Description

Technical Field

[0001] The present invention relates to the field of transformer refueling, and more particularly to a convenient transformer refueling device. Background Art

[0002] The transformer principle of voltage transformation was first discovered by Faraday, but it was not put into practical use until the 1880s. In the competition between power plants that should output direct current and alternating current, one of the advantages of alternating current is that it can use transformers. Transformers can convert electrical energy into high voltage and low current forms, and then convert it back. This greatly reduces the loss of electrical energy during transmission, making the economic transmission distance of electrical energy longer. In this way, power plants can be built far away from places where electricity is consumed. Most of the world's electricity finally reaches the user after a series of transformations, and the maintenance and repair of transformers are naturally inseparable from refueling devices.

[0003] Currently, the method of refueling transformers is relatively simple. It requires manual climbing up the transformer to refuel. Climbing up and down the transformer with an oil drum weighing more than 10 kilograms brings great safety risks. Summary of the Invention

[0029] according to Figure 5-7 The convenient transformer refueling device shown includes a base 1, a top end of which is fixedly mounted an oil storage tank 2 for storing oil, and a side of which is fixedly mounted a storage box 3;

[0030] The storage box 3 contains a delivery hose 32, and one end of the delivery hose 32 is fixedly connected to the refueling pipe 4, and the other end of the delivery hose 32 is connected to the inside of the oil storage tank 2. The air pump 21 is fixedly installed on the other side of the oil storage tank 2;

[0031] One end of the refueling pipe 4 is provided with a fixing assembly, and the refueling pipe 4 is fixed by the fixing assembly.

[0032] In a preferred embodiment, Figure 1 As shown, a mounting frame 11 is fixedly mounted on the top of the base 1 on one side of the oil tank 2 , and a mounting groove matching the refueling pipe 4 is provided inside the mounting frame 11 . When in use, the refueling pipe 4 is taken out from the mounting frame 11 .

[0033] In a preferred embodiment, Figure 6As shown, the fixing assembly includes a fixing assembly 42 fixedly mounted on the fuel filling pipe 4, one end of the fuel filling pipe 4 is fixedly mounted on a connecting plate 42, the outer surface of the connecting plate 42 is provided with a slide groove 44, and the outer surface of the connecting plate 42 is located on one side of the slide groove 44 and a clamping plate 43 is provided. The clamping plate 43 is in the shape of an arc, and the inner side of the clamping plate 43 is provided with friction stripes. One end of the clamping plate 43 is fixedly mounted on a slider 45, and the slider 45 is arranged inside the slide groove 44, and the slider 45 is slidably connected to the connecting plate 42 through the slide groove 44. Knobs 46 are inserted around the outer surface of the connecting plate 42, and the knobs 46 are threadedly connected to the connecting plate 42. One end of the knob 46 is rotatably connected to the outer surface of the slider 45, and the knobs 46 around the connecting plate 42 are rotated to push the clamping plate 43 inward, and the slider 45 at one end of the clamping plate 43 slides inward along the slide groove 44, and the fuel filling pipe 4 is fixed by clamping the clamping plate 43 to the fuel tank opening.

[0034] In a preferred embodiment, Figure 7 As shown, the other end of the refueling pipe 4 is integrally connected to a nozzle 41, and a filter element 47 is provided at one end inside the nozzle 41. A filter disc 48 is fixedly installed at one end inside the filter element 47, and filtering is performed through the filter element 47 inside one end of the nozzle 41 and the filter disc 48 on the filter element 47.

[0035] In a preferred embodiment, Figure 7 As shown, one end of the filter element 47 is integrally connected with a retaining ring 471, and the other end of the filter element 47 is fixedly installed with a limiting plate 473. A through hole 472 is provided on the outer surface of one end of the filter element 47, and a reset spring 49 is provided on the outer surface of the filter element 47 on one side of the retaining ring 471. The filter element 47 is pushed outward by the hydraulic pressure to open the through hole 472 at one end of the filter element 47, and the engine oil is sprayed out through the through hole 472. In the process of the filter element 47 being pushed outward, the retaining ring 471 will squeeze the reset spring 49.

[0036] The specific implementation method is as follows: when in use, the refueling pipe 4 is taken out from the mounting frame 11, and at the same time, the delivery hose 32 is pulled out from the storage box 3, and the refueling pipe 4 is inserted into the oil tank of the transformer. The refueling pipe 4 is made of insulating material, which increases the safety of workers during operation. After the refueling pipe 4 is inserted, the knobs 46 around the connecting plate 42 are turned, and the knobs 46 are pushed inward to push the clamping plate 43. The slider 45 at one end of the clamping plate 43 slides inward along the slide groove 44. By clamping the clamping plate 43 to the oil tank opening, the refueling pipe 4 is fixed, and then the air pump 21 on one side of the oil storage tank 2 is started to transport the internal engine oil from the delivery hose 32 to the refueling pipe 4. The oil is then filtered through the filter element 47 at one end of the nozzle 41 and the filter disc 48 on the filter element 47. At the same time, the filter element 47 is pushed outward by the hydraulic pressure to open the through hole 472 at one end of the filter element 47, and the engine oil is sprayed out through the through hole 472. In the process of the filter element 47 being pushed outward, the retaining ring 471 squeezes the return spring 49. When refueling is completed, the air pump 21 stops working and stops delivering the engine oil. After the filter element 47 loses the hydraulic push, the return spring 49 pushes the filter element 47 inward, pulls the filter element 47 back into the nozzle 41, closes the through hole 472 at one end, and prevents the engine oil in the refueling pipe 4 from flowing out.

