Description

Automatic flow-controlling device for musical fountain

The utility model relates to a kind of music fountain that is used for, the device that spray flow is changed automatically with the sound signal power.

Existing music fountain, its water spray accompanied by music and changing generally is that the rotation speed change by pump realizes.Because the inertia of pump motor, making the water yield change the frequency response that changes for music has tangible hysteresis.In order to remedy this defective, the fountain apparatus that has adopts the method for prefabricated asynchronous vocal cores.But this has not only increased cost of manufacture and complicated property, and the scope of application of music fountain is restricted.

The purpose of this utility model is that a kind of simple and reliable device will be provided, and it can realize the spray flow (or height) of music fountain effectively, changes automatically with sound signal power (or rhythm speed).Not only frequency response is good, and is applicable to all kinds of sources of sound and need not any prefabricated formality.

The purpose of this utility model is achieved in that

Sound signal peak level pick-up circuit, solenoid valve SCR control circuit and flow controller in parallel are connected into an automaton.Sound signal is through the pick-up of sound signal peak level pick-up circuit, and the pulse signal that detects is strong more, and it is many that the light lotus root that is switched in the circuit is closed Guan Yue, and that then ends a little less than the signal is many.By the light lotus root close pipe with sound signal peak level pick-up circuit and solenoid valve SCR control circuit mutually lotus root close.Light lotus root is closed the conducting of pipe or ends, and is directly controlling the silicon controlled conducting of a correspondence or ends.And be subjected to thyristor controlled each solenoid valve in flow controller in parallel, to serve as the switch of each parallel branch.Electric adhesive solenoid valve the more, always supply flow the more.So, the variation of water spray height, just consistent with the variation of the power of sound signal.

The utility model closes owing to adopting the light lotus root to close the pipe lotus root, and existing higher sensitivity has the good isolation effect again.Because adopt each parallel branch of solenoid control, simple in structure, action response is fast, flow is controlled easily, and installation and maintenance are convenient.

The concrete structure of utility model is provided by following example and accompanying drawing thereof.

Fig. 1 is a sound signal peak level pick-up circuit.

Fig. 2 is a solenoid valve SCR control circuit.

Fig. 3 is a flow controller synoptic diagram in parallel.

Describe details and working condition in detail below in conjunction with each figure according to the concrete device that the utility model proposes.

With reference to Fig. 1, sound signal peak level pick-up circuit, its primary structure are five one-stage amplifiers.Be connected in series diode (D3～D6) between each amp.in successively; Make each input voltage keep a difference (being equivalent to the diode forward pressure drop) successively.(G1～G5), phototriode wherein change with collector current and conducting or end to contain the optically-coupled pipe in the collector load.Import the sound signal that coupling is accepted by input transformer B and pressure regulation potentiometer Rw, close and D1, D2, C2 detection, be added on each amplifier input terminal with different stepped-up voltages through the C1 lotus root.Signal input quantity increases gradually by zero, and G1 to G5 is conducting successively.How many light lotus roots of conducting closes pipe, has reacted the power of sound signal.By regulating Rw, can make input signal and each stepped-up voltage be transferred to appropriateness.

With reference to Fig. 2, solenoid valve SCR control circuit, its effect is to accept the signal that the light lotus root is closed pipe, changes according to the power of sound signal, conducting or close corresponding controllable silicon causes corresponding solenoid valve coil (a, b, c, d, e) energising or dead electricity.Adopted typical double-basis utmost point pipe trigger generator in this circuit, characteristics are with output A, B in the front stage circuits (as shown in the figure), C, D, the E input as this circuit, are serially connected with in the charge circuit of oscillator.Five light lotus roots of G1 to G5 are closed pipe, and a conducting is arranged, and the oscillator starting of oscillation of a correspondence is then arranged, the controllable silicon of a correspondence of conducting.Successively the light lotus root of conducting to close pipe many, the controllable silicon that then is switched on is also many, electric solenoid valve is also many.In order to simplify the power of electromagnetic valve circuit, adopt Alternating Current Power Supply, so adopt bidirectional triode thyristor.

With reference to Fig. 3, flow controller in parallel constitutes for the parallel connection of stream branch road by five, and its input end links to each other with sparge pipe with water inlet pipe respectively with output terminal.A solenoid valve of serial connection and a gate valve on every parallel branch.This flow controller in parallel plays direct control aquifer yield at fountain for flowing in the piping system.Be subjected to the solenoid valve (a, b, c, d, e) of ghyristor circuit control to get electric water flowing, dead electricity is closed water.The solenoid valve of opening is many, and then total aquifer yield is big, otherwise then few, and it changes and the power of sound signal changes synchronously.Gate valve L1～L5 can adjust each branch road hydraulic pressure, and the unlatching number that makes the variation of injection flow rate and solenoid valve is near direct ratio, thereby changes near direct ratio with the power of sound signal.
