Abstract

The utility model relates to a full-automatic controller of a water tower, which controls water towers, water pools and other liquid tanks which use a water pump, a liquid pump or a tap water spigot for water supply and liquid supply. The controller is a mechanical transmission system which is composed of a floating ball, a string and a control ball, and the controller moves along with the high-low change of water surface. The control ball is between a switch K1 and a switch K2, when the floating ball is on a lower water level, the control ball reaches the K1, the circuit control section is switched on, an alternating current contactor operates and is self-locking, and a water pump (motor) starts operating. When the floating ball reaches an upper water level, the control ball falls on the switch K2, the switch K2 is cut off, the alternating current contactor is also cut off, the water pump (motor) stops operating, and afterwards, the utility model can automatically repeat, and users' control is not needed.

Description

The water tower full automatic controller

The utility model relates to and a kind ofly carries out the device of Automatic Control by water pump (liquid pump) or water tap, supply water water tower, pond and other fluid box for liquid, especially the water level up and down in the pond of water tower is carried out Automatic Control.

At present independently the water tower pond all is by the power switch of Artificial Control water pump and water tap, and many units are responsible for pump water in the water tower by the special messenger, and ignorance is arranged sometimes slightly, will delay water or water overflows water tower.

The purpose of this utility model provides a kind of water tower full automatic controller, and it has not only replaced the problem of people's control and people's careless error, and is controlling the water level up and down in the water tower pond exactly automatically, and can regulate the height of the water level of being controlled up and down.

The purpose of this utility model is to realize like this, fix ball float and control ball respectively at the two ends of a cord, the middle part of cord is worn on the fixed pulley of two horizontal positioned, on ball float is bubbled through the water column in the inboard in water tower pond, the control ball is in the vertical garden shape tube in the outside, water tower pond, garden shape tube internal upper part has normal open switch, and normally closed switch is arranged at the bottom, and these two switches connect with lead with A.C. contactor.One end of A.C. contactor is pressed power supply, other end water pump (motor).Because ball float, cord, fixed pulley and control ball constitute a machine driven system, variation campaign with water surface height, the control ball is between normal open switch K1 and normally closed switch K2, when ball float during at following water level, the control ball arrives K1, and the circuit control section is connected, A.C. contactor work and self-locking, water pump (motor) is started working, and water is constantly pumped among the pond of water tower.When water level is gone up in ball float arrival, the control ball will drop on the normally closed switch K2, and the control ball disconnects K2 under institute's gravitate, and A.C. contactor cuts off the power supply, and water pump (motor) quits work, and will repeat said process automatically later on.

If with the tap in water tower full automatic controller control tap water supply pond, tap should be selected hand-pulling for use.The direction of closing at the end of handle adds a tension spring, make switch can turn off water, the direction of opening at the end of handle is a cord again, the other end of rope is connected on the reel, reel through driving belt by electric-motor drive, utilize the utility model motor to be connected on the output wiring terminal of A.C. contactor, up and down the position of water level and the correspondence position of K1, K2 get final product in the pond to regulate ball float again.

Owing to adopt such scheme, to water tower, pond and other fluid box, every by liquid pump or liquid switch for liquid inside, after full, close, open again after using up, so long as manually operated, all can adopt this scheme to replace people's operation, and can solve slipping up accidentally of people.This controller mainly is made up of the normal open switch K1 in ball float, cord, fixed pulley, control ball, the oval tube, normally closed switch K2 and A.C. contactor, and is simple in structure, installs easily.

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

Fig. 1 is principle of the present utility model and setting drawing (height of the long garden shell body of 1: 10 controller of scale and the pond height of water tower are as the criterion with 3 meters, if actual liquid height is low, the brachymemma of controller oval lower housing portion can be got final product).
