Description

Pontoon Water Power Plant
Field of Application
The invention involves a pontoon water electric power plant to be applied in the production of hydroelectricity through the transformation of the kinetic energy of running water.
Previous State of the Art
Flow-driven hydroelectric plants have been known in the past, combining accelerating devises (confuser-difrusers) and various types of water wheels and turbine energy transformers. Non-turbine energy transformers are in principle simpler and easier to manufacture and exploit. These devices do not involve any acceleration of a freely flowing fluid. This, however, is a limitation to their application as at low velocities of the flow the efficiency of the plant is also low and the electricity generators produce lower power (1).
Technical Description of the Invention
The purpose of the invention is to provide a pontoon hydroelectric power plant that combines the advantages of the non-turbine methods of transformation of the kinetic energy of river flow, sea or ocean streams and the highly efficient solutions for power generation based on helicoidal fluid dynamics. To that end, the invention combines hydrodynamics and draft-related principles for energy removal from water current and the transformation thereof into electric power.
This task is addressed by a pontoon power plant, consisting of two principal components: accelerating system and power retrieval unit. Based on the Bernoulli principle, the accelerating system increases the velocity of the natural current of the water using confuser-diffuser and whirl-generators. It's section is smaller than the section at the confuser intake and this causes a corresponding increase of the velocity of the water current as compared to the velocity thereof before the accelerating system, whirl-generators multiply the acceleration caused by the application of the Bernoulli principle.
Flowing through the work channel, the water current propels several blade groups mounted on synchronous belt or roller chain transmission systems that turn the linear motion of the current into rotary motion, chain/belt systems transfer the motion to two groups of sprocket wheels or pulleys fixed on horizontal shafts. These shafts, in turn, set in motion a corresponding number of electric power generators. The blade groups of each transmission system are mounted at an angle of less than 45° to the vector of the velocity of the current in the work channel. Each of the blade groups is divided length-wise into two sub-groups, attached at reverse angles to the central axis of the work channel herringbone pattern. Each blade group is a mirror image of the previous one. Working are the blade groups dipped into the water. The angle of the blades to the vector of the current velocity creates pressure on them that is transmitted to the flexible chain/belt transmissions and, in turn, to the sprockets or pulleys. The rotary motion thus transmitted to the two shafts of the transmission system is transferred to a number of electric power generators. Depending on the velocity of the current in the work channel and the square area of the blades, various parameters of the angular momentum and the angular velocity are possible. The advantages of the invention include independence of seasonal or other tide- related fluctuations of the water level. No investments in land are necessary and various earthquake, flood etc. risks are reduced to a minimum. It is possible to move the power station to specific consumers as well as increase the productivity thereof by additional modules. The water is reusable and its quality and power producing properties remain intact. The angle velocity at the shafts of the transmission systems allows for the use of a high rpm power generators of better weight/power ratio than the traditionally used in hydroelectric plants low rpm generators.
Explanation of the drawings
A model implementation of the plant is shown on the drawings attached as follows: Fig. 1. Principle design of the power plant; Fig. 2. Side view of the power plant;
Fig. 3. Design of the transmission system - view from above, showing two blade- groups; Fig. 4. Design of the transmission system A-A.
Optional implementation of the invention
The pontoon hydroelectric power plant as per the invention contains shielding device 1, to protect the confuser 5 and pontoon 3 from drifting solid bodies. To the pontoon 3 confuser 5 and diffuser 7 are attached and linked by work channel 6. In the confuser 5 and diffuser 7, whirl-generators 8 are mounted. The power transmission systems 4 are mounted along the work channel 6 of the pontoon 3 and their shafts 16 transmit the motion from the water current to the power generators 9. On the shafts 16 of the transmission systems are fixed large sprockets/pulleys 12 and small sprockets/pulleys 13, which rotate long chains/belts 14 and short chains/pulleys 15 respectively. On long crosspieces 19 and short crosspieces 20, mounted on the long and the short chains/belts respectively 15, the separate blade groups 18 are mounted. Each blade 21, of a blade group 18 is mounted at an angle of less than 45 °to the axis of the work channel. The pontoon is fixed to the bottom of the water basin by anchors 2. The pontoon 3 is also the foundation for the equipment room 10 of the hydroelectric power plant. The electricity produced is transmitted to the grid by cable 11 from the pontoon to the river bank. The pontoon hydroelectric power plant functions as follows:
Having been accelerated through the confuser 5 and whirl-generators 8, the water current is directed into the work channel 6, where it exerts pressure on the blades 21 of the blade groups 18, which are consecutively dipped into the work channel 6. Through the long crosspieces 19 and the short crosspieces 20, the pressure on the blades 21 is transmitted to the long chains/belts 14 and the short chains/belts 15, and further on, to the large sprockets/pulleys 12 and the small sprockets/pulleys 13. As the big and the small sprockets/pulleys are fixed to the shafts 16 of the transmission system, the rotation is transferred to these and to the power generators 9 respectively. All transmission systems 4 mounted along the work channel 6 are driven likewise.
