Description

Technical Field

[0001] The utility model relates to the technical field of landscape science, and particularly relates to a solar trajectory display device. Background Art

[0002] The sundial originally refers to the sun's shadow, and is a device that uses the position of the sun to measure time. It mainly consists of an indicator that projects the sun's shadow, a projection surface (i.e., the sundial surface) that bears the indicator projection, and scale lines on the sundial surface. The most common design, that is, the most ordinary one, is the so-called garden sundial, which makes the sun's shadow project onto a plane marked with time. When the sun moves, the time indicated by the shadow will also change. In fact, the sundial can be designed on the surface of any object, and a fixed pointer is used to generate a shadow to measure time. Therefore, there are many different forms of sundials: such as horizontal sundials, equatorial sundials, meridian sundials, and east-west sundials, etc.

[0003] The traditional sundial has the following technical problems:

[0004] At the moment of projection, it can only display the current irradiation direction of the sun, and cannot dynamically display the solar trajectory more or less, making it difficult to vividly display the movement law of the sun. People cannot quickly understand the movement direction of the sun through this projection. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a solar trajectory display device and a display method, which can dynamically display the solar trajectory more or less and vividly display the movement law of the sun.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A solar trajectory display device includes a plurality of densely arranged solar units;

[0008] Each solar unit includes a vertically arranged housing, a photovoltaic panel with a black upper surface, and a driving device;

[0009] The housing is a cylindrical structure with a light-colored inner wall, and both the photovoltaic panel and the driving device are arranged inside the housing;

[0010] The photovoltaic panel is connected to the driving device, used to provide electrical energy for the driving device, and under the drive of the driving device, it moves up and down inside the housing;

[0011] Among them, the solar unit has an initial condition and an excited condition. In the initial condition, the driving device lacks power, so that the photovoltaic panel is at the upper end of the housing to cover the light-colored inner wall of the housing; in the excited condition, the driving device is powered on, driving the photovoltaic panel to move downward inside the housing to expose the light-colored inner wall of the housing.

[0012] Further, the driving device includes an upper limit plate, a lower limit plate, a spring piece, a central column, and an electromagnet coil disposed inside the housing. The upper limit plate is disposed between the photovoltaic panel and the lower limit plate. Both ends of the central column are fixedly connected to the photovoltaic panel and the lower limit plate respectively. Both ends of the spring piece are fixedly connected to the upper limit plate and the lower limit plate respectively. The spring piece is in a bent and deformed state, and its middle part elastically abuts against the inner wall of the housing. The electromagnet coil is fixedly connected to the middle part of the central column and is electrically connected to the photovoltaic panel. The electromagnet coil and the middle part of the spring piece are correspondingly arranged with a gap therebetween.

[0013] Further, a vertically extending groove is provided on the inner wall of the housing, and the spring piece is clamped in the groove.

[0014] Further, there are multiple spring pieces and multiple electromagnet coils. The multiple spring pieces are evenly arranged around the central column, and the multiple spring pieces and the multiple electromagnet coils are correspondingly arranged one by one.

[0015] Further, the sunlight exposure unit further includes a base and a support rod. The base is disposed below the housing and is connected to the housing through the support rod. A space is left between the base and the housing to allow the middle part of the spring piece to move downward out of the housing.

[0016] Further, a reset dial is provided on the lower limit plate, and the reset dial protrudes beyond the outer edge of the housing.

[0017] A sunlight exposure trajectory display method, using the above-mentioned sunlight exposure trajectory display device, includes the following steps.

[0018] When the photovoltaic panel is not exposed to sunlight, the photovoltaic panel cannot supply power to the driving device. The sunlight exposure unit is in the initial working condition. The lack of power in the driving device causes the photovoltaic panel to be at the upper end of the housing and cover the light-colored inner wall of the housing. At this time, the main color of the sunlight exposure unit is the black upper surface of the photovoltaic panel.

