Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and more specifically, it relates to an oil-immersed transformer heat sink assembly with automatic dust removal function. Background Technology

[0002] The main purpose of cleaning the heat sinks of oil-immersed transformers is to prevent contamination accumulation, reduce the risk of failure, improve equipment performance, and extend equipment life. Dust and dirt can hinder heat dissipation from the heat sinks, causing the transformer temperature to rise and affecting operating efficiency and lifespan. Accumulated dirt may cause faults such as insulation breakdown and short circuits, and regular cleaning can reduce the probability of failure. Cleaned heat sinks have higher heat dissipation efficiency, which can reduce the transformer operating temperature and reduce energy loss. Removing contaminants can reduce corrosion and mechanical wear, and extend the overall service life of the transformer. However, most existing cleaning operations for the heat sinks of oil-immersed transformers are done manually, which not only results in incomplete cleaning of dead corners, but also wastes manpower and time. Utility Model Content

[0004] This utility model discloses an oil-immersed transformer heat sink assembly with automatic dust removal function, achieved through the following specific technical means: An oil-immersed transformer heat sink assembly with automatic dust removal function includes: a heat sink body; heat sink bodies are provided around the outer perimeter of the transformer, an upper top plate is provided on the upper side of the heat sink body, a lower bottom plate is provided on the lower side of the heat sink body, cleaning blocks are provided in the gaps between the heat sink bodies, a cleaning block is also provided on the outermost side of the heat sink body, cleaning brushes are provided on the side of the cleaning blocks that contacts the heat sink body, two sets of connecting plates are provided on the outer side of the cleaning blocks, the connecting plates connect all the cleaning blocks on the same side, and an electric telescopic rod is provided at the corner of the transformer, with the upper end of the electric telescopic rod connected to the cleaning block.

[0005] Furthermore, the electric telescopic rod is located at the corner of the lower base plate, and a fixing rod is provided at the upper end of the electric telescopic rod, which is connected to the outer side of the outermost cleaning block.

[0006] Furthermore, the inner side of the electric telescopic rod is provided with a sliding rod, and a sliding bearing is provided on the sliding rod. The sliding bearing is connected to the top of the electric telescopic rod through a round rod.

[0007] Furthermore, the cleaning block has grooves at both the top and bottom ends on its outer side, and the grooves are matched with the dimensions of the connecting rods at the top and bottom ends of the heat sink body.

[0008] Furthermore, the cleaning block has an opening on its upper side, which divides the upper part of the cleaning block 4 into two parts, and a support spring is provided between the two parts of the cleaning block.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a cleaning block and a cleaning brush, and an electric telescopic rod to perform cyclic reciprocating motion to clean dust particles attached to the heat sink, which can prevent the heat sink's heat dissipation capacity from decreasing due to dust particles.

[0010] 2. This utility model provides an opening and a cleaning spring on the upper side of the cleaning block. When the electric telescopic rod is extended to the top and the cleaning block moves to the top, the opening on both sides of the cleaning block extends to both sides under the action of the support spring, thus cleaning the dust particles attached to the upper side of the heat sink.
