Definitions

• This invention relates to a solar collector mechanism that converts the energy collected from sun rays to heat energy with high efficiency and further uses this energy to heat the fluid flowing inside the collector to high temperatures, and is also concerned with the utilization of the hot fluid obtained for hot steam production and utilization of this steam in cooling.
• a conductive surface having adequate size is used on the southern side of a building for collecting solar energy and thermal mass is utilised for absorption, storage and transmission of heat. Heat energy converted from sun rays is used for hot water production.
• Solar energy systems apart from meeting the residential hot water demand, also decrease the fuel costs by being integrated on boiler systems that produce hot water and steam which are required in industries.
• the known solar collectors are in a straight or concave forai and their surfaces that face the sun are dark colored for the purpose of absorbing more rays. Liquid that is desired to be heated is located just behind the ray absorbent layer and thus heated.
• Another known solar collector operates in principle by reflecting sun rays and the passing liquid to be heated from where it is reflected. In order to benefit utmost from sun rays, moveable collectors are also utilized.
• United States patents US4175391 and US4000734 describe two concave collectors that are connected parallel to each other. Although they do have the ability to move in order to benefit more from sun rays, only if one of them moves, the other does the same movement since these two collectors are connected parallel to each other. Under the circumstances, ray received vertically by one of them would not be received as vertical by the other; thus second collector can benefit from the rays less.
• Solar collector mechanism the subject of invention, comprises at least one solar collector that converts sun rays into heat energy by reflecting sun rays which are successively superposed at a certain region, at least one motion system (3) which provides rotation of the solar collector around one axis in order to constantly receive sun rays vertically, a heat transmission system (4) that transmits the fluid heated by the solar collector to be used in cooling and heating processes.
• a heat transmission system (4) that transmits the fluid heated by the solar collector to be used in cooling and heating processes.
• the purpose of this invention is to realize a solar collector mechanism, the movement of which is controlled by triggering with a computer software and solar sensor.
• Another purpose of this invention is to achieve the movement of more than one collector with the same motor power in a way that they would receive sunlight vertically.
• Another purpose of the invention is to realize a solar collector mechanism that provides the utilization of heat energy converted from solar energy for both heating and cooling purposes.
• Fig 1 is a perspective representation of a solar collector mechanism
• Fig 2 is a schematic representation of a solar collector mechanism
• Fig 3 is a perspective representation of a solar collector mechanism that is in stand-by (sleeping) mode
• Fig 4 is a frontal cross sectional representation of the motion system
• Fig 5 is a lateral cross sectional representation of the motion system
• Components illustrated on the drawings are numbered individually and listed below.
• Solar collector mechanism (1) the subject of invention, comprises at least one motion system (3), at least one solar collector (2) which is controlled by the motion system (3), heat transmission system (4) which transmits the fluid heated by collectors.
• the mechanism illustrated in Figure 1 is the preferred application of the invention.
• more than one solar collector (2) are located in rows as they are connected in series to each other. Each row is placed preferably parallel to the other and behind one another. Collectors in each row are connected to each other via a motion system (3) or a connector (2.2). Thus, with the aid of the connector, all collectors in each row can change their location against the sun concurrently with a single motion system.
• Solar collector (2) would comprise at least one reflector (2.1) for reflecting the received sun rays, at least one connector (2.2) that would connect collectors (2) in series to each other enabling the collective movement of two solar collectors together, at least one torsion tube (2.4) located fixed behind the collector and would prevent solar collector against torsion, a framework (2.3) made of a solid material such as iron which would enable a balanced setting on the ground and connect all the components forming the collector mechanism (1) to each other in order to enable the functionality of each component.
• Reflector (2.1) is a plate which is painted or covered with a chemical substance that has reflecting property in order to provide the reflection of received rays.
• a second plate which has reflection property, having a very thin and solid structure and which is covered with a chemical substance, is fixed on the plate which forms the shape of the reflector.
• the plate is made of metal or a material with similar solid nature and inclining the plate to a concave forai is preferred.
• the cross section of the plate has a parabolic form.
• the reflector's (2.1) arms with parabolic form are located on framework (2.3) extending towards the sun.
• the dimension of the reflector (2.1) can be modified based on the area of application.
• the pipe (4.1) that contains the fluid which is desired to be heated is carried by holders (4.6) that are fixed on the solar collector and is passed over the focal point of the parabolic reflector. Due to -the • reason that the sun rays received by the reflectors are reflected and transferred through the focal point, it is preferred that the pipe (4.1) be situated on the focal point in order to encounter more rays.
