Description

Technical Field

[0001] The present invention relates to the technical field of full light energy utilization, and in particular to a lighting heat storage device and a guiding method for full light energy utilization. Background Art

[0002] The light source supply and guidance system is a system that imports light sources from the external environment into the underground environment, such as a basement or a parking lot, which can effectively save lighting energy. However, the existing light source supply and guidance system simply imports natural light (such as sunlight) from the external environment directly, and cannot maximize the effective utilization of other existing lighting. However, if all light sources are applied to the supply and guidance system, the conversion of light energy can be maximized and full light energy utilization can be achieved. However, there is no mature technology at present.

[0003] Photovoltaic panel equipment guides tracking based on the maximum intensity of light. In the prior art, the maximum instantaneous illuminance of sunlight irradiating the photovoltaic panel array is generally used as the basis for the photovoltaic panel tracking and steering. These technologies do not include the combined maximum illuminance of all light sources such as street lights, moonlight, car lights, sunlight, and light curtains, nor do they include the illuminance of invisible light (such as infrared and ultraviolet rays). As a result, the tracking system will turn too frequently, which is bound to cause unnecessary energy consumption or mechanical wear.

[0004] However, if the average value of the illuminance or sensor output voltage in a certain tracking time zone is used as the tracking steering condition of the photovoltaic panel, the optimal tracking angle of the maximum illuminance or sensor output voltage will inevitably be missed, resulting in a waste of light energy. Moreover, a delayed response can only be made after the tracking time period ends, which will inevitably cause meaningless system steering, thus losing the meaning of illuminance tracking.

[0005] In addition, if the vehicle simply uses the light intensity received by the photovoltaic panel array as a means of sensing light and making a coordinated reaction and then turning, there will also be a lag in the rotation reaction or response.

[0006] Therefore, there is an urgent need for a new lighting thermal storage device or method that does not utilize photovoltaic panels alone but rather utilizes full light energy based on tracking the maximum average illuminance within a time interval. Summary of the invention

[0052] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with specific implementation methods. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0053] The embodiment of the present invention provides a lighting heat storage device that utilizes all light energy. Figure 1 As shown, Figure 1 A schematic diagram of the principle structure of a lighting heat storage device that utilizes all light energy is provided in an embodiment of the present invention. The lighting heat storage device that utilizes all light energy includes: a controller 7, a light intensity sensor 10, a photovoltaic component 1, a light guide component 2 and a driving component 9, wherein the photovoltaic component 1 and the light guide component 2 are both assembled on the driving component 9, and the light intensity sensor 10, the photovoltaic component 1 and the driving component 9 are all electrically connected to the controller 7.

[0054] In an embodiment of the present invention, the controller 7 can be an independently set electrical control box or an intelligent terminal such as a microcomputer. The controller 7 can be installed separately. In some embodiments of the present invention, the controller 7 can also be integrated and installed on any component between the photovoltaic component 1, the light guide component 2 or the driving component 9 to reduce space occupancy.

[0055] Combination Figure 2-4 The photovoltaic assembly 1 includes an outer cover 13 and a condenser 11 arranged on the top of the outer cover 13. The outer cover 13 is a funnel structure. The inner wall of the outer cover 13 is fitted with a photovoltaic panel 12. The bottom of the outer cover 13 is provided with a light-transmitting opening, and the light-transmitting opening at the bottom of the outer cover 13 is directly opposite to the entrance position of the light guide assembly 2. The light-transmitting opening can be directly selected as an opening or a light-transmitting mirror can be arranged at the opening position; the two ends of the outer bottom of the outer cover 13 are respectively hinged on the driving assembly 9, and can be rotated under the drive of the driving assembly 9. The photovoltaic panel 12 is used to absorb the light energy scattered from the periphery and convert it into electrical energy for use.

[0056] In an embodiment of the present invention, the outer cover 13 is a multi-faceted diamond-shaped funnel structure. For the convenience of installation, the inner walls of the outer cover 13 are respectively provided with photovoltaic panels 12 to completely cover the inner walls of the outer cover 13 and absorb the scattered light source and photothermal energy as completely as possible. In other embodiments of the present invention, if an outer cover 13 with other shapes is selected, such as a circular funnel, a photovoltaic panel 12 array formed by combining multiple photovoltaic panels 12 can also be used to achieve complete coverage of the inner wall of the outer cover 13.

[0057] In the embodiment of the present invention, the bottom surface of the condenser 11 is provided with a convex surface 14 to improve the focusing effect, and the light intensity sensor 10 is arranged at the middle inner wall just below the convex surface 14 to collect the light intensity data corresponding to each orientation angle of the condenser 11 in the current environment and output it to the controller 7. In other embodiments of the present invention, the condenser 11 is a Fresnel lens structure, which not only greatly reduces the mirror thickness, but also can further improve the focusing and heat collection effects.

