There is the solar panel blocking function
Technical field
The utility model relates to a kind of solar panel, and particularly a kind of have the solar panel blocking function.
Background technology
The installation of current solar panel mainly consider plate face towards, make it have good light angle.The front of solar panel is directly exposed to outside all the time.When solar panel does not use or particularly not using for a long time, front is unobstructed, has a large amount of dusts or leaf or other foreign material and falls thereon, effectively can not block protection time inactive to solar panel.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, flexible movements are reliable, solar panel can carry out blocking protection between lay-off period, improve its useful life there is the solar panel blocking function, overcome the deficiencies in the prior art.
Of the present utility model have the solar panel blocking function, comprise the solar panel plate body be fixed on backboard, the periphery of described backboard has external part, the external part being positioned at side is equipped with micromachine, the output shaft of micromachine is connected with the first axle, first axle, by clutch shaft bearing seat and bearings, the first axle is equipped with a pair sheave; The external part being positioned at opposite side has fabric spool by the second bearing pedestal and bearings, fabric spool is equipped with torsion spring mechanism, the torsion that torsion spring mechanism produces orders about fabric spool all the time and rolls around the fabric on fabric spool; The outer end edges of fabric connects with one end of stay cord, and another termination of stay cord is fixed on described sheave, and stay cord has two, fixes respectively with two sheaves, and two stay cords connect with fabric outer end edges both sides edge respectively.
Of the present utility model have the solar panel blocking function, and when normally using at ordinary times, under the twisting force of torsion spring mechanism, fabric is by rolling on fabric spool, and be namely wrapped on fabric spool, now fabric does not block the front of solar panel.When stopping using; when particularly not using for a long time; can start micromachine, driven by motor first axle and sheave are rotated, and stay cord is wrapped on sheave; pull fabric to stretch out simultaneously; when fabric stretches out, the torsion of torsion spring mechanism is overcome, and blocks the front at solar panel after fabric is drawn out, and can effectively prevent dust, foreign material etc. from dropping on solar panel; play a very good protection, improve its useful life.
Accompanying drawing explanation
Fig. 1 is the structural representation drawing of the utility model embodiment;
Fig. 2 is the schematic top plan view shown in Fig. 1.
Embodiment
As shown in Figure 1, 2: 2 is solar panel, and be fixed with backboard 1 at the back side of solar panel 2, the periphery of backboard 1 has external part, and namely backboard 1 is greater than solar panel 2, all has the external part of backboard 1 at the periphery of cell panel 2.The external part being positioned at side is provided with micromachine 7, and the output shaft of micromachine 7 is connected with the first axle 10, first axle 10 by clutch shaft bearing seat 8 and bearings by shaft joint, and the first axle 10 is equipped with a pair sheave 9.
The opposite side external part being positioned at backboard 1 has fabric spool 4 by the second bearing pedestal 3 and bearings, fabric spool 4 is equipped with torsion spring mechanism 11, the torsion that torsion spring mechanism 11 produces orders about fabric spool 4 all the time and rolls around the fabric 5 on fabric spool 4.
The outer end edges of fabric 5 connects with one end of stay cord 6, and another termination of stay cord 6 is fixed on sheave 9, and stay cord 6 has two, and fix with two sheaves 9 respectively, two stay cords 6 connect with fabric 5 outer end edges both sides edge respectively.
Of the present utility model have the solar panel blocking function, when normally using at ordinary times, under the twisting force of torsion spring mechanism 11, fabric 5 by rolling on fabric spool 4, namely be wrapped on fabric spool 4, now fabric 5 does not block the front of solar panel 2.When stopping using; when particularly not using for a long time; can start micromachine 7, make micromachine 7 drive the first axle 10 and sheave 9 to rotate, stay cord 6 is wrapped on sheave 9; pull fabric 5 to stretch out simultaneously; when fabric 5 stretches out, the torsion of torsion spring mechanism 11 is overcome, and blocks in the front of solar panel 2 after fabric 5 is drawn out, and can effectively prevent dust, foreign material etc. from dropping on solar panel 2; play a very good protection, improve its useful life.When reusing, back-to-back starting micromachine 7, torsion spring mechanism 11 can make fabric spool 4 rotate backward, and is again rolled by fabric 5.
