Oil tank capable of being infinitely cascaded

Abstract

The invention discloses an oil tank capable of being infinitely cascaded. The oil tank comprises an oil tank body, an oil pump assembly and a control panel. The lower end of the oil pump assembly extends into the oil tank body, an oil inlet nozzle, an oil outlet nozzle and an oil pump main control plug assembly are arranged at the upper end of the oil pump assembly, the oil pump main control plugassembly is connected with a control panel, and the control panel controls oil outlet or oil inlet of the oil pump assembly. According to the oil tank, another auxiliary oil tank can be connected to the next stage of the auxiliary oil tank, a secondary auxiliary oil tank can supply oil to the auxiliary oil tank of the stage, and the oil tanks are sequentially connected and cascaded.

Description

technical field [0001] The invention relates to a fuel tank which can be cascaded infinitely. Background technique [0002] As the demand for cruising range of automobiles increases, the fuel storage requirements of vehicles are also increasing. However, a single fuel tank is limited by the space layout, and it is impossible to expand its fuel storage indefinitely, resulting in a small storage capacity of the fuel tank. Frequent refueling is required during use. When encountering areas with low density of gas stations such as Xinjiang or Tibet, it is often difficult to refuel. Therefore, the application of multi-tank structures is of great significance. [0003] At present, there are two main oil supply methods for the multi-tank structure: 1. Independent fuel supply for the left and right fuel tanks; 2. A saddle-shaped fuel tank that uses the principle of a connector to keep the oil levels of the main and auxiliary fuel tanks consistent, and the main fuel tank is responsibl...

AI Technical Summary

Problems solved by technology

There are too many connecting pipelines between the left fuel tank and the right fuel tank, and two three-way valves need to be operated when switching, which is error-prone and cumbersome, and it is difficult to supply fuel to the third fuel tank after the two fuel tanks are used up

For the saddle-shaped fuel tank in the prior art, it is gradually popularized due to its simple molding and less required fuel quantity sensors. Mainly research on the main and auxiliary fuel tanks and their connection methods, there are still few reports on the connection methods of the third fuel tank or the fourth fuel tank, and there will also be insufficient fuel supply
