Description
Technical Field
[0001] This utility model relates to the field of fuel tanks, specifically to a fuel tank device that prevents air suction and facilitates easy cleaning. Background Technology
[0002] Construction machinery needs to be able to handle various complex working conditions. When the equipment is in complex conditions such as mountains and mines, it is often in a state of going uphill, downhill, bumping, and tilting left and right. Under these working conditions, the fuel in the fuel tank will tilt along with the vehicle, causing the fuel suction pipe to run dry and unable to draw fuel, which will cause the engine to stall and other phenomena, posing a serious danger to people and vehicles.
[0003] To address the aforementioned issues, the existing solution involves placing the fuel suction pipe centrally. Positioning the fuel suction pipe at the bottom center of the fuel tank mitigates the risk of cavitation due to unidirectional tilting during inclines, declines, and lateral bumps. However, this solution still cannot completely prevent cavitation when the fuel level is low, the slope is steep, or operating conditions are harsh.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention
[0005] To improve or solve the technical problem of air suction in the fuel suction pipe when the fuel level is low or the slope is steep and the operating conditions are poor, this utility model provides a fuel tank device that prevents air suction and facilitates easy cleaning. The fuel tank device includes: a fuel tank body with a fuel suction pipe installed on it; a fuel storage box installed below the fuel tank body and having a storage cavity communicating with the interior of the fuel tank body; the fuel storage box is arranged directly below the fuel suction pipe, with one end of the fuel suction pipe extending into the storage cavity; and a fuel storage enclosure plate installed inside the fuel tank body, forming an open fuel storage trough around the fuel storage box; the fuel storage trough is configured to trap fuel when the fuel tank body is tilted.
[0006] This invention relates to a fuel tank device for preventing cavitation and facilitating easy cleaning, comprising a fuel tank body, a fuel storage box, and a fuel storage baffle. The fuel tank body holds fuel. A fuel suction pipe is installed on the fuel tank body to draw fuel from the tank. The fuel storage box is located directly below the fuel suction pipe, forming a storage chamber. When the fuel level is low, the fuel concentrates in the storage chamber, ensuring effective fuel suction. When the fuel tank tilts, the storage chamber traps fuel, and one end of the fuel suction pipe extends into the storage chamber, further enhancing the cavitation prevention effect. The fuel storage baffle forms an open storage trough, which traps a large amount of fuel when the fuel tank tilts, ensuring the storage chamber is filled with fuel and preventing the fuel suction pipe from cavitating. Through these features, this invention provides a fuel tank device for preventing cavitation and facilitating easy cleaning, allowing for better fuel storage under complex conditions such as uphill or bumpy driving, and preventing the fuel suction pipe from cavitating.
[0007] Furthermore, the oil reservoir includes a first flange installed below the fuel tank and a second flange detachably connected to the first flange; an oil drain hole is provided on the second flange, and a plug is installed at the oil drain hole.
[0008] Furthermore, a magnet is installed on the second flange.
[0009] Furthermore, the fuel tank has a front end and a rear end, the fuel reservoir is positioned close to the front end, and the opening of the fuel reservoir faces the front end.
[0010] Furthermore, the oil storage enclosure includes a first baffle and a second baffle arranged side by side, and a third baffle connecting the first baffle and the second baffle; the first baffle and the second baffle are arranged at a distance from the front end.
[0011] Furthermore, the first baffle and the second baffle are connected to the rear end, and a connecting hole is provided on the first baffle and the second baffle.
[0012] Furthermore, the first baffle and the second baffle are arranged at a distance from the rear end.
[0013] Furthermore, the oil storage enclosure includes a first enclosure and a second enclosure arranged side by side, and a third enclosure connecting the first enclosure and the second enclosure; the two ends of the third enclosure are respectively connected to the ends of the first enclosure and the second enclosure near the rear end.
[0014] Furthermore, a level gauge is also installed inside the fuel tank.
[0015] Furthermore, an inlet pipe and a mounting bracket are also installed on the fuel tank.
[0016] In summary, compared with the prior art, this utility model has the following beneficial effects: (1) The oil storage plate forms an open oil storage tank, which can intercept a large amount of fuel when the fuel tank is tilted, so that the oil storage chamber can be filled with fuel and prevent the oil suction pipe from sucking up the empty; (2) A magnet is installed in the oil storage chamber, which can store and adsorb some metal particles and impurities.

