Abstract

An oxygen increasing device power supply controller applicable for the aquaculture comprises an electrical circuit and a contactor, wherein a coil of the contactor is connected with an output end of the electrical circuit; a movable and a static main contacts of the contactor are separately connected with an electromotor and a power supply of the oxygen increasing device, and the electrical circuit generates the timing signal and drives the movable and the static main contacts of the contactor to turn on or turn off the power supply of the oxygen increasing device electromotor, thereby realizing that the utility model can automatically control the oxygen increasing device to operate, and reducing the manpower burden of the aquaculture farmer.

Description

The aerator power-supply controller of electric

The utility model relates to a kind of oxygen increasing machine for aquiculture control device, especially aerator power-supply controller of electric.

Agricultural is based on the smallholder at present, not only planted but also cultured diverse forms of management, it is in full flourish that culture in the fish pond, does business with little capital and fail on a large scale, fails scientific high investment, get on the job with indigenous methods by experience, drop into by muscle power, eyes are round-the-clock watches the fish pond situation attentively, and both hands are held the power switch of aerator, arduous tired, there is carelessness pond fish hypoxia death to cause economic loss slightly.The smallholder is badly in need of easy use, easily maintenance, the economical and practical aerator control appliance that can alleviate the manpower burden.

The purpose of this utility model provides a kind of aerator power-supply controller of electric, and it can control aerator operation oxygenation or stop in manual or automatic mode, and controller architecture is simple, easily uses, and easily maintenance is economical and practical.

The purpose of this utility model is achieved in that a kind of aerator power-supply controller of electric, form by interior electronic circuit and contactor by timing circuit, the coil of contactor is connected with the output of electronic circuit, and the dynamic and static main contact of contactor is connected with electromotor, the power supply of aerator respectively.The output of electronic circuit can be that the output of triode also can be the contact output of relay, timing circuit produces high level or the driving triode conducting of low level timing signal or ends or drive the dynamic and static contact closure or the disconnection of relay, thereby it is closed or disconnect to make contactor coil get dynamic and static main contact that electric through-flow or outage makes contactor, realizes the aerator motor connecting power and moves or stop.It is out of service again that timing circuit automatically produces periodically variable high level, low level timing signal control aerator operation oxygenation makes dissolved oxygen in water concentration bring up to desired value, when being reduced to certain scope, dissolved oxygen in water concentration moves oxygenation again, this controller automatically replaces peasant household's operation aerator to work rightly, make dissolved oxygen in water concentration remain on a suitable scope, both be beneficial to the fish volume increase and also be beneficial to the saving electricity charge.That the modern integrated circuits technology provides is simple in structure, good stability, timing circuit element that reliability is high, makes electronic circuit so that this controller architecture is simple, easily uses durablely, easily maintains economical and practical.

Owing to adopt such scheme, this aerator power-supply controller of electric can make dissolved oxygen in water concentration keep suitable scope to be beneficial to the fish volume increase and also be beneficial to the saving electricity charge with manual or automated manner control aerator operation oxygenation or out of service.The use simple in structure, durable, easy of this aerator power-supply controller of electric, easily maintenance, economical and practical.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is first embodiment electrical schematic diagram.

Fig. 2 is the timing signal schematic diagram.

Fig. 3 is second embodiment electrical schematic diagram.

Among Fig. 1, a kind of aerator power-supply controller of electric, there are the electronic circuit of timing circuit (T) and contactor (KM) to form by interior, the coil of contactor (KM) is connected with the output (J1) of electronic circuit, the dynamic and static main contact of contactor (KM) (KM1, KM2) is connected with electromotor (M), the power supply (L1, L2, L3) of aerator respectively.The output of electronic circuit is the output (～) of solid-state relay (J1), is the form of triode output.K switch ₁When off state, timing circuit (T) does not produce timing signal, and electronic circuit output (J1) is in off state.Contactor coil is in off-position, and the dynamic and static main contact of contactor is in the disjunction state, and the aerator electromotor is in the outage halted state.Closing Switch K1, timing circuit produces high level, low level timing signal, referring to Fig. 2, during time T 1-T2 timing signal be high level driving solid relay (J1) make the electronic circuit output in the coil of conducting contactor thereby the electric through-flow dynamic and static main contact (KM1 that makes, KM2) closure, aerator electromotor (M) is connected power supply (L1, L2, L3) and starting operation, dissolved oxygen in water concentration improves.Timing signal is a low level during T2-T3, the electronic circuit output is in off state, the coil blackout of contactor makes dynamic and static main contact disjunction, aerator electromotor outage and out of service, timing circuit produced the high level signal driving solid relay again when dissolved oxygen in water concentration slowly was reduced to certain scope, timing circuit automatically circulates and produces high level, low level ... timing signal, aerator operation oxygenation, out of service, operation oxygenation ... make dissolved oxygen in water concentration maintain a suitable scope.

As control signal, high level, the digital circuit structure of low level working method is simple, good stability, the reliability height, conversion pin connection or change component parameters just can obtain different timing signals simply, adopt simple change-over switch K2 conversion gear just can obtain different timing signals, make things convenient for peasant household to use also durable easy maintenance.K switch 3 is to establish for manually controlling, and the K3 closure is aerator operation oxygenation then.

Among Fig. 3, the output of electronic circuit be relay (J2) dynamic and static contact (J21, J22) circuit theory and Fig. 1 with.

This aerator power-supply controller of electric adopts the isolated power transformer transformation rectifying and wave-filtering of high and low pressure to obtain low-tension supply E, and the Electrical Safety requirement is satisfied in the insulation between the high and low pressure, and the simple operations of peasant household is guaranteed Electrical Safety in the electronic circuit of low pressure.

Above-mentioned emphasis is set forth the operation principle of this controller, also can increase breaker according to different instructions for uses in actual the use except fuse FU, and RCCB is selected short circuit, overload, safeguard measure such as under-voltage for use.

Claims

1. aerator power-supply controller of electric, it is characterized in that: form by interior electronic circuit and contactor by timing circuit, the coil of contactor is connected with the output of electronic circuit, and the dynamic and static main contact of contactor is connected with electromotor, the power supply of aerator respectively.
