Problems solved by technology
[0003] At present, in order to prolong the service life, the speedometer used on the road will be protected by a protective case, such as the heat-proof protective cover body of a road speedometer disclosed by the announcement number CN211719026U, but the protective cover is not convenient for adjusting the speedometer after the speedometer is assembled. The shooting direction and angle bring inconvenience to the installation and debugging of the speed measuring equipment, and the cover plate transparent plate set by the protective shell is easy to adhere to dust during use, or the mud produced by the mixture of rainwater and dust cannot guarantee the clear shooting of the speed measuring device To this end, we have designed a speed measuring device for highways to solve the above problems

The invention discloses speed measuring equipment for a highway, and belongs to the technical field of highway equipment. A heat insulation plate is fixedly connected to the inner wall of a speed measuring instrument protection shell, a fan and a transparent plate are fixedly connected to one surface of the heat insulation plate, an air guide groove is defined by the surface of the heat insulation plate and the inner wall of the speed measuring instrument protection shell, and one end of the air guide groove communicates with an air blowing hole; according to the speed measuring equipment for the expressway, the fan can cool the interior of the speed measuring instrument protection shell, blown air directly purges the surface of the transparent plate through the air guide groove and the air blowing holes, the functions of dust removal and water removal are achieved, it is guaranteed that the transparent plate is clear and transparent, and the speed measuring equipment for the expressway is high in practicability. And the inclination angle and the rotation direction of the tachymeter protection shell can be adjusted through the arranged shaft seat, the rotating disc and the adjusting disc, so that the installation and debugging convenience of the speed measuring equipment is improved.
Description
technical field [0001] The invention relates to the technical field of highway equipment, and more specifically, relates to a speed measuring equipment for expressways. Background technique [0002] Highway is a modern term. It is a public road where cars can be driven. Many vehicles such as cars, bicycles, rickshaws, horses, and pedestrians can walk. [0003] At present, in order to prolong the service life, the speedometer used on the road will be protected by a protective case, such as the heat-proof protective cover body of a road speedometer disclosed by the announcement number CN211719026U, but the protective cover is not convenient for adjusting the speedometer after the speedometer is assembled. The shooting direction and angle bring inconvenience to the installation and debugging of the speed measuring equipment, and the cover plate transparent plate set by the protective shell is easy to adhere to dust during use, or the mud produced by the mixture of rainwater and...
