Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a leak-proof transformer oil tank. Background Technology

[0002] The oil tank is the outer shell of the transformer, containing the iron core and windings and filled with transformer oil, so that the iron core and windings are immersed in the oil. The transformer oil serves to insulate and dissipate heat.

[0003] According to a public notice regarding a leak-proof transformer oil tank (Announcement No.: CN218241525U), the aforementioned application not only facilitates the protection of the sealing ring but also improves the sealing effect of the oil tank. This solves the problem that existing transformer oil tanks, which lack any protective measures for the sealing ring, will age or deform due to high temperatures inside the oil tank and external factors after long-term use.

[0004] However, in actual use, when the transformer load increases, the oil temperature rises, the transformer oil expands, and the pressure relief is insufficient, the internal connection of the oil tank is prone to oil leakage due to air pressure damage, which reduces the safety of the transformer. In view of this, we propose a transformer oil tank that is leak-proof. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof transformer oil tank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof transformer tank, comprising a transformer body, an oil tank body fixedly mounted on the surface of the transformer body, a housing above the oil tank body, a connecting pipe fixedly connected to the arc surface of the oil tank body, an exhaust pipe fixedly mounted on the upper surface of the housing, an exhaust mechanism inside the housing, and a promoting mechanism inside the housing including:

[0007] A sealing cap is disposed above the connecting pipe. A movable groove is formed on the lower surface of the sealing cap. A telescopic spring is fixedly connected inside the movable groove, and a sealing ring is fixedly connected to the end of the telescopic spring.

[0008] A guide plate is fixedly installed on the upper surface of the sealing cover, and an elastic telescopic rod is fixedly connected to the inner wall of the box, with the guide plate fixedly connected to the end of the elastic telescopic rod.

[0009] Preferably, the promoting mechanism includes a connecting rod, which is disposed on the inner wall of the first elastic telescopic rod. The surface of the first elastic telescopic rod has a connecting hole. A connecting frame is fixedly connected to the end of the connecting rod away from the first elastic telescopic rod. The end of the connecting frame away from the connecting rod is fixedly connected to the second elastic telescopic rod. A stabilizing plate is fixed to the upper surface of the box. A sealing ball is fixedly connected to the movable end of the second elastic telescopic rod.

[0010] Preferably, the diameter of the outlet pipe is adapted to the diameter of the sealing ball, and the shape of the stabilizing plate is adapted to the shape of the elastic telescopic rod II, so that the sealing ball can seal the opening of the outlet pipe and ensure the stable movement of the elastic telescopic rod II.

[0011] Preferably, the surface of the telescopic cylinder of the first elastic telescopic rod is provided with a connecting hole, the diameter of the connecting hole being adapted to the diameter of the connecting rod, and the end of the telescopic rod of the first elastic telescopic rod away from the sealing block is fixedly connected to a connecting rod, so that the connecting rod can move under the influence of the movement of the first elastic telescopic rod.

[0012] Preferably, the shape of the movable groove is adapted to the shape of the sealing ring, so that the sealing ring seals the movable groove, thereby ensuring the sealing performance of the connecting pipe.

[0013] Preferably, the number of telescopic springs is set to several, and the several telescopic springs are evenly distributed in a circumferential array on the upper surface of the sealing ring. The telescopic springs stably compress the sealing ring to ensure the sealing performance.

[0014] Compared with the prior art, this utility model provides a leak-proof transformer oil tank, which has the following beneficial effects:

[0015] 1. This leak-proof transformer tank is equipped with a venting mechanism. The internal air pressure of the tank body compresses the sealing cover, causing it to lift and release gas. Simultaneously, the lifting of the sealing cover drives the guide plate to compress the sealing block, which in turn compresses the elastic telescopic rod, causing the sealing block to protrude through the venting port of the venting pipe for gas release. After the gas is released, the sealing cover falls down, compressing the telescopic spring and sealing ring to seal the connecting pipe, ensuring the airtightness of the tank body while meeting the pressure relief capacity. This prevents excessive internal pressure from damaging the tank body and causing oil leakage.

