AI Technical Summary
In the cold winter, when diesel locomotives use 0# diesel, the low temperature causes poor fluidity and easy wax precipitation, which makes the diesel engine unable to extract diesel. The locomotive's cooling water system is also prone to freezing damage, increasing operating costs. Furthermore, long-term use of -35# diesel increases cost consumption.
A temperature detection device is used to monitor the fuel temperature in real time, and a temperature control device heats the fuel in the fuel tank to a constant temperature range. An airbag control device adjusts the telescopic sleeve according to changes in the fuel level in the tank to ensure that the fuel temperature is within a suitable range.
This effectively reduces the fuel consumption cost of locomotives in winter, ensures the safe and stable operation of locomotives, and avoids the need to replace high-cost diesel fuel.

Description
Technical Field
[0001] This utility model relates to the field of fuel temperature detection technology for internal combustion locomotives, and in particular to a fuel tank heating temperature detection and control device for internal combustion locomotives. Background Technology
[0002] In northern and cold-winter regions, diesel locomotives require timely replacement with -35# diesel fuel as the outside temperature drops. Otherwise, the normally used 0# diesel fuel will become sluggish and waxy due to the low temperature, causing the diesel engine to stop due to insufficient fuel extraction. The locomotive's cooling water system is also susceptible to freezing damage, potentially impacting winter transportation and production. Using -35# diesel fuel for up to five months in winter increases the cost per locomotive, leading to higher overall operating costs and contradicting the company's current energy-saving and consumption-reducing management requirements. Therefore, inventing a safe, practical, and temperature-controlled fuel tank temperature control device is essential. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a fuel tank heating temperature detection and control device for diesel locomotives. This invention primarily utilizes a temperature detection device to monitor the fuel temperature inside the fuel tank in real time and transmit this data to the driver's cab. A temperature control device then maintains the fuel in the tank within a constant temperature range based on the detected temperature. This device effectively heats the fuel in the tank and controls the temperature based on the detected fuel temperature, ensuring that the temperature is kept within the required range during cold winter seasons, reducing fuel consumption costs for the locomotive in winter, and ensuring the safe and stable operation of the locomotive.

[0048] Example
[0049] like Figure 1 As shown, this utility model provides a fuel tank heating temperature detection and control device for internal combustion locomotives. It is mainly used for fuel tank heating, temperature detection, and automatic constant temperature control in locomotives, thereby providing 0# diesel fuel to the diesel engine during the cold winter season and reducing costs. The implementation method is as follows:
[0050] The fuel tank is equipped with an insulation layer to prevent the water pipes inside from freezing. The fuel tank also features partitions dividing it into three sections to prevent fuel level fluctuations during locomotive operation, which could affect the smooth running of the locomotive.
[0051] In winter, the water pipe valve is opened to introduce the high-temperature water from the diesel engine into the water inlet pipe of this utility model.
[0052] High-temperature water enters the first section of the fuel tank pipeline and heat dissipation device. The anti-corrosion telescopic pipe changes the length of the heating pipe according to the fuel level in the tank to improve heat transfer efficiency. Finally, it enters the diesel engine water circulation system through the water outlet pipe.
[0053] After the temperature sensor placed in the insulation layer at the bottom of the fuel tank detects the oil temperature, it is transmitted to the display screen on the co-driver's console in the driver's cab through the signal processing unit, so as to achieve visual observation.
[0054] If the winter temperature continues to drop and becomes extremely cold, the pipeline to the third zone will be opened depending on the outside temperature and the fuel temperature, and the heater in the third zone will start working.
[0055] 5.0# diesel fuel will solidify below 0℃, affecting its fluidity. Based on years of experience, it can be used normally within a temperature range of 4℃-10℃. The temperature control device activates the heater when the fuel tank temperature is below 4℃ and deactivates it when the temperature exceeds 10℃.
[0056] This diesel locomotive fuel tank heating temperature detection and control device features a scientific and reasonable layout, convenient and safe operation, and reasonable use of waste heat from the locomotive's diesel engine. In winter, it can effectively maintain the temperature of 0# diesel fuel in the fuel tank within a suitable range, eliminating the need to replace it with -35# diesel fuel, reducing locomotive operating costs, and achieving the goal of energy conservation and consumption reduction.
