Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic component test equipment, in particular to a wet heat test equipment for solar photovoltaic components. Background Art

[0002] Solar photovoltaic modules (also called solar panels) are the core and most important part of the solar power generation system. Since single solar cells cannot be used directly as a power source, if you want to use them as a power source, you must connect several single cells in series and parallel and tightly seal them into modules. Their function is to convert solar energy into electrical energy and send it to batteries for storage or to drive the load to work.

[0003] As the global demand for renewable energy continues to grow, solar photovoltaic technology, as an important part of it, has been widely studied and applied. In order to ensure the stability and reliability of solar photovoltaic modules in various harsh environments, it is essential to conduct strict environmental adaptability tests on them. Humid and hot environments are a common environment that solar photovoltaic modules may encounter during actual use. Therefore, test equipment that can simulate this environment, that is, wet and hot test equipment for solar photovoltaic modules, is of great significance for improving the quality and performance of photovoltaic products.

[0004] The prior art publication number is CN103076549B, which provides a device and method for wet heat testing of photovoltaic modules. The wet heat testing device includes: a test box for simulating a wet heat environment, having a photovoltaic module mounting portion for mounting the photovoltaic module to be tested; a power supply, having a power supply terminal arranged inside the test box to supply power to the photovoltaic module, simulating a wet heat environment in the test box to form an outdoor extreme state of the photovoltaic module when working, and applying a continuous voltage equivalent to a solar power generation system to the photovoltaic module to simulate the working state of the photovoltaic module during the power generation process, so that the wet heat test can be completed in a short time. By comparing the power attenuation values ​​before and after the test, the quality of the photovoltaic module can be determined and the amount of power generated by the photovoltaic module can be predicted. Since the wet heat testing device of the invention has a simple structure, it is conducive to wide application in actual production.

[0005] Although the above-mentioned prior art detects the amount of electricity while undergoing the wet heat test, it is tested by turning on the power during the process. The main function of the photovoltaic module is to convert light energy into electrical energy. Therefore, the most direct way to subject it to the wet heat test and detect the electrical energy is to install a light source panel that simulates the sun in a wet heat environment, and monitor the power generation of the photovoltaic panel in the wet heat environment in real time. The light source panel is easily damaged in such a space. If damage occurs, the detection can only be interrupted, and the light panel must be re-prepared for the experiment again. The operation is cumbersome, and there is no backup equipment in the comparative document. In addition, the supporting mechanism of the photovoltaic panel in the comparative document is fixed, and the flexibility is insufficient.

[0006] It can be seen that there is a need for a wet heat test equipment for solar photovoltaic modules, which is used to improve the detection method in the comparative documents and solve the problem that the light source panel in the wet and hot space mentioned in the above background technology is easily damaged. If damage occurs, the detection can only be interrupted and the light panel must be re-prepared for the experiment again, which is cumbersome to operate. There is no spare equipment in the comparative documents, and the supporting mechanism of the photovoltaic panel in the comparative documents is fixed and lacks flexibility. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 A wet heat test equipment for solar photovoltaic components includes a test box 1, a main light panel 2 and a backup light panel 3 are respectively installed on the upper and lower sides of one side inside the test box 1, and a movable door 4 and a protective shell 401 are arranged on the outer side of the backup light panel 3.

A plurality of groups of temperature and humidity detection probes are provided inside the test box 1 for detecting the temperature and humidity in the test box 1. The main light panel 2 and the backup light panel 3 adopt the light panels simulating sunlight light sources which are more common on the market. In order to cope with the humid and hot environment, the humid and heat resistant light panels can be adopted, but this does not conflict with the backup light source in the present application, because the humid and heat resistant light panel does not mean that it will not be damaged in the humid and hot environment. The two groups of light panels in the present application are just in case, to avoid the situation where the experiment needs to be stopped immediately after the main light panel 2 is damaged.

[0026] Specifically, an installation cavity 101 is provided inside the test box 1, and an air duct cavity 102 is provided inside the installation cavity 101, a detection cavity 103 is provided inside the air duct cavity 102, a heating element is installed inside the detection cavity 103, and a ventilation duct is provided between the detection cavity 103 and the air duct cavity 102, a fan is installed inside the air duct cavity 102, a wiring channel is provided between the detection cavity 103 and the top of the test box 1, and an electric power detection device is installed at the top of the test box 1.

