Technical Field

[0001] This utility model relates to a fuel tank structure and engineering equipment, belonging to the technical field of fuel tank design and structure. Background Technology

[0002] Many fuel-powered construction machinery and vehicles operate on slopes (especially steep inclines). Fuel tanks are often not perfectly round; they contain concave angles. When operating in extreme conditions such as transverse, longitudinal, or combined transverse and longitudinal slopes, the fuel level within these concave angles can vary. Currently, many machines use a single fuel inlet, which is positioned only at the lowest point of the fuel level under normal conditions. This can lead to situations where the fuel is drawn away completely under different circumstances, resulting in insufficient vehicle power, sluggish movement, or engine stalling. This not only affects work efficiency but can also seriously endanger the safety of personnel and equipment.

[0003] Therefore, existing fuel tank structures lack support for the function of drawing fuel from the tank under extreme conditions. Utility Model Content

[0027] The technical solutions of this application / the embodiments thereof will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application / the embodiments thereof, and not all embodiments thereof. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application / the application thereof or its application or use. Example 1

[0028] This embodiment provides a fuel tank structure to solve the problem in the prior art that "existing fuel tank structures lack support for the function of drawing fuel from the fuel tank under extreme attitudes".

[0029] The oil tank structure provided in this embodiment includes an oil tank body 1; it also includes a plurality of first oil suction pipes 2, each of which is connected to the oil tank body 1, and the connection point is located at the lowest liquid level point of the oil tank body 1 under different extreme postures.

[0030] The fuel tank structure provided in this embodiment has connection points of the first oil suction pipe 2 arranged at the lowest liquid level under different extreme postures. Different first oil suction pipes 2 can be selected to suck oil from the corners where there is still fuel in the fuel tank body 1, which can prevent the fuel from being sucked out. At the same time, it provides a platform for those skilled in the art to realize the function of sucking oil from the fuel tank body 1 under extreme postures. Example 2

[0031] This embodiment provides a fuel tank structure to solve the problem in the prior art that "existing fuel tank structures lack support for the function of drawing fuel from the fuel tank under extreme attitudes".

[0032] refer to Figure 1 and Figure 2 The fuel tank structure provided in this embodiment includes,

[0033] Fuel tank body 1;

[0034] Multiple first oil suction pipes 2 are connected to the oil tank body 1, and the connection point of each first oil suction pipe 2 is located at the lowest liquid level point under different extreme postures of the oil tank body 1.

[0035] Liquid level sensor 7 is used to sense the liquid level in the oil tank body 1 and send liquid level sensing signals;

[0036] Each first oil suction pipe 2 is equipped with a switch control valve 3. The switch control valve 3 can receive control signals and can also control the opening and closing of the corresponding first oil suction pipe 2.

[0037] Figure 1 The oil tank body 1 shown is a typical irregular, non-standard oil tank with concave angles. Under steep inclination angles, conventional oil suction ports cannot draw oil. However, in the oil tank structure provided in this embodiment, the connection points (equivalent to oil suction ports) of the first oil suction pipe 2 are arranged at the lowest liquid level points under different extreme postures. The on / off point of the first oil suction pipe 2 is controlled by the switch control valve 3, and it also includes a liquid level sensor 7 for sending liquid level sensing signals inside the oil tank body 1. This provides a platform for those skilled in the art to realize the function of drawing oil from the oil tank under extreme postures.

[0038] The liquid level sensor 7 senses the liquid level in the fuel tank body 1 in the following ways, including but not limited to, sending a liquid level sensing signal after the fuel level has submerged a portion of the liquid level sensor 7.

[0039] For example, those skilled in the art will readily recognize that, based on the platform functionality provided by the tank structure in this embodiment, by implementing a scheme that "responds to the liquid level sensing signals sent by some liquid level sensors 7, only controls the on / off control valve 3 of the first oil suction pipe 2 corresponding to the liquid level sensor 7 that sent the liquid level sensing signal to be connected, while keeping the on / off control valve 3 corresponding to the other liquid level sensors 7 that did not send the liquid level sensing signal disconnected," it is possible to directly achieve the effect of only drawing oil from the first oil suction pipe 2 at the oil-containing position under extreme conditions, while not drawing oil from other positions, thus preventing cavitation. This process can be referred to... Figure 2 .

[0040] Those skilled in the art will readily recognize that other methods can be implemented based on the platform functionality support of the fuel tank structure provided in this embodiment to achieve other deeper functions. Example 3

[0041] This embodiment provides a fuel tank structure. This embodiment is an optimization based on Embodiment 2 to improve the technical effect and refine the technical solution. For details not described in this embodiment, please refer to Embodiment 1.

A probe head 7.3 is also provided at the end of the fixing rod 7.2 away from the anti-detachment component 7.1.

[0043] The anti-detachment component 7.1 (or mounting base) is placed on the outer surface of the fuel tank body 1 to prevent it from falling into the interior of the fuel tank body 1. In addition, the probe head 7.3 can be arranged in the most suitable position by means of the fixing rod 7.2. This allows the anti-detachment component 7.1 to be installed in the most reliable position on the outer surface of the fuel tank body 1, and the probe head 7.3 to be arranged in the most suitable position by means of the fixing rod 7.2, thus meeting the positional requirements of the two components.

[0046] As one embodiment, the liquid level sensor 7 is a capacitive liquid level sensor that can measure the liquid level of non-conductive liquids.

[0047] In one embodiment, the switch control valve 3 is a hydraulic switch valve, a pneumatic switch valve, an electric switch valve, or a switch valve controlled by a mechanical mechanism. When it is a switch valve controlled by mechanical principles, it can be manually controlled; when it is controlled by signal principles, it is mainly subject to automated control.

[0048] In one embodiment, the oil tank structure also includes a confluence block 5, a second oil suction pipe 4, and a third oil suction pipe 6; the second oil suction pipe 4 and the corresponding first oil suction pipe 2 are connected by a switch control valve 3, which is used to control the flow direction from the first oil suction pipe 2 to the second oil suction pipe 4. Multiple second oil suction pipes 4 are connected to the oil inlet of the confluence block 5, and the oil outlet of the confluence block 5 is connected to the third oil suction pipe 6.

[0049] The second oil suction pipe 4 is a functional extension of the first oil suction pipe 2. Under different extreme postures, some second oil suction pipes 4 can suck up oil while others cannot. The confluence block 5 is used to merge different second oil suction pipes 4 and concentrate the fuel in the second oil suction pipes 4 containing oil to supply the third oil suction pipe 6, which then supplies the oil-using components.

[0050] As one embodiment, reference Figure 2 The tank structure also includes a controller 8 connected to the signal terminal of the level sensor 7, and a switch control valve 3 for issuing control signals. The controller 8 is also connected to the switch control valve 3. Those skilled in the art can deploy control algorithms on the controller 8 to achieve deeper functionality.
