[0048] Since the solar photovoltaic panel 5 is located at a high position and needs its surface to be in contact with sunlight, dust will form on the surface of the solar photovoltaic panel 5 after a long period of use, thereby reducing the charging efficiency.

[0049] In order to solve the above problem, an implementation method of this embodiment is proposed, the millimeter wave radar vehicle detection equipment also includes: a cleaning mechanism; the cleaning mechanism is arranged inside the fixing plate 6, and is used to clean the surface of the solar photovoltaic panel 5.

When the millimeter-wave radar detector 2 detects that a large vehicle is approaching, the first motor 8 is started at the same time as the large vehicle moves. The output end of the first motor 8 drives the screw 7 to rotate, and the screw 7 causes the nut 9 to move upward. The nut 9 causes the rotating member 10 to rotate slightly clockwise through the sliding between the cylindrical pin and the slide groove. The rotating member 10 drives the millimeter-wave radar detector 2 to rotate, so that the small vehicle behind the large vehicle can be detected. The remaining millimeter-wave radars are no longer needed for matching, which is easy to use.
