Description

Изобретение относитс  к сельскому хоз йству , в частности к устройствам дл  з,адержани  и распределени  снега но полю. Известно устройство дл  снегозадержани , выполненное из стоек, которыми установлены перемычки, образующие совместно со стойками сплошной забор 1. Известно также устройство дл  снегозадержани , включающее по русно расположенные пр моугольные гибкие пластины и стойки 2. Общим недостатком известных устройств  вл етс  образование из снега около самого устройства сугроба и посто нное выдувание снега из сугроба. Целью изобретени   вл етс  обеспечение равномерного распределени  снега по полю и предохраненение его от выдувани . Достигаетс  это закреплением пластин на стойках по их поперечной оси симметрии, причем рассто ние между ними по высоте равно 2-4 высоты пластины, а по ширине 1-4 высоты пластины. На чертеже схематично изображено предлагаемое устройство дл  снегозадержани . Устройство дл  снегозадержани  состоит из стоек 1, на которых по русно установлены гибкие но русные н.частины 2, арнчом рассто ние .между ними по высоте «В равно 2-4 высоты h 1ласт)ны 2, а рассто ние между ними по ширине равно -t высоты h пластины 2. Р д стоек 1, расстав,1енных по но.чю, образует силошную преграду дл  мете.тевого потока. Г1)оцесс снегозадержани  происходит сле .дующи.м образом. При прохождении ветро ,вого потока через преграду в впде расставленных стоек 1 с гибкими пластинами 2 он испытывает различное сопротивление. В результате обтекани  верхнего р да пластин 2 создаетс  общее затишье в пределах ограждаемой зоны и наблюдаетс  отражение снега . За счет пространства над преградой и меж.ау первым и вторым р до.м пластин, где ветровой поток испытывает меньшее сопротивление , происходит спр мление струй в зону затишь , что способствует выравниванию поверхности снежного покрова и уплотнению отложений, задерживаемых нижними част ми устройства. Предлагаемое устройство при минимальных затратах создает услови  дл  равномерного вихреобразовани  и их дробление.The invention relates to agriculture, in particular to devices for s, storage and distribution of snow in a field. A snow retention device is known, made of racks that have jumpers installed, which together with the racks form a continuous fence 1. It is also known to have a snow retention device including run-flat rectangular flexible plates and racks 2. A common drawback of the known devices is the formation of snow near the very snow drift devices and constant snow blowing from a snowdrift. The aim of the invention is to ensure uniform distribution of snow across the field and to prevent it from blowing out. This is achieved by fixing the plates on the racks along their transverse axis of symmetry, and the distance between them in height is 2-4 in the plate height, and in the width 1-4 in the plate height. The drawing schematically shows the proposed device for snow retention. The snow retention device consists of pillars 1, on which flexible but notorious n.particles 2 are installed, the distance between them in height “B equals 2-4 heights h 1pl) us 2, and the distance between them in width equals -t of the height h of the plate 2. A row of racks 1, spaced 1 by foot, forms a silosic barrier for the meta flow. G1) the snow holding process occurs following the way. With the passage of the wind, the flow through the barrier in the vpd spaced racks 1 with flexible plates 2, he experiences different resistance. As a result of wrapping around the upper row of plates 2, a general lull is created within the enclosing zone and snow reflection is observed. Due to the space above the obstacle and between the first and second plates of the m, where the wind flow experiences less resistance, the spraying of the jets into the zone calms down, which helps level the surface of the snow cover and seal the sediments delayed by the lower parts of the device. The proposed device, at minimum cost, creates conditions for uniform vortex formation and their fragmentation.

что способствует плавному снижепию скорости ветра за преградой и обеспечивает равномерное отложение снега около преграды.which contributes to a smooth decrease in wind speed behind the obstacle and ensures uniform snow deposition around the obstacle.
