Description

Предлагаемое приспособление к вентил тору с электрическим приводом предназначено дл  открывани  и закрывани  крышки выт жной трубы одновременно с замыканием и соответственно размыканием электрической цепи электродвигател  и заключаетс  в том, что пусковой рубильник соединен т гой или тросом с рычажком крышки вентил ционного канала; автоматическое закрывание крышки выт жной трубы одновременно с выключением электродвигател  имеет значение в противопожарном отношении, когда требуетс  как можно быстрее остановить вентил торы и закрыть все выт жные отверсти .The proposed adaptation to an electrically driven fan is intended to open and close the exhaust pipe lid simultaneously with the closing and, accordingly, opening of the electric circuit of the electric motor, and consists of connecting the trigger switch with a lever or cable to the lever of the ventilation duct cover; The automatic closing of the exhaust pipe lid simultaneously with the switching off of the electric motor is important in terms of fire protection, when it is necessary to stop the fans as soon as possible and close all the exhaust holes.

На чертеже фиг. 1 изображает вид сбоку вентил тора с предлагаемым приспособлением; фиг. 2 - схему выключени  электродвигател .In FIG. 1 shows a side view of a fan with a proposed device; FIG. 2 is a motor off circuit.

Обычный электровентил тор 1 помещен в вентил ционной трубе 2, вставленной в стену или окно. Труба 2 снабжена крышкой 3, закрывающейс  на шарнире 4 и прижимающейс  пружиной 5. Крышка 3 снабжена рычажком б, соединенным т гой или тросом 7 с пусковым рубильником 8. Дл  того, чтобы открыть крышку, надо повернуть рубильник 8 по стрелке и вставить в клемму 9. На одной оси с крышкой насажен выключатель от электродвигател  вентил тора . При открывании крышки 3, что составл ет поворот на 90°, выключатель замыкаетс , и вентил тор приводитс  в действие. Когда крышку закрывают , вентил тор выключаетс .A conventional electric fan 1 is placed in a ventilation pipe 2 inserted into a wall or a window. The pipe 2 is provided with a lid 3, closing on the hinge 4 and pressing down the spring 5. The lid 3 is equipped with a lever b connected by a pull or cable 7 with the start switch 8. To open the cover, turn the knife switch 8 in the direction of the arrow and insert it into terminal 9 A switch from the fan motor is mounted on the same axis as the cover. When the cover 3 is opened, which is a 90 ° rotation, the switch closes and the fan is activated. When the lid is closed, the fan turns off.

Схема выключени  показана на фиг. 2, где в изол ционной трубке 10 установлены неподвижные контакты 11, соединенные с проводами 12 и 13 от электродвигател . Внутри на оси насажен проводник 14, который при повороте оси на 90° замыкает контакты.The switch off circuit is shown in FIG. 2, where fixed contacts 11 are installed in the insulating tube 10 and connected to wires 12 and 13 from the electric motor. Inside the conductor 14 is mounted on the axis, which closes the contacts when the axis rotates by 90 °.

Предмет изобретени .The subject matter of the invention.

Приспособление к вентил тору с электрическим приводом, предназначенное дл  открывани  и закрывани  крышки выт жной трубы одновременно с замыканием и соответственно размыканием электрической цепи электродвигател , отличающеес  тем, что рычажок б крышки 3 вентил ционного канала 2 т гою или тросом 7 соединен с пусковым рубильником 8.A device for an electrically driven fan for opening and closing the exhaust pipe lid simultaneously with the closing and, accordingly, opening of the electric motor circuit, characterized in that the lever b of the ventilation duct cover 3 or cable 7 is connected to the trigger switch 8.
