The invention relates to the technical field of excavators, and discloses an excavator hydraulic oil leakage protection device. The device comprises a shell, wherein an oil pipe is fixedly connected to the interior of the shell; an oil outlet hole is formed in the outer wall of the oil outlet pipe; an air bag is fixedly connected to the top of the oil pipe; a dielectric plate is fixedly connected to the top of the air bag; a positive plate is fixedly connected to the left side, close to the dielectric plate, in the shell; a negative plate is fixedly connected to the right side, close to the dielectric plate, in the shell; a piezoresistor is fixedly connected to the inner wall of the shell; and an indicator lamp is fixedly connected to the inner wall of the shell. According to the excavator hydraulic oil leakage protection device, the air bag drives the dielectric plate to move downwards, an electroactive polymer is electrified and contracted, the electroactive polymer drives a movable rod to move inwards, the movable rod drives a baffle to move inwards, and the baffle and the oil pipe are used in cooperation, so that the oil pipe can be effectively blocked, and the condition of continuous oil leakage is prevented.
Description
technical field [0001] The invention relates to the technical field of excavators, in particular to an excavator hydraulic oil leakage protection device. Background technique [0002] An excavator, also known as an excavator, is an earth-moving machine that uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into a transport vehicle or unloads them into a stockyard. The main power source of the excavator is to move through hydraulic pressure. And excavation, the main hydraulic material is oil, but there are often cases of oil leakage in excavators. [0003] Among the major excavator manufacturers, it is inevitable that some unqualified excavators will flow into the market. There will often be excavator oil leakage, resulting in insufficient power system, and cannot carry out normal excavation work. Some newcomers cannot detect it, resulting in oil leakage in the later stage. The situation is getting more and more serious, which serio...
