[0002] The long rail transport power car is used to supply the electrical equipment of the entire train and is the power control center of the train. The existing power cars have the following defects: 1) There is only one fuel tank, which is installed at the rear end of the bottom of the car body, resulting in an unstable center of gravity. In addition, due to the gradual increase in modern electrical appliances, power consumption has increased, resulting in shorter replenishment intervals, affecting vehicle use and operation; 2) The existing car body chassis fuel tank is installed by adding bolts at three locations in the front, middle and rear. However, since the fuel tank is fixed at three locations in the front, middle and rear, it is easy to cause internal stress after the fuel tank is installed. The uneven stress accumulated over time causes cracks in the tank body, especially at the welds, and spreads, posing a huge safety hazard. Summary of the invention

[0003] The present invention aims to provide a new type of railway long steel rail transport double fuel tank generator car with a stable center of gravity that meets electricity demand and solves the problems of vehicle operation and operation affected by unstable center of gravity and insufficient power supply of a single fuel tank, and uneven stress in the installation of the fuel tank leading to the generation and spread of cracks in the tank body, especially at the welding points.

[0007] It is further preferred that a reinforced diagonal support beam is provided between the lower part of the fuel tank upper mounting seat located on the rear side and the main board to ensure the longitudinal strength of the fuel tank seat. If the diagonal support is cracked on site, it should be welded and repaired as soon as possible to ensure the structural stability of the fuel tank upper mounting seat. The design is reasonable, and reinforcing rib plates connected to the side walls of the box body are installed at intervals on the left and right sides of the top horizontal plane of the fuel tank lower mounting seat. The reinforcing rib plates connect the inverted "L"-shaped mounting plate and the side walls of the box body to enhance the structural stability.

[0008] Further preferably, the fuel tank capacity is 1500L, and the tank size is 2230mm long × 900mm wide × 550mm high. The size is reasonable and meets the power demand of the whole vehicle equipment. The distance between the center of the two fuel tanks and the longitudinal center line of the body chassis is consistent and is b, b is 900mm~1000mm, and the centers of the two fuel tanks are respectively located on the left and right sides of the transverse center line of the body chassis, and the longitudinal distance between the front end surfaces of the two fuel tanks is a, a is 2200mm~2300mm. The size design is reasonable, and the asymmetrical arrangement of the two fuel tanks effectively disperses the bottom center of gravity to ensure the balance of the center of gravity of the body chassis.

[0009] Further preferably, the short cross beam is connected to the long longitudinal beam, and the short cross beam is made of 180-type channel steel, which is reasonably selected to meet the strength requirements of the vehicle body chassis.

[0012] Further preferably, the oil gauge assembly includes an oil gauge seat, transparent glass embedded in the oil gauge seat and an oil gauge scale located outside the transparent glass, the oil level inside the fuel tank is exposed through the transparent glass, and the oil amount is calculated with the help of the oil gauge scale, and a rubber gasket is provided between the oil gauge seat and the transparent glass to ensure sealing, and the structural design is reasonable.

[0013] Further preferably, a support frame with a front-to-rear symmetrical structure is provided at the bottom of the box, which effectively avoids direct contact between the box and the ground before the box is installed, thereby reducing the possibility of the box being bumped, and the structural design is reasonable.

[0014] Beneficial effects of the present invention:

[0015] (1) Compared with the current single fuel tank with unstable center of gravity, insufficient power supply and uneven fuel tank installation stress, this solution adopts double fuel tanks to effectively meet the growing power demand of electrical equipment, and then cleverly uses the crossbeam of the vehicle body frame to install the fuel tank upper mounting seat. The fuel tank upper mounting seat is an "L"-shaped structure as a whole. The fuel tank upper mounting seat can be hooked up and down with the fuel tank lower mounting seat located at the front and rear ends of the fuel tank and fixed by bolts. The fuel tank is easy to install and stable, the structural design is linked together, the conception is novel, and the design is ingenious.

[0016] (2) The double fuel tanks are installed asymmetrically on the left and right sides, which effectively avoids gravity concentration and balances the weight of the vehicle body. The design is reasonable. The multifunctional hole on the left fuel tank is installed with a one-way pressure regulating valve, and the multifunctional hole on the right fuel tank is installed with an oil suction pipe extending into the vehicle compartment. The one-way pressure regulating valve can effectively balance the atmospheric pressure, especially in the hot summer when the oil in the tank evaporates and the internal pressure increases, which needs to be adjusted in time. At the same time, it can also filter moisture in the air to prevent moisture from entering the fuel tank. The oil suction pipe facilitates the extraction of oil from the fuel tank. The two fuel tanks are connected by a connecting hose to ensure that the oil is connected to each other, the oil level remains consistent, and the atmospheric pressure remains balanced inside and outside. The design structure is reasonable.

[0017] (3) The oil tank connecting seat is an inverted "L"-shaped elbow structure as a whole, and the port located on the box body is arranged downward, which effectively prevents the oil tank from vibrating when the oil in the two tanks flows to each other. Excessive vibration for too long may even affect the structural stability of the mounting seat on the oil tank, causing the risk of cracking of the oil tank and the mounting seat on the oil tank. In addition, the port located on the box body is arranged downward, which can also adjust the oil volume when the oil tank is in a low position, thereby increasing the range of oil volume balance adjustment. The design is ingenious. Ball valves are provided at both ends of the connecting hose to connect with the outer end of the oil tank connecting seat to realize manual control of the switch, flexible operation, and reasonable design.

[0018] In summary, the present invention has the advantages of convenient and stable fuel tank installation, asymmetrical installation of double fuel tanks on the left and right, balanced vehicle weight, balanced internal and external atmospheric pressure of the fuel tanks, and an interlocking structural design.
