Description

(54) ДАТЧИК СКОРОСТИ ПЕРЕМЕЩЕНИЯ СНЕГА(54) SNOW SPEED TRANSFER SENSOR

снега укрепл етс  на мачте на некоторой высоте над поверхностью склона. Сползающнй снег, натека  на лопасти винта /, приводит последний во вращение и продолжает свое движение, обтека  корпус. При возникновении перед винтом 1 зоны уплотнени  снега увеличиваетс  давление на винт. Это давление валом 2 передаетс  датчику 8. Возрастание сигнала датчика давлени  вы зывает повышение мощности, подводимой к нагревателю 4. Уплотнение в снегу перед передней кромкой винта разрушаетс  вследствие частичного сплавлени  снега и давление на винт снижаетс .the snow is fixed on the mast at some height above the surface of the slope. The sliding snow, the drift on the propeller blades /, causes the latter to rotate and continues its movement, the streamlined body. When a snow compaction zone occurs in front of screw 1, pressure on the screw increases. This pressure is transmitted by the shaft 2 to the sensor 8. The increase in the pressure sensor signal causes an increase in the power supplied to the heater 4. The seal in the snow in front of the front edge of the screw collapses due to partial melting of the snow and the pressure on the screw decreases.

Сигналы преобразователей 7 и 5 вывод тс  на регистрирующую аппаратуру.The signals from the transducers 7 and 5 are output to the recording equipment.

Кроме данных о скорости сползани  снега косвенным путем по мощности, подводимой к нагревателю, можно судить о плотпости снега.In addition to data on the rate of snow sliding indirectly by the power supplied to the heater, one can judge about the density of snow.
