Description
Technical field
The utility model relates to the reverberator compacting element in a kind of solar thermal collector, particularly a kind of heavy balance reverberator of line focus fresnel solar arrays.
Background technology
With array way cluster distributing line focusing fresnel reflector and to same thermal-collecting tube reflect focalization, be prior art thereby form the solar heat array.For tracks sunlight; Reflector design becomes rotatable mode, and the reverberator rotation that drives the cluster distribution needs to consume energy, and; If it is bigger that reverberator rotates required moment; Also can bring rotate have some setbacks, weak point such as damage easily, yet, the above-mentioned weak point of reverberator ubiquity of the prior art.
Summary of the invention
The purpose of the utility model is to overcome weak point of the prior art, and a kind of smooth and easy, as to consume the line focus fresnel solar arrays that energy is less, indefatigability is damaged heavy balance reverberator that rotates is provided.
The purpose of the utility model realizes through following approach.
The heavy balance reverberator of line focus fresnel solar arrays; Comprise catoptron, reflector mount, rotating shaft and support; Catoptron is installed on the reflector mount and forms rotor, and reflector mount is supported on the support through the rotating shaft rotation, and it is formed main points and is: rotating shaft core is positioned on the reflection direction of catoptron; And this rotating shaft core also is positioned at the thickness of catoptron.
Catoptron is a basal plane according to its reflection cambered surface; Side, concave arc place is a reflection direction, and side, convex arc place is a back side direction, and the reflection direction of indication is not that what be is the reflected ray direction here; But refer to the direction of that face at reflected ray place, promptly side, concave arc place is a reflection direction.
The distance of catoptron cancave cambered surface between up and down at the bottom of line and the concave arc on two summits is the thickness of catoptron.
In order to reduce the rotating torque of reverberator, should shorten rotating shaft core and overlap until the two with the distance of rotor (catoptron and reflector mount) center of gravity; Because some catoptron need overturn 180 °, if this rotating shaft core is positioned at outside the thickness of catoptron, will extraly take up room again, it is not compact to cause whole solar array.
In order to make catoptron arranging that compact as far as possible (minimum spacing between the catoptron is 1/2 o'clock of catoptron width in theory; Can guarantee that catoptron can freely overturn; But in fact because the thickness of catoptron and necessary free gap, should greater than the catoptron width 1/2) situation under overturn, and possess certain rigid again; (Width) middle part of catoptron and two end portion thickness are smaller, so that the upset of catoptron.And between the middle part of catoptron and two ends, especially near the position of two ends, can be thicker, to increase the rigidity of catoptron.
The purpose of the utility model can also realize through following approach.
This rotating shaft core is positioned at 1/2nd thickness of catoptron.
Though catoptron is a concave and arcwise; But after it is installed in reflector mount; Whole rotor center of gravity is positioned at 1/2nd thickness of catoptron mostly, and reflector mount also is controlled at the rotor center of gravity in 1/2nd thickness of catoptron through design generally by section bar welding or fastening forming easily.
Further optimize and be:
This rotating shaft core is positioned on the line of symmetry of catoptron Width.
The catoptron cancave cambered surface direction between two summits up and down is Width.
Further optimize and be:
Rotating shaft core overlaps with the rotor center of gravity.
Can obtain zero rotating torque like this.
Also have the another kind of scheme that obtains zero rotating torque:
A kind of balance bob is set, and this balance bob is connected with rotor, and is arranged on the extension line of rotor center of gravity and rotating shaft core line.
Obviously the rotating torque of utilizing this balance bob can balance to bring owing to rotor deviation of gravity center rotating shaft core.
Balance bob can be a kind of pendulum model structure, comprises the elongated body of rod and the hammer body of tail end, and the body of rod other end is connected on the rotor.
Balance bob is installed in the end of mirror length direction, and in the rotation direction of catoptron, balance bob can be with respect to 360 ° of rotations of catoptron, so that seek the position of balance during adjustment.
Further optimize and be:
The body of rod is fastenedly connected through a kind of structure and rotor of screw bolt.
Like this, balance bob is exactly the adjustable adjustable counterweight of a kind of moment.
Swivel bearing connected mode about reflector mount and rotating shaft can further be optimized for:
The reflector mount two ends are coaxially arranged with rotating shaft respectively, and the corresponding support and connection of this two rotating shaft are in the supported hole of support.
Like this, whole rotor is striden on support.
Catoptron and reflector mount extend along its length direction, and length is longer, and a this mode of striding is simple in structure, and rigidity is better.
In sum, the utility model is compared prior art and had following advantage: rotating torque is little, and the rotational energy of consumption is less, and indefatigability is damaged, and compact conformation take up room less, easy manufacturing simple in structure.
