Description

Technical Field

[0001] The utility model relates to the technical field of material photothermal conversion efficiency testing, in particular to a material photothermal conversion efficiency testing platform. Background Art

[0002] Before using solar panels, the photothermal conversion efficiency of the solar panels needs to be tested. The photothermal conversion efficiency test of materials is a method of evaluating the photothermal conversion efficiency of materials by measuring their ability to absorb light energy and convert it into heat energy. During the test, a test platform is required.

[0003] The photothermal conversion efficiency test platform is an experimental device used to evaluate the ability of materials to convert light energy into heat energy under lighting conditions. In order to ensure the stability of samples during the test, the samples usually need to be fixed. However, during the fixing process, the operator cannot intuitively understand whether the samples are fixed tightly. Therefore, the samples are very likely to be loosely fixed, causing the samples to shake during the test, thereby affecting the test results. At the same time, during the fixing process, it is also very easy for the operator to use too much force, resulting in excessive force on the sample, causing the sample to crack during the fixing process. To address this problem, we proposed a material photothermal conversion efficiency test platform. Utility Model Content

[0004] The purpose of the utility model is to provide a material light-to-heat conversion efficiency testing platform to solve the problems raised in the above background technology.

[0008] A knocking piece is arranged in the support frame, and a bell makes a sound when subjected to force, thereby reminding the operator that the sample is fixed, thereby avoiding the situation where the sample is not fixed tightly.

[0009] Preferably, a through hole is provided on the surface of the fixing column, and the provision of the through hole can ensure the stable movement of the flat rod.

[0010] Preferably, the knocking member comprises: a bracket, the bracket is fixedly mounted on the inner wall of the support frame, a cross bar is fixedly mounted on the surface of the bracket, a bell is fixedly mounted on the surface of the cross bar, and when the bell is struck, a sound can be generated on the surface of the cross bar.

[0011] Compared with the prior art, the utility model provides a material light-to-heat conversion efficiency testing platform, which has the following beneficial effects:

[0012] 1. The utility model is provided with a control component. The moving plate contacts the sample to make it contact the surface of the pressure plate. The pressure plate is forced to move under the support of the spring 1 and contacts the cross section of the moving rod. The moving rod is forced to move under the support of the spring 2.

[0013] 2. The utility model is provided with a driven component, and a disc rotates on the surface of the fixed column. The disc drives the threaded rod and the pillar to rotate. During the rotation of the threaded rod, the moving block is forced to drive the flat rod and the moving plate to move.

When the pressure plate contacts the moving rod, the moving rod moves toward the fixed column under the support of spring 2, and the clamping rod is clamped into the clamping groove provided on the surface of the pillar. The rotation of the pillar and the threaded rod is limited by the clamping block. This method can not only adapt to samples of different sizes, but also avoid the situation where the operator's hand force is too large and causes damage to the sample.

During the movement, the pressure plate 71 hits the cross section of the moving rod 74. The moving rod 74 is forced to move toward the fixed column 5 under the support of spring 2 88. When the moving rod 74 moves, the sliding rod 75 fixed on the surface of the moving rod 74 moves synchronously in the annular groove 77 on the surface of the cylinder 76. The cylinder 76 is forced to drive the cam 79 to rotate. During the rotation, the bell 7103 on the surface of the cross bar 7102 can be knocked, and the bell 7103 is forced to make a sound, thereby reminding the operator that the sample is fixed, avoiding the situation of not being fixed tightly.

[0021] The surface of the fixed column 5 is provided with a through hole 6, and the provision of the through hole 6 can ensure the stable movement of the flat rod 86. The knocking member 710 includes: a bracket 7101, the bracket 7101 is fixedly mounted on the inner wall of the support frame 78, a cross bar 7102 is fixedly mounted on the surface of the bracket 7101, and a bell 7103 is fixedly mounted on the surface of the cross bar 7102.

The driven component 8 includes: a disc 81, the disc 81 is rotatably connected to the surface of the fixed column 5, the fixed column 5 is penetrated by a threaded rod 82 and is rotatably connected to the threaded rod 82, the surface of the threaded rod 82 is fixedly connected to the surface of the disc 81, and a pillar 83 is fixedly mounted on the surface of the threaded rod 82.

[0022] In the utility model, when in use, the solar panel to be tested is placed on the surface of the sensor plate 9. After placement, the disc 81 is rotated on the surface of the fixed column 5, and the disc 81 drives the threaded rod 82 and the support 83 to rotate synchronously. During the rotation of the threaded rod 82, the moving block 85 is forced to move, and the flat rod 86 fixed on the surface of the moving block 85 drives the moving plate 87 to slide on the surface of the fixed column 5 and contact the sample, so that it contacts the surface of the pressing plate 71. The pressing plate 71 is squeezed and moves under the support of the spring 1 72. During the movement of the pressing plate 71, it contacts the cross-section of the moving rod 74. The moving rod 74 is forced to move into the fixed column 5 under the support of the spring 2 88. When the moving rod 74 moves, the sliding rod 75 fixed on the surface of the moving rod 74 is in the annular groove 77 on the surface of the cylinder 76. Synchronously moving, the cylinder 76 is forced to drive the cam 79 to rotate. During the rotation, the bell 7103 on the surface of the cross bar 7102 can be knocked, and the bell 7103 makes a sound under the force, thereby reminding the operator that the sample is fixed, avoiding the situation of not being fixed tightly.

This method can not only adapt to samples of different sizes, but also avoid the situation where the operator does not hear the sound of the bell 7103 and the sample is damaged due to excessive hand strength. After fixation, turn on the strong light 2 to focus the light on the surface of the solar panel to apply a constant temperature to the solar panel sample, and the heating or cooling equipment can be used to reach the required temperature. The temperature distribution of the solar panel sample is monitored in real time using the temperature measuring device 4, and the temperature change data during the test is recorded. The light-to-heat conversion efficiency of the solar panel is calculated based on the recorded temperature change data and known parameters such as light intensity and solar panel absorptivity. The light-to-heat conversion performance of the solar panel is evaluated based on the test results, and statistical analysis and comparison of the data are performed. After the measurement is completed, the disk 81 is reversed, and the threaded rod 82 and the support 83 are reversed synchronously.
