

Example be described as follows (referring to Fig. 1-Figure 10):

The 1-heated object is pot in this example.The 2-support.The 3-reflection frames.The 4-bearing support.In this example by nut (5), drive screw (6), micromachine I (7), travelling gear (8), gear (9) constitute transmission mechanism (referring to Fig. 3).By nut (5 '), drive screw (6), micromachine II (7 '), travelling gear (8), gear (9) constitute angle transmission mechanism (referring to Fig. 4).A, B, C and D represent a sensor (optional thermistor) respectively, and wherein A all becomes one group with the C structure, lay respectively at the X-axis line two ends of heated object (1); B and D constitute one group, lay respectively at the Y-axis line two ends (referring to Fig. 5) of heated object (1).The 10-pull bar.11-plane rear reflector.By intermediate plate (12), clamp (13), screw (14), nut (15) and pad (16) constitute the plane rear reflector are loaded on assembly on the vertical bolster (17) that is distributed on (referring to Fig. 2, Fig. 7, Fig. 8) in the reflection frames (3) in the example.18-installs the crank between pull bar (10) and bolster (17) respectively.The 19-screw, 20-nut, 21-pin.

The example course of work:

When solar irradiation is incident upon reflection frames (3), make the optically focused focus be incident upon pot (1) end by manual adjustment reflection frames (3) and plane rear reflector (11).

If make the skew of optically focused focus generation X axis for a certain reason, then signal is reached micromachine I (7) (referring to Fig. 5, Fig. 3) by sensors A or C, micromachine I (7) forward or reverse, draw or pushing drawing rod (10), make crank (18) action, allow each bolster (17) rotate the reposition of optically focused focus simultaneously in the same way.

If owing to mobile or other reason of the sun makes optically focused focus generation Y-axis to displacement, then signal is reached the micromachine II (7 ') of the angle transmission mechanism that is arranged in reflection frames (3) back side by sensor B or D, drive nut (5 ') just reflection frames (3) serves as that axle produces angle displacement with its bottom, makes the reposition of optically focused focus.

Energy in this example can be used battery, and micromachine can be used direct current generator.Because the rotating control technology of direct current generator belongs to known technology, so this example is not introduced it.
