[0026] 1. In this invention, by incorporating a conductive component, the speed measuring mechanism generates a certain amount of heat due to its continuous operation. The heat dissipation mechanism draws this heat into the collecting hood, and then, through the connecting pipe and telescopic pipe, transfers this heat from the support pipe to the sealing cover. The hot air blowing from the fan blades drives the rotating rod to rotate, which in turn drives the rotating plate to rotate synchronously via the connecting block. Simultaneously, the hot air blowing from the sealing cover heats the lens, maintaining a normal temperature around it. Furthermore, the rotation of the rotating plate causes the cleaning cloth on its surface to clean the outside of the lens. The water mist generated on the surface is wiped away to ensure the lens remains sharp. The heat generated by the measuring mechanism defogging the shooting mechanism and ensuring a constant temperature environment. This improves the sharpness of the shooting mechanism and makes full use of the generated heat energy, further reducing energy consumption and the operating cost of the measuring device. While defogging, hot air is used to clean the lens with a cleaning cloth, which can prevent dust from adhering to the lens surface and reduce the wear caused by dust. At the same time, the hot air dries the cleaning cloth, ensuring that the lens is not affected by water mist and water droplets during shooting.

[0027] 2、The present application, by setting up the driving assembly, a certain wind force will be generated before the train enters the tunnel, at this time under the action of the wind scoop will be driven by rotating column screw column in the inner wall of the placement box rotation, with the rotation of the screw column, the screw column will be through the external thread thread sleeve upward displacement, at this time the thread sleeve will be driven by the support rod moves up the fixed rod, in the fixed rod under the support tube will drive the sealing cover up, in the rotating column will drive the transmission gear rotation, at this time the moving rack under the driving of the transmission gear through the sliding rod in the bottom surface of the placement box inner wall sliding, thereby moving the push plate when the sealing cover just lose the block of shooting mechanism, the first magnet and the second magnet attracted, then the push plate under the driving of the moving rack will be pushed to the shooting mechanism, at this time the shooting mechanism through the sliding block in the sliding slot moves, the sliding block under the action of the pulley will reduce the friction with the bottom surface of the sliding groove, so as to push the shooting mechanism to the side wall of the placement box, at this time the train is shot. When the wind force generated by the train gradually disappears, at this time the torsion spring will be through the fixed block makes the rotating column reverse, so as to make the rotating column back to the original position, in the process of reverse rotation of the rotating column on the transmission gear of the rotating column makes the moving rack under the action of the sliding rod back, because the first magnet and the second magnet at this time in the state of attraction, therefore will pull the shooting mechanism in the sliding groove moves, so as to retract the shooting mechanism into the placement box, at the same time the sealing cover will be blocked by the lens of the shooting mechanism under the action of the screw column and the thread sleeve, the wind energy into kinetic energy, to drive the internal structure to work, make full use of natural resources, so as to achieve the purpose of saving resources, reduce the loss of electric power energy, and without power supply, can further reduce the fault rate of interval speed measuring device when working, in the realization of driving can be driven at the same time to different components, and ensure its normal operation, further improve the stability of interval measurement device when working.

[0028] 3、The present application, by setting up the oil outlet assembly, after the sliding rod moves to a distance will push the second fixed plate, with the movement of the second fixed plate will drive the support plate to the inside of the fixed box moves, thereby driving the moving plate to extrude the oil storage bag, the lubricating oil in the oil storage bag after extrusion will flow from the oil outlet hole of the sliding groove to the inner wall of the bottom surface of the sliding groove through the oil outlet pipe, reduce the friction between the pulley and the sliding groove, on the one hand can reduce the wear of the pulley, on the other hand can ensure that the moving rack back can be through the attraction between the first magnet and the second magnet to retract the shooting mechanism, so as to ensure the stability of the device.

[0029] In summary, the application drives the assembly by designing the sliding block and pulley structure to achieve the shielding effect after the shooting mechanism is recovered, so as to protect the shooting mechanism during the process of not using, reduce the abrasion of the lens caused by dust in the air, and collect the heat generated by the measuring device during work by the conducting assembly and the gathering cover, then adjust the temperature around the lens by using the heat, so that the inside and outside of the lens are in a dry state, effectively avoiding the influence of water mist on the clarity of shooting, and the oil outlet assembly can further reduce the friction between the pulley and the sliding groove during the movement of the shooting mechanism, increase the sliding property of the pulley, and reduce the abrasion of the pulley.