If the light panel and the photovoltaic panel are both placed horizontally, the condensed water droplets will drip on the photovoltaic panel, which will affect the experiment to a certain extent. The collected water droplets flow back into the water tank 303 for continued use. The water tank 303 can also be opened for maintenance and cleaning at a later stage. A water pump device is also installed in the test box 1 to facilitate the transportation of water in the water tank into the detection cavity 103 through atomization, so as to create a wet heat environment in conjunction with the Gat element.

When the motor 501 is started, it will not only drive the first hinge shaft 502 to rotate, but also drive the pulley group 601 to rotate. The first hinge shaft 502 and the second hinge shaft 503 are hinged, which will drive the second hinge shaft 503 to rotate, thereby driving the limit block 504 to move forward and backward. The forward and backward movements of the limit block 504 are carried out in the limit groove in 512 and are limited by the rectangular limit groove.

[0039] In this embodiment, when the motor 501 drives the supporting platform 506 to flip and descend from facing the door opening to facing the main light panel 2, the pulley group 601 will also rotate at the same time, and the rotation will also be transmitted to the first incomplete gear 604 through the transmission of the bevel gear group. However, at this time, the convex arc portion in the first incomplete gear 604 and the concave arc portion in the second incomplete gear 605 are in close contact and rotate, and there is no meshing relationship, and the second incomplete gear 605 cannot be driven. Only when it continues to rotate, that is, when the supporting platform 506 continues to descend, will the convex portion 6041 rotate to one side of the toggle shaft 6051, and the convex portion 6041 causes the toggle shaft 6051 to rotate, and the toggle shaft 6051 drives the second incomplete gear 605 to rotate, so that the gear portion between the first incomplete gear 604 and the second incomplete gear 605 rotates, thereby driving the shaft below the second incomplete gear 605 and the upper linkage shaft 606 to rotate.

[0040] Specifically, a pulley group 601 is connected to one side of the output end of the motor 501, and the pulley group 601 includes two groups of pulleys and belts connected to the outside thereof, and one side of one group of pulleys is connected to a first bevel gear 602, a second bevel gear 603 is meshed above the first bevel gear 602, the second bevel gear 603 is connected to a first incomplete gear 604 through an axis, and the first incomplete gear 604 includes a gear portion and a raised arc portion, and a raised portion 6041 is also connected above the first incomplete gear 604.

[0041] In this embodiment, the first incomplete gear 604 and the second incomplete gear 605 are located in the same plane, the protrusion 6041 and the shifting shaft 6051 are located in the same plane, and when the protrusion 6041 rotates to the side of the shifting shaft 6051, the shifting shaft 6051 rotates due to the protrusion shifting, causing the second incomplete gear 605 to break away from the state of contact with the arc portion of the first incomplete gear 604, changing it to gear contact.

[0043] In this embodiment, the upper linkage shaft 606 is driven to rotate by the inner shaft below the second incomplete gear 605, and the inner shaft rotates inside the outer sleeve 608. The outer sleeve 608 is fixedly arranged, and a mounting plate is provided on one side thereof, which is fixedly installed in the test box 1. The upper linkage shaft 606 and the lower linkage shaft 6010 below both rotate with the outer sleeve 608 as a fixed point.

[0044] Specifically, an inner shaft is arranged below the second incomplete gear 605, and the inner shaft is arranged inside the outer sleeve 608, the outer side of one end of the inner shaft is connected to the upper linkage shaft 606, and the tail end of the connecting sleeve 609 and the tail end of the outer sleeve 608 are commonly connected to the lower linkage shaft 6010.

[0045] In this embodiment, a fixed shaft is provided at the bottom end of the upper linkage shaft 606, and the upper linkage shaft 606 is connected to the lower linkage shaft 6010 through the fixed shaft. When the upper linkage shaft 606 rotates, the lower linkage shaft 6010 connected through the fixed shaft rotates at the same time, and the second short hinge shaft 6013 and the long hinge shaft 6012 and the first short hinge shaft 6011 on the outside of the outer sleeve 608 are deformed to cooperate with the rotation.