[0019] When the photovoltaic panel is exposed to sunlight, the photovoltaic panel supplies power to the driving device. The sunlight exposure unit is in the excited working condition. After the driving device is powered on, it drives the photovoltaic panel to move downward in the housing, thereby exposing the light-colored inner wall of the housing. At this time, the main color of the sunlight exposure unit changes to the light-colored inner wall of the housing.

[0020] A sunlight exposure demarcation line is formed by multiple sunlight exposure units with the change of the main color connected in sequence, and the sunlight exposure trajectory is displayed.

[0021] Further, the way for the photovoltaic panel to be at the upper end of the housing is that the spring piece is in a bent and deformed state, and its middle part elastically abuts against the inner wall of the housing, so as to keep the driving device stationary in the housing and the photovoltaic panel at the upper end of the housing.

[0022] Further, the implementation method for the photovoltaic panel to move downward in the housing includes: when the photovoltaic panel is directly irradiated by sunlight, power is supplied to the electromagnet coil, the electromagnet attracts the middle part of the spring piece, the middle part of the spring piece moves towards the central column and disengages from the contact with the inner wall of the housing, so that the photovoltaic panel and the driving device move downward in the housing due to gravity.

[0023] Further, it also includes the reset step of the driving device. The reset piece on the lower limit plate is toggled upward to lift the driving device upward in the housing until the photovoltaic panel rises to the top of the housing and the spring piece abuts against the inner wall of the housing again.

[0024] Generally speaking, the present utility model has the following advantages:

[0025] The photovoltaic panel of the present utility model has both a power supply function and a collaborative color switching function. When the photovoltaic panel is not irradiated by sunlight, the driving device lacks power, causing the photovoltaic panel to stay at the upper end of the housing, and the black upper surface of the photovoltaic panel presents as the main color of the sunlight receiving unit; when the photovoltaic panel is irradiated by sunlight, power is supplied to the driving device, and the driving device drives the photovoltaic panel to move downward, so that the exposed light-colored inner wall of the housing presents as the main color of the sunlight receiving unit. By sequentially connecting multiple sunlight receiving units with the change of the main color, a sunlight dividing line is formed. Among the densely arranged multiple sunlight receiving units, on both sides of the sunlight dividing line are the black sunlight receiving units not irradiated by sunlight and the light-colored sunlight receiving units already irradiated by sunlight, so as to be able to display the sunlight track more dynamically and vividly show the movement law of the sun.

[0034] The following will further elaborate on the present utility model in detail.

[0035] As Figures 1-4 shown, a solar trajectory display device includes a plurality of densely arranged solar units laid out flat in a site, and the placement height of the solar units is less than the eye height of a person standing.

[0036] Each solar unit includes a vertically arranged housing 1, a photovoltaic panel 6 with a black upper surface, and a driving device.

[0037] The housing 1 is a cylindrical structure with a light - colored inner wall, and its color should form a strong contrast with black. Preferably, the light - colored inner wall is a white inner wall. The photovoltaic panel 6 and the driving device are both arranged inside the housing 1.

[0038] The photovoltaic panel 6 is electrically connected to the driving device, used to provide electrical energy for the driving device, and under the drive of the driving device, it moves up and down inside the housing 1.

[0039] Among them, the solar unit has an initial condition and an excited condition. In the initial condition, the driving device is out of power, making the photovoltaic panel 6 located at the upper end of the housing 1 to cover the light - colored inner wall of the housing 1. In the excited condition, the driving device is powered on, driving the photovoltaic panel 6 to move downward inside the housing 1 to expose the light - colored inner wall of the housing 1. When the photovoltaic panel 6 with a black upper surface moves downward inside the housing 1, when an observer stands in the site and looks from an oblique upper direction, the main color of the solar unit will switch from the original black of the photovoltaic panel 6 to the white of the inner wall of the housing 1. Since a plurality of solar units are regularly and densely arranged on the site, the observer can easily see which solar units have been directly irradiated by sunlight. Therefore, the movement trajectory of sunlight can be seen through these solar units with color changes.

