In order to respond to the national natural environment protection requirements, hazardous wastes (transformer oil) generated by scrapped distribution transformers (distribution transformers for short) need to be recycled. The existing recovery modes of scrapped distribution transformer oil comprise the following two modes: (1) the oil level is lowered to the position below the distribution transformer top plate by opening the oil outlet valve below the distribution transformer side face, the top plate is disassembled, and the oil pumping pipe is placed into the oil tank to pump oil. This kind of mode need unpack each roof of scrapping distribution transformer apart, just can carry out the oil pumping operation, increases along with distribution network engineering volume, and the quantity of scrapping distribution transformer along with increasing, dismantles not only extravagant manpower and materials of roof of scrapping distribution transformer, and the process is complicated moreover, and is consuming time long, and direct influence is scrapped and is joined in marriage the oily efficiency of collection that changes. (2) And opening an oil outlet valve below the side surface of the distribution transformer, adopting a container to carry, and putting an oil pipe into an oil collecting container to pump oil. Because the distance between the position of the oil outlet valve below the side face of the distribution transformer and the bottom of the distribution transformer is still 20-50mm, part of distribution transformer oil still remains at the bottom only by unscrewing the oil outlet valve for oil drainage, and the oil liquid remaining at the bottom still needs to be extracted through the oil pumping pipe, so that the oil collecting efficiency of the scrapped distribution transformer is greatly reduced. In addition, in addition to the above disadvantages, the present embodiment also finds that the existing oil collecting method has the following disadvantages: (3) the handling many times causes the oil pumping consumption to be long: the distribution transformer is loaded and unloaded in an oil pumping operation area through a forklift and a crane, the distribution transformer moves to a storage area after oil pumping is finished, space limitation is caused, loading and unloading operations of the forklift, the crane and the like cannot be synchronously carried out with an oil pumping vehicle, and the oil pumping operation and the loading and unloading operation are alternately carried out. The single distribution transformer takes about 10 minutes from a storage area to an operation area, the whole carrying, loading and unloading process takes about 3 minutes, the preparation work such as positioning and the like takes about 30 minutes, the oil discharge process takes about 2 minutes, and the large oil pumping waiting waste time exists; (4) the oil pumping pipe is transposed many times, and the seepage risk is big: after the main transformer oil pumping pipe is communicated with the oil outlet once, the valve is opened, and oil can be stably pumped. However, one distribution transformer only contains 150kg of oil with the weight of 100-; (5) it is difficult to control the oil pressure when unscrewing the delivery valve, and it is big to spray the pollution risk: the size of the oil receiving container is limited, and if the oil receiving container is placed at a position too close to the distance between the transformer and the oil receiving container, the oil pressure is large after the oil receiving container is unscrewed, and the oil receiving container can be sprayed out of the container; if the distance between the position where the oil receiving container is placed and the transformer is too far, the oil pressure is small after the oil receiving container is unscrewed, and the oil can directly drop outside the container; the oil pressure of the same transformer is reduced in the oil discharging process.

(2) the inclination angle of the oil collecting conduit 3 can be adjusted through the first adjusting mechanism 1, so that the oil collecting conduit 3 is obliquely arranged, the oil collecting tank 4 is positioned at the lower end of the oil collecting conduit 3, oil in the scrapped distribution transformer 6 flows into the oil collecting conduit 3 through the oil outlet valve, and the oil collecting conduit 3 which is obliquely arranged enables the oil to gradually flow into the oil collecting tank 4 under the action of gravity, so that the flowing speed of the oil in the oil collecting conduit 3 can be increased, and the oil collecting efficiency of the scrapped distribution transformer 6 can be improved;
(3) the inclination angle of the scrapped distribution transformer 6 can be adjusted through the second adjusting mechanism 2, so that the scrapped distribution transformer 6 is arranged obliquely, the oil outlet valve of the scrapped distribution transformer 6 is positioned at the lower end of the scrapped distribution transformer 6, and oil at the bottom of the scrapped distribution transformer 6 can be discharged through the oil outlet valve, so that residual oil at the bottom of the scrapped distribution transformer 6 is greatly reduced, and the oil collecting efficiency of the scrapped distribution transformer 6 is improved;
(4) the oil collecting guide pipe 3 and the scrapped companions in one row divide the space into two parts, one side is used for placing an oil pumping vehicle, the other side is used for arranging a station for oil distribution and transformation to be drained, the distribution and transformation can be arranged in a straight line shape during oil pumping operation, each station operates independently, the stations are not influenced, and waiting waste is reduced. The other side of the scrapped distribution transformer 6, which is far away from the oil collecting device, is used for carrying a loading and unloading area 8 by a forklift and is communicated with a scrapped distribution transformer storage area 9, so that synchronous and uninterrupted loading, unloading, carrying and recycling of oil pumping are realized, and the waste time of oil pumping waiting is greatly reduced;
(5) the oil in the scrapped distribution transformers 6 is recovered through the same oil collecting conduit 3 and the same oil collecting tank 4, the oil pumping pipe 71 does not need to be transposed for multiple times, the phenomena of dripping, leakage and the like of residual transformer oil on the oil pipe, which are easily caused in the transposition process, are avoided, and the leakage risk is effectively reduced;
(6) the oil sprayed from the oil outlet valve of the scrapped distribution transformer 6 is blocked by the inner side wall of the oil collecting conduit 3, so that the oil flows back into the inner cavity of the oil collecting conduit 3, and the oil pressure is difficult to control when the oil outlet valve is unscrewed, and the pollution accident caused by spraying is effectively avoided.
