Abstract
A monitoring sensor rail bracket 8 comprising a mechanism which moves a component to protect a reflective surface 4 of a monitoring rail sensor; and a fan 9 activating and powering the mechanism by using a flow of air created by a passing train. The mechanism may protect the reflective surface by moving a prism of the sensor so that the reflective surface is not facing the coming train; or by moving a physical cover in front of the reflective surface. The mechanism may transfer the power from the fan by using an arrangement of cogs (14, 15, figure 5). The mechanism may have a rubber band (11 figure 5) attached which allows for the prism or cover to return to the original position once the train has passed. This allows an increase in the time before the sensor has to be clean of dirt and reduces the necessity of staff attendance on the track for maintenance purposes.

Mounting bracket for optical monitoring sensor
This invention relates to monitoring sensor mounting bracket that protects the sensor from getting dirty.
In rail industry it is common to monitor the movement of rail tracks to ensure the safety of train movement. One of the monitoring methods is using optical geodetic instruments to check the position of the track.
In order to achieve that, sensors are attached to the rails. Geodetic instruments (total stations) are used to measure distance and angle to the reflective surface of the sensor. Based on those measurements, coordinates can be calculated and compared to the base values to show the movement of the sensor in three dimensions. Dust and dirt moved by the passing train is embedding on the reflective surface. This is mainly applicable to sensors which reflective surface is facing the oncoming trains. The dirt causes the sensors to be useless until cleaned because the geodetic instrument cannot take accurate readings to the reflective surface if it is completely covered.
To extend the time before sensors get too dirty to be useable, this invention proposes using a bracket with a mechanism that protects the reflective surface while a train goes past, by either rotating the prism so that the reflective surface is no longer facing the oncoming train or by covering that reflective surface. The mechanism uses a fan rotated by a gust of wind, created by a passing train, to rotate the prism or a cover. The gust of wind works as both, the power source of the mechanism and the trigger for the mechanism to start working. This is to ensure that the sensor's reflective surface is visible while there are no nearby trains, so that the total station can get the readings, and that it is protected while a train is passing by.
The mechanism will significantly increase the time before the sensor has to be cleaned which reduces the necessity of staff attendance on the track for maintenance purposes.
For best results the mechanism should use different sets of cogs for the sensor attachment and the fan to allow for less force to be needed to move the prisms or the cover.
Preferably the rotating axis of the sensor is in line with the centre of the sensor so that the readings are not distorted in case the total station takes measurements while a train is passing by.
An example of the invention will now be described by referring to accompanying drawings:
• Figure 1 shows a side view of a monitoring prism attached to a rail for monitoring purposes without the proposed bracket • Figure 2 shows a front view of a monitoring prism attached to a rail for monitoring purposes Without the proposed bracket • Figure 3 shows a side view of a monitoring prism attached to a rail for monitoring purposes with the proposed bracket • Figure 4 shows a front view of a monitoring prism attached to a rail for monitoring purposes with the proposed bracket • Figure 5 shows details of the mechanism with the prism facing front while a train is not passing by • Figure 6 shows details of the mechanism with the prism facing down while a train is passing by
A bracket with a rotating mechanism 8 is attached to a regular bracket 7 attached to a track clip 6 which is fixed on the side of the rail 5. While there are no trains nearby the prism 12 is facing the intended direction with the reflective surface 4 pointed towards the geodetic instrument (as shown in figure 5). The prism is held in that position by a rubber band 11. When a train is passing by towards the prism (direction shown as 1) it causes movement of the air towards the prism 3. The airflow causes the fan 9 to rotate in direction 13 which in turn causes the cog 14 attached firmly to the fan to move in the same direction 16. That causes the cog 15 to rotate in direction 17 together with the prism 12. Cog 14 is smaller than cog 15 to transfer more energy from the gust of wind into rotation and to allow for the rubber band 11 to be stretched. The rubber band 11 is fixed with one end to the static casing 18 and with the other to the rotating cog 15. The movement of the train causes the prism 12 to turn until it reaches the movement limiting element 19 to keep it from spinning any further. In this position the reflective surface 4 is facing down and does not get dirty as fast as it does when facing front. Once the train has passed there is no more force to counter the rubber band 11 which brings the prism 4 back into the intended position. The geodetic instrument takes measurements to reflective surface.
