RU2346180C2 - Floating power-generating set - Google Patents

Abstract

FIELD: engines and pumps.

SUBSTANCE: invention relates to water-power engineering and can be used in construction of mobile water power stations. The proposed floating power-generating set incorporates turbines representing the bodies of revolution furnished with the elements regularly arranged on their side surfaces and being in semisubmerged condition in water flow, the said elements being coupled by a flexible joint. Note also that the proposed set comprises a riverbed anchor and a generator fitted on the said flexible joint and linked up with the riverbed anchor with the help of flexible link. The said riverbed anchor transmits, via a flexible cable, generated electric power to loads. Note that the floating turbines are coupled in pairs and arranged cascade-like along the flow and can align themselves relative to the water flow.

EFFECT: exploiting the energy of top water flows without shutting-off water flow section.

Description

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

Known bottom power plant, containing several parallel flexible shafts with hydraulic turbines. During rotation, the turbines sink to the depth of the stream, which does not allow the use of higher speeds in the upper layers of the stream (RU 2164622 C1, 03/27/2001, F03B 17/00).

A device for using the energy of a stream is known, comprising turbines in the form of bodies of revolution with elements uniformly fixed on their side surface, located in the water stream in a semi-submerged state and connected by a flexible connection, a channel anchor and a generator (RU 2261360 C2, 09.27.2005, F03B 13/00). This device is taken as the closest analogue (prototype). The disadvantage of this device is a significant overlap of the living cross-section of the stream.

The objective of the invention is the utilization of energy of the upper layers of the water stream without significantly blocking the living section of the stream.

This problem is solved in a floating hydropower installation containing turbines in the form of bodies of revolution with elements uniformly fixed on their side surface, located in the water stream in a semi-submerged state and connected by a flexible joint, a channel anchor and a generator, in which according to the invention, on a flexible joint a generator has been strengthened, connected by a flexible connection to the channel anchor, which transfers electricity to the consumer through a cable, the elements are flexible, and the turbines are connected in pairs by a cascade of eh flow and formed with the possibility of floating samoustanavlivaniya with respect to the aqueous stream.

The floating hydropower installation is illustrated by the drawings shown in figures 1-4.

Figure 1 shows a turbine with one of the options for flexible elements.

Figure 2 presents a plan of a section of a river with a floating hydropower installation.

Figure 3 shows a plan of floating hydropower plants connected by a cascade.

Figure 4 shows a section aa in figure 3.

The floating hydropower installation contains floating turbines 1, which are bodies of revolution, the specific gravity of which is less than water, coated on the lateral surface by flexible elements 2, interconnected by a flexible connection 3 with a generator 4 mounted on it, which in turn is attached by a flexible connection 5 to channel anchor 6, from which electricity is supplied to the consumer via cable. The turbines 1 are connected in pairs in cascade along the stream and are made with the possibility of self-installation relative to the water stream.

Work floating hydropower installation is as follows.

First, a channel anchor 6 is installed, to which a generator with a flexible connection, which connects the turbines 1, is attached by a flexible connection. Turbines 1, which are in a semi-submerged state, are rotated by the water flow, and due to the flexible elements 2, the area of interaction with the water flow is increased and transmitted rotation through a flexible connection 5 to the generator 4 fixed to it, from which the generated electricity is supplied via cable to the consumer 8.

If necessary, this structure can be transferred to another similar target and used repeatedly to provide local energy and water supply.
