Description

Snow-protective devices are known, made in the form of shields installed along the protected strip and decoupled in the presence of wind.

The distinctive feature is onisable. The devices consist in the fact that H1NTYs are composed of nz of inclined planes, sabrauyushenh two narrowing channels to form air jets: the bottom, I hear the skeg, and BepxHeii, 11dsc | 1e to the sedimentation; n; e snow.

This is vile 1E1 11e siegoz; 1SCH gnogo device 1; reducer cd; from deposition of snow on 3aiJiiiHi, strip n provides sd vappe already deposited snow.

As varnapts, uuiTbi can be made with one upper or one single channel.

A snowgate is provided either by blowing snow along the bottom i; the incline overhang above the ground, or by transporting snow over through the snow-snowing device.

The smaller snow blower is based on compression and wellness of the wind flow, passing under the lower plane of compression. Snow transfer is explained by the property of Snezhinkn, which is about a pack, -: he:; see the plane n receiving an air push from the wind flow from below, gain altitude and lengthen the trajectory of its movement. until the receiving pulse is consumed, after which the usual snowfields occur under the influence of attraction5 (. The diversity of dvnezhei1 5 s: 1 of the baskets is determined by the lifting force, which is equal to the production: 1: -in density at wind speed.

FIG. 1 depicts snow protection; shield with two channels, to, speech section; FIG. 2 is the same as the windward side; ; and FIG. 3- snow protection: a new shield with one upper ciaal, in a sectional view; lf FIG. 4 is the same, view from the windward side; in fig. 5- -snow-1 - 1, UiT with the lower channel, in non-infinity times |; on 'F;;-. oh too

Sld on the windward side; in fig. 7 version of the design of a snowboard iJuiTHoro shield with a broken line with one lower channel.

The shield consists of racks), reinforced by nodkos 2, carrying the frame 5, the service} 1 he noreh onorom for obschivki iloskos a, b, e and f.

Planes a, S, and g form a tapering channel to the outlet 4, an upstream channel for the air flow, warning snow deposition, and a flat e and the surface of the earth form a lower qial for air 11:) the current blown off the snow.

The resulting wind impulse in this construction is achieved by the fact that, due to the flat planes, the wind flow is compressed, and at the ends of the channels the wind speed reaches the maximum limit. A rarefied (windward) ribs b and 7 create a rarefied space. the outlet, which, due to compression, causes a blow to the snowflakes; Osls ;; 1Ц1е, having received an impulse, fly away into space, defended: its surface.

A light-protective device with one upper, tapering; on |: ag., Upward channel 8, formed by planes a and b (fig. 3 n 4), forms the upper air flow and prevents the precipitation of snow. Structurally, the shields are made in the same way as the image in FIG. 1 and 2.

C. The siren device can also have one lower channel 9 (Fig. 5-6) formed by the surface of the earth and the shield e, to form an airfoil, an air jet blowing snow,

B; -: The construction of a shield with one lower ciaal (FIG. 7), the upper surface of the channel 10 is formed by a shield of a broken form. In the upper part of the naga there is a visor up against the wind. Then it is at an angle i; this visor is the compression plane l, passing into the vertical .11, and the inclined plane n for the outflow of wind flow, which, together with the ground, represents braysboit, from where the wind flow expires, brought by these planes to the speed limits.

Claims (2)

1. A snow-banging device, made in the form of shields installed along the protected strip, operating in the presence of wind, about and GC tea e so that, in order to prevent snow deposition on the protected strip and deflating already settled on the protected strip snow, the shield is made up of four inclined planes, of which one nlosk forms a lower constricted channel with the ground surface for the lower air jet blowing out of the snow, and the other three planes constitute an upper conical rezhdayuschey snow precipitation, transverse air jet at at otnoscheniya to the enclosing strip towards the wind. 2. The siego-protective device according to claim 1, characterized in that, in (with the help of pylon shields, an upper tapering cap is formed to create an upper, preventable deposition of snow by an air stream. about. Snegozashch.ntny device but n. 1, with the fact that in not:.:, Help of inclined shields, one lower shedding channel is formed for the formation of a lower jet of air blowing off the snow. to oTi r - ti CO - .v.vj.v - I I CD &
