Description

Technical Field

[0001] The utility model belongs to the technical field of oil tank oil quantity detection, in particular to an oil tank oil quantity detection device. Background Art

[0002] Large vehicles are the basis of logistics and transportation, and fuel is the blood of vehicles. In recent years, the continuous rise in oil prices has brought a series of adverse reactions to the domestic refined oil market. Many private gas stations see the profits and often operate secretly, by changing the pulse of the gas pump to reduce the oil output to achieve the purpose of stealing oil, which brings considerable economic losses to the majority of drivers and increases logistics costs. In this case, the contradictions between drivers and private gas stations continue to increase. The reason is that the vehicle itself has no accurate oil detection device. Before refueling, the driver cannot clearly know the amount of remaining oil in his tank and the amount of new oil added. The gas station has always unilaterally used the value displayed on the gas pump as the standard, which is unfair. The driver knows that he is short-changed, but because he can't find evidence, he can do nothing about this behavior.

[0003] A Chinese patent with application number 202121856189.6 discloses a fuel level detection device for a truck mounted on the side of a fuel tank, comprising a fuel storage pipe vertically installed on the side of the fuel tank through an installation assembly, the fuel pipe being made of a transparent material and having scale lines printed on the outer surface along the longitudinal direction, a marking ring being longitudinally movably sleeved on the outside of the fuel pipe, a vent pipe and an oil pipe being respectively provided on the top and bottom of the fuel storage pipe, the vent pipe being connected to the top of the inner cavity of the fuel tank, and the oil pipe being connected to the bottom of the inner cavity of the fuel tank so that the fuel storage pipe and the fuel tank form a communicating vessel. The fuel level detection device for a truck mounted on the side of the fuel tank makes it convenient for truck drivers to intuitively observe the remaining oil in the tank, how much new oil has been added, and how much oil there is in total from the oil level detection device installed on the fuel tank when refueling. The device is quick to install, easy to use, simple in structure, and highly reliable.

[0004] However, the above-mentioned fuel tank side-mounted truck fuel level detection device has the following shortcomings: due to the entry of fuel into the fuel storage pipe, a certain amount of fuel will still adhere to the inner wall even after reflux, which will affect the transparency of the observation window position over a long period of time, making it inconvenient to observe the liquid level.

[0005] Therefore, in view of the above problem, a fuel tank oil level detection device is proposed. Utility Model Content

An insertion rod 63 is connected to the top of the displacement block 61. The top of the insertion rod 63 penetrates the fuel storage pipe 2 and is fixedly connected to a top plate 64 with the protective shell 1. A driving motor 65 is installed on the top of the top plate 64. A screw rod 66 is connected to the output end of the driving motor 65. The screw rod 66 is threadedly connected to a threaded sleeve 67. The threaded sleeve 67 is fixed on the protective shell 1. When the fuel in the fuel tank reaches the bottom, the scraper ring 62 can be used to scrape the inner wall of the fuel storage pipe 2 when the displacement block 61 moves downward, so as to avoid the transparent window 4 being blurred due to the long-term adhesion of fuel, which is conducive to the observation of the internal oil amount.

[0030] Specifically, a connecting rod 7 symmetrically arranged up and down is fixedly connected to a side of the protective shell 1 away from the liquid level window 5 , and the connecting rod 7 is fixedly connected to a fixing plate 8 , and fixing holes 9 are provided at four corners of the fixing plate 8 .

[0031] Furthermore, one end of the connecting pipe 3 away from the fuel storage pipe 2 is connected to a joint 10, and the joint 10 is connected to a position near the bottom of one side of the fuel tank.

[0032] Furthermore, a filler 11 is filled between the protective shell 1 and the fuel storage pipe 2, and a partition 12 is provided between the protective shell 1 and the fuel storage pipe 2. The position of the partition 12 corresponds to the transparent window 4 and the liquid level window 5. The protective shell 1 and the filler 11 form a double-layer protection to prevent the fuel storage pipe 2 from being damaged by external force and improve the protection effect.

[0033] It is worth noting that a floating block 13 is provided inside the fuel storage pipe 2 , a through hole 14 is provided outside the floating block 13 , and a fluorescent strip 15 is provided on the outer surface of the floating block 13 .

[0034] It is worth noting that a bottom air port 16 is installed at the bottom of the displacement block 61 , and the bottom air port 16 is connected to an air flow channel 17 , and the air flow channel 17 is arranged in the extension rod 63 , and the top of the air flow channel 17 is connected to a top air port 18 , and the top air port 18 is arranged on the top plate 64 .

[0037] Working principle and process: The connector 10 at the end of the connecting pipe 3 is connected to the fuel tank, and the connection position should be near the bottom of the fuel tank. The device is fixed to the fuel tank through the fixing plate 8. After the connecting pipe 3 is connected to the fuel tank, the fuel in the fuel tank enters the fuel storage pipe 2 through the connecting pipe 3, and the air inside the fuel storage pipe 2 is discharged from the top air port 18 after passing through the bottom air port 16 and the air flow channel 17, so that the fuel can enter the fuel storage pipe 2. At this time, the liquid level in the fuel storage pipe 2 is consistent with the liquid level of the fuel in the fuel tank, and the fuel in the fuel tank can be observed. The floating block 13 in the fuel storage pipe 2 is attached to the liquid surface, which makes it easier to observe the liquid level. When the oil level in the fuel tank reaches the bottom, the fuel inside the fuel storage pipe 2 will also reach the bottom. At this time, the drive motor 65 is started, and then the screw 66 rotates. Under the action of the threaded sleeve 67, the top plate 64 moves downward, so that the insertion rod 63 drives the displacement block 61 to move downward, and the cleaning ring 62 on the outside of the displacement block 61 cleans the inner wall of the fuel storage pipe 2, so that the position of the transparent window 4 will not be blurred by the attached fuel, so as to facilitate the observation of the oil level through the liquid level window 5 and the transparent window 4.
