UA113052U - WAVE HYDRO POWER PLANT - Google Patents

Abstract

A wave hydropower plant contains hydro wheels that convert the motion of the sea waves into a rotational motion, an electric generator that generates electricity. Hydraulic wheels, such as movable valves, are assembled into garlands floating on the surface of the water and transmit their total torque to the shore generator, and all the garland hydraulics are periodically fixed by anchors to the seafloor through the bearings that allow it to be freely routed. is located on the surface of the water, depending on the direction of motion of the waves in its location.

Description

A useful model belongs to hydroelectric plants, namely hydroelectric plants that use the energy of wave motion.

There are many types of stationary and floating hydro units that can generate electrical energy by converting the energy of wave motion into electrical energy.

For example, in the book "Znergiya voln", Dzvid Ross (Leningrad: Hydrometeoizdat, 1981) there is talk of several types of devices for converting wave energy into mechanical and electrical energy.

This is a floating Kokkerel raft for working in open seas with big waves, duck

Saltera for work in the coastal zone, Masuda oscillating column, etc.

All these devices have their advantages and limitations. Many factors must be taken into account when choosing a particular device. The marine environment is sometimes very aggressive, the energy it carries varies from very high to zero, and all this requires taking into account many factors that depend on the cost of the equipment and its payback.

Recently, both in wind energy and in wave energy, there is a tendency not to go to the complexity of devices in order to increase their efficiency, which leads to an increase in the price of energy and a decrease in its competitiveness, but to use simple devices with lower efficiency, but occupying the largest space. Space itself is a carrier of energy, and it costs nothing. As the inventor of the Salter duck, Stefan Salter, said: "The efficiency of the equipment is of little concern to me, as long as the gods pay for this energy."

The basis of a useful model is the task of increasing efficiency.

The task is solved by the fact that hydrowheels are assembled into garlands that float on the surface of the water, transmitting the total torque to an electric generator located on the shore, and the entire garland of hydrowheels is periodically fixed by anchors to the seabed through bearings that allow it to rotate freely, and is located on water surface depending on the direction of wave motion at its location.

The proposed wave hydroelectric power plant is schematically shown in fig. 1 and Fig. 2: - 1- the supporting shaft of the hydrowheel, which floats on the surface of the water and can rotate under the influence of waves; -2 - hydraulic wheel blades, for example, in the form of non-return valves; - C - cardan connection of hydrowheels among themselves; - 4 - BEARINGS; - 5 - tension cables; - 6 - anchors or weights that fix the entire garland; - 7 -- an electric generator located on the shore.

The operation of the wave hydroelectric power station is obvious from the drawings and does not require special explanations. The whole garland, which floats on the surface of the sea, is towed by a small boat to the place of installation and fixed by a system of tension cables 5 to anchors or sunken to the bottom, for example, concrete blocks 6.

Cables 5 are attached to bearings 4 and allow each supporting shaft of the hydrowheel 1 and the entire garland to rotate under the influence of waves, transmitting the averaged total torque to the electric generator 7 located on the shore.

The entire garland works like a hinged breakwater, receiving the flow of wave energy and converting it into rotational motion. The requirements for gimbal connections are small here and strong metal rings can work as gimbals. Given the small angle that occurs at each connection, the loss of motion transmission will be insignificant.

Taking into account the fact that there are no electrical devices or complex units in the sea, the reliability of the wave hydroelectric power plant can be quite high. Oversized waves will simply roll over the waterwheels without damaging them, as can be seen in Figure 2.

Based on the fact that the number of hydrowheels in one garland can be significant, and the number of garlands located in a specific bay is limited only by its size, it can be assumed that the proposed wave hydroelectric power station will collect and convert a large part of the wave energy into electricity.

Taking into account the fact that this result is achieved without large capital hydro-structures by simple means, but with coverage of a large surface of the sea, we hope that our wave hydroelectric power plant will be able to make a significant contribution to obtaining free renewable energy of sea waves, sea energy.
