Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cells, in particular to a performance detection device for photovoltaic cells. Background Art

[0002] With the continuous development of the photovoltaic industry, the demand for the use of photovoltaic cells is becoming more and more widespread. The manufacturing process of photovoltaic cells is constantly changing and developing rapidly. Correspondingly, the performance of photovoltaic cells is also constantly improving. Therefore, the detection and testing of photovoltaic cells is also constantly improving.

[0003] Patent announcement number CN209218043U discloses a device for detecting photovoltaic cells, including: a light source; an absorber connected to the light source, used to absorb light emitted by the light source at an angle other than a set angle to the photovoltaic cell; a reflector connected to the absorber, used to allow the light after passing through the absorber to irradiate the photovoltaic cell at a set angle to the photovoltaic cell. The patent also discloses a photovoltaic cell detection system. Since the absorber in the embodiment of the patent can absorb light emitted by the light source at an angle other than a set angle to the photovoltaic cell, it ensures that the light can pass through the reflector to irradiate the photovoltaic cell at a set angle, thereby obtaining a true photovoltaic cell detection result.

[0004] However, the device still has some shortcomings: the device ensures the accuracy of the test results through reflectors, but in the actual outdoor use of photovoltaic cells, the conversion process of visible light will be affected by the high or low temperature of the corresponding season outdoors, resulting in different results in the conversion efficiency of photovoltaic cells to visible light. Therefore, relying solely on the angle change of visible light can easily reduce the actual accuracy of photovoltaic cell performance testing. Summary of the invention

[0015] According to the above technical solution, the anti-uneven device also includes an elastic arc piece and a hollow plate, the bottom of the elastic arc piece is fixedly installed on the bottom of the inner wall of the rotating plate, the top of the elastic arc piece is in contact with the bottom of the linkage plate, the top of the hollow plate is fixedly installed on the top of the inner wall of the elastic arc piece, and the bottom of the hollow plate is in contact with the bottom of the inner wall of the rotating plate. When the linkage plate moves upward, the elastic arc piece that is limited and suppressed by the bottom of the linkage plate suddenly recovers, and the elastic arc piece will drive the hollow plate to move synchronously. Therefore, in the process of the recovery of the elastic arc piece, it will drive the hollow plate to reciprocate and knock on the bottom of the inner wall of the rotating plate to generate vibration.

Through the above cooperation, the light transmittance of the semi-arc light-transmitting plate 44 is used to ensure the purity of the light source's irradiation of the photovoltaic cell, and then the optical conversion effect of the photovoltaic cell is detected and recorded through the detection component 2. At the same time, the light source component 43 continuously changes the irradiation angle to simulate the actual outdoor lighting scene to ensure the accuracy of the detection result; through the above cooperation, the activity range of the jet component 46 is effectively expanded, the uniform coverage of cold air or heat inside the detection component 2 is accelerated, and the differences in the light source conversion performance of the photovoltaic cell at different temperatures are effectively detected.

[0035] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-stationary device 5;

[0036] The anti-stationary device 5 includes a transmission plate 51, two rotating rods 52, a sliding plate 53 and a cam 54. The top of the transmission plate 51 is hinged to the left side of the outer wall of the jet assembly 46 through a torsion spring. The tops of the two rotating rods 52 are rotatably installed on the left side of the top inner wall of the detection assembly 2.

The left side of the sliding plate 53 contacts the left side of the inner wall of the detection assembly 2. The top of the cam 54 is fixedly installed at the bottom of the rotating rod 52, and the bottom of the cam 54 contacts the bottom of the inner wall of the detection assembly 2.

[0037] The anti-static device 5 also includes a vertical plate 55, a friction plate 56, a resistance ring 57 and a plurality of rotating plates 58.

[0038] A transverse spring is arranged between the bottom of the vertical plate 55 and the bottom of the inner wall of the detection component 2, the left side of the resistance ring 57 contacts the arc surface of the outer wall of the cam 54, and a plurality of rotating plates 58 are evenly distributed on the outer wall of the rotating rod 52. A U-shaped groove is opened inside the rotating plate 58. The above cooperation effectively improves the mobility of the airflow inside the detection component 2 to prevent the airflow from gathering and being stationary, which is inconsistent with the actual flow conditions outdoors. The friction plate 56 and the vertical plate 55 drive the photovoltaic cell to continuously contact and squeeze the inner wall of the detection platform 31 to judge the strength of the photovoltaic cell itself and detect whether the performance of the photovoltaic cell changes under the influence of external interference forces, thereby further improving the comprehensiveness and accuracy of the detection data.

