DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the solutions of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, but not all the embodiments.

[0038] Reference is made to Figures 1 to 7As shown, the embodiment of the present application provides a photovoltaic experiment device, which comprises an experiment platform 1, a light source 2 and a sliding piece 3; the top side of the experiment platform 1 is provided with a sliding rail 11 extending along a first direction and arc-shaped light tracks 12 distributed at both ends along the first direction, the middle part of the light tracks 12 is raised along a second direction away from the experiment platform 1, and at least part of the sliding rail is located between the two ends of the light tracks 12 in the first direction; the light source 2 is slidingly connected with the light tracks 12; the sliding piece 3 is slidingly connected with the sliding rail 11 and is provided at the top end with a mounting piece 31 for mounting a photovoltaic panel 5; a control module 4 is electrically connected with the light source 2 and is provided on the mounting piece 31 with an interface for electrical connection with the photovoltaic panel 5, so that the control module 4 can collect and analyze the light intensity of the light source 2 and the power generation efficiency of the photovoltaic panel 5; the first direction and the second direction are perpendicular to each other.

[0039] Specifically, the experiment platform 1 can be selected as a rectangular metal frame, and the sliding rail 11 and the light tracks 12 are mounted on the frame. Of course, the experiment platform 1 can also be selected as a table with a desktop, and the sliding rail 11 and the light tracks 12 are mounted on the desktop. Figure 1 The arrow direction is the first direction a, the second direction b and the third direction c. The first direction a can be selected as the length direction of the experiment platform 1, the second direction b is the height direction of the experiment platform, and the third direction c is the width direction of the experiment platform.

[0040] The sliding rail 11 can be selected to include two parallel rails, and the sliding piece 3 is inserted into the space between the two rails, so that the sliding piece 3 is slidingly connected with the sliding rail 11. Of course, the top side of the sliding rail 11 can be recessed to form a sliding groove extending along the first direction a, and the bottom end of the sliding piece 3 is inserted into the sliding groove, so that the sliding piece 3 can slide in the sliding groove.

[0041] The light tracks 12 described above can be selected as an arc-shaped plate body, and the central angle corresponding to the arc-shaped plate body can be selected as 180 degrees, so that the arc-shaped plate body is semicircular. A sliding groove is recessed on one side of the light tracks 12 along the third direction c, and the sliding groove extends along the plate body. A sliding block can be selected to be slidingly connected in the sliding groove, and the light source 2 is connected with the sliding block, so that the sliding block slides along the sliding groove to drive the light source 2 to slide along the light tracks 12. Of course, the light source 2 can also be selected as a lamp panel, and one end of the lamp panel is inserted into the sliding groove, so that the lamp panel can slide along the sliding groove.

[0042] The two ends of the light tracks 12 described above can be selected to be arranged at the two ends of the sliding rail 11, so that the sliding rail 11 is located between the two ends of the light tracks 12 as a whole. Of course, the two ends of the sliding rail 11 can also exceed the two ends of the light tracks 12. The sliding rail 11 can be selected to be arranged at the side of the light tracks 12 along the third direction c. Of course, the sliding rail 11 and the light tracks 12 can also be arranged on a plane perpendicular to the third direction c.

[0043] The mounting member 31 can be a plate body rotatably connected to the top end of the sliding member 3 by a rotating shaft, which can be arranged along the third direction c, and the photovoltaic panel 5 is mounted on the top side of the plate body. Of course, the mounting member 31 can also be a bracket structure rotatably connected to the top end of the sliding member 3 by a rotating shaft, which can be arranged along the third direction c. Of course, the mounting member 31 can also be connected to the top end of the sliding member 3 by a ball hinge, so that the mounting member 31 can rotate in multiple directions relative to the sliding member 3.

[0044] The control module 4 can be a chip or a computer, and the control module 4 is electrically connected to the light source 2, so that the control module 4 can control the opening and closing of the light source 2, or further control the intensity of the light emitted by the light source 2. The control module 4 is provided with an interface on the mounting member 31, so that the photovoltaic panel 5 can be electrically connected to the joint after being mounted on the mounting plate, so that when the light source 2 irradiates the photovoltaic panel 5, the control module 4 can detect the amount of electricity generated by the photovoltaic panel 5 per unit time, thereby obtaining the power generation efficiency of the photovoltaic panel 5.

[0045] The interface can be a socket that matches the plug of the photovoltaic panel 5, and the socket is connected to the control module 4 by an electric wire. The electric wire is long and can be bent and moved, so that when the sliding member 3 slides on the sliding rail 11, the electric wire will not hinder the sliding of the sliding member 3.

