Description

Technical Field

[0001] The invention relates to the technical field of automatic collection of oil samples, in particular to an automatic collection device for transformer oil samples. Background Art

[0002] The function of the transformer oil sample automatic collection device is to sample and analyze the transformer oil to detect the internal operation of the transformer. Through the analysis of the oil sample, the insulation state, moisture content, gas content, pollution degree, etc. of the transformer can be understood, and the fault condition of the transformer can be predicted, providing a favorable basis for the maintenance of the transformer; When the automatic transformer oil sample collecting device is in use, the device is usually fitted with the oil extraction point of the transformer to extract the oil, resulting in poor sealing during the extraction process, which makes the oil prone to leakage. At the same time, when the automatic transformer oil sample collecting device is in use, the waste oil is usually discharged through a pipeline, which makes it impossible to completely clean up the waste oil. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an automatic transformer oil sample collection device. When the oil inlet pipe is connected to the oil extraction point of the transformer, the sleeve ring can fit around the oil extraction point. By continuously squeezing the sleeve ring, the adsorption plate can be adsorbed around the oil extraction point. The elasticity of the spring is used to make the sleeve ring squeeze the spring and fit the surface of the liquid inlet pipe. The oil extraction point of the transformer can extend into the interior of the sleeve ring and fit the oil inlet pipe. When the oil extraction point of the transformer extends into the interior of the sleeve ring, the rubber strip can change its angle according to the entry direction of the pipeline and fit the surface of the external pipeline. When the oil inlet pipe is extracting oil, since the diameter of the inclined pipe is larger than that of the oil inlet pipe, it can be used as a joint to the outside world. The pipeline corresponds to the oil inlet pipe, and the drainage plate can be used to guide the oil dripping from the oil extraction into the inside of the oil inlet pipe, so that the oil is not easy to leak when the device is extracting oil. When the waste oil enters the waste oil box, the second motor is started to drive the screw rod to rotate. The rotation of the screw rod can drive the sliding sleeve to slide left and right on the surface of the sliding rod. When the sliding sleeve slides left and right, the sliding sleeve can drive the fixed plate and the scraper to move together. Since the scraper fits the inner bottom wall of the waste oil box, the scraper can discharge the waste oil in the waste oil box to the discharge pipe, making it more convenient and quick to clean the waste oil. The groove is used to allow the waste oil dripping from the discharge pipe to enter the groove for drainage and discharge, preventing the waste oil from dripping on the surface of the box to cause pollution.