[0058] The controller 7 is used to obtain the illumination data fed back by the illumination sensor 10 and to adjust the orientation angle of the condenser lens 11 accordingly when the maximum illumination angle is calculated.

[0059] Specifically, during the entire process of light intensity change, for example, see Figure 5 As shown, Figure 5 The reference diagram of each interval (set period) in the tracking time interval is as follows. In a certain tracking time interval t (such as 30 minutes), after each equal time period τ (such as 1 minute), the controller 7 calculates the average illuminance (or the average output voltage U of the illuminance sensor 10) within the interval T (such as 5 minutes). avg ), so there are several average output voltages U avg , several U in the interval T avg Both are called the required value (DV) of the illuminance or sensor output voltage, that is, the average illuminance or average output voltage.

[0060]

[0061] Where U n is the corresponding illuminance (or corresponding output voltage) at any moment.

[0062] The controller 7 divides the tracking time interval t into n time periods τ, that is, t=nτ, where n is a positive integer;

[0063] At the same time, an interval segment T is defined as m adjacent time periods τ, that is, T = mτ, m is a positive integer, and t>T>τ;

[0064] Then within the tracking time interval t, there are P average illumination U avg , that is, P = n-m+1, and the intervals T corresponding to the P required values ​​are defined as S1, S2…S p , select the interval T corresponding to the maximum required value as the tracking reference, record the direction angle range of the condenser 11 in this interval, and use the direction angle range as the tracking reference. The tracking reference is used by the controller 7 to track, guide and adjust the direction angle of the condenser 11, which effectively overcomes the defect of using the average value of the entire interval and the maximum illumination at a single moment as the guiding tracking reference.

[0065] For example, if τ is 1 minute, then 10 minutes have passed, and each equal time period τ=1 minute has passed, the required value within the interval T (such as 5 minutes) is calculated 6 times in total; 20 minutes have passed, and each equal time period τ=1 minute has passed, the required value is calculated 16 times in total; 30 minutes have passed, and each equal time period τ=1 minute has passed, the required value is calculated 26 times in total, and so on, namely the intervals S1, S2, S3, S4...S26; wherein the intervals can be set to any fixed value of t>T>τ, such as t is 30 minutes, T is 5 minutes, τ is 1 minute, etc.

[0066] If the average value (i.e., required value) of each equal time period τ (e.g., 1 minute) in an interval T (e.g., 5 minutes) is calculated within a certain tracking time interval t (e.g., 30 minutes), and the unique largest required value DV is found therefrom (assuming the corresponding interval is S7), the embodiment of the present invention uses the largest required value within a certain tracking time interval t and the corresponding orientation angle range of the concentrator 11 as the guiding tracking benchmark for the photovoltaic component 1 to track the maximum illumination.

[0067] In the embodiment of the present invention, the tracking time interval t (such as 30 minutes), time period τ (such as 1 minute), and interval T (such as 5 minutes) can all be selected according to the actual accuracy requirements of the maximum illuminance. And the smaller the values ​​of the tracking time interval t, interval T, and time period τ are, the higher the utilization rate of the total light energy, the more the rotation frequency of the tracking system, and the higher the calculation speed requirements of the algorithm software. The appropriate value can be selected according to the actual application requirements, and the embodiment of the present invention has no limitation on this.

[0068] The light guide assembly 2 includes a light guide heat exchange cylinder 21 and an optical fiber light guide tube 22 arranged in the direction of the light path extension at the bottom of the light guide heat exchange cylinder 21. The upper end of the light guide heat exchange cylinder 21 faces the light transmission port at the bottom of the outer cover 13, and the light beam focused by the condenser 11 passes into the light guide heat exchange cylinder 21.

[0069] A concave lens 23 with a flat upper end and a concave lower end is provided in the middle area of ​​the light-guiding heat-exchanging tube 21. The area located at the upper end of the concave lens 23 in the light-guiding heat-exchanging tube 21 forms a heat-exchanging cavity 24. A circulating heat-absorbing medium is filled in the heat-exchanging cavity 24. The lower focal position of the convex surface 14 is located in the heat-absorbing medium in the heat-exchanging cavity 24 to absorb the heat of the light beam to increase the service life of the device. The heat-absorbing medium can be water or other media. For example, in the embodiment of the present invention, the heat-absorbing medium is water, which has the advantages of low cost and easy acquisition.

