Abstract

The utility model discloses a solar energy tracking time controlling drive device specially used for solar energy utilization equipment. The device can be manually operated once to shake the handgrip of a time controller, in order to wind a steel wire rope which has a weight drop at the other end of a steel wire rope onto an incipient wheel which is positioned in the time controller, and then a rotary frame is adjusted to aim to the sun and is fixed by a fastener, the steel wire rope is fastened on a driving wheel to lead the weight drop, the rotary frame, and the time controller to became a linked body, the weight of the weight drop drives the driving wheel and the time controller to rotate at the same time, the clock pendulum of the time controller has a timing function to slowly release the steel wire rope, the releasing length of the steel wire rope in twelve hours equals to a half cycle length which is wound on the driving wheel, meanwhile, also equals to the moved 180 degrees of the sun in twelve hours. The utility model meets the moving speed of 15 degrees per hour, achieves the requirements of the adjustment of once per day, and a whole day tracking.

Description

Drive unit when solar energy tracking is used control

Affiliated technical field

The utility model designs at some solar utilizing equipment, not only can improve its utilization rate, and what have can also save a lot of frequent adjustment time, for example solar cooker, because focus on, directionality is very strong, just needed to adjust once in several minutes, otherwise focus departs from, and it is impossible that use becomes.So the appearance of solar cooker, though a century is had a surplus, the user is very few, adopt this device after, only need harmonize once every day, just tracking illumination was accomplished the popular equipment of high efficiency and time conservation according to one day automatically.

Background technology

Present solar cooker is that the kitchen range face is rack-mount, can horizontally rotate also and can face upward the adjustment of bowing, because at sunlight ceaselessly under the working order, just need remove to adjust a sub-level and pitch angle every several minutes, align sunlight again, early transferring does not need, and can not transfer again evening, in case forgotten, water is cool again on the contrary.Therefore, be an anxious problem certainly that is situated between of waiting.

Summary of the invention

In order to overcome above-mentioned shortcoming, the utility model adopts the automatic track frame of double base, it just can satisfy the function that horizontally rotates with the pitch angle adjustment with unidirectional rotation, becoming single rotation gets final product, add a weight again, make rotating turret that a driving force of rotation westwards be arranged, for slowly moving of tracking illumination photograph, also need a controlling timer, the similar clock of controlling timer, time action with pendulum, the wire rope slow slow release of lift heavy hammer is put, at this moment, weight, steel wire rope, drive, controlling timer fuses, weight also can only slowly descend, it just in time is half of drive girth that its speed is adjusted in 12 hours the length that descends, at this moment also just illumination per hour move 15 ° requirement, solar cooker also just automatically aligns sunshine tracking and rotates a whole day, till contacting to earth to weight, relocate starting next day.

Description of drawings:

The utility model is described in further detail below in conjunction with accompanying drawing:

Drive unit stereogram during Fig. 1 control that to be the utility model do in conjunction with solar cooker.

Among the figure: 1 heated kettle; 2 solar cooker reflection light-condensing surface; 3 gear frames; 4 controlling timers;

5 bracket bases; 6 rotating turrets, 7 support stay cords; The rotating shaft of 8 seasons

9 weights; Day rotating shaft in 11 times day rotating shafts 12 of 10 directive wheels

13 steel wire ropes, 14 fastening card 15 controlling timer cranks

The specific embodiment:

During installation support north and south is just put, make down day rotating shaft 11 to the south, rotating shaft 12 in last day and serve as a elevation scale between day rotating shaft and the horizon with local latitude (is 40 ° as Beijing) northwards, is not inconsistent as if the number of degrees, answers bed hedgehopping front end or rear end.The Spring Equinox, the illumination in the Autumnal Equinox just of these number of degrees is just in time perpendicular to the day rotating shaft.Putting after-poppet well should not move again.

During work, fastening card 14 is loosened, steel wire rope 13 can be slided on drive 3, hang up weight 9 and shake controlling timer handgrip 15 again, the initiatings wheel that steel wire rope 13 is wrapped in the controlling timer 4 is gone up the 8-10 circle, makes it kitchen range in the face of the fastening better fastening card 14 of Zhunyang light (or observing focus just in kettle center) with moving rotating turret 6 as the hand then, acts on during owing to the control of the pulling force of weight 9 and pendulum, kitchen range face 2 rotates together in company with drive 3 and steel wire rope 13, and weight 9 also slowly falls until till contacting to earth.

The swing of this controlling timer and the ratio of revolutions of gear are adjusted to 1/2nd girths that the length that the last steel wire rope 13 of initiating wheel was discharged at 12 hours just in time equals drive 3, just make rotating turret 12 hours change half cycle and get final product, follow the tracks of when the traveling angle speed that also just meets solar irradiation per hour is 15 ° equal speed control.When all being manufacturing, these controlling timers and drive size determined well, do not needed during use to adjust again that if little deviation is arranged, only need transferring, the speed of pendulum gets final product.

Claims

The time-controlled driving device for solar tracking is characterized by:

Utilize heavy hammer (9) to go around transmission wheel (3) and fix by steel wire rope (13), drive turret (6), the other end of steel wire rope (13) is wound on the starting wheel in the time controller, makes heavy hammer, The turret and the time controller become a linkage body to realize the automatic time control, drive and tracking device of Time and Sunshine.
