Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an oil leakage prevention protection device for hydraulic power machinery. Background Art

[0002] Hydraulic is the noun of mechanical power. Hydraulic can be called hydraulic transmission in the form of power transmission. Hydraulic transmission uses liquid as the working medium and uses the pressure energy of the liquid to transmit power. Mechanical equipment needs to be driven by hydraulic power to ensure the operation of the mechanical equipment. However, when the machinery providing hydraulic power is actually used, oil leakage often occurs at the connection between the oil pipe and the hydraulic oil tank. Therefore, an oil leakage protection device is usually set on the outside of the oil pipe to collect the leaked hydraulic oil, so that the staff can accurately count the amount of oil leakage, and take measures to avoid damage to the mechanical equipment due to excessive oil leakage. However, most of the existing oil leakage protection devices are not easy to disassemble during use. The protective shell of the protection device is usually directly fixed on the outside of the oil pipe, which makes it inconvenient to clean the residual oil in the protective shell, and it is also inconvenient to inspect and maintain the oil leakage at the oil pipe. Therefore, an anti-leakage protection device for hydraulic power machinery is proposed. Utility Model Content
