Description

Timer for controlling electricity use

The utility model relates to a kind of timing device, more particularly, is a kind of regularly control electricity consumption timing device of periodic duty such as control illuminating line, electric equipment that is applicable to.

In the prior art, no matter be mechanical timer, or electrodynamic timer, all be by a power source, as clockwork spring wheel assembly or motor,, drive cam rotation through kinematic train, with the state of cam control spring contact, and then the switching of control consumer power supply, make its timing working.There is following weak point in this timer: for once setting, spring contact can only move once, and just, controlled consumer can only be at timing then, the disposable on-off of its power supply.Therefore, this timer is not suitable for the consumer that control need repeat work, as the light fixture of public place.

The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of timing device is provided, and carries out repetitive work at a certain time interval automatically in order to the control consumer.

The purpose of this utility model is achieved through the following technical solutions.

The utility model is to form with quartz clock movement and pilot relay.It is characterized in that the engagement of timing wheel and crystal clock hour wheel.Described timing wheel, its whole wheel disc are that the fan-shaped card space that the nonmetallic materials of the fan-shaped card made by at least one conductive metallic material and at least one insulation are made constitutes.Two terminal wire of control power supply are connected with pilot relay coil one end with the hour wheel post of crystal clock respectively, and the other end of pilot relay coil is connected with the timing wheel post.Described pilot relay contact is serially connected in the electric power loop of controlled consumer.

Normally walk constantly at crystal clock, the rotation of crystal clock hour wheel drives timing wheel and rotates thereupon.When the metallic conduction card engagement that turns to hour wheel and timing wheel contacts, conducting metal card, timing wheel post and relay coil and control power supply by hour wheel post, hour wheel, timing wheel constitute the loop, relay coil gets electric, and move its contact, changes the duty of controlled consumer; When the insulated non-metal card engagement that turns to hour wheel and timing wheel contact, the electric power loop disconnection of relay coil, coil losing electricity, its contact resets, the controlled consumer state of also resuming work immediately.During along with the walking of crystal clock, hour wheel and timing wheel constantly rotate, and the above-mentioned course of work can constantly repeat automatically.

The utility model is compared prior art and is had following advantage.

1, use the utility model can realize that consumer carries out the automatic control of repetitive operation at a certain time interval.

2, adopt crystal clock as timer, the timing accuracy height, error was less than per 24 hours 0.5 second.

3, the utility model is simple in structure, cheap, easy to use, widely applicable.

Fig. 1 is the utility model operation circuit synoptic diagram.

Fig. 2 looks synoptic diagram for the utility model hour wheel and timing wheel positional structure master.

Fig. 3 is the utility model hour wheel and timing wheel positional structure schematic top plan view.

Number in the figure: 1, quartz clock movement, 2, the crystal clock hour wheel, 3, the hour wheel post, 4, timing wheel, 5, the timing wheel post, 6, the quartz clock movement clamping plate.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Referring to accompanying drawing 1, timing device is used for the automatic control of public place illuminating line.The control power supply directly adopts the illuminating line power supply, and two terminal wire of power supply are connected with coil one end of hour wheel post 3 and A.C. contactor J respectively, and the coil other end is connected with timing wheel post 5.The a pair of normally opened contact J1 of A.C. contactor J is serially connected in the electric power loop of illuminating line.

Referring to accompanying drawing 2,3, timing wheel 4 is meshing with each other with crystal clock hour wheel 2, and timing wheel 4 is installed on the quartz clock movement clamping plate 6 with timing wheel post 5.Hour wheel post 3, hour wheel 2 and timing wheel post 5 are conductive metallic material and make, and between hour wheel post 3 and timing wheel post 5 and quartz clock movement clamping plate 6, are respectively arranged with insulation spacer.

For the quartz clock movement that showed in existing 12 hours, the gear ratio that hour wheel 2 and timing wheel 4 are set is 1 to 2, and like this, the duty of illuminating line promptly can 24 hours is the repetition period.The fan-shaped card space that the fan-shaped card that the whole card of timing wheel 4 is made by two conductive metallic materials and two blocks of insulated non-metal materials are made constitutes, illuminating line has in a cycle of 24 hours and illuminates for twice, by two positions of metallic conduction card on timing wheel 4 are set, illuminating line twice in one-period can be illuminated and be arranged in evening and early morning respectively.Change the ratio of each fan-shaped card arc length on timing wheel 4 circumference, can change in the illuminating line one-period twice time interval between illuminating.
