    The invention relates to a reflector arrangement for guide posts with at least one retroreflective reflector, a viewing surface, a cleaning device for cleaning the visible surface and a wind turbine, which is connected to a transmission.
    Guiding posts for the limitation of traffic routes are typically equipped with reflectors to ensure an orientation of the road users even in darkness and poor visibility. However, they are only effective if they are not contaminated by dirt, Conventional reflectors must therefore be regularly cleaned by road service, which is correspondingly expensive. There is therefore a need to use guide posts whose reflectors are cleaned automatically and without the supply of energy, ie are self-cleaning. Thus, various guide posts have become known in which wind energy is used to drive a cleaning device. The wind energy can come from the natural wind, but also - for example, in tunnels - be formed by the flow, which is caused by the passing motor vehicles.
    WO 00/06831 A shows a guide post, the reflector is cylindrical and rotatably arranged. A wind turbine is connected to the reflector and drives it. The disadvantage here is that at the wind turbine, a relatively large torque must be available to enable the reflector in rotation, so that at expected wind speeds of typically 2 m / s to 6 m / s, by scientific studies of the Institute of Transportation at the University of Agricultural Sciences in Vienna have been determined, no acceptable function can be achieved. Similar disadvantages also apply to solutions as described in KR 90 125 987 A and in CN 201 722 633 U. If a proper operation of the cleaning device can be achieved, a corresponding wear of the reflector is to be expected due to the high speed, which destroys this in a short time, as it goes blind.
    From WO 03/004 777 A a Leitpost is known, which is equipped with a wind turbine. Via a special gear, a cleaning device 1/16 2 is operated, which is guided over the reflector to clean it. In this cleaning, the reflector is partially or completely covered and thereby impaired in its effectiveness. Moreover, this device is complex and prone to failure.
    The object of the present invention is to avoid these disadvantages and to provide a solution which on the one hand enables efficient cleaning and on the other hand has a simple and robust construction. In particular, the life of the reflector should not be affected by the cleaning, since it is inherently not only expensive for Wegerhalter to ensure a regular cleaning of the reflectors, but also prematurely blinded reflectors to replace.
    According to the invention, these objects are achieved in that the visible surface consists of a cylinder rotatable about its axis, which can be driven by the wind turbine via the transmission in order to move the cylinder past cleaning elements of the cleaning device.
    Essential to the present invention is the fact that the visible surface is not covered during cleaning and therefore it can not happen even in calm, that a cleaning element covers the reflector for a long time. Another essential aspect of the invention is the fact that a relatively high torque can be provided by the transmission even at relatively low wind force in order to carry out the cleaning efficiently. As a result, effective cleaning of the reflectors can be ensured even at relatively low wind speeds. It is also no permanent rotation required to ensure the desired self-cleaning. In terms of service life, it is particularly important that the rotational speed of the cylinder through the transmission is relatively greatly reduced, typically in a ratio that is between 1:50 and 1: 200.
    A particularly simple and robust construction can be achieved in that the transmission is designed as a planetary gear, preferably as a double planetary gear. Another advantage of this solution is that the cylinder and the wind turbine can be arranged coaxially with each other without special technical measures. 2/16 3
    A particularly preferred embodiment of the invention provides in this context that the planetary gear a first stationary ring gear, a second, concentric ring gear, which drives the cylinder, at least one planetary gear meshing with both ring gears and one connected to the wind turbine and meshing with the planet gear Sun wheel has. Such a transmission is also referred to as Wolfrom transmission. The peculiarity of such a transmission is that two coaxial ring gears are provided which have a small difference in the number of teeth, which is typically one or two.
    It has also proved to be particularly advantageous when the cylinder is cantilevered. This means that the cylinder is mounted hanging only on the transmission and down, for example, is guided only by the cleaning elements. If necessary, it is also possible to limit the deflection of the cylinder by means of a cone-shaped receptacle.
    In a first preferred embodiment of the invention, the surface of the cylinder is designed as a reflector. The reflector is thus cylindrical to manufacture, which means increased complexity in this regard, but the structure is much easier.
    The cylindrical reflector is formed from retroreflective glass beads disposed on the circumference of the cylinder or, alternatively, retroreflective sheeting applied to the circumference of the cylinder or, alternatively, plastic injection molded articles with internal retroreflective elements.
    By inserting corresponding diaphragm elements into the shaft of a guide post in front of the reflector, the visible reflector surface can be adapted to various relevant national and international standards. For example, different masks and colors can be provided for the incoming traffic. This is also possible by producing the reflective cylinder in different shades, alternatively by constructing the cylinder from variously colored annular elements, foils or glass beads, each visible from different directions. 3/16 4
    Alternatively, it may be provided that the reflector is arranged fixed in the interior of the cylinder. In this case, the cylinder is transparent to ensure the optical connection of the reflector to the outside world. In this embodiment, it is also possible to provide different reflectors for different viewing directions, for example, red reflectors for one direction and white reflectors for the other direction. This also allows the visible reflector surface to be adapted to various relevant national and international standards.
