Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
The utility model provides an oil-immersed transformer that prevention of seepage was passed through, includes oil tank body 1 and oil tank cap 2, 2 top border departments of oil tank cap are provided with inclined plane 3, and wherein 1 lateral wall top of oil tank body is turned over and is rolled over the oil tank that has the round to extend to department under inclined plane 3 and follow 4 outward, and evenly be provided with protruding 5 on the inclined plane 3, be provided with the screw I6 that runs through oil tank cap 2 on protruding 5, wherein the oil tank is provided with the screw II7 that corresponds screw I6 on 4 outward, and protruding 5 tops be provided with and correspond screw I6 and screw II7 spiro union's bolt 8.
In this embodiment, the top end of the protrusion 5 is higher than the horizontal plane of the top end of the fuel tank cap 2, the protrusion 5 is in a circular truncated cone-shaped structure, and the head of the bolt 8 is not smaller than the minimum end diameter of the protrusion 5.
After the oil tank body 1 and the oil tank cover 2 are locked and fixed by the bolt 8 screwed with the screw hole I6 and the screw hole II7, the liquid at the top of the oil tank cover 2 is not easy to contact the top end of the protrusion 5 and flows into the space between the oil tank cover 2 and the outer edge 4 of the oil tank or permeates into the oil tank through the screw hole I6 and the screw hole II7 because of the higher height difference between the top end surface of the oil tank cover 2 and the top end of the protrusion 5, thereby having a positive effect on improving the safety of the oil tank.
In the above process, the protrusion 5 is disposed on the inclined plane 3, so that when the top of the fuel tank cap 2 drips liquid and then flows to the edge of the top of the fuel tank cap 2, the liquid is easy to flow down along the inclined plane 3 and is not easy to deposit at the edge of the top of the fuel tank cap 2, so that the liquid flowing to the edge of the top of the fuel tank cap 2 cannot deposit in a large amount and can reach the top end of the protrusion 5 to penetrate into the screw holes I6 and II7 from the top end surface of the protrusion, and simultaneously, the top end of the protrusion 5 is shielded by the head of the bolt 8, so that rainwater cannot drip at the top end of the protrusion 5 to penetrate into the screw holes I6 and II7 from the top end of the protrusion.
The edge of the oil tank cover 2 is downwards bent to form a vertical part I9, the bottom end of the vertical part I9 is outwards bent to form a horizontal part 10, the tail end of the horizontal part 10 is upwards bent to form a vertical part II11, a liquid storage tank 12 is formed among the vertical part I9, the horizontal part 10 and the vertical part II11, a spring 13 connected with the vertical part I9 and the vertical part II11 is uniformly arranged at the opening of the top of the liquid storage tank 12, a V-shaped spiral pipe 14 communicated with the liquid storage tank 12 is uniformly arranged at the bottom of the horizontal part 10, the spring 13 and the V-shaped spiral pipe 14 are arranged in a staggered mode, one end of the V-shaped spiral pipe 14 is screwed with a drainage pipe 15 which is obliquely arranged, and the water outlet end of the drainage pipe 15 extends to the outer side of a transformer cooling fin.
When the liquid on the top of the tank cap 2 flows down along the inclined surface 3, the liquid flows into the liquid storage tank 12 and is collected and discharged to the outside of the transformer through the V-shaped spiral tube 14 and the water discharge tube 15, so that the liquid dropped and collected on the top of the tank cap 2 is prevented from flowing to the components on the outside of the transformer, and the safety of the components on the outside of the transformer is improved.
In the process, the drain pipe 15 with the corresponding length can be installed according to the requirement to enable the drain pipe to be screwed with the V-shaped spiral pipe 14, so that the installation and the disassembly between the drain pipe and the V-shaped spiral pipe 14 are facilitated, wherein the V-shaped spiral pipe 14 can discharge the liquid collected in the liquid storage tank 13 through the drain pipe 15 so as to prevent the liquid from dropping on components outside the transformer.
Preferably, the included angle of the V-shaped spiral pipe 14 is greater than 90 degrees, and one end of the V-shaped spiral pipe 14 is vertically connected with the horizontal part 10.
Preferably, the top end of the vertical part II11 is lower than the level of the top end of the fuel tank cap 2, and the sidewall of the vertical part II11 is further provided with an overflow port 16 lower than the top end of the fuel tank cap 2.
When the V-shaped spiral pipe 14 cannot timely store the liquid in the liquid storage tank 12, the liquid can be discharged through the overflow port 16 to prevent the liquid in the liquid storage tank 12 from flowing backwards to the top of the oil tank cover 2 due to too high liquid level.
In this embodiment through vertical portion II11 and vertical portion I9 in order to protect oil tank cap 2 border, prevent that object and 2 border departments of oil tank cap from colliding with and losing its deformation, wherein still promote the steadiness between vertical portion I9 and the vertical portion II11 through spring 13, can extrude spring 13 and make its shrink and expand when vertical portion II11 receives the extrusion, and then play buffering shock attenuation effect to it through spring 13 and be used for preventing, indirectly play the guard action to 2 borders of oil tank cap.
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.
