Technical Field

[0001] The utility model relates to the technical field of seal detection, in particular to a seal performance detection device for a transformer oil tank. Background Technique

[0002] A transformer oil tank is a sealed and reliable container for storing transformer oil and other components of the transformer. It mainly consists of a tank body and a tank cover, usually made of steel plate, pressure vessel steel, stainless steel or aluminum alloy. The transformer oil tank should be kept sealed to avoid the influence of external pollution on the transformer oil. Therefore, it is necessary to detect the sealing performance of the transformer oil tank to prevent oil leakage.

[0003] At present, when detecting the sealing performance of a transformer oil tank, it is usually placed inside a water tank to observe whether there are bubbles inside the water tank to judge the sealing performance of the transformer oil tank. However, there is a lot of water remaining on the outer surface of the transformer oil tank after the detection, and the draining method is relatively slow. For this reason, we propose a seal performance detection device for a transformer oil tank. Content of the Utility Model

[0004] The purpose of the utility model is to provide a seal performance detection device for a transformer oil tank, which has the advantage of being convenient to quickly remove the water remaining on the surface after the sealing performance detection of the transformer oil tank, and solves the problem that when detecting the sealing performance of the current transformer oil tank, it is usually placed inside a water tank to observe whether there are bubbles inside the water tank to judge the sealing performance of the transformer oil tank, but there is a lot of water remaining on the outer surface of the transformer oil tank after the detection, and the draining method is relatively slow.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A seal performance detection device for a transformer oil tank, including a water tank, a hydraulic cylinder is fixedly installed at the middle position of the bottom inner wall of the water tank, a porous plate is fixedly connected to the output end of the hydraulic cylinder, a fixed frame is fixedly installed on the upper surface of the water tank, a rotating pipe is rotatably installed at the middle position of the lower surface of the fixed frame, an L-shaped pipe is fixedly connected to the lower surface of the rotating pipe, a plurality of air holes are equidistantly arranged on the outer surface of the L-shaped pipe, a transmission box is fixedly installed on the upper surface of the fixed frame, and the rotating pipe penetrates through the transmission box. An air pump is fixedly installed on one side of the upper surface of the fixed frame, and the end of the output pipe of the air pump is rotatably connected to the upper surface of the rotating pipe through a rotary joint.

[0006] Preferably, a rotating motor is fixedly installed on one side of the upper surface of the transmission box, a motor gear is fixedly connected to the end of the output shaft of the rotating motor, a transmission gear is fixedly sleeved on the outer surface of the rotating pipe, and the transmission gear meshes with the motor gear. Both the transmission gear and the motor gear are located inside the transmission box.

[0007] Preferably, a plurality of protrusions are evenly arranged on the upper surface of the porous plate.

[0008] Preferably, a through hole is provided on the outer surface of the porous plate. Sliding plates are slidably installed at both sides inside the through hole, and L-shaped plates are fixedly connected to one ends of the two sliding plates located outside the through hole. Right-angled trapezoidal blocks are symmetrically and fixedly installed at both sides inside the water tank.

[0009] Preferably, a spiral spring is arranged between the two sliding plates inside the through hole.

[0010] Preferably, anti-slip pads are fixedly installed at four corner positions close to the lower surface of the water tank.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing a water tank, a hydraulic cylinder, a porous plate, a fixing frame, an air pump, a rotating pipe, an L-shaped pipe, air outlet holes and a transmission box, the present utility model achieves the effect of facilitating the rapid removal of residual moisture on the surface of the transformer oil tank after the sealing performance detection of the transformer oil tank. The transformer oil tank is placed on the porous plate, and the hydraulic cylinder drives the porous plate to descend, so that the transformer oil tank enters the water tank. Whether bubbles appear inside the water tank is used to judge the sealing performance of the transformer oil tank. After the detection is completed, the hydraulic cylinder drives the porous plate to rise and reset. The rotating pipe drives the L-shaped pipe to rotate. At the same time, the air pump conveys high-pressure gas into the L-shaped pipe and blows it out from the air outlet holes to blow off the residual moisture on the outer surface of the transformer oil tank.