[0040] In this embodiment, the driving device includes an upper limit plate 81, a lower limit plate 82, a spring piece 4, a central column 83, and an electromagnet coil 3 arranged inside the housing 1. Both the upper limit plate 81 and the lower limit plate 82 are circular and their diameters are smaller than the inner diameter of the housing 1, and they can move up and down inside the housing 1.

[0041] The photovoltaic panel 6 is installed on a bracket 61. Both ends of the central column 83 are fixedly connected to the middle parts of the bracket 61 and the lower limit plate 82 respectively. The upper limit plate 81 is arranged between the photovoltaic panel 6 and the lower limit plate 82. Both ends of the spring piece 4 are fixedly connected to the edges of the upper limit plate 81 and the lower limit plate 82 respectively. The spring piece 4 is in a bent - deformed state and its middle part elastically abuts against the inner wall of the housing 1 through its own elastic force, so that the driving device is stuck inside the housing 1 to keep still, and the photovoltaic panel 6 is flush with or protrudes from the upper end of the housing 1.

[0042] The electromagnet coil 3 is fixed to the middle of the center column 83 and electrically connected to the photovoltaic panel 6, which is powered by solar energy. The electromagnet coil 3 is arranged corresponding to the middle of the spring sheet 4 with a gap between them. Figure 5 As shown, when the photovoltaic panel 6 is exposed to direct sunlight and the current generated reaches a set threshold, the electromagnet coil 3 in the circuit is activated, and the electromagnet generates a magnetic field to attract the spring piece 4. Since there is a gap between the electromagnet coil 3 and the middle of the spring piece 4, the middle of the spring piece 4 moves toward the electromagnet coil 3, breaking away from the contact with the inner wall of the shell 1, causing the photovoltaic panel 6 together with the driving device to fall into the cylinder of the sunshade unit, thereby exposing the light-colored inner wall of the shell 1.

[0043] In order to make the driving device respond quickly to the sunlight of the photovoltaic panel 6, a driving battery can also be additionally provided for the electromagnetic coil 3, and the smaller current generated by the photovoltaic panel 6 can be used for triggering.

[0044] The inner wall of the housing 1 is provided with a vertically extending groove, into which the spring piece 4 is snapped. With this structure, the spring piece 4 can remain in a vertical state, which can keep the photovoltaic panel 6 above flat and will not affect the visual perception of the entire sunlight unit.

[0045] Preferably, multiple springs 4 and multiple electromagnet coils 3 are provided, and the multiple springs 4 are evenly arranged around the central column 83, with the multiple springs 4 and multiple electromagnet coils 3 arranged in a one-to-one correspondence. With this structure, the drive device is more balanced, capable of attracting springs 4 in different orientations. When multiple springs 4 are attracted simultaneously, the overall downward movement of the drive device is smoother and less likely to become stuck in the housing 1, facilitating the normal display of the sunlight trajectory.

[0046] In order to prevent the photovoltaic panel 6 from accidentally rising to the top of the shell 1 after moving down in the shell 1 and disrupting the normal display of the sunlight track, in this embodiment, the sunlight unit also includes a base 7 and a support rod 2. The base 7 is arranged below the shell 1 and is connected to the shell 1 through the support rod 2. A space is left between the base 7 and the shell 1 to allow the middle part of the spring sheet 4 to move down and out of the shell 1. When the lower limit plate 82 of the driving device falls onto the base 7, the middle part of the spring sheet 4 moves down and out below the shell 1. Since the photovoltaic panel 6 is no longer exposed to sunlight, the spring sheet 4 returns to its initial state after the electromagnet coil 3 loses power. The middle part of the spring sheet 4 arches outward again, and the outer diameter of the protruding middle part will be larger than the inner diameter of the shell 1. Without applying a large external force, it will not be able to enter the shell 1, thereby preventing the photovoltaic panel 6 from accidentally rising to the top of the shell 1 and disrupting the normal display of the sunlight track.