[0016] 2. This leak-proof transformer tank is equipped with a facilitating mechanism. During the movement of the first elastic telescopic rod, the connecting frame is squeezed, which in turn drives the sealing ball away from the outlet of the vent pipe to release air. After the air release is completed, the sealing ball returns to its original position and, under the action of the second elastic telescopic rod, adheres to the outlet of the vent pipe to ensure a seal and prevent dust from entering. This satisfies the pressure relief process, prevents oil leakage caused by damage to the inside of the tank body, and also prevents dust from entering the inside of the tank body.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a leak-proof transformer tank, including a transformer body 1, an oil tank body 2 fixedly installed on the surface of the transformer body 1, a tank 5 provided above the oil tank body 2, a connecting pipe 6 fixedly connected to the arc surface of the oil tank body 2, an exhaust pipe 7 fixedly installed on the upper surface of the tank 5, an exhaust mechanism 3 provided inside the tank 5, and a promotion mechanism 4 provided inside the tank 5, including a sealing cover 301, a movable groove 302, a sealing ring 304, a telescopic spring 305, a guide plate 306, a sealing block 307, and an elastic telescopic rod 308.

[0024] In one embodiment of this utility model, a sealing cover 301 is disposed above the connecting pipe 6. A movable groove 302 is provided on the lower surface of the sealing cover 301. A telescopic spring 305 is fixedly connected inside the movable groove 302. A sealing ring 304 is fixedly connected to the end of the telescopic spring 305. A guide plate 306 is fixedly installed on the upper surface of the sealing cover 301. An elastic telescopic rod 308 is fixedly connected to the inner wall of the housing 5. The guide plate 306 is fixedly connected to the end of the elastic telescopic rod 308.

[0025] In addition, the promoting mechanism 4 includes a connecting rod 401, which is disposed on the inner wall of the elastic telescopic rod 308. The surface of the elastic telescopic rod 308 has a connecting hole 402. A connecting frame 403 is fixedly connected to the end of the connecting rod 401 away from the elastic telescopic rod 308. The end of the connecting frame 403 away from the connecting rod 401 is fixedly connected to the elastic telescopic rod 404. A stabilizing plate 406 is fixedly fixed to the upper surface of the housing 5. A sealing ball 405 is fixedly connected to the movable end of the elastic telescopic rod 404. The diameter of the port of the air outlet pipe 7 is adapted to the diameter of the sealing ball 405. The shape of the stabilizing plate 406 is adapted to the shape of the elastic telescopic rod 404, so that the sealing ball 405 can seal the opening of the air outlet pipe 7 and ensure the stable movement of the elastic telescopic rod 404.

[0026] In this embodiment of the utility model, the surface of the telescopic cylinder of the elastic telescopic rod 308 is provided with a connecting hole 402. The diameter of the connecting hole 402 is adapted to the diameter of the connecting rod 401. The end of the telescopic rod of the elastic telescopic rod 308 away from the sealing block 307 is fixedly connected to the connecting rod 401, so that the connecting rod 401 moves under the influence of the movement of the elastic telescopic rod 308. The shape of the movable groove 302 is adapted to the shape of the sealing ring 304, so that the sealing ring 304 seals the movable groove 302, thereby ensuring the sealing performance of the connecting pipe 6. A number of telescopic springs 305 are provided, and the number of telescopic springs 305 are evenly distributed in a circumferential array on the upper surface of the sealing ring 304. The telescopic springs 305 stably compress the sealing ring 304 to ensure the sealing performance.

[0027] In this utility model, during use, the internal air pressure of the fuel tank body 2 squeezes the sealing cover 301 on the connecting pipe 6, lifting the sealing cover 301 and causing gas to overflow. At the same time as the sealing cover 301 is lifted, the guide plate 306 squeezes the sealing block 307, which in turn squeezes the elastic telescopic rod 308, causing the sealing block 307 to leak out of the air outlet of the air outlet pipe 7 for venting. Simultaneously, after the gas is released, the sealing cover 301 falls down, squeezing the telescopic spring 305 and the sealing ring 304 to seal the connecting pipe 6, preventing excessive internal pressure in the fuel tank body 2 from damaging the fuel tank body 2 and causing oil leakage.

[0028] Furthermore, during the movement of the elastic telescopic rod 308, it squeezes the connecting frame 403, thereby causing the sealing ball 405 to leave the opening of the vent pipe 7 for venting. After venting, the sealing ball 405 returns to its original position and, under the action of the elastic telescopic rod 404, adheres to the opening of the vent pipe 7 to ensure a seal, prevent dust from entering, and satisfy the pressure relief process. This prevents oil leakage caused by damage inside the oil tank body 2, while also preventing dust from entering the oil tank body 2.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
