[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figures 1 to 6 In the present invention, a transformer operation monitoring device includes a transformer body 1, the bottom of the transformer body 1 is fixedly connected with two symmetrically distributed legs 2, the bottom of the transformer body 1 is provided with a mounting groove 3, the interior of the mounting groove 3 is clamped with a mounting box 4, the interior of the mounting box 4 is installed with a monitoring controller 5, a noise sensor 6 and a noise pickup unit 7 are installed on the monitoring controller 5, a temperature sensor 8 is fixedly connected to the monitoring controller 5 through an elastic wire, the detection end face of the temperature sensor 8 is clamped to the transformer body 1, ear plates 9 are installed on both sides of the mounting box 4, the two ear plates 9 are installed with a pulling mechanism 10 that movably cooperates with the bottom of the transformer body 1, the two ear plates 9 are rotatably connected with rollers 11 on both sides, the opposite sides of the two legs 2 are installed with side positioning members 12 that cooperate with the rollers 11, an outer frame 13 is installed on the outer side of the transformer body 1, and active noise reduction mechanisms 14 are installed on the four columns of the outer frame 13.

[0020] In the present invention, the monitoring controller 5 is installed inside the installation box 4, and then the installation box 4 is installed inside the installation slot 3, and the temperature sensor 8 is snap-fitted onto the top surface of the installation slot 3. At this time, the tension mechanism 10 is used to push the installation box 4 upward to save effort and facilitate closing. When the installation box 4 and the installation slot 3 are completely merged, the side positioning members 12 on both sides respectively limit the two ear plates 9 vertically on both sides to achieve positioning installation. When disassembly is required, the side positioning member 12 on the left side is locked, and then the side positioning member 12 is pushed to both sides to separate from the ear plate 9. At this time, the entire installation box 4 slides downward under the action of gravity, and a part of the gravity is offset under the action of the tension mechanism 10, so that the installation box 4 slides down safely at a low speed, and disassembly is very convenient. After installation, the entire installation box 4 is located at the bottom of the transformer body 1, which is rainproof and sun-proof, and has a relatively low relative height for easy operation and maintenance.

[0021] When the equipment is running, the monitoring controller 5 controls the temperature sensor 8 to monitor and collect the operating temperature data of the transformer body 1, and uses the noise sensor 6 to monitor the equipment noise data. When the noise exceeds the set value, the noise pickup unit 7 is turned on to collect the main sound wave data of the noise, and then the monitoring controller 5 generates the data of the opposite wave and generates an electrical signal according to the collected sound wave data, and then plays the opposite wave sound wave through the playback device to offset the noise sound wave to achieve noise suppression, thereby achieving the advantages of the device being convenient and flexible in loading and unloading and maintenance, while improving the waterproof performance and service life, and actively suppressing the noise when it exceeds the standard to reduce noise pollution, solving the problem that the monitoring equipment in the prior art is installed inside the shell, and an opening and closing door is generally provided on the shell for easy maintenance, but since most transformers are placed outdoors, the poor waterproof effect easily causes the equipment to be damp, affecting the monitoring effect and the equipment life, and the operation is laborious during loading and unloading maintenance, and while monitoring the noise, since the equipment has different working noises at different room temperatures, it is difficult to effectively control the noise when it exceeds the standard.

[0022] See also Figure 4 and Figure 5 , wherein: the active noise reduction mechanism 14 includes a protrusion block 141 and two speaker units 142, the protrusion block 141 is fixedly mounted on the column of the outer frame 13, the two speaker units 142 are respectively mounted on both sides of the protrusion block 141, and the two speaker units 142 are parallel to the outer side surface of the transformer body 1.

[0023] In the present invention, the two speaker units 142 on the protruding block 141 play the audio of the anti-sound wave to counteract and suppress the noise, thereby actively reducing the noise.

[0024] See also Figure 4 , wherein: an arc cover 1411 is fixedly connected to the outer side of the protruding block 141, and the arc cover 1411 is a ninety-degree sector shape.

[0025] In the present invention, the speaker unit 142 is more concentrated by the arc-shaped cover 1411, thereby improving the effect of suppressing noise waves.

[0026] See also Figure 2 , wherein: the pulling mechanism 10 includes a vertical guide rod 101 and a vertical spring 102, the bottom end of the vertical guide rod 101 is fixedly connected to the ear plate 9, and the top end of the vertical guide rod 101 penetrates into the outer wall of the transformer body 1 and is elastically connected to it through the vertical spring 102.

[0027] In the present invention, the vertical spring 102 generates a pulling force on the vertical guide rod 101 to partially offset the gravity of the installation box 4, so that the installation box 4 can be lowered more smoothly during disassembly and can be installed and combined more labor-savingly.

[0028] See also Figure 2 , wherein: the side positioning member 12 includes two cross bars 121, a cross spring 122 and a side pressure block 123, one end of the two cross bars 121 passes through the interior of the support foot 2 and is slidably connected thereto, the other end of the cross bar 121 is fixedly connected to the side pressure block 123, and one side of the side pressure block 123 is elastically connected to the support foot 2 through the cross spring 122.

[0029] In the present invention, the side pressure block 123 is guided and stabilized by the cross bar 121, and the cross spring 122 generates a lateral thrust, so that the side pressure block 123 maintains an outward force tendency, and the positioning effect of the lug plate 9 is more stable.

[0030] See also Figure 2 , wherein: the top of the side pressing block 123 overlaps with the rotating roller 11, and the opposite sides of the two side pressing blocks 123 are both provided with inclined surfaces 1231.

[0031] In the present invention, when the two side pressure blocks 123 are relatively separated, the roller 11 rotates and descends along the two inclined surfaces 1231, thereby further offsetting the force of the installation box 4 descending. As the installation box 4 descends, the squeezing force on both sides increases, which facilitates positioning when the installation box 4 descends to a repairable height. The structure is more reasonable and the use is more flexible.

[0032] See also Figure 2 , wherein: a lock slot 21 is opened inside the left support leg 2, an end of the bottom cross bar 121 away from the side pressure block 123 extends to the inside of the lock slot 21, an L-shaped block 22 is installed inside the lock slot 21, and a lock head 23 for controlling the rotation of the L-shaped block 22 is installed at the bottom of the support leg 2.

[0033] In the present invention, the L-shaped block 22 is controlled by the lock head 23 to rotate 180 degrees in the lock groove 21, so that the cross bar 121 matched with it can be positioned to position the side pressure block 123 on the side, and lock it to prevent someone from directly opening the installation box 4, which has a protective effect.

[0034] See also Figure 2 and Figure 6 , wherein: two heat dissipation holes 41 are opened at the bottom of the installation box 4, and a dustproof net 42 is fixedly connected inside the heat dissipation holes 41.

[0035] In the present invention, the heat dissipation holes 41 cooperate with the dustproof net 42 to achieve air circulation inside the installation box 4 to prevent dust and dissipate heat.

[0036] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
