Description

Oil stealing prevention structure for oil tank

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. Because the fuel value is high, serious loss is caused to the vehicle owner after the vehicle is stolen.

At present, many fuel tanks designed for theft prevention prevent fuel from being stolen from the aspect of setting a barrier at a fuel tank filler opening, for example, technical solutions disclosed in patent documents CN201810360603.0 and CN 201910664207.1.

Patent document CN201910898961.1 sets an outer box and an inner box sleeved in the outer box, so that the double-layer anti-theft oil tank is not easy to be 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 CN202010022193.6, CN201510356319.2, and CN201310404324.7 disclose that the fuel tank status is monitored by installing sensors, so as to 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 the thief drills a hole in the casing of the fuel tank 300 using a drilling tool, for example, a drill bit 501 of a power drill 500 of fig. 2, drills a passage in the casing of the fuel tank 300 using a reamer 502, and inserts a hose into the passage to steal the 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 an oil tank and serves as a housing 600 which is covered outside the oil tank, when an oil thief drills the housing 600 by using an electric drill (comprising a drill bit and a reamer), the drill bit penetrates through the housing 600, but the teeth of the crocodile mouth type opening can cause the reamer to slip on the housing 600, the reamer 502 cannot be steady and cannot complete reaming, and the drill bit 501 is broken by the housing due to the fact that the reamer 502 cannot be steady, so that the oil can be 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-shaped opening anti-skid characteristic, and the two characteristics are quite different and opposite. Such "qualitative" variations are not predictable or inferred in advance by those skilled in the art, and therefore the housing of the present invention, which includes crocodile mouth openings, has unexpected technical effects.

Be equipped with tank cap business turn over hole 601 on dustcoat 600, the position of tank cap business turn over hole 601 corresponds with the position of the oil tank lid on oil tank 300, and the diameter of tank cap business turn over hole 601 is greater than the diameter of tank cap.

This prevents a tool, such as a screwdriver, from being inserted into the gap between the fuel cap and the fuel cap access hole 601 to pry the fuel cap open.

Install tool to lock among the prior art on the oil tank cap, the person of stealing oil can't unscrew the oil tank cap, can only pry the oil tank cap with the instrument and steal oil after destroying it, passes through in this application the fender structure is enclosed to the annular, it surpasss to enclose the length that the fender structure extends to the oil tank direction the lower edge of oil tank cap, like this unable use tools, for example the screwdriver, stretches into and pries among oil tank cap and the oil tank cap business turn over hole 601 clearance the oil tank cap.

A space is provided between the cover 600 and the fuel tank 300, and the fuel tank cap is partially higher than the cover 600 and partially lower than the cover 600. The cover 600 is attached to the fuel tank 300 by means of the location feature of the fuel tank cap at the corner of the fuel tank 300. The outer surface of the tank cap is higher than the cover 600 in the up-down direction and lower than the cover 600 in the left-right direction or is flush with the cover 600. When the oil tank is filled with oil, the left side and the right side of the oil tank cover can be rotated to form the oil tank cover.

The cover 600 is fixed to the oil tank 300 by a connecting member connected to the shoulder strap 101 and the L-shaped bracket 400, and the cover 600 is fixed to the connecting member.
