A device for converting energy of a moving fluid or gas

 

(57) Abstract:

The device is designed to convert the energy of a moving fluid or gas into mechanical energy. The device includes a shaft, blades, energizing flow, with blades fixed at a height of PTO in pairs and singly, symmetrically with respect to its axis of rotation on cantilever beams with rotational degree of freedom about them. Cantilever beams fixed perpendicular to the axis of PTO at distances from each other not less than the height of the blades, the plane of the two pairs of adjacent blades on the height of the output shaft form an angle not equal to zero. Each blade is equipped with a support that holds it in only one half of the stream, separated by a plane passing through the axis of the output shaft and the same direction with the velocity vector of the flow. For the upper pair of blades mounted above the line of their suspension at a distance not exceeding the height of the blades, two additional outriggers, mounted perpendicular to the axis of PTO. This embodiment allows the device to ensure reliability in case of strong turbulence of the working fluid or gas flow. 1, and the/P> It is known device [1] to convert the kinetic energy of water, which has a wheel with a horizontal axis located above the water. The wheel has blades that are alternately perceive the energy of moving water. The disadvantage of these devices is the inability to use it when the temperature is below zero 0oC, the necessity of using a special device for the case of changing the direction of the velocity of the water flow due to turbulence or in the fjord due to the rotation of the tides.

It is known device [2] to convert the energy of flowing water into useful work, in which the removal of power is carried out with a vertical shaft. The energy extraction from water by using a cable with a fixed floating elements made in the form of parachutes with elastic domes. Under the action of water flow elastic dome on one branch - half of the endless rope take the form of domes parachute, and on the other branches - half fold, the result is the force driving the cable, which rotates the pulley of the generator.

This device, besides the above disadvantages bulky, it is easy to zestoreticabdominal wind energy, containing the shaft and the blades, the energizing flow, with blades fixed at a height of PTO in pairs and singly symmetric about its axis of rotation on cantilever beams with rotational degree of freedom about them, cantilever beams fixed perpendicular to the axis of the output shaft at a distance from each other is not less than the height of the blades in the plane of the two pairs of adjacent blades height-shaft, power form an angle not equal to zero, each blade supplied is not rigidly fixed support, retaining it only in one half of the flow divided by the plane passing through the axis of the output shaft and the same direction with the velocity vector of the flow.

The main drawback of this design is that the bearing is able to move, which leads to loss of efficiency when strong gusts of wind, and in the liquid medium under strong turbulent flow. These drawbacks are eliminated due to the fact that the device for converting energy of a moving fluid or gas flow containing the shaft, blades, energizing flow, with blades fixed at a height of PTO popay about them cantilever beams fixed perpendicular to the axis of PTO at distances from each other not less than the height of the blades, the plane of the two pairs of blades, a neighboring height PTO, forms an angle not equal to zero, each blade is provided with a support that holds it in only one half of the stream, separated by a plane passing through the axis of the output shaft and the same direction with the velocity vector of the flow, for the upper pair of blades mounted above the line of their suspension at a distance not exceeding the height of the blades of two additional outriggers, mounted perpendicular to the axis of PTO.

Diagram of the device shown in the drawing, where: 1 - shaft PTO, 2 - bearing 3 - cantilever beam, 4 - blade, 5 - bearing, 6 - additional cantilever beams, 7 - lock.

The device operates as follows. The fluid or gas flow in the direction shown in the drawing, acting on the right of the blade 4, which cannot be deployed around the cantilever beams 3 on which they are suspended, as they rest on the supports 5, creates a torque. Left scapula 4, feeling the pressure of flow, are deployed around their cantilever beams 3, the mi can't keep. Rotor blades 4 are located at the height of the shaft 1 in pairs symmetrically with respect to it, each on its cantilever beam 3, and the distance between the cantilever beams for adjacent pairs of the blades 4 on the height of the shaft 1 should not be less than the height of the blades 4 so that when the shaft 1 none of the blades 4, one pair did not block the energy flow to the blades 4 other couples. The drawing shows two pairs of blades 4, however, for a better use of energy flow, the number of cantilever beams with 3 blades 4 can be increased by altering the angles between the projections of the cantilever beams 3 and corresponding bearings 5 on a plane perpendicular to the axis of the shaft 1. Power is removed from the shaft 1. With a strong turbulent flow, one of the upper blades 4 /left/, after which rotation of the output shaft 1 is not held by the support 5 and slides along the jet stream, can turn around its cantilever beams 3 and disrupt the operation of the device. For this purpose the shaft 1 are mounted two supports that can be made in the form of two additional cantilever beams 6, rigidly fastened to the shaft PTO 1, height above the line of suspension of the first pair of blades 4. These two additional cantilever beams 6 are set by paralamyctes from the coup are the supports (5) suspension of the previous pairs, i.e. for the second pair of blades 4 by the rotation stops are the supports (5) suspension of the first pair of blades 4, for the third pair of blades 4, the rotation stops serve as a support 5 of the second pair of blades 4 and so on 7 - lock, it is not possible to fly the working blades with cantilever beams, the design may be different. The proposed design can use the energy of the flow of gas /wind generators, flow meters/ water in the river, fjord, breaking the waves, marine currents, and when you change the direction of flow of gas or liquid, the direction of rotation of the output shaft is not changed. The design can be fully immersed, to work under the ice, the possible combination of the two systems, surface and underwater, using a combination of the power of water and wind, and transmitting it on a common shaft, for a design flow of liquid or gas that does not fundamentally different.
