Embodiment

In order that those skilled in the art are better understood from the utility model, it is real below in conjunction with the utility model The accompanying drawing in example is applied, clear, complete description is carried out to the technical scheme in the embodiment of the utility model, it is clear that described Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the reality in the utility model Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all should When the scope for belonging to the utility model protection.

Shown in reference picture 1-3, a kind of novel solar energy light gathering device, including base 1, thermal-collecting tube 9, it is movably connected on base On support 2 and multigroup catoptric arrangement 3, under external force, support can realize rotation relative to base, specifically, Yu Benshi Apply in example, promote support to realize come back rotation by being mounted with a rotating driving device below support；Multigroup reflection knot Structure 3 is evenly arranged on support 2, be provided between every group of catoptric arrangement can the gap that passes through of air feed, pass through both ends and carried out with support It is fixed；During except first installation, catoptric arrangement and support are always geo-stationary, and in the course of work, catoptric arrangement is with branch What frame moved together；The sunlight that all catoptric arrangements are reflected all is concentrated on thermal-collecting tube 9, and thermal-collecting tube 9 is connected with support, work During, follow support to be synchronized with the movement together；The utility model substantially reduces wind by setting the catoptric arrangement of multiple group type Resistance；By catoptric arrangement and support synchronization action, by driving arm to promote the motion of whole mirror field, transmission knot is simplified Structure, reduces parts, and processing assembling is more convenient, the flexibility that also add operating, the precision and luminous energy for improving optically focused Utilization rate.

Specifically, the catoptric arrangement 3 includes speculum 31, in the present embodiment, speculum is planar structure, reflection Mirror 31 is connected by bolt and support；In other embodiment, in order to improve focusing ratio, speculum can also be arranged to the differential of the arc Shape, specifically, setting connector on support, the connector is connected with support, and connector carries out the both sides of speculum pico- Extruding so that speculum carries out concave deformation, forms arc curve mirror structure, the specific structure of connector is not shown in figure Meaning, but any connector that can make mirror deformation camber structure belongs to the scope of protection of the utility model；

Further, the rotating driving device includes driving part 4 and transmission parts 5, one end of transmission parts 5 and drive The transmission of dynamic component 4 coordinates, and the other end is connected with the support 2.

Specifically, driving part 4 is stepper motor, transmission parts 5 are screw structure, and both all can be by buying on the market The step-by-step control system of sale is realized；Driving stepper motor screw structure moves up and down, and screw structure upper end is consolidated with support Even, holder pivots are then driven.

In other embodiments, can be in the connection of support and base in order to reduce the rotational resistance during holder pivots Place's installation bearing 6, reduces the frictional force between support and base, reduces energy consumption.

As an improvement, the side of the base 1 is mounted with lifting structure, the lifting structure can promote the side of base real Existing upper and lower displacement.Lifting structure can be electronic or manual；Specifically, in the present embodiment, the lifting knot Structure is manual, including the fixed seat 8 and screw rod 82 that can be detachably connected with base, and multiple interval settings are provided with fixed seat 8 Screw 81, the spacing size between each screw 81 can set as needed；Simultaneously identical is also offered on base Screw, screw rod are engaged with screw, after setting specific height, by screw rod through the screw 81 in fixed seat, are then revolved again Enter in the screw on base, base and fixed seat are realized and fixed；The lifting structure of manual mode, easy to process, manufacturing cost It is low.

Due to the rule of sunshine change, it is divided into Four seasons change, just needs in a season to change the angle of support again, so only Manual lifting structure is needed, so as to reduce cost, the part of lifting structure required for reduction, the lifting structure only needs south North orientation is placed, and East and West direction follows the sun to rotate, it is only necessary to which East and West direction tracks, it is not necessary to is tracked in north-south, is reduced the throwing of tracking Provide cost (only needing single-direction tracing).One lifting structure can also be set respectively in the both sides of base, can when so installing for the first time With the lifting structure of random putting position, as needed unlatching side.

In order to sense ray position in real time, automation mechanized operation is realized, we are also provided with PLC and installed in support On photosensitive device 7, photosensitive device 7 and driving part 4 be used to sense ray position with controller Electricity Federation, photosensitive device respectively, And as support is synchronized with the movement；

Work process：In use, switching on power first, when the position of the sensing sunlight of photosensitive device 7, the position of the sun is believed Breath sends controller to, after controller receives instruction, and then controller is sent pulse, further indicates that motor is opened Begin rotate, drive screw structure drive support 2 follow the sun to rotate, adjust all catoptric arrangements 3 to angular.When reflection is tied After incident sunlight, photosensitive device 7 stops sending signal to control structure 3, completes this to light.When sun move angle surpasses 0.5 degree is crossed, photosensitive device 7 senses that position of sun changes, and repetition is above-mentioned to photoreduction process, so circulates to reach tracks sunlight Purpose, more fully utilize sunshine.In the case that photosensitive device 7 does not sense sunlight, controller can by setting when Between tracking mode continue to track, the four seasons and one day at different moments, it is different as solar motion angular speed and caused by tracking error, It will search for sunlight automatically when induction installation 7 senses sunlight, reach accurate tracking.When light intensity be weaker than certain value or When the evening draws on, system automatically restores to initial position, is easy to next day to start working, and at night (non-working time), entirely System automatically powers off, and decommissions, to have the function that energy-conservation, protection, extend electrical equipment service life.

The heat energy of solar energy heat utilization device acquisition higher temperature can be made using the product of this concentrator, so as to expand the sun The application of energy.Such as with photovoltaic cells, the usage amount of photovoltaic cell can be greatly reduced, reduce total amount of investment, dropped The cost of electricity-generating of low photovoltaic cell.Also the fields such as solar-powered heating generating, solar water heater be can be directly used for.

Above-mentioned embodiment is used for illustrating the utility model, rather than the utility model is limited, Spirit of the present utility model and any modifications and changes in scope of the claims, made to the utility model, all fall Enter the scope of protection of the utility model.