• the location of the pipe (4.1) does not change linearly with the solar collector due to the fact that moving the solar collector also moves the holders that are comiected, and the pipe always stays on the focal point of the reflector.
• a driving system 3.11
• at least one worm gear (3.3) that transmits the action sourced by the driving system
• a strainer such as a wire, strap, string, etc. that is transmitted by a worm gear
• at least one pulley (3.5) that enables the rotation of the strainer
• at least one secondary disc (3.2) and at least one primary disc that rotate along with the movement of the strainer a handle (3.7) that is attached to the solar collector by means of the primary disc.
• Driving system (3.11) is a computer driven system that is controlled by a software and a database that stores information on the location, time of the collector system and the position of the sun. In this database, information comprising the position of the sun within 365 days/24 hours for the region where the coordinates are given is stored. Thus, when the location information of the collector in a region is given, information on the position of the sun for that location is acquired.
• Driving system that creates movement such as motor, etc. is driven by a computer which is controlled by software which uses this information.
• a solar sensor (3.6) is located in the motion system.
• the sensor (3.6) sends signals to the driving system by detecting the angle of sun rays.
• Driving system is driven by using both the signals from the solar sensor together with the signals from the computer due to its software. Priority is given to the signals received from the sensor when two sources send signals at the same time, and sensitive adjustment of the solar collector is realized based on this signal.
• the cross sectional view of the motion system represented in Figure 4 illustrates at least two pulleys (3.5) that are fixed on the extensions of the framework (2.3).
• Motion created by the motion system is transmitted by the strainer which advances between pulleys.
• Driving system (3.8) is situated on the framework (2.3) and the outer end where motion is transferred, is connected to the worm gear.
• Worm gear (3.3) is driven by the driving system.
• the other end of the worm gear (3.3) is connected to the strainer and by the rotation of the screw, the strainer is moved.
• the direction of this translation can be from the worm gear (3.3) towards the strainer (3.4) or the opposite direction.
• Strainer (3.4) is pulled by the movement of the worm gear (3.3) towards one direction; moreover, it is pushed when moved in the opposite direction.
• Strainer (3.4) rotates by leaning on at least one secondary disc (3.2), one primary disc (3.1) and one pulley (3.5) forming the motion system (3) and is connected with the other end of the driving system.
• Primary disc (3.1) and one or more than one secondary disc (3.2) located in the motion system the cross sectional view of which is represented in Figure 4, are fixed on an extension of the framework (2.3).
• Advancing strainer revolves around the secondary disc (3.2) by leaning on it, moves toward the primary disc (3.1), revolves around the primary disc and rotates the primary disc (3.1) together with the motion, path and direction driven from the driving system. After the strainer is revolved around the primary disc, it is connected to the driving system by revolving around the other pulley and accomplishes its cycle.
• the strainer there are two secondary discs (3.2) in the mechanism. After the strainer is revolved around the primary disc, it revolves around the other secondary disc and is connected to the other pulley and the driving system. At another application of the invention, the strainer moves around two pulleys by providing connection with the worm gear (3.3) and the driving system (3.8). When the strainer accomplishes the translation movement, it is connected with the secondary disc (3.2) and causes this disc to rotate. Strainer material such as string, strap, etc. is used ' for transmitting rotation movements of the primary disc (3.1) and secondary disc (3.2) to each other. Thus, by rotating the secondary disc, primary disc rotates, and when the primary disc rotates, the handle (3.7) situated on it rotates the solar collector.
• Heat transmitting system (4) is the mechanism in which the cooling and heating processes of fluid inside the pipe that extends along the focal points of solar collectors reaching high temperature values, are realized. After the storage of fluid that comes from the solar collector, inside hot fluid tank, vaporization process of the high temperature fluid stored inside the steam generator is realized.
• Hot water is generated by heating the water pipes with saturated steam obtained and this hot water is used in devices such as radiators for heating purposes.
• water is used as fluid and hot water generated is used directly as hot water or in devices such as radiators for heating purposes.
• Cooling process can be summarized by the following steps;
• Saturated steam generated by the steam generator is transferred to the absorption cooling machine (4.4) in order to produce cold water.
• Absorption cooling machine operates in principle as the lithium bromide solution transforms into a muddy state when hot steam is introduced and the water inside the mud evaporates by consuming the heat of the medium; eventually, cooling the medium.
• the fluids circulating in the mechanism can be heated to extremely high temperatures.
• the mechanism is protected by stimulating signals that are generated by the computer that supports sensor and driving systems.
