Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a safety protection device for transformers used in power grid construction. Background Technology

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to change the voltage and current of alternating current (AC). Its core functions are to transmit electrical energy, transform voltage, provide electrical isolation, and match impedance. Transformers are required during power grid construction, and they are protected by being housed in cabinets.

[0003] A search revealed a Chinese patent with application number "CN202310754084.7", which specifically describes a transformer protection device. The device includes a housing with a top cover. Storage slots are formed on opposite side walls of the housing, and through holes are formed in the inner walls of these slots. A rotating rod is rotatably mounted within each slot, and a baffle plate is fixedly fitted onto the rotating rod. The baffle plate is rotatably connected to the storage slot, and a sensor is mounted on the outer wall of the baffle plate.

[0032] This invention provides the following technical solutions:

[0033] Example 1

[0034] Please see Figure 1 - Figure 9 A safety protection device for a transformer used in power grid construction includes a protective box 1 and a transformer body 4 disposed inside the protective box 1. Heat dissipation vents 5 are provided on both the left and right sides of the protective box 1. A protective unit 6 is provided on the outer side of the protective box 1.

The protective unit 6 includes multiple protective covers 61, which are fixedly connected to the outer side of the protective box 1 and located above and below the heat dissipation vents 5. A shielding component 62 is provided on the inner side of the protective cover 61 to shield the heat dissipation vents 5 and reduce the impact of dust on the transformer body 4. A base 3 is fixedly connected to the lower side of the protective box 1. Mounting holes are provided on the outer side of the base 3, which are bolted together to facilitate the installation of the protective box 1. The protective box 1 protects the transformer body 4. The upper terminals of the transformer body 4 extend from the upper side of the protective box 1 for easy wiring. The heat dissipation vents 5 facilitate heat dissipation from the transformer body 4.

[0035] The shielding assembly 62 includes a cover plate 623, which is disposed on the side of the protective cover 61 near the heat dissipation vent 5. A groove 624 is formed on the outer side of the cover plate 623, and a slider 625 is slidably connected to the inner side of the groove 624. A movable plate 626 is fixedly connected to the upper side of the slider 625. A shielding plate 627 is fixedly connected to the side of the movable plate 626 near the protective box 1. Sliding rods 6240 are fixedly connected to both the front and rear sides of the movable plate 626. Inclined grooves 621 are formed on both the front and rear inner walls of the protective cover 61. 40 is slidably connected to the inclined groove 621. Connecting plates 629 are fixedly connected to the rear sides of both upper and lower cover plates 623. Cover plates 623 are slidably connected to the protective box 1. A shielding plate 627 is slidably connected to the cover plate 623. The upper and lower inclined grooves 621 are symmetrically arranged. A rotating shaft 6212 is rotatably connected to the rear side of the protective box 1. A turntable 6213 is fixedly connected to the rear end of the rotating shaft 6212. Two rear blocks 6214 are fixedly connected to the outer side of the turntable 6213. An inclined plate 6214 is rotatably connected to the rear side of each rear block 6214. 6215, an L-shaped plate 6241 is fixedly connected to the outer side of the connecting plate 629, a fixing block 6210 is fixedly connected to the outer side of the L-shaped plate 6241, a connecting rod 6211 is fixedly connected to the outer side of the fixing block 6210, the connecting rod 6211 is rotatably connected to the inclined plate 6215, a turntable 6216 is fixedly connected to the outer side of the rotating shaft 6212, a rotating block 6217 is fixedly connected to the outer side of the turntable 6216, an inclined plate 6218 is rotatably connected to the rear side of the rotating block 6217, and the rear side of the protective box 1... A guide plate 6219 is fixedly connected, and a guide block 6220 is slidably connected to the outside of the guide plate 6219. An inclined plate 6218 is rotatably connected to the guide block 6220. An mounting block 6222 is fixedly connected to the rear side of the protective box 1. An electric push rod 6221 is fixedly connected between the mounting block 6222 and the guide block 6220. A rear cover 7 is fixedly connected to the rear side of the protective box 1. Rectangular holes are provided on both the left and right sides of the rear cover 7. A connecting plate 629 is slidably connected to the rectangular holes. The two inclined plates 6215 are arranged in parallel.

