[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] Embodiment 1, as Figure 1-5 As shown, the utility model provides a metal corrugated oil storage cabinet for a transformer, comprising: a cabinet body 1, with scale plates 2 fixedly embedded at both ends of the cabinet body 1, and also comprising:

[0030] A plurality of hollow rods are fixedly mounted on the inner surface of the cabinet away from the scale plate;

[0031] Two metal corrugated cores are fixedly mounted on one end of the cabinet body close to the hollow rod;

[0032] Two sliding plates are respectively fixedly mounted on one end of the two metal corrugated cores away from the bottom of the cabinet;

[0033] Two balancing rods are respectively fixedly mounted on one side of the two sliding plates away from the two metal corrugated cores;

[0034] Two indicator needles are respectively fixedly installed on one side of the two balance bars close to the two scale plates. The two indicator needles 901 move vertically between the two scale plates 2. Multiple fixed blocks 602 are fixedly installed on one side of the two sliding plates 601 close to the two balance bars 9. Multiple fixed blocks 602 are fixedly installed on one side of the two balance bars 9 close to the two sliding plates 601. A fixed plate 101 is fixedly installed on one end of the cabinet 1 close to one of the scale plates 2. A camera 4 is fixedly installed on one side of the fixed plate 101 close to the scale plate 2. The camera 4 is wirelessly connected to an external monitoring display.

[0035] In this embodiment, when in use, after the cabinet 1 is installed, the external power supply is turned on. When the two metal corrugated cores 6 inside the cabinet 1 are working, they move vertically. The metal corrugated core 6 drives the sliding plate 601 to move up and down on the hollow rod 7, which is convenient for avoiding the metal corrugated core 6 from tilting and deforming when moving, which is beneficial to improving the stability of the utility model when working. The sliding plate 601 drives the fixed block 602 and the balance bar 9 to move up and down. When the balance bar 9 moves, it drives the indicator needle 901 and the counterweight block 902 to move up and down. At the same time, when the indicator needle 901 moves up and down, it compares with the scale plate 2 to achieve the effect of displaying the real-time data of the oil level. At the same time, a camera 4 is arranged on the fixed plate 101 to monitor the indicator needle 901 on the scale plate 2 in real time, which is beneficial for transmitting the monitoring picture to the monitoring display in front of the staff in real time through wireless technology, so as to facilitate the staff to observe in real time.

[0036] Embodiment 2, as Figure 1-5 As shown, a connecting pipe 10 is fixedly installed at one end of the two metal corrugated cores 6 close to the top of the cabinet 1, and one end of the connecting pipe 10 away from the two metal corrugated cores 6 is respectively fixedly installed on the inner surfaces of two sliding plates 601 and two balance bars 9, and a plurality of counterweights 902 are fixedly installed at one end of the two balance bars 9 away from the two scale plates 2. A fixing frame 8 is fixedly installed on the inner surface of the cabinet 1 close to the plurality of counterweights 902, and a plurality of mounting plates 801 are fixedly installed on both sides of the fixing frame 8 close to the two balance bars 9. Pressure sensors 802 are fixedly installed on one side of the plurality of mounting plates 801 close to the balance bars 9, and the plurality of pressure sensors 802 are respectively located on the same axis as the plurality of counterweights 902. An audible and visual alarm 3 is fixedly installed at one end of the cabinet 1 away from the scale plate 2, and the audible and visual alarm 3 is respectively electrically connected to the plurality of pressure sensors 802. An external pipe 5 is fixedly connected to one end of the two metal corrugated cores 6 away from the connecting pipe 10, and the external pipe 5 runs through the cabinet 1 and extends to the outside.

[0037] In this embodiment, when in use, a counterweight 902 is provided at the other end of the balance bar 9 to compensate for the weight of the indicator needle 901. A mounting plate 801 is provided on the fixed frame 8. When the counterweight 902 moves synchronously with the balance bar 9, when the counterweight 902 touches the pressure sensor 802 on the mounting plate 801, an extrusion force is generated on the pressure sensor 802, prompting the pressure sensor 802 to generate an electrical signal, which is transmitted to the sound and light alarm 3. Then the sound and light alarm 3 works, emitting an alarm sound and flashing light, which is helpful to remind the staff, and cooperate with the camera 4 to check whether the equipment is at a high oil level or a low oil level, so that the staff can make corresponding control operations. The two metal corrugated cores 6 are connected through the connecting pipe 10 and connected to the external oil supply pipeline through the external pipeline 5.

[0038] Working principle: When in use, after the cabinet 1 is installed, the external power supply is turned on. When the two metal corrugated cores 6 inside the cabinet 1 are working, they move vertically. The metal corrugated core 6 drives the sliding plate 601 to move up and down on the hollow rod 7, so as to avoid the metal corrugated core 6 from tilting and deforming when moving, which is beneficial to improve the stability of the utility model when working. The sliding plate 601 drives the fixed block 602 and the balance bar 9 to move up and down. When the balance bar 9 moves, it drives the indicator needle 901 and the counterweight block 902 to move up and down. At the same time, when the indicator needle 901 moves up and down, it compares with the scale plate 2 to achieve the effect of displaying the real-time data of the oil level. At the same time, a camera 4 is arranged on the fixed plate 101 to monitor the indicator needle 901 on the scale plate 2 in real time, which is beneficial to transmit the monitoring picture to the real-time monitoring device via wireless technology. The monitoring display in front of the staff is convenient for the staff to observe in real time. When in use, a counterweight 902 is set at the other end of the balance bar 9 to compensate for the weight of the indicator needle 901. A mounting plate 801 is set on the fixed frame 8. When the counterweight 902 moves synchronously with the balance bar 9, when the counterweight 902 touches the pressure sensor 802 on the mounting plate 801, it will generate an extrusion force on the pressure sensor 802, prompting the pressure sensor 802 to generate an electrical signal, which is transmitted to the sound and light alarm 3, and then the sound and light alarm 3 works, emitting an alarm sound and flashing light, which is helpful to remind the staff, and cooperate with the camera 4 to check whether the equipment is at a high oil level or a low oil level, so that the staff can make corresponding control operations. The two metal corrugated cores 6 are connected through the connecting pipe 10 and connected to the external oil supply pipeline through the external pipeline 5.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
