Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel glow test technology, and in particular to a glow wire tester. Background Technology

[0002] Against the backdrop of the rapid development of the photovoltaic industry, photovoltaic panels are exposed to the outdoors for a long time. The flame retardant properties of the polymer materials used in their frames, junction boxes and other components directly affect the safety of the equipment. Existing glow wire testers have been gradually applied to photovoltaic panel material testing. By heating the glow wire body to simulate overload resistance or high temperature environment, the tester can detect whether the material is ignited. These testers usually include a test box, a storage component and a fixing structure. Some devices are equipped with temperature control and observation components, which can initially meet the basic flame retardant testing needs of small-sized photovoltaic panel samples and provide certain technical support for the safety assessment of photovoltaic products.

[0003] Existing glow wire testers are difficult to adapt to irregularly shaped and long components such as photovoltaic panel frames and long terminals in photovoltaic panel testing. The fixed structure lacks flexibility and cannot stably clamp photovoltaic panel samples of different specifications. During testing, the sample position needs to be manually adjusted to achieve multi-point detection. The high temperature inside the chamber can easily cause safety risks. In addition, there is no convenient sample flipping function, which cannot efficiently complete the testing of the front and back of photovoltaic panel materials. At the same time, the drip collection component is inconvenient to operate, affecting the cleaning efficiency after testing. It is difficult to meet the requirements of large-scale and high-precision flame retardant testing of photovoltaic panels. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a glow wire tester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A glow wire tester includes a glow wire test chamber, inside which is a storage component. The storage component includes a storage plate, a drip outlet at the center of the storage plate, an installation groove inside the storage plate, a receiving plate that slides inside the installation groove, the receiving plate being positioned at the drip outlet, and two screw-rail assemblies mounted on the top surface of the storage plate by screws. The fixed assembly includes a connecting plate and bolts. The connecting plate is set on the screw slide rail assembly. A ball bearing is installed on the top surface of the connecting plate. A threaded hole plate is provided on the side wall of the connecting plate. An mounting plate is installed on the inner ring of the ball bearing. A mounting frame is movably installed inside the mounting plate. An insertion hole is opened on the mounting plate. The threaded hole plate and the threaded hole are threaded with bolts inside the insertion hole. A threaded hole is made on one side of the mounting frame, and a limiting cylinder is installed inside the threaded hole. A fixing plate is installed on one end of the limiting cylinder, and a through hole is made on the fixing plate. A threaded rod is fitted inside the through hole of the mounting frame, the limiting cylinder and the fixing plate. A connecting cylinder is installed at one end of the threaded rod, and the connecting cylinder is installed on the inner side wall of the mounting frame. A pressure plate is threaded onto the threaded rod.

[0006] Preferably, the glow wire test chamber has four support legs installed at the bottom corners, and the electrical control cabinet door is hinged to one side of the glow wire test chamber, with an insulated observation window on the electrical control cabinet door.

[0007] Preferably, the glow wire test chamber is equipped with a control panel, the glow wire body is installed inside the glow wire test chamber, the glow wire body's glowing end faces the fixed plate, and two limiting plates are installed on the bottom surface inside the glow wire test chamber, with the limiting plates slidingly engaging with the placement component.

[0008] Preferably, support plates are installed at the four corners of the bottom surface of the storage panel of the storage component, and the support plates are slidably fitted inside the limiting plate.

[0009] Preferably, a pull rod is installed on one side of the receiving plate, with one end of the pull rod located outside the storage component.

[0010] Preferably, a slide rail is provided on the top surface of the mounting plate, two mounting blocks are installed at both ends of the slide rail, a bidirectional threaded rod is movably installed between the two mounting blocks, a movable block is threaded onto the bidirectional threaded rod, and a mounting frame is installed on the top of the movable block.

[0011] Preferably, the lead screw and slide rail assembly includes a slide rail and a slider, the slide rail and the slider cooperate, and a connecting plate is installed on the top surface of the slider.

[0012] This utility model has the following beneficial effects: 1. The screw slide rail assembly on the top surface of the central plate of this utility model can drive the fixed component to move along the slide rail. In conjunction with the moving block driven by the bidirectional threaded rod on the mounting plate, the position of the mounting frame can be flexibly adjusted, easily adapting to photovoltaic panel frames, long terminals and other parts of different sizes and shapes. The combination of the threaded rod and the pressure plate in the mounting frame can clamp photovoltaic panel samples of different thicknesses by rotating the threaded rod. At the same time, the limiting cylinder can limit the deviation of the threaded rod and ensure stable clamping.

[0013] 2. The electrical control cabinet door of this utility model is equipped with a heat-insulated observation window, which allows for observation of the test status in a closed high-temperature environment, avoiding direct contact between operators and high-temperature areas. The receiving plate slides with the mounting groove through a pull rod, and can be pulled out to clean up drips without opening the cabinet door after testing, reducing the risk of high-temperature burns. The ball bearings in the fixing components are positioned with bolts, and the mounting plate can be rotated to flip the sample by simply loosening the bolts, without disassembling the sample. This efficiently completes the front and back testing of photovoltaic panel materials, eliminating the tediousness and safety hazards of traditional manual flipping.

[0014] 3. In this utility model, the support plate of the placement component slides in conjunction with the limiting plate inside the test chamber to ensure accurate positioning when the placement plate moves, avoiding sample displacement from affecting the test results. The hot wire body is set facing the fixed plate, and with the adjustable fixing component, it can ensure that the distance between the hot wire and the test point of the photovoltaic panel is consistent, improving the accuracy of the test data. The control panel can integrate functions such as temperature control and displacement adjustment. Combined with the smooth movement of the lead screw slide rail assembly, it can realize automatic testing of multiple points of photovoltaic panels without the need for repeated manual adjustments, shortening the test cycle and meeting the needs of large-scale flame retardant performance testing of photovoltaic panels.

When the sample needs to be flipped, loosen the bolt 10, rotate the mounting plate 304 through the ball bearing 302, and then tighten the bolt 10 to fix it. During the test, the dripping material falls into the receiving plate 205 through the drip outlet 203 and can be pulled out of the box for cleaning by the pull rod 206. After the test is completed, turn off the equipment and open the electrical control cabinet door 102 to take out the sample after cooling.
