Background
Many of the control functions of a locomotive may be implemented by installing radar (e.g., automatic measurement of locomotive wheel diameter, adhesion control, etc.) because radar can obtain the true ground speed of the locomotive. However, when the radar probe is covered by dust or ice and snow, if the radar probe cannot be removed in time, the use effect of the radar can be affected. Manual cleaning in real time is not possible because the locomotive is in operation most of the time.
The radar cleaning device has the advantages that the mode of blowing and cleaning the radar by using compressed air exists in the prior art, and the air compressor is matched with the radar, so that the compressed air provided by the air compressor enters the radar from the air passage to achieve the function of blowing and cleaning the radar. However, the above-mentioned techniques have the following disadvantages: an air compressor is required to be arranged separately; the device is free of a dirt detection device, compressed air always sweeps the radar, and energy waste is caused; the problem that the sweeping effect is poor due to the fact that the radar probe is covered with ice and snow in winter cannot be solved.