[0013] 2. By providing protrusions, the present utility model plays a role in supporting the transformer oil tank on the porous plate, so that there is a gap between the bottom of the transformer oil tank and the porous plate, which is convenient for the flow of water, and thus is conducive to draining the moisture at the bottom of the transformer oil tank.

[0014] 3. By providing a through hole, sliding plates, L-shaped plates and right-angled trapezoidal blocks, the present utility model achieves the effect of facilitating the fixation of the transformer oil tank during the sealing performance detection. The transformer oil tank is placed on the porous plate. When the hydraulic cylinder drives the porous plate to descend, the sliding plates contact the inclined surfaces of the right-angled trapezoidal blocks, which forces the two sliding plates to drive the two L-shaped plates to move towards each other, and finally the two L-shaped plates clamp and hook the two sides of the transformer oil tank.

[0015] 4. By providing a spiral spring, during the process of the porous plate rising and resetting, the compressed spiral spring is released, so that the two sliding plates drive the two L-shaped plates to move in the reverse direction, and the fixation of the transformer oil tank on the porous plate is released, which is convenient for taking away the transformer oil tank on the porous plate.

A number of protrusions 3 are evenly arranged on the upper surface of the porous plate 2. The protrusions 3 play a role in supporting the transformer oil tank on the porous plate 2, so that there is a gap between the bottom of the transformer oil tank and the porous plate 2, facilitating the flow of water, and thus being beneficial to draining the water at the bottom of the transformer oil tank. A fixing frame 4 is fixedly installed on the upper surface of the water tank 1.

[0024] At the middle position of the lower surface of the fixing frame 4, a rotating pipe 15 is rotatably installed.

A transmission box 13 is fixedly installed on the upper surface of the fixing frame 4, and the rotating pipe 15 penetrates through the transmission box 13. On one side of the upper surface of the transmission box 13, a rotating motor 12 is fixedly installed. The end of the output shaft of the rotating motor 12 is fixedly connected with a motor gear 14. A transmission gear 16 is fixedly sleeved on the outer surface of the rotating pipe 15, and the transmission gear 16 meshes with the motor gear 14. Both the transmission gear 16 and the motor gear 14 are located inside the transmission box 13. The rotating motor 12 drives the rotating pipe 15 to rotate through the meshed motor gear 14 and transmission gear 16. On one side of the upper surface of the fixing frame 4, an air pump 5 is fixedly installed, and the end of the output pipe of the air pump 5 is rotatably connected to the upper surface of the rotating pipe 15 through a rotary joint 11.

[0025] When the utility model is in use, the transformer oil tank is placed on the perforated plate 2. The hydraulic cylinder 9 drives the perforated plate 2 to descend, so that the transformer oil tank enters into the water tank 1. Whether bubbles appear inside the water tank 1 is used to judge the sealing performance of the transformer oil tank. After the detection is completed, the hydraulic cylinder 9 drives the perforated plate 2 to rise and reset. The rotating pipe 15 drives the L-shaped pipe 6 to rotate. At the same time, the air pump 5 conveys high-pressure gas into the L-shaped pipe 6 and blows it out from the air outlet holes 7 to blow off the moisture remaining on the outer surface of the transformer oil tank.

On both sides of the positions inside the through holes 20, sliding plates 19 are slidably installed. And at one end of the two sliding plates 19 located outside the through holes 20, L-shaped plates 18 are fixedly connected. On both sides of the inside of the water tank 1, right-angled trapezoidal blocks 8 are symmetrically and fixedly installed.

During the process of the perforated plate 2 rising and resetting, the compressed spiral spring 17 releases, so that the two sliding plates 19 drive the two L-shaped plates 18 to move in the opposite direction and release the fixation of the transformer oil tank on the perforated plate 2, which is convenient for taking away the transformer oil tank on the perforated plate 2.
