Corrugated oil tank maintenance and cleaning equipment for large and medium-sized transformers in power grids

Abstract

The invention discloses a maintaining and cleaning device for a corrugated oil tank used for an electric power grid large and medium-sized transformer. The maintaining and cleaning device comprises a first lifting device (1), an up-down guide rail frame (2), a screw rod (3), a screw rod motor (4), an up-down sliding frame (5), a front-back guide rail frame (6), a rotation device (7), a sliding power device (8), a cleaning hook block (9) and a cleaning hook (10). The device achieves automatic cleaning through cooperation of all the parts, and the cleaning efficiency and stability are improved; multiple lifting cleaning assemblies can be configured according to needs to remove garbage in a gap of the corrugated oil tank at the same time, and operation is more flexible; a first cleaning piece and a second cleaning piece of the cleaning hook are made of flexible materials, the surface of a transformer cooling fin cannot be damaged, the distance between the first cleaning piece and the second cleaning piece can be automatically adjusted according to the distance of corrugations of the corrugated oil tank, and corrugated oil tanks with different distances can be cleaned; and control is simple, the cleaning operation can be completed through one worker, and labor force is saved.

Description

technical field [0001] The invention belongs to power grid maintenance equipment, in particular to a corrugated oil tank maintenance and cleaning equipment for large and medium-sized transformers in the power grid. Background technique [0002] The tank wall of the corrugated fuel tank is made of thin steel plate, which has high mechanical strength and elastic deformation capacity. When the temperature rises, the corrugation of the tank wall expands, and when the temperature decreases, the corrugation of the tank wall shrinks, so there is no need to The oil conservator is installed on the oil tank cover, and the expansion and contraction of the transformer oil volume caused by temperature changes can be compensated by the expansion and contraction of the corrugated walls of the oil tank. [0003] Corrugated oil tanks are mostly used in large and medium-sized power transformers, and their working environment is mostly outdoors. Various sundries and garbage are often entrained...

AI Technical Summary

Problems solved by technology

[0003] Corrugated oil tanks are mostly used in large and medium-sized power transformers, and their working environment is mostly outdoors. Various sundries and garbage are often entrained by the wind between the corrugated tanks, such as plastic bags, debris, small pieces of wood and other hard objects. Between the corrugations, it affects the heat dissipation of the transformer. Sometimes the transformer oil temperature will reach 85 degrees and above, which will easily cause the debris between the corrugations to burn, which will bring great hidden dangers to the safe power supply. At the same time, if there are hard objects such as wood blocks between the corrugations Garbage that is not easy to be compressed and deformed will affect the expansion and deformation of the oil tank wall. Under the action of thermal expansion, the oil tank wall may even be crushed, causing transformer oil to leak, and eventually the transformer cannot work normally, causing huge economic losses.

[0004] At present, the corrugated fuel tank cannot be flushed with water, which has a great safety risk, and the use of high-pressure gas cannot solve the hard objects such as blocks in the corrugated fuel tank, and there is no automatic maintenance and cleaning equipment for the corrugated fuel tank, which cannot achieve high efficiency. , safe cleaning corrugated fuel tank
