DETAILED DESCRIPTION

[0022] The principles and characteristics of the utility model are described below in conjunction with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0023] Example: Figure 1 As shown, the large transformer cooling auxiliary device of this embodiment includes two columns 1, a water pipe 2, a water inlet hose 3, multiple nozzles 4 and a lifting mechanism 5. The two columns 1 are respectively arranged vertically and spaced apart at the two end boundaries of the area where the fins of the cooler of the transformer are located. The water pipe 2 is horizontally arranged between the two columns 1, and the two ends are respectively connected to the two columns 1 for vertical sliding connection. The multiple nozzles 4 are respectively installed at intervals on the side of the water pipe 2 close to the fins. One end of the water pipe 2 is provided with a water inlet and is connected to a water source through the water inlet hose 3. The lifting mechanism 5 is installed on the column 1 and connected to the water pipe 2.

[0024] Before use, the large transformer cooling auxiliary device of this embodiment is fixed on the ground near the fin side of the transformer cooler (indicated by A in the figure), and the two columns 1 are respectively located at the two ends of the fin area. The water pipe 2 is placed horizontally between the two columns 1, and the two ends are respectively connected to the two columns 1 for sliding up and down. The water inlet hose 3 is connected to the water inlet of the water pipe 2 and the water source. When in use, the water pipe 2 is driven to move back and forth up and down along the two columns 1 by the lifting mechanism 5. During the movement, the water source enters the water pipe 2 and is sprayed from multiple nozzles 4. The gaps between the multiple nozzles 4 are reasonably set to ensure that the water mist sprayed by the multiple nozzles 4 can cover the fin area in the horizontal direction. As the water pipe 2 rises and falls, the fins can be sprayed with water mist in all directions. During the water mist spraying process, the cooler of the transformer is cooled synchronously, and under the action of the exhaust (exhaust fan) of the cooler, the water mist will be sent out and the cooling water mist will be sucked into the heat sink of the cooler to cool the heat sink, thereby enhancing the cooling effect of the main cooler. The entire device has a simple and reasonable structural design, and is easy and quick to construct. It can effectively combine with the air cooling of the transformer cooler to help improve the heat dissipation effect. The installation will not affect the original structure of the transformer, and it is very convenient to use and can be quickly assembled and disassembled.

[0025] In this embodiment, a bottom plate 11 is provided at the lower end of the column 1, and the bottom plate 11 is riveted to the ground by screws, ensuring that the column 1 can be firmly fixed to the ground.

[0026] In this embodiment, the pillar 1 is a hollow cylinder, which can reduce its own weight and consumables costs.

[0027] As a preferred embodiment, a slide rail 12 is provided on each side of the columns 1 that are close to each other, and a slider 13 is slidably mounted on the slide rail 12 , and the slider 13 is connected to both ends of the water pipe 2 .

[0028] In the above embodiment, the slide rail 12 is a vertical slide rail, and the sliding of the slide block 13 on the slide rail 12 ensures that the water pipe 2 can be lifted and lowered along the vertical direction by the lifting mechanism 5.

[0029] In the embodiment, the slide rail 12 can be an optical axis rod, and the slide block 13 can be a block-shaped member that is semi-enclosed on the optical axis rod.

The steel wire ropes 51 are provided in two and are respectively and correspondingly wound around the two pulleys 53. The upper ends of the two steel wire ropes 51 are respectively and correspondingly connected with the upper ends of the two slide blocks 13. The other ends of the two steel wire ropes 51 are respectively connected with the two winches 52.

[0031] In the above embodiment, when lifting is needed, the two winches 52 are synchronously wound or unwound. When winding, the two slide blocks 13 are pulled upward relative to the slide rail 12 by the two steel wire ropes 51, so as to drive the water pipe 2 to move up and down to realize the movable spraying. When unwinding, the water pipe 2 moves downward relative to the slide rail 12 to a lower position under the action of its own gravity. Such lifting structure runs more smoothly, and can ensure that the water pipe 2 has a larger movable displacement in the up-down direction, so as to ensure that the water pipe 2 can move to cover the fins in the vertical direction.

[0032] In the embodiment, the winch 52 can be an existing product of a suitable type on the market, which will not be described here.
