Description

Technical Field

[0001] This utility model relates to the field of auxiliary mechanisms for oil-immersed transformers, specifically to an emergency oil drain pipe with an adjustable tilt angle. Background Technology

[0002] Oil-immersed transformers are required to have valves installed at the bottom of the oil tank. The main function of the valves is to drain oil from the transformer or to filter oil. When a transformer needs to drain oil, it usually indicates a malfunction, and in extremely urgent situations, the valve gates need to be opened quickly.

[0003] The valves are primarily made of cast iron. Operating outdoors for extended periods alongside transformers, they are exposed to rain, dust, and even corrosive substances, leading to rust. Over time, the rust worsens. When the rust reaches a certain level, it affects the valve's opening, and in severe cases, can cause it to jam. In emergencies, this can prevent the valve from opening properly or result in serious consequences.

[0004] The valve is typically installed vertically on the tank wall, not far from it. This means that when draining oil from the transformer, a flexible hose needs to be connected to the valve to drain the transformer oil. In an emergency, there is no time to install a hose. Opening the valve without a hose, under high pressure inside the tank, can cause transformer oil to gush out through the outlet, flowing outside the emergency oil sump, causing pollution and waste. Furthermore, operating transformers can reach temperatures of around 100°C; improper operation could lead to a safety accident. Utility Model Content

[0014] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0015] Example 1:

[0016] The adjustable tilt angle emergency oil drain pipe proposed in this embodiment includes a connecting pipe 1, an adjusting pipe 2, and a bursting oil drain pipe 3. The connecting pipe 1 has a predetermined working length and supporting force, and is connected to the transformer tank for corresponding connection and limiting operations. The adjusting pipe 2 is connected to the connecting pipe 1, has a predetermined working length and bending radius, and has predetermined deformation, for corresponding connection operations. The bursting oil drain pipe 3 is connected to the adjusting pipe 2, has a predetermined working length, and is provided with a strike-breaking opening of a predetermined working size. An acrylic glass 4 is provided at the strike-breaking opening of the bursting oil drain pipe 3, and the overall working size of the acrylic glass 4 is adapted to the size of the strike-breaking opening of the bursting oil drain pipe 3, thus covering the strike-breaking opening. In a further preferred embodiment, the strength of the acrylic glass 4 is calculated to meet the transformer pressure.

[0017] Example 2:

[0018] Based on Embodiment 1, the blasting oil outlet pipe 3 has a sealing gasket 6 and a flange 5 at the impact breakage opening, and the impact breakage opening is covered with plexiglass 4. The sealing gasket 6 and flange 5 are sequentially pressed onto the plexiglass 4 and connected to the blasting oil outlet pipe 3. The regulating pipe 2 is a flexible oil discharge pipe with a predetermined working length and bending radius, and one end is connected to the connecting pipe 1, and the other end is connected to the blasting oil outlet pipe 3. In a further preferred embodiment, the regulating pipe 2 can be any one of a high-pressure hose, hydraulic hose, wire-wound hose, or wire-braided hose, mainly possessing high temperature resistance and a certain degree of flexibility. Multiple sealing gaskets 6 can be placed at the connection surfaces of the plexiglass 4 and the blasting oil outlet pipe 3, and at the connection surfaces with the flange 5, to ensure overall sealing and prevent oil leakage. The connecting pipe 1 can be connected to the transformer oil tank by welding or bolting, and the sealing gasket 6 can also be used to enhance the sealing.

[0019] In an emergency, use a standard tool (window breaker) to strike the acrylic glass 4. Once the acrylic glass 4 is broken, the transformer oil will flow out. This method allows for quick and safe removal of transformer oil without wasting or contaminating it, thus maximizing the safety of the operators.

[0020] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