[0046] The control module 4 can collect and analyze the light intensity of the light source 2 according to the power supply size of the light source 2, or a detector can be mounted on the side of the mounting member 31, and the detector is electrically connected to the control module 4. The detector can detect the light intensity irradiated on the photovoltaic panel 5. An external power supply can be provided on the experimental platform 1, and the external power supply supplies power to the control module 4. The control module 4 controls the communication and closing of the external power supply and the light source 2 to control the light source 2. Of course, the control module 4 itself can also have a battery, so that the control module 4 can supply power to the light source 2.

[0047] The light source 2 slides along the arc-shaped light irradiation track 12 to simulate the solar azimuth angle, and can simulate the movement of the sun relative to the photovoltaic panel 5 over time. The mounting member 31 rotates to adjust the angle at which the photovoltaic panel 5 receives the light emitted by the light source 2; the sliding member 3 slides on the sliding rail 11 to adjust the distance between the light source 2 and the photovoltaic panel 5, as well as the inclination angle of the light emitted by the light source 2 when it propagates to the photovoltaic panel 5, thereby adjusting the relative angle and relative position between the light emitted by the light source 2 and the photovoltaic panel 5 in multiple aspects, so that the condition when the photovoltaic panel 5 receives the light emitted by the light source 2 can be close to the actual sunlight condition.

[0048] The relative position between the photovoltaic panel and the projection lamp of the existing photovoltaic power generation experiment table is fixed. By rotating the photovoltaic panel, only the included angle between the light emitted by the projection lamp and the photovoltaic panel in the fixed direction can be changed. The simulation condition is similar to the receiving condition of the photovoltaic panel to sunlight at a moment in actual use. However, in actual use, the sun moves relative to the photovoltaic panel over time, so that the existing photovoltaic panel is difficult to simulate the power generation efficiency of the photovoltaic panel when the actual position of the sun changes. In addition, the illumination angle of the sun and the earth is different under different geographical latitude and longitude, and different installation height also affects the sunlight receiving condition of the photovoltaic panel. Therefore, the existing photovoltaic power generation experiment table has great limitations in simulating the sunlight condition, and it is difficult to meet the simulation demand of various sunlight conditions in photovoltaic power generation research, which restricts the improvement of photovoltaic power generation practical teaching quality and the in-depth development of related scientific research work.

[0049] The photovoltaic experiment device provided by the present application can adjust the illumination position of the light source 2 on the photovoltaic panel 5 on the mounting piece 31 by sliding the light source 2 along the illumination track 12. The sliding piece 3 can drive the photovoltaic panel 5 to move by sliding along the sliding track 11, so as to adjust the distance and the illumination angle between the light source 2 and the photovoltaic panel 5. The mounting piece 31 can be rotated relative to the sliding piece 3 to adjust the included angle between the light emitted by the light source 2 and the photovoltaic panel 5. The light source 2 can simulate the movement of the sun relative to the photovoltaic panel 5 by sliding along the illumination track. The sliding piece 3 can simulate the sunlight illumination angle in different latitude regions by sliding along the sliding track 11. The mounting piece 31 can adjust the most suitable installation angle of the photovoltaic panel 5 in combination with the analysis of the control module 4, so that the photovoltaic experiment device can flexibly simulate the sunlight change condition received by the photovoltaic panel under different geographical latitude and longitude conditions, and facilitate researchers to study the characteristics and rules of photovoltaic power generation. Through the linkage control of the sliding track 11, the illumination track 12, the light source 2 and the sliding piece 3, the relative position of the light source 2 and the photovoltaic panel 5, the distance and the illumination angle between the light source 2 and the photovoltaic panel 5 can be adjusted in multiple aspects. The photovoltaic experiment device can flexibly simulate the sunlight change condition received under different geographical latitude and longitude conditions, so that the photovoltaic panel 5 receives the illumination of the light source 2 more close to the actual sunlight condition, and the quality of photovoltaic power generation teaching is improved, and the in-depth development of related scientific research work is facilitated.

[0050] The photovoltaic experiment device provided by the present application is used in practice. The photovoltaic panel 5 is installed on the mounting piece 31. The relative position of the light source 2 and the photovoltaic panel 5 is determined according to the simulated sunlight environment. The position of the light source 2 on the illumination track 12 is adjusted, the position of the sliding piece 3 on the sliding track 11 is adjusted, and the mounting piece 31 is rotated to adjust the included angle between the photovoltaic panel 5 and the experiment platform 1. After the operation of adjusting the relative position of the light source 2 and the photovoltaic panel 5 is completed, the control module 4 starts the light source 2, and receives and analyzes the illumination intensity of the light source 2 and the power generation efficiency of the photovoltaic panel 5 under the illumination intensity.

