[0001] The present subject matter relates to the field of solar heaters. In particular, the present subject matter relates to a solar water heater equipped with a solar tracking system.
[0002] Parabolic collectors (parabolic solar collector systems) are known in the art. Typically, these parabolic collectors are used to capture and use solar io energy to obtain electricity and heat from it. An example of such a typical parabolic solar collector system includes one or more long parabolic trough reflectors and thermal absorbing pipes located in the focus of the reflectors. These pipes on which the rays coming from the reflector are concentrated contain a fluid to be heated. The system may further include a rotation mechanism, which orients the reflectors in accordance with the position of the sun throughout the day to facilitate maximum reception of the solar energy thereon. The incident rays in the reflectors facing the sun are reflected and collected in the thermal absorber tube that is in the focus of the receiver for the purpose of heating the fluid contained therein.
[0003] A disadvantageous aspect, however, of the aforementioned parabolic solar collector systems is that the rotation mechanism for changing the orientation of the parabolic collectors have a complicated design and configuration. Employing such systems at rural locations may cause excessively long downtimes during maintenance procedures due to unavailability of spare components of the complicated rotation mechanisms.
[0004] This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features of essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
[0005] The present subject matter envisages a solar fluid heater system. The solar fluid heater system comprises a solar concentrator for heating the fluid, wherein the solar concentrator is configured for angular movement within a pre-defined angular range, wherein the angular movement of the solar concentrator is controlled angular movement that is variable or controllable for receiving maximum solar radiations. The system further comprises a support structure for pivotally supporting the solar concentrator thereon. The system further comprises a linkage mechanism comprising a screw jack disposed adjacent the support structure; a first link coupled to and extending vertically from screw jack, the first link configured to vertical linear reciprocation movement; and a second link coupled to the first link and the solar concentrator for facilitating motion transmission of linear reciprocation movement of the first link to the solar concentrator, thereby facilitating the controlled angular movement of the solar concentrator.
[0006] In an alternative embodiment, the solar fluid heater system further comprises a controller; and a motor communicatively coupled to the controller and mechanically coupled to the screw jack for facilitating vertical linear reciprocation movement of the first link.
[0007] In an alternative embodiment, the solar concentrator is a parabolic reflector trough having a pair of extensions extending from lateral end edges of the parabolic trough, thereby providing a top-hat configuration to the solar concentrator.
[0008] In an alternative embodiment, the solar concentrator includes a hollow fluid carrying shaft that allows the passage of a fluid to be heated therethrough; and a pair of supporting links pivotally coupled to the hollow fluid carrying shaft and mechanically coupled to the solar concentrator, wherein the solar concentrator is the parabolic reflector trough.
[0009] In an alternative embodiment, the support structure comprises a pair of bracket pillars having a spaced apart configuration, wherein the hollow fluid carrying shaft is mechanically coupled to and supported on the pair of bracket pillars.
[0010] In an alternative embodiment, the second link is an L-shaped link mechanically coupled to the hollow fluid carrying shaft.
[0011] In an alternative embodiment, the first link comprises an engagement head for engaging with the second link, wherein the engagement head includes a pair of slots configured thereon in a spaced apart configuration, wherein each slot of the pair of slots is engageable with one arm of the second link having the L-shaped configuration, thereby facilitating conversion vertical reciprocation movement of the first link into angular movement of the shaft and the solar concentrator.
[0012] In an alternative embodiment, the solar fluid heater system further comprises a plurality of photovoltaic cells mounted on each of the extensions; and a current sensor mounted on each of the extensions and coupled to the plurality of photovoltaic cells, wherein the current sensor is configured to sense the current generated by the plurality of photovoltaic cells provided on each of the extensions. In one embodiment, the current sensor is communicatively coupled to the controller. The controller is configured to activate operation of the motor until the currents sensed by the current sensors on provided on each extension of the solar concentrator are equal.
[0013] Another implementation of the solar fluid heater system, in accordance with one embodiment of the present subject matter, includes a plurality of solar concentrators arranged to form an array. Such an implementation includes one linkage mechanism disposed adjacent one solar concentrator for facilitating the controlled angular movement of the one solar concentrator. A motion transmission member extends along the array of solar concentrators and is io mechanically coupled to the solar concentrators for transmitting the controlled angular movement on the one solar concentrator to the remaining solar concentrators.
[0014] These and other features and advantages of the present subject matter will become more readily apparent from the attached drawings and the detailed description of the preferred embodiments, which follow.
