AI Technical Summary
During the refueling process of oil storage tanks at existing drilling sites, it is difficult and troublesome to remove the bolts on the manhole flange cover, and the refueling hole directly opened on the manhole cover cannot be rainproof or dustproof, resulting in construction inconvenience and safety hazards.
An anti-theft device is designed, which includes a fuel filler port threaded cap, a fuel filler port threaded pipe column, a manhole flange cover plate of an oil storage tank and an anti-theft lock. The anti-theft and protection of the fuel filler port are achieved through threaded connection and locking structure, simplifying the refueling operation.
It improves refueling efficiency, reduces labor intensity, adapts to the refueling needs of different oil pipes, and provides rain and dust protection functions, thereby improving the convenience and safety of construction.

Abstract
Description
Technical Field
[0001] The utility model relates to an anti-theft device, in particular to an anti-theft device for a refueling port of an oil storage tank at a drilling site. Background Art
[0002] Domestic oilfields commonly use tanker trucks to refuel tanks through manholes on the tanks. In practice, this often requires removing 16 bolts from the manhole flange cover, disassembling the manhole flange cover, and inserting the refueling pipe into the manhole to refuel. This is a difficult and laborious process, creating significant hassles and delays during construction.
[0003] In order to avoid the trouble of removing the bolts on the manhole flange cover, some units directly open a refueling hole on the manhole cover. However, this has a new defect that it cannot prevent rain and dust. Utility Model Content
[0004] The purpose of the utility model is to provide an anti-theft device for the refueling port of an oil storage tank at a drilling site, which has a simple structure, is easy to use, has high working efficiency, is suitable for refueling with different oil pipes of various tank trucks, and is anti-theft, so as to solve the problems in the prior art.
[0005] The technical solution of the utility model is: an anti-theft device for the oil tank filling port at a drilling site, the anti-theft device comprising a threaded cap for the filling port, a threaded pipe column for the filling port, a flange cover for the manhole of the oil tank and an anti-theft lock;
[0006] The fuel filler port threaded cap includes a nut and a cover plate, the nut and the cover plate are welded together, the fuel filler port threaded cap is threadedly connected to the fuel filler port threaded pipe column, the fuel filler port threaded pipe column is fixedly connected to the manhole flange cover of the oil storage tank, the fuel filler port threaded pipe column and the fuel filler port threaded cap are respectively welded with locking ears, and the locking ears are each provided with a circular hole, and the anti-theft lock passes through the locking ears on the fuel filler port threaded pipe column and the fuel filler port threaded cap and is locked.
[0007] The beneficial effects of the utility model are: simple structure, easy use, and high working efficiency. It can not only adapt to the refueling and theft prevention of different oil pipes of various tank trucks, but also play a role in rain and dust prevention, which greatly facilitates high-position refueling operations, improves refueling efficiency, and reduces labor intensity, and is welcomed by construction workers. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural diagram of the present utility model.
[0009] In the figure, 1 is the refueling hose, 2 is the refueling port threaded cap, 21 is the nut, 22 is the cover plate, 3 is the refueling port threaded pipe column, 4 is the lock ear, and 5 is the oil tank manhole flange cover. DETAILED DESCRIPTION
[0010] An anti-theft device for a fuel filler port of an oil storage tank at a drilling site, comprising a fuel filler port threaded cap 2, a fuel filler port threaded pipe column 3, a manhole flange cover plate 5 for the oil storage tank, and an anti-theft lock;
[0011] The fuel filler threaded cap 2 includes a nut 21 and a cover plate 22, and the nut 21 and the cover plate 22 are welded together. The fuel filler threaded cap 2 is threadedly connected to the fuel filler threaded pipe column 3, and the fuel filler threaded pipe column 3 is fixedly connected to the manhole flange cover plate 5 of the oil storage tank. The fuel filler threaded pipe column 3 and the fuel filler threaded cap 2 are respectively welded with locking ears 4, and the locking ears 4 are each provided with a circular hole. The anti-theft lock passes through the fuel filler threaded pipe column 4 and the locking ears 4 on the fuel filler threaded cap 3 and is locked.
[0012] The utility model is an anti-theft device for the filling pipe opening of an oil storage tank. The user only needs to open the anti-theft lock, unscrew the filling pipe cap 2, and refuel. After refueling, screw on the filling pipe cap 2 and lock the anti-theft lock. The device is simple and convenient. The threads on the filling pipe cap 2 and the filling pipe column 3 can even be removed. When refueling, the filling pipe cap 2 can be directly removed. After refueling, the filling pipe cap 2 can be replaced and locked with the anti-theft lock. This device is more convenient and practical.
