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

Abstract

Disclosed are a fuel tank anti-theft apparatus and an anti-theft fuel tank equipped with the fuel tank anti-theft apparatus. The fuel tank anti-theft apparatus is provided on a fuel tank fuel filling port for preventing theft of fuel from the fuel tank fuel filling port. The fuel tank anti-theft apparatus comprises: a box body (1), with at least one first filter mesh (12) provided on at least one side wall of the box body (1); a fuel filling pipe (2) extending from the top face of the box body (1) to the outside of the box body (1), one end of the fuel filling pipe (2) being provided with a top cap (22) able to be detached and the other end of the fuel filling pipe (2) being connected to the box body (1). The interiors of the fuel filling pipe (2) and the box body (1) are in communication, the inside of the pipe body of the fuel filling pipe (2) being provided in a detachable fashion with a second filter mesh (23). Fuel is filled from the end of the fuel filling pipe (2) provided with the top cap (22), passes through the second filter mesh (23) and then flows into the box body (1), and passes through the first filter mesh (12) to enter the fuel tank. The fuel tank anti-theft apparatus and the anti-theft fuel tank equipped with the fuel tank anti-theft apparatus can both prevent theft and filter at the same time as ensuring ease of maintenance.

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 equipped with the fuel tank anti-theft device. Prevent others from stealing fuel from the fuel tank through the filling port. Background technique [0002] Some mechanical equipment with fuel tanks, especially those that need to be frequently operated in the field or berthed in the field, and some power generation equipment with fuel tanks that need to be operated in the field, such as generators, cars, construction machinery etc., it is necessary to frequently replenish fuel to its fuel tank, and the process of replenishing fuel needs to consider filtering out particles or other impurities in the fuel added, so as to facilitate the normal operation of the equipment. In addition, when these devices are left unattended in the field, considerations need to be taken to prevent others from stealing fuel from the fuel tank throug...

AI Technical Summary

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
