Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
The utility model provides a novel oil-immersed transformer, includes oil tank body 1 and oil tank cap 2, wherein 1 lateral wall top of oil tank body is provided with the outer 3 of following of round oil tank, and is provided with sealed 4 of filling up between 3 of outer edge of oil tank cap 2 and oil tank.
2 top borders of fuel tank cap evenly are provided with just to the outer arch 5 along 3 of fuel tank, and wherein protruding 5 highly is 0.5 ~ 1.5cm to be provided with the mounting hole I7 that passes fuel tank cap 2 on protruding 5, and the edges of edges and corners of mounting hole I7 bottom opening part are provided with round draw-in groove I9, be provided with the mounting hole II8 that corresponds mounting hole I7 on the fuel tank border 3, wherein the edges and corners edge of mounting hole II8 top opening part is provided with round draw-in groove II10, both ends are provided with respectively about the sealed 4 sleeve pipe 11 that extends to in corresponding draw-in groove I9 and the draw-in groove II10, and wherein protruding 5 top is provided with the bolt that passes corresponding mounting hole I7, sleeve pipe 11, sealed 4 of filling up and mounting hole II8 in proper order, and the spiro union has nut 14 on the bolt 13 of 3 bottoms of.
In this embodiment, the oil tank cap 2, the sealing gasket 4 and the outer edge 3 of the oil tank are locked and fixed together by the screw nuts 14 and the screw bolts 13, so as to achieve a sealing and locking effect, wherein the sleeve pipes 11 clamped into the clamping grooves I9 and the clamping grooves II10 can effectively prevent the sealing gasket 4 from moving between the outer edge 3 of the oil tank cap 2 and the outer edge 3 of the oil tank, so that the sealing gasket 4 can be displaced at will, and this plays an active role in improving the installation effect and the sealing performance of the sealing gasket 4. Meanwhile, the sleeve 11 and the sealing gasket 4 are integrally arranged, wherein the edge of the sleeve 11 is provided with a fillet 12 so that the sleeve 11 can be conveniently inserted into the corresponding clamping groove I9 and the corresponding clamping groove II 10.
Wherein, because of the height difference between the top end of the fuel tank cap 2 and the top end of the protrusion 5, the liquid on the top of the fuel tank cap 2 is not easy to infiltrate into the mounting hole I7 through the gap between the head of the bolt 13 and the top end of the protrusion 5 and infiltrate into the fuel tank through the gap between the fuel tank cap 2 and the fuel tank outer rim 3, and because the diameter of the head of the bolt 13 is larger than the diameter of the protrusion 5, the liquid can not be deposited on the top end of the protrusion 5 and infiltrate into the mounting hole I7 through the gap between the head of the protrusion 5 and the head of the bolt 13.
And still be provided with the U type guard plate 6 that will correspond protruding 5 and surround at fuel tank cap 2 top, the 6 openings of guard plate set up towards fuel tank cap 2 outside direction, wherein be in same perpendicular between the both ends of guard plate 6 and the lateral wall that fuel tank cap 2 corresponds, and the guard plate 6 top is higher than bolt 13 top horizontal plane, so when fuel tank cap 2 top liquid flow to its edge all around and when falling, guard plate 6 can block the liquid that flows to fuel tank cap 2 edge and prevent its and bolt 13 and protruding 5 contact, but flows down by the fuel tank cap 2 edge of guard plate 6 both sides, so when the liquid that the fuel tank cap 2 top flows down can not contact with bolt 13 and protruding 5 after, this also can prevent to take place because of the problem in fuel tank cap 2 top liquid contacts with protruding 5 and bolt 13 often infiltrates mounting hole I7 when flowing down.
Simultaneously, the top end surface of the oil tank cover 2 in the opening of the protection plate 6 is inclined downwards towards the opening of the protection plate 6, so that rainwater dropping in the protection plate 6 can flow down along the inclined surface on the oil tank cover 2 in the protection plate in rainy days, and the rainwater cannot be deposited on the top of the oil tank cover 2 in the opening of the protection plate 6 for a long time.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
