Description

II

Изобретение откоситс  к сооружени м защищенного грунта.The invention tends toward the construction of a protected ground.

Известна рама дл  теплиц и парников,Known frame for greenhouses and greenhouses,

включающа  светопроницаемое покрытие иincluding a transparent coating and

.привод с автоматическим проветриванием. Drive with automatic airing

и поддержанием заданной температуры вand maintaining the set temperature in

теплице или парнике 1.greenhouse or greenhouse 1.

Недостатком известной конструкции  вл етс  мала  эксплуатационна  надежность.A disadvantage of the known construction is low operational reliability.

Цель изобретени  - повышение эксплуатационной надежности рамы за счет увеличени  крут щего момента, уменьшени  габаритов и снижени  веса привода, уменьшени  расхода рабочей жидкости.The purpose of the invention is to increase the operational reliability of the frame by increasing the torque, reducing the dimensions and reducing the weight of the drive, reducing the flow rate of the working fluid.

На фиг. I показан парник с поворотной рамой и ее приводом, поперечный разрез; на фиг. 2 - привод-гидроцилиндр, осевой разрез.FIG. I shows a greenhouse with a swing frame and its drive, a cross-section; in fig. 2 - drive-cylinder, axial section.

Каркас 1 и рама 2 покрыты светопрозрачным матерналом. Посредине рамы креп тс  оси 3, сопр женные с отверсти ми в кронш-гейнах 4, закрепленных на столбиках 5.The frame 1 and the frame 2 are covered with a transparent material. In the middle of the frame, axis 3 is fastened, conjugated with holes in bracket 4, attached to posts 5.

К раме 2 н кронштейну 6 на столбике 5 шарнирно крепитс  гидроцнлиндр, содержащий корпус 7, шток-поршень 8 и герметичную снльфонную оболочку 9. В нижней части поршн  выполнено цилиндрическое отверстие , в котором установлен поршень 10 со штоком } 1, жестко соединенный с корпусом 7, и крышка 12 - гидравлический демпфер Гндроцилиндр примерно на высоту корпуса 7 заполн етс  жидкостью 13, имеющей температуру кипени  при нормальном давЛенин ниже 0°С.A hydraulic cylinder is hinged to the frame 2 on the bracket 6 on the column 5; and the cover 12 - hydraulic damper Hydrocylinder approximately to the height of the housing 7 is filled with liquid 13 having a boiling point at a normal pressure of Leninin below 0 ° C.

На раме 2 установлен противовес 14, его вес и усилие гндроцнлнндра взаимно уравновешены при температуре оптимальной дл  закрыти  парника { + 5,..., -(-10°С). Сннженне температуры ниже оптимальной приводит к уменьшенню давлени  насыщенных паров жидкости в гндроцидиндре, вследствие чего противовес поворачивает раму 2 и закрывает поршень.On the frame 2, the counterweight 14 is installed, its weight and the force of the solar force are mutually balanced at the optimum temperature for closing the greenhouse {+ 5, ..., - (- 10 ° С). Lowering the temperature below the optimum leads to a decrease in the pressure of saturated vapor of the liquid in the hydrocidine, as a result of which the counterweight rotates the frame 2 and closes the piston.

При повышении температуры в парнике выше оптимальной усилие гидроцилнндра преодолевает вес противовеса 14 и открывает парник.When the temperature in the greenhouse rises above the optimum, the hydrocylindra force overcomes the weight of the counterweight 14 and opens the greenhouse.