[0051] Referring to Figures 1 to 3 As shown in FIG. 1, in some embodiments, the light track 12 is arranged at the side of the sliding track 11 along the third direction, the light source 2 comprises a lamp panel, the lamp panel extends along the third direction and is slidingly connected with the light track 12, so that the lamp panel is arranged opposite to the sliding track 11 along the second direction, and the third direction is perpendicular to the first direction and the second direction. In this way, the light track 12 and the sliding track 11 are staggered with each other, avoiding interference between the light track 12 and the sliding track 11 during installation and use; the lamp panel can be located above the sliding track 11 along the second direction b, ensuring that the light emitted by the lamp panel can irradiate the photovoltaic panel 5 on the sliding member 3. The extension of the lamp panel along the third direction c can increase the light coverage area, ensuring uniform light irradiation on the entire area of the photovoltaic panel 5.

[0052] Specifically, the light track 12 is arranged at the side of the sliding track 11 along the third direction c, so that the light track 12 does not limit the length of the sliding track 11, and interference between the light track 12 and the sliding track 11 is avoided. The lamp panel has a base plate, the base plate is slidingly connected with the light track 12, and the base plate extends along the third direction c, so that the base plate extends directly above the third direction c, and a bulb is arranged on the side of the lamp panel facing the sliding track 11. When the lamp panel slides on the light track 12, the base plate rotates relative to the experimental platform 1 along with the curvature of the light track 12, so that the bulb can emit light towards the sliding track 11 when the bulb is on the light track 12. The lamp panel is located directly above the sliding track 11 along the second direction b, so that the light emitted by the lamp panel can propagate towards the sliding track 11 along the radial direction of the light track 12, facilitating simulation of the actual sunlight irradiation on the photovoltaic panel 5.

[0053] Referring to Figures 1 to 3 As shown in FIG. 1, in some embodiments, the number of light tracks 12 is two, the two light tracks 12 are arranged along the third direction, the sliding track 11 is arranged between the two light tracks 12, and the two ends of the lamp panel are slidingly connected with the two light tracks 12, respectively. In this way, the two light tracks 12 can jointly support the lamp panel, enhancing the stability of the lamp panel during movement; and the two ends of the lamp panel can be supported, preventing the lamp panel from bending or deviating during movement when the length of the lamp panel is relatively long.

[0054] Specifically, the two light tracks 12 are arranged at intervals along the third direction c, the sliding track 11 is arranged between the two light tracks 12, and the two ends of the lamp panel along the third direction c can be provided with rollers, and the rollers at the two ends are synchronously clamped into the sliding grooves of the two light tracks 12. Of course, the light tracks 12 can also be provided with sliding blocks, and the two sliding blocks are arranged opposite to each other along the third direction c, and the two ends of the light panel are connected with the two sliding blocks, respectively.

[0055] Referring to Figure 5 and Figure 6As shown in the drawings, in some embodiments, the first driving member 111 is connected between the light source 2 and the light track 12, and drives the light source 2 to slide along the light track 12. The first driving member 111 is electrically connected with the control module 4, so that the control module 4 controls the start and stop of the first driving member 111.

[0056] In this way, the control module 4 can realize the automatic positioning of the light source 2 by controlling the first driving member 111, thereby improving the automation degree of the photovoltaic experimental device.

[0057] Specifically, the first driving member 111 is electrically connected with the control module 4, so that the control module 4 can control the start and stop of the first driving member 111, thereby enabling the control module 4 to drive the light source 2 to slide along the light track 12. The control module 4 can be electrically connected with the first driving member 111 through a wire, or the first driving member 111 can be a motor with a wireless module, so that the control module 4 is wirelessly connected with the first driving member 111.

[0058] The first driving member 111 can include a rotating motor, a driving gear 113, and an arc-shaped gear rack 114. The rotating motor is installed at the rotating end of the driving gear 113, and the arc-shaped gear rack 114 is welded on the light track 12. The arc-shaped gear rack 114 can be arranged on the inner wall of the sliding groove of the light track 12, or can be arranged on the outer side of the light track 12. The driving gear 113 is in meshing connection with the arc-shaped gear rack 114. The rotating motor is installed on the light source 2, receives signals from the control module 4, and drives the driving gear 113 to rotate, thereby driving the light source 2 to move along the light track 12.

[0059] Alternatively, the first driving member 111 can include a telescopic motor. The telescopic motor is rotatably connected to one end of the light track 12, and the telescopic end of the telescopic motor is rotatably connected with the light source 2. The extension and retraction of the telescopic end of the telescopic motor can drive the light source 2 to slide along the light track 12.