[0015] The present subject matter is hereinafter described with reference to non-limiting accompanying drawing in which:
[0016] FIG. 1 and FIG. 2 illustrate isometric views of a solar fluid heater system depicting a start position and an end position of the solar fluid heater system during the course of solar tracking throughout the day, in accordance with an embodiment of the present subject matter;
[0017] FIG. 3 illustrates an exploded view of the solar fluid heater system, in accordance with an embodiment of the present subject matter; and
[0018] FIG. 4 illustrates a schematic view of a solar fluid heater system including a plurality of solar concentrators, in accordance with another embodiment of the present subject matter.
[0019] FIG. 1 and FIG. 2 illustrate isometric views of a solar fluid heater system 100 depicting a start position and an end position of the solar fluid heater system 100 during the course of solar tracking throughout the day, in accordance with an embodiment of the present subject matter. FIG. 3 illustrates an exploded isometric view of the system 100, in accordance with an io embodiment of the present subject matter. Referring is hereinafter directed to FIG. 1 through FIG. 3. The solar fluid heater system 100 (alternatively referred to as system 100) comprises a solar concentrator 102 for heating the fluid, wherein the solar concentrator is configured for angular movement within a pre-defined angular range. In accordance with an embodiment of the present subject matter, the angular movement of the solar concentrator 102 is controlled angular movement that is variable or controllable for receiving maximum solar radiations. More specifically, this controlled angular movement is the movement of the solar concentrator 102 facilitated via a solar tracking system. The solar tracking system of the present has been described in elaboration in the subsequent sections of the present disclosure.
[0020] The system 100 further comprises a support structure 104 for pivotally supporting the solar concentrator 102 thereon. The support structure 104 comprises a pair of bracket pillars 106 having a spaced apart configuration. The distance by which the bracket pillars 106 are separated decided based on the length of the solar concentrator 102 that is to be supported thereon.
[0021] The solar concentrator 102, in accordance with an embodiment of the present subject matter, includes a hollow fluid carrying shaft 108 (alternatively referred to as shaft 108) that allows the passage of a fluid to be heated therethrough. More specifically, the shaft 108 is a dual purpose component that carries in it water to be heated as well as facilitates the support of the solar concentrator 102 on the bracket pillars 106. In an embodiment, the solar concentrator 102 may be a parabolic reflector trough. A pair of supporting links 110 are pivotally coupled to the hollow fluid carrying shaft 108 and mechanically coupled to the solar concentrator 102. More specifically, the supporting links 110 are A shaped links wherein the vertex of the link is coupled to the shaft 108, whereas the ends of the two arms are connected to the parabolic collector of the solar concentrator 102. It is to be noted that the shaft 108 may be connected to a water source at one end, and a reservoir at the io other end. However, the same has not been depicted in the figures in an effort to prevent overcomplication of the figures.
[0022] As seen in FIG. 1 and FIG. 2, the hollow fluid carrying shaft 108 is mechanically coupled to and supported on the pair of bracket pillars 106. In accordance with one embodiment of the present subject matter, the support of the shaft 108 on the bracket pillars 106 is facilitated via bearings (not illustrated herein) for facilitating the pivotal motion of the shaft 108 under the influence of the solar tracking system throughout the duration of an entire day. The pivotal movement of the shaft 108 is then transmitted to the parabolic trough of the solar concentrator 102, thereby facilitating the pivotal motion of the solar concentrator 102 in accordance with the position of the sun for obtaining the most optimal position of maximum solar ray reception.
[0023] The system 100 further comprises a solar tracking system 200. The solar tracking system 200, in accordance with an embodiment of the present subject matter, is hereinafter described with reference to FIG. 1 and FIG. 2. The solar tracking system 200 comprises a linkage mechanism 202 comprising a screwjack 202A disposed adjacent the support structure, and a first link 202B coupled to and extending vertically from screw jack 202A. The first link 202B is configured for vertical linear reciprocation movement that is effected by the screwjack 202A. The solar tracking system 200 further comprises a second link 202C that is coupled to the first link 202B and the solar concentrator 102 for facilitating motion transmission of linear reciprocation movement of the first link
202B to the solar concentrator 102, thereby facilitating the controlled angular movement of the solar concentrator 102. FIG. 1 depicts the initial position of the solar concentrator 102 at the sunrise, whereas FIG. 2 depicts the final position of the solar concentrator 102 at the sunset. The change of positions of the solar concentrator 102 throughout the day is facilitated by the solar tracking system 200, in accordance with an embodiment of the present subject matter.