[0039] When in use, the jet assembly 46 moves downward in an arc trajectory, driving the transmission plate 51 to move synchronously. The bottom of the transmission plate 51 is limited by the sliding plate 53, prompting its own hinge axis to start to rotate. At this time, the transmission plate 51 starts to flip with its own hinge axis as the axis and presses the sliding plate 53 to slide downward along the outer wall of the rotating rod 52. When the sliding plate 53 slides downward, the threaded rotating rod 52 is activated to generate a rotating force. At this time, the top of the rotating rod 52 starts to rotate along the top of the inner wall of the detection component 2. The rotating rod 52 drives the cam 54 to move synchronously. When the cam 54 rotates, it breaks away from the restriction on the outer wall of the contact ring 57.

The friction plate 56 and the vertical plate 55 drive the photovoltaic cell to continuously contact and squeeze the inner wall of the detection table 31 to judge the strength of the photovoltaic cell itself and detect whether the performance of the photovoltaic cell changes under the influence of external interference forces, thereby further improving the comprehensiveness and accuracy of the detection data.

[0040] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-uneven device 6;

[0041] The anti-uneven device 6 includes a circular frame 61, a linkage plate 62, a plurality of hinged plates 63, a fixed ring 64 and a semicircular block 65. The outer wall of the circular frame 61 is slidably installed inside the U-shaped groove of the rotating plate 58, the top of the linkage plate 62 is fixedly installed at the bottom of the circular frame 61, the plurality of hinged plates 63 are symmetrical and hinged between the inner wall of the rotating plate 58 and the outer wall of the linkage plate 62, the top of the fixed ring 64 is fixedly installed on the top of the inner wall of the detection component 2, and the top of the semicircular block 65 is fixedly installed on the bottom of the fixed ring 64.

[0042] A longitudinal spring is arranged between the circular frame 61 and the rotating plate 58, and a plurality of hinged plates 63 are equidistantly distributed inside the U-shaped groove of the rotating plate 58. The top arc surface of the circular frame 61 contacts the bottom of the semicircular block 65. Through the above coordination and with the help of the reciprocating swing of the hinged plate 63, the disturbance efficiency of the rotating plate 58 on the gathered airflow is further enhanced on the original basis, that is, the dispersion rate of the airflow is further improved under the same rotation frequency, and while ensuring the fluidity of the gas, the uneven distribution of gases of different temperatures inside the detection component 2 is avoided, and the phenomenon of excessive temperature difference in some areas is prevented.

[0043] The anti-uneven device 6 also includes an elastic arc piece 66 and a hollow plate 67. The bottom of the elastic arc piece 66 is fixedly mounted on the bottom of the inner wall of the rotating plate 58, and the top of the elastic arc piece 66 contacts the bottom of the linkage plate 62. The top of the hollow plate 67 is fixedly mounted on the top of the inner wall of the elastic arc piece 66, and the bottom of the hollow plate 67 contacts the bottom of the inner wall of the rotating plate 58.

[0044] When in use, the rotating plate 58 drives the circular frame 61 to rotate when it revolves. When the circular frame 61 revolves, it breaks away from the pressure of the bottom arc surface of the semicircular block 65 limited by the fixed ring 64.

When the top arc surface of the circular frame 61 contacts the bottom arc surface of the semicircular block 65 again during the revolution, a resistance force is generated. At this time, the circular frame 61 slides downward along the inner wall of the rotating plate 58 to reset. Through the above cooperation and with the help of the reciprocating swing of the hinge plate 63, the disturbance effect of the rotating plate 58 on the gathered airflow is further enhanced on the original basis. rate, that is, the dispersion rate of the airflow is further improved under the same rotation frequency, so as to ensure the fluidity of the gas while avoiding the uneven distribution of gases of different temperatures inside the detection component 2, and prevent the temperature difference from being too large in some areas; when the linkage plate 62 moves upward, the elastic arc piece 66 suppressed by the bottom limit of the linkage plate 62 suddenly recovers, and the elastic arc piece 66 will drive the hollow plate 67 to move synchronously. Therefore, in the process of the elastic arc piece 66 recovering, it will drive the hollow plate 67 to reciprocate and knock the bottom of the inner wall of the rotating plate 58 to generate vibration. Through the above coordination, the vibration force is used to promote the rotating plate 58 to further increase the mixing speed of airflows of different temperatures during the movement, so as to avoid the adverse effects of water vapor caused by excessive temperature difference on the photovoltaic cells, and at the same time prevent the external dirt attached to the surface of the rotating plate 58 from falling off during the rotation process, thereby polluting the photovoltaic cells.
