As shown in fig. 2 and 9, the positioning mechanism 4 includes a positioning plate 41, damping springs 42, a positioning ring 43, and a through hole 44, the positioning plate 41 is fixedly connected to a central position of a lower surface of the poppet valve seat 2, the through hole 44 is formed on a lower end side surface of the positioning plate 41, six damping springs 42 are fixedly mounted on an inner surface of the through hole 44, and one end of each of the six damping springs 42 is commonly connected to the positioning ring 43.

According to the invention, by arranging the positioning mechanism 4 and utilizing the matching of the damping spring 42 and the positioning ring 43 with the drain pipe 5, when water flows through the drain pipe 5, the damping spring 42 is used for reducing the vibration frequency of the drain pipe 5, the phenomenon that the middle part of the drain pipe 5 is bent due to vibration in the drainage process is avoided, the service life of the drain pipe 5 is prolonged, and the cost is saved.

The using method comprises the following steps: during installation, the fixing plate 35 and the diversion plate 34 are fixed at the lower end of the opening of the lifting valve seat 2 through bolt connection, primary fixing between the drain pipe 5 and the water tank 31 is realized by utilizing the clamping action between the installation block 67 and the installation groove 69, the drain pipe 5 moves towards the water tank 31 during installation, the limiting block 641 is contacted with the fixing block 62 during installation, the limiting block 641 moves towards the blocking groove 66 due to the reaction force of the fixing block 62 to the limiting block 641, meanwhile, the limiting ball 65 rolls on the inclined surface of the limiting block 641, the inclined surface of the limiting block 641 enables the limiting ball 65 to protrude outwards and is fixedly matched with the limiting groove 68, the protruding limiting ball 65 is fixed inside the limiting groove 68 to prevent the limiting ball 65 from displacing, and the lower end of the drain pipe 5 penetrates through the positioning ring 43; when the device works, condensed water and transformer oil generated on the lifting valve seat 2 flow to the water storage tank 72 along the water guide plate 34, at the moment, the condensed water and the oil are mixed and stored in the water storage tank 72, the blocking ball 733 is in contact with the surface of the water guide plate 34 by utilizing the matching of the elastic force of the spring 732 and the blocking ball 733, so that one group of water storage tanks 72 are in a horizontal state with an upward opening, the water storage tanks 72 are convenient to receive and discharge water, when the gravity in the water storage tanks 72 does not meet the requirement, the spring 732 cannot be deformed, when the pressure applied by the water storage tanks 72 reaches the requirement of the deformation of the spring 732, the spring 732 is compressed, the blocking ball 733 is retracted into the shell 731, the restriction between the water storage tanks 72 and the water guide plate 34 is removed, the water storage tanks 72 are enabled to rotate smoothly, oil-water mixture in the water storage tanks 72 is discharged, and the next group of water storage tanks 72 are also kept in a horizontal state with an upward opening under the action of the blocking mechanism 73, so that one-time circulation is realized, the working efficiency is improved, oil-water mixture enters the water tank 31, when the liquid level in the water tank 31 reaches the highest point of the siphon pipeline 33, a siphon phenomenon of liquid can occur under the action of pressure difference between pipelines, liquid in the water tank 31 is discharged, the water tank 31 is emptied, in the drainage process, the floating ball 643 is pushed to deviate towards the direction of the drainage pipe 5 by the flowing of the liquid, the limiting block 641 is further clamped, the stability between the drainage pipe 5 and the fixing mechanism 6 is ensured, and the positioning mechanism 4 realizes the stability of the drainage pipe 5 in the drainage process by the aid of the matching of the damping spring 42 and the positioning ring 43.
