DETAILED DESCRIPTION

[0022] As shown in Figure 1 , 3 , the utility model discloses a power supply vehicle without external power supply cooling cabin 02, including chassis vehicle 01, cooling cabin 02 and power generation device 03, cooling cabin 02 is installed on chassis vehicle 01, and power generation device 03 is installed in cooling cabin 02, and cooling cabin 02 is provided with air inlet passage 21 and air outlet passage 22, and cooling cabin 02 generates air pressure difference with the outside when power generation device 03 generates electricity, and outside air enters from air inlet passage 21 and is discharged from air outlet passage 22 to carry out cooling circulation.

[0023] Cooling cabin 02 is rectangular parallelepiped, and is firmly installed on chassis vehicle 01, and chassis vehicle 01 selects 8x4 II type chassis vehicle 01 with good mobility and bearing capacity as carrier, to ensure that the power supply vehicle can stably travel under different road conditions, and power generation device 03 is firmly installed in cooling cabin 02, to facilitate coping with various emergency power conditions. Air inlet passage 21 is arranged at one end of cooling cabin 02, and air outlet passage 22 is arranged at the opposite end of cooling cabin 02. Air inlet passage 21 is arranged above the right end of cooling cabin 02, and the lower portion of air inlet passage 21 is the door of cooling cabin 02, which can be used to enter cooling cabin 02, to facilitate checking the condition in cooling cabin 02 and maintaining power generation device 03, and air outlet passage 22 is arranged at the left end of cooling cabin 02. Cooling cabin 02 is made of double-layer heat insulation material, which not only can effectively prevent heat from being dissipated to the outside, but also can protect the internal equipment from physical damage from the outside. The inner layer is high-temperature resistant heat insulation cotton, and the outer layer is high-strength heat insulation metal plate. The combination of the two can not only ensure good heat insulation effect, but also enhance the structural strength of the cabin.

[0024] When supplying power, the current output end of the power supply vehicle is communicated with the external power port, and power generation device 03 is started to generate electricity. Since cooling cabin 02 has certain airtightness, the air in cooling cabin 02 flows under the action of power generation device 03 when generating electricity, so that a certain air pressure difference is formed between the inside of cooling cabin 02 and the outside. Under the action of the air pressure difference, outside air flows into cooling cabin 02 through the air inlet passage 21 at the right end, cools the internal heating components, and is discharged from the air outlet passage 22 at the left end after flowing through the entire cooling cabin 02, to realize the cooling circulation of cooling cabin 02 without external power supply.

[0025] As shown in Figure 1As shown, the cooling cabin 02 intake passage 21 is provided with an air intake filter 24 and an air intake silencer 23.

[0026] The air intake filter 24 is installed at the right end of the air intake passage 21, which can effectively filter impurities in the air and ensure that the air entering the cabin is clean. The air intake silencer 23 is installed at the left end of the air intake filter 24, which can effectively reduce noise pollution when the power supply vehicle is powered.

[0027] As shown in Figure 1 , 2 The power generation device 03 includes an engine 32 and a generator 31, which are arranged in the cooling cabin 02. The engine 32 drives the generator 31 to rotate for power generation.

[0028] The engine 32 and the generator 31 are firmly installed at the left and right ends of the cooling cabin 02 through supports or bolts. Of course, the positions of the two can be exchanged. When the engine 32 is installed at the left end, the air enters from the right end of the air intake passage 21, and then needs a longer path to flow to the left end of the engine 32. This is conducive to the circulation of cold air in the cooling cabin 02 and increases the contact time of cold air with the heat generating equipment in the cooling cabin 02, which can better remove heat. The output shaft of the engine 32 and the input shaft of the generator 31 are meshed by gears. To ensure the stability and firmness of the connection between the two, a support seat can be arranged at the meshing position of the output shaft of the engine 32 and the output shaft of the generator 31 to support the connection. The differential gear can be installed in the support seat as needed to ensure that the generator 31 will not be overloaded due to the excessive speed of the engine 32. When working, the engine 32 drives the generator 31 to rotate for power generation to ensure stable power supply of the power supply vehicle.

[0029] As shown in Figure 1 The cooling cabin 02 is provided with a flow guide passage 25 at the top end, and the flow guide passage opening 26 is arranged towards the exhaust passage 22. The engine 32 is provided with a first air inlet 321 and an engine exhaust port 323. The first air inlet 321 is arranged at the bottom of the flow guide passage 25 and communicates with it. The engine exhaust port 323 communicates with the exhaust passage 22 of the cooling cabin 02.

[0030] The flow guide passage 25 is firmly fixed on the top of the cooling cabin 02 by bolts or welding. The flow guide passage 25 is provided with a flow guide passage opening 26, and the opening direction is towards the left end of the exhaust passage 22, i.e. towards the left end. The engine 32 is located below the flow guide passage 25. The first air inlet 321 of the engine 32 extends upwards and communicates with the bottom of the flow guide passage 25. The engine exhaust port 323 extends to the left and communicates with the exhaust passage 22. The engine exhaust port 323 can be provided with two to improve the exhaust efficiency. Such arrangement makes the structure of the power supply vehicle more compact and improves the utilization rate of the space of the cooling cabin 02.

[0031] When the power supply, start the engine 32 after the generator 31 to start power generation, the engine 32 needs to work through the first air inlet 321 sustained inspiration, because the first air inlet 321 is located in the cooling cabin 02, thus making the cooling cabin 02 in the air pressure drop, with the outside air pressure difference, the outside cold air from the air inlet channel 21 through the air inlet filter 24 after filtering into the cooling cabin 02, and from the cooling cabin 02 right end to the left end, for cooling the cooling cabin 02 in the heat generating equipment (such as: engine 32 and generator 31) cooling, then from the flow channel opening 26 into the flow channel 25, then under the suction of the engine 32, the air in the flow channel 25 through the first air inlet 321 of the engine 32 into the engine 32, the engine 32 after work through the engine exhaust port 323 to the exhaust channel 22, finally through the exhaust channel 22 to the cooling cabin 02 outside, form a from the cooling cabin 02 right end to the left end of the independent air cooling cycle, in remote areas or no external power supply environment can be real-time, efficient cooling of the cooling cabin 02 in the heat generating equipment, so that the equipment is always at a certain working temperature, reduce the wear and tear, failure and so on due to overheating, ensure that the power supply vehicle can continuously and stably supply power to the outside, so as to improve the power generation efficiency and equipment service life.

[0032] As shown in Figure 1 The engine 32 is provided with a second air inlet 322, and the second air inlet 322 is arranged on the side wall of the cooling cabin 02.

[0033] In order to avoid the engine 32 from the first air inlet 321 to suck too much hot air and cause the temperature to be too high, the engine 32 is also provided with a second air inlet 322, and the second air inlet 322 can be provided with one or more, the second air inlet 322 is arranged on the front side wall or / and the rear side wall of the cooling cabin 02, the engine 32 sucks the hot air in the cooling cabin 02 through the first air inlet 321 and sucks the cold air from the outside through the second air inlet 322 to work, through the combination of hot air and cold air, to ensure that the temperature of the engine 32 will not be too high, and the valve that can control the flow of gas can be arranged on the first air inlet 321 and the second air inlet 322, so as to more efficiently control the temperature of the engine 32 and ensure that it can continuously and stably drive the generator 31 to generate electricity.
