Description

Technical Field

[0001] This invention relates to an improvement in sunshade canopy technology, belonging to the field of sunshade canopies, and particularly to an intelligent light-tracking sunshade canopy. Background Technology

[0002] Sunshade canopies are very common in various public entertainment venues and open-air sports fields. The popularity of outdoor sports venues can improve people's satisfaction with outdoor sports, freeing them from the constraints of natural conditions and greatly increasing the happiness of the users. However, existing sports field sunshade canopies can only provide simple shading and cannot adjust the canopy according to changes in time and the shift of the sun's angle, resulting in poor utilization of light energy.

[0003] Chinese patent application CN202221189387.6, filed on May 18, 2022, discloses a sunshade, specifically a wind-resistant sunshade. It includes a sunshade assembly and a pair of supports mounted on both sides of the bottom of the assembly. The sunshade assembly includes a flat plate with a front edge plate on its side. The front edge plate has an arc-shaped structure, and an inner arc plate is slidably connected to the inner end of the front edge plate, forming a triangular structure between the front edge plate and the supports. In this invention, the front edge plate protrudes along the front side of the flat plate, forming an arc-shaped structure, greatly reducing the contact area with the airflow. The triangular structure between the front edge plate and the supports utilizes the stability principle of triangles to improve the stability of the entire sunshade. Simultaneously, the inner arc plate remains slidably connected to the inner end of the front edge plate, allowing the sunshade area to be adjusted by changing the position of the arc plate through the supports, thus improving the flexibility of the entire sunshade. Although the prior art patent allows for some adjustment of the sunshade, it still does not solve the problem of the sunshade's inability to move and adjust over time, resulting in poor light energy utilization.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this invention, an intelligent light-tracking shading canopy is provided. The right end of the armature is connected to the left end of a joint. Two joints are fitted between the joint and the armature. The right ends of the two joints are connected to one end of an optical axis. The side of the optical axis is connected to the photovoltaic panel via a connector. The other end of the optical axis is connected to the rotor of a stepper motor via a bushing. While providing support for the photovoltaic panel, the optical axis achieves various movements of the photovoltaic panel through tilting and rotation. The armature on the lead screw motor moves up and down, causing the height of one side of the entire photovoltaic panel to change, thus tilting it. At the same time, the stepper motor rotates, driving the optical axis and thus causing the photovoltaic panel to twist at a small angle. The two directions work together to achieve large-angle light tracking of the photovoltaic panel. The light tracking can be adjusted according to the time. The photovoltaic panel rotates in real time according to the relative position of the sun, so that the sunlight shines directly on the photovoltaic panel, increasing the solar irradiation area of ​​the photovoltaic panel and improving the photoelectric conversion power, greatly improving the light energy utilization rate. Therefore, this design can intelligently track light and has a high light energy utilization rate.

[0022] 2. In this invention, an intelligent light-tracking shading canopy is provided. The bottom of the support plate is connected to the top of the through-piece. A light axis hole is provided on the side of the through-piece, and one end of the light axis passes through the light axis hole and connects to the through-piece. The top of the support plate is connected to the bottom of the photovoltaic panel. A photovoltaic panel fixing hole is provided on the top of the support plate. One end of a photovoltaic panel connecting screw passes through the photovoltaic panel and the photovoltaic panel fixing hole to fix the photovoltaic panel and the support plate. While providing shading, the canopy can be opened and closed as needed. In the event of sudden severe weather such as strong winds or heavy rainfall, each shading component can be folded to the sides of the canopy to reduce the wind-exposed area and prevent damage to the equipment caused by severe weather. Photovoltaic power generation can also be achieved through the photovoltaic panels on the top. Therefore, this design is easy to adjust and safe to use.

[0023] 3. In this invention, an intelligent light-tracking shading canopy includes a flat motor sleeve fitted around the outside of a stepper motor. The flat motor sleeve comprises a sleeve body and a support plate. The stepper motor is fitted into the left inner cavity of the sleeve body, and the right side of the sleeve body is connected to the left side of the support plate. Two smooth block through holes are formed on the front of the support plate, which is embedded between the two side plates. One end of a smooth block connecting screw passes through one and two smooth block through holes in sequence, rotatably connecting the support plate and the two side plates. The flat motor sleeve outside the stepper motor ensures the safety of the stepper motor and makes its movement and adjustment more convenient. Therefore, this design offers high safety and smooth movement. Attached Figure Description

[0056] The principle of this invention is explained as follows:

