Description

Technical Field

[0001] The utility model relates to the technical field of fuel tank cleanliness detection, and particularly relates to an oil cleanliness detection device. Background Art

[0002] Different oils are generally stored inside corresponding fuel tanks. The main function of a fuel tank is to store oil. For fuel tanks on some machines, especially those on some precision machines, there are sometimes high requirements for the cleanliness of the oil. If the cleanliness of the oil is not high, it may affect the normal use of the machine and even cause damage to the machine. However, traditional detection ignores the detection of the fuel tank. The low cleanliness of the fuel tank results in the cleanliness of the oil not meeting the expected effect. Currently, the detection of fuel tank cleanliness generally uses 3D vision equipment for photographic detection.

[0003] After retrieval, a patent for invention with the publication number CN110779929A specifically discloses a fuel tank cleanliness detection device based on 3D vision. The fuel tank cleanliness detection device based on 3D vision includes: a mounting plate; a main rod, the main rod is fixedly installed at the bottom of the mounting plate; a threaded sleeve, threads are provided on both the inner wall and the outer wall of the threaded sleeve, and the threaded sleeve is threadedly installed on the mounting plate; a first lead screw, the first lead screw passes through the threaded sleeve and is threadedly connected to the threaded sleeve; a connecting rod, the connecting rod is rotatably installed at the lower part of the lead screw; an elbow, the elbow is provided at the bottom end of the connecting rod. The fuel tank cleanliness detection device based on 3D vision provided by the present invention can enter the fuel tank through the fuel tank opening and can perform photographic detection on all six faces of the fuel tank, making it more convenient and simple to detect the cleanliness of the fuel tank.

[0004] In the above patent, the fuel tank cleanliness detection device based on 3D vision can enter the fuel tank through the fuel tank opening and can perform photographic detection on all six faces of the fuel tank. However, during the use of this device, due to the relatively large volume of the 3D vision module at the bottom end of the device, it is inconvenient for the device to enter and exit the fuel tank opening, so that the 3D vision module at the bottom end of the device is likely to be contaminated with oil at the fuel tank inlet and outlet, thereby affecting the detection visual effect of the device.

[0005] Therefore, it is very necessary for us to propose an oil cleanliness detection device to solve the above problems. Content of the Utility Model
