[0027] Before introducing the technical solution of the utility model, it is necessary to explain the creation background of the utility model. It is common that the oil tank of the existing railway mechanical refrigerated car is welded by two side plates, two end plates, a bottom plate and a top plate. A fuel sedimentation tank and a drain port for cleaning the oil tank are welded on the bottom plate of the oil tank, and a refueling port is welded on the end plate. A mechanical oil level gauge is provided at each end of the oil tank to read the fuel amount. However, the oil tank adopting the above structure has too many welds and there is a risk of fuel leakage, which has very high requirements for manufacturing quality and reliability; in addition, the oil tank is only provided with a mechanical oil level gauge, which cannot meet the unmanned function requirements of the vehicle. To this end, the utility model aims to provide a fuel supply device for a railway mechanical refrigerated car.

[0028] Based on the above problems, the exemplary embodiment of the present utility model is shown in FIG. Figures 1 to 3 , a fuel supply device for a railway mechanical refrigerated vehicle is provided, comprising a fuel tank body, the fuel tank body comprising a U-shaped plate 1, a top plate 2 and two side plates 3. The bottom of the U-shaped plate 1 is arranged on a mounting support 4, the top plate 2 is provided with at least one cleaning window 21, and the top plate 2 is provided with an electronic oil level gauge 26 and a mechanical oil level gauge 23 which are connected to the inside of the fuel supply device, wherein the U-shaped plate 1 is an integrated structure; the U-shaped plate 1, the top plate 2 and the two side plates 3 are connected and fixed by welding. It should be noted that the mounting support 4 is fixed on the floor of the carriage, and is used to realize the installation and fixation of the above-mentioned fuel supply device.

[0029] The fuel supply device for railway mechanical refrigerated vehicles adopting the above structure has the following advantages: 1. The fuel tank body is composed of a U-shaped plate, a top plate and two side plates instead of the traditional eight side plates to reduce welds and effectively reduce the occurrence of oil leakage; 2. The cleaning window of the fuel tank is set on the top plate, which is convenient for operators to clean the inside of the fuel tank and remove impurities; 3. The fuel supply device is equipped with an electronic oil level gauge and a mechanical oil level gauge. The operator can not only read the usage of the fuel in the car, but also obtain the fuel in real time through the remote monitoring system, meeting the technical requirements of unmanned vehicles. Therefore, compared with the existing fuel tank technology, the fuel supply device for railway mechanical refrigerated vehicles provided by the utility model has obvious technical advantages.

[0030] In some embodiments, the electronic oil level gauge 26 is connected to the gasoline gauge to indicate the amount of fuel in the fuel supply device. The electronic oil level gauge 26 specifically converts the oil level signal of the fuel storage amount into a current signal through a circuit, so that the operator can remotely monitor the amount of fuel stored in the fuel supply device. In some embodiments, the mechanical oil level gauge 23 is a screw-type oil level gauge to reduce the failure rate caused by the excessive movement of the float in the traditional pendulum oil level gauge, thereby improving safety. Therefore, through the above-mentioned electronic oil level gauge 26 and the screw-type oil level gauge, remote monitoring and local detection of the fuel storage amount in the car can be achieved, so that the fuel in the fuel supply device can be replenished in time.

[0031] In some embodiments, see Figure 2 , the fuel tank body includes a plurality of partitions 5 inside. Specifically, the function of the partition 5 is to separate the oil return area from the oil suction area of ​​the oil pump, increase the path of fuel circulation, reduce the circulation speed of fuel, and facilitate cooling and heat dissipation, bubble precipitation and impurity precipitation. Preferably, the utility model includes a plurality of transverse partitions 5 and longitudinal partitions 5, and a plurality of partitions 5 are also provided with circulation windows 51 for the fuel to circulate smoothly inside the fuel supply device. Furthermore, each circulation window 51 can be equipped with a filter screen of a considerable area to further filter impurities from the fuel.

[0032] Preferably, see Figure 1 The top plate 2 includes an exhaust hole 22, and the exhaust hole 22 is used to maintain the internal air pressure balance of the fuel supply device so that the fuel can flow smoothly inside and outside the fuel supply device.

[0033] In some embodiments, see Figure 1 and Figure 2 The top plate 2 also includes an oil filling port 24 and an oil inlet and return port 25. The oil filling port 24 is used to input fuel into the fuel tank, and the oil inlet and return port 25 is used to deliver fuel to the generator set. The oil inlet and return port 25 is a connecting link between the fuel supply device and the generator set. Specifically, the oil inlet and return port 25 includes an oil inlet connected to an oil inlet pipe and an oil return port connected to an oil return pipe. In order to avoid mutual influence between the oil filling port 24, the oil inlet and the oil return port during operation, when setting the positions of the three, it is necessary to leave enough working clearance between the three to avoid contact.

[0034] Further, in some embodiments, see Figure 1 and Figure 2 A first mounting bracket 11 is provided on the side of the fuel supply device. The first mounting bracket 11 is used to install an electronic oil pump (not shown in the figure). The electronic oil pump is used to extract and pressurize the fuel from the inside of the fuel supply device, and then transport the fuel to the generator set through the oil inlet and return port 25.

[0035] In some embodiments, see Figure 1 and Figure 2 The side of the fuel supply device is also provided with a second mounting frame 12, and the second mounting frame 12 is used to install an oil-water separator (not shown in the figure). The oil-water separator is used to remove water from the fuel to reduce the failure of the fuel injector. The oil-water separator is a type of fuel filter, and its main function is to remove water from the fuel, reduce the failure of the fuel injector, and extend the service life of the generator set. The principle is mainly based on the density difference between water and fuel, and the separator uses the principle of gravity sedimentation to remove impurities and water. There are also separation elements such as diffusion cones and filters inside. The oil-water separator also has other functions, such as preheating the fuel to prevent waxing, filtering impurities, etc.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