[0057] First, the slide rail 13 is fixedly installed on the roof, with the same inclination angle as the roof. The length of the slide rail 13 is determined according to the size of the site. The slide rail 13 is used to place the sliders 23 and the corresponding number of sunshade components X according to the installation area. Then, the electromagnet component 27 is installed in the slide rail 13 to fix the sliders 23. The end sliders 29 are fixed on the slide rail 13 to fix the sunshade components X set near the front end 132 of the slide rail 13. Then, the lead screw motor 8 is sleeved in the motor sleeve 9. The motor sleeve 9 is connected to the sliders 23 or the end sliders 29. When each slider 23 slides, it can drive the lead screw motor 8 to move along the direction of the slide rail 13. The lead screw of motor 8 is equipped with a contact plate 4, which is connected to the optical axis 16 through a joint 2. When the lead screw motor 8 rotates, it drives the contact plate 4 to move up and down, thereby driving the optical axis 16 to move. The back of the photovoltaic panel 5 is connected to the optical axis 16 through a connector 1. The stepper motor 17 is fitted with a motor sleeve 12, which is connected to a smooth block 14. The motor sleeve 12 and the smooth block 14 rotate relative to each other. When the smooth block 14 slides, it can drive the stepper motor 17 to slide. The rotor of the stepper motor 17 is connected to the optical axis 16 through a bushing 15. When the rotor rotates, it can drive the optical axis 16 to rotate, thereby causing the photovoltaic panel 5 to deflect at an angle, thus providing shading.

[0058] Example 1:

[0059] A smart tracking shading canopy includes a slide rail 13 and at least two shading canopy components X, all of which are sequentially arranged along the top of the slide rail 13. Each shading canopy component X includes a first joint 2, a second joint 3, a photovoltaic panel 5, a lead screw motor 8, and a stepper motor 17. The lead screw motor 8 is fitted inside a motor sleeve 9, and its output shaft is connected to one end of a lead screw 81. The side of the lead screw 81 is threadedly engaged with a connecting plate 4, and the right end of the connecting plate 4 is connected to the first joint 2. The left end is connected, and two joints 3 are sleeved between joint 2 and armature 4. The right end of the two joints 3 is connected to one end of the optical axis 16. The side of the optical axis 16 is connected to the photovoltaic panel 5 through connector 1. The other end of the optical axis 16 is connected to the rotor of the stepper motor 17 through bushing 15. The side of bushing 15 is connected to the optical axis 16 through optical axis pin 26. The stepper motor 17 is sleeved in the flat motor sleeve 12. The right end of the flat motor sleeve 12 is connected to the top of the smooth block 14. The bottom of the smooth block 14 is connected to the slide rail 13. The top of the awning components slides together; in all the awning components X, the motor sleeve 9 in the awning component X located near the front end 132 of the slide rail 13 is connected to the top of the end slider 29, and the bottom of the end slider 29 is fixedly connected to the top of the slide rail 13; the motor sleeve 9 in the other awning components X is connected to the top of the slider 23, and the bottom of the slider 23 is slidably connected to the top of the slide rail 13; an electromagnet component 27 is installed at the bottom of the slide rail 13 corresponding to the slider 23, so that the awning can be retracted in special circumstances. When the site is exposed to the elements, the photovoltaic panels on both sides of the roof move to the sides and stack up. The electromagnet assembly 27 on the slide rail 13 is released. The movement of the electromagnet assembly 27 between the two sliders 23 causes the smooth block 14 of the lead screw motor 8 and the stepper motor 17 to be in close contact. At the same time, the lead screw motor 8 rotates and drives the armature 4 to move upward so that the photovoltaic panel 5 is vertical. This then drives the lead screw motor 8 slider 23 of the next shading shed assembly X to move to the sides and arrange. When the stacking movement is completed, the photovoltaic panels 5 on each side are vertically arranged at the two edges of the shading shed.

[0060] In application: A corresponding number of awning components X are placed within the slide rail 13. Then, an electromagnet component 27 is installed in the slide rail 13 to fix the slider 23. An end slider 29 is fixed to the slide rail 13 to fix the awning components X positioned near the front end 132 of the slide rail 13. A lead screw motor 8 is then fitted into a motor sleeve 9. The motor sleeve 9 is connected to the slider 23 or the end slider 29. When each slider 23 slides, it drives the lead screw motor 8 to move along the slide rail 13. The lead screw of the lead screw motor 8 is equipped with a contact plate 4, which is connected via a joint 2. When the lead screw motor 8 rotates, it drives the armature plate 4 to move up and down, thereby driving the optical axis 16 to move. The back of the photovoltaic panel 5 is connected to the optical axis 16 through the connector 1. The stepper motor 17 is covered by a motor sleeve 12. The motor sleeve 12 is connected to the smooth block 14. The motor sleeve 12 and the smooth block 14 rotate relative to each other. When the smooth block 14 slides, it can drive the stepper motor 17 to slide. The rotor of the stepper motor 17 is connected to the optical axis 16 through the bushing 15. When the rotor rotates, it can drive the optical axis 16 to rotate, thereby causing the photovoltaic panel 5 to deflect at an angle, thus providing shading.

[0073] Example 5:

[0074] Example 5 is basically the same as Example 1, except that:

[0075] The calculation method for the deflection angle of the photovoltaic panels in a smart light-tracking shading canopy is as follows:

[0076] β is the slope, the angle between the surface plane and the horizontal plane; 0°≤β≤180° (β>90° indicates that the surface has a downward part). When horizontal, β=0°; when vertical, β=90°.

