Problems solved by technology

[0002] During the operation of railway trains, when there is a temperature difference between the inside and outside of the train, water mist will often be generated and attached to the glass, which will seriously affect the driver's sight and pose a serious safety hazard; in existing ordinary motor vehicles The defogging method of the windshield usually uses cooling air blown to the windshield through the air outlet arranged on the inside of the windshield, so as to achieve the effect of defogging, but this defogging method is generally suitable for the front windshield with an inclined setting , the cold air blown out from the tuyere can effectively blow the front windshield to form a large area, which can play a better defogging effect; and for some railway locomotives whose front windshield is nearly vertically set, the use of this type of The defogging method cannot effectively defog the window, so it is necessary to design a new defogging device

Embodiment 1

[0032] The invention provides a low-temperature defogging device for a railway locomotive, referring to Figure 1-Figure 4 , as a specific embodiment, the low-temperature defogging device includes a gas collecting hood 1, an air pump 2 and a gas condensing device 3, and the gas collecting hood 1 and the gas condensing device 3 are both arranged on the top of the locomotive cab, The gas collection cover 1 includes an air outlet 10 and an air inlet 11 with the opening facing downwards, and the gas condensation device 3 includes at least one first flow channel 31 and a second flow channel 32 adjacent to the condensation flow channel 31 , the first flow passage 31 includes a first inlet 310 and a first outlet 311 protruding from the roof outside the compartment, the second flow passage 32 includes a second inlet 320 and a second outlet 321, and the outlet The air port 10 communicates with the air inlet end of the air pump 2 , and the air outlet end of the air pump 2 communicates w...

Embodiment 2

[0043] The invention provides a low-temperature defogging device for a railway locomotive, referring to figure 1 , as a specific implementation, it differs from Example 1 in that it also includes a bar-shaped blowing nozzle 4 arranged inside the cab, and the blowing nozzle 4 is arranged on the upper side of the windshield of the locomotive and along the The width direction of the blowing nozzle 4 is arranged horizontally, and the blowing nozzle 4 is provided with an air inlet 42 and a blowing outlet 41 arranged along the length direction of the blowing nozzle 4 and opening downward, and the second outflow port 321 communicates with the air inlet 42 . Through this setting method, the dehumidified gas can be blown downward from the blowing port of the blowing nozzle, so that a protective layer of dehumidified gas can be formed on the surface of the windshield, which can achieve a better defogging effect.

Embodiment 3

[0045] The present invention provides a low-temperature defogging device for a railway locomotive. As a specific implementation, it differs from Example 1 in that reference figure 1 , Figure 4 , as a preferred embodiment, the device also includes at least one first temperature sensor 7 arranged in the cab and at least one second temperature sensor 8 arranged outside the compartment, the first temperature sensor and the second The temperature sensors are all electrically connected with the control device. Through this setting method, the air temperature inside and outside the cabin can be detected by the temperature sensor and transmitted to the control device. The control device can analyze the detection value of the first and second temperature sensors and the detection value of the humidity sensor. When the water mist tends to automatically control the air pump to dehumidify the gas in the cab, so as to achieve an automatic and intelligent demisting effect.

Abstract

The low-temperature demisting device comprises a gas collecting hood, a gas pump and a gas condensing device, wherein the gas collecting hood and the gas condensing device are both arranged at the top of a cab of the locomotive, the gas collecting hood comprises a gas outlet and a gas inlet with a downward opening, the gas condensing device comprises at least one first flow channel and a second flow channel adjacent to the condensing flow channel, the first flow channel comprises a first inlet and a first outlet which extend out of the roof and are located outside the compartment, and the second flow channel comprises a second inlet and a second outlet. The air outlet is communicated with the air inlet end of the air pump, and the air outlet end of the air pump is communicated with the second inlet, so that water vapor in air in a cab can be removed through the low-temperature demisting unit and water mist can be prevented from being formed on a car window, and therefore the effective demisting effect can be achieved.
