[0015] The present invention has the following beneficial effects:
[0016] 1. The oil drain valve anti-theft device for oil-immersed transformers uses an adjusting wheel and a ratchet wheel in cooperation, uses the adjusting wheel to drive the ratchet wheel to rotate forward, and a spring pushes the limit rod to drive the pawl to move downward, so that the inner wall of the outer edge of the ratchet wheel is connected with the outer edge of the pawl, and then the ratchet wheel drives the adjusting ring to rotate through the pawl, and then the ratchet wheel drives the four-way pipe two to rotate until the infrared receiver and the infrared transmitter signal are connected. At this time, the side of the electromagnet ring and the side of the fixed magnet ring are adsorbed, so that the connecting inner cylinder slides on the outer edge of the fixed ring two, and the connecting outer cylinder slides on the outer edge of the fixed ring one, until the outer edge of the connecting inner cylinder and the inner wall of the connecting outer cylinder are connected to the limit, and then the infrared receiver is driven to connect with the infrared transmitter to be connected by rotating the adjusting wheel at different positions, so that the internal pipeline of the auxiliary device is connected.
[0017] 2. The oil drain valve anti-theft device for oil-immersed transformer uses a ratchet and a pawl in cooperation. When the ratchet rotates forward, the ratchet drives the pawl to rotate. When the ratchet rotates reversely, the inner wall of the ratchet pushes the pawl upward, thereby preventing the adjusting ring from rotating with the ratchet, thereby further improving the safety of the device.
[0018] 3. The oil drain valve anti-theft device for oil-immersed transformer uses a docking auxiliary cylinder and an anti-theft cylinder. After the internal pipeline of the protection frame is adjusted, the docking auxiliary cylinder is docked with the internal pipeline of the device, so that the docking auxiliary cylinder is used to control the electromagnet plate to cut off the power, and then the tension spring is used to drive the electromagnet plate to move toward the inner wall of the slot, and the inner wall of the sliding frame is used to assist the electromagnet plate to move stably, so that the side of the convex plate moves away from the inner wall of the docking slot, thereby assisting the anti-theft cylinder to move away from the oil drain pipe, and then assisting the use of the oil drain pipe.
[0019] 4. The oil drain valve anti-theft device for oil-immersed transformers cooperates with the anti-theft cylinder through the use of the docking auxiliary cylinder. When the user forcibly opens the oil drain pipe, the outer edge of the fixed magnet plate pushes the electromagnet plate to move away from the inner wall of the slot, thereby driving the convex plate to move, and the side of the convex plate is used to dock with the inner wall of the docking groove to limit the position, thereby assisting the oil drain pipe to be stably limited. When the user forcibly drills a hole in the inner wall of the oil drain pipe, the internal oil of the device is limited inside the four-way pipe one, thereby preventing the user from stealing the internal oil outside the protection frame and the outside of the oil drain pipe.
[0020] 5. The oil drain valve anti-theft device for oil-immersed transformers uses an infrared receiver and an infrared transmitter in coordination, and uses infrared transmitters at different positions on the inner wall of the signal ring for opening and closing, thereby assisting the infrared receiver to open and close at different positions during rotation, and then assisting different transformers to adjust different pipeline positions, further improving the anti-theft effect of the device.
