Description

Technical Field

[0001] This utility model belongs to the technical field of fuel system for engineering machinery, and specifically relates to a fuel tank device that prevents splashing and overflow. Background Technology

[0002] In construction machinery such as underground loaders, fuel tanks are typically designed with a filter-type refueling device that has a breathing function and usually uses a straight-tube refueling port. However, in the complex working environment of construction machinery, such as long-term uphill operations or transportation operations on bumpy roads, existing fuel tanks lack anti-overflow and flow guidance structures. During long-term uphill or bumpy road operations, fuel may overflow or splash from the fuel tank's refueling port, causing fuel waste, environmental pollution, and safety issues.

[0003] Patent CN 205315175U discloses a detachable overflow-proof refueling port for a fuel generator set, including a base and a generator, engine, and fuel tank mounted on the base. A movable connector connects the refueling pipe to the fuel tank. Several overflow-proof baffles are provided on the inner wall of the refueling pipe, and the baffles are non-enclosed to the inner wall of the refueling pipe. Even with severe shaking of the fuel generator, fuel is unlikely to overflow from the refueling port. However, adding overflow-proof baffles to the inner wall of the refueling pipe affects the smoothness of refueling and is cumbersome to manufacture due to limited operating space. Therefore, there is a need to develop a fuel tank that is simple to manufacture and effectively prevents fuel splashing and overflow during vehicle operation on bumpy roads and long-distance uphill / downhill terrain.

[0006] Furthermore, when the baffle rotates backward to the first limiting plate, the lower end of the baffle comes into close contact with the buffer plate.

[0007] Furthermore, a counterweight is provided at the lower part of the front end face of the baffle.

[0008] Furthermore, there are two counterweights, which are located on the left and right sides of the baffle, and the second limiting plate is positioned corresponding to the two counterweights.

[0009] Furthermore, the buffer plate is an inclined structure, with the buffer plate gradually tilting downwards from back to front and from right to left.

[0010] Furthermore, one end of the guide bend is connected to the filler port, and the other end is bent backward.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Reference Figure 1-5 A fuel tank device for preventing splashing and spillage includes a tank body 1, a filler neck 2, a guide bend 3, a buffer plate 4, a baffle 5, a first limiting plate 6, and a second limiting plate 7. The filler neck 2 is located at the upper rear of the tank body 1. The guide bend 3 is located inside the tank body 1 and is connected to the filler neck 2. The buffer plate 4 is located below the guide bend 3, and the rear end of the buffer plate 4 is fixed to the inner wall of the tank body 1. The baffle 5 is located on the front side of the guide bend 3, and the upper end of the baffle 5 is rotatably connected to the inner wall of the tank body 1. The first limiting plate 6 is fixed to the upper end of the buffer plate 4, and the second limiting plate 7 is located at the lower part of the baffle 5 and is fixed to the inner wall of the tank body 1.

[0026] The design of the guide bend 3 does not affect the smoothness of refueling at the filler neck 2, and also buffers the fuel in the fuel tank, preventing fuel from directly impacting the filler neck 2. The buffer plate 4 is mainly designed to address the situation where fuel splashes into the filler neck 2 on bumpy roads. By reducing the amount of fuel accumulation below the guide bend 3, the buffer plate 4 reduces fuel splashing caused by vehicle shaking.

[0027] Furthermore, when the baffle 5 rotates backward to the first limiting plate 6, the lower end of the baffle 5 is in close contact with the buffer plate 4. When the baffle 5 rotates to the first limiting plate 6, the baffle 5, the buffer plate 4, and the inner wall of the housing 1 form a sealed area, preventing fuel from entering this sealed area and thus preventing it from overflowing from the guide bend 3 and the filler port 2.

[0028] Furthermore, a counterweight 8 is provided at the lower part of the front end face of the baffle 5. The counterweight 8 allows the baffle 5 to rotate under the gravity of the counterweight 8 when the vehicle is moving, especially when going downhill or uphill.

[0029] Furthermore, there are two counterweights 8, which are located on the left and right sides of the baffle 5, and the second limiting plate 7 is positioned corresponding to the two counterweights 8.

[0030] Furthermore, the buffer plate 4 is an inclined structure, gradually tilting downwards from back to front and from right to left. This inclined arrangement reduces fuel accumulation at this location, thereby reducing fuel splashing caused by vehicle shaking.

[0031] Furthermore, one end of the guide bend 3 is connected to the filler neck 2, and the other end is bent backward. The bending direction of the guide bend 3 is coordinated with the buffer plate 4, which effectively reduces fuel splashing when the vehicle shakes, and prevents fuel from rising to the filler neck 2 when the vehicle is going downhill.

[0032] Furthermore, there are two first limiting plates 6, which are respectively located on the left and right sides of the buffer plate 4. The two limiting plates limit the baffle 5, so that the baffle 5 is subjected to uniform force and has a stable structure.

[0033] Furthermore, the baffle 5 is connected to the inner wall of the housing 1 via a hinge. The baffle 5 is fixed to the inner wall of the housing 1 by the hinge, allowing the baffle 5 to rotate back and forth.

[0034] Furthermore, the second limiting plate 7 is located on the front side of the baffle 5, and the buffer plate 4 is located on the rear side of the baffle 5. When the vehicle goes uphill, the baffle 5 rotates backward to contact the first limiting plate 6. The baffle 5, the buffer plate 4, and the inner wall of the tank 1 form a sealed space, and the fuel in the tank 1 cannot enter this space, so it cannot overflow and splash from the guide bend 3 and the filler port 2.

[0035] When the fuel tank device of this utility model is in operation, when the vehicle is driving on a bumpy road, the guide bend 3 buffers the fuel in the fuel tank, preventing the fuel from directly impacting the filler neck 2 and thus preventing fuel splashing. When the vehicle is driving downhill, the front of the fuel tank tilts downward. At this time, the baffle 5 contacts the second limiting plate 7 under the action of the counterweight 8. Since the filler neck 2 is located at the rear of the tank body 1, the fuel will not rise to the filler neck 2 position, and fuel splashing will not occur. When the vehicle is driving uphill, the rear of the fuel tank tilts downward. At this time, the baffle 5 contacts the first limiting plate 6 under the action of the counterweight 8. The baffle 5, the buffer plate 4, and the inner wall of the tank body 1 form a sealed space. The fuel does not enter this sealed space, and the fuel will not rise to the filler neck 2 position, thus preventing fuel splashing.
