Definitions

  • the invention relates to energy.
  • a screw turbine can be used to convert the kinetic energy of a moving fluid or gas into mechanical or electrical energy.
  • a screw-turoin consisting of supplied with blades.
  • Parts are mounted on an axis parallel to the direction fluid or gas movements.
  • the first part is fixed motionless on the axis, the remaining parts are mounted on the axis with the possibility of rotation within the limits determined by the limiters mounted on adjacent parts, the last part is connected to the axis by a spring mechanism.
  • Adjacent parts can be connected by spring mechanisms.
  • each item, movable relative to the axis it may be coupled with the axis of the spring mechanism.
  • Limiters can be made in the form of a spike and groove or in the form of a shock absorber.
  • FIG. 1 parts B, C, D (Fig. 2, 3, 4) are mounted on the axis 1 with the possibility of rotation. All parts are equipped with limiters (rotation), which are made in the form of a spike 2 and a groove 3 on adjacent parts (on the first part, a groove 3 may be absent, in Fig. 1, part A is made without groove 3), so that the spike 2 of part A is aligned with a slot 3 of part B 5, in this case, in the extreme position of the tenon in the groove, the blades of part B are aligned with the blades of part A, and further, the blades of part C with the blades of part B and the blades of part D with the blades of part C.
  • limiters rotation
  • the limiters can be made in the form of shock absorbers 5 (Fig. 9-11) mounted on adjacent parts.
  • the spring mechanism 4 can be made in the form of a spiral spring (Fig. 4), fixed on the axis 1 and on the last part D.
  • the spring mechanism 4 (hereinafter, the spring 4) creates tension so that the blades of all parts in the absence of flow or low flow liquid or gas were completely straightened.
  • Each of the parts moving relative to axis 1 (B 5 C, D) can be connected by a spring 4 to the axis. Adjacent parts can be spring-loaded
  • the screw turbine operates as follows.
  • the blades When folded, the blades are supported by each other and have a smaller working area, which provides increased strength. When weakening the air flow, the spring 4 will open the blades in the reverse order. In this embodiment of the screw-turbine, only slight fluctuations of the blades are possible at the moment when the flow force begins to fold the blades and the spike 2 is not in the extreme positions of the groove 3.
  • shock absorbers 5 can be used (Fig. 9-12), which are attached to adjacent parts and in extreme positions provide the addition of the blades or the full opening of the screw-turbine, moreover, the folding takes place without hindrance, and the opening with resistance (slow).
  • FIG. 4 shows an example of a screw-turbine with eight blades from four 2-blade parts, however, there can be a different number of parts with blades and the blades themselves, depending on the feasibility.
  • the pair of stud-grooves on each next part is made with the possibility of rotation by the required angle relative to the previous part (in the example presented, this angle is 45.
  • the connection of each part (except the first part A) with springs 4 of different elasticity with axis 1 or with adjacent parts allows you to control the addition of blades of different parts with a certain wind force, which simplifies the process of adjusting the installation.
  • a screw turbine when used in wind energy will help increase wind turbines. Given that usually the wind speed is 5-10, the wind turbine reaches its maximum energy output at 15 m / s, then the generation of electricity by a wind farm can increase several times.

Abstract

L'invention concerne le génie énergétique. La vis et turbine peut s'utiliser pour transformer l'énergie cinétique d'un gaz ou liquide en mouvement en énergie mécanique ou électrique. L'invention vise à augmenter le coefficient d'utilisation de l'énergie s'écoulant à une vitesse variable et à réduire la résistance au flux à des charges élevées. Selon l'invention, la vis et turbine est constituée de pièces à ailettes montées sur un axe parallèle à la direction d'écoulement du liquide ou du gaz. La première pièce à ailettes est montée fixe sur l'axe et les autres pièces à ailettes sont montées sur l'axe de manière à pouvoir pivoter dans les limites déterminées par des limitateurs montés sur des pièces connexes avec des pales, la dernière pièce à pales étant reliée à l'axe par un mécanisme à ressort. Les limitateurs se présentent comme un tenon et logement ou comme des amortisseurs. Les pièces à pales connexes peuvent être reliées par des mécanismes à ressorts. En outre, chaque pièce à pales peut être reliée à l'axe par un mécanisme à ressort.
