Floating power plant
(57) Abstract:The power plant is designed to generate electricity using the flow of the river, without affecting the construction of the river and saving the environment. The power plant includes a floating base in the form of pontoons, for example two, linked by bridges, which is movable in a vertical plane fixed impeller turbines connected by a chain transmission with gear drive generator. Wheels can operate in half-submerged condition, and under water. This is achieved by the fact that each blade wheels are made in the form of a series of buckets with blank walls. The bottom of the ladle recruited from shutters, hinged to the walls of the bucket and overlapping each other, with their axes of rotation coincide with the long side curtains and do not coincide with their axes of symmetry and rotation around its axis is limited by stops. The wheel on top of the closed casing, and the bottom has the underlying beam. Beam and the casing open ends and have the brackets and flanges for attachment to the wheel, if there is a need for additional sections. For the sustenance of the plant in emergency situations provides the installation additionally what you first pontoon floating bases attached to the axle of the hinge. The power plant is installed in a worker thread at anchor. Impellers fall into the stream or river bottom, while working in the winter time. The turbine spins a generator and produces electricity. The drive system generator provides stable operation in the automatic mode when the speed of flow and loads to the generator in a wide range. 1 C.p. f-crystals, 5 Il. The invention relates to engineering and can be applied in any region of Russia.Known hydropower station, in which the main structure is a dam across the river. It is built in order to raise to a certain level of the catchment of the river and due to the elevation of water levels before and after dam to get from the river of its energy potential. Negative aspects of hydropower dams known. The alternative it may be hydropower dam, one of the technical solutions of which is the invention.The river itself is often a powerful source of energy and can give its energy potential without building a dam and other complex power structures.Closest in tehnicheskaya - Ryzhukhin R. C.HES on patent N 2002099 consists of the turbine, gearbox, generator systems management. Jet turbine is lowered into the water stream, which is acting on the turbine blades set at an angle to the stream, rotates its shaft, through the promotion of the gear shaft of the generator. However, the application of jet turbines in run-of-river hydropower, hydraulic factor which can not be above 0.5, the failure of a turbine to operate under the ice in winter, do not allow to apply these hydropower plants on the rivers 3-6 order without building on the river complex hydraulic structures.The purpose of the invention is the improvement of the characteristics of the hydropower plant, the impeller which operates under the ice in the free flow of the river.This objective is achieved in that the floating power plant that includes a floating base that hosts working impeller turbines, generators and actuators characterized in that the floating base is made in the form of pontoons, for example two, linked by bridges, which is movable in a vertical plane fixed wheel turbine connected to a generator drive. For example chains, and with pontoons, e.g. the external form, the bottom of which is assembled from overlapping each other, a hinge mounted on the outer forming bucket blinds, whose axis of rotation does not coincide with their longitudinal axis of symmetry and rotation round its axis is limited, for example, a focus, and the shutter is made, for example, in the form of two thin plates connected to each other in the service of the transverse ribs, so that the gaps between the plates through and remain open long sides of the package.Additionally, this objective is achieved in that the impeller turbines are closed on top of solid casing, and the bottom of the underlying beam connected to the casing racks that are attached to the bearings of the impeller and the casing, the underlying beam and turbine wheels and the ends are brackets and flanges to attach additional sections of the turbine.Thus the proposed solution differs from the prototype, therefore it meets the criterion of "novelty."In Fig. 1 shows the side view of the floating power plant; Fig. 2 is a top view of the station and shows the placement of station equipment in the machine room; Fig. 3 shows a portion of the impeller of the turbine, its longitudinal RA the power plant according to the invention consists of a floating Foundation, representing two pontoon-type 1 "catamaran" related to each other in places 2 and 3. Front, in the course of the river flow, the pontoon is connected to the bridge - 2 hinge - 4 /Fig. 2/. On floating base station 1, also placed bollards - 5, winch - 6, engine room - 7, main - 8 and auxiliary - 9, a turbine mounted on a floating base movably in the vertical plane using a pantograph - 10. Raising and lowering of the impellers of the turbine is carried out with the help of tackles - 11.In the machine room station - 7 /Fig. 2/ posted by the main shaft 12 connected to the impeller chain transmission - 13. The main shaft 12, through the cone clutch - 14, is connected with gear - 15, which through a multi-disc friction clutch 16 and the belt transmission 17 is connected simultaneously with the generator 18 and a pump 19.In the machine room is placed, the control station 20, the Cabinet with electrical equipment 21 and the throttle 22, the system control pump 19.Turbine wheel - 8 /Fig. 3 and 4) consists of shaft 23 rotating in bearings 24 attached to the turbine housing - 25. Turbine shaft - 23, a sprocket and chain transmission - 13, connected to the main shaft - 12, drive generator - 18. Chain the additional sections of the wheels, closed covers - 27.The upper part of frame 25, the wheel 8 is a farm - 28, in which the wheel 8, using tackles - 11 /Fig. 1/ can rise above the water, or sink to the bottom of the river. Shaft 23 of the impeller - 8 fixed blades 29 and aperture - 30. Together they form the buckets are mounted in a row along the axis of the wheel. The number of rows of buckets is the number of blades of the wheel. In Fig. 4 of their shows 12 pieces. The bottom of each bucket may be made oval or be direct, as shown in Fig. 4, however, in that and in other case made of overlapping hinged to the side walls of the bucket, blind - 31. Blinds rotate on their axes freely in their joints and their rotation is limited by stops /Fig. 4 - not shown/. Each curtain is made in the form of two thin plates - 32 /Fig. 5/ connected by an edge 33. The ends of the long sides of the shutters are open and the flow of water passes freely through them. At the same time this design blinds can give it the necessary strength. The casing 25 of the impeller turbines - 8 consists of the underlying beams 34, casing - 35, closing the top of the impeller. Cover with underlying beam with one side connected to the grid in the winter under the ice in the free flow of the river, leveraging the power of the river flow. As noted above, on top of the casing - 36 has a connecting farm - 28, staple - 38, which HPP impeller is suspended from the hook crane or hoist hook - 39.Works floating power plant as follows.Station on the anchors, bollards - 5 and winches - 6, is mounted in river flow. Impeller - 8, electric hoist - 11, is lowered into a river, stream hitting the shutter 31, blades 29, and puts them on the bottom of the bucket and turn the wheel around its axis 23. Passing the working area of the blade wheel rises from the stream under the hood - 35. Not having a load from a stream blinds rotate around its axis on the line of less resistance, which coincides with the tangent to a circle intersecting the axis of rotation of the shutters. The resistance to movement of the shutters in the stream is reduced in many times, many times the size of the blinds more square the ends of its two plates, of which the curtain is made. This allows the impeller of the turbine to work in river flow with high efficiency when fully flooded wheel. At the entrance of the blade into the working area, after it has passed the area covered by a cap, ø the rock is repeated.After the impeller will gain momentum, turns on the coupling 16 of the pump 18. Is artificial inhibition of the impeller. After a high-speed shaft of the gearbox will rotate at a speed that should spin the generator, generating a current of a given frequency, enables the coupling of the generator and the generator. The control system elements 19 and 22 provide stable operation of the generator when the change in a wide range of speeds of the river flow and the change of load in the network generator.
