Description

From the static solar cooker of motion tracking focus

One, affiliated field

Present technique belongs to solar energy development and utilizes the field, it is in my utility model patent technology---it is perfect that development is followed the tracks of on the basis of rotating mechanism (patent No.: ZL 200420096616.5) in the solar energy electric control automatically, from the static solar cooker of motion tracking focus is a kind of tracking solar cooker of special structure form, it can allow solar stove panel poly-sunshine focus transfixion on whole three dimensions.

Two, background technology

The solar energy electric control is followed the tracks of rotating mechanism patent (patent No.: ZL 200420096616.5) automatically rotating disc type mechanism has been adopted in the east-west direction tracking of automatic tracking solar equipment, greatly reduce mechanism's center of gravity, but adopt the tracking solar equipment of this technology still to exist many deficiencies, such as: solar energy reflector poly-focus be to move at any time on the locus, like this, certainly will require tracking solar equipment heat collector and solar energy reflector to be designed to one, increased virtually to tracking motor and dragged load and be designed to one, in addition, the solar energy reflector also must design to such an extent that intensity is enough big, to satisfy the requirement of strength of bearing heat collector.

Present solar cooker is not broken away from directly the thinking that optically focused focus or perhaps solar cooker heat collector position and solar stove panel are connected in one, be subjected to the restriction of this thinking, the solar cooker heat collector can not design too heavyly, perhaps too firm, because will certainly increase the weight of the weight of solar stove panel like this, thereby strengthened power requirement virtually from the motion tracking dragging system, because the purpose of solar energy automatic tracking is to realize the accurate tracking of solar stove panel, so, drag a solar cooker heat collector that fills big water gaging or other heated materials and there is no need really.

Present solar energy automatic tracking technology is not broken away from the thinking that directly allows the solar concentrating plate directly rotate yet on thing, north and south both direction, exactly because be subjected to the limitation of this thinking, to making existing solar energy tracking equipment body must design quite hugely, so as to realizing the attack of system keeps track and opposing wind-force, also be subjected to the restriction of this huge body just, make the tracking solar technology slowly not have extensive use.

Three, goal of the invention, content

Deficiency in view of above-mentioned solar cooker and the existence of solar energy automatic tracking technology, I am through ruminating over and testing, finally invented a kind of compact conformation, effect excellence from the static solar cooker of motion tracking focus, it had both had wind resistance, optically focused, characteristics that tracking effect is good, have the motionless all the time advantage of maintenance optically focused focus on three-dimensional space position again, fundamentally realized the disengaging fully of solar cooker follower integral body in other words of solar cooker heat collector and solar stove panel.

The purpose of inventing this technology is that the solar energy tracking technology is applied to production reality as early as possible, allow people develop the solar energy green energy resource as early as possible, because so, the solar cooker heat collector can design to such an extent that have a sufficient intensity fully, enough weight, specific (special) requirements such as multiple use, this technology can accumulate in sunshines up to a hundred or thousands of square metres on the pressure vessel of 3 to 5 cubic metres of insufficient spaces fully, thereby the solar energy automatic tracking technology is directly applied to thermal power generation, perhaps the solar energy automatic tracking technology is applied to the station, harbour, school, factory's tea furnace etc., can be every year that country saves a large amount of electric power like this, from environmental angle, it raises year by year for the inhibition global warming and also has sizable promotional value.

This mainly is by having the follower rotating shaft horizontal direction to change vertical direction on east-west direction from the static solar cooker of motion tracking focus, we can the image it than making the Lazy Susan rotating manner, around rotating disk, weld or be stained with and connect the crimp chain or directly process upward tooth, the east-west direction tracking motor drives a sprocket wheel or gear by reductor, thereby drives dial rotation to realize the tracking of east-west direction by the engagement of sprocket wheel or gear and rotating disk periphery; On North and South direction, mainly be two rotating fulcrums to be set by two on east-west direction rotating disk positions the same above the support post with solar stove panel optically focused focus height, the solar concentrating plate can rotate by two fulcrums, and North and South direction tracking motor and reductor are arranged on the position of rotating disk near central authorities, the North and South direction tracking motor is meshed by a gear of an output gear wheel middle with being arranged on solar stove panel with reductor, thereby realizes the accurate tracking of North and South direction.

Four, description of drawings

Accompanying drawing 1 is from the static solar cooker composition diagram of motion tracking focus.Among the figure: 1 is this door cabinet frame that supports the solar cooker heat collector from the static solar cooker of motion tracking focus; 2 is spherical heat collector; 3 is the coupling part of heat collector and door cabinet frame; 4 is the rotating shaft of being responsible for rotation on the solar panel; 5 is North and South direction rotational support column; 6 is rotary base; 7 are North and South direction transmission of torque half gear; 8 is North and South direction reductor output gear; 9 is the North and South direction motor and speed reducer; 10 is reductor output gear or the sprocket wheel on the east-west direction: 11 are the reductor on the east-west direction; 12 is the tracking motor on the east-west direction; 13 rotating disks for the carrying tracking system; 14 is parabola surface of revolution solar panel.

When system need to be when east-west direction be followed the tracks of, motor 12 drives reductors 11 and rotates, by the reductor output gear on the east-west direction or The rotating disk 13 that sprocket wheel 10 drives the carrying tracking system rotates, thereby realizes the tracking on the east-west direction; When system need to be when North and South direction be followed the tracks of, The North and South direction motor and speed reducer 9 that is fixed on the rotating disk 13 that carries tracking system rotates, by North and South direction reductor output gear 8 and north and south Thereby the direction transmission of torque drives rotating shaft 4 rotations that solar panel 14 centers on responsible rotation on the solar panel with the engagement of half gear 7, and then realizes southern The north to accurate tracking because two rotating fulcrums on two support posts 5 of the rotating disk of design carrying tracking system and solar stove panel 14 The optically focused focus is on the horizontal plane of sustained height, so no matter how solar concentrating plate 14 rotates, door cabinet frame 1 He is being passed through all the time in its focal position In the heart, rotary base 6 mainly is responsible for supporting wheels in the heat collector 2 that coupling part 3 is fixed, and also can increase the weight of rotating disk 13 bottoms simultaneously, The wind resistance of Effective Raise rotating disk 13.

Five, the specific embodiment

What must be noted that a bit is, support shaft fulcrum height that solar panel rotates must with solar panel optically focused focus and heat collector center on same horizontal plane, otherwise this tracking solar cooker can not reach designing requirement.No matter in addition, possess the self-locking wind resistance for making this at any time from static solar stove panel of motion tracking focus and rotating disk, be that used transmission should be Worm-gear type with its final stage ways of deceleration of reductor on the east-west direction or on the North and South direction.In addition, do not influencing dial rotation and guaranteeing under the prerequisite of wind resistance requirement, thereby two columns that support the rotation of solar panel North and South direction can be widened two column spacings by increasing the low frame of prolongation, like this, can under the prerequisite that does not increase the rotating disk manufacturing cost, play the purpose that strengthens solar panel light harvesting area as far as possible.

Six, effect

By practical application, this automatic tracking focus static solar cooker has reached the ideal effect that expection requires fully.
