Description

Technical Field

[0001] The utility model relates to the technical field of transformer radiating fins, in particular to a transformer radiating fin flushing device. Background Art

[0002] The heat sink of the transformer is a fin evenly distributed on both sides of the transformer. The heat generated inside the transformer is exchanged with the outside air through the heat sink to cool the transformer. Since the transformer is placed outdoors for a long time, a lot of dust adheres to the surface of the heat sink. The attached dust seriously hinders the heat exchange between the heat sink and the outside air, so maintenance personnel need to clean the heat sink regularly.

[0003] The current method of cleaning the heat sink is generally to use a high-pressure water gun by maintenance personnel to flush the heat sink. During the flushing, the maintenance personnel need to hold the high-pressure water gun to flush the gaps between each heat sink individually. This flushing method causes the maintenance personnel to have high workload and low cleaning efficiency; the manual cleaning method will cause the sewage to fall directly on the ground, which is inconvenient to clean and will also cause a waste of water resources.

[0004] Therefore, we propose a transformer heat sink flushing device to solve the above problems. Utility Model Content

[0024] The upper and lower ends of the movable rod 2 are installed on the back of the body 1 through the slide groove 101, and the movable rod 2 is movably connected to the sliding rod 3. A water guide channel 302 is opened inside the sliding rod 3, and the water guide channel 302 is connected to each nozzle 301. The water inlet of the water guide channel 302 is connected to the other end of the hose 501. Water can be sprayed out from the nozzle 301 through the movable sliding rod 3 and the water guide channel 302, so that the heat sink can be quickly rinsed.

[0025] The gear 601 is arranged inside the body 1, and the gear 601 contacts the top of the left fixed rod 7 and the right fixed rod 8. The inner side of the top of the left fixed rod 7 is set to a toothed groove matching the gear 601, and the inner side of the top of the right fixed rod 8 is set to a toothed groove matching the gear 601, and the clamping part of the right fixed rod 8 is in the same horizontal plane as the left fixed rod 7. A first limiting groove 103 is opened at the top of the body 1 at the position of the left fixed rod 7, and a second limiting groove 102 is opened at the top of the body 1 at the position of the right fixed rod 8. The movement of the left fixed rod 7 and the right fixed rod 8 on the body 1 can be controlled by rotating the gear 601, so as to facilitate fixing the flushing device on the transformer.

[0026] A limiting rod 104 is provided on the inner wall of the body 1 in contact with the back of the sewage tank 9, and the right end of the limiting rod 104 is provided inside the limiting column 901, and the right end of the limiting rod 104 is in contact with the left end of the spring 902. The limiting rod 104 can move in the limiting column 901 and the spring 902 can rebound, so that the sewage tank 9 can be close to the bottom of the transformer, which is convenient for collecting sewage.

[0027] The plane of the machine body 1 located on the top of the sewage tank 9 is set as a slope extending toward the sewage tank 9, so that the water spilled inside the machine body 1 can be collected into the sewage tank 9, avoiding the waste of water resources and facilitating the collection of sewage.

[0029] Working principle: When using the transformer heat sink flushing device, first align the flushing device with the heat sink that needs to be cleaned and move it toward the transformer so that the sewage tank 9 is close to the bottom of the transformer. At the same time, the spring 902 inside the limit column 901 is compressed by the limit rod 104. Then turn on the motor 6 to rotate the gear 601. The rotation of the gear 601 drives the left fixed rod 7 and the right fixed rod 8 to move in the first limit groove 102 and the second limit groove 103, so that the left fixed rod 7 and the right fixed rod 8 shrink inward, reduce the distance between the left fixed rod 7 and the right fixed rod 8, and make the left fixed rod 7 and the right fixed rod 8 clamp both sides of the heat sink, so that the flushing device is fixed on the transformer. Then turn on the water pump 5 to pump the clean water into the transformer through the hose 501. The water in the water tank 4 is sprayed out from the nozzle 301 through the water guide channel 302 to flush the heat sink, and then the movable rod 2 is moved horizontally on the body 1 through the slide groove 101, and the slide rod 3 is moved up and down on the movable rod 2 to comprehensively flush the heat sink. The sewage generated by the flushing flows into the sewage tank 9. After the flushing is completed, the motor 6 is reversed and the water pump 5 is turned off to make the flushing device leave the transformer and stop flushing the heat sink at the same time. Finally, the drain hole 903 at the bottom of the sewage tank 9 is opened to discharge the sewage in the sewage tank 9 from the drain hole 903. This completes the use of the transformer heat sink flushing device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