[0070] Combination Figure 6 As shown, this is a schematic diagram of the reference principle of optical transmission. Figure 6 It is only a schematic diagram of the light path. The size ratio of the convex surface 14 and the concave lens 23 can be determined according to actual needs, wherein the point f is the lower focal position of the convex surface 14. In order to achieve that the light transmitted after the light path is focused can be completely shot into the concave lens 23, so that the light directed to the optical fiber light guide 22 can be fully reflected in the optical fiber channel to avoid light loss, the lower focal position of the convex surface 14 coincides with the upper focal position of the concave lens 23. Since the convex surface 14 rotates with the condenser 11, in order to achieve an unchanged focal position of the convex surface 14, that is, in the embodiment of the present invention, the rotation axis direction of the photovoltaic module 1 coincides with the lower focal position of the convex surface 14, and the distance between the convex surface 14 and its lower focal position is the same as the distance between the concave lens 23 and its upper focal position.

[0071] In some embodiments of the present invention, the heat exchange cavity 24 is covered with a light-transmitting plate 27, and the light-transmitting plate 27 can be placed by providing a step groove (not shown) around the inner wall of the heat exchange cavity 24. The light-transmitting plate 27 can be used for light transmission and heat absorption, and at the same time can prevent the heat-absorbing medium in the heat exchange cavity 24 from overflowing. The light-transmitting plate 27 can be a graphene light-transmitting plate, which has excellent thermal conductivity, heat absorption and light transmission properties, and can absorb all light in the solar spectrum, from ultraviolet rays to infrared rays, to achieve maximum heat absorption effect; and the graphene light-transmitting plate also has extremely high strength, flexibility and light transmittance.

[0072] The optical fiber light guide 22 conducts visible light to the light outlet without loss based on the principle of total reflection of light, and the light outlet emits cold light without infrared and ultraviolet rays. In the embodiment of the present invention, the optical fiber light guide 22 is made of flexible material, and the position of the light outlet of the optical fiber light guide 22 can be adjusted according to the actual application scenario requirements, thereby realizing the adjustable lighting direction.

[0073] A dimming component 5 may also be provided at the light outlet of the optical fiber light guide 22. The dimming component 5 is electrically connected to the controller 7 to adjust the light output of the light outlet according to actual needs to improve the user experience.

[0074] In some embodiments of the present invention, an ambient light sensor may be further provided on the dimming component 5 to collect the ambient light quantity on site in real time and transmit the ambient light quantity data to the controller 7, thereby adjusting the light output of the light outlet of the dimming component 5 in real time accordingly.

[0075] An additional photovoltaic panel assembly may be provided on the side of the light outlet of the optical fiber light guide 22 to further collect the dissipated light energy and convert it into electrical energy for further utilization.

[0076] Alternatively, in some embodiments, an additional photovoltaic panel assembly can be used as a baffle to adjust the light output by blocking the light outlet position of the optical fiber light guide 22 through the photovoltaic panel assembly. This can not only further utilize the light energy, but also achieve the same adjustment function of the dimming assembly 5.

[0077] At least one water inlet 25 and at least one water outlet 26 are respectively provided in the heat exchange chamber 24, and the setting height of the water inlet 25 is greater than the setting height of the water outlet 26, so that water can enter through the water inlet 25 and flow out through the water outlet 26; in the embodiment of the present invention, the water inlet 25 and the water outlet 26 are both set as one, wherein the water inlet 25 is set at the upper end of the inner wall of the heat exchange chamber 24, and the water outlet 26 is set at the bottom of the inner wall of the heat exchange chamber 24.

[0078] The water inlet 25 is connected to a water inlet pipe 82 , and the water inlet pipe 82 is connected to an external water source. For example, the water source may be a water pipeline or a water tower in an urban environment, or may be a lake or a river in a wild environment.

[0079] The water outlet 26 is connected to a water outlet pipe 81, and the water outlet pipe 81 is used to discharge the water after absorbing heat. At this time, the water is hot water and can be collected and utilized separately.

[0080] The water inlet pipe 82 and the water outlet pipe 81 are both provided with control valves, and the control valves are electrically connected to the controller 7 to send corresponding control signals to control the flow of the water inlet pipe 82 and the water outlet pipe 81 .

[0081] The driving assembly 9 includes an upper rotating assembly 3 and a lower rotating assembly 4. The upper rotating assembly 3 is transmission-connected to the bottom of the outer cover 13 to drive the outer cover 13 to rotate; the upper rotating assembly 3 is fixedly mounted on the lower rotating assembly 4, and the lower rotating assembly 4 drives the upper rotating assembly 3 to rotate along the central axis.

[0082] The upper rotating assembly 3 includes an upper rotating motor assembly 31 and a bearing seat 32 symmetrically arranged on both sides of the outer cover 13. The two ends of the outer side of the bottom of the outer cover 13 are respectively hinged on the upper rotating motor assembly 31 and the bearing seat 32. Under the drive of the upper rotating motor assembly 31, the upper rotating motor assembly 31 can be rotated with the output end of the upper rotating motor assembly 31 as the axis. The extension direction of the output shaft of the upper rotating motor assembly 31 coincides with the lower focal position of the convex surface 14.

