As shown in fig. 1 to 4, the present invention provides a power transformer spraying system, which includes a transformer 1 and cooling fin assemblies 2 installed around the transformer 1, wherein the cooling fin assemblies 2 include a plurality of cooling fins 3 symmetrically installed on the outer side wall of the transformer, a plurality of ion detectors 6 are installed at the bottom of the cooling fin assemblies 2, a spraying assembly 4 is installed at the top of the cooling fin assemblies 2, and the spraying assembly 4 is connected with a water supply assembly 5;
the spray assembly 4 includes a bracket 401 fixedly coupled to the top of the fin assembly 2 and a circulation assembly 404 installed on the sidewall of the transformer 1, and the circulating assembly 404 is positioned at the bottom of the radiating fin assembly 2, the bracket 401 is fixedly connected with a first annular pipeline 402 and a second annular pipeline 403 in turn up and down, and first ring conduit 402 is connected with water supply assembly 5, the bottom symmetry intercommunication of first ring conduit 402 has a plurality of atomizing pipe 405, the bottom of every atomizing pipe 405 all is connected with atomizer 406, the top symmetry intercommunication of second ring conduit 403 has four connecting pipes 407 with first ring conduit 402 bottom intercommunication, all install the solenoid valve 408 with a plurality of ion detector 6 electric connection on every connecting pipe 407, the bottom intercommunication of second ring conduit 403 has a plurality of shower 409 that are located between two adjacent fin 3, a plurality of jet orifice group 410 has all been seted up on the lateral wall of every shower 9.
When the transformer cooling structure is used, the cooling fin assembly 2 is used for normally cooling the transformer 1, the cooling fin assembly 2 comprises four groups of cooling fins 3, and each group of cooling fins 3 is arranged on one side of the transformer 1.
A spray assembly 4 is mounted on top of the fin assembly 1 and the cooling water and the impact water pressure required by the spray assembly 4 are provided by a water supply assembly 5.
When the transformer 1 is in operation at a high external environment temperature or a high load, the generated heat cannot be dissipated in time through the heat dissipation fin assembly 2, the water supply assembly 5 provides water pressure and a water source, water enters the atomizing pipe 405 through the first annular pipeline 402, and is atomized and sprayed out through the atomizing nozzle 406 due to the existence of the water pressure, atomized water drops are attached to the surface of the heat dissipation fin 3, and the heat on the heat dissipation fin 3 is carried away by the heat absorption evaporation of the water for auxiliary cooling.
The plurality of atomizing spray heads 406 enable the two surfaces of the plurality of radiators 3 to be gathered with water drops for auxiliary cooling, the utilization efficiency of atomized water is higher, and waste of water resources caused by that a large amount of water is not enough to absorb heat and flows into the ground due to direct water splashing on the surfaces of the radiating fins 3 is avoided.
After the spraying system 4 is used for auxiliary cooling for a long time, because minerals, dust in water and dust in air are accumulated on the surface of the radiator 3 to form thick dirt, the cooling effect of the radiating fin 3 is reduced, and at the moment, the dirt on the surface of the radiating fin 3 needs to be cleaned.
The ion detector 6 is used for detecting the concentration of relevant ions in the water flow which flows downwards and is gathered by the water drops sprayed by the atomizing nozzle 406 on the surface of the radiator 3, when the concentration of more than one ion detector 6 exceeds a preset standard, the four electromagnetic valves 408 are opened, and the water supply of the water supply assembly 5 enters the spraying pipe 409 through the second annular pipeline 403.
The shower pipe 409 is rapidly filled with water and is sprayed to the outside through the spray hole groups 410 under the pressure of water pressure, the water sprayed from the plurality of spray hole groups 410 cleans the surface of the heat radiating fin 3, and the dirt on the surface of the heat radiating fin 3 is forcibly washed by the pressurized water sprayed from the spray holes 410, so that the dirt falls off from the surface of the heat radiating fin 3, the surface of the heat radiating fin 3 becomes clean again, and the normal heat radiating effect is recovered.
When the surface of the cooling fin 3 is washed, the surface of the cooling fin 3 is cooled, and the washed water is collected and reused through the circulating assembly 404, so that the water resource is saved, and the waste of the water resource is reduced.
When more than one ion detector 6 detects that the ion concentration in the downstream water flow is less than the preset level, the solenoid valve 408 is closed, the shower pipe 409 does not spray any more water flow through the spray hole group 410, and the cleaning is finished.
If the shower pipe 409 is directly connected through the first annular pipeline 402, more solenoid valves 408 are needed, which is higher in cost, and the four connecting pipes 407 are symmetrically arranged, so that the water supply of the water supply assembly 5 can quickly fill the second annular pipeline 403 and then enter the shower pipe 409, and through the transfer of the second annular pipeline 403, the number of the solenoid valves 408 used is small, and the same purpose can be achieved.
