Description

The invention relates to the conversion of thermal energy into mechanical energy using thermal deformations of solid thermosensitive active elements and can be used to drive various mechanisms and devices.

The aim of the invention is to reduce the size and weight.

FIG. 1 shows the device a general view; in fig. 2 is a view A of FIG. 1 along the axis of the device; in fig. 3 - joint node of the rocker arm with the shaft.

A device for converting thermal energy into mechanical energy comprises a cylindrical body 1 with a window 2 on its side surface for transmitting heat rays and a rotor 3 installed in case 1 with a platform 4 fixed on it and a central axial shaft 5. In the internal space of the body 1 against the screen 2 there is a heating zone 6, and in the shade behind the rotor 3 - zone 7 is cooled. The rotor 3 houses thermally sensitive active elements in the form of orientation along the axis of the rotor 3 of the rods 8, attached by their ends to the platform 4 of the rotor 3 and connected by opposite ends to the pushers 9. The rotor 3 and the housing G are made of a material reflecting heat rays, and active elements 8 - from a material with a large temperature coefficient of linear expansion. The pushers 9 are provided with rollers 10, pressed against the guide surface 11 of the housing 1. The pushers 9 are made in the form of axles 12 and hinges 13 mounted on the shaft 5 with the possibility of swinging in the radial planes of the rocker arms 14. At the opposite ends of the rocker arms 14, the rollers 10 and The rods B are fastened with their ends. An inclined ring 15 is fastened on the housing 1, on which the guide surface 11 is made in the form of an inclined plane.

The device works in the following way.

The heat rays 16, for example, the sun, are directed to the window 2 and heat the rods B, which are in the window zone 2. Under the action of the heat of the rays 16, the active elements B are extended, and the active elements B, which are in the shade behind the rotor 3, are cooled and therefore constricted. During its compression, the rods B tilt the rocker arms 14, which abut against the flat surface 11 and, using the rollers 10, scrape it in the direction of the arrow B (see Fig. 2), rotating the shaft 5 with the rotor 3. This the rotation process is maintained continuously as the subsequent active elements B are moved to the shadow behind the rotor 3.