[0037] according to Figure 1-4 A convenient transformer refueling device is shown. Further, a rotating shaft 31 is horizontally arranged at the inner center of the storage box 3, and the rotating shaft 31 is rotatably connected to the storage box 3. The delivery hose 32 is rolled up on the outer surface of the rotating shaft 31. After use, the delivery hose 32 is rolled up on the rotating shaft 31.

[0038] In a preferred embodiment, Figure 3-4 As shown, a limiting component is provided on the outer surface of one side of the storage box 3, and the rotating shaft 31 is limited and fixed by the limiting component. The limiting component includes a turntable 33 provided on the outer surface of one side of the storage box 3, and a connecting tube 35 is provided inside one side of the turntable 33, and one end of the connecting tube 35 is fixedly connected to one end of the rotating shaft 31, and a sliding rod 36 is provided inside the connecting tube 35, and the sliding rod 36 is slidably connected to the connecting tube 35, and a baffle 37 is fixedly installed on one end of the sliding rod 36, and the other end of the sliding rod 36 is fixedly connected to the inner wall of the turntable 33. First, pull the turntable 33 outward to drive the sliding rod 36 to slide along the connecting tube 35, and at the same time, one end of the turntable 33 is detached from the chuck 34.

[0039] In a preferred embodiment, Figure 3-4As shown, a chuck 34 is fixedly mounted on the outer surface of one side of the storage box 3, and the turntable 33 is sleeved on the outer surface of the chuck 34. The outer surface of the chuck 34 is provided with teeth around it, and a slot matching the chuck 34 is provided on the outer surface of one end of the turntable 33. When a sufficient length is released, the turntable 33 is pushed inward to reset so that one end of the turntable 33 is re-sleeved on the chuck 34, limiting the position of the turntable 34 and thus fixing the turntable 33.

[0040] The specific implementation method is as follows: during use, before pulling out the delivery hose 32, it is necessary to first pull the turntable 33 outward to drive the slide bar 36 to slide along the connecting tube 35. At the same time, one end of the turntable 33 disengages from the chuck 34, releasing the limit on the turntable 33, and then rotate the turntable 33 to drive the internal rotating shaft 31 to rotate through the connecting tube 35 to release the delivery hose 32 from the opening at the bottom. When a sufficient length is released, the turntable 33 is pushed inward to reset, so that one end of the turntable 33 is re-mounted on the chuck 34, and the turntable 34 is limited, thereby fixing the turntable 33. After use, the delivery hose 32 is rolled up on the rotating shaft 31, and then the refueling pipe 4 is inserted into the mounting frame 11, thereby reducing the space occupied by the device and facilitating portability.

[0041] Working principle of the present invention:

[0042] Refer to the instruction manual Figure 5-6 When in use, take the filling pipe 4 out of the mounting bracket 11, and at the same time pull the delivery hose 32 out of the storage box 3, and insert the filling pipe 4 into the oil tank of the transformer. After the filling pipe 4 is inserted, fix the filling pipe 4 by clamping the splint 43 to the oil tank opening, and then start the air pump 21 on one side of the oil storage tank 2 to deliver the internal engine oil from the delivery hose 32 to the filling pipe 4. The filter element 47 is pushed outward by the hydraulic pressure to open the through hole 472 at one end of the filter element 47, and the engine oil is sprayed out through the through hole 472. When refueling is completed, the air pump 21 stops working and stops delivering the engine oil. After the filter element 47 loses the hydraulic pressure, the return spring 49 pushes the filter element 47 inward, pulls the filter element 47 back into the nozzle 41, closes the through hole 472 at one end, and prevents the engine oil in the filling pipe 4 from flowing out.

[0043] Refer to the instruction manual Figure 1-4After the delivery hose 32 is pulled out, the rotary disk 33 is pulled outwards to drive the slide bar 36 to slide along the connecting tube 35. At the same time, one end of the rotary disk 33 is disengaged from the chuck 34, releasing the limit of the rotary disk 33. Then the rotary disk 33 is rotated to drive the internal rotating shaft 31 to rotate through the connecting tube 35, and the delivery hose 32 is released from the opening at the bottom. When a sufficient length is released, the rotary disk 33 is pushed inwards to reset, so that one end of the rotary disk 33 is re-mounted on the chuck 34, and the rotary disk 34 is limited, thereby fixing the rotary disk 33. After use, the delivery hose 32 is rewound on the rotating shaft 31, and then the refueling pipe 4 is inserted into the mounting frame 11, thereby reducing the space occupied by the device and facilitating portability.