Figure 1 As shown, this utility model discloses a fuel tank device for preventing air suction and facilitating easy cleaning, comprising a fuel tank body 1, a fuel collection box 2, and a fuel collection baffle 3. The fuel collection box 2 and the fuel collection baffle 3 are installed on the fuel tank body 1.
[0024] See also Figure 1 In one or more embodiments, the fuel tank 1 is generally rectangular parallelepiped in shape. The fuel tank 1 has opposing front and rear ends. Based on... Figure 1 The orientation shown indicates that the front end faces outwards from the paper and the rear end faces inwards from the paper. Specifically, the fuel tank 1 includes a front wall, a rear wall 11 opposite to the front wall, a left wall 12, a right wall 13 opposite to the left wall 12, a bottom wall 14, and a top wall opposite to the bottom wall 14. The front wall, top wall, rear wall 11, and bottom wall 14 are connected by inclined plates. Furthermore, a fuel inlet pipe 15 is installed on the top wall, through which fuel is delivered to the fuel tank 1. Furthermore, mounting brackets 16 are installed on the left wall 12 and right wall 13 to secure the fuel tank 1. Furthermore, a level gauge 17 is installed inside the fuel tank 1, positioned near the front wall and the left wall 12, to monitor the correct remaining fuel level. Furthermore, a fuel suction pipe 18 is installed on the fuel tank 1, positioned near the front wall.

[0025] Figure 2 This is a schematic diagram of the internal structure of a fuel tank device for preventing air suction and facilitating easy cleaning, as per this utility model. Figure 1 and Figure 2As shown, the fuel reservoir 2 is installed below the bottom wall 14 of the fuel tank 1 and has a fuel storage chamber communicating with the interior of the fuel tank 1. The fuel reservoir 2 is located near the front end, allowing for convenient fuel intake during downhill driving. Specifically, the fuel reservoir 2 is located directly below the fuel tank 1, and one end of the fuel suction pipe 18 extends into the fuel storage chamber. When the fuel level is low, the fuel can concentrate in the fuel reservoir 2, better achieving an anti-cavitation effect. In one or more embodiments, the fuel reservoir 2 includes a first flange 21 installed below the fuel tank 1 and a second flange 22 detachably connected to the first flange 21. The first flange 21 serves as the peripheral wall of the fuel reservoir 2, and the second flange 22 serves as the bottom wall 14 of the fuel reservoir 2. Specifically, a through hole matching the inner wall of the first flange 21 is provided on the bottom wall 14 of the fuel tank 1, and the first flange 21 can be welded to the bottom wall 14 of the fuel tank 1.

Furthermore, a drain hole is provided in the middle of the second flange 22, and a plug 23 is installed at the drain hole. Additionally, a magnet 24 is installed on the second flange 22 to attract metal particles.
[0026] See also Figure 1 and Figure 2In one or more embodiments, the fuel reservoir 3 is installed inside the fuel tank 1 and forms an open fuel reservoir around the fuel reservoir 2. This is used to trap fuel when the fuel tank 1 is tilted and to enhance the structural strength of the fuel tank 1. Specifically, the opening faces the front end of the fuel tank 1. When the vehicle is going uphill, the fuel tank 1 tilts, and fuel flows to the rear end of the fuel tank 1. Some fuel is trapped in the fuel reservoir by the fuel reservoir 3, making the fuel reservoir full of fuel. When the engine is running, the fuel suction pipe 18 draws fuel from the fuel reservoir, achieving a better anti-cavitation effect. When the vehicle is going downhill, fuel flows to the front end of the fuel tank 1, and the fuel reservoir is biased towards the front end of the fuel tank 1, allowing the fuel suction pipe 18 to draw fuel more effectively for the engine. Furthermore, the fuel reservoir 3 includes a first baffle 31 and a second baffle 32 arranged side by side, and a third baffle 33 connecting the first baffle 31 and the second baffle 32. Specifically, the first baffle 31 and the second baffle 32 have the same structure. The front ends of the first baffle 31 and the second baffle 32 are spaced apart from the front wall, the rear ends are connected to the rear wall 11, the lower ends are connected to the bottom wall 14, and the upper ends are spaced apart from the top wall. The third baffle 33 is arranged behind the oil reservoir. For example, the height of the first baffle 31 and the second baffle 32 is half the height of the fuel tank 1. The first baffle 31, the second baffle 32, the third baffle 33 and the rear wall 11 form a first chamber, with the opening located at the front of the first chamber. The first baffle 31, the second baffle 32 and the third baffle 33 form a second chamber. A connecting hole 34 is provided on the first baffle 31 and the second baffle 32, which connects the second chamber to the interior of the fuel tank 1. When the vehicle is in an uphill condition, the fuel in the second chamber can flow out of the second chamber through the connecting hole 34.
