Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, specifically a diesel engine with a safe fuel supply structure. Background Technology

[0002] A diesel engine is an internal combustion engine that uses a piston to compress air to generate high temperature and pressure, causing the injected diesel fuel to self-ignite (without spark plug ignition), thereby driving the piston to do work and output mechanical energy. It uses diesel fuel and has the characteristics of high compression ratio, high thermal efficiency, and high low-speed torque.

[0003] When using diesel engines in winter, the low temperature can make them difficult to start. At this time, the fuel tank needs to be preheated by the staff, which is inconvenient. After starting, the temperature of the fuel tank will drop again due to the influence of the external environment. In low temperature environment, the atomization effect of diesel fuel will be poor, resulting in a decrease in the combustion efficiency of the diesel engine and an increase in black smoke emitted from the exhaust port, which will pollute the working environment of the staff. Utility Model Content

[0006] The fuel tank is located inside the housing, and an exhaust pipe is connected to one side of the diesel engine body;

[0007] A connecting pipe is connected to the surface of the exhaust pipe, the other end of the connecting pipe passes through the interior of the diesel engine body and extends to its rear, the connecting pipe is U-shaped and fits against the surface of the fuel tank;

[0008] A water tank is located at the bottom of the oil tank, and a heating plate is installed inside the water tank. An exhaust structure is installed at one end of the top of the water tank.

[0009] Preferably, the exhaust structure includes a vent pipe connected to the top of the water tank. A fixing ring is fixedly connected to the inner cavity of the vent pipe. Connecting rods are movably connected to both sides of the inner cavity of the fixing ring. A baffle is fixed to one end of each connecting rod. A spring is sleeved on the surface of the connecting rod, and the two ends of the spring are fixed to the fixing plate and the fixing ring, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When used in low-temperature winter environments, this invention heats the concentrated brine inside the water tank by turning on the heating plate. The resulting heat then heats the fuel tank, facilitating the starting of the diesel engine. Simultaneously, the heat generated by the diesel engine during operation is discharged through the exhaust pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, a diesel engine with a safe fuel supply structure includes a diesel engine body 1, and a housing 2 is provided on the top of the diesel engine body 1. A fuel tank 6 is provided inside the housing 2. An exhaust pipe 3 is connected to one side of the diesel engine body 1, and a connecting pipe 4 is connected to the surface of the exhaust pipe 3. The other end of the connecting pipe 4 passes through the interior of the diesel engine body 1 and extends to its rear. The connecting pipe 4 is U-shaped and fits against the surface of the fuel tank 6 to facilitate better heat conduction to the fuel tank 6. A water tank 8 is provided at the bottom of the fuel tank 6. The solution in the water tank 8 is a concentrated brine. The concentrated brine in the water tank 8 has good antifreeze properties and is not easy to freeze in winter. A heat-conducting plate 10 is fixedly connected to the top of the water tank 8, and the top of the heat-conducting plate 10 fits against the fuel tank 6. The heat-conducting plate 10 can better heat the fuel tank 6. A heating plate 11 is provided in the inner cavity of the water tank 8, and an exhaust structure 7 is provided at one end of the top of the water tank 8.

[0024] The exhaust structure 7 includes a vent pipe 75 connected to the top of the water tank 8. A fixing ring 76 is fixedly connected to the inner cavity of the vent pipe 75. Connecting rods 73 are movably connected to both sides of the inside of the fixing ring 76. A baffle 72 is fixed to one end of each connecting rod 73. A spring 74 is sleeved on the surface of the connecting rod 73, and both ends of the spring 74 are fixed to the fixing plate 71 and the fixing ring 76, respectively. The inner diameter of the fixing ring 76 is smaller than the size covered by the baffle 72. By setting the diameter, the baffle 72 can completely cover the fixing ring 76. Through the arrangement of the exhaust structure 7, the water tank... After the internal heating reaches a certain temperature, a certain amount of gas will be generated. This gas will be transported through the vent pipe 75. As the gas is transported through the vent pipe 75, it will exert force on the baffle 72 and drive the connecting rod 73 and the fixing plate 71 to move, so that the baffle 72 moves away from the surface of the fixing ring 76. At this time, the gas will pass through the fixing ring 76 and be discharged to the outside. When the gas pressure is low, the elastic force of the spring 74 can drive the baffle 72, the fixing plate 71 and the connecting rod 73 back to the starting position, so that the baffle 72 can seal and block the fixing ring 76 again.

[0025] Several fixing blocks 12 are fixed on the outer surface of the oil tank 6, and the inside of the fixing blocks 12 is fixed to the surface of the connecting pipe 4. By setting the fixing blocks 12, the connecting pipe 4 can be fixed to the surface of the oil tank 6.

[0026] A drain outlet 9 is provided on one side of the water tank 8. A rubber stopper 5 is installed inside the drain outlet 9. The drain outlet 9 and the rubber stopper 5 make it convenient to replace the water in the water tank 8 after long-term use.

[0027] It is worth noting that the technical features proposed in this technical solution, such as the diesel engine body 1 and the fuel tank 6, should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0028] Working principle: When operating the diesel engine 1 in winter, the operator first needs to activate the heating plate 11 to heat the concentrated brine inside the water tank 8. When the water tank 8 is heated to a certain temperature, it will generate gas, which will be transported through the vent pipe 75. As the gas is transported through the vent pipe 75, it will exert force on the baffle 72, causing the connecting rod 73 and the fixing plate 71 to move. This will move the baffle 72 away from the surface of the fixing ring 76, allowing the gas to pass through the fixing ring 76 and be discharged to the outside. When the gas pressure is low, the elastic force of the spring 74 will cause the baffle 72, the fixing plate 71, and the connecting rod 73 to move. The connecting rod 73 returns to its starting position, causing the baffle 72 to reseal and block the fixing ring 76. Subsequently, the heated water tank 8 will transfer heat to the fuel tank 6 through the heat conduction plate 10, thereby preheating the fuel tank 6. This prevents the diesel engine 1 from failing to start due to low oil temperature. After the diesel engine 1 starts, the operator can turn off the heating plate 11. Subsequently, the diesel engine 1 will generate gas during operation, and the generated smoke will be discharged to the outside through the exhaust pipe 3. Some of the discharged smoke will enter the interior of the connecting pipe 4, thereby insulating the fuel tank 6 to ensure the normal operation of the diesel engine 1 in winter.
