Description

1

The invention relates to hydraulic motors of infinite type and can be used as a device for changing the energy of running water into mechanical or electrical energy. Known for the mechanical energy of a running water power plant, for example, from JP56077564 and DE202009003291 U1, which have a housing fitted with two shafts connected by chains on which rigidly fixed blades, which are at the bottom of the chain in working position and immersed in water, rotate over the chain and rotate over in idle mode. Such power plants are fixed on the foundation and this causes difficulties when the water level changes. These power plants must not be used in winter if ice is formed. In addition, by turning the chain, the blades move from the horizontal position to the vertical to the water and roll out with noise. From DE202009002097 U1 is known as a flowing water power plant, the main difference being that it has a pontoon floating platform and makes it mobile. The power plant is still different in that the blades are convex. This alleviates water resistance to blades by dropping them out of the water and dipping, which reduces noise during power plant operation. The water flow divider and the side valves increase the efficiency of the power plant. The power plant according to SU1694972 has a housing with two shafts, an endless band connected by hingedly attached blades, which, when moving from the working conveyor to the idle branch, clamp on one another. The shoulder blades are fitted with sliders that come in contact with the guides attached to the housing. This power plant can be submerged and can operate in winter. One of its major drawbacks is that it relies on the bottom on its own weight or on an additional foundation. In addition, at the power plant blades are fixed on an infinite band, which does not guarantee flexibility of the blades in relation to the direction of the water flow. When the water flow into the blades, the friction forces are created in the guides. In addition, there is a current resistance when the blade blades move in the uppermost position and when the blades move from the clamped position to the unfolded position according to an undefined trajectory. 2

The closest analogue is a mobile flowing water power plant according to RU 2269672, which has a catamaran-shaped body with buoys and a side-to-side turbine with a mechanical drive coupled to an electric generator. The conveyor is lowered to the edge during operation and directed at an angle of 35 ° to the direction of the water flow. The conveyor consists of two parallel vertically-mounted shafts connected together by a transmission element - an endless belt on which the elastic material blades are mounted, hinged at one end and connected at the other end through two flexible elements, forming a bucket shape against the current. As the blades move from the branch of the transporter to the idle branch, they gradually let go and climb on top of each other.

However, the power plant according to RU 2269672 occupies a large surface area of the river, especially not in the working position, when the conveyor is raised above the water as it is mounted near the hull. The area occupied is further increased by the fact that the power plant is built not in the longitudinal direction but in the direction of the current flowing from the angle. This complicates shipping and the power plant cannot operate in a narrow water stream. The power plant is also unable to work in a shallow stream as the conveyor works on the side. In addition, it cannot operate under ice because the body remains on the surface of the water. A complicated power generator drive, as the turbine is mounted next to the catamaran base. The buckle-like elastic material blades are sophisticated and unreliable on the transmission belt, and they also cause additional resistance during idling. The aim of the invention is to create a simpler and more efficient mobile flowing water power plant, capable of operating in shallow, rivers of any width and at various climatic conditions, and to expand its use. The object of the invention is achieved by the use of an underwater conveyor turbine in a fluidized water power plant having a catamaran-shaped housing with buoys, the conveyor having two parallel shafts interconnected by transmission elements hingedly attached to rigid blades which, when moving from the branch of the conveyor to the empty conveyor. rotor, cover each other, the electric generator connected via a mechanical drive with 3 turbine, and the anchors, the turbine is inside the housing and its conveyor shafts are in the horizontal position, the casing is directed against the current and the front has a cover whose front part is in the form of a cut funnel and wraps rotating blades at such a distance that the blades are unobstructed to leave idle to the working position, and where the height of the enclosure is selected to obstruct the action of the water current in the horizontal position in the idle position . The power plant of this invention can be of various dimensions and does not require a large depth of river that is sufficient to plunge blades. In a river or stream section, several power plants may operate according to width and length. The cut funnel-shaped hood directs the flow of flowing water from the upper blades to the lower blades, which makes it possible to better utilize the current of the current and to concentrate the power on the flowing current. As the enclosure obstructs the front blades from the current, it facilitates the blade descent from idling to the working position and is blocked by the action of the water current in the horizontal position in the idle position. This reduction of resistance increases the torque of the turbine.

The shoulder blades are arc-shaped, with a radius close to the radius of the star, and the transmission elements are chains on which the blades are mounted at a pitch of 0.7 - 0.8 blade height. Then the blades receive the current flowing in the working position to the maximum and stick to each other as fish scales in the idle direction, reducing water resistance. In addition, the blades have holes that allow a portion of the water flow to pass without resistance and encounter the next blade, thereby loading all blades uniformly and reducing their total weight. The hingedly fixed rollers on the blade surface interact with the guides attached to the housing above the conveyor idle bushing and below the conveyor working branch. This allows the blades to rotate freely. When the blades are in the lower working position, they come into the guides and thus ensure the blades' vertical and stability, reduce friction due to the effects of water flow and glow due to the effect of alternating current. When the blades move to the idle position, they move smoothly to a horizontal position. 4 The power plant has a depth tracking device to adjust the amount of water in the hollow chambers. This allows the power plant housing to be maintained at the desired depth. Therefore, the power plant can be immersed deeper in the ice during the winter and avoid the frostbite effects.