[0036] When it rains outside, the control electric push rod 6221 drives the guide block 6220 to move. The guide block 6220 drives the inclined plate 6218 to rotate. The inclined plate 6218 drives the turntable 6216 on the rotating block 6217 to rotate. The turntable 6216 drives the rotating shaft 6212 to rotate. The rotating shaft 6212 drives the turntable 6213 to rotate. The turntable 6213 drives the rear block 6214 to rotate. The rear block 6214 drives the inclined plate 6215 to rotate. The inclined plate 6215 drives the fixing block 6210 on the connecting rod 6211 to move. Since the two inclined plates 6215 are arranged in parallel, the control L-shaped plates 6241 on the upper and lower sides move closer to each other. The L-shaped plates 6241 drive the connecting plate 629 to move. The connecting plate 629 drives the cover plate 623 to move. The cover plates 623 on the upper and lower sides move closer to each other. As they approach each other, the cover plate 623 drives the moving plate 626 to move, and the moving plate 626 drives the shielding plate 627 to move. At the same time, the moving plate 626 drives the sliding rod 6240 to slide in the inclined groove 621, so that the moving plate 626 moves towards the protective box 1. The moving plate 626 drives the shielding plate 627 to move, so that the shielding plate 627 moves towards the heat dissipation vent 5 and towards the protective box 1. The shielding plates 627 on the upper and lower sides shield the heat dissipation vent 5. When it is not raining outside, the electric push rod 6221 is controlled to move in the opposite direction, so that the shielding plates 627 on both sides are located inside the protective cover 61. The cover plate 623 shields the lower opening of the protective cover 61, which facilitates the shielding plate 627 to be shielded and protected, and prevents the shielding plate 627 from being exposed to the outside and allowing dust to adhere to its outer surface.

[0037] A fixed frame 628 is fixedly connected to the other side of the movable plate 626. Two sets of guide plates 6225 are fixedly connected to the inner side of the fixed frame 628. Guide blocks 6226 are slidably connected to the outer side of the guide plates 6225. A stabilizing plate 6227 is fixedly connected to the outer side of the guide blocks 6226. A metal block 6228 is fixedly connected to the side of the two stabilizing plates 6227 near the inner wall of the fixed frame 628. A rotating block 6229 is fixedly connected to the other side of the stabilizing plate 6227. An inclined plate 6230 is rotatably connected to the outer side of the rotating block 6229. A rotating block 6231 is rotatably connected to the outer side of the inclined plate 6230. A control block 6232 is fixedly connected to the rear side of the rotating block 6231. The inner side of the fixed frame 628 is fixedly connected to the fixed frame 628. A side block 6233 is connected, and a telescopic rod 6234 and a spring 6235 are fixedly connected between the side block 6233 and the control block 6232. A control shaft 6236 is rotatably connected to the inner side of the fixed frame 628, and a cam 6239 is fixedly connected to the outer side of the control shaft 6236. The cam 6239 abuts against the control block 6232. A take-up roller 6237 is fixedly connected to the outer side of the control shaft 6236, and an elastic rope 6238 is wound around the outer side of the take-up roller 6237. A moving hole 6223 is opened on the upper side of the protective cover 61, and a moving block 6224 is slidably connected to the inner side of the moving hole 6223. The elastic rope 6238 is fixedly connected to the moving block 6224. A top cover 622 is fixedly connected to the outer side of the protective cover 61.