The spraying assembly 4 comprises two functions of atomizing water spraying and spraying cleaning, and is switched when needed, so that the waste of water resources is reduced.
The water supply assembly 5 includes a water reservoir 501 and a water supply pipe 502 connected to the water reservoir 501 by a water pump, and one end of the water supply pipe 502 communicates with the first circular pipe 402.
The water supply assembly 5 supplies water to the first circular pipe 402 through a water reservoir 501 as a water source for supplying water, a water pump for supplying water pressure, and a water supply pipe 502.
The circulating assembly 404 includes an annular water storage tank 411 fixedly connected to the sidewall of the transformer 1 and an inclined cover plate 412 installed at the notch of the annular water storage tank 411, a plurality of filtering holes 413 are opened on the inclined cover plate 412, a filtering net 414 is installed in each filtering hole 413, and the bottom of the annular water storage tank 411 is connected to the water storage tank 501 through a water storage pipeline.
The circulation assembly 404 is located at the bottom of the fin assembly 2 to facilitate the recovery of all water that passes over the surface of the fins 3.
The water flows into the inclined cover plate 412 on the circulating assembly 404, flows along the inclined surface of the inclined cover plate 412, and the dirt cleaned from the heat sink 3 is carried to the edge of the inclined cover plate 412 by the flow of the water flow, and is separated from the inclined cover plate 412 by the impact force of the dirt behind and the component force of the gravity along the inclined surface of the inclined cover plate 412 and falls to the ground.
The sewage flowing into the inclined cover plate 412 is filtered by the filter screen 414 in the filter hole 413, dirt is left on the surface of the inclined cover plate 412, and the filtered sewage flows into the annular water storage tank 411 and flows into the water storage tank 501 through the water storage pipeline for recycling.
Each injection hole group 410 includes a plurality of injection holes annularly arrayed on the side wall of the shower pipe 409, and the arrangement density of the plurality of injection hole groups 410 is gradually increased from top to bottom.
Because the atomizer 406 is located on the upper portion of the heat sink 3, and the dirt accumulated on the surface of the heat sink 3 is basically condensed at the lower position of the surface of the heat sink 3 due to the impact of the atomized water droplets on the surface of the heat sink 3 and the self gravity, the spray hole group 410 is arranged on the spray pipe 409 in a sparse-top-dense-bottom manner, and the reasonable arrangement and the reasonable allocation of resources are presented for flushing the surface of the heat sink 3.
The shower pipes 409 are cylindrical, and each shower pipe 409 has no injection hole on a radial plane parallel to the heat dissipation plane of the heat dissipation fins 3, and each shower pipe 409 is located at the center position between two adjacent heat dissipation fins 3.
When the spray holes are formed in the radial plane of the spray pipe 409 parallel to the plane of the heat sink 3, the spray direction is towards the transformer 1 and away from the transformer 1, and the water column away from the transformer 1 does not contact with the heat sink assembly 2 at all, which results in waste of water resources, so that no spray hole is formed in this direction.
The shower 409 that is located central point and puts can realize the washing to whole fin 3 surface, when being located one side of fin 3, because the opposite side of fin 3 is far away from shower 409, washes the relatively poor effect or even does not wash, consequently sets up the maximize that can realize resource utilization in central point, avoids needing the multiunit to set up extravagant resource.
The length of the shower pipe 409 is smaller than the length of the heat radiating fins 3 in the vertical direction.
If the length of the shower pipe 409 is greater than the length of the fin 3, a part of the injection hole group 410 is located outside the fin 3, so that the injected water column is wasted.
The bottoms of the plurality of atomizing pipes 405 are located between two corresponding adjacent cooling fins 3, and the two corresponding atomizing pipes 405 are symmetrically arranged on two sides of the corresponding second toroidal tube 403.
The atomizing pipes 405 symmetrically arranged on two sides of the second toroidal tube 403 can enable the connected atomizing nozzles 406 to be symmetrically arranged on two sides of the second toroidal tube 403, so that the cooling of the surface of the cooling fin 3 is more uniform, and the cooling effect is better.
The horizontal height of the annular water storage tank 411 is higher than that of the water storage tank 501, and the horizontal length of the annular water storage tank 411 is larger than that of the radiating fins 3.
The whole annular water storage tank 411 can completely collect and utilize water flowing down from the surface of the cooling fin 3, and water resources are saved.
The annular water storage tank 411 is high in height, water stored inside automatically flows into the water storage tank 501 under the action of gravity, and the problem that a water pump needs to be added to increase the use cost is solved.
The number of the ion detectors 6 is four, and each ion detector 6 is mounted at the bottom of the side face of the corresponding heat sink 3.
The symmetrical mounting makes the detection result of the ion detector 6 more accurate.
The bottom of the atomizer head 406 is in the same plane as the top of the fin assembly 2.
The atomizing nozzle 406 can cover most of the surface of the radiating fin 3, and the cooling effect is maximized.
