[0015] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] See also Figure 1-2As shown, an innovative welded internal floating tank electrostatic lead-out connector comprises a metal outer shell 1, a conductive column 2, an electrostatic jumper wire 3, a terminal block 4, an insulating core 5, a clamping nut 6, a sealing gasket 7 and an electrostatic wire 8. The inner middle portion of the metal outer shell 1 and the insulating core 5 integrally cast with the conductive column 2 are sealed and fixedly connected to each other, and the outer middle portion of the metal outer shell 1 is sealed and welded to the structural part at the top of the tank body 11. The outer end of the conductive column 2 is connected to the terminal block 4 located at the outer end of the surface of the metal outer shell 1 through the electrostatic jumper wire 3, and the inner end of the conductive column 2 is connected to the connecting plate 9 through the electrostatic wire 8.

[0019] The metal outer shell 1 is symmetrically distributed in an even number on the top of the tank body 11; a sealing gasket 7 is provided between one side of the convex ring structure in the metal outer shell 1 and the bottom of the insulating core 5; a clamping nut 6 is installed in the external port of the metal outer shell 1, and a conductive column 2 part passes through the middle of the clamping nut 6; the bottom of the clamping nut 6 and the top surface of the insulating core 5 are pressed and contacted with each other; the connecting plates 9 are symmetrically distributed in an even number on the top of the tank body 11 and are installed on the floating plate 10, and the floating plate 10 is located in the tank body 11.

[0020] When the utility model is in use, by setting a conductive column 2 that runs through the inside and outside of the tank body 11, the method of increasing the electrical connection detection point outside the tank is conducive to realizing the method of detecting outside the tank, measuring the resistance value between the conductive column 2 and the tank body 11, and determining the connection state of the measured electrostatic conductor 8. The measurement is directly carried out outside the tank, first disconnecting the electrostatic jumper wire 3 between the outer end of the conductive column 2 and the terminal board 4 in one of its connectors, and measuring the resistance value between the conductive column 2 of the connector and the connecting board 9. If the resistance is less than or equal to the standard value, it can be determined that the electrostatic derivation electrical connection of the floating plate 10 in the tank body 11 is normal; if the resistance is greater than the standard value, it can be determined that the electrostatic derivation electrical connection of the floating plate 10 in the tank body 11 is abnormal;