[0038] When the baffle plate 627 moves up and down, the moving plate 626 drives the fixed frame 628 to move up and down. Under the action of the elastic rope 6238, the elastic rope 6238 drives the winding roller 6237 to rotate. The winding roller 6237 drives the control shaft 6236 to rotate. The control shaft 6236 drives the cam 6239 to rotate. The cam 6239 drives the control block 6232 to move back and forth. The control block 6232 drives the inclined plate 6230 to rotate. The inclined plate 6230 drives the stabilizing plate 6227 to move. Since the two inclined plates 6230 are symmetrically distributed, the stabilizing plates 6227 on the upper and lower sides move repeatedly towards each other. The stabilizing plate 6227 drives the metal block 6228 to move, which facilitates the repeated impact of the metal block 6228 on the fixed frame 628, generating vibration and causing the baffle plate 627 to resonate. The dust on the surface of the baffle plate 627 is shaken off, preventing a lot of dust from splashing onto the surface of the transformer body 4.

[0039] Example 2

[0040] Based on Example 1, such as Figure 10 , Figure 11 As shown, an absorption assembly 63 is provided inside the protective box 1. The absorption assembly 63 includes side holes 631, which are located on the left and right sides of the protective box 1. Side covers 632 are fixedly connected to the left and right inner walls of the protective box 1. Connecting pipes 633 and concentrating pipes 635 are fixedly connected to the inner side of the side covers 632. Multiple adsorption heads 634 are fixedly connected to the outer side of the connecting pipes 633. Multiple connecting pipes 633 are provided, and the multiple connecting pipes 633 are connected to the concentrating pipes 635. The concentrating pipes 635 on the left and right sides are fixedly connected. A conveying pipe 636 is fixedly connected to the rear cover 7, and an air pump 638 is fixedly connected to the inside of the rear cover 7. A second conveying pipe 637 is fixedly connected between the air pump 638 and the first conveying pipe 636. The output end of the air pump 638 extends to the outside of the rear cover 7. When the dust on the surface of the baffle plate 627 is shaken off, the air pump 638 is activated. Under the action of the second conveying pipe 637, the first conveying pipe 636, the concentrator pipe 635 and the connecting pipe 633, multiple adsorption heads 634 absorb the dust to prevent dust accumulation from affecting the next use.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] Working Principle: During operation, the operator first controls the electric push rod 6221 to move the guide block 6220. Under the action of the inclined plate 6218, rotating block 6217, and turntable 6216, the rotating shaft 6212 is controlled to rotate. The rotating shaft 6212 drives the turntable 6213 to rotate. Under the action of the rear block 6214, inclined plate 6215, and connecting rod 6211, the fixed blocks 6210 on both sides are controlled to move closer together. The fixed blocks 6210 drive the L-shaped plate 6241 to move, the L-shaped plate 6241 drives the connecting plate 629 to move, and the connecting plate 629 drives the cover plate 623 to move. The cover plates 623 on both sides move closer together, and the cover plates 623 drive the moving plate 626 and the shielding plate 627 to move. Under the action of the inclined groove 621 and the sliding rod 6240, the shielding plate 627 is controlled to move towards the protective box 1, facilitating movement of the upper and lower sides. The baffle plate 627 blocks the heat dissipation vent 5. When rapid heat dissipation is needed, the electric push rod 6221 is moved in the reverse direction, so that the baffle plate 627 is located inside the protective cover 61, which facilitates the blocking and protection of the baffle plate 627 and prevents a lot of dust from adhering to the surface of the baffle plate 627. At the same time, under the action of the elastic rope 6238, the control shaft 6236 drives the cam 6239 to rotate. Under the action of the control block 6232, the inclined plate three 6230 and the stabilizing plate 6227, the metal block 6228 is controlled to move up and down repeatedly, so that the metal block 6228 can impact the fixed frame 628 and generate vibration. The resonance of the baffle plate 627 shakes the dust off the surface. At the same time, the air pump 638 is started. Under the action of the second conveying pipe 637, the first conveying pipe 636, the central pipe 635 and the connecting pipe 633, multiple suction heads 634 absorb the dust.
