Description
Technical field
The utility model relates to a kind of water plug, is specifically related to a kind of tongue tube control automatic water pumping device for water.
Background technology
At present, vast rural resident ' s family digs well at the home of oneself, build water tower at building top, utilize water pump that the water of well is extracted into water tower and solve the problem of water consumption of oneself, still, draw water is at present with manual operation, and be all the elderly and children operation, between twenty and fifty people manuals labour of going down town, operates dangerous (easily electric shock) like this, also often forget and close electricity, cause the waste of water resource loss and electric energy.
Summary of the invention
The purpose of this utility model is to provide a kind of tongue tube control automatic water pumping device for water, and it is easy for installation, use simply, better solved manual operation to people live the inconvenience brought, be the good a kind of automaton of household water tower.
Technical solution of the present utility model is:
A kind of tongue tube control automatic water pumping device for water, comprises the motor of the use of drawing water, working power and power supply indication, and its special character is: also comprise the high/low water level tongue tube that is arranged in water tower, float with hole circular permanent magnet; Relatively delay circuit, the first transistor amplifier, the first electromagnetic relay, the second electromagnetic relay and motor are connected described high water stage tongue tube with first successively; Relatively delay circuit, the second transistor amplifier, electromagnetic relay 2 and motor are connected described low-water level tongue tube with second successively; Described the first comparison delay circuit/the second relatively delay circuit adopts respectively resistance and capacitor bank.
Above-mentioned the first electromagnetic relay adopts direct-current working volts 12V single contact miniature relay, and described the second electromagnetic relay adopts the relay of direct-current working volts 12V double-contact, contact capacity 20A.
Above-mentioned the first/the second transistor amplifier adopts respectively the compound composition of triode of two PNP and NPN polarity.
Above-mentioned working power adopts high-low pressure to separate coiling, and power >=3W, forms stable 12V working power by tetra-diode rectifications of 1N4002, the filtering of 1000U F25V electrochemical capacitor, 7812 three terminal regulator voltage stabilizings at transformer that secondary voltage is 15V.
Above-mentioned power supply indication comprises the power work indication of red light emitting diodes and the work of the drawing water indication of green LED.
The utility model is easy for installation, use simply, better solved manual operation to people live the inconvenience brought, be the good a kind of automaton of household water tower; Motor switch is reasonable, has solved or has closed down too early, and causing the water pump frequent starting phenomenon of drawing water is water pump reduction of service life, or closing down late water overflows from water tower, causes water resource to run off and the technical matters of waste of energy.
Embodiment
Principle of work: 220V civil power is system power supply through transformer transformation, rectifying and wave-filtering.Red light emitting diodes is stand-by operation indication, green LED is the work indication of drawing water, when water tower level approaches low-water level tongue tube, float with hole circular permanent magnet near low-water level tongue tube, low-water level tongue tube is worked to the second transistor amplifier through the second comparison delay circuit by the information of magneticaction closure, make the second electromagnetic relay double-contact Chang Kaiduan closure, one contact is that motor power supply starts to draw water, another contact joins by normal-closed end and the power supply of the first electromagnetic relay, form with the second electromagnetic relay and produce self-locking, (avoid water tower level rising low-water level tongue tube contact water, the second triode amplifier is not worked and is made the second electromagnetic relay lose the impact of voltage motor power-off).In the time that water tower level rises to high water stage tongue tube, float approaches high water stage tongue tube with hole circular permanent magnet, high water stage tongue tube is worked through the first comparison delay circuit, the first transistor amplifier by the information of magneticaction closure, its normal-closed end of the first electromagnetic relay work disconnects, the second electromagnetic relay voltage of losing the job quits work, and pumping motor power-off stops pumping.When making water tower level, water declines, float leaves high water stage tongue tube with hole circular permanent magnet, the first transistor amplifier is not worked, the first electromagnetic relay normal-closed end closure, when water tower level continues to decline, during lower than low-water level tongue tube, float approaches again low-water level tongue tube with hole circular permanent magnet, the information of low-water level reed switch contact closure compares delay circuit through second starts working again the second triode amplifier, pumping motor is switched on to having and is started to draw water, and reciprocation cycle forms tongue tube control automatic water pumping device for water.
Referring to Fig. 1, working power transformer adopting high-low pressure separates coiling, power >=3W, and secondary voltage 15V, by tetra-diode rectifications of 1N4002, the filtering of 1000U F25V electrochemical capacitor, 7812 three terminal regulator voltage stabilizings, form stable 12V working power.The first electromagnetic relay adopts direct-current working volts 12V single contact miniature relay, and the second electromagnetic relay adopts the power relay of 12V direct-current working volts double-contacts (contact capacity 20A).The first comparison delay circuit/the second relatively delay circuit adopts respectively resistance and capacitor bank, and the first/the second transistor amplifier adopts respectively the compound composition of triode of two PNP and NPN polarity.High/low water level tongue tube connects space out (its distance is to control the height of water tower pumping capacity) and is vertically encapsulated in tubule that diameter is 1.5cm with wire, low-water level tongue tube is high at the bottom of tubule 20cm, do low-water level and detect, the bottom of pipe is blocked with plug, does not allow water inlet.High water stage tongue tube does high water stage and detects.Circular magnet is selected the ndfeb magnet of the thick 1cm endoporus of diameter 3cm 2cm, embed in the north north charging tray of circle of expecting the diameter 12cm thickness 4cm endoporus 2cm making, form concentric circles with permanent magnet, be enclosed within tubule, in the water of water tower, moved up and down by buoyancy of water.When installation, tubule is vertically inserted to water tower, the lead-in wire of high/low water level tongue tube be connected to tongue tube control water plug the upper limit, lower limit, on binding post, connect 220v electricity and get final product work.