[0083] The lower rotating component 4 includes a rotating disk 41 and a rotating seat 42, the rotating disk 41 is rotatably arranged on the rotating seat 42, the rotating seat 42 has a built-in driving motor, the rotating disk 41 is a circular structure with a hollow middle (for light transmission), and can rotate with its center position as the axis (i.e., the central axis), the rotating seat 42 is used to drive the rotating disk 41 to rotate along the central axis, and the extension direction of the central axis coincides with the lower focal position of the convex surface 14, the upper rotating component 3 is fixedly installed on the rotating disk 41, the lower rotating component 4 is used to cooperate with the upper rotating component 3 to drive the photovoltaic component 1 to achieve tracking and guiding of the light source, and at the same time, based on the fact that the extension direction of the output shaft of the upper rotating motor component 31 coincides with the lower focal position of the convex surface 14, and the extension direction of the central axis coincides with the lower focal position of the convex surface 14, it is ensured that the photovoltaic component 1 can keep the lower focal position of the convex surface 14 unchanged when it rotates to any angle, thereby achieving the best full light energy utilization.

[0084] The lighting heat storage device utilizing all light energy further includes a support assembly 6 , on which the drive assembly 9 is assembled, and the support assembly 6 is used to provide physical support.

It can continuously provide hot water to the outside during continuous operation. On the one hand, it can simultaneously take away the heat accumulated in the light guide component 2 to increase the service life of the light guide component 2, and on the other hand, it can reuse the heat in the form of hot water, saving energy and having a good environmental protection effect.

[0087] Compared with the prior art, the lighting heat storage device utilizing all light energy described in the embodiment of the present invention has the following advantages:

[0088] 1. The illuminance data corresponding to each orientation angle of the condenser 11 in the current environment are collected by the illuminance sensor 10. According to the illuminance data, the controller 7 calculates multiple average illuminances in the tracking time interval, selects the interval corresponding to the maximum average illuminance among the average illuminances as the tracking interval, records the orientation angle range of the condenser 11 in the tracking interval, and uses the orientation angle range as the tracking reference. The tracking reference is used by the controller 7 to track and guide the orientation angle of the condenser 11, and adjust the direction of the photovoltaic module 1 accordingly, which can avoid the defect of selecting the average value of the entire interval and the maximum illuminance at a single moment as the guiding tracking reference in the prior art;

[0089] 2. The condenser 11 can irradiate the focused light beam into the light guide component 2, and use its photothermal energy to heat the water in the heat exchange cavity 24. After the graphene light-transmitting plate absorbs infrared, ultraviolet and visible light to further heat the water, the remaining visible light (cold light) is injected into the optical fiber light guide tube 22 through the concave lens 23 with the same length and focal length F as the convex surface 14, and can be used as a light source for external use after being controlled and adjusted by the dimming component 5. The heated water is collected by the water tank 8 with an inner insulation layer, and hot water can be continuously provided to the outside world, which saves energy and has a good environmental protection effect. At the same time, the heat accumulated in the light guide component 2 can be taken away synchronously, thereby increasing the service life of the light guide component 2;

[0090] 3. The extension direction of the output shaft of the upper rotating motor assembly 31 coincides with the lower focal position of the convex surface 14, and the extension direction of the central axis of the rotating disk 41 coincides with the lower focal position of the convex surface 14 when rotating, thereby ensuring that the lower focal position of the convex surface 14 can remain unchanged when the photovoltaic assembly 1 is rotated to any angle, thereby achieving optimal full light energy utilization.

[0091] On the basis of the above embodiments, the present invention further provides a method for guiding full light energy utilization, which is applied to the lighting heat storage device for full light energy utilization described in any of the above embodiments. The method for guiding full light energy utilization includes:

[0092] Collect the illumination data corresponding to each direction angle of the condenser 11 in the current environment respectively;

[0093] The tracking time interval t is divided into n time periods τ, that is, t = nτ, n is a positive integer, and an interval T is defined as m adjacent time periods τ, that is, T = mτ, m is a positive integer, and t>T>τ, then within the tracking time interval t, there are a total of P average illumination U avg , that is, P = n-m+1;

[0094] According to the illumination data, P average illuminations within the tracking time interval t are calculated, and the interval T corresponding to the maximum average illumination among the P average illuminations is selected as the tracking interval, and the orientation angle range of the condenser 11 within the tracking interval is recorded, and the orientation angle range is used as the tracking reference, and the tracking reference is used to track, guide and adjust the orientation angle of the condenser 11.
