RU74082U1 - FISHLINE TURBINE DIFFERENT BY APPLICATION OF FLEXIBLE POLYMER TAPES - Google Patents

Abstract

The utility model relates to hydropower and can be used in the construction of mobile hydropower plants. A useful model of a garland turbine consists of flexible polymer tapes mounted on a rigid hoop in the form of a spiral, stiffeners attached to the hoop. The cardan joint is fixed at the intersection of two transverse stiffeners, which are mutually perpendicular and their end parts are attached to the hoop. A garland turbine is installed in a watercourse and held onto the surface by a float, transmitting rotation to a generator installed on the shore outside the flood zone. The proposed garland turbine made of flexible tapes can be used on small streams with a flow velocity of more than 1 m / s for energy supply in remote areas, farms, geological lots, etc.

Description

The utility model relates to hydropower and can be used in the construction of mobile hydropower plants.

A device for garland turbines Blinova BS [1], which is a series of wingrotors (a "rotating wing", two half-cylinders displaced relative to each other) mounted on a cable, the rotation of which drives a generator mounted on the bank of the watercourse. The disadvantage is the low efficiency. During rotation, the wing rotors sink to the depth of the stream and are maintained in this position due to the "hydrodynamic pillow", which does not allow the use of higher speeds in the upper layers of the stream [1].

The closest analogue is the arrangement of a cross-jet helicoidal turbine with spiral blades or a Gorlov turbine. The disadvantage is the rigid mounting of the turbine on the generator shaft or on a floating platform, as well as the complexity of manufacturing [2].

The proposed utility model of a daisy-chain turbine (Fig. 1) consists of flexible polymer ribbons 1 mounted on rigid hoops 2 in the form of a spiral, stiffeners 3 attached to the hoop 2 and is a helicoid turbine. The cardan joint 4 is fixed at the intersection of two transverse stiffeners 5 and 6, which are mutually perpendicular and their end parts are attached to the hoop 2.

Figure 2 shows the plan of the watercourse and the installation diagram of the daisy-chain turbine from flexible tapes. Due to the flexible connection 7 and the gimbal connection 4, turbines 8 are attached, which transmit rotation to the generator 9, it is also provided that the turbines are mounted to the float 10, through which they are placed in the upper layers of the watercourse at higher speeds, which allows more complete utilization of the energy of the water flow.

The proposed garland turbine made of flexible tapes can be used on small streams with a flow velocity of more than 1 m / s for energy supply in remote areas, farms, geological lots, etc.
