DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The specific embodiments are given below.

[0027] Please refer to Figure 1 - Figure 3 and Figure 5 The utility model provides a kind of outdoor oil-immersed box transformer oil storage device, the inner side wall surface of oil-water separation tank 12 is provided with two groups of horizontal lines 121, the top surface of oil storage tank 11 is fixedly connected with mixing plate 125, the two side surfaces of mixing plate 125 are fixedly connected on the outer side surface of oil-water separation tank 12, water inlet 124 is set in the junction of mixing plate 125 and oil-water separation tank 12, the top surface of mixing plate 125 is fixedly connected with hydraulic rod 122, the output end of hydraulic rod 122 is fixedly connected with lap support plate 123 that is movably lapped in the inner side wall surface of oil-water separation tank 12, and the outer side surface of lap support plate 123 is movably lapped in the entrance of water inlet 124, the bottom surface of oil-water separation tank 12 is fixedly connected with drain pipe 1210, the bottom inner side wall surface of oil-water separation tank 12 is fixedly connected with sleeve 126, water inlet 127 is set in the two side surfaces of sleeve 126, electric motor 128 is fixedly connected on the top inner side wall surface of sleeve 126, closing plate 129 that is movably sleeved in the inner side wall surface of sleeve 126 is fixedly connected on the output end of electric motor 128, and the outer side surface of closing plate 129 is movably lapped in the entrance of water inlet 127;

[0028] When working, the oil-water mixture with water source is guided into the inside of the oil-water separation tank 12, and the oil-water mixture is allowed to stand in the inside of the oil-water separation tank 12, and the oil is naturally floated to the water surface to realize separation by using the density difference between the oil and the water. After the oil-water separation, if the water source is higher than the top horizontal line 121, the closing plate 129 is rotated by the electric motor 128 at this time to remove the blockage at the entrance of the water outlet 127. The water outlet 127 without blockage allows the water source at the bottom of the oil-water separation tank 12 to quickly pass through the water outlet 127 and enter the inside of the drain pipe 1210, so as to discharge the excess water source and reduce the water source in the inside of the oil-water separation tank 12 to avoid the effect of too much water source.

[0029] With the continuous discharge of the water source, when the bottom horizontal line 121 is reached, the water outlet 127 is closed to stop the continuous discharge of the water source. The hydraulic rod 122 is used to lift the lap support plate 123 to open the entrance of the water inlet 124, and the oil separated from the inside of the oil-water separation tank 12 is guided into the inside of the mixing plate 125 through the water inlet 124, and the oil is concentrated by the oil tank 11. When the height of the oil is lower than the water inlet 124, the inside of the oil-water separation tank 12 is filled with oil-water again, and the oil-water is naturally separated again.

[0030] Further, as shown in Figure 1 and Figures 3 to 4 , comprising an oil tank 11 and oil-water separation tanks 12 fixedly installed on the two side surfaces of the oil tank 11, and a cooling hollow plate 13 detachably installed on the inner side wall of the oil tank 11, characterized in that a transmission rod 133 is movably sleeved on the inner side wall of the cooling hollow plate 13.

[0031] When working, the inside of the cooling hollow plate 13 is filled with gas by the high-pressure fan 131, and the compressed gas is compressed by the horn 132 and flows into the inside of the cooling hollow plate 13. The internal pressure of the compressed gas increases, and the flow of the gas is accelerated under the subsequent pushing of the gas. The rapidly flowing gas carries away the residual heat on the surface of the cooling hollow plate 13, so that the oil in the inside of the oil tank 11 can always remain in a low-temperature state, avoiding the effect that the high heat source on the surface of the oil tank 11 caused by the sunlight irradiation causes the oil to produce harmful gas and increases the internal pressure of the oil tank 11.

[0032] Further, as shown in Figure 1 and Figures 3 to 4As shown, the two ends of the transmission rod 133 are fixedly installed with push bars 134 on the inner side wall surface of the cooling hollow plate 13, the two side surfaces of the cooling hollow plate 13 are provided with trumpet mouths 132 on the outer side surface of the oil storage tank 11, the outer side surface of the trumpet mouth 132 is fixedly installed with a high-pressure fan 131, the outer side surface of the transmission rod 133 is movably sleeved with a counterweight ring 135 inside the oil storage tank 11, the bottom surface of the counterweight ring 135 is fixedly connected with a vertical plate 136, and the bottom two side surfaces of the vertical plate 136 are fixedly connected with swing bars 137.

[0033] When working, the accelerated gas strongly pushes the push bars 134 on the outer side surface of the transmission rod 133, and the transmission rod 133 drives the counterweight ring 135 to move up at the same time. Since the gravity center of the counterweight ring 135 is below, the difference between the surface of the counterweight ring 135 and the transmission rod 133 causes the counterweight ring 135 and the vertical plate 136 to descend. Since the gravity center of the swing bar 137 is at the far end, the connection between the swing bar 137 and the vertical plate 136 is deformed during the descent of the vertical plate 136. The deformed swing bar 137 causes the oil inside to fluctuate, thereby stirring and pushing the oil, discharging the residual heat inside the oil, and increasing the diffusion of the residual heat of the oil.

[0034] Working principle: the oil-water mixture is guided into the inside of the oil-water separation tank 12, and the oil and water are allowed to stand in the inside of the oil-water separation tank 12. The density difference between the oil and the water allows the oil to naturally float to the water surface, thereby achieving separation. After the oil and water are separated, if the water source is higher than the top horizontal line 121, the closed plate 129 is rotated at this time to remove the blockage at the entrance of the water outlet 127. The unblocked water outlet 127 allows the water source at the bottom of the oil-water separation tank 12 to quickly pass through the water outlet 127 and enter the inside of the drain pipe 1210, thereby discharging the excess water source and reducing the water source in the oil-water separation tank 12 to avoid the effect of too much water source.

[0035] When the water source is continuously discharged and reaches the bottom horizontal line 121, the water outlet 127 is closed to stop the continuous discharge of the water source. The overlap support plate 123 is lifted by the hydraulic rod 122 to open the entrance of the water inlet 124, and the oil separated from the inside of the oil-water separation tank 12 is guided into the inside of the mixing plate 125 through the water inlet 124, and the oil is concentrated in the oil storage tank 11. When the height of the oil is lower than the water inlet 124, the oil-water mixture is injected into the inside of the oil-water separation tank 12 again, and the inside of the oil-water separation tank 12 is refilled with the oil-water mixture, and the oil and water are naturally separated again.

[0036] At this time, the high-pressure fan 131 is matched to infuse gas into the inside of the cooling hollow slab 13, the horn mouth 132 is used to compress the large amount of gas infused by the high-pressure fan 131, and the compressed gas flows into the inside of the cooling hollow slab 13, the internal air pressure of the gas after being compressed is increased, the flow of the gas is accelerated under the pushing of the subsequent gas, the fast-flowing gas can take away the residual heat on the surface of the cooling hollow slab 13, the oil in the inside of the oil storage tank 11 can be kept in a low-temperature state, the surface of the oil storage tank 11 is prevented from generating an excessively high heat source due to the irradiation of external sunlight, the oil is prevented from being gasified to generate harmful gas, and the effect of increasing the internal air pressure of the oil storage tank 11 is achieved.

[0037] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
