Description
Technical Field
The invention relates to the technical field of oil tank anti-theft devices of large transport vehicles, in particular to an oil theft prevention structure for an oil tank.
Background
At present, trucks, especially medium and heavy trucks, are an important part of domestic logistics. Since the engine of a truck consumes a large amount of fuel and the truck needs to be transported over a long distance, the truck needs to be equipped with a large tank capacity and sometimes with a plurality of tanks. The large-capacity fuel tank in the truck is generally arranged on the side face of the vehicle and is not covered by a baffle plate, so that the problem of fuel oil theft is solved. Due to high fuel value, the fuel oil is seriously lost for the owner after being stolen.
Many fuel tanks designed for theft prevention currently prevent fuel from being stolen from the viewpoint of providing a barrier at a fuel tank filler opening, for example, as disclosed in patent documents CN201810360603.0 and CN 201910664207.1.
Patent document CN201910898961.1 discloses that by providing an outer box and an inner box sleeved in the outer box, the double-layer anti-theft oil tank is not easily damaged, thereby facilitating the repair of the double-layer anti-theft oil tank, and after the outer box is damaged, the inner box can still be used independently of the outer box.
Above technical scheme who prevents that the fuel is stolen all needs to carry out structural improvement to current oil tank, causes the cost to increase.
Patent documents such as CN202010022193.6, CN201510356319.2 and CN201310404324.7 disclose that the state of the fuel tank is monitored by installing a sensor, so that the fuel tank can give an alarm in time and prevent fuel from being stolen. The sensor can be directly arranged on the surface of the fuel tank or in the mailbox, and the structure of the existing fuel tank does not need to be changed or only needs to be changed to a small extent. The problem of adopting the sensor to monitor the oil tank state lies in that the sensor precision is too high and easily causes the false alarm, and the too low easily causes the false alarm. Solutions combining multiple sensors can solve the problem of false positives and false negatives to some extent, but in turn need to face high costs.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
Examples
This embodiment provides an oil theft prevention structure for oil tank, through with prevent stealing oily structrual installation on the oil tank, can play the stolen effect of fuel, need not to change current oil tank structure.
Referring to fig. 1, a fuel tank 300 of a truck according to the related art is fixedly connected to a vehicle body by a harness 101 and an L-shaped bracket 400. After drilling a hole in the housing of the oil tank 300 using a drilling tool, such as the drill bit 501 of the electric drill 500 of fig. 2, a passageway is drilled in the housing of the oil tank 300 using the reamer 502, and a hose is inserted into the passageway to steal oil.
The embodiment provides an oil theft prevention structure for an oil tank, comprising:
the outer cover 600 covers the oil tank 300 and covers the wall of the oil tank 300 to be protected. The surface of the outer cover 600 is bulged at a plurality of places. In this embodiment, the drums are arranged in a staggered manner, each row/column of drums and the rows/columns of drums on two adjacent sides of each row/column of drums are arranged in a concavo-convex staggered manner, the drums are provided with openings, and the inner edges of the openings are formed with sawtooth structures.
Specifically, in the present embodiment, crocodile-mouth-shaped openings are selected, and each row/column of crocodile-mouth-shaped openings is arranged in a concave-convex staggered manner with the adjacent rows/columns of crocodile-mouth-shaped openings on both sides, as shown in fig. 3; the hole pattern of the crocodile mouth type hole opening is provided with a raised herringbone pattern and a raised cross pattern, and most of the holes are punched in a numerical control manner.
The zigzag-shaped openings are preferably crocodile-mouth-shaped openings, and each row/column of crocodile-mouth-shaped openings are arranged in a concave-convex staggered mode with the row/column of crocodile-mouth-shaped openings on two adjacent sides. Crocodile mouth type openings are used in the prior art for anti-slip, are commonly referred to as crocodile mouth anti-slip plates, are suitable for use outdoors in sewage treatment, tap water, other industrial industries of power plants, and are also used for mechanical anti-slip and interior decoration anti-slip. The crocodile mouth type opening is applied to an oil stealing prevention structure of the oil tank and serves as an outer cover 600 covering the oil tank, when an oil thief drills the outer cover 600 by using an electric drill (comprising a drill bit and a reamer), the drill bit penetrates through the outer cover 600, but the tooth mouth of the crocodile mouth type opening enables the reamer to slip on the outer cover 600, the reamer 502 cannot be centered and cannot complete reaming, and the drill bit 501 is broken by the outer cover due to the fact that the reamer 502 cannot be centered, so that fuel oil is prevented from being stolen after the oil tank is drilled. Based on the foregoing description of the principles of operation, it is shown that the use of crocodile-mouth-type opening in the present invention produces the technical effect of slipping the underreamer. Compared with the prior art, the crocodile mouth type opening has the advantages that the crocodile mouth type opening is easy to slip; one uses the crocodile mouth type opening anti-skid characteristic, which is quite different and opposite. This "qualitative" change is not predictable or predictable to those skilled in the art in advance, and therefore the housing of the present invention comprising crocodile-mouth openings has unexpected technical effects.
