Abstract

The utility model discloses a water tower water level automatic controller which comprises a water sensor I and a water sensor II which are respectively installed at the lower and the higher water level in a water tower; a water falling area of a water inlet pipe orifice is internally provided with a water sensor III; the water sensor I, the water sensor II and the water sensor III are respectively connected with the controller; and the controller is used for carrying out logical operation on signals input by the water sensors and controlling on-off of a water pump motor according to the operation results. The water sensor is arranged at the water falling area of the water inlet pipe orifice and is used for monitoring the water inlet condition, and the controller is used for carrying out protecting action on abnormal condition in time, so that the water pump motor can be avoided being damaged abnormally; the water sensors are arranged in the water tower, the structure is simple, and manufacturing cost and installing cost are low.

Description

The water tower level self-actuated controller

Technical field

The utility model relates to a kind of water level controller, specifically is a kind of water tower level self-actuated controller.

Background technology

Publication number is the patent documentation of CN201477451U, a kind of water level controller is disclosed, can detect water level in the container, and the control external unit is made the circuit of corresponding actions according to SEA LEVEL VARIATION, it comprises a detecting unit, detecting unit has a plurality of sense contact and a common point, a plurality of sense contact are separately positioned on different vertical height place in the container, common point is positioned at the bottom of container, and common point is connected with power supply or ground, one logic judgment unit, logic judgment unit has respectively input end that is electrically connected with a plurality of sense contact and common point and the output terminal that is electrically connected with solenoid valve, be positioned at following sense contact of waterline and common point conducting in the container and have same potential, it is unsettled to be positioned at the above sense contact of waterline in the container.But this technical scheme remains in deficiency being applied to water tower level when controlling automatically, mainly show when lack of water in the water tower but water inlet pipe freeze stop up or well very thirsty when anhydrous, controller can allow water pump ceaselessly running for a long time, makes the water pump damage easily.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model aims to provide a kind of can the obstruction or well when anhydrous at water inlet pipe, the water tower level self-actuated controller that can protect automatically pump motor.

The technical solution adopted in the utility model is: the water tower level self-actuated controller, comprise the sensor one and the sensor two that are installed in low high water stage place in the water tower respectively, sensor installation three in the water inlet pipe, sensor one, sensor two, sensor three connect controller, controller carries out logical operation to the defeated next signal of sensor, and utilizes operation result that pump motor is carried out switch control.

When water tower level was reduced to the low-water level place, sensor one was sent the lack of water signal into controller, and controller starts pump motor water tower is carried out moisturizing; When water tower level was increased to the high water stage place, sensor two was sent the full water signal into controller, and the controller motor that switches off the pump stops the water tower moisturizing.When water tower when carrying out moisturizing; when if obstruction of generation water inlet pipe or well are anhydrous; cause anhydrous passing through in the inherent setting-up time of water inlet pipe; sensor three is sent anhydrous signal into controller; controller is after surpassing setting-up time the anhydrous signal duration that sensor three is sent into, and the motor that switches off the pump is protected automatically.

Above-mentioned controller comprises the timing reset circuit.When water tower carries out moisturizing; if take place water inlet pipe freeze stop up or well temporary transient when anhydrous; when controller is protected automatically at the motor that last time switches off the pump; trigger the timing reset circuit simultaneously; after the timing period; the controller auto-initiation carries out logical operation to the defeated next signal of sensor again, and utilizes operation result that pump motor is carried out switch control.Like this, realized behind the water inlet pipe ice or well when resuming water supply, controller can start pump motor automatically and recover moisturizing, realizes that really unmanned moves automatically.

Above-mentioned controller comprises single chip circuit, interface circuit,

Above-mentioned controller comprises delay circuit, logical circuit, interface circuit, and the delay circuit input end connects water sensor three, and output terminal connects logical circuit, and delay circuit is responsible for sending into logical circuit behind the signal lag setting-up time with water sensor three and is carried out computing; The input end of logical circuit also connects water sensor one, water sensor two, and logical circuit is responsible for all input signals are carried out logical operation, and operation result is passed to interface circuit; The interface circuit input end connects logical circuit, and output terminal connects pump motor, and interface circuit is responsible for converting operation result to outside pump motor power on/off control.

The delay time of above-mentioned delay circuit is 1-300 second, and the more suitable time is 10-100 second.With suitable delay time, can reduce the energising duration of runs of pump motor under abnormal conditions, avoid pump motor impaired.

The delay time of above-mentioned delay circuit is adjustable.

The utility model beneficial effect has: 1, by the district of falling into water at water inlet pipe mouth water sensor is set, with the monitoring flooded condition, and by controller abnormal conditions is protected action timely, can avoid the pump motor damage; 2, only need in water tower, to arrange water sensor that need not to arrange, simple in structure, it is low to make installation cost in well, drinking-water pipe.
