Description

Technical Field

[0001] The utility model relates to an observation device for the inner wall of a furnace, in particular to an endoscope device used for observing cracks on the wall of a high-temperature narrow space. Background Art

[0002] In high-temperature environments, such as coke ovens and hot blast furnaces, various types of damage, such as cracks and corrosion, may occur inside the furnace. These damages can lead to poor sealing, performance degradation, and even safety or environmental hazards. However, due to the unique characteristics of these environments, conventional endoscopy devices often fail to meet these requirements. In high-temperature environments, the lens of an endoscopy device may be affected by the high temperature, resulting in degraded image quality. Furthermore, the confined space poses challenges to the size and shape of the endoscopy device. While existing technical solutions have addressed the impact of high temperatures and confined spaces on endoscopy devices to some extent, some problems and shortcomings remain. First, existing cooling devices often fail to effectively reduce the temperature of the lens, especially in extremely high-temperature environments. Second, while existing endoscopy device designs can accommodate confined spaces, their functionality and performance may be compromised in such situations. In particular, the confined space may not allow for adequate cooling equipment, resulting in an inability to effectively control the lens temperature. Furthermore, the confined space can also affect the operation of the endoscopy device, making it more difficult to use. Furthermore, these solutions often increase the complexity and cost of the endoscopy device.

[0003] Therefore, the known high-temperature narrow space wall crack observation device structure has the above-mentioned inconveniences and problems. Utility Model Content
