Description

Technical Field

[0001] This utility model belongs to the field of transformer tank leak testing technology, and in particular relates to an American-style transformer tank leak testing device. Background Technology

[0002] American-style prefabricated transformer oil tanks are typically welded from high-strength steel plates, offering excellent sealing and mechanical strength. The tank interior is filled with insulating oil to cool the transformer and other electrical equipment, and to improve insulation performance. The tank design incorporates heat dissipation requirements, commonly employing corrugated tanks or finned structures to increase heat dissipation area. Some tanks are also equipped with oil level gauges, thermometers, and pressure relief devices for real-time monitoring of operating status. Furthermore, the tank surface undergoes anti-corrosion treatment to withstand harsh outdoor environments. The overall structure is compact, facilitating installation and maintenance, while meeting requirements for moisture and dust protection. Finished products undergo rigorous leak testing.

[0003] Comparing with Chinese Patent CN211121850U, an American-style transformer substation oil tank leak testing device is disclosed, including a housing, a pressure sensor, a central controller, and an air compressor. A support rod is fixedly connected to the upper surface of the housing. First drive motors are installed at both ends of the upper surface of the top plate. A sleeve welded to a connecting plate at the top passes through the interior of the first rubber pad. A vertical rod is installed inside the housing. A pressure sensor is embedded inside the outer surface of the inner plate. A second rubber pad is connected to the inner surface of the baffle. A second drive motor is fixed at the middle position of the outer surface of the adjusting plate. The air compressor is located on the left side of the housing, and a pressure gauge is installed on the right end of the upper surface of the housing. This device helps prevent air leakage from the air compressor or gaps in its installation, and also helps reduce the large amount of noise generated during inflation.

[0004] However, the aforementioned patent can only detect whether there is a leak, but cannot detect the specific location of the leak, making subsequent repairs difficult. Furthermore, it requires manual handling, which is time-consuming and labor-intensive. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an American-style transformer substation oil tank leak testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An American-style transformer substation oil tank leak testing device includes a clamping assembly for securing the oil tank, and a water tank assembly for immersion and inflation testing. A transfer assembly for moving and lifting the oil tank during immersion is located on one side of the water tank assembly, and the clamping assembly is positioned on top of the transfer assembly. The water tank assembly includes a water tank with four evenly distributed support legs at its bottom corners. A pressurizing mechanism for inflating and pressurizing the oil tank is installed at one end of the water tank. The transfer assembly includes a moving mechanism with two symmetrically mounted electric push rods at one end. A lifting frame is installed between the top ends of the electric push rods, and two cantilever frames are symmetrically arranged on one side of the lifting frame. The clamping assembly includes a lead screw with a servo motor at one end and a fixed gripper at the end of the lead screw away from the servo motor. A movable gripper is threadedly connected to the middle of the lead screw.

[0008] Furthermore, two clamping components are symmetrically arranged and are respectively installed on the bottom surfaces of the two cantilever frames.

[0009] Furthermore: a limiting sleeve is provided at the top of the movable gripper, the limiting sleeve is slidably connected to the cantilever frame, and the fixed gripper is bolted to the cantilever frame.

[0010] Furthermore, the fixed gripper and the movable gripper are respectively provided with limiting platforms on their opposite surfaces for positioning the oil tank.

[0011] Furthermore: the pressurization mechanism includes an air pump, an air delivery hose is installed on the air pump, and an air delivery connector is installed at the top of the air delivery hose.

[0012] Furthermore, a drain pipe is provided on one side of the water tank, and a drain valve is installed on the drain pipe.

[0013] Furthermore: the moving mechanism includes a walking frame, four walking motors are evenly installed at the four corners of the bottom of the walking frame, walking wheels are installed at the output end of the walking motors, and a storage battery is installed on the walking frame.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. By immersing the oil tank in a water tank assembly and pressurizing it with a booster mechanism, visible bubbles are formed at the leak point, making the detection intuitive and highly accurate, avoiding blind spots of traditional manual inspection; through the integrated design of automated clamping, transportation and immersion detection, the problem of low efficiency and poor accuracy of traditional oil tank leak detection is solved, which combines high efficiency, safety and easy maintenance, and is especially suitable for batch testing scenarios, with significant industrial application value;

[0016] 2. The transfer component enables automatic movement, lifting, and immersion of the oil tank. The clamping component uses a servo motor to drive the lead screw for precise clamping, which greatly improves the detection efficiency and reduces manual intervention. The clamping component (fixed / movable grippers), the transfer component (electric push rod + traveling wheels), and the water tank component (water tank + pressurization mechanism) work together to form a complete detection process with a compact structure and clear functions.

[0017] 3. The symmetrically designed dual clamping assembly is compatible with oil tanks of different sizes. The air supply connector of the pressurization mechanism can be flexibly connected to various interfaces, enhancing the versatility of the device. The clamping limit platform and limit sliding sleeve ensure accurate positioning of the oil tank and avoid clamping deviation. The support legs and walking frame provide a stable foundation to prevent tilting during operation. A closed loop is formed from clamping and inflation to water immersion detection, reducing the risk of missed detection due to human error. Attached Figure Description

Connect the fuel tank and immerse it in the water in the water tank 101. The air pump 105 pressurizes the fuel tank through the air hose 106. If there is a leak in the fuel tank, the compressed air will leak out from the leak point and form bubbles in the water, making it easy to locate the leak. If there is no leak in the fuel tank, reverse the above steps and remove the fuel tank. When the water in the water tank 101 becomes cloudy, open the drain valve 103 to drain the wastewater from the water tank 101 through the drain pipe 102, and then refill with clean water.

[0027] In this embodiment: the transfer component includes a moving mechanism, with two electric push rods 205 symmetrically installed at one end of the moving mechanism, and a lifting frame 206 installed between the top ends of the electric push rods 205. Two cantilever frames 207 are symmetrically arranged on one side of the lifting frame 206.