[0077] ω is the hour angle, which is the angular displacement of the sun east or west of the local meridian due to the Earth's rotation around its axis at a speed of 15° per hour; it is negative in the morning and positive in the afternoon.

[0078] Calculation of the hour angle ω:

[0079] 12:00 solar time is 0, morning time is negative, and afternoon time is positive.

[0080] For example:

[0081] If the solar time is 11:00 AM, then the hour angle ω = (11-12) × 15° = -15°

[0082] If the solar time is 16:30 PM, then the hour angle ω = (16.5 - 12) × 15° = 67.5°

[0083] θ, the angle of incidence, is the angle between direct radiation on a surface and the normal to that surface.

[0084] The equation relating the angle θ of direct solar radiation on a surface to other angles is as follows:

[0085] cosθ=sinδsinφcosβ-sinδcosφsinβcosγ+cosδcosφcosβcosω+cosδsinφsinβcosγcosω+cosδsinβsinγsinω

[0086] θ z Zenith angle, the angle between a vertical line and the sun, that is, the angle of incidence of direct solar radiation on a horizontal plane;

[0087] cosθ z =cosφcosδcosω+sinφsinδ

[0088] h, solar altitude angle, is the angle between the horizontal line and the sun, which is the complementary angle of the zenith angle;

[0089] The solar altitude angle h is only a function of the time of day and the angle of inclination, as shown in the following formula:

[0090] sinh=cosθ=cosθ z =cosφcosδcosω+sinφsinδ

[0091] α′, solar azimuth angle, is the angular displacement of the projection of the sun's direct radiation onto a horizontal plane from the south, such as... Figure 14As shown, displacements east of south are negative, and displacements west of south are positive, as indicated by the following formula:

[0092]

[0093]

[0094] like Figure 14 As shown, the solar constant I SC The formula for calculating the solar radiation energy received per unit area per unit time on a surface perpendicular to sunlight at the outer boundary of Earth's atmosphere when Earth is at its average distance from the Sun is as follows:

[0095] I0=ξ0I SC

[0096] ξ0: Eccentricity correction factor for Earth's orbit

[0097] I SC Solar radiation intensity at average Earth-Sun distance

[0098] Simplified calculation formula:

[0099]

[0100] Atmospheric mass m: The thickness of the atmosphere through which solar radiation passes.

[0101] Furthermore, the entire atmospheric thickness perpendicular to the sea level is defined as "one atmospheric mass", i.e., m = 1;

[0102] When the sun is not perpendicular to the sea level, the atmospheric mass *m* can be calculated using the following formula:

[0103]

[0104] Atmospheric transparency P: A parameter characterizing the transparency of the atmosphere to sunlight.

[0105] Atmospheric radiation intensity on the horizontal plane

[0106] I B =I BN sinα

[0107] Ground-level normal solar radiation intensity I BN The calculation formula is as follows:

[0108] I BN =I0P m

[0109] I B =ξ0I sc P m sinα

[0110] Solar diffuse radiation intensity I on a horizontal plane D The calculation formula is as follows:

[0111]

[0112] Total solar radiation intensity I on a horizontal plane H The calculation formula is as follows:

[0113]

[0114] like Figure 15 As shown, the tilt angle β and direction angle γ of any plane n and the angle of incidence of sunlight θ i

[0115] The intensity of direct solar radiation I on an inclined plane BT The calculation formula is as follows:

[0116]

[0117] Solar scattered radiation intensity I on the inclined plane DT The calculation formula is as follows:

[0118]

[0119] Solar reflected radiation intensity I on the inclined plane RT The calculation formula is as follows:

[0120]

[0121] ρ — Ground reflectivity

[0122] Total solar radiation intensity I on the inclined surface T

[0123]

[0124] The reflectivity of different ground and water surfaces is shown in the table below:

[0125]

[0126] Solar radiation intensity on the same day with different placement methods, such as Figure 16 As shown:

[0127] Calculations show that, under the condition of chasing sunlight, adjusting the position of photovoltaic panel 5 results in 58% more solar radiation received per unit area compared to horizontal placement and 20% more compared to fixed-angle placement.

[0128] Solar tracking accurately calculates the solar zenith angle and solar azimuth angle based on local time and latitude, and achieves intelligent solar tracking by adjusting the attitude of the solar equipment through mechanical control.

[0129] Solar zenith angle

[0130] The solar zenith angle is the angle between the direction of sunlight incident and the direction perpendicular to the zenith, ranging from 0° to 180°. Its calculation formula depends on the solar declination angle, the latitude of the target region, and the solar hour angle. The specific expression is as follows:

[0131] cosθ z =cosφcosδcosω+sinφsinδ

[0132] Sun azimuth

[0133] The formula for calculating azimuth is as follows:

[0134]

[0135]

[0136] The formula for calculating the solar declination angle is as follows:

[0137]

[0138] In the formula, n is the number of days in a year for the desired date.