[0060] Referring to Figure 5 and Figure 6 As shown in the drawings, in some embodiments, the first driving member 111 includes a first motor 112, a driving gear 113, and an arc-shaped gear rack 114. The arc-shaped gear rack 114 is arranged on the light track 12, and the arc of the arc-shaped gear rack 114 is the same as that of the light track 12. The first motor 112 is installed on the light source 2, and has a first output end capable of rotating. The driving gear 113 is fixed on the first output end, and is in meshing connection with the arc-shaped gear rack 114. The first motor 112 is electrically connected with the control module 4.

[0061] In this way, the driving structure of the gear and the rack meshing connection can accurately control the moving distance, so that the control module 4 can accurately control the position of the light source 2 on the light track 12 by controlling the first motor 112, thereby facilitating the accurate adjustment of the relative position of the light source 2 and the photovoltaic panel 5.

[0062] Specifically, the first motor 112 can be a stepper motor, the first output end is the rotating shaft of the first motor 112, and the curvature radius of the arc-shaped rack 114 is strictly consistent with that of the light track 12. The driving gear 113 is connected with the rotating shaft of the first motor 112, and the driving gear 113 is meshed with the arc-shaped rack 114. When the first motor 112 drives the driving gear 113 on the rotating shaft to rotate, the driving gear 113 and the arc-shaped rack 114 can cooperate with each other to provide a force along the light track 12 to the light source 2, so that the light source 2 slides along the light track 12.

[0063] The control module 4 can control the start and stop of the first motor 112. The control module 4 can control the power supply of the external power supply to the first motor 112, or the control module 4 can have a battery, and the control module 4 controls the power supply to the first motor 112 to control the start and stop of the first motor 112.

[0064] Referring to Figures 1 to 3 and Figure 7 In some embodiments, the second driving member 121 is connected between the sliding track 11 and the mounting member 31, and the second driving member 121 can drive the mounting member 31 to rotate relative to the sliding member 3. The second driving member 121 is electrically connected with the control module 4, so that the control module 4 can control the start and stop of the second driving member 121.

[0065] In this way, the control module 4 can automatically adjust the distance between the light source 2 and the sliding member 3 by controlling the second driving member 121, thereby improving the automation degree of the photovoltaic experimental device.

[0066] Specifically, the second driving member 121 is electrically connected with the control module 4, so that the control module 4 can control the start and stop of the second driving member 121, thereby enabling the control module 4 to drive the sliding member 3 to slide along the sliding track 11. The control module 4 can be connected with the second driving member 121 through a wire, or the second driving member 121 can be a motor with a wireless module, so that the control module 4 is wirelessly connected with the second driving member 121.

[0067] The first driving member 111 can be a servo motor and a linear rack. The output end of the servo motor is rotatable, and a gear is arranged on the output end, the gear is engaged with the linear rack, the linear rack extends along the first direction a and is installed on the sliding rail 11 or the side of the sliding rail 11; the output end of the servo motor drives the gear to rotate, and the gear interacts with the linear rack to drive the sliding member 3 to slide along the sliding rail 11.

[0068] Of course, the second driving member 121 can also be a telescopic motor, which is connected to one end of the sliding rail 11. The telescopic end of the telescopic motor can extend and retract along the first direction a. The telescopic end of the telescopic motor is connected to the sliding member 3, so that when the telescopic end of the telescopic motor extends and retracts, an acting force is applied to the sliding member 3 to drive the sliding member 3 to slide along the sliding rail 11.

[0069] Referring to FIGS. 1, 2 and 3, Figures 1 to 3 and Figure 7 In some embodiments, the second driving member 121 includes a second motor 122, a rotating gear 123 and a linear rack 124. The linear rack 124 extends along the first direction and is connected to the sliding rail 11. The second motor 122 has a second output end that is rotatable. The rotating gear 123 is arranged on the second output end and is engaged with the linear rack 124. The second motor 122 is electrically connected to the control module 4. In this way, the driving structure of the gear and the rack can accurately control the movement distance, so that the control module 4 can accurately control the position of the sliding member 3 on the sliding rail 11 by controlling the first motor 112, thereby facilitating accurate adjustment of the relative position of the light source 2 and the photovoltaic panel 5.

[0070] Specifically, the second motor 122 can be a stepper motor, the second output end is the rotating shaft of the second motor 122, the linear rack 124 extends along the first direction a, and the rotating gear 123 is connected to the rotating shaft of the second motor 122.
