摘要:
A sun tracker including a dual axis support for following diurnal movement of the sun and a drive mechanism for providing motive force about a first axis of the support. Accurate movement of the tracker about a second support axis is caused by a system of cables and a cooperating cable engaging arcuate surface shaped to produce the necessary movement about the second axis to maintain the tracker in appropriate orientation with the sun throughout the day. Seasonal adjustment is effected by adjusting the cable lengths.
摘要:
The known sun tracker system with helical groove guide that works according to the gravity force principle is not operational without the daily intervention of an operator, limits the weight of the solar collectors, given the muscular strength required, and thirdly makes the tracking speed dependent from the ambient temperatures, because of the temperature-dependent viscosity of the driving liquid. The disclosed tracker system has a vertical pipe, a sleeve provided with a helical groove, a guiding element, a power block that carries most of the weight of the solar assembly and rotary mast, a hydraulic energy accumulator linked by a control valve to a regulating cylinder, so that the system can be operated several days independently of outer energy sources, and a thermo- throttle that allows the rotary mast to turn at a tracking speed independent from the ambient temperature. This sun tracker system is very robust, has a relatively low energy consumption even in heavy solar assemblies and is very suitable for large-scale applications.
摘要:
A dynamic system for the utilization of solar energy which is most of the time in the ideal position in relation to the sun. Said device comprises at least one unit consisting of a solar collector and a stand carrying said collector, means for rotating the solar collector around its horizontal axis and means for rotating the solar collector and/or the stand around the vertical axis; means for simultaneous or independent actuation of the rotation means, means for the tracking control of said actuation means; and means for the transfer of the energy obtained.

The instant invention is an automatic biaxial sun tracking mechanism for use with sun ray utilization devices. Said devices are mounted on said invention, said devices forming no specific part of said invention.The invention is comprised of four principal parts: (1) a mount structure for properly positioning and supporting said sun ray utilization devices, (2) a declination shaft, (3) a polar shaft and (4) a suitable shaft-connecting means.Operation of the invention is as follows: Said shaft-connecting means is caused to rotate about the longitudinal axis of said polar shaft one revolution per day. Said shaft-connecting means is either fixed to a rotating polar shaft or rotatably connected to a fixed polar shaft. Said declination shaft is rotatably connected to said shaft-connecting means and is caused to rotate one revolution per year. The angle between two said shafts is principally determined by the maximum angular difference between the earth's equatorial plane and the sun's ecliptic plane. Said mount structure is connected by suitable means to said declination shaft. The combination of rotations about the longitudinal axes of the two said shafts results in fully biaxial (daily and seasonal) sun tracking.Provisions, in the form of partial modifications, are made for corrective compensation to the otherwise uniform drive means and for the directing of concentrated sun rays toward a remote and stationary target.
摘要:
Prior art sun-following devices exist which have an energy-storing counterweight. While this counterweight makes operation of the drive very economical, it is expensive to manufacture. The invention calls for two sun-following devices to be linked to each other in such a way that one is used as an energy-storing counterweight for the other. This gives a system with an extremely low energy consumption which leads to significant savings with large-scale systems.
摘要:
A series of inner fitted pipes with linear and helical guides or opposing helical guides for converting linear to rotational motion or converting rotational to linear motion of a support device. Hydraulics or electric screw drives are used to power the linear motion and then is converted to rotational adjustments of a directing or lifting support. This rotational support is capable of being used as a solar tracker, a robot, an exercise machine and a lift.
摘要:
The instant invention is an automatic biaxial sun tracking mechanism for use with sun ray utilization devices. Said devices are mounted on said invention, said devices forming no specific part of said invention.The invention is comprised of four principal parts: (1) a mount structure for positioning and supporting said sun ray utilization devices, (2) a polar shaft, (3) a declination crankshaft, and (4) suitable connecting members.Operation of the invention is as follows: The daily axis of said polar shaft is oriented parallel to the earth's polar axis. Said connecting members hold in a mutually perpendicular arrangement the daily axis of said polar shaft, the seasonal axis of a pivot pin for said mount structure, and the main journal axis of said declination crankshaft. Said connecting members with attached parts have suitable means to rotate about said daily axis one revolution per day. Said crankshaft has suitable means to rotate about said main journal axis one revolution per year. A suitable linkage, which simultaneously engages said crankshaft and said mount structure, serves to translate the rotary motion of said crankshaft into alternating pivotal motion of said mount structure.Modifications to the basic "direct tracking" form of the invention may be made for "indirect tracking," heavy duty crankshaft and associated parts, and corrective compensation for a variety of rotational means.