The enclosure enclosure is equipped with additional hollow chambers that enhance the stability of the casing.

Water traps are provided on the sides of the housing, and the hood has water flow guides. The current traps and routers additionally direct the flow of water to the lower blades, increasing the torque of the turbine.

The anchors consist of anchors attached to the power plant housing and hood, which allow the angle of the water jet attack to be changed to 35 ° in relation to the power plant and to maintain the power plant at a certain depth. Changing the angle of the water current attack allows you to regulate the power of the power plant depending on the variation of the water flow rate, for example, in spring and summer, and ensures a better utilization of the entire water flow, with equal load on all blades. In addition, it allows you to load all blades uniformly, reduce blade height and increase speed. Due to the construction of the catamaran of the power plant, the flowing water raises the blades which return to the idle position, where the component of the lifting force is formed.

The turbine can be connected through couplings and planetary reducers with a pump and / or compressor and / or an electric generator and / or mechanical drive. This extends the use of the power plant.

The generator can be mounted above the water surface on the rods and connected to the turbine drive via a chain drive mounted on the conveyor shaft. The invention is schematically illustrated in the drawings, in which:

FIG. Figure 1 shows a mobile running water power plant from the side.

FIG. 2-water power plant from the top.

Fig. 3 - Water power plant according to section A-A.

FIG. 4 - water power plant according to section B-B

FIG. 5-FIG. View of part 2 of the circuit C. The power plant has a catamaran-shaped housing 1, which is equipped with an underwater conveyor active turbine consisting of two parallel 5 shafts 2 and 3, on which the star 4 and 5 are attached, connected by circuits having an idle branch 6 and running strokes 7. The chains are fitted with rigid blades in 8 steps, which make 0.7 - 0.8 blade height. The rolls 8 on the surface of the blades 8 are hingedly engaged, which interact with the lower guides 10 and 11. Blades 8 are arc-shaped, having a radius close to the radius of star 4 and 5 and having holes 12.

On the shafts 2 and 3, the couplings 13 and the planetary reducers 14 are fitted with assemblies: shaft 2 - pump 15 and compressor 16, electric generator 17 on shaft 3 and mechanical drive 18.

The casing 1, which has an angle of attack of up to 35 ° with respect to the water stream, is provided with a cut-out funnel 19 having a surface 20 disposed away from the housing at a distance of 1 allowing the blades 8 to rotate. The height of the hood 19 is selected to obstruct the action of the water flow blades 8 when they are in a horizontal position in the idle direction 6. The buoys 21 with hollow chambers 22 are housed in the housing 1 and the housing 19. The casing 1 has lateral currents 23, the water 19 has water currents Guides 24. Locations 25 in Housing 1 and Enclosure 19 Attach anchors 26. Housing 1 depth tracking device 27 is designed to regulate the amount of water in hollow chambers 22.

According to another variant of the power plant, the generator 28 is mounted above the water surface on the rods 29 and 30 and coupled to the mechanical drive via the chain drive 31.

The mobile flowing water power plant works as described below. The power plant is fed into the running water and anchored. The current flowing is pushing the blades 8 of the working stroke of the circuits, which move the stars 4 fixed on the shaft 3, and the stars 5, which are fixed on the shaft 2. The torque is obtained through the sleeves 13 and the planetary (e.g., three-stage 3Kbea) gearbox 14, Increasing the number of revolutions can turn one of the units-pump 15 or the compressor 16 or the generator 17 or the mechanical drive 18.

The cut-out funnel 19 focuses and directs the water stream to the lower blades 8. The required size spacing between the housing 1 and the housing 19 allows the rotating blades 8 to face unhindered downwardly in the lower position. The enclosure 19, when properly heightened, obstructs the upper blades 8 of the water current until they reach a horizontal position.

When the blades 8 find their way into the 7th position (bottom) of the fork, the rollers 9 on the blade surfaces support them in a vertical position to fully receive the water stream. However, when the blades 8 are positioned at the top (top) position of the idle bush 6, they clamp horizontally. Since the blade 8 is an arc shaped, whose radius is close to the radius of the star, it overflows the water stream so that it does not slip down and reduces the resistance when the blade 8 emerges from the water and takes a horizontal position.

The water traps 23 and the guides 24 additionally use a water stream flowing through the sides of the enclosure 19. The hollow chamber 22 in the housing 1 and the shell 19 makes it easier for the power plant to be maintained in the water at the required depth, which is particularly important in winter, and mobile to the desired location. The depth tracking system 27 supporting a certain amount of water in the hollow chambers 22, and the anchors 26, allows the angle of the water current to attack the power plant to be changed to 35 ° and to maintain the power plant at a certain depth.
