Description

Technical Field

[0001] The utility model relates to the field of automobile oil tanks, and more specifically to an anti-theft device for a truck oil tank. Background Art

[0002] With the development of social economy, people's demand for logistics and express delivery industry is increasing. However, the anti-theft problem of truck fuel tanks still troubles truck drivers. Most truck fuel tanks are equipped with fuel tank locks on the tank opening to prevent fuel theft. This anti-theft method is not sensitive enough and cannot detect the theft of the fuel tank in time. The fuel in the fuel tank is easily stolen by illegal personnel.

[0003] Patent CN220594642U discloses a fuel tank anti-theft device for large trucks. When the drill bit contacts the fiber net, the fiber net will continuously entangle the drill bit, making it unable to continue to rotate, and preventing the drill bit from contacting the fuel tank. When replacing the limit net, screw the bolts to remove the cover plate, so that the connecting plate and the protective shell are fixed and welded, and then the fuel tank is taken out. The limit net can be replaced by using a hook to prevent criminals from drilling and stealing oil. Patent CN111873940A discloses the installation of an acceleration sensor and a strain sensor on the fuel tank bracket. The acceleration sensor monitors the vibration of the fuel tank bracket or the longitudinal beam of the frame in real time, and the strain sensor monitors the strain data of the fuel tank bracket in real time to sense the change in the amount of oil in the fuel tank; analyze the vibration monitored by the acceleration sensor and the strain data monitored by the strain sensor to determine whether an abnormality occurs, and issue an anti-theft alarm after an abnormality occurs. In addition, ultrasonic and video solutions are also used to monitor the situation near the fuel tank in real time.

[0004] When pedestrians pass by a truck, ultrasonic and video monitoring will generate false alarms, and in the long run the truck driver will turn off the quotation system; the solution disclosed in patent CN220594642U cannot provide real-time warning of theft; the solution disclosed in patent CN111873940A occurs after the fuel in the tank is stolen and is not real-time. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a truck fuel tank anti-theft device.

[0006] The technical solution of this utility model is as follows:

[0007] A truck fuel tank anti-theft device comprises: a skin and a controller, wherein the skin is sleeved around the fuel tank, and a monitoring optical fiber is arranged inside the skin; one end of the monitoring optical fiber is connected to a light source module through a transmission optical fiber, and the other end is connected to a photoelectric detection module through a transmission optical fiber; the controller is electrically connected to a power supply module, a photoelectric detection module, an alarm module, a light source module and a wireless signal transmission module respectively.

[0008] The skin is a three-layer structure, with optical fibers laid out in the two inner layers. The optical fibers in the bottom layer are distributed longitudinally at equal intervals, and the optical fibers in the upper layer are distributed transversely at equal intervals, so that distributed monitoring of the surface of the fuel tank can be performed.

[0009] The transmission optical fiber adopts a metal armored outer sheath to prevent the transmission optical fiber from being damaged.

[0010] The laser emitted by the light source module reaches the monitoring optical fiber in the skin through the transmission optical fiber, and then reaches the photoelectric detection module through the transmission optical fiber. When the optical fiber breaks, the alarm module activates the alarm, and the alarm signal is transmitted to the driver through the signal transmission module.

[0011] The monitoring optical fiber and the transmission optical fiber are both dual-core optical fibers.

[0012] The skin is made of fiber material and has the characteristics of wear resistance and hardness.

[0013] The skin is fixed to the surface of the fuel tank by a stainless steel tie, and can also be pasted to the surface of the fuel tank to prevent lawless elements from damaging the skin.

[0014] The controller adopts a shielding shell, which has the functions of preventing electromagnetic interference and waterproofing.

[0015] The power module is powered by 5-12V DC and is powered by a vehicle-mounted power supply.

[0016] The wireless signal transmission module can send the signal to the user in the form of a text message.

[0017] Technical effects and advantages of the utility model:

[0018] (1) The utility model overcomes the technical defects of the prior art. The structure is provided with a skin and a monitoring optical fiber.

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 The fuel tank anti-theft device for a truck shown in the figure comprises: a skin 1 and a controller 5, wherein the skin 1 is sleeved around the fuel tank, and a monitoring optical fiber 2 is arranged inside the skin 1; one end of the monitoring optical fiber 2 is connected to a light source module 9 through a transmission optical fiber 4, and the other end is connected to a photoelectric detection module 7 through a transmission optical fiber 4; the controller 5 is electrically connected to a power supply module 6, a photoelectric detection module 7, an alarm module 8, a light source module 9 and a wireless signal transmission module 10 respectively.

[0023] Furthermore, the skin 1 is a three-layer structure, with optical fibers laid out in the two inner layers, the optical fibers in the bottom layer are distributed longitudinally at equal intervals, and the optical fibers in the upper layer are distributed transversely at equal intervals, so that distributed monitoring of the tank surface can be performed.

[0024] Furthermore, the transmission optical fiber 4 adopts a metal armored outer sheath to prevent the transmission optical fiber from being damaged.

[0025] Furthermore, the laser emitted by the light source module 9 passes through the transmission optical fiber 4 to reach the monitoring optical fiber 2 in the skin, and then passes through the transmission optical fiber 4 to reach the photoelectric detection module 7. When the optical fiber breaks, the alarm module activates the alarm, and the alarm signal is transmitted to the driver via the signal transmission module.

[0026] Furthermore, the monitoring optical fiber 2 and the transmission optical fiber 4 are both dual-core optical fibers.

[0027] Furthermore, the skin 1 is made of fiber material and has the characteristics of wear resistance and hardness.

[0028] Furthermore, the skin 1 is fixed to the surface of the fuel tank with a stainless steel tie, or can be pasted on the surface of the fuel tank to prevent lawless elements from damaging the skin.
