Description

Single-phase load round-the-clock program controller

The utility model belongs to apparatus for automatic control.

The cyclelog that is used for field of industrial automatic control at present is varied, the programmable logic controller that has the single-chip microcomputer to constitute; The sequential controller that the band matrix plate is arranged; Also has cam rotary drum sequential controller.Their common issue with is to be suitable for industrial production control, is unsuitable for family expenses and office, and price is more expensive.

It is the single-phase load cyclelog of clock type any programming in diel of power with the motor that the purpose of this utility model is to provide a kind of.

The utility model is by hand switch, alternating current motor, decelerator, shifting block type annular programmable device, with the sensitive switch formation of high-power contact.Alternating current motor one termination power, one end of another termination decelerator, the input of another termination shifting block type annular programmable device of decelerator, sensitive switch one end of the high-power contact of output tape splicing of shifting block type annular programmable device, with the termination load in the two ends in addition of the sensitive switch of high-power contact, one termination hand switch, one end, another termination power of hand switch.

Alternating current motor provides power, drives shifting block type annular programmable device by decelerator, and its speed reducing ratio size reaches the purpose that shifting block type annular programmable device diel is rotated a circle by the number of pole-pairs decision of alternating current motor.Shifting block type annular programmable device is made of dial plate, annular shifting block, axle center.The annular shifting block is positioned at the circumference of dial plate, and the mark of instruction time is arranged on the axle center, and the scale value on the dial plate that its is aimed at is exactly standard time at that time.Shifting block how much be that if 5 minutes be a unit, shifting block is 288 by chronomere's decision of programming Control.20 minutes is that a unit shifting block is 72.Annular shifting block on the dial plate circumference can be changed according to the chronomere of programming Control.The annular shifting block rotates with dial plate and decelerator, and the axle center is motionless.Hand switch of the present utility model is to be used for operating whether high-power contact is controlled by sensitive switch, when hand switch is in the "Yes" position, and programmable device work, load is controlled by it; When hand switch is in the "No" position, the load directly be connected to～the 220V power supply on, not controlled by programmable device.The operation principle of shifting block type annular programmable device is such: 3 explanations in conjunction with the accompanying drawings, hand switch is in the position of "Yes", the controlled bar of sensitive switch is under the control of programming shifting block, and when annular programmable device went to certain position, the programming shifting block contacted with controlled bar; If annular programmable device continues rotation again, the controlled bar of sensitive switch is pushed to the right side, by adjusting screw under the spring leaf effect, the action of instantaneous operation bar makes the closing of contact, when stagger mutually with the top of programming shifting block in top, controlled bar inclined-plane, because the no pressure in controlled bar left side, under the spring leaf effect, controlled bar and instantaneous operation bar are moved to left, the contact disconnects.Under the control of a programming shifting block, the time of the closing of contact is the time that needs programming Control just, and annular programmable device continues rotation, when next one programming shifting block contacts with the controlled bar of sensitive switch, repeat above-mentioned action again, go round and begin again, diel annular programmable device rotates a circle.

Little, in light weight, the low price of cyclelog volume with this structure is suitable for the automatic control of household electrical appliance and office automation equipment most.

Embodiment sees that accompanying drawing 1, alternating current motor are～220V, and power is less than 5W, 750 rev/mins of rotating speeds; The decelerator speed reducing ratio is 1,080,000: 1, and sensitive switch cut-out ability is 3500VA, loads to be～220V, controlled device below the 16A, and annular shifting block is 96, and control time unit is 15 minutes.

Description of drawings: accompanying drawing 1 is a block diagram of the present utility model.1, hand switch, 2, programmable device, 3, alternating current motor, 4, decelerator, 5, shifting block type annular programmable device, 6, with the sensitive switch of high-power contact.
