DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, the utility model of the real-time filtering device for oil of double-split oil-immersed power transformer for energy storage comprises a double-split oil-immersed power transformer body 1 and a pump body 2 connected to the double-split oil-immersed power transformer body 1; the pump body 2 comprises a first output end and a second output end, the first output end is connected to a filter 3 and two valves 4, the oil outlet end of the first output end is connected to the double-split oil-immersed power transformer body 1, and the two valves 4 are respectively located upstream and downstream of the filter 3;

[0023] The second output end is connected with a filter 2 5 and two valves 2 6, the oil outlet end of the second output end is connected with the double-split oil-immersed power transformer body 1, and the two valves 2 6 are respectively located upstream and downstream of the filter 2 5;

[0024] Both valve 1 4 and valve 2 6 are ball valves, and the opening and closing of the first output end or the second output end can be controlled by rotating the valve stem 90 degrees;

[0025] It also includes a lifting plate 7 that is slidably connected to the main body 1 of the double-split oil-immersed power transformer, and the lifting plate 7 is fixedly connected to a motor 8, and the output end of the motor 8 is a toothless gear 9;

[0026] The valve stem of one of the valves 1 4 is fixedly connected to the gear 2 10, and the valve stem of one of the valves 2 6 is fixedly connected to the gear 3 11. The gear 2 10 and the gear 3 11 are respectively located on both sides of the toothless gear 1 9, and when the toothless gear 1 9 rotates, it can mesh with the gear 2 10 and the gear 3 11;

[0027] Furthermore, the valve stems of the two valves 4 are both fixed with sprockets 12, and the two sprockets 12 are sleeved with chains 13;

[0028] Furthermore, the valve stems of the two valves 6 are both fixed with sprockets 14, and the two sprockets 12 are sleeved with chains 15;

[0029] In this embodiment, when the two valves 1 4 are closed at the same time, the two valves 2 6 are opened at the same time, the filter 1 3 can be cleaned, and the filter 2 5 can be filtered. When the filter 2 5 needs to be cleaned, the position of the lifting plate 7 is adjusted to make the toothless gear 1 9, the gear 2 10 and the gear 3 11 on the same horizontal plane, and then the motor 8 is turned on, the toothless gear 1 9 rotates counterclockwise, first driving the gear 2 10 to rotate, and with the cooperation of the sprocket 1 12 and the chain 1 13, the two valves 1 4 are opened. In the above process, the smooth surface of the toothless gear 1 9 passes through the gear 3 11, and will not drive the gear 3 11 to rotate;

[0030] Then the toothless gear 1 9 drives the gear 3 11 to rotate, and with the cooperation of the sprocket 2 14 and the chain 2 15, the two valves 2 6 are closed, switching the filter 2 5 to a state where it can be cleaned.

[0032] In this embodiment, the lifting mechanism 17 adopts an oil cylinder. By controlling the extension and retraction of the oil cylinder piston rod, the height of the lifting plate 7, the motor 8 and the toothless gear 9 can be controlled. When the toothless gear 9 is higher than the gear 1 and the gear 2 10, the state of the valve 1 4 and the valve 2 6 can be manually controlled, which is more convenient.

[0034] In this embodiment, when the lifting mechanism 17 is in motion, it drives the optical axis 18 to move along with the lifting plate 7, thereby improving the stability of the lifting plate 7 when it is lifted or lowered.

[0035] Furthermore, a reinforcing plate 19 is installed between the double-split oil-immersed power transformer body 1 and the fixing plate 16;

[0038] Furthermore, the valve stems of the two valves 2 6 are both fixed with hand wheels 2;

[0039] In this embodiment, the provision of hand wheel 1 20 and hand wheel 2 makes it more convenient for the operator to manually control the states of valve 1 4 and valve 2 6 .

[0040] The utility model discloses a real-time filtering device for oil of a double-split oil-immersed power transformer for energy storage. When the two valves 1 4 are closed at the same time, the two valves 2 6 are opened at the same time, the filter 1 3 can be cleaned, and the filter 2 5 can be filtered. When the filter 2 5 needs to be cleaned, the lifting mechanism 17 is operated to make the toothless gear 1 9, the gear 2 10 and the gear 3 11 on the same horizontal plane, and then the motor 8 is turned on, the toothless gear 1 9 rotates counterclockwise, first driving the gear 2 10 to rotate, and under the cooperation of the sprocket 1 12 and the chain 1 13, the two valves 1 4 are opened. In the above process, the smooth surface of the toothless gear 1 9 passes through the gear 3 11, and will not drive the gear 3 11 to rotate.

[0041] Then the toothless gear 1 9 drives the gear 3 11 to rotate, and with the cooperation of the sprocket 2 14 and the chain 2 15, the two valves 2 6 are closed, switching the filter 2 5 to a state where it can be cleaned.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
