Anti-theft fuel drain port for locomotive fuel tank

Abstract

The invention discloses an anti-theft oil drain opening of a locomotive fuel tank. An oil drain opening which needs to be protected is formed in a fuel-tank end plate, and an annular screw holder is vertically welded to the outer side of the oil drain opening, on the fuel-tank end plate; an arc-shaped clamping plate is arranged on the outer side of the screw holder and vertically welded to the fuel-tank end plate; clamping plate holes are symmetrically formed in two free ends of the clamping plate; the minimum distance from each clamping plate hole to the fuel-tank end plate is larger than the height of the screw holder; a bowl-shaped cover plate is mounted in the arc-shaped clamping plate and concentric with the arc-shaped clamping plate; cover plate holes are respectively formed in positions corresponding to the clamping plate holes, in the bowl-shaped cover plate; a lock rod penetrates through the clamping plate holes and the cover plate holes; a lock rod head is arranged at one end of the lock rod, and the diameter of the lock rod head is larger than that of each clamping plate hole and that of each cover plate hole; a lock hole is formed in the other end of the lock rod; a lock is arranged in the lock hole; a screw plug is also arranged in the screw holder. The anti-theft oil drain opening is simple in structure, and convenient to mount, and can effectively prevent fuel from being stolen.

Description

technical field [0001] The invention relates to the field of locomotive fuel protection, in particular to an anti-theft oil drain port of a locomotive fuel tank. Background technique [0002] At present, the lower end of the fuel tank of the locomotive is equipped with a fuel oil discharge interface, but most of the interfaces are not protected against theft, and because the locomotive is parked in the open air most of the time, although there are patrol personnel, but Can't guarantee to keep an eye on at any time, often cause the event of fuel oil to be stolen like this to take place, and from the prior art, there is no anti-theft device at the fuel tank, so it is very necessary to develop a fuel drain with an anti-theft device. Contents of the invention [0003] The purpose of the present invention is to solve the problems of the prior art and provide an anti-theft oil drain port of the locomotive fuel tank, which has small volume, simple structure and convenient install...

AI Technical Summary

Problems solved by technology

[0002] At present, the lower end of the fuel tank of the locomotive is equipped with a fuel oil discharge interface, but most of the interfaces are not protected against theft, and the locomotive is in the open air most of the time when it is parked, although there are patrol personnel, but There is no guarantee of constant care, which often leads to fuel theft. However, according to the existing technology, there is no anti-theft device at the fuel tank, so it is very necessary to develop a fuel drain with an anti-theft device.
