Description

Technical Field

[0001] This utility model relates to the technical field of thermal shock testing equipment, and in particular to a thermal shock testing machine for glass insulators. Background Technology

[0002] As a crucial insulating component in power systems, the performance of glass insulators directly affects the safety and stability of power transmission. Thermal shock testing is one of the key tests for evaluating the quality and reliability of glass insulators.

[0003] In actual use, glass insulators may face environments such as large temperature differences between day and night and severe weather such as sudden rain or snow followed by exposure to sunlight. Thermal shock testing is precisely to artificially simulate these extreme working conditions and discover potential defects in products in advance.

[0004] The thermal shock test for glass insulators is a test method that simulates extreme temperature changes to detect whether glass insulators will crack, break, or experience performance degradation under rapid temperature alternation. It primarily assesses the mechanical strength and thermal stability of glass insulators, with particular attention to whether the joint between the glass component and the metal fittings can withstand the stress impact caused by drastic temperature changes.

[0005] A thermal shock testing device and method for glass insulators disclosed in Chinese patent CN118913981A improves the stability of the suspension frame by limiting the suspension bar through a limiting structure; improves the stability of the insulator body during transportation by fixing and limiting the insulator body through a fixing structure; and improves the heating effect of the drying box on the insulator body by sealing the drying box through a sealing structure.

[0006] However, compared with existing technologies and comparative solutions, it can be seen that this thermal shock testing equipment still has the following problems in actual use: Because glass insulators are relatively large, existing thermal shock testing equipment has varying distances between the heat source and different parts of the glass insulator during the heating process. This results in temperature differences between different parts of the glass insulator due to varying heating effects, leading to deviations in the thermal shock test results. Consequently, the test results cannot accurately reflect the performance of the glass insulator under extreme temperature changes, and may result in misjudgments of product quality. Utility Model Content

[0008] The purpose of this utility model is achieved through the following technical solution: a thermal shock testing machine for glass insulators, comprising a machine body and a placement mechanism provided on the machine body; The placement mechanism includes a connecting frame, on which a driving component is fixedly mounted, and at the bottom of the connecting frame a support net is fixedly connected. A connecting frame is fixedly connected to the bottom of the connecting frame, and a first connecting shaft is rotatably connected to the bottom of the connecting frame. A first helical gear is fixedly connected to one end of the first connecting shaft, and a second helical gear is fixedly connected to the end of the first connecting shaft away from the first helical gear. The output end of the drive unit is fixedly connected to a second connecting shaft, and a third helical gear is fixedly connected to the second connecting shaft; The support is rotatably connected to a fourth helical gear and a placement tray. A transmission gear is fixedly connected to the bottom of the fourth helical gear, and a toothed ring is fixedly connected to the bottom of the placement tray. An opening is provided in the middle of the placement tray.

[0009] Preferably, the machine body is provided with a cold water tank and a heating tank. The heating tank is provided with multiple electric heating rods, which are evenly distributed on the inner side of the heating tank. A water inlet pipe is fixedly connected to the top of one side of the cold water tank, and a drain pipe is fixedly connected to the bottom of one side of the cold water tank.

[0010] Preferably, there are two first connecting shafts, symmetrically distributed at the bottom of the connecting frame.

[0011] Preferably, the second connecting shaft is rotatably connected to the connecting frame.

[0012] Preferably, the end of the second connecting shaft near the third helical gear is rotatably connected to the support net, and the third helical gear meshes with the first helical gear.

[0013] Preferably, the fourth helical gear meshes with the second helical gear, and the gear ring meshes with the transmission gear.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This thermal shock testing machine for glass insulators ensures that different parts of the glass insulator are heated evenly during use, avoiding temperature differences caused by uneven heating of different parts of the glass insulator. This ensures the accuracy of the thermal shock test results and avoids misjudging the quality of the product.

There are two first connecting shafts 212, which are symmetrically distributed at the bottom of the connecting frame 21. A first helical gear 213 is fixedly connected to one end of the first connecting shaft 212, and a second helical gear 214 is fixedly connected to the end of the first connecting shaft 212 away from the first helical gear 213. like Figure 3 , Figure 5 and Figure 6 As shown, the output end of the drive unit 22 is fixedly connected to a second connecting shaft 221, the second connecting shaft 221 is rotatably connected to the connecting frame 21, a third helical gear 222 is fixedly connected to the second connecting shaft 221, and one end of the second connecting shaft 221 near the third helical gear 222 is rotatably connected to the support net 23. The third helical gear 222 meshes with the first helical gear 213. like Figures 3 to 8 As shown, a fourth helical gear 231 and a placement tray 232 are rotatably connected to the support net 23.
