A kind of curvilinear motion control device of solar thermal collector
The utility model relates to the auxiliary equipment of a kind of solar energy, especially relates to the curvilinear motion control device of a kind of solar thermal collector.
Solar thermal collector is the critical piece converting the solar into heat energy, and its quality and installation direction directly affect the utilization rate of solar energy.The phototropic face of most at present sunrays and solar thermal collector out of plumb, affected bigger by season, the meteorological condition such as round the clock and rain or shine, the utilization of solar energy and conversion efficiency are relatively low, and device of solar generating can not generate electricity continuously, the cost of solar panel is also higher, limits the application of solar electrical energy generation equally to a certain extent.Such as filing date 2015. 04. 09, Authorization Notice No. is the Chinese patent of CN 204462871 U, discloses a kind of solar panel automatic spot-following device, and its structure is complex, follows the tracks of light insufficient, there is dead angle;Further, since the invasion and attack of the weight of self and natural wind, drive mechanism needs the bigger load of carrying, causes drive mechanism bulky insecure, and durability is not enough, it is difficult to carry out large scale application in solar energy industry.
Development with technology, a kind of tracker being provided with photo resistance has occurred on the market, when position of sun leaves detection faces front and is in certain angular position, sunshine is because the power that black clouds or other weather reasons are caused can allow controller cause erroneous judgement, make solar thermal collector that situation about running back and forth to occur, significantly increase loss, it is therefore necessary to improve prior art.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, provides the curvilinear motion control device of a kind of solar thermal collector, solves solar thermal collector and utilize the low problem of sun energy rate.
For reaching above-mentioned purpose, the utility model by the following technical solutions:
A kind of curvilinear motion control device of solar thermal collector, including base, the motor of PLC control is installed on described base, being provided with gear on the output shaft of described motor, the engagement of described gear connects tooth bar, and described tooth bar can slide on base, expansion link is fixedly mounted on described tooth bar, installing solar thermal collector on described expansion link, described base being installed with pole, described pole is hinged with expansion link.
Preferably, described PLC can control after motor rotated 12 hours in the middle of one day in one direction and sets back, and continues to rotate after static 12 hours
Preferably, the length of described tooth bar and swingle top rotate the half of girth around pin joint.
Further, the lower end of described solar thermal collector is provided with bracing frame, is provided with Universal rotary rotating shaft between described solar thermal collector and bracing frame.
Wherein, described motor is reducing motor.
In this device, reducing motor driven gear turns clockwise, gear driven tooth bar moves, pin joint on pole for the expansion link is driven to rotate during movement, expansion link elongates or shortens during rotating, being arranged on the arcuately curvilinear motion of the solar thermal collector on expansion link and support bar, PLC controls solar thermal collector run duration from east to west.The utility model simple in construction, cost is relatively low, and the friction between rack-and-pinion is less, and gearratio is higher, suitable large-scale promotion application.
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: the 1st, solar thermal collector, the 2nd, base, the 3rd, pole, the 4th, expansion link, the 5th, tooth bar, the 6th, reducing motor, the 7th, gear, the 8th, bracing frame.
Detailed description of the invention
With embodiment, the utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of curvilinear motion control device of solar thermal collector, including base 2, the reducing motor 6 of PLC control is installed on described base 2, described PLC can control reducing motor 2 and rotate 12 hours in the middle of one day in one direction, then inversely go back to, continue after static 12 hours to rotate.Being provided with gear 7 on the output shaft of described reducing motor 6, the engagement of described gear 7 connects tooth bar 5, and the length of described tooth bar and swingle top rotate the half of girth around pin joint.Described tooth bar 5 can slide on base, and described tooth bar 5 fixedly mounts expansion link 4, described expansion link 4 is installed solar thermal collector 1, described base is installed with pole, and described pole is hinged with expansion link.In order to reinforce solar thermal collector 1, in the lower end of described solar thermal collector 1, bracing frame 8 is installed, between described solar thermal collector 1 and bracing frame 8, Universal rotary rotating shaft is installed, can guarantee that expansion link 4 drives solar thermal collector 1 flexible rotating during doing curvilinear motion.
Use of the present utility model and motion process are as follows:
During use, first by the panel of solar thermal collector 1 towards east, tooth bar 5 is arranged on below gear 7 near the side of expansion link 4, open the switch of reducing motor 6, reducing motor 6 driven gear 7 turns clockwise, gear 7 carries carry-over bar 5 north to move, pin joint on pole 3 for the expansion link 4 is driven to turn clockwise during movement, expansion link 4 extends during rotating, the solar thermal collector 1 arcuately curve being arranged on expansion link 4 and support bar 8 westwards moves, PLC control solar thermal collector 1 run duration from east to west is 12 hours.After solar thermal collector 1 runs to west, PLC control solar thermal collector 1 is returned original state, and continue previous motion after keeping 12 hours, move back and forth successively.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art the technical solution of the utility model is made other modification or equivalent, without departing from the spirit and scope of technical solutions of the utility model, all should cover in the middle of right of the present utility model.