[0024] In accordance with an embodiment of the present subject matter, the second link 202C is an L-shaped link mechanically coupled to the hollow fluid carrying shaft 108. In one embodiment, the vertex end of the second link 202C io may be connected to the shaft 108, either by welding or any other form of mechanical coupling. As such, the arms of the second link 202C may extend outwardly from the vertex end after the second link 202C is connected to the shaft 108. The first link 202B receives and interacts with the second link 202C for facilitating the pivotal movement of the shaft 108, and thereby that of the solar concentrator 102.
[0025] In accordance with an embodiment of the present subject matter, the first link 202B comprises an engagement head 204 for engaging with the second link 202C, wherein the engagement head 204 includes a pair of slots 206 configured thereon in a spaced apart configuration, wherein each slot 206 of the pair of slots 206 is engageable with one arm of the second link 202C having the L-shaped configuration, thereby facilitating conversion vertical reciprocation movement of the first link 202B into angular movement of the shaft 108 that is coupled to the second link 202C, and thereby the solar concentrator 102. More specifically, the arms of the second link 202C are inserted within the slots 206 in an operative configuration thereof, as seen in FIG. 1 and FIG. 2. As the first link 202B reciprocates in the vertical direction, a mechanical drive is provided to the arms of the second link 202C, which facilitates the pivotal movement of the solar concentrator 102.
[0026] For a solar tracking system 200, an automatic operation of the same is of paramount importance. To this end, the solar tracking system 200 comprises a controller 208, and a motor 210 communicatively coupled to the controller 208 and mechanically coupled to the screw jack 202A for facilitating vertical linear reciprocation movement of the first link 202B. The controller 208 includes an integrated processor and memory, wherein instructions for controlling the actuation of the motor 210 are stored. An advantageous aspect of the solar tracking system 200 of the present subject matter is the simplicity and the minimal number of components involved in facilitating an optimal solar tracking movement of the solar concentrator 102.
[0027] More specifically, the solar concentrator 102 is a parabolic reflector io trough having a pair of extensions 102A extending from lateral end edges of the parabolic trough, thereby providing a top-hat configuration to the solar concentrator 102. A plurality of photovoltaic cells 212 are mounted on each of the extensions 102A. A current sensor 214 is also mounted on each of the extensions 102A and coupled to the plurality of photovoltaic cells 212, wherein the current sensor 214 is configured to sense the current generated by the plurality of photovoltaic cells 212 provided on each of the extensions 102A.
[0028] In accordance with an embodiment of the present subject matter, the current sensor 214 is communicatively coupled to the controller 208. The controller 208 is configured to activate operation of the motor 210 until the currents sensed by the current sensors 214 on provided on each extension of the solar concentrator 102 are equal. More specifically, the position of the solar concentrator 102 at which the currents produced by both the photovoltaic cells 212 is equal is most optimal position of the solar concentrator 102 for receiving maximum solar radiations thereon. As such, the motor 210 is configured to be actuated at every instant when the currents generated by the photovoltaic cells 212 are unequal, and the actuation is stopped as soon as the currents generated by the photovoltaic cells 212 are in equal rating.
[0029] Another implementation of the solar fluid heater system 300, in accordance with one embodiment of the present subject matter, is illustrated in FIG. 4. The features of the system 100 and system 300 are identical with the only difference being that system 300 includes a plurality of solar concentrators 102 arranged to form an array, whereas system 100 includes a single solar concentrator. As such, the entire description of identical elements of system 100 and system 300 is not repeated again for the sake of brevity of the present document.
[0030] Referring to FIG. 4, the system 300 comprises a motion transmission member 302 that extends along the array of solar concentrators 102 and is mechanically coupled to the solar concentrators 102 for transmitting the controlled angular movement on the one solar concentrator 102 to the io remaining solar concentrators 102. More specifically, the solar tracking system 200 is only provided adjacent to and operably coupled to one of the solar concentrators 102, and the motion transmission member 302 allows the transmission of the mechanical drive from one solar concentrator 102 that is coupled to the solar tracking system 200 to all the other remaining solar concentrators 102.
[0031] An advantageous aspect of such a configuration is that one solar tracking system 200 can be used to facilitate solar tracking of multiple solar concentrators as opposed to having a separate solar tracking system 200 for each solar concentrator 102.
[0032] An advantageous aspect of the solar tracking system 200 of the present disclosure is that it uses a very simple mechanism to facilitate the solar tracking of the system 100. More specifically, the solar tracking system 200 has a very simple design with minimal number of components that are widely available. For example, the controller, current sensors, photovoltaic cells, and so on are easily replaceable and easily available in the market.
[0033] Different characteristics and beneficial particulars are unfolded fully with reference to the embodiments/aspects, which are exemplified in the accompanying drawing and detailed in the preceding description.
