Description

Technical Field

[0001] The invention relates to the technical field of visual detection, and more specifically to an oil leakage detection device for a transmission box of a hydraulic excavator engine. Background Art

[0002] The engine transmission box of a hydraulic excavator usually refers to the component that transmits the power of the engine to the hydraulic system and working device. This transmission box plays a key role in the hydraulic excavator. It can not only transmit the power of the engine, but also realize the distribution and regulation of power to ensure that the excavator can operate normally in various working modes. When detecting oil leakage in the engine transmission box of a hydraulic excavator, we often carefully observe whether there are obvious oil stains on the outside of the transmission box. These oil stains often appear along the edge or connection of the transmission box. The traditional visual inspection method is relatively simple and has many disadvantages. Its inspection efficiency is low and it is difficult to complete all inspection work in a short time. Secondly, it is difficult for visual inspection to fully cover the inspection inside the engine transmission box and in small spaces, so there is a potential problem of missed inspections.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention
