[0002] Oil leakage is a common problem existing in hydraulic equipment. When the oil leaks from the high-pressure chamber of the oil cylinder to the low-pressure chamber or leaks outside the cylinder block, it will cause the working mechanism to move unstably and be positioned inaccurately, with low volumetric efficiency. In severe cases, the system pressure cannot rise, and even the entire system cannot work. In addition, it will also cause a series of problems such as environmental pollution of the working environment and waste of oil.

Fixed devices are symmetrically arranged on both side walls of the base. A chute is opened at the longitudinal center of the base. A sliding platform is slidably arranged on the chute. An oil leakage recovery device is fixedly installed on the top of the sliding platform. An oil leakage detector is rotatably connected to the top of the oil leakage recovery device. The oil leakage detector includes an oil leakage detection barrel. An observation window is arranged at the lower end of the front surface of the oil leakage detection barrel. A coloring agent is placed at the bottom of the oil leakage detection barrel. An oil leakage hole communicating with the oil leakage recovery device is opened at the bottom of the oil leakage detection barrel. A pull rod is fixedly installed above the observation window. By providing the sliding platform, the sliding installation of the oil leakage detector is realized, solving the problem in the prior art that the space under the water turbine generator is narrow, and it is not easy to take out, repair and replace the oil leakage detection device fixedly installed under the water turbine generator, which affects its repair and replacement.
