    ARRANGEMENT FOR PRESSURE-CONTROLLED FLOW CONTROL IN WATER SUPPLY SYSTEMS
    The invention relates to an arrangement for pressure-controlled flow control in water systems, preferably in weirs and other water retention systems.
    On weirs or other water storage systems are very often used for flow control height-adjustable, vertical slide. With the raising of the slide, the passage opening is increased and thus can drain a larger amount of water per unit time. These systems are manually operated or require a relatively high cost of materials in a non-manual operation. So z. B. in DE 39 37 685 A1 describes a backwater weir to Vorflutern. Here, in the course of an inflow / outflow line, a weir flap is arranged, which enables unimpeded outflow from the sewer system to the receiving water at normal water level and closes the weir at high water level. For this purpose, a separate control shaft is provided, which is connected in case of flood with the receiving water. In the control shaft coupled to the hinge axis of the weir flap weight body is arranged, which experiences a buoyancy force in the event of flood of the entering water in the control shaft and thus actuates the weir flap.
    The object of the invention is to provide an arrangement for pressure-controlled flow control in water retention systems, which automatically adapts the drainage diameter to the inflowing into the water retention system amount of water. In this case, all components should be rounded in particular in this process, so as to avoid injury to swimming through fish.
    The object is solved by the features of the main claim. By the elastic tube of the receiving unit, the flow opening can be reduced or increased by the elastic tube is pressurized, the elastic tube thereby increases and thus reduces the flow opening or the pressure within the elastic tube is discharged and thus increases the flow opening , The receiving unit can be easily replaced by under the support plate in the inner circle z. B. a wooden element is clamped and thus the entire receiving unit is removed from the structurally existing drain opening.
    Due to the elastic tube there are good curves in which fish passing by can not be injured.
    The control or regulation of the change in the internal pressure in the elastic tube via a pneumatic system or a hydraulic system, which is connected to a water level meter whose measuring signals are transmitted to a control or regulation unit of the pneumatic system or hydraulic system and thus in a change in the Water level height makes a corresponding change in the pressure conditions.
    Advantageous embodiments of the arrangement are listed in claims 2 to 4. In the development according to claim 2, a commercially available, inexpensive motor vehicle air hose is used as elastic hose. This is a low cost option. According to claim 3, the pneumatic system or the hydraulic system is connected to a water level meter, which transmits measurement signals to a control or regulation unit of the pneumatic system or hydraulic system. Thus, the outflow control can be done automatically. In the embodiment according to claim 4, the receiving unit and the support plate of juxtaposed trapezoidal and interconnected sub-elements. With a corresponding small-part design, an approximately circular design can be achieved. The sheet metal processing is easier to carry out than in a completely circular design.
    Several embodiments of the invention are illustrated in the drawings and will be described in more detail below. The drawings show: FIG. 1 a three-dimensional plan view of the receiving unit with a tube inserted and FIG
    Bearing disk, FIG. 2 shows a sectional view through one side of the receiving unit with a pickled unit
    Hose, Fig. 3 is a perspective view of one half of the receiving unit consisting of trapezoidal sub-elements, Fig. 4 is a spatial plan view of a halved receiving unit with inserted
    Hose at low pressure and Fig. 5 is a spatial plan view of a halved receiving unit with inserted hose at high pressure.
    The receiving unit 1 consists of an inwardly open hollow ring 3 made of plastic or a sheet metal version. On the top of this hollow ring 3, a support plate 4 is attached. This support plate 4 prevents the slipping of the receiving unit 1 through the drain opening of the water retention system. A removal of the complete receiving unit 1 from the water retention system is z. B. by a piece of wood, which is placed under the inner circle of the support plate 4 and can serve as a handle when removing the receiving unit 1.
    In the hollow ring 3, an elastic hose 2, z. B. a motor vehicle air hose 2 is inserted. This elastic hose 2 can be inflated by means of a pneumatic system or a hydraulic system and thus increased. This reduces the passage opening for the water drainage. Advantageously, the pneumatic system or hydraulic system is equipped with a control or regulating unit, which receives measurement signals from a water level meter. According to these measurement signals, the control or regulation unit of the pneumatic system or hydraulic system reacts with an increase or decrease in the pressure in the elastic hose 2.
    The hollow ring 3 and the support plate 4 may advantageously consist of aneinan-dergereihten trapezoidal and interconnected sub-elements made of sheet metal in a variant. These sheet metal elements can be produced from a large number of identical elements and can thus be produced inexpensively.