[0046] Specifically, the outer side of the connecting sleeve 609 is connected to the first short hinge shaft 6011, and one end of the first short hinge shaft 6011 is hinged to the long hinge shaft 6012, one end of the long hinge shaft 6012 is hinged to the second short hinge shaft 6013, and the other end of the second short hinge shaft 6013 is arranged on the outer side of the outer sleeve 608, and one side of the fourth bevel gear 6014 is connected to the mounting block 6015, and the mounting block 6015 is arranged on the inner side of the movable door 4.

[0047] In this embodiment, a connecting column is provided on one side of the connecting sleeve 609, and the connecting column is connected to the fourth bevel gear 6014. When the third bevel gear 607 is displaced and rotated, the fourth bevel gear 6014 meshing therewith is driven to rotate, thereby driving the movable door 4 to rotate through the mounting block 6015, so that the movement trajectory of the movable door 4 is to be vertically stored after being pushed out, exposing the spare light panel 3 installed inside the protective shell 401 without taking up space, and the inner shell of the protective shell 401 is provided with a heat insulation structure, and when the main light panel 2 is subjected to the experiment, the influence on the spare light panel 3 is reduced, and a sealing structure is provided between the protective shell 401 and the movable door 4, and the influence of moisture on the spare light panel 3 is reduced when it is closed.

[0048] When in use, an external power source can be connected to provide power to the device so that the device can operate normally. First, after opening the door outside the test box 1, the photovoltaic panel can be placed on one side of the support platform 506 and clamped and fixed, and then its power cord can be connected to the detection equipment above through the channel. The door can be closed to start the experiment, and the motor 501 is started so that the first hinge shaft 502 drives the second hinge shaft 503 to rotate a certain amount below 512, so that the limit block 504 moves downward. At the same time, the limit bead 508 located in the flipping part of the limit slide 5010 also moves with the movement of the limit block 504, so that it moves along the flipping part to the translation part to complete the flipping action. In this way, the support platform 506 can be driven downward and flipped through the long axis 505, so that it is located on one side of the main light panel 2. The main light panel 2 is turned on, and the photovoltaic panel is exposed to simulated sunlight. At the same time, the heating element and the humidifying element installed in the test box 1 are subjected to the experiment of hot and humid environment, and the detection data are observed on the detection equipment; If the main light panel 2 is damaged during the experiment, the backup light panel 3 can be started, and the motor 501 continues to start to drive the limit block 504 to descend, and the limit bead 508 continues to move downward in the translation portion of the limit slide groove 5010, thereby continuing to drive the carrier 506 carrying the photovoltaic panel to descend, and at the same time the pulley group 601 will also be driven to rotate, and the rotation of the pulley group 601 drives the first bevel gear 602 to rotate, thereby driving the second bevel gear 603 meshing with it to rotate, and the second bevel gear 603 drives the first incomplete gear 604 to rotate. At this time, the gear portion in the first incomplete gear 604 is in contact with the gear portion in the second incomplete gear 605. Because of the meshing, the second incomplete gear 605 rotates, and the second incomplete gear 605 rotates. The rotation of the wheel 605 will drive the upper linkage shaft 606 to rotate through the shaft, thereby causing the third bevel gear 607 to be displaced. The upper linkage shaft 606 drives the lower linkage shaft 6010 to rotate together through the fixed shaft below. Through the hinged cooperation of the second short hinge shaft 6013, the long hinge shaft 6012 and the first short hinge shaft 6011, the movable door 4 is pushed from one side of the protective shell 401 to open it, and the fourth bevel gear 6014 meshing with the third bevel gear 607 will drive the movable door 4 to rotate through the mounting block 6015, so that it is vertically stored on one side of the movable door 4 to reduce the occupied space. The opened movable door 4 exposes the spare light panel 3, so that the descending photovoltaic panel is located on one side of the spare light panel 3 to receive light, and the wet heat detection continues.
