Oil tank anti-theft device and anti-theft oil tank

Abstract

The embodiment of the invention discloses an oil tank anti-theft device which is arranged on an oil filling port of an oil tank and is used for preventing fuel oil from being stolen from the oil filling port of the oil tank. The oil tank anti-theft device comprises a box body and an oil filling pipe, wherein the at least one first filter screen is arranged on at least one side wall of the box body; and the oil filling pipe stretches out of the box body from the upper top surface of the box body, one end of the oil filling pipe is provided with a detachable top cover, the other end of the oil filling pipe is connected with the box body, the interior of the oil filling pipe is communicated with that of the box body, a pipe body of the oil filling pipe is internally and detachably provided with a second filter screen, the fuel oil is filled from one end of the oil filling pipe, which is provided with the top cover, and then the fuel oil passes through the second filter screen to flow into the box body and passes through the first filter screen to flow into the oil tank. The invention also relates to an anti-theft oil tank which is provided with the oil tank anti-theft device. The oil tank of the oil tank anti-theft device and the anti-theft oil tank with the oil tank anti-theft device can realize theft prevention and filtration and can also ensure the maintenance simplicity.

Description

Technical field [0001] The present invention relates to the field of energy, in particular to a fuel tank anti-theft device and an anti-theft fuel tank with the fuel tank anti-theft device. On the one hand, the fuel tank anti-theft device can filter out particulate matter or other impurities in the fuel when refueling, and on the other hand can Prevent others from stealing fuel from the fuel tank through the fuel filler. Background technique [0002] Some mechanical equipment with fuel tanks, especially mechanical equipment that needs to be frequently operated in the field or need to be berthed in the wild, and some power generation equipment with fuel tanks that need to be operated in the field, such as generators, cars, construction machinery It is necessary to frequently replenish fuel into the fuel tank. The process of replenishing fuel needs to consider filtering out the particulate matter or other impurities in the fuel added to facilitate the normal operation of the equipm...

Problems solved by technology

[0004] However, although this fuel cap can prevent thieves from stealing fuel oil from the fuel port by welding the filter screen to a certain extent through the fuel cap with a lock, the fuel filter screen is generally Plastic mesh or barbed wire structure, which is easily damaged by sharp objects, in which case it is impossible to filter out particulate matter or other impurities present in the fuel being added

Moreover, the refueling filter screen adopted in the existing fuel filler is usually a special filter screen, and the general opening is very large, so it is difficult to play the role of filtering fuel impurities.

In addition, the filter screen and the flange are welded together on the fuel tank, so that once the filter screen is blocked, the filter screen cannot be easily taken out for cleaning, so maintenance is inconvenient
