(57) Abstract:Usage: the invention relates to hydropower for elektrowerke in the conditions of the glacier. The inventive installation for the energy of the stream of ice-like base 1 connects both slope 2 of the canyon, and the U-shaped frame 4 with its crossbar 7 with the toothed wheel 8 is directed away from the hinge connections 5 in the direction of ice movement, and the crossbar 7, supplemented spoonlike body 6, is bonded flanges with the side walls of the frame 4 and bearing the multiplier 9, which connects the wheel 8 with the generator. In the bottom of the casing 6 is provided by the slot F, through which the wheel 8 segment protrudes outside of the bottom shell plating 6 on the ice surface, and the pole of maximal curvature of the bottom chassis 6 is displaced in the direction of the hinge connections 5 of the frame 4 with the frame 1. Wheel 8 teeth of the lower segment, udaliaias in the surface of the glacier slowly rotates and through the multiplier 9 actuates a generator. The bottom of the casing 6 with his pole and grooves located on the bottom of the casing between this pole, the hinge connections 5 and the side walls of the frame 4, clears and smoothes the path behind the wheel 8. 1 C. p. F.-ly, 2 Il. Izobretatelnym for the energy of the latter.Known installation for testing energy of the flow of ice containing the power unit, which includes the U-shaped frame carrying at its axial crossbar gear and the multiplexer generator at the ends of both sides of this frame pivotally connected with the frame and axle gears the crossbar of the U-shaped frame mounted horizontally with the possibility of interaction of the wheel with the surface of the moving ice stream, and a gear wheel is in mesh with the input gear multiplier nudedomai surface.The disadvantage of this setup is the formation before it hummocks of ice, which increases the pressure and decreases the reliability of the installation.The purpose of the invention is to enhance reliability of operation of the installation for the energy of the flow of ice.This goal is achieved by the fact that the bed is made bridge type, with the possibility of installation on the glacial slopes of the canyon, and the crossbar of the U-frame is offset from its hinges, connecting it with the frame, in the direction of the ice flow, and the crossbar is made with a spoonlike body with a convex bottom, facing down, polozani on this spoonlike body, which in terms of symmetrical relative to the plane of rotation of the gears, and in the bottom of the body is cut, forming a window for segment free of protrusion of the gear wheel under the bottom spoonlike body.In addition, the pole of maximal curvature of the bottom spoonlike body offset from the axis of rotation of the toothed wheel in the direction of the hinge connections of the U-frame bridge-type bed, and in the area of the external surface of the casing bottom spoonlike body, located between the said pole of curvature of the bottom and the hinge connections of the U-shaped frame bridge-type bed, and between the sides of this frame are made pointed cross rifle.In Fig. 1 shows an installation for energy use ice flow cross section; Fig. 2 - the same, lateral view.The apparatus comprises a frame-like 1 and a power node. Column 1 connects both slope 2 (Fig. 1) canyon filled glycerol mass 3. The power unit includes a U-shaped frame 4, coupled with the frame hinge connections 5, spoonlike body 6 attached to the side walls of the frame 4 from the bottom at the location of the frame of the axial crossbars 7, the toothed wheel 8 is Thor and the crossbar 7 is located on the housing 6.The crossbar 7 is the axis of the gear wheel 8, which is engaged with the input gear 10 multiplier (Fig. 2). Pole L of maximal curvature of the bottom spoonlike body 6 is displaced relative to the axis of rotation of the gear wheel 8 in the direction of the hinge connections 5. At the bottom is provided by the slot R. Through her wheel segment 8 and freely (with a circular gap) protrudes outside of the bottom plating to the ice surface B.On the section of the external surface of the casing bottom casing 6, between the pole L and hinge connections 5 of the frame 4, with the frame provided by the transverse rifle F. They are located across the flow glycerol mass 3. The amount rifle f have the form of chevrons, facing the top corner to the side of the hinges 5. Bridge-take 11 carries a lifting device 12, towering above the extremity of the body and over the toothed wheel 8 and the input gear 10 multiplier 9.The device operates as follows. Ice mass 3, continuously moving along the bottom of the canyon, limited coastal slopes 2 (Fig. 1), involves the rotation of the gear wheel 8, which is under the gravitational load of the main part of the energy of the node.When this happens prastatoy. In order that the rotation was continuous, the hinge connection 5 allow the rotor to track vertically all surface mini roughness of the glacier along the path of the teeth of the lower segment of the wheel 8.If the wheel 8 is found snow cover and surface roughness of the ice increases, the same hinge connection enable convex bottom of the case 6 to come in contact with the glacier. In this case, the pole L not only pushes the snow on both sides of the housing 6, but also smoothes the path under the cog wheel 8.Snow is not stuffed in the gaps P between the ends of the toothed wheels 8 and the walls of the slot in the bottom of the case 6. If irregularities glycerol surface in the vertical direction start to exceed the height of the teeth of the gear 8, the ice ledges are cutoff by riffles F. When this herringbone arrangement of these riffles will allow time to move the ice shavings on the sides of the track.Transmission installation thus protected from significant dynamic loads. As for transverse cracks, the ones that width is much smaller than the radius of the wheel 8, do not cause interruptions in elektrowerke. If the crack is too large, then the failure of the gear coochey rook, which covers a wide crack. Wheel 8 "steps" crack, interrupted elektrodynamika resumes automatically.In that case, when the power unit is to be output from steps (e.g., for repair) using lifting device 12 to lift the wheel 8 on the glacier for a toe housing 6.