[0047] To facilitate the reuse of the sunlight unit, in this embodiment, a reset tab 5 is provided on the lower limit plate 82. The reset tab 5 protrudes beyond the outer edge of the housing 1, facilitating the toggling of the reset tab 5. When reset is required, the reset tab 5 on the lower limit plate 82 is toggled upward, lifting the driving device upward within the housing 1 until the photovoltaic panel 6 rises to the top of the housing 1 and the spring piece 4 abuts against the inner wall of the housing 1 again.

[0048] A sunlight trajectory display method, using the above-mentioned sunlight trajectory display device, includes the following steps.

[0049] When the photovoltaic panel 6 is not exposed to sunlight, the photovoltaic panel 6 cannot supply power to the driving device, and the sunlight unit is in the initial working condition. The lack of power in the driving device causes the photovoltaic panel 6 to be at the upper end of the housing 1 and cover the light-colored inner wall of the housing 1. At this time, the main color of the sunlight unit is the black upper surface of the photovoltaic panel 6.

[0050] When the photovoltaic panel 6 is exposed to sunlight, the photovoltaic panel 6 supplies power to the driving device, and the sunlight unit is in the excited working condition. After the driving device is powered on, it drives the photovoltaic panel 6 to move downward within the housing 1, thereby exposing the light-colored inner wall of the housing 1. At this time, the main color of the sunlight unit changes to the light-colored inner wall of the housing 1.

[0051] By connecting multiple sunlight units where the main color changes in sequence, a sunlight demarcation line is formed. Among the densely arranged multiple sunlight units, on both sides of the sunlight demarcation line are the black sunlight units not exposed to sunlight and the light-colored sunlight units that have been exposed to sunlight, thus being able to display the sunlight trajectory more dynamically and vividly show the movement law of the sun.

[0052] Specifically, the implementation method for the photovoltaic panel 6 to be at the upper end of the housing 1 is that the spring piece 4 is initially in a bent and deformed state and its middle part elastically abuts against the inner wall of the housing 1, thereby keeping the driving device stationary within the housing 1 and the photovoltaic panel 6 at the upper end of the housing 1.

[0053] The implementation method for the photovoltaic panel 6 to move downward within the housing 1 includes that when the photovoltaic panel 6 is directly irradiated by sunlight, solar energy is used to supply power to the electromagnet coil 3. The electromagnet attracts the middle part of the spring piece 4 to overcome the elastic force of the spring piece 4. The middle part of the spring piece 4 moves towards the central column 83 and disengages from the contact with the inner wall of the housing 1, causing the photovoltaic panel 6 and the driving device to move downward within the housing 1 due to gravity.

[0054] It also includes the reset step of the driving device. The reset tab 5 on the lower limit plate 82 is toggled upward, lifting the driving device upward within the housing 1 until the photovoltaic panel 6 rises to the top of the housing 1 and the spring piece 4 abuts against the inner wall of the housing 1 again.

[0055] In the sunlight trajectory display device of the present application, the sunlight unit directly irradiated by sunlight will change from the initial working condition to the excited working condition, thus playing a role similar to that of a "display pixel". The smaller the area of the sunlight unit and the denser the arrangement, the higher the display accuracy. When the sunlight units are regularly and densely arranged on the site, an observer can easily tell which places have been directly irradiated by sunlight, and thus can see the movement trajectory of sunlight. At night, the reset paddle 5 can be used to reset the sunlight units to the initial working condition for continued use the next day.

[0056] As Figure 6 shown, when the sunlight trajectory display device is laid flat in the central courtyard of an earth building, by pre-calibrating the reference lines and scales, which reference line the sun trajectory is approximately tangent to indicates which season it is today; which scale interval of the reference line the real-time trajectory of the sun moves to indicates which hour it is today. Since the north side of the site will always be irradiated by sunlight regardless of the season and hour, the sunlight units do not have to cover the entire site and can be laid out in a semicircle or crescent shape according to actual needs, taking care of other functions of the site itself. Any building with a courtyard can adopt this method to create a sundial landscape and then read the season and hour through the sunlight trajectory.

[0057] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
