[0029] This device has good sealing performance and prevents foreign matter from entering the unit, specifically:

[0030] The air conditioning unit body 2 is installed above the driver's cab roof panel 1, the rear surface of the air conditioning unit body 2 is provided with an air supply port 3, the side surface of the air conditioning unit body 2 is provided with a condensation air inlet 4, the other side surface of the air conditioning unit body 2 is provided with a filter 11, one side of the filter 11 is provided with a fresh air port 12, the upper surface of the air conditioning unit body 2 is provided with a condensation air outlet 5, the lower surface of the air conditioning unit body 2 is provided with a return air port 6, one side of the return air port 6 is provided with a control interface 19, the baffle 7 is rotatably installed on the surface of the condensation air outlet 5, the surface of the condensation air outlet 5 is an annular grille structure, the rotating shaft of the baffle 7 passes through the surface of the condensation air outlet 5 and is connected to a turbofan 8, and the surface of the turbofan 8 is provided with a cylindrical air guide channel, the sealing strip 9 is a hollow convex strip, the surface of the driver's cab roof panel 1 is provided with a sealing groove 10 with an upper opening, the sealing strip 9 is installed on the inner surface of the sealing groove 10, and the upper end of the sealing strip 9 contacts the lower surface of the air conditioning unit body 2;

[0031] like Figure 1-Figure 6As shown, due to the limited space of the diesel locomotive, the 7kW air-conditioning unit body 2 is installed above the roof panel 1 of the driver's cab, and the upper end of the condensation air outlet 5 is exposed to the external environment. A sealing groove 10 is arranged on the upper surface of the roof panel 1 of the driver's cab, and a sealing strip 9 is installed in the sealing groove 10 to contact the lower surface of the air-conditioning unit body 2. The sealing strip 9 increases the sealing of the connection between the air-conditioning unit body 2 and the locomotive. The control interface 19 can be used to control the air-conditioning mode and adjust the internal temperature of the locomotive. Wind enters from the condensation air inlet 4 on one side, and is discharged from the condensation air outlet 5 on the upper surface of the device after cooling. The grille on the surface of the condensation air outlet 5 intercepts foreign matter from the outside to prevent foreign matter from entering the interior of the air-conditioning unit body 2 and affecting the operation of the device. When air is discharged from the condensation air outlet 5, the air drives the turbofan 8 to rotate from the bottom, and the rotation of the turbofan 8 drives the baffle 7 to rotate on the grille surface.

[0034] like Figure 1 As shown, the condensed water generated by the 7kW air-conditioning unit body 2 is discharged from the condensed water outlet 13 and enters the condensed water tank 14. Since the condensed water only changes in temperature and is not polluted by the external environment, it will not cause harm to the human body. The booster pump 17 is started, and the booster pump 17 pressurizes the condensed water and discharges it into the pipe 15, and sprays it out from the nozzle 16 to humidify the car and increase the comfort of the staff.

A grille is arranged on the surface of the condensation air outlet 5 to intercept foreign matter from the outside, and when air is discharged from the condensation air outlet 5, the air drives the turbofan 8 to rotate, and the rotation of the turbofan 8 drives the baffle 7 to rotate. The rotation of the baffle 7 cleans up the debris dropped from the surface of the grille to prevent the debris from accumulating on the surface of the grille. The condensed water generated by the air-conditioning unit body 2 is sprayed out in atomization through the pressure pump 17 and the nozzle 16 in the condensation water tank 14 to humidify the car, thereby increasing the overall practicality.
