GUIDING ROAD DEVICE Russian patent published in 2015 - IPC E01F9/12 

FIELD: construction.

SUBSTANCE: guiding road device comprises the truncated cone with dished base designed in the form of the support plate separately with cone. The upper part of the truncated cone is provided with streamlined head. The truncated cone is arranged inside the support plate. Surface of the cone bottom and surface of the support plate bottom which is in contact with it, are designed with spherical outline with convex downward and with different curvature, at that K₁ > K₂, where K₁ - curvature of the spherical surface of the cone bottom; K₂ - curvature of the spherical surface of the support plate bottom, wherein the height of the cone is greater than the diameter of the upper part of support plate, and its centre of gravity is located within the depth of the support plate at $$h=a\cdot \frac{R_2}{R_1},$$ where h - depth of the support plate, cm; a - distance from the point of contact of the spherical surface of the cone bottom with the spherical surface of the support plate bottom to the centre of gravity of the cone, cm; R₁ - radius of curvature of the spherical surface of the cone bottom, cm.; R₂ - radius of curvature of the spherical surface of the bottom of the support plate, cm, besides m₁ ≥ m₂, where m₁ - cone weight, g; m₂ - weight of water displaced by the cone in the volume of the support plate, g.

EFFECT: increase of work reliability of the guiding device by increasing its shear-resistance and resistance to rollover, increase of visual sensitivity.
