Description

&iacgr;&ogr; Flood protection system

The invention relates ^to a flood protection system with one or more protective elements according to the preamble of claim 1. In particular, the invention relates to such a system in which flood protection is established ^by means of protective elements that ^can be folded vertically. ■ ^; ;'■'■

Flood protection is a long-standing and recognized problem _, particularly in densely populated areas at risk of flooding due to rivers/lakes or their proximity to the sea. While in areas with frequent risk potential, particularly in coastal areas with a risk of storm surges, dikes with a protective height corresponding to the maximum risk potential are used, it has long been common practice to limit oneself to emergency measures in areas with only occasional flood risk potential, e.g. by sealing off areas with sandbags in the event of acute danger. Particularly along rivers and other bodies of water with a similar risk potential.

significant damage was to be feared. Due to this controlled flooding, the flood level was lowered massively in the endangered areas, and thus the acute risk potential _was reduced. ■■'.;.. . : ·.·· ;. .·' ,. ■ ■ .';■ ■'■■: ■ ■ ■ _'"■ .■ /■ \ .. . ···'.·■■■'

^: " Due to the increased pressure of civilization, however, the designation of .corresponding flood areas became more and more difficult, so that in the last few years in many places

Basically, it is known that with such structural measures, protection zones against flooding can be created, so that the protective elements can be completely or partially lowered without acute danger. There are basically two different ways of doing this:

■ whereby - depending on the possible structural conditions - preference should be given to one or the other type of protection.

: From DE-195-14 205 Al, for example, a structural measure ^with folding elements is known, in which a receiving chamber comprises, on the one hand, a floodable floating chamber and, on the other hand, a swivel chamber, and the swivel element is swiveled from the horizontal to the vertical. The structural measure described there is based on the basic idea of causing or at least supporting the swiveling out by the floating up of the protective wall in the floating chamber, which is made of pontoon parts. Even if such a measure can be seen as simple ^, it is nevertheless, with the

The disadvantage is that a controlled swinging _out and back of the protective elements is not supported in every case. However, for safe protection it is necessary that the swinging out measures are supported by various instructions and/or measures, including safety-related ones (manual operation on site, central operation of a control unit).

However, the measures proposed in DE 195 14 .205 are not acceptable or only inadequately acceptable for such use.

From WO 99/24675 Al a high-pressure water protection system is known,

This is particularly important when a mobile flood protection system is planned over a longer protection distance, e.g. when surrounding a larger building complex with a fully or largely submersible protective wall or when protecting a larger urban area along ^a river that, for example ^, flows through _the city or district. It is _obvious that if just one of 100 or more protective elements fails ^, the entire protective purpose can be lost. and that, therefore, special safeguards must be planned.·, .

.■■ That. Flood protection system according to the embodiment shown in Figures 1 and 2 has protective elements. The protective elements comprise a pivotable protective plate 2.0 for forming a protective wall in a state pivoted into the vertical 25 and for forming an essentially flat surface _in a horizontal state with no protective effect. The protective plates 20 are attached to a channel element 10, but are designed to be walkable ^and drivable. The protective plate 20 and the channel element 10 are pivotally connected with a rotary or pivot bearing. A drive device 30 carries out the pivoting movement of the protective plate 20 relative to the channel element 10. ■

.The drive device 30 has a drive unit 32 in the upper area of the channel element, which can be used as an electric ^motor - alternatively, or redundantly as a hydraulic or pneumatic motor.