    A particularly high efficiency can be achieved if the wind turbine has a horizontally arranged in use disk from the upwardly projecting blades, which are curved. In particular, it is of great advantage if the blades are internally exposed, that is, if the inner edge of the blades is spaced from the axis of rotation by, for example, between 10% and 20% of the diameter of the disk.
    Preferably, it can also be provided that the cylinder and / or the reflector are provided with a dirt-repellent surface coating. In this sense, for example, a nano-coating may be present. It is an aspect of the present invention that the cleaning elements are arranged rotationally fixed, i.e., that the cylinder rotates past the cleaning elements. However, it is also possible that the cleaning elements comprise rotatable rollers which roll on the cylinder. This can be provided to remove dirt and debris from the cylinder by a special surface coating of the cleaning elements. Apart from the rotational movement about its own axis and these cleaning elements are basically fixed.
    In a particularly preferred manner, it can be provided that additionally a generator is provided in order to generate power for an additional electronic component. This electronic component may, for example, be a transmitter for issuing warning messages, which transmits information about possible dangerous situations via near-field radio to passing vehicles. However, it is also possible to determine measured values, such as temperature values and traffic data, via sensors which are also supplied with power by the generator and to forward these to other guide posts or to a control center. An optimal efficiency is achieved with an additional high-speed wind turbine, which rubs the generator directly to, which therefore can also be designed to run quickly.
    Particularly advantageous is the possibility of the delivery of beeps to keep wild from the traffic areas.
    In the following, the present invention will be explained in more detail with reference to the embodiments illustrated in FIGS. FIG. 1 shows an embodiment variant of the invention; FIG. Fig. 2 shows the embodiment of Figure 1 in a plan view. Fig. 3 is a section along line III - III in Fig. 2; and Fig. 4 and Fig. 5 representations of the transmission in longitudinal section and in cross section, wherein Fig. 4 is a section along line IV - IV in Fig. 5 represents.
    The reflector assembly of Fig. 1 consists of a wind turbine 1, which is rotatably mounted on a gearbox 2. Below the gear 2, a rotatable cylinder 3 is provided, on the side of cleaning elements 4 rest in order to clean this. The rotatable cylinder 3 and the cleaning elements 4 are arranged in a housing 5, which is detachably connected on its underside with a guide post 6 only indicated here.
    The wind turbine 1 consists of a disc 7 rotatably mounted about an axis 7, on which a plurality of curved blades 9 are mounted, which project upwards. The wind turbine 1 is substantially cylindrical on the outside and closes the stationary housing 5 flush on its upper side. At the top of the housing 5, the gear 2 is provided, which will be explained in detail below.
    At the bottom of the transmission 2, a cylinder 3 is suspended, which is driven by the wind turbine 1 via the transmission 2, wherein the rotational speed of the cylinder 3 due to a large reduction ratio of the transmission 2 is about a factor of 100 smaller than the rotational speed of the wind turbine first ,
    In the housing 5, two cleaning elements 4 are mounted, which are supported on the housing wall 5/16 6 via springs 10, which are formed as integrally molded leaf springs. On the cleaning elements 4 brushes or rubber lips 11 are mounted, which are intended to clean the cylinder 3, which rotates past the cleaning elements 4. Alternatively or additionally, textile lips may also be provided for cleaning the cylinder 3.
    At the bottom of the housing 5, a mandrel 12 is provided, which has a clearance relative to the cylinder 3 both in the radial direction and in the axial direction. The mandrel 12 is guided in a recess 13 which is formed by an inwardly projecting projection 14.
    As can be seen from Fig. 1, the housing 5 has laterally two recesses 15 through which the cylinder 3 is visible, wherein the outer surface of the cylinder forms the visible surface 17. The cylinder 3 is coated on its outer periphery with a retroreflective material or made entirely of such a material. This material thus forms the reflector 16. During assembly, the reflector assembly is aligned so that the desired reflective properties are achieved for the relevant road users, i. in particular, that the recesses 15 are oriented in the direction of the incoming traffic.
    Now, the structure and the function of the transmission 2 will be explained in more detail. In a fixed first ring gear 20, two planet gears 21 run, which are driven by a sun gear 22 which is rotatably connected to the turbine 1. Coaxially and immediately below the first ring gear 20, a second ring gear 23 is provided which has a slightly smaller diameter than the first ring gear 20. Also, the number of teeth is two lower than that of the first ring gear 20, which has, for example, 200 teeth, compared to 198 teeth of the second ring gear 23. The planet gears 21 mesh with a corresponding remote teeth also with the second ring gear 23 and drive this with a correspondingly small Angular velocity. In this way, a very large reduction can be achieved with simple means. The cylinder 3 is connected directly to the second ring gear 23.
    This large reduction of the gearbox 2, in addition to a corresponding increase in the torque has the particular advantage that the wear of the cylinder 3 by the cleaning elements 4 keeps within narrow limits. By not shown connecting elements, the reflector assembly is inserted, for example, in a guide post 6, which is arranged at the roadside. Regular cleaning is no longer required due to the design according to the invention, but any maintenance can be made easily and inexpensively due to the modular design.
    As stated above, the cylinder 3 may also be transparent, in which case retroreflective elements not shown here are provided in the interior of the cylinder, which are visible to the road users through the cylinder 3. 7/16
